2 LIGHTING INDIA November - December 2015

It is quite interesting to observe how Light Emitting Diode (LED) Lamps, being the central theme of today’s lighting

technology development, have been entering for experimentation and creating excellence in different fields. With versatile capability, low power consumption, small form factors and ease of handling, LEDs are finding

wide acceptance in different application areas very fast. Let me share some interesting global facts here.

Recently, in an effort to study the effects of lighting on human health and diseases, the Smart Lighting Engineering Research Center (ERC) at Rensselaer Polytechnic Institute (RPI) installed a novel hospital inpatient lighting test bed for the study of automated lighting at the University of New Mexico Health Center (UNMHC) in Albuquerque. The result is quite positive.

Another recent instance is PhytoLux’s GBGO (Great British Grow Off) programme, through which more than 30 UK universities, colleges and research organisations tested Attis LED lights in order to establish the effect on the plants being grown and the energy being saved versus HPS lights. The programme, which commenced in 2013, ran for 18 months and was a huge success, with almost all of the trials proving that plant growth is

at least equal, and in most cases improved, by using PhytoLux lights. On an average, it offered 65% of energy saving.

In Sri Lanka, around 85,000 inland fishermen used to consume 30 million litres of kerosene annually, generating 75,000 tons of CO2 emissions. Moreover, leaking fuel repeatedly threatened the spawning areas of the shrimp. Diana Electronic, with support from Infineon and Osram as a part of the ‘LED Light for You Initiative’ has now provided them an inexpensive water-tight LED lamp, this is protecting the sensitive mangrove forest ecosystem.

Horticultural LED Products

As socio-economic changes coupled with technological advancements have initiated vast changes in our lifestyle, indoor farming is fast

paving its way to the urban society. The time is not very far when it will be a very common practice in every urban society. Anticipating the future requirement, several companies are carrying out in-depth research in developing horticultural Light-Emitting Diode (LED) products.

According to Osram, today LED lighting can stimulate plant growth by up to 40%. Philips has been developing commercial ways to apply lighting technology to crop farming for over 75 years. The company states, that with cutting-edge LED innovations at their command, they can custom-build a science-based solution for anyone. As per GE Lighting, plants require a certain radiation level to help with photosynthesis, so their researchers and product developers are working in that direction to offer even better products for horticultural lighting.

A recent report from Navigant Research states, horticultural LED products are now beginning to pick up steam as the technology and its quality advances. Today, LEDs are significantly more efficient, and the additional benefit of supplying the correct wavelengths of light to improve crop yield has made them the lighting technology of choice in a growing number of facilities. The report also says that in some regions, LEDs are expected to make up more than half of new horticultural luminaire sales as early as 2017. Thanks to LED innovators that their works are leading us towards entering a new era of indoor farming. Please e-mail me your views at [email protected]

Bavarian State Medical Board uses Osram’s solution

As part of a lighting refurbishment, Osram Lighting Solutions supplied an individual and highly efficient

lighting solution for the offices and conference rooms of the Bavarian State Medical Board in Munich, Germany. With help of state-of-the-art multi-sensors and the Dali Eco control system, suspended LED luminaires are now controlled

according to daylight, occupancy and movement. This saves up to 65% in energy each year.

The Bavarian State Medical Board with headquarters in Munich is one of 17 German medical Chambers. As the legislative professional association for 75,000 Bavarian doctors, it represents their occupational interests, promotes medical training and creates social facilities for doctors and their dependants. The office and conference rooms were upgraded in 2015 and were equipped with around 700 Arktika suspended LED luminaires. The ultra-flat, computer screen-compliant designer luminaires float by two thin wires, and create highly pleasant room atmospheres thanks to a combination of direct and indirect light components. The luminaires were also combined with state-of-the-art sensor and control technology. Multi-sensors and the Dali Eco control system implement presence and motion detection as well as control of light according to levels of daylight, and users can additionally control the luminaires individually using push-buttons (for on/off and dimming).

Passive infrared PR3 sensors are installed in the ceiling, and although hardly recognisable for observers still feature high performance. The sensors detect the presence of people at workstations and enables motion detection in the room. Control is implemented in semi-automatic mode. If an employee enters the room in the morning he presses the button to activate the lighting. The system adds the required quantity of artificial lighting according to the ingress of daylight until an illuminance level of 500 lux is achieved, as valid for office spaces. If nobody is in the room any more, lighting is dimmed down to 10% after 15 minutes and switches off completely after a further 10 minutes.

The Dali Eco multifunctional light management system is a simple plug & play solution, and commissioning can be simply and conveniently carried out using a remote control. A completely automatic nominal value setting is set with the press of a button, based on the illuminance level specified by the lighting design.

The servers offer smooth playback of up to 8K media using the leading AiM Codec plus 4 or 8 full 1080p HD outputs. The Ai R Series is the future of media technology now, direct from Avolites, ” said Avolites’ MD, Steve Warren.

Avolites’ redesigned, bespoke ISE booth featured a ‘Media Integration Focus’ area where visitors got hands on with the latest in integrated lighting and video. Visitors were also among the first worldwide to get a sneak preview of the much-anticipated Titan V10 software, which enhances the best loved features of V9.

The most striking addition was the full 3D visualiser from Capture – now fully integrated into the software. They also demonstrated the now much loved V9 features including pixel mapping, Key Frame Shape engine and fully featured theatre functionality.

The company also launched its new user designable control surfaces for Titan software. Especially designed for installers, this new API allows the user to create his/her own touch control surfaces using basic HTML skills. It also offers them to use creative skills to generate a user interface tailored for specific use, which then harnesses the power of the Titan software. It is also compatible with popular control systems such as Q-Sys and Crestron.

Control4 names top international dealers, distributors for 2016

Control4 Corporation, a well known global provider of smart home solutions, has announced the winners of its 2016 EMEA Dealer-Distributor Awards. The annual awards are given to

members of the Control4 EMEA community for superior client support, creative use of the products, record-breaking sales volume and excellence in installation. “Through dealer innovations in using Control4 products, these awards grow each year, firmly planting Contro l4 Authorized Dealers and Distributors as leaders in their respective regions. We are proud of the performance of these dealers, and we are always eager to honour their unique projects and ideas,” said Jim Arnold, Senior Vice President of Sales for Control4.

For 2016, Control4 issued a number of Dealer of the Year Awards based on sales region, with several winners in each area. Smart Synergy took home the award for UK North, Hifi-Profis was selected for Germany South, Konexions for UK South among others. Control4 also selected a number of Regional MVP award winners for 2016 including Bespoke Home Cinema, UK North; RIB AV, UK South; and The Cinema Company, London.

Leaf Fzco was named Distributor of the Year for the Europe South and Middle East sales regions, while Sweden-based Canseda was named Distributor of the Year for Europe North. Control4 awarded a number of dealers for outstanding or unique projects in 2016 across a number of categories. For whole home projects over 60,000 euros, New Wave AV was honoured for their Kent Barn conversion job, and Knektd Ltd. earned a nod for their “More than A Mews” project. Some more dealers were also honoured.

At ‘boot’ in Düsseldorf, the world's well known water sports trade show, HELLA presented the company's latest LED lighting systems for recreational boats from January 23 to 31, 2016.

HELLA's portfolio ranges from navigation lights, to deck lights, through to indoor and outdoor lights as well as accent lighting. These all make use of innovative LED technology. The topic of efficiency plays a particularly important role on board a boat. The highlights at HELLA's booth (booth G59.2, hall 10) were primarily the Sea Hawk XLB LED deck floodlight, the EuroLED 75 ceiling light and the fourth generation of the Module 70 LED work light.

With the Sea Hawk XLB LED deck floodlight, HELLA is extending its existing series to include the brightest LED version so far, with 2,200 lumens. The deck floodlight is available with three different lenses, depending on the illumination requirements. While the wide lens illuminates areas in close proximity and is ideal for applications involving the cockpit, bow or work area, the spotlight variant offers concentrated light distribution for sailing, illuminating objects in the water or docking, for example. The extra linear illumination pattern, which resembles that of a searchlight with an extremely narrow beam angle of just five degrees, is perfect for locating objects more than 30 meters away, such as buoys and landings.

