1. A light source apparatus comprising:
a light-emitting device group composed of a plurality of light-emitting diode chips for emitting lights of at least three colors, wherein for each of the at least three colors, the light-emitting diode chips for emitting light of that color form a light-emitting device color set, and wherein the light-emitting diode chips are located close to each other and are disposed symmetrically with respect to a central point such that, for each light-emitting device color set, a central position of the light-emitting diode chips forming the light-emitting device color set is coincident with the central point.
