Abstract
A light source system (), comprises: a light-emitting device () for emitting a first light and a second light in sequence; a beam splitting system () with which the first light emitted from the light-emitting device () is divided into one beam in a first range of wavelength and the other beam in a second range of wavelength, respectively emitted along a first optical path and a second optical path, and also with which at least a part of the second light emitted from the light-emitting device () is emitted along the first optical path; a first spatial light modulator () for modulating the beam emitted from the beam splitting system () along the first optical path; a second spatial light modulator () for modulating the beam emitted from the beam splitting system () along the second optical path. The light source system () has the advantages of high light-emitting efficiency and low cost. A projection system comprising the aforementioned light source system () is also provided.
