A reinforcement ring (11) is loosely fitted on the outside of a cover (10), and is provided with flaps (12) which pass radially through holes (13) in the cover, and on its inside support inner components (14) which are concentric with the ring. The components are located on the flaps, and together with the ring define a ring-shaped gap accommodating the edge part of the cover. The components comprise a second ring (14) and a plate. Both rings (11,14) have a circular cross-section, and at least one of them is sprung, acting as support units for one or more fixtures for assembling the lamp screen. The flaps (12) act as fixtures for components used for the suspension of the screen. |
