Patent ID: 8101966

Claim:
A light-emitting diode structure comprising: a light-emitting diode semiconductor active layer deposited on a metal substrate enclosed in a casing; a secondary metal plate electrically connected to a bond pad on the active layer; a primary metal plate electrically and thermally conductively connected to the metal 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 situated below a bottom surface of the casing; a second metal bonding layer situated between the upper thermal conductivity layer and a lower thermal conductivity layer; and a dielectric layer for heat conduction sandwiched 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.
