Description

Die vorliegende Erfindung betrifft eine Signalvorrichtung mit einer Signalplatte für die Anbringung von Glühlampenmodulen, wobei die Signalplatte Durchbrüche sowie Befestigungs- und/oder Positionierungselemente für die Anordnung der Glühlampenmodulen aufweist.The present invention relates to a signaling device with a signal plate for the attachment of incandescent lamp modules, wherein the signal plate has openings as well as fastening and / or positioning elements for the arrangement of the incandescent lamp modules.

Nach wie vor kommt Lichtsignalen für die Steuerung von Verkehrsflüssen, insbesondere zur Steuerung des schienengebundenen Verkehrs, eine überragende Bedeutung zu, auch wenn beispielsweise in der Eisenbahntechnik mittlerweile Normen bestehen, die eine Zugbeeinflussung ausschliesslich aufgrund von per Funk in den Führerstand einer Lokomotive oder eines Steuerwagens übertragenen Informationen vorsehen (ETCS Level 2 und höher). Derartige Lichtsignale sind derzeit noch zu einem weit überwiegenden Teil mit herkömmlichen Glühlampen ausgestattet. Die begrenzte Lebensdauer derartiger Leuchtmittel stellt jedoch ein sehr grosses Risiko für die Sicherheit des Verkehrs dar, weil nicht-leuchtende Signalpunkte den eigentlich anzuzeigenden Signalbegriff gefährlich verfälschen können. Aus diesem Grund stehen für die stellwerkseitige Überwachung der Funktion der Glühlampen vor allen Dingen solche Massnahmen bereit, die aus dem üblicherweise von einer Glühlampe aufgenommenen Lampenstrom auf die ordnungsgemässe Funktion derselben schliessen lassen. Naturgemäss besteht bei dieser Überwachungsart jedoch ein erhebliches Potential für Fehlfolgerungen, weil es beispielsweise aufgrund parasitärer Leckströme aufgrund der zum Teil sehr langen Kabelstrecken zu Stromflüssen kommt, die mit dem Leuchten der eigentlichen Signallampe überhaupt nichts zu tun haben. Ebenso kann eine erhebliche (Personen-) Gefährdung typischerweise auch durch den Vorgang des Lampenwechsels resultieren, weil hier oft bei Dunkelheit, schlechten Witterungsbedingungen und mitunter auch unter erheblichem Zeitdruck gearbeitet werden muss.As before, light signals for the control of traffic flows, in particular for the control of rail-bound traffic, are of paramount importance, even if, for example, standards now exist in railway engineering which transmit a train control exclusively by radio transmission into the cab of a locomotive or a control car Provide information (ETCS Level 2 and above). Such light signals are currently still equipped to a large extent with conventional light bulbs. However, the limited life of such bulbs represents a very high risk to the safety of traffic, because non-luminous signal points can distort the actually signal to be displayed dangerous. For this reason, stand for the control of the function of the incandescent bulbs above all things such measures that can close from the usually recorded by a light bulb lamp current to the proper function of the same. By nature, however, there is a considerable potential for failure in this type of monitoring because, for example due to parasitic leakage currents due to the sometimes very long cable routes to current flows that have nothing to do with the illumination of the actual signal lamp. Similarly, a significant (personal) risk typically also result from the process of lamp replacement, because here often in the dark, poor weather conditions and sometimes under considerable time pressure must be worked.

Aufgrund der deutlich längeren Lebensdauer von LED-Leuchtmitteln wird daher zunehmend bei einer Ausrüstung/Nachrüstung von neuen bzw. bestehenden Signalanlagen dazu übergegangen, LED-Leuchtmittel einzusetzen. Diese LED-Leuchtmittel verfügen über eine grössere Anzahl von in einem Array angeordneten Einzel-LEDs, die zur Anzeige eines Signalbegriffs kollektiv zum Leuchten gebracht werden. Der Ausfall einer Einzel-LED oder einer geringen Anzahl von Einzel-LEDs kann aufgrund der grossen Anzahl von Lichtpunkte kaum ins Gewicht fallen, weshalb neben der gegenüber Glühlampen erhöhten Lebensdauer der LED auch die Systemfehlerrate deutlich geringer ist.Due to the significantly longer life of LED bulbs is therefore increasingly gone in equipment / retrofit of new or existing signal systems to use LED bulbs. These LED bulbs have a greater number of individual LEDs arranged in an array, which are collectively lit to indicate a signal concept. The failure of a single LED or a small number of individual LEDs can hardly fall due to the large number of points of light weight, which is why in addition to the incandescent lamps increased life of the LED and the system error rate is significantly lower.

