Abstract
A LED lamp comprises an enclosure containing a reflective surface and an optically transmissive exit surface and a base. A LED assembly is mounted on a submount, is located in the enclosure and is operable to emit light when energized through an electrical path from the base. The submount comprises a connector portion having a first electrical contact that is in the electrical path. A first spring contact is electrically coupled to lamp electronics where the lamp electronics and the first spring contact are in the electrical path. A heat sink comprises a heat dissipating portion that is at least partially exposed to the ambient environment and a heat conducting portion that is thermally coupled to the LED assembly. The connector portion is inserted into the heat sink such that the first electrical contact creates an electrical contact coupling with the first spring contact.
