Abstract
A projector system includes a light source module and an integrator including a light receiving surface for receiving light from the light source module. The light source module includes a number of light sources for emitting parallel light, multiple sets of light-adjusting prisms corresponding to the light sources and a focusing lens arranged near the integrator. 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. An angle of the light cone is 1/N of a cone formed by the light without being refracted, where N is number of the light sources and is greater than 1.
