Abstract

The photosensitive detector, fitted to the windscreen, converts light into electrical signals which are used in an electronic circuit to operate a relay for switching the lamps according to the variations in ambient light. Interfacing wavelengths are filtered out to maintain a defined switching point, whose sensitivity can be adjusted continuously throughout its range. The switching can also be delayed by adjustment of the switching point independently of sensitivity. USE/ADVANTAGE - For automatic can lamp dimming, with increased safety and driver's comfort.

Description

Dämmerungsschaltungen sind elektronische Schaltungen, die viel­ seitig einsetzbar sind. Sie haben die Aufgabe, bei Abdunke­ lung am Einsatzort ein elektrisches Element zu schalten.Twilight circuits are electronic circuits that do a lot can be used on both sides. You have the job at Abdunke switch an electrical element at the place of use.

Stand der Technik ist, daß Dämmerungsschaltungen im Kfz-Be­ reich für Fahrzeuge entwickelt wurden, deren Schaltpunkte sehr stark differieren.State of the art is that twilight circuits in Kfz-Be were richly developed for vehicles whose switching points differ very much.

Aufgabe dieser Entwicklung ist es, Autofahrern während der Fahrt, durch automatisches Ein- und Ausschalten der Fahrzeug­ beleuchtung bei Dämmerung oder Tunnelfahrten, mehr Sicher­ heit zu verleihen.The task of this development is to help motorists during the Drive, by automatically switching the vehicle on and off lighting at dusk or tunnel driving, more safe to lend.

Mit Hilfe eines lichtempfindlichen Sensors, der von innen vor der Windschutzscheibe des Kraftfahrzeuges angebracht wird, werden die Lichtwellen in eine elektrische Größe um­ gewandelt. Diese elektrische Größe bewirkt in einer elektro­ nischen Schaltung das Schalten eines Relais und damit das Ein- und Ausschalten der Fahrzeugbeleuchtung. Um einen defi­ nierten Schaltpunkt zu erhalten, werden störende Lichtwellen aus dem Lichtspektrum mittels eines optischen Filters aus­ gefiltert. Die Empfindlichkeit des Schaltpunktes für die EL Schaltung kann stufenlos eingestellt werden. Unabhängig von der Empfindlichkeit der Schaltung kann man ferner den Schalt­ punkt so einstellen, daß die Ein- und Ausschaltung verzögert erfolgt.With the help of a light-sensitive sensor that works from the inside attached in front of the windshield of the motor vehicle the light waves are converted into an electrical quantity changed. This electrical quantity results in an electro African circuit, the switching of a relay and thus that Switching the vehicle lighting on and off. To defi Obtaining the switching point will be disruptive light waves from the light spectrum using an optical filter filtered. The sensitivity of the switching point for the EL Circuit can be adjusted continuously. Independent of the sensitivity of the circuit can also be the circuit Set the point so that switching on and off is delayed he follows.

Die Versorgungsspannung der elektronischen Schaltung wird mit dem Zündschlüssel geschaltet und ist der Betriebsspan­ nung des Kraftfahrzeuges angepaßt. The supply voltage of the electronic circuit will switched with the ignition key and is the operating chip adjusted the motor vehicle.  

Die Schaltkontakte des Relais werden so geschaltet, daß sie parallel zum Beleuchtungsschalter liegen. Somit ist auch weiterhin neben der Automatik die bisherige Funktion des Be­ leuchtungsschalters gewährleistet.The switching contacts of the relay are switched so that they lie parallel to the lighting switch. So is also in addition to the automatic, the previous function of the Be lighting switch guaranteed.

Der Fahrzeuglenker hat so die Möglichkeit, in Grenzfällen die Fahrzeugbeleuchtung auch manuell einschalten zu können.The vehicle driver has the possibility in borderline cases also switch on the vehicle lighting manually can.
