Abstract
Description
Warnleuchten sind u. a. im Straßenverkehr häufig anzutreffen und haben zweckbedingt eine hohe Lichtstärke, womit sie jedoch gleichzeitig eine gefährliche Blendungsquelle bilden. Dies gilt in besonderem Maße bei den an Fahrzeugen vorhandenen Nebelschlußleuchten für die nachfolgenden und die überholenden Fahrzeugführer. Verstärkt wird diese Blendungsgefahr noch durch die stets wechselnden Nebel-/Sichtverhältnisse, für die Nachlässigkeit der Fahrzeugführer, die Nebelschlußleuchte nicht nur situationsgerecht ein- bzw. auszuschalten und durch die unvermeidliche Tatsache, daß die Lichtstärke quadratisch vom Abstand abhängt. Der Entwicklung lag die Aufgabe zugrunde, die Blendungsgefahr von insbesondere Nebelschlußleuchten zu mindern ohne deren Nutzen zu schmälern und gleichzeitig eventuelle menschliche Nachlässigkeit zu kompensieren.Warning lights are u. a. frequently encountered in traffic and purposefully have a high light intensity, but with it at the same time form a dangerous source of glare. This applies particularly to those on vehicles Rear fog lights for the following and the overtaking Driver. This risk of glare is intensified due to the constantly changing fog / visibility conditions, for the negligence of the driver, the rear fog lamp not only switch on and off according to the situation and by the inevitable fact that the light intensity is square depends on the distance. The development was based on the task the risk of glare from rear fog lights in particular to reduce without reducing their benefits and at the same time to compensate for any human negligence.
Gelöst wurde die Aufgabe durch eine automatisch wirkende Helligkeitssteuerung für z. B. Nebelschlußleuchten, die in einer bevorzugten Ausführung als Zweipol ausgeführt ist und damit einfach in die Stromzuführung eingeschleift werden kann, so daß auch eine problemlose Nachrüstung bei gebrauchten Fahrzeugen möglich ist.The task was solved by an automatic one Brightness control for e.g. B. rear fog lights in a preferred embodiment is designed as a bipolar and thus can simply be looped into the power supply, so that it can also be easily retrofitted to used ones Vehicles is possible.
Die Fig. 1 zeigt das Blockschaltbild der erfindungsgemäßen Helligkeitssteuerung (1), mit einem steuerbaren Verstärker (10) und einem Detektor (20). Im einfachsten Fall besteht dieser Detektor (20) aus einem Lichtempfänger, dessen Rich charakteristik - z. B. mit einer ihm vorgesetzten Zylinderlinse - so beschaffen ist, daß er in der Vertikalen einen nur geringen und in der Horizontalen einen breiten Öffnungswinkel hat. Damit kann ein solcher z. B. am Fahrzeugheck angebrachter Lichtempfänger (20) auf das Scheinwerferlicht nachfolgender Fahrzeuge bestimmungsgemäß reagieren und ein entsprechendes Steuersignal an den Verstärker (10) geben, der somit die Helligkeit der Nebelschlußleuchte (30) umso mehr herabregelt, je mehr sich ein nachfolgendes Fahrzeug nähert und je besser die Sichtverhältnisse sind. Fig. 1 shows the block diagram of the brightness control ( 1 ) according to the invention, with a controllable amplifier ( 10 ) and a detector ( 20 ). In the simplest case, this detector ( 20 ) consists of a light receiver, the rich characteristic - z. B. with a cylindrical lens placed in front of him - is such that it has only a small opening angle in the vertical and a wide opening angle in the horizontal. So that such. B. attached to the rear of the vehicle light receiver ( 20 ) to the headlights of subsequent vehicles as intended and give a corresponding control signal to the amplifier ( 10 ), which thus regulates the brightness of the rear fog lamp ( 30 ) the more the closer a following vehicle approaches and ever the visibility is better.
Das bedeutet in der praktischen Anwendung, daß die Nebelschluß leuchte bei weit entfernt nachfolgenden Fahrzeugen sowie bei sehr dichtem Nebel ihre maximale Helligkeit hat, dagegen bei aufklarender Sicht und/oder sich annäherndem Fahrzeug deren Lichtstärke entsprechend vermindert und somit eine wesentliche Verringerung der Blendungsgefahr erreicht wird.In practical application, this means that the fog is closed light up on vehicles far behind as well as on very dense fog has its maximum brightness clear view and / or approaching vehicle Luminous intensity reduced accordingly and thus an essential Reduction of the risk of glare is achieved.
