Adjustment mechanism for a lamp with a pleated lampshade

摘要

The lamp has a pleated lamp screen (1) that is held by a holding unit e.g. wire ring (6), at a supporting structure e.g. lamp stand (9) and supporting unit (17), where the holding unit is connected with folds (3) of the lamp screen. An adjustment mechanism e.g. lever mechanism (13), is engaged to the folds of the lamp screen in such a manner that formed openings of the lamp screen are changeable in their size alternatively, where the adjustment mechanism is movable relative to the supporting structure and the lamp screen.
