Patent ID: 8079735

Claim:
An illumination device, comprising: a housing configured to form a base for the illumination device; a substrate set into the housing; and a plurality of light emitting diodes mounted on the substrate, each light emitting diode of the plurality having a pair of elongated leads that support the light emitting diode on the substrate, wherein one light emitting diode of the plurality is mounted at a center point on the substrate and the remaining light emitting diodes of the plurality are arranged in two concentric circles centered on the center point, the two concentric circles forming an inner circle and an outer circle, and wherein the one light emitting diode mounted at the center point is spaced a first distance from the substrate, the light emitting diodes mounted in the inner circle are spaced a second distance from the substrate and the light emitting diodes mounted in the outer circle are spaced a third distance from the substrate, whereby the distances spacing the light emitting diodes of the plurality from the substrate enable cooler operation of the light emitting diodes of the plurality in the illumination device.
