LIGHT SOURCE APPARATUS, IMAGE DISPLAY APPARATUS, AND OPTICAL UNIT

摘要

A light source apparatus includes a light source unit and an output unit. The light source unit includes at least one solid-state light source capable of outputting light in a predetermined wavelength range as output light. The output unit includes a light emitter and a base unit. The light emitter is excited by the output light from the light source unit and emits visible light with a wavelength different from a wavelength of the output light. The base unit is rotatable about a predetermined rotation axis and contains a crystalline member having a crystal axis direction set to a direction different from a direction orthogonal to an optical axis direction of the output light, the light emitter being supported in the optical axis direction. The output unit is capable of outputting combined light containing the light in the predetermined wavelength range and the visible light emitted from the light emitter.
