Patent number: 9243790Abstract: Techniques and architecture are disclosed for providing a modular lighting system/luminaire having an integrated heat sink assembly. In some cases, the system/luminaire may comprise a plurality of individual modular light sources which have been operatively coupled with one another. In some instances, a modular light source may include one or more light engines (e.g., light emitting diodes or LEDs) which have been operatively coupled with an individual heat sink module. When assembled, the plurality of heat sink modules may define, in the aggregate, a plurality of heat conduits which dissipate thermal energy from the light engines by convective heat transfer. Also, in some cases, the heat sink modules may be electrically isolated from one another, allowing for the heat sink assembly itself, in part or in whole, to function as part of the desired circuit.Type: GrantFiled: November 2, 2012Date of Patent: January 26, 2016Assignee: OSRAM SYLVANIA INC.Inventors: Richard S. Speer, David W. Hamby, Thomas D. Dreeben, Adam M. Scotch, Kenneth G. Grossman

Patent number: 9000598Abstract: The present disclosure is directed to orientation-independent device configuration and assembly. An electronic device may comprise conductive pads arranged concentrically on a surface of the device. The conductive pads on the device may mate with conductive pads in a device location in circuitry. Example conductive pads may include at least a first circular conductive pad and a second ring-shaped conductive pad arranged to concentrically surround the first conductive pad. The concentric arrangement of the conductive pads allows for orientation-independent placement of the device in the circuitry. In particular, the conductive pads of the device will mate correctly with the conductive pads of the circuitry regardless of variability in device orientation. In one embodiment, the device may also be configured for use with fluidic self-assembly (FSA). For example, a device housing may be manufactured with pockets that cause the device to attain neutral buoyancy during manufacture.Type: GrantFiled: September 27, 2013Date of Patent: April 7, 2015Assignee: OSRAM Sylvania Inc.Inventors: David W.

Publication number: 20150062838Abstract: This disclosure is directed to a system for attaching devices to flexible substrates. A device may be coupled to a flexible substrate in a manner that prevents adhesive from contacting conductive ink while the adhesive is harmful. If conductive epoxy is used to anchor conductive pads in the device to the flexible substrate, conductive epoxy may be applied beyond the edge of the device over which conductive ink may be applied to make electrical connections. Holes may also be formed in the flexible substrate allowing conductive epoxy to be exposed on a surface of the flexible substrate opposite to the device location, the conductive ink connections being made on the opposite surface. The conductive ink may also be applied directly to the conductive pads when extended beyond the device's edge. The flexible substrate may be pre-printed with circuit paths, the conductive ink coupling the device to the circuit paths.Type: ApplicationFiled: September 4, 2013Publication date: March 5, 2015Applicant: OSRAM SYLVANIA Inc.Inventors: Richard S.

Patent number: 8937332Abstract: A wavelength converter for an LED is described that comprises a substrate of monocrystalline garnet having a cubic crystal structure, a first lattice parameter and an oriented crystal face. An epitaxial layer is formed directly on the oriented crystal face of the substrate. The layer is comprised of a monocrystalline garnet phosphor having a cubic crystal structure and a second lattice parameter that is different from the first lattice parameter wherein the difference between the first lattice parameter and the second lattice parameter results in a lattice mismatch within a range of ±15%. The strain induced in the phosphor layer by the lattice mismatch shifts the emission of the phosphor to longer wavelengths when a tensile strain is induced and to shorter wavelengths when a compressive strain is induced. Preferably, the wavelength converter is mounted on the light emitting surface of a blue LED to produce an LED light source.Type: GrantFiled: January 31, 2012Date of Patent: January 20, 2015Assignee: OSRAM SYLVANIA Inc.Inventors: Darshan Kundaliya, Madis Raukas, Adam M.
