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

Publication number: 20150369658Abstract: The present disclosure is directed to a light assembly employing uncharacterized light sources. An example device may comprise at least one light source, a memory and at least one interface. Light emitted by the at least one light source may be tested. Configuration data based on results of the testing may be stored in the memory. The above device may then be used in other assemblies. For example, a system may be assembled including at least one of the device and a power supply. The power supply may be able to read the configuration data from the memory and configure itself based on the configuration data. For example, to generate light with certain characteristics the power supply may use the configuration data to determine at least one drive current to cause the at least one device to emit light having the desired characteristics.Type: ApplicationFiled: June 18, 2014Publication date: December 24, 2015Applicant: OSRAM SYLVANIA Inc.Inventors: John H.

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. Hamby, Adam M. Scotch, Sridharan Venk, Alan Lenef

Publication number: 20100078151Abstract: A heat pipe for transporting heat from light emitting elements includes a sealed body made of a non-porous ceramic, a vapor channel inside the body that extends between two heat transfer locations spaced apart on an exterior surface of the body, a ceramic wick inside the body that extends between the two heat transfer locations, and a working fluid that partially fills the vapor transport channel. In a method of making this heat pipe, the body and wick are desirably formed together as a seamless monolithic structure made of the same ceramic material. Using a ceramic makes the heat pipe corrosion resistant and allows electrical components like LEDs to be mounted directly on the body because the ceramic is a dielectric.Type: ApplicationFiled: September 30, 2008Publication date: April 1, 2010Applicant: OSRAM SYLVANIA INC.Inventors: William D.
