Patent ID: 7284882

Claim:
An LED lighting module assembly, comprising: at least one LED that is operatively connected to a first surface of an LED carrier, said LED carrier having a carrier metallization layer on a second surface; a flexible circuit board comprising a first metallization layer, a dielectric layer and a second metallization layer, the dielectric layer located between the first metallization layer and the second metallization layer, the first metallization layer having defined thereon at least one LED attachment pad, the LED attachment pad having at least one via through the dielectric layer, the via having a via metallization layer which is joined to the first metallization layer and the second metallization layer; a first means for joining the carrier metallization layer to the LED attachment pad, which means is operative to provide a preferred thermal conduction path between the LED and the LED attachment pad; a metal heat sink having a base and a plurality of raised cooling fins extending away from the base, the fins being spaced apart from one another; and a second means for joining a portion of the second metallization which is proximate to the LED attachment pad and the via to the metal heat sink, which means is operative to provide a preferred thermal conduction path between the second metallization layer and the metal heat sink.
