Abstract

Un dispositif d’éclairage comprend :- un bloc translucide (4) comprenant au moins une première surface d’entrée (16), une seconde surface d’entrée (18), une première surface de sortie (22) associée à la première surface d’entrée (16) et une seconde surface de sortie (24) associée à la seconde surface d’entrée (18) ;- une première source de lumière (6) disposée de manière à éclairer la première surface d’entrée (16) ;- une seconde source de lumière (8) disposée de manière à éclairer la seconde surface d’entrée (18). La première surface d’entrée (16) est configurée de sorte qu’un premier faisceau lumineux généré par la première source de lumière (6) et incident sur la première surface d’entrée (16) est transmis en direction de la première surface de sortie (22). La seconde surface d’entrée (18) est configurée de sorte qu’un second faisceau lumineux généré par la seconde source de lumière (8) et incident sur la seconde surface d’entrée (18) est transmis en direction de la seconde surface de sortie (24).
