Abstract

A light source system and projection system, the light source system comprising: a first light source () producing first wide spectrum light, a second light source () producing second wavelength light, a light splitting and light combining device () used to split and combine light, a first spatial light modulator (), a second spatial light modulator (), and a control device () controlling the first light source () and the second light source () and modulating the first spatial light modulator () and the second spatial light modulator (). The projection system comprises the light source system. The light source system and projection system have high brightness and wide color gamut, effectively eliminating rainbow effect, and also have a simple structure and low cost.
