Abstract

UNA LAMPARA DE DESCARGA DE VAPOR DE MERCURIO DE BAJA PRESION DE ACUERDO A LA INVENCION ESTA DOTADA CON UNA VASIJA (1) DE DESCARGA TUBULAR CON UN DIAMETRO INTERNO D. LA VASIJA (1) DE DESCARGA ENCIERRA UN ESPACIO (3) DE DESCARGA, QUE COMPRENDE MERCURIO Y UN GAS RARO, DE UNA MANERA IMPERMEABLE AL GAS. ELECTRODOS (5A, 5B) ESTAN DISPUESTOS EN PORCIONES (4A, 4B) EXTREMAS DE SU ESPACIO DE DESCARGA. LA VASIJA (1) DE DESCARGA ESTA DOTADA CON UNA CAPA (10) LUMINISCENTE QUE SOPORTA UNA CAPA (11) PROTECTORA QUE COMPRENDE UN OXIDO METALICO EN UNA SUPERFICIE (9) INTERIOR. EN LA LAMPARA DE ACUERDO A LA INVENCION, AL MENOS EL 75% DE PESO DEL OXIDO METALICO ESTA PRESENTE EN TOTAL EN LAS PORCIONES EXTREMAS (4A, 4B), EXTENDIENDOSE CADA UNA DE DICHAS PORCIONES (4A, 4B) EXTREMAS HASTA UNA DISTANCIA MAS ALLA DE LOS ELECTRODOS (5A, 5B) QUE ES TRES VECES EL DIAMETRO INTERNO DE LA VASIJA (1) DE DESCARGA. LA LAMPARA DE ACUERDO A LA INVENCION TIENE COMPARATIVAMENTE UN BAJO DECREMENTO LUMINOSO Y PUEDE SER FABRICADA COMPARATIVAMENTE EFICIENTEMENTE. LA LAMPARA DE ACUERDO A LA INVENCION PUEDE SER FABRICADA COMPARATIVAMENTE EFICIENTEMENTE POR UN METODO DE ACUERDO A LA INVENCION POR EL QUE UNA SUSPENSION QUE COMPRENDE UN OXIDO METALICO ES APLICADO SOBRE LA CAPA (10) LUMINISCENTE EN LA QUE LA SUSPENSION ES PULVERIZADA EN LA DIRECCION DE LA CAPA LUMINISCENTE DESDE UNA POSICION EXTERIOR A LA VASIJA DE DESCARGA EN CONSTRUCCION, OPUESTA A CADA PORCION EXTREMA.
