  • Frontal illumination of a surface using LED lighting
    Patent number: 7896522
    Abstract: A plurality of lamp arrays (30A-30N) provide uniform lighting across the copy area of a billboard sign. The arrays (30) are arranged end-to-end horizontally along the length of the copy area. Each array (30) comprises a plurality of LEDs (34A-34N) and a plurality of lenses (36A-36M). The various lenses (36) direct and focus the light from the LEDs (34) at the various parts of the copy area so as to minimize dark and light spots. A “TOP” set of LEDs preferably illuminates the top part of the copy area, a “MIDDLE” set of LEDs preferably illuminates the middle of the copy area, and “FILLER” LEDs preferably serve to illuminate the bottom of the copy area. The lamp arrays are preferably mounted to a catwalk (14) at the bottom of the billboard.
