The display has a display surface with a matrix of self-illuminating image points (3) for the representation of symbols and images and a sunlight screen (2) protruding in front of the image points. The screen arrangement has separate screening elements individually associated with the image points and that can be mechanically positioned on the display surface independently of each other.

Description

Die Erfindung bezieht sich auf eine Leuchtanzeigevorrichtung für den Straßenverkehr mit einer Anzeigefläche, die zum Darstellen von Symbolen oder Bildern selbstleuchtende, gerastert angeordnete Bildpunkte und eine diese nach vorn überragende Abschirmvorrichtung für Sonnenlicht aufweist.The invention relates to a light display device for road traffic with a display surface, which is used to display symbols or images self-luminous, screened pixels and one to the front has outstanding shielding device for sunlight.

Bei einer Leuchtanzeigevorrichtung, wie sie beispielsweise in der DE 40 40 567 C1 angegeben ist, sind auf einer Anzeigefläche Bildpunkte zur Darstellung unterschiedlicher Symbole gerastert in Zeilen und Spalten angeordnet. Zum Abschirmen der Bildpunkte werden bei einer derartigen Leuchtanzeigevorrichtung zum Beispiel nach vorne vorstehende kassettenförmige Aufnahmen gebildet, indem zwischen den Bildpunkten horizontale und vertikale Leisten gitterförmig angebracht werden. Um eine genügende Abschirmung des Sonnenlichts zu erhalten, müssen die Aufnahmen genügend tief sein, wobei die Tiefe aber dadurch eingeschränkt ist, daß die Bildpunkte unter einem bestimmten Beobachtungswinkel schräg von unten sichtbar sein müssen. Zudem kann durch die vertikalen Leisten der seitliche Beobachtungswinkel eingeschränkt sein, wodurch die Erkennbarkeit der Anzeige eingeschränkt sein kann. Auch sind die Bildpunkte an eine vertikale und horizontale Ausrichtung sowie an einen bestimmten Abstand entsprechend dem gitterförmigen Vorsatz gebunden.In the case of a luminous display device such as that described in DE 40 40 567 C1 is specified, there are pixels on a display surface for displaying different ones Symbols arranged in rows and columns. To shield the pixels are in such a light display device for example, projecting cassette-shaped receptacles formed by horizontal and vertical bars are placed in a grid between the pixels become. In order to obtain sufficient shielding from sunlight, the recordings must be sufficiently deep, but the depth thereby is limited that the pixels at a certain observation angle must be visible diagonally from below. In addition, the vertical Last the lateral viewing angle may be restricted, making it more noticeable the display may be restricted. The pixels are also on vertical and horizontal alignment and at a certain distance bound according to the lattice-shaped intent.

Der Erfindung liegt die Aufgabe zugrunde, eine Leuchtanzeigevorrichtung der eingangs genannten Art bereitzustellen, bei der bei verbesserter Abschirmung des Sonnenlichts eine bessere Erkennbarkeit der Anzeige erreicht wird, wobei die Anordnung der Bildpunkte weitgehend frei wählbar ist.The invention has for its object a lighting display device Provide the type mentioned in the case of improved shielding sunlight better visibility of the display is achieved the arrangement of the pixels is largely freely selectable.

Diese Aufgabe wird mit den Merkmalen des Anspruchs 1 gelöst. Hiernach ist vorgesehen, daß die Abschirmvorrichtung separate, den Bildpunkten individuell zugeordnete Abschirmelemente aufweist, die mechanisch unabhängig voneinander auf der Anzeigefläche positionierbar sind. Durch die Gestaltung der Abschirmvorrichtung mit den separaten Abschirmelementen können diese entsprechend den Bildpunkten angeordnet und hinsichtlich einer jeweiligen optimalen Lichtabschirmung unter Beachtung der erforderlichen Beobachtungsbedingungen ausgelegt und angeordnet werden. Beispielsweise können auf einer derartigen Anzeigefläche beliebige Piktogramme dargestellt werden, ohne daß eine Anordnung der Bildpunkte in vertikaler und horizontaler Ausrichtung eingehalten werden muß.This object is achieved with the features of claim 1. After that is provided that the shielding device separately, the pixels individually has assigned shielding elements that are mechanically independent of one another can be positioned on the display surface. By designing the shielding device with the separate shielding elements, these can be used accordingly the pixels arranged and with respect to a respective optimal Light shielding taking into account the necessary observation conditions laid out and arranged. For example, on such Any pictograms can be displayed without a Arrangement of the pixels in vertical and horizontal alignment observed must become.

