Abstract

프로젝터용 조명장치를 개시한다. 광원으로 발산되어 스크램블러로 입사되지 않는 광빔을 이용하기 위해, 광빔을 출사하는 광원과, 이 광원으로부터 입사된 광빔을 균일한 광 강도분포로 바꾸어 출사시키는 스크램블러를 구비하여 된 프로젝터용 조명장치에 있어서, 상기한 광원과 상기 스크램블러 사이에는 그 스크램블러로 입사되지 않는 광빔을 굴절시켜 그 스크램블러로 접속시키는 위상지연 보정젠즈부재부재를 포함한다.Disclosed is a lighting device for a projector. In order to use the light beam emitted by the light source and not incident to the scrambler, a light source for emitting the light beam, and a scrambler for converting the light beam incident from the light source into a uniform light intensity distribution, the illumination device for a projector And a phase delay correcting member member between the light source and the scrambler for refracting and connecting the light beam that is not incident to the scrambler to the scrambler.

이러한 위상지연 보정렌즈부재를 구비한 조명장치를 사용함으로서, 스크램블러로 입사되지 않고 발산되어 버렸던 광빔을 이용할 수 있어 광효율을 향상시킬 수 있다.By using the illumination device provided with such a phase delay correcting lens member, it is possible to use a light beam that has been diverged without being incident to the scrambler, thereby improving the light efficiency.
