Core Z3 LED modules | Thermal considerations

Note: Please keep in mind that you need a direct contact

between the thermocouple and the PCB.

Note: If you use a TIM, please cut out a small area where

the thermocouple has direct contact to the metal-core

PCB.

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 ther-

mocouple and the PCB, it is recommended to glue the ther-

mocouple onto the PCB. You can, for example, use an acry-

lic 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 no-

te that a good thermal contact between the thermocouple

and the PCB is required. Please refer to the data sheet and

the application guideline of the manufacturer to ensure cor-

rect handling.

Another possible way is to create a small groove along the

top surface of the heat sink and run the thermocouple inside

the groove to the t

point.
