摘要： Provided is a medical light source device that includes a light source part including two or more semiconductor light-emitting devices having wavelengths of emitted light different from each other. The light source part generates light of predetermined chromaticity by mixing the light emitted from each of the semiconductor light-emitting devices and emits outward the generated light of the chromaticity as illumination light. The medical light source device further includes a control unit that controls a mixing rate of the light emitted from each of the semiconductor light-emitting devices based on a light amount setting value of the illumination light emitted from the light source part, and keeps the chromaticity constant regardless of a light amount of the illumination light.
