Second optimization of heat dissipation for integrated high power LED was investigated to solve the problem of heat dissipation in engineering applications. Firstly, the heat generation characteristics of integrated high power LED and the demand of heat dissipation of LED street lamp were analyzed, and a heat dissipation analytic model was set up. Secondly, optimization of fins of shape and layout was carried out and optimal result was obtained. Combining actual production demand, parameters of radius and height of boss and angle of demould were extracted and second optimized, then optimal result was obtained. Thirdly, the result was applied re guide the design of LED street lamp and radiator. Temperature experiments were carried out and the results show that the radiator design cnn satisfy the clernnncl
