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.
