LED lamp
First Claim
1. A lamp comprising:
- a housing containing a reflector;
a base;
an LED assembly comprising at least one LED located in the housing and operable to emit light when energized through an electrical path from the base;
a heat sink comprising 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, the heat sink being connected to the base by a snap fit connector comprising a deformable first member on one of the base or heat sink engaging a second member on the other one of the heat sink and the base; and
a retention member mounted on the heat sink that holds the first member in engagement with the second member.

Abstract
A LED lamp includes an at least partially optically transmissive enclosure and a base. A LED assembly comprising at least one LED is located in the enclosure and is operable to emit light when energized through an electrical path from the base. 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 at least one LED. The heat sink is connected to the base by a snap fit connector comprising a deformable first member on one of the base or heat sink engaging a second member on the other one of the heat sink and the base. A retention member holds the first member in engagement with the second member. A seal is positioned between the heat sink and the base, the seal being compressed between the heat sink and the base.
