Light source apparatus and image display apparatus

摘要

A light source apparatus includes: at least one solid-state light source configured to output light in a predetermined wavelength range; a first optical system including at least one aspherical surface configured to convert a light flux from the solid-state light source into a substantially parallel light flux; an output unit including at least one light emitter that is excited by the light and emits visible light with a wavelength longer than that of the light, the output unit being configured to output light containing the light and the visible light; and a second optical system including at least one concave reflecting surface and being configured to reflect the light on the concave reflecting surface, the light coming from the solid-state light source and being converted into the substantially parallel light flux by the first optical system, to collect the light to the light emitter of the output unit.

1. A light source apparatus, comprising:
a plurality of light source units, each including:
a solid-state light source configured to output light;a first optical system configured to convert light flux from the solid-state light source into a substantially parallel light flux; anda second optical system configured to direct the parallel light flux from the first optical system to a light collecting point; and an output unit including a light emitter that is excited by light from each of the light source units and a rotating wheel having an arrangement surface on which the light emitter is disposed, the rotating wheel being configured to rotate about a predetermined rotation axis extending in a direction perpendicular to the arrangement surface, wherein light reflected by the second optical systems of the respective light source units is directed to a plurality of light collecting points on the light emitter, the plurality of light collecting points being at different distances from the rotation axis.
