 Spannungen umschalten lässt. In den Fig. 2 b, sowie 4 a und 4 b ist beispielsweise eine Schaltung vorgesehen, die sich für eine Spannung und eine doppelt so grosse Spannung etwa 110 und 220 Volt verwenden lässt. Die Schaltung selbst ist bis auf die Umschaltbarkeit in dem österreichischen Patent 94055 beschrieben. Es bedeuten dabei in Fig. 2 b, 18 die   Indu1. -tionsspulen, welche   die Doppelunter-

   B. alle vier Lampenröhre in Reihe zünden (220 Volt), so werden die Klemmen I und IV nach Fig. 4 a verbunden und einer der Unterbrecher etwa 19   a   bzw. die Klemmen III, IV kurz geschlossen. Sollen die Lampenreihen paarweise in Reihe geschaltet werden (110 Volt), so erfolgt die Verbindung der Klemmen I bis IV nach Fig. 4 b. 



     PATENT-ANSPRÜCHE   :
1. Einrichtung zur Beleuchtung für photographische und chemigraphische Zwecke nach Stammpatent   Nr.   72804 mit automatischer   Zündung, dadurch gekennzeichnet,   dass der Lampenschalter mit den Lampen nicht nur in der Höhenrichtung und im Winkel zum Abwärts- und Aufwärtsleuchten verstellbar. sondern auch um eine quer zur gemeinsamen Ebene der Lampenrohre liegende Achse kippbar ist. um auch eine Zündung von Hand zu ermöglichen.

 Can switch voltages. In FIGS. 2 b, as well as 4 a and 4 b, a circuit is provided, for example, which can be used for a voltage and a voltage that is twice as high, approximately 110 and 220 volts. The circuit itself is described in Austrian patent 94055 except for switchability. It means in Fig. 2 b, 18 the Indu1. -tion coils, which the double sub-

   B. ignite all four lamp tubes in series (220 volts), the terminals I and IV are connected according to Fig. 4 a and one of the breakers about 19 a or the terminals III, IV short-circuited. If the rows of lamps are to be connected in series in pairs (110 volts), terminals I to IV are connected according to FIG. 4 b.



     PATENT CLAIMS:
1. Device for lighting for photographic and chemigraphic purposes according to parent patent no. 72804 with automatic ignition, characterized in that the lamp switch with the lamps is adjustable not only in the height direction and at the angle for downward and upward lighting. but also about an axis lying transversely to the common plane of the lamp tubes. to enable manual ignition.

 

Claims (1)

2. Einrichtung nach Anspruch 1, dadurch gekennzeichnet, dass der im Gestell drehbar und kippbar gelagerte Lampenrahmen aus dem Gestellager, nach Lösung einer Verriegelung heraushebbar und unabhängig vom Gestell ohne Unterbrechung der Stromzuleitung aufstellbar ist. 2. Device according to claim 1, characterized in that the lamp frame rotatably and tiltably mounted in the frame can be lifted out of the frame bearing after a lock has been released and can be set up independently of the frame without interrupting the power supply. 3. Einrichtung nach Stammpatent Nr. 72804, dadurch gekennzeichnet, dass in Reihe geschaltete Lampen oder Lampengruppen und im Nebenschluss zu diesen geschaltete Unterbrecher durch Umstellung der Klemmenkontakte für einfache oder mehrfache Spannung umschaltbar sind. EMI2.2 3. Device according to parent patent no. 72804, characterized in that series-connected lamps or groups of lamps and shunted to these connected breakers can be switched by switching the terminal contacts for single or multiple voltage.
