Description

Die Erfindung betrifft zunächst eine Schaltungsanordnung zum energiesparenden Betreiben einer Leuchtstoffröhre gemäß dem Oberbegriff des Anspruchs 1.The invention first relates to a circuit arrangement for energy-saving operation of a fluorescent tube according to the Preamble of claim 1.

Eine derartige Leuchtstoffröhre besteht in der Regel aus einem röhrenförmigen Entladungsgefäß aus Glas, an dessen Endkappen Glühkathoden eingeschmolzen sind. In der Regel ist das Entladungsgefäß evakuiert und mit Argon und Quecksilber gefüllt. Die Glühkathoden sind an beiden Endkappen jeweils als zwei Anschlüsse nach außen geführt. Über diese Anschlüsse ist eine derartige Leuchtstoffröhre nun in Fassungen elektrisch und mechanisch aufgenommen. Das Betreiben einer derartigen Leuchtstoffröhre erfolgt meist an einer Wechselstromquelle, wobei zum Zünden der Gasentladung eine Drossel und ein einfach als Starter bezeichneter Glimmzünder notwendig ist. Allerdings führen die Drossel und der Starter einen zusätzlichen Verbrauch an Energie bzw. eine Verminderung des Wirkungsgrades herbei. Weil eine derartige Leuchtstoffröhre andererseits eine vergleichsweise preisgünstige und zuverlässige Lichtquelle ist, wird ein Wirkungsgrad in der Größenordnung von nur 0,5 in Kauf genommen. Such a fluorescent tube usually consists of a tubular discharge vessel made of glass, on the End caps hot cathodes are melted. Usually is the discharge vessel is evacuated and filled with argon and mercury filled. The hot cathodes are on both end caps led to the outside as two connections. About these Such a fluorescent tube is now in connections Sockets recorded electrically and mechanically. The Such a fluorescent tube is usually operated an AC power source, for igniting the gas discharge a choke and one simply called a starter Glow starter is necessary. However, the throttle and lead the starter consumes additional energy or a reduction in efficiency. Because one such fluorescent tube, on the other hand, a comparative is an inexpensive and reliable light source Efficiency in the order of only 0.5 in purchase taken.

Es ist nun bekannt zum energiesparenden Betreiben einer Leuchstoffröhre ein elektronisches Vorschaltgerät - kurz als EVG bezeichnet - zu verwenden. Dazu wird das EVG zwischen die Wechselstromquelle und die Anschlüsse der Leuchtstoffröhre geschaltet, wobei die Drossel und der Starter ersetzt werden. Schaltungstechnisch betrachtet stellt das EVG somit einen Sechspol dar. Mittels des EVGs läßt sich ein Wirkungsgrad in der Größenordnung von nahezu 1 erreichen.It is now known to operate an energy-saving Fluorescent tube an electronic ballast - short as Designated EVG - to use. For this purpose, the TOE is between the AC power source and the connections of the Fluorescent tube switched, the choke and the Starter to be replaced. Considered in terms of circuitry the TOE thus represents a six-pole. By means of the TOE an efficiency of the order of magnitude of almost 1 to reach.

Von großem Nachteil ist nun, daß elektrische Geräte, wie zum Beispiel Lampen, in denen konventionell betriebene Leuchtstoffröhren verwendet werden, sich nur unter einem extrem hohen und sehr kostenintensiven Aufwand auf einen energiesparenden Betrieb mit EVG umrüsten lassen. Denn eine Umrüstung würde neben den Anschaffungskosten des EVG zeitund lohnintensive Installationskosten mit sich bringen, da neben der Drossel und dem Starter die gesamte Verkabelung auszutauschen wäre.A great disadvantage is that electrical devices such as Example lamps in which conventionally operated Fluorescent tubes are used only under one extremely high and very costly effort on one Have energy-saving operation retrofitted with an ECG. Because one In addition to the acquisition costs of the TOE, conversion would be time-consuming bring wage-intensive installation costs, because in addition to the choke and the starter, the entire wiring would be exchanged.

Deshalb liegt der Erfindung die Aufgabe zugrunde, eine Schaltunganordnung zu entwickeln, die sich auf einfache Weise für eine eingangs genannte Leuchtstoffröhre zum energiesparenden Betreiben nachrüsten läßt.Therefore, the invention has for its object a Develop circuit arrangement that is simple Way for a fluorescent tube mentioned at the beginning retrofit energy-saving operation.

