PrevaLED ® Cube G3 LED modules | Introduction
1 Introduction
1.1 System overview
Building an LED-based luminaire poses a set of technical
challenges, among them optical requirements, providing
­adequate thermal management for stable operation and
dealing with the improving performance of LEDs. Nevertheless, LED technology also provides an unknown number
of possibilities, opening up unprecedented levels of performance.
OSRAM’s PrevaLED® family of LED light engines addresses
the challenges of LED-based lighting while providing users
with great performance and flexibility at the same time. Enabled by the application of LED technology, PrevaLED® is
aiming to push the envelope of what is possible in terms of
performance and simplicity.
PrevaLED® Cube G3 LED light engines offer one of the best
and easiest ways to outfit luminaires with LED technology.
They are ideally suited for use in highly diffuse wall-mounted
and ceiling-mounted luminaires in decorative, hospitality
or domestic application as well as a broad range of wide-­
reflector-based luminaires such as downlights.
Future-proof concept
To allow for a smooth transition to this new generation of
the PrevaLED® Cube series, crucial features have remained
the same:
—— Complete portfolio in terms of luminous flux, color
temperature and color rendering
—— Same form factor and mechanical/optical interfaces as
previous generation
—— High driver flexibility allows cost-effective and intelligent
systems
—— 5-year guarantee (for current terms and conditions of
the guarantee, please visit www.osram.com/systemguarantee)
—— Selection of dimmable and non-dimmable LED drivers
Of course, important improvements have been realized
as well:

color temperatures: The PrevaLED® Cube G3 series is
available as a 1 100 lm, 2 000 lm, 3 000 lm and soon
5 000 lm package in two light colors (3 000 K and
4 000 K); further light colors (2 700 K and 3 500 K) and
the PrevaLED® Cube G3 board version are available
­upon request through your sales partner
—— Low height of optical contact area (OCA) of 18.6 mm for
compact luminaire design
—— Near Lambertian light distribution for best quality of light
in diffuser as well as reflector-based applications
—— Industry-standard mounting holes and light-emitting
surface (LES) for use with standard heat sink and
­reflector accessories
—— Lifetime (L70B50) at tc = 80 °C: 50 000 hours
—— Improved poke-in connector for stranded and solid
wires
—— Very good light quality
—— Very high efficiencies for smaller heat sinks and easier
thermal management

2.2 Reflector design
The light-emitting surface of the light engines is covered by
a diffuser to ensure a homogenous, smooth light distribution. Please ensure that the temperature of the diffuser
does not exceed 120 °C.
PrevaLED® Cube G3 light engines can also be used with
secondary optics. As their optical interface has the same
dimensions as common downlight modules in the market,
they can be combined with available off-the shelf secondary optics.
OSRAM provides mechanical (3D files) and optical simulation data (ray files) to support customized reflector design.
Ray file data are available upon request through your sales
partner.

3.7 LEDset2 (LT2)
LEDset helps you to meet important market requirements:
—— Future-proof solutions in terms of luminous flux
—— Long-life operation
—— Luminaire customization
—— Energy and cost savings
3.8 ESD
It is not necessary to handle PrevaLED® Cube G3 LED
modules with housing in electrostatic protected areas
­(EPAs). To protect a PrevaLED® Cube G3 LED module from
electrostatic damage, do not open it. The PrevaLED® Cube
G3 board version without housing must be handled in electrostatic protected areas.
LEDset2 (LEDset generation 2) is the enhanced interface
between OPTOTRONIC® LED drivers and LED modules
(such as OSRAM PrevaLED®). It can be identified by the
product name of the LED driver, including the letters “LT2”
at its end.
LEDset2 is based on a three-wire connection between the
LED driver and the LED module. This interface is designed
to allow communication between the LED module and the
LED driver, performing LED current setting and thermal
protection functionality.
Combined with PrevaLED® Cube G3 LED modules, the
­interface supports the following functionalities:
—— Absolute output current setting of the constant-current
LED driver (LED module self-recognition)
—— Thermal protection of the LED module
LEDset2 allows a selection of the output current through
the simple selection of the proper Rset resistor value and the
connection of a potentiometer or a fixed standard resistor
to the LEDset line. The relationship Iout vs. Rset is defined by
the following formula:
Iout [A] =
5 V
x 1000
Rset [Ω]
Note:
More detailed information about the possibilities of LEDset2
interfaces can be found in the corresponding driver application guidelines and at www.osram.com/ledset.

4 Thermal considerations
The proper thermal design of an LED luminaire is critical
for achieving the best performance and ensuring the longest lifetime of all components. Due to the high efficacy
of PrevaLED® Cube G3 light engines, only a partial amount
of the introduced electrical power has to be dissipated
through the back of the light engine. The thermal power
that has to be dissipated for PrevaLED® Cube G3 light
­engines is given below.

