Description

The invention relates to a system for realizing a lamp, a busbar for such a system and a lamp produced by means of such a system.

Generic systems are suitable for realizing a lamp that is elongated in a longitudinal direction and has a mounting rail that is elongated in the longitudinal direction and a current-conducting rail that is elongated in the longitudinal direction. The current conducting rail has channels running in the longitudinal direction, which are arranged next to one another in a transverse direction perpendicular to the longitudinal direction, so that they run in the longitudinal direction and next to one another. The transverse direction runs perpendicular to the longitudinal direction and connects two adjacent channels in the shortest possible way. The channels are preferably all arranged in a row next to one another along a straight transverse direction, preferably within a one-piece current-conducting rail. However, embodiments are also known, for example, in which the current-conducting rail has current-conducting rail sections in which the channels are each lined up next to one another along a straight line running perpendicular to the longitudinal direction, with the outermost channels of the current-conducting rail sections connected to one another by a perpendicular to the longitudinal straight line can be connected in the shortest way, which deviates from the aforementioned straight lines. Here, too, the transverse direction refers, as always, to a connection direction that runs continuously, starting from a channel located at one end of the conductor rail, to a channel located at the other end of the conductor rail and running perpendicularly through all channels and thus connecting two neighboring ones by the shortest route. At least one conductor wire is arranged in each case in at least some of the channels. The channels are designed to insulate the conductor wires running in them from one another. Correspondingly, the conducting wires also run elongated in the longitudinal direction. At least all ducts that are transversely spaced from an adjacent duct by less than 5 mm are usually formed by two duct walls connected by a duct bottom, whereby a receiving space is formed between the duct walls, in which a conductor wire is insulated from each adjacent conductor wire which is arranged in an adjacent channel. Conductor wire holders are formed in the channels for the insulated holding of conductor wires, wherein a conductor wire holder can be formed, for example, through the space between the channel walls together through both channel walls and in particular also the channel bottom or through a holder formed on each of the channel walls. The channels are preferably open on an access side, with the access side pointing perpendicularly to the longitudinal direction and in particular away from the channel bottom, for example perpendicularly to the transverse direction that connects the respective channel with at least one of its neighboring channels by the shortest path, so that the channels arranged in the channels Lead wires accessible from the access side and thus can be contacted, the channels preferably being continuously open on the access side over their longitudinal extension. The channels are preferably closed on their side facing away from the access side, with which the current-carrying rail is preferably mounted in contact with the mounting rail, in order to insulate the line wires from the mounting rail. The insulation of the conductors from one another is ensured, for example, by such an arrangement that two transversely adjacent conductors are either arranged at a sufficient distance from one another on different channel walls of a channel or are separated from one another by a channel wall running between them, which separates two channels from one another. Typically, the mounting rail is used to fix the lamp to a structure, such as a ceiling. The current conducting rail with the line wires arranged in its channels is used to supply power to electrical functional elements of the lamp, which are to be fixed at various longitudinal positions along the mounting rail to create a lamp and are electrically conductively connected to at least some of the line wires for the electrical supply. Generic systems often include corresponding functional elements, such as lighting modules, in particular including printed circuit boards with LEDs, control gear, radio modules, sensors such as cameras or other presence detection sensors, etc. Generic systems often also include at least one assembly body, in particular several identically designed assembly bodies. To realize a lamp by means of a generic system, at least one functional element and a contact device are usually mounted on the mounting body, and the mounting body is connected to the mounting rail and equipped accordingly to realize a lamp in the process, the contact device is brought into an electrically conductive connection with at least some, in particular all, of the line wires that are arranged in the current-conducting rail.

