Solid-state light source device

Abstract

A solid-state light source device 1 includes a plurality of light source cells 10, a light combining device 20 combining light emitted from the plurality of light source cells and emitting combined light, and a light reflecting/combining unit 30 reflecting the light emitted from the light source cells and emitting the light to the light combining device. The light combining device 20 has a reflective plane on a surface thereof, has a plurality of columnar-shaped regions divided along emission directions in an interior thereof, and has wavelength selective reflective planes in interfaces between the columnar-shaped regions. The light reflecting/combining unit 30 is configured in a substantially paraboloidal shape having a reflective plane on a surface thereof. Accordingly, light use efficiency is improved, and light of a desired color can be selectively extracted.
