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.

A lamp comprising:
- An at least partially optically transmissive enclosure;
- a base;
- a LED assembly comprising at least one LED, the LED assembly being located in the enclosure and the at least one LED operable to emit light when energized through an electrical path from the base;
- a heat sink comprising a heat conducting portion that extends in an axial direction and is thermally coupled to the at least one LED assembly, the LED assembly encircling the heat conducting portion;
- and
- a retention member for restraining the LED assembly from moving relative to the heat conducting portion in the axial direction.
