Abstract:
A lamp has an optically transmissive enclosure and a base defining a longitudinal axis of the lamp extending from the base to the free end of the enclosure. A heat sink is at least partially located in the enclosure and includes a tower that extends along the longitudinal axis of the lamp. An LED assembly is positioned in the optically transmissive enclosure. The LED assembly comprises a lead frame circuit or a flex circuit where LEDs are attached to the circuits. The lead frame and flex circuit are formed into a three-dimensional shape and are thermally coupled to the tower.
