[0003] Light strip with position-optimized components

[0004] The invention relates to a system for realizing a luminaire which is elongated in a longitudinal direction, as well as to a luminaire realized by means of such a system, and to a method for realizing an arrangement of luminaire components or a luminaire.

[0005] Generic systems are designed to produce a generic luminaire which is elongated in a longitudinal direction and usually comprises a plurality of longitudinally elongated support rails. The support rails are typically used to fix the luminaire to a building structure, for example to a ceiling. The support rails represent a type of basic framework for the luminaire and are designed to accommodate supply lines and preferably to accommodate mounting bodies to which lamps or other electrical functional elements are attached. Thus, an infrastructure for the luminaire is provided via the support rails. Electrical functional elements of the luminaire are usually attached to the mounting bodies, for example lamps, in particular comprising circuit boards with LEDs, radio modules, electrical cables and / or operating devices.When installing the luminaire, the respective support rail is usually first fastened to the building structure and then the mounting body, which is equipped with at least one of the aforementioned electrical functional elements of the luminaire, is fixed to the support rail, so that the support rail and mounting body enclose an interior space in which essential elements of the luminaire are arranged, for example circuit boards, operating devices, contact devices, etc. Typically, the support rail and mounting body are each elongated in a longitudinal direction, preferably the longitudinal extent is at least five times the extent perpendicular to the longitudinal direction. The support rail usually has a U-shaped cross-section perpendicular to the longitudinal direction, which extends in a vertical direction and in a transverse direction and is open at one vertical end and which is formed by a support rail base and two support rail side walls.The support rail side walls therefore run vertically away from the support rail base, and the support rail base connects the transversely spaced support rail side walls, and opposite the support rail base the support rail has an open side. Depending on requirements the support rail base and support rail side walls can have contours or cutouts or passages or indentations. The support rail base and the support rail side walls usually together form a support rail interior that is at least partially enclosed by the support rail side walls and the support rail base. The support rail interior is therefore defined by the support rail. Usually all support rails in a system have the features described here.A generic system often has at least a first and a second support rail which are connected to one another at their mutually facing longitudinal ends to form the luminaire. They usually form a common interior space which extends elongated between the support rail side walls of both support rails and the support rail base of both support rails along the longitudinal extent of both elongated support rails. The two support rails are usually fixed to one another by means of a coupling which has a U-shaped cross-section formed by a coupling base and two coupling side walls. The coupling side walls thus run vertically away from the coupling base, and the support rail base connects the coupling side walls which are spaced apart transversely from one another. The U-shaped cross section of the coupling is preferably open at its end opposite the coupling base.Typically, each of the support rails has a substantially constant cross-section perpendicular to the longitudinal direction, wherein the cross-section is preferably identical except for recesses, which are designed in particular as embossing or feedthroughs, and / or punchings in the support rail base and / or support rail side walls. Frequently, the cross-section of all support rails is substantially the same. Typically, the support rails are fixed relative to one another by the coupling perpendicular to the longitudinal direction and in particular also in the longitudinal direction by means of the coupling. In an operating state of the system, in which the first and second support rails are fixed to one another, the coupling is usually arranged in the two support rails in such a way that the coupling base runs along both support rail bases and each of the coupling side walls rests against a respective one of the support rail side walls assigned to it.

[0006] Usually, the support rail is

[0007] The support rail base is attached to the building structure.

[0008] The mounting body is usually arranged on the open side of the support rail, so that the mounting body vertically delimits the support rail interior defined by the support rail, and the mounting body, together with the support rail on which it is arranged, encloses an interior space perpendicular to the longitudinal direction. At least in some longitudinal sections, the enclosure of the interior space formed by the support rail and mounting body can be interrupted, for example to allow access to the interior space, for example for air supply. The interior space is preferably continuously enclosed over at least 80%, in particular at least 90% of its longitudinal extent, in particular over its longitudinal extent.The mounting body often has a cross-section perpendicular to the longitudinal direction, which comprises a mounting body base extending in the transverse direction and mounting body side walls extending vertically away from the mounting body base on the two transverse sides of the mounting base. The support rail and mounting body are usually manufactured separately. The support rail and / or mounting body are generally preferably and usually each manufactured from a sheet metal by forming. In an operating state of the system, in which the system is used as intended, the mounting body is usually held by a retaining spring on support rail retaining anchors of the support rail. A wide variety of possibilities for implementing such a retaining spring are known in the prior art.The retaining spring is usually firmly connected to the mounting body and has retaining projections which can be elastically deflected in the transverse direction, wherein the transverse direction, with reference to the mounting body, relates to the operating state of the system. The mounting rail retaining anchors are preferably designed as projections. To realize a generic luminaire, supply lines are usually provided which are arranged in the interior of the mounting rails and are supplied by the lamps and / or other electrical functional elements which are arranged on the mounting bodies of the luminaire. A generic system generally preferably has a current conducting rail which is usually made of plastic, in particular by means of an extrusion process or injection molding process, and which is also elongated in the longitudinal direction, i.e. has an elongated longitudinal extent between both of its longitudinal ends.The current conducting rail is usually arranged on an inner side of the support rail facing the interior and is fixed to the support rail, in particular to the support rail base and / or to at least one of the support rail side walls. The current conducting rail extends over a substantial proportion of the length of the support rail, in particular over at least 80% of the longitudinal extent of the support rail. The current conducting rail usually has a plurality of channels arranged next to one another along a row direction, which channels are open to an access side that is accessible from the interior. In the operating state, the current conducting rail is fixed to the support rail in such a way that the row direction runs perpendicular to the longitudinal direction. In one embodiment, the row direction runs parallel to the transverse direction in the operating state of the system.The channels preferably extend continuously over the entire length of the current conducting rail. In particular, the transverse direction, the longitudinal direction and the vertical direction run perpendicular to one another. In at least some of the channels, at least one conducting wire is arranged in each case, in particular exactly one conducting wire or exactly two conducting wires which are held at a distance from one another in the respective channel, and at least one longitudinal end of the current conducting rail, the conducting wires are usually connected to an external voltage source via which electrical energy, in particular at least partially in the form of electrical signals, can be applied to the conducting wires. The conducting wires can thus serve as supply lines in the support rails.For this purpose, an electrical connector is usually arranged at the longitudinal end, which is electrically connected to the conducting wires and via which the conducting wires are supplied with electrical energy, and / or a feed device is provided, which is arranged on an access side of the current conducting rail pointing along the vertical direction or along the transverse direction, is connected to the conducting wires and which itself is or can be supplied with energy from an external energy source. Such a feed device often has a fastening device and feed contacts on a contact side, which are arranged in an operating state or, in the case of a realized luminaire, for feeding energy into the conducting wires in at least some of the channels of the current conducting rail and contact the conducting wire arranged therein.The feed contacts are usually arranged next to one another in the same direction of arrangement as the line wires and the contacts of a contact device (explained in more detail elsewhere) are arranged next to one another. In most cases, an electrical connector is provided at each longitudinal end of the current conducting rail. The electrical connectors can, for example, be designed as connectors that correspond to one another, for example a first one as a plug and a second one as a socket. If at least one connector is provided at at least one longitudinal end of the current conducting rail, adjacent current conducting rails in the longitudinal direction can be electrically connected to one another so that the line wires can form through-wiring.

[0009] In conventional embodiments, the system also frequently comprises a contact device via which electrical contact is established between the conductor wires assigned to the current conducting rail and at least one electrical functional element of the mounting body. The contact device is typically fixed to the mounting body and ensures an electrical connection of the at least one electrical functional element when the mounting body is held in the operating state of the system or in its intended position on the support rail in which the luminaire is implemented. The contact device is designed to engage in the channels from the access side of the support rail in order to contact the conductor wires.For this purpose, the contact device has a plurality of contact units arranged side by side in an arrangement direction, wherein, in the operating state of the system, each of the contact units rests electrically conductively on one of the conductor wires arranged in the channels of the current conducting rail. In the operating state, the arrangement direction, which is defined with reference to the contact device, is arranged parallel to the alignment direction, which is defined with reference to the current conducting rail.To contact the conductor wires, the contact device is arranged with its contact side on the access side of the conductor rail. The contact units for contacting the conductor wires are inserted into the channels along a plug-in direction defined for the contact device, resulting from the arrangement of the contact units. The plug-in direction is usually perpendicular to the arrangement direction and, accordingly, to achieve the operating state, perpendicular to the alignment direction. The contact units each have a contact with which they make electrically conductive contact with one of the conductor wires in the operating state.

[0010] Generic systems are used in a wide range of applications, for example in warehouses, production halls, supermarkets or open-plan offices, whereby luminaires with a plurality of support rails and mounting bodies are used. The basic principle of luminaires manufactured using a generic system is that the support rails form the electrical and mechanical infrastructure of these luminaires, whereas the mounting bodies are attached to the support rails and have the electrical functional elements that are required in the respective area of ​​application. Of course, at least some of the electrical functional elements are usually designed as lighting modules with light sources, in particular comprising LED boards.For example, alternatively or additionally, further electrical functional elements may be provided on the respective mounting body, such as a presence sensor (e.g., an infrared sensor), a camera, a radio module, etc. The electrical functional elements are usually fixed to the mounting body.

