Definitions
- the invention relates to a signaling device for command and / or signaling devices.
- Signaling devices in particular have a plurality of lighting modules which are stacked along a main axis of the signaling device.
- a light source is arranged to generate light which can be radiated out of the light module in a signaling direction to the outside to allow a corresponding signal display.
- Such a signaling device according to the prior art is, for example, in FIG. 1 shown.
- Such signaling devices have the disadvantage that they are relatively expensive to manufacture, because in each of the lighting modules, a light source with appropriate electrical or electronics and electrical leads must be established.
- a light source with appropriate electrical or electronics and electrical leads must be established.
- multi-color devices in which a plurality of light colors are displayed, thus resulting in a variety of combinations of different manufactured lighting modules with corresponding light sources.
- a construction of such signaling devices against the background of the so-called replacement light function in the event of failure of a light source is expensive and expensive.
- the lines above low voltages (5 V, 12 V) lead, for example, mains voltage of 110 V or 230 V, care must be taken in the transmission of the electrical signals from the base unit to the individual, stacked lighting modules on a shock-proof isolation , For example, allowed if a module is removed, no voltage-carrying parts allow contact.
- a signaling device has a base unit comprising at least two light sources for respectively generating light, which are arranged at a distance from each other on the base unit. Furthermore, the signaling device has at least two lighting modules, which are stacked along a main axis of the signaling device and in operative connection with the light sources, so that light generated by the light sources is coupled in a beam direction parallel to the main axis in the lighting modules. Furthermore, the lighting modules each have a reflection region for at least partial reflection of the light coupled into the lighting modules in a signaling direction, see WO2012 / 132882 . EP1677045 and EP2713100 ,
- Such signaling devices have the advantage over other solutions from the prior art that the light sources no longer have to be individually installed in the respective lighting modules, wherein light sources are laid with their electrics or electronics in a base unit.
- optical light guides for example optical waveguides
- the light is conducted to a corresponding emission position and emitted there by means of corresponding reflection regions in a signaling direction to the outside.
- a signaling device of the type mentioned in that a respective reflection region of a light module in the circumferential direction of the corresponding light module perpendicular to the main axis of the signaling device occupies only a portion of the light module, which is smaller than the total circumference of the light module and that a reflection region of a light module relative is arranged offset to a reflection region of another light-emitting module by a predetermined angle perpendicular to the main axis, wherein the reflection regions have the same radial distance from the main axis.
- light which is incident on the light module parallel to the main axis is forwarded in the direction of the main axis, for example to a further, subsequent light module.
- This can be provided in particular in areas which are arranged at the same radial distance and at a predetermined angle, so that the light in the adjoining lighting module (s) meets the reflection area located there.
- the forwarding of the light in the lighting modules can be done for example by drilling parallel to the main axis.
- the walls of the holes in this case have reflective properties, as can be done for example by polishing the surface of the material of the lighting modules or by a reflective coating.
- the holes may also contain light guides made of light-guiding material, such as a transparent plastic or glass, which has a different refractive index of the material of the lighting modules, so that it comes to the surface to the material of the lighting modules for reflection.
- Such a signaling device has several advantages over the prior art solutions.
- An advantage, as already explained, is that the electrics or electronics for generating light in the lighting modules themselves is no longer necessary. Rather, the light generation is moved by means of light sources in a base unit, so that light is generated at a central location and directed by the light modules and reflection areas to a respective emission position in a light module. In this way, a simple structure with regard to the light sources and their electrical connection.
- the saved space can be used to accommodate a large number of holes or light guides parallel to the main axis. While today's signal towers usually contain up to 5 lighting modules, a larger number is conceivable in this way, for example, 8, 12 or even 24 modules. In addition, the height can be reduced. Today's lighting modules have a height of 60 - 70 mm. The height can be reduced to 20 mm, for example, since no electrical components must be installed in the light module. The thus achievable tighter arrangement of the individual signaling areas allows a housing of more signaling at comparable height and thus new signaling, such as a running light in the signaling area or within a portion of the signaling area.
- the reflection regions of the lighting modules are due to the stacked arrangement of the lighting modules in each case in a separate plane perpendicular to the main axis.
- An encoding of the lighting modules with predetermined light sources results purely by an angular offset of the reflection regions of the lighting modules by a predetermined angle perpendicular to the main axis of the signaling device, wherein the reflection regions have the same radial distance from the main axis.
- the term "at a predetermined angle perpendicular to the main axis" in this context means an offset of the reflection ranges by an angle in a rotational direction about the major axis as a rotation axis.
- the lighting modules are designed rotationally symmetrical. Alternatively, however, other forms and shapes are conceivable.
- the illustrated signaling device obviates a cumbersome design of the light guides of the various light sources with respect to corresponding reflection areas at different positions of the signaling device.
- a disability or impairment of the light guides with each other can be avoided in this way.
- Particularly advantageous is a corresponding signaling device designed in so-called multi-color devices in which light sources and light information of different colors are used, for example in traffic signal systems of the type described.
- the signaling device described has a significantly simplified construction and a simplified and inexpensive construction compared to solutions of State of the art.
- reflection regions of the corresponding lighting modules have the same radial distance from the main axis. It is conceivable to provide, in an alternative embodiment, a further group of additional reflection regions in addition to the group of the explained reflection regions, so that in a light-emitting module at least two reflection areas are arranged.
- the respective radial distances of the first group of reflection areas and the second group of reflection areas with respect to the main axis may be the same, but also different. Within a group of reflection areas, however, the radial distance to the main axis is the same.
- Corresponding groups of reflection regions can be arranged, for example, "annularly" starting from the main axis at a different radial distance from the main axis.
- Such embodiments may be advantageous in the arrangement of the individual light sources on the base unit of the signaling device and allow some flexibility in the design.
- a Designlichtfunkton Rund be set up in this way, in which the light of several light areas (for example, two light areas) is coupled in a light module.
- the light of at least one further luminous element in the luminous module is coupled out, so that the signaling function is also provided in this case. In this way, the reliability of the signal tower can be increased.
- using multiple reflective areas in the module may allow for additional applications.
- differently colored light can be coupled in via different reflection regions, so that mixed colors are possible.
- the brightness or intensity of the individual light colors can be controlled and thus change the mixed color. In this way, other lighting effects can be achieved, such as a multi-colored flashing.
- the reflection regions of the lighting modules are arranged in a direction parallel to the main axis in each case in coincidence with at least one of the light sources in order to reflect emitted light of the corresponding light source.
