Bei der Ansteuerung verteilter und/oder unterschiedlicher Leuchtmitteltypen stellt sich das Problem der Synchronisation, wenn diese getaktet betrieben werden.at the control of distributed and / or different types of lamps the problem of synchronization arises when this is clocked operate.
Der Erfindung liegt daher das technische Problem zugrunde, eine Blinkleuchtenanordnung für ein Kraftfahrzeug zu schaffen, die mindestens eine Glühlampe und mindestens eine LED als Leuchtmittel umfasst, bei der die Synchronität der Leuchtmittel zueinander verbessert ist, sowie ein zugehöriges Verfahren zur Ansteuerung zur Verfügung zu stellen.The The invention is therefore based on the technical problem of a turn signal arrangement for a Motor vehicle to create at least one light bulb and comprises at least one LED as a lamp, in which the synchronism of the lamps with each other is improved, as well as an associated method available for control to deliver.
Die Lösung des technischen Problems ergibt sich aus den Gegenständen mit den Merkmalen der Patentansprüche 1 und 8. Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.The solution of the technical problem arises from the items the features of the claims 1 and 8. Further advantageous embodiments of the invention result itself from the subclaims.
Hierzu wird der Glühlampe eine Vorheizeinrichtung zugeordnet, mittels derer die Glühlampe auf eine Temperatur aufheizbar ist, die unterhalb der Glühtemperatur der Glühlampe liegt. Die Erfindung geht dabei von der Erkenntnis aus, dass die unterschiedlichen Anstiegszeiten von LED's und Glühlampen der größte Faktor bei der Ursache von Asynchronitäten beim Blinken sind und weitaus stärker ins Gewicht fallen als beispielsweise Laufzeitunterschiede aufgrund unterschiedlicher Leitungslängen und/oder von Toleranzen der unterschiedlichen Leuchtmittel.For this becomes the light bulb assigned a preheating device by means of which the incandescent lamp is placed on a Temperature can be heated, which is below the glow temperature of the incandescent lamp. The invention is based on the knowledge that the different Rise times of LEDs and light bulbs the biggest factor at the cause of asynchrony are blinking and much stronger are considered to be due, for example, to differences in maturity different line lengths and / or of tolerances of the different illuminants.
In einer bevorzugten Ausführungsform sind die LED's in einem Außenspiegel und die Glühlampen in einer vorderen und/oder hinteren Blinkleuchte angeordnet. Die Verwendung von LED's im Außenspiegel hat den Vorteil, dass die LED's weniger Platz erfordern als Glühlampen, so dass eine größere Ausführung des Außenspiegels zum Unterbringen der Blinkleuchte vermieden wird.In a preferred embodiment the LEDs are in an outside mirror and the light bulbs arranged in a front and / or rear turn signal lamp. The Use of LEDs in the outside mirror has the advantage that the LED's require less space than incandescent lamps, so that a larger version of the outside mirror to accommodate the flashing light is avoided.
In einer weiteren bevorzugten Ausführungsform wird die Helligkeit der LED's und der Glühlampen durch geeignete Messinstrumente gemessen. Ein Regler bestimmt aus den Messwerten die Blinkfrequenzen. Die Vorheizeinrichtung wird durch den Regler so gesteuert, dass die Blinkfrequenzen annähernd gleich sind. Die Verwendung eines Reglers vermeidet mehrere Probleme, die bei Verwendung einer konstanten Vorheizleistung entstehen würden. Zum einen führt das Blinken im Laufe des Betriebs der Blinkleuchte zu einer zusätzlichen Erwärmung des Glühfadens, so dass bei Verwendung einer konstanten Vorheizleistung die Ansprechzeit der Glühlampe sinkt. Dieser Effekt kann durch Herunterregeln der Vorheizeinrichtung ausgeglichen werden. Zum anderen besitzen die verwendeten Bauteile gewisse Toleranzen, die durch den Regler ebenfalls ausgeglichen werden können. Auch andere Ursachen für unterschiedliche Blinkfrequenzen, wie zusätzliche Lasten am Bordnetz, können durch den Regler kompensiert werden.In a further preferred embodiment the brightness of the LED's and the light bulbs measured by suitable measuring instruments. A controller determines the flashing frequencies. The preheater will controlled by the controller so that the flashing frequencies are approximately the same are. Using a regulator avoids several problems that would arise when using a constant preheating power. To the leads one the blinking during the operation of the turn signal lamp to an additional one Warming the filament, so that when using a constant preheating power the response time the light bulb sinks. This effect can be achieved by reducing the preheater be balanced. On the other hand, the components used certain tolerances, which are also compensated by the controller can be. Other causes for different flashing frequencies, such as additional loads on the vehicle electrical system, can can be compensated by the controller.
