Abstract
An LED light fixture includes a heat dissipation structure defining a first housing member and a plurality of concentric fin sets. A circuit board is thermally coupled to a side of the first housing member opposite the concentric fin sets, a plurality of light emitters is thermally coupled and mounted to a region of the circuit board overlying a first set of concentric fins, and a driver circuit is coupled and mounted to a region of the circuit board overlying a second set of concentric fins. A reflector spans between the circuit board and a second housing member, and a lens spans between the first and second housing member and provides light transmission therethrough.
