Die Leuchtdioden werden dabei so angesteuert, daß sie - je nach Verwendungszweck - einen Text wiedergeben oder aber auch sonstige symbolische Hinweise. Derartige Wechselverkehrszeichen finden insbesondere im Straßenbau vielfältig Verwendung.The LEDs are controlled in such a way that - depending on the intended use - they display text or other symbolic information. Such variable message signs are used in many different ways, particularly in road construction.
Die dabei vor den Leuchtdioden angeordnete Kontrastblende dient zum einen dem mechanischen Schutz der Leuchtdiode,
insbesondere aber erhöhen sie den Kontrast, indem sie die Leuchtdioden vor dem Auffallen von Fremdlicht, das sich
in den Leuchtdioden spiegeln würde, weitgehend schützen.
Dies ist insbesondere dann von Bedeutung, wenn das Wechselverkehrszeichen von der tiefstehenden Sonne angestrahlt
wird, also in einer Situation,, in der die Lesbarkeit des Wechselverkehrszeichens beeinträchtigt wird.The contrast screen arranged in front of the LEDs serves on the one hand to mechanically protect the LED, but in particular it increases the contrast by largely protecting the LEDs from the impact of extraneous light that would be reflected in the LEDs.
This is particularly important when the variable message sign is illuminated by the low sun, i.e. in a situation in which the legibility of the variable message sign is impaired.
Der Erfindung liegt die Aufgabe zugrunde, ein Wechselverkehrszeichen der eingangs genannten Art zu schaffen, bei der die Lesbarkeit bei auf das Wechselverkehrszeichen strahlender, relativ tiefstehender Sonne gewährleistet ist.The invention is based on the object of creating a variable message sign of the type mentioned at the beginning, in which legibility is guaranteed when the sun shines on the variable message sign at a relatively low position.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß die Löcher in der Kontrastblende unrund ausgebildet sind und deren lichte Weite in der Horizontalen größer als in der Vertikalen ist.According to the invention, this object is achieved in that the holes in the contrast panel are non-circular and their clear width is larger in the horizontal than in the vertical.
Die Löcher sind dabei bei einem bevorzugten Ausführungsbeispiel kreissegmentförmig, aber größer als halbkreisförmig ausgebildet, wobei die das am Kreis fehlende Kreissegment der Löcher begrenzende Sehne horizontal verläuft. In a preferred embodiment, the holes are circular segment-shaped, but larger than semicircular, wherein the chord that delimits the circular segment of the holes that is missing from the circle runs horizontally.
Die Löcher können jedoch auch beispielsweise rechteckig, sichelförmig oder oval ausgebildet sein.However, the holes can also be rectangular, crescent-shaped or oval, for example.
Die Erfindung wird im folgenden anhand einer Zeichnung erläutert. Dabei zeigt:The invention is explained below using a drawing. It shows:
Fig. 1 eine Draufsicht auf einen Ausschnitt auf die Kontrastiblende 14, undFig. 1 is a plan view of a detail of the contrast aperture 14, and
Fig. 2 eine Seitenansicht auf den in Fig. 1 gezeigten Ausschnitt.Fig. 2 is a side view of the section shown in Fig. 1.
Das Wechselverkehrszeichen besteht aus einer Trägerplatte 10, die eine Vielzahl von in einer Matrix angeordneten, einzeln elektrisch ansteuerbaren Leuchtdioden 12 trägt. Vor der Trägerplatte 10 ist eine Kontrastblende 14 angeordnet, die mit einer Vielzahl von in einer entsprechenden Matrix angeordneten, mit den Leuchtdioden ausgerichteten Löchern 16 versehen ist. Die Löcher 16 sind kreissegmentförmig aber größer als halbkreisförmig, die das am Kreis fehlende Kreissegment begrenzende Sehne 18 verläuft horizontal. Die Kontrastblende 14 ist dabei so zu der Trägerplatte ausgerichtet, daß die Achse der Leuchtdioden 12 mit dem - gedachten - Mittelpunkt der Löcher 16 übereinstimmt.The variable message sign consists of a carrier plate 10, which carries a large number of individually electrically controllable LEDs 12 arranged in a matrix. In front of the carrier plate 10 there is a contrast panel 14, which is provided with a large number of holes 16 arranged in a corresponding matrix and aligned with the LEDs. The holes 16 are circular segment-shaped but larger than semicircular, and the chord 18 delimiting the circular segment missing from the circle runs horizontally. The contrast panel 14 is aligned with the carrier plate in such a way that the axis of the LEDs 12 coincides with the - imaginary - center of the holes 16.
Fig. 2 zeigt, daß schräg von vorne (in der Zeichnung also von rechts oben) auf die Kontrastblende 14 auffallendes Sonnenlicht die Leuchtdioden 12 nicht erreichen kann, weil sie von dem am Kreis fehlenden Kreissegment der Löcher 16 abgehalten wird.Fig. 2 shows that sunlight striking the contrast panel 14 obliquely from the front (in the drawing, from the top right) cannot reach the light-emitting diodes 12 because it is blocked by the circular segment of the holes 16 that is missing from the circle.
Es versteht sich, daß auch andere geometrische Formen der Löcher denkbar sind; von Bedeutung ist jedoch, daß die Löcher 16 in der Breite größer sind als in der Höhe, damit die das von den Leuchtdioden 12 austretende Nutzlicht nicht unnötig eingeschränkt wird.It goes without saying that other geometric shapes of the holes are also conceivable; however, it is important that the holes 16 are larger in width than in height so that the useful light emitted by the light-emitting diodes 12 is not unnecessarily restricted.
