Abstract
A rear illuminated fascia apparatus for mounting on a surface is disclosed. The apparatus has a support structure comprising support brackets, top and bottom edge frame members, and corner members which tension and hold in place a flexible, translucent sheet material. Metal halide lights are used to illuminate the sheet material. A light dispersion member is positioned between the lights and the sheet material to uniformly distribute and disperse the light through the sheet material. Access members in the apparatus and access openings in the light dispersion member allow convenient changes of the lights.