[0011] In typical applications, generic systems are used in such a way that a plurality of luminaire components, each of which comprises a support rail designed as explained, are arranged one behind the other in the longitudinal direction and connected to one another. Further components of the respective luminaire component can be arranged on or in the support rails of the luminaire components. For example, lamps and supply lines can be fastened to the support rails, for example directly to the support rails, for example by providing a mounting body designed as explained above and / or a current conducting rail designed as explained above. For example, each luminaire component can each comprise a support rail, a current conducting rail and a mounting body and in particular a coupling fastened to the support rail.The luminaire components are arranged one behind the other in the longitudinal direction, with the support rails of the respective luminaire components being mechanically connected to one another by means of the coupling, and the supply lines which run in the support rails, in particular the conductor wires arranged in the current conducting rails of the luminaire components, being electrically connected to one another in pairs, i.e. one conductor wire of the first luminaire component is connected to one conductor wire of the second luminaire component. This makes it possible to create very elongated luminaires, as is required in a large number of applications. In particular, the current conducting rails of two adjacent luminaire components, the support rails of which are mechanically fixed to one another by a coupling, can be connected to one another by an electrical connector which connects the conductor wires arranged in the two current conducting rails in pairs.In particular, the busbars and the electrical connector are fixed in their position relative to each other by the coupling of the mounting rails of the luminaire components. Thus, a luminaire of the respective system comprises a plurality of

[0012] Support rails and in particular a multitude of mounting bodies and / or current guide rails or a multitude of luminaire components, which are each connected to one another as explained.

[0013] Since generic luminaires are usually very long in the longitudinal direction, often more than 5 m, often more than 10 m, often more than 20 m, often more than 50 m, it is necessary for a large number of support rails to be connected to one another using a generic system in order to create the luminaire. For this purpose, the support rails are usually delivered with the coupling arranged at the factory with one longitudinal section in the respective support rail and another longitudinal section protruding from the support rail, with which it can then be inserted into another support rail to fix the two support rails together.To install the electrical functional elements, in particular the lighting devices, the contact devices are then arranged with their contact sides inside the interior of the support rail on the access side of the current conducting rail so that the functional element connected to the respective contact device can be electrically connected to at least some of the lead wires by means of the contact device. Contacting of the lead wires by the contact device is often carried out in such a way that a mounting body with a pre-mounted contact device is arranged at the open end of the support rail and the contact units of the contact device are inserted into the channels of the current conducting rail, while the contact device is fixed to the mounting body.The contact units are often inserted into the channels for the conducting wires during and as a result of the same movement of the mounting body relative to the support rail with which the mounting body is arranged and fastened to the open end of the support rail in order to close the open side of the support rail. Since a current conducting rail of a generic system typically has a large number of channels arranged next to one another in the direction of arrangement, typically at least ten, preferably at least thirteen, it is not easy to ensure correct contact between the conducting wires arranged in the channels. It must be taken into account that the current conducting rail with all of its channels usually extends over a limited area in the direction of arrangement, so that the current conducting rail, and thus a luminaire produced using the system, does not have to be overly large.In most cases the total length of the current conducting rail in the direction of assembly is less than 20 cm, in particular less than 15 cm. In most cases the channel walls which separate the clear cross sections of two adjacent channels of the current conducting rail have a channel wall thickness of less than 5 mm, in particular less than 4 mm, in particular less than 3 mm. The contact device and its contact units must therefore be carefully aligned relative to the current conducting rail so that its contact units can reach the channels provided for them. In addition, incorrect insertion of the contact device onto the current conducting rail should be prevented where possible by arranging the contact device on the current conducting rail rotated by 180° compared to its intended alignment relative to the current conducting rail.It should be noted that usually each of the conductor wires arranged in the channels of the conductor rail is assigned a specific function, for example the function as a data conductor, neutral conductor, phase conductor or PE conductor, so that correct positioning of the contact device relative to the conductor rail or correct contacting of the contact units on the conductor wires provided for them is necessary for the correct functioning of a luminaire and also in terms of safety aspects.

[0014] In the typical use of a generic system for the realisation of elongated luminaires which have a number of luminaire components, each comprising a conductor rail and a support rail, the transition between two adjacent luminaire components has proven to be particularly critical. When generic systems are used in this way, the provision of a coupling which connects two adjacent support rails to each other ensures that the two support rails are reliably fixed to one another. However, such a fixation is of course not resistant to all external forces, and this is particularly the case when elongated luminaires which have a very large number of luminaire components or support rails arranged one behind the other.If the support rails comprise support rails which are each connected to one another by a coupling, wherein the support rails are mounted on a ceiling, in particular are suspended, a snake-like twist can occur due to movements of the support rails or luminaire components relative to one another. Such twists can quickly have adverse functional effects, for example due to the formation of gaps between two adjacent support rails and / or due to stress on the electrical contacts between the electrical connector and the current conducting rails of two adjacent luminaire components connected by it. In order to avoid such effects wherever possible, a wide variety of measures have been introduced in the prior art in order to optimise the fixing of two adjacent support rails or luminaire components ensured by the coupling as far as possible.For example, scratch springs were incorporated into the coupling. In the intended operating condition, in which two support rails are connected by the coupling, these springs are scratched from the inside against both support rails, thus securing them to each other as reliably as possible. Various geometries of the coupling and associated support rails were also tested, with which the best possible clamping between the coupling and the support rails could be achieved.Although the known measures have already made it possible to achieve very good fixing of two support rails to one another by means of a coupling, such measures have still not proven sufficient to ensure particularly reliable, long-lasting, consistent functionality of the luminaire when high relative forces occur between two support rails, which are particularly the case with luminaires that are very long in the longitudinal direction and comprise a large number of support rails, in particular more than five support rails, and / or with a luminaire that is suspended from a ceiling and comprises a large number of support rails.Complex additional fastening measures, such as screwing the support rails relative to the coupling and / or the provision of additional mechanical clamping components, have proven to be costly, disadvantageous for the use of a system for the realization of an elongated luminaire and undesirable for the overall visual impression of a luminaire realized in this way.

[0015] The present invention is based on the object of

[0016] System for realizing a lamp that is elongated in a longitudinal direction, an elongated lamp and / or a method for realizing a lamp that is elongated in the longitudinal direction or for realizing an arrangement of lamp components, which at least partially eliminates at least one disadvantage of generic systems, lamps and / or methods.

[0017] As a solution to the problem underlying the present invention, the invention proposes a system with the features according to claim 1. The system has a plurality of support rails which are elongated in the longitudinal direction and a coupling provided for connecting two of the support rails. Each of the support rails has a guide for the coupling, the guide being formed at least partially by the support rail side walls of the respective support rail. The coupling extends along the longitudinal direction, starting from a first longitudinal end to a second longitudinal end, so that its longitudinal extension length is defined by the distance between the first and second longitudinal ends. Accordingly, each of the support rails has a first longitudinal end and a second longitudinal end, so that its respective longitudinal extension length is defined by the distance between the first and second longitudinal ends.The coupling is designed to connect a first of the support rails to a second of the support rails in an operating state of the system. Each of the support rails of the system referred to here has a cross-section corresponding to the coupling, so that the first and second support rails can be selected as desired from the plurality of support rails. The operating state designates a defined arrangement of the respectively specified components of the system relative to one another.By inserting a first longitudinal section of the coupling, which comprises the first longitudinal end of the coupling, into a first longitudinal end section of the guide of the first support rail, which comprises the first longitudinal end of the support rail, and by inserting a second longitudinal section of the coupling, which comprises the second longitudinal end of the coupling, into a second longitudinal end section of the guide of the second support rail, which comprises the second longitudinal end of the support rail, the operating state of the system can be realized in which the first and second support rails are fixed relative to one another by the coupling.In the operating state, the coupling rests with an upper and a lower end of its longitudinal section on a respective vertical guide section of the first longitudinal end section of the guide of the first support rail, and with an upper and a lower end of its second longitudinal section on a respective vertical guide section of the second longitudinal end section of the guide of the second support rail. The upper and lower ends of the coupling are preferably formed by at least one of the coupling side walls, in particular by both coupling side walls.The guide of the respective support rail naturally has a plurality of vertical guide sections, at least an upper and a lower vertical guide section, the coupling being arranged in the operating state with its respective longitudinal section between the upper and lower vertical guide section of the guide of the respective support rail in such a way that it rests with an upper end of the longitudinal section on the upper vertical guide section and with a lower end on the lower vertical guide section. As a result, the respective longitudinal section of the coupling is fixed in its position relative to the respective support rail with respect to the vertical direction. The vertical guide sections or the upper and lower ends of the longitudinal section can of course each comprise subsections which can be spaced apart from one another, for example in the transverse direction and / or longitudinal direction.What is important is that the vertical position of this longitudinal section of the coupling and thus of the coupling as a whole relative to the respective support rail is fixed by the upper and lower ends of the longitudinal section of the coupling each resting against a vertical guide section of the respective longitudinal end section of the respective support rail. The coupling, in particular at least one of the coupling side walls, has a transverse coupling projection extending within the second longitudinal section, which is spaced from the second longitudinal end and which, in the operating state, presses transversely against a transverse guide section of the second longitudinal end section of the guide of the second support rail, producing a transverse compression of the coupling relative to the second support rail, in particular between the support rail side walls of the second support rail.Alternatively or preferably, each support rail has a transverse support rail projection within its second longitudinal end section, spaced from its second longitudinal end, wherein in the operating state the transverse support rail projection of the second longitudinal end section of the second support rail presses transversely against a transverse guide section of the coupling assigned to it in a longitudinal end region of the second longitudinal section of the coupling comprising the second longitudinal end of the coupling. The transverse coupling projection and / or the transverse support rail projection preferably have an inclined surface on at least one of their longitudinal ends, in particular at least on their longitudinal end pointing towards the second longitudinal end of the coupling or second support rail, so that the coupling can be inserted with its second longitudinal end into the second longitudinal end of the support rail more easily. The inclined surface can thus form an insertion bevel.Preferably, the respective longitudinal end is rounded. In particular, the transverse coupling projection and / or the transverse support rail projection are formed by a recess formed in a sheet metal, so that the sheet metal has an indentation on the side facing away from the recess formed.

