一种投影仪及其光源系统

Projector and light source system thereof

Abstract

The present invention discloses a light source system and a projector. The light source system comprises a color wheel assembly comprising a fluorescent wheel, a light source device used for emitting the exciting light, wherein the exciting light forms a convergence light spot on the fluorescent wheel to excite the fluorescent wheel to generate the fluorescence; a reflector possessing a concave reflection surface of which an opening faces the color wheel assembly, arranged aslant relative to the color wheel assembly and used for reflecting the fluorescence out of the fluorescent wheel. In the light source system, by arranging the reflector aslant relative to the color wheel assembly, the fluorescence can be reflected out of the fluorescent wheel after passing the reflector, so that a light pipe is saved in the structure of the system, and the size of the light source system is reduced significantly. The present invention also provides a projector comprising the above light source system, thereby being able to reduce the size of the light source system significantly.
本发明公开了一种光源系统及投影仪,该光源系统包括:色轮组件,所述色轮组件包括荧光轮;光源装置,所述光源装置用于发射激发光,所述激发光在所述荧光轮上形成汇聚光斑,激发所述荧光轮生成荧光;反射镜,所述反射镜具有开口朝向所述色轮组件的凹反射面,所述反射镜相对于所述色轮组件倾斜设置,用于将所述荧光反射至所述荧光轮之外。在光源系统中,通过将反射镜相对于所述色轮组件倾斜设置,可以使得荧光经过反射镜后反射至荧光轮之外,从而可以在系统结构中去掉方棒,大幅度缩小光源系统的体积,本发明还提供了一种包括上述光源系统的投影仪,能够大幅度缩小光源系统的体积。
