Abstract

프로젝터에 사용되는 조명장치로서, 광원으로부터 입사되는 광빔을 균일한 광 강도분포로 출사시키기 위한 스크램블러를 이용한 프로젝터용 조명장치가 개시되어 있다. 개시된 조명장치는 광의 입사각에 따른 출사각 변동이 작도록 그 입사단보다 큰 단면적의 출사단을 가지며 그 입사단과 출사단 사이의 벽면이 중심축선에 대해 평면이 되며, 그 내부에 공동이 형성된 개선된 스크램블러를 가진다. 이 스크램블러를 이용한 조명장치에 의하면 그 개선된 스크램블러의 입사각에 비해 작아지므로 그 출사광의 이용효율을 극대화시키는 데 효과적이다.

Claims (1)

  1. 광원과 이 광원 주위에서 광빔을 모으는 반사경과, 그리고 이 반사경에 의하여 모아지는 광빔이 입사하는 입사단과 그 광빔이 출사하는 출사단 및 그 입사단과 사이에서 광빔을 반사 확산시키는 벽면을 가지는 스크램블러를 구비하여 된 프로젝터용 조명장치에 있어서, 상기 스크램블러가 상기한 입사단보다 큰 단면적의 출사단을 가지며, 그 내부에 공동이 형성되어 있는 것을 특징으로 하는 프로젝터용 조명장치.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
