Thermal Analysis of High-Power LED Tube Lamp
Heat dissipation of high-power LED lamps has become a key technology to LED package due to the improvement of the LED output power. A detailed simulation of temperature distribution of three chips high-power LED tube lamp was made by finite element method. Based on the consistency of the LED lamp experimental and simulation results, the analyses of the effect of thermal conductivities of PCB, thermal grease, heat sink, convection coefficients and the length of the lamp on the junction temperature were made, which provide an effective reference for the thermal design.