[0018] By the transverse coupling projection being spaced from the second longitudinal end, the coupling can initially be inserted with its second longitudinal end simply into the second longitudinal end of the second support rail without the transverse coupling projection hindering the insertion. The transverse coupling projection is assigned to a transverse guide section of the second longitudinal end section of the guide of the second support rail, against which it presses along the transverse direction in the operating state. By the transverse coupling projection being spaced from the second longitudinal end of the coupling, a free space is provided over the transverse extent of the transverse coupling projection between the second longitudinal end and the transverse coupling projection in a defined vertical region, over which the transverse coupling projection extends.Thus, when the coupling is inserted with its second longitudinal section into the second longitudinal end section of the second support rail to reach the operating state, the coupling initially does not bear against the transverse guide section or bears against the transverse guide section only with a low pressing force, against which the transverse coupling projection presses with a transverse pressing force upon further insertion. This free space preferably extends from the second longitudinal end within the said vertical region uninterruptedly up to the transverse coupling projection. Particularly preferably, the free space extends over at least 50%, in particular at least 70%, in particular at least 80%, in particular at least 90% of the longitudinal extension length of the second longitudinal section of the coupling.The longitudinal extension length of the second longitudinal section of the coupling is determined by the longitudinal extension of the coupling with which it is located in the second support rail in the operating state or overlaps with this along the longitudinal direction. In the operating state, the position of the second longitudinal section of the coupling is fixed relative to the second support rail in relation to the transverse direction. The guide of the second support rail therefore has at least two transverse guide sections in the second longitudinal end section, with the coupling in the second longitudinal section each having a transverse side abutting against one of the transverse guide sections of the guide of the second support rail, as a result of which the second longitudinal section of the coupling is fixed in the transverse direction relative to the second support rail.Accordingly, by pressing the transverse coupling projection against the transverse guide section of the second support rail assigned to it, the coupling is pressed relative to the second support rail along the transverse direction. For example, the transverse coupling projection can press outwards away from the transverse center of the coupling against the transverse guide section of the second support rail assigned to it, with a transverse side of the coupling facing away from the transverse coupling projection pressing transversely outwards against another transverse guide section of the second support rail. With a corresponding design, pressing transversely inwards is of course also possible. In one embodiment, the transverse guide section is formed by one of the support rail side walls.In a preferred embodiment, in the operating state, the coupling is pressed transversally between the support rail side walls of the second support rail by pressing the transversal coupling projection against the transversal guide section of the second support rail assigned to it, so that it presses against the two support rail side walls from the inside. In a preferred embodiment, the coupling has a transversal coupling projection on each of two sides facing away from or towards each other in the transversal direction, to each of which a transversal guide section of the second support rail is assigned, wherein in the operating state the transversal coupling projections press in opposite directions along the transversal direction against the transversal guide section assigned to them.In a preferred embodiment, one of the coupling side walls has the transverse coupling projection. This coupling side wall preferably has a coupling side wall section which extends over the vertical region over which the transverse coupling projection extends, this coupling side wall section extending from the second longitudinal end in the longitudinal direction to the transverse coupling projection and a transverse outer side of this coupling side wall section being spaced less far from the transverse center of the coupling than the transverse outer side of the transverse coupling projection, so that the explained free space is located on the outer side of said coupling side wall section.In one embodiment, each of the coupling side walls has a transverse coupling projection, wherein the transverse coupling projections can each be designed as explained here for a wide variety of embodiments, wherein in particular the two transverse coupling projections extend over a same longitudinal extension section and / or over a same vertical extension section, in particular exclusively within a same longitudinal extension section and / or vertical extension section. Preferably, each of the transverse coupling projections formed by the two coupling side walls presses against the support rail side wall assigned to the respective coupling side wall, in particular in a direction along the transverse direction starting from the transverse center of the coupling outwards.In a preferred embodiment, the transverse coupling projection is spaced from the longitudinal end of the second longitudinal section of the coupling facing the first longitudinal section by less than 30%, in particular less than 20%, in particular less than 10% of the longitudinal extension length of the second longitudinal section of the coupling. The transverse coupling projection is preferably located at the longitudinal end of the second longitudinal section facing the first longitudinal section. Generally preferably, the transverse coupling projection extends from the second longitudinal section into the first longitudinal section of the coupling, so that in the operating state the transverse coupling projection presses against a transverse guide section of the first support rail as well as against a transverse guide section of the second support rail, so that a particularly advantageous fixation relative to both support rails is ensured.At this point it should be noted that, as explained at the beginning, lighting components of systems are often delivered in such a way that each lighting component has a support rail into the first longitudinal end section of which a coupling with its first longitudinal section is already inserted and thus fixed to it. The coupling with the first longitudinal section can therefore already be fixed to the support rail at the factory. Therefore, in simplified embodiments it can be provided that the design of the coupling described here as being advantageous for the simple fixing of two support rails is only present in the second longitudinal section of the coupling, and in particular the associated design of the support rail is also only present in the second longitudinal end section of the support rail.In particularly preferred embodiments, the particularly advantageous embodiment explained here for simple fixing is also provided in the first longitudinal section of the coupling, in particular also correspondingly in the first longitudinal end section of the support rail, so that on the one hand reliable assembly can be achieved particularly easily even at the factory, and on the other hand a proper use of the system for realizing an elongated luminaire or for connecting luminaire components, the coupling can be pulled out of its pre-assembled state from the first longitudinal end section of a support rail with its first longitudinal section in a simple manner depending on the requirements at the construction site and can then be inserted into this or another support rail.Generally, the first longitudinal section of each coupling of the system is preferably designed to be compatible with the first longitudinal end section of each support rail of the system, and the second longitudinal section of each coupling is designed to be compatible with the second longitudinal end section of each support rail of the system, so that the explained interaction of the coupling with the two support rails is provided for each coupling in interaction with any two of the support rails selected.Generally, the first longitudinal section and second longitudinal section of the coupling and the first longitudinal end section and second longitudinal end section of each support rail are preferably designed to correspond to one another in such a way that the first longitudinal section of the coupling is just as compatible with the second longitudinal end section of each support rail as is described here for the first longitudinal end section, and the second longitudinal section of the coupling is just as compatible with the first longitudinal end section of each support rail as is described here with reference to the second longitudinal end section of each support rail.Thus, in one embodiment for realizing a fixation of two support rails, as explained here for various embodiments, the first longitudinal section of the coupling can also be arranged in a second longitudinal end section of one of the support rails and the second longitudinal section of the coupling can be arranged in a first longitudinal end section of another of the support rails.

[0019] In one embodiment, the vertical guide sections of the second longitudinal end section of the guide of the second support rail are vertically and / or horizontally spaced from the transverse guide section of the guide of the second support rail, against which the transverse coupling projection provided in the second longitudinal section of the coupling presses in the operating state. By spacing the vertical guide sections from the transverse guide section, a reliable and precise fixing of the vertical relative position of the coupling relative to the second support rail can be ensured by the vertical guide sections, without the transverse pressing of the transverse projection against the transverse guide section, by means of which the transverse position of the coupling relative to the second support rail is reliably and precisely fixed, counteracting this.It is therefore generally preferred that the determination of the vertical position and the determination of the transverse position of the coupling relative to the second support rail influence each other as little as possible, so that the determination can be guaranteed as permanently and precisely as possible. In one embodiment, the support rail is produced from a sheet metal by forming the sheet metal, wherein the vertical guide sections of the support rail are each formed by a sheet metal section which is connected by at least one forming operation running along the vertical direction and along the transverse direction to a further sheet metal section which forms the transverse guide section. In one embodiment, the transverse guide section is arranged closer to a transverse center of the support rail or further away from the transverse center of the support rail than the vertical guide sections.In one embodiment, each of the support rail side walls of each support rail forms an upper and a lower vertical guide section of the second longitudinal end section of the guide of the respective support rail, wherein the upper and lower vertical guide sections are spaced apart from one another by a vertical distance. The transverse guide section is preferably arranged vertically above the upper vertical guide section or vertically below the lower vertical guide section. In the operating state, the coupling rests with an upper end of its second longitudinal section on the upper vertical guide section of the second longitudinal end section of the second support rail and with the lower end of its second longitudinal section on the lower vertical guide section of the second longitudinal end section of the guide of the second support rail.By arranging the transverse guide section vertically outside the vertical distance provided between the upper and lower vertical guide ends, it can be ensured that pressing the transverse coupling projection against the transverse guide section has as little impact as possible on the precise fixing of the vertical position of the coupling with its second longitudinal section relative to the respective support rail. In one embodiment, the upper and lower vertical guide sections are connected to one another by a wall section of the respective support rail side wall running along the vertical direction. The wall section extends vertically within the said vertical distance between the upper and lower vertical guide sections, in particular over at least 80% of the vertical distance.The wall section can thus be directly adjacent to the upper and lower vertical guide sections or be connected to each of them by a connecting wall section. The wall section is preferably designed to run perpendicular to the transverse direction, in particular as a flat wall section. This can ensure particularly high rigidity. The wall section preferably extends over at least 90% of the vertical distance, whereby particularly high rigidity can be provided. The wall section can be designed to be continuously closed or at least have one passage.