The mounting rail usually has a mounting rail base and two mounting rail side walls extending away from the mounting rail base in a vertical direction that is perpendicular to the longitudinal direction. The carrier rail base runs in a transverse direction between the carrier rail side walls, so that the carrier rail side walls are spaced apart from one another in the transverse direction by the carrier rail base. The transverse direction is perpendicular to the vertical direction and perpendicular to the longitudinal direction. The transverse direction along which the channels are arranged next to one another is preferably rectilinear and runs parallel to the transverse direction or corresponds to the transverse direction, as a result of which a particularly simple structure of the entire system can be implemented. The access side preferably points in the vertical direction. The support rail base and the support rail side walls together form a wall which delimits a receiving space which is open at both longitudinal ends of the support rail and is suitable for receiving the current conducting rail. The support rail often has a cross section perpendicular to the longitudinal direction, which is formed in the manner of a U-shape, so that the receiving space is not only open at the longitudinal ends of the support rail but also at a vertical end of the support rail. In the realization of a lamp by means of a generic system using the mounting body explained, the mounting body is usually mounted on the open vertical end of the mounting rail, so that the mounting body of the receiving space at its the Mounting rail base is vertically limited vertically opposite side. In order to realize a lamp, both the current conducting rail and the electrical functional elements are arranged in the receiving space. The mounting rail is usually fastened to a structure via its mounting rail base. The luminaire, which is realized by means of a generic system, usually has an interior space which is formed by the named receiving space of the mounting rail, the interior space being delimited by the mounting rail and mounting body with respect to the transverse direction and with regard to the vertical direction, and in the longitudinal direction is limited by mounting rail protective caps, which are arranged at the longitudinal ends of the mounting rail to realize the lamp, so that a protected interior space is formed for the functional elements. The support rail and the mounting body are generally usually produced separately from one another; the support rail and/or the mounting body are particularly preferably each produced from sheet metal by means of forming. The assembly body is preferably held by a retaining spring on the mounting rail to implement a lamp. For this purpose, the carrier rail usually has a side wall projection on the inner sides of its carrier rail side walls facing one another, the retaining spring being firmly connected to the mounting body and, in its state connected to the mounting body, having elastically deflectable retaining projections at its transverse end, which during a vertical mounting movement of the mounting body can be deflected towards one another elastically in the transversal direction with the retaining spring attached thereto, while they are being moved past the side wall projections of the support rail side walls, after which they are subject to elastically conditioned restoration and thus elastic conditional move away from each other in the transverse direction, whereby the mounting body can be reliably held on the mounting rail. The contact device is preferably fastened to the mounting body and electrically conductively connected to at least one electrical functional element, which is also fastened to the mounting body. The mounting body, contact device, current conducting rail and mounting rail are preferably designed to correspond to one another in such a way that during the assembly movement, contact fingers of the contact device are inserted into channels in the current conducting rail and the functional element is thus electrically connected to at least some of the conductor wires arranged in the current conducting rail via the contact device in an electrically conductive manner. For example, the side wall projections of the support rail side walls can be formed by reshaping the support rail side walls. In order to implement a lamp, it is first necessary for the system to be in an assembled state in which the current conducting rail is arranged in the receiving space formed by the mounting rail and is fastened to the mounting rail. Embodiments are known in which the current conducting rail is attached to at least one of the support rail side walls, wherein the current conducting rail can have in particular two current conducting rail sections, each of which is attached to a different one of the support rail side walls. The conductor rail is often fastened to the base of the mounting rail, which results in particular advantages in terms of simplifying the structure of the system and saving space. In any case, in the assembled state of the system, which describes a specific arrangement of components of the system relative to one another, the conductor rail extends longitudinally inside of the receiving space delimited by the wall of the mounting rail. A structure is thereby provided by the mounting rail and current-conducting rail, which allows the positioning of the functional element and the electrical supply of functional elements along the extension of the current-conducting rail and mounting rail. In the assembled state, the conductor rail usually extends over at least 80%, in particular at least 90%, in particular at least 95% of the longitudinal extension of the mounting rail. The current conducting rail is usually made of plastic, in particular by means of an extrusion or injection molding process.

A generic system is particularly preferably used to implement such an elongate lamp in which at least two lamp assemblies are arranged one behind the other in the longitudinal direction. Each of the lamp assemblies includes a mounting rail and a current-conducting rail, which are arranged relative to one another as explained with regard to the assembled state of the system. The two lamp assemblies are connected to one another by the mounting rails being mechanically connected to one another by means of a coupling and the conductor rails being connected to one another at their ends pointing towards one another by means of an electrical connector, which in each case has a conductor wire which is arranged in the conductor rail of one of the lamp assemblies, with a lead wire, which is arranged in the current conducting rail of the other lamp assembly, electrically conductively connects. In order to ensure the desired modularity of the system, the mounting rail and current-carrying rail of a generic system must be designed in such a way that they can form a lighting assembly that has a receiving space that can be closed at the longitudinal ends. and on the other hand can be connected to another lamp assembly as explained, in which case the two lamp assemblies each form a receiving space, the receiving spaces being connected to one another and jointly forming an overall receiving space which can be closed at its longitudinal ends so that a closed interior of a lamp can be realized can.

