Reliability Test and Simulation Analyses for High Power LED
High power LED products intended for outdoor applications need specific tests to evaluate its reliability. In this paper acceleration tests for LED samples at high temperatures and currents below the rating conditions, have been carried out. Considering the high junction temperature of LED chip is the main reason which caused the decreased optical efficiency output, and the typical failure models for degradation of optical efficiency have been analyzed by reliability tests and simulation.