- a simple assignment of a corresponding reflection range in a light module results in a or a plurality of light sources, which are arranged on the base unit locally remote from the respective light module.
- an arrangement of the light sources on the base unit coincides with a rotationally offset arrangement of the reflection areas in the individual lighting modules.
- the light generated by a light source is transported by the individual lighting modules substantially along a direction parallel to the main axis of the device.
- the reflection and emission of the coupled-in light then takes place to the outside in a signaling direction.
- the light information of a first light source for example in a beam direction parallel to the main axis, are transported to a first reflection region of a first light module, wherein the light information of a second light source, which is arranged offset from the first light source in a beam direction parallel to the main axis to a second reflection region of a second light-emitting module is transported.
- a construction supports a simple structure of a signaling device and yet allows a desired functionality of distinguishing different light information at different emission positions on the signaling device.
- all reflection regions of the lighting modules are identical. This further simplifies the construction of the lighting modules. Light information of the different light sources are uniformly conducted in the device and reflected outwardly in a signaling direction. In this case, a uniform construction of the reflection regions can be provided for nevertheless differently positioned light sources, the latter being taken into account due to the angular offset of the reflection regions of the different light modules relative to each other.
- all lighting modules are constructed identically. This means that in addition to the reflection areas of the lighting modules, the other components of the lighting modules are constructed identically. This represents the simplest construction of the signaling device, because despite different light sources with possibly different light information only a single component of a light module must be made many times.
- the lighting modules are stacked one above the other along the main axis of the signaling device and arranged in a rotationally offset by a predetermined angle, as explained.
- the lighting modules can be colored differently or contain differently colored color filters. Especially for multi-source or multi-color devices results in this way a uniform, cost-effective manufacturing process of the lighting modules.
- the geometry of the lighting modules can be standardized, with a geometric relation to the light sources is made purely by rotational offset of the reflection regions of the lighting modules.
- bundling means are arranged on the signaling device for bundling and / or guiding the light generated by the respective light sources in such a way that a light dome oriented essentially in a beam direction parallel to the main axis of the signaling device is formed for each light source.
- the bundling means mentioned may be, for example, diaphragms, screens, lenses, optical waveguides, and so on.
- the lighting modules of the signaling device are each formed of a solid luminous element, in which the reflection regions are introduced.
- the luminous element can be formed, for example, from a transparent composite, for example cast.
- the surfaces on which a luminous element adjoins another luminous element can be processed, for example polished, in order to reduce reflection losses or scattering losses and to improve the coupling properties of the light emitted by the light sources into the luminous elements.
- the signaling apparatus is set up for a low-loss passage of the light through the stacked luminous bodies toward a corresponding reflection area of a dedicated luminous body.
- a luminous body along its circumference perpendicular to the main axis have a surface which is specially adapted for a desired decoupling of the light from the lighting modules.
- a surface may, for example, have diffuse reflection properties or a matt or frosted glass surface.
- the reflection areas in the lighting modules are formed by optical mirror elements.
- the reflection regions in the light modules could also be formed by optical defects, which lead to a refraction or reflection of an incident light beam.
- transitions of different refractive indices may optionally be used in combination with the aforementioned measures in the lighting modules in order to achieve a deflection of an incident light beam in a direction of signaling.
- different implementations are conceivable within the scope of expert action.

- a light source 2a, 2b and 2c with appropriate electrical or electronics and corresponding leads from the foot area 4 has to be set up to the corresponding light module 3a, 3b and 3c.
- a construction is complicated because the lighting modules 3a, 3b and 3c have to be manufactured in different ways.
- separate electrics or electronics must be provided for each light source, and the light sources may also differ from each other.
- additional functions such as color changes, replacement light functions in the event of a failure of a light source, and so on, are here only with considerable design effort feasible.
- n or more different lighting modules are to be produced for n different color information of a corresponding signaling device.
- the control of the corresponding lighting modules 3a, 3b and 3c designed with appropriate signaling devices 1 consuming, because to each light module 3a, 3b and 3c appropriate leads are set up.

Description
Die Erfindung betrifft eine Signalisierungsvorrichtung für Befehls- und/oder Meldegeräte.The invention relates to a signaling device for command and / or signaling devices.
Signalisierungsvorrichtungen nach dem Stand der Technik weisen insbesondere mehrere Leuchtmodule auf, welche entlang einer Hauptachse der Signalisierungsvorrichtung gestapelt sind. In jedem Leuchtmodul ist dabei eine Lichtquelle angeordnet zur Erzeugung von Licht, welches aus dem Leuchtmodul in eine Signalisierungsrichtung nach außen abgestrahlt werden kann, um eine entsprechende Signalanzeige zu ermöglichen. Eine solche Signalisierungsvorrichtung nach dem Stand der Technik ist beispielsweise in
Derartige Signalisierungsvorrichtungen haben den Nachteil, dass sie relativ aufwändig in ihrer Herstellung sind, weil in jedem der Leuchtmodule eine Lichtquelle mit entsprechender Elektrik beziehungsweise Elektronik und elektrischen Zuleitungen eingerichtet werden muss. Insbesondere im Falle sogenannter Multifarben-Vorrichtungen, in denen mehrere Lichtfarben zur Anzeige gebracht werden, ergeben sich somit vielfältige Kombinationen unterschiedlich herzustellender Leuchtmodule mit entsprechenden Lichtquellen. Ferner ist auch eine Konstruktion solcher Signalisierungsvorrichtungen vor dem Hintergrund der sogenannten Ersatzlichtfunktion im Falle eines Ausfalls einer Lichtquelle aufwändig und teuer.Such signaling devices have the disadvantage that they are relatively expensive to manufacture, because in each of the lighting modules, a light source with appropriate electrical or electronics and electrical leads must be established. In particular, in the case of so-called multi-color devices, in which a plurality of light colors are displayed, thus resulting in a variety of combinations of different manufactured lighting modules with corresponding light sources. Furthermore, a construction of such signaling devices against the background of the so-called replacement light function in the event of failure of a light source is expensive and expensive.
Insbesondere bei Signalsäulen, die Leitungen oberhalb von Kleinspannungen (5 V, 12 V) führen, zum Beispiel Netzspannung von 110 V oder 230 V, ist bei der Weiterleitung der elektrischen Signale von der Grundeinheit zu den einzelnen, gestapelten Leuchtmodulen auf eine berührungssichere Isolation zu achten. Zum Beispiel dürfen bei Abnahme eines Moduls keine spannungsführenden Teile eine Berührung zulassen.In particular, in signal towers, the lines above low voltages (5 V, 12 V) lead, for example, mains voltage of 110 V or 230 V, care must be taken in the transmission of the electrical signals from the base unit to the individual, stacked lighting modules on a shock-proof isolation , For example, allowed if a module is removed, no voltage-carrying parts allow contact.