Die Lösung dieser Aufgabe erfolgt gemäß dem kennzeichnenden Teil des Anspruchs 1. Demnach stellt die erfindungsgemäße Schaltungsanordnung einen Vierpol dar, der sich auf einfache Weise nach Auftrennen zweier Leitungen mit der bestehenden Verkabelung verschalten läßt. Beim Verschalten der erfindungsgemäßen Schaltungsanordnung ist lediglich darauf zu schauen, daß die Eingangsklemmen des Vierpols mit den zwei Anschlüssen an der einen Endkappe und mit der Drossel eine Reihenschaltung bilden, die zu der Wechselstromquelle parallel geschaltet ist, und daß die Ausgangsklemmen des Vierpols mit den zwei Anschlüssen an der anderen Endkappe elektrisch verbunden sind. Ansonsten erweist sich aufgrund des Wechselstrombetriebs ein Vertauschen einzelner Anschlüsse bzw. Klemmen als unkritisch. Ebenso kann die zu der Wechselstromquelle parallel geschaltete Reihenschaltung aus den Eingangsklemmen des Vierpols, den zwei Anschlüssen an der einen Endkappe und der Drossel eine beliebige Reihenfolge aufweisen. Insofern kann die Verschaltung der erfindungsgemäßen Schaltungsanordnung im Prinzip von jedermann vorgenommen werden. Auch bleibt beim Verschalten die ohnehin vorhandene Drossel erhalten, denn sie übernimmt für die erfindungsgemäße Schaltungsanordnung die Funktion eines Vorfilters, wodurch der Aufbau der erfindungsgemäßen Schaltungsanordnung nur eines geringen Bauraums bedarf und sich auch kostengünstig ausführen, läßt.This problem is solved according to the characteristic Part of claim 1. Accordingly, the invention Circuit arrangement represents a four-pole, which is based on simple Way after disconnecting two lines with the existing one Wiring can be connected. When interconnecting the circuit arrangement according to the invention is only thereon to see that the input terminals of the four-pole with the two connections on one end cap and with the throttle form a series connection to the AC power source is connected in parallel, and that the output terminals of the Quadruple with the two connections on the other end cap are electrically connected. Otherwise it turns out due of AC operation swapping individual Connections or terminals as uncritical. Likewise, the too the AC source connected in parallel from the input terminals of the four-pole, the two connections at one end cap and the throttle any Order. In this respect, the interconnection of the Circuit arrangement according to the invention in principle of everyone can be made. Also stay connected receive the throttle that is already there, because it takes over the function for the circuit arrangement according to the invention of a pre-filter, whereby the structure of the invention Circuit arrangement requires only a small space and can also be carried out inexpensively.

Je nachdem an welcher Stelle die Leitung, in der der Starter zwischengeschaltet ist, beim Verschalten aufgetrennt wird, liegt der Starter entweder an der Eingangs- oder der Ausgangsseite der erfindungsgemäßen Schaltungsanordnung an. Damit ein Stromfluß für die ordnungsgemäße Funktion der Schaltungsanordnung gewährleistet ist, wird der Starter überbrückt. Dazu wird er einfacherweise gegen eine kurzgeschlossene Ausführung in seiner bestehenden Fassung ausgetauscht. In dem Fall, daß der Starter auf der Eingangsseite der erfindungsgemäßen Schaltungsanordnung liegt, kann er vorteilhafterweise gegen eine elektrische Sicherung ausgetauscht werden, die sich in die bestehende Fassung einsetzen läßt, und die erfindungsgemäße Schaltungsanordnung gegen Überlastung zusätzlich schützt.Depending on where the line in which the starter is is interposed, is disconnected when interconnected, the starter is either at the input or the Output side of the circuit arrangement according to the invention. So that a current flow for the proper functioning of the Circuit arrangement is guaranteed, the starter bridged. To do this, he is simply against one short-circuit version in its existing version replaced. In the event that the starter on the Input side of the circuit arrangement according to the invention lies, it can advantageously against an electrical Fuse to be exchanged, which can be found in the existing Socket can be used, and the invention Circuit arrangement additionally protects against overload.

In besonders vorteilhafter Weise läßt sich die erfindungsgemäße Schaltungsanordnung nachrüsten, wenn sie in die Leuchtstoffröhre bzw. in eine der Endkappen der Leuchtstoffröhre integriert ist. Denn in diesem Fall ist nur die Leuchtstoffröhre auszutauschen, so daß jeglicher Eingriff in die bestehende Verkabelung entfällt. Eine weitere Alternative kann sein, daß die erfindungsgemäße Schaltungsanordnung in eine der die Leuchtstoffröhre aufnehmenden Fassungen integriert ist. Bei dieser Alternative ist/sind für ein Nachrüsten dann lediglich die Fassung(en) auszuwechseln.In a particularly advantageous manner, the Retrofit circuit arrangement according to the invention if they in the fluorescent tube or in one of the end caps of the Fluorescent tube is integrated. Because in this case is only replace the fluorescent tube so that everyone There is no intervention in the existing cabling. A another alternative may be that the invention Circuit arrangement in one of the fluorescent tubes receiving sockets is integrated. At this The alternative is / are only for retrofitting To replace the version (s).

