Description

Beleuchtungsanordnung mit länglichem Leuchtengehäuse  Lighting arrangement with elongated luminaire housing
Die vorliegende Erfindung betrifft eine Beleuchtungsanordnung gemäß dem The present invention relates to a lighting arrangement according to the
Oberbegriff des Anspruchs 1 , welche ein längliches Leuchtengehäuse aufweist, das an einer Lichtaustrittsseite durch ein Lichtabgabeelement abgeschlossen ist, wobei innerhalb des Leuchtengehäuses Lichtquellen vorgesehen sind, die im Wesentlichen gleichmäßig verteilt über die gesamte Länge der Beleuchtungsanordnung hinweg angeordnet sind.  The preamble of claim 1, which has an elongate luminaire housing, which is closed at a light exit side by a light emitting element, wherein within the luminaire housing light sources are provided, which are arranged distributed substantially uniformly over the entire length of the illumination arrangement away.
Leuchten, die Bestandteil größerer Systeme, bspw. zum Beleuchten von Gebäuden oder Gebäudekomplexen sind, erfüllen unterschiedliche Aufgabenstellungen. Primär werden selbstverständlich Leuchten zur Raumbeleuchtung eingesetzt, um also bspw. bestimmte Räume oder Bereiche, deren Arbeitsplätze oder dergleichen entsprechend dem Bedürfnis der darin befindlichen Personen zu beleuchten. Ein anderer Typ von Leuchten, die in größeren Gebäuden, insbesondere in öffentlichen Gebäuden eingesetzt werden, sind sog. Rettungszeichenleuchten, deren Aufgabe nicht in dem Beleuchten eines bestimmten Bereichs besteht. Stattdessen dienen derartige Luminaires, which are part of larger systems, for example for illuminating buildings or building complexes, fulfill different tasks. Primarily, of course, lights are used for room lighting, so as to illuminate, for example, certain rooms or areas, their jobs or the like according to the needs of the people therein. Another type of luminaires used in larger buildings, especially in public buildings, are so-called escape-sign luminaires, the task of which is not to illuminate a certain area. Instead, serve such
Rettungszeichenleuchten dazu, einen Fluchtweg anzuzeigen, um Personen im Falle eines Notfalls ein sicheres Verlassen des Gebäudes zu ermöglichen. Üblicherweise weisen derartige Rettungszeichenleuchten ein Piktogramm auf, welches die Richtung des Rettungswegs darstellt und mit Hilfe von Lichtquellen beleuchtet wird. Denkbar wäre allerdings auch, durch entsprechend farbige Lichtquellen bzw. eine entsprechend farbige Lichtabgabe situationsbedingt die Richtung eines Fluchtwegs anzuzeigen. Escape sign lights to indicate an escape route to allow people in case of an emergency to leave the building safely. Usually, such escape sign lights have a pictogram, which represents the direction of the rescue route and is illuminated by means of light sources. However, it would also be conceivable to indicate the direction of an escape route by suitably colored light sources or a correspondingly colored light output depending on the situation.
Unabhängig davon, in welcher Weise derartige Rettungsleuchten oder Anzeigen von Fluchtwegen realisiert werden, kommen allerdings in der Regel zu diesem Zweck separate Leuchten zum Einsatz, welche unabhängig von den für die Raumbeleuchtung vorgesehenen Leuchten sind. Es handelt sich also um zusätzliche Elemente bzw. Regardless of the way in which such emergency lights or displays of escape routes are realized, however, separate lights are usually used for this purpose, which are independent of the lights provided for the room lighting. So these are additional elements or
Einheiten, die in dem Gebäude zu montieren sind und möglicherweise das Units to be mounted in the building and possibly the
Erscheinungsbild beeinträchtigen. Gleiches gilt für zusätzliche Komponenten, die oftmals für eine automatisierte Steuerung der Beleuchtung genutzt werden, also z.B. für Sensoren wie z.B. Helligkeitssensoren oder Anwesenheitssensoren. Auch hier handelt es sich oftmals um separate Elemente oder Einheiten, die zusätzlich zu den Leuchten für die Raumbeleuchtung und etwaigen Rettungszeichenleuchten montiert werden, also wiederum eigenen Platz beanspruchen und ggf. das Erscheinungsbild negativ beeinträchtigen. Affect appearance. The same applies to additional components that are often used for automated control of lighting, eg for sensors such as brightness sensors or presence sensors. Here too These are often separate elements or units that are mounted in addition to the lights for the room lighting and any escape route lights, so in turn claim your own space and possibly adversely affect the appearance.