The housing of the Sea Hawk XLB is also injection moulded from an innovative, non-metallic, thermally-conductive polymer. The unit can therefore withstand the harsh conditions that prevail at sea – as well as optimally dissipate the heat generated by the electronics without the need for an external aluminium heat sink.

HELLA also showcased EuroLED 75 ceiling light for indoor and outdoor lighting applications involving the flybridge, bow and cabin and washroom areas. With its Module 70 LED Generation IV, it has introduced a compact deck floodlight. For the first time, it has been possible for this compact construction to achieve LED light outputs comparable to those of xenon lights.

Lighting rental specialist HSL supplied stage lighting, sub-rigging and trussing, architectural and site-wide practical and decorative illumination, electrics, power distribution, and full public address

announcement PA - for the 2015 Opera Holland Park festival season in west London.

The three month performance run included five cutting edge opera productions staged in the tensile structure erected by the Royal Borough of Kensington & Chelsea (RBKC) in its picturesque park, with the historical ruin of Holland House as an atmospheric backdrop.

HSL has been involved as a technical production supplier for the event for the last 12 years, in which time the lighting requirements and expectations have changed radically. What was once primarily a generic rig onstage now features

nearly 90 moving lights... with another 200 light sources supplied by HSL to light the surrounding and immediately connected areas. Over the last two years, HSL has pushed towards lighting the site and gardens with an increasing amount of LED – for all the obvious reasons and because the event is also keen to be as eco-conscious as possible.

Opera Holland Park is also a project that has been nurtured by HSL’s MD Simon Stuart, who comments, “We are always delighted to be involved in this high profile event and it’s a pleasure to work alongside Opera Holland Park’s General Manager Michael Volpe and Operations Manager Kasete Skeen, together with the site LX crew, all of whom have worked hard to present top quality productions.”

by an HSL crew of seven including Jack Champion, who went on to become the Chief LX for the run of performances.

The increased moving light count and other technology onstage gave the different lighting designers involved Richard Howell, Howard Hudson, Tim Mascall and Mark Jonathan the flexibility and scope they needed to light five very diverse productions.

More moving lights on the rig also made the changeovers – up to three productions were run in rep style at any one time – quicker and smoother.

As well as the fantastic drama onstage, the emphasis on architectural and environmental lighting adds enormously to the ambience of the evening. This essential scene setting was “A primary objective of the lighting brief,” explained John.

With that in mind, HSL made available six of their new SGM G-Spot moving lights, utilised in key strategic positions around the exterior of the tensile structure, gardens, entrance ways and three large hospitality marquees.

These were chosen for their power and high impact effects, which were visible even in the twilight. As the operas started during daylight hours, it was important to enhance the environment then as guests arrived and enjoyed their pre-show mingling… as well as after dark when the impact was obvious.

StageThe production lighting rig has been developed and

tweaked by HSL over the years – also upgraded as new technology comes online – and this year featured an impressive 87 moving lights including 9 x Martin MAC 3s, 8 x Martin MAC 2K XBs, 24 x Robe ColorWash 750 Tungstens and 32 x Robe REDWash 3.192s.

These were positioned on a series of overhead and advance trusses, sub-hung from the tensile roof superstructure

that was temporarily installed at the site. This is a tricky and delicate rigging process, which has also been streamlined by the HSL team.

The moving lights were joined by 40 x ETC Source Four profiles with assorted lenses 14 of which were fitted with Chroma-Q Broadway scrollers and 16 x PAR cans with a mix of CP61 and 62 bulbs.

All these conventional fixtures were spread out across the trusses – over stage and above the audience – and on eight side-stage booms.

Two Robert Juliat Korrigan follow spots were on hand if needed and an ETC EOS console ran all the lighting via two separate partitions, one for the stage / production lighting and one for all the site elements, complete with an Ion desk for backup.

The desk was operated for the shows by Jack and his two deputy LXs, Paul Walmsley and Callum Humphries.

SiteThe site lighting was a mix of 200 practical and safety

GD Naidu Charities are the proud owners of the newly opened Ge dee Car Museum in Coimbatore, which is touted as one of its kind in India with some of the exhibited cars not to be seen

anywhere else in the country. Every significant development in the automobile industry along with a lot of wheels from all over the world is on display. It is a tribute to well-known scientist, inventor, educationalist and philanthropist Gopalswamy Doraiswamy Naidu a.k.a. GD Naidu (1893–1974), also referred to as the Edison of India. It was his dream to open a museum for displaying his private collection of automobiles, which has now been fulfilled by his son GD Gopal Naidu, the Managing Trustee of GD Naidu Charities.

The museum in fact is an expansive 20,000 sq ft basement parking lot with a layout that consists of a curving driveway leading up to the main hall. The driveway consists of posters depicting the evolution of automobiles with an Audio-Visual (AV) room at the end for theme-based shows. The main hall consists of five alternating bays of gallery spacefor visitor movement, and display space for cars, accessories and their associated documentation in the form of posters. The cars in the main hall are arranged chronologically: from a replica of the first automobile in the world to modern racing cars. Each car is provided with dedicated posters for explaining its evolution with respect to the automobile industry as a whole.During the initial stages of the project the display space was to be utilised for exhibiting only 20 to 25 cars. However, during the course of the project this collection grew to around 70 cars. Architecturally, the raw industrial look of a basement

garage has been maintained throughout the museum. With daylight being ruled out as a source of light due to

inaccessibility, track lighting seemed the ideal solution for its flexibility and raw industrial appeal. The scope was further narrowed down to track lighting using SSL technology owing to the owners’ keen drive towards energy-efficiency. Moreover, SSL could only provide the appropriate optical control required for creating visual drama. The initial brief for lighting was to provide a visual hierarchy based on the historical significance of these cars. Cars responsible for either a path-breaking paradigm shift in automobile history or any other historical event of significance were to be treated as ‘highlight’ cars with special effects. Therefore, the overall lighting strategy is based on both spatial requirements in terms of gallery and display lighting, as well as visual hierarchy in terms of special-effect lighting.

Considerable amount of research went into the lighting design process, which spanned over two years. The choice of colour temperature is based on the pigment colour of the posters or cars’ paint. For example, warm-toned pigments such as red, brown or gold are washed in 2700K or 3000K, while cool-toned pigments such as blue or silver are washed in 4000K. However, the challenge of highlighting neutral-toned pigments such as black or white is met by using their time period as a basis. For example, 2700K or 3000K are used for cars from an older time period, while 4000K is used for cars from a more recent time period.

appropriate general illumination to facilitate visitor movement. Darkness being pivotal for creating a sense of drama and mystery in a museum environment, the lighting level for the gallery is deliberately kept low. Additionally, low light-levels cause minimal light spill and non-interference with the display lighting.

3000K Abby Bro 10W track spotlights with flood optics are used for displaying the posters. A combination of ERCO Opton 12W spotlights with interchangeable spot, flood and oval-flood optics, and Prolicht Nitro 10.3W spotlights with flood optics are used for appropriately accentuating the cars. The lighting typologies applied for each car is dependent upon their size: either a spot or a flood optic for small-sized cars; a combination of spot and flood for medium-sized cars; oval-flood optics along with spot and flood optics for large-sized cars. ERCO Pollux 2W track spotlight with narrow-spot optics is used for any additional accentuation of certain key elements such as logos or insignia.

Special-effect lighting for the highlight cars is done by first providing a general wash using flood or oval-flood optics. Then its special features bearing a certain historical significance such as bumpers, headlights, hood, seats or wheels are accentuated using spot or narrow-spot optics. A combination of 2700K, 3000K and 4000K is used instead of a single colour temperature based on pigment colours. ERCO Pollux 6W framing projectors are used to highlight important

information depicted on the posters of these highlighted cars.Lighting provides an all together new dimension towards

experiencing these cars. The use of SSL technology has resulted in an LPD of only 0.15W/ft2, which is a new benchmark in museum lighting.

