摘要： Many applications of radiant energy transducer systems call for specific performance characteristics over desired fields of view or footprints on identified surfaces. Constructive occlusion utilizes a mask sized and positioned to occlude an active optical area, such as an aperture of a diffusely reflective cavity, so as to provide a tailored performance characteristic. Use of principles of constructive occlusion alone or in combination with several other techniques enable tailoring of the illumination distribution or the sensitivity profile of a radiant energy transducer system to meet the demands of specific applications. One mechanism used to further tailor performance involves a non-diffuse reflective shoulder along a peripheral section of the mask and cavity type system. Another technique involves using a retro-reflective surface, for example along a portion of the periphery of the system, to limit the angular field of view and to redirect light back into the system for emission within the desired field. Another technique involves use of a reflective wall along one side of the system, to limit the field of view to angles on the opposite side of the axis of the mask and cavity configuration.

摘要： A conical deflector receives light from a source through an opening at the narrow end of the cone. In one embodiment, an optical fiber bundle supplies light directly into the cone. In another embodiment, the conical deflector receives light via an optical integrating cavity. A substantial portion of the inner surface of the cones has a specular reflectivity. The entire surface may be uniformly specular (e.g., highly specular). Alternatively, one or more sections of the inner walls of the cone may have a diffuse reflectivity or a different degree of specular reflectivity (e.g., quasi-specular). The deflector is dimensioned relative to a narrow, desired field of view and the light source to deflect light that would otherwise pass out of the desired field of view, so as to efficiently illuminate the desired field of view. The conical deflector provides a substantially uniform light intensity distribution over the desired field of view.

摘要： Where a lighting device uses solid state emitters and an optic processes light from the emitters, it may improve efficiency in light extraction from the emitters to have an index of refraction matching material in between emitter output and a surface of solid of the optic that receives emitted light. However, such improved out-coupling or extraction efficiency may cause an overall color shift in the output of the overall lighting device, for example, if improved emitter output reduces internal reflection and associated internal phosphor excitation. To reduce the color shift in the output of the lighting device, the device may have index matching material used in association with one or some of the solid state light emitters but not all of the emitters, so that the combined light output of the device exhibits a desired spectral characteristics, e.g. remains a desirable color of white light.

摘要： A solid state white light emitting device includes a semiconductor chip producing near ultraviolet (UV) electromagnetic energy in a range of 380-420 nm, e.g. 405 nm. The device may include a reflector forming and optical integrating cavity. Phosphors, such as doped semiconductor nanophosphors, within the chip packaging of the semiconductor device itself, are excitable by the near UV energy. However the re-emitted light from the phosphors have different spectral characteristics outside the absorption ranges of the phosphors, which reduces or eliminates re-absorption. The emitter produces output light that is at least substantially white and has a color rendering index (CRI) of 75 or higher. The white light output of the emitter may exhibit color temperature in one of the following specific ranges along the black body curve: 2,725±145° Kelvin; 3,045±175° Kelvin; 3,465±245° Kelvin; 3,985±275° Kelvin; 4,503±243° Kelvin; 5,028±283° Kelvin; 5,665±355° Kelvin; and 6,530±510° Kelvin.

摘要： An optical position tracking system that tracks the position of objects, using light intensity and/or frequency with the application of geometry and ratios of detector responses, is provided, having light distributing and light detecting components that employ the concepts of constructive occlusion and diffuse reflection. Diffusely reflective cavities, masks and baffles are used to improve certain radiating characteristics of the distributing components and certain response characteristics of the detecting components, to tailor the radiation and detection profiles thereof, including them substantially uniform for all angles within a hemispheric area which the distributing and detecting components face. The distributing and/or detecting components are partitioned with specially-configured baffles. A partitioned distributor has distinct emission sections where the sections can emit spectrally-different or distinguishable radiation. A partitioned detector has distinct detection sections where the sections can detect radiation from different directions. The system may be variously configured, to use different combinations of partitioned and nonpartitioned devices. In most configurations, a single head module provides one set of directional data about two coordinates (e.g., .rho. and .THETA.) for one reflector. An additional head module remotely positioned from the first head module can provide a second set of directional data for the reflector (e.g., .rho..sub.2 and .THETA..sub.2), for cross-referencing with the first set of directional data to obtain positional data in three dimensions of the object being tracked.

摘要： A tube lamp has a tubular portion that serves both as a light guide for energy from a solid state source and as a container for a material bearing a nanophosphor that is pumped by the energy from the source as the energy traverses the light guide. However, the tubular portion of the light guide also allows emission of light produced by the phosphor when excited. The material with the nanophosphor dispersed therein may appear either clear or translucent when the lamp is off and the nanophosphor is not excited by energy from the source.

摘要： A lamp uses a solid state source to pump one or more doped semiconductor nanophosphors to produce a light output of a desired characteristic. The nanophosphor(s) is dispersed in a material, examples of which include liquids and gases. Various nanophosphors are discussed. In the examples, the material with the doped semiconductor nanophosphor(s) dispersed therein appears at least substantially clear when the lamp is off. The exemplary lamp also includes circuitry for driving the solid state source and a housing that at least encloses the drive circuitry. The lamp has a lighting industry standard lamp base mechanically connected to the housing and electrically connected to provide electricity to the circuitry for driving the solid state source.