Der vorliegenden Erfindung liegt deshalb die Aufgabenstellung zugrunde, ein neuartiges Konzept zum Realisieren einer Leuchte bzw. einer Beleuchtungsanordnung anzugeben, welches es ermöglicht, verschiedene Aufgabenstellungen der The present invention is therefore based on the object to provide a novel concept for realizing a lamp or a lighting arrangement, which makes it possible to different tasks of the
Beleuchtungstechnologie in einer gemeinsamen Anordnung zusammenzufassen. Lighting technology in a common arrangement to summarize.
Vorzugsweise sollen also möglichst wenig separate Einheiten in einem Raum zu montieren sein, welche trotz allem dann unterschiedliche Aufgabenstellungen erfüllen können. Preferably, therefore, as few separate units as possible should be mounted in a room which, in spite of everything, can then fulfill different tasks.
Die Aufgabe wird durch eine Beleuchtungsanordnung mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der abhängigen Ansprüche. The object is achieved by a lighting arrangement with the features of claim 1. Advantageous developments of the invention are the subject of the dependent claims.
Die erfindungsgemäße Lösung beruht auf dem Gedanken, eine Leuchte mit einem länglichen Leuchtengehäuse sowie darin angeordneten ersten Lichtquellen zu nutzen, welche der Raumbeleuchtung dienen und im Wesentlichen gleichmäßig verteilt über die gesamte Länge der Beleuchtungsanordnung hinweg angeordnet sind. Vorzugsweise sorgen diese Lichtquellen dafür, dass ein Lichtabstrahlelement, welches das The solution according to the invention is based on the idea of using a luminaire with an elongate luminaire housing and first light sources arranged therein which serve for the room lighting and are arranged substantially evenly distributed over the entire length of the illuminating arrangement. Preferably, these light sources ensure that a Lichtabstrahlelement which the
Leuchtengehäuse verschließt, bei Betrieb der Lichtquellen möglichst homogen bzw. gleichmäßig aufgehellt wird. Erfindungsgemäß sind allerdings innerhalb des Luminaire housing closes, is brightened as homogeneously or evenly when operating the light sources. According to the invention, however, within the
Leuchtengehäuses, insbesondere in Bereichen zwischen den ersten Lichtquellen zumindest eine weitere Lichtquelle und/oder ein Sensor angeordnet, wobei diese weitere Lichtquelle das Lichtaustrittselement der Leuchte in gleicher Weise zur Lichtabgabe nutzt bzw. der Sensor durch das Lichtabstrahlelement hindurch Daten für die gewünschte Beleuchtungssteuerung erfasst. Luminaire housing, in particular in areas between the first light sources arranged at least one further light source and / or a sensor, said further light source uses the light exit element of the lamp in the same way for light emission or the sensor detected by the Lichtabstrahlelement data for the desired lighting control.
Erfindungsgemäß wird also eine Beleuchtungsanordnung mit einem länglichen Leuchtengehäuse vorgeschlagen, welches an einer Lichtaustrittsseite durch ein Lichtaustrittselement abgeschlossen ist, wobei innerhalb des Leuchtengehäuses eine erste Gruppe von gleichartigen Lichtquellen vorgesehen ist, die im Wesentlichen gleichmäßig verteilt über die gesamte Länge der Beleuchtungsanordnung hinweg angeordnet sind. In Bereichen zwischen den Lichtquellen der ersten Gruppe sind zumindest eine weitere Lichtquelle und/oder ein Sensor angeordnet, welche das Abstrahlelement zur Lichtabgabe nutzt bzw. durch das Lichtabstrahlelement hindurch Sensordaten erfasst. According to the invention, therefore, a lighting arrangement with an elongated luminaire housing is proposed, which is completed at a light exit side by a light exit element, wherein within the luminaire housing, a first group of similar light sources is provided which substantially evenly distributed over the entire length of the lighting arrangement are arranged away. In regions between the light sources of the first group, at least one further light source and / or a sensor are arranged, which uses the emission element for emitting light or detects sensor data through the light emission element.
