Patent ID: 7766514

Claim:
A light emitting diode lamp with high heat-dissipation capacity, wherein it comprises: a heat sink unit having a plurality of air-flow channels, a heat absorption end and a heat emitting end, each of said plurality of air-flow channels being defined to have at least two openings opposite to each other for communication with respective regions external to said heat sink unit, the surface of said heat emitting end of said heat sink unit being provided with a micro-structure selected from one of micro-pit, micro-protrusion, porosity and sponge-like opening increasing a surface area thereof, and having a heat radiation layer formed on a surface of said micro-structure; an electrical insulation layer with high heat conductivity laminated on said heat absorption end of said heat sink unit; a metal circuit being created on the electrical insulation layer with high heat conductivity; and at least one light emitting diode packaged on the metal circuit.
