US Patent:

6655825, Dec 2, 2003

Filed:

Dec 28, 2001

Appl. No.:

10/034207

Inventors:

Subramanian Muthu - Ossining NY
Schuurmans Frank J. P. - Valkenswaard, NL
James M. Gaines - Mohegan Lake NY

Assignee:

Koninklijke Philips Electronics N.V. - Eindhoven

International Classification:

F21V 704

US Classification:

362561, 362 31, 362555

Abstract:

A white light is provided for backlighting a liquid crystal display by directing red green and blue light into the first end of a color mixing optical fiber, mixing the red green and blue light in the color mixing fiber to produce white light, and conducting the white light out of the second end of the color mixing fiber to the liquid crystal display. The color mixing optical fiber and sources for generating the red green and blue light may be located remotely from the liquid crystal display, and the white light produced in the color mixing optical fiber coupled to the liquid crystal display by coupling optical fibers, thus simplifying and facilitating construction and operation of the backlighting system, and allowing for more convenient removal of heat remotely from the liquid crystal display.

Appl. No.:

10/179352

Inventors:

James M. Gaines - Mohegan Lake NY, US
Michael D. Pashley - Cortlandt Manor NY, US

Assignee:

Koninklijke Philips Electronics N.V. - Eindhoven

International Classification:

G01J 1/32

US Classification:

250205, 362240

Abstract:

The present invention provides a method, system and structure for maintaining light characteristics from a multi-chip LED package. This may be done by selecting a desired light output and restricting light from a plurality of light emitting diodes in the multi-chip LED package. It may also be done by measuring the restricted light, comparing the measured output light to the desired light and by adjusting current to LEDs in the multi-chip LED package based on the measured light.

Appl. No.:

10/555679

Inventors:

Gert Bruning - Sleepy Hollow NY, US
James Gaines - Mohegan Lake NY, US
Michael Pashley - Cortiandt Manor NY, US

International Classification:

H01L 33/00

US Classification:

257079000

Abstract:

An integrated LED light system () including a printed circuit board () and a submount () mounted on the printed circuit board (). System () further includes an array of LEDs () in electrical communication with the submount () to receive forward currents. The array of LEDs () includes one or more LEDs for emitting one or more color of lights in response to a reception of the forward currents from the submount (). System () additionally includes a heatsink () supporting the printed circuit board () to conduct and dissipate heat away from the printed circuit board (), the submount (), and the LED(s) (). System () further includes a reflector cup () mounted on the printed circuit board () and in optical communication with the LED(s) () to focus the at least one color of light.

Filed:

Jul 21, 1992

Appl. No.:

7/917538

Inventors:

James Matthew Gaines - Mohegan Lake NY
John Petruzzello - Carmel NY

Assignee:

Philips Electronics North America Corporation - New York NY

International Classification:

C30B 2946
C30B 2948
H01L 2106
H01L 2120

US Classification:

438102

Abstract:

Epitaxial layers of II-VI semiconductor compounds having low incidence of lattice defects such as stacking faults are produced by first depositing a fraction of a monolayer of the cation species of the compound, followed by depositing a thin layer of the compound by migration enhanced epitaxy (MEE). Growth of the remainder of the layer by MBE results in much lower defects than if the entire layer had been grown by MBE. Layers are useful in devices such as LEDs and injection lasers.
