6398389, Jun 4, 2002

Filed:

Dec 1, 2000

Appl. No.:

09/728522

Inventors:

Christopher L. Bohler - Allen TX
Frank J. Poradish - Plano TX
Claude E. Tew - Dallas TX

Assignee:

Texas Instruments Incorporated - Dallas TX

International Classification:

F21V 900

US Classification:

362293, 362268, 362242, 362228

Abstract:

In an SLM-type display system, a solid state light source can be used to augment a lamp light source in a least two different ways. First, a solid state source can be used to augment deficiencies in a particular spectral region. Typically, lamps are deficient in red, and a red solid state source would be used. However, the same concept applies to augmenting any color region. Multiple solid state sources could be used to augment more than one region. Second, when the SLM system uses a color wheel, a solid state source can be used to eliminate âspoke lossâ. Multiple solid state sources can be used for providing different colors during the spokes.

Appl. No.:

10/063334

Inventors:

Christopher L. Bohler - North Royalton OH

Assignee:

GELcore, LLC - Valley View OH

International Classification:

F21S 400

US Classification:

362238, 362133, 362249, 362800

Abstract:

A lighting assembly for improving the performance of undercabinet and stream-lined lighting includes a LED module onto which is mounted a plurality of light emitting diodes (LEDs). The LEDs serve as the light source for generating a light pattern. An optical assembly focuses and disperses the LED output to a desired light contour. The lighting assembly further includes a mounting base for attaching the LED module to an associated surface, such as the underside of a cabinet. A battery source is optionally enclosed in the module for providing primary or secondary power to the lighting assembly. In a preferred embodiment, the battery source is a rechargeable battery that can be recharged by means of an AC adapter that connects to the lighting assembly.

US Classification:

362236, 362294, 362373, 362800, 362231

Abstract:

A light module includes a light emitting diode assembly defining a front side light emitting diode array and a rear side. The rear side is in thermal communication with a thermally conductive spreader, and a thermally conductive core is in thermal communication with the conductive spreader. The thermally conductive core includes an electrical conductor in operative communication with the front side light emitting diode array, and a plurality of appendages disposed about the thermally conductive core such that they are in thermal communication with the conductive spreader.

International Classification:

F21V007/04

US Classification:

362604, 362626, 362559, 362812

Abstract:

A lighting apparatus () includes a wave guide () formed from a translucent material. The wave guide has a top surface (), a bottom surface () that has a pre-defined curvature, and at least one side surface () that receives light () injected therein. A plurality of microstructures () is arranged on selected areas of the bottom surface () of the wave guide (). The plurality of microstructures () cooperates with the pre-defined curvature of the bottom surface () to scatter at least a portion of the light () injected into the at least one side surface (). The scattered light () exits the wave guide () through the top surface (). At least one light emitting diode () injects light () into the at least one side surface () of the wave guide (). The scattered light () that exits the wave guide () forms at least one symbol viewable by an associated observer.
