Patent ID: 7170151

Claim:
An LED assembly, comprising: a substrate comprising a first top surface that is solder wettable; a heat sink comprising a flange and a body protruding above the flange, the flange comprising a first bottom surface that is raised below the flange and solder wettable, the body comprising a second top surface that is raised above the body and solder wettable, the first bottom surface having substantially the same shape and area as the first top surface of the substrate, the heat sink being mounted atop the substrate by a first solder between the first bottom surface and the first top surface; a submount comprising a second bottom surface that is solder wettable, the second bottom surface having substantially the same shape and area as the second top surface of the heat sink, the submount being mounted atop the heat sink by a second solder between the second bottom surface and the second top surface; an LED die mounted atop the submount; an insulating body defining a cavity for receiving the heat sink; metal leads attached to the insulating body; and bond wires coupling the submount to the metal leads.
