Description

Die Erfindung betrifft eine Einrichtung an einem Fahrzeug zur Verhinderung der Blendwirkung einer eingebauten Leuchte.The invention relates to a device on a vehicle to prevent the glare of a built-in Lamp.

Verschiedene Leuchten an Kraftfahrzeugen dürfen nur so­ lange eingeschaltet werden, als andere Verkehrsteilnehmer in entgegenkommenden, vorausfahrenden oder nachfolgenden Fahrzeugen nicht geblendet werden. Vielfach werden aber derartige Leuchten absichtlich oder versehentlich in Be­ trieb gehalten, wenn die Voraussetzungen für ihre zuläs­ sige Einschaltung nicht mehr gegeben sind, wenn also bei­ spielsweise Gegenverkehr herrscht oder wenn nach dem Durchfahren eines Nebelgebietes die Sicht wieder frei wird. Besonders besteht die Gefahr der Blendung anderer Verkehrsteilnehmer mit der Nebelschlußleuchte, welche häufig auch bei Witterungsbedingungen eingeschaltet wird, bei denen sie aus Sicherheitsgründen nicht erforderlich ist, z. B. bei leichtem Regen. Die nasse, spiegelnde Fahrbahn führt dann zu erheblicher Sichtbehinderung der nachfolgenden Verkehrsteilnehmer, ebenso wie bei Nebel mit Sichtweiten größer 50 bis 100 m. Durch die dabei ent­ stehende rötlich gefärbte "Wand" ist eine Beobachtung und Erkennung des vorausfahrenden Verkehrs nicht mehr mög­ lich.Different lights on motor vehicles are only allowed this way be switched on for a long time than other road users in oncoming, preceding or following Vehicles are not dazzled. But become many such lights intentionally or accidentally in Be urged if the conditions for their permissible switch-on are no longer given, if at for example, oncoming traffic or if after Driving through a foggy area, the view is clear again becomes. There is a particular risk of dazzling others Road users with the rear fog lamp, which often switched on even in weather conditions, where they are not required for security reasons is, e.g. B. in light rain. The wet, reflective Roadway then leads to considerable visual impairment of the following road users, as well as in fog with visibility greater than 50 to 100 m. Through the ent standing reddish colored "wall" is an observation and Detection of the traffic ahead is no longer possible Lich.

Aufgabe der Erfindung ist es, eine Einrichtung anzugeben, welche automatisch die Fahrzeugleuchten abschaltet, wenn die Voraussetzungen für ihren Betrieb nicht mehr vorlie­ gen. The object of the invention is to provide a device which automatically turns off the vehicle lights when the requirements for their operation no longer existed gene.  

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß mindestens ein Lichtempfangselement mit zur Abstrahlrich­ tung der Leuchte entgegengesetzter Lichteinfallsrichtung am Fahrzeug angeordnet ist, daß das Ausgangssignal des Lichtempfangselements einer Vergleichseinrichtung zuge­ führt ist, welche mit dem Stromkreis der Leuchte gekop­ pelt ist und bei Überschreiten einer vorgegebenen Schwel­ le durch das Ausgangssignal des Lichtempfangselementes die Stromversorgung der Leuchte unterbricht bzw. verrin­ gert.According to the invention, this object is achieved in that at least one light receiving element with the beam direction direction of the luminaire in the opposite direction of light incidence is arranged on the vehicle that the output signal of Light receiving elements a comparison device leads, which is Kopop with the circuit of the lamp pelt and when a predetermined smolder is exceeded le by the output signal of the light receiving element the power supply to the lamp is interrupted or reduced device.

