Patent ID: 8167440

Claim:
A light source apparatus comprising: a light source unit comprising (i) a light source group in which a plurality of light sources are arranged into rows and columns so as to form a planar configuration, and (ii) a primary reflecting mirror group disposed on an optical axis of the light source group to reflect light beams emitted from the light source group as light beams which are reduced in a column direction by narrowing intervals between the rows of light beams emitted from the light source group; a light emitting wheel disposed on an optical axis of a light beam emitted from the light source unit; a wheel motor for driving to rotate the light emitting wheel; a single-color light emitting device; a light gathering optical system for making an optical axis of a light beam emitted from the light emitting wheel and an optical axis of a light beam emitted from the single-color light emitting device coincide with each other so that the light beams are gathered onto a predetermined plane; wherein the light emitting wheel includes at least a diffuse transmission area which diffuses light emitted from the light source unit and a fluorescent reflecting area which includes a fluorescent material which emits light in a predetermined wavelength band, the diffuse transmission area and the fluorescent reflecting area being provided end to end in a circumferential direction.
