Patent ID: 7972016

Claim:
A projector system comprising: a light source module, the light source module comprising a plurality of light sources capable of emitting parallel light, a plurality of sets of light-adjusting prisms corresponding to the plurality of light sources, and a focusing lens; the plurality of sets of light-adjusting prisms arranged between the plurality of light sources and the focusing lens; and an integrator including a light receiving surface for receiving light from the light source module, the integrator arranged at a side of the focusing lens opposite to the light-adjusting prisms; wherein light emitted from each of the light sources is refracted by the corresponding set of light-adjusting prisms, and then focused by the focusing lens to the light receiving surface of the integrator, and forms into a converging light cone with the apex being at the light receiving surface of the integrator, and an angle of the light cone is 1/N of that of a light cone formed by the light without being refracted, where N is the number of the light sources and is greater than 1.
