5.7.1 General information for cooling options:
The operation of high-power LEDs requires a thermal management for the LED
module. Less cooling might result in damage of the LED module caused by over-
temperature of the LEDs.
The cooling options must be set in relation to the total power input to the LED module.
The total power input is influenced by:
-
Current set in the controller
-
Duty cycle of LED operation in pulsed operation.
The ability to dissipate heat from the LED for the single cooling options is influenced by:
-
Ambient temperature
-
Orientation of the module
