[0003] Installation-optimized system for the realization of a light strip

[0004] The invention relates to a system for realizing a luminaire which is elongated in a longitudinal direction, as well as to a luminaire produced by means of such a system, and to a method for realizing a luminaire component or 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. If required, the support rail base and support rail side walls can have contours or recesses 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 thus 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 apart from cutouts 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 to one another 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 typically 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 bears against a respective one of the support rail side walls assigned to it.

[0006] The support rail is usually fastened to the building structure via its support rail base. 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 enclosed without interruption 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 produced 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.Typically, the retaining spring is firmly connected to the mounting body and has retaining projections that can be elastically deflected in the transverse direction. The transverse direction, when referring to the mounting body, refers to the operating state of the system. The support rail retaining anchors are preferably designed as projections.

[0007] To realize a generic luminaire, supply lines are usually provided which are arranged in the interior of the support 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 its two 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 portion 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 typically has a plurality of channels arranged next to one another along an alignment 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 alignment direction runs perpendicular to the longitudinal direction. In one embodiment, the alignment 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.At least one conductor wire is arranged in each of at least some of the channels, in particular exactly one conductor wire or exactly two conductor wires, which are held spaced apart from one another in the respective channel. At least one longitudinal end of the current-carrying rail is 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 conductor wires. The conductor 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.

[0008] 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.

[0009] 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.

[0010] 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 current guide rails and the electrical connector are fixed in their position relative to one another by determining the position of the support rails of the luminaire components relative to one another by means of the coupling. Thus, a luminaire of the respective system comprises a plurality of support rails and, in particular, a plurality of mounting bodies and / or current guide rails or a plurality of luminaire components, which are each connected to one another as explained.

[0011] 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 and 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.

[0012] A difficulty that arises when realising a light strip or .a luminaire that is very elongated in the longitudinal direction, is that the components of the system are usually first put into a pre-assembled state in which a number of support rails are arranged one behind the other in the longitudinal direction, as explained, with two support rails arranged one behind the other in the longitudinal direction being connected to one another by a coupling, and in which a current conducting rail is already arranged in each of the support rails, with two current conducting rails that are adjacent in the longitudinal direction being connected to one another by an electrical connector which connects the conductor wires arranged in them in pairs, so that one of the conductor wires that is arranged in one of the two adjacent current conducting rails is connected by the electrical connector to one of the conductor wires that is arranged in the other of the two adjacent current conducting rails.Starting from this pre-assembly state, in which the support rails are usually already fixed to the ceiling of a room, for example, suspended from it or screwed directly to it, further steps are required to realize an operating state of the system, which the components assume when a luminaire is implemented with the system. The description of the operating state refers to the specific arrangement of the components explained with reference to the operating state.Based on the operating state, it is necessary, for example, to bring a feed device into contact with the conductor wires of the current conducting rail and / or to arrange a mounting body on the open side of one of the support rails in such a way that a contact device arranged on it is electrically connected with its contacts to the conductor wires arranged in the current conducting rail provided in the respective support rail to which the mounting body with the contact device is fastened. Firstly, an installer or a robot-like automated installation device must recognize a certain longitudinal position at which the feed device or the mounting body can be inserted into the arrangement of support rails already existing in the pre-assembled state. In addition, the installer or the installation device must recognize the rotational position in which the feed device or the mounting body can be inserted.the mounting body is to be aligned with respect to a vertical axis relative to the mounting rail. Because of the elongated design of the mounting rail and current conducting rail, the mounting body or the feed-in device is usually arranged in at least two different positions relative to the mounting rail and can be inserted into the rail along the vertical direction, which are spaced apart by 180°. However, since in the event of incorrect positioning the feed-in device with its feed-in contacts supplies a line wire which is not intended for this purpose or the contact device with its contacts rests on a line wire which is not intended for this purpose, such incorrect contact can have considerable negative consequences, including failure of the entire system and / or life-threatening injuries. To avoid this, the contact sides of the feed-in device or the current conducting rail are usuallyContact device and the access side of the current guide rail are equipped with coding, so that if the feed-in device or contact device is incorrectly placed on the current guide rail, the contacts or feed-in contacts cannot be brought into contact with the line wires or can only be done with considerable force. In such a case, however, the correct position must always be determined by an installer or an installation facility using trial and error, which is time-consuming on the one hand and, due to the often complex and particularly elongated design of the mounting body, contact device and feed-in device, is not without problems. In addition, longitudinal positions must be tried out erratically during installation in which the respective component can be positioned relative to the mounting rail in such a way that its respective contacts orFeed contacts can be brought into contact with the respective conductor wires, and additional components, such as additional mounting elements with additional contact devices, can be mounted on the mounting rail or the mounting rail arrangement. This erratic determination of a possible longitudinal position often results in gaps that ultimately arise between components, such as mounting elements, being filled with dummy modules, the length of which is sawn or cut to size as required. This is labor-intensive and often results in visually undesirable effects.

