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.
