Description

Die vorliegende Erfindung betrifft ein Lichtbandsystem für Leuchten gemäß dem Oberbegriff des Anspruchs 1 sowie eine Leuchte, die zur Verwendung bei einem derartigen Lichtbandsystem vorgesehen ist.The present invention relates to a lighting system for luminaires according to the preamble of claim 1 and to a luminaire intended for use in such a lighting system.

Ein gattungsgemäßes Lichtbandsystem ist beispielsweise aus der WO 01/91249 A1 der Anmelderin bekannt. Basiselement eines derartigen Systems ist eine aus Metall, beispielsweise aus Aluminium bestehende Tragschiene, die üblicherweise U-förmig ausgebildet und zur Unterseite hin offen ist. Diese Tragschiene dient als Trägerelement für die Leuchten und stellt die für den Leuchtenbetrieb erforderliche Stromversorgung zur Verfügung. Hierzu verlaufen innerhalb der Tragschiene Leitungen, die neben der Stromversorgung auch eine Übermittlung von Steuerbefehlen für die Leuchten ermöglichen. Einzelne Leuchten können dann an der Tragschiene befestigt und mit den entsprechenden Leitungen verbunden werden, wobei eine Besonderheit des aus der oben genannten WO 01/91249 A1 bekannten Lichtbandsystems darin besteht, dass die Leuchten an einer beliebigen Stelle entlang der Tragschiene montiert werden können, da an jeder Stelle die Möglichkeit zur Kontaktierung der Leitungen besteht.A generic lighting system is, for example, from WO 01/91249 A1 the applicant known. The basic element of such a system is an existing metal, for example aluminum support rail, which is usually U-shaped and open towards the bottom. This mounting rail serves as a carrier element for the lights and provides the required for the lighting operation power supply available. For this purpose, run inside the mounting rail lines that allow in addition to the power supply and a transmission of control commands for the lights. Individual lights can then be attached to the DIN rail and connected to the appropriate lines, with a special feature of the above WO 01/91249 A1 known light strip system is that the lights can be mounted at any point along the mounting rail, as there is the possibility for contacting the lines at any point.

Derartige Lichtbandsysteme eröffnen dementsprechend dem Benutzer die Möglichkeit, Leuchten in nahezu beliebiger Weise zu positionieren. Da ferner auch unterschiedlichste Arten von Leuchten zur Verfügung stehen, weist das System insgesamt eine hohe Flexibilität auf, weshalb es für die verschiedensten Anwendungsbereiche genutzt werden kann.Accordingly, such lighting systems open up the possibility for the user to position luminaires in almost any desired manner. Furthermore, since a wide variety of types of lights are available, the system has a high overall flexibility, which is why it can be used for a variety of applications.

Die bei derartigen Lichtbandsystemen eingesetzten Leuchten oder Leuchtenmodule, die auch als Lichtbalken bezeichnet werden, können beispielsweise Leuchtstofflampen als Lichtquellen aufweisen. Die hierbei oftmals zum Einsatz kommenden sog. elektronischen Vorschaltgeräte (EVG) zum Betreiben der Leuchtstofflampen sind dann an der Oberseite des Leuchtenmoduls angeordnet, sodass sie nach Montage im Inneren der Tragschiene angeordnet sind. Die Lichtquellen selbst hingegen befinden sich an der Unterseite, wobei dann gegebenenfalls weitere optische Elemente wie transparente Abdeckungen oder Reflektoren an dem Leuchtenmodul selbst oder an der Tragschiene befestigt werden können, um die Lichtabgabe in gewünschter Weise zu beeinflussen.The luminaires or luminaire modules used in such lighting systems, which are also referred to as light bars, may, for example, comprise fluorescent lamps as light sources. The electronic ballasts (ECG) for operating the fluorescent lamps, which are often used in this case, are then arranged on the upper side of the luminaire module, so that they are arranged in the interior of the mounting rail after mounting. The light sources themselves, on the other hand, are located on the underside, in which case optionally further optical elements, such as transparent covers or reflectors, can be fastened to the luminaire module itself or to the mounting rail in order to influence the light output in the desired manner.

Der vorliegenden Erfindung liegt die Aufgabe zu Grunde, die Möglichkeiten zur Nutzung derartiger Lichtbandsysteme zu erweitern.The present invention is based on the object to expand the possibilities for using such lighting systems.

