Abstract
An LED lamp having a support with a metal substrate and a center portion with projecting wings. An electrically insulating, thermally conductive circuit is affixed to the substrate; and at least one LED is positioned on each wing with electrically conductive traces connected thereto. The center portion is planar. The wings are bent at multiple angles forming legs, a first angle being greater than 90 degrees, a second angle being normal to the planar center portion. The preferred center portion is pentagonal. The bulb cooperates with a socket that comprises a base; a hollow pedestal extending from the base, the pedestal having a polygonal interior; a thermally conductive, core having an exterior matching the interior; a gap between interior walls of the interior and exterior walls; and a plurality of electrical contacts positioned in the gap for contacting the traces when the bulb is inserted in the socket.