[0020] In one embodiment, the transversal

[0021] Coupling projection spaced apart in the vertical direction from the upper and lower ends of the second longitudinal section. In one embodiment, the transverse coupling projection is spaced apart in the longitudinal direction from the upper and lower ends of the second longitudinal section. In one embodiment, the transverse coupling projection is spaced apart in the transverse direction from the upper and lower ends of the second longitudinal section.

By the transverse support rail projection being spaced longitudinally from the second longitudinal end of the support rail,As already explained here analogously to the transverse coupling projection, the coupling, in order to realize the operating state, is first inserted, for example, with its second longitudinal end section into the support rail, without the transverse support rail projection hindering the insertion, so that only after a first insertion does a transverse pressing of the support rail projection against the transverse guide section of the coupling take place. Accordingly, as explained analogously to the transverse coupling projection, a free space is preferably provided between the second longitudinal end of the support rail and the support rail projection in a vertical extension area over which the transverse support rail projection extends,which extends over the transverse extent of the transverse support rail projection.

Generally preferably, in the operating state, the transverse coupling projection is further spaced from the second longitudinal end of the coupling than the transverse support rail projection of the second longitudinal end section of the second support rail. Generally preferably, the upper end of the second longitudinal section of the coupling, which in the operating state is attached to one of the vertical guide sections,In particular, it rests against the upper vertical guide section of the second support rail, arranged longitudinally between the transverse support rail projection and the transverse coupling projection. This allows the vertical position to be determined in a longitudinal region that lies between two transverse compression regions of the coupling relative to the support rail.

[0023] In one embodiment, the support rail side walls of each support rail each have, in an upper end region, an indentation with an indentation base forming a transverse end of the indentation and with at least one indentation side forming a vertical end of the indentation. The indentation is preferably U-shaped in cross-section, i.e. in the cross-section running perpendicular to the longitudinal direction, so that the indentation base is formed by the U-base and the indentation side is formed by one of the U-legs. Such an indentation can improve the stability of the support rail and / or serve to fix, for example, a current conducting rail and / or the coupling and / or a mounting element. The indentation forms an undercut in the support rail side wall, which leads to a corresponding fixation of the current conducting rail or mounting element or

[0024] Coupling can be used. In one embodiment, the upper vertical guide section of the respective support rail side wall is formed by the indentation side. In one embodiment, the transverse guide section of the support rail is formed by the

The indentation is preferably an indentation running from the outside to the transverse center of the support rail. The support rail is preferably produced by forming a sheet metal part, the indentation being formed by forming the sheet metal part.

[0026] In one embodiment, each support rail side wall has a support rail side wall section which extends vertically from a defined upper vertical position to a defined lower vertical position and which has a vertical extension length defined between the upper and lower vertical positions which is less than 30%, in particular less than 20%, in particular less than 15%, in particular less than 10% of a total vertical extension length of the respective support rail.

Accordingly, the support rail can have a first and a second transverse guide section in the first and second longitudinal end sections, both of which are also provided within the support rail side wall section, in particular together with the at least one transverse support rail projection. Preferably, the respective transverse guide section and the respective transverse support rail projection extend exclusively within the support rail side wall section.Preferably, the support rail side wall section is formed by the explained indentation formed by the respective support rail side wall, in particular by the indentation base.

[0027] In one embodiment, the transverse coupling projection extends within the first longitudinal section of the coupling, so that the transverse coupling projection extends not only in the second longitudinal section but also in the first longitudinal section of the coupling. In one embodiment, the transverse coupling projection has two spaced-apart coupling projection sections, one of which is provided in the first longitudinal section and another in the second longitudinal section of the coupling. In one embodiment, the transverse coupling projection extends continuously from the second longitudinal section of the coupling into the first longitudinal section of the coupling. Generally speaking, the first and second longitudinal sections of the coupling lie directly against one another, so that the coupling consists of a first and a second longitudinal section.In one embodiment, the transverse coupling projection presses transversely against a transverse guide section of the first longitudinal end section of the guide of the first support rail in the operating state, producing a transverse compression of the coupling relative to the first support rail, in particular between the support rail side walls of the first support rail. The arrangement and design of the transverse coupling projection in the first longitudinal section and its interaction with the first longitudinal end section of the guide of the first support rail can be provided in embodiments accordingly, as explained for the arrangement and design of the transverse coupling projection in the second longitudinal section of the coupling or its interaction with the second longitudinal end section of the guide of the second support rail in the operating state.

[0028] In one embodiment, each support rail, in particular at least one of the support rail side walls of each support rail, has a transverse support rail projection within its first longitudinal end section at a distance from its longitudinal end, wherein in the operating state the transverse support rail projection of the first longitudinal end section of the first support rail presses transversely against a transverse guide section of the coupling assigned to it in a longitudinal end region of the first longitudinal section of the coupling comprising the first longitudinal end. Preferably, in the operating state the transverse coupling projection is arranged along the longitudinal direction between the transverse support rail projection of the second longitudinal end section of the second support rail and the transverse support rail projection of the first longitudinal end section of the first support rail.The transverse support rail projection, which is preferably provided in the first longitudinal end section of a support rail, and the transverse guide section of the coupling, which is preferably provided in the first longitudinal section of the coupling, can be designed and arranged accordingly, as explained here in connection with the transverse support rail projection explained in the second longitudinal end section of the support rail or the transverse guide section of the coupling provided in the second longitudinal section of the coupling. In particular, the indentation, as explained above, in particular the indentation base, can form the transverse support rail projections provided in the first and second longitudinal end sections of the support rail and in particular the transverse guide sections provided in the first and second longitudinal end region of the support rail.Generally preferably, the at least one transverse coupling projection is spaced apart in the longitudinal direction from each of the said transverse guide sections of the coupling, against which a transverse support rail projection rests in the operating state, in particular by at least 10%, in particular by at least 20% of the longitudinal extension length of the coupling. Generally preferably, the at least one transverse support rail projection is spaced apart in the longitudinal direction from each of the said transverse guide sections of the support rail, in particular by at least 10%, in particular by at least 20% of the longitudinal extension length of the coupling.

[0029] In one embodiment, the coupling has at least one scraper spring with a first and a second spring section, which are deflected in the operating state starting from a rest position. In the operating state, the first spring section presses against the first support rail with a first spring force and the second spring section presses against the second support rail with a second spring force. Preferably, the first and second spring forces run along the vertical direction. The scraper spring can ensure a particularly good fixation of the support rails to one another with respect to the longitudinal direction. Preferably, the first and second

[0030] The spring section is firmly fixed in position on one of the coupling side walls and, in the operating state, presses against a corresponding pressing section of the support rail, which is formed in particular by the indentation explained. Particularly preferably, the first and second spring sections are formed by a one-piece component that is firmly fixed in position on one of the support rail side walls or on the support rail base. In one embodiment, the transverse coupling projection and the scraper spring extend in the same longitudinal region.Thus, in a specific longitudinal region which is spaced in particular by less than 20%, in particular less than 10% from the mutually facing longitudinal ends of the first and second support rails in the operating state, a transverse compression can take place to fix the transverse position of the support rails to one another and a vertical compression of the scraper spring against both support rails to fix their longitudinal position by the scraper spring pressing with the respective spring section against the respective support rail in a scraping manner. In one embodiment, the transverse coupling projection is arranged vertically above the spring sections of the scraper spring and is thus arranged closer to the support rail base than the spring sections.

