Abstract
A rear illuminated light box device for mounting on a surface is disclosed. The device has a support structure comprising support brackets, top and bottom edge frame members, and corner members which hold in place a front translucent sheet material or panel member. The front member can be flexible and stretched in place, or rigid panels. Metal halide lights are used to illuminate the front member. A flat or curved light dispersion member is positioned between the lights and the translucent material to uniformly distribute and disperse the light on the front member. Access members in the apparatus allow convenient changes of the lights.
