Patent ID: 8053969

Claim:
An LED package structure for increasing light-emitting efficiency, comprising: a heat-dissipating unit having at least one heat-dissipating substrate; an insulating unit having at least one insulating layer formed on the at least one heat-dissipating substrate and at least one receiving groove passing through the at least one insulating layer and formed above the at least one heat-dissipating substrate, wherein the at least one insulating layer has a top surface on a top side thereof and an inner surface, and the inner surface of the at least one insulating layer is an annular inclined surface in the at least one receiving groove; a light-emitting unit having at least one light-emitting element received in the at least one receiving groove and disposed on the at least one heat-dissipating substrate; and a conductive unit having at least two conductive structures disposed on the at least one insulating layer and separated from each other, wherein the at least one light-emitting element has two electrodes respectively electrically connected to the at least two conductive structures via two conductive wires.
