High brightness illumination device with incoherent solid state light source










Image Number 3 for United States Patent #7740375.

An illumination light source includes an incoherent solid state light source adapted to emit light over at least one light emission surface and having a total light emission surface area S.sub.0; a light circulation device including at least one light receiving surface adapted to receive the light from the incoherent solid state light source, and a light extraction area having a first surface area S.sub.1; and a light extraction device for extracting the light from the light circulation device at the light extraction area, wherein S.sub.1<S.sub.0. Accordingly, the apparent brightness of the light is increased by distributing it over a smaller area.
