LG Chem OLED Light panels havebeen used as the main lightsource at Tincan, a newly

opened pop-up restaurantdesigned by AL_A. The restaurantwhich was introduced in time forthis year’s London Design Festival,serves an exquisite collection oftinned seafood along with carefullyselected beer and wine. Thedecision to use LG Chem OLEDs forthe restaurant’s lighting was basedon the excellent light quality as wellas the design possibilities unique toOLEDs. Moreover, the simplicity ofOLEDs enabled the architecturaldesign firm, AL_A, to design andmanufacture the lightings them-selves.“It is very easy for us to be creativeand think of new designs. It is a‘simply plug-and-play’ element. Itopens a whole new world ofpossibilities” says MaximilianoArrocet, a director at AL_A. Theactual lamp was prototyped using3D printing. Although the finalproducts were created throughaluminum spin forming, thedesigners at AL_A admit that the 3Dprinted version could have wellbeen the final product.

LE: How DALI professionallyenables easy and intelligentmanagement of lightingEquipment?

DALI: The DALI protocol is aworldwide standard for lightingcontrol. It provides lighting controlspecific requirements that are notfound in other protocols, andincludes standardisation of controlgear for all common lamp types.DALI allows a choice of individual,grouped or broadcast communica-tion, providing control, configurationand feedback to/from lightingdevices. Flexibility in system designis built-in, allowing very simplesystems using broadcast levelswithout any configuration, tosystems that make use of the fullyautomated DALI emergency lightingtesting and reporting. Regardless ofwhether the system operation issimple or rich in functionality, therequirement is the same commonlyavailable 2-core 1.5mm2 bus cable,which is used for communicationsas well as supplying bus-powereddevices.

Wireless can also be used in a DALIsystem– for example by using aninterface (gateway) between thewireless devices such as buttonsand sensors, and the DALI network.This can provide the convenience ofwireless together with the reliabilityand low cost of wired connectionsto luminaires. Interfaces to manyprotocols are available, and moreare still being added. Examplesinclude TCP/ IP, BACnet and KNX.

LE: What part of the DALI is?Especially for the GermanElectrical and ElectronicalManufacturers Association? Orits for the Worldwide membersfrom the lighting industry?

DALI: DALI is a global standard. Dueto the growth of LED, the increasingdemand for energy saving andgrowing awareness of lightingcontrol systems, DALI has becomeworld-wide more important thanever before. Today, with almost 130international members, DALI is aglobal standard for professionaldigital lighting. Our focus was andwill always remain international.

LE: How big is the lamp andluminaire control market inGermany, and there presence inthe International market?

DALI: Pertaining to Germany, thelamp and luminaire control market istraditionally a very strong market witha high and well-recognised positionin the international market itself. Butnevertheless this reputation, in 2013the German lamp and luminairecontrol market had to deal with adecreasing trend. While domesticsales stay on the previous year level,

export sales are currently influencedby a weak economy situation.On the contrary, the DALI protocolitself shows a growing, worldwidesuccess. This is a result of theblurred borderline between sale ofsingle luminaires and the increasingsales number of electronic controlsystems, such as DALI. In the recentyears the DALI protocol sharedrepresented approximately 50% outof all dimmable LED & fluorescentcontrol gear. This shows that theDALI protocol is not only becomingthe true standard for professionallighting in Europe. Also internationalregions recognise and show theirinterest in the DALI technology.

LE: Lighting Control systemswhich we believe to be veryimportant in the field of energysaving and growing awarenessof lighting control, how DALIcan help local manufacturersfor this?

DALI: DALI was developed as aninternational industry standard forintelligent and easy management oflighting equipment. The standardincorporates several parts thatprovide control and monitoringfunctionality for ballasts, emergencygear and LED gear, expanding tolighting controls in the near future.Compared to a fixed outputinstallation, the dimming andindividual control capabilityprovided by DALI enables consider-able energy savings. In combinationwith dimmable drivers, presenceand daylight sensors, energy savingsof up to 80 per cent can beachieved. If the operation of thelighting is to be rearranged orregrouped, the costs per circuit in afixed output system could be four

times higher than those in a DALIsystem. The ability to send queriesand obtain replies – two-waycommunication – can greatly reducemaintenance costs. For example,DALI allows automatic testing andreporting of monthly function testsof emergency lighting. In addition,energy consumption and lampcondition can be checked for eachluminaire, very easily and at noadditional cost.

LE: What sort of membershipare you the membership? Isthere any fee involved?

DALI: The membership in the DALIworking party of ZVEI is open forCompanies, if and when theypertain to the electrical or electronicindustry and pursue an activity in thelighting industry. Organizations mayalso qualify for membership in theWorking Party, if and when theypursue an activity in the field of theWorking Party. Currently the annualmembership fee is 5000€.

The membership fee covers notonly the right to use the DALI logoon compliant-tested products.According to that, the DALImembership offers a broad range ofbenefits for its members. Forexample, the contribution in theTechnical Working Group allows toevolve the standard for DALI andhelp to support the developmentand to ensure the interoperability ofthe standard.

Also participation and contributionin the DALI Marketing Working Groupallows to evolve marketing strategiesand help to promote the DALIstandard as the de-facto lightingmanagement system.

Kevin McCann is Chair of the DALI Marketing Group and represents the DALI member Mackwell. Taking the role asDALI Chair of Marketing Working Group he promotes DALI as the true standard for professional digital lighting to theindustry and beyond. Mackwell itself is a leading global manufacturer of innovative technology solutions for thelighting industry. Light Express spoke with Kevin about DALI’s role in Lighting Industry.

APANET Green System Ltd is aproducer of Smart LightingControl System devices

based on LonWorks® technology,compatible with most of the SmartStreetLight systems in the world. TheGLC Controller won an award „BestProduct – category control systems”of Light Fair 2011 and 2013. The GLCwas nominated for the Gold Medalof Poznan International Fair 2011. TheSmart Lighting Control System won aprize of the Department of theEnvironment in GreenEvo GreenTechnology Accelerator's contest.The company was nominated inSustainable Energy Competitionpatronaged by European Commis-sion for Energy in Brussels in 2012.The Smart Lighting Control System isalso a laureate in Teraz Polska(Poland Now) Polish PromotionalEmblem Foundation contest. In2014 APANET Green System Ltdbecame an official member ofLonMark® International.

What is a GLC?

GLC – Green Light Controller is asmart driver controlling lamps in thestreets, parks, squares etc. It enablesfull control over the lightinginstallation:

individual street lamps control;manual or automatic on/off

powering as well as lamp powercontrol,

lamp clustering according tospecific requirements as well assetting various control algorithms forvarious lamp groups; when thesame installation is used to powerboth estate streets and busier roadsthere are different energy savingoptions set to ensure the roads arelit according to standards andregulations,

calculating electricity consump-tion for individual lamps, clusters oflamps or additional equipmentpowered by the same powersource, e.g. christmas lights,

street lamps operation monitor-ing; in the event of malfunction thesystem can notify an operator orservice teams of the need forintervention e.g. by sending a textmessage,

detection of an unauthorizedlamp housing opening includingnotification of appropriate services.

How does a GLC system work?

System Green Light reduces lightingparameters whenever possible. Forexample, if traffic is low, e.g. late atnight and the weather conditions are

good, there is no need for a lightingsystem to operate at full power. Thesystem is able to reduce lightingparameters or completely switch offsome of the lamps (even thoughswitching off some lamps is contraryto the principle of maintaining streetlighting continuity, it is allowed incertain cases).

