Claim:
1. A LED lamp comprising: a base; an at least partially optically transmissive enclosure connected to the base defining a longitudinal axis of the lamp extending from the base to the enclosure; a frame comprising a first end connected to the base and a second end connected to the enclosure, the frame narrowing from the second end to the first end and comprising openings for allowing access to the interior of the enclosure; a heat sink partially disposed in the enclosure and supporting a plurality of LEDs operable to emit light when energized where the interior of the enclosure is exposed to the ambient environment, the heat sink comprising a plurality of separate heat sink structures that are mounted to the lamp independently of one another, wherein each of the plurality of heat sink structures comprises a mounting portion positioned in the enclosure for supporting the LEDs and a heat dissipating portion located outside of the enclosure and exposed to the ambient environment, the mounting portion comprising a first mounting surface supporting at least one first LED of the plurality of LEDs and a second mounting surface supporting at least one second LED of the plurality of LEDs, the first mounting surface being disposed parallel to the longitudinal axis of the lamp and and a second end spaced from the first mounting surface, the second mounting surface extending away from the longitudinal axis from the first end to the second end such that the second mounting surface is disposed at an included angle with the first mounting surface of less than 180 degrees where the second end of the second mounting surface extends from the longitudinal axis a first distance and the heat dissipating portion extends from adjacent the second end of the second mounting surface to the first end where the first end extends from the longitudinal axis a second distance where the first distance is greater than the second distance such that the heat dissipating portion narrows as the heat dissipating portion extends from the second mounting surface to the first end, the heat dissipating portion being at least partially disposed in the openings and extending from the first end to the second end.