Eine gute Abschirmung von seitlich einfallendem Sonnenlicht wird dadurch erzielt, daß die einzelnen Abschirmelemente schutenartig geformt sind, wobei vom freien vorderen Ende des Abschirmelements aus zum zugehörigen Bildpunkt hin dessen seitlichen Abschirmbereiche zunehmend herabgezogen sind, da die Abschirmelemente dabei seitlich über die Bildpunkte herabgewölbt sind. Andererseits ist die seitliche Beobachtung von vorn und unten weitgehend ungehindert gewährleistet.Good shielding from laterally incident sunlight is achieved by that the individual shielding elements are shaped like a barge, whereby from the free front end of the shielding element to the associated pixel towards the side shielding areas are increasingly pulled down, since the shielding elements are arched sideways over the pixels. On the other hand, lateral observation from the front and from below is largely unimpeded guaranteed.

Eine einfache Herstellung und Montage, bei der eine eindeutige Anordnung der Abschirmelemente bezüglich der Bildpunkte sichergestellt ist, wird dadurch erreicht, daß die Abschirmelemente an Sockeln, an denen die Bildpunkte angebracht sind, einstückig angeformt, angeklebt oder eingesteckt sind.A simple manufacture and assembly, with a clear arrangement of the Shielding elements with regard to the pixels is ensured, that the shielding elements on bases to which the pixels are attached are molded in one piece, glued or inserted.

Dabei besteht ein hinsichtlich der Fertigung und der Bestückung einfacher Aufbau darin, daß die Bildpunkte Leuchtdioden sind und daß die Sockel, in die die Leuchtdioden eingesteckt sind, auf einer Platine angebracht sind.There is a simple structure in terms of production and assembly in that the pixels are light emitting diodes and that the base into which the LEDs are inserted, are attached to a circuit board.

Eine möglichst weitgehende Abschirmung des Sonnenlichts bei möglichst geringer Einschränkung der Beobachtungsbedingungen wird dadurch unterstützt, daß der Abstand zwischen dem Umfangsrand der Bildpunkte und der Innenseite der zugehörigen Abschirmelemente weniger als 2 mm beträgt. Hierdurch können die Abschirmelemente möglichst kurz ausgebildet werden.The greatest possible shielding of sunlight with the least possible Limitation of the observation conditions is supported by the fact that the distance between the peripheral edge of the pixels and the inside of the associated shielding elements is less than 2 mm. This allows the Shielding elements are made as short as possible.

Eine geeignete Dimensionierung ergibt sich beispielsweise dadurch, daß der vertikale Abschirmwinkel gegen die Horizontale höchstens 20 Grad beträgt. Auch kleinere Abschirmwinkel von zum Beispiel 10° sind bei Gewährleistung ausreichender Beobachtungsbedingungen erzielbar.A suitable dimensioning results, for example, that the vertical Shielding angle against the horizontal is at most 20 degrees. Also Smaller shielding angles of, for example, 10 ° are more sufficient if warranted Observation conditions achievable.

Die Erfindung wird nachfolgend anhand eines Ausführungsbeispiels unter Bezugnahme auf die Zeichnungen näher erläutert. Es zeigen:

The invention is explained in more detail below using an exemplary embodiment with reference to the drawings. Show it:
Fig. 1
a light display device with light emitting diodes and a shielding device in a side view, partially cut,
Fig. 2
seen from below and
Fig. 3
a section of the light indicator from the front.

Fig. 1 zeigt eine Leuchtanzeigevorrichtung 1 mit selbstleuchtenden Bildpunkten in Form von gerastert auf einer Platine 5 angeordneten Leuchtdioden 3, über denen nach vorne in Richtung des Beobachters vorstehende schutenartige Licht-Abschirmelemente 2 für Fremdlicht, insbesondere Sonnenlicht angeordnet sind. Die Lichtabschirmelemente 2 sind an Sockeln 4 angeformt, die ihrerseits auf der Platine 5 angebracht sind und die Leuchtdioden 3 steckbar aufnehmen.1 shows a luminous display device 1 with self-luminous pixels in the form of light-emitting diodes 3 arranged on a circuit board 5, above which chute-like light shielding elements protruding towards the front of the observer 2 are arranged for extraneous light, especially sunlight. The light shielding elements 2 are molded onto bases 4, which in turn are on the Board 5 are attached and receive the LEDs 3 pluggable.

