Publication number: 20120319616Abstract: A light fixture may include LEDs that each emits light into a particular zone on a lens, where each zone has its own focal properties. Each LED may be grouped into one (or more) subset(s) that corresponds to the zone(s) struck by its emitted light. The LEDs may be selectively electrically controllable, so that the amount of light transmitted through each zone may be controllable by the electrical control system of the fixture. Because light transmitted through different zones emerges from the fixture having different widths, the electrical control system can directly control the amount of light emerging at each width. By mixing relatively narrow light with relatively wide light in the proper proportions, the electrical control system of the fixture may produce light having any desired angular profile between “narrow” and “wide”.Type: ApplicationFiled: June 14, 2011Publication date: December 20, 2012Applicant: OSRAM SYLVANIA INC.Inventors: Michael Quilici, Joseph Allen Olsen

Publication number: 20120287635Abstract: The present disclosure relates to methods for fabricating electrical connectors of a waterproof connector-heat sink assembly of a LED light bar module using injection molding. The methods include matching the coefficient of thermal expansion (CTE) of injection molding materials for the connectors and heat sinks. A heat sink and conductor pins are inserted into an injection mold and the injection molding materials are injected into the injection mold. An integrated connector-heat sink assembly is formed when the injection molding materials of the connectors form a waterproof seal with the heat sink when the injection molding materials solidify. Placement of the heat sink and conductor pins inside the injection mold is controlled to ensure that adhesive bonding between the injection molding materials and the heat sink is stronger than a maximum shear force.Type: ApplicationFiled: July 25, 2012Publication date: November 15, 2012Applicant: TSMC Solid State Lighting Ltd.Inventors: Hsiao-Wen Lee, Chih-Hsuan Sun, Wei-Yu Yeh