Weiterhin betrifft die Erfindung eine Vorrichtung zum Verschalten einer erfindungsgemäßen Schaltungsanordnung mit einer eingangs genannten Leuchtstoffröhre. Diese erfindungsgemäße Vorrichtung zeichnet sich aus durch die Merkmale des kennzeichnenden Teils des Anspruchs 12.Furthermore, the invention relates to a device for Interconnect a circuit arrangement according to the invention with a fluorescent tube mentioned at the beginning. This Device according to the invention is characterized by the Features of the characterizing part of claim 12.

Mittels der erfindungsgemäßen Schaltungsanordnung ist es bereits möglich eine eingangs genannte Leuchtstoffröhre zum energiesparenden Betreiben auf einfache Weise nachzurüsten. Die erfindungsgemäße Vorrichtung zum Verschalten einer erfindungsgemäßen Schaltungsanordnung ermöglicht nun in besonders vorteilhafter Weise ein Nachrüsten, das weder ein Eingreifen in die bestehende Verkabelung der Leuchtstoffröhre, noch ein Austauschen der Leuchtstoffröhre oder deren aufnehmender Fassung(en) erfordert.It is by means of the circuit arrangement according to the invention already possible a fluorescent tube to begin with retrofit energy-saving operation in a simple manner. The device according to the invention for interconnecting a Circuit arrangement according to the invention now enables in a particularly advantageous way of retrofitting, which is neither a Intervene in the existing wiring of the Fluorescent tube, another replacement of the fluorescent tube or their receiving version (s) required.

Dafür weist die erfindungsgemäße Vorrichtung zum einen zwei Kontaktaufnahmen auf, die die zwei Anschlüsse einer der Endkappen der Leuchtstoffröhre elektrisch aufnehmen. Zum anderen weist die erfindungsgemäße Vorrichtung zwei Anschlüsse auf, die in einer der Fassungen elektrisch aufgenommen werden. Die Anschlüsse und die Kontaktaufnahmen der erfindungsgemäßen Vorrichtung sind gegeneinander elektrisch isoliert, wobei die Anschlüsse der erfindungsgemäßen Vorrichtung mit den Eingangsklemmen und die Kontaktaufnahmen der erfindungsgemäßen Vorrichtung mit den Ausgangsklemmen der erfindungsgemäßen Schaltungsanordnung elektrisch verbunden sind. Da die Kontaktaufnahmen und die Anschlüsse koaxial zueinander angeordnet sind, baut die erfindungsgemäße Vorrichtung so schmall, daß sie zwischen eine Endkappe der Leuchtstoffröhre und die zugehörige Fassung paßt.For this purpose, the device according to the invention has two Contacting the two ports one of the Electrically pick up the end caps of the fluorescent tube. To the others, the device according to the invention has two Connections on electrical in one of the sockets be included. The connections and the contacts the device according to the invention are against each other electrically insulated, the connections of the device according to the invention with the input terminals and the contacts of the device according to the invention the output terminals of the invention Circuit arrangement are electrically connected. Since the Contacts and the connections coaxial to each other are arranged, builds the device according to the invention narrow that they are between an end cap of the fluorescent tube and the corresponding version fits.

Der große Vorteil besteht folglich darin, daß sich ein Nachrüsten der erfindungsgemäßen Schaltungsanordnung mittels der erfindungsgemäßen Vorrichtung genauso einfach vornehmen läßt, wie das Auswechseln der Leuchtstoffröhre. Dazu wird die vorhandene Leuchtstoffröhre aus ihren Fassungen herausgenommen, dann wird die erfindungsgemäße Vorrichtung auf die Anschlüsse an einer Endkappe aufgesteckt, und anschließend wird die Leuchtstoffröhre zusammen mit der erfindungsgemäßen Vorrichtung wieder zwischen den Fassungen eingesetzt.The big advantage is therefore that one Retrofitting the circuit arrangement according to the invention by means of make the device according to the invention just as easily leaves, like changing the fluorescent tube. This will the existing fluorescent tube from its sockets removed, then the device according to the invention attached to the connections on an end cap, and then the fluorescent tube together with the device according to the invention again between the sockets used.

