Abstract

LA INVENCION SE REFIERE A UNA LAMPARA DE VAPOR DE MERCURIO DE BAJA PRESION QUE TIENE UNA EMISION MAXIMA EN TRES REGIONES ESPECTRALES, QUE TIENE UN RECIPIENTE DE DESCARGA TRANSMISOR DE RADIACIONES, ESTANCO AL GAS CON UN MERCURIO QUE CONTIENE UNA SUSTANCIA DE RELLENO DE GAS Y GAS NOBLE Y TIENE UNA CAPA LUMINISCENTE QUE CONTIENE UN PRIMER MATERIAL LUMINISCENTE CON UNA EMISION MAXIMA EN LA REGION DE 590-630 NM Y UN SEGUNDO MATERIAL LUMINISCENTE CON UNA EMISION MAXIMA EN LA REGION DE 520-565 NM. SEGUN LA INVENCION, LA SEGUNDA CAPA LUMINISCENTE QUEDA DEFINIDA POR LA FORMULA SR(2-X-Y)BAXSIO4:EU+2Y, EN QUE 0,2 1/2 X 1/2 1,4 Y 0,0005 1/2 Y 1/2 0,05. CON ESTO SE CONSIGUE QUE LA LAMPARA DE VAPOR DE MERCURIO DE BAJA PRESION TENGA UNA CAPA LUMINISCENTE CON CARACTERISTICAS FAVORABLES, AL TIEMPO QUE EL COSTE DE LA LAMPARA LUMINISCENTE ES BAJO.