Die Aufgabe wird durch ein Lichtbandsystem mit den Merkmalen des Anspruchs 1 sowie durch eine Leuchte zur Nutzung bei einem derartigen Lichtbandsystem entsprechend dem Anspruch 10 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der abhängigen Ansprüche.The object is achieved by a lighting system with the features of claim 1 and by a luminaire for use in such a lighting system according to claim 10. Advantageous developments of the invention are the subject of the dependent claims.

Die erfindungsgemäße Lösung beruht zunächst auf der Idee, neuartige Leuchten zu verwenden, bei denen als Lichtquellen LEDs genutzt werden. Im Gegensatz zu klassischen LED-Platinen allerdings, bei denen die Lichtquellen auf der Oberfläche der Platinen angeordnet sind, ist nunmehr vorgesehen, dass die LEDs in das Leuchtenmodul integriert sind. Hierzu weist ein Trägerelement der Leuchte, welches zur Befestigung an der Tragschiene vorgesehen ist, mehrere Lichtabgabe-Öffnungen auf. In diesen Öffnungen sind dann jeweils zumindest eine LED oder ein der LED zugeordnetes Lichtlenkelement angeordnet.The solution according to the invention is based initially on the idea of using novel luminaires in which LEDs are used as light sources. In contrast to conventional LED boards, however, in which the light sources are arranged on the surface of the boards, it is now provided that the LEDs are integrated into the lamp module. For this purpose, a support element of the luminaire, which is provided for attachment to the mounting rail, a plurality of light-emitting openings. In each case, at least one LED or a light-directing element assigned to the LED are arranged in these openings.

Erfindungsgemäß wird dementsprechend ein Lichtbandsystem für Leuchten vorgeschlagen, mit mindestens einer U-förmigen Tragschiene sowie innerhalb der Tragschiene in Längsrichtung verlaufenden Stromversorgungs- und/oder Signalleitungen zur Stromversorgung sowie gegebenenfalls zur Übertragung von Steuerbefehlen für die Leuchten und zumindest einer an die Tragschiene anschließbaren Leuchte, welche ein an der Tragschiene anzuordnendes Trägerelement zur Haltung von Lichtquellen aufweist, wobei erfindungsgemäß vorgesehen ist, dass die Lichtquellen durch LEDs gebildet sind, und wobei das Trägerelement mehrere Lichtabgabe-Öffnungen aufweist, in denen jeweils zumindest eine LED oder ein der LED zugeordnetes Lichtlenkelement angeordnet sind.According to the invention, a lighting system for luminaires is proposed accordingly, with at least one U-shaped mounting rail and within the mounting rail in the longitudinal direction extending power supply and / or signal lines for power and optionally for transmitting control commands for the lights and at least one connectable to the DIN rail light, which a to be arranged on the support rail carrier element for holding light sources, which is provided according to the invention that the light sources are formed by LEDs, and wherein the carrier element has a plurality of light-emitting openings, in each of which at least one LED or the LED associated light-guiding element are arranged.

Ferner wird erfindungsgemäß eine Leuchte zur Verwendung bei einem derartigen Lichtbandsystem vorgeschlagen, wobei die Leuchte ein an der Tragschiene des Lichtbandsystems anzuordnendes Trägerelement zur Haltung von Lichtquellen aufweist und erfindungsgemäß die Lichtquellen durch LEDs gebildet sind, wobei das Trägerelement mehrere Lichtabgabe-Öffnungen aufweist, in denen jeweils zumindest eine LED oder ein der LED zugeordnetes Lichtlenkelement angeordnet sind.Further, the invention proposes a lamp for use in such a lighting system, wherein the lamp has a to be arranged on the support rail of the light band system support member for holding light sources and according to the invention the light sources are formed by LEDs, wherein the support member has a plurality of light-emitting openings, in each case at least one LED or a light-guiding element associated with the LED are arranged.

