HIGH BRIGHTNESS ILLUMINATION DEVICE WITH INCOHERENT SOLID STATE LIGHT SOURCE |
摘要 |
An illumination light source includes an incoherent solid state light source adapted to emit light over at least one light emission surface (212) and having a total light emission surface area So; a light circulation device (220) including at least one light receiving surface (222) adapted to receive the light from the incoherent solid state light source, and a light extraction area (224) having a first surface area S1; and a light extraction device (230) for extracting the light from the light circulation device at the light extraction area, wherein S1<So. Accordingly, the apparent brightness of the light is increased by distributing it over a smaller area. Embodiments involving light emitting diodes (LED)are described. |
