Es ist bekannt, Quecksilberdampflampen und ähnliche Apparate dadurch zu zünden, daß die beiden Elektroden α und b, wie die Zeichnung zeigt, im Ruhezustande durch einen Leiter c von hinreichend hohem Widerstände, z. B. durch einen Kohlenfaden, verbunden sind und daß diese leitende Verbindung bei der Zündung an der Kathode unterbrochen wird, indem beispielsweise ein aufIt is known to ignite mercury vapor lamps and similar apparatus in that the two electrodes α and b, as the drawing shows, in the rest state by a conductor c of sufficiently high resistances, for. B. are connected by a carbon thread and that this conductive connection is interrupted during ignition at the cathode, for example by a
ίο der Kathode schwimmender, oben becherförmig vertiefter und mit Quecksilber gefüllter Schwimmer d aus magnetischem Stoffe durch eine mit der Lampe in Reihe geschaltete Magnetspule e abwärts gezogen wird. Im Anfange geht der Strom nicht durch den Quecksilberdampf, sondern nur durch den Leiter c und ist infolge des hohen Widerstandes des letzteren nur sehr schwach. Es ist daher schwer, die Spule e so zu bemessen, daß einerseits ihre Zugkraft bei diesem schwachen Strome hinreicht, den Schwimmer anzuziehen, daß aber doch andererseits ihr Widerstand nicht zu groß wird, weil sonst in der Spule während der Benutzung der Lampe zu große Verluste eintreten würden. Um' dieser Schwierigkeit zu entgehen, wird nach der Erfindung die Zugkraft der Spule bei der Zündung erhöht. Dies kann am einfachsten in der Weise geschehen, daß parallel zur Lampe, aber ebenfalls in Reihe mit der Spule e ein Widerstand f geschaltet ist. Um den Strom, welcher diesen Widerstand durchfließt, wird derjenige in der Spule e beim Zünden vermehrt. Nach erfolgter Zündung wird der Widerstand wieder ausgeschaltet, z. B. selbsttätig durch einen elektromagnetischen Schalter g, welcher durch den Lampenstrom beeinflußt wird, sowie dieser ungefähr seinen normalen Wert erreicht.ίο the cathode is drawn downwards by a magnetic coil e connected in series with the lamp, a floating float d made of magnetic material, recessed at the top and filled with mercury. In the beginning the current does not go through the mercury vapor, but only through the conductor c and is very weak because of the high resistance of the latter. It is therefore difficult to dimension the coil e so that on the one hand its tensile force is sufficient to attract the swimmer with this weak current, but on the other hand its resistance does not become too great because otherwise the losses in the coil during use of the lamp are too great would occur. In order to avoid this difficulty, according to the invention, the tensile force of the coil is increased during ignition. The easiest way to do this is to connect a resistor f parallel to the lamp but also in series with the coil e . The current in coil e is increased by the current that flows through this resistor during ignition. After the ignition has taken place, the resistor is switched off again, e.g. B. automatically by an electromagnetic switch g, which is influenced by the lamp current, as well as this approximately reaches its normal value.
Der gleiche Zweck könnte auch durch andere Mittel erreicht werden. Statt die den Amperewindungen proportionale Zugkraft durch Erhöhung des Stromes zu verstärken, könnte man auch beim Zünden die Windungszahl der Spule vermehren, indem besondere Hilfswindungen beim Zünden hinzu- und nach erfolgter Zündung abgeschaltet werden. Der Strom für die .Hilfswindungen kann dem Netze entnommen werden, an welches die Lampe angeschlossen ist, oder einer besonderen Stromquelle.The same end could be achieved by other means. Instead of the Ampere turns to increase proportional pulling force by increasing the current, one could also increase the number of turns of the coil during ignition by adding special Auxiliary windings are added during ignition and switched off after ignition. The current for the auxiliary windings can be taken from the network to which the Lamp is connected, or a special power source.
