Description

Zur Einleitung einer als Lichtquelle dienenden Gasentladung ist eine Spannung erforderlich, die höher liegt als die Spannung, die zur Aufrechterhaltung der Gasentladung benötigt wird. Weiter weichen diese beiden Spannungen meist von der örtlich vorhandenen Netzspannung, die zum Betrieb herangezogen werden muß, ab. Es ist bisher üblich, die infolge dieser Spannungsunterschiede vorhandene überschüssige Energie über Wirk- und Blindwiderstände abzufangen, wobei diese Widerstände gleichzeitig zur Kompensation der fallenden Charakteristik der Gasentladung herangezogen werden. Dieser Energieanteil geht der Nutzung verloren. Erfindungsgemäß wird dieser Nachteil dadurch vermieden, daß mit der Gasentladungsstrecke ein Energiespeicher in Reihe geschaltet wird, der die überschüssige Energie aufnimmt und im Wechselspiel dann wiederum an eine Gasentladungsstrecke abgibt und beide Gasentladungsvorgänge als Lichtquellen genützt werden, wobei eine impulsförnüge Energiebegrenzung die Kompensation der fallenden Charakteristik der Gasentladungsstrecke an Stelle der durch Widerstände erzwungenen Kompensation ersetzt. Hierbei ergibt sich der weitere Vorteil, daß das Intervall zwischen Energieaufnahme und -abgabe zeitlich so gewählt werden kann, daß dieser je nach zu erzielendeni Effekt dem Auge wahrnehmbar' oder infolge höherer Frequenz nicht mehr wahrnehmbar ist.To initiate a gas discharge serving as a light source is a Tension higher than the tension required to maintain it the gas discharge is required. Furthermore, these two tensions usually diverge the locally available mains voltage that must be used for operation. It has hitherto been customary to remove the excess that is present as a result of these voltage differences Intercept energy via real and reactive resistances, with these resistances at the same time can be used to compensate for the falling characteristics of the gas discharge. This energy share is lost in use. According to the present invention, this disadvantage becomes avoided by having an energy store in series with the gas discharge path is switched, which absorbs the excess energy and then in interplay in turn delivers to a gas discharge path and both gas discharge processes as Light sources are used, with a pulse-free energy limitation providing compensation the falling characteristic of the gas discharge path instead of that caused by resistors Forced compensation replaced. This has the further advantage that the The time interval between energy consumption and output can be selected so that that this, depending on the effect to be achieved, is perceptible to the eye or as a result of a higher one Frequency is no longer perceptible.

An Hand eines Schaltbeispiels sei die Erfindung näher erläutert. Im Bild sei U eine Spannungsquelle, an der in Reihenschaltung die Gasentladungsstrecke G mit dem Energiespeicher E liegt, der beispielsweise `in' der einfachsten Anwendung ein Kondensator sei. Parallel zum Energiespeicher E liegt eine weitere Gasentladungsstrecke g. Zur Zeit To des Einschaltens liegt die volle Spannung U an der Gäsentladungsstrecke G und erzwingt durch diese den Stromfluß. Infolge des Stromflusses wechselt das Potential von der Gasentladungsstrecke G in der Zeit Ti nach dem Energiespeicher E, die Gäsentladungsstrecke G -setzt aus und trennt den Energiespeicher E von der Spannungsquelle U. Das auf dem Energiespeicher E verbliebene Potential setzt die Gasentladungsstrecke ga in Funktion und gibt dort Lichtenergie ab, so daß der Kondensator E für die Spannungsquelle U wieder den Widerstandswert o annimmt. Das Potential U liegt dann wieder an der Gasentladungsstrecke G, so daß das Spiel ein fortwährendes bleibt.The invention will be explained in more detail using a circuit example. in the Let U be a voltage source at which the gas discharge path is connected in series G lies with the energy store E, which is, for example, `in 'the simplest application be a capacitor. Another gas discharge path lies parallel to the energy store E. G. At the time To of switching on, the full voltage U is applied to the gas charge path G and forces the current to flow through it. This changes as a result of the current flow Potential of the gas discharge path G in the time Ti after the energy store E, the gas charge path G -sets and separates the energy storage E from the Voltage source U. The potential remaining on the energy store E sets the Gas discharge path ga in function and emits light energy there, so that the capacitor E again assumes the resistance value o for the voltage source U. The potential U is then again on the gas discharge path G, so that the game continues remain.

Es ist von Vorteil, durch Einfügen eines Energiewandlers, zum Beispiel eines elektromagnetischen, einen schwingungsfähigen Energiespeicher zu bilden, wenn eine ruhige Lichtquelle erzeugt werden soll.It is beneficial by inserting an energy converter, for example an electromagnetic to form an oscillatable energy store, if a calm light source is to be generated.