Zumtobel has been able to use a field study with retail chain Gerry Weber to demonstrate the significance of light in shop applications. Customer behaviour and reactions measured with implicit and explicit

methods showed that target group-oriented lighting design concepts had a positive effect and led to a 10% increase in turnover. This research is a continuation of the laboratory study in which the light preferences of seven different customer groups were analysed using a neuropsychological target group model.

A recent field study has confirmed the findings of a Zumtobel laboratory research project on the unconscious effect of light in retail stores. In cooperation with the fashion retailer Gerry Weber, it was possible to analyse to what extent targeted lighting solutions influence the buying behaviour of customers and thereby drive sales. Based on the Limbic Types identified by the laboratory study in 2013, the target groups of the Gerry Weber brand could also be specifically examined.

The Gerry Weber shop in Herford, Germany, was the location for the field test. The lighting concept was the only element that was changed in the store, which has now been open for a year. An LED spotlight solution from Zumtobel was installed specifically to meet the preferences of a key target group for Gerry Weber, the so-called Harmonisers. Harmonisers belong to the BALANCE Limbic Type, and therefore react positively to moderate accent lighting. As a result, the new look of the retail space in Herford was carefully designed to generate a bright and friendly atmosphere with a warm colour temperature of 3000 Kelvin.

General purchasing behaviour before and after the installation of the new lighting solution was then measured and observed over two months. In addition, certain customers were tested using the Limbic Emotional Assessment (LEA), a

method developed by GruppeNymphenburg, who worked with Zumtobel on this research project. LEA is able to empirically capture the slightest unconscious physical reactions, including brain activity and heart rate. Some customers were also interviewed about their shopping experience and turnover was compared with an equivalent reference store for the same period.

The results were clear adjustment of the lighting situation to reflect typical target group preferences delivered a 10% increase in turnover compared to the reference store. Further analysis also revealed an even higher average sales increase amongst the specific target group for which the lighting solution was optimised.

Implicit measurements revealed an overwhelmingly positive emotional response from Gerry Weber customers to the newly installed Limbic Lighting concept, particularly when compared with the original shop lighting. Explicit questioning also gave customers the opportunity to say how much they appreciated the positive atmosphere generated by the new Limbic Lighting solution.

The reference store used to contrast the results of the field test was carefully chosen for its equivalent size, shop design, customer demographics and geographical proximity to Herford. Looking at the national picture, the branch with the Limbic Lighting concept saw above-average sales when compared with all HOUSES of GERRY WEBER across Germany.

Reactions measured using the LEA methods demonstrated greater potential for buyer activation in response to Point Of Sales (POS) displays in Herford.

This means that customers showed a greater level of interest in the retail space and the products on offer, leading them to spend more time in the store. At the same time, analysis of the data showed how participants felt relaxed and exhibited fewer signs of stress.

Head of Retail Operations at Gerry Weber, Hörschläger Martin, was delighted with the outcome. Gerry said, "For us as an international fashion brand, it was fascinating to see clear scientific findings that prove the significant influence of light at the POS."

"The cooperation with Zumtobel was extremely positive and ultimately the key to us understanding and then responding to the light preferences of our target group. We have seen how profitable the Limbic Lighting concept proved in our Herford store, with a marked increase in sales during the test period. In comparison with the reference store, the retail space with the optimised Limbic Lighting solution achieved up to 10% more turnover,“ added Gerry.

Ralf Knorrenschild, Senior Vice President Global Key Account Management Zumtobel, was equally enthusiastic. In the words of Ralf, "This positive result confirms our view that light offers the greatest potential for sales growth at the POS a fact that has often been overlooked. With Limbic Lighting,

we have managed to realise an exciting new form of buyer activation for our customers.“

The laboratory study The most recent research in the area of neurosciences has

shown that more than 80% of buying decisions at the Point Of Sale (POS) are made unconsciously, mainly depending on influences addressing people's emotions.

However, the effects of light have so far been evaluated only by means of various questioning techniques, without taking the decisive aspect of the unconscious into account.

For that reason, Zumtobel Research jointly with Gruppe Nymphenburg, a Munich-based consultancy and market research institute, initiated a laboratory study in order make the emotional effects of light on customers measurable empirically, recording their physiological responses.

For the laboratory study, the researchers used the “Limbic Model” developed by Gruppe Nympenburg, which focuses on the complex emotional personality structures of consumers. The subjects were assigned to seven different personality types, the 'Limbic Types', using a questionnaire. These included the 'Bon vivants', the 'Hedonists', the 'Adventurers', the 'Per- formers', the 'Disciplinarians', the 'Traditionalists', and the 'Harmonisers'. The objective of the research project was to find out how these seven groups respond to various lighting scenarios at the POS. For this purpose, a new method developed by Gruppe Nymphenburg was used, the 'Limbic Emotional Assessment' (LEA).

Using this method, even the most minor physical responses can be measured. In the laboratory experiment, the subjects successively looked at 20 different lighting scenarios with various ambient and accent lighting features, colour temperatures, contrasts and light quantities.

While doing so, their unconscious physical reactions, including brain waves and cardiac activity, were empirically measured. Based on the psychophysiological data collected, it was possible to clearly establish which of the lighting scenarios' parameters triggered positive or negative emotions, stimulation or relaxation in specific target groups.

The findings obtained clearly show that there is an optimal way to address each individual target group. It has also turned out that there is no single lighting scenario that has the same markedly positive impact on all 'Limbic Types'. There are, however, individual lighting profiles that several types respond positively to.

Three main groups were identified, each with similar requirements as to lighting solutions: the first group, BALANCE (Harmonisers, Traditionalists and Bon vivants), responded particularly positively to moderate accent lighting. The second group, STIMULANCE (Hedonists, Adventurers),

responded most positively to lighting scenes with relatively strong contrasts, created by accent lighting and a variety of different spots.

Group three, DOMINANCE (Performers, Disciplinarians), responded sensitively to unbalanced lighting concepts and can best be loaded with positive emotions through balanced, moderate effects. However, narrow-beam lighting with extreme contrasts triggered negative emotions in this group.

About the research methodThe Limbic Emotional Assessment (LEA) research method,

which has been developed by Gruppe Nymphenburg, is based on methods used in neurosciences as well as psychophysiology. The latter discipline is concerned with the relationship between brain activity and the related physical responses. In combination with Limbic, a brand and target group navigation model tried and tested in practical applications, LEA allows for a distinction according to specific target groups. In doing so, the scientifically tested LEA method combines five different parameters that capture even the tiniest of physical reactions.

From brain waves and skin conductance through to cardiac activity, numerous physical reactions of customers are measured to draw conclusions on their emotional state.

he Baku Crystal Hall is a modern, multi-functional event arena with a capacity

of 23,000 spectators. Located near National Flag Square on the coast of Baku,

Azerbaijan, design and construction had to be completed in only nine months,

just in time to host the hall’s first major event, the 2012 edition of the Eurovision

Song Contest. The 206-metre-long and 168-metre-wide steel construction is

coated with a slightly transparent, illuminated membrane facade, which lends the

building its characteristic crystalline appearance. The lighting concept was

designed to serve the crystal volume and the character of the event.

The dynamic lighting facade became an essential part of the choreographic show concept of the Eurovision Song Contest 2012; right before the performances of the artists the respective national flag was shown on the facade in a more or less abstract way and was integrated into the television production, just as virtual camera flashes. The intelligent lighting control system made a flexible programming possible and allowed new options for the future and opened the gate for the special visual needs of upcoming events...

Each point of light of the facade is designed as an integral part of the facade structure and consists of two independently controllable RGB LED light sources. One light source glows directly, while the other one generates an indirectly reflected corona on the membrane; this results in a much softer appearance. Furthermore, special colour contrasts can be achieved with the separately controllable foreground and background colours...

Each point of light in the chain is individually controllable, equipped with 9 SMD RGB LEDs, and was equipped with a diffuser dome. Also, the technical bodies of the LED luminaires have been encased to optimise the appearance of the illuminated facade. Due to the very short planning and construction period, it was absolutely crucial to resort to a proven lighting product available in the market...

