Abstract: A lamp is located in a housing which has a top wall formed of a sheet of light-conducting material, silvered on its internal surface, and having a light emitting hole for internally illuminating a transparent object d'art placed thereon. Light striking the edge of the hole is transmitted by the sheet to the beveled perimetral edges of the top where the conducted light is emitted. One side wall has an opening which provides an edge for receiving light which is emitted from the side wall perimeter.