[0013] The present invention is based on the object of providing a system for realizing a luminaire which is elongated in a longitudinal direction, an elongated luminaire and / or a method for realizing a luminaire which is elongated in a longitudinal direction or for realizing an arrangement of luminaire components, which at least partially eliminates at least one disadvantage of generic systems, luminaires and / or methods.

[0014] 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 at least one longitudinally elongated support rail with a U-shaped cross-section, 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. The system further comprises at least one longitudinally elongated current conducting rail, which has channels arranged next to one another in an array direction running perpendicular to the longitudinal direction, which are elongated in the longitudinal direction and open on an access side of the current conducting rail. At least one longitudinally elongated conducting wire is arranged in each channel.In a pre-assembled state of the system, one of the current conducting rails is arranged in the interior of each of the support rails and fixed to this support rail, wherein its access side is accessible from the interior of the support rail. In at least some embodiments, the system further comprises a coupling, wherein each of the support rails has a guide for the coupling, wherein the guide is formed in particular at least partially by the support rail side walls of the respective support rail. Two support rails, which in the pre-assembled state are arranged one behind the other along the longitudinal direction, are fixed to one another by the coupling. The system further comprises at least one mounting body which, in an operating state of the system, is arranged on the open side of the support rail and fixed to the support rail and which, together with the support rail, encloses an interior space provided for accommodating electrical components.In the operating state, the support rail and the current conducting rail - if a plurality of support rails and a plurality of current conducting rails as well as at least one coupling are provided - these components have the same relative position to one another as they have to one another in the pre-assembled state. A contact device is arranged on the mounting body, which is electrically conductively connected to an electrical functional element and which has contacts on one contact side which, in the operating state, are arranged in at least some of the channels of the current conducting rail and contact the conductor wire arranged therein. The system furthermore has a feed device which has a fastening device and, on one contact side of the feed device, feed contacts which, in the operating state, are arranged in at least some of the channels of the current conducting rail and electrically conductively contact the conductor wire arranged therein.The fastening device is preferably designed to correspond to an inner contour of the support rail. In general, the fastening device is designed to fix the feed device to the support rail in the operating state relative to the support rail. The contact device and the feed device can each be inserted vertically into the interior of the support rail from an incorrect position in the pre-assembled state or alternatively from a contacting position from the open side of the support rail until their respective contact side is arranged on the access side of the current conducting rail. The incorrect position and the contacting position of the feed device or contact device only differ in that the contact device or feed device is rotated by 180° about a vertical axis in the incorrect position compared to the contacting position. Otherwise, the contact device orThe feed-in device, apart from its rotational position about the vertical axis, occupies the same relative position relative to the support rail in the contacting position and the incorrect position as it is arranged in the operating state. The operating state can only be achieved starting from the contacting position by inserting the contacting device or feed-in device along the vertical direction into the support rail, without the feed-in device or contact device having to be rotated about the vertical axis beforehand. On the other hand, the contact device or feed-in device starting from the incorrect position cannot be fed along the vertical direction onto the current conducting rail already arranged in the support rail in the pre-assembled state in such a way that the operating state can be achieved without it having to be rotated about the vertical axis beforehand so that it occupies the contacting position.According to the invention, the support rail has on an inner side of at least one of its support rail side walls a directional marking pointing in a specific direction along the longitudinal direction, which can be detected by a detection device, and the contact device and / or the feed device has a corresponding directional marking which can be detected by the detection device, wherein in the contacting position and the operating state the corresponding directional marking and the directional marking point in the same direction and in the incorrect position the corresponding directional marking points in a direction opposite to the specific direction along the longitudinal direction.By arranging the directional marking on at least one of the support rail side walls and arranging a corresponding directional marking on the contact device and / or the feed device, which can each be detected by a detection device, the realization of a luminaire by means of the system according to the invention can be considerably simplified. This is because the directional marking and corresponding directional marking can be detected before the contact device or feed device is inserted into the support rail along the vertical direction, so that contact devices, in particular with the mounting body or feed device attached thereto, can be inserted directly into the support rail in the correct rotational position and thus no first attempt is made to insert the contact device orThe feed device is to be brought into contact with the conductors in an initially randomly selected rotational position. If the rotational position is incorrect and the attempt is thus unsuccessful, the contact device and feed device must first be removed from the support rail, after which a new attempt must be made. The direction marking and the corresponding direction marking are designed analogously, so that a detection device can particularly easily detect the parallel or antiparallel alignment of the direction marking and the corresponding direction marking.For example, the directional marking and the corresponding directional marking can be designed in the manner of an arrow or in the manner of a triangle which tapers to a point in exactly one direction along the longitudinal direction and has its base on the other side, relative to the longitudinal direction, or generally as a geometric body which tapers to a point in exactly one direction along the longitudinal direction and has a wide end in the opposite direction along the longitudinal direction. In this case, the corresponding directional marking and the directional marking are always generally advantageously designed identically, so that their parallelism or antiparallelism can be detected particularly easily.