Such systems allow a significantreduction in electricity consumptionand therefore contribute tosubstantial savings – the currentinstallation in Oslo confirms savingsof up to 70%. A very importantfactor in using such systems is thatthey can be easily implementedwithin the existing lighting installa-tions.

The system allows calculating energyconsumption for several customers,e.g. less operators responsible forlighting an area powered by thesame installation, offering access tothe control system independentlyfor each of the customers.

Technology

The GLC system operates usingEchelon's LonWorks technology.

Smart Lighting Control Systems by APANET

Utilising an open communicationstandard allows using equipmentfrom various manufacturers. There isno need to get attached to only onemanufacturer which allows choosingthe best solution available on themarket when implementingsubsequent investments – there isno risk that new system elementswon't communicate with the oldones.

Communication between SmartLighting modules uses cablespowering street lamps (LonWorksPower Line Communication, in shortPLC) therefore installation does notrequire additional workloadassociated with laying cables toconnect individual lamps.

In many cases this would be difficultand would involve planning andconstruction works and very oftencould even prove impossible.

Ever since governmentregulations began phasing outthe traditional light bulb in

2012, the once-simple visit to thelighting aisle has become anexercise in navigating a dizzying arrayof choices and terminologies,especially for new kinds of compactfluorescents and LEDs.

Now, those choices are about tobecome even more complicated.Two start-up companies are poisedto begin selling bulbs that useentirely different technologies —one borrowed from heavy industryand the other from old-fashionedtelevisions — but meet the newenergy standards.

Whether they can capture custom-ers who remain stubbornly weddedto incandescent light is anybody’sguess. But that both have come thisfar is an indication of how unsettledthe consumer lighting marketremains, despite years of promotionfor the new energy-saving options.

Philips sells a range of energy-enhancing lights, including thegoLITE BLU, a panel of blueLEDs.Gadgetwise: LEDs ChangeThinking About the Light BulbFEB. 5,2014

“It’s going to be a really long putt totry to replace the incandescent,”said Mark Rea, director of theLighting Research Center atRensselaer Polytechnic Institute.“People hate change of any kind. Wemake light sources today that arebetter than incandescent by anymetric at delivering the benefitsyou’re expecting from lighting. Butit’s different.”

Indeed, incandescent bulbs —

whether leftover store inventory ofstandard lights or halogen modelsthat meet the new regulations,which went fully into effect inJanuary — outsell other types by farat big-box stores like Home Depotand Lowe’s, lighting executives theresay. In the last quarter of 2013,according to statistics from theNational Electrical ManufacturersAssociation, incandescent bulbsaccounted for 65 percent ofshipments from manufacturers, withthe remainder consisting of mainlycompact fluorescents.

Even as government officials,manufacturers and retailers focustheir efforts on improving andmarketing LED technology, research-ers and entrepreneurs have beenpursuing others, convinced thatnone of the options on the marketoffer consumers a close enoughmatch to the familiar light quality at alow enough price. LED bulbs, forexample, offer light quality that manyexperts say is equal to or better thanthe traditional incandescent bulbs,but their price — often $10 a bulbor less after starting out several yearsago at about twice that — hasscared off consumers.

“We have evolved as a speciesunder daylight during the day andthe incandescent light at night in theform of fires and candles and thenoil lamps and finally incandescentlighting,” said KonstantinosPapamichael, co-director of theCalifornia Lighting Technology Centerat the University of California, Davis. “Iwould find it hard for people toenthusiastically move into newtechnologies without gettingsomething similar to what theyhave.”

So at a small demonstration lab here,just outside Boston, a glass artist indark goggles blows speciallydesigned tubes, one tiny compo-nent of a new bulb to be calledFinally when it makes it to storeshelves. A few yards away, ascientist examines multicoloredgraphs representing the spectrum ofcolors the bulb emits. And over in acorner, dozens of the lights glowupside down, part of thecompany’s quality control.

It is all part of the quest of JohnGoscha, who already has onesuccessful start-up company underhis belt, to build a better light bulb.Mr. Goscha, 30, started a customgolf-club business in high schooland founded IdeaPaint, whichallows most surfaces to function asdry-erase boards, as an undergradu-ate at Babson College.

The Finally bulb will be $8, competi-tive with some of the cheapest LEDson the market. Credit Rick Friedmanfor The New York TimesBut IdeaPaint grew up, he said, andabout three years ago he was eagerto do something new.

“I took a couple of months and justtried to kind of open my blindersand say, ‘Hey what’s going on in theworld,' ” he said. Around that time, afriend mentioned the incandescentphaseout, of which he had beenunaware. Unhappy as a consumerwith compact fluorescents andLEDs, he said, he decided to pursuemaking an alternative. “I thought, ‘Idon’t really want those and therehave got to be other people whodon’t want those either,’ ” he said.

Looking for the solution, he beganattending conferences and meetings

and enlisted the advice of VictorRoberts, a former General Electricengineer who eventually joined theventure. On a flight to Hong Kong,the two talked about induction, atechnology that has many applica-tions, including electric motors inhome appliances and constructioncranes because it is long-lasting. Butit had not yet been widely adaptedfor home use in lighting because itwas difficult and expensive to fit theelectronics needed for bright,omnidirectional light inside a regularbulb.

With the advent of smaller transistorsand other advances, though, thecompany, which has hiredengineers from established lightmakers like Osram Sylvania andPhilips, shrank the apparatus to athree-inch antenna wrapped incopper wire. That creates amagnetic field inside the bulb thatprods mercury to produceultraviolet light, which in turn createsvisible light when it interacts with aspecial phosphor coating the glass.

The result, to be manufactured inIndia, has almost all of its regulatoryapprovals. It can be disposed of inlandfills despite its mercury contentbecause the amount of metal isminuscule and in solid, not liquid,form. It also has received approvalfrom the Federal CommunicationsCommission because the antenna istechnically a radio receiver, albeit aweak one. Mr. Goscha plans to sellthe bulb for $8, making it competi-tive with some of the cheapest LEDson the market.

But although it has shown enoughpromise to have attracted about $19million from investors, includingsome of Mr. Goscha’s Babson

professors and interest from big-box retailers, its path is not yetcleared.

Take, for instance, the Vu1, a bulbthat was supposed to come tomarket more than three years ago. Itwas available for a time on theLowe’s website but had productionproblems and was withdrawn. Withnew manufacturing operations inChina rather than the CzechRepublic, said William B. Smith, thecompany’s chief executive, it is onlynow ready to begin shipping tostores.

“This is all self-inflicted self-hatred,”Mr. Smith said jokingly about thecompany’s missteps, whichincluded losing Wall Street backingafter missing too many deadlines.“Whenever you move a technologyfrom one country to another, it nevergoes as planned.” Mr. Smith said hewas largely financing the companyhimself while it struggled to get onbetter footing.

The Vu1, which will be available firstfor use in recessed fixtures, uses atechnology like that of cathode raytubes in televisions, a “state-of-the-art 1940s technology,” Mr. Smithsaid, in which electrons hit a cocktailof phosphors on the glass, whichthen glows.

But the light’s long journey to storesshows how difficult it can be tomake a new light bulb and howelusive the promise of newtechnologies can be.

Researchers, seeing a market that iswide open, are still working on evenmore technologies, includingplasma and so-called organic LEDs,which spread light over a flexiblesurface.

“Twenty years from now, we’ll walkinto a room and OLED is going to becovering your entire ceiling and it’sgoing to dim automatically and it’sgoing to be able to figure out yourmood and it’s great,” Mr. Smith said.“Thanks, Captain Kirk. But we’re notthere.”

