Abstract

An optical warning system has a colored identification or marker light, in which the identification light has a light source and a color filter. The color filter is formed by at least one back-lighting liquid crystal display (LCD) or specifically by at least one self-lighting LCD or by a LCD- of TFT-display.

Description

Die Erfindung betrifft ein optisches Warnsystem für ein Kraftfahrzeug mit einer farbigen Kennleuchte.The invention relates to an optical Warning system for a motor vehicle with a colored beacon.

Bekannte optische Warnsysteme weisen üblicherweise Kennleuchten mit jeweils einfarbigen Farbfiltern auf; zur Darstellung verschiedenfarbiger Lichtsignale können solche Leuchten mit wechselbaren farbigen Lichtscheiben ausgestattet sein. Durch den für den Lichtscheibenwechsel jeweils erforderlichen Aufwand sind solche Leuchten hinsichtlich der Darstellung verschiedenfarbiger Signale nur wenig flexibel einsetzbar.Known optical warning systems usually have Beacons with single-color filters; for illustration Different colored light signals can be used with interchangeable lights colored light panes. By the for the lens change Such lights are required in each case the representation of different colored signals can only be used with little flexibility.

Aus der deutschen Offenlegungsschrift DE 100 59 844 A1 ist eine Mehrfach-Warnleuchte für verschiedenfarbige Signallichter bekannt, die Anordnungen aus unterschiedlich farbigen Lichtquellen aufweist. Eine solche Leuchte ist aufgrund der Vielzahl benötigter Einzellichtquellen relativ aufwendig.From the German published application DE 100 59 844 A1 a multiple warning light for differently colored signal lights is known, which has arrangements of differently colored light sources. Such a lamp is relatively expensive due to the large number of individual light sources required.

Es ist die Aufgabe der Erfindung ein optisches Warnsystem für ein Kraftfahrzeug mit einer farbigen Kennleuchte zu schaffen, welches flexibel wählbar die Darstellung verschiedener Farben und überdies die Darstellung von Symbol- und Textinformationen ermöglicht.It is the object of the invention an optical warning system for to create a motor vehicle with a colored beacon, which flexibly selectable the representation of different colors and also the representation of Icon and text information enabled.

Diese Aufgabe wird erfindungsgemäß entweder dadurch gelöst, daß das Farbfilter der Kennleuchte durch mindestens ein hinterleuchtbares oder alternativ die Kennleuchte selbst durch mindestens ein selbstleuchtendes Flüssigkristalldisplay ausgebildet ist.This task is either solved by that this Color filter of the beacon by at least one backlit or alternatively the beacon itself by at least one self-illuminating liquid crystal display is trained.

Der Erfindung liegt die Idee zugrunde, zur Ausbildung der Kennleuchte ein oder mehrere Flüssigkristalldisplays zu verwenden, wie sie insbesondere als Monitore für Notebooks eingesetzt werden. Solche Displays sind derzeit noch relativ kostspielig, wobei sich die hohen Kosten insbesondere daraus ergeben, daß Computermonitore weitgehend frei von Pixelfehler sein müssen, wodurch die Ausschußquote bei der Herstellung solcher Displays sehr hoch ist.The invention is based on the idea to form the beacon one or more liquid crystal displays to use as they are especially used as monitors for notebooks be used. Such displays are currently still relatively expensive, although The high cost arises in particular from the fact that computer monitors largely must be free of pixel errors, whereby the reject rate is very high in the manufacture of such displays.

Vorteilhaft ist, daß für die erfindungsgemäße Anwendung die Anforderungen bezüglich der Abwesenheit solcher Pixelfehler recht gering sind, so daß hier Displays verwendet werden können, die hinsichtlich einer Anwendung als Monitor als Ausschuß gelten und die daher kostengünstig erhältlich sind.It is advantageous that for the application according to the invention the requirements regarding the absence of such pixel errors are quite small, so that here displays can be used which are regarded as a committee with regard to use as a monitor and therefore inexpensive available are.