Die erfindungsgemäße Schaltungsanordnung selbst kann entsprechend den baulichen Gegebenheiten, die das elektrische Gerät, in dem sich die Leuchtstoffröhre befindet, bietet, von der erfindungsgemäßen Vorrichtung räumlich getrennt angeordnet werden, wobei die elektrische Verbindung zwischen der erfindungsgemäßen Vorrichtung und der erfindungsgemäßen Schaltungsanordnung über ein elektrisches Kabel in flexibler Weise erfolgen kann. Weil die erfindungsgemäße Schaltungsanordnung ein Vierpol ist, wird vorzugsweise ein vieradriges Kabel verwendet. Sowohl die erfindungsgemäße Vorrichtung, als auch die erfindungsgemäße Schaltungsanordnung können jeweils in Gehäusen angeordnet sein, die optional über elektrische Anschlußkontakte zum einfachen Verbinden mittels des Kabels verfügen.The circuit arrangement itself can according to the structural conditions that the electrical device in which the fluorescent tube located, offers, of the device according to the invention spatially separated, the electrical Connection between the device according to the invention and the circuit arrangement according to the invention electrical cable can be done in a flexible manner. Because the circuit arrangement according to the invention is a four-pole, a four-wire cable is preferably used. Either the device according to the invention, as well as the Circuit arrangement according to the invention can each in Housings can be arranged, optionally via electrical Connection contacts for easy connection using the cable feature.

In besonders bevorzugter Weise jedoch ist die erfindungsgemäße Schaltungsanordnung innerhalb des Gehäuses der erfindungsgemäßen Vorrichtung bzw. eines gemeinsamen Gehäuses angeordnet. Idealerweise weist dazu das Gehäuse der erfindungsgemäßen Vorrichtung einen sich parallel zur Längsachse der Leuchtstoffröhre erstreckenden Ansatz auf, in dem die erfindungsgemäße Schaltungsanordnung untergebracht ist. Dadurch lassen sich die erfindungsgemäße Schaltungsanordnung und Vorrichtung auf besonders einfache Weise und ohne die baulichen Gegebenheiten zu beeinträchtigen nachrüsten.However, in a particularly preferred manner Circuit arrangement according to the invention within the housing the device according to the invention or a common one Housing arranged. Ideally, the housing of the device according to the invention parallel to one another Longitudinal axis of the fluorescent tube extending approach, in which housed the circuit arrangement according to the invention is.

In Fig. 1 bis 3 ist eine handelsübliche Leuchtstoffröhre 1 in gerader Ausführung schematisch dargestellt. Die Leuchtstoffröhre 1 weist an beiden Endkappen 1a, 1b jeweils zwei Anschlußstifte 2a, 2b bzw. 3a, 3b auf. Über die Anschlußstifte 2a, 2b bzw. 3a, 3b wird die Leuchtstoffröhre 1 zwischen zwei sich gegenüberliegenden Fassungen 8, 9 aufgenommen. Dabei tragen die Fassungen 8, 9 die Leuchtstoffröhre 1 zum einen mechanisch, zum anderen umfassen die Fassungen 8,9 Kontaktaufnahmen 8a, 8b bzw. 9a, 9b, um eine elektrische Verbindung mit den Anschlußstiften 2a, 2b bzw. 3a, 3b der Leuchtstoffröhre 1 herzustellen. Bekanntermaßen kommen hierfür Drehfassungen in Betracht, zwischen denen die Leuchtstoffröhre senkrecht eingeführt wird, und durch Verdrehen um einen Winkel von 90 Grad elektrisch kontaktiert und mechanisch arretiert wird. Der Anschluß der Leuchtstoffröhre 1 an eine Wechselstromquelle 6 erfolgt nun in bekannter Weise unter Zwischenschalten eines eine Magnetspule 4a umfassenden Vorschaltgerätes, das einfach als Drossel 4 bezeichnet wird, sowie eines Starters 5. 1 to 3 is a commercially available fluorescent tube 1 shown schematically in a straight version. The Fluorescent tube 1 has at both end caps 1a, 1b two connecting pins 2a, 2b or 3a, 3b. About the The fluorescent tube becomes connecting pins 2a, 2b or 3a, 3b 1 between two opposite sockets 8, 9 added. The frames 8, 9 carry the Fluorescent tube 1 on the one hand mechanically, on the other comprise the versions 8, 9 contacts 8a, 8b and 9a, 9b to make an electrical connection to the connector pins 2a, 2b and 3a, 3b of the fluorescent tube 1. As is known, rotating versions come into consideration for this, between which the fluorescent tube is inserted vertically and by rotating it through an angle of 90 degrees electrically contacted and mechanically locked. The Connection of the fluorescent tube 1 to an AC power source 6 now takes place in a known manner with the interposition of a a ballast 4a comprising magnetic coil is simply referred to as throttle 4, and a starter 5th

