20090252950 | ALUMINA SUBSTRATE AND METHOD OF MAKING AN ALUMINA SUBSTRATE - An alumina substrate and method of making an alumina substrate using oxidation is provided. Generally, photoresist masks are used to protect selected areas of an aluminum layer. The unprotected or exposed areas of the aluminum layer are then oxidized during a photolithography process. The protected, unexposed areas of the aluminum layer retain their conductive properties while the oxidized areas are converted to alumina, or aluminum oxide, which is non-conductive. Accordingly, an alumina substrate having conductive areas of aluminum is formed. In one embodiment, the alumina substrate includes an alumina layer, one or more aluminum vias formed within the alumina layer, each of the one or more aluminum vias extending between the bottom of the alumina layer and the top of the alumina layer, wherein the one or more aluminum vias are integrally formed within the alumina layer. | 10-08-2009 |
20100027274 | OPTICAL REFLECTOR - An optical reflector for emitting light generated from a light source, such as a light emitting diode. According to one embodiment, the optical reflector includes a plurality of panels forming a cavity, the cavity having a light receiving end and a light output end, the inner side of the cavity having a reflective surface, and wherein the cavity has a plurality of stepped layers along the inner surface of the cavity extending from the light receiving to the light output end; and wherein the light receiving end is configured to receive the light generated from the light source, and the stepped layers of the cavity are configured to reflect the light generated from the light source and emit the reflected light from the light output end in an asymmetrical distribution. Embodiments of present invention use a trapezoidal shape to create the asymmetrical output distribution. | 02-04-2010 |
