20120312351 | Efficient solar energy concentrator with improved thermal management - A solar concentrator comprises a reflective curved mirror assembly, a support riser placed to support and position photovoltaic cells attached to a printed circuit board that is in turn attached to a heat sink at the focal point of the mirrors of the reflective curved mirror assembly. A central support riser may grasp the assembly of photovoltaic cells attached to a printed circuit board while other support risers may allow the assembly of photovoltaic cells to move slightly to accommodate differences in the coefficient of thermal expansion between the mirror assembly and the printed circuit board and the heat sink. The solar concentrator may include a prism assembly placed to separate solar radiation angularly by wavelength to facilitate use of single junction photovoltaic cells for increased efficiency. The heat sink may form the major structural element of the solar concentrator. | 12-13-2012 |
20120024374 | Solar energy concentrator - A solar concentrator assembly comprises a segmented wave-guide assembly, a reflective mirror assembly, and an optical target-providing unit. A segmented waveguide assembly comprises a plurality of wave-guide segments, each segment comprising a set of surfaces disposed so as to support TIR propagation of solar energy and a turn mirror affixed thereto and disposed to receive solar energy from a mirror of the reflective mirror assembly and reflect said solar energy into the wave-guide segment at angles compatible with TIR propagation. The reflective mirror assembly comprises a plurality of mirrors each being aligned to reflect the solar energy to a turn mirror affixed to each wave-guide segment. The optical target providing unit converts solar energy from the light propagated in the wave-guide assembly to a different form of energy. | 02-02-2012 |
20100108124 | SOLAR ENERGY CONCENTRATOR - A solar concentrator assembly comprises a stepped wave-guide assembly, a reflective mirror assembly, and an optical target providing unit. The stepped wave-guide assembly includes at least one surface, comprising a set of parallel but offset adjacent surfaces, and an opposing surface. The wave-guide assembly propagates light in a total internal reflection mode between the at least one surface and the opposing surface. The wave-guide assembly also includes transition surfaces between the adjacent parallel surfaces and the transition surfaces include edges perpendicular to a longitudinal axis of the wave-guide assembly. The reflective mirror assembly includes a plurality of mirrors each being aligned to reflect the light to one of the transition surfaces between two of the parallel adjacent surfaces. The optical target providing unit converts solar energy from the light propagated in the wave-guide assembly to a different form of energy. | 05-06-2010 |
