REFLECTOR SYSTEM FOR LIGHTING DEVICE
First Claim
1. A light emitting device, comprising:
- a multi-element light source mounted at the base of a secondary reflector, said secondary reflector adapted to shape and direct an output light beam; and
a primary reflector disposed proximate to said light source to redirect light from said source toward said secondary reflector, said primary reflector shaped to reflect light from said multi-element source such that the light is spatially mixed prior to incidence on said secondary reflector.

Abstract
A reflector system for a lighting device. The system uses two reflective surfaces to redirect the light before it is emitted. The light source/sources are disposed at the base of a secondary reflector. The first reflective surface is provided by a primary reflector which is arranged proximate to the source/sources. The primary reflector initially redirects, and in some cases diffuses, light from the sources such that the different wavelengths of light are mixed as they are redirected toward the secondary reflector. The secondary reflector functions primarily to shape the light into a desired output beam. The primary and secondary reflectors may be specular or diffuse and may comprise faceted surfaces. The reflector arrangement allows the source to be placed at the base of the secondary reflector where it may be thermally coupled to a housing or another structure to provide an outlet for heat generated by the sources.

29. A lamp device, comprising:
-
a multi-element light source; a protective housing that surrounds said light source, said housing having an open end through which light may be emitted; a secondary reflector disposed inside said housing and around said light source such that said light source is positioned at the center of the base of said secondary reflector; a primary reflector disposed to reflect light emitted from said source toward said secondary reflector such that said light is spatially mixed prior to incidence on said secondary reflector; and a lens plate disposed over said open end of said housing. - View Dependent Claims (30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57)
