3. INTRODUCTION
There are many different LED modules and LED light engines (LLE) available on the market,
usually comprised of LED light sources, engines and drivers. In most cases, further compo-
nents must be added to assure their correct functionality.
The first of those is a heatsink. As LED light sources and modules with high lumen outputs
are sensitive to thermal conditions, heatsinks are an intrinsic part of the development pro-
cess for most luminaires. However, what really marks the difference between luminaires
is their ability to provide a desired LIDC. With standard LED modules and engines, the
optical aspects of the luminaires design must be solved through the addition of reflectors,
refractors or lenses.
Herein lies the key to what makes Infinitas unique: it is ready to use without the need for
further development. Infinitas is a 3in1 LED unit that combines high-performance LED
light sources with carefree thermal management and an original hybrid optical system.
This makes Infinitas an ideal choice for both luminaire manufacturers and those seeking
the devices necessary to create a bespoke lighting solution.

KEY FEATURES

5. INFINITAS STRUCTURE
• Aluminium mounting plate that acts as
a heatsink for the module
• Thermal interface material
• FR4 PCB with flexible lumen output
according to used drive current
• Two installation screws make it easy to install
the module in a wide array of settings
• Cover pad

6. The mechanical design of Infinitas is tailored to the idea of easy in-
stallation. Whether mounting into a luminaire, a shelf, or directly into
a ceiling, all you need to do is attach the module using two M4 screws.
To achieve a smooth opening, we recommend laser cutting or the use
of an additional frame placed within the opening to ensure a good
finish.

OPTICAL DESIGN
PERFORMANCE
The Infinitas optical system consists of primary and secondary optical parts. The primary
part is a 2D and 3D geometric structured diffuser that modifies the light distribution of
the light source. The secondary optical part is a reflector, which directs the light in the
specified shape.
Thanks to the combination of these two optical parts, Infinitas offers a LIDC suitable for
use in offices in accordance with associated standards. This is possible as Infinitas has
a very low glare rating, with less than 16 possible in situ and an average illuminance of the
light emitting surface of Lavg 1500 cd/m2
.
Manufacturers and lighting designers can choose between and combine different types
and numbers of Infinitas units in order to achieve a desired LIDC, which can be further
refined by setting of the drive current for each unit.
Alternatives of optic materials
Alternative to standard microprism are different optical refractors / diffusers which
allows to achieve various light distribution curves and due to the diverse transmis-
sion also slightly different lm output. Available on request.

9. TC POINT
The TC point is the location on the Infinitas PCB
where the hottest LED in found. This can be
ascertained using a thermal imaging camera.
Mount a type K thermocouple on the closest
point to the thermal pad – cathode. Make sure
that the thermocouple is fixed in direct contact
with the Tc point. The maximum permissible
temperature at the Tc point must be checked
under worst-case operational conditions and in
a thermally stable state.
TP POINT
The TP point refers the temperature at the Tc
point related to the performance of the LED.
The TP point is located on the top side of the
PCB.
EXPECTED LIFETIME RELIABILITY
The Infinitas module is designed to operate
without an additional heatsink in ambient tem-
peratures of up to 45 °C. The expected life-
time of the unit when used in compliance with
the defined operating condition parameters is
50,000 hours / L80 B10 and 130,000 hours /
L70 B50.
