Description

Leuchtvorrichtung mit elektrischen Entladungsröhren für Reklame-, Signal- und ähnliche Zwecke: Die Erfindung betrifft eine Leuchtvorrichtung mit elektrischen Glimxnentladungsröhren für Reklame-, Signal- und ähnliche Zwecke, bei der die nach hinten fallenden Strahlen in. bekannter Weise durch Reflektoren nach vorn geworfen werden. Das Wesentliche der Erfindung ist darauf gerichtet, daß die Endstutzen, in denen Entladungsröhren in an sich bekannter Weise liegen, mit abschraubbaren Verschlußbüchsen aus Isoliermaterial ausgerüstet sind, und daß die Entladungsröhren mit ihren Kopfenden an die Stromzuführungskabel durch mit Steckkontakten versehene Zuleitungen angeschlossen sind.Lighting device with electric discharge tubes for advertising, Signal and similar purposes: The invention relates to a lighting device with electrical Glimxn discharge tubes for advertising, signaling and similar purposes, in which the after rays falling behind are thrown forward in a known manner by reflectors will. The essence of the invention is aimed at the fact that the end pieces, in which discharge tubes are located in a manner known per se, with unscrewable Sealing sleeves are made of insulating material, and that the discharge tubes with their head ends to the power supply cable provided with plug contacts Leads are connected.

Bei dieser Konstruktion können, die Leuchtröhren nach der Fortnahme der abschraubbaren Büchsen bequem einzeln in ihrer Längsrichtung herausgezogen und ausgewechselt werden.With this construction, the fluorescent tubes can after removal of the unscrewable bushings conveniently pulled out individually in their longitudinal direction and be replaced.

Auf der Zeichnung ist eine derartige Leuchtvorrichtung in beispielsweiser Ausführungsform dargestellt.Such a lighting device is shown in the drawing as an example Embodiment shown.

Abb. z zeigt die ganze Leuchtvorrichtung in Vorderansicht; Abb. a ist ein Schnitt nach der Linie A-B der Abb. z in größerem Maßstabe, und in Abb. 3 ist, ebenfalls in größerem Maßstabe, ein Schnitt nach der Linie C-D der Abb. z veranschaulicht.Fig. Z shows the entire lighting device in a front view; Fig. A is a section along the line A-B of Fig. z on a larger scale, and in Fig. 3 is, also on a larger scale, a section along the line C-D of FIG illustrated.

In den beiden Schienen a sind die Glimmentladeröhren b in nicht zu großen Abständen voneinander angebracht. Sie ruhen in Stutzen c mit abschraubbaren Büchsen d aus Isoliermaterial, sind also mit den Schienena nicht leitend, verbunden. Der Strom wird vielmehr von den beiden Kabeln e durch kurze, mit Steckkontakten f versehene Zuleitungen g an die Kopfenden der Röhren herangebracht. Um eine gleichmäßig helle Leuchtfläche zu erreichen, liegt jede Röhre im Brennpunkt eines Reflektors A, der die nach hinten gerichtete Leuchtkraft der Röhre nach vorn wirft. So ist es möglich, ohne Verwendung von lichtverzehrenden Mattglasscheiben vor der Leuchtvorrichtung aus Blech, Pappe o. dgl. hergestellte Silhouetten für Reklame-und ähnliche Zwecke anzubringen, die vollkommen gleichmäßig von hinten beleuchtet werden.In the two rails a, the glow discharge tubes b are not closed large distances from each other. They rest in connection c with unscrewable Bushes d made of insulating material, are therefore non-conductive connected to the rails. Rather, the current is drawn from the two cables e through short, plug-in contacts f provided supply lines g brought up to the head ends of the tubes. To an evenly To achieve a bright luminous surface, each tube is at the focal point of a reflector A, which throws the backward-directed luminosity of the tube forward. So is it is possible without the use of light-consuming frosted glass panes in front of the lighting device Silhouettes made of sheet metal, cardboard or the like for advertising and similar purposes that are perfectly evenly backlit.