Im einfachsten Fall ist das Lichtempfangselement ein Fo­ toelement mit nachgeschaltetem Schaltverstärker, in des­ sen Ausgangskreis beispielsweise die Erregerwicklung ei­ nes Relais liegt. Erreicht das Signal einen Wert, bei dem das Relais anspricht, unterbricht dieses mit einem Öff­ nerkontakt den Stromkreis der betreffenden Leuchte. Han­ delt es sich um eine Nebelschlußleuchte, so wird das Lichtempfangselement zweckmäßigerweise in eine Rückleuch­ ten-Kombinationsabdeckung des Fahrzeugs integriert und über den Schaltverstärker bzw. die Vergleichseinrichtung mit dem Stromkreis der Nebelschlußleuchten gekoppelt. Soll dagegen das Blenden des entgegenkommenden Verkehrs durch das Fernlicht bzw. durch Nebelscheinwerfer verhin­ dert werden, so wird das Lichtempfangselement am zweckmä­ ßigsten hinter der Frontscheibe des Fahrzeugs, etwa an der nach vorn weisenden Rückseite des Innenspiegels des Fahrzeugs angebracht.In the simplest case, the light receiving element is a Fo toelement with downstream switching amplifier, in the sen output circuit, for example, the excitation winding relay is present. If the signal reaches a value at which the relay responds, interrupts it with an opening contact the circuit of the luminaire in question. Han if it is a rear fog lamp, it will Light receiving element expediently in a back light ten combination cover of the vehicle integrated and via the switching amplifier or the comparison device coupled to the circuit of the rear fog lights. On the other hand, the aim is to dazzle oncoming traffic through the high beam or fog lights be changed, the light receiving element on the expedient most behind the windscreen of the vehicle, for example the forward facing back of the interior mirror of the Vehicle attached.

Zweckmäßig ist es weiterhin, jeweils zwei Lichtempfangs­ elemente mit im wesentlichen gleicher Lichteinfallsrich­ tung vorzusehen, wobei deren Ausgänge konjunktiv, dis­ junktiv oder summierend verknüpft sein können. Auf diese Weise ist es beispielsweise möglich, eine sichere Funk­ tion zu gewährleisten, wenn die Beleuchtungseinrichtung des Fahrzeugs leicht verschmutzt ist und eines der Licht­ empfangselemente mit seinem Ausgangssignal die Schalt­ schwelle nicht erreicht. It is also expedient to have two light receivers each elements with essentially the same light incidence device to provide, the outputs of which are conjunctive, dis can be linked junctively or summing. To this For example, it is possible to have a secure radio tion to ensure when the lighting device the vehicle is slightly dirty and one of the lights receiving elements with its output signal the switching threshold not reached.  

In einer vorteilhaften Weiterbildung der Erfindung ist außerdem vorgesehen, daß als Lichtempfangselement die An­ koppelfläche eines Lichtwellenleiters dient, dessen ent­ gegengesetztes Ende über einen Lichtempfänger an einen nachfolgenden Verstärkerkreis gekoppelt ist. Besonders zweckmäßig ist dabei die Verwendung einer Linse, die als Lichtempfangselement das einfallende Licht auf die An­ kopplungsfläche des Lichtwellenleiters bündelt. Eine der­ artige Linse könnte in einfachster Weise auch bei der Herstellung der Rückleuchten-Abdeckungskombination mit gespritzt werden.In an advantageous development of the invention also provided that the light receiving element to coupling surface of an optical waveguide, the ent opposite end via a light receiver to one subsequent amplifier circuit is coupled. Especially It is expedient to use a lens that Light receiving element the incident light on the on coupling surface of the optical fiber bundles. One of the like lens could be in the simplest way Manufacture of the combination rear light cover be injected.

Die Schaltung kann im übrigen zweckmäßigerweise so ausge­ legt werden, daß z. B. das Fernlicht, welches durch das Licht eines entgegenkommenden Fahrzeuges abgeschaltet wird, nach dem Passieren dieses Fahrzeuges wieder einge­ schaltet wird. Entsprechend kann auch eine Nebelschluß­ leuchte, z. B. nach dem Abbiegen eines nachfolgenden Fahrzeuges, selbsttätig wieder eingeschaltet werden.The circuit can be conveniently so out be placed that z. B. the high beam, which by the The light of an oncoming vehicle is switched off will be switched on again after passing this vehicle is switched. Correspondingly, a short circuit of fog can occur light, e.g. B. after turning a subsequent one Vehicle can be switched on again automatically.

