Patent ID: 8829774

Claim:
An illumination source comprising: a heat sink comprising an inner core region and an outer core region, wherein: the inner core region comprises a planar region, the outer core region comprises a plurality of structures configured to dissipate heat emanating from the inner core region, and the planar region is disposed toward the center of the heat sink and toward a base of the plurality of structures; an LED assembly comprising: a thermally conductive planar substrate, an LED light source mounted on a top surface of the planar substrate, and a printed circuit bonded to the top surface of the planar substrate, adjacent to the LED light source and electrically connected to the LED light source, wherein a bottom surface of the planar substrate is bonded to the planar region, and the LED assembly generates heat; and a thermally-conductive compound disposed between the bottom surface of the planar substrate and the planar region, the thermally-conductive compound configured to conduct heat from the LED assembly to the inner core region.
