Description
Die Erfindung betrifft einen elektrischen Batteriescheinwerfer mit einer einen Transistorzerhacker speisenden Niederspannungstrockenbatterie und einer von der Sekundärwicklung des Zerhackertransformators gespeisten Neonleuchtröhre.The invention relates to an electric battery headlight with a transistor chopper feeding Low voltage dry battery and one from the secondary winding of the chopper transformer powered neon tube.
Aufgabe der Erfindung ist es, die Sicherheitsmaßnahmen zu erhöhen, die geeignet sind, die verwendeten Transistor-Bauelemente gegen Betriebsstörungen verursachende Funktions- oder Anschlußfehler zu schützen.The object of the invention is to increase the security measures that are appropriate to the used Transistor components against functional or connection errors causing malfunctions protection.
Die beiden Hauptgefahren, die zu einer Beschädigung der Transistor-Bauelemente des Scheinwerfers führen können, sind einerseits Bruch der Neonleuchtröhre und andererseits falschpoliger Anschluß der den Scheinwerfer speisenden Batterien.The two main dangers that damage the transistor components of the headlight can lead to breakage of the neon tube on the one hand and incorrect polarity connection of the on the other hand batteries powering the headlights.
Es ist an sich bekannt, zum Schutz von Transistoren bei im Lastkreis auftretenden außergewöhnlichen Betriebszuständen, durch die am Transistor ein unerwünschter Spannungsanstieg auftritt, parallel zur Emitter-Kollektor-Strecke des Transistors einen spannungsabhängigen Widerstand zu schalten, welcher die eintretende Spannungserhöhung auffängt.It is known per se to protect transistors in the event of unusual occurrences in the load circuit Operating states through which an undesired voltage increase occurs on the transistor, parallel to Emitter-collector path of the transistor to switch a voltage-dependent resistor, which the absorbs any increase in voltage.
Nach der Erfindung ist bei einem Batteriescheinwerfer der eingangs genannten Art zum Schutz des Transistors zwischen den Enden der mit der Emitterelektrode bzw. der Kollektorelektrode des Transistors verbundenen Primärwicklungen ein spannungsabhängiger Schutzwiderstand angeordnet, der die durch Bruch der Neonleuchtröhre an den Wicklungsklemmen entstehende Spannungserhöhung auffängt. Da unter einem spannungsabhängigen Widerstand ein Widerstand verstanden wird, dessen Wert sich als umgekehrte Funktion der Spannung an seinen Klemmen ändert, entsteht so zwischen der Emitter- und der Kollektorelektrode eine Spannungsbegrenzung, die die Lebensdauer des Transistors in vorteilhafter Weise erhält.According to the invention is in a battery headlight of the type mentioned to protect the Transistor between the ends of the emitter electrode and the collector electrode of the transistor connected primary windings arranged a voltage-dependent protective resistor, which through Break of the neon tube at the winding terminals absorbs the increase in voltage. There a voltage-dependent resistor is understood to mean a resistance whose value is reverse function of the voltage at its terminals changes, so arises between the emitter and the collector electrode a voltage limit, which the life of the transistor in an advantageous manner receives.
Nach einem weiteren Merkmal der Erfindung ist bei einem Batteriescheinwerfer der eingangs genannten Art zum Schutz des Transistors parallel zu der von den Batterien gebildeten Energiequelle eine mit einer Sicherung in Reihe geschaltete Diode in der Weise angeordnet, daß bei falschpoligem Anschluß die Diode leitend und dadurch die Sicherung den Batterien direkt nebengeschaltet wird.According to a further feature of the invention, the one mentioned at the beginning is in the case of a battery headlight Kind to protect the transistor in parallel with the energy source formed by the batteries one with a Fuse series-connected diode arranged in such a way that if the polarity is incorrect, the The diode is conductive and thus the fuse is connected directly to the batteries.
Da auf diese Weise das Transistor-Bauelement der Vorrichtung sowohl auf der Speiseseite als auch auf der Abnahmeseite geschützt ist, wird die Lebensdauer dieses zerbrechlichen Bauteils beträchtlich erhöht.Because in this way the transistor component of the device both on the feed side and on the take-off side is protected, the service life of this fragile component is considerably increased.
In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes in einem Schaltbild dargestellt. In the drawing, an exemplary embodiment of the subject matter of the invention is shown in a circuit diagram.

Ein Transistor 1 ist über seine Emitter- bzw. Kollektorelektrode mit zwei Primärwicklungen 2 und 3 verbunden. Eine Sekundärwicklung 4 speist eine Neonleuchtröhre 5. Nach der ersten Sicherheitsvorrichtung ist zwischen der Emitter- und der Kollektorelektrode, die mit den Klemmen gleicher Polarität der Primärwicklungen 2 und 3 verbunden sind, ein spannungsabhängiger Schutzwiderstand 6 eingeschaltet, der bei Bruch der Neonleuchtröhre 5 die Überspannung an den Klemmen dieser Wicklungen aufnimmt.A transistor 1 has two primary windings 2 and 3 via its emitter or collector electrode tied together. A secondary winding 4 feeds a neon tube 5. After the first safety device is between the emitter and collector electrodes, which have the same polarity as the terminals Primary windings 2 and 3 are connected, a voltage-dependent protective resistor 6 switched on, the when the neon tube 5 breaks, the overvoltage at the terminals of these windings picks up.
Drei Batterien 7, 8 und 9 speisen den Scheinwerfer über in Reihe geschaltete Anschlußstellen la, 8a und 9 a. An den äußeren Klemmen entgegengesetzter Polarität der Batterien 7 und 9 ist eine mit einer leicht zugänglichen Sicherung 11 in Reihe geschaltete Germaniumdiode 10 parallel geschaltet, wobei die Diode im Falle eines falschpoligen Anschlusses der Batterien leitend und dadurch die Sicherung den Batterien direkt nebengeschaltet wird.Three batteries 7, 8 and 9 feed the headlight via series connecting points la, 8a and 9a. A germanium diode 10 connected in series with an easily accessible fuse 11 is connected in parallel to the outer terminals of opposite polarity of the batteries 7 and 9, the diode being conductive if the batteries are connected with the wrong polarity and thus the fuse is connected directly to the batteries.
