THE GREEN LIGHT

The LED Generation…. For Schréder, it is innovative, intelligent and responsible.

We have developed a complete range of LED luminaires across all our business

sectors: street lighting, urban lighting, tunnel lighting and illuminations.

These products reflect our desire to continue “Right Lighting”, by offering

technological solutions that make this new light source a valid alternative to

traditional sources.

To do so, we have developed concepts that will make LEDs the new instrument of our

ambition - to offer the lighting solutions of tomorrow.

PoWerFUl PHoTomeTrIC eNgINes

Schréder has developed a photometric engine concept to cover every type of urban

lighting application.

LensoFlex®. A photometric engine that builds on the flexibility offered by a selection

of lenses developed by Schréder, with the goal of creating ambiances and meeting

the needs of urban lighting.

eNergY aNd eCologICal FooTPrINT

Our luminaires are designed with an eye towards sustainable development. They can

be characterised by a number of commitments:

• To use energy rationally, via highly effective photometric engines;

• To reach required levels while complying with international standards;

• To maximise energy savings through intensity variation (dimming) and remote

management systems.

Our LED luminaires also offer the following advantages:

• Long LED service life and reduced maintenance costs;

• Recyclable and durable materials, such as glass and aluminium;

• Compliance with our “Green Light” label.

LEDSafe®

relIaBle solUTIoNs

To offer reliable, durable and effective solutions, Schréder has developed two

concepts:

ThermiX®. Optimise heat extraction to maintain 80% of the nominal luminous flux(*)

at 60,000 hours of use up to a maximum ambient temperature of 35°C.

This concept is based on several factors:

• Thermal compartmentalisation between the LEDs and the control gear;

• Direct conduction by minimising the path between the heat source and the outside;

• Optimised design of the external heat exchange surface;

• A temperature sensor to avoid accidental overheating.(*) 70% for certain luminaires

LEDSafe®. To ensure a long service life by preventing dust and water from getting into

the optical compartment, Schréder has implemented the LEDSafe® system. This is

based on the idea of a completely sealed photometric engine. Protected by glass,

the LEDs and lenses do not come into direct contact with the outside environment.

This helps to ensure that performance is preserved over time.

UPgradaBle TeCHNologY

In our latest luminaires we have developed the FutureProof concept. This will allow

on-site replacement of the photometric engine or electronic assembly at the end of an

LED’s service life, and thereby allow users to integrate future innovations.

UNIVersal desIgN

We have been engaging renowned designers to help us better incorporate our

products into their daytime and night time environments.

THe Ideal INsTrUmeNT ForlIgHTINg THe CITY

Piano luminaires are available in two sizes: Piano 1 up to

48 LEDs and Piano 2 up to 96 LEDs.

The design of the LensoFlex® photometric engine and

the flexibility of the photometric distributions makes the

Piano range an ideal instrument for lighting streets, public

places, parks - optimising the creation of ambiances

that are both a source of well-being and safety for those

making use of the city.

Piano luminaires offer excellent photometric solutions

for low-level areas, such as under foliage, and do not

generate intrusive light for people living in apartments.

A bracket at the rear means that streets, side-streets

and large pavements can be lit using the same luminaire

design. The wall bracket allows for the lighting of narrow

streets as well as any poorly lit areas.

leNsoFleX®, a PHoTomeTrIC eNgINe IN THe CITY

Piano luminaires are equipped with the LensoFlex®

photometric system. This system is based upon the

addition principle of photometric distribution.

Each LED associated with a specific lens generates the

complete photometric distribution of the luminaire. It is the

number of LEDs that determines the intensity level of the

light distribution.

Schréder has therefore specifically developed a range

of lenses which together cover a wide spectrum of

photometric solutions for creating ambiances. The

LensoFlex® concept enables LEDs to be placed horizontally.

It is especially suitable for lighting urban spaces where the

well-being and safety of people using the city are essential.

