An LED area light fixture for street, roadway or large area illumination including upper and lower, elongated, substantially semi-cylindrical, metallic shells spaced from and attached to each other wherein the upper shell is configured from a plurality of elongated, rectangular, angled strips with a plurality of elongated, rectangular PCB strips attached thereto and a plurality of linearly spaced high intensity LEDs embedded in each of the PCB strips and wherein the lower shell has a plurality of openings therein. A plurality of light diffusing lenses and light focusing cones are positioned in alignment with and between the LEDs and openings in the lower shell for providing uniform illumination below the LED light fixture. A heat conductive means is made integral with the PCB strips and the metallic upper shell in order to dissipate the heat generated by the high intensity LEDs during operation of the LED area light fixture.
