Die Erfindung bezieht sich auf eine Vorrichtung zum Anzeigen von Meßwerten und Informationen auf der Frontscheibe von Land-, Wasser- und Luftfahrzeugen im Gesichtsfeld des Fahrzeugführers mit einer Projektionseinrichtung und einem an der Frontscheibe angeordneten Schirm.The invention relates to a device for displaying measured values and information on the windshield of Land, water and air vehicles in the driver's field of vision with a projection device and an on the screen arranged on the windshield.
Zum Anzeigen von Meßwerten an der Frontscheibe von Fahrzeugen sind bereits eine Vielzahl von Vorrichtungen bekannt. Diese umfassen eine Projektionseinrichtung mit einer Glühlampe, einem optischen Linsensystem und einem im Strahlengang angeordneten feststehenden oder beweglichen, lichtdurchlässigen Bild mit beliebigen Symbolen und einen Schirm an der Windschutzscheibe, auf den das jeweilige Bild dauernd oder lediglich im Warnfall projiziert wird. Der Schirm besteht meist aus einem lichtundurchlässigen oder, was seltener der Fall ist, aus einem teildurchlässigen Spiegel, der so im Gesichtsfeld des Fahrzeugführers angeordnet ist, daß dieser das sich vor der Frontscheibe abspielende Verkehrsgeschehen und die Meßwerte und Informationen mit einem Blick erfassen kann.A large number of devices are already known for displaying measured values on the windshield of vehicles. These comprise a projection device with an incandescent lamp, an optical lens system and one arranged in the beam path fixed or moving, translucent image with any symbols and a screen on the windshield, on which the respective image is projected continuously or only in the event of a warning. The screen is there usually from an opaque mirror or, which is less often the case, from a partially transparent mirror, which is so im The vehicle driver's field of vision is arranged so that he can see the traffic situation in front of the windshield and can grasp the measured values and information at a glance.
Diese bekannten Vorrichtungen haben den Nachteil, daß bei Verwendung eines lichtundurchlässigen Spiegels dieser zur Vermeidung einer Sichtbehinderung des Fahrzeugführers relativ klein gewählt werden muß und infolgedessen die Ablesung der Meßwerte und Informationen erschwert ist. Aufgrund der kleinen Spiegelabmessungen kann darüber hinaus nur eine begrenzte Anzahl von Meßwerten und Informationen auf diese Weise angezeigt werden. Bei Verwendung eines teildurchlässigen Spiegels können zwar größere Spiegelabmessungen gewählt werden, so daß mehr Meßwerte und Informationen darstellbar sind oder bei gleicherThese known devices have the disadvantage that when using an opaque mirror this for To avoid obstructing the view of the vehicle driver must be chosen to be relatively small and, as a result, the reading of the Measured values and information is difficult. Due to the small dimensions of the mirrors, only a limited number can be used of measured values and information are displayed in this way. When using a partially transparent mirror you can Although larger mirror dimensions are selected so that more measured values and information can be displayed or with the same
- 2 5098U/1194 - 2 5098U / 1194
Anzahl der Meßwerte und Informationen der Abbildungsmaßstab vergrößert werden kann, jedoch werden die Abbildungen blasser und sind insbesondere bei großer Umgebungshelligkeit, wie sie beispielsweise an sonnigen Tagen oder nachts bei direkter Beleuchtung der Frontscheibe durch entgegenkommende Fahrzeuge auftritt, nur sehr schlecht ablesbar.The number of measured values and information on the image scale can be enlarged, but the images become paler and are particularly important when the ambient light is very bright, for example on sunny days or at night with direct lighting the windscreen occurs by oncoming vehicles, is very difficult to read.
Diese Nachteile sollen durch die Erfindung beseitigt werden. Es ist daher Aufgabe der Erfindung, eine Anzeigevorrichtung zu schaffen, mit der eine Vielzahl von Meßwerten und Informationen in einem eine leichte Ablesung erlaubenden Abbildungsmaßstab und Kontrast ohne Sichtbehinderung des Fahrzeugführers an der Frontscheibe dargestellt werden kann.These disadvantages are intended to be eliminated by the invention. It is therefore the object of the invention to provide a display device to create a multitude of measured values and information in an easy-to-read image scale and contrast can be displayed on the windshield without obstructing the driver's view.
Ausgehend von der eingangs beschriebenen Vorrichtung wird diese Aufgabe erfindungsgemäß dadurch gelöst, daß die Projektionseinrichtung eine ultraviolette Strahlen emittierende Lichtquelle enthält und als Schirm eine in. unbeleuchtetem Zustand gut durchsichtige phototrope oder photochrome Schicht vorgesehen ist.Based on the device described at the outset, this object is achieved according to the invention in that the projection device contains a light source emitting ultraviolet rays and an in. unilluminated screen as a screen State good transparent photochromic or photochromic layer is provided.
Die Erfindung geht von dem bekannten Phänomen aus, daß bei Bestrahlen einer phototropen oder photochromen Schicht mit ultraviolettem Licht der Absorptionsgrad der Schicht stark zunimmt. Demzufolge wird bei der erfindungsgemäßen Vorrichtung die in unbeleuchtetem Zustand gut durchsichtige Schicht an der Frontscheibe durch Bestrahlen mit ultravioletten Lichtbündeln, deren Querschnittsformen den verschiedenen Symbolen entsprechen, an den bestrahlten Stellen weniger durchsichtig, mit anderen Worten, die' auf die Schichijprojizierten Symbole heben sich dunkel gegen die helle Umgebung ab.The invention is based on the known phenomenon that upon irradiation of a photochromic or photochromic layer with ultraviolet light the degree of absorption of the layer increases sharply. Accordingly, in the device according to the invention the layer on the windshield, which is clearly transparent when it is not illuminated, by irradiating with ultraviolet light beams, whose cross-sectional shapes correspond to the various symbols, less transparent in the irradiated areas, with others Words, the 'on the Shichij-projected symbols stand out dark against the bright surroundings.

