摘要: 在方棒照明系统的基础上,根据LED的发光特性和独特的准直结构,设计了一款基于LED的均匀照明投影光路系统.其优点是结构简单、开发周期短、加工成本低.仿真结果表明,其均匀度能满足中等要求.

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.