[0015] In one embodiment, the direction marking and the corresponding direction marking are each provided on a side with its surface normal pointing perpendicular to the longitudinal direction. It has been found that such a side of the support rail side wall or contact device or feed-in device can be detected particularly easily by means of the system when an elongated luminaire is implemented, in particular by detecting a transverse side diagonally from below. For example, a detection device can be provided for this purpose which is positioned transversely laterally below an already mounted support rail in which a current conducting rail is arranged and which lights up green when the direction marking and corresponding direction marking are aligned parallel, i.e. when arranged pointing in the same direction, and lights up green when they are arranged anti-parallel, i.e.pointing in the opposite direction, lights up red. It has been found to be particularly advantageous to provide the direction marking on a side of the support rail side wall with its surface normal pointing along the transverse direction, in particular on the side of the support rail pointing towards the opposite support rail side wall, and to provide the corresponding direction marking of the contact device on a side of the contact device with its surface normal pointing along the transverse direction and / or to provide the corresponding direction marking of the feed device on a side of the feed device with its surface normal pointing along the vertical direction.It should be taken into account that the feed device for fastening to the support rail often has to be actuated on its transverse sides, so that the corresponding direction marking is particularly preferably provided on a side of the feed device with its surface normal pointing along the vertical direction, in particular on its vertical underside, since this side is always particularly easy to detect during the assembly process for the realization of the luminaire.

[0016] 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 forms part of the guide of the support rail, the system having a coupling which has a coupling body with a U-shaped cross-section, which is formed by a coupling base and two coupling side walls. 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 transversely on both sides. The directional marking is preferably provided on a side of the support rail side wall section facing the transverse center. This makes it particularly advantageous to recognize the directional marking even when the coupling is installed.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. Preferably, the U-shaped base of the U-shaped receptacle forms a lower vertical guide section of the support rail guide. 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.

[0017] In one embodiment, the system comprises a coupling which has a coupling body with a U-shaped cross-section which is formed by a coupling base and two coupling side walls, wherein, as explained above, each of the coupling side walls is preferably received in a U-shaped receptacle formed by the respective support rail side wall in the operating state. Preferably, a coupling marking designed analogously to the directional marking is provided on at least one of the coupling side walls and is recognizable from an inner side of the coupling. The inner side of the coupling designates the side which is enclosed by the coupling side walls and the coupling base, so that the inner side of one coupling side wall points towards the opposite coupling side wall.The provision of such a coupling marking can result in even improved detectability, whereby it can be ensured even more reliably whether the contact device or feed device is arranged in the incorrect position or in the contacting position. The coupling marking can be formed, for example, by an imprint, a deformation or a punching in a coupling side wall. In one embodiment, the mounting body is delimited along the transverse direction by two mounting body side walls, wherein the mounting body has a mounting body marking designed analogously to the corresponding marking on an outer side of at least one of its mounting body side walls. This can correspondingly lead to improved detectability and thus determination of the incorrect position or contacting position. By providing a mounting body marking orBy providing a coupling marking designed analogously to the marking, at least practically identically designed markings can be provided on different components for the purpose of detection, whereby a particularly high number of these markings can be recognized from any position, whereby the detection of incorrect positions or contact positions is particularly improved.