Da die Schicht im unbeleuchteten Zustand gut durchsichtig und im beleuchteten Zustand ebenfalls noch durchsichtig ist, kann ein Vielzahl von Meßwerten und Informationen dargestellt werden bzw. besteht die Möglichkeit, große Abbildungsmaßstäbe verwenden zu können, ohne daß eine ins Gewicht fallende Sichtbehinderung des Fahrzeugführers durch die dargestellten Informationen und Meßwerte auftritt.Since the layer is clearly transparent in the non-illuminated state and also still transparent in the illuminated state, a large number of measured values and information can be displayed or there is the possibility of large image scales to be able to use without a significant visual obstruction of the vehicle driver by the information presented and measured values occurs.
Im Hinblick auf eine minimale Beeinflussung der Sicht des Fahrzeugführers besteht die Schicht am zweckmäßigsten aus einem phototropen oder.photochromen Glas. An sich kann die Schicht auch aus Kunststoff bestehen, Jedoch haben solche Schichten im allgemeinen den Nachteil, daß ihre Lichte durchlässigkeit mit der Zeit abnimmt.With a view to minimally influencing the driver's view, the layer is most expediently composed of a photochromic or photochromic glass. In itself the Layer also consist of plastic, but have such Layers generally have the disadvantage that their light permeability decreases over time.
Des weiteren hat es sich als zweckmäßig erwiesen, die Schicht auf der Innenseite der Frontscheibe anzubringen. Es besteht dann die Möglichkeit, Lichtquellen geringerer Leistung verwenden zu können. Durch den Einsatz solcher Lichtquellen ist darüber hinaus sicher gestellt, daß der Fahrzeugführer keiner oder nur einer äußerst geringen UV-Bestrahlung ausgesetzt ist.Furthermore, it has proven to be useful to apply the layer on the inside of the front pane. It then exists the possibility of using lower power light sources. By using such light sources is about it In addition, it is ensured that the driver of the vehicle is exposed to no or only extremely low UV radiation.
Um schließlich den Kontrast zwischen projizierter Information und der Umgebungshelligkeit den jeweiligen Wünschen des Fahrzeugführers anpassen zu können, empfiehlt es sich, Mittel zum Verändern der Emissions±ärke der Lichtquelle vorzusehen. Diese Mittel können im Strahlengang angeordnete Filter oder ein im Betriebsstromkreis der Lichtquelle befindlicher Regler sein.Finally, the contrast between projected information and to be able to adapt the ambient brightness to the respective wishes of the vehicle driver, it is advisable to use means for Change the emissivity of the light source. These Means can be filters arranged in the beam path or a regulator located in the operating circuit of the light source.
Die Erfindung sei anhand der Zeichnung, die in zum Teil schematischer Darstellung ein Ausführungsbeispiel enthält, näher erläutert.The invention is based on the drawing, which is in part schematic Representation contains an embodiment, explained in more detail.

Die Vorrichtung, die zum Anzeigen der Motortemperatur eines Kraftfahrzeugs dient, umfaßt eine Projektionseinrichtung 1 und einen an der Innenseite der Frontscheibe 2 im Gesichtsfeld des Fahrzeugführers befindlichen Schirm 3. The device, which is used to display the engine temperature of a motor vehicle, comprises a projection device 1 and a screen 3 located on the inside of the windshield 2 in the field of vision of the vehicle driver.
Die Projektionseinrichtung 1 enthält eine ultraviolette Strahlen emittierende Lichtquelle 4, ein bekanntes Linsensystem 5 und eine dazwischen angeordnete lichtdurchlässige dünne Scheibe 6, auf die eine lichtundurchlässige Folie 7 mit den ausgestanzten Symbolen - im vorliegenden Fall Zahlen aufgebracht ist. Die Scheibe 6 ist drehbar gelagert und wird in Abhängigkeit von der Jeweiligen Motortemperatur um einen bestimmten Winkel aus ihrer Ruhelage gedreht.The projection device 1 contains a light source 4 emitting ultraviolet rays, a known lens system 5 and a light-permeable thin disc 6 arranged in between, on which an opaque film 7 with the punched out symbols - in the present case numbers is applied. The disc 6 is rotatably mounted and is rotated by a certain angle from its rest position depending on the respective engine temperature.
Der Schirm 3 besteht aus einer phototropen Glasplatte 8, die durch Kitten oder Kleben an der Frontscheibe 2 befestigt ist. Die durch die ausgestanzten Teile der lichtundurchlässigen Folie 7 und das Linsensystem 5 auf die phototrope Glasplatte treffenden ultravioletten Strahlen bewirken eine örtliche Erhöhung des Absorptionsgrades in der Glasplatte 8, so daß die einzelnen Zahlen sich dunkel gegen die helle Umgebung abheben. Zur Einstellung des gewünschten Kontrastes ist die Lichtquelle 4 über einen Spannungsregler 9 an die Betriebsspannungsquelle 10 angeschlossen.The screen 3 consists of a photochromic glass plate 8 which is attached to the front pane 2 by cementing or gluing. The ultraviolet rays striking the photochromic glass plate through the punched-out parts of the opaque film 7 and the lens system 5 cause a local increase in the degree of absorption in the glass plate 8, so that the individual numbers stand out dark against the bright surroundings. To set the desired contrast, the light source 4 is connected to the operating voltage source 10 via a voltage regulator 9.
