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 translation: 具有由高折射率材料（RI@1.6）制成的元件的光学元件和并入这些元件的灯组件。 诸如全内反射透镜的各种光学元件可以由具有比在这些元件中通常使用的材料更高的折射率的材料制成。 紧凑的光学元件具有至少一个内部反射表面，其将辐射能（例如，光）从接收端引导到发射端。 通过使用高折射率材料，可以制造将来自源的光的更大部分引导到透镜中的透镜朝向透镜的透射端的透镜。 因此，较少的光在不需要发射的表面处从透镜中流出，减少了在特定方向上引导光所需的有损跳跃的数量。

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: An indirect troffer-style lighting fixture that is particularly well-suited for use with solid state light sources. An elongated heat sink with a mount surface for light sources runs longitudinally along the fixture. To facilitate heat dissipation, a portion of the heat sink is exposed to the ambient room environment. An elongated specular reflector also runs along the device proximate to the heat sink. The heat sink and the specular reflector are mounted such that a spatial relationship is maintained. Some of the light from the sources impinges directly on the specular reflector and is redirected towards a back surface. The back surface defines a luminous surface that receives light directly from the sources and redirected light from the specular reflector. The back surface and the heat sink mechanically obscure any images of the light sources in the specular reflector such that they are not visible in a viewing area.

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.

Abstract: A solid state lighting device includes a device-scale stamped heatsink with a base portion and multiple segments or sidewalls projecting outward from the base portion, and dissipates all steady state thermal load of a solid state emitter to an ambient air environment. The heatsink is in thermal communication with one or more solid state emitters, and may define a cup-like cavity containing a reflector. At least a portion of each one sidewall portion or segment extends in a direction non-parallel to the base portion. A dielectric layer and at least one electrical trace may be deposited over a metallic sheet to form a composite sheet, and the composite sheet may be processed by stamping and/or progressive die shaping to form a heatsink with integral circuitry. At least some segments of a heatsink may be arranged to structurally support a lens and/or reflector associated with a solid state lighting device.