White LightColor TuningOffers a NewDimension ofLightingControlBY CRAIG DILOUIE

14 | Hong Kong Interntional Lighting Show 2014 Special | lightexpress

“Light is comprised of wavelengthsthat the human eye interprets ascolors. For an object to beperceived a certain color, that colormust be present both in the lightstriking an object and the objectreflecting the light towards theobserver’s eye. Because of this, thechoice of lamp for white-lightgeneral lighting can influence howcolors are perceived in a space. Thismeans that perception of objects inthe space is, to an extent, control-lable.”

Traditionally, this level of control wasextremely limited. To change theshade of white from warm (about<3000K) to neutral (about 3500K)to cool (about >4000K), we wouldessentially have three choices: 1)change the lamp, 2) add a colorfilter to a luminaire, or 3) separatelycontrol layers of warm and coollamps. These options could beexpensive and offered limitedflexibility.

In contrast, solid-state lighting offersnew possibilities for controllingcolor temperature. This wouldinvolve a master controller to controlthe system, DMX, DALI or otherinterface between the mastercontroller and each LED product,and LED products with separatelydimmable arrays of warm and coolLEDs or separately dimmable colorsmixed with white. Depending on theLED product, it may 1) provideprogrammable and user colortuning, 2) imitate the warm color ofincandescent lamps when dimmed,and/or 3) offer precise colormatching between LED productsand calibrate to maintain constantcolor output over their life.

Focusing on the first option, whyshould we care? The simple answeris the color qualities of a light sourcecan affect the appearance of aspace. In some applications, color iscritical. In a high-end retail applica-tion, good color quality can makeproducts, especially clothing,appear more vibrant, truer andultimately more appealing. In anoffice application, color quality canfacilitate social interaction by

rendering faces more naturally andthereby helping to create a moreproductive and appealing workenvironment. In a healthcareapplication, good color choices canmake guests feel more welcome byimitating the warm lighting condi-tions of home, while rendering skinsmore effective to help detect illness(jaundice, rash, infection, fever,etc.).

The list goes on. Think about theapplication: Do you want it to bevisually warm or visually cool? Theright color temperature is often amatter of psychology—bothpreference and tradition—with dueconsideration for emphasizing (andnot distorting) dominant colors inthe space and properly renderingcolor contrasts that make tasks morevisible or call out safety markings andinstructions.

When making a case for a lightsource, particularly as a retrofitoption for an existing building, it’shighly beneficial to make aneconomic argument that goesbeyond energy and maintenancesavings. If the designer caneffectively connect economicbenefits to various aspects oflighting quality, the owner will bemore amenable to paying more forthese choices because they willperceive a return on investment.Color is one such area. As one smallexample, consider the results of

three German experiments in whichmore than 500 people tasted whiteRiesling wines under different lightingconditions. The researchers used aseries of fluorescent lamps thatproduced red, blue, green or whitelight. People rated the wine’s qualityhigher, in general, when they drank itin a room whose ambient lightingwas red or blue versus green orwhite. They also found the test winemuch sweeter and fruitier whensampled in a room lighted withfluorescent lamps with a warmercolor tone, and were willing tospend more for it.

The problem is the right choice ofcolor temperature is not alwaysclear. The challenge becomes moresignificant in spaces that wouldbenefit from different shades ofwhite (and other colors) dependingon different functions or times ofday or year.

A survey of lighting designers andspecifiers conducted by theNational Lighting Product InformationProgram revealed that for retailapplications, light source colorproperties are considered moreimportant than any other light sourcecriterion, including energy efficiency.Now imagine a light source thatcould be tuned—precisely, exactlywhere you want it—to optimizepresentation of various merchandisedisplays. Color output could changebased on time of day, as merchan-dise displays change, or fashionseason. In change rooms, coloroutput could be manually adjustedby customers to view themselvesunder different lighting conditions.

Inmeeting spaces, color output couldbe manually adjusted to adapt thespace for different functions such asbusiness meetings and socialevents.

Finally, imagine a hospitality spacewhere color and décor are critical;the designer could tune the coloroutput with the owner and otherdesigners to achieve a precisespace appearance after the finalcolors and materials are selectedand the luminaires are installed. Andlater, at any time, to accommodatefuture changes. In a restaurant, coloroutput could be adjusted from coollighting during business luncheonevents to warm lighting for eveningdining.

TSMC Solid State Lighting Ltd.(TSMC SSL) introducedPhosphor-on-Die (PoD)

technology and its applications atthe Frankfurt Light+Building 2014with ambitious plans to fulfill thehigh-end requirements in lightingmarkets. After PoD technology andTR series modules were announcedin 2013, TSMC SSL began a series ofprojects with customers implement-ing this technology to their fixtures.These new applications alsounveiled at Light+Building 2014.

PoD technology applies TSMC SSL’sown flip-chip LED dies andencapsulates them in a phosphorcoating. Its characteristics such aschip scale size, high lumen density,wide 150-degree viewing angle,consistent color temperatures andfeasible high-voltage design allowfixture designers to overcomecurrent LED light source limitationsand fulfill their needs for innovativeand versatile fixtures. At TSMC SSLbooth, visitors will find PoD modules

in point light source fixtures such asPAR and MR16 (T2- & TR-series),light bars and panels (TL-series) aswell as dimmable and CCT tunablefixtures. TR and T2 point light sourcemodules can allow for a small lightemitting surface from PoD’s smallform factor and provide consistentcolor temperature, enabling fixturedesigners to simplify their designsand create excellent light quality: freefrom multi-shadows as well as a highcenter beam candle power (CBCP).

It takes a lot of energy to light upthe world. Lighting is responsiblefor 19% of electricity use

worldwide. In the United Statesalone, lighting accounts for almost25% percent of electricity use inhomes, and about 13% in offices,

stores, schools, and other commer-cial buildings. Clearly, reducing theamount of energy used for lightingwould make us more energyefficient. But modern society relieson electric lights so we can remainactive at all hours of the day andnight. What makes current lightingsystems so inefficient?

The easiest and most obvious stepto save energy is to turn off lightsthat are not in use. While that helps,

it does not solve the problem. Thebig question is, how can we makeartificial lighting more energyefficient?

What We Currently Use

Most electric light fixtures use eitherincandescent or fluorescentlightbulbs, or lamps, as the lightsource. Incandescent lampsproduce a pleasing warm light. Theyare relatively inexpensive to

manufacture and come in all kinds ofshapes and sizes. Many differenttypes of lighting fixtures aredesigned to fit the screw-in base ofthis type of bulb.

The incandescent lamp consists of alarge glass bulb attached to a metalbase that serves as the electricalcontact. The outside of the base isthreaded, to be screwed into thelight fixture. The hollow glass bulbcontains a metal wire called a

filament—the filament is made oftungsten—attached to the electricalcontacts in the base of the bulb.The filament is very long—about 2 m(6.5 ft) in a standard bulb—butextremely thin, at about 0.254 mm(0.01 in). The wire is very tightlycoiled and that coil is then woundagain, to fit inside the bulb. An inertgas such as argon fills the inside ofthe bulb. When an electrical currentruns through the filament, it heats upand glows.

Fluorescent light fixtures have longbeen used in offices, stores, andclassrooms. The light is cool andbright, and does not produce a lotof extra hear.

There are a number of drawbacks toincandescent lamps. The tungstenevaporates over time of use,weakening the filament until itbreaks. At that point the lamp nolonger works and needs to bereplaced. A 100-watt incandescentlamp is rated to last 750 hours, not avery long time. However, the biggestissue for incandescent lamps is that

they are not very energy efficient:they produce heat as well as light.This heat escapes into the surround-ing environment. In fact,incandescents produce the leastlight for the amount of energy usedto power them. This makes themhuge wasters of energy.