Mit einem oder mehreren solcher Displays kann nun ein vielfältig einsetzbares optisches Warnsystem realisiert werden.With one or more such displays now a diverse usable optical warning system can be realized.

So kann das mindestens eine Display eine farbige Kennleuchte realisieren, wobei die Farbe (oder auch Anordnungen von mehreren Farben) mittels einer elektronischen Ansteuerschaltung einfach auswählbar ist. Auch können Lauflichteffekte, insbesondere umlaufendes farbiges oder weißes Licht durch umlaufendes Transparentschalten des Displays leicht realisiert werden.So that can be at least one display realize a colored beacon, the color (or Arrangements of several colors) by means of an electronic control circuit easily selectable is. Can too Running light effects, in particular circulating colored or white light all-round transparent switching of the display can be easily realized.

Über die reine Leuchtenfunktion hinaus können auch Lauftexte oder variable Symbol- oder Textfelder auf dem Display dargestellt werden.about The pure luminaire function can also include scrolling texts or variable Symbol or text fields can be shown on the display.

Als Displays können sowohl selbstleuchtende als auch hinterleuchtete LC- oder TFT-Displays eingesetzt werden, wobei zur Hinterleuchtung beliebige Lichtquellen (LED-Halogen-, Xenonlampen) verwendet werden können.Displays can be both self-illuminating as well as backlit LC or TFT displays are used, whereby for Any type of light source (LED halogen, xenon lamps) can be used can.

Zur Ansteuerung der Displays kann eine, evtl. mit geringfügigen Ergänzungen versehene, handelsübliche mikroprozessorgesteuerte Pixelansteuerung verwendet werden, wie man sie auch in Computern eingebaut findet (z. B. „VGA-Karten"). Die auf dem Display darzustellenden Farb-, Symbol- und Textinformationen können vorteilhaft in einem nichtflüchtigen Speicher abgelegt sein. Für einfache Einfarbendarstellung ist es im allgemeinen sogar ausreichend, wenn die Ansteuerelektronik den Displays einfache Schaltspannungen zuführen kann.Can be used to control the displays one, possibly with minor additions provided, commercially available microprocessor-controlled pixel control can be used, such as they can also be found in computers (eg "VGA cards"). The ones on the display Color, symbol and text information to be displayed can be advantageous in a non-volatile Be stored. For simple single-color representation is generally sufficient, if the control electronics show simple switching voltages respectively can.

Im folgenden werden drei schematisch dargestellte Ausführungsbeispiele des erfindungsgemäßen optischen Warnsystems anhand der Zeichnung dargestellt.The following are three schematic illustrated embodiments of the optical according to the invention Warning system shown using the drawing.

Die drei Skizzen zeigen jeweils eine Anordnung aus einer Lichtquelle und einem hinterleuchteten Flüssigkristalldisplay in einer Draufsicht von oben. In der 1 ist das Display zylinderförmig um die Lichtquelle herum angeordnet. Darum befindet sich eine ebenfalls zylinderförmige Linse oder eine Lichtscheibe zum Schutz des Displays vor mechanischen Einwirkungen.The three sketches each show an arrangement of a light source and a backlit liquid crystal display in a top view from above. In the 1 the display is arranged in a cylindrical shape around the light source. That is why there is also a cylindrical lens or a lens to protect the display from mechanical influences.

Die 2 zeigt eine entsprechende Anordnung aus mehreren, hier dreieckig zusammengefügten Displays und die 3 zeigt als einfachste Ausführung ein flächig ausgeführtes Display mit einer Lichtquelle zur Hinterleuchtung.The 2 shows a corresponding arrangement of several, here triangular displays and the 3 The simplest version shows a flat display with a light source for backlighting.

Werden statt hinterleuchteter selbstleuchtende Displays vorgesehen, so kann die Lichtquelle eingespart werden.Are instead of backlit self-illuminating Provided displays, so the light source can be saved.
