HIGH EFFICIENCY LED LIGHT SOURCE ARRANGEMENT |
摘要 |
A light source (100) comprises a number of optical components aligned concentrically along an optical axis (115). The optical components include an array of light emitting diodes (101), a dielectric collimator (109) having surfaces configured to provide total internal reflection of light emitted from the array of diodes, and a second stage reflector (113) to further collimate the beam and which also may be based on total internal reflection by a prism structure on the outside.
