Analysis of heat dissipation for Integrated High Power LED Lamp

摘要

LED light source is considered as one of the important way for power saving and environmental protection. In this paper, a heat dissipation method for integrated high power LED lamp was investigated to solve its heat dissipation problem in engineering application. Firstly, the heat generation characteristics of integrated high power LED light source and the demand of heat dissipation of LED lamp were analyzed, and a heat dissipation analytic model was set up. Secondly, optimization of fins of radiator was carried out and optimal result was obtained. Thirdly, the result was applied to guide the radiator design of integrated high power LED street lamp. Lastly, the numerical simulation and temperature experiment of radiator were performed. Experiments shown that the radiator design satisfies the demand. It is of importance to guide the radiator design for LED Lamp.
