Description

Um die bei Gaserntladung&röhren auftretende notwendige Spannungsd@ifferene zwischen Zünd- und Brennspannung zu erzielen, werden die Transformatoren für diese Röhren als Streutransformatoren ausgebildet oder die GasentladDungsröhren direkt durch Vorschalten von Drosseln oder Widerständen an die speisende Spannungsquelle angeschlossen. Da die Zündspannung jedoch meistens beträchtlich über der Brennspannung liegt, der Transformator aber für die volle Leistung (Zündspannung X Betriebsstrom) ausgelegt werden muß, ergeben sich recht erhebliche Leistungsgrößen, die zu vermeiden das Ziel der vorliegenden Erfindung ist.To avoid the voltage differences that occur during gas discharge and tubes to achieve between ignition and burning voltage, the transformers for this Tubes designed as scatter transformers or the gas discharge tubes directly by connecting chokes or resistors to the supply voltage source connected. However, since the ignition voltage is usually considerably higher than the operating voltage but the transformer for full power (ignition voltage X operating current) must be designed, there are quite significant performance levels that must be avoided is the aim of the present invention.

Gemäß der vorliegenden Erfindung wird ein aus der Streuinduktivität des Transformators und aus einem parallel zu einer Wicklung angeordneten Kondensator bestehender Strom- bzw. Schw.ingungskreis gebildet. Dieser wird auf die Netzfrequenz derart abgestimmt, daß durch Resonanz die zur Zündjung der Gasentladungsröhre notwendige Spannungsspitze erzielt wird. Auf Grund der Erfindung braucht der Transformator nur für die Brennspannung der Leuchtstoffröhre ausgelegt zu werden.According to the present invention, leakage inductance becomes one of the transformer and a capacitor arranged parallel to a winding existing current or oscillation circuit formed. This is based on the network frequency tuned in such a way that the resonance necessary for the ignition of the gas discharge tube Voltage peak is achieved. Due to the invention, the transformer needs to be designed only for the operating voltage of the fluorescent tube.

Die Zeichnung zeigt.in schematischer Darstellung ein Ausführungsbeispiel der Erfindung. Wie ersichtlich, ist zu dem Transformator i vorzugsweise zu dessen Sekundürwicklung ein Kondensator 2 parallel geschaltet, dessen Kapazität so bemessen ist, daß sie mit der Streuinduktivität dies, Transformators hei der Netzfrequenz in Resonanz kommt. Die durch die Resonanz auftretende, erheblich über der Sekundärspannung liegende Spannungsspitze wird zur Zündung ausgenutzt. Während der Dauer des Entladungsvorgangs wird der Kondensator durch die Entladungsröhre 3 praktisch kurzgeschlossen und somit ein Ansteigen der Spannung über den. vorgeschriebenen Wert vermieden. Es hesteht auch die Möglichkeit, die notwendige Kapazität durch die Eigenkapazität dies Transformators zu bilden.The drawing shows a schematic representation of an embodiment the invention. As can be seen, to the transformer i is preferably to its Secondary winding a capacitor 2 connected in parallel, whose capacitance is so dimensioned is that it is related to the leakage inductance of this transformer called the mains frequency comes into resonance. The one caused by the resonance, considerably above the secondary voltage Lying voltage peak is used for ignition. During the discharge process the capacitor is practically short-circuited by the discharge tube 3 and thus an increase in voltage across the. prescribed value avoided. It stands also the possibility of the necessary capacity through the internal capacity of this transformer to build.