Letztendlich ergibt sich bei der erfindungsgemäßen Beleuchtungsanordnung also das Erscheinungsbild einer einzigen langgestreckten Leuchte, welche in üblicher Weise zur Raumbeleuchtung bzw. zur Beleuchtung von Gängen oder dergleichen genutzt werden kann. Zusätzlich werden allerdings nunmehr weitere Lichtquellen oderUltimately results in the lighting arrangement according to the invention thus the appearance of a single elongated lamp, which can be used in the usual way for room lighting or lighting corridors or the like. In addition, however, now more light sources or
Sensoren in die Leuchte integriert, die in gleicher Weise das Lichtabstrahlelement nutzen und bspw. zur Darstellung eines Fluchtweges bzw. zum Erfassen von Daten für die automatisierte Beleuchtungssteuerung genutzt werden können. Diese weiteren Komponenten beeinträchtigen allerdings das Erscheinungsbild der gesamten Sensors integrated into the lamp, which use the light emitting element in the same way and, for example, can be used to represent an escape route or to capture data for automated lighting control. However, these other components affect the appearance of the entire
Anordnung nunmehr nicht, da sie während eines Normalbetriebs von außen nicht erkennbar sind und - im Falle der zusätzlichen Lichtquellen - nur für den Fall, dass ihr Einsatz tatsächlich erforderlich ist, ein für einen Beobachter erkennbares Lichtsignal bzw. eine entsprechende Information abgeben. Vorzugsweise sind in Zwischenbereichen zwischen den Lichtquellen der erstenArrangement now not because they are not visible during normal operation from the outside and - in the case of additional light sources - only in the event that their use is actually required, emit a recognizable for an observer light signal or corresponding information. Preferably, in intermediate regions between the light sources of the first
Gruppe mehrere Lichtquellen angeordnet, die eine zweite Gruppe von Lichtquellen bilden, welche getrennt von der ersten Gruppe steuerbar ist. Die erste Gruppe dient, wie bereits erwähnt, vorzugsweise der allgemeinen Raumbeleuchtung. Es handelt sich also in diesem Fall um in der Regel Weißlichtquellen. Vorzugsweise handelt es sich um im Wesentlichen punktförmige Lichtquellen, also insbesondere um LEDs, besonders bevorzugt um Weißlicht-LEDs. Soll die zweite Gruppe von Lichtquellen dann der Darstellung der Richtung eines Fluchtwegs dienen, so handelt es sich vorzugsweise um farbige Lichtquellen, insbesondere um Lichtquellen, die bspw. Group a plurality of light sources arranged, which form a second group of light sources, which is controllable separately from the first group. The first group is, as already mentioned, preferably the general room lighting. So in this case it is usually white light sources. Preferably, these are essentially point-shaped light sources, that is to say in particular LEDs, particularly preferably white-light LEDs. If the second group of light sources then serve to represent the direction of an escape route, they are preferably colored light sources, in particular light sources, which, for example, can be used.
grünes Licht abgeben. Durch eine entsprechende, ggf. zeitlich aufeinander give the green light. By an appropriate, possibly temporally successive
abgestimmte Ansteuerung dieser farbigen Lichtquellen kann dann im Bedarfsfall die Richtung eines Fluchtwegs angezeigt werden, was bspw. durch die Darstellung eines in Richtung des Fluchtwegs wandernden grünen Leuchtpunkts erfolgt. Wie bereits erwähnt wird hierzu in gleicher Weise das Lichtaustrittselement der Beleuchtungsanordnung genutzt, welches für die allgemeine Lichtabgabe vorgesehen ist. If required, the direction of an escape route can be displayed in a coordinated manner, which is done, for example, by the representation of a green luminous point traveling in the direction of the escape route. As already mentioned, the light exit element of the Lighting arrangement used, which is intended for the general light output.
