Optical element for deviating light rays and method for producing the same

Optical element (9) for deflecting the entering therein and again emerging from this light beams such that their angle of emergence is limited, which is occupied on one side with microprisms (2) with a plate-shaped core (1) of transparent material, the with the formation of furrows (7), from its root (5) starting, taper, where the total of the microprisms cover surfaces (4) the light input face and the other side of the core (1), the light exit surface (3) and wherein the grooves (7) are covered with a reflective layer at least one side (12), characterized by an on the element core (1) facing away from the reflective layer (12) arranged sheet (11) of transparent material.
