Patent number: 9599318Abstract: A lighting module is provided. The lighting module includes a flexible substrate having a first side and a second side, a plurality of solid state light sources, and a flexible housing. The first side of the flexible substrate has conductive traces. The plurality of solid state light sources is placed on the first side of the flexible substrate. The plurality of solid state light sources is electrically connected to the conductive traces. The flexible housing has at least a first shape, which may be linear, and a second shape, which may be non-linear. The flexible housing includes a flexible superelastic material in an austenite phase. The flexible housing is placed in proximity to the flexible substrate to form the lighting module.Type: GrantFiled: February 10, 2012Date of Patent: March 21, 2017Assignee: OSRAM SYLVANIA Inc.Inventors: Napoli Oza, Anil Jeswani, Yiming Zhang

Patent number: 9273861Abstract: A thermosyphon light engine and luminaire including the same are provided. The light engine includes a condenser, an evaporation chamber, and a connecting element therebetween. The condenser returns a gaseous substance located therein to a liquid substance. The evaporation chamber includes a solid state light source, a working liquid, and an optical element that beam shapes light emitted by the at least one solid state light source. The solid state light source is immersed in the working liquid, such that heat generated by the solid state light source changes the working liquid into a gaseous substance. The gaseous substance travels through the connecting element to the condenser, which returns the gaseous substance to a liquid substance. The liquid substance then travels through the connecting element back to the evaporation chamber.Type: GrantFiled: November 14, 2013Date of Patent: March 1, 2016Assignee: OSRAM SYLVANIA Inc.Inventors: Camil-Daniel Ghiu, Napoli Oza, Shaun P.

Patent number: 9261267Abstract: A luminaire is providing, having a substrate of a particular shape and a plurality of solid state light sources mounted thereon. The plurality has a measurable characteristic and includes an adjustable solid state light source, such that the characteristic changes in response to adjustment thereof. The luminaire also includes a sensor that detects the characteristic from outputted light, compares it to a baseline value and, based on the comparison, so adjusts the adjustable solid state light source. The luminaire also includes a reflector with a lower edge that conforms to the particular shape of the substrate, and reflects outputted light from the plurality so that it exits past the reflector's upper edge. The luminaire also includes a lightguide having an input that is surrounded by the reflector and captures a portion of the outputted light so as to provide the captured outputted light to the sensor.Type: GrantFiled: April 30, 2012Date of Patent: February 16, 2016Assignee: OSRAM SYLVANIA INC.Inventors: Robert Harrison, Napoli Oza, Ming Li, Ronald Roberts, Anil Jeswani

Patent number: 9212788Abstract: A solid state light source module having a compact, thermally enhanced substrate with one or more recessed pockets, is provided. The module includes a solid state light source and an electrical connection for the solid state light source, such that it is able to receive power so as to generate light. The solid state light source is connected to a substrate having an upper surface and a lower surface. The substrate includes a recessed pocket in the upper surface, defined by a wall and a floor that are at least large enough to accommodate the solid state light source; thus, the solid state light source sits within the recessed pocket. This allows the module to be substantially flat, even with an attached optical system, even utilizing remote phosphor technology, and increases the amount of heat dissipated by a thermal management system that is part of, or connected to, the module.Type: GrantFiled: August 6, 2012Date of Patent: December 15, 2015Assignee: OSRAM SYLVANIA Inc.Inventors: Camil-Daniel Ghiu, Sarah Bazydola, Napoli Oza
