Abstract
A lighting system includes a light source, a floor plate with holes and optical fibers one of which is mechanically and optically coupled to one of the holes. The light source includes an enclosure coupled, a light system fixedly coupled to the enclosure, a cylinder, which is hollow and transparent and which has an outer sidewall, concentrically aligned with the light system and rotatably coupled to the enclosure, a plurality of bands of tape, which are transparent, concentrically aligned with the light system and serially disposed on the outer sidewall of the cylinder and a drive system fixedly coupled to the enclosure and mechanically coupled to the cylinder in order to rotate it. The light system generates an output of light. The output of light passes through the outer sidewall. Each optical fiber is optically coupled to the light source at a second end thereof. Either opaque markings or transparent markings, each of which is of a color which is selected from a group of colors, are distributed on the bands of tape.