Die Erfindung wird nachfolgend an Ausführungsbeispielen anhand der Zeichnung näher erläutert. Es zeigtThe invention is described below using exemplary embodiments explained in more detail with reference to the drawing. It shows

Fig. 1 zeigt die Frontseite eines Kraftfahrzeugs 1 mit zwei Scheinwerfern 2 sowie Nebelscheinwerfern 3. Um eine Blendung des entgegenkommenden Verkehrs durch das Fern­ licht der Scheinwerfer 2 oder des vorausfahrenden Ver­ kehrs durch die Nebelscheinwerfer 3 zu vermeiden, sind zwei Lichtempfangselemente 4 hinter der Frontscheibe 5, und zwar an der Rückseite eines Innenspiegels 6 angeord­ net. Wenn das einfallende Licht an einem der Lichtemp­ fangselemente oder an beiden, je nach Verknüpfung, einen bestimmten Schwellenwert erreicht, wird über eine nach­ folgende Verstärkerschaltung der Stromkreis der Fern­ licht-Scheinwerfer bzw. der Nebelscheinwerfer unterbro­ chen, obwohl am Armaturenbrett die Schalter für die ent­ sprechenden Scheinwerfer betätigt sind. Die Anordnung der Lichtempfangselemente hinter der Frontscheibe ist deshalb besonders günstig, weil dadurch keine besonderen Schutz­ maßnahmen gegen Witterung oder gegen Verschmutzung erfor­ derlich sind. Da die Frontscheibe durch die Scheibenwi­ scher gereinigt wird, wird das einfallende Licht auch nicht durch übermäßige Verschmutzung abgehalten. Fig. 1 shows the front side of a motor vehicle 1 with two headlamps 2 and fog lamps. 3 In order to avoid dazzling oncoming traffic through the main beam of the headlights 2 or the traffic driving ahead through the fog lights 3 , two light receiving elements 4 are behind the windshield 5 , namely on the back of an inside mirror 6 . If the incident light on one of the light receiving elements or on both, depending on the link, reaches a certain threshold value, the circuit of the high-beam headlights or the fog lights is interrupted via a subsequent amplifier circuit, although the switches for the ent on the dashboard speaking headlights are actuated. The arrangement of the light receiving elements behind the windscreen is particularly favorable because no special protective measures against weather or against pollution are necessary. Since the windscreen is cleaned by the windshield wipers, the incident light is not prevented by excessive contamination.

Fig. 2 zeigt die Rückseite des Fahrzeugs 1 mit einer Rück­ leuchtenkombination 7 auf jeder Seite, wobei die Abdeckun­ gen für Blinker, Rücklicht, Bremslicht, Rückfahrscheinwer­ fer und Reflektor integriert sind. Um das Blenden des nachfolgenden Verkehrs durch eine Nebelschlußleuchte 8 zu vermeiden, sind zwei Lichtempfangselemente 9 jeweils im Bereich des Reflektors 10 vorgesehen und über eine nach­ folgende Verstärker- und Vergleicher-Schaltung mit dem Stromkreis der Nebelschlußleuchte verknüpft. Bei Errei­ chen eines vorgegebenen Schwellenwertes durch das ein­ fallende Licht wird die Nebelschlußleuchte abgeschaltet. Fig. 2 shows the rear of the vehicle 1 with a combination of taillights 7 on each side, the gene gene for indicators, taillight, brake light, Rückfahrscheinwer fer and reflector are integrated. In order to avoid the dazzling of the following traffic by a rear fog lamp 8 , two light receiving elements 9 are provided in the region of the reflector 10 and linked to the circuit of the rear fog lamp via a subsequent amplifier and comparator circuit. When a predetermined threshold is reached by the incident light, the rear fog lamp is switched off.

