Abstract (en)
A lamp shade (2;23;26;32) is configured as at least one helix (2;23;26;32) having a plurality of coils (7;24;27;33). Simply by pulling one end of the helix (7;24;27;33) the length can be selected as desired. If e.g. much dimming or spreading of light is intended a helix (2;23;26;32) having a large number of windings or coils (7;24;27;33) is chosen or the helix (2;23;26;32) is compressed to the preferred lenght which satisfies the consumers lighting demand. The light penetrating between the coils (7;24;27;33) provides a pleasant illumination of its surroundings or serves as background light for decorative purposes. The lamp shade can be implemented in both ceiling lamps, wall lamps, table lamps, and floor lamps.