[0018] In one embodiment, a plurality of identical directional markings are arranged one behind the other in the longitudinal direction and at a distance from one another. This can also contribute to better detectability. The directional markings are preferably arranged over a longitudinal region of the support rail which extends over at least 70%, in particular at least 80% of a longitudinal extension length of the support rail. This can ensure that one of the directional markings can be detected over a particularly large longitudinal region of the support rail. In one embodiment, the directional markings are arranged in groups which are arranged one behind the other along the longitudinal direction, with a separating mark being provided on the support rail between each two groups of directional markings. An identical distance is provided between each two adjacent separating markings.The separation markings can be used particularly advantageously for dividing the length of the support rail and thus for easily determining the correct positioning of a mounting body or a contact device or a feed-in device with regard to the longitudinal direction or longitudinal position. This can particularly simplify the implementation of a luminaire that is particularly elongated in the longitudinal direction, in particular comprising support rails with a length of at least 3 m, in particular comprising a plurality of such support rails. In one embodiment, the mounting body has a longitudinal extension length that corresponds to the distance or is an integer multiple of the distance. Thus, when the mounting body is arranged with one longitudinal end at the separation marking, the correct longitudinal position of the mounting body can always be reliably achieved.Particularly preferably, the system comprises a plurality of mounting bodies that differ only in their longitudinal extension length, in that their longitudinal extension length corresponds to a product of a different integer and the distance. Thus, while various mounting bodies with different lengths can be provided, each of which can be used for a different purpose depending on their length, all of these mounting bodies can be positioned particularly easily in a correct longitudinal position relative to the support rail due to the provision of the separation markings.

[0019] Generally speaking, each current conducting rail preferably has a holding device with which it is fixed to a holding region of the support rail assigned to it. The holding region is preferably formed by the advantageously provided indentation in the support rail as explained here. Generally speaking, the indentation extends continuously along the longitudinal direction of the support rail over the entire longitudinal extent of the support rail. In one embodiment, the electrical connector has a holding device with which it is fixed to the coupling. In one embodiment, the holding device of the respective current conducting rail has a plurality of holder sections which are spaced apart from one another in the longitudinal direction and are distributed over at least 80% of a total length of the current conducting rail.Preferably, in the operating state, all of the holding sections are each arranged on a section of the holding device of the support rail and contribute to fixing the current conducting rail relative to the support rail. Each of the holding sections can be designed in one piece or in multiple parts, in particular can comprise partial sections. It is important that two holding sections adjacent in the longitudinal direction are spaced apart from one another by a certain distance in the longitudinal direction. In one embodiment, the support rail has at least one interval marking on the inside of at least one of its support rail side walls, wherein in the pre-assembled state, and of course also in the operating state, the interval marking extends over the same longitudinal region over which the distance between two of the holding sections is arranged. The interval marking can accordingly be detected by a recognition device.The interval marking provided on the support rail thus specifically indicates the longitudinal range in which the distance between two holding sections of the current conducting rail is located. This means that the detection device can also detect the longitudinal position in which the feed-in device can be positioned on the support rail so that it can then be inserted vertically into the support rail and fixed to the support rail using its fastening device. This is because of the distance between the holding sections of the current conducting rail and the resulting free space, the fastening device can use this free space particularly advantageously to fix the feed-in device relative to the support rail.In the operating state, the feed device with its fastening device is generally preferably arranged within the longitudinal region, wherein the fastening device engages behind the holding region of the support rail and thus fixes the feed device relative to the support rail. In a general manner, the holding region can be designed as a holding projection that is formed on the inside of each support rail side wall.

[0020] In one embodiment, a first interval marking is provided in a first longitudinal end region of the support rail and a second interval marking is provided in a second longitudinal end region of the support rail, wherein, in the operating state, the feed device is arranged within a longitudinal extension of one of the first or second interval markings. By arranging the feed device in the longitudinal end region, the feed device can be particularly advantageously accessible. Furthermore, incorrect detection of the interval marking can be particularly advantageously avoided since the interval marking is preferably provided only in the two end regions.

[0021] 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 can serve to correspondingly fix the current conducting rail or mounting element or coupling.The indentations of the support rail side walls can in particular form the holding area of ​​the support rail.

