LED LIGHT FIXTURE

摘要

An LED floodlight fixture (100) includes a housing (10) that has at least one end-portion (12), a single-piece extrusion ( 20) including (i) a base (22) having an LED-adjacent surface (220) and an opposite surface (221) and (ii) a heat-dissipating section (24) having heat-dissipating surfaces (241) extending from the opposite surface, and an LED arrangement (30) mounted to the LED-adjacent surface in non-water/air-tight condition with respect to the housing. The housing preferably forms at least one venting gap (14) to provide cool-air (3) ingress to and along the heat-dissipating surfaces by upward flow of heated air (5) therefrom. Additionally and/or alternatively, the base of the single-piece extrusion has one or more venting apertures (28) to provide cool-air ingress for such purpose. One aspect of the invention involves the heat-dissipating section of the extrusion including a wireway (26) therealong enclosing wires extending to/from electrical component(s).
