    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: 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: Lighting systems and devices offer dynamic control or tuning of a color characteristic, e.g. color temperature, of white light. The exemplary lighting systems and devices are used for general lighting applications that utilize solid state sources to pump remotely deployed phosphors. Two or more phosphors emit visible light of different visible spectra, and these spectra are somewhat broad, e.g. pastel, so that combinations thereof can approach white light temperatures including points along the black body curve. Independent adjustment of the intensities of electromagnetic energy emitted by the solid state sources adjusts levels of excitations of the phosphors, in order to control a color characteristic of the visible white light output of the lighting system or device.

    摘要: A solid state white light emitting device includes a semiconductor chip producing near ultraviolet (UV) energy. 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 a range along the black body curve.

    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: For general lighting applications, a semiconductor chip produces near ultraviolet (UV) electromagnetic energy in a range of 380-420 nm, e.g. 405 nm. Semiconductor nanophosphors, typically doped semiconductor nanophosphors, are remotely positioned in an optic of a light fixture. Each phosphor is of a type or configuration that when excited by energy in the 380-420 nm range, emits light of a different spectral characteristic. The nanophosphors together produce light in the fixture output that is at least substantially white and has a color rendering index (CRI) of 75 or higher. In some examples, the fixture optic includes an optical integrating cavity. In the examples using doped semiconductor nanophosphors, the visible white light output exhibits a color temperature in one of the following ranges along the black body curve: 2,725±145° Kelvin; 3,045±175° Kelvin; 3,465±245° Kelvin; and 3,985±275° Kelvin.
