Abstract

Optical element (9) for deflecting light beams, which enter and re-emerge from the latter, in such a way that their angle of emergence is limited, for use as a luminaire-cover for example, having a plate-like core (1) of transparent material which on one side is occupied by microprisms (2) that taper forming furrows (7), with, for example, all of the top surfaces (4) of the microprisms forming the light-entry face and the other side of the core (1) forming the light-emergence face (3), and with the furrows (7) being covered by a layer (12) that is reflective at least on one side, with, furthermore, a foil (11) of transparent material being provided on the side of the reflective layer (12) that is remote from the element core (1), and also methods for producing the optical element (9) and the reflective element (10) that has the reflective layer (12).
