Abstract

L'invention propose un dispositif lumineux comportant une première source lumineuse (54) qui émet vers l'arrière selon un axe d'émission (AE1), un guide de lumière (102) pour guider des rayons lumineux pour former et émettre, selon un axe de sortie, un faisceau de rayons lumineux, guide de lumière (102) qui comporte une face d'entrée (104), une face de sortie du faisceau de sortie, au moins une première surface réfléchissante (106) et une deuxième surface réfléchissante (108) de manière à produire une double réflexion de façon que, les rayons lumineux soient parallèles entre eux et que l'axe de sortie forme un angle de plus de quatre-vingt-dix degrés d'angle par rapport à l'axe d'émission (AE1), caractérisé en ce que, en aval de la deuxième surface réfléchissante (106), le guide de lumière (102) comporte un tronçon de guidage (110). Un ensemble lumineux comporte plusieurs dispositifs lumineux, et la pluralité de guides de lumière (102) sont réalisés en une seule pièce (100).
