Abstract
An illuminated sign with an opaque sign plaque employs a light source overlying the sign plaque embraced by a concave downward facing reflector, and a flat lower reflector underlying the sign plaque, providing both direct and reflected illumination over the face of the sign plaque. In its preferred form, the concave reflector is compoundly curved over the ends of the sign plaque and the flat lower reflector is tilted toward the sign plaque.
