Abstract

L'INVENTION CONCERNE UNE LAMPE A DECHARGE DANS LA VAPEUR DE SODIUM A HAUTE PRESSION QUI EST MUNIE D'UNE ENCEINTE A DECHARGE (1) CONTENANT DU XENON ET UNE SUBSTANCE ABSORBANTE. LE XENON EST ABSORBE PARTIELLEMENT PAR LA SUBSTANCE ABSORBANTE ET EN DEGAGE, LORS DE L'AUGMENTATION DE LA TEMPERATURE. AINSI, UNE PRESSION APPROPRIEE DU XENON EST ASSUREE, TANT POUR L'AMORCAGE DE LA LAMPE QUE POUR L'ETAT DU FONCTIONNEMENT. CONFORMEMENT A L'INVENTION, LA SUBSTANCE ABSORBANTE EST PRESENTE DANS UNE CAVITE MENAGEE DANS LA PAROI DE L'ENCEINTE A DECHARGE. AINSI, ON A OBTENU UN SUPPORT SIMPLE POUR LADITE SUBSTANCE ABSORBANTE. APPLICATION: LAMPE A DECHARGE.THE INVENTION RELATES TO A LAMP FOR DISCHARGE IN HIGH PRESSURE SODIUM VAPOR WHICH IS EQUIPPED WITH A DISCHARGE CONTAINER (1) CONTAINING XENON AND AN ABSORBENT SUBSTANCE. XENON IS PARTIALLY ABSORBED BY THE ABSORBENT AND RELEASED SUBSTANCE WHEN THE TEMPERATURE IS INCREASED. THUS AN APPROPRIATE XENON PRESSURE IS ENSURED, BOTH FOR LAMP PRIMING AND IN OPERATING CONDITION. IN ACCORDANCE WITH THE INVENTION, THE ABSORBENT SUBSTANCE IS PRESENT IN A CAVITY PROVIDED IN THE WALL OF THE DISCHARGE VESSEL. THUS, A SIMPLE SUPPORT FOR THE SAID ABSORBENT SUBSTANCE HAS BEEN OBTAINED. APPLICATION: DISCHARGE LAMP.
