ABSTRACT:
The lighted sign enclosure has a transparent, or translucent hollow body, reaching down from the ceiling, and inside the body a U-shaped fluorescent light tube, extending essentially as far down as the hollow body and back up. The body has a top rim, held on a grid of T-bars or similar bars of the ceiling. It is normally used as a sign, and offers a unique way of displaying symbols, especially pictures.
