The characteristics of driving power and thermal radiation for high-power LED light source are ana-lyzed. Based on the research on application efficiency, light source heat generation, heat conduction and heat cur-rent characteristics of high power LED driving power, a method of improving driving circuit and structure design is proposed. The efficiency of the power source is improved and the thermal loss is reduced through boost-buck con-stant current circuit as well as using the frequency transformer rectifier in the driving circuit. For structure design, thermal radiation effect is improved further through optimizing the materials for the fins and interfaces, improving the fins structure, installing heat pipes and temperature equalization plate. So the quality and performances of the product will be better.