Dazu ist gemäß Fig. 1 eine Kontaktaufnahme 8a einer Fassung 8 über eine erste Leitung 11 direkt mit einem Pol 6a der Wechselstromquelle 6 verbunden. Eine Kontaktaufnahme 9a der anderen Fassung 9 ist über eine zweite Leitung'12 mit dem anderen Pol 6b der Wechselstromquelle 6 verbunden, wobei in der zweiten Leitung 12 die Drossel 4 zwischengeschaltet ist. Weiterhin ist eine Kontaktaufnahme 8b der einen Fassung 8 mit einer Kontaktaufnahme 9b der anderen Fassung 9 über eine dritte Leitung 13 verbunden, in der der Starter 5 zwischengeschaltet ist.1 is a contact 8a of a socket 8 via a first line 11 directly to a pole 6a AC power source 6 connected. Contact 9a of the other version 9 is connected to the other pole 6b of the AC power source 6, wherein in the second line 12, the throttle 4 is interposed. Furthermore, there is contact 8b of one version 8 with a contact 9b of the other version 9 via a third line 13 connected in which the starter 5 is interposed.

Aufgrund des Wechselstrombetriebes spielt es keine Rolle, ob die Anschlußstifte 2a, 2b bzw. 3a, 3b der Leuchtstoffröhre 1, die Kontaktaufnahmen 8a, 8b bzw. 9a, 9b der Fassungen 8, 9 oder die Pole 6a, 6b der Wechselstromquelle 6 beim Verschalten untereinander vertauscht werden. Auch kann deshalb, wie in Fig. 2 gezeigt, die Drossel 4 in der ersten Leitung 11 anstatt, wie in Fig. 1 gezeigt, in der zweiten Leitung 12 zwischengeschaltet sein.Because of the AC operation, it does not matter whether the connecting pins 2a, 2b and 3a, 3b of the fluorescent tube 1, the contacts 8a, 8b and 9a, 9b of the sockets 8, 9 or the poles 6a, 6b of the alternating current source 6 at Interconnection can be interchanged. Can too therefore, as shown in Fig. 2, the throttle 4 in the first Line 11 instead of, as shown in Fig. 1, in the second Line 12 may be interposed.

Die erfindungsgemäße Schaltungsanordnung ist als ein Vierpol 7 ausgeführt, der gemäß Fig. 1 und 2 in der zweiten und dritten Leitung 12, 13 zwischengeschaltet ist. Dadurch bilden die Eingangsklemmen 7a, 7b des Vierpols 7 mit den Kontaktaufnahmen 8a, 8b der einen Fassung 8 bzw. der einen Glühkathode 1c der Leuchtstoffröhre 1, mit der Drossel 4 und mit dem Starter 5 eine Reihenschaltung, die zu der Wechselstromquelle 6 parallel geschaltet ist. Die Ausgangsklemmen 7c, 7d des Vierpols 7 sind mit den Kontaktaufnahmen 9a, 9b der anderen Fassung 9 bzw. der anderen Glühkathode 1d der Leuchtstoffröhre 1 elektrisch verbunden.The circuit arrangement according to the invention is a four-pole 7 executed, according to FIGS. 1 and 2 in the second and third line 12, 13 is interposed. Thereby form the input terminals 7a, 7b of the four-pole 7 with the Contacts 8a, 8b one version 8 and one Glow cathode 1c of the fluorescent tube 1, with the inductor 4 and with the starter 5 a series connection that leads to the AC source 6 is connected in parallel. The Output terminals 7c, 7d of the four-pole 7 are with the Contact 9a, 9b of the other version 9 and other hot cathode 1d of the fluorescent tube 1 electrically connected.

Wegen des Wechselstrombetriebes gilt gleichermaßen beim Verschalten des Vierpols 7, daß sowohl die Pole 7a, 7b der Eingangsklemmen, als auch die Pole 7c, 7d der Ausgangsklemmen untereinander vertauschbar sind. Ebenso kann die zur Wechselstromquelle 6 parallelgeschaltete Reihenschaltung aus Eingangsklemmen 7a, 7b, Glühkathode 1c, Drossel 4 und Starter 5 eine beliebige Reihenfolge aufweisen, beispielsweise so wie in Fig. 2 gezeigt.Because of the AC operation applies equally to Interconnecting the four-pole 7 that both the poles 7a, 7b of the Input terminals, as well as the poles 7c, 7d Output terminals are interchangeable. Likewise can those connected in parallel to the AC power source 6 Series connection of input terminals 7a, 7b, hot cathode 1c, Choke 4 and starter 5 in any order have, for example, as shown in Fig. 2.