[0031] In one embodiment, the coupling side walls each have a gap with a vertical length vertically between their upper and lower ends of at least one of the first and second longitudinal sections, in particular of the first and second longitudinal sections respectively, within a same longitudinal region in which at least one of the upper and lower ends is arranged. The gap is hole-like, i.e. designed as a passage through the respective coupling side wall. Preferably, at least one of the upper and lower ends is arranged over its entire longitudinal extent within the longitudinal region over which the gap extends. In the event of vertical compression acting on the upper and lower ends, the coupling side walls are compressible within this longitudinal region by compressing the gap, thereby reducing their vertical length.The gap, which is provided in the same longitudinal region of at least one of the upper and lower ends, can thus result in simplified compressibility of the respective coupling side wall over the defined longitudinal region of its longitudinal extension length. This can particularly simplify the insertion of the coupling into a guide of a support rail. At the same time, the defined vertical length of the gap determines maximum compressibility. The vertical length is preferably less than 5 mm, in particular less than 3 mm, in particular less than 2 mm.The gap can be specifically integrated into the geometry of the coupling so that when a defined vertical compression force is applied, it results in a defined deformability of the respective coupling side wall, so that despite the ease of insertion, the coupling can be very well fixed relative to the support rail and thus its vertical position relative to the support rail can be determined. Generally speaking, the gap is preferably provided within a wall section of the coupling which runs perpendicular to the transverse direction and is in particular flat and which, in particular in the operating state, runs parallel to the explained wall section of the support rail, which in one embodiment connects the upper and lower vertical guide sections to one another.Preferably, this wall section of the coupling side wall extends over at least 80%, in particular over at least 90% of a vertical distance which is provided between the upper and lower ends, in particular the said wall section itself directly forms the upper and lower ends of the respective longitudinal section of the coupling at its upper and lower ends.

[0032] In one embodiment, each of the support rail side walls of each support rail forms a U-shaped receptacle with a support rail side wall section, which receptacle forms part of the guide for the support rail. In the operating state, one of the coupling side walls is arranged in the receptacle of the support rail side wall assigned to it, so that due to its U-shaped design, the support rail side wall section surrounds the coupling side wall on both sides, in particular transversely on both sides. By encompassing the coupling side wall on both sides, the coupling side wall is guided particularly well relative to the support rail side wall section. The support rail side wall section preferably extends along a specific direction, in particular the transverse direction, on both sides of a specific coupling side wall section, which extends flatly perpendicular to the specific direction.Preferably, the U-shaped base of the U-shaped receptacle forms a lower vertical guide section of the guide of the support rail. Preferably, the U-shaped receptacle is provided by a vertical end region of the support rail side wall facing away from the support rail base along the vertical direction. Such a U-shaped receptacle is particularly easy to realize by forming a sheet metal to create a support rail and can result in advantageous stability of the guide.In one embodiment, the support rail side wall section of at least one of the support rail side walls in the second longitudinal end section of the guide of the second support rail and the coupling side wall arranged in the receptacle formed by it in the operating state in the second longitudinal section of the coupling each have a recess, wherein in the operating state the recesses formed by the support rail side wall and the coupling side wall overlap in sections.Preferably, the support rail side wall section runs with respect to a specific direction, in particular the transverse direction, on both sides along a coupling side wall section and runs over the extension of the coupling side wall section perpendicular to this specific direction on both sides of the coupling side wall section, wherein the recesses are provided within the extension region of the coupling side wall section which it has perpendicular to this specific direction. In one embodiment, an edge delimiting the recess of the coupling side wall in a direction along the longitudinal direction lies within the longitudinal extension of the recess in the support rail side wall. In one embodiment, an edge delimiting the recess of the support rail side wall in a direction along the longitudinal direction lies within the longitudinal extension of the recess in the coupling side wall.In one embodiment, an edge delimiting the recess of the coupling side wall in one direction along the longitudinal direction lies within the longitudinal extent of the recess of the support rail side wall and an edge delimiting the recess of the support rail side wall in the opposite direction along the longitudinal direction lies within the longitudinal extent of the recess of the coupling side wall.Because the recesses of the coupling side wall and the support rail side wall overlap in sections, this overlap being at least an overlap in the longitudinal direction and in particular in the vertical direction, but at least one of the recesses extending beyond the other of the recesses in relation to the longitudinal direction, so that an edge delimiting the other recess lies within its longitudinal extension region, this edge of the other recess can be particularly easily accessible for a tool with which a relative force acting along the longitudinal direction can be applied between the coupling side wall and the support rail side wall, so that the coupling is moved relative to the support rail along the longitudinal direction, for example in order to move the coupling a final distance along the longitudinal direction in order to reach the operating state, or starting from the operating state in order to move a first distance along the longitudinal direction.At least one of the recesses is designed as a passage in the respective side wall, i.e. the support rail side wall or coupling side wall, so that the other recess is accessible through this recess. The other of the recesses can, for example, also be formed by an embossing, the edge of which is accessible through one of the recesses. Preferably, at least the recess provided in the support rail side wall is designed as a passage. Preferably, both recesses are designed as passages, since a tool can then engage the respective edge particularly well and, moreover, the tool can be guided particularly well in the two passages. The present embodiment relating to the explained provision of the recesses which overlap at least in sections generally represents in itself a separate inventive solution to the described problem underlying the invention.However, this solution can be particularly advantageously combined with the embodiments of other solutions described herein. In particular, the recesses explained and the embodiments described herein in this context can be particularly advantageously combined with those embodiments or solutions according to the invention in which an explained transverse support rail projection and / or an explained transverse coupling projection is provided. In this case, by acting on the corresponding edge of the corresponding recess, a particularly high force can be applied to realize and / or release the operating state along the longitudinal direction between the coupling side wall and the support rail side wall, which force is required in the advantageous embodiments due to the provision of the respective transverse projection.Generally preferably, an outermost transverse end of the transverse coupling projection and / or of the transverse support rail projection, with which the respective projection thus projects furthest relative to adjacent regions, lies in a plane running perpendicular to the transverse direction and extends in this plane over a longitudinal extension length, wherein the longitudinal extension length is smaller than the longitudinal extension length of each of the two recesses, in particular smaller than the longitudinal extension length of the overlap of the recesses in the operating state, wherein in particular both recesses have a longitudinal extension length of less than 20 mm, in particular less than 15 mm, in particular less than 10 mm and / or the overlap region, over which the recesses overlap along the longitudinal direction, has a longitudinal extension length of less than 10 mm, in particular less than 8 mm, in particular less than 6 mm.In such a particularly advantageous embodiment, it is advantageously ensured that, precisely when the respective transverse projection rests against the corresponding transverse guide section with a particularly high pressing force, namely in the area in which it projects to the maximum, a sufficiently high force can be applied to the edge of the respective recess in a simple manner using a tool to achieve the operating state or, starting from the operating state, a correspondingly sufficient force can be applied easily to release the coupling from the support rail.

[0033] In one embodiment, the recess provided in the support rail side wall section is provided in a region of the support rail side wall section forming a side of the receptacle facing the transverse center of the support rail, wherein the recess in the coupling side wall is accessible from the transverse center outwards through the recess in the support rail side wall. A region of the support rail side wall section forming a side of the receptacle facing away from the transverse center of the support rail is preferably designed to be continuously closed at the level of the recesses. The provision of the closed region can enable the provision of a closed outer side of the support rail. Because the recess in the coupling side wall is accessible from the transverse center through the recess in the support rail side wall, a tool can be used particularly easily from the interior of the support rail to reach the operating state orReleasing the operating state are introduced into the recesses. In one embodiment, the recess provided in the coupling side wall extends, starting from the edge which delimits it along the longitudinal direction and which lies within the longitudinal extension region of the recess in the support rail side wall, towards the second longitudinal end without interruption up to a boundary which delimits the recess provided in the support rail side wall and which is thus formed by the support rail, wherein it extends beyond this boundary in particular towards the second longitudinal end.In one embodiment, the recess provided in the support rail side wall extends, starting from the edge which delimits it along the longitudinal direction and is preferably provided within the longitudinal extension region of the recess in the coupling side wall, towards the first longitudinal end without interruption up to a boundary which delimits the recess provided in the coupling side wall and is thus formed by the coupling side wall. In one embodiment, the recess provided in the coupling side wall extends, starting from the edge which delimits it along the longitudinal direction and is preferably provided within the longitudinal extension region of the recess in the support rail side wall, towards the first longitudinal end without interruption up to a boundary which delimits the recess provided in the support rail side wall and is thus formed by the support rail, in particular beyond this boundary.In one embodiment, the recess provided in the support rail side wall extends, starting from the edge which delimits it along the longitudinal direction and which preferably lies within the longitudinal extension region of the recess in the coupling side wall, towards the second longitudinal end without interruption up to a boundary which delimits the recess provided in the coupling side wall and is thus formed by the coupling side wall, in particular beyond it. The terms "edge" and "boundary" are used here purely terminologically in order to distinguish between the edges or boundaries of the respectively overlapping recesses. Basically, the term "edge", like the term "boundary", describes one end of the respective recess. In the cases described and explained.

[0034] In some embodiments, a tool can be particularly advantageously introduced into the overlapping area of ​​the two recesses, which tool can be supported on the one hand on the edge delimiting the recess of one of the coupling side wall and the support rail and on the other hand on the edge delimiting the recess of the other boundary delimiting the coupling side wall and the support rail side wall, so that a relative force can be applied between them along the longitudinal direction by the tool, whereby a displacement of the coupling relative to the support rail along the longitudinal direction can be generated in a simple manner.

