In this paper, a thermal simulation model of a LED driver was established. The thermal field and thermal stress analysis of the driver was done by using the software EFD Pro 8.2, and the temperature rise from various parts and the temperature field distribution of the PCB were obtained. By analyzing the reasons leading to overheating and unideal heat distribution, corresponding thermal simulation using an improved model was carried out. Finally, the comparison and analysis of experimental measurement results and simulation results were given.
