mit einer Neonfüllung versehen. Der durch die vordere Kammer hindurchzuschickende Strom muss, um im Zusammenhang mit den gewählten Füllungen und der Lichtstreuung des Gefässes eine rein weisse Lichtfarbe sicherzustellen, acht-bis zwolfmal so gross sein wie der durch die hintere Kammer hindurch- gesohickte Strom. Als besonders zweckmässig hat es sich in der Regel erwiesen, wenn durch die vordere Kammer ein zehnmal so grosser Strom als durch die hintere Kammer geschickt wird.
Bei einer derartigen, eine längsverlaufende Scheidewand besitzenden Leuchtröhre von 1 m Länge und 22 mm Durchmesser wird zweckmässig für die vordere Kammer eine Stromstärke von 200 Milliampere und für die hintere Kammer eine Stromstärke von 20 Milliampere gewählt. Es kann aber auch bei annähernd gleichem Stromstärkeverhältnis für die vordere Kammer eine höhere Stromstärke oder auch eine niedrigere Stromstärke bis herab auf etwa 50 Milliampere verwendet werden. Niedrigere Stromstärken für beiden Kammern kommen vornehmlich dann-in Betracht, wenn der Rohrdurchmesser weniger als 22 mm beträgt. t Das in den beiden Kammern derl-euchtröhre untergebrachte Edelgas kann einen üblichen Druck von-2-15 mm aufweisen.
Die zweikammerige Röhre oder die beiden verschiedenfarbigen, hintereinander liegenden Röhren können geradlinig gestaltet oder auch in beliebiger Form, insbesondere auch Schriftzeichenform, gebogen sein.

provided with a neon filling. In order to ensure a pure white light color in connection with the selected fillings and the light scattering of the vessel, the current to be sent through the front chamber must be eight to twelve times as large as the current passed through the rear chamber. As a rule, it has proven to be particularly expedient if a current ten times as large as that through the rear chamber is sent through the front chamber.
In such a fluorescent tube 1 m long and 22 mm in diameter, which has a longitudinal partition, a current of 200 milliamperes is expediently selected for the front chamber and a current of 20 milliamperes for the rear chamber. However, a higher current intensity or a lower current intensity down to about 50 milliamperes can also be used with approximately the same current intensity ratio for the front chamber. Lower currents for both chambers are primarily considered when the pipe diameter is less than 22 mm. The noble gas accommodated in the two chambers of the l-you tube can have a usual pressure of -2-15 mm.
The two-chamber tube or the two tubes of different colors lying one behind the other can be designed in a straight line or also bent in any shape, in particular also in the form of characters.