Weiterhin kann der Vierpol 7 in der ersten und dritten Leitung 11, 13 zwischengeschaltet sein, so wie in Fig. 3 gezeigt ist. In diesem Fall bilden die Eingangsklemmen 7a, 7b des Vierpols 7 mit den Kontaktaufnahmen 9a, 9b der Fassung 9 bzw. der Glühkathode 1d der Leuchtstoffröhre 1, der Drossel 4 und dem Starter 5 eine Reihenschaltung, die zu der Wechselstromquelle 6 parallel geschaltet ist, und die Ausgangsklemmen 7c, 7d des Vierpols 7 sind mit den Kontaktaufnahmen 8a, 8b der Fassung 8 bzw. der Glühkathode 1c der Leuchtstoffröhre 1 elektrisch verbunden.Furthermore, the four-pin 7 in the first and third Line 11, 13 may be interposed, as in Fig. 3rd is shown. In this case, the input terminals 7a, 7b of the four-pole 7 with the contacts 9a, 9b of the Version 9 or the hot cathode 1d of the fluorescent tube 1, the throttle 4 and the starter 5 are connected in series, too the AC power source 6 is connected in parallel, and the Output terminals 7c, 7d of the four-pole 7 are with the Contact 8a, 8b of the socket 8 or the hot cathode 1c of the fluorescent tube 1 electrically connected.

Der Starter 5 ist gemäß Fig. 1 und 3, da dort in Reihe zu den Eingangsklemmen 7a, 7b geschaltet, als elektrische Sicherung 5a ausgeführt, und dient somit zum zusätzlichen Schutz der erfindungsgemäßen Schaltungsanordnung. Sofern dieser zusätzliche Schutz nicht gewünscht bzw. erforderlich ist, muß der Starter 5 überbrückt bzw. kurzgeschlossen werden. Falls der Starter 5 mittels einer Leitung 5b überbrückt ist, kann er auch wie in Fig. 2 gezeigt verschaltet werden, so daß die Ausgangsklemmen 7c, 7d des Vierpols 7 und der Starter 5 eine Reihenschaltung bilden, die mit der Glühkathode 1d der Leuchststoffröhre 1 elektrisch verbunden ist.The starter 5 is shown in FIGS. 1 and 3, since there in series the input terminals 7a, 7b switched as electrical Fuse 5a executed, and thus serves for additional Protection of the circuit arrangement according to the invention. Provided this additional protection is not desired or required is, the starter 5 must be bridged or short-circuited become. If the starter 5 by means of a line 5b is bridged, it can also as shown in Fig. 2 are connected so that the output terminals 7c, 7d of the Quadrupole 7 and starter 5 form a series connection, with the hot cathode 1d of the fluorescent tube 1 is electrically connected.

Der Vierpol 7 ist bei den Schaltungsbeispielen gemäß Fig. 1 bis 3 intern jeweils identisch aufgebaut. Eingangsseitig wird der Vierpol 7 von der Wechselstromquelle 6 versorgt, um ausgangsseitig eine Glühkathode 1d bzw. 1c der Leuchstoffröhre mit einem hochfrequenten Strom IHF zu beaufschlagen. Dabei ergibt sich im einzelnen folgende Funktionsweise:

