Abstract
a. Appareil d'éclairage en lumière inactinique pour laboratoires de traitement de surfaces photosensibles. b. Appareil caractérisé en ce que la fenêtre pratiquée dans la paroi supérieure du boîtier pour permettre à la lumière inactinique de s'échapper vers l'extérieur, est munie d'un registre permettant de regler la surface de la fenêtre laissée libre pour le passage de la lumière, l'appareil comportant en outre un commutateur à trois positions permettant soit de couper l'alimentation de la source lumineuse inactinique, soit de faire fonctionner cette source à deux niveaux d'intensité différents, des pattes amovibles étant prévues sur l'une des grandes parois verticales du boîtier pour permettre d'accrocher celui-ci contre un mur ou une cloison. c. L'invention s'applique notamment au traitement des pellicules et plaques photographiques.
