Abstract :
It is difficult to measure the junction temperature of every chip in the light emitting diode (LED) integrated light source by using common experimental methods. In this paper, a model to simulate the whole temperature field in sources face of LED integrated light is proposed. Fourier-based solution is used to solve the heat equation in three dimensions. The thermal model is programmed by Matlab and has been validated by finite element method simulations. The comparison shows that the relative error between these two models is within 3.6%.
