Abstract (en)
[origin: WO0136867A1] The invention relates to an anti-dazzling transparent screen for longitudinal illuminants (2). The inventive screen covers the illuminant (2) over the length thereof for preventing dazzling of the illuminant (2). The surface of the transparent screen is formed by prisms (10) that are situated in parallel next to each other. The aim of the invention is to obtain room illumination which is even and not dazzling at all. The inventive anti-dazzling transparent screen has prisms (10) which are situated essentially along the illuminant (2) in such a way that the rays of light (13) are totally reflected on at least one of the prism surfaces (11, 12), whereby said rays impinge on said prism surface (11, 12).
