Perfeccionamientos en la fabricación de tubos luminiscentes de baja tensión especialmente de alumbrado que funciona a baja tensión con o sin pared de vidrio fluorescente o revestidos de materias fluorescentes caracterizado porque como gas de relleno se recorre a una mezcla de argón y xenón o de Krypton tal que para el régimen del tubo queda constante la caida de tensión incluso después de la volatilización del vapor de mercurio empleado.Improvements in the manufacture of low-voltage luminescent tubes, especially for lighting that works at low voltage with or without a fluorescent glass wall or covered with fluorescent materials, characterized in that a mixture of argon and xenon or Krypton is passed through as filling gas such that for the tube regime, the voltage drop remains constant even after the volatilization of the mercury vapor used.
