Description

[0001] The invention relates to a system for realizing a luminaire according to the preamble of claim 1, as well as to a luminaire and a method for manufacturing such a luminaire. Systems of this type for realizing luminaires of this type are widely known in the prior art and are frequently used for realizing luminaires, in particular elongated luminaires that can illuminate large spaces, e.g., warehouses, factory halls, showrooms, or offices. Such systems comprise at least one longitudinally elongated mounting rail and at least one longitudinally elongated mounting body. When realizing a luminaire using a system of this type, the mounting rail essentially forms the infrastructure of the luminaire, in that the mounting rail is attached to a building element, for example, a ceiling or a wall, and supply lines are provided on the mounting rail.The mounting body is typically then connected to the mounting rail. Light sources and / or other functional elements, such as a control gear, a sensor, a camera, or a radio module, are integrated into the mounting body, so that it incorporates the desired functional elements for the specific room. The mounting body must not only be mechanically connected to the mounting rail, but the light source and / or other functional elements attached to the mounting body must also be electrically connected to the supply lines provided in the mounting rail. Typically, elongated luminaires are created using systems of this type, employing several mounting bodies arranged side by side in a longitudinal direction. At least one of the mounting bodies used is equipped with a light source.It is also known in the prior art to arrange several mounting rails side by side longitudinally, forming a longitudinally elongated mounting rail arrangement, and then to connect a multitude of mounting bodies arranged side by side longitudinally to this mounting rail arrangement. The problem always arises that all mounting bodies of the luminaire must be connected to the supply lines provided in the mounting rail or mounting rail arrangement. The supply lines provided in the mounting rail are connected to a power supply network, so that the electrical supply to the mounting body is ensured by contacting the supply lines.

[0002] In the prior art, various solutions exist to ensure reliable contact between each mounting element and a mounting rail or mounting rail assembly. For example, it is known to provide through-wiring in the mounting rail, along which a contact device is located at a predetermined position in the mounting rail. A contacting device corresponding to this contacting device is provided on the mounting element. When the mounting element and mounting rail are mechanically connected, the contacting device and the contacting device are connected to each other, thus establishing an electrical connection between the supply lines and the light source or other functional element of the mounting element.This allows for the cost-effective provision of a generic system that enables simple and reliable contacting of the mounting body to the supply lines of the mounting rail. However, such a system has the disadvantage that, due to the fixed position of the contact device, the mounting body must be precisely aligned relative to the mounting rail so that its contacting mechanism can be aligned with the contact device when the mounting body is fixed to the mounting rail. Therefore, with such a generic system, it is not possible to choose a mounting body with a high degree of freedom after the installation of a mounting rail infrastructure in a room.However, since the use of rooms changes, and consequently the requirements placed on a luminaire also change, and since technical innovations may arise that should ideally be integrated into an existing mounting rail infrastructure, such a cost-effective system is disadvantageous. This disadvantage was addressed in the prior art by providing systems in which a conductor rail is integrated into a mounting rail, extending along its length. Such a conductor rail typically has channels that are open on one side facing the mounting body and in which the supply lines are arranged.By providing a suitable contacting device on the mounting body, capable of engaging the busbar and contacting the supply lines within it, the mounting body can be positioned along a mounting rail at virtually any longitudinal position, always ensuring electrical contact between the busbar's supply lines and the mounting body. Thus, when a mounting rail infrastructure is used, a busbar extends continuously or with only minor interruptions along the entire length of the mounting rail assembly, ensuring a high degree of flexibility in the use of a once-installed mounting rail infrastructure.However, the manufacture of such a system involves considerable costs, as the production of the busbars and their through-connection from mounting rail to mounting rail is complex, both in terms of manufacturing and the installation of a luminaire of this type using such a system. DE 10 2012 106 165 A1 discloses a luminaire with a housing that has several lamp chambers, each containing a lamp, wherein the housing has an externally accessible busbar via which the luminaire can be supplied with electrical energy. DE 81 36 915 U1 discloses a luminaire with a tubular shade that has an opening through which a busbar arranged in the shade can be contacted to supply the luminaire with electrical energy.From DE 203 07 174 U1 a luminaire with a mounting rail and a mounting body which has lamp sockets for light sources is known, wherein supply lines are arranged on the mounting rail and the lamp sockets are supplied with electrical energy by means of an adapter which is connected to the supply lines.

