    摘要: An illuminated sign system provides uniform illumination over the lamp face by using partially transmissive lamp masks located between the lamps and the sign face. The sign face itself also diffusely reflects at least a majority of light incident on its second surface back towards the interior of the sign. The lamp spacing ratio in the illuminated signs can be increased, e.g., to a ratio of 3:1 or more, and, possibly, to a ratio of 4:1 or more.

    摘要: The present invention provides perforated film constructions, sign faces including the film constructions, and signs including the sign faces, all of which are capable of having one appearance under light ambient lighting conditions, and another appearance when backlit under dark ambient lighting conditions. The construction is generally planar and includes perforations that occupy, e.g., about 10-35% of the major surfaces of the construction. The perforations are separated by an opaque land area. The back surface of the film construction in the land area (i.e., the surface that is adapted to face the interior of the sign) reflects, e.g., at least about 50% of normal light incident thereon.