The installation on site had to occur fast and uncomplicated, so that the choice fell on a LED RGB chain that could be variably preconfigured in different lengths. A total of 1080 LED chains with 12 different length configurations were applied.

On the initiative of the Comune di Roma Capitale and Mayor Ignazio Marino, with thanks to the Sovrintendenza Capitolina, and with the planning support of Unilever Spa, the extensive

area of the Fori Imperiali (encompassed by the Capitoline, Palatine and Quirinal hills) is the focus of a major illumination project entrusted to Professor Vittorio Storaro – who has won numerous international awards, including three Oscars, as the cinematographer of such masterpieces as Apocalypse Now, Reds and The Last Emperor – and to architect Francesca Storaro, the lighting designer on various high-profile international projects.

The working drawings, specifications, bills of quantities and installation of the system are being managed and supported by Acea Illuminazione Pubblica S.p.A.

Forum of AugustusThe metaphor that best describes the creative route that

led to the concept for the lighting of this section is the journey that leads from the Earth to the Heavens: it is a route that starts with the seed sown by Julius Caesar during the Republic and ends with the harvesting of that seed by Augustus in the form of the Empire. Rome rose skyward through its knowledge, its organisation and its civilisation, illuminating the known world like a sun. The central idea for the illumination of the Forum of Augustus carries within it the image of a light wave, which rises from the ground, starts to envelop the Temple of Mars Ultor with great luminous intensity and, while slowly fading, rises upwards to embrace the whole perimeter of the wall that surrounds – with the two Exedrae – the Forum, doing so unidirectionally, like the architecture of the Forum itself.

But Augustus was also the herald of the Pax Romana, symbolised by a light coming down from above with a lunar softness. The Forum area surrounding the Temple is, accordingly, lit from above, as if it were a form of protection delineating a privileged area, with neutral, soft, even lighting that casts the Forum as a stage on which an act of the History of Rome is played out.

Forum of NervaJust as the illumination of the Forum of Augustus finds its

equilibrium amid the selective, unidirectional, even and suffused light, so does the lighting of the Forum of Nerva – known originally as the Transient Forum – seems to complete and define the expansionist ambitions of the Empire. The right side, which delineates the Forum itself (where the columns that made way for the Temple of Minerva were aligned), sees a series of lights that axially provide upward lighting that defines a specific space – that in which the Temple of Minerva was erected. Above the line of the wall, a second series of lights, characterised by the same sense of unity, illuminates in an even, soft and neutral way all of the

central ground of the Forum itself. Against this backdrop of lunar uniformity, other architectural elements emerge that composed the plinth of the Temple of Minerva: the Pronaos, illuminated in such a way as to highlight its ancient splendour, and the so-called ‘Colonnacce,’ which are lit from the base upwards, with a specific directional axiality at the columns themselves.

Trajan’s ForumTrajan’s Column serves as the centrifugal focal point of

Trajan’s Forum, seeming as it does to push outwards from a centre, as if dragged by someone wanting to generate a wave of light that embraces the surrounding space. For this reason, the lighting concept takes its cue from Trajan’s Column, which itself seems to emit light, centrally, through a series of soft lights that trace out the perimeter of its square base. The light continues its journey, rising up on the circular column, thanks to two circles – concentric to the column itself – of selective lights that tell the whole story of the epic accomplishments of the Emperor. While the parallel columns that delineate the Basilica Ulpia are illuminated from below, the centre of the basilica is lit by a series of projectors that appear to rise up from the ground and that, in front of each column, extend their luminosity so far as to come up against a similar radiance generated by another series of lights that, in a

centripetal attraction, merges with the first series, illuminating the entire floor of the basilica uniformly. The initially centripetal light becomes centrifugal, expanding throughout the world, like a luminous river.

Technical reportIn all of the illumination of the Imperial Fora, ERCO LED

luminaires will be used, along with a small percentage of Guzzini luminaires, as per the indications of the final design. Across an area of around 20,000m2, there will be a consumption of just 26 kW with a total of 520 projectors. All of the LED luminaires used have specific illumination characteristics, with patented optical systems, such as ERCO’s Spherolit collimators and lenses. The selected ERCO projectors guarantee efficient visual comfort and an extensive array of optics: narrow spots, spots, floods, wide floods, oval floods, wallwashers with various power classes and an exceptionally high level of design precision.

All of the luminaires also feature additional filters designed specifically for the ‘Imperial Fora in Rome’ project by Francesca and Vittorio Storaro, made by ERCO. The families of ERCO projectors used on the project are as follows: Lightscan, Parscoop, Grasshopper, Beamer and Focalflood. For the LED linear bars, luminaires from iGUZZINI’s Linealuce Compact and Mini families were selected. The colour temperature of the selected luminaires (both ERCO and iGUZZINI) of the LED sources will be White 3000k for the main architectural element of each Forum, and White 4000k for the remaining part of the Fora.

In relation to the Forum of Augustus, the main element will be the Temple of Mars Ultor, for the Forum of Nerva it will be the ‘Colonnacce’ and the plinth of the Temple of Minerva,

and for Trajan’s Forum it will be Trajan’s Column. All of the projectors are managed by a HELVAR control system, which makes it possible to adjust with absolute precision the light intensity of the LED lights, both with DALI and dimmable projectors. Each Forum will have a separate control board, located internally to protect it against inclement weather.

What is your comment on the growth of the global lighting industry?

The global lighting market is currently undergoing a radical change. Fueled by the exponential urban growth expected over the next decade and the drive towards ever greater energy efficiency, the market is transforming from conventional to energy efficient lighting technology. According to a McKinsey report, the industry is expected to touch EUR 90 Bn by 2016 at a CAGR of 6% and will cross the EUR 100 Bn mark by 2020.

Various mega trends such as global population growth and urbanization are increasing the overall demand for lighting products. At the same time, resource scarcity and climate change are of increasing concern. Governments around the world are responding to this with greater regulation towards energy efficiency, and the lighting industry is addressing the issue by pursuing the development and enhancement of more energy-efficient lighting technologies.

Despite fluctuations in the economy and the general lighting industry, the outlook for the LED lighting market is very bright. Due to the significantly increased energy efficiency, LED lighting continues to occupy a significant portion of the overall lighting market. The market penetration rate of LED lighting is projected to climb from 31% in 2015 to 54% in 2018 according to Strategy Unlimited Luminaire Report 2015. Forbes has predicted that the LED market will continue to grow throughout the next decade, with the global market share reaching above 70% by 2020. Due to prosperous architecture market during urbanization and the governments’ strong support for energy saving lighting, Asia has strong demand for LED lighting products.

How is Covestro India contributing to this journey?The population growth and rapid urbanization coupled

with growing concern towards climate change has unlocked vast potential in India for LED lighting. The low energy consumption and long service life of LEDs offer wide-ranging potential for a host of applications. But despite the numerous advantages the Indian manufacturers rely heavily on imported lighting parts due to limited availability of LED technology in India. To overcome this barrier, Covestro India – through its facility in Greater Noida – has started manufacturing raw materials with a vision to encourage local manufacturing and faster product development.

With our technically capable dedicated support team, we offer range of polycarbonate resins and blends, along with design support, for designers and manufacturers in the LED lighting industry. We help in guiding the customer to design smartly and increase overall production efficiency with the advanced solution from Covestro.

How are the polycarbonate materials supporting the innovations in LED lamp?

Glass and transparent plastics have long been used in the lighting industry for various aesthetics and functional purposes. As the lighting industry evolves, there has been

growing interests in plastics, especially polycarbonates, due to its unique properties and versatility.

Ever since the invention of polycarbonate, in 1953, by Hermann Schnell at Covestro R&D Center in Germany; it has remained as the material of choice for the electrical industry in various applications for more than 60 years.

For the LED applications, Covestro provides the solution from its broad portfolio of polycarbonate grades that are eminently suitable for the LED market. In addition to high light transmission, all our grades display good heat resistance, excellent stability when exposed to LED luminous flux, outstanding flame-retardant properties, and a number of special features that are ideal for a wide range of LED applications .