[0003] The present invention is based on the objective of providing a system for the realization of a luminaire that at least partially eliminates one of the described disadvantages of generic systems.

[0004] As a solution to the problem underlying the invention, the invention proposes a system with the features according to claim 1. The system of this solution according to the invention comprises a longitudinally elongated support rail and a longitudinally elongated mounting body. The mounting body is suitable for being attached to the support rail in an operating position and, in this operating position, together with the support rail, for surrounding the interior of the luminaire around its longitudinal axis. The operating position is the intended position of the system, i.e., the intended relative arrangement of the system elements in which a luminaire according to the invention can be realized. The support rail and mounting body do not necessarily have to completely enclose the interior; in some embodiments, the support rail and mounting body may, for example, have feedthroughs.However, arrangements are also possible, for example, for the realization of sealed luminaires, in which the mounting rail and mounting body completely enclose the interior. In these cases, the term "enclosure" always refers to a circumferential connection around the longitudinal direction. In any case, the mounting rail and mounting body define an interior space with respect to a plane perpendicular to the longitudinal direction. Supply lines are arranged on the mounting rail, preferably located within this interior space in the operating position, and a light source and / or other functional element is arranged on the mounting body, wherein, in the operating position, the light source and / or the other functional element is electrically connected to the supply lines. A system of this type can, for example, have several mounting rails, preferably several identical mounting rails, and several mounting bodies.For example, some of the mounting bodies may be provided with light sources, while others may have additional or alternative functional elements. The system according to the invention may have further features, which have been explained above in connection with generic systems. According to the invention, a current conductor rail with channels is provided on the mounting body. Conductor wires are arranged in these channels, and the channels are open on a side facing the interior in the operating position to allow contact of the conductor wires along the channels from the interior. The current conductor rail and the channels are preferably elongated along the longitudinal direction. In this context, "elongated" means that the extension along the longitudinal direction is at least 1.5 times, in particular at least 5 times, and in particular at least 10 times, the maximum extension length perpendicular to the longitudinal direction.The system further comprises a contact device with two contact sides and a contact assembly provided on the mounting rail, which is electrically connected to the supply lines. In the operating position, a first contact side of the contact device is inserted into the channels and electrically connected to at least some of the conductor wires arranged in the channels, and a second contact side of the contact device is formed correspondingly to the contact assembly. In the operating position, the second side of the contact device is joined to the contact assembly, in particular inserted into it, and conductively connected to the contact assembly, thereby establishing an electrically conductive connection between the supply lines and the conductor wires in the current conductor rail of the mounting body that are contacted by the first contact side.The conductor rail preferably extends over at least 20% of the longitudinal length of the mounting body, in particular over at least 30%, and especially over at least 70% of the longitudinal length of the mounting body. The conductor rail thus ensures variability in the arrangement of the mounting body relative to the mounting rail with respect to the longitudinal direction, since contact between a contact device provided at a fixed position on the mounting rail and the conductor wires in the conductor rail of the mounting body is enabled over at least a substantial portion of the conductor rail's longitudinal extent. The conductor wires of the conductor rail are then connected to the light source of the mounting body and / or other functional elements. For example, the conductor wires can be connected to a control gear, which in turn is connected to the light source.

