Abstract

LES LAMPES A DECHARGE DANS LA VAPEUR DE MERCURE A HAUTE PRESSION CONTENANT UN HALOGENURE METALLIQUE ATTEIGNENT ASSEZ SOUVENT PREMATUREMENT LA FIN DE LEUR DUREE DE VIE PAR FUITES DU PINCEMENT. CONFORMEMENT A L'INVENTION, CET INCONVENIENT EST EMPECHE PAR REVETEMENT DE LA FEUILLE METALLIQUE 14, INCORPOREE COMME ENTREE DE COURANT DANS LE PINCEMENT 12, D'UN METAL CHOISI DANS LE GROUPE COMPRENANT TA, NB, V, CR, ZR, TI, Y, LA, SC ET HF. DE PLUS, SI LA PARTIE 33 DE L'ENTREE DE COURANT EXTERIEURE 20 SITUEE DANS LE PINCEMENT 12 EST AU MOINS SUPERFICIELLEMENT CONSTITUEE PAR L'UN DESDITS METAUX, ON EMPECHE EN OUTRE L'ECHAPPEMENT DE METAUX ALCALINS DE L'AMPOULE 10.HIGH PRESSURE MERCURY VAPOR DISCHARGE LAMPS CONTAINING METAL HALOGENIDE FREQUENTLY REACH THE END OF THEIR LIFETIME BY PINCH LEAKS. IN ACCORDANCE WITH THE INVENTION, THIS DISADVANTAGE IS PREVENTED BY COATING THE METAL SHEET 14, INCORPORATED AS A CURRENT INPUT IN THE PINCH 12, OF A METAL CHOSEN FROM THE GROUP INCLUDING TA, NB, V, CR, ZR, TI, Y , LA, SC AND HF. IN ADDITION, IF THE PART 33 OF THE EXTERNAL CURRENT INPUT 20 LOCATED IN THE CLAMP 12 IS AT LEAST SUPERFICIALLY CONSTITUTED BY ONE OF THE SAID METALS, THE ESCAPE OF ALKALINE METALS FROM THE BULB 10 IS ALSO PREVENTED.
