    Abstract: An LED floodlight fixture LED light fixture including a plurality of heat-sink-mounted LED-array modules, each module engaging an LED-adjacent surface of a heat-sink base for transfer of heat from the module, and at least one venting aperture through the heat-sink base to provide air ingress to the heat-dissipating surfaces adjacent to the aperture. The LED light fixture may include a plurality of heat sinks, each heat sink with its own heat-dissipating surfaces and heat-sink base which has one of the LED-array modules engaged thereon. The heat-sink base is wider than the module thereon such that the heat-sink base includes a beyond-module portion. The venting aperture(s) is/are through the beyond-module portion of the heat-sink base. The inventive light fixture may include a housing and an LED assembly which includes the heat-sink-mounted LED-array modules. The LED assembly and the housing form a venting gap therebetween to provide air ingress along the heat-sink base to the heat-dissipating surfaces.

    Abstract: An LED light fixture includes a heat-sink body having a circuit-board mounting surface and a circuit board in thermal-contact relationship to the circuit-board mounting surface. The circuit board has an LED-populated area and a surrounding non-LED-populated area such that lateral heat conduction within the circuit board is greater than heat conduction from the circuit board to the circuit-board mounting surface. The fixture may be a low-profile LED light fixture including a base plate which has a substantially planar back surface, a front surface and heat-dissipating surfaces extending forward from the front surface. An LED circuit board and at least one LED power-circuitry unit, which are secured with respect to the front surface adjacent to the heat-dissipating surfaces, do not extend behind the back surface of the base plate.

    Abstract: An LED light fixture including a heat-sink body having a circuit-board mounting surface and an aperture member supported over the circuit-board mounting surface and forming an optical aperture. An LED circuit board is affixed in thermal-contact relationship to the circuit-board mounting surface in position between the mounting surface and the aperture member, the circuit board having an LED-populated area and a surrounding non-LED-populated area which extends beyond the optical aperture. In some other embodiments, the fixture is a low-profile LED light fixture including a cover and a base plate which has a substantially planar back surface, a front surface and heat-dissipating surfaces extending forward from the front surface. An LED circuit board and at least one LED power-circuitry unit, which are secured with respect to the front surface along side the heat-dissipating surfaces, do not extend behind the back surface of the base plate. The aspect ratio of the cross-section of the fixture orthogonal to the base plate between the back surface of the base plate and a forwardmost surface of the cover is greater than about 6.