­driven with reduced current if higher case temperatures
are desired. In this case, the drive current should not
­exceed 900 mA at 90 °C.

PrevaLED ® Cube G3 LED modules | Thermal considerations
4.3 Thermal protection features
To achieve the best possible lifetime of the LED module
and to save it from damage by overheating, thermal protection features have been integrated. The thermal protection
of the PrevaLED® Cube G3 LED module is divided into two
parts:
The first part of the thermal protection is a thermal derating function that works in combination with LED drivers
with LEDset2 functionality. It protects the LED module from
overheating by communicating with the LED driver (the
LEDset port of the LED module must be connected to the
LED driver). The system reduces the current of the LED
module if critical temperatures are reached. This results in
the best possible performance and lifetime of the LED
module. The characteristic of the thermal derating function
is shown in the graph “Thermal derating with LEDset2”.
The second part is a reversible onboard thermal fuse that
prevents the module from damage by overheating. This
feature does not require LEDset2. If the temperature at the
tc point exceeds the maximum allowed value by approx.
20 °C, the thermal fuse is triggered and the module shuts
off completely. The thermal fuse can be reset by disconnecting the mains and repowering. The characteristic of the
shut-off is shown in the graph “Thermal shut-off without
LEDset2”.

4.4 TIM and other accessories
When mounting a PrevaLED® Cube G3 light engine within
a luminaire, it is recommended to use thermal interface
­material (TIM) between the back of the light engine and the
luminaire housing or heat sink. It is recommended to use
thermal paste. In order to balance possible unevenness,
the material should be applied as thinly as possible, but as
thickly as necessary. In this way, air inclusions, which may
otherwise occur, are replaced by TIM and the required
heat conduction between the back of the light engine and
the contact surfaces of the luminaire housing is achieved.
For this purpose, the planarity and roughness of the
surface should be optimized.
The list below is a selection of suppliers of thermal interface
materials. Additional suppliers for thermal management
support can also be found via OSRAM’s LED Light for You
network at www.ledlightforyou.com or at www.osram.com.

4.6 tc point location and temperature measurement
The tc point is the location where to check if the chosen
cooling solution (heat sink) is sufficient to ensure the LED
module performance. The tc point is located on the back
of the LED module under the center of the light-emitting
surface (see following image).
37.3
4.5 Cooling system and heat sink
For the selection of a suitable heat sink, several points
regarding thermal resistance have to be considered.
The selection is usually carried out through the following
necessary steps.
Notes:
A thermal design must always be confirmed by performing
a thermal measurement in steady-state condition. The
whole area of the PCB must be in full contact with the heat
sink.
tc point
To enable a lifetime of 50 000 (L70B50), the reference
temperature (tr) at the tc point must not exceed 80 °C.
The maximum temperature reached at the tc point must
not exceed 90 °C. A correct temperature measurement
can, for example, be performed with a thermocouple.

To measure the temperature and to ensure a good thermal
coupling between the LED module and the heat sink, you
should drill a hole into the heat sink and push the thermocouple through it. To ensure a direct contact between the
thermocouple and the PCB, it is recommended to glue the
thermocouple onto the PCB. You can, for example, use an
acrylic adhesive (e.g. type Loctite 3751).
Mounting of a PFA-insulated thermocouple by means of a
groove
It is also possible to use a sprung thermocouple. A suitable
type is: Electronic Sensor FS TE-4-KK06/09/2m. Please
note that a good thermal contact between the thermocouple and the PCB is required. Please refer to the datasheet and the application guideline of the manufacturer to
ensure correct handling.
Another possible way is to create a small groove along the
top surface of the heat sink and run the thermocouple
to the tc point inside the groove.
Notes:
Please keep in mind that you need a direct contact between
the thermocouple and the PCB. If you use TIM, you should
cut out a small area where the thermocouple has direct contact to the PCB.

PrevaLED ® Cube G3 LED modules | Lifetime and thermal behavior
5.2 Lifetime
The performance of PrevaLED® Cube G3 light engines is
measured at a typical tc of 75 °C. The maximum temperature at the tc point must not exceed 80 °C to achieve the
expected lifetime (L70B50) of 50 000 hours. The maximum
temperature at the tc point to cover the operational warranty
of the light engine is 90 °C. A warranty of 5 years can
­only be given if the light engine is not operated above a tc
point temperature of 75 °C. Please note that as the tc increases, the lifetime of ­PrevaLED® Cube G3 light engines
decreases. Moreover, the failure rate will also increase.