Das Lichtabstrahlelement ist vorzugsweise derart ausgebildet, dass es eine gewisse Vergleichmäßigung der Lichtabgabe bewirkt, was dadurch realisiert werden kann, dass das Lichtabgabeelement lichtstreuendes Material beinhaltet. Bei einer gleichartigen Ansteuerung der Lichtquellen der ersten Gruppe wird hierdurch eine einheitliche, gleichmäßige Lichtabgabe über die gesamte Länge der Leuchte hinweg erzielt. Letztendlich wird also durch die erfindungsgemäße Lösung eine The light-emitting element is preferably designed such that it brings about a certain equalization of the light output, which can be realized by the fact that the light-emitting element contains light-scattering material. With a similar control of the light sources of the first group, a uniform, uniform light output over the entire length of the luminaire is thereby achieved. Ultimately, therefore, by the solution according to the invention a

Application example designed as a recessed light, so it is arranged in an elongated opening within the ceiling 101 and preferably designed such that its light exit plate 5 is flush with the ceiling 101. In the case of a uniform illumination, an elongate light line which preferably extends over the entire length of the space 100 is thereby realized, which has a visually very appealing appearance. The generation of such light lines is already known in principle and takes place with the aid of so-called slotlight lights.
Der Aufbau der erfindungsgemäßen Beleuchtungsanordnung kann näher den The structure of the lighting arrangement according to the invention can be closer to
Darstellungen der Figuren 2 und 3 entnommen werden, wobei Figur 3 eine Representations of Figures 2 and 3 are taken, with Figure 3 a
Schnittdarstellung der Beleuchtungsanordnung 1 zeigt und Figur 2 von der Unterseite her die Anordnung der darin befindlichen Lichtquellen sowie evtl. weiterer Sensoren zeigt. In üblicher Weise weist hierbei die Beleuchtungsanordnung 1 ein Sectional view of the lighting arrangement 1 shows and Figure 2 shows from the bottom the arrangement of the light sources therein and possibly other sensors. In the usual way, in this case, the lighting assembly 1 a
langgestrecktes Trägerelement in Form einer nach unten geöffneten U- förmigen Tragschiene 2 auf. Diese Tragschiene 2 wird innerhalb der Montageöffnung der Decke 101 des zu beleuchtenden Raums 100 angeordnet und dient als zentrales elongated support member in the form of a downwardly open U-shaped mounting rail 2. This support rail 2 is disposed within the mounting opening of the ceiling 101 of the room to be illuminated 100 and serves as a central
Trägerelement für die Beleuchtungsanordnung 1. In ihr sind z.B. in Figur 3 gezeigte Betriebsgeräte 7 zur Stromversorgung der Lichtquellen angeordnet. Ferner verlaufen in Längsrichtung Stromversorgungsleitungen zur Versorgung der Lichtquellen. Mittels nicht näher dargestellter Montageelemente erfolgt hierbei die Befestigung der  Carrier element for the lighting arrangement 1. arranged in Figure 3 operating devices 7 for powering the light sources. Furthermore, power supply lines for supplying the light sources run in the longitudinal direction. By means not shown mounting elements in this case, the attachment of the
Tragschiene 2 in der Deckenöffnung, wobei wie bereits erwähnt die Anordnung derart gewählt ist, dass das an der Unterseite der Tragschiene 2 befindliche längliche Lichtaustrittselement 5 möglichst bündig mit der Deckenunterseite abschließt. Das Lichtaustrittselement 5 selbst ist durch eine oder mehrere längliche Scheiben gebildet, die an der Unterseite der Tragschiene 2 befestigt werden. Innerhalb der Tragschiene 2 sind dann darüber hinaus auch die für die Lichtabgabe verantwortlichen Lichtquellen angeordnet. Support rail 2 in the ceiling opening, wherein, as already mentioned, the arrangement is chosen such that the located on the underside of the support rail 2 elongated light exit element 5 as flush as possible with the ceiling underside. The light exit element 5 itself is formed by one or more elongated discs, which are fastened to the underside of the support rail 2. Within the support rail 2 then also responsible for the light output light sources are arranged.
