Abstract

Le luminaire, notamment à but médicolégal, selon l'invention se compose d'un boîtier (2) dans lequel est disposé un moyen lumineux et qui présente une ouverture de sortie (3) à travers laquelle peut être diffusée la lumière du moyen lumineux dans une position de travail de celui-ci. Le moyen lumineux est alimenté en énergie électrique par le biais d'une source de courant et commandé à l'aide d'un dispositif de commande. Le moyen lumineux se compose de plusieurs sources de lumière (6a à 6f) de différentes formes qui sont disposées de manière à pouvoir être déplacées, notamment tournées dans le boîtier en vue de diffuser de la lumière de différentes qualités, les sources de lumière pouvant être déplacées en alternance en position de travail. Un large spectre lumineux peut ainsi être couvert avec le même luminaire sans qu'il soit nécessaire de changer les sources de lumière.