Das Lichtempfangselement kann unmittelbar als Fotoelement (z. B. Fotodiode oder Fotowiderstand) in die Schlußleuch­ tenabdeckung eingesetzt und unmittelbar mit der Verstär­ kerschaltung verbunden sein. Es ist aber auch möglich, als Lichtempfangselement eine Linse in den Kunststoff der Schlußleuchtenkombination 7 einzuformen und die nach in­ nen gerichtete Seite an eine Lichtleitfaser anzukoppeln, so daß das einfallende Licht in die Lichtleitfaser hin­ ein gebündelt wird.The light receiving element can be used directly as a photo element (e.g. photodiode or photoresistor) in the tail lamp cover and connected directly to the amplifier circuit. But it is also possible to form a lens as a light receiving element in the plastic of the combination of tail lights 7 and to couple the inward-facing side to an optical fiber, so that the incident light is bundled into the optical fiber.

Eine mögliche Schaltungsanordnung für die Auswertung der einfallenden Lichtsignale zeigt Fig. 3. Dabei wird ein Fo­ toelement 11 mit einem Widerstand 12 an eine Spannung U 1 als Spannungsteiler angelegt, deren Mittelabgriff über ei­ ne zweistufige Verstärkerschaltung (Darlington-Schaltung) mit den Transistoren 13 und 14 sowie dem Widerstand 15 zur Auswertung gelangt. Im Ausgangskreis der Verstärkerschal­ tung ist die Erregerwicklung eines Relais 16 angeordnet, parallel zu einer Diode 17, welches beim Erreichen eines beestimmten Stromes anspricht und im Versorgungsstrom­ kreis der Spannung U 2 über den Relaiskontakt 18 die Strom­ versorgung zur Leuchte 19 unterbricht, obwohl der Schal­ ter 20 geschlossen ist. Die Leuchte 19 bedeutet also ent­ weder eine Nebelschlußleuchte 8 aus Fig. 2 oder einen Ne­ belscheinwerfer 3 bzw. die Fernlichtleuchte 2 aus Fig. 1.A possible circuit arrangement for evaluating the incident light signals is shown in FIG. 3. Here, a photo element 11 with a resistor 12 is applied to a voltage U 1 as a voltage divider whose center tap is via a two-stage amplifier circuit (Darlington circuit) with the transistors 13 and 14 and the resistor 15 comes to the evaluation. In the output circuit of the amplifier circuit device, the excitation winding of a relay 16 is arranged in parallel with a diode 17 which responds when a certain current is reached and in the supply current circuit of voltage U 2 via the relay contact 18 interrupts the power supply to the lamp 19 , although the switch ter 20 is closed. The lamp 19 means ent either a rear fog lamp 8 from FIG. 2 or a ne headlight 3 or the high beam lamp 2 from FIG. 1st

Fig. 4 zeigt in einem Blockschaltbild eine Ausführungs­ möglichkeit unter Verwendung einer Lichtwellenleitung. Hierbei fällt das einfallende Licht auf eine Linse 21, welche, wie erwähnt, in die Rückleuchtenkombination inte­ griert sein kann. Das Licht wird in der Linse 21 gebün­ delt und in eine Lichtwellenleitung 22 eingespeist, wel­ che die Lichtsignale einem üblichen Empfänger 23 zuführt. Über den elektrischen Ausgang dieses Empfängers 23 werden dann entsprechende Signale auf der Leitung 24 einer Ver­ stärkerschaltung 25 zugeführt, die genauso oder ähnlich aufgebaut sein kann wie die in Fig. 3 gezeigte Schaltung. Erreicht das einfallende Licht einen vorgegebenen Schwel­ lenwert, wird über den Relaiskontakt 18 der Stromkreis zu den Leuchten 19 unterbrochen. Fig. 4 shows a block diagram of an execution possibility using an optical waveguide. Here, the incident light falls on a lens 21 , which, as mentioned, can be integrated into the rear light combination. The light is bundled in the lens 21 and fed into an optical waveguide 22 , which feeds the light signals to a conventional receiver 23 . Via the electrical output of this receiver 23 , corresponding signals on line 24 are then fed to an amplifier circuit 25 , which can be constructed in the same or a similar manner to the circuit shown in FIG. 3. When the incident light reaches a predetermined threshold value, the circuit to the lights 19 is interrupted via the relay contact 18 .
