Abstract:

A light engine is provided including a thermally conductive housing including a generally cylindrical wall defining a cavity, the cylindrical wall includes an inner surface and an outer surface, a plurality of ducted passageways being axially disposed on the outer surface, a light module including at least one light emitting diode (LED) for producing visible light, the light module coupled to a first end of the housing, wherein heat generated by the at least one LED is conducted to the housing, and a current driver circuit arranged on a substrate, the substrate configured to be disposed in the cavity of the housing and electrically coupled to the light module for providing current to the at least one LED. The ducted passageways aid in convective heat dissipation through a “chimney” type of affect.
