Abstract
Lamp shades are provided with ornamentation utilizing light pipes and fiber optics, using light pipe technology to provide an ornamented shade. For lampshades of the truncated conical shape type, this light pipe ornamentation includes light emitting top and/or bottom circular rims, as well as an optional light emitting central thematic character/logo figure in 3D relief. Light is transmitted from the interior of the shade to illuminate the light pipe features, or from fiber optic electrically conductive wires/cables, which may include circular light pipes attached as integrally formed top and bottom rims of the lamp shade. Alternatively, the circular decorative light pipes may be formed by a plurality of arcuate segments, which, when joined together, form a circular rim, where light may be diffused and sent through the segments. The translucent light pipe elements may be injection molded of tinted light guide grade plastic resin.
