Abstract

Système d'éclairage pour véhicule automobile comprenant au moins un module d'éclairage comportant : - des sources de lumière comportant chacune une face de forme générale rectangulaire d'émission de lumière, les faces d'émission de lumière étant centrées sur une même droite définissant une direction d'alignement des sources, et - un dispositif optique de projection. Le module d'éclairage comporte en outre des guides de lumière, chaque guide étant couplé avec une des sources. Les guides sont répartis sur des première et seconde pièces de guidage distinctes de formes complémentaires, emboîtées l'une dans l'autre. La première pièce de guidage est placée en regard des faces d'émission de lumière et la seconde pièce de guidage est rapportée sur une surface libre du dispositif optique de projection. Le système d'éclairage est agencé de manière à former une tache lumineuse par source de lumière, chaque tache lumineuse ayant une forme de bande lumineuse.A lighting system for a motor vehicle comprising at least one lighting module comprising: light sources each having a generally rectangular face of light emission, the light-emitting faces being centered on the same straight line defining a source alignment direction, and - an optical projection device. The lighting module further comprises light guides, each guide being coupled with one of the sources. The guides are distributed on first and second separate guide parts of complementary shapes, nested one inside the other. The first guide piece is placed facing the light-emitting faces and the second guide piece is attached to a free surface of the projection optical device. The lighting system is arranged to form a light spot by light source, each light spot having a light band shape.