Generic systems are therefore specifically designed to be highly modular in order to enable the realization of a wide variety of lights. Luminaires realized by means of a generic system can thus comprise, for example, a large number of luminaire assemblies which are arranged one behind the other in the longitudinal direction and are connected to one another as explained. Furthermore, depending on the area of application and the resulting need, a wide variety of electrical functional elements and a wide variety of control options for the electrical functional elements can be provided in such a lamp. Since the mounting rail together with the current conducting rail provide the basic structure of each such light, which is realized by means of a generic system, the mounting rail and current conducting rail must be designed in such a way that, depending on the choice of the mounting body used, the contact device used and the functional elements used, they have a receptacle and enable supply of these components. This places high demands on the current-carrying rail in particular, since the current-carrying rail with the conductors arranged in it provides the electrical supply system of such a lamp and must therefore provide a sufficient number of different supply lines for electrical functional elements by means of the conductors arranged in it, in order to be able to use different functional elements depending on the application , the are arranged within the receiving space of the mounting rail or rails, to provide a different voltage supply and, if necessary, controllability and, if necessary, also to provide data lines via which data relating to the functional elements can be transmitted, be it data recorded by functional elements designed as sensors or data between Functional elements or data to functional elements that are used there for the targeted control of the respective functional element. In order to meet these complex requirements, current-carrying rails have now been developed with a very large number of conductor wires arranged next to one another in a transverse direction, which are still arranged in the current-carrying rail in such a way that they can be contacted from the access side of the current-carrying rail. Conductor rails with thirteen or more conductor wires arranged next to one another in the transverse direction are already known today. However, the guarantee of a high degree of modularity in the system, which is actually intended to save costs and efficiently design a wide variety of luminaires, has its limits. This is because the provision of a large number of line wires, which under certain circumstances are not used in certain applications, increases the manufacturing costs of lights which are only required for simple applications. Although this can be counteracted by the design of different conductor rails, which then have to be kept in stock in a wide variety of configurations and each have to be manufactured with individual tools. It must always be taken into account that the mounting rail and conductor rail must form a basic structure that must be able to correspond with a wide variety of functional elements and mounting bodies and contact devices and that should be easy to assemble in order to reduce the effort involved in Installation of lights to be kept to a minimum.

The object of the present invention is to provide a system, a conductor rail for such a system and a lamp with which at least one disadvantage of generic systems can be at least partially eliminated.

The invention proposes a system with the features according to claim 1 as a solution to the above-mentioned problem on which the invention is based.

