Description
Glimmlampen ohne entwickelte positive Entladungssäule, auch solche, die mit Edelgasgemischen arbeitend Phosphore zum Leuchten bringen, sind bekannt. Die Elektrodenbehandlung dieser Lampen, 5(My)A/cm(exp)2 bei 200 V ergab eine praktisch ungenügende Leuchtwirkung.Glow lamps without a developed positive discharge column, including those that work with mixtures of noble gases, are known to illuminate phosphors. The electrode treatment of these lamps, 5 (My) A / cm (exp) 2 at 200 V resulted in a practically inadequate luminous effect.
Der Erfindungsgegenstand betrifft eine derartige Fluoreszenzlampe, bei der die Edelgasfüllung, z.B. Nr, Ar, Kr, in einem Gasgemisch einen Partialdruck der Größenordnung von 3 mm Hg, praktisch bis zu 20 mm Hg aufweist. Als Begleitgase kommen Stickstoff oder Wasserstoff in Frage. Zur sich ständig wiederholenden Initialzündung wird vorzugsweise ein Oxydkathodenfleck auf einer der Elektroden angeordnet.The subject matter of the invention relates to such a fluorescent lamp in which the noble gas filling, e.g. Nr, Ar, Kr, in a gas mixture has a partial pressure of the order of 3 mm Hg, practically up to 20 mm Hg. Nitrogen or hydrogen can be used as accompanying gases. For the repetitive initial ignition, an oxide cathode patch is preferably arranged on one of the electrodes.
Die Elektroden werden vorzugsweise bifilar angeordnet, um magnetische Erscheinungen zu vermeiden. Gegebenenfalls werden feine Drahtwendel als Elektrodenmaterial gewählt. Der Abstand der Elektroden beträgt für 220 V etwa 2,5 bis 3,4 mm, die Belastung ca. 40 (My)A/cm(exp)2.The electrodes are preferably arranged in a bifilar manner in order to avoid magnetic phenomena. If necessary, fine wire coils are selected as the electrode material. The distance between the electrodes is around 2.5 to 3.4 mm for 220 V, the load is around 40 (My) A / cm (exp) 2.
