Abstract
Description
Anordnung elektronischer Bauteile zur Uberwachung derArrangement of electronic components for monitoring the
rückwärtigen Beleuchtung für Fahrzeuge im Straßenverkehr.rear lighting for vehicles on the road.
Die rückwärtige Brems- und Begrenzungsbeleuchtung -insbesondere für Kraftfahrzeuge im StraBenverkehr- wird mit Hilfe einer Anordnung elektronischer Bauteile auf einwandfreies Funktionieren überwacht.The rear brake and marker lights - especially for Motor vehicles in road traffic will be electronic with the help of an arrangement Components monitored for proper functioning.
Ber Ausfall eines elektrischen Lichtgebers (z.B. Glühlampe) oder einer zwischen der elektrischen Energiequelle (Akkumulator) und den Verbraucher geschaltete elektrische Sicherung wird im Fahrzeuginneren durch ein optisches Signal kennbar gemacht. (optisches Signal = Leuchtdiode) Der Erfindung liegt die Aufgabe zugrunde, die Sicherheit im Straßenverkehr dadurch zu erhöhen, daß der Fahrzeugführer im Stande ist, die rückwärtige Beleuchtung ständig zu überwachen.The failure of an electrical light transmitter (e.g. incandescent lamp) or a connected between the electrical energy source (accumulator) and the consumer electrical fuse is recognizable in the vehicle interior by an optical signal made. (optical signal = light emitting diode) The invention is based on the object to increase the safety in road traffic by the fact that the vehicle driver is able is to constantly monitor the rear lighting.
Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß kein zusätzlicher Verbraucher in Reihe mit der zu überwachenden Leuchte geschaltet wird, da die konduktive Durchgangsimpedanz der Oszillatorspule praktisch null Ohm beträgt. Somit kann die Schaltung als "TVV-freundlich" bezeichnet werden. Außerdem werden Leitungsdrahtbruch, Sicherungsbruch sowie eine fehlerhafte Kontaktgabe am Sicherungahalter oder an Lampenfassungen angezeigt.The advantages achieved with the invention are in particular: that no additional consumer is connected in series with the luminaire to be monitored becomes, since the conductive through impedance of the oscillator coil is practically zero ohms amounts to. The circuit can thus be described as "TVV-friendly". aside from that line wire breakage, fuse breakage and faulty contact on the Fuse holder or lamp sockets displayed.
Ein weiterer Vorteil besteht darin, daß der Fahrzeugführer auch bei längeren Fahrten (z.B. Autobahnfahrt) ständig über den Zustand der rückwärtigen Beleuchtung informiert wird und somit nicht unwesentlich zur Verkehrssicherheit beiträgt.Another advantage is that the driver is also at Longer journeys (e.g. motorway journeys) constantly about the state of the rear Lighting is informed and thus not insignificant for traffic safety contributes.
Ein Ausführungsbeispiel ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben: Figur 1 zeigt einen herkömmlichen Oszillator. Als aktives Element wird ein npn-Transistor verwendet batterie an Masse).An embodiment is shown in the drawing and will described in more detail below: FIG. 1 shows a conventional oscillator. as active element, an npn transistor is used (battery to ground).
In Reihe mit dem Pluspol der Batterie, Sicherung, Lichtschalter und Oszillatorspule liegt eine Glühlampe gegen Masse, entsprechend dem Minuspol der Batterie.In series with the positive terminal of the battery, fuse, light switch and An incandescent lamp is connected to ground, corresponding to the negative pole of the oscillator coil Battery.
Der Oszillator kann durch Sättigungserscheinungen als auch durch einen relativ niederohmigen Nebenschluß -bestehend aus dem Glühfaden der Lampe- nicht anschwingen. Somit wird an den Oszillatorklemmen (Hochpunkt/Tiefpunkt) keine Wechselspannung erzeugt und die, den Oszillatorklemmen angeschaltete Leuchtdiode wird nicht zünden.The oscillator can cause saturation as well as a relatively low-resistance shunt -consisting of the filament of the lamp- not to swing. This means that there is no alternating voltage at the oscillator terminals (high point / low point) generated and the LED connected to the oscillator terminals will not ignite.
Beim Ausfall der Glühlampe (o.ä.) wegen Glühfadenbruch oder fehlerhafter Kontaktgabe der Lampenfassung etc. wird die durch den Lampen-Glühfaden gebildete Dämpfung aufgehoben und folglich der Oszillator anschwingen. Nunmehr wird an den Oszillatorklemmen (Hochpunkt/Tiefpunkt) Wechselspannung erzeugt und die den Oszillatorklemmen angeschaltete Leuchtdiode wird zünden.If the bulb fails (or similar) due to a broken filament or a faulty one Contact of the lamp socket etc. is that formed by the lamp filament Damping is canceled and consequently the oscillator starts to oscillate. Now the Oscillator terminals (high point / low point) AC voltage generated and the oscillator terminals switched on LED will ignite.
Beim Ausfall der Lampensicherung durch Bruch oder fehlerhafter Kontaktgabe wird die Leuchtdiode, die mit ihrer Anode an dem Pluspol der Batterie liegt, mit Hilfe des Glühfadens der Lampe kathodenseitig an Masse -entsprechend dem Minuspol der Batterie- elektrisch verbunden, wodurch die Leuchtdiode zündet.If the lamp fuse fails due to breakage or faulty contact the light-emitting diode, which is connected to the positive pole of the battery with its anode, with Using the filament of the lamp on the cathode side to ground - corresponding to the negative pole the battery is electrically connected, causing the light-emitting diode to ignite.
