Abstract
[Solving Means] A light source apparatus includes a light source unit, a rotor, and a ventilation structure. The light source unit includes a light source, an optical device that collects light from the light source at a light collecting position, and a housing having an opening at the light collecting position that houses the light source and the optical device. The rotor has a wavelength conversion region that is arranged on a light irradiation region which is irradiated with light, the light being collected at the light collecting position and emitted outside the housing via the opening, the rotor being disposed rotatably about a rotation axis. In the ventilation passage, at least a part of the rotor is arranged.
Claims11
A light source apparatus, comprising:
- a light source unit that comprises:
- a housing, wherein the housing comprises an opening at a light collecting position;
