ABSTRACT:
An illuminating apparatus has a transparent or semitransparent optical medium in the form of an acrylic plate, two fluorescent tubes for emitting light into the acrylic plate through opposite end surfaces thereof, and a reflecting plate disposed under a lower surface of the acrylic plate for upwardly reflecting the light. The lower surface of the acrylic plate defines a diffusing plane including a plurality of irregular reflector regions distributed thereon. The irregular reflector regions comprise ship-shape patterns arranged in juxtaposition longitudinally of the fluorescent tubes. The diffusing plane further includes modified irregular reflector regions formed where the irregular reflector regions are absent. The modified irregular reflector regions irregularly reflect a less quantity of light than the irregular reflector regions.
