Abstract

L'invention concerne un module optique (400) pour dispositif d'éclairage et/ou de signalisation, comportant au moins une source lumineuse générant un faisceau lumineux, au moins un moyen de coupure du faisceau lumineux, le ou les moyen(s) de coupure étant agencé(s) pour générer au moins une coupure basse et une coupure latérale du faisceau lumineux issu de la source lumineuse et une première et une seconde surfaces optiquement actives placées successivement le long du chemin du faisceau lumineux après le moyen de coupure caractérisé en ce que la première surface optiquement active comporte au moins une première série de motifs qui s'étendent selon une première direction et la deuxième surface optiquement active comporte au moins une deuxième série de motifs qui s'étendent selon une deuxième direction, lesdites première et deuxième directions étant sensiblement perpendiculaires.The invention relates to an optical module (400) for a lighting and / or signaling device, comprising at least one light source generating a light beam, at least one means for breaking the light beam, the means (s) for cut-off being arranged to generate at least one low cut and one lateral cut-off of the light beam coming from the light source and a first and second optically active surface successively placed along the path of the light beam after the breaking means characterized by the first optically active surface comprises at least a first series of patterns which extend in a first direction and the second optically active surface comprises at least a second series of patterns which extend in a second direction, said first and second directions being substantially perpendicular.

Dispositif d'éclairage et/ou de signalisation de véhicule automobile comprenant au moins un tel module.