The halogen lamp is another type ofincandescent light bulb. Halogenlamps also use a tungsten filament,but a hollow quartz covering(quartz is much harder than glass)filled with halogen gas encloses thefilament. When the filament heats up,the halogen gas reacts with tungstenvapor, redepositing tungsten atomsback on the filament. This enablesthe filament to last much longer, andto be heated to a hotter tempera-ture. Thus a halogen lamp lastslonger than a standard incandescentand gives off light that is brighter andpurer in color. However, halogenlamps get extremely hot, much moreso than standard incandescentlamps. That means that halogenlamps are also energy wasters.Fluorescent lamps, the other

common type of electric lightbulb,are much more efficient thanincandescent lamps. Fluorescentsuse approximately 30% of theenergy of an incandescent bulb toproduce the same amount of light.They are commonly found ininstitutional settings: schools,offices, stores, and public buildings.Lighting fixtures that use fluorescentlamps are cheaper to operate, andthey produce a fair amount of lightfor the money.

Compact Fluorescent Lightbulbs

The compact fluorescent bulb usesthe same process as a traditionalfluorescent tube, but uses a smallerspiral shape and a screw-in basethat allows it to fit into fixtures madefor incandescent bulbs.

The compact fluorescent lightbulb(CFL) is one very popular option forreducing lighting costs. The CFL is afluorescent lamp manufactured to fitthe same fixtures as incandescentbulbs. This type of lamp has beenavailable since the early 1980s but is

only now catching on withconsumers. The big advantage: CFLsuse much less electricity—70% to75% less, according to somesources.

CFLs have the same energy-savingadvantages of standard fluorescentlamps. But only now are these lampsbeing used regularly. Why? The earlyCFLs were terrible. The light theyproduced was dim and dull, with anawful color. On top of that thelamps took a long time to reach fullpower, and even at full power, theyflickered. Today’s CFLs are muchbetter. The color has been softened,the light is no longer dim, and thelamps start up much more quickly.The improvements have resulted ingreater popularity with consumers.In fact, some countries, includingAustralia and Canada, havemandated that consumers switchfrom incandescent lamps to CFLs byspecific dates. Other countries arealso encouraging consumers tomake the switch to save energy.

CFLs are not perfect replacements

lightexpress | Hong Kong Interntional Lighting Show 2014 Special | 33

for incandescent lamps. Manyconsumers do not like the lightthese lamps produce, despite thevast improvements in the last fewyears. And the lamps still take sometime to warm up to full power. Liketheir long-tube predecessors, CFLscontain a very small amount, usually4 to 5 mg (0.00014 to 0.00018 oz),of mercury, a toxin. If the lampbreaks the mercury enters thegeneral environment. A portion ofthat mercury evaporates, but so littleenters the environment thatresearchers believe it poses little orno danger. Proper cleanup anddisposal of the broken lamp takescare of the rest of the mercury.

Light-Emitting Diodes

Another promising approach is theuse of light-emitting diodes (LEDs)for interior lighting. LEDs arecommonly used already for manythings, such as digital clocks and thelights on light-up wristwatches. Butnow these little lights are being usedin lamps, to replace incandescentbulbs for interior lighting.

The LED bulb is the newest type oflower-energy lamp projected toreplace incandescent bulbs. Madefrom durable plastic, an LED bulbuses the movement of energy in asemiconductor material to createlight.

LEDs use a different technology fromincandescent and fluorescentlamps. Instead of relying on afilament that gets used up orelectrodes with a limited number ofstarts, LEDs produce light by themovement of electrons in asemiconductor, a material orcompound that allows some flowof electricity.

Electricity is sent to a diode made ofa semiconducting material, causingthe electrons to increase in energylevel. As the electrons drop backdown to normal levels, they releasephotons, or light energy. The colorof the light depends on the materialused in the diode. A silicon diodeproduces infrared light, but othermaterials produce different colors inthe spectrum. In addition, thesemiconductor material used for thediode must be one that does not

absorb the photons, but releasesthem outward, to produce light. Thelight coming from the diode goesevery which way, but the lamp has aplastic cover, which concentratesthe light. Individual diodes are notbright. Thus they are groupedtogether in lamps, to produce thedesired amount of light for the bulb.

LED lamps have many advantagesover other types of lighting. They aremade of durable plastic, not more-breakable glass. LED lamps do notburn out the same way as lamps thatuse filaments. The diode doesdegrade, producing less light afterthousands of hours of use. But thebulbs are long-lasting, with a lifetimebetween 50,000 and 100,000 hoursuntil the degradation of lightbecomes noticeable. The small sizeof LEDs fits modern electronics.Most important, LEDs are energyefficient. Much more of the energy isused to create light and not wastedheat.

LEDs are not without disadvantages.Until very recently they wereprohibitively expensive, reflectingthe cost of the semiconductormaterial. The material price hasstarted dropping, but the lampsremain significantly more expensivethan traditional lamps. For example,in 2009 a standard incandescentbulb was around US$0.75 per bulb,while a replacement LED bulb wasUS$45. The longer life of the LEDbalances out some of the expense.

The quality of light given off by LEDlamps poses a more significantproblem. The light tends to bediffuse—it does not focus well forspot lighting. Color also remains anissue. LED lamps produce excellentshades of red, green, blue, purple,pink, and a very bright white.Because of this, LEDs are increasinglybeing used for dramatic and colorfulinterior and exterior architecturallighting, including holiday lights.

However, LED technology thus farhas not been able to produce a lightsimilar to daylight. The very harshlight of a white LED makes colorslook odd. Researchers continue towork on developing an LED lampthat can produce a color similar todaylight.

Daylighting

Natural light is a very importantsource of energy-efficient light.Architects and builders are makingmore use of daylight, working withlighting designers to help placewindows and skylights in newhomes or commercial buildings.Modern double-paned windowscan keep the cold out during thewinter, although not as effectively asinsulated walls, and with specialcoatings to reflect light, they canprevent interiors from heating up toomuch during hot summers.

Newer buildings use natural daylightPhoto courtesy of David Joseph/Lawrence Berkeley National Lab–David Joseph/The New York TimesNewer buildings use natural daylightto light interior spaces as a way tosave energy.

Lighting designers help placewindows in locations that will makethe best use of light withoutburdening the building with extraheating or cooling costs.

For example, north-facing windowslet in even light year-round, whilesouth-facing windows maximizelight in winter; neither lets in muchglare. Proper roof overhang andplanting of trees can prevent extraheat coming in during in the summerin windows that receive directsunlight. West- and east-facingwindows are avoided as much aspossible, because they let in lightand heat, as well as glare.

Skylights also let in light without toomuch heat, if positioned andinstalled properly. The skylight musthave a slope that maximizes winterheat and lessens summer heat.Installation must be done carefully,to prevent leaking during rainstorms.

Down the Road

Motion-detector lights have a sensorthat switches on the light whenmovement occurs within thesensing field. When the motionstops, after a certain time the lightswitches off.

Light fixtures with this feature arecommonly used on buildingexteriors, as a way to have light onlywhen it is needed. Installation of thistype of fixture in building interiors forrooms that are not in regular use,such as storage rooms, is one wayto save energy; this type of use is onthe rise.

Researchers are looking at ways tomake lighting even more energyefficient. One technology underdevelopment would channel thelight from the Sun to the interior ofbuildings through “light pipes” thatcontain reflectors.

Another technology uses fiberoptics to bring in light, combiningsolar lighting and standard electriclights. In this project electricity takesover when sunlight decreases to acertain level. These and othertechnologies are all in the earlystages of research.

There are a number of strategiesto improve lighting energyefficiency that can be

implemented alongside a technol-ogy upgrade.

