Abstract

Un dispositif d’éclairage (DE) comprend N guides de lumière (GL) comportant chacun une première partie (P1) recevant par une face d’extrémité (FE) des photons générés par une source (S) associée et une seconde partie (P2) comportant une face avant (FV) par laquelle sortent des photons issus de cette première partie (P1), avec N ≥ 1. La première partie (P1) de chaque guide de lumière (GL) présente au moins une courbure définissant un coude et contraignant les photons pénétrant par sa face d’extrémité (FE) à rejoindre la face avant (FV) de la seconde partie (P2) après au moins une réflexion interne dans cette première partie (P1).
