ABSTRACT:
An illuminated panel is provided for use in a display panel system. The illuminated panel includes a frame having opposed peripheral segments which delimit a predetermined area. A cover piece of a material pervious to light rays is mounted on the front side of the frame and overlies the predetermined area. A collapsible housing adjustable between operative and inoperative modes, is mounted on the back side of the frame and includes a pair of foldable wall sections having first portions connected to first opposed peripheral segments of the frame. When the housing is in the operative mode, second portions of the wall sections extend angularly rearwardly from the frame back side and cooperate to form a cavity for accommodating a removable light source. When the housing is in the inoperative mode, the wall sections are disposed in proximate overlying relation with the cover piece.