Switch-off behavioursImproving staff switch-off practicesfor lights applies to meeting roomsand bathrooms as well as at nightand over the weekends. Thetechniques and tips provided forbehaviour change all apply tolighting as well as equipment. Forlighting in particular, energymanagers may need to explain tostaff that leaving fluorescent lights ondoes not save energy compared toswitching them off and on moreoften. Other methods like stickers,signs, and appointing people toswitch off at the end of the day canall prevent energy waste.

REDUCE DEMAND FOR ARTIFICIALLIGHT

Also known as ‘daylighting’ there area number of techniques for makinguse of available light rather thanartificial. Techniques includechoosing light colours for internalsurfaces and walls, skylights, shadingdevice control, glare reduction andelectrochromic glazing. Giving moreaccess to daylight has also beenshown to increase productivity.

OPTIMISE EXISTING LIGHTINGSYSTEMS

As well as switch-off behaviours,there are other ways to get the bestuse out of existing lights. Forexample:

Cleaning off dust build-up from

lamps, reflectors and diffuser panels.Installing light switches in individualoffices, rearranging lighting circuitsto align with work areas or to grouplights in daylit areas.

Replacing discharge lights (e.g.ballasted mercury vapour) with lightswith a shorter time to switch on afterpower interruption (compactfluorescent or LED light fittings).Making use of lighting controlsystems where they are installed,that can program lights according totime of day, daylight and occu-pancy.

Creating smaller zones (100m2) sothat one switch controls fewerlights.

DE-LAMPINGDe-lamping means removing lamps

from fittings where the light outputexceeds what is required. If the lightfitting is inefficient, it can beimproved with a reflector.

Many fluorescent light fittings holdtwo tubes so reducing the numberof lamps saves up to 50% in lightingenergy. De-lamping can result insignificant energy savings at very lowcosts and also reduce air condi-tioner cooling loads, reduce lampreplacement costs, and decreasecircuit loading due to lowerelectricity demand.

There are good de-lampingopportunities in toilets, kitchens,offices, corridors, stairwells, meetingrooms (often over-specified forlighting), copying rooms, waitingrooms, store rooms, and nearwindows in buildings not used atnight.

The steps to undertake de-lampingare:

measure existing illumination levels(using a lux meter and building plan)compare illumination levels withminimum recommended standardsand identify over-illuminated areasde-lamp appropriate areas.More detail and data to helpdiagnose when de-lamping isappropriate are included in theCitySwitch Workbook andCitySwitch Lighting Audit Toolkit.

The Commonwealth Government'sEnergy Efficiency Exchange and theNSW Lighting Technology Reportalso have user-friendly guides tolighting. For de-lamping exercises,disposing toxic waste from mercuryvapour and fluorescent tubes canbe avoided by a number ofrecycling schemes.

OLED luminaireOLED panel: soon at the same level as LED

An exciting fair highlight: an OLED facilitating LED-like efficiency in lighting. One of the essential factors supporting the breakthrough of OLED lighting. The newgeneration of the Orbeos OLED panel by OSRAM, with 65 Lumens per Watt has not yet achieved the efficiency of LED chips but is already more efficient thanenergy-saving lamps. However, LEDs when used in luminaires, require optics that reduce glare and direct the light. These factors are at the cost of efficiency,and thus the efficiency advantage is reduced.

To get a taste of OLED applications in general lighting, OSRAM is presenting an OLED luminaire at light+building 2014 designed by Werner Aisslinger, whowas recently declared Designer of the Year 2014 by the magazine "Architektur & Wohnen". The pendant luminaire with a sophisticated appearance isequipped with 16 rectangular OLED panels and is ideal for use in conference rooms and hotel lobbies.

With the development ofLED lamp technology, thelowly light bulb is doing

more than turning on and off. Alamp can be the centerpiece of anenvironment meant to improvehealth, moods and even food.

LEDs can create light in multiplecolors, generate less heat and use afraction of the energy of older typesof bulbs. And LEDs can becontrolled remotely from a PC orsmartphone app, as programmableas a television.

“There’s a tremendous potential forLED lighting to go beyond illumina-tion,” said John Strainic, GeneralElectric’s general manager forconsumer lighting. “We’re askingpeople to think about lighting asmore than just an impulse pur-chase.”

Because of the LED manufacturingprocess, the light that the technol-ogy creates is weighted toward theblue end of the spectrum. That istrue whether the LED is used in alight bulb, a tablet or a televisiondisplay.

That blue light has its advantages:Blue stimulates a photoreceptor inthe eye that reduces melatoninproduction and helps a person stayawake.

Tabu’s Lumen TL800 lamp usesBluetooth connectivity to control thelamp from a smartphone, allowingthe user to change colors, dim thebulb and synchronize lightingeffects to the rhythm of a songplayed on the phone.“You have to start thinking of light asa drug,” said Terry K. McGowan, thedirector of engineering for theAmerican Lighting Association, atrade group.

That is why Lighting Science, an LEDmanufacturer, is now selling Awakeand Alert, an LED lamp that keepspeople pumped up by pumping upthe blue. Conversely, thecompany’s Good Night lightingproduct reduces the blue output,helping people sleep. This summer,Lighting Science will offer its RhythmDownlight, a lamp controlled by asmartphone app that adjusts bluelight based on a user’s sleepschedule.

“The Awake and Alert lamp doesnot look brighter, but our circadiansystem sees it as such,” said RobertSoler, Lighting Science’s director oflighting research. “We always felt thatthere was so much more you cando with light than just increasevision.”

Philips sells its own range of energy-enhancing lights, including its Wake-up Light and — to combat winterblues — the goLITE BLU, a panel ofblue LEDs.

In Europe, Philips is experimentingwith its HealWell system in hospitals.By changing colors based on timeof day, it encourages a patient towake up, feel more relaxed andsleep more easily. At a field study atthe Maastricht University MedicalCenter in the Netherlands, cardiol-ogy patients were found to sleeplonger and experience reduceddepression.

In the United States, Lighting Scienceis working on a similar system, andexpects to offer products by theend of this year. “Unfortunately,many hospitals have removedsolariums, but lots of studies haveshown that they improve recoverytime,” said Mr. Soler of LightingScience.

While the ability to alter an LEDlamp’s color opens up new uses forlight, the fact that LEDs can beremotely controlled significantlychanges their potential.

The Awake and Alert, an LED lampfrom Lighting Science, pumps outblue light, which stimulates aphotoreceptor in the eye thatreduces melatonin production andhelps a person stay awake.

With Osram Sylvania’s ULTRA iQsystem, users can program lamps toturn on when a key is put in thelock. Philips’s Hue system, on theother hand, allows users to createtheir own lighting moods and thensend those instructions to speciallamps via a smartphone app. Thelights can also be programmed torespond to specific events, such asby glowing a prescribed color whenit is time to remove the roast fromthe oven.

But synchronizing lighting to eventsis much more than a parlor trick.Philips has designed lighting systemsthat decrease growing times andincrease yield for greenhousevegetables and flowers, by using alight’s specific hues.

maturation time while reducingenergy costs.

“We find the optimal light recipe forthe grower,” said Udo van Slooten, aPhilips Lighting general manager forhorticulture.

Within the next few years, theworld’s major lighting companiesexpect to expand LEDs’ connectedcapabilities, particularly with sensors.

For example, sensors could tell howmany people are in a room and theirlocation, and direct the properamount of lighting to where it isneeded. Medical patients prone toagitation could be calmed oncefacial recognition technologyidentifies them and changes the hueof an examining room to morecalming tones. When older peopleenter a room, lighting intensity canbe raised to compensate for theirdecreased ability to see.