bildbar ist, wobei über die an der jeweiligen Seite liegenden N Leitungsdrähte summiert wird und mi die Masse und di den Abstand des jeweiligen Leitungsdrahts i von der Mittenebene in einer Transversalrichtung beschreibt und die für die beiden Seiten gebildeten Summen sich um weniger als 20 %, insbesondere weniger als 10 %, insbesondere weniger als 5 % unterscheiden. Die Transversalrichtung verläuft senkrecht zur Mittenebene. Bevorzugt entspricht die Transversalrichtung der oben mit Bezug auf eine Ausführungsform erläuterten Transversalrichtung, in der der Tragschienenboden zwischen den Tragschienenseitenwänden verläuft. Die Erfinder haben dabei erkannt, dass die Anordnung der Leitungsdrähte wegen ihres Gewichts eine erhebliche Rolle bei der einfachen Montierbarkeit eines Systems zur Realisierung einer Leuchte haben. Denn die Leiter weisen aufgrund ihrer zwingend erforderlichen elektrischen Eigenschaft und des hierfür auszuwählenden Materials ein erhebliches Gewicht auf. Darüber hinaus sind bei entsprechenden Systemen häufig Stromleitschienen mit erheblichen Längserstreckungen vorgesehen, üblicherweise von bis zu 4 m oder gar bis zu 5 m, und entsprechend sind in solchen langen Stromleitschienen Leitungsdrähte mit einer Länge von über 4 m angeordnet. Ein solcher Leitungsdraht, der sich über 4 m erstreckt, weist ein erhebliches Gewicht auf, wobei das Gewicht von seinem Leiterquerschnitt abhängt. Üblicherweise weist ein 4 m langer Leitungsdraht ein Gewicht von ca. 70 g bis 150 g auf. Die Erfinder haben erkannt, dass die Anordnung eines Leitungsdrahts relativ zur Mittenebene für die Schwierigkeiten bei einer gleichmäßigen Ausrichtung von Tragschiene und Stromleitschiene im Betriebszustand des Systems und somit auch bei der Realisierung einer Leuchte von entscheidender Bedeutung ist, da eine ungeordnete Anordnung eines Leitungsdrahts außerhalb der Mittenebene zu einer unerwünschten Verkippung der Tragschiene bei Aufhängung der Tragschiene an einer Decke führen kann, was optisch weniger ansprechend ist und darüber hinaus die einzustellende Beleuchtung erschweren kann, da üblicherweise bei der Berechnung der Abstrahlcharakteristik einer Leuchte davon ausgegangen wird, dass die Tragschiene mit ihren Tragschienenseitenwänden entlang einer Vertikalrichtung verläuft, die parallel zur Gravitationskraftrichtung ist. Indem die Summe über das Produkt von Masse und Abstand eines jeden Leitungsdrahts an jeder Seite so eingestellt wird, dass die sich für die beiden Seiten ergebenden Summen kaum unterscheiden, kann ein Verkippmoment der Tragschiene effektiv reduziert sein. Dabei sei darauf hingewiesen, dass bevorzugt für jede Seite nur solche Leitungsdrähte zur Ermittlung der jeweiligen Summe herangezogen werden, die außerhalb der Mittenebene verlaufen, bevorzugt um mindestens 1 mm in Transversalrichtung von der Mittenebene beabstandet sind. Denn entlang der Mittenebene verlaufende Leitungsdrähte tragen üblicherweise keinen relevanten Beitrag zur Erzeugung eines Verkippmoments der Tragschiene bei Aufhängen der Tragschiene bei.The solution according to the invention is suitable for realizing a lamp, in particular a lamp which is elongated in the longitudinal direction and whose extent in the longitudinal direction is at least ten times, in particular at least twenty times, its extent in all directions perpendicular thereto. The system according to the invention comprises a support rail which is elongated in a longitudinal direction and a current-conducting rail which is elongated in the longitudinal direction. Support rail and conductor rail preferably each have a length in the longitudinal direction that is at least five times, in particular at least ten times, their lengths in every other direction perpendicular to the longitudinal direction. The support rail has a cross section perpendicular to the longitudinal direction, which, as explained in relation to generic embodiments, can be designed, for example, in the manner of a U shape. In any case, each longitudinal position of the support rail can be assigned a cross section running perpendicularly to the longitudinal direction, with the support rail preferably having a cross section with the same external dimensions over its longitudinal extension, ie extensions in any direction perpendicular to the longitudinal direction. The conductor rail shows preferably at least seven, in particular at least ten, in particular at least twelve, in particular at least thirteen channels which are elongated in the longitudinal direction and which are arranged next to one another in a transverse direction running perpendicular to the longitudinal direction, so that they are offset from one another perpendicular to the longitudinal direction, they are preferably like those of the generic type Systems explained, arranged lined up next to each other along a transverse direction perpendicular to the longitudinal direction. At least one conductor wire is arranged in each case in at least some of the channels. The conductor wires are not part of the current-conducting rail, but are arranged as intended in the channels of the current-conducting rail, at least in the operating state explained below. The channels preferably form at least ten, in particular at least twelve, in particular at least thirteen, preferably at least fifteen conductor wire holders, in which the conductor wires can be arranged at a distance from one another. Exactly one conductor wire holder is preferably formed by exactly one channel in each case, so that exactly one conductor wire is arranged in each channel and is electrically insulated from its adjacent conductor wire by a channel wall delimiting the channel. In one embodiment, two planes run through at least some of the channels, which are perpendicular to the longitudinal direction and are spaced apart, preferably by at least 2 mm, in particular by at least 3 mm, in particular by at least 4 mm, in each of these channels, through which these run both levels, one of the conducting wires is arranged in a first of the levels and another of the conducting wires is arranged in a second of the levels. The planes are preferably spaced apart from one another in a direction perpendicular to the transverse direction. These channels preferably each have one at the level of each of the planes Line wire holder, the line wire holders along the course of the planes are spaced from each other and thus the wires are correspondingly spaced from each other in the operating state. The arrangement in two levels can enable a particularly compact design, and the spacing of the conductor wire holders or conductors along the course of the levels can enable good contacting. In an operating state of the system, the current-conducting rail is fastened to the mounting rail and a central plane runs perpendicularly to the cross-section of the mounting rail through the mounting rail and the current-conducting rail. The center plane is an imaginary plane that is perpendicular to the cross section of the support rail and in which the longitudinal direction therefore runs. The definition of the center plane is used to define a common center of gravity of the mounting rail and current conducting rail in the operating state. In one embodiment, the support rail is symmetrical about the center plane. In one embodiment, the current conducting rail is symmetrical to the center plane. The central plane is generally preferably positioned in relation to the transverse direction in such a way that when the mounting rail and conductor rail are suspended in the operating state along an axis which is attached to the mounting rail base on an outside of the mounting rail base facing away from the receiving space along the intersection line between the mounting rail base and the central plane, the mounting rail side walls run in the vertical direction when no external force acts on the support rail and conductor rail apart from the gravitational force acting on the earth, with the vertical direction running parallel to the direction of the gravitational force. In general, the center plane in the transverse direction is preferably less than 10%, in particular less than 5%, from the common center of gravity of the mounting rail and current-conducting rail spaced apart, the central plane preferably runs through the common focus of the support rail and current-conducting rail in the operating state. The definition of a center plane is relevant for the explanation of the present invention, since the center plane represents a reference plane to which the design of the components of the system or their arrangement relative to one another relates. Particularly preferably, the definition of the central plane explained also applies to an assembly state in which the current conducting rail is attached to the mounting rail in the same way as in the operating state, with the difference that no conductor wires are arranged in the channels of the current conducting rail in the assembled state, whereas in the operating state in at least some of the Channels each at least one wire is arranged. Because the definition of the center plane applies both to the assembled state and to the operating state, the system can be designed to be particularly easy to handle and assemble, since the balance of the system is then maintained both in the assembled state and in the operating state. According to a solution according to the invention, fewer conductor wires are arranged in the first channels of the current-conducting rail than in the second channels of the current-conducting rail. In each of the first channels, fewer conducting wires are thus arranged than in each of the second channels. In one embodiment, no conducting wires are arranged in the first channels, so that the number of conducting wires in the first channels is zero, and at least one conducting wire is arranged in each of the second channels, preferably either exactly one conducting wire or exactly two conducting wires, with particular preferably the same number of conductor wires, preferably either one or two, are arranged in each of the second channels. Generally preferably, the first channels and the second channels together form all the channels of Conductor rail, so that each of the channels of the conductor rail is either one of the first channels or one of the second channels. It is generally preferred that only a maximum of 80%, in particular a maximum of 70%, in particular a maximum of 60% of the channels one of the conductors is arranged, so that the remaining channels are free of conductors. While the conductor rail can store a specific maximum number of conductors next to each other and electrically insulated from one another due to the number of its channels and the conductor wire holders formed by its channels, this number of conductors preferably being at least ten, in particular at least twelve, in particular at least thirteen, in particular at least is fifteen, fewer conductors are arranged in the channels of the current conducting rail in the operating state than is permitted by the current conducting rail. This enables cost savings, since only a smaller number of conductors is arranged in the conductor rail and thus both the production of the operating state is simplified, since fewer conductors have to be arranged in the conductor rail and less material is required for realizing the conductors. It must be taken into account here that the conducting wires are usually made of a metal, in particular copper or a copper alloy, which entails considerable costs. While usually a reduction in the number of conductors in the conductor rail of a generic system is not readily possible, since this changes the weight ratios in the system, which in the case of a conventional suspension of the carrier rail in the operating state on a ceiling, for example, causes the carrier rail to tilt with the conductor rail arranged therein brings, the inventors have recognized that the reduction in the line wires is then easily made possible without increasing the assembly work if the arrangement of the line wires in the current conduction rail is particularly targeted. According to a solution according to the invention, the conductor wires are distributed around the center plane in such a way that a sum S according to FIG $S={\displaystyle {\sum }_{i=1}^N{m}_i}\ast {\mathrm{i.e}}_i$

