Abstract
Abstract This invention discloses an assembled lampshade which includes a sector shade, a plurality of spiral connectors connected to the edges of the sector shade, and a plurality of supporting members connected to the sector shade and spiral connectors to construct a firmly assembled lampshade. During transport and storage of this lampshade, all of the supporting members can be disassembled and the sector shade with the spiral connectors secured thereto can be flattened as a result of their flexibility. Therefore, the space occupied by the lampshade is significantly reduced. When necessary, the lampshade can be readily re-assembled without any special skills.
