Abstract: According to the characteristics of LED and its special collimator, it designs a kind of projection system with uniform illumination, based on the lightpipe lighting system, which has several advantages, such as a simple structure, a short period for developing, and low processing costs. The simulation results show that its uniformity is suitable for  medium demands.