Makrolon polycarbonate from Covestro is used for making optics, diffusers, reflectors, housing and thermal conductive heat sink applications of LED lighting. It is available in Resin as well as semi finished products (Film & Sheet) form. The material provides high purity and excellent light transmission qualities.

Who are your major clients from lighting industry?We have partnered with all the major industry leaders and

are constantly in conversation to add more partners. We are also involved in the joint development of futuristic LED luminaries with our key customers.

What are the new lighting-centered (peripheral) areas that may benefit from Covestro’s products?

Our innovative polycarbonate products provides manufacturers and designers a lighting materials toolkit to expand the realm of application possibilities. Our products can be used to efficiently manufacture parts with complex geometries, giving OEMs virtually unlimited possibilities for design compared with glass.

Our recent innovation, combining thermally conductive Makrolon TC8030 polycarbonate with polyurethane encapsulation technology utilizing Bayflex polyurethane Reaction Injection Molding (RIM) technology offers unique advantage for electronic manufacturers by reducing the number of components while creating a finished part in a mold without additional manual assembly. In comparison to traditional manufacturing, the benefits of this process include:• lower processing cost• improves thermal conduction• reduces the bill of materials• increases manufacturing flexibility, and• reduces the weight for many electronic components.

We also offer polyurethane based adhesive (for LED Chip Board assembly), coating materials (Thermally stable coatings) and Transparent Cast polyurethane (Innovative solid Light guides & Flexible light guides) towards the innovations in LED applications.

polycarbonate grades, Covestro has solutions to meet OEMs’ lighting material and technological needs. Our highly reflective Makrolon, with the white reflective surfaces, is another innovative solution that can potentially replace the metalized reflectors without any secondary operation steps in making LED luminaries.

Today, especially after Paris summit, all nations are seriously thinking of energy savings… How is Covestro helping the mission of energy savings?

Sustainable thinking and acting is imperative to preserve our planet and improve the quality and safety of the lives of millions. Covestro is committed towards innovation of sustainable materials that help in conserving resources and in reducing energy consumption and emissions of greenhouse gases.

We contribute to this goal with products and technologies that benefit society – and reduce the impact on the environment. This is the basis of the company’s vision ‘To make the world a brighter place.’

As per the UNEP statement, electricity for lighting accounts for approximately 15% of global power consumption and 5% of worldwide Greenhouse Gas (GHG) emissions.

A switch to efficient on-grid and off-grid lighting globally would save more than $140 billion and reduce CO

2 emissions

by 580 million tonnes every year. A simple phasing out of inefficient lighting could reduce

carbon emissions cheaply and easily making it one of the most effective and economically advantageous ways to combat climate change.

As a leading materials supplier, Covestro develops and manufactures products that are used in many areas of daily life – at home, at work, on the move and in recreation. Several of these products support tackling the challenges of climate changes and the environment.

Especially our solutions to LED will benefit the manufacturers with (approx.) 20% cost savings in their end product and increase the productivity compared to the traditional manufacturing process – in doing so we stand committed to the energy saving mission and drive by the Indian government as well.

We offer support in designing, material selection, and process and flow design for developing new engineering products.

We also offer onsite support for trials, testing and pilot runs of the prototype product. Moreover, we are also involved in the joint development of futuristic LED luminaires with our key customers.

What would you like to communicate to the decision makers of Indian lighting industry?

Indian Lighting Industry has been growing steadily at 10% CAGR for the last few years. The growth has remained consistent, even when there has been ups and downs in many other sectors due to the slump in the recent past in the world.

The consistent favourable policy by the Government of India is one of the major factors for rapid development of the light industry in India. The Government of India’s policy of rural electrifications and infrastructural development covering urban housing, roads and other projects has created new demand for lighting products. The push for LED lighting under the Domestic Efficient Lighting Program is another step in the right direction and will provide long term benefits in terms of efficient power usage and sustainability in the lightning industry.

We would urge the Indian government to collaborate from the initial stages. We can help the government with our global knowledge and application expertise to play a vital role in setting standards in lighting industry. The absence of national standards for lighting and luminaries manufacturing is resulting in import of s u b - s t a n d a r d products, which in turn is hampering the growth of local players – and is also eroding c o n s u m e r confidence in new energy efficient technologies.

Predicting the pace and direction of change in the retail environment is traditionally difficult. Although customers are looking for experience and digital interaction, there is no set formula for how this

actually translates in-store. One thing however is guaranteed: Energy efficiency will still be on the store manager’s agenda for 2016 and beyond. Fred Bass, Managing Director of Neonlite International Ltd, brand owner of MEGAMAN, shows how the latest LED technology can be used to shine a new light on white textiles as well as save retailers money and energy.

Bringing whites to life with LEDsIn the dim and distant past, lighting turned on, off and

could sometimes be dimmed. It came in warm or cool white and a variety of beam angles. Thanks to the latest in LED technology, it is now possible for retailers to choose the lighting, based on what they are displaying in-store. Although supermarkets have long been using red-enhanced LED lighting to enhance the vibrancy of meats and fresh produce, it is now possible to bring the same level of lighting drama to white textiles - creating cost and energy savings whilst bringing whites to life.

Get more from your lighting

LED lighting has been developed to deliver the most light as efficiently as possible. However, to achieve this, some colours on the light spectrum that are hardly visible to the human eye have been omitted. Although this isn’t a problem in everyday retail lighting scenarios, it does cause white textile fabrics to appear less vibrant than if they were lit by natural daylight.

To overcome this problem and bring the vibrancy back to white textiles, a new breed of LED lamps is now available, using to MEGAMAN’s Perfect White technology. By manipulating the phosphors on a traditional blue LED, a near-visible, violet light is emitted from MEGAMAN’s Perfect White LED lamps. This violet light excites the Fluorescent Whitening Agents (FWAs) in textiles and they begin to absorb and emit light, causing the white item to stand out from its background. Importantly, the violet element within MEGAMAN’s Perfect White technology leaves the rest of the spectrum unchanged, so other colours maintain their vibrancy as well, resulting in a perfectly lit product range that stands out from the background.

MEGAMAN’s Perfect White technology is available in a range of colour temperatures, from warm white (2,800k) to cool white (4,000k), and offers retailers the superb efficacy and energy efficiency, they have come to expect from LEDs. The Perfect White range includes MEGAMAN Vito and Carlo LED Downlights, Modena LED Tracklights and retrofit LED AR111 reflector lamps for any new or retrofit application.

By using MEGAMAN’s Perfect White LED technology, white textile products leap out from any background, increasing contrast and making a big impact with customers. Since it was launched, to critical acclaim at Hong Kong International Lighting Fair (Autumn Edition) 2014, retailers that have been trialling the new technology have noticed the difference, and the results have been very well received by staff and customers alike.

With Perfect White promoting drama whilst saving money and energy at the same time, this new technology provides retailers and store designers with exciting opportunities in 2016 and beyond.

Barbara Walters described it as “a little slice of heaven.” The National Geographic has declared its namesake lake to be one of the five most beautiful in the world. No wonder the rich and famous from all walks of life have

flocked to this idyllic Idaho city. Coeur D ‘Alene’s paradisiacal pleasures are evident throughout the year, but at no time does the city glitter quite so brightly as it does during the Christmas season – when it hosts its holiday lightshow, an event so spectacular it’s been featured on Good Morning America.

Official estimates place the number of lights involved in the show at 1.5 million. This year another 14 fixtures were added to the holiday mix, in the form of COLORado 4 IP LED linear washes from CHAUVET Professional, provided by AMP’D Entertainment.

Parkside Building. The COLORados were permanently positioned around the building earlier in 2015 to decorate it in richly coloured light, not only during the holidays, but throughout the year.

Towering over the city’s downtown, The Parkside Building includes three floors of upscale retail establishments and 17 floors of luxurious condominiums. Aside from offering well-heeled residents unparalleled views of the lake, the orange-tinted tower has also become a local landmark since it was completed in 2008. The most prominent building in town, it can be seen from virtually anywhere in Coeur D ‘Alene. For many the tower, which was originally planned as a nine story structure but was more than doubled in size to meet the demand for condos, serves as a directional reference point (as in ‘it’s three blocks north of Parkside’) as well as a source of community pride.