[0005] The system according to the invention offers significant advantages compared to conventional systems. The present invention is based on the inventors' realization that, to achieve a system that is both cost-effective and highly versatile, it is particularly advantageous to provide mounting bodies that, due to the inclusion of a longitudinal conductor rail, can be positioned variably relative to the mounting rail over a considerable longitudinal section. The inventors have thus departed from the standard approach of requiring a mounting rail infrastructure to enable a versatile system. Instead, the inventors recognized that providing such a mounting rail infrastructure entails considerable costs, which are unnecessary for implementing a system that is typically required.For, typically, it is sufficient to be able to variably position only certain mounting elements in the longitudinal direction of a mounting rail or mounting rail assembly once it has been installed, while arranging a multitude of other mounting elements at positions on the mounting rail determined by the positions of contact devices. Furthermore, the system according to the invention enables the cost-effective implementation of a large-area mounting rail assembly for installing a mounting rail infrastructure, after which, depending on requirements, either cost-effective mounting elements that can only be installed in a specific position within the mounting rail assembly or more expensive mounting elements that can be used variably can be selected.Of course, in one embodiment of the system according to the invention, a mounting rail can also be used on which a conductor rail is provided, in which case this conductor rail can form the contact device and the contact device can be designed to connect the two conductor rails.

[0006] Particularly preferably, the contact device and the conductor rail are designed to correspond to each other such that the contact device, with its first contact side, can be inserted into the channels and electrically connected to the conductor wires in any longitudinal position within a longitudinal section that extends along at least 20%, in particular at least 50%, in particular at least 70% of the longitudinal extension length of the mounting body. This longitudinal section can run continuously along the longitudinal direction or have interruptions, for example by providing a multi-part conductor rail, whereby the conductor rail is preferably formed in one piece.Particularly preferably, the contact device and the conductor rail are configured to correspond to each other such that the contact device, with its first contact side, can be inserted into the channels and electrically connected to the conductor wires over at least 50% of the longitudinal length of the conductor rail. The conductor rail and contact device can be configured such that the longitudinal section runs continuously along the longitudinal direction or such that the longitudinal section has interruptions along the longitudinal direction, but overall has the length specified above as preferred.The described corresponding design of the conductor rail and contact device allows for a particularly high degree of variability, since the mounting body can be arranged in different positions relative to the mounting rail along the length of the longitudinal section, thereby enabling contact between supply lines and the light source or other functional element via the conductor rail, contact device, and contact assembly. For example, the contact device and conductor rail can be designed such that the contact device can be mechanically fixed to the conductor rail and then moved along the longitudinal direction relative to the conductor rail while maintaining this fixation.In another embodiment, the conductor rail and contact device can be designed such that the contact device can be inserted into the conductor rail with its first contact side at various positions along the longitudinal direction, which in particular can be continuous, wherein the insertion also results in a mechanical fixing of the contact device relative to the conductor rail.

[0007] Generally, both contact sides of the contact device are preferably designed as plugs, and the contact device itself is designed as a socket. Designing the contact device as a socket can be particularly suitable for ensuring electrical protection, so that a user or installer does not come into direct contact with the supply lines when touching the contact device. Designing both contact sides of the contact device as plugs can be particularly advantageous, as this allows the first contact side to be easily inserted into the busbar to connect the conductor wires, and the second contact side to be easily inserted into a socket-style contact device to connect the supply lines.

[0008] In one embodiment, an operating device is arranged on the mounting body. For example, the operating device and the busbar can run together in the same longitudinal section. For example, the operating device and the busbar can be arranged one behind the other in the longitudinal direction. Arranging the busbar and operating device one behind the other can enable particularly simple installation of the busbar and operating device and particularly simple contacting of the busbar by means of the first contact side of the contact device. Arranging the operating device and the busbar side by side, i.e., arranging the operating device and the busbar together in the same longitudinal section, can particularly advantageously enable the realization of the longest possible busbar. Particularly preferably, the longitudinal length of the busbar is more than 70% of the longitudinal length of the mounting body.The operating device is preferably arranged on a transverse or vertical side of the busbar and runs along the same longitudinal section as the busbar. When the operating device is arranged on a vertical side of the busbar, it is preferably positioned vertically below the busbar, while in the operating position the contact device is provided vertically above the busbar, thus enabling particularly simple contact between the busbar and the contact device via the contact mechanism.

