| Abstract: | An excellent design of epoxy resin structure is very important to improve the LED device optical performance and reduce the experiment cost.The designing and simulating of LED packages are completed based on the non-sequence ray tracking theory.Some correlative parameters of the epoxy resin structure and material are changed and analyzed so as to obtain the regularity of the intensity distribution.The simulated results will provide some useful referrence for LED packaging computer-aided design. |