  • a.) Eine Glühkathode 1c bzw. 1d der Leuchtstoffröhre 1 ist zu den Eingangsklemmen 7a, 7b des Vierpols 7 stets in Reihe geschaltet, so daß diese Glühkathode stets vom Eingangsstrom des Vierpols 7 durchflossen und somit vorgeheizt wird.
  • b.) Die zu den Eingangsklemmen 7a, 7b des Vierpols in Reihe geschaltete Glühkathode 1c bzw. 1d leitet desweiteren den die andere Glühkathode 1d bzw. 1c durchfließenden hochfrequenten Strom IHF auf die Eingangsseite des Vierpols 7 zurück, und dient somit als "virtuelle Masse". Für den hochfrequenten Strom IHF macht es im Prinzip keinen Unterschied, ob er direkt zur Masse oder über die Eingangsseite des Vierpols 7 zur Masse fließt. Dadurch, daß der hochfrequente Strom IHF hier über die Eingangsseite des Vierpols 7 zur Masse fließt, besteht vorteilhafterweise ein "kurzer" Weg, so daß die hochfrequente Abstrahlung auf niedrigstmöglichem Niveau liegt.
  • c.) Da die Drossel 4 zu den Eingangsklemmen 7a, 7b des Vierpols 7 ebenso stets in Reihe geschaltet ist, wirkt die Magnetspule 4a der Drossel 4 als ein Vorfilter, das zum einen den Leistungs- sowie Crestfaktor optimiert, und zum anderen elektromagnetische sowie hochfrequente Interferenzen unterdrückt.
  • d.) Der Eingangstrom des Vierpols 7 beträgt nur etwa 30 Prozent des Stromwertes, den eine konventionell - also ohne die erfindungsgemäße Schaltungsanordnung - betriebene Leuchtstoffröhre aufnimmt. Dadurch entsteht in der Drossel 4 nahezu keine Verlustleistung, wodurch die Drossel 4 im Betrieb außerdem kühl bleibt.
  • e.) Zu den Eingangsklemmen 7a, 7b des Vierpols 7 ist ein Kondensator 83 parallel geschaltet. Der Kondensator 83 dient in Verbindung mit der vorgeschalteten Drossel 4 zur Kompensation und bewirkt eine Erhöhung des Leistungsfaktors.
  • f.) Den Eingangsklemmen 7a, 7b des Vierpols 7 ist ein Gleichrichter 70 nachgeschaltet, der üblicherweise durch vier Dioden in Brückenschaltung gebildet wird. Da der hochfrequente Strom IHF wie unter b.) erläutert dem Eingangsstrom überlagert ist, werden für die Beschaltung des Gleichrichter 70 vorzugsweise sogenannte "Fast-Recovery"-Dioden verwendet.
  • g.) Zwischen den Eingangsklemmen 7a, 7b des Vierpols 7 und dem Plus- und Minusausgang des Gleichrichters 70 ist vorzugsweise jeweils ein Kondensator 81, 82 geschaltet, oder - anders ausgedrückt - der Gleichrichter 70 wird durch die Kondensatoren 81, 82 quasi überbrückt. Dies ist auf jeden Fall dann erforderlich, wenn für die Beschaltung des Gleichrichters 70 anstelle unter f.) genannter "Fast-Recovery"-Dioden einfache und somit kostengünstigere Dioden verwendet werden. Denn die Kondensatoren 81, 82 bilden eine hochfrequente Kurzschlußstrecke, über die der dem Eingangsstrom überlagerte hochfrequente Strom IHF wie unter b.) erläutert abfließen kann.
  • h.) Zu dem Plus- und Minusausgang des Gleichrichters 70 sind zwei in Reihe geschaltete Glättungskondensatoren 71, 72 parallel geschaltet. Dabei ist der Verbindungspunkt der Glättungskondensatoren 71, 72 mittels einer Leitung 73 auf eine der Eingangsklemmen 7a, 7b des Vierpols 7 brückbar, um die Gesamtkapazität der Glättungskondensatoren 71, 72 an unterschiedliche Spannungen der Wechselstromquelle 6, zum Beispiel 110 oder 220 Volt, anpassen zu können.
  • i.) Zwischen dem Plusausgang des Gleichrichters 70 und einer der Ausgangsklemmen 7c, 7d des Vierpols 7 ist ein Kopplungskondensator 77 geschaltet, so daß während der Startphase der Leuchtstoffröhre 1 die von dem hochfrequenten Strom IHF beaufschlagte Glühkathode 1d bzw. 1c vorgeheizt wird.
  • k.) Zwei von einem Steuerkreis 74 angesteuerte Transistoren 75, 76 sowie eine Magnetspule 79 bilden eine Hochfrequenzstufe zum Erzeugen des hochfrequenten Stromes IHF. Die Hochfrequenzstufe ist zwischen dem Plus- und Minusausgang des Gleichrichters 70 und den Ausgangsklemmen 7c, 7d des Vierpols 7 geschaltet. Der Steuerkreis 74 kann zum Beispiel ein Ringkernübertrager sein. Um allerdings die Verlustleistung und die damit verbundene Wärmeabgabe zu reduzieren, ist es von Vorteil für den Steuerkreis 74 ein handelsübliches Treiber-IC zu verwenden und Transistoren 75, 76 vom Typ MOS-FET zu verwenden.
  • l.) Zu dem Ausgang der Hochfrequenzstufe bzw. der Magnetspule 79 ist ein Blockungskondensator 78 in Reihe geschaltet. Der Blockungskondensator 78 verhindert, 'daß der niederfrequente Strom von der Wechselspannungsquelle 6 die Leuchstoffröhre 1 durchfließen kann, wodurch die Hochfrequenzstufe der hohen Spannung der Wechselstromquelle 6 ausgesetzt und somit beschädigt werden würde.
