Patent ID: 7947998

Claim:
An LED lamp for producing incoherent visible light comprising: an LED semiconductor structure comprising an n-layer and a p-layer overlying most of the n-layer; first and second terminals; a plurality of spaced metallic conductors on said LED semiconductor structure, each of said metallic conductors having respective neighbouring light-generating portions of the semiconductor structure on opposite sides thereof; wherein each of said plurality of metallic conductors is for energizing an associated underlying portion of said n-layer, said associated underlying portion of each respective metallic conductor being electrically common to respective neighboring light-generating portions of the semiconductor structure that are on opposite sides of the respective metallic conductor; more than one of said plurality of spaced metallic conductors being metallically connected to said first terminal; and wherein a pair of said metallic conductors are spaced apart by a light-generating portion of the semiconductor structure as viewed normal to said layers; and wherein, for each of at least two of said plurality of spaced metallic conductors, p-layer parts of neighboring light-generating portions of the semiconductor structure that are on opposite sides of a respective metallic conductor are interconnected by metal that is over the p-layer, said interconnecting metal being metallically connected to said second terminal.