Die erfindungsgemäße integrierte Anordnung der LED-Lichtquellen bei den Leuchten verleiht diesen zunächst ein besseres Aussehen. Ein weiterer Vorteil dieser Lösung besteht ferner darin, das nunmehr die Lichtquellen geschützt, beispielsweise innerhalb des Aufnahmeraums der Tragschiene angeordnet sind. Dies ist insofern relevant, als nunmehr nicht mehr die Gefahr besteht, dass die Lichtquellen bei einer Montage bzw. Demontage der Leuchte an der Tragschiene versehentlich berührt werden. Dementsprechend besteht keine Verletzungsgefahr, obwohl üblicherweise die Stromversorgungsleitungen, die innerhalb der Tragschiene eines Lichtbandsystems verlaufen, dauerhaft unter Strom gesetzt sind. Dementsprechend ist eine Montage oder Demontage der Leuchtenmodule problemlos möglich.The inventive integrated arrangement of the LED light sources in the lights initially gives them a better look. A further advantage of this solution is also that now protected the light sources, for example, are arranged within the receiving space of the support rail. This is relevant insofar as now no longer the danger that the light sources are accidentally touched when mounting or dismounting the lamp to the mounting rail. Accordingly, there is no risk of injury, although usually the Power supply lines that run within the trunking of a lighting system, are permanently energized. Accordingly, a mounting or dismounting of the lamp modules is easily possible.

Gemäß einem ersten Ausführungsbeispiel der vorliegenden Erfindung können die LEDs beispielsweise an der im Innenraum der Tragschiene zugewandten Seite des Trägerelements der Leuchte angeordnet sein, wobei sie dann zumindest teilweise in die Lichtabgabe-Öffnung des Trägerelements ragen. In diesem Fall kann beispielsweise eine transparente Abdeckung an der Unterseite des Leuchtmoduls angeordnet werden. Alternativ hierzu wäre es allerdings auch denkbar, die LEDs in einem Abstand hinter den Lichtabgabe-Öffnungen anzuordnen. In diesem Fall wäre es beispielsweise denkbar, die Lichtlenkelemente durch Linsen zu bilden, welche dann bündig innerhalb der Lichtabgabeöffnungen angeordnet sind. Anstelle der Linsen könnten als Lichtlenkelemente allerdings auch Reflektoren verwendet werden.According to a first exemplary embodiment of the present invention, the LEDs can be arranged, for example, on the side of the carrier element of the luminaire facing in the interior of the carrier rail, in which case they project at least partially into the light-emitting opening of the carrier element. In this case, for example, a transparent cover can be arranged on the underside of the lighting module. Alternatively, however, it would also be conceivable to arrange the LEDs at a distance behind the light-emitting openings. In this case, it would be conceivable, for example, to form the light-guiding elements by means of lenses, which are then arranged flush within the light-emitting openings. Instead of the lenses, however, reflectors could also be used as light-guiding elements.

Vorzugsweise sind an dem Trägerelement einer Leuchte mehrere LEDs in Längsrichtung hintereinander angeordnet. Durch die Verwendung verschiedenfarbiger LEDs kann dann durch eine entsprechende Ansteuerung bzw. Regelung der Intensität der einzelnen Farben Mischlicht eines beliebigen Farbtons erzielt werden, sodass letztendlich die Möglichkeit besteht, unterschiedlichste Beleuchtungseffekte zu erzielen.Preferably, a plurality of LEDs are arranged one behind the other in the longitudinal direction on the support element of a lamp. Through the use of differently colored LEDs mixed light of any hue can then be achieved by a corresponding control or regulation of the intensity of the individual colors, so that ultimately there is the possibility to achieve a variety of lighting effects.

Anhand der Figuren 1 und 2 soll zunächst der grundsätzliche Aufbau eines Lichtbandsystems erläutert werden. Die Figuren zeigen hierbei ein System entsprechend der WO 01/91249 A1 , bei dem auf Grund einer besonders vorteilhaften Ausgestaltung eine freie Kontaktierung der Stromversorgungsleitungen über die gesamte Länge der Tragschiene hinweg möglich ist. Die vorliegende Erfindung ist allerdings keinesfalls auf ein derartiges Lichtbandsystem beschränkt. Stattdessen können die nachfolgend noch näher erläuterten erfindungsgemäßen Leuchtenmodule auch bei Lichtbandsystemen zum Einsatz kommen, bei denen lediglich an bestimmten vorgesehenen Stellen eine Anordnung der Leuchten möglich ist.Based on Figures 1 and 2 First, the basic structure of a lighting system will be explained. The figures show a system according to the WO 01/91249 A1 in which due to a particularly advantageous embodiment, a free contacting of the power supply lines over the entire length of the mounting rail away is possible. However, the present invention is by no means limited to such a light band system. Instead, the lighting modules according to the invention explained in more detail below can also be used in light band systems in which an arrangement of the luminaires is possible only at certain intended locations.