Wie auch aus den Fig. 2 und 3 ersichtlich, sind die schutenartigen Abschirmelemente 2 in geringem Abstand gegenüber dem Außenumfang der Leuchtdioden 3 in der Ansicht von vorn bogenförmig angeordnet, wobei sie im Bereich des Sockels 4 die Leuchtdioden 3 berühren können oder minimal beabstandet sind, so daß lediglich gewährleistet ist, daß die Leuchtdioden 3 ungehindert in den Sockel 4 eingesteckt werden können. Durch diese enge Anordnung der Abschirmelemente 2 bezüglich der Leuchtdioden 3 und ihre seitliche Umwölbung der Leuchtdioden 3 wird bei möglichst geringer Abschirmfläche nach vorn und nach der Seite eine optimale Abschirmung auch von flach einfallendem und seitlichem Sonnenlicht erzielt. Die Länge der Lichtabschirmelemente 2 richtet sich dabei nach einem gewünschten vertikalen Grenzwinkel α für die Abschirmung, wobei dieser zum Beispiel auf maximal 20° oder auch 10° festgelegt werden kann, wobei andererseits ein genügend großer Beobachtungswinkel von unten gewährleistet ist, da der durch die Rasterung der Leuchtdioden 3 gebildete Abstand zwischen den Abschirmelementen 2 und den jeweils darüber angeordneten Leuchtdioden 3 genügend groß ist. As can also be seen from FIGS. 2 and 3, the bar-like shielding elements are 2 at a short distance from the outer circumference of the LEDs 3 arranged in the form of an arc from the front, being in the area of the base 4 can touch the light emitting diodes 3 or be minimally spaced are, so that it is only ensured that the LEDs 3 unhindered in the base 4 can be inserted. This close arrangement of the Shielding elements 2 with respect to the light emitting diodes 3 and their lateral curvature the light emitting diodes 3 is forward with the smallest possible shielding area and to the side an optimal shielding from flat and side sunlight. The length of the light shielding elements 2 is aligned according to a desired vertical limit angle α for the shield, whereby this is fixed, for example, to a maximum of 20 ° or 10 ° can be, on the other hand a sufficiently large observation angle of is guaranteed below, since that formed by the rasterization of the light emitting diodes 3 Distance between the shielding elements 2 and above each arranged LEDs 3 is sufficiently large.

In seitlicher Richtung ergibt sich durch die schutenartige Ausbildung, bei der von dem freien Ende der Abschirmelemente 2 ausgehend diese zunehmend nach unten um die Leuchtdioden 3 gezogen sind, auch eine gute Abschirmung des Sonnenlichts außerhalb eines durch die Gestaltung der Lichtabschirmelemente 2 wählbaren horizontalen Grenzwinkels β. Dabei wird andererseits ein großer seitlicher Beobachtungswinkel gewährleistet.In the lateral direction results from the barge-like training in which starting from the free end of the shielding elements 2, these increasingly pulled down around the LEDs 3, also a good shield of sunlight outside of one by the design of the light shielding elements 2 selectable horizontal limit angles β. On the other hand, a large side viewing angle guaranteed.

Bei der Auslegung der Abschirmelemente 2 ist einerseits die Reflexion an der Außenseite der Leuchtdioden 3 zu vermeiden, insbesondere aber die Reflexion an in den Leuchtdioden 3 vorhandenen Reflektorelementen 6, die sich bei Auffall des Sonnenlichts insbesondere störend bemerkbar macht. Mit den Abschirmelementen wird ein hoher Kontrast für die sichere Erkennbarkeit der Anzeige erreicht.When designing the shielding elements 2, the reflection on the one hand To avoid the outside of the LEDs 3, but especially the reflection on the reflector elements 6 present in the light-emitting diodes 3, which change when noticeable of the sunlight is particularly noticeable. With the shielding elements becomes a high contrast for the reliable recognition of the display reached.

Durch die Anformung der Lichtabschirmelemente 2 an den Sockeln 4 ergibt sich eine einfache Herstellung und eine einfache Montage, wobei die einzelnen Bildpunkte in Form der Leuchtdioden 3 auf der Anzeigefläche frei positioniert werden können, um beispielsweise beliebige Piktogramme darzustellen.The molding of the light shielding elements 2 on the bases 4 results in simple manufacture and assembly, the individual pixels in the form of the light emitting diodes 3 can be freely positioned on the display surface can, for example, to display any pictogram.
