Thermal analysis of high power LED packages under the alternating current operation

► We report on both experimental and analytical thermal analysis of AC driven LED packages. ► The variation of R th with the input power can be attributed to the h effect. ► The thermal resistance of AC driven LED can be lower than that from DC mode. In this paper we describe a novel thermal charact...
