Lampshade for use as hanging light in e.g. state library, has screen units with surfaces that are connected to profile by shaft, where distance between surfaces is not more than twenty five percent of diameter of one surface

摘要

The lampshade (LM) has screen units with large and small surfaces (SG, SK), which are connected centrally to a doubled-T-shaped, rotary symmetrical profile by a shaft. The shaft does not pass through the surfaces. Upper surfaces of the screen units are structured in the form of radially aligned partial circular arches. Distance between the surfaces (SG, SK) is not more than 25 percent of the diameter of the surface (SG).
