Light Source Utilizing Wavelength Conversion

Abstract

There is herein described a light source comprising a semiconductor device emitting a primary light, a thermally conductive optic having a reflective coating and a wavelength converter having a front surface and a rear surface. The optic is mounted to the rear surface of the wavelength converter and the primary light impinges on the wavelength converter in an emission region. The wavelength converter converts at least a portion of the primary light into a secondary light that is emitted from the front and rear surfaces of the converter and the optic reflects secondary light emitted from the rear surface back into the emission region. The light source may be used in either transmissive or reflective configurations.