    • The four-pin 7 is internally identical in the circuit examples according to FIGS. 1 to 3. The four-pole 7 is supplied on the input side by the alternating current source 6 in order to apply a high-frequency current I HF to a hot cathode 1d or 1c of the fluorescent tube on the output side. The individual functions are as follows:
  • a.) A hot cathode 1c or 1d of the fluorescent tube 1 is always connected in series to the input terminals 7a, 7b of the four-pole 7, so that this hot cathode is always flowed through by the input current of the four-pole 7 and is thus preheated.
  • b.) The hot cathode 1c or 1d connected in series to the input terminals 7a, 7b of the four-pole also leads the high-frequency current I HF flowing through the other hot cathode 1d or 1c back to the input side of the four-pin 7, and thus serves as a "virtual ground ". In principle, it makes no difference for the high-frequency current IHF whether it flows directly to ground or via the input side of four-pole 7 to ground. Because the high-frequency current IHF flows here to ground via the input side of the four-pole 7, there is advantageously a "short" path, so that the high-frequency radiation is at the lowest possible level.
  • c.) Since the inductor 4 is also always connected in series to the input terminals 7a, 7b of the four-pole 7, the magnet coil 4a of the inductor 4 acts as a prefilter, which optimizes the power and crest factor on the one hand, and electromagnetic and high-frequency on the other Interference suppressed.
  • d.) The input current of the four-pole 7 is only about 30 percent of the current value which a fluorescent tube which is operated conventionally - that is to say without the circuit arrangement according to the invention - receives. As a result, there is almost no power loss in the throttle 4, which means that the throttle 4 also remains cool during operation.
  • e.) A capacitor 83 is connected in parallel to the input terminals 7a, 7b of the four-pole 7. The capacitor 83 is used in conjunction with the upstream choke 4 for compensation and causes an increase in the power factor.
  • f.) The input terminals 7a, 7b of the four-pole 7 is followed by a rectifier 70, which is usually formed by four diodes connected in a bridge. Since the high-frequency current I HF, as explained under b.), Is superimposed on the input current, so-called "fast recovery" diodes are preferably used for connecting the rectifier 70.
  • g.) A capacitor 81, 82 is preferably connected in each case between the input terminals 7a, 7b of the four-pole 7 and the plus and minus output of the rectifier 70, or - in other words - the rectifier 70 is quasi bridged by the capacitors 81, 82. This is necessary in any case if simple and thus less expensive diodes are used to connect the rectifier 70 instead of the “fast recovery” diodes mentioned under f.). This is because the capacitors 81, 82 form a high-frequency short-circuit path, via which the high-frequency current I HF superimposed on the input current can flow off, as explained under b.).
  • h.) To the plus and minus output of the rectifier 70, two smoothing capacitors 71, 72 connected in series are connected in parallel. The connection point of the smoothing capacitors 71, 72 can be bridged by means of a line 73 to one of the input terminals 7a, 7b of the four-pole 7 in order to be able to adapt the total capacitance of the smoothing capacitors 71, 72 to different voltages of the AC source 6, for example 110 or 220 volts ,
  • i.) A coupling capacitor 77 is connected between the positive output of the rectifier 70 and one of the output terminals 7c, 7d of the four-pole 7, so that during the starting phase of the fluorescent tube 1, the hot cathode 1d or 1c, which is acted upon by the high-frequency current IHF, is preheated.
  • k.) Two transistors 75, 76 controlled by a control circuit 74 and a magnet coil 79 form a high-frequency stage for generating the high-frequency current IHF. The high-frequency stage is connected between the plus and minus output of the rectifier 70 and the output terminals 7c, 7d of the four-pole 7. The control circuit 74 can be a toroidal core transformer, for example. However, in order to reduce the power loss and the associated heat dissipation, it is advantageous for the control circuit 74 to use a commercially available driver IC and to use transistors 75, 76 of the MOS-FET type.
  • l.) A blocking capacitor 78 is connected in series with the output of the high-frequency stage or the solenoid 79. The blocking capacitor 78 prevents the low-frequency current from the AC voltage source 6 from flowing through the fluorescent tube 1, which would expose the high-frequency stage to the high voltage of the AC power source 6 and thus damage it.
