Abstract: A lighting apparatus is provided with a first housing assembly formed from a thermally conductive material and a second housing assembly formed of a thermally conductive material. At least one electrical component is positioned within the first housing assembly and the at least one electrical component is in thermally conductive contact with the first housing assembly. At least one light source is in thermally conductive contact with the second housing assembly. The second housing assembly is not in thermally conductive contact with the first housing assembly, such that thermal energy from the first housing assembly does not directly transfer to the second housing assembly.

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.
