Light source apparatus and image projection apparatus

摘要

A light source apparatus includes a light source unit that includes plural sets of a laser and a coupling lens corresponding to the laser, which are circumferentially provided to form a circle; and a reflecting unit placed within the circle and provided with plural reflecting surfaces corresponding to the lasers of the plural sets of the light source unit to be formed in a cone shape, the light irradiated from each of the lasers being injected into the corresponding reflecting surface via the corresponding coupling lens.

1. A light source apparatus comprising:
a light source unit that includes plural sets of a laser and a coupling lens corresponding to the laser, which are circumferentially provided to form a circle; a reflecting unit placed within the circle and provided with plural reflecting surfaces corresponding to the lasers of the plural sets of the light source unit to be formed in a cone shape, the light irradiated from each of the lasers being injected into the corresponding reflecting surface via the corresponding coupling lens; a support member on which the lasers and the coupling lenses of the plural sets are fixed; and a radiation member provided at a surface of the support member opposite to the side where the light paths of the lights irradiated from the lasers of the sets are formed, and including a flat surface formed at a center portion, a sloped guide surface which is provided at the outer side of the flat surface to be concaved downward such as to become deeper the closer the sloped guide surface becomes to an outer periphery of the radiation member from the flat surface, and plural fins provided to rest on the concaved sloped guide surface.
