PrevaLED ® Core Z3 LED modules | Thermal considerations 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® Core Z3 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® Core Z3 LED modules is given below. 4.
PrevaLED ® Core Z3 LED modules | Thermal considerations Please note: 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 contact with solid material of the heat sink. In the following, you find two examples of how to cool a PrevaLED® Core Z3 LED module. Location of the tc point Example 1: LED module: PL-CORE 1100-827 Heat sink: Fischer SK572 height: 37.
PrevaLED ® Core Z3 LED modules | Thermal considerations To measure the temperature and to ensure 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. You can, for example, use an acrylic adhesive (e.g. type Loctite 3751).