[0009] Preferably, the first contact side has a PE contact to protect a user against electric shock. In the operating position, this contact is arranged laterally next to the busbar and presses against the mounting body to ensure contact with the mounting body. In this way, the mounting body can be connected directly to the contact device via the first contact side and thus via the contact mechanism, and from there to a PE conductor of the supply line. Preferably, the PE contact is designed as a scratch contact, which ensures contact with the mounting body when the first contact side is inserted into the busbar.

[0010] In one embodiment, the control gear forms the first contact surface on one side and the second contact surface on another. In this embodiment, the control gear itself thus forms the contact element. This embodiment can be particularly advantageous because it allows for a particularly space-saving and simple connection between the supply line and the busbar of the mounting body by means of the control gear. Furthermore, this simultaneously connects the control gear to the supply line and ensures that lamps connected to the busbar wires are supplied by the control gear. It is particularly preferred that the control gear is designed to be slidable along the busbar while maintaining electrical contact with the busbar wires.In another embodiment, the operating device is designed in such a way that it can be plugged onto the conductor rail at various points with respect to the longitudinal direction, but cannot be moved from one position to another while maintaining electrical contact with the conductor wires.

[0011] In general, the contact device is preferably fixed to the mounting rail in a specific longitudinal position, such that the longitudinal position of the contact device determines the longitudinal position of the contact assembly in its operating position. This is because, of course, the contact assembly must be connected to the contact device, and preferably, the contact assembly and the contact assembly are designed in such a way that the position of the contact device also determines its position in its operating position. In this way, the contact device and contact assembly can be implemented in a particularly cost-effective and simple manner.For example, the longitudinal position can be determined such that it is fixed to a longitudinal extent range that is less than 10%, in particular less than 5%, and in particular less than 2% of the longitudinal extent of the mounting rail. By defining the longitudinal position very precisely, the mounting rail and contact device can be manufactured particularly cost-effectively. It is especially preferred that the contact device on the mounting rail is fixed with its longitudinal position such that its longitudinal position and the longitudinal position of the contact device cannot be varied at all in the operating position.

[0012] In one embodiment, the first contact side is displaceable over at least 50% of the conductor rail while remaining connected to it. For example, the contact device can first be mechanically connected to the conductor rail via its first contact side, after which the contact device can then be displaced along its longitudinal direction relative to the conductor rail. This can particularly simplify the assembly of the mounting rail and the mounting body, as well as the electrical connection of the supply line and the light source or other functional elements. It is especially preferred that the first contact side be displaceable over at least 50% of the conductor rail's length while remaining mechanically and electrically connected to it.This can further simplify the realization of a luminaire according to the invention using a system according to the invention.

[0013] Preferably, the support rail has a U-shaped cross-section perpendicular to the longitudinal direction. The support rail has a bottom section opposite an open end in the vertical direction, from which two side walls extend vertically, spaced apart from each other in the transverse direction. This U-shaped design of the support rail allows for particularly cost-effective production and, moreover, enables easy connection to the mounting body, thereby defining the interior space. The mounting body is particularly preferably designed to be attached to the open end of the support rail in the operating position such that its upper surface faces the bottom section of the support rail, with the supply lines arranged within the U-shaped cross-section of the support rail.In this way, the mounting body can be attached to the support rail particularly easily, and furthermore, the contact device and contact assembly can be arranged in the interior and electrically connected to each other in a particularly simple manner. The support rail is preferably made of a sheet metal part, particularly by forming a sheet metal part. The mounting body is also preferably made of a sheet metal part, particularly by forming a sheet metal part.

