Abstract

Lampe à un ou deux corps lumineux fixés dans une ampoule de verre sur deux ou quatre fils d'entrée de courant scellés dans un pied de verre formant un support. Un getter à action à court terme constitué de pentanitrure de phosphore est déposé sur le corps lumineux. Un getter à action à long terme constitué de poudre de zirconium est déposé aux extrémités des fils d'entrée de courant L'atmosphère que contient l'ampoule de verre consiste en un mélange de 90 % de xénon. et de 10 % d'azote, la pression de remplissage à froid étant de 1050 à 3275 millibars. Application essentiellement aux installations de signalisation ferroviaires ou routières.Lamp with one or two luminous bodies fixed in a glass bulb on two or four current input wires sealed in a glass base forming a support. A short-term getter consisting of phosphorus pentanitride is deposited on the luminous body. A long-term getter consisting of zirconium powder is deposited at the ends of the current input wires. The atmosphere in the glass bulb consists of a mixture of 90% xenon. and 10% nitrogen, the cold fill pressure being 1050 to 3275 millibars. Application essentially to railway or road signaling installations.
