Description

Die Erfindung bezieht sich auf eine verkehrstechnische Signalisierungseinrichtung für selbstleuchtende Anzeigen gemaß dem Oberbegriff des Patentanspruches 1.The invention relates to a traffic signaling device for self-illuminating displays according to the Preamble of claim 1.

Für verkehrstechnische Signalisierungseinrichtungen mit selbstleuchtenden Anzeigen, wie Lichtsignalanlagen an Kreuzungspunkten oder Wechselverkehrszeichen werden heutzutage Glühlampen oder Halogenlampen verwendet.For traffic signaling devices with self-illuminating displays, such as traffic lights at intersections or variable message signs are nowadays Incandescent or halogen lamps are used.

Aus EP 0 467 034 ist beispielsweise eine Anzeigevorrichtung für ein Wechselverkehrszeichen bekannt, bei dem beliebige Anzeigen, die aus mindestens einem nicht veränderbaren Anzeigenteil und einem beliebig wählbaren Anzeigenteil zusammensetzbar sind, dargestellt werden. Dabei sind für jeden nicht veränderbaren Anzeigenteil getrennte, beleuchtbare Bündel von Lichtleitfasern vorgesehen, deren freie Enden entsprechend dem zugeordneten, nicht veränderbaren Anzeigenteil verteilt in einer Anzeigetafel angeordnet sind. Der beliebig wählbare Anzeigenteil ist mittels eines prozessorgesteuerten Matrixfeldes von Anzeigenelementen darstellbar, wobei jedes Anzeigeelement durch eine beleuchtete Lichtleitfaser ausgeführt ist. Die beleuchteten Lichtleitfasern werden dabei durch Halogenlampen beleuchtet. Nachteilig bei diesem Verfahren ist zum einen die geringe Lebensdauer von Halogenlampen und zum anderen deren hoher Energieverbrauch.From EP 0 467 034 there is, for example, a display device known for a variable message sign in which any advertisement, those from at least one non-changeable part of the ad and any display part that can be selected are shown. There are not for everyone changeable display part separate, illuminable bundle of Optical fibers are provided, the free ends accordingly distributed to the assigned, unchangeable part of the ad are arranged in a display board. The freely selectable The display part is by means of a processor-controlled matrix field display elements, each display element carried out by an illuminated optical fiber is. The illuminated optical fibers are replaced by halogen lamps illuminated. This method is disadvantageous on the one hand the short lifespan of halogen lamps and on the other others their high energy consumption.

Daher sind vereinzelt auch bereits Leuchtdioden für den Einsatz in verkehrstechnischen Signalisierungseinrichtungen vorgesehen.For this reason, light-emitting diodes are already used occasionally provided in traffic signaling devices.

Aus EP 0 694 894 ist eine Signalleuchte bekannt, die zumindest teilweise mit Leuchtdioden versehen ist, die innerhalb der Signalleuchte von einer ersten zu zumindest einer zweiten Abstrahlrichtung abkippbar gelagert sind und durch Verstellscheiben gruppenweise positioniert werden können. Die vorgesehene Haltevorrichtung ist allerdings recht kompliziert und nicht für eine einfache Montage geeignet.A signal lamp is known from EP 0 694 894, at least is partially provided with LEDs that inside the signal lamp from a first to at least a second Beam direction are tiltable and stored by adjusting discs can be positioned in groups. The intended Holding device is, however, quite complicated and not suitable for easy assembly.

Es ist daher Aufgabe der Erfindung, eine verkehrstechnische Signalisierungseinrichtung anzugeben, die gegenüber den bekannten Signalisierungseinrichtungen einen robusteren Aufbau und eine längere Lebensdauer aufweist.It is therefore an object of the invention to provide a traffic engineering To indicate signaling device that compared to the known Signaling devices a more robust structure and has a longer lifespan.

Eine bevorzugte Ausgestaltung ergibt sich nach Patentanspruch 3 durch eine Verzahnung an der Haltevorrichtung, die ebenfalls eine besonders einfache Montage der Haltevorrichtung gewährleistet.A preferred embodiment results from claim 3 by a toothing on the holding device, which also a particularly simple assembly of the holding device guaranteed.

Eine weitere Verbesserung der Wärmeleitfähigkeit der Haltevorrichtung wird dadurch erzielt, daß nach Patentanspruch 4 die Leuchtdiode durch eine aushärtbare Wärmeleitpaste in der Haltevorrichtung befestigt ist. A further improvement in the thermal conductivity of the holding device is achieved in that according to claim 4 the LED through a curable thermal paste in the Holding device is attached.

Nach Patentanspruch 5 ergibt sich eine Verbesserung der optischen Abstrahlungseigenschaften durch eine optische Abbildungseinrichtung, die in der frontseitigen Öffnung der Haltevorrichtung vorgesehen ist.According to claim 5 there is an improvement in the optical Radiation properties through an optical imaging device, in the front opening of the holding device is provided.

Eine besonders preiswerte Ausgestaltung ergibt sich durch eine optische Abbildungseinrichtung aus einem transparenten Kunststoff wie beispielsweise Polymethacrylat (PMMA, Handelsname Plexiglas) oder Polycarbonat (PC, Handelsname Makrolon) nach Patentanspruch 6.A particularly inexpensive embodiment results from a optical imaging device from a transparent Plastic such as polymethacrylate (PMMA, trade name Plexiglas) or polycarbonate (PC, trade name Makrolon) according to claim 6.

Dadurch wird der Verdrahtungsaufwand reduziert.This results in the preferred also according to claim 8 Embodiment in which only one connection of the LED directly is contacted, and the other connection (for example the ground connection) electrically conductive with the Holding device connected, the holding device electrically conductively connected to the front panel and the front panel is connected to the control unit via a cable connection. This reduces the wiring effort.
