Abstract

Le luminaire (10) peut se monter au plafond et présente une connexion électrique par passage traversant formée dans une enceinte fixe (12) qui est montée ou suspendue au plafond par un tube de fixation (34). L'enceinte supérieure fixe (12) contient un bloc de jonction femelle de sécurité pour les doigts et un passage traversant pour permettre de tirer le fil électrique du bâtiment au travers de l'enceinte. Une enceinte pivotante (14) est reliée de manière pivotante à l'enceinte fixe (12) et contient un bloc de jonction mâle d'accouplement (42) qui est positionné dans l'enceinte. L'enceinte fixe et l'enceinte pivotante peuvent être verrouillées ensemble à l'aide d'un verrou (44) de telle sorte qu'en libérant le verrou l'enceinte pivotante intermédiaire peut pivoter en se dégageant de l'enceinte fixe pour déconnecter électriquement l'applique du circuit électrique. Dans ce nouveau luminaire les fusibles peuvent être montés comme on le désire adjacents à une ou à deux des connexions de jonction mâles.
