EMI1.1
Es sind Leuchtröhren mit farbloser und durchsichtiger Hülle bekannt, welche eine gleichzeitig aus Edelgas und Quecksilberdampf bestehende Füllung besitzen. Bei einer derartigen Röhre, nämlich bei der mit Neongas gefüllten und mit einem Quecksilberzusatz versehenen Blaulichtentladungsröhre, tritt jedoch der Übelstand auf, dass diese ihre intensiv blaue Farbe verliert und stellenweise die rote Neonfarbe hindurchtreten lässt, sobald durch das Sinken der Aussentemperatur der Dampfdruck des Quecksilbers zu gering wird.
Es wurde nun gefunden, dass dieser Missstand vermieden wird, wenn der Edelgasanteil der Füllung aus einer Mischung von etwa 60 bis 75% Neon und 40 bis 25% Argon sich zusammensetzt.
Bei Mengenverhältnissen innerhalb dieser Grenzen zeigen die Röhren ständig die blaue Farbe.

EMI1.1
There are known fluorescent tubes with a colorless and transparent shell, which have a filling consisting of noble gas and mercury vapor at the same time. With such a tube, namely the blue light discharge tube filled with neon gas and provided with a mercury additive, the disadvantage arises that it loses its intense blue color and in places allows the red neon color to penetrate as soon as the vapor pressure of the mercury increases due to the drop in outside temperature becomes low.
It has now been found that this deficiency is avoided if the noble gas portion of the filling is composed of a mixture of about 60 to 75% neon and 40 to 25% argon.
If the proportions are within these limits, the tubes always show the blue color.
