Document Type and Number:
WIPO Patent Application WO/2016/070705
Kind Code:
A1
Abstract:
A light source system and a projector comprising same, said light source system comprising: a color wheel assembly (230), the color wheel assembly (230) comprising a fluorescent light wheel (231); a light source apparatus (210), the light source apparatus (210) being used for emitting an excitation light; the excitation light forms an aggregated light spot on the fluorescent light wheel (231) and excites the fluorescent light wheel (231) to generate fluorescent light; a reflective mirror (220), the reflective mirror (220) having an opening facing the concave reflective side of the color wheel assembly (230); the reflective mirror (220) is disposed obliquely relative to the color wheel assembly (230) and is used to reflect the fluorescent light to outside of the fluorescent light wheel (231). In the light source system, by disposing the reflective mirror (220) obliquely relative to the color wheel assembly (230), the fluorescent light is reflected by the reflective mirror (220) to outside of the fluorescent light wheel (231), thereby enabling the removal of the square rod in the system structure, substantially reducing the volume of the light source system.
