Abstract
An LED lamp may be made with a heat sink optic. The lamp has a base having a first electrical contact and a second electrical contact for receiving current. At least one LED is mounted on a thermally conductive support; that supports electrical connections for the LED and provides thermal conduction of heat from the LED to the optic. The LED support mounted in the base and electrically coupled through the first electrical contact to electrical current. The light transmissive, and heat diffusing optic has an external an internal wall defining a cavity with the LED positioned in the cavity. The optic is in thermal contact with the LED support and mechanically coupled to the base. The snap together structure enables rapid manufacture while allowing numerous variations.