[0022] In one embodiment, the corresponding directional marking encompassed by the feed device is provided on a side of the feed device facing away from the contact side. The contact side is preferably a side of the feed device which, in the operating state, points vertically upwards with its surface normal, whereas the directional marking is provided on the vertically downward-pointing underside of the feed device. In one embodiment, in the operating state, the feed device is arranged within a longitudinal extension of the mounting body and at a distance in the longitudinal direction from the contact device which is arranged on the mounting body. This can particularly advantageously ensure a space-saving arrangement without the feed device and contact device hindering each other.

[0023] In one embodiment, the coupling is made from a formed sheet metal. In one embodiment, the support rails are made from a formed sheet metal. In one embodiment, the system comprises at least one mounting body which is made from a formed sheet metal. Furthermore, it should be generally pointed out that any longitudinal end section of a component always comprises one of the longitudinal ends of the component and extends from the longitudinal end to the longitudinal center of the component. Generally speaking, the longitudinal end section extends from the respective longitudinal end over less than 40%, in particular less than 30%, in particular less than 20% of the longitudinal extent of the component.

[0024] The invention further relates to a method for producing a luminaire component which is elongated in a longitudinal direction and which has an elongated support rail with a U-shaped cross-section, 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.

[0025] As explained, the support rail side walls and support rail base together delimit a support rail interior. A longitudinally elongated current conducting rail is arranged in the support rail interior and fixed to the support rail. The current conducting rail has channels arranged next to one another in a row direction and open on an access side of the current conducting rail, with at least one conducting wire arranged in each channel. The access side of the current conducting rail and thus the conducting wires are accessible from the support rail interior.

[0026] In one embodiment of the method according to the invention, to produce the luminaire component, a mounting body on which an electrical functional element and a contact device are arranged is arranged with the contact device on the open side of the support rail at a vertical distance from the support rail. During or after this, a directional marking provided on the support rail and a corresponding directional marking provided on the contact device are detected and aligned parallel to one another. The mounting body is then moved vertically towards the support rail by a purely translational movement, and in the process the contact device is guided to the current conducting rail. The contacts of the contact device are then brought into contact with the conductor wires arranged in the current conducting rail.After the direction marking and the corresponding direction marking have been aligned, the contact device is brought with its contact side to the access side of the current guide rail, after which its contacts are introduced into the channels of the current guide rail and brought to the line wires in an electrically conductive system.

[0027] In one embodiment of the method according to the invention, a feed device designed to supply the line wires with electrical energy is arranged on the open side of the support rail at a vertical distance from the support rail. During or after this, a directional marking provided on the support rail and a corresponding directional marking provided on the feed device are detected and aligned parallel to one another. The feed device is then moved vertically towards the support rail by a purely translational movement and is guided to the current conducting rail. The feed contacts of the device are then brought into contact with the line wires arranged in the current conducting rail.Thus, the feed device is first moved with its contact side to the access side of the current conducting rail, after which its feed contacts are guided into the channels of the current conducting rail and brought into electrically conductive contact with the conducting wires, analogously to that explained with reference to the previously described embodiment in connection with the contacts of the contact device.

[0028] The embodiment of the method according to the invention can make it particularly easy to produce a lighting component. This is because during the course of the method the directional marking on the support rail is detected and compared with the corresponding directional marking on the feed device or contact device, the corresponding directional marking being aligned parallel to the directional marking, i.e. the directional marking and the corresponding directional marking point in the same direction, which reliably ensures that the contact device or feed device is inserted into the support rail in a contacting position in which its respective contacts or feed contacts can be inserted into the channels of the current conducting rail and can be brought into electrically conductive contact with the conductor wires for whose contact they are respectively intended.Accordingly, the method according to the invention can be used to easily produce a lighting component which comprises a feed device or a contact device which, with its feed contacts or contacts, rests in electrically conductive contact against the conductor wires of the current conducting rail and which is fixed relative to the support rail, in the case of the feed device by means of its fastening device, in the case of the contact device by means of the mounting body. When combining the explained embodiment of the method according to the invention, a lighting component can be easily produced which has a feed device and a contact device which, with their respective contacts or feed contacts, rests in electrically conductive contact against the conductor wires of the current conducting rail. By producing the lighting component, the method according to the invention correspondingly also enables the production of a light.For example, the luminaire may comprise only one luminaire component, for example a luminaire component on which at least one or more mounting bodies are provided, each with a contact device, which are arranged in electrically conductive contact with the conductor wires provided on the current guide rail, wherein at least one of the mounting bodies has a lighting module as an electrical functional element.

