Study on Measurement Method of Thermal Performances for High Power LED and its Applications
高功率LED热特性测试方法研究与应用

The maesurement principle and procedure based on the dynamic electrical measurement method for thermal resistance and junction temperature of high power LED and the factors which influenced measuring results were investigated. At the same time, the setup of the test system for the measuring of thermal resistance was designed. The experimental results show that the metod has the advantages of simple structure and good stability, and it can be performed to measure thermal resistance and junction temperature of high power LED as a effective measurement method.
