Abstract

Dispositif lumineux de signalisation de véhicule automobile comprenant aux moins deux guides de lumière flexibles et transparents superposés L’invention concerne un dispositif lumineux de signalisation (1.1) de véhicule automobile comprenant au moins deux guides de lumière (G1, G2, G3) flexibles et transparents, chaque guide de lumière comprenant : une nappe de guidage de lumière configurée pour guider la lumière par réflexion totale interne et pour émettre de la lumière vers l’extérieur de ladite nappe ;un groupe d’éléments d’injection de lumière configuré pour illuminer une région de ladite nappe de guidage de lumière ; et au moins deux sources de lumière (S1, S2, S3), chaque source de lumière étant couplée à un guide de lumière flexible et transparent. Selon l’invention, les deux guides de lumière sont superposées au moins partiellement l’un sur l’autre. Les sources de lumière présentent une propriété représentative d’une fonction de signalisation de véhicule automobile. Figure à publier avec l’abrégé : Figure 5a
