Description
Beleuchtungseinrichtung für das Armaturenbrett von Kraftfahrzeugen mittels gleichzeitig als Kerzenprüfer dienender Leuchtröhren Es ist bekannt, das Armaturenbrett von Kraftwagen durch von der Zündmaschine des Motors aus gespeisten Hochspannungsröhren zu beleuchten. Ebenso ist es bekannt, derartige Röhren zur Kontrolle der Tätigkeit der Zündkerzen zu verwenden, indem eine Röhre mit den einzelnen Kerzen in Verbindung gebracht werden kann oder für jede einzelne Kerze eine besondere Funkenstrecke vorgesehen ist. Diese Einrichtungen lassen sich jedoch zur Beleuchtung des Armaturenbrettes nicht verwenden, da die Funken in zu lange dauernden Perioden erscheinen und so, besonders bei langsamer Drehzahl des Motors, ein den Führer störendes Flackern ergeben würden.Lighting device for the dashboard of motor vehicles by means of fluorescent tubes also serving as candle tester It is known that Automobile dashboards powered by the engine's blasting machine Illuminate high voltage tubes. It is also known to control such tubes To use the activity of the spark plugs by placing a tube with the individual plugs can be associated or a special spark gap for each individual candle is provided. However, these devices can be used to illuminate the dashboard do not use, as the sparks appear in periods that are too long and so, especially when the engine is running at a slow speed, a flickering disturbing the driver can result would.
Gemäß der Erfindung wird das Flackern bei Mehrzylindermaschinen dadurch erheblich vermindert, daß jeweils von mehreren Kerzen die Funkenstrecke durch die gleiche, zur Beleuchtung dienende Röhre führt. Um hierbei dennoch die Kontrolle über die Tätigkeit der einzelnen Kerzen zu behalten, sind an den Enden der Röhre Abzweigungen vorgesehen, die jeweils mit nur einer Kerze- in Verbindung -stehen, so daß. von .diesen Abzweigungen aus erkannt werden kann, welche Kerze gestört ist.According to the invention, the flickering in multi-cylinder machines is eliminated considerably reduced that each of several candles the spark gap through the same tube used for lighting leads. In order to still be in control To keep track of the activity of each candle are at the ends of the tube Branches are provided, each of which is connected to only one candle, so that. from .these branches it can be recognized which candle is faulty.
Die Zeichnung zeigt beispielsweise Anordnungen der Erfindung, und zwar zeigen Abb. i ein Armaturenbrett mit parallel geschalteten Leuchtröhren, Abb. a eine weitere Ausführung der Leuchtröhren.The drawing shows, for example, arrangements of the invention, and although Fig. i shows a dashboard with fluorescent tubes connected in parallel, Fig. a another version of the fluorescent tubes.
Auf dem Armaturenbrett a befinden sich in Abb. i die vier Leuchtröhren r, die an den spannungfühnenden Pol der Kerzen k angeschlossen sind. Diese werden vom Verteiler v gespeist. Die Leuchtröhren r sind in einer gemeinsamen Röhre g zusammengefaßt, an deren anderem Ende sich die mit der Masse M verbundene Nulleiterelektrode e befindet. Diese Zusammenfassung hat den Vorteil, daß jeder Zündfunke die Röhre g zum Leichten bringt, so daß das Licht in dieser entsprechend der Anzahl der Kerzen um ein Vielfaches gleichmäßiger ist als in den Einzelröhren r.On the dashboard a there are in Fig. I the four fluorescent tubes r, which are connected to the voltage-carrying pole of the candles k. These are fed from distributor v. The fluorescent tubes r are combined in a common tube g, at the other end of which the neutral electrode e connected to the ground M is located. This combination has the advantage that each ignition spark makes the tube g light, so that the light in this, corresponding to the number of candles, is many times more uniform than in the individual tubes r.
Bei der Ausführungsform gemäß Abb. a befindet sich die Sammelelektrode e in der Mitte und strahlt nach beiden Seiten des Armaturenbrettes zu den Einzelröhren r aus. D'ie in den Einzelröhren angebrachten Elektroden b können in Buchstaben- oder Zahlenform ausgeführt sein, wodurch die mit den Elektroden in Verbindung stehende Kerze gekennzeichnet ist. Solange die betreffende Ziffer periodisch .aufleuchtet (bei hoher Drehzahl nahezu gleichmäßig), ist die Gewähr dafür gegeben, daß die betreffende Kerze Zündstrom - erhält, und daß kein Kurzs,chluß in ihr vorliegt. Bei Verölung der Kerze oder Abbrechen der Zündpole, kurz wenn an der Kerze kein - Funke überspringen kann, so beeinflußt dies auch die parallel geschaltete Röhre insofern, als infolge der fehlenden Kapazität, die sonst bei normalem Zünden der vom Pol der Kerze zur Masse des Motors überspringende Funke ergibt, die Leuchtröhre nur schwach, kaum sichtbar leuchtet.In the embodiment according to Fig. A, the collecting electrode is located e in the middle and radiates on both sides of the dashboard to the individual tubes Out. The electrodes b attached to the individual tubes can be written in letters or numerical form, whereby the associated with the electrodes Candle is marked. As long as the relevant digit lights up periodically (almost uniformly at high speed), there is a guarantee that the relevant Candle ignition current - receives, and that there is no short circuit in it. With oil of the candle or breaking off the ignition poles, briefly if there is no spark on the candle can, this also affects the parallel connected tube insofar as as a result the lack of capacity, which would otherwise occur from the pole of the candle to the The mass of the motor results in skipping sparks, the fluorescent tube only weakly, hardly at all visibly lights up.
Die Leuchtröhren können eingekapselt ausgeführt sein, so daß sie gegen Stöße unempfindlich sind, und z. B. in Gummipolsterung eingebettet. Die Kapselung wird vorteilhaft so ausgeführt, daß der Lichtschein der Röhren abwärts auf die Instrumente strahlt und den Fahrer nicht blendet.The fluorescent tubes can be encapsulated so that they against Shocks are insensitive, and z. B. embedded in rubber upholstery. The encapsulation is advantageously carried out so that the light from the tubes down onto the instruments shines and does not dazzle the driver.
