Abstract

1. Light-screen having - two outer walls (1) of which each has a screen edge (10) adjacent to a light exit port and an edge leg (11) bent back in a V-shape from the latter, - having transverse lamellas (2), each of which projects on each end face (200) by means of two hookshaped holding tabs (2.1, 2.2) with undercuts (20) through assigned mounting slots (1.1, 1.2) in the outer walls (1) - and is fixed in the desired position by a stop ridge (21) which is supported against a resilient counter-ridge (120) of the outer wall (1), characterized - in that the undercuts (20) of the holding tabs (2.1, 2.2) are directed against the screen edge (10), - in that at both ends closed holding slots (12) are provided in the edge legs (11) of each outer wall (1), in which the lower holding tab (2.2), adjacent to the screen edge (10), of each transverse lamella (2) engages, - in that the stop ridge (21) is arranged on the lower holding tab (2.2), and - in that the counter-ridge (120) is the limitation of the holding slot (12) facing away from the screen edge (10).
