Title: HIGH-OUTPUT LED LIGHT FIXTURE
Abstract:
An LED light fixture (10) including a plurality of heat sinks (62) and a plurality of LED-array modules (61) each engaging an LED-adjacent surface of a corresponding heat-sink base (68) for transfer of heat from each module. The heat sinks have heat-dissipating surfaces extending away from the modules. Each heat-sink base is wider than the module thereon such that the heat-sink base includes a beyond-module portion (681). There is at least one venting aperture (69) through the beyond-module portion of each heat-sink base to provide air ingress to the heat-dissipating surfaces adjacent to the aperture. The inventive light fixture may include a housing and an LED assembly which includes the heat sinks with the 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.