Es existieren bereits andere Lösungen von Signalisierungsvorrichtungen, welche die vorgenannten Nachteile teilweise umgehen.There are already other solutions of signaling devices that partially circumvent the aforementioned disadvantages.
Eine Signalisierungsvorrichtung gemäß einer solchen letztgenannten Lösung weist eine Basiseinheit auf, umfassend zumindest zwei Lichtquellen zur jeweiligen Erzeugung von Licht, die beabstandet zueinander an der Basiseinheit angeordnet sind. Ferner weist die Signalisierungsvorrichtung zumindest zwei Leuchtmodule auf, welche entlang einer Hauptachse der Signalisierungsvorrichtung gestapelt und in Wirkverbindung mit den Lichtquellen sind, sodass von den Lichtquellen erzeugtes Licht in einer Strahlrichtung parallel zur Hauptachse in die Leuchtmodule eingekoppelt wird. Ferner weisen die Leuchtmodule jeweils einen Reflexionsbereich auf zur zumindest teilweisen Reflexion des in die Leuchtmodule eingekoppelten Lichts in einer Signalisierungsrichtung, siehe
Derartige Signalisierungsvorrichtungen haben gegenüber sonstigen Lösungen aus dem Stand der Technik den Vorteil, dass die Lichtquellen nicht mehr einzeln in den jeweiligen Leuchtmodulen verbaut werden müssen, wobei Lichtquellen mit ihrer Elektrik beziehungsweise Elektronik in eine Basiseinheit verlegt sind. Mittels optischer Lichtführungen, zum Beispiel Lichtwellenleiter, wird das Licht an eine entsprechende Abstrahlposition geleitet und dort vermittels entsprechender Reflexionsbereiche in einer Signalisierungsrichtung nach außen abgestrahlt.Such signaling devices have the advantage over other solutions from the prior art that the light sources no longer have to be individually installed in the respective lighting modules, wherein light sources are laid with their electrics or electronics in a base unit. By means of optical light guides, for example optical waveguides, the light is conducted to a corresponding emission position and emitted there by means of corresponding reflection regions in a signaling direction to the outside.
Nachteilig an diesen Lösungen bleibt jedoch die relativ aufwändige Konstruktion der Signalisierungsvorrichtungen in Bezug auf die einzelnen Leuchtmodule, welche in der Regel geometrisch unterschiedlich konstruierte Einzelelemente aufweisen, um entlang der Signalisierungsvorrichtung Lichtinformation unterschiedlicher und/oder örtlich verteilter Lichtquellen zu empfangen und an der gewollten Abstrahlposition der Signalisierungsvorrichtung nach außen abzustrahlen. Ein gewisser Nachteil im Konstruktionsaufwand bleibt somit auch bei Signalisierungsvorrichtungen der letztgenannten Art.A disadvantage of these solutions, however, remains the relatively complex construction of the signaling devices with respect to the individual lighting modules, which typically have geometrically differently constructed individual elements to receive along the signaling device light information different and / or locally distributed light sources and at the desired emission position of the signaling device to radiate to the outside. A certain disadvantage in the Design effort thus remains even with signaling devices of the latter type.
Es ist somit eine Aufgabe der Erfindung, Signalisierungsvorrichtungen in ihrer Konstruktion weiter zu vereinfachen und dennoch die gewünschten Funktionalitäten wie Farbänderungen, Farbunterschiede, Ersatzlichtfunktionen sowie Multifarben-Vorrichtungen zu erhalten.It is thus an object of the invention to further simplify signaling devices in their construction and still obtain the desired functionalities such as color changes, color differences, spare light functions and multi-color devices.
Diese Aufgabe wird durch eine Signalisierungsvorrichtung der genannten Art dadurch gelöst, dass ein jeweiliger Reflexionsbereich eines Leuchtmoduls in Umfangsrichtung des entsprechenden Leuchtmoduls senkrecht zur Hauptachse der Signalisierungsvorrichtung lediglich einen Teilbereich des Leuchtmoduls einnimmt, der kleiner ist als der Gesamtumfang des Leuchtmoduls und dass ein Reflexionsbereich eines Leuchtmoduls relativ zu einem Reflexionsbereich eines anderen Leuchtmoduls um einen vorbestimmten Winkel senkrecht zur Hauptachse versetzt angeordnet ist, wobei die Reflexionsbereiche den gleichen radialen Abstand zur Hauptachse aufweisen.This object is achieved by a signaling device of the type mentioned in that a respective reflection region of a light module in the circumferential direction of the corresponding light module perpendicular to the main axis of the signaling device occupies only a portion of the light module, which is smaller than the total circumference of the light module and that a reflection region of a light module relative is arranged offset to a reflection region of another light-emitting module by a predetermined angle perpendicular to the main axis, wherein the reflection regions have the same radial distance from the main axis.
Außerhalb des Reflexionsbereichs des Leuchtmoduls wird Licht, das parallel zur Hauptachse auf das Leuchtmodul fällt, in Richtung der Hauptachse weitergeleitet, zum Beispiel auf ein weiteres, sich anschließendes Leuchtmodul. Dies kann insbesondere in Bereichen vorgesehen sein, die im selben radialen Abstand und mit einem vorbestimmten Winkel angeordnet sind, so dass das Licht in dem oder den sich anschließenden Leuchtmodul(en) auf den sich dort befindlichen Reflexionsbereich trifft.Outside the reflection region of the light module, light which is incident on the light module parallel to the main axis is forwarded in the direction of the main axis, for example to a further, subsequent light module. This can be provided in particular in areas which are arranged at the same radial distance and at a predetermined angle, so that the light in the adjoining lighting module (s) meets the reflection area located there.
