Research on the Radiator Structure for 4W High-power LED Lamp
Abstract：Based on the theory of thermal resistance, the heat conduction model of a 4W high-power LED lamp is obtained and the effective cooling area of the radiator is computed. According to the finite element method, the steady-state temperature distribution of the radiator is simulated, and using the EFD method the natural convection thermal analysis is conducted. Finally the heat experiment is conducted to verify the simulation results. The results show that the radiator meet the application requirement of LED, namely the maximum temperature is less than 65℃. The research will guide the design of LED lighting with high heat dissipation efficiency.