[0029] The invention further relates generally to a luminaire which is produced by means of a system according to the invention or by means of a method according to the invention. The luminaire comprises at least one support rail with a U-shaped cross-section, as sufficiently explained here. The luminaire further comprises a current conducting rail with channels in which conducting wires are arranged, as sufficiently explained here. The current conducting rail is arranged in the interior of the support rail and fixed to the support rail, and its access side is accessible from the interior of the support rail. The luminaire comprises a plurality of mounting bodies which are arranged on the open side of the support rail and fixed to the support rail and which, together with the support rail, enclose an interior space provided for accommodating electrical components.A contact device is arranged on each mounting body, which is electrically connected to an electrical functional element and which has contacts on one contact side, which are arranged in at least some of the channels of the current guide rail and contact the conductor wire arranged therein. The luminaire also has a feed device, which is fixed to the support rail and has feed contacts, which are arranged in at least some of the channels of the current guide rail and contact the conductor wire arranged therein.The support rail has on an inner side of at least one of its support rail side walls a directional marking pointing in a specific direction along the longitudinal direction, which can be detected by a detection device, and the contact device and / or the feed device have a corresponding directional marking which can be detected by the detection device, wherein the corresponding directional marking and the directional marking point in a same direction.

[0037] In Figure 1, in a schematic diagram for explaining the basic design of an elongated lamp 100 according to the invention, a

[0038] 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.

[0039] Figure 2, comprising Figures 2a, 2b, 2c, 2d, 2e, 2f and 2g, shows, for the purposes of explanation, 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, which provides a frictional connection, 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 relative movement between the support rail 1 and the coupling 2. Figures 2b, 2c, 2d, 2e, 2f and 2g explain the transition in the operating state between two support rails 1, 10 arranged one behind the other and fixed to one another in the operating state, based on 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 view of Figures 2b and 2c together, it can be seen that a current conducting rail 3 with channels 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 a conducting wire 4 is arranged in each of the channels and 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.

[0040] Figure 3, comprising Figures 3a and 3b, shows various detailed views of components of an embodiment of the system according to the invention in various schematic principle representations. Figure 3a shows a support rail 1, in the interior of which a current conducting rail 3 and a feed-in device 7 are arranged. The state shown here corresponds to the operating state of the system. The feed-in device 7 is additionally shown in isolation in Figure 3a for explanatory purposes. It can be seen from Figure 3a that one of the support rail side walls has a directional marking 14 on its inside and that the feed-in device 7 has a corresponding directional marking 71 on its underside pointing along the vertical direction Z.Direction marking 14 and corresponding direction marking 71 are each designed in an analogous manner, namely in the manner of an arrow which points in a specific direction along the longitudinal direction X. It can be seen from Figure 3a that the feed device 7 can be aligned in a particularly simple manner relative to the support rail 1, based on its rotational position about a vertical axis, such that its corresponding direction marking 71 points in the same direction as the direction marking 14 of the support rail 1, so that it can be inserted into the interior of the support rail by a simple, purely translational movement from below vertically upwards until its contact side rests on the current conducting rail 3 and its feed contacts are brought into engagement with the channels of the current conducting rail 3 and rest against the conductor wires arranged therein.It can also be seen from Figure 3a that the feed device 7 has a fastening device 72 which comprises retaining springs, which is generally advantageous according to the invention. In addition, the feed device 7 has, generally advantageous according to the invention, a locking element 73 which, in a first vertical position, blocks a deflection of the retaining springs of the fastening device 72 and, in a second vertical position, permits such a deflection, which is generally advantageous according to the invention. In the illustration according to Figure 3a, the locking element 73 is in the locking position.When it is pulled downwards from this locked position, the retaining springs of the fastening device 72 are deflectable, in this case deflectable in the transverse direction Y, so that the feed device 7 can be introduced into the interior of the support rail in a simple manner by a purely translational movement along the vertical direction Z until its fastening device, i.e. the retaining springs of the fastening device 72, engage behind the undercut or holding area of ​​the support rail 1 formed by the indentation 121. It can also be seen from Figure 3a that an interval marking 16 is also provided on the inner side of the support rail side wall shown.This interval marking 16 indicates a longitudinal range within which the feed device 7 can be inserted into the support rail 1 without any obstacle by a purely translational movement along the vertical direction Z such that its fastening device 72 engages behind the holding area of ​​the support rail 1 and thus ensures that the feed device 7 is fixed to the support rail 1. For explanatory purposes, Figure 3b shows the current conducting rail 3 in a position which is offset by a purely translational movement along the vertical direction Z compared to the position in Figure 3a, the feed device 7 simultaneously being shown in a position relative to the current conducting rail 3 in which its feed contacts engage with the channels of the current conducting rail 3 and contact the conductor wires 4 arranged therein.From Figure 3b it can be seen that the current conducting rail 3 has holding sections 31 over a considerable area of ​​its longitudinal extent, wherein two holding sections 31 adjacent along the longitudinal direction X are spaced from one another by a distance 32. Each of the holding sections 31 has two subsections which are arranged one behind the other along the longitudinal direction X. The interval marking 16 indicates the area between two holding sections 31. As can be seen from a combination of Figures 3a and 3b, the interval marking 16 indicates the distance 32.

