As a result, the single body becomes multi-functional. Channels may be cast into the single piece body to allow for heat pipes to be press fit. Several locations on the body may include tapped holes to attach mounting hardware (lens retainer), visors, power supply, and LED array printed circuit board. The body includes a cavity to receive a reflector. The reflector may be a single unit or segmented. The cavity may alternatively be coated with reflective material. The body incudes heat fins which extend from the back of the fixture and transition forward around the reflector cavity toward a front opening. ## Claims ### Claim 1 A sports light fixture for projecting light, comprising: a single cast body having an outer dimension and including a plurality of fins on said outer dimension; said single cast body having a back and a front; a lens secured directly to said body in a weather tight manner through which the light is projected; said light is projected in a focused beam having a beam angle of less than 70 degrees; said body including a reflector cavity to receive an LED printed circuit board; said LED printed circuit board including an LED array having an input power of at least 250 watts; a frusto-parabolic reflector secured in said reflector cavity and adapted to shape the projected light; a power supply secured to said body; said power supply in electrical communication with said LED printed circuit board; a plurality of said plurality of fins extend from said back of said body adjacent said LED printed circuit board to said front of said body adjacent said lens. ### Claim 2 (depends on 1) The sports light of claim 1 wherein said lens is secured to said front of said body covering said reflector cavity. ### Claim 3 A sports light, comprising: a single cast body having an outer dimension and including a plurality of fins on said outer dimension; said single cast body including a back, a front opening, and an internal cavity; said single cast body including a means for mounting; said internal cavity configured to receive an LED printed circuit board having an input power of at least 250 watts; said LED printed circuit board capable of projecting light through said front opening; said light being projected in a focused beam having a beam angle of less than 70 degrees; said internal cavity including a frusto-parabolic reflector adapted for shaping and directing said light through said front opening; said front opening including a surface adapted to receive a weather proof gasket; a lens secured to said body adjacent said weather proof gasket, said lens covering said front opening; a power supply in electrical communication with said LED printed circuit board; said single cast body adapted such that said body in cooperation with said weather proof gasket and said lens renders said internal cavity weather tight. ### Claim 4 (depends on 3) The sports light of claim 3 wherein said lens is secured to said body by a retainer ring. ### Claim 5 (depends on 3) The sports light of claim 3 wherein said LED printed circuit board includes an RGBW LED array. ### Claim 6 (depends on 3) The sports light of claim 3 wherein said reflector is comprised of a plurality of reflector segments. ### Claim 7 (depends on 3) The sports light of claim 3 including at least one visor secured to said body. ### Claim 8 (depends on 3) The sports light of claim 3 wherein said printed circuit board is a chip-on-board printed circuit board. ### Claim 9 (depends on 3) The sports light of claim 3 wherein said power supply is secured in said internal cavity. ### Claim 10 (depends on 3) The sports light of claim 3 wherein said single cast body includes at least one feed through port; said at least one feed through port adapted to being sealed in a weather tight manner. ### Claim 11 (depends on 10) The sports light of claim 10 wherein electrical wiring suitable for providing electrical communication between said power supply and said LED printed circuit board is inserted through said at least one feed through port. ### Claim 12 (depends on 11) The sports light of claim 11 wherein said power supply is secured to said back of said single cast body. ### Claim 13 (depends on 3) The sports light of claim 3 wherein said power supply is remote from said single cast body. ### Claim 14 (depends on 3) The sports light of claim 3 wherein said LED printed circuit board is secured in said internal cavity adjacent said back of said single cast body such that said plurality of fins are located between said LED printed circuit board and said front opening of said single cast body. ### Claim 15 (depends on 3) The sports light of claim 3 wherein said mounting means is a knuckle mount. ### Claim 16 (depends on 3) The sports light of claim 3 wherein said mounting means is a pendant mount. ### Claim 17 (depends on 4) The sports light of claim 4 wherein said LED printed circuit board is adapted for being computer controlled. ### Claim 18 (depends on 17) The sports light of claim 17 wherein said power supply is adapted for dimming said LED array. ### Claim 19 (depends on 18) The sports light of claim 18 wherein said LED printed circuit board includes multiple LED arrays each on a separate channel such that each LED array is capable of being dimmed independently by said power supply. ### Claim 20 (depends on 18) The sports light fixture of claim 18 adapted for being controlled via DMX. ### Claim 21 (depends on 3) The sports light fixture of claim 3 wherein said LED printed circuit board includes an RGB LED array.