Die Weiterleitung des Lichts in den Leuchtmodulen kann zum Beispiel durch Bohrungen parallel zur Hauptachse erfolgen. Die Wände der Bohrungen haben dabei reflektierende Eigenschaften, wie sie zum Beispiel durch ein Polieren der Oberfläche des Materials der Leuchtmodule oder durch eine reflektierende Beschichtung erfolgen kann. Beispielsweise können die Bohrungen auch Lichtleiter aus lichtführendem Material enthalten, wie zum Beispiel einen transparenten Kunststoff oder Glas, das einen vom Material der Leuchtmodule unterschiedlichen Brechungsindex hat, so dass es an der Oberfläche zum Material der Leuchtmodule zur Reflexion kommt.The forwarding of the light in the lighting modules can be done for example by drilling parallel to the main axis. The walls of the holes in this case have reflective properties, as can be done for example by polishing the surface of the material of the lighting modules or by a reflective coating. For example, the holes may also contain light guides made of light-guiding material, such as a transparent plastic or glass, which has a different refractive index of the material of the lighting modules, so that it comes to the surface to the material of the lighting modules for reflection.
Eine derartige Signalisierungsvorrichtung hat gegenüber den Lösungen aus dem Stand der Technik verschiedene Vorteile. Ein Vorteil besteht, wie bereits erläutert, darin, dass die Elektrik beziehungsweise Elektronik zur Lichterzeugung in den Leuchtmodulen selbst nicht mehr notwendig ist. Vielmehr ist die Lichterzeugung vermittels Lichtquellen in eine Basiseinheit verlegt, so dass Licht an zentraler Stelle erzeugt und mittels der Leuchtmodule und Reflexionsbereiche an eine jeweilige Abstrahlposition in einem Leuchtmodul geleitet wird. Auf diese Weise ergibt sich ein einfacher Aufbau im Hinblick auf die Lichtquellen und deren elektrischer Anbindung.Such a signaling device has several advantages over the prior art solutions. An advantage, as already explained, is that the electrics or electronics for generating light in the lighting modules themselves is no longer necessary. Rather, the light generation is moved by means of light sources in a base unit, so that light is generated at a central location and directed by the light modules and reflection areas to a respective emission position in a light module. In this way, a simple structure with regard to the light sources and their electrical connection.
Der eingesparte Platz kann dazu genutzt werden, eine große Anzahl von Bohrungen oder Lichtleitern parallel zur Hauptachse unterzubringen. Während heutige Signalsäulen üblicherweise bis zu 5 Leuchtmodulen enthalten, ist auf diese Weise eine größere Anzahl denkbar, zum Beispiel, 8, 12 oder auch 24 Module.
Zudem kann die Bauhöhe reduziert werden. Heutige Leuchtmodule haben eine Höhe von 60 - 70 mm. Die Bauhöhe kann zum Beispiel auf 20 mm reduziert werden, da keine elektrischen Bauelemente in das Leuchtmodul eingebaut werden müssen. Die so erzielbare engere Anordnung der einzelnen Signalisierungsbereiche ermöglicht eine Unterbringung von mehr Signalisierungen bei vergleichbarer Bauhöhe und damit auch neue Signalisierungen, wie zum Beispiel ein Lauflicht im Signalisierungsbereich oder innerhalb eines Teils des Signalisierungsbereichs.The saved space can be used to accommodate a large number of holes or light guides parallel to the main axis. While today's signal towers usually contain up to 5 lighting modules, a larger number is conceivable in this way, for example, 8, 12 or even 24 modules.
In addition, the height can be reduced. Today's lighting modules have a height of 60 - 70 mm. The height can be reduced to 20 mm, for example, since no electrical components must be installed in the light module. The thus achievable tighter arrangement of the individual signaling areas allows a housing of more signaling at comparable height and thus new signaling, such as a running light in the signaling area or within a portion of the signaling area.
Zudem besteht bei diesen Signalisierungsvorrichtungen der Vorteil, dass Lichtinformationen von verschiedenen örtlich verteilten Lichtquellen rein aufgrund geometrischer Relation zu zugehörigen Reflexionsbereichen der Leuchtmodule auf einfache Weise sowohl unterschieden als auch separat voneinander an eine entsprechende Abstrahlposition geleitet werden können.In addition, with these signaling devices has the advantage that light information from different locally distributed light sources purely due to geometric relation to associated reflection regions of the lighting modules in a simple way both distinguish and can be routed separately from each other to a corresponding emission position.
Die Reflexionsbereiche der Leuchtmodule liegen aufgrund der gestapelten Anordnung der Leuchtmodule jeweils in einer separaten Ebene senkrecht zur Hauptachse. Eine Kodierung der Leuchtmodule mit vorbestimmten Lichtquellen ergibt sich rein durch einen Winkelversatz der Reflexionsbereiche der Leuchtmodule um einen vorbestimmten Winkel senkrecht zur Hauptachse der Signalisierungsvorrichtung, wobei die Reflexionsbereiche den gleichen radialen Abstand zur Hauptachse aufweisen. Auf diese Weise wird die Konstruktion der einzelnen Leuchtmodule deutlich vereinfacht. Der Begriff "um einen vorbestimmten Winkel senkrecht zur Hauptachse" bedeutet in diesem Kontext ein Versatz der Reflexionsbereiche um einen Winkel in einer Drehrichtung um die Hauptachse als Drehachse. In einer vorteilhaften Ausführungsform sind die Leuchtmodule rotationssymmetrisch ausgeführt. Alternativ sind jedoch auch andere Ausprägungen und Formgebungen denkbar.The reflection regions of the lighting modules are due to the stacked arrangement of the lighting modules in each case in a separate plane perpendicular to the main axis. An encoding of the lighting modules with predetermined light sources results purely by an angular offset of the reflection regions of the lighting modules by a predetermined angle perpendicular to the main axis of the signaling device, wherein the reflection regions have the same radial distance from the main axis. In this way, the construction of the individual lighting modules is significantly simplified. The term "at a predetermined angle perpendicular to the main axis" in this context means an offset of the reflection ranges by an angle in a rotational direction about the major axis as a rotation axis. In an advantageous embodiment, the lighting modules are designed rotationally symmetrical. Alternatively, however, other forms and shapes are conceivable.
Auf diese Weise macht die erläuterte Signalisierungsvorrichtung eine umständliche Konstruktion der Lichtführungen der verschiedenen Lichtquellen in Bezug zu entsprechenden Reflexionsbereichen an unterschiedlichen Positionen der Signalisierungsvorrichtung obsolet. Auch eine Behinderung oder Beeinträchtigung der Lichtführungen untereinander kann auf diese Weise vermieden werden. Insbesondere vorteilhaft gestaltet sich eine entsprechende Signalisierungsvorrichtung bei sogenannten Multifarben-Vorrichtungen, bei denen Lichtquellen und Lichtinformation unterschiedlicher Farben eingesetzt werden, zum Beispiel bei Ampelsignalanlagen der erläuterten Art. Die beschriebene Signalisierungsvorrichtung weist eine deutlich vereinfachte Konstruktion sowie einen vereinfachten und kostengünstigen Aufbau im Vergleich zu Lösungen des Stands der Technik auf.In this way, the illustrated signaling device obviates a cumbersome design of the light guides of the various light sources with respect to corresponding reflection areas at different positions of the signaling device. A disability or impairment of the light guides with each other can be avoided in this way. Particularly advantageous is a corresponding signaling device designed in so-called multi-color devices in which light sources and light information of different colors are used, for example in traffic signal systems of the type described. The signaling device described has a significantly simplified construction and a simplified and inexpensive construction compared to solutions of State of the art.
