Abstract: A sports lighting fixture including a single cast body which combines the functions of the base, heatsink, reflector housing, and interconnection gaskets, with many cast female holes that are later tapped with threads to eliminate the need for any nuts as fasteners. 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.

Abstract: A light fixture apparatus with at least one multi-color light emitting diode (LED) cluster. Each LED cluster preferably includes four differently colored LEDs, or four different color-correlated temperature LEDs, in a single optic defining a foursquare array. A cluster thus arranged thereby promotes thorough mixing of the differing wavelengths of light emitted by the cluster. Further, a plurality of such clusters may be arranged so to enhance or optimize color mixing amongst the plurality of clusters. A series of LED clusters may be situated linearly along a suitable substrate in a luminaire for emitting visible light.
