Abstract
A LED lamp includes an at least partially optically transmissive enclosure and a base. A LED assembly having a plurality of LEDs is located in the enclosure where the LEDs are operable to emit light when energized through an electrical path from the base. A heat sink has 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 at least one LED assembly. The LED assembly is mounted on the heat conducting portion under radial tension. A retention member restrains the LED assembly from moving in an axial direction relative to the heat conducting portion.