In recognition of their building’s stature both literally and figuratively in Coeur D ‘Alene, its management and condo-owners felt it was only proper to celebrate the structure by illuminating its exterior in coloured light. “I believe the goal in installing the lights was to create some excitement around the building and connect it more closely to ceremonies the town of Coeur D’ Alene has during the holidays as well as at other times,” said Justin Hass, Founder and General Manager of AMP’D Entertainment.

The building’s management team contacted Haas after seeing the work AMP’D Entertainment did using CHAUVET Professional fixtures to colourise two 225-foot towers at Steam Plant Square an iconic multi-use center in nearby

Spokane, Washington. In addition to looking at the COLORado fixtures offered by AMP’D Entertainment, the building’s management brought in other fixtures for a shootout.

“They found that no other light they looked at came close to the output and the saturation of the Colorado 4 IP’s, so they confirmed our proposal and actually hired their own electrician to install the fixtures with our guidance,” said Haas.

The COLORado 4 IPs encircle the 65 meter high rectangular concrete structure to bathe it on all sides in rich and realistic RGBW colours. The colors used to wash the building will vary depending on the time of year, local events or holidays. Often multiple colors will appear on the building, such as red, white and blue for the Fourth of July.

Positioned above the building’s second story retail level, the 40-watt fixtures, which have 15-degree lenses, possess enough throw distance to reach the top of the tower with ease. Extending out 1.5 feet from the building, the IP66 rated COLORados are mounted on customized bracket structures that conceal the cabling, which connects to power sources in the second floor.

“The project went off very smoothly and everyone seems very happy. The Parkside Building is a prominent structure in town. There’s a good feeling that comes from knowing our lights have helped it connect to the community in new ways during the holidays and at other times of year,” said Haas.

Revolutionary New I-Pix Db1 Fixture Makes Dance Event Debut At 10X10

T LIGH

TING

i-Pix’s unique new db1 video / beam light-source made its UK dance event debut at the 2015 Manchester International Festival (MIF)’s ‘10x10 Day & Night’, a special two night collaboration between MIF and The

Warehouse Project (WHP) to celebrate 10 years of both events in the city of Manchester.

Manchester based lighting specialist dbn was providing lighting and visuals. When the organisers confirmed they wanted something inventive and different, the db1s were proposed by dbn and i-Pix’ Chris Ewington… and they found the additional production budget needed for the 23 fixtures to grace the main stage at the Mayfield Depot.

Jon Drape, MD of Ground Control which co-ordinates all production for the WHP organisers, commented, “We've been waiting to get the DB1s on a show since Chris first invited us to see the fixture in development. The unique collaboration between the Warehouse Project and Manchester International Festival was the perfect opportunity. The db1 is a ground-breaking product, and like the audiences, we were completely blown away with its impact.”

The db1s were used on the second of the two 12 hour events, which ran from 2 p.m. to 2 a.m. at the cool occasional venue and former train station in the heart of the city.

“It was a perfect opportunity to show the versatility and high impact of the fixture,” commented db1 inventor Chris Ewington, who was delighted with the results.

Twenty-three db1s were arranged in four pyramids stacks on the main stage for the evening which was headlined by Carl Craig and Mike Banks.

The db1s were run as both a lighting and a video fixture.Video sources were fed into them via an Avolites Ai Infinity

X8 server run by Chris from a Tiger Touch II console, which produced beautiful organic and powerful mesmeric patterns and movement.

These effects were further enhanced as the db1’s 15 powerful LED cells were manipulated by being mapped, with strobing and intensity run as a lighting fixture by Edwin Croft from his Avo Pearl Expert console.

Chris ran a selection of original content through the fixtures while Edwin added a whole new dimension of

patterning, spirals and swirls, etc. which really brought a 3D element as well as intense luminosity to the output.

Working together, the two of them effectively made the db1s a moving lightsource with a huge repertoire of individual, never-repeated liquid and flowing effects and looks in a wide range of rich, distinctive colours.

Combining the two modes of operation enabled Edwin to chop the light sources in and out, so when db1s were the only light on in the room they delivered huge slices and beams of textured light.

Chris approached the media server almost like a morphing gobo. While the video content will always stay on the ‘surface’ of the db1, the beams of light shooting out from the LEDs inside and being moved by the video means the units can work as a perfect companion to any moving or static lightsource also on the rig.

The strobing is also an incredibly potent effect. The precision of the db1’s LED lightsource when pulsed

means that the eye can see the different colours changing as the light is emitted, giving nanosecond hits of incredible split-colour light.

Tweaking the LED oscillations results in extremely trippy sequences.

Says Chris, “I had the privilege of designing and operating at these two very special nights. It was an exciting and creative journey made all the better by a great team working with me behind the scenes. Good on them for having the balls to try something new!”

A week earlier, Chris had operated 24 db1s for a Charlatans gig at Castlefields Arena in Manchester, when he ran them more in conventional lightsource.

After that he reprogrammed the desk so he could access different media server clips on the bump buttons, ideal for the more ravey and improvisational style of operation appropriate for 10x10.

It’s not an understatement to say that everyone was blown away with the results!

“They are new, properly different, definitely exciting … and were the highlight of a fantastic event,” declares Pete from dbn.

AN EFFICIENTHPF LEDDRIVER WITH ZEROVOLTAGE SWITCHING

EDs are the fast emerging technology and have a wide range of applications. Due to the increased popularity of LEDs, the LED driver design should be simple. The LED driver may be a single stage driver or a two stage

driver. The single-stage approaches are derived by integrating the PFC converter and the DC/DC converter. By sharing one active switch and the control circuit, the single-stage converters have the advantages of less component count and are cost effective solutions. They are less expensive. The two-stage approach includes a PFC semi-stage to shape the input current into a sinusoidal waveform and a DC/DC semi-stage to regulate the output voltage. These two-stage approaches have the advantages of good performance, fast output dynamic response, and easy control. They require two power-conversion processes and are energy inefficient. There are many topologies using single stage and two stage converters based on different applications. In both single stage and two stage converters, the active switches are operated in hard switching mode. Hard switching increases the switching losses.

Hence, the objectives are to improve the power factor of the LED driver system for economical operation and to reduce switching losses by using a suitable technique. To reduce the switching losses soft switching techniques can be employed. By using zero voltage switching, i.e., the voltage across the device is reduced to zero before the current increases, along with the help of phase shift full bridge PWM converter switching losses can be reduced. Therefore, a new two stage topology can be introduced which will improve the PF and reduces the switching losses. A buck converter can be used to drive the LEDs with required voltage.

The circuit configuration and operation of the proposed topology is given in section II. Section III deals with detail circuit analysis. An illustrative design example and MATLAB simulation results are given in section IV. Section V is the hardware implementation and obtained waveforms. Section VI gives the conclusion of this paper.

Circuit Configuration And OperationFig. 1 shows the block diagram of the proposed

topology. It consists of a diode bridge rectifier, buck-boost converter and a buck converter. The diode bridge rectifier

converts the input AC voltage to DC. The buck-boost converter performs the function of PFC, and the buck converter steps down the dc-link voltage to drive LEDs. Both active switches can operate at Zero-Voltage Switching-on (ZVS) to effectively reduce the switching losses. To achieve the PFC function, it should be designed to operate at Discontinuous-Conduction Mode (DCM). The buck converter can be designed to operate either in

Continuous-Conduction Mode (CCM) or in Dis-continuous Conduction Mode (DCM). Continuous-Conduction Mode (CCM) has the advantage of small current ripple. At the same time an inductor of higher value is required for operation. Hence the latter method is preferred. The circuit diagram for the proposed topology is shown in Fig. 2.