can be formed, with summation over the N line wires lying on the respective side and mi describing the mass and di the distance of the respective line wire i from the center plane in a transverse direction and the sums formed for the two sides differ by less than 20%, in particular less than 10%, in particular less than 5%. The transverse direction is perpendicular to the center plane. The transverse direction preferably corresponds to the transverse direction explained above with reference to an embodiment, in which the carrier rail bottom runs between the carrier rail side walls. The inventors have recognized that the arrangement of the conducting wires, because of their weight, plays a significant role in the ease of assembly of a system for realizing a lamp. Because the conductors have a considerable weight due to their absolutely necessary electrical properties and the material to be selected for this purpose. In addition, current conduction rails with considerable longitudinal extensions are often provided in corresponding systems, usually of up to 4 m or even up to 5 m, and correspondingly conductor wires with a length of more than 4 m are arranged in such long current conduction rails. Such a conducting wire, which extends over 4 m, has a considerable weight, the weight depending on its conductor cross-section. A 4 m long conductor wire usually has a weight of approx. 70 g to 150 g. The inventors realized that the arrangement of a conductor wire relative to the center plane is of decisive importance for the difficulties in aligning the mounting rail and current-carrying rail in the operating state of the system and thus also when realizing a lamp, since a disorderly arrangement of a conductor wire outside of the center plane leads to undesirable tilting of the carrier rail when the mounting rail is suspended from a ceiling, which is visually less appealing and can also make it more difficult to set the lighting, since when calculating the radiation characteristics of a luminaire, it is usually assumed that the mounting rail runs with its mounting rail side walls in a vertical direction that is parallel to the direction of the gravitational force. A tilting moment of the support rail can be effectively reduced by adjusting the sum of the product of mass and distance of each conductor wire on each side in such a way that the sums resulting for the two sides hardly differ. In this context, it should be pointed out that preferably for each side only those conductor wires are used to determine the respective sum that run outside the central plane, preferably at a distance of at least 1 mm from the central plane in the transverse direction. This is because line wires running along the center plane usually make no relevant contribution to the generation of a tilting moment of the mounting rail when the mounting rail is hung up.

