Claim 22:
23. A light fixture, comprising:
a heat dissipation structure, the heat dissipation structure formed as a unitary structure and defining:
a first housing member defining first and second sides; and
a plurality of concentric fin sets extending from the first side of the first housing member, first and second sets of an adjacent concentric pair of the plurality of concentric fin sets defining a first open channel therebetween;

a plurality of light emitters thermally coupled to and more proximate to the first set of the plurality of concentric fin sets than the second set of the plurality of concentric fin sets;
a driver circuit thermally coupled to and more proximate to the second set of the plurality of concentric fin sets than the first set of the plurality of concentric fin sets;
a reflector located and formed to redirect light emission to a first direction perpendicular to the first side of the first housing member and away from a second direction perpendicular to the second side of the first housing member;
a second housing member and wherein the reflector is located between the first housing member and the second housing member; and
an optical member, and wherein the optical member spans between the first housing member and the second housing member and provides light emission therethrough.
