Abstract:

A high efficiency thermal management system for solid state lighting devices includes an LED heat sink housing formed by a flat bottom wall and a sidewall mounted about its periphery that extends radially outwardly so that the heat sink housing has a frusto-conical shape. Heat-dissipating pin-shaped fins of differing lengths depend from the exterior of the angled wall and from the bottom of the flat bottom wall. The radially inward side of the angled wall has a highly light-reflective surface for collimating light. The base of the device provides a housing for driver electronics. The heat sink housing, the pin-shaped fins, and the base are collectively contoured so that the system has the overall size and shape of a type A light bulb.