Basiselement des Lichtbandsystems ist eine aus Metall, beispielsweise aus Aluminium bestehende U- oder V-förmige Tragschiene 1, welche als Trägerelement für die verschiedenen Leuchten dient und die zum Betrieb der Leuchten erforderliche Stromversorgung bereitstellt. Die Tragschiene 1 wird mit Hilfe von nicht näher dargestellten Befestigungselementen an einem Träger, zum Beispiel einer Raumdecke oder einer Raumwand befestigt, wobei die offene Seite der Tragschiene 1 nach unten gerichtet ist. Die Abdeckung der offenen Unterseite der Tragschiene 1 erfolgt in denjenigen Bereichen, in denen keine Leuchten vorgesehen sind, durch eine Abdeckschiene 5. Diese ist in ihren Randbereichen derart ausgestaltet, dass sie werkzeuglos auf die Unterseite der Tragschiene 1 aufgeschnappt werden kann. Diejenigen Bereiche der Tragschiene 1, die also nicht durch Leuchtenmodule geschlossen werden, könne auf diese Weise durch die Abdeckschiene 5 abgedeckt werden, sodass letztendlich die Tragschiene 1 über die gesamte Läng hinweg zur Unterseite hin geschlossen ist.Basic element of the lighting system is a metal, for example made of aluminum U-shaped or V-shaped mounting rail 1, which serves as a support element for the various lights and provides the required for the operation of the lights power supply. The mounting rail 1 is fastened by means of fasteners, not shown, to a support, for example a ceiling or a room wall, wherein the open side of the support rail 1 is directed downward. The cover of the open underside of the mounting rail 1 takes place in those areas where no lights are provided by a cover rail 5. This is designed in their edge areas such that they can be snapped onto the underside of the mounting rail 1 without tools. Those areas of the mounting rail 1, which are therefore not closed by lamp modules, can be covered in this way by the cover rail 5, so that ultimately the support rail 1 is closed over the entire length away to the bottom.

Der Innenraum der Tragschiene 1 dient zur Aufnahme sogenannter Stromleitprofile, die durch mehrere aus Kunststoff bestehende und zusammengesetzte Drahthalterungselemente 3 gebildet werden, die jeweils an den Seitenwänden 2 der Tragschiene angeordnet sind. Die Drahthalterungselemente 3 weisen mehrere übereinander angeordnete Nuten auf, in denen Drähte 4 verlaufen. Diese Drähte 4 werden sowohl zur Stromversorgung der Leuchten als auch zur Übermittlung von - vorzugsweise digitalen - Steuersignalen verwendet. Die Lagerung der Drähte 4 in den Nuten der Drahthalterungselemente 3 gewährt die erforderliche Sicherheit gegen eine versehentliche Berührung der stromführenden Leitungen, so dass entsprechende Unfälle ausgeschlossen werden. Durch eine Kontaktierung der entsprechenden Drähte 4 kann der angeschlossenen Leuchte dann eine gewünschte Funktion zugewiesen werden, beispielsweise kann die Leuchte als Notlichtleuchte verwendet werden. Zur genaueren Ausführung der Drahthalterungselemente 3 bzw. des gesamten Lichtbandsystems wird auf die zuvor genannte WO 01/91249 A1 verwiesen, wobei nochmals darauf hingewiesen werden soll, dass das Lichtbandsystem hinsichtlich der Ausgestaltung der Tragschiene und der Stromleitungen auch anders ausgestaltet sein könnte. Beispielsweise könnte auch vorgesehen sein, dass die Leitungen an der Decke der Tragschiene verlaufen.The interior of the mounting rail 1 serves to accommodate so-called Stromleitprofile, which are formed by a plurality of plastic existing and composed wire support members 3, which are respectively arranged on the side walls 2 of the support rail. The wire holder elements 3 have a plurality of superimposed grooves in which wires 4 extend. These wires 4 are used both for powering the lights and for the transmission of - preferably digital - control signals. The storage of the wires 4 in the grooves of the wire holder elements 3 provides the required security against accidental contact with the live lines, so that corresponding accidents are excluded. By contacting the corresponding wires 4, the connected light can then be assigned a desired function, for example, the light can be used as an emergency light. For more accurate execution of the wire support members 3 and the entire lighting system is on the aforementioned WO 01/91249 A1 referenced, which should again be noted that the lighting system with respect to the design of the support rail and the power lines also be designed differently could. For example, it could also be provided that the lines run on the ceiling of the mounting rail.

