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
THE GREEN LIGHT

3. 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
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 FOR
ILLUMINATING 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 illuminating 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.

Schréder developed lenses.

7. 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 of 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 painted 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 .
INTELLIGENT POWER SUPPLY
Piano 1 and 2 luminaires are equipped with mains power supplies. They have a
90% efficiency and meet SELV (Safety Extra Low Voltage) regulations.
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 is equipped with a temperature sensor that reduces the current
with 70% when the temperature passes the authorised maximum - for example,
when lighting the luminaire during daylight (for maintenance, testing and so on)
under particularly high ambient temperatures.
A 1-10V input allows a dimming system to be incorporated 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 LED) 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 CO /day (according to the European average of 0.46 kg CO /kWh).
2 2
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% . Up to give dimming level can be programmed. 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.

Evolution of the lighting classification Lmed
according to the traffic density (cd/m2
)
M3 1.0 (100%)
M4 0.75 (75%)
M5 0.50 (50%)
This table sets out the CIE recommendations (work of the
TC4-44 technical committee) that allows for the variation of
lighting classification according to traffic density.
This reinforces the appeal of having luminaries fitted with
an adjustable (dimming) system.
MEMPHIS, THE MOBILE REFLECTOMETER
Thanks to the Memphis road surface reflectometer, we can precisely determine
the amount of light for “correct lighting” 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.
The mobile Memphis road surface reflectometer,
developed by Schréder, associated with the
greater flexibility of the LensoFlex®
photometric
engine is the ideal solution for specifically
tailoring the installation of lighting systems.

10. REMOTE MANAGEMENT FOR MAXIMUM CONTROL (OPTIONAL)
The Piano luminaires can also incorporate the OWLET remote management system.
This open-source, bidirectional communication system is based on the principle of radio frequency via the
ZigBee protocol. It offers numerous advantages:
• Total flexibility of light levels and timings
• Real-time feedback on the actual state of the light
• Accurate measurement of energy use
• Adjustment of power level: Virtual Nominal Power
• Autonomous compensation system for flux depreciation over time: Constant Lumen Output
• Independent of the supply network
MOTION DETECTION (OPTIONAL)
A motion and presence detection system can offer a complementary and efficient tool in urban areas for a
more rationalised usage of energy.
