摘要

The lamp screen (1) has a flexible clamp (2, 3) and a partial screen material which can be tensioned (4). The clamp is circular and tensions the screen material. The screen material is transferable into a second condition relaxed by a first strained condition. A ring forms the clamp both in a first as well as in the second condition. The clamp can be twisted to the clamp.
