LED junction temperature, what is the LED junction temperature, what causes the LED junction temperature, and what are the ways to reduce the LED junction temperature? The following will analyze in detail 1. What is the junction temperature of the High power LED? The basic structure of High power LED is a semiconductor P-N junction. The experiment pointed out that when current flows through the LED element, the temperature of the P-N junction will rise. Strictly speaking, the temperature of the P-N junction area is defined as the junction temperature of the LED. Usually because the component chips have a small size, we can also regard the temperature of the LED chip as the junction temperature. 

2. What are the reasons for the LED junction temperature?
