7.1.2. Requirements for the heat sink
The heat sinks must be dimensioned to provide adequate cooling capacity.
The R value is important for selecting an appropriate heat sink. This value depends on the light output of the module and on the
th
ambient temperature in which the module is to be operated. The R value of the heat sink must be smaller than the required R
th th
value.
