Abstract: An LED light fixture including a housing portion and a base together defining an open space therebetween permitting air/water-flow therethrough. The housing portion forms a chamber enclosing at least one driver. The base extends from the housing portion and supports at least one LED illuminator outside the chamber. The housing portion and the base may each be formed as part of a one piece with the open space along at least three sides of the base. Alternatively, the base may be a separate structure secured with respect to the housing. Such base may be a single-piece extrusion supporting a plurality of LED modules or comprise a plurality of extruded heat sinks. Each heat sink may support one or more LED modules.

Abstract: An LED light fixture including a frame defining a forward open region and a rearward region with a rearmost portion adapted for securement to a support member. An LED assembly is secured with respect to the frame and positioned within the open forward region with open spaces remaining therebetween. The LED assembly includes an LED illuminator secured with respect to the LED-supporting region of a heat sink with an LED-supporting region and heat-dissipating surfaces extending therefrom. Another aspect of the invention is a non-metallic frame defining a forward open region and having a rearward region having a rearmost portion adapted for securement to a support member. An LED assembly is secured with respect to the frame and positioned within the open forward region with open spaces remaining therebetween.
