摘要：
Due to Light Emitting Diode (LED) have the properties of compact size and high efficiency, there have more and more illumination system use it to be a lighting source. In this paper, a compact projection system was designed by a simple architecture. For this compact projection system, the prototype has been developed by using a single tranmissive light valve and LED source in it. With a simple collecting light reflector, a curved mirror and a light tunnel of the illumination system, the optical efficiency from the source to light valve is up to over 70% and the uniformity illuminated on the light valve is over 85%.