[0014] In one embodiment, the conductor rail has a fixing device and the mounting body has a fixing device corresponding to the fixing device, wherein the conductor rail is held in the operating position on the mounting body by the interaction of the fixing device and the fixing device. Preferably, the conductor rail is held in a positionally fixed position on the mounting body such that movement of the conductor rail relative to the mounting body is only possible with a considerable force, in particular more than 10 N, and in particular more than 50 N. Particularly preferably, only the fixing device and the fixing device ensure the aforementioned holding of the conductor rail on the mounting body, independent of the interaction of the contact device and the contact device in the operating position. Particularly preferably, the conductor rail is held on the mounting body solely by the interaction of the fixing device and the fixing device.Particularly preferably, the conductor rail has a portion of the fixing device at each of its two transverse ends, wherein, in the operating position, a portion of the fixing device is arranged at each of the two transverse ends of the conductor rail, so that the conductor rail is held on the mounting body at its two transverse ends. Particularly preferably, the mounting body has a U-shaped cross-section perpendicular to the longitudinal direction with a mounting body base and mounting body walls, wherein the mounting body walls are spaced apart from each other in the transverse direction and extend vertically away from the mounting body base.Preferably, a section of the fixing device is provided on each of the facing sides of the mounting body walls, and a section of the fixing device is provided on each of the two transverse ends of the conductor rail. In the operating position, each section of the fixing device interacts with an associated section of the fixing device, thereby holding the conductor rail to the base of the mounting body. The mounting body is particularly preferably made of sheet metal, with the fixing device being provided by a formed sheet metal section. The conductor rail is particularly preferably manufactured by injection molding or extrusion. The conductor rail and the mounting body are particularly preferably designed to correspond to each other such that the fixing device presses the conductor rail against the base of the mounting body.

[0015] In one embodiment, the mounting rail comprises several contact devices. The system can also have a mounting rail arrangement with several mounting rails arranged longitudinally one behind the other, each of which has at least one contact device. The contact devices are particularly preferably identical. The system particularly preferably comprises several mounting bodies, each of which is suitable for being attached to the mounting rail of one of the mounting rails of the mounting rail arrangement in the operating position and, together with the mounting rail, surrounds an interior space of the luminaire around its longitudinal axis in the operating position. A light source or another functional element, for example, a sensor, camera, or radio module, is particularly preferably arranged on each of the mounting bodies and electrically connected to the supply lines in the operating position.Particularly preferably, some of the mounting bodies, instead of a conductor rail, each have a contacting device that can be fixedly connected to the mounting body in an associated longitudinal position and corresponds to the contact devices. This contacting device can only be made at the associated longitudinal position and, in the operating position, is electrically connected to one of the contact devices of the mounting rail or mounting rail assembly. The contacting device thus has one side that is designed analogously to the second contact side of the contact device of one of the mounting bodies, so that the contacting device can be joined with any of the multiple contact devices to establish an electrical connection. In the operating position, the contacting device of such a mounting body is fixedly connected to the mounting body at the associated longitudinal position.For example, such a contacting device can be designed as a plug that is fixed to the mounting body at a specific point and can be inserted into a contact device designed as a socket. The system according to this advantageous embodiment thus comprises several mounting bodies that can only be arranged in a position relative to the mounting rail or mounting rail assembly determined by the position of the contact device in the mounting rail, so that electrical contact can be made between the light source or other functional element of the mounting body and the supply lines of the mounting rail.This embodiment offers the particular advantage that some of the mounting bodies, which do not have a conductor rail, can be manufactured particularly cost-effectively, whereas at least one mounting body is provided which has a conductor rail, so that this mounting body ensures sufficient variability of the system, with several mounting bodies with conductor rails being particularly preferred.