“Today, lighting is becoming anappliance, like a blender,” said Mr.McGowan of the American LightingAssociation. “I tell people whenthey move, they should take theirLED bulbs with them.”

Modern houses use a lot ofenergy. We heat them,cool them, and light them

inside and out. We use electricalappliances that allow us to cookfaster, watch television and movies,listen to music, or explore the worldby computer. A 2007 reportshowed that houses are the singlelargest user of energy worldwide,accounting for 25% of globaldemand. The United States leads theway, with its large houses, fondnessfor electrical appliances, and

development of subtropical anddesert regions of the country.

There are two main power sourcesfor buildings. Electricity provides thepower for lights, air-conditioning,and appliances, as well as heatingmany homes. Fossil fuels, either oilor natural gas, are often used inhomes to make heat and hot water.In addition, in many locationsaround the world, the power usedto generate electricity comes fromfossil fuels such as coal. Either

directly or indirectly, then, theworld’s housing is consumingincreasing amounts of energyderived from fossil fuels.

As we know, those fuels pumpcarbon dioxide (CO2) and othergreenhouse gases into theatmosphere. Thus buildings,especially houses, make a hugecontribution to pollution and globalwarming. In the United States,residential and commercial buildingsare responsible for 48% of

greenhouse gas emissions. Aroundthe world, buildings account forsomewhat less, about 30%. So,how can we make homes andbuildings more energy efficient?

There are many ways to reduce theamount of energy we use in ourhomes and buildings. We can turnoff appliances and lights that are notin use. We can adjust the thermostatto use less heat in cold weather andless air-conditioning in hot weather.Energy-efficient products, including

Using Less EnergyTHE ENERGY-EFFICIENT BUILDING

42 | Hong Kong Interntional Lighting Show 2014 Special | lightexpress

furnaces, water heaters, refrigeratorsand other appliances, and evenlightbulbs, can replace older, lessefficient models.

These steps help, but the biggerproblem lies in the construction ofbuildings. If a building is notproperly insulated in the exteriorwalls, the roof, and around pipes, itloses heat in cold weather and coolair in warm weather. Inefficientwindows present similar problems.In fact, some estimates say that theworld loses as much as two-thirdsof the energy used for heating andcooling through poor insulation andleaky pipes.

So, how do we build energy-efficient buildings? Can existinghouses and buildings be remodeledor retrofitted to save energy? Forboth, some of the options aresimple and inexpensive. Others arecomplex and cost a lot to do. All,however, will reduce the amount ofenergy used. This cuts down on theamount of CO2 emissions, thuslessening the “carbon footprint” ofeach building or home. Increasedenergy efficiency also saves money,by lowering energy costs. Manycountries offer financial incentivesfor such improvements.

Heating and Cooling the Natural Way

Before the development of modernheating and air-conditioningsystems, people all over the worldlearned how to build and positiontheir houses to take maximumadvantage of heating by the Sun andthe cooling effect of shade andbreezes. This approach, known aspassive heating and cooling, ishaving a resurgence. Many of thesetechniques have been around forages. Today builders are starting tomake use of these passive tech-niques to make homes more energyefficient.

Passive heating makes use of theSun through positioning of thehouse and use of building tech-niques and materials that absorbheat. Cultures as diverse as theancient Greeks and Romans and thePueblo Indians of the United States

knew how to use the Sun to warmtheir buildings this way.

Cooling techniques use shade,breezes, and water to reduce theindoor temperature. Courtyards withfountains were common in thebuildings of many warm countries,and ancient Persians and otherpeoples from the Middle East andnorthern Africa developedstructures to cool their houses. Inhumid tropical regions, buildingshad ventilation that allowed thewarm air to move out with thebreeze.

Current passive techniques use thesame ancient, local materials, suchas stone, adobe, hay bales, andnative wood. Local materialsconsume less energy in theirmanufacture and transportation.There is even a place for productsof the modern world—for example,used tires, which absorb heat, ormodern glass, which can retain heatfrom the Sun.

Single-Family versus MultifamilyDwellings

One way to increase energyefficiency is to minimize the surfacearea of the outside walls of abuilding relative to the amount ofoccupied space. It is these externalwalls, and the roof, through whichheat is lost in winter and cool airescapes in summer.

Multifamily apartment buildings offersome energy savings. There arefewer exterior walls per family, andfloors above and below act asinsulation.

Multifamily houses come in manyshapes and sizes. Large apartmentbuildings have many floors andmultiple apartments on each floor.Smaller buildings may have six floorsor fewer, with a few apartments perfloor. Some buildings have a longrectangular shape, with manyapartments on only two or threefloors. Attached houses haveexterior walls in front and back andcommon walls on either side. Theone thing all these different typeshave in common is an increased

number of interior walls and onlyone roof. That gives these types ofbuildings a lower potential forenergy loss.

In some multifamily buildings, otherfactors may lessen the energysavings. Poorly constructedbuildings may leak energy throughwindows, doors, and other gaps.There is often less control of heatingfor each dwelling, particularly in thelargest buildings. Common areassuch as hallways and lobbies requireelectricity, if not heat. In addition,large buildings need elevators tomove people up and down thedifferent floors.

New Construction

The simplest way to make anenergy-efficient building is to startfresh. New buildings can easilyintegrate passive heating andcooling techniques, materials thatwill help the building lose lessenergy, and energy-efficientproducts most appropriate for theclimate. In addition, new construc-tion can incorporate alternativeenergy-production options, such assolar panels or geothermal heatpumps, to decrease reliance onfossil fuels.

Many countries, states, and citieshave created “green” buildingstandards for new construction.Standards vary depending on thehemisphere, climate, and materialsavailable locally, because differentclimates require different designstrategies and different materials.

Most important, builders need toconsider the interrelationships of allthese elements. This is called the“whole-house approach.”

Energy-efficient buildings may notlook much different from the moretraditionally built houses aroundthem. However, some builders takea more radical approach. There areearth-sheltered houses, as well asones that use materials such as oldautomobile tires or straw bales forwalls.

Renovation

Realistically, most people can’t startnew: We need to work with existinghouses or buildings. There is stillplenty that can be done, though.The starting point is an energy audit.This tells you how much energy abuilding uses, how much energy itloses, and what measures can betaken to make it more energyefficient. The energy audit checks forair leaks from and into the buildingand assesses the adequacy of itsinsulation. Heating and coolingequipment and electrical appliancescan be replaced as well, to increaseenergy efficiency. Some techniquesfrom new construction can also beapplied.

For energy-efficient construction, wecan learn from the past, we can learnfrom nature, and we can use theinnovations of high technology. Let’stake a closer look at passive heatingand cooling methods and how theycan make a building more energyefficient.

If you haven’t noticed the virtualdisappearance of old-schoolincandescent bulbs from retailers’

shelves, there’s good reason.

With the federally mandatedphaseout of traditional incandescentbulbs entering its final stage,manufacturers and retailers havedone well to make the transitionnearly invisible to consumers. As oflast month, companies could nolonger produce or import 40-wattand 60-watt bulbs, following similarrestrictions on 75-watt and 100-watt

bulbs over the last two years.Some retailers still have enough 40sand 60s to last a few months, butyou may struggle finding them amidthe thicket of new lights labeled “40-watt equivalent,” “60-watt equiva-lent” and the like. While those newbulbs will cost more up front, theycan save money in the long termbecause they require less wattage toproduce the same amount of light.

That said, prices on newer bulbs aredropping quickly, even as designand performance improve. So if you

lack the energy or money to pursuea lighting overhaul in your homenow, sit tight. Your patience — orwariness, or laziness — shall berewarded.

