摘要：

Heat dissipation is a crucial issue for development and applications of high power LEDs. In this paper, heat conductions of various light sources are compared, and the necessity of heat dissipation of high -power LEDs was further pointed out. The packaging structure of high power LEDs is introduced, and the heat transfer procedure is analyzed. Finally, some considerations to dissipate heat effectively to keep good performance of high-power LEDs are given.
