Lampshade

Lampshades can be made out of a large variety of materials like paper, glass, fabric, stone, or any material that let light in. Often conical or cylindrical in shape, lampshades can be found on floor, desk, tabletop, or suspended lamps. The term can also apply to the glass or other materials hung around many designs of ceiling lamp. Some lamp shades are also lined with a hard-backed opaque lining, often white or gold, to reflect as much light as possible through the top and bottom of the shade while blocking light from emitting through the walls of the shade itself. In other cases, the shade material is deliberately decorative so that upon illumination it may emphasize a display of color and light emitting through the shade surface itself.