“We’re right at the beginning of this,”said Marc Voykovic, national lightbulb merchant for Home Depot.“The technology is changing sorapidly you’ll continue to seeimprovements in bulbs as manufac-turers are able to crack the code.”

Not everyone can wait that long. My

home’s compact fluorescent lights,or CFLs, have grown so old and dimthat I had little choice recently but tojump headlong into the morass ofthe current light bulb market.Thankfully I had help. In addition tocalling Mr. Voykovic, I contactedCecilia Dupire, principal of Cezign,an architectural and design firm, andRussell Leslie, a founder of theLighting Research Center atRensselaer Polytechnic Institute inTroy, N.Y. Lucas Borntreger, anelectrician in Kansas City, Mo., alsoguided me through a fixture

replacement, but more on that later.

My panelists said the biggestchanges in the lighting market havecome in the realm of the light-emitting diode, or LED. A few yearsago, LEDs were billed as the next bigthing, since they are extremelyefficient and durable, to the tune of25,000 hours of expected life.

But the early bulbs came with “youcan’t be serious” price tags (as in$40 for a 60-watt bulb) and gave offlight that was as soft and warm as agranite quarry in January. Oh, andyou couldn’t dim them.

Over the last year, however,manufacturers rolled out dimmableLEDs for less than $10, with light thatoften rivals the old incandescents.

Are they worth it? Probably.

A 60-watt equivalent LED needs only

12 watts of power to produce thesame light as a traditional incandes-cent. It consumes less than one-third as much energy as the lowest-price bulbs now manufactured: so-called halogen incandescents.

According to the American Councilfor an Energy-Efficient Economy,based on conservative estimates,consumers who spend $10 on a60-watt equivalent LED over a 60-watt equivalent halogen incandes-cent will recoup the difference inabout three and a half years, or lessif you live in areas like New York,where utility rates are among thenation’s highest. At $5, you recoupyour costs in less than 18 months.

Continue reading the main story(The Lighting Research Center’swebsite, www.lrc.rpi.edu, has acost calculator to help consumersselect bulb types. Look for the“Lighting Patterns for Homes”

section, and choose the “rooms”category.)

Some LEDs have more recentlybreached that $5 barrier, thanks toincentives from electric utilitiesprovided for bulbs that carry thegovernment’s Energy Star rating. Lastweek in Vermont and Pennsylvania,among other states, retailers carried40-watt LED bulbs for roughly thatprice.

As newer LEDs gain Energy Starcertification this year, $5 couldbecome the new normal for 40-wattand 60-watt bulbs.

The big question is whether you canfind an LED that gives off yourpreferred light. I tried eight different60-watt equivalent LEDs currently onthe market from a range of manufac-turers, and each of them was rated2700 Kelvin. On the “Light Appear-ance” graphic included on the

bulbs’ packaging, this was close tothe “warm” end of the spectrum.

I expected identical light quality, orclose to it, but at least three of thebulbs were noticeably cooler thanthe others. The warmest, to myeyes, was the Cree, which retails forjust under $10. The Philips 11-wattLED bulb, the more expensive of thetwo Philips 60-watt equivalents, alsooffered a pleasing amount ofwarmth. The coolest was the IkeaLedare E26, which sells for $7.Mr. Leslie said part of my issue couldhave been the white background ofthe light, and that one’s reaction to acertain bulb has much to do with itsimmediate surroundings. “If you buyan LED in the 2700 to 3000 Kelvinrange with an Energy Star label froma manufacturer like Philips, Sylvania,G.E. and Cree, you’ll probably havea satisfactory product,” he said.

To avoid buyer’s remorse, my

lightexpress | Hong Kong Interntional Lighting Show 2014 Special | 45

panelists said, ask questions aboutlight quality at the store, check theretailer’s return policies and savereceipts.

Ms. Dupire said LEDs have improvedto the point that they represent 80percent of the lights in her home.That includes traditional bulbs aswell as smaller lights that comple-ment lamps and other fixtures.

“What’s wonderful about LEDs is thatyou can be both playful andfunctional with them,” she said. “Youcan do more imaginative stuff, likeputting them underneath cabinets orinside closets because they don’tcreate as much heat.”

Following her counsel, I tried thebattery-operated G.E. Wireless LEDLight in a closet that inexplicablylacked a socket, and they instantlyturned the most irritating space in myhouse into something functional.

Lamps and old fixtures can also get aplayful upgrade with bulbs like thePhilips Hue ($60, or $200 for a packof three) or the Lumen TL800 ($70),which you control with a mobiledevice. (The Hue works with theiPhone, Androids and Kindles, whilethe Lumen works with iPhones andcertain Android devices. The Huealso includes a BR30 option forrecessed lighting fixtures.)

Each bulb has a dedicated app thatlets you change colors manually oraccording to predeterminedsettings, among other feats. This isespecially useful if you have troublewaking up or falling asleep andwould like ambient colors to helpyou in either regard.

Continue reading the mainstoryContinue reading the mainstoryContinue reading the main storyI liked both bulbs very much, but Ifavored the brightness and versatilityof the Hue. The setup is slightlymore complicated, however, since

you need to plug a base station intoyour wireless router. The Lumenworks with a Bluetooth connection.Outside of LEDs, my panelists said,little has changed in the consumerlight bulb market. Manufacturershave tweaked the efficiency of theirhalogen incandescents to meet thenew federal standards, andmanufacturers say they expect thesebulbs to dominate the market whilethe LEDs edge their way into themainstream.

Manufacturers said CFL technologyhas stagnated, and my panelistsechoed that sentiment. But I foundone exception worth noting. ThePlumen 001 ($30) and the BabyPlumen 001 ($29) feature a coolvariation of the traditional “twisty” CFLdesign. The company also sellssingle bulbs packaged with a sleek,matching hanging fixture for $65.

The light is warm and pleasant by considered installing a set, but theidea of cutting holes in my ceilingand wiring new fixtures was a bit tooambitious. At the same time, I’vebeen on the lookout for an electricalproject a little more challenging thanrewiring a lamp, but preferably in alow-stakes setting.

It boasts square, recessed fixturesthat were installed 40 years ago, andwhich we, in recent years, lit withjunky CFLs. Sometime last year twoof the fixtures simply stoppedworking. It was almost an improve-ment.

I heard about a new LED product,the Pixi FlatLight luminaire, that’sadvertised as an ideal replacementfor such Nixon-era fixtures. The Pixi isless than an inch thick — includingthe (nonreplaceable) light itself —and comes in three sizes. I chosethe 1-foot square size ($70 each),as it is nearly identical to our existingfixtures.

My only remaining task was to figure

out how to install it withoutelectrocuting myself or creating a firehazard in my house. Pixi offers agood how-to video, but it didn’taccount for the wiring configurationin my basement. Rather than call anelectrician for a visit, I tried a newonline service from Google, calledHelpouts, in which contractors andother professionals offer advicethrough video chats.

The professionals are reviewed byGoogle, but as with anyone youmight contract for home-repairservices, would-be customersshould check out the professional’scredentials before going forward.

Mr. Borntreger, for instance, is alicensed master electrician withextensive experience. For $15 he

offers 30 minutes of advice. Aftertwo calls and about an hour ofwork, I installed four fixtures, and didit with the confidence that I hadn’truined the job.

Without Mr. Borntreger I would haveknown to shut off the light circuit atthe breaker, and test the fixture witha voltage meter for good measure.But had I not called on him, I mostlikely would not have looked deeplyenough into the junction box to seean additional set of wires that wereimportant.

My next time out, I’ll have the samerespect for electrical work but muchless worry. Of course, I’ll probablyrely again on Mr. Borntreger, orsomeone like him, as my phone-a-friend.

