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.

Abstract: Optical elements having components made from high refractive index materials (RI≦1.6) and lamp assemblies incorporating such elements. Various optical elements, such as total internal reflection lenses, can be fabricated from materials having a higher index of refraction than materials typically used in such elements. The compact optical elements have at least one internal reflection surface that directs radiant energy (e.g., light) from a receiving end to a transmitting end. By using a high refractive index material, a lens can be fabricated that directs a greater portion of the light emitted from a source into the lens toward the transmitting end of the lens. Thus, less of the light spills out of the lens at a surface where emission is not intended, reducing the number of lossy bounces needed to direct the light in a particular direction.

Abstract: A hybrid reflector system for use in lighting application. The system is particularly well-suited for use with solid state light sources, such as light emitting diodes (LEDs). Embodiments of the system include a bowl-shaped outer reflector and an intermediate reflector disposed inside the bowl and proximate to the light source. The reflectors are arranged to interact with the light emitted from the source to produce a beam having desired characteristics. Some of the light passes through the system without interacting with any of the reflector surfaces. This uncontrolled light, which is already emitting in a useful direction, does not experience optical loss normally associated with one or more reflective bounces. Some of the light emanating from the source at higher angles that would not be emitted within the desired beam angle is reflected by one or both of the reflectors, redirecting that light to achieve a tighter beam.
