Description
ELEKTRONISCHES VORSCHALTGEPÄT FUR LEUCHTSTOFF-LAhlPEN Die Erfindung betrifft ein starterloses,elektronisches Vorschaitgerät für Leuchtstoff-Lampen.Dises Gerät gestattet es,Leuchtstoff-Lampen an einer Gleichstromquelle von 4 bis ca 30 Volt zu betreiben.ELECTRONIC CONNECTOR FOR LUMINOUS LAHLPEN The invention relates to a starterless, electronic device for fluorescent lamps. Dises The device allows fluorescent lamps to be connected to a direct current source of 4 to approx. 30 Volt to operate.
Bisher als spezielle Wandler bekannte Vorsatzgeräte ahnlicher Art arbeiten meist als sogenannte Gegentaktwandler und sind aufgrund ihres aufwendigeren Aufbaus in den Gesamtabmessungen wesentlich grösser und in der Herstellung auch entsprechend teurer.Attachments of a similar type previously known as special converters mostly work as so-called push-pull converters and are more complex due to their Structure in the overall dimensions much larger and also in the production correspondingly more expensive.
Die vorliegende Erfindung behandelt ein Vorschaltgerat,welehes als Eintakt-Sperrwandler mit spezieller Spulen-und Kernanordnung einen sehr günstigen Wirkungsgrad aufweist und ausserdem einen sehr gedrängten Aufbau zulässt und billig herzustellen ist.Der vorgeschlagene längliche Aufbau der Sperrwandlerschaltung auf einer gedruckten Schaltungsplatte sowie die vorteilhafte Anordnung des Schalttransistors zwischen gedruckter Schaltung und ALU-Schiene bewirkt,dass die am Transistor entstehende Wärme sehr gut abgeleitet wird und ausserdem das Gerät durch den so ermöglichten gedrängten Aufbau sogar in kleine Handlampen eingebaut werden kann.Trotz der einfachen Konstruktion der Schwingspuledie gleichzeitig auch die Vorheizung der Lampenheizwendel dbernimmt,wird ein relativ hoher Wirkungsgrad erzielt,der bisher nur Gegentaktwandlern vorbehalten war. The present invention deals with a ballast, which as Single-ended flyback converter with a special coil and core arrangement is a very affordable one Has efficiency and also allows a very compact structure and cheap The proposed elongated structure of the flyback converter circuit a printed circuit board and the advantageous arrangement of the switching transistor between the printed circuit and the ALU rail causes the transistor generated Heat is dissipated very well and also the device through the so made possible The compact structure can even be built into small hand lamps. Despite the simple Construction of the voice coil, which also preheats the lamp heating coil takes over, a relatively high level of efficiency is achieved that was previously only possible with push-pull converters was reserved.

Die Schaltung nach Fig.i stellt einen normalen Sperrschwinger mit einem Transistor 2 dar'denn als Schutz gegen Falschpolung von der Batterie oder sonstigen Gleichspannungsquelle her eine Diode 1 vorgeschaltet ist.Der Sperrschwinger selbst kann für eine Schwingfrequenz von ca 1 - lo KIiz ausgelegt verden.Die beiden Wicklungen 3 u.4 sind Steuer-und Erregerwicklungen für Transistor und Schwing-und Transformatorspule 8.Die Diode 6 ist Schutzdiode für die Emmitter-Basisstrecke des Transistors,während der Widerstand 5 eine Strombegrenzung darstellt.Die Sekundrseite der Spule weist die beiden Wiclungen 9 und 12 fiir die Vorheizung der beiden Heizwendel auf.Ausserdem liefert die Wicklung 11 die notwendige Zünd-und Brennspannung für die Leuchtstoffröhre 14.Zur besseren Zündung wird die Wiclung 13 vorgesehen,deren einer Pol an der ALU-Schiene 16 liegt.Die ALU-Schiene dient gleichzeitig als halterung des Vorschaltgeräts und der Leuchtröhre,als Reflektor und als Zündhilfe. The circuit according to Fig.i provides a normal blocking oscillator a transistor 2 dar'denn as protection against reverse polarity from the battery or Another DC voltage source is connected upstream of a diode 1 itself can be designed for an oscillation frequency of approx. 1 - 10 KIiz. The two Windings 3 and 4 are control and excitation windings for transistor and oscillation and Transformer coil 8. Diode 6 is a protective diode for the emitter base line of the Transistor, while the resistor 5 represents a current limitation. The secondary side The coil has the two windings 9 and 12 for preheating the two heating coils In addition, the winding 11 supplies the necessary ignition and burning voltage for the fluorescent tube 14. For better ignition, the winding 13 is provided One pole is on the ALU rail 16. The ALU rail also serves as a bracket the ballast and the fluorescent tube, as a reflector and as an ignition aid.
