Abstract

L'invention porte sur un réflecteur (30) pour dispositif d'éclairage et/ou de signalisation (10) d'un véhicule automobile (1), le réflecteur (30) comprenant des premières facettes (100) destinées à réfléchir un faisceau lumineux (F) issu d'une source lumineuse (11) suivant une direction principale d'éclairage (E), le profil projeté de chaque première facette (100) sur un plan de projection perpendiculaire à une telle direction principale d'éclairage (E) étant sensiblement rectangulaire et/ou présentant une largeur sensiblement constante, mesurée dans la direction sensiblement transversale (Y), le réflecteur (30) comprenant au moins une seconde facette (200) destinée à réfléchir également un tel faisceau lumineux (F) issu d'une source lumineuse (11), cette au moins une seconde facette (200) étant réorientée autour d'une telle direction principale d'éclairage (E), le profil projeté de cette au moins une seconde facette (200) sur ledit plan de projection ayant une largeur (L) variable, mesurée dans la direction sensiblement transversale (Y).The invention relates to a reflector (30) for a lighting and / or signaling device (10) of a motor vehicle (1), the reflector (30) comprising first facets (100) intended to reflect a light beam. (F) from a light source (11) along a main direction of illumination (E), the projected profile of each first facet (100) on a projection plane perpendicular to such a main direction of illumination (E) being substantially rectangular and / or having a substantially constant width, measured in the substantially transverse direction (Y), the reflector (30) comprising at least one second facet (200) intended to also reflect such a light beam (F) coming from a light source (11), this at least one second facet (200) being reoriented around such a main direction of illumination (E), the projected profile of this at least one second facet (200) on said projection plane having a variable width (L), me safe in the substantially transverse direction (Y).
