Patent number: 9627361Abstract: Multiple configuration light emitting diode (LED) devices and methods are disclosed wherein LEDs within the device can be selectively configured for use in higher voltage, or variable voltage, applications. Variable arrangements of LEDs can be configured. Arrangements can include one or more LEDs connected in series, parallel, and/or a combination thereof. A surface over which one or more LEDs may be mounted can comprise one or more electrically and/or thermally isolated portions.Type: GrantFiled: January 31, 2011Date of Patent: April 18, 2017Assignee: Cree, Inc.Inventors: Peter S. Andrews, Raymond Rosado, Michael P. Laughner, David T. Emerson, Jeffrey C. Britt

Patent number: 9515055Abstract: Solid state (e.g., LED) lighting devices include multiple emitters mounted on or over a substrate comprising insulating material with conductive traces thereon, with various emitters being independently controllable with multiple pairs of anodes and cathodes that may be arranged on an opposite surface of the substrate than the emitters. Electrically conductive vias may be defined through the insulating substrate, and a molded lens may be provided over the substrate and emitters mounted thereon. Various combinations of independently controllable emitters or emitter groups may be provided, for example, a red emitter in combination with multiple blue shifted yellow (BSY) emitters, or separately controllable red, green, blue, and white (e.g., BSY) emitters.Type: GrantFiled: May 14, 2012Date of Patent: December 6, 2016Assignee: Cree, Inc.Inventors: Jeffrey Carl Britt, Michael P. Laughner

Patent number: 9041042Abstract: High density multi-chip LED devices are described. Embodiments of the present invention provide high-density, multi-chip LED devices with relatively high efficiency and light output in a compact size. An LED device includes a plurality of interconnected LED chips and an optical element such as a lens. The LED chips may be arranged in two groups, wherein the LED chips within each group are connected in parallel and the groups are connected in series. In some embodiments, the LED device includes a submount, which may be made of ceramic. The submount may include a connection bus and semicircular areas to which chips are bonded. Wire bonds can be connected to the LED chips so that all the wire bonds are disposed on the outside of a group of LED chips to minimize light absorption.Type: GrantFiled: January 31, 2011Date of Patent: May 26, 2015Assignee: Cree, Inc.Inventors: Peter Scott Andrews, Raymond Rosado, Michael P. Laughner, David T. Emerson, Amber C. Abare, Jeffrey C. Britt

Patent number: 6054078Abstract: By employing a unique manufacturing process, unique manufacturing equipment, or a unique combination of materials, a fully integrated, multilayer foamed thermoplastic or elastomeric member or profile having a core member peripherally surrounded by an outer protective layer is attained which is virtually incapable of being removed from said core member. By effectively melting the adjacent surfaces of the foamed layers being interengaged, a core member having any desired cross-sectional shape is produced and is peripherally surrounded with an outer layer integrally bonded thereto. In one aspect of the present invention, metallocene catalyzed plastic material is employed in forming the core member to impart desirable physical attributes thereto.Type: GrantFiled: October 13, 1998Date of Patent: April 25, 2000Assignee: Nomaco, Inc.Inventors: Eduardo Lauer, Michael P.
