Abstract

L'invention concerne un dispositif d'éclairage et/ou de signalisation, notamment pour véhicule automobile, comprenant au moins une source de lumière (1) et un guide de lumière (2), ladite source (1) comprenant un support (4) et une pluralité de composants (6) émetteurs de lumière, disposés sur ledit support (4) de façon à émettre un faisceau lumineux, ledit dispositif étant configuré pour diriger ledit faisceau vers ledit guide (2), dans lequel ledit support (4) est un circuit imprimé et/ou lesdits composants (6) émetteurs de lumière sont des diodes électroluminescentes, dans lequel lesdits composants (6) émetteurs de lumière sont disposés de façon à définir une surface d'émission (10) dudit faisceau lumineux sur une face (12) dudit support (4), dans lequel ladite source de lumière (1) est configurée de façon à ce que ladite surface d'émission (10) présente un axe d'extension longitudinale, dans lequel ledit guide de lumière (2) comprend au moins une portion émettrice (20), configurée pour émettre de la lumière en dehors dudit guide (2), et au moins une portion de guidage (22), située entre ladite source (1) et ladite portion émettrice (20), configurée pour transmettre ledit faisceau lumineux de ladite source (1) à ladite portion émettrice (20).
Selon l'invention, ladite portion de guidage (22) présente une section plus faible que celle de ladite portion émettrice (20).