[0016] The invention further relates to a luminaire manufactured using a system according to the invention. The luminaire according to the invention comprises a longitudinally elongated mounting rail and a longitudinally elongated mounting body, which is attached to the mounting rail and, together with the mounting rail, surrounds an interior space of the luminaire around its longitudinal direction. Supply lines are arranged on the mounting rail, and a light source or other functional element is arranged on the mounting body. The light source or functional element is electrically connected to the supply lines. A conductor rail with channels is provided on the mounting body, in which conductor wires are arranged and which are open on one side facing the interior space. The luminaire has a contact device with two contact sides and a contact device provided on the mounting rail, which is conductively connected to the supply lines.A first contact surface is inserted into the channels of the busbar and conductively connected to at least some of the conductor wires arranged in the channels. A second contact surface is designed corresponding to the contact device and is joined to it and conductively connected to it. The busbar preferably extends over at least 20%, in particular at least 30%, and in particular at least 70% of the longitudinal length of the mounting body. In the luminaire according to the invention, the elements of the system according to the invention are thus in the operating position. The luminaire particularly preferably comprises several mounting bodies that are attached longitudinally one behind the other to the mounting rail or to a mounting rail arrangement with several mounting rails arranged longitudinally one behind the other and, together with the mounting rail or mounting rail arrangement, surround an interior space of the luminaire around its longitudinal direction.Some of the mounting bodies, instead of a conductor rail, each have a contacting device that is fixedly connected to the respective mounting body in an associated longitudinal position and corresponds to the contact devices, wherein each contacting device is electrically connected to one of the contact devices of the mounting rail at its associated longitudinal position. The luminaire according to the invention may have further features that will be apparent to those skilled in the art from the explanations of various embodiments of the system according to the invention.

[0017] The invention further relates to a method for manufacturing a luminaire according to the invention. In a first step, the conductor rail is fixed to the mounting body. In a second step, preferably following the first, the mounting body and the support rail are mechanically connected to each other by means of a relative movement along the vertical direction. Particularly preferably, an electrical connection between the support rail and the mounting body is established during the mechanical connection of the mounting body and the support rail. This is preferably achieved by assembling the contact device provided on the mounting body and the contact device provided on the support rail during the mechanical connection of the support rail and the mounting body.The method according to the invention may have further features which are apparent to the person skilled in the art from the explanations of various embodiments of the system according to the invention and various embodiments of the lamp according to the invention.

[0018] The invention is explained in more detail below with reference to three figures and two exemplary embodiments.

[0019] They show: Fig. 1: in schematic principle representations a first relative arrangement of elements of a first embodiment of a system according to the invention; Fig. 2: in a schematic representation of principle, a second relative arrangement of elements of the system according to the invention Fig. 1; Fig. 3: in schematic principle representations an arrangement of the elements of a second embodiment of a system according to the invention.

[0020] In Fig. 1 comprehensive the Fig. 1a and Fig. Figure 1b shows schematic diagrams of elements of an embodiment of a system according to the invention. The system comprises a mounting rail 1 and a mounting body 2 on which a conductor rail 3 is arranged. The mounting rail 1 has a U-shaped cross-section with a base section and two side walls. The mounting body 2 has a U-shaped cross-section with a base and two walls. Supply lines and a contact device 42 are arranged on the mounting rail 1. A control gear 5 and a plug-in device 50 are arranged on the mounting body 2, by means of which the control gear 5 can be connected to the conductor wires arranged in the conductor rail 3. Fig. 1a shows the elements in an exploded view. Fig. Figure 1b shows the elements in their operating position. In the operating position, the conductor rail 3 is held securely to the base of the mounting body 2. For this purpose, the conductor rail 3 has a section of a fixing device 31 at each of its transverse ends, and the mounting body 2 has a section of a fixing device 21 on each of its mounting body walls. The fixing device 21 is realized here by forming the sheet metal from which the mounting body 2 is manufactured. In the operating position, the fixing device 21 presses vertically downwards against the fixing device 31, thereby reliably holding the conductor rail 3 to the mounting body 2. Fig. As can be seen in Figure 1b, in the operating position, the contact device 41 engages the channels of the conductor rail 3 with a first contact side and is electrically conductive against the conductor wires there. With a second contact side, the contact device 41 is inserted into the contact assembly 42, which is designed as a socket and is itself held on the mounting rail 1. In the present and generally preferred configuration, the contact device 42 is held in a positionally fixed position on the mounting rail 1 by the interaction of a holding device provided on the contact device 42 and a holding device provided on the mounting rail 1. Particularly preferably, the holding device and the holding device are provided at the transverse ends of the contact device 42, and the holding device is particularly preferably realized by forming the sheet metal from which the mounting rail 1 is made. Fig. Figure 1b also shows the feedthroughs in the contact device 42, in which continuous supply lines are arranged, with which the contact device 42 is in electrical connection. Fig. It is further evident from Figure 1b that the mounting body 2 closes the open end of the U-shaped cross-section of the support rail 1. The mounting body 2 is generally preferably held on the support rail 1 by mechanical locking mechanisms, in particular by a retaining spring provided on the base of the mounting body, which engages a retaining projection provided on the support rail 1. The provision of such retaining springs or, more generally, such locking mechanisms for fixing a mounting body 2 to a support rail 1 is well known to those skilled in the art.

