Due to the high efficacy of PrevaLED® Cube DC G1 LED modules, only a partial amount of the introduced electrical power has to be dissipated through the back of the LED module. The thermal power that has to be dissipated for PrevaLED® Cube DC G1 LED modules is given below.

Note: To ensure a safe and reliable operation, the module must be attached to a suitable cooling solution (e.g. a heat sink). Depending on the application and the chosen LED module, passive cooling can be sufficient. In critical applications (e.g. small available heat sink size or highly reduced airflow), active cooling may be required. Active cooling combines a heat sink with a fan or a similar device to maximize the thermal dissipation of the passive heat sink. 12 PrevaLED ® Cube DC G1 LED modules | Thermal considerations 5.1 Thermal interface material and other accessories When mounting a PrevaLED® Cube DC G1 LED module within a luminaire, it is recommended to use thermal interface material (TIM) between the back of the LED module and the luminaire housing or heat sink. It is recommended to use thermal paste, but thermal foil can also be used. 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 LED module and the contact surfaces of the luminaire housing will be achieved. For this purpose, the planarity and smoothness of the surface should be optimized. The list below is a selection of suppliers of thermal interface materials. Additional partners for thermal management support can also be found via OSRAM’s LED Light for You network: www.ledlightforyou.com. It is recommended that the whole area of the PCB of a PrevaLED® Cube DC G1 LED module is in contact with the solid material of the heat sink. The minimum area of the PCB that has to have contact with the solid material of the heat sink is 65 x 65 mm. A thermal system always depends on many factors, such as airflow, ambient temperature etc. Please check your entire cooling system by performing a thermal measurement in steady-state condition. The list below is a selection of suppliers of different cooling solutions.

The selection is usually done through the following necessary steps: Define boundary conditions Total power dissipation of the LED module, max. ambient temperature ta, max. reference temperature tr according to lifetime requirements Rth = Estimate heat sink thermal resistance on LED module level Select heat sink thermal resistance tr - ta Pth tr measured at the tc point Use the estimated Rth as a target for a possible heat sink profile and examine the performance curve in the heat sink manufacturer’s catalog. 13 PrevaLED ® Cube DC G1 LED modules | Thermal considerations 5.3 Tc point location and temperature measurement The tc point is the location to check if the chosen cooling solution (heat sink and TIM) is sufficient to ensure the LED module's performance. The tc point is located on the back of the LED module under the center of the diffuser (see image below). To measure the temperature and to guarantee a good thermal coupling between the LED module and the heat sink, drill a hole into the heat sink and push the thermocouple through the heat sink. To ensure a direct contact between the thermocouple and the PCB, it is recommended to glue the thermocouple onto the PCB. tc point 37.7 41.4 All fi gures in mm Location of the tc point Thermocouple Use a thermocouple that can be glued onto the tc point. Make sure that the thermocouple is fixed with direct contact to the tc point. You can, for example, use an acrylic adhesive (e.g. type Loctite 3751). 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.

The maximum temperature at the tc point must not exceed 80 °C* to have an expected lifetime (L70B50) of 50 000 hours. For the definition of the lifetime of an LED module, please refer to IEC/PAS 62717, where the following types are defined (examples): — L0C10 is the lifetime where the light output is 0 % for 10 % of the LED modules. — L70F50 is the lifetime where the light output is ≥70 % for 50 % of the LED modules. F value includes reduction of lumen output over time including abrupt degradation (flux = 0). — L70B50 is the lifetime where the light output is ≥70 % for 50 % of the LED modules. B value includes only gradual reduction of lumen output over time (not the abrupt degradation of flux). — If the performance temperature tp of 70 °C is maintained, the PrevaLED® Cube DC G1 LED modules have an average lifetime of 50 000 h (L80B50 and L0C10). The maximum temperature measured at the tc point must not exceed 100 °C. Note: Higher temperatures lead to a shorter lifetime of the PrevaLED® Cube DC G1 LED modules. Moreover, the failure rate will also increase. The following tables show the lifetime of PrevaLED® Cube DC G1 LED modules according to IEC/PAS 62717.

The LED module has to be protected by a suitable IP classification of the luminaire housing. Please consider the luminaire standard IEC 60598-1 as well as the different requirements for indoor and outdoor application. kg tc point 83 All fi gures in mm 7.2 3D drawing For 3D files of PrevaLED® Cube DC G1 LED modules, please go to: http://www.osram.com/prevaled. Enable 3D View Note for France: Due to specific national regulations, as defined in the standard EN 60598, it is not permitted to expose the light engine outside a luminaire housing.* 7.4 Mounting To fix a PrevaLED® Cube DC G1 LED module to a heat sink, use M4 cylinder head screws according to DIN 912 or ISO 4762. The required torque is 1 Nm (± 0.5 Nm). Move me! Movable 3D PrevaLED ® Cube DC G1 LED module (works with Adobe Acrobat 7 or higher) PrevaLED® Cube ADP (EAN 4052899055590) As an accessory to the PrevaLED® Cube DC G1 LED modules, a heat sink adapter is available to match the geometric dimensions for available off-the-shelf accessories. Note: The PrevaLED® Cube ADP is not a sufficient heat sink for all PrevaLED® Cube LED modules. For further information on thermal design, please refer to chapter 5: Thermal considerations. 7.3 Mechanical protection of the LED module The housing of a PrevaLED® Cube DC G1 LED module should not be exposed to strong mechanical stress. Please apply force only to the dedicated mounting positions. Strong mechanical stress can lead to irreversible damage of the LED module. Mount the LED module from the top. Note: Make sure that the cover of the LED module cannot be removed. Therefore, provide sufficient fixation of the cover, e.g. by screwing it to the heat sink. 7.5 Protection from corrosion To avoid corrosion of electronic parts (such as LEDs) it is necessary to avoid corrosive atmosphere around the components. In case of LEDs, e.g. H2S is a highly corrosive substance which could lead to a drastically shortened product lifetime. The source for H2S are sulfur-cross-linked polymers – such as rubber. To ensure the absence of H2S, we recommend using peroxide cross-linked materials, which are available on the market as an alternative to sulfur-cross-linked versions. The general topic corrosion by moisture has to be ensured within the appropriate luminaire housing (see chapter 3: Ingress protection). * This fact is subject to change – please check the latest version of EN 60598. 17 PrevaLED ® Cube DC G1 LED modules | Norms and standards 8 Norms and standards Safety: IEC/EN 62031 IEC/EN 60598-1 Photobiological safety: IEC/EN 62471 Risk group 1 Electromagnetic compatibility: CISPR 15 IEC/EN 61547 IEC/EN 61000-3-2 IEC/EN 61000-3-3 EN 55015 Ingress protection: IP20 Approvals: UL 8750 recognized 18 01/14 OSRAM S-GI MK EM Subject to change without notice.