The first stage is a buck-boost converter consists of diodes D5 and DS1, an active switch S2, two coupled inductor Lp1 and Lp2, and a dc-link capacitor Cdc. It serves as the PFC circuit by wave shaping the input current to be sinusoidal and in phase with the input line voltage. The second stage is a buck converter consisting of diodes D6 and Ds2, an active switch S1, an inductor Lb, and a capacitor C0. Diode D6 is used to block the reverse current of buck inductor and can be removed when the buck converter is operated at CCM. Instead of using a single inductor, two coupled inductors along with a blocking diode (D3) are used to accomplish buck buck-boost conversion. The turns ratio of the two coupled inductors is designed to induce voltage on Lp2 to block the current from the line source. A small low-pass filter, Lm and Cm, is used to remove the high frequency current harmonics at the input line. MOSFETs S1 and S2 are the bidirectional switches. Each switch is composed of a transistor and an anti-parallel diode. The MOSFET’s intrinsic body diodes D1 and D2 are used as the anti-parallel diodes. For dimming operation, the active S3 is placed in series with the LED string. Switch S3 is controlled by the scheme of low-frequency pulse-width modulation. The active switches S1 and S2 are alternately Fig.1. Block Diagram...

driven by two gated signals, vGS1 and vGS2. They are non-overlapping and complementary rectangular-wave voltages with a short dead time at the high switching frequency fs. The dead time is the time interval when vGS1 and vGS2 are both zero. Neglecting the short dead time, the duty cycle of vGS1 and vGS2 is 0.5. For simplifying the circuit analysis, the following assumptions are made: • All the circuit components are ideal. • Vdc and Vo can be regarded as constant voltage sources.

The input low-pass filter formed by Lm and Cm and the diode bridge rectifier can be replaced with the voltage Vrec. The output LED string can be replaced with its equivalent resistance RLED. At steady state, the circuit operation can be divided into six modes in each high-frequency cycle. For simplifying the circuit analysis, the low-pass filter and the diode rectifier (D1- D4) is represented by the rectified voltage Vrec and the LED string is represented by its equivalent resistance RLED. Fig. 3 shows the six modes of operation. The circuit operation is described as follows.

Mode I (t0<t<t1)This mode begins as soon as S1 is turned OFF. The current

ib diverts from S1 to DS2. The voltage across the buck inductor is equal to V0 and ib starts to decrease from a peak value. At the same time, the voltage across the buck-boost inductor Lp1 is equal to the rectified input voltage Vrec Since the buck-boost converter is designed to operate at DCM, the buck-boost current ip1 increases linearly from zero with a rising slope that is proportional to Vrec. The theoretical waveforms of buck converter are shown in Fig. 4. In the initial stage of this mode, ib is higher than ip1. Parts of ib flow through DS2, while the rest of ib is equal to ip1 and flows through Lp1, diode bridge rectifier and the line-voltage source. Since DS2 is on, the voltage across S1 is clamped at -0.7 V. After the short dead time, vGS2 becomes a high level.

Switch S2 does not conduct current until the rising current ip1 becomes higher than the decreasing current ib and then, the circuit operation enters Mode II.

Mode II (t1<t<t2)In this mode, S2 is on and ip1 is higher than ib. There are

two current loops. Parts of ip1 are equal to ib and flows through D6, Lb, Co, Lp1 and the line-voltage source, while the rest flows through Lp1 and the line-voltage source.

The voltage equations for vb and vp1 are the same as

those in Mode I. The current ib keeps decreasing. Now ip1 keeps increasing. If the buck converter operates at DCM, the circuit operation enters Mode III as soon as ib decreases to

zero. If it operates at CCM, the circuit operation enters Mode IV at the instant time of turning OFF S2. The current ib is zero. S2 is kept at on stage and ip1 keeps increasing. This mode ends at the instant time of turning OFF S2 and the circuit operation enters Mode IV.

Mode IV (t3<t<t4)At the beginning of this mode, ip1 reaches a peak value.

In order to ensure the buck-boost converts ip1 on operation, ip1 should be diverted from S2 and flows through Lp1, Lp2, D5, and DS1 to charge the dc-link capacitor Cdc when S2 is turned OFF. For this, the voltage across the inductor Lp2 must be higher than the amplitude of the input voltage to block the current from the ac line source. By this way, the diode-bridge rectifier is reverse-biased. Currents ip1 and ip2 will be equal and flow through diode D5 Current ip1drops and ip2 rises dramatically at the switching-off instant. The negative DC-link voltage is imposed on the coupled inductors, and both ip1 and ip2 decrease linearly. Regarding operation of the buck converter, since DS1 is on, the voltage across Lb is equal to Vdc-VO and, ib rises linearly. In the initial stage of this mode,

ip1 (ip2) is higher than ib. Parts of ip1 flow through DS1 to charge Cdc, while the rest of ip1is equal to ib and flow into the buck converter. Since DS1 is on, the voltage across S1 is clamped at -0.7 V. After the short dead time vGS1 becomes a high level. S1does not conduct current until the rising current ib becomes higher than the decreasing current ip1, and then the circuit operation enters Mode V.

Mode V (t4<t<t5)In this mode, S1 is on and ib is higher than ip1. There are

two current loops. Parts of ib are supplied from the DC-link voltage and the rest of ib is equal to ip1 and flow through Lp1, Lp2, and D5. Both the currents ip1 and ip2 keep decreasing. The circuit operation enters Mode VI when ip1 and ip2 decrease to zero.

Mode VI (t5<t<t6)In this mode, S1 is remained at on stage and ib keeps

increasing linearly. This mode ends at the time when vGS1 becomes to a low level to turn OFF S1, and the circuit operation returns to Mode I of the next cycle.

Design And AnalysisThe anti-parallel diode of the active switch of one

converter serves as the freewheeling diode of the other converter, the features of the buck-boost and the buck converter can be retained.

Therefore, the two converters can be analyzed separately. An LED driver for 4, 10 W white LEDs is illustrated as a design example. Table 1 shows the circuit specifications and are obtained by using the below equations.

The input voltage is 25 V. The forward voltage drop for 1 LED is 12 V. Hence, the output voltage for 4 LEDs is 48 V. From output power and output voltage, the output current can be calculated.

The equivalent LED resistance can be obtained from output voltage and output current. Table 2 gives the circuit parameters.

Buck- Boost ConverterThe frequency of the line-voltage source fL is much lower

than the high switching frequency fs of S1 and S2. The rectified input voltage vrec is a constant over a high-frequency cycle. In the operation from Mode I to Mode III, either S2 or DS2 is on, the rectified voltage vrec supplies energy to raise the current ip1. Since the buck-boost converter is operated at DCM, ip1raises from zero at the beginning of Mode I and reaches a peak value at the end of Mode III.

The input voltage is given by,

(1)The input current can be calculated by integrating the

current irec over one cycle. It is given by,

(2)From the above two equations, it is clear that input currentis a sinusoidal waveform and it is in phase with input

voltage. Hence a HPF is achieved. The input power is calculated and by integrating the instantaneous value of power which is the product of input voltage and input current over one line cycle.

The input power is given as:

(3)The output power is given by (4)

With a 92% efficiency, the value of Lp1 can be obtained. The value of Lp2 and Lp1 are equal.

Buck ConverterThe on time of the buck converter is the interval from the

beginning of operation Mode IV to the end of Mode VI. During this interval, either S1 or DS1 is on. Hence, the duty ratio of the buck converter is also 0.5. The buck converter can designed to operate at either CCM or DCM. If it is designed to operate at CCM, the inductance Lb needs to be large. The higher the Lb value, the lower the ripple current of inductor

current ib. If the buck converter is designed to operate at DCM, ib rises from zero and will reach a peak value at the end of operation Mode VI. At steady-state operation, the average value of ib is equal to LED current. For fulfilling DCM operation, Vdc should be less than or equal to 2Vo. The buck inductor Lb can be designed by using the equation:

(5)

By diverting the current in one active switch to the anti-parallel diode of the other one is what enables the active switches to achieve ZVS operation. By this way, the anti-parallel diode conducts current prior to the transistor in each MOSFET. The voltage across the transistor is maintained at about -0.7 V when its anti-parallel is on. This small voltage is negligible and the transistor can be turned ON at zero voltage. It means that the turn-on switching loss is effectively eliminated.

