发明名称 Lighting system for playing fields
摘要 The illumination system includes a plurality of illumination structures (10), the illumination structures being arranged around the periphery of the playing field. Each illumination structure (10) includes a mounting pole (12) and a plurality of luminaires which are individually mounted by mounting arms from the pole. The luminaires are cut-off forward-throw luminaires. The luminaires are arranged relative to each other such that each luminaire, respectively, does not block light originating from any of the other luminaires.
