Abstract

L'INVENTION CONCERNE UNE LAMPE A DECHARGE BASSE PRESSION A VAPEUR DE MERCURE. L'AMALGAME DISPOSE DANS LA LAMPE ET ADAPTE A Y DEVELOPPER LA PRESSION DE VAPEUR D'EQUILIBRE PREDETERMINEE DE MERCURE, EST UNE COMBINAISON OU UN ALLIAGE DE MERCURE ET DE MANGANESE. APPPLICATION DE TELLES LAMPES A DECHARGE BASSE PRESSION ET A VAPEUR DE MERCURE A L'ECLAIRAGE DES LOCAUX.THE INVENTION RELATES TO A LOW PRESSURE DISCHARGE LAMP WITH MERCURY VAPOR. AMALGAM PROVIDED IN THE LAMP AND SUITABLE TO DEVELOP THERE THE PREDETERMINED BALANCED VAPOR PRESSURE OF MERCURY, IS A COMBINATION OR ALLOY OF MERCURY AND MANGANESE. APPLICATION OF SUCH LOW PRESSURE DISCHARGE AND MERCURY VAPOR LAMPS TO THE LIGHTING OF PREMISES.
