Title: Light conductor

Abstract: This light or optical conductor is formed as an integral structure, preferably by extrusion, of an optical material such as glass or transparent plastics material. A light conducting core is supported in an envelope by means of lands and ribs arranged and shaped in such a manner that the core and the lands as well as the ribs are surrounded by hollow spaces which are preferably filled with air. The ribs are tapering away from the core toward the envelope whereby light entering into these ribs through the lands from the core is reflected back into the core.