Die um einen vorbestimmten Winkel senkrecht zur Hauptachse versetzt angeordneten Reflexionsbereiche der entsprechenden Leuchtmodule weisen gleichen radialen Abstand zur Hauptachse auf. Es ist denkbar, in einer alternativen Ausführungsform neben der Gruppe der erläuterten Reflexionsbereiche eine weitere Gruppe zusätzlicher Reflexionsbereiche vorzusehen, sodass in einem Leuchtmodul wenigstens zwei Reflexionsbereiche angeordnet sind. Die jeweiligen radialen Abstände der ersten Gruppe von Reflexionsbereichen und der zweiten Gruppe von Reflexionsbereichen bezüglich der Hauptachse können gleich, aber auch unterschiedlich sein. Innerhalb einer Gruppe von Reflexionsbereichen ist der radiale Abstand zur Hauptachse jedoch gleich. Entsprechende Gruppen von Reflexionsbereichen können z.B. "ringförmig" ausgehend von der Hauptachse in unterschiedlichem radialem Abstand zur Hauptachse angeordnet sein.The offset by a predetermined angle perpendicular to the main axis arranged reflection regions of the corresponding lighting modules have the same radial distance from the main axis. It is conceivable to provide, in an alternative embodiment, a further group of additional reflection regions in addition to the group of the explained reflection regions, so that in a light-emitting module at least two reflection areas are arranged. The respective radial distances of the first group of reflection areas and the second group of reflection areas with respect to the main axis may be the same, but also different. Within a group of reflection areas, however, the radial distance to the main axis is the same. Corresponding groups of reflection regions can be arranged, for example, "annularly" starting from the main axis at a different radial distance from the main axis.
Derartige Ausführungsformen können vorteilhaft bei der Anordnung der einzelnen Lichtquellen auf der Basiseinheit der Signalisierungsvorrichtung sein und ermöglichen eine gewisse Flexibilität in der Ausgestaltung. Vorteilhaft kann auf diese Weise auch eine Ersatzlichtfunktonalität eingerichtet werden, bei der das Licht von mehreren Lichtbereichen (zum Beispiel von zwei Lichtbereichen) in einem Leuchtmodul ausgekoppelt wird. Auf diese Weise wird bei Ausfall eines Leuchtelements noch das Licht wenigstens eines weiteren Leuchtelements in dem Leuchtmodul ausgekoppelt, so dass die Signalisierungsfunktion auch in diesem Fall gegeben ist. Auf diese Weise kann die Ausfallsicherheit der Signalsäule erhöht werden.Such embodiments may be advantageous in the arrangement of the individual light sources on the base unit of the signaling device and allow some flexibility in the design. Advantageously, a Ersatzlichtfunktonalität be set up in this way, in which the light of several light areas (for example, two light areas) is coupled in a light module. In this way, in the event of failure of a luminous element, the light of at least one further luminous element in the luminous module is coupled out, so that the signaling function is also provided in this case. In this way, the reliability of the signal tower can be increased.
Alternativ kann die Nutzung mehrerer Reflexionsbereiche im Modul weitere Anwendungen ermöglichen. So kann zum Beispiel verschiedenfarbiges Licht über unterschiedliche Reflexionsbereiche eingekoppelt werden, so dass Mischfarben möglich sind. Durch zeitlich variable Ansteuerung der Leuchtmittel lässt sich die Helligkeit oder Intensität der einzelnen Lichtfarben steuern und so die Mischfarbe verändern. Auf diese Weise können auch weitere Leuchteffekte erzielt werden, wie zum Beispiel ein mehrfarbiges Blinken.Alternatively, using multiple reflective areas in the module may allow for additional applications. Thus, for example, differently colored light can be coupled in via different reflection regions, so that mixed colors are possible. By timely variable activation of the lamps, the brightness or intensity of the individual light colors can be controlled and thus change the mixed color. In this way, other lighting effects can be achieved, such as a multi-colored flashing.
In einer vorteilhaften Ausführungsform sind die Reflexionsbereiche der Leuchtmodule in einer Richtung parallel zur Hauptachse jeweils in Deckung mit zumindest einer der Lichtquellen angeordnet, um abgestrahltes Licht der entsprechenden Lichtquelle zu reflektieren. Auf diese Weise ergibt sich eine einfache Zuordnung eines entsprechenden Reflexionsbereiches in einem Leuchtmodul zu einer oder mehreren Lichtquellen, welche auf der Basiseinheit örtlich entfernt von dem jeweiligen Leuchtmodul eingerichtet sind. Vorteilhaft stimmt somit eine Anordnung der Lichtquellen auf der Basiseinheit überein mit einer rotatorisch versetzten Anordnung der Reflexionsbereiche in den einzelnen Leuchtmodulen. Bis zu einem entsprechenden Reflexionsbereich wird das von einer Lichtquelle erzeugte Licht durch die einzelnen Leuchtmodule im Wesentlichen entlang einer Richtung parallel zur Hauptachse der Vorrichtung transportiert. An geeigneter Stelle erfolgt dann die Reflexion und Abstrahlung des eingekoppelten Lichts nach außen in eine Signalisierungsrichtung.In an advantageous embodiment, the reflection regions of the lighting modules are arranged in a direction parallel to the main axis in each case in coincidence with at least one of the light sources in order to reflect emitted light of the corresponding light source. In this way, a simple assignment of a corresponding reflection range in a light module results in a or a plurality of light sources, which are arranged on the base unit locally remote from the respective light module. Advantageously, therefore, an arrangement of the light sources on the base unit coincides with a rotationally offset arrangement of the reflection areas in the individual lighting modules. Up to a corresponding reflection region, the light generated by a light source is transported by the individual lighting modules substantially along a direction parallel to the main axis of the device. At a suitable location, the reflection and emission of the coupled-in light then takes place to the outside in a signaling direction.