Die Figuren 3 bis 7 zeigen nunmehr Ansichten eines ersten Ausführungsbeispiels einer erfindungsgemäßen Leuchte 10, die bei dem Lichtbandsystem zum Einsatz kommen soll. Die Leuchte 10 weist ein längliches Trägerelement 11 auf, das als Träger für die verschiedenen Komponenten der Leuchte 10 dient und hinsichtlich seiner Form in etwa der Abdeckschiene 5 entspricht. Wie insbesondere der Schnittdarstellung der Figur 4 entnommen werden kann, sind also wiederum die Seitenbereiche 12 des Trägerelements 11 derart geformt, dass dieses auf die Unterseite der Tragschiene 1 aufgeschnappt werden kann. Eine mechanische Befestigung der Leuchte 10 an der Tragschiene 1 erfolgt dann zusätzlich mit Hilfe zweier Kontaktierungselemente 15, welche drehbar an der Oberseite des Trägerelements 11 angeordnet sind. Nach dem Einführen in den Innenraum der Tragschiene 1 können die Kontaktierungselemente 15 verdreht werden, wobei an den Kontaktierungselementen 15 ausgebildete Verriegelungselemente dann in entsprechende Ausnehmungen der Tragschiene 1 eingreifen, so dass eine Verankerung erzielt wird. Ferner weisen die Kontaktierungselemente 15 mehrere seitliche Anschlusskontakte auf, welche durch das Verdrehen in die Nuten der Drahthalterungselemente 3 eingreifen und gegen die Drähte 4 zur Anlage kommen. Diese Kontaktierungselemente können insbesondere höhenverstellbar ausgebildet sein, wobei hierzu wiederum auf den bereits oberen genannten Stand der Technik verwiesen wird. Eine Betätigung der Kontaktierungselemente 15 erfolgt mit Hilfe von an der Unterseite vorgesehenen Drehknebeln 16, welche anschließend versenkt werden können, sodass sie nicht über die Unterseite des Trägerelements 11 hervorstehen.The FIGS. 3 to 7 Now show views of a first embodiment of a lamp 10 according to the invention, which is to be used in the lighting system. The luminaire 10 has an elongate carrier element 11 which serves as a carrier for the various components of the luminaire 10 and corresponds approximately to the cover rail 5 in terms of its shape. As in particular the sectional view of FIG. 4 can be removed, in turn, the side portions 12 of the support member 11 are shaped such that it can be snapped onto the underside of the support rail 1. A mechanical attachment of the lamp 10 to the mounting rail 1 is then additionally by means of two contacting elements 15 which are rotatably arranged on the upper side of the support member 11. After insertion into the interior of the mounting rail 1, the contacting elements 15 can be rotated, wherein formed on the contacting elements 15 locking elements then engage in corresponding recesses of the mounting rail 1, so that an anchorage is achieved. Furthermore, the contacting elements 15 have a plurality of lateral connection contacts, which engage in the grooves of the wire holder elements 3 by twisting and come into contact with the wires 4. These contacting elements may in particular be designed to be height-adjustable, in which case reference is again made to the already mentioned prior art. An actuation of the contacting elements 15 takes place with the aid of provided on the bottom rotary knobs 16, which can then be sunk so that they do not protrude beyond the bottom of the support member 11.

An der Oberseite des Trägerelements 11 sind ferner Betriebsgeräte 17 angeordnet, welche der Ansteuerung der verschiedenen Lichtquellen der Leuchte 10 dienen. Die Betriebsgeräte können insbesondere derart ausgestaltet sein, dass sie eine Ansteuerung der Lichtquellen in Abhängigkeit von über die Signalleitungen des Lichtbandsystems erhaltenen Steuerbefehlen vornehmen. Auf diesem Wege wird die Möglichkeit eröffnet, die Leuchten des gesamten Lichtbandsystems von einer Zentrale aus anzusteuern.At the top of the support member 11 further operating devices 17 are arranged, which serve to control the various light sources of the lamp 10. The operating devices may in particular be designed such that they make a control of the light sources in response to control commands received via the signal lines of the lighting system. In this way, the possibility opens, the lights of the entire lighting system from a control center to control.

