摘要： In one embodiment of a solar concentrator, a tailored aspheric lens augments the solar-concentrator performance of a concave mirror, widening its acceptance angle for easier solar tracking, making it more cost-competitive for ultra-large arrays. The molded-glass secondary lens also includes a short rod for reducing the peak concentration on a photovoltaic cell that is optically bonded to the end of the rod. The Simultaneous Multiple Surface method produces lens shapes suitable for a variety of medium and high concentrations by mirrored dishes. Besides the rotationally symmetric parabolic mirror itself, other aspheric deviations therefrom are described, including a free-form rectangular mirror that has its focal region at its edge.

摘要： A luminaire has a light source and a shell integrator. The shell integrator has a transparent dome over the light source, with inner and outer surfaces formed as arrays of lenslets. Each lenslet of the inner surface images the light source onto a respective lenslet of the outer surface, and each lenslet of the outer surface images the respective lenslet of the inner surface as a virtual image onto the light source. The dome may be substantially hemispherical. The light source and the integrator may be at an input of a collimator.

摘要： An optoelectronic cooling system is equally applicable to an LED collimator or a photovoltaic solar concentrator. A transparent fluid conveys heat from the optoelectronic chip to a hollow cover over the system aperture. The cooling system can keep a solar concentrator chip at the same temperature as found for a one-sun flat-plate solar cell. Natural convection or forced circulation can operate to convey heat from the chip to the cover.

摘要： A tubular luminaire efficiently utilizes the light of a line of high-brightness unlensed LEDs to reproduce the homogeneous appearance of a neon tube. The transparent tube has an annular cross-section suitable for cost-effective manufacturing by extrusion. The LEDs are mounted in a line on a circuit board that can be positioned either inside or outside the tube. Their light shines into a cylindrical groove, thereby entering within the material of the tube. Above the groove, the wall of the tube has a spiral shape that reflects the light laterally so that it stays within the annular tube for a considerable path length. Volume scattering by a low density of scattering inclusions causes the light to escape as a homogenous glow. Alternatively, mild surface scattering from the inside surface can be used.