So kann die Lichtinformation einer ersten Lichtquelle, beispielsweise in einer Strahlrichtung parallel zur Hauptachse, zu einem ersten Reflexionsbereich eines ersten Leuchtmoduls transportiert werden, wobei die Lichtinformation einer zweiten Lichtquelle, die örtlich versetzt zur ersten Lichtquelle angeordnet ist, in einer Strahlrichtung parallel zur Hauptachse zu einem zweiten Reflexionsbereich eines zweiten Leuchtmoduls transportiert wird. Eine derartige Konstruktion unterstützt einen einfachen Aufbau einer Signalisierungsvorrichtung und ermöglicht dennoch eine gewünschte Funktionalität eines Unterscheidens unterschiedlicher Lichtinformationen an unterschiedlichen Abstrahlpositionen an der Signalisierungsvorrichtung.Thus, the light information of a first light source, for example in a beam direction parallel to the main axis, are transported to a first reflection region of a first light module, wherein the light information of a second light source, which is arranged offset from the first light source in a beam direction parallel to the main axis to a second reflection region of a second light-emitting module is transported. Such a construction supports a simple structure of a signaling device and yet allows a desired functionality of distinguishing different light information at different emission positions on the signaling device.
In einer vorteilhaften Ausführungsform sind sämtliche Reflexionsbereiche der Leuchtmodule identisch ausgeführt. Dies vereinfacht die Konstruktion der Leuchtmodule weiter. Lichtinformationen der unterschiedlichen Lichtquellen werden auf einheitliche Art und Weise in der Vorrichtung geleitet und nach außen hin in eine Signalisierungsrichtung reflektiert. Dabei kann eine einheitliche Konstruktion der Reflexionsbereiche für dennoch unterschiedlich positionierte Lichtquellen vorgesehen werden, wobei letzteres aufgrund des Winkelversatzes der Reflexionsbereiche der unterschiedlichen Leuchtmodule zueinander berücksichtigt wird.In an advantageous embodiment, all reflection regions of the lighting modules are identical. This further simplifies the construction of the lighting modules. Light information of the different light sources are uniformly conducted in the device and reflected outwardly in a signaling direction. In this case, a uniform construction of the reflection regions can be provided for nevertheless differently positioned light sources, the latter being taken into account due to the angular offset of the reflection regions of the different light modules relative to each other.
Gemäß einer vorteilhaften Ausführungsform sind sämtliche Leuchtmodule identisch aufgebaut. Das bedeutet, dass neben den Reflexionsbereichen der Leuchtmodule auch die anderen Komponenten der Leuchtmodule identisch aufgebaut sind. Dies stellt die einfachste Konstruktion der Signalisierungsvorrichtung dar, weil trotz unterschiedlicher Lichtquellen mit gegebenenfalls unterschiedlichen Lichtinformationen nur ein einziges Bauteil eines Leuchtmoduls vielfach gefertigt werden muss. Die Leuchtmodule werden gestapelt übereinander entlang der Hauptachse der Signalisierungsvorrichtung und um einen vorbestimmten Winkel rotatorisch versetzt angeordnet, wie erläutert. Die Leuchtmodule können dabei unterschiedlich gefärbt sein oder unterschiedlich gefärbte Farbfilter enthalten. Gerade für Multiquellen- beziehungsweise Multifarben-Vorrichtungen ergibt sich auf diese Weise ein einheitlicher, kostengünstiger Fertigungsprozess der Leuchtmodule. Somit entfallen bei einer derartigen Ausführungsform nicht nur die Elektrik beziehungsweise Elektronik und/oder elektrische Zuleitungen in die einzelnen Leuchtmodule für eine Lichterzeugung. Auch die Geometrie der Leuchtmodule kann vereinheitlicht werden, wobei eine geometrische Relation zu den Lichtquellen rein durch rotatorischen Versatz der Reflexionsbereiche der Leuchtmodule hergestellt wird.According to an advantageous embodiment, all lighting modules are constructed identically. This means that in addition to the reflection areas of the lighting modules, the other components of the lighting modules are constructed identically. This represents the simplest construction of the signaling device, because despite different light sources with possibly different light information only a single component of a light module must be made many times. The lighting modules are stacked one above the other along the main axis of the signaling device and arranged in a rotationally offset by a predetermined angle, as explained. The lighting modules can be colored differently or contain differently colored color filters. Especially for multi-source or multi-color devices results in this way a uniform, cost-effective manufacturing process of the lighting modules. Thus, in such an embodiment, not only the electrical system or electronics and / or electrical supply lines in the individual lighting modules for a light generation omitted. The geometry of the lighting modules can be standardized, with a geometric relation to the light sources is made purely by rotational offset of the reflection regions of the lighting modules.
Gemäß einer vorteilhaften Ausführungsform sind an der Signalisierungsvorrichtung Bündelungsmittel eingerichtet zur Bündelung und/oder Führung des von den jeweiligen Lichtquellen erzeugten Lichts derart, dass für jede Lichtquelle ein im Wesentlichen in einer Strahlrichtung parallel zur Hauptachse der Signalisierungsvorrichtung orientierter Lichtdom gebildet ist. Die genannten Bündelungsmittel können zum Beispiel Blenden, Raster, Linsen, Lichtwellenleiter, und so weiter sein. Vermittels der Bündelungsmittel ist eine möglichst verlustarme Lichtstrahlerzeugung und Weiterleitung zum Einkoppeln des erzeugten Lichtes in die entsprechenden Leuchtmodule gewährleistet. Ferner wird die Streulichterzeugung reduziert beziehungsweise unterdrückt, wodurch eine möglichst störungsfreie und exakte Abstrahlung von Licht an den entsprechenden Leuchtmodulen über die Reflexionsbereiche erzielt werden kann. Dies unterstützt eine gute Signalisierungseigenschaft der Signalisierungsvorrichtung.According to an advantageous embodiment, bundling means are arranged on the signaling device for bundling and / or guiding the light generated by the respective light sources in such a way that a light dome oriented essentially in a beam direction parallel to the main axis of the signaling device is formed for each light source. The bundling means mentioned may be, for example, diaphragms, screens, lenses, optical waveguides, and so on. By means of the bundling means a low-loss light beam generation and forwarding for coupling the generated light is ensured in the corresponding lighting modules. Furthermore, the generation of scattered light is reduced or suppressed, whereby the most trouble-free and accurate radiation of light at the corresponding lighting modules can be achieved via the reflection regions. This supports a good signaling characteristic of the signaling device.