Im vorliegenden Fall ist zunächst eine erste Gruppe von Lichtquellen 10 vorgesehen, welche - wie in Figur 3 dargestellt - möglichst gleichmäßig verteilt über die gesamte Länge der Beleuchtungsanordnung 1 hinweg angeordnet sind. Diese ersten In the present case, a first group of light sources 10 is first provided, which - as shown in Figure 3 - as evenly distributed over the entire Length of the lighting device 1 are arranged away. These first
Lichtquellen 10 sind für die Allgemeinbeleuchtung verantwortlich und sollen die bereits oben erwähnte Lichtlinie bilden. Es handelt sich dementsprechend um Light sources 10 are responsible for the general lighting and are to form the above-mentioned light line. It is accordingly to
Weißlicht-Lichtquellen, die vorzugsweise durch Weißlicht-LEDs gebildet werden. Wichtig für das Konzept der vorliegenden Erfindung ist hierbei, dass es sich nicht um längliche Lichtquellen handelt, die sich kontinuierlich über die gesamte Länge der Beleuchtungsanordnung 1 hinweg erstrecken. Stattdessen sind im Wesentlichen punktförmige Lichtquellen vorgesehen, die dazwischen liegende freie Bereiche bilden, die - wie nachfolgen noch näher erläutert - zur Anordnung weiterer Komponenten genutzt werden können. Da allerdings trotz allem ein längliches Lichtband möglichst gleichmäßiger Helligkeit erwünscht ist, müssen entsprechende Maßnahmen getroffen werden, dass die Lichtquellen 10 nicht als individuelle Lichtquellen erkennbar sind. Dies kann bspw. dadurch erfolgen, dass den Weißlicht-LEDs 10 entsprechende optische Elemente zugeordnet sind, welche in Längsrichtung der White light sources, which are preferably formed by white light LEDs. It is important for the concept of the present invention that they are not elongate light sources which extend continuously over the entire length of the illumination arrangement 1. Instead, substantially point-shaped light sources are provided which form intermediate free areas, which - as explained in more detail below - can be used to arrange further components. However, since, despite all, an elongated light band of uniform brightness is desired, appropriate measures must be taken that the light sources 10 are not recognizable as individual light sources. This can be done, for example, by assigning corresponding optical elements to the white-light LEDs 10, which in the longitudinal direction of the
Beleuchtungsanordnung 1 eine sehr starke Verteilung bewirken. Darüber hinaus ist das Lichtabstrahlelement 5 selbst derart ausgebildet, dass es für eine entsprechende Vergleichmäßigung der Lichtabgabe sorgt. Hierzu können entsprechende Lighting arrangement 1 cause a very strong distribution. Moreover, the light-emitting element 5 itself is designed such that it ensures a corresponding equalization of the light output. For this purpose, appropriate
lichtstreuende Materialien verwendet werden, aus denen das Lichtabstrahlelement 5 besteht bzw. welche Bestandteil des Lichtabstrahlelements 5 sind. light-scattering materials are used, of which the Lichtabstrahlelement 5 consists or which are part of the Lichtabstrahlelements 5.
Mit Hilfe der bislang beschriebenen Komponenten wird also wiederum zunächst eine klassische Slotlight-Leuchte gebildet, welche die Realisierung von Lichtlinien ermöglicht. Erfindungsgemäß sind nunmehr allerdings innerhalb des Trägerelements 2 zusätzliche Komponenten angeordnet, welche der Erfassung von Sensordaten bspw. für eine automatisierte Steuerung der Beleuchtung oder einer zusätzlichen Lichtabgabe dienen. Dargestellt sind in Figur 2 zum einen ein Sensor 15 sowie zum anderen weitere Lichtquellen 20 einer zweiten Gruppe, die bspw. im Endbereich der With the help of the components described so far, in turn, first a classic slotlight light is formed, which allows the realization of light lines. According to the invention, however, additional components are now arranged within the carrier element 2, which serve for the detection of sensor data, for example, for an automated control of the lighting or an additional light output. FIG. 2 shows, on the one hand, a sensor 15 and, on the other hand, further light sources 20 of a second group which, for example, in the end region of FIG