Gemäß der vorliegenden Erfindung ist nunmehr vorgesehen, dass als Lichtquellen der Leuchten 10 LEDs zum Einsatz kommen. Diese sind bei dem dargestellten Ausführungsbeispiel an einem C-förmigen Tragteil 18 angeordnet, welches an der Oberseite des Trägerelements 11 montiert ist. Dabei ist vorgesehen, dass über die gesamte Länge der Leuchte 10 hinweg eine Vielzahl von LEDs 20 zum Einsatz kommen, wobei die Lichtabgabe jeweils über den LEDs 20 zugeordnete Lichtabgabe-Öffnungen 21 erfolgt, die in das Trägerelement 11 eingebracht, beispielsweise eingestanzt sind. Vorzugsweise ist hierbei jeder einzelnen LED 20 eine entsprechende Lichtabgabe-Öffnung 21 zugeordnet, wobei gemäß der Darstellung in Figur 4 die LEDs 20 in einem geringen Abstand an der Rückseite der Lichtabgabe-Öffnungen 21 angeordnet ist. Das Licht jeder LED 20 wird dann mit Hilfe eines zugeordneten Lichtlenkelements 22 in einen gewünschten Winkelbereich abgegeben. Beim dargestellten Ausführungsbeispiel kommen hierbei als Lichtlenkelemente Linsen 22 zum Einsatz, welche bündig in die Lichtabgabe-Öffnungen 21 des Trägerelements 11 integriert sind bzw. lediglich geringfügig hervorstehen, wie die Darstellung von Figur 4 zeigt.According to the present invention, it is now provided that 10 LEDs are used as the light sources of the luminaires. These are arranged in the illustrated embodiment on a C-shaped support member 18 which is mounted on the top of the support member 11. It is provided that across the entire length of the lamp 10 away a plurality of LEDs 20 are used come, wherein the light output in each case via the LEDs 20 associated light-emitting openings 21, which are introduced into the support member 11, for example, are punched. Preferably, each individual LED 20 is associated with a corresponding light-emitting opening 21, wherein, as shown in FIG FIG. 4 the LEDs 20 are arranged at a small distance at the rear of the light-emitting openings 21. The light of each LED 20 is then emitted by means of an associated light-guiding element 22 in a desired angular range. In the illustrated embodiment, lenses 22 are used here as light-guiding elements, which are integrated flush in the light-emitting openings 21 of the carrier element 11 or protrude only slightly, such as the representation of FIG FIG. 4 shows.

Durch die oben beschrieben Anordnung wird letztendlich eine Leuchte geschaffen, deren Unterseite nahezu eben ist. Hierdurch ergeben sich im Vergleich zur klassischen Leuchten, bei denen die Lichtquellen grundsätzlich an der Unterseite des Trägerelements angeordnet waren, neue Gestaltungsmöglichkeiten. Ferner wird durch den Einsatz der LEDs - sofern gewünscht - die Möglichkeit eröffnet, Licht in unterschiedlichen Farben abzugeben, sodass neuartige lichttechnische Effekte erzielt werden können. Alternativ zu den dargestellten Linsen können als Lichtlenkelemente auch kleine Reflektoren eingesetzt werden.The arrangement described above ultimately creates a luminaire whose underside is almost flat. This results in comparison to the classic lights, in which the light sources were basically arranged on the underside of the support element, new design options. Furthermore, the use of LEDs - if desired - opens up the possibility of emitting light in different colors, so that novel lighting technology effects can be achieved. As an alternative to the illustrated lenses, small reflectors can also be used as light-guiding elements.

Ein weiterer Vorteil der erfindungsgemäßen Ausgestaltung ist, dass auf Grund der integrierten Anordnung der Lichtquellen die Unterseite der Leuchte 10 frei von elektrischen Leitungen und dergleichen ist. Ein Lampenwechsel, bei dem die Drehknebel 16 betätigt werden müssen, ist dementsprechend nicht mit der Gefahr verbunden, dass versehentlich stromführende Leitungen berührt werden. Dies ist insofern von Bedeutung, als auch während des Lampenwechsels in der Regel die stromführenden Drähte 4 innerhalb der Tragschiene 1 nach wie vor unter Strom stehen.Another advantage of the embodiment of the invention is that due to the integrated arrangement of the light sources, the bottom of the lamp 10 is free of electrical wiring and the like. A lamp replacement, in which the rotary knob 16 must be operated, is therefore not associated with the risk that inadvertently live cables are touched. This is important insofar as the current-carrying wires 4 within the support rail 1 are still under current during lamp replacement as a rule.

