- a. a plurality of LED light sources forming arrays of LED light sources, wherein the LED light sources are distributed at the sports venue and directed at the playing area, wherein the arrays of LED light sources are contained in luminaires that, for a viewing direction, produce key light, back light, or fill light, and wherein, when no back light is produced, a luminous flux provided by the luminaires that produce fill light is less than or equal to about 60% of a luminous flux provided by the luminaires that produce key light, and when both key light and back light are produced, a luminous flux provided by the luminaires that produce fill light is also less than or equal to about 40% of a combined luminous flux provided by the luminaires that produce key light and the luminaires that produce back light;
b. a plurality of optics mounted relative to the arrays of LED light sources, each optic adapted to control one or more light sources to produce one or more beam types to illuminate the playing area, wherein the beam types are selected from the group consisting of NEMA Types 0, 1, 2, 3, 4, and 5; and
c. a plurality of mounts to position the light sources and the optics, wherein the mounts allow the light sources to direct light to the playing area;
wherein distribution of the luminaires provides modeling for at least a portion of the playing area.
