Thermal management has always been crucial for the improving of LED reliability. Most researches focus on the thermal management outside the package like fin optimization, microchannel, microjet cooling, but few refer to the thermal management inside the package. In this paper, a contrast experiment was carried out by an online testing method to explore the LED's optical degradation under conditions...