Simulation And ResultsThis section deals with the simulink model of the topology,

simulation waveforms and results of the LED driver topology.The Simulink model is shown in Fig. 7. AC voltage of 25

V is applied to the input. The model consists of a diode bridge rectifier formed of 4 diodes which converts the input AC voltage to DC. The input low pass filter is formed by the filter inductor Lm and filter capacitor Cm. The input and output waveforms are obtained by using a scope. There are three MOSFET switches and their gate pulses are obtained with help of a pulse generator except for third switch. Automatic lighting control is achieved by using a LDR. In simulation the adjusted output voltage is scaled to a small value by using a factor 20. And the corresponding gate pulses are given to switch 3.

Voltage across the switches and diodes and current through them are obtained. D5 is the blocking diode, Lp1 and Lp2 are the buck- boost inductors, Cdc, is the DC link capacitor, Lb is the buck inductor and Co, is the buck capacitor.

Fig. 8 shows the input voltage and current waveforms. From the figure the input voltage is 25 V. The input voltage and input current are inphase. Magnitude of input current is less than 1A. Current and voltage waveforms for the switch S1 and S2 are shown in the Fig. 9 and Fig. 10. Gating pulses for the switches S1 and S2 are shown in Fig. 11. The gate pulses shows that switches are operated complementary. Duty cycle is 46% and it is same for both the two switches and the switching frequency is 50 kHz. A short dead time is provided. The voltage across the capacitor Cdc is given in Fig. 12. According to design criteria its magnitude should be less than 2Vo and greater than Vo. Here the magnitude is 58 V.

Gating pulses for switch S3 is shown in Fig. 13. Dimming is done in the output by using the switch S3 and dimming can be controlled with respect to the intensity of light in the room. Voltage corresponding to the light intensity in room is scaled by using a factor 20. The output voltage and current waveforms for 20% dimming is shown in Fig. 14. The output voltage and current contains less ripples.

The input to the prototype is 25 V AC and is connected to the mains through a single phase auto transformer. A single phase step down transformer of rating 230/ 9 V is used for giving supply to the control circuits. The transformer has 4 isolated secondary windings and they are connected to 4 rectifier units. There are three switches in the topology. Two of them (S1 and S2) are complementary switches.

The digital signal controller dsPIC30F2010 is used for controlling these switches. Gating pulses are generated according to the program written in MPLAB. Working voltage of dsPIC is only 3 V and it is insufficient for driving the switches. Hence an optically isolated gate driver TLP250 is used for this purpose. Three gate driver ICs are required for three active switches. A voltage regulator LM317 is used to drive dsPIC which reduces the 12 V to 3 V. The 4 secondary windings of single phase transformer are connected to three gate driver IC's and to LM317. The input voltage and current waveforms are given in Fig. 17 and 18 respectively. Gate pulses for the two switches are shown in Fig. 19.

Voltage across the switches 1 and 2 are given in Fig 20 and 21 respectively. The light intensity at the output is varied with the help of a LDR. Therefore, the experiment is conducted in absence and presence of day light. Pulses for switch S3 with 91% is shown in Fig. 22.

In a dark room brightness of the LED array is more and is shown in Fig. 23. Output voltage in the day light is given in Fig. 24. Comparing these experimental results with the theoretical waveforms, we can see the shape of all the waveforms are identical to the theoretical waveforms.

ConclusionThis is a novel two stage LED driver. It consists of a buck-

boost converter and a buck converter. The buck-boost converter which serves as a PFC converter is operated at DCM to achieve a high power factor and low current THD. The buck converter steps down the DC-link voltage to drive high power white LEDs. The circuit operation is described, and design equations are derived. For achieving the design goals of high power factor and ZVS operation, the output voltage cannot be lower than the amplitude of input voltage.

Both active switches can achieve ZVS. Automatic dimming operation is achieved by controlling the duty ratio of the active switch S3 with the help of a LDR. A prototype of 48 V, 40 W is tested and simulation results are obtained by using MATLAB. THD is 22%.

For getting better results, the controller can be changed to PID controller. The dsPIC control can be replaced by fuzzy logic or FPGA according to the needs and improvement in the circuit. Based on the application, the LED array can be arranged in different manner. For indoor lighting applications only a few numbers of LEDs are required. The same topology can be used for outdoor lighting with more number of high power LEDs.

RTlight+building 2016

The world’s leading trade fair for lighting and building services technology will be held at Frankfurt am Main from 13 to 18th March 2016…

The latest technology is vital when it comes to achieving an improved quality of life at home and work. Integrated building planning, digitalisation, increased interlinkage and pan-system solutions are the key to a

modern and flexible environment at work not only in public buildings, hotels, hospitals, etc., but also at home. Light + Building will present the latest developments and technologies in the field of lighting and building-services technology, a component part of modern life.

Smart system solutions and modern design provide the foundation for an improved quality of life, as well as make it possible to take account of widely differing individual needs. Accordingly, the world’s leading trade fair for lighting and building-services technology will be held under the motto, ‘Where modern spaces come to life: digital – individual – networked’, with the industry showing solutions and technologies that increase the economic efficiency of a building and make life easier for the user.

The top themes at Light + Building 2016 will be ‘Smart technologies: the keystones of modern building-services technology’ and ‘Bright spots in the future: design and function in harmony’. They reflect perfectly the main themes of digitalisation, intelligent building networks, safety and security technology, trends in the lighting market and the impact of light on humans.

Smart technologies: the keystones of modern building-services technology

This top theme combines a variety of aspects, and Light + Building puts the spotlight on the subjects of the smart home, the smart powered building, safety and security technology and Building Information Modelling (BIM).

In the smart home, smartphones and easy installation play a leading role, a fact that is thematised by exhibitors and in the complementary programme of events at Light + Building. The umbrella term Smart Powered Building covers the subjects of energy management and sustainability, as well

as the latest developments in the field of intelligent building networks.

At Light + Building, visitors will be able to see solutions for new buildings and planning new buildings, as well as for retrofitting and modernisation.

Safety and security technology is one of the main themes at the coming Light + Building. Building safety and security is a vital aspect of smart building-services technology for both dwellings and commercial premises – with video monitoring, fire and burglar alarms, access control systems, blinds and exterior lighting. Light + Building shows the latest technologies and trends in the field of safety and security technology, and how they can be linked and / or integrated into smart buildings.

Building Information Modelling (BIM), the digital planning method in the building industry, will continue to grow in significance. Light + Building shows how BIM accompanies the life cycle of a building and the advantages it offers for planners, architects, artisans, companies and facilities managers.

Bright spots in the future: design and function in harmony

Modern design, new materials and the creative use of forms come together with future-oriented lighting technology: the latest design trends in the luminaire market will be shown by national and international exhibitors at Light + Building 2016. The digitalisation of light has paved the way for a new dimension in lighting design. Light is combined with the room, sets accents and becomes an independent design feature. Lamps and luminaires are smaller and more efficient. They fit discretely into the architecture or emphasise it.

Depending on the activity or room situation, there are many different kinds of light available today, e.g., direct / indirect luminaires with variable light distribution for illuminating the ceiling pleasantly or for non-glare workplace lighting. When it comes to decorative luminaires for the private and commercial spheres, tomorrow’s trends are characterised by versatility and individuality.

Innovations in the field of lighting technology focus on people and their needs. The subject of People and health – human centric lighting plays an important role in the lighting market and, of course at Light + Building. Human centric lighting influences more than just people’s vision. It helps improve the performance of young people, makes people of all ages feel better and promotes the healing process. Thus, it is an important, future-oriented subject for the sector and beyond.

Light + Building 2016 will offer a wealth of information about the latest trends. Over the six days of the fair, the approx. 2,500 exhibitors will present all trends from the sector, which will be illuminated in the multifarious complementary programmes and explored in depth in expert lectures. Additionally, the leading international trade fair will offer a clear overall picture. It is split into three main sections – lighting, electrical engineering and home and building automation – with national and international exhibitors presenting their products and services in 22 exhibition halls: a perfect blend that enables trade visitors to amass comprehensive information about subjects of topical interest and to keep their finger on the pulse of the age.
