Patent ID: 8373195

Claim:
A light-emitting diode structure comprising: a light-emitting diode semiconductor active layer deposited on a substrate enclosed in a casing; a secondary metal plate electrically coupled to a bond pad on the active layer; a primary metal plate electrically and thermally conductively coupled to the substrate via a first metal bonding layer, wherein the primary and secondary metal plates are positioned at an interior bottom surface of the casing and extend laterally through the casing to provide external electrical connections for the light-emitting diode structure; an upper thermal conductivity layer disposed below a bottom surface of the casing; a second metal bonding layer disposed between the upper thermal conductivity layer and a lower thermal conductivity layer; and a dielectric layer for heat conduction interposed between the lower thermal conductivity layer and a heat sink, wherein the heat sink is exposed at a bottom of the light-emitting diode structure.