In einer weiteren bevorzugten Ausführungsform wird das Einschalten der LED's durch ein Verzögerungsglied verzögert. Diese Ausführungsform ist insbesondere dann von Vorteil, wenn die Differenz der Ansprechzeiten so groß ist, dass das Vorheizen der Glühlampen nicht ausreicht, um die Blinkfrequenzen einander anzugleichen.In a further preferred embodiment will turn on the LED's through a delay element delayed. This embodiment is particularly advantageous if the difference in response times is so big that preheating the light bulbs not enough to match the flashing frequencies.
Die Messinstrumente für die Messung der Helligkeit sind bevorzugt als Photodioden ausgebildet. Dies ist von Vorteil, da die Messinstrumente die Blinkleuchten nicht nennenswert vergrößern sollen, so dass eine möglichst Platz sparende Ausführungsform erwünscht ist. Diese Bedingung wird von Photodioden erfüllt. Werden mehrere LED's verwendet, beispielsweise in Form eines Arrays, so kann ein Messinstrument dem ganzen Array zugeordnet sein. In diesem Fall mittelt die Messeinrichtung die gegebenenfalls unterschiedlichen Ansprechzeiten der LED's.The measuring instruments for measuring the brightness are preferably designed as photodiodes. This is advantageous because the measuring instruments are the Indicator lights should not enlarge significantly, so that a space-saving embodiment is desirable. This condition is met by photodiodes. If several LEDs are used, for example in the form of an array, a measuring instrument can be assigned to the entire array. In this case, the measuring device averages the possibly different response times of the LEDs.
In einer bevorzugten Ausführungsform ist die Vorheizeinrichtung als Potentiometer ausgebildet. Dabei sind die Glühlampe und das Potentiometer in Reihe geschaltet, so dass die Vorheizspannung an der Glühlampe durch das Potentiometer geregelt werden kann.In a preferred embodiment the preheater is designed as a potentiometer. there are the light bulb and the potentiometer connected in series so that the preheating voltage on the light bulb can be regulated by the potentiometer.
In einer weiteren bevorzugten Ausführungsform ist die Vorheizeinrichtung als zusätzliche Stromquelle ausgebildet, die parallel zur Glühlampe angeordnet ist. Die Vorheiztemperatur kann so durch Regeln der Stromquelle eingestellt werden.In a further preferred embodiment the preheating device is designed as an additional power source, the parallel to the light bulb is arranged. The preheating temperature can be controlled by regulating the power source can be set.
In einer weiteren bevorzugten Ausführungsform gibt der Regler ein Warnsignal, wenn eines der Messinstrumente den Ausfall einer Blinkleuchte registrieren sollte.In a further preferred embodiment the controller gives a warning signal if one of the measuring instruments detects the Failure of a flashing light should register.
Die LED's werden vorzugsweise durch ein Kühlblech oder andere geeignete Kühleinrichtungen gekühlt, um deren Verlustwärme abzuführen, da die Helligkeit bei steigender Temperatur abnimmt.The LEDs are preferred through a heat sink or other suitable cooling devices their heat loss dissipate, because the brightness decreases with increasing temperature.
Die Erfindung wird nachfolgend anhand eines bevorzugten Ausführungsbeispiels näher erläutert. Die Fig. zeigen:The In the following, the invention is illustrated by a preferred embodiment explained in more detail. The Show:
