Almost every aspect of the high-power panel lights

Almost every aspect of the high-power panel lights is linked to the junction temperature of the LED. These aspects are the dominant wavelength, luminosity and the forward voltage and they are the most important criteria of the high-power LED.

One significant thermal problem with high-power LEDs is called "thermal runaway". It happens because when the colour sensor reports that the luminous intensity is not high enough the processor drives the LED harder and by doing this it uses more power and when more power is used more heat is generated. More heat means higher junction temperature and higher junction temperature again decrease the luminous intensity. And again the colour sensor reports low light emission and the process circles all over again until the temperature of led lighting panel reaches critical state and the LED overheats and permanently fails.