In einer vorteilhaften Ausführung sind die Leuchtmodule der Signalisierungsvorrichtung jeweils aus einem massiven Leuchtkörper gebildet, in den die Reflexionsbereiche eingebracht sind. Der Leuchtkörper kann zum Beispiel aus einem transparenten Verbundstoff gebildet sein, zum Beispiel gegossen sein. Unter Umständen können die Flächen, an denen ein Leuchtkörper an einen anderen Leuchtkörper angrenzt, bearbeitet sein, zum Beispiel poliert sein, um Reflexionsverluste oder Streuverluste zu vermindern und Einkoppeleigenschaften des von den Lichtquellen abgestrahlten Lichtes in die Leuchtkörper zu verbessern. Auf diese Weise ist die Signalisierungsvorrichtung trotz einer gestapelten Anordnung mehrerer Leuchtmodule beziehungsweise Leuchtkörper für ein verlustarmes Durchleiten des Lichtes durch die gestapelten Leuchtkörper hin zu einem entsprechenden Reflexionsbereich eines dezidierten Leuchtkörpers eingerichtet.In an advantageous embodiment, the lighting modules of the signaling device are each formed of a solid luminous element, in which the reflection regions are introduced. The luminous element can be formed, for example, from a transparent composite, for example cast. In certain circumstances, the surfaces on which a luminous element adjoins another luminous element can be processed, for example polished, in order to reduce reflection losses or scattering losses and to improve the coupling properties of the light emitted by the light sources into the luminous elements. In this way, despite a stacked arrangement of a plurality of lighting modules or luminous bodies, the signaling apparatus is set up for a low-loss passage of the light through the stacked luminous bodies toward a corresponding reflection area of a dedicated luminous body.
Gemäß einer vorteilhaften Ausführungsform kann ein Leuchtkörper entlang seines Umfangs senkrecht zur Hauptachse eine Oberfläche aufweisen, die speziell für ein gewünschtes Auskoppeln des Lichtes aus den Leuchtmodulen eingerichtet ist. Eine derartige Oberfläche kann zum Beispiel diffuse Reflexionseigenschaften oder eine matte beziehungsweise Milchglas-Oberfläche aufweisen. Auf diese Weise kann gewährleistet werden, dass Licht, welches an den Reflexionsbereichen der Leuchtmodule nach außen in Richtung einer Signalisierungsrichtung reflektiert wird, entlang des gesamten Umfangs des Leuchtkörpers geleitet und schließlich nach außen abgestrahlt wird. Auf diese Weise kann ein gleichmäßiges Erleuchten beziehungsweise Ausleuchten eines Leuchtmoduls beziehungsweise Leuchtkörpers entlang des Umfangs erzeugt werden, was zu einem gleichmäßigen Erscheinungsbild einer Signalisierung führt. Somit ist eine Signalisierung durch die Signalisierungsvorrichtung unabhängig von einem Blickwinkel und/oder einer Blickorientierung auf die Signalisierungsvorrichtung hin. Insbesondere im industriellen Umfeld, in dem eine 360°-Betrachtung entsprechender Signalisierungsvorrichtungen notwendig beziehungsweise vorteilhaft sein kann, erscheint dies günstig.According to an advantageous embodiment, a luminous body along its circumference perpendicular to the main axis have a surface which is specially adapted for a desired decoupling of the light from the lighting modules. Such a surface may, for example, have diffuse reflection properties or a matt or frosted glass surface. In this way it can be ensured that light, which is reflected at the reflection regions of the lighting modules to the outside in the direction of a signaling direction, guided along the entire circumference of the luminous body and finally emitted to the outside. In this way, a uniform illumination or illumination of a light module or luminous body along the circumference can be generated, resulting in a uniform appearance of signaling. Thus, signaling by the signaling device is independent of a viewing angle and / or a gaze orientation towards the signaling device. In particular, in the industrial environment, in which a 360 ° consideration of corresponding signaling devices may be necessary or advantageous, this seems favorable.
In einer vorteilhaften Ausführungsform sind die Reflexionsbereiche in den Leuchtmodulen durch optische Spiegelelemente gebildet. Alternativ könnten die Reflexionsbereiche in den Leuchtmodulen auch durch optische Störstellen gebildet sein, welche zu einer Brechung beziehungsweise Reflexion eines einfallenden Lichtstrahls führen. Gegebenenfalls können in den Leuchtmodulen auch Übergänge unterschiedlicher Brechungsindizes gegebenenfalls kombiniert mit den vorgenannten Maßnahmen eingesetzt werden, um ein Ablenken eines einfallenden Lichtstrahls hin in eine Signalisierungsrichtung zu erzielen. Hier sind im Rahmen des fachmännischen Handelns unterschiedliche Realisierungen denkbar.In an advantageous embodiment, the reflection areas in the lighting modules are formed by optical mirror elements. Alternatively, the reflection regions in the light modules could also be formed by optical defects, which lead to a refraction or reflection of an incident light beam. Optionally, transitions of different refractive indices may optionally be used in combination with the aforementioned measures in the lighting modules in order to achieve a deflection of an incident light beam in a direction of signaling. Here, different implementations are conceivable within the scope of expert action.
Weitere vorteilhafte Ausgestaltungen sind in der nachfolgenden Figurenbeschreibung beziehungsweise in den Unteransprüchen offenbart.Further advantageous embodiments are disclosed in the following description of the figures or in the subclaims.

