Abstract:
1. An LED area light fixture comprising a first part and a second part wherein said first part has an elongated, metallic, substantially, semi-cylindrical upper shell and an elongated, metallic, substantially, semi-cylindrical lower shell spaced from said upper shell and wherein said second part is a housing attached to said first part, said upper and lower shells being enclosed and attached at opposite ends by end caps, a printed circuit board (PCB) secured to the underside of said upper shell and supporting an array of spaced, high intensity LEDs, said lower shell having a plurality of spaced openings therein wherein each of said plurality of spaced openings is aligned with a respective one of said LEDs, said lower shell having a counter-sunk hole on its inner side at each of said spaced openings, a light diffusing lens within each of said counter-sunk holes, an elongated, substantially semi-cylindrical, inner shell having a plurality of spaced openings therein with a hollow shaped, light focusing cone secured to said inner shell at each of said spaced openings, each of said hollow shaped, light focusing cones being aligned with a respective opening in said semi-cylindrical lower shell and with a respective high intensity LED in said semi-cylindrical upper shell, each of said hollow shaped, light focusing cones having one end with a smaller opening therein which smaller opening encompasses a respective LED in said array and an opposite end with a larger opening therein which opposite end is secured to said inner shell at a respective opening in said inner shell, a heat dissipative conductive layer being integral with said printed circuit board (PCB) and said array of high intensity LEDs, said second part enclosing electronic circuitry for operating and controlling said LEDs, and said second part including means for supporting said light fixture.
