Sports field lights are designed to project controlled beams of light onto the playing area of an aerial sports ground such as a baseball, soccer, football, cricket, or hockey field. Sports field lighting is served by direct distribution floodlights which can be aimed with a substantial degree of accuracy to provide optimum lighting over a large area. Lighting design for ball fields is extremely challenging since the multi-directional aerial sports are played over an expansive area and involve the critical viewing of a fast moving target (football, baseball, or a puck). A baseball field, which consists of an infield and outfield, covers an area of approximately three acres. An American football playing field is 91.80 meters long and 48.75 meters wide. A soccer field has a width of 59 to 69 meters and a length of 100 to 110 meters. Cricket is played on an oval or circular shaped field in size from about 80 to 150 meters across. The ball may travel at speeds over 219 km/hr (baseball) and is in the air at least part of the time. An appropriate luminous environment is critical to the visibility of the playing target for players, spectators, referees, and in some occasions broadcast cameras.