Beleuchtungsanordnung 1 angeordnet sind. Bei dem Sensor 15 kann es sich bspw. um einen Helligkeitssensor oder um einen Anwesenheitssensor handeln. Die von dem Sensor 15 erfassten Informationen können dann zur automatisierten Steuerung bspw. der Lichtquellen der ersten Gruppe 10 genutzt werden, wobei in üblicher Weise vorgesehen sein kann, dass bei Erkennen der Anwesenheit einer Person die Helligkeit der Lichtquellen 10 angepasst wird bzw. die Lichtquellen 10 überhaupt aktiviert werden. Handelt es sich hingegen um einen Helligkeitssensor, so können die entsprechenden Informationen zum Einstellen der Helligkeit für die Lichtquellen 10 genutzt werden, um unter Nutzung des Umgebungslichts eine optimale Lighting arrangement 1 are arranged. The sensor 15 may, for example, be a brightness sensor or a presence sensor. The information captured by the sensor 15 can then be used for the automated control of, for example, the light sources of the first group 10, it being possible in a customary manner for the brightness of the light sources 10 to be adjusted when the presence of a person is detected or for the light sources 10 be activated at all. If, however, it is a brightness sensor, then the be used to adjust the brightness for the light sources 10 in order to optimize the use of ambient light
energieeffiziente Beleuchtung zu ermöglichen. Die Lichtquellen 20 der zweiten Gruppe dienen im nachfolgend beschriebenen Ausführungsbeispiel der Darstellung eines Fluchtwegs. Es handelt sich zunächst wiederum um im Wesentlichen punktförmige Lichtquellen, welche nunmehr Licht vorzugsweise in grüner Farbe abgeben. Wiederum kommen hierfür bevorzugt LEDs zum Einsatz, welche unabhängig von den Lichtquellen 10 der ersten Gruppe ansteuerbar sind, da die Darstellung eines Fluchtwegs nur im Bedarfsfall erfolgen sollte. to enable energy efficient lighting. The light sources 20 of the second group are used in the embodiment described below, the representation of an escape route. Again, these are essentially point-shaped light sources, which now emit light, preferably in green color. Again, preferably LEDs are used for this purpose, which can be controlled independently of the light sources 10 of the first group, since the representation of an escape route should only be made if necessary.
Wesentlich ist, dass sowohl der Sensor 15 als auch die Lichtquellen 20 der zweiten Gruppe in gleicher Weise innerhalb der Beleuchtungsanordnung 1 angeordnet sind und insbesondere auch in gleicher Weise wie die Lichtquellen der ersten Gruppe 10 dasIt is essential that both the sensor 15 and the light sources 20 of the second group are arranged in the same way within the illumination arrangement 1 and in particular in the same way as the light sources of the first group 10
Lichtabstrahlelement 5 nutzen. D.h., die Lichtquellen 20 der zweiten Gruppe geben im Bedarfsfall auch über das Lichtabstrahlelement 5 Licht ab. Der Sensor 15 hingegen ist dazu ausgebildet, durch das Lichtabstrahlelement 5 hindurch Sensordaten zu erfassen, also bspw. die außerhalb der Leuchte vorliegende Helligkeit zu erfassen oder die Anwesenheit von Personen zu erkennen. Sowohl der Sensor 15 als auch die Use light emitting element 5. In other words, the light sources 20 of the second group emit light, if necessary, also via the light emitting element 5. By contrast, the sensor 15 is designed to detect sensor data through the light-emitting element 5, that is to say, for example, to detect the brightness present outside the luminaire or to detect the presence of persons. Both the sensor 15 and the
Lichtquellen der zweiten Gruppe 20 sind also nicht außerhalb der Light sources of the second group 20 are therefore not outside the
Beleuchtungsanordnung 1 angeordnet und müssen nicht Bestandteil separater Lighting arrangement 1 arranged and need not be part of separate
Elemente sein, welche das Erscheinungsbild der Anordnung insgesamt beeinträchtigen würden. Be elements that would affect the overall appearance of the arrangement.