[0035] In one embodiment, the support rail side wall section of each of the support rail side walls in the second longitudinal end section and the coupling side wall arranged in the receptacle formed by it in the operating state each has a recess, i.e. each of the two coupling side walls which are arranged in the respective receptacle formed by the support rail side wall section of the support rail side wall respectively assigned to them. In the operating state, the recesses formed by the support rail side wall and by the coupling side wall arranged in the receptacle of the respective support rail side wall overlap in sections. Thus, such overlapping recesses are provided on each side of the support rail or coupling, so that on both support rail side walls orBecause of the overlapping recesses provided, a force as explained can be easily applied to each of the two coupling side walls using a tool. In one embodiment, an edge delimiting the recess of a first coupling side wall in a direction along the longitudinal direction lies within the longitudinal extent of the recess of a first support rail side wall, and an edge delimiting the recess of a second coupling side wall in a direction opposite to the aforementioned direction along the longitudinal direction lies within the longitudinal extent of the recess of a second support rail side wall. The first and second support rail side walls or the first and second coupling side walls are the two explained side walls of the support rail or the coupling.By having the edge delimiting the recess of the coupling side wall in one direction along the longitudinal direction within the longitudinal extent of the recess of the supporting rail side wall in one pair of coupling side wall and supporting rail side wall and by having the edge delimiting the recess of the other coupling side wall in the opposite direction within the longitudinal extent of the recess of the associated supporting rail side wall in the other pair of coupling side wall and supporting rail side wall, the overlapping recesses of one of the two pairs can be used to realize the operating state and the overlapping recesses of the other pair of coupling side wall and supporting rail side wall can be used to release the operating state.Generally, an edge delimiting the recess of the first support rail side wall in the aforementioned opposite direction lies within the longitudinal extent of the recess of the first coupling side wall, and an edge delimiting the recess of the second support rail side wall in the aforementioned direction, i.e., opposite to the opposite direction, lies within the longitudinal extent of the recess of the second coupling side wall. Accordingly, as explained, a relative force can be applied between the edges of the recesses in a particularly advantageous manner between the support rail and the coupling for releasing or achieving the operating state.

[0036] In one embodiment, the support rail side wall section of at least one of the support rail side walls in the first longitudinal end section and the coupling side wall arranged in the receptacle formed by it in the operating state each have a recess in the first longitudinal section, wherein in the operating state the recesses formed by the support rail side wall and the coupling side wall overlap in sections and an edge delimiting the recess of the coupling side wall in one direction along the longitudinal direction lies within the longitudinal extent of the recess in the support rail side wall and / or an edge delimiting the recess of the support rail side wall in the opposite direction along the longitudinal direction lies within the longitudinal extent of the recess in the coupling side wall.

Furthermore, it should be generally noted that any longitudinal end section of the support rail always comprises one of the longitudinal ends of the support rail and extends from the longitudinal end to the longitudinal center of the support rail. Generally preferably, the longitudinal end section has a longitudinal extension length of at least 10 cm, in particular at least 15 cm, in particular less than 50 cm, in particular less than 40 cm.

Generally preferably, the system has a plurality of longitudinally elongated current conducting rails which have longitudinally elongated channels arranged next to one another in an array direction running perpendicular to the longitudinal direction and which are open on an access side of the current conducting rail. In each of the channels, at least one longitudinally elongated conductor wire is arranged.

[0039] In one embodiment, the system comprises at least one mounting body which, in an operating state of the system, is arranged on the open side of one of the support rails and is fixed to the support rail and which, together with the support rail, encloses an interior space provided for accommodating electrical components.

[0040] The invention further relates to a method for realizing an arrangement of lighting components.

[0041] Accordingly, the method relates to the realization of a longitudinally elongated luminaire comprising a plurality of luminaire components. Each of the luminaire components has at least one elongated support rail with a U-shaped cross-section, designed to receive mounting bodies equipped with illuminants, each of which has a support rail base extending in a transverse direction between two support rail side walls and an open side opposite the support rail base in a vertical direction, wherein the support rails are connected to one another by means of a coupling having a coupling body with a U-shaped cross-section, which is formed by a coupling base and two coupling side walls, wherein each of the support rails has a guide for the coupling, which is formed at least partially by its support rail side walls. In a first method step, the coupling,while it is already arranged with a first longitudinal section comprising a first longitudinal end of the coupling in a first longitudinal end section of the support rail of the first luminaire component, with a second longitudinal end inserted into a second longitudinal end section of the guide of the support rail of a second luminaire component until a transverse coupling projection rests on the second longitudinal end of the second support rail and / or a transverse support rail projection rests on the second longitudinal end of the coupling. In a subsequent second method step, the coupling is inserted further with the second longitudinal end into the support rail of the second luminaire component,while the transverse coupling projection presses transversely against a transverse guide section of the support rail of the second luminaire component and / or the transverse support rail projection presses against a transverse guide section of the coupling. Thus, during the second method step, the coupling is inserted further with its second longitudinal end into the support rail of the second luminaire component,while the transverse coupling projection and / or transverse support rail projection presses against the associated transverse guide section with a transverse pressing force and thus generates increased friction. Preferably, towards the end of the first method step, for moving the coupling along the longitudinal direction until it rests on the transverse support rail projection or until the support rail rests on the transverse coupling projection, a lower force acting along the longitudinal direction between the coupling and the support rail of the second luminaire component is required than at the beginning of the second method step. Thus, due to the transverse pressing force exerted by the coupling projection or support rail projection, a higher force acting along the longitudinal direction between the coupling and the support rail of the second luminaire component is required.so that a relative displacement of the coupling to the support rail is still possible to achieve the operating state. In one embodiment, a tool is used during the second method step, which is inserted through a recess provided in one of the support rail side walls into a recess provided in one of the coupling side walls or is inserted through a recess provided in one of the coupling side walls into a recess provided in one of the support rail side walls of the support rail of the second luminaire component, wherein during the second method step, by means of this tool, a force is applied between an edge delimiting the recess in the support rail side wall along the longitudinal direction and an edge delimiting the recess in the coupling side wall, through which force the coupling is inserted with its second longitudinal end further into the support rail of the second luminaire component,while the transverse coupling projection presses transversely against one of the support rail side walls of the support rail of the second luminaire component. The tool can particularly preferably be supported on the edge or boundary of the respective recess of the coupling side wall and the support rail side wall, so that by applying a force acting along the longitudinal direction between the edge and boundary of the two different recesses using the tool, the required force acting along the longitudinal direction to displace the coupling to achieve the operating state can be applied.

[0042] The invention further relates to a method for releasing two lighting components starting from an operating state, wherein each of the lighting components has at least one elongated support rail with a U-shaped cross-section, designed to receive mounting bodies equipped with lighting means, each of which has a support rail base extending in a transverse direction between two support rail side walls and an open side opposite the support rail base in a vertical direction, wherein the support rails are connected to one another by means of a coupling having a coupling body with a U-shaped cross-section, which is formed by a coupling base and two coupling side walls, wherein each of the support rails has a guide for the coupling, which is formed at least partially by its support rail side walls. In the operating state, a firstA longitudinal section of the coupling is arranged in a first longitudinal end section of the guide of the support rail of a first of the luminaire components, and a second longitudinal section of the coupling comprising a second longitudinal end of the coupling is arranged in a second longitudinal end section of the guide of the support rail of a second of the luminaire components, wherein in the operating state the first and second luminaire components are fixed relative to one another by the coupling. The invention accordingly relates to a method for releasing the two luminaire components starting from the operating state.

[0054] An embodiment of such a luminaire 100 is shown schematically in a highly simplified manner. Such a luminaire 100 is elongated in the longitudinal direction X and has a plurality of support rails 1, 10 which are arranged one behind the other in the longitudinal direction X. The embodiment shown has a first support rail 1 and a second support rail 10. The support rails 1, 10 each have a U-shaped cross-section perpendicular to the longitudinal direction X, which defines an interior of the support rail. Together with mounting bodies 6 arranged on their open side and also arranged one behind the other in the longitudinal direction X, they enclose an interior of the luminaire 100 perpendicular to the longitudinal direction X. The same or different electrical functional elements can be arranged on the different mounting bodies 6.In the described embodiment, on each of the mounting bodies 6, an LED module radiating downwards in the vertical direction Z is arranged outside the interior, and an operating device for supplying the LED module is arranged inside the interior, so that the LED module and operating device are arranged on vertical sides of the mounting body 6 facing away from one another, which is generally advantageous according to the invention. Furthermore, a light-permeable cover 101 is provided below each mounting body 6, through which the LED module can radiate light downwards and which can have optically effective sections assigned to the LED module for influencing the light distribution. A system according to the invention generally preferably comprises such covers 101.In further embodiments, further mounting bodies 6 can be provided, which are designed as blind modules and thus do not carry any electrical functional element and which only serve to close off the open side of one of the support rails 1, 10.