Bei dem in den Figuren 4 bis 7 dargestellten Ausführungsbeispiel waren die LEDs 20 beabstandet zu den Lichtabgabe-Öffnungen 21 positioniert, so dass sie nach Montage der Leuchte 10 an der Tragschiene 1 innerhalb des Aufnahmeraums der Schiene 1 angeordnet waren. Entsprechend der Darstellung in Figur 8 bestünde allerdings auch die Möglichkeit, eine die LED 20 tragende Platine 25 unmittelbar an der Rückseite des Trägerelements 11 anzuordnen. Die LED 20 ragt in diesem Fall durch die Lichtabgabe-Öffnung 21 des Trägerelements 11 hindurch. Auch in diesem Fall besteht nicht die Gefahr, dass versehentlich stromführende Leitungen berührt werden, da die LED 20 die Lichtabgabe-Öffnung 21 ausfüllt. Es ist in diesem Fall ferner vorzugsweise eine transparente Abdeckung 30 vorgesehen, welche länglich ausgestaltet ist und auf die Unterseite des Trägerelements 11 aufgeschnappt werden kann. Diese Abdeckung 33 kann hierbei in dem Bereich, der - in Lichtabstrahlrichtung - der LED 20 vorgeordnet ist, eine linsenförmige Verdickung 31 aufweisen. Über diese wird wiederum die Lichtabstrahlcharakteristik beeinflusst, so dass auch hier das Licht der LEDs 20 in einen gewünschten Bereich abgestrahlt werden kann. Die lösbare Anordnung der Abdeckung 33 bringt ferner den Vorteil mit sich, dass nunmehr unterschiedlich ausgestaltete Abdeckungen an dem Trägerelement 11 befestigt werden können. Beispielsweise wäre es denkbar, verschiedene Abdeckungen zur Verfügung zu stellen, die sich hinsichtlich der Ausgestaltung der linsenförmigen Verdickung unterscheiden, um die Lichtabstrahlcharakteristik der Leuchte 10 in gewünschter Weise zu beeinflussen. Auch die Verwendung von Abdeckungen mit einer strukturierten, beispielsweise linsenförmigen Oberfläche wäre möglich.In the in the FIGS. 4 to 7 In the embodiment shown, the LEDs 20 were positioned at a distance from the light-emitting openings 21 so that they were arranged after mounting the lamp 10 on the mounting rail 1 within the receiving space of the rail 1. As shown in FIG. 8 However, it would also be possible to arrange a PCB 20 carrying the LED 20 directly to the back of the support member 11. In this case, the LED 20 protrudes through the light-emitting opening 21 of the carrier element 11. Also in this case, there is no risk that accidentally live lines are touched, since the LED 20 fills the light-emitting opening 21. In this case, it is further preferable to provide a transparent cover 30 which is elongate is configured and can be snapped onto the underside of the support member 11. In this case, this cover 33 can have a lenticular thickening 31 in the region which is arranged upstream of the LED 20 in the light emission direction. In turn, the light emission characteristic is influenced by these, so that here too the light of the LEDs 20 can be radiated into a desired region. The detachable arrangement of the cover 33 also brings the advantage that now differently designed covers can be attached to the support member 11. For example, it would be conceivable to provide different covers which differ with respect to the design of the lenticular thickening in order to influence the light emission characteristic of the luminaire 10 in the desired manner. The use of covers with a structured, for example lenticular surface would also be possible.

Letztendlich wird also durch die vorliegende Erfindung ein neuartiges Leuchtenmodul zur Verwendung bei Lichtbandsystemen geschaffen, welches auf Grund der integrierten Anordnung der LED-Lichtquellen ansprechende Lichteffekte ermöglicht und auf Grund der flachen Ausgestaltung die Einsatzmöglichkeiten für Lichtbandsysteme zusätzlich erweitert.Ultimately, therefore, the present invention provides a novel lamp module for use in lighting systems, which allows due to the integrated arrangement of LED light sources appealing lighting effects and due to the flat design, the potential applications for lighting systems additionally expanded.
