| description | The present invention relates to a light source device and an image projection apparatus including the same. The image projection apparatus adopts an excitation light source to excite a green light source among three color light sources to increase the amount of light, while limiting a position of the excitation light source and positions of the three color light sources based on the same, so as to downsize products of all the light source device and the image projection apparatus. In addition, by paying attention to the etendue physical quantity between the display panel and the green light source constituting an illumination system of the image projection apparatus and controlling the image size for the green light source formed by the excitation light source, a sufficient amount of light can be increased with a minimum amount of the excitation light source, thereby maximizing the light efficiency.
본 발명은 광원장치 및 이를 포함하는 영상투사장치에 관한 것이다. 상기 영상투사장치는 3색 광원 중 녹색 광원을 여기시키기 위한 여기광원을 채택하여 광량 증가를 도모하면서도 상기 여기광원의 위치와 이를 전제로 하여 3색 광원의 위치를 제한함으로써 광원장치 및 영상투사장치 전체의 제품 소형화가 가능하고, 또한 영상투사장치의 조명계를 구성하는 디스플레이 패널과 녹색 광원 사이의 에텐듀 물리량에 주목하여 이를 기준으로 여기광원에 의해 형성되는 녹색 광원에 대한 결상 크기를 제어함으로써 최소한의 여기광원 광량으로도 충분한 광량 증가를 도모할 수 있어 광효율이 극대화될 수 있다. |
