ABSTRACT:
An anti-dazzling transparent screen for elongate illuminant bodies which covers the illuminant body over the length thereof for the purpose of anti-dazzling of a radiating sector of the illuminant body, has a surface formed by elongate prisms extending approximately parallel to one another and aligned substantially along the illuminant body. The prisms are positioned relative to the illuminant body such that on at least one of the prism surfaces a total reflection of the light beams, having entered the respective prism and impinging on this prism surface, occurs.