Problematisch ist jedoch hinsichtlich einer Nachrüstung von bestehenden Signalen, dass die neuen LED-Leuchtmittel mit den Glühlampen nicht kompatibel sind und daher in der Regel hohe Kosten für die Erstellung neuer Signale anfallen und der bestehende Signalaufbau zumindest teilweise zu verschrotten ist.However, the problem with retrofitting existing signals is that the new LED bulbs are not compatible with the incandescent bulbs and therefore usually incur high costs for the creation of new signals and at least partially scrap the existing signal structure.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine Signalvorrichtung anzugeben, mit der der Ersatz von Glühlampen durch LED-Leuchtmittel in einfacher und kostensparender Weise erfolgen kann.The present invention is therefore an object of the invention to provide a signaling device with which the replacement of incandescent lamps by LED bulbs can be done in a simple and cost-saving manner.

Diese Aufgabe wird erfindungsgemäss durch eine Signalvorrichtung der eingangs genannten Art gelöst, bei der ein an die Durchbrüche sowie die Befestigungs- und/oder Positionierelemente angepasstes Trägerelement vorgesehen ist, auf welchem ein LED-Leuchtmittel angeordnet ist.This object is achieved according to the invention by a signaling device of the type mentioned, in which a to the openings and the fastening and / or positioning elements adapted support member is provided, on which an LED light source is arranged.

Auf diese Weise kann das Trägerelement, das beispielsweise als Trägerplatte oder als Trägergehäuse ausgestaltet sein kann, sozusagen als Adapter für den Einbau der LED-Leuchtmittel dienen, die in die ursprünglich zur Anbringung und Befestigung von Glühlampenmodulen vorgesehenen Elemente eingesetzt werden kann. Damit muss beim Austauschvorgang nur das Glühlampenmodul als solches entfernt werden, und das Trägerelement, bestückt mit dem LED-Leuchtmittel, kann eingesetzt werden.In this way, the support element, which may be configured, for example, as a support plate or as a carrier housing, so to speak serve as an adapter for the installation of the LED bulbs, which can be used in the originally provided for mounting and mounting of incandescent modules elements. This only has to be done during the replacement process the incandescent module can be removed as such, and the carrier element equipped with the LED illuminant can be used.

Um mit dem LED-Leuchtmittel eine dem Glühlampenmodul vergleichbare Abstrahlcharakteristik erzeugen zu können, kann das Trägerelement in einer vorteilhaften Weiterbildung der Erfindung einen an das LED-Leuchtmittel angepassten Glas- und/oder Kunststoffkörper umfassen, der im Lichtweg angeordnet ist. Dieser Glas- und/oder Kunststoffkörper kann dabei gemäss den Anforderungen die entsprechenden Eigenschaften aufweisen, also beispielsweise als Streu- oder Sammellinse dienen.In order to be able to generate a radiation characteristic comparable to the incandescent lamp module with the LED illuminant, in an advantageous development of the invention, the carrier element can comprise a glass and / or plastic body adapted to the LED illuminant, which is arranged in the light path. This glass and / or plastic body can according to the requirements have the appropriate properties, so for example serve as a scattering or converging lens.

Damit auch die stellwerkseitige und/oder linienseitige Steuerung und Speisung des LED-Leuchtmittels in für das Glühlampenmodul gewohnter Weise erfolgen kann, kann eine elektrische Anschlussgruppe des LED-Leuchtmittels mit einer Anschlussgruppe eines Glühlampenmoduls kompatibel ausgestaltet werden. Dabei kann diese elektrische Anschlussgruppe mit entsprechenden elektrischen Bauteilen bestückt sein, um die elektrischen Eigenschaften des Glühlampenmoduls nachzuahmen. So können beispielsweise Mittel vorgesehen sein, die den Stromverbrauch im LED-Leuchtmittelkreis an den Stromverbrauch eines Glühlampenmoduls anpassen.So that the control unit side and / or line-side control and power supply of the LED light source can be done in the usual manner for the incandescent lamp module, an electrical terminal group of the LED light source can be made compatible with a terminal group of a light bulb module. In this case, this electrical connection group may be equipped with corresponding electrical components in order to simulate the electrical properties of the incandescent lamp module. For example, means may be provided which adjust the power consumption in the LED lighting circuit to the power consumption of a light bulb module.

Die Erfindung wird nachfolgend anhand der Zeichnung beispielsweise näher erläutert. Dabei zeigen:

Figur 1
eine perspektivische Rückansicht auf eine mit einem LED-Leuchtmittel bestückte Signalplatte; und
Figur 2
eine perspektivische Vorderansicht auf die mit dem LED-Leuchtmittel bestückte Signalplatte gemäss Figur 1.
The invention will be explained in more detail with reference to the drawing, for example. Showing:
FIG. 1
a rear perspective view of a equipped with an LED illuminant signal plate; and
FIG. 2
a perspective front view of the equipped with the LED illuminant signal plate according to Figure 1.

