Abstract
Provided is an endoscope light source apparatus including: first and second solid-state light sources that emit first and second light beams, respectively; a third solid-state light source that emits a third light beam that generates white light by being combined with the first and second light beams; an optical member that combines the first, second, and third light beams to generate a combined light; an optical filter that is provided so as to be insertable into/retractable from an optical path of the combined light; and a controller, wherein, in a first excitation-light illumination mode, the controller turns on the first and second solid-state light sources and weakly turns on the third solid-state light source, and, in a second excitation-light illumination mode, turns on the first solid-state light source, turns off the second solid-state light source, and weakly turns on the third solid-state light source.
