摘要
大功率RGB三色LED的体积小、重量轻,成为投影仪、背投电视等显示仪器的新型光源。本文研究了基于RGB三色LED的数字微反射镜的照明系统的设计方法,给出了光源和照明系统的设计结果,并对照明结果进行了分析。基于该新型光源的数字微反射镜照明系统与传统照明系统相比,具有结构简单、体积降低、重量减轻、节能环保等优点。
The apperance of three color lighting-emitting diode(LED) makes digital micro-mirror(DMD) device have simple configuration,light weight and small volume.In this paper a three color LED illumination system for DMD device is designed based on the character research of high power three color LED.This system mainly includes three color LED,optical tube,convergent lens.The application of this system is projector,rear-projection TV,display and etc.
