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: LED lighting apparatus including (a) a circuit board which has a plurality of light sources spaced thereon, (b) a heat sink to which the circuit board is thermally coupled, and (c) a securement structure which includes a rigid peripheral structure applying force along a peripheral area of the circuit board toward the heat sink to increase the thermal coupling therebetween to facilitate heat transfer from the light sources during operation. The lighting apparatus may also include an optical member with a plurality of lens portions over corresponding light sources and a peripheral region, the securement structure engaging the peripheral region which sandwiches a gasket against the heat sink. The apparatus may use manipulation involving surface convexity, such as bowing, thereby allowing the securement structure to further facilitate surface-to-surface thermal coupling between the circuit board and the heat sink.