Die Funktion der Lichtquellen 20 der zweiten Gruppe zur Darstellung eines The function of the light sources 20 of the second group to represent a
Fluchtwegs ist schematisch in Figur 4 erkennbar. Wie bereits erwähnt ist üblicherweise vorgesehen, dass in einem Normalbetrieb mit Hilfe der Lichtquellen 10 der ersten Gruppe eine gleichmäßig helle, sich über die gesamte Länge des Raums 100 hinweg erstreckende Lichtlinie erzeugt wird. Im Falle eines Notzustands hingegen soll dieEscape route is shown schematically in FIG. As already mentioned, it is usually provided that in a normal operation with the aid of the light sources 10 of the first group a uniformly bright light line extending over the entire length of the space 100 is generated. In the case of an emergency condition, however, the
Richtung eines Fluchtwegs dargestellt werden, was gemäß der vorliegenden Erfindung mit Hilfe der Lichtquellen 20 der zweiten Gruppe derart erfolgt, dass ein in Richtung des Fluchtwegs wanderndes grünes Licht dargestellt wird. Wird also davon Direction of an escape route are shown, which is carried out according to the present invention by means of the light sources 20 of the second group such that a wandering in the direction of the escape route green light is displayed. So get away
ausgegangen, dass - wie in Figur 2 dargestellt - drei grüne LEDs 20 vorhanden sind, so werden diese bspw. zeitlich abgestimmt derart angesteuert, dass ein in Pfeilrichtung wandernder grüner Leuchtpunkt 30 an der Lichtaustrittsscheibe 5 der assumed that - as shown in Figure 2 - three green LEDs 20 are present, Thus, for example, these are controlled in a timed manner in such a way that a green luminous point 30 traveling in the direction of the arrow on the light exit disk 5 of FIG
Beleuchtungsanordnung 1 erscheint. Wurde die letzte LED der zweiten Gruppe angesteuert, so wird wieder zurückgesprungen und der wandernde Leuchtpunkt wird wieder von Neuem generiert, sodass eine wellenartige Bewegung eines grünen Lighting arrangement 1 appears. When the last LED of the second group has been triggered, it jumps back and the wandering luminous dot is again generated, so that a wave-like movement of a green
Bereichs erzielt wird, durch den in einfacher und verständlicher Weise die Richtung des Fluchtwegs dargestellt wird. Im Bedarfsfall könnte selbstverständlich auch die Ansteuerung der Lichtquellen 20 der zweiten Gruppe umgekehrt werden, um die Richtung des Fluchtwegs zu invertieren.  The area of the escape route is shown in a simple and understandable way. If necessary, of course, the driving of the light sources 20 of the second group could be reversed to invert the direction of the escape route.
Die erfindungsgemäße Beleuchtungsanordnung kann also neben der allgemeinen Raumbeleuchtung auch zu zusätzlichen Zwecken, insbesondere der Darstellung eines Fluchtwegs genutzt werden, wobei hierfür keine separaten Einheiten montiert werden müssen. Im Normalzustand ergibt sich ausschließlich die gewünschte Darstellung einer Lichtlinie, sodass ein ansprechendes Erscheinungsbild insgesamt erzielt wird. The lighting arrangement according to the invention can therefore be used in addition to the general room lighting for additional purposes, in particular the representation of an escape route, for which no separate units must be mounted. In the normal state, only the desired representation of a light line results, so that a pleasing overall appearance is achieved.
Selbstverständlich müssen die Lichtquellen der ersten Gruppe nicht grundsätzlich einheitlich angesteuert werden. Ist dies aus ästhetischen Gründen gewünscht, besteht selbstverständlich auch die Möglichkeit, die Weißlicht-LEDs zeitlich aufeinander abgestimmt anzusteuern, um bspw. wiederum eine wellenförmige Weißlichtabgabe über die gesamte Länge hinweg zu erzielen. In diesem Fall dient dies allerdings in erster Linie ästhetischen Zwecken, nicht jedoch der Darstellung zusätzlicher Of course, the light sources of the first group do not have to be fundamentally controlled uniformly. If this is desired for aesthetic reasons, it goes without saying that it is also possible to control the white-light LEDs in a time-coordinated manner in order, for example, once again to achieve a wave-like white light output over the entire length. In this case, however, this serves primarily aesthetic purposes, but not the presentation of additional
Informationen oder dergleichen. Insgesamt wird dementsprechend mit Hilfe der vorliegenden Erfindung eine Information or the like. Overall, accordingly, with the aid of the present invention a
Beleuchtungsanordnung geschaffen, welche hinsichtlich ihres äußeren Lighting arrangement created, which in terms of their outer
Erscheinungsbildes höchsten Ansprüchen genügt, allerdings nunmehr dazu genutzt werden kann, zusätzliche Informationen darzustellen oder durch Sensoren Daten für eine automatisierte Beleuchtungssteuerung zu erfassen. Appearance highest demands, but now can be used to represent additional information or to capture data for automated lighting control by sensors.
