摘要 |
An improved lighting system for tennis courts, baseball fields and football fields and similar applications is disclosed. Fixed-aim floodlights provide rectangular normally horizontal patterns of illumination. The floodlight lamps are maintained vertically to maintain maximum efficiency. Each floodlight is also provided with a reflector for redirecting light rays from the lamp and a refractor having on its upper part a steep parabolic surface having a reflective metalized surface and prisms for redirecting the reflected light rays laterally. |
