Abstract

L’invention concerne un module optique (1,20) d’un système lumineux (10, 100) d’un véhicule automobile, comprenant : au moins une source lumineuse (2, 22, 23) ; un système optique primaire (4, 40) comprenant au moins un organe optique primaire (5, 50), ledit organe optique primaire étant agencé pour former une image primaire à partir de ladite source lumineuse ; un masque (7, 70) disposé en aval du système optique primaire et présentant au moins deux zones (71, 72, 73, 74), l’une des zones (71, 74) étant opaque et l’autre (72, 73) étant apte à laisser de la lumière, lesdites zones étant agencées en vis-à-vis du système optique primaire pour former une image secondaire à partir de l’image primaire; un système optique de projection (9) agencé pour projeter au sol l’image secondaire formée par le masque. Figure à publier avec l’abrégé : Fig. 1The invention relates to an optical module (1,20) of a lighting system (10, 100) of a motor vehicle, comprising: at least one light source (2, 22, 23); a primary optical system (4, 40) comprising at least one primary optical member (5, 50), said primary optical member being arranged to form a primary image from said light source; a mask (7, 70) arranged downstream of the primary optical system and having at least two zones (71, 72, 73, 74), one of the zones (71, 74) being opaque and the other (72, 73 ) being capable of letting light, said zones being arranged opposite the primary optical system to form a secondary image from the primary image; an optical projection system (9) arranged to project the secondary image formed by the mask onto the ground. Figure to be published with the abstract: Fig. 1
