Abstract

이 발명은 박막투과형 액정소자 혹은 화상이 기록된 투명필름에 강한빛을 조사하여 스크린에 확대 투사시키는 투사기용 조명장치에 관한 것으로서, 반사경을 통해 나온광을 액정소자에 균일하게 조명할 수 있도록 복수개의 막대형 렌즈를 조밀하게 단을 지어 합친 상태의 막대형 렌즈다발을 설치함으로써, 반사경에 반사되어 나온광이 막대형 렌즈다발에 의해 액정소자 전체에 꽉 차게 조명되도록 하여 화면 전체를 균일하게 밝게 조명할 수 있도록 하는 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a projection apparatus for illuminating a thin film transmissive liquid crystal element or a transparent film on which an image is recorded and to project the light to a screen. By installing the rod lens bundles in which the rod-shaped lenses are densely arranged together, the light reflected from the reflector is illuminated by the rod lens bundles to the entire liquid crystal element so that the entire screen can be uniformly and brightly illuminated. To make it possible.
