What is the temperature tolerance of the LED module?
See the life requirements of your LED module. You can choose the LED with the LM-80 report. According to the data provided by its LM-80 report, the working current and temperature resistance of LED are finally determined. If necessary, LED derating can be achieved.
You can check the LED parameter manual you use. The maximum allowable junction temperature is 120 degrees C. Then look at the thermal resistance of the package, then the maximum allowable temperature for the LED pin is 120-Rja*P, where Rja is thermal resistance.
The temperature tolerance of the LED module is actually the temperature resistance of the LED above the module.The lower the junction temperature of LED, the longer its life will be. Therefore, it is necessary to deal with the heat dissipation of LED as much as possible.
