Appl. No.:

13/806696

Inventors:

Bo Pi - Carlsbad CA, US
Li Xu - Saratoga CA, US

Assignee:

AXLEN, INC. - Wilmington DE

International Classification:

H01L 33/64
H01L 33/62

US Classification:

257 99, 438 26

Abstract:

LED packages and their fabrication techniques are disclosed to provide LED package with improved thermal dissipation based on one or more thermally conductive channels or studs. In one implementation, a LED package includes a plastic body structured to have a hole that penetrates through the plastic body; a metal contact formed on the plastic body at one side of the hole to cover the hole; a LED mounted to the metal contact at a location that spatially overlaps with the hole; and a stud formed in the hole in contact with the metal contact at a first end of the stud and extending to an opening of the hole at a second end of the stud, the stud being formed of a thermally conductive material to transfer heat from the LED through the metal contact and the stud to dissipate the heat at the opening of the hole via the second end of the stud.

Abstract:

Techniques for constructing a solid-state lighting module that includes solid-state light emitters that emit light of different colors and are selected from separated groups of solid-state light emitters that emit light of two or more separated colors, wherein one or more solid-state light emitters are selected from each of the separated color groups of solid-state light emitters. The lighting module includes a programmable device that stores or remembers desirable optical intensities of the separated color groups of solid-state light emitters, and a control circuit that individually controls light intensity of each of the separated color groups of solid-state light emitters. The light control circuit is coupled to or in communication with the programmable device to receive the desirable optical intensities of the separated groups of solid-state light emitters and is operable to adjust the intensities of the separated color groups of solid-state light emitters based on the desirable intensities.