Figur 1 zeigt eine perspektivische Rückansicht auf ein Signal 2, welches eine einem hier nicht weiter dargestellten Betrachter zugewandte Signaltafel 4 und eine rückwärtige Signalplatte 6 aufweist. Das Signal 2 ist ursprünglich mit hier nicht weiter dargestellten Glühlampenmodulen ausgerüstet gewesen. Zur Anordnung und Befestigung dieser Glühlampenmodule weist die Signalplatte 6 mehrere Durchbrüche 8, 8a sowie Befestigungselemente 10 und Positionierelemente 12 auf. Im oberen Durchbruch 8a ist im vorliegenden Ausführungsbeispiel eine Trägerplatte 14 eingesetzt, auf welcher ein LED-Leuchtmittel 16 angeordnet ist. In der gezeigten Darstellung sind von dem LED-Leuchtmittel 16 ein Leuchtengehäuse 18, ein rückwärtiger Kühlkörper 20 sowie eine gekapselte elektrische Anschlussgruppe 22 erkennbar. Dank der an die Durchbrüche 8, 8a sowie die Befestigungselemente 10 und Positionierelemente 12 angepassten Trägerplatte 14 kann das LED-Leuchtmittel 16 in das Signal 2 integriert werden, ohne dass an dem Signal 2 weitere Umbauten vorgenommen werden müssen.FIG. 1 shows a perspective rear view of a signal 2 which has a signal panel 4 facing a viewer, not shown here, and a rear signal panel 6. The signal 2 was originally equipped with incandescent lamp modules not shown here. For arranging and mounting these incandescent modules, the signal plate 6 has a plurality of openings 8, 8a and fastening elements 10 and positioning elements 12. In the upper opening 8a a support plate 14 is used in the present embodiment, on which an LED lighting means 16 is arranged. In the illustration shown, a luminaire housing 18, a rearward heat sink 20 and an encapsulated electrical connection group 22 can be recognized by the LED illuminant 16. Thanks to the carrier plate 14 adapted to the apertures 8, 8a and the fastening elements 10 and positioning elements 12, the LED illuminant 16 can be integrated into the signal 2, without having to make any further modifications to the signal 2.

Auch hinsichtlich der stellwerkseitigen und/oder linienseitigen Steuerung und/oder Überwachung ist es mit einer entsprechend angepassten elektrischen Anschlussgruppe 22 möglich, das bisher für das Glühlampenmodul verwendete Steuer- und/oder Überwachungsregime exakt beizubehalten. So wird beispielsweise durch eine Parallelschaltung eines elektrischen Widerstandes in der elektrischen Anschlussgruppe 22 ein erhöhter Stromverbrauch des LED-Leuchtmittels 16 künstlich herbeigeführt, der bei leuchtendem LED-Leuchtmittel weitgehend dem Stromverbrauch eines herkömmlichen Glühlampenmoduls entspricht.Also with regard to the control unit and / or line-side control and / or monitoring, it is possible with a correspondingly adapted electrical connection group 22 to maintain exactly the control and / or monitoring regime previously used for the incandescent lamp module. Thus, for example, an increased power consumption of the LED lighting means 16 is artificially caused by a parallel connection of an electrical resistance in the electrical connection group 22, which largely corresponds to the power consumption of a conventional incandescent lamp module when the LED illuminant.

Figur 2 zeigt nun in perspektivischer Ansicht die Vorderseite des Signals 2 mit seiner Signaltafel 4. In den oberen Durchbruch 8a ist das LED-Leuchtmittel 16 eingesetzt, von dem in dieser Darstellung nur eine die LEDs schützende Glasplatte 24 zu erkennen ist. Ein die seitliche Abstrahlung des Signallichts einengender Hüllkörper 26 ist schon Bestandteil des Signals 2 gewesen, als dieses noch mit Glühlampenmodulen ausgerüstet war. Selbstverständlich kann die Glasplatte 24 an die gewünschte Abstrahlcharakteristik des Signalpunkts angepasst werden, beispielsweise in Form einer Streu- oder Sammellinse.Figure 2 shows a perspective view of the front of the signal 2 with its signal panel 4. In the upper opening 8a, the LED bulb 16 is inserted, of which in this illustration, only a protective glass plate the LEDs 24 can be seen. An enveloping body 26 narrowing the lateral emission of the signal light has already been part of the signal 2 when it was still equipped with incandescent lamp modules. Of course, the glass plate 24 can be adapted to the desired radiation characteristic of the signal point, for example in the form of a scattering or condenser lens.
