L'invention concerne un dispositif d'éclairage (1) pour émettre de la lumière à plusieurs longueurs d'onde, lequel comprend : une source de lumière (10) ; un dispositif de conversion de longueurs d'onde (2) disposé dans une zone d'émission de la source de lumière (10), laquelle comprend au moins une première zone de conversion (KB3a, KB3b, ..., KB3n) comprenant un premier matériau (3a) de conversion de longueurs d'onde et une deuxième zone de conversion (KB3a', KB3b', ..., KB3n') comprenant un deuxième matériau (3b) de conversion de longueurs d'onde. La première zone de conversion (KB3a, KB3b, ..., KB3n) est mise au point pour convertir de la lumière provenant de la source de lumière (10) en une première longueur d'onde, et la deuxième zone de conversion (KB3a', KB3b', ..., KB3n') est mise au point pour convertir de la lumière provenant de la source lumineuse (10) en une deuxième longueur d'onde. La première et la deuxième longueur d'onde sont différentes. Les zones de conversion (KB3a, KB3b', ..., KB3n) sont disposées côte à côte latéralement.
