Patent number: 9516723Abstract: A system having an alternating current (AC) driven LED unit, an AC voltage regulator, and a controller is provided. The AC driven LED unit includes a first LED and a second LED coupled in reverse parallel. The AC voltage regulator is operable to receive AC voltage originating from an AC voltage source, regulate the AC voltage according to control signals from the controller, and apply regulated AC voltage to the AC driven LED unit, so as to enable the first LED and the second LED to emit light according to the regulated AC voltage. In addition, a method is provided for driving the LED by regulating the AC voltage. By regulating the AC voltage using the AC voltage regulator, benefits of restraining voltage fluctuations, reducing THD, improving power factor, providing dimming control, and mitigating flicker phenomenon can be achieved.Type: GrantFiled: June 14, 2011Date of Patent: December 6, 2016Assignee: GENERAL ELECTRIC COMPANYInventors: Saijun Mao, Yunfeng Liu, Xiaoming Yuan, Yingqi Zhang, Charles Adrian Becker, Junhui Fei, Jian Wang

Patent number: 7527742Abstract: An etchant including a halogenated salt, such as Cryolite (Na3AlF6) or potassium tetrafluoro borate (KBF4), is provided. The salt may be present in the etchant in an amount sufficient to etch a substrate and may have a melt temperature of greater than about 200 degrees Celsius. A method of wet etching may include contacting an etchant to at least one surface of a support layer of a multi-layer laminate, wherein the support layer may include aluminum oxide; or contacting an etchant to at least one surface of a support layer of a multi-layer laminate, wherein the etchant may include Cryolite (Na3AlF6), potassium tetrafluoro borate (KBF4), or both; and etching at least a portion of the support layer. The method may provide a laminate produced by growing a crystal onto an aluminum oxide support layer, and chemically removing at least a portion of the support layer by wet etch. An electronic device, optical device or combined device including the laminate is provided.Type: GrantFiled: June 27, 2005Date of Patent: May 5, 2009Assignee: Momentive Performance Materials Inc.Inventors: Steven Alfred Tysoe, Steven Francis LeBoeuf, Mark Philip D'Evelyn, Venkat Subramaniam Venkataramani, Vinayak Tilak, Jeffrey Bernard Fortin, Charles Adrian Becker, Stephen Daley Arthur, Samhita Dasgupta, Kanakasabapathi Subramanian, Robert John Wojnarowski, Abasifreke Udo Ebong

Patent number: 7273987Abstract: A flexible interconnect structure allows for rapid dissipation of heat generated from an electrical device that includes light-emitting elements, such as light-emitting diodes (“LEDs”) and/or laser diodes. The flexible interconnect structure comprises: (1) at least one flexible dielectric film on which circuit traces and, optionally, electrical circuit components are formed and at least a portion of which is removed through its thickness; and (2) at least a heat sink attached to one surface of the flexible dielectric film opposite to the surface on which circuit traces are formed. The flexible interconnect structure can include a plurality of such flexible dielectric films, each supporting circuit traces and/or circuit components, and each being attached to another by an electrically insulating layer. Electrical devices or light sources having complex shapes are formed from such flexible interconnect structures and light-emitting elements attached to the heat sinks so to be in thermal contact therewith.Type: GrantFiled: March 21, 2002Date of Patent: September 25, 2007Assignee: General Electric CompanyInventors: Charles Adrian Becker, Stanton Earl Weaver, Thomas Elliot Stecher

Patent number: 5757072Abstract: A protective cap is deposited over the top and sides of an air bridge structure located on an integrated circuit chip. The protective cap provides mechanical strength during the application of a high density interconnect structure over the chips, to prevent deformation of the sensitive (air bridge) structure, and also to prevent any contamination from intruding under the air bridge. More importantly, the protective cap does not impede the performance of the air bridge and therefore does not need to be removed, thereby eliminating the necessity of ablating the HDI structure. Furthermore, the protective cap allows additional area for metallization to provide alternate circuits for coupling, power or ground planes, etc.Type: GrantFiled: June 14, 1996Date of Patent: May 26, 1998Assignee: Martin Marietta CorporationInventors: Bernard Gorowitz, Charles Adrian Becker, Renato Guida, Thomas Bert Gorczyca, James Wilson Rose
