摘要： A light source device includes a first light-source unit, a second light-source unit, and a third light-source unit emitting light of spectra different from each other. Each of the first through third light-source units includes a heat dissipator and a light source. The light source includes a light emitting device. The heat dissipators of the first through third light-source units are disposed in an ascending order of values of T/Q of the first through third light-source units, in a direction of cooling air flow. “Q” represents a heat generation amount from the light source of each of the first through third light-source units, when the light sources are driven to obtain predetermined light intensity and lifespan. “T” represents a preset, upper-limit temperature for the light emitting device of each of the first through third light-source units to obtain the predetermined light intensity and lifespan.