Der Nachteil einer derartigen Lösung besteht darin, dass in jedem Leuchtmodul 3a, 3b und 3c eine Lichtquelle 2a, 2b und 2c mit entsprechender Elektrik beziehungsweise Elektronik und entsprechenden Zuleitungen aus dem Fußbereich 4 hin zum entsprechenden Leuchtmodul 3a, 3b und 3c eingerichtet werden muss. Insbesondere bei Multifarben-Vorrichtungen, welche unterschiedliche Farbtöne durch die Leuchtmodule 3a, 3b und 3c repräsentieren, gestaltet sich eine derartige Konstruktion aufwändig, weil die Leuchtmodule 3a, 3b und 3c auf unterschiedliche Weise gefertigt werden müssen. Zum Beispiel muss für jede Lichtquelle eine separate Elektrik beziehungsweise Elektronik vorgesehen sein, wobei sich auch die Lichtquellen untereinander unterscheiden können. Auch zusätzliche Funktionen, wie Farbänderungen, Ersatzlichtfunktionen im Falle eines Ausfalls einer Lichtquelle, und so weiter, sind hier nur mit erheblichem Konstruktionsaufwand realisierbar. In der Regel sind für n unterschiedliche Farbinformationen einer entsprechenden Signalisierungsvorrichtung n oder mehr unterschiedliche Leuchtmodule zu fertigen. Dies bedeutet nicht zuletzt einen erheblichen Kostenaufwand in der Fertigung einer entsprechenden Signalisierungsvorrichtung 1. Auch die Ansteuerung der entsprechenden Leuchtmodule 3a, 3b und 3c gestaltet sich bei entsprechenden Signalisierungsvorrichtungen 1 aufwändig, weil zu jedem Leuchtmodul 3a, 3b und 3c entsprechende Zuleitungen einzurichten sind.The disadvantage of such a solution is that in each

Insbesondere bei Multifarben-Vorrichtungen, in denen die Lichtquellen 2a, 2b und 2c unterschiedliche Farbinformationen repräsentieren, können somit diese drei unterschiedlichen Farben entsprechend durch die drei Leuchtmodule 3a, 3b und 3c wiedergegeben werden.Thus, the illumination module 3a shines with a light information radiated from the light source 2a, in particular color information, while the illumination module 3b shines with light information or color information of the light source 2b and the

Je nach gewünschter Konfiguration einer Signalisierungsvorrichtung 1 muss lediglich eine vorbestimmte Anzahl n an Leuchtmodulen übereinandergestapelt und derart um vorbestimmte Winkel rotatorisch versetzt werden, dass ein jeweiliges Leuchtmodul in Wirkverbindung mit einer Lichtquelle gebracht wird und das erzeugte Licht vermittels des entsprechenden Reflexionsbereiches im Leuchtmodul reflektiert und nach außen abgestrahlt werden kann.Depending on the desired configuration of a signaling device 1, only a predetermined number n of lighting modules must be stacked and rotated by predetermined angle so that a respective light module is brought into operative connection with a light source and the generated light reflected by means of the corresponding reflection region in the light module and to the outside can be radiated.
Es ist auch denkbar, Reflexionsbereiche der Leuchtmodule derart auszuführen, dass diese Licht von mehreren Lichtquellen reflektieren. Hierbei wäre es denkbar, dass Mischfarben der einzelnen Lichtquellen erzeugt und an den entsprechenden Leuchtmodulen der Signalisierungsvorrichtung 1 nach außen abgestrahlt werden. Auch eine Ersatzlichtfunktion kann auf diese Weise realisiert werden.It is also conceivable to design reflection regions of the lighting modules in such a way that they reflect light from a plurality of light sources. In this case, it would be conceivable that mixed colors of the individual light sources are generated and emitted to the corresponding illumination modules of the signaling device 1 to the outside. A replacement light function can also be realized in this way.
Die Reflexionsbereiche 6a, 6b und 6c sind derart ausgeführt, dass sie jeweils in Umfangsrichtung U senkrecht zur aus der Bildebene herausführenden Hauptachse A lediglich einen Teilbereich T des Leuchtmoduls, hier 3a, einnehmen, der kleiner ist als der Gesamtumfang des Leuchtmoduls 3a. Auf diese Weise stellen die Reflexionsbereiche 6a, 6b und 6c diskrete Bereiche dar, die an einer vorbestimmten Stelle in einem Leuchtmodul beziehungsweise relativ zur gesamten Signalisierungsvorrichtung 1 diskret angeordnet sind. Wie bereits in Zusammenhang mit
Auf diese Weise ergibt sich rein durch rotatorischen Versatz der Leuchtmodule 3a, 3b und 3c mit ihren jeweiligen Reflexionsbereichen 6a, 6b und 6c (vergleiche
Einzige Unterschiede bestehen in der Formgebung der jeweiligen Reflexionsbereiche 6a, 6b und 6c, welche in
In nicht dargestellten Ausführungsformen kann eine Signalisierungsvorrichtung 1 der erläuterten Art auch Lichtquellen aufweisen, die auf einer Basiseinheit derart angeordnet sind, dass sie nicht in Deckung zu entsprechenden Reflexionsbereichen 6a, 6b und 6c von Leuchtmodulen 3a, 3b und 3c eingerichtet sind. Hierbei ist denkbar, dass von Lichtquellen abgestrahltes Licht über entsprechende Lichtwellenleiter derart zu den Leuchtmodulen 3a, 3b und 3c geführt wird, dass das Licht in Strahlrichtung R1, R2 beziehungsweise R3 parallel zur Hauptachse A (vergleiche
Ferner ist über die dargestellten Ausführungsbeispiele hinaus denkbar, eine Vielzahl von Leuchtmodulen mit entsprechenden Reflexionsbereichen in geometrischer Relation zu entsprechenden Lichtquellen anzuordnen, wobei die geometrische Ausführung, Anordnung sowie der geometrische Winkelversatz der Reflexionsbereiche der einzelnen Leuchtmodule zueinander je nach Anforderung im Rahmen des fachmännischen Wissens frei wählbar sind, ohne vom Kerngedanken der hier dargestellten Erfindung abzuweichen.Furthermore, it is beyond the illustrated embodiments also conceivable to arrange a plurality of light modules with corresponding reflection areas in geometric relation to corresponding light sources, the geometrical design, arrangement and the geometric angular offset of the reflection ranges of the individual lighting modules to each other as required within the scope of expert knowledge freely selectable are without deviating from the core idea of the invention presented here.
Ferner ist denkbar, in den Leuchtmodulen elektrische Leitungen, zum Beispiel Busleitungen, zu führen, welche jedoch für eine Lichterzeugung beziehungsweise Abstrahlung von Licht in den einzelnen Leuchtmodulen, wie erläutert, nicht notwendig sind. Vielmehr können derartige Leitungen für weitere elektrische Aufgaben einer Signalisierungsvorrichtung 1 der erläuterten Art herangezogen werden.Furthermore, it is conceivable to carry electrical lines, for example bus lines, in the lighting modules, which however are not necessary for light generation or radiation of light in the individual lighting modules, as explained. Rather, such lines can be used for further electrical tasks of a signaling device 1 of the type explained.
Vorteilhaft stellen Signalisierungsvorrichtungen 1 der erläuterten Art Signalsäulen, unter anderem zum Beispiel für Befehls- und/oder Meldegeräte jeglicher Art, dar.Advantageously, signaling devices 1 of the type described signal towers, including, for example, for command and / or signaling devices of any kind, is.
Die dargestellten Ausführungsformen sind lediglich beispielhaft gewählt.The illustrated embodiments are chosen by way of example only.
