Appl. No.:

10/073731

Inventors:

Thomas J. Barnett - Columbus OH
Sean P. Tillinghast - Bexley OH

Assignee:

Weldon Technologies, Inc. - Columbus OH

International Classification:

H01L 2715

US Classification:

257 98, 257 99, 257100

Abstract:

A method and system are taught for a system comprising an LED package. The LED package may comprise an anode, a cathode coupled to the anode, an LED die coupled to the cathode and the anode, a lens coupled to the anode, and a viscous or silicone material located in a cavity defined by the lens, the cathode, and the anode. The viscous or silicone material may be a gel, a grease, a non-resilient material, or a non-liquid material. The method and system may further comprise a mounting device, wherein the lens is mechanically coupled to the mounting device in a socket, bayonet, or screwing like fashion. The method and system may further comprise an anode strip comprising an array of anodes utilized to form an array of the LED packages and a carrier strip comprising receiving devices to receive the array of LED packages. A portion of the lens may either be coated with or comprise light excitable material or the viscous material may comprise light excitable material, such that the system emits white light.

Weldon Technologies, Inc. - Hilliard OH

International Classification:

H01L033/00

US Classification:

257 98, 257 99, 257100

Abstract:

A method and system are taught for a system comprising an LED package. The LED package may comprise a leadframe having an annular contact and a base contact. An LED die may be coupled to the annular and base contacts such that the P-type material portion is electrically connected to an annular contact and the N-type material portion is electrically connected to a base contact. Alternatively the N-type material portion may be electrically connected to the annular contact and the P-type material portion may be electrically connected to the base contact. A lens may be coupled to the leadframe, and an optical material may be located in a cavity defined by the lens, the base contact, and the annular contact. The optical material may be a gel, a grease, a resilient material, a non-resilient material, a rigid material, a liquid material or a non-liquid material. The method and system may further comprise a mounting device, wherein the LED package is mechanically coupled to the mounting device in a socket, bayonet, or threaded fashion.
