A Method of Estimating the Junction Temperature of Power LEDs in Luminaires
Abstract：This paper puts forward a new method by preserving a micro pad besides the LEDs on MCPCB（Metal-Core Printed Circuit Board）for estimating the junction temperature of power LEDs in luminaires,based on the analysis of thermal structure of SMD LED package.This method is tested by relative experiments involved in both single LED and several LEDs combined.
