Patent ID: 8390009

Claim:
A package system comprising: a substrate having at least three first thermally conductive structures each extending at least partially through the substrate; at least three second thermally conductive structures each being disposed over, and thermally coupled to, a respective one of the at least three first thermally conductive structures; and at least one light-emitting diode (LED) disposed over and thermally coupled to the at least three first and second thermally conductive structures, wherein the at least one LED includes a P-type layer and an N-type layer, the P-type layer being thermally coupled to a first subset of the at least three first and the at least three second thermally conductive structures, the N-type layer being thermally coupled to a second subset of the at least three first and at least three second thermally conductive structures, wherein at least one of the first subset and the second subset includes a number that is greater than one.
