Abstract

A light source apparatus includes a first light source unit including a first light emitting device, a second light source unit including second and third light emitting devices, a light beam conversion system, and a light ray combiner. The first, second, and third light emitting devices emit first, second, and third light beams, respectively. The combiner has first, second, and third areas which these light beams enter, respectively. One of the light beams is a specific light beam. The direction in which the second and third areas are arranged is a third direction. The conversion system converts the specific light beam such that the dimension of the specific light beam in the third direction at a stage in which the specific light beam enters the combiner is smaller than that at a stage in which the specific light beam exits the conversion system.