[0041] By arranging the feed device 7 within the longitudinal region over which the interval marking 16 extends, it is ensured that its fastening device 72 can engage behind the holding region of the support rail 1 without colliding with the holding sections 31 of the current conducting rail 3. It can also be seen from Figures 3a and 3b that the support rail 1 has a plurality of identical directional markings 14 which are arranged one behind the other at a distance from one another in the longitudinal direction X. This facilitates correct alignment of the feed device 7 or the contact device 8 (explained in more detail below) in every possible longitudinal position along the longitudinal extent of the support rail 1.Furthermore, it can be seen from Figure 3a that the support rail side wall shown has a plurality of separation markings 15 on its inner side, which are arranged one behind the other along the longitudinal direction X, wherein two adjacent separation markings 15 are spaced from one another by an identical distance along the longitudinal direction X and a plurality of directional markings 14 are located between each two separation markings 15. The system comprises a plurality of mounting bodies 6, one of which is shown by way of example in Figure 4. A contact device 8 is arranged on each of the mounting bodies 6, in particular exactly one contact device 8, which is generally advantageous according to the invention.In addition, at least two retaining springs 61 are arranged on each mounting body 6 and are designed to engage behind a retaining projection 123 of the support rail 1, as shown in Figure 2a, in order to hold the mounting body 6 fixed to the support rail 1 in the operating state. The system comprises a plurality of different mounting bodies 6 which only differ in their longitudinal extent. The longitudinal extent of each mounting body 6 corresponds to an integer multiple of the distance between two separation markings 15 or this distance. This can enable particularly simple assembly or implementation of a lighting component or a light 100, since the mounting bodies 6 can each be arranged with their longitudinal ends at the level of one of the separation markings 15, thereby ensuring that the open side of the support rail 1 or the support rail 1 is covered by the provided mounting bodies 6.a support rail arrangement comprising a plurality of support rails 1 arranged one behind the other in the longitudinal direction X can be closed continuously. Figure 4 shows various schematic principle representations of a mounting body 6 with a contact device 8 and a support rail 1 with the inside of one of the side walls. It can be seen from Figure 4 that the support rail 1 has directional markings 14 and that the contact device 8 has a corresponding directional marking 81. It can also be seen that if the mounting body 6 is initially incorrectly aligned due to its considerable longitudinal extent, rotating the mounting body 6 and correctly aligning it relative to the support rail 1 is complicated.However, since corresponding direction marking 81 and direction marking 14 are designed analogously, in this case both as an identically designed arrow, they can be detected particularly easily, so that the mounting body 6 can be arranged directly in a correct rotational position, relative to a vertical axis of rotation, vertically below the support rail 1 and can then be moved towards the support rail 1 by a purely translational movement along the vertical direction Z and the contact device 8 can be introduced into the support rail 1 in such a way that the contacts of the contact device 8 immerse themselves in the channels of the current conducting rail 3 and contact the conducting wires 4 arranged there when the mounting body 6 is held on the holding projections 123 of the support rail 1 via the holding springs 61.It should also be noted that the retaining springs 61, which is generally advantageous according to the invention, can be deflected by actuating elements 610 in such a way that, starting from the operating state, the mounting body 6 can be easily detached from the support rail 1 again. Figure 4 also shows that a plurality of covers 101 are provided on the underside of the mounting body 6, which is generally advantageous according to the invention. Each of the covers 101 can conceal a lighting module, which on the one hand can ensure protection of the lighting module and on the other hand can influence the light emission characteristics of the lighting module in the desired way if the cover 101, which is generally advantageous according to the invention, is designed to direct light and is therefore an optical system.