[0055] Figure 2, comprising Figures 2a, 2b, 2c, 2d, 2e, 2f and 2g, shows, for explanatory purposes, various components of an embodiment of a system according to the invention which are suitable, for example, for realizing a luminaire 100 according to Figure 1. The described embodiment comprises a plurality of support rails 1, 10, each of which has an identical cross-section. Figure 2a shows the cross-section of a first support rail 1 and the common cross-section of the first support rail 1 and of the coupling 2 arranged in its first longitudinal end section of the described embodiment. It can be seen from the illustrations according to Figure 2a that the support rail 1 has a support rail base 11 and two support rail side walls 12 extending from the support rail base 11 along the vertical direction Z. Each of the support rail side walls 12 forms a U-shaped recess 121 in cross-section in an upper end region.In general, it should be noted at this point that the upper end region, starting from the uppermost end of the support rail 1, preferably extends over at least 5% and in particular less than 50%, in particular between 5% and 40%, in particular between 10% and 30% of the vertical extension length of the support rail 1, wherein its upper end is defined by the uppermost end of the support rail 1. Each of the support rail side walls 12 furthermore has a transverse support rail projection 13, which in the present case is formed by the indentation 121. Furthermore, the support rail side walls 12 each have a support rail side wall section which forms a U-shaped receptacle 122, the open side of which points towards the support rail base 11 along the vertical direction Z, which is generally advantageous according to the invention.Generally preferably, the support rail side wall section forms a vertical end region of the respective support rail side wall 12, wherein the vertical end region preferably extends over a vertical extension length starting from the lowest vertical end of the support rail 1 over at least 5% and less than 50%, in particular between 5% and 40%, in particular between 10% and 30% of the vertical extension length of the support rail 1. The U-shaped receptacle 122 represents part of the guide of the support rail 1, which is designed to receive the coupling 2, as shown in the corresponding cross-sectional view in Figure 2a.Furthermore, each support rail side wall 12, generally advantageous according to the invention, has a holding projection 123, which is designed, for example, as a stop for a mounting body 6 and / or as a holding projection 123 corresponding to a holding spring provided on the mounting body 6, so that by means of the holding projections 123, a mounting body 6, generally advantageous according to the invention, can be reliably arranged on the open side of the support rail 1 and fixed to the latter. In the operating state, a coupling 2 of the described embodiment is arranged in a first longitudinal end section of the first support rail 1. The coupling 2 has a coupling body with a U-shaped cross-section, which has a coupling base 21 and two coupling side walls 22 extending away from the coupling base 21 along the vertical direction Z.The coupling side walls 22 each rest with a lower end on a lower vertical guide section and with an upper end on an upper vertical guide section of the guide formed by the support rail 1, wherein the upper and lower vertical guide sections in the described embodiment and generally advantageously according to the invention are each formed by the support rail side walls 12 of the support rail 1. In addition, the coupling side walls 22 each rest with at least a vertical section along the transverse direction Y from the inside on one of the support rail side walls 12 assigned to them, so that the coupling 2 is fixed in its position relative to the support rail 1 in the operating state both with respect to the vertical direction Z and with respect to the transverse direction Y by a positive fit, which is generally advantageous according to the invention.According to the invention, the position of the coupling 2 relative to the support rail 1 can generally be advantageously determined on the one hand by the transverse and vertical compression of the coupling 2 relative to the support rail 1, by which a frictional connection is provided, and on the other hand by a scratch spring (not shown in the present figures), which is fixed to the coupling body and scratches against the support rail 1 from the inside with a spring section and thus further inhibits a relative movement between the support rail 1 and the coupling 2.

[0056] In Figures 2b, 2c, 2d, 2e, 2f and 2g the transition in the

[0057] Operating state between two support rails 1, 10 arranged one behind the other and fixed to one another in the operating state, is explained on the basis of the representation of various components of the system in their respective positions which they occupy in the operating state. Figure 2b shows a schematic view of a second longitudinal end of the second support rail 10, whereas Figure 2c shows a view of a first longitudinal end of a first support rail 1, wherein a first longitudinal section of a coupling 2 of the system is already arranged in a first longitudinal end section of the support rail 1. From a combination of Figures 2b and 2c it can be seen that a current conducting rail 3 with channels which are open on an access side of the current conducting rail 3 is arranged on the support rail base 11 of the second support rail 10, wherein in each of the channels a conducting wire 4 is arranged which is accessible from the access side of the current conducting rail 3.From Figure 2f it can be seen that the current conducting rail 3 has holding sections 31 over a considerable area of ​​its longitudinal extent, by means of which it is fastened to the support rail 1 in the operating state, with two holding sections 31 adjacent along the longitudinal direction X being spaced apart from one another by a distance. An electrical connector 5 is fixed to the coupling 2 and is connected with its first connection side to the lead wires 4 which are arranged accordingly in the current conducting rail 3 of the first support rail 1, as is explained in Figure 2b with reference to the current conducting rail 3 and the second support rail 10. The second support rail 10 and the first support rail 1 are used in a typical use according to the invention, i.e. in a typical method for connecting two lighting components orto create an elongated light, connected to one another by moving the first support rail 1 along the longitudinal direction X towards the second support rail 10 and in the process introducing the second longitudinal section of the coupling 2, which in the illustration shown in Figure 2c projects along the longitudinal direction X from the first support rail 1, into the guide of the second support rail 10. The first support rail 1 with the coupling 2 fixed thereto and the second support rail 10 are moved towards one another with their mutually facing longitudinal ends until their longitudinal ends abut one another. Thus, in a generally advantageous manner according to the invention, the second longitudinal end of the second support rail 10, which is shown in Figure 2b, rests against the first longitudinal end of the support rail 1 in the operating state or is only spaced from it by a small gap.The electrical connector 5 is explained in more detail in Figures 2d and 2e, wherein for better explanation in the illustration according to Figures 2d and 2e the coupling 2 is hidden so that the electrical connector 5 can be seen more clearly. The electrical connector 5 has an insulating plastic housing by means of which it is fixed to the coupling 2. In this plastic housing there are provided a plurality of connecting devices which are arranged one behind the other in an array direction A and at each of whose two longitudinal ends a spring contact is provided for receiving a respective lead wire. Each spring contact comprises a base body and a spring body 51, wherein the base bodies of the two spring contacts comprised by a specific connecting device are each formed by a common body 52.As can be seen from Figure 2g, in the operating state, the conductor wires 4 of the current conducting rails 3, which are arranged in one of the first and second support rails 1, 10, are electrically connected to one another by the base bodies or the body 52 and the spring bodies 51. In this case, exactly one conductor wire 4, which is arranged in the current conducting rail 3 arranged in the first support rail 1, is electrically connected to exactly one conductor wire 4, which is arranged in the current conducting rail 3 arranged in the second support rail 10. For this purpose, a first spring body 51 provided on the first connection side of the electrical connector 5 presses a first conductor wire 4 of this pair of conductor wires 4 against the body 52 and a second spring body 51 provided on the second connection side of the electrical connector 5 presses a second conductor wire 4 of said pair of conductor wires 4 against the body 52.Since the body 52 and preferably also the spring bodies 51 are designed to be electrically conductive, the two lead wires 4 of the pair are thus electrically conductively connected to one another. While Figure 2g shows the electrical connection of the lead wires 4, which are arranged in the two support rails 1, 10 or are encompassed by the two luminaire components, Figure 2f shows the corresponding arrangement in the operating state of the current conducting rails 3, which are arranged in the two support rails 1, 10, and the electrical connector 5 with its connector housing, specifically with a view of the rear side facing away from the access side of the current conducting rail 3, which in the operating state points towards the support rail base 11 of the support rails 1, 10.The views of the first longitudinal end of the first support rail 1 shown in Figures 2d and 2e, in which various components of the system are not shown so that the longitudinal section of the connector 5 or its connector housing or its protruding spring contacts projecting from the first support rail 1 beyond its first longitudinal end can be seen, serve to illustrate that the second lighting component, i.e. the second support rail 10 with the current conducting rail 3 arranged therein and the lead wires 4 arranged therein, can be pushed onto the first longitudinal end of the support rail 1 in a simple manner by pushing it in the longitudinal direction X in order to implement the operating state, such that the lead wires 4 of the two lighting components are electrically conductively connected to one another in pairs by the electrical connector 5.

