International Classification:

F21V 7/04

US Classification:

362560, 362222

Abstract:

In one embodiment, a solid-state luminaire has a strip of high power LEDs, where each LED emits light into an optical coupler. Light from the optical coupler is then coupled into a light guide. Light coupled into the light guide is mixed and guided to an exit aperture of the light guide. An optical extractor proximate the exit aperture of the light guide redirects light outward, which is optionally redirected generally downward by a secondary reflector that extends outwardly along the length of the light guide. The secondary reflector may be configured to create a variety of light-emission patterns. The luminaire may be hung from a ceiling, in track lighting, used as a pendant or pedestal fixture, or in other applications.

Appl. No.:

12/208077

Inventors:

Chris Lowery - Sunnyvale CA, US
Alex Shaikevitch - Sunnyvale CA, US

International Classification:

H01L 33/00

US Classification:

257 98, 257E33061

Abstract:

An LED assembly can have a plurality of different types of phosphors that are separated from one another in a manner that substantially mitigates the cannibalization of light emitted by at least one of the types of phosphors. By mitigating the cannibalization of light, brighter and more efficient white light LED assemblies can be provided. Such LED assemblies can be suitable for use in such applications as flashlights, displays, and area lighting.

Appl. No.:

13/436166

Assignee:

QUARKSTAR LLC - Las Vegas NV

International Classification:

H01L 33/44
B05C 9/00

US Classification:

257 98, 118620, 438 29, 257E3306

Abstract:

Light-emitting elements such as LEDs are associated with light-converting material such as phosphor and/or other material. A donor substrate comprising the light-converting and/or other material is suitably placed relative to a target substrate associated with the light-emitting elements. A laser or other energy source is then used to transfer the light-converting and/or other material in a pattern via writing or masking from the donor substrate to the target substrate in accordance with the pattern. Addressability and targetability of the transfer process facilitates precise patterning of the target substrate.
