    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.

    摘要： Many applications of radiant energy transducer systems call for specific performance characteristics over predetermined fields or surfaces. Constructive occlusion utilizes diffuse reflectivity and a mask sized/positioned to occlude an active optical area, such as an aperture of a reflective cavity, to provide tailored performance characteristics. Constructive occlusion alone or in combination with other techniques enable tailoring of the performance of a radiant energy transducer system to meet requirements 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 system. Another technique involves using a retro-reflective surface, for example along a portion of the periphery of the system. 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： 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., &rgr; and &THgr;) 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., &rgr;2 and &THgr;2), for cross-referencing with the first set of directional data to obtain positional data in three dimensions of the object being tracked. The system can also track multiple objects, using spectrally-different (or at least spectrally distinguishable reflectors) in conjunction with correspondingly spectrally-compatible sensors to distinguish between data collected for each reflector. Numerous variations particularly on the concept of constructive occlusion may be accomplished with varying results as desired or appropriate. By reconfiguring the radiation/detection surface, the cavity, the mask and/or the baffle, the radiation/detection profile may be varied in substantially unlimited ways.

    摘要： A quadrant light detector that employs the concept of constructed occlusion to improve its accuracy and by incorporating baffles within the design to improve its detection response to incoming light having an incidence angle near the horizon, and to divide a diffusely reflective cavity into quadrants. The quadrant detector is able to determine the direction, or azimuth and elevation, to the light source anywhere within a sector of a hemisphere or a sphere.

    摘要： A system to provide radiant energy of selectable spectral characteristic (e.g. a selectable color combination) uses an integrating cavity to combine energy of different wavelengths from different sources. The cavity has a diffusely reflective interior surface and an aperture for allowing emission of combined radiant energy. Sources of radiant energy of different wavelengths, typically different-color LEDs, supply radiant energy into the interior of the integrating cavity. In the examples, the points of entry of the energy into the cavity typically are located so that they are not directly visible through the aperture. The cavity effectively integrates the energy of different wavelengths, so that the combined radiant energy emitted through the aperture includes the radiant energy of the various wavelengths. The apparatus also includes a control circuit coupled to the sources for establishing output intensity of radiant energy of each of the sources. Control of the intensity of emission of the sources sets the amount of each wavelength of energy in the combined output and thus determines a spectral characteristic of the radiant energy output through the aperture.
