ABSTRACT:
A flexible sign face has uniform luminosity. The sign includes an elongated enclosure having a rear wall and a flexible face translucent front wall, spaced from the rear wall. A plurality of point sources of light are spaced along the rear wall between the front and rear walls. A reflector is provided between each pair of adjacent point sources for reflecting light received from each adjacent point source, toward the flexible face. A diffusion panel is in front of each point source, and between each point source and the front wall. The diffusion panel has perforations in a pattern which increase in density from a center of the panel outwardly toward edges of the panel. The panel also includes a metal corrugated portion carrying the perforations and a translucent acrylic portion attached to the corrugated portion.
