Beschreibungdescription
Titel: (technische Bezeichnung) Helligkeitsgeregeltes Bremslicht von Kraftfahrzeugen.Title: (technical name) Brightness-controlled brake light from Motor vehicles.
Anwendungsgebiet: (Wiedergabe des Oberbegriffes des Patentanspruches 1) Die Erfindung betrifft die HelligReitsregelung von Kfz-Bremslichtern.Area of application: (Reproduction of the preamble of the patent claim 1) The invention relates to the brightness control of motor vehicle brake lights.
Zweck: Die Helligkeitsregelung soll die Helligkeit der Kfz-Bremslichter den unterschiedlichen Lichtverhältnissen anpassen.Purpose: The brightness control is intended to increase the brightness of the vehicle brake lights adapt to the different lighting conditions.
Tagsüber, besonders bei direkter Sonneneinstrahlung, ist,um ein sicheres Erkennen der Bremslichter zu gewährleisten, eine höhere Helligkeit als nachts erforderlich. Zur Zeit ist die von den gebräuchlichen Bremslichtern von Kfz abgegebene Helligkeit konstant. Bei direkt einstrahlendem Sonnenlicht auf die Bremslichter können dieselben nur noch einen grenzten Kontrast bewirken, so daß die Auffälligkeit verlorengeht, und das plötzliche Aufleuchten der eingeschalteten Bremslichter übersehen wird. During the day, especially in direct sunlight, is to be a safe one Detecting the brake lights to ensure a higher level of brightness than required at night. At the moment, the brightness emitted by the brake lights commonly used in motor vehicles is constant. The brake lights can be exposed to direct sunlight cause only a limited contrast, so that the conspicuity is lost, and the sudden flashing of the brake lights on is overlooked.
Bei Dunkelheit dagegen können zu hell strahlende Bremsleuchten eine Blendung der hinterherfahrenden Verkehrsteilnehmer hervorrufen. In the dark, on the other hand, brake lights that are too bright can cause a Cause dazzling of the road users behind.
Aufgabe: - Der Erfindung liegt die Aufgabe- zugrunde, die Bremslichter von Kfz den jeweiligen Lichtverhältnissen anzupassen, d.h. bei dunkler Umgebung sollen die Bremsleuchten weniger hell strahlen, als bei Sonneneinstrahlung.Task: - The invention is based on the object, the brake lights of vehicles to adapt to the respective light conditions, i.e. in a dark environment the brake lights should shine less brightly than in direct sunlight.
Lösung: Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Helligkeit der Bremslichter gesteuert. wird, derart, daß im Dunkeln weniger Licht von den Bremsleuchten ausgestrahlt wird, als tagsüber bei direkter Sonneneinstrahlung. Die Steuerung erfolgt automatisch durch Einschalten des Fahrlichtes (schwächeres Licht der Bremsleuchten). Die Schaltung muß so gestaltet sein, daß beim Einschalten von Nebelscheinwerfern bzw. Nebelrückleuchten die Helligkeit der Bremslichter gegenüber der des normalen Nacht- bzw. Dunkelheitbetriebes erhöht wird.Solution: This object is achieved according to the invention in that the Brake light brightness controlled. becomes so that in the dark less light emitted by the brake lights than during the day in direct sunlight. The control takes place automatically by switching on the driving light (weaker Brake light). The circuit must be designed so that when switched on of fog lights or rear fog lights compared to the brightness of the brake lights that of normal night or darkness operation is increased.
Weitere Ausgestaltung der Erfindung: Wiedergabe des kennzeichnenden Teils eines Unteranspruches ) Im Weiteren kann die Steuerun@ ele@-tronisch arbeiten. Ein lichtempfindlichei Sensor (Geber) an geeigneter Stelle am Kfz angebracht, übernimmt über ein elektronische Stellglied die Helligkeitssteuerung.Further embodiment of the invention: reproduction of the characteristic Part of a subclaim) In addition, the Steuerun @ ele @ -tronisch can work. A light-sensitive sensor (transmitter) attached to a suitable place on the vehicle takes over the brightness control via an electronic actuator.
