Abstract
A lamp has an optically transmissive enclosure and a base. At least one LED is located in the enclosure and are operable to emit light when energized through an electrical path from the base. A heat sink comprises a heat dissipating portion having a first part that is located inside of the enclosure and that is thermally coupled to the LED and a second part that is exposed to the ambient environment. The second part comprises a plurality of stems connected to the first part where each stem supports a first overhang that extends over a portion of the enclosure and a second overhang that extends over a portion of the base.