The agency said that the materials research center in the field of LEDand OLED are within the scope of the agency’s consideration.

Before the formal announcement, the DOE will hold a webinar for whointends to submit application, and will present an overview for the technicalfields which included in the scope of the DOE’s consideration on July 22.The second webinar will be held to review the application process onAugust 15.

Financing application letter of intent must be submitted on or beforeSeptember 2, formal application also will end on October 14. U.S. Depart-ment of Energy is expected to announce the results in January next year,while grants will also begin issuing in February.

In addition, U.S. Department of Energy scheduled the date of the next SolidState Lighting (SSL) market development seminars from November 11 to 132014, and the agency will announce location soon.

UK Department of Energyplans to fund $34.2 millionfor upgrading LED lightingAccording to UK Department of Energy’s power consumption reductionplan, British families may pay millions of pounds to provide free LED lightingfor supermarkets and airports.

British Energy Minister Ed Davey recently announced the implementation of20 million pounds ($ 34.2 million) taxpayer cash tracking program, aim toprovide funding for businesses to upgrade energy efficiency includingreplacing traditional lighting by LED light bulbs, and these funds will be usedfor those who do not advance funds.

Davey said that companies can compete for funds by reverse auction, andcomplete the entire installation through full or part of the subsidies, whichwill help to generate cheaper energy bills.

There are about 300 organizations, including hospitals, airports, supermar-kets, have shown interest in this pilot, the UK Department of Energy andClimate Change (DECC) said.

The purpose of the program is to reduce the national electricity demand,mitigate blackout risk, and avoid building more power plants. If the programsuccessful, it will continue to provide the cash.

Gruzdev Alexey, the representative of Trade Representation of the RussianFederation in the People’s Republic of China, said in Russian and the CIScountries’ Lighting Market Analysis and Channel Strategy Conference that “Inlighting products, China has always been the largest supplier of Russia.”Along with Russian accession to WTO, prohibition of sale incandescentbulb, Winter Olympics in Sochi this year and World Cup in 2018, Russia hasgreat demand on LED lighting. Russia welcomes the strength Chineseenterprises to participate the LED renovation projects for public institutionsof Russia and CIS countries, large industrial and mining enterprises, sportsstadiums and others.

According to Gruzdev Alexey’s introduction, Russian LED industry wasdeveloped rapidly last year, the growth rate is 250%, and LED lightingaccounted for 10% of market share. Data shows that the Russian LED bulbsales in 2013 are 1 billion units, with total sales of 40 billion rubles (about1.11 billion US dollars). As the Russian government introduced a series ofmeasures to promote energy-saving light sources, it is expected that RussiaLED lighting market share will increase to 35% of whole lighting industry in2016.

Last year, Chinese LED products export to Russia and CIS countries is $ 800million, which Russia accounted for 75.74%. China LED products accountedfor more than 40% of Russian market.

“We strongly encourage Chinese advanced enterprises to invest in Russia,there many Chinese enterprises may worry about the problem of investmentenvironment, tax, legal protection and other issues, the Russian governmenthas done a lot of work in the past few years, and have improved greatly incompany registration, investment, banking services, tariffs and otheraspects.” Gruzdev Alexey said.

“In my opinion, the preferential policies offered in Russia are more favorablethan Chinese implementing policies.” Gruzdev Alexey believes that sinceChina began LED very early, so the preferential policies have been canceledin a lot of economic zones, while Russia is now actively promoting thesepolicies.

He said that if set up factories and registered enterprises in Russia, besidesproviding favorable conditions, the Government will allocate some financialsupport, and different regions have different policies. “For example,including at least five years of free land usage, general profit tax is 20%, inorder to encourage Chinese companies to set up factories in Russia, thisratio may be adjusted. Additionally, the local government is also withpositive attitude on simplifying administration, shortening the approvalprocess, reducing approval procedures, etc.”

TEMPLATE OFFICE OF THEFUTURE FOR GREATER COMFORT,PRODUCTIVITY AND BUILDINGEFFICIENCY

Workers able to personalizelighting and temperaturevia smartphone app

Connected LED lighting poweredover Ethernet provides anonymousoccupancy and climate data formore efficient facility management

Royal Philips (NYSE: PHG, AEX:PHIA), the global leader in lighting,announced a breakthroughconnected office lighting systemthat delivers extraordinary value tofacility managers, office workers, andbuilding owners.

The groundbreaking system usesPower-over-Ethernet (PoE) toconnect office lighting fixtures to abuilding’s IT network. The lightingsystem acts as an informationpathway, enabling workers tocontrol and access other buildingservices via their smartphones,allowing them to enjoy greater visualcomfort and productivity.

The office lighting fixtures, whenoutfitted with sensors, are able tocapture anonymous data on roomoccupancy, temperature andhumidity. They connect to the IT

network and interface with otherbuilding systems such as heating,ventilation and IT services. Thisbenefits the facility manager who hasa single system showing real timeand historical views of buildingutilization. For example, he or shecould see that on a Friday afternoona particular floor is not used andadjust the temperature, lighting, andcleaning roster accordingly. Havingan integrated view of a building’soccupancy patterns and energyusage provides for more informeddecision making with unprec-edented levels of energy andoperational efficiency.

Smartphone controlThe Philips system allows officeworkers to control the lighting inopen plan offices as well astemperature in meeting rooms, tosuit their individual preferences. Theirsmartphones will detect theirlocation from overhead lightingfixtures via an app.

“The LED lighting alone is 80% moreefficient than conventional lighting.Personal control of the lighting byemployees actually increasesefficiency as general lighting levelscan be kept lower.’’ said Jeff Cassisfrom Philips Lighting. “The potentialsavings on a building’s operationalcosts will be significant, given thatheating, cooling and lighting

together account for 70% of abuilding’s energy usage.¹” Thefixtures, outfitted with wirelesscommunications devices, form adense indoor positioning grid, likean indoor GPS, that support a rangeof location-based services, such aswayfinding. Through a smartphoneapp, the system could also provideworkers with useful information suchas the nearest empty meeting room.

Delighting building owners andfacility managersFor building owners, the systemoffers new value that goes beyondenergy efficiency and cost savings.Advanced capabilities such asindoor positioning combine withthe intelligent system to enablecomfort, personalization, and safety,increasing the total value of abuilding and making it moreattractive to tenants.

Standards-based PoE-enabledfixtures also deliver significant costsavings on lighting installation. Asthese fixtures receive both data andpower over a single Ethernetconnection, there is no need forexpensive electrical wiring, reducinginstallation costs by up to 50%.

THE PHILIPS SLIMSTYLE LED LAMP

Here’s a bulb you might think about licking rather than lighting. Philips’s cut the weight of its new SlimStyle lamp down to about three ounces byeliminating the heat sink found in most other LED lamps.

The bulb looks unlike any that has come before — more like a lollipop than a lamp. It has the ability to dim and gets only warm to the touch even after a fewhours of illumination, eliminating two shortcomings of LED bulbs. It’s priced under $10 at Home Depot.

This 60-watt equivalent uses 10.5 watts of energy. The actual light-emitting diodes ring the lamp’s circumference, creating light in all directions. In a test, theSlimStyle created a dimmable, warm glow that was virtually indistinguishable in quality to a standard incandescent. The bulb is now available on the HomeDepot website and will be available in its stores in March.

Like other LEDs, the SlimStyle will meet Energy Star requirements and last for 25,000 hours, or about 20 years of average burning. With its lower price andattractive design, this is a lamp that may still be burning for your grandchildren to see.

An LED Bulb Is Both Dimmable andAffordable