Erzielbare Vorteitle: Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß tamsüber bei sehr hellem Sonnenlicht eine wesentlich höhere Lichtleistung der Premslichter die Erkennung derselben verbessert bei Dunkelheit (außer Nebel) vermeidet eine geringere Lichtleistung die Blendung der nachfolgenden. Verkehrsteilnehmer. Dadurch, daß die Helligkeit bei hellem Sonnenlicht stärker sein kann, tr@gt die bessere Erkennung des Bremsvorganges zur.Achievable Advantages: The advantages achieved with the invention exist especially in the fact that tamsüber in very bright sunlight a much higher The light output of the brake lights improves their detection in the dark (except fog), a lower light output avoids dazzling the following. Road users. Because the brightness can be stronger in bright sunlight can, contributes to better recognition of the braking process.
Sicherheit im Straßenverkehr bei. Road safety.
Beschreibung eines oder mehrerer Ausführungsbeispiele: Zwei Ausführungsbeispiele des Erfindung sind in den Zeichnungen dargestellt und werden im folgenden näher beschrieben. Description of one or more exemplary embodiments: Two exemplary embodiments of the invention are illustrated in the drawings and will be described in more detail below described.
Es zeigen: Fig.1: manuell gesteuerte, automatisch wirkende Bremslichtsteuerung.They show: Fig. 1: manually controlled, automatically acting brake light control.
Fig.2: opto-elektronisch gesteuerte, automatisch wirkende Bremslichtsteuerung.Fig. 2: opto-electronically controlled, automatically acting brake light control.
zu Fig. 1: Tagsüb@r, d.h., wenn weder Fahrlicht, Nebellampen und Nebelrückleuchte eingeschaltet sind, wird das Bremslicht mit Maximalleitung (hier zweite, usätzliche stärkere Lampe, Lampe 5 ue 6) arbeiten.to Fig. 1: Tagüb @ r, i.e. if neither driving lights, fog lamps and rear fog lights are switched on, the brake light is with maximum power (here the second, additional stronger lamp, lamp 5 ue 6) work.
Bei Dunkelheit, d.h. wenn nur das Fahrlicht (und evtl. In the dark, i.e. when only the driving lights (and possibly
das Fernlicht) eingeschaltet (Schalter 2) ist (sind), arbeitet das Bremslicht mit Minimalleistung (Lampe 5, nur eine schwächere Lampe wird betrieben). bei Zuschaltung (Schalter 3 u. 4) von Nebellampen bzw. Nebelschlußleuchten wird automatisch die zusatzliche lampe 6 zugeschaltet zu Fig.2: Die Anpassung der Bremslichthelligkeit erfolgt prinzipell wie nach Fig.1. the high beam) is switched on (switch 2) is (are), that works Brake light with minimum power (lamp 5, only a weaker lamp is operated). when switching on (switch 3 and 4) of fog lamps or rear fog lights the additional lamp 6 is switched on automatically to Fig. 2: The adaptation the brake light brightness is basically the same as in Fig. 1.
Die Anpassung für die Umgebungslichtverhältnisse Hell-Dunkel kann hier stufenlos gesteuert werden. Der lichtempfindliche Sensor 7 gibt sein Signal an das Steuergerät 8 , welches die Leistung bzw. The adjustment for the ambient light conditions light-dark can can be continuously controlled here. The light-sensitive sensor 7 gives its signal to the control unit 8, which the power resp.
Helligkeit der Bremslichtlampe 9 steuert. Controls the brightness of the brake light lamp 9.
Ebenso wie nach Fig.1 wird auch hier durch Betätigen der Schalter 3 u. 4 die maximale Helligkeit der Bremslichtlampe bewirkt. As in FIG. 1, by pressing the switch 3 and 4 causes the maximum brightness of the brake light lamp.
Der Unterschied von Fig.2 gegenüber Fig.1 liegt in der stufenlosen individuellen Helligkeitsanpassung. The difference between Fig.2 and Fig.1 is the stepless individual brightness adjustment.
