LED LAMP

摘要

A lamp has an optically transmissive enclosure (112) and a base (102) defining a longitudinal axis of the lamp extending from the base (102) to the free end of the enclosure. A heat sink (149) is at least partially located in the enclosure and includes a tower (152) that extends along the longitudinal axis of the lamp. An LED assembly (130) is positioned in in the optically transmissive enclosure. The LED assembly (130) comprises a lead frame circuit or a flex circuit where LEDs (127) 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 (152).