ThermiX®: THermal maNagemeNT

We have developed the ThermiX® concept based on optimising several parameters

that are involved in the thermal management of LEDs:

• The thermal compartmentalisation between LEDs and electronic control gear;

• Direct conduction: the heat escapes via the shortest path from the source to the

exterior;

• The optimised design of the thermal exchange surface with the exterior;

• The LED circuits (PCB) are equipped with a temperature sensor to avoid any

accidental overheating.

The Thermix® concept maintains 80% of the initial luminous flux for a minimum of

60,000 hours, up to a maximum ambient temperature of 35°C.

ledsafe® aNd eXTra-Clear glass

To maximise the reliability of its LED luminaires, Schréder introduced the LEDSafe®

concept. Like Sealsafe® - which is recognised as a bench mark in traditional source

public lighting - LEDSafe® is based on the principle of a completely sealed photometric

engine. This process ensures that the photometric performance is maintained over time

by preventing water and dust from penetrating the optical compartment.

The protector of the Piano luminaire is in extra-clear glass, which optimises the

transmission of luminous flux.

HIgHlY eFFICIeNT PoWer sUPPlY

The Piano luminaires are equipped with power supplies. They ensure 90% efficiency

and fulfil Safety Extra Low Voltage (SELV) requirements.

The supply current is 350 mA to optimise the efficacy of the LEDs and maximise

lifespan.

The power supply also offers an increased protection against power surges.

Each luminaire has a temperature sensor that reduces the power supply by 70% in

the event the temperature exceeds the maximum authorised - for example, when the

network administrator switches on the luminaire during the day (for maintenance,

testing, etc.), with a particularly high ambient temperature.

Input of 1-10V, allows a user to integrate a dimming system to optimise energy used.

FUTUreProoF

Piano luminaires are designed to meet our FutureProof concept. Both the photometric

engine and the electrical power supply can be replaced on-site to take advantage of

any future technological developments.

eNergY CoNsUmPTIoN

Piano luminaires have demonstrated remarkable photometric performance, equipped with flat glass.

For example, for the Piano 1 (32 LEDs) used on a 5m-wide M4 classification road, according to CIE recommendation

No.115, the installed power to handle the required luminance level of 0.75 cd/m2 is less than 0.75 W per m² of road and

per cd/m² required. This also takes into account the depreciation factors for both the LEDs and the luminaire.

For 4000 hours of use per year and for 100m of road, this corresponds to a consumption of less than 3.0 kWh/day, or

emissions of less than 1.4 kg CO2/day (according to the European average of 0.46 kg CO2/kWh).

The flexibility of the LensoFlex® photometric engine allows for multiple light distributions to respond better to the

requirements of urban lighting.

Furthermore, the options for varying the number of LEDs allows for a precise adaptation to the nominal power of the

luminaire according to the area that is to be lit.

On a project by project basis, our teams are on hand to offer you a range of solutions using either LEDs or discharge lamps.

As the specifications for each project become clear, so the right solution emerges, bearing in mind any constraints you may

be working with.

VarIaBle INTeNsITY (dImmINg) For greaTer saVINgs (oPTIoNal)

Piano luminaires can be fitted with an independent dimming system. This is an important way of reducing energy

consumption - capable of saving up to 30%. The programmable levels range from 1-5. The different dimming levels are

handled daily and automatically adapted according to the length of the night.

Contrary to traditional sources, LEDs allow for the variation of intensity at a very low level keeping the same colour

temperature and same colour rendering index without losing light efficiency. The luminous flux is, in effect, reduced in

practically the same proportion as the energy consumption.

memPHIs, THe moBIle reFleCTomeTer

Thanks to the Memphis road surface reflectometer, we can precisely determine the

amount of light for the “right light” based on the type of surface. Memphis allows

for multiple measures, on site, reflecting the characteristics of the road without

damaging it.

By associating Memphis with the LensoFlex® system, we are able to rigorously define

the most optimised photometry.

This combination offers the ideal solution for specifically tailoring a lighting system

and ensures optimum control of the energy consumed.