[0058] Figure 3 shows a schematic basic representation of a view of a coupling 2 of an embodiment of a system according to the invention. The coupling 2 has a coupling base 21 and two coupling side walls 22 extending away from the coupling base 21 along the vertical direction Z. The coupling side walls 22 have in each longitudinal section of the coupling 2 an upper end 25 and a lower end 24, with which they rest on an associated upper or lower vertical guide section of the respective support rail 1, 10 in the operating state, as shown in Figure 2a. The boundary between the first longitudinal section and the second longitudinal section of the coupling 2 shown is indicated by the indicator 201 shown in the enlarged detail.The first longitudinal section extends from this indicator 201 to the first longitudinal end, which in the illustration according to Figure 2 is the right longitudinal end of the coupling 2. The second longitudinal section extends from the indicator 201 along the longitudinal direction X to the second longitudinal end, which in the illustration according to Figure 3 is the left longitudinal end of the coupling 2. The coupling 2 has, facing each longitudinal end, on its coupling base 21, a centering projection 211, 212 which corresponds to a centering projection 211, 212 in the second longitudinal end section of the second support rail 10 orin the first longitudinal end section of the first support rail 1 arranged end section of the current conducting rail 3 provided therein, so that the respective projection 111, 212 can engage in a corresponding receptacle 122 of the respective current conducting rail 3 in order to reliably align the current conducting rail 3 relative to the coupling 2 and thus also relative to the connector 5 fixed thereto. In addition, the coupling 2 has transverse insertion bevels 223 at each of its longitudinal ends so that it can be inserted more easily into the respective longitudinal end of the respective support rail 1, 10. Each of the coupling side walls 22 has a transverse coupling projection 23 which extends both in the first longitudinal section and in the second longitudinal section of the coupling 2.The transverse coupling projection 23 is spaced from the upper and lower ends of the two longitudinal sections along the vertical direction Z and is arranged, with respect to the vertical direction Z, above the upper end 25 of the coupling side walls 22, with which the coupling side walls 22 in the respective longitudinal section bear against a corresponding vertical guide section of the support rail 1, 10, as can be seen, for example, from Figure 2a. The transverse coupling projection 23 is further formed by a wall section 220 of the respective coupling side wall 22, which runs above the aforementioned vertical ends 25 of the two longitudinal sections.In general, the wall section 220 which forms the transverse coupling projection 23 preferably extends over a defined vertical extension area with a defined vertical upper and vertical lower end, wherein this wall section 220, in addition to the transverse coupling projection 23, further forms a first transverse guide section in the first longitudinal section of the coupling 2 and a second transverse guide section in the second longitudinal section of the coupling 2, wherein in the operating state an associated transverse support rail projection 13 bears against each of the transverse guide sections, as is explained in more detail below with reference to Figure 4. The vertical extension of this wall section 220 is generally preferably limited to a vertical extension length which is less than 40%, in particular less than 30%, in particular less than 20% of the total vertical extension length of the coupling 2.Furthermore, the wall section 220 generally preferably extends exclusively in such a vertical extension region which, starting from the vertically uppermost end of the coupling 2, extends downwards over less than 40%, in particular less than 30% of the vertical extension length of the coupling 2. It can also be seen from Figure 3 that each of the coupling side walls 22 has a gap 26 with a defined vertical length in each of its longitudinal sections, wherein the coupling side walls 22 can be compressed at the level of the gap 26 by a vertical compression force, shortening the vertical length of the gap 26.In addition, each coupling side wall 22 in each longitudinal section of the coupling 2 has a recess 27 which, in the operating state, overlaps with a recess provided in the associated support rail side wall 12 of the respective support rail 1, 10 in which the respective longitudinal section of the coupling 2 is arranged. The recesses 27 are explained in more detail with reference to Figures 5 and 6. The enlarged view also shows geometries of the coupling 2 which serve to guide a scratch spring of the coupling 2 which is not shown in the illustration shown, but is encompassed by the coupling 2 and is mechanically fixed to its coupling body and which has two spring sections, wherein in the operating state one of the spring sections of the scratch spring presses against one of the two support rails 1, 10.To fix the scraper spring, a bearing 283 is provided on the inside of each coupling side wall 22, which can be seen for example in Figures 5 and 6, and the two spring sections of the scraper spring can each penetrate through a passage 282, which is provided for them in one of the longitudinal sections of the coupling 2, through the respective side wall 22, wherein the side walls 22 each form a stop 281 for limiting a deflection of the respective spring section of the scraper spring.

[0059] Figure 4, comprising Figures 4a, 4b, 4c and 4d, shows sections of the first and second support rails 1, 10 and the coupling 2 connecting these two support rails 1, 10 to one another in various schematic diagrams. Figure 4a shows an external view of the support rails 1, 10 with the coupling 2 arranged in their guides. Figure 4b shows an oblique view with reference to section AB shown in Figure 4a, and Figure 4c shows a view of this section AB from above. Figure 4d shows a side view of the two support rails 1, 10 from the outside.From Figures 4a, 4b, 4c and 4d it can be seen that the first support rail 1 forms a transverse support rail projection 13 with each of its support rail side walls 12 within its first longitudinal end section and that the second support rail 10 forms a transverse support rail projection 13 with each of its support rail side walls 12 in its second longitudinal end section. In the operating state, the transverse support rail projections 13 of the first longitudinal end section of the first support rail 1 press transversely against a respectively associated transverse guide section of the coupling 2, which is provided in the first longitudinal section of the coupling 2, and the transverse support rail projections 13 of the second longitudinal end section of the second support rail 10 press against a respectively associated transverse guide section of the coupling 2, which is provided in the second longitudinal section of the coupling 2.The transverse guide sections of the coupling 2 are all formed by the explained wall section 220 of the coupling 2. This wall section 220 further forms the transverse coupling projections 23 of the coupling 2, wherein each of these transverse coupling projections 23 is formed by one of the two coupling side walls 22. These transverse coupling side wall sections press against a respective associated transverse guide section of each of the two support rails 1, 10. The transverse guide section of the support rails 1, 10 and the transverse support rail projections 13 are each formed by a wall section 220 of the respective support rail side wall 12, which is provided above the upper vertical guide section, against which the explained upper end 25 of the respective longitudinal section of the coupling 2 rests in the operating state.The aforementioned wall section 220 is formed by the described indentation 121, in this case by the indentation base of the indentation 121. The described wall section 220, which forms the transverse support rail projection 13 and the transverse guide section of the respective support rail 1, 10, is arranged above a wall section 220 of the respective support rail side wall 12, which forms the upper and lower vertical guide section of the respective support rail side wall 12 and which runs essentially flat and perpendicular to the transverse direction Y.The wall section 220 of the coupling 2, which forms the transverse guide sections of the coupling 2 and the transverse coupling projection 23, is substantially flat and perpendicular to the transverse direction Y, being connected by a curved wall section 221 to a wall section 220 of the respective coupling side wall 22, which is substantially flat and perpendicular to the transverse direction Y and which connects and forms the upper and lower ends 24, 25 of the two longitudinal sections of the coupling 2 provided in the respective longitudinal section of the coupling 2.

[0060] Figure 5, comprising Figures 5a and 5b, and Figure 6, comprising Figures 6a and 6b, show an embodiment of a system according to the invention, on the basis of which embodiments of a method according to the invention are also explained. In the described embodiment, each of the support rail side walls 12 has a support rail side wall section which forms a U-shaped receptacle 122, as can be seen in Figure 2a. In the operating state, this support rail side wall section thus surrounds a coupling side wall 22 assigned to the respective support rail wall transversely on both sides. The support rail side wall section and the assigned coupling side wall 22 each have a recess 17, 27. The recess 27 provided in the coupling side wall 22 overlaps in sections with the recess 27 in the support rail side wall 12 or the recess 17 provided in the support rail side wall section.Figure 5 shows a view of a specific side of the coupling 2 and the support rails 1, 10 from the inside, and Figure 6 shows a view of the other side. Figure 5 therefore shows a first coupling side wall 22 and a first support rail side wall 12 from the inside, while Figure 6 shows a second coupling side wall 22 and support rail side wall 12. The overlap of the cutouts 17, 27 is designed differently on the two sides shown. On the side shown in Figure 5, an edge 271 which borders the cutout 27 provided in the coupling side wall 22 towards the first longitudinal end of the first support rail 1 or limited to the second longitudinal end of the second support rail 10, which is located within the longitudinal extension area of ​​the recess 17 which is provided in the support rail side wall 12 of the respective support rail 1, 10.The edge 171, which delimits the recess provided in the support rail side wall 12 at its end facing away from the first longitudinal end of the first support rail 1 or the side facing away from the second longitudinal end of the second support rail 10 with respect to the longitudinal direction X, can also be seen in Figure 5. This edge 171 of the recess 17 provided in the support rail side wall 12 lies within the longitudinal extension region of the recess 27 provided in the coupling side wall 22. As can be seen from Figure 5b, starting from the operating state, the first support rail 1 can be easily detached from the coupling 2 by inserting a tool, in this case a screwdriver 200, into the overlapping area of ​​the recesses 17, 27 and then turning it so that it generates a pressing force between the indicated edges 171, 271 of the recesses 17, 27 in the first support rail 1 or the first longitudinal section of the coupling 2.6, the cutouts 17 and 27 of the support rail side wall 12 of the coupling side wall 22 also overlap, but on this side the edge 271 of the cutout 27, which delimits the cutout 27 provided in the coupling side wall 22 along the longitudinal direction X at its end pointing away from the second longitudinal end of the second support rail 10 or the end pointing away from the first end of the first support rail 1, lies within the longitudinal extension region of the cutout 17 provided in the corresponding support rail side wall 12, and the edge of this cutout 17 provided in the support rail side wall 12, which delimits this cutout 17 along the longitudinal direction X at its end facing the second longitudinal end of the second support rail 10 or the end pointing away from the first end of the limited at its end facing the first longitudinal end of the first support rail 1, within the longitudinal extension area of ​​the recess 27 provided in the coupling side wall 22.Thus, to generate the operating state, a final movement of the support rails 1, 10 towards one another can be achieved by inserting a tool, for example the screwdriver 200 shown in Figure 6b, into the overlapping area of ​​the recesses 17, 27 and then generating such a force between the edges 171, 271 that the support rails 1, 10 are moved towards one another or the support rails 1, 10 can be moved along the longitudinal direction X as far as the stop 29 provided for them in each case, which is formed by the coupling side wall 22. The provision of such a stop 29 in the coupling 2, against which the respective support rails 1, 10 are moved by means of the tool by applying a force between the edges 171, 271 as described, is generally advantageous according to the invention.
