摘要:

The reliability of power LEDs has strong dependence on successful package thermal management. In this paper, heating response curves of LEDs were recorded by the temperature sensitive parameter (TSP) method and fast-switching circuit techniques. It provided a novel method to analyze thermal resistance composition of power LED's packaging. Cover-and-block method was presented to provide a correction to the apparent thermal resistance of optical devices, and an electrical method to obtain radiant efficiency was also put forward.
