The improved heat sink system for a lighting fixture includes a conductive mount configured to selectively receive and retain a lighting subassembly. An inner heat sink couples to the conductive mount and is positioned to encompass the lighting assembly. A plurality of cooling fins couple to and extend away from the inner heat sink. An outer heat sink couples to the cooling fins and is offset from the inner heat sink to permit air flow therebetween and over the cooling fins. This enables air convection cooling of the inner heat sink, the outer heat sink and the cooling fins simultaneously to draw heat energy away from the lighting subassembly. |
