Abstract

The invention relates to prism slats 10 for light guiding Venetian blinds for deflecting sun radiation with at least partly reflective slat upper sides. The slat upper sides are provided at least partly with a plurality of prismatic shaped grooves or holograms, to deflect sun radiation out. The invention is characterized in that a prismatic reflector system 10 comprising prism shaped grooves 51 is optically penetrated and spatially superimposed by at least one further secondary reflective system, so that sun radiation 11-16 inciding from outside on the prism slats 10 can partly be reflected back at the primary reflective system 31 or 32 into the outside space, and further portions of the light irradiation can, at the same time, be redirected by a secondary reflective system 32 into the interior space.
