Abstract

Un mode de réalisation de l'invention consiste en un système d'éclairage qui contient une source de lumière non cohérente capable d'émettre de la lumière dans une première plage de longueur d'onde et un corps allongé qui émet de la lumière dans une deuxième plage de longueur d'onde lorsqu'il est éclairé par la lumière de la première plage de longueur d'onde. Le corps présente une dimension de longueur, une dimension de largeur et une dimension de hauteur. Au moins une partie du corps se rétrécit de telle sorte que sa largeur et/ou sa hauteur augmentent dans le sens de la longueur. Le corps comprend en outre une surface d'extraction. Une première surface de non-extraction s'étend sur au moins une partie de la longueur du corps et est disposée de manière à partager un bord commun avec la surface d'extraction. Au moins une partie de la lumière à la deuxième longueur d'onde subit une réflexion interne totale sur la surface de non-extraction. Au moins un réflecteur externe est disposé à proximité de la surface de non-extraction de manière à créer un interstice entre le réflecteur externe et la surface de non-extraction.
