Abstract

A light source apparatus according to the present invention includes a phosphor wheel having a phosphor disposed in an annular shape on a disk-shaped base material, the phosphor serving to emit fluorescent light from excitation light, thereby forming an excitation light source having a predetermined color, and the phosphor having a discontinuous portion in a part of the annular shape, an excitation light source for emitting the excitation light with which a passage position of the circular phosphor is irradiated with respect to the phosphor wheel to be rotatively driven by the wheel motor, and a controller that controls light emission of the light source and the excitation light source synchronously with a position of the discontinuous portion with respect to an irradiation position of the excitation light.
