Abstract
An LED light fixture is provided and includes a light engine assembly having a plurality of LED light modules mounted to a printed circuit board. The light engine assembly has a substantially circular periphery. A substantially cylindrical main body portion surrounds the light engine assembly and is sized to define a substantially annular gap between an inner surface of the main body portion and the periphery of the light engine. A plurality of radially extending and circumferentially arrayed fins are positioned rearward of the light engine assembly, and a thermal pad is coupled to and positioned between a rear surface of the light engine assembly and the plurality of fins for transferring heat away from the light engine assembly. The annular gap at least partially defines an air flow path in communication with spaces between the fins. An LED track lighting fixture including the LED light fixture also is provided.
