Filed:

Mar 13, 2007

Appl. No.:

11/717122

Inventors:

Steve S. Lyons - Herndon VA, US
Matthew H. Aldrich - Arlington VA, US

Assignee:

Renaissance Lighting, Inc. - Herndon VA

International Classification:

F21V 9/00

US Classification:

250205, 250228, 362227, 362231, 362236, 362240

Abstract:

A solid state lighting system controls overall light output level in a step-wise manner by discretely controlling the ON/OFF state of its light emitters. Solid state emitters that are ON at a given time are set and kept at a level intended to produce a desired output characteristic, e. g. at a level to produce a described color of light. The system utilizes optical processing of the generated light, for example by diffuse reflection in an optical integrating cavity, sufficient to convert the point source output(s) from the emitting elements into a uniform virtual source output. The virtual source output appears uniform regardless of how many emitters are ON or OFF, and only the perceptible intensity of the light output changes with the number of emitters that the system has ON.

Assignee:

ABL IP Holding LLC - Conyers GA

International Classification:

F21V 29/00

US Classification:

362294, 362218, 362373, 362649, 362646

Abstract:

A lamp, for general lighting applications, utilizes solid state light emitting sources to produce and distribute white light. The exemplary lamp also includes elements to dissipate the heat generated by the solid state light emitting sources. The lamp includes a thermal handling system having a heat sink and a thermal core made of a thermally conductive material to dissipate the heat generated by the solid state light emitting sources to a point outside the lamp.

Filed:

Jun 14, 2006

Appl. No.:

11/452280

Inventors:

Steve Lyons - Herndon VA, US
Matthew Aldrich - Arlington VA, US
Jack Rains - Oak Hill VA, US

International Classification:

G01J 1/00

US Classification:

250228000

Abstract:

An exemplary system to provide visible lighting of a selectable spectral characteristic (e.g. a selectable color combination of light) uses an optical integrating cavity or other diffuse mixing element to combine light of different colors from different color LEDs. Amplitude modulation of pulsed operation the light sources, e.g. pulse amplitude modulation added to a baseline forward bias current for each of the LEDs, controls the amount of each light color supplied to the diffuse mixing element and thus the amount included in the combined light output of the system. A color sensor may provide feedback as to a color characteristic of the combined light, for closed-loop control of one or more of the pulse amplitude modulations. Examples are also disclosed that utilize phosphor doping of one or more of the system's reflective elements, to add desired wavelengths of light to the combined output.

Alan W. Geishecker - Woodbridge VA, US

International Classification:

G06Q 90/00

US Classification:

705 1, 257798

Abstract:

Techniques are disclosed to monitor the time of operation of a solid state lighting system, e.g. for warranty purposes. Examples are disclosed that measure time of system connection to power and/or time of light output from the solid state emitter(s) of the system. A service under the warranty is provided if operation time does not exceed the warranty eligibility criteria, e.g. maximum limit(s). The service provided under the warranty may be pro-rated based on the time of operation.

International Classification:

G02B 26/00

Abstract:

The examples herein relate to assembly techniques and structures for sealing and lateral pressure compensation techniques that can be utilized in, for example, an electrowetting cell. The electrowetting cell can include a substrate that supports a well filled with a liquid. The electrowetting cell can include a control channel electrode to control the liquid via an electric field and a circuit connection to drive the control channel electrode. A seal is coupled to a spacer to seal the well between the substrate and the transparent cover. An expansion space, exterior to the well, is formed with the coupling of the seal and the spacer. As the liquid or the gas thermally expands or contracts, the seal compensates laterally by deforming sideways in an empty space of the expansion space.
