There is proposed a luminaire (10) with which the exit angle of the light beams is restricted for the purpose of anti-dazzling. Further, in accordance with the invention there is attained in a simple manner and in particular without the employment of a light guide element a uniform emission of light over the entire surface of an optical element (14; 14-1, 14-2) arranged before or in the emission opening (13) of the luminaire (10). The optical element (14; 14-1, 14-2) has a plate-like core (16) of transparent material, which is occupied on one side with microprisms (17) which, with the formation of furrows (18) - starting from their roots - taper.
L'invention concerne un dispositif d'éclairage (10) dont l'angle de sortie des rayons lumineux est limité aux fins de protection contre l'éblouissement. L'invention permet d'obtenir de façon simple, notamment sans utilisation d'élément guide de lumière, un rayonnement uniforme de la lumière sur toute la surface d'un élément optique (14; 14-1, 14-2) qui est placé dans ou devant l'ouverture de rayonnement (13) du dispositif d'éclairage (10). L'élément optique (14; 14-1, 14-2) présente une base (16) qui est réalisée sous forme de plaque dans matériau transparent et dont une face est pourvue de microprismes (17) qui sont effilées à partir de leur racine pour former des rainures (18).
