Better Visibility with Less Energy

Introduction

“Better visibility with less energy”

Lemnis lighting Asia has developed a pioneering concept for the

illumination of outdoor and public spaces. With sustainable LEDs we

create light which perfectly matches the sensitivity of the human eye in

evening and night-time vision. This way much less energy is needed

than for conventional lamps, while at the same time better visibility is

provided. Lemnis is known for its innovative products. We integrate

knowledge of visual perception with the newest LED and lighting

technologies − a Dutch discovery which has brought about a

breakthrough in sustainable public lighting.

Our lighting systems offer a considerable contribution to sustainability,

energy conservation and the reduction of CO2 emissions.

Concept

We combine knowledge of visual perception with the newest LED and lighting

technologies. The light sources in Lemnis luminaires are red, green and blue

LEDs. With this RGB concept, an optimal light spectrum is developed so that

excellent vision is obtained with little energy.

At the relatively low light levels provided by public lighting of up to 10 lux

(about 0.6 cd/m2), our eyes are primarily sensitive to green and blue light.

This can be noticed, for instance, from the fact that people can still see by

the bluish shine of the moon. For this reason, Lemnis lights contain relatively

much green and blue. Red is added for improved colour perception.

In this way we have developed four light colours, each one optimal for its

own application. The basic principle is a high S/P ratio for maximum energy

savings resulting in lighting with high *Enhanced Visual Efficiency (EVE).

S/P Ratio

The S/P ratio is a characteristic of a spectrum and is defined as the ratio

between night vision (scotopic) and daytime vision (photopic). Public lighting

with a high S/P ratio requires less energy to obtain the same level of visibility.

This way energy can be conserved. More visibility with less energy.

Enhanced Visual Efficiency (EVE) is based on IES recommendation TM 24-13 which is calculated as follows: Photopic lumen x S/P Ratio^0.8

Sustainable

Long lifetime

The luminaires have a long lifetime and require little energy and maintenance.

Maintenance is limited to cleaning, because replacement of the light sources is

not necessary. The light sources are pure LEDs, without a layer of phosphorous,

and therefore have a higher efficiency and longer lifetime. LEDs, electronics

and luminaires are designed and selected such that a lifespan of at least 80,000

hours is obtained.

No harmful materials

Lemnis works according to the RoHS guidelines. The materials that are used

last a long time and impact nature as little as possible. Materials that are

harmful to nature are not used in our products.

As part of the design and production process, Lemnis conducts ‘life cycle

analyses’ of its products in order to determine their impact on the environment

and to keep this as low as possible.

Total Cost of Ownership (TCO) and return on investment

Lemnis gladly provides a Total Cost of Ownership calculation for its customers.

This is a complete method for calculating costs, which takes into account not

only the purchase but also lifetime, energy consumption and maintenance.

Experience shows that an investment in Lemnis LED lighting typically earns

itself back in a period of 2 to 5 years.

Sustainable

Videre Videnda

"Videre Videnda" (Latin) means "See what should be seen"

Lemnis has developed a lighting product unlike no other. Using the least energy

possible, the luminaire emits the highest quality mesopic light, with an S/P

ratio of up to 3.4 and a specially tuned spectral power distribution light source.

See what should be seen! Lemnis Street Lights generate bright and clear vision

and brings out an amazing palette of colours of all things in sight!

Practical designs

The light source compartment is easily accessible. This is also the case for the

driver compartment, which is amply dimensioned and offers sufficient space for

optional dimming and control equipment.

By using an ‘anti-fouling’ powder coating, dirt build-up is prevented as much as

possible. The IP66 value of the luminaire indicates that dust and moisture cannot

reach the components.

Innovative Products

The luminaire can be adjusted up and down 5-

degrees and is made easy by the cogged coupling

with the mast piece.

Driver compartment

The driver compartment is easy to open. A rubber

gasket keeps moisture and dust from entering the

compartment.

The dimmable MeanWell® driver is IP65, cast in

resin and SELV–Galvanically separated. The driver is

exchangeable. There also is enough space to add a

dimmer.

Light source compartment

Because LEDs are highly sensitive to dust and

moisture, the light source compartment (the part

containing the optics and the light sources) is

completely dust- and moisture-free. There is no

open connection between the driver compartment

and the light source compartment. If the driver

compartment is opened, for instance in order to

place a dimmer, the LEDs are not exposed to dust

or moisture.

Unique LED light sources

The light sources are pure LEDs with no fluorescence layer. They therefore have a

high efficiency and long lifetime. Temperature management is also important for

the lifetime of LED lights. The LED light sources are in direct contact with the

entire luminaire. This way the LEDs are optimally cooled and a long lifetime is

guaranteed.

Constant Lumen Output CLO

The MeanWell® driver has a standard CLO. This driver ensures that the LEDs

always receive the same quality of electricity, regardless of the delivered voltage

and possible ageing of the LEDs. This way, the light sources provide the same

amount of light during their entire life span.

Standard colour is RAL 7035 (grey). All colours are possible depending on specified mininum

order quantities and availability.

Standard colour: RAL 7035 (grey)

Dimming (optional)

Dimming is an interesting option for achieving additional energy savings.

Lemnis luminaires are designed to be able to integrate this option. The driver

in the Lemnis luminaires (Meanwell®) comes with a standard 1-10V control.

The dimmer is adjusted to this so that it dims the installation perfectly and

obtains the desired energy savings.

Lemnis can deliver luminaires with a pre-programmed dimming regime. The

customer indicates which regime he or she desires, and Lemnis ensures that

this is realised.

Re-use of Lamp PostMore savings: keep existing lamp posts

The luminaire is a retrofit product that fits all lamp-posts, eliminating the need to

replace existing lamp-posts. Also, there is no need to increase the number of

lamp-posts as the luminaire is designed for wide and uniform lateral light throw.

This is not only simple and convenient but also fits with our goal of sustainability

and the re-use of materials.
