LED LAMP AND HEAT SINK

A lamp has an at least partially optically transmissive enclosure and a base that retains lamp electronics. LEDs are located in the enclosure and are operable to emit light when energized through an electrical path from the base. The LEDs are thermally isolated from the lamp electronics in the base....

Beschreibung
Zusammenfassung:	A lamp has an at least partially optically transmissive enclosure and a base that retains lamp electronics. LEDs are located in the enclosure and are operable to emit light when energized through an electrical path from the base. The LEDs are thermally isolated from the lamp electronics in the base. A heat sink is disposed between the base and the enclosure. The heat sink includes a heat conducting portion that is thermally coupled to the LEDs and a heat dissipating portion that is exposed to the ambient environment. The heat dissipating portion includes fins that have inner edges and create spaces between adjacent ones of the fins. The inner edges are spaced from one another to define an interior open space where the interior open space communicates with the spaces between the fins.
