Abstract

Electric light fitting with anti-dazzle screen and method of producing such an anti-dazzle screen, which consists of an assemblage of transverse ribs (13) and longitudinal parts (attachment strips 9, bracing rib 17). According to the invention, the transverse ribs (13) and the attachment strips (9) are produced from a sheet metal blank (30) provided with recesses (20, 28, 29), the attachment strips beeing bent to form cover flanges (11) with locking tongues (12) and the transverse ribs being bent pairwise to a V-shape and a bracing rib (17) being embedded within recesses or cut-out portions (20) of the transverse ribs, projections (22) and tabs (24) reaching into the recesses (20) and into the interior of the bracing rib, which projections and tabs are bent to flush abutment against the inside of the bracing rib for holding safely together such an anti-dazzle screen, which is to be hooked on to a reflector (4) of the light fitting, the free longitudinal edges (5, 6) of which are claw-shaped. <IMAGE> <IMAGE>
