Patent ID: 7598533

Claim:
A high power light emitting diode (LED), comprising: a first porous material layer; a thermal conductive layer disposed on a surface of the first porous material layer; a second porous material layer (a) that is disposed on the thermal conductive layer, on a side thereof opposite the first porous material layer and not in contact with the first porous material layer, to partially cover the thermal conductive layer, and (b) that has an opening defined therein, a chip disposed on the thermal conductive layer within the opening defined in the second porous material layer so that the chip is exposed to contact with air, and an interface layer provided between the second porous material layer and the thermal conductive layer for adhering the second porous material layer and the thermal conductive layer together, wherein the first porous material layer and the second porous material layer are composed of a porous ceramic material, and the interface layer comprises at least one bump.
