20100326492 | Photovoltaic Cell Support Structure Assembly - A plurality of CPV cells are mounted on a common ALOX™ plate. A copper interconnection layer is deposited over an insulating aluminum oxide surface of the ALOX™ plate. The interconnection layer connects all the CPV cells in series, so no wires are needed. In one embodiment, each CPV cell is mounted on a ceramic submount or an ALOX™ submount having an electrically insulating aluminum oxide layer formed in its bottom surface. Vias through the submount couple the cell electrodes to the copper interconnection pattern on the ALOX™ plate. The ALOX™ plate may be the heat sink or may be bolted or soldered to a separate heat sink. In one embodiment, edges of the ALOX™ plate are bent upwards, and side panels are affixed to the ALOX™ plate to create a box that supports a Fresnel lens that directs sunlight to each of the cells (e.g. nine) mounted on the ALOX™ plate. | 12-30-2010 |
20130027915 | Universal Light-Emitting Diode For Light Fixtures - A light-emitting diode (LED) system to retrofit a light fixture has a frame configured to be installed under an existing light fixture and a LED lighting assembly couplable to the frame. In one example, the frame is formed as a plurality of rails having a flange to be installed between the light fixture and a grid member of a ceiling suspension system. The frame may be installed without removal of the existing light fixture. The LED lighting assembly includes an LED array and an optical waveguide for dispersing light from the LED array. The LED system maintains a thin profile, enabling it to retrofit existing light fixtures. Installation time is reduced, thereby reducing labor costs, while the LED lighting provides more light with less energy. | 01-31-2013 |

20140177219 | Low Profile Light Fixture - An ingress protected light-emitting diode (LED) fixture for outdoor and/or indoor use. In one example, a housing includes an acutely angled flange, and a plurality of LEDs fixed to an inside of the acutely angled flange. The LEDs are fixed to the acutely angled flange via a thermal interface to dissipate heat from the LEDs to the housing. An optical reflector is arranged in the housing to reflect light emitted by the LEDs. The optical reflector being customizable and having a shape specific to an application of the LED fixture. The LED fixture maintains a thin profile, making the LED fixture less susceptible to becoming accidently or intentionally damaged when mounted on low ceilings. | 06-26-2014 |
