| 发明名称 | Front-end lighting system for projection and projection device | ||
| 摘要 | A front-end lighting system for projection includes: a RGB three-color LED light source, configured to generate three monochromatic lights; a reflector, configured to perform a first light mixing operation on three monochromatic lights generated by the RGB three-color LED light source; a first group of relay lenses, configured to adjust a light path; and a compound eye field lens, configured to perform a second light mixing operation on the three monochromatic lights generated by the RGB three-color LED light source. The reflector includes a reflecting surface, and three monochromatic lights emitted by the RGB three-color LED light sources, after being reflected by the reflecting surface of the reflector, pass through the first group of relay lenses and the compound eye field lens in sequence. | ||