[0021] In the embodiment according to Fig. 1. The operating device 5 is arranged longitudinally X behind the conductor rail 3 and is thus offset along the longitudinal direction X relative to the conductor rail 3. The contact device 41 can be inserted into the channels of the conductor rail 3 with its first contact side over the entire longitudinal length of the conductor rail 3, so that an electrical contact can be established between the contact device 41 and the conductor wires provided in the channels. The effect of providing the conductor rail 3 on the mounting body 2 is particularly evident from the combination of the Fig. 1 and Fig. Figure 2 shows the same embodiment of the system according to the invention, but with differently oriented elements. The support rail 1 according to the arrangement shown in Figure 2. Fig. 2 is in comparison to the mounting rail 1 according to the arrangement according to Fig. 1 offset along the longitudinal direction X to the mounting body 2. Both in the arrangement according to Fig. 1 as well as in the order according to Fig. 2 However, electrical contact between contact device 42 and conductor rail 3 is easily made possible by means of the contact device 41, since the contact device 41 only needs to be inserted into the conductor rail 3 at the desired location so that the contact device 42, which is fixed in position on the mounting rail 1, can be inserted into the second contact side of the contact device 41.

[0022] In Fig. 3 comprehensive the Fig. 3a and Fig. Figure 3b shows a further embodiment of a system according to the invention. This embodiment differs from the embodiment according to Fig. 1 essentially by the different design of the conductor rail 3, contact device 41 and contact assembly 42, as well as by the different arrangement of the control gear 5 and the conductor rail 3 relative to each other. In the embodiment according to Fig. In the embodiment 3, the operating device 5 is arranged along the transverse direction Y next to the conductor rail 3 and extends in the same longitudinal section as the conductor rail 3. This allows for an even longer design of the conductor rail 3 on the mounting body 2, which increases the variability of the mounting body 2 in the embodiment according to Fig.3 is further improved. Accordingly, the conductor rail 3 is designed such that it only has channels in a transverse section that is less than 50% of its transverse extent, and accordingly, the contact device 42 is designed so that it can be connected to the contact device 41 in this transverse section. Accordingly, a sufficiently large other transverse section is provided in which the control gear 5 can be accommodated. Further embodiments are conceivable, for example, arranging the control gear 5 in the vertical direction Z below the conductor rail 3, wherein the conductor rail 3 can then be pressed against the control gear 5 and the mounting body base, for example, by the interaction of the fixing device 31 and the fixing device 21. For example, the control gear 5 can be designed as a circuit board for this purpose.Other possibilities are also conceivable, for example arranging the operating device 5 vertically below the mounting body 2, so that the mounting body 5 can extend in the same longitudinal section as the conductor rail 3, but in any case is then arranged vertically next to the conductor rail 3.