In one embodiment, a maximum of exactly one conductor wire is arranged in each of the channels. Particularly preferably, the line wires are accessible on an upper side through a continuous channel opening in the longitudinal direction, with the upper side preferably pointing in the explained vertical direction, so that it is a vertical upper side. Particularly preferably the upper side, on which the line wires are accessible through the access opening formed by the conductor rail, is at the same height for at least 80%, in particular at least 90% of all the line wires, preferably the upper side of at most one of the line wires differs in height which is the top of all other lead wires. The height defines a position perpendicular to the top, preferably along the vertical direction. Generally preferably, the line wires extend over at least 90% of the length of the mounting rail and are accessible over at least 90% of the length of the mounting rail on its upper side. Since the majority, in particular all of the line wires, are at the same height with their upper side, a contact device that reliably contacts all of the line wires can be constructed in a particularly simple manner.

In one embodiment, the conducting wires arranged on a first side of the midplane are arranged over a distribution along the transverse direction that is different than a distribution along the transverse direction over which the conducting wires arranged in a second side of the midplane opposite the first side are arranged . In this context, it must be taken into account that the central plane naturally has two sides which point in different directions along the transverse direction. The distribution of all conductive wires not intersected by the midplane can thus be comprehensively specified by the distribution of a first group of conductive wires located on a first side of the midplane and by the distribution of a second group of conductive wires located on a second Side of the midplane is arranged.

All of the conducting wires, the distribution of which is referred to here, are transversely spaced from the center plane. The distribution of the conducting wires along the transverse direction denotes the distances along the transverse direction to the center plane at which the conducting wires are arranged on each of the two sides of the center plane. The inventors have found that by adhering to the distribution constraint as explained above, which relates to the sum of the product of mass and distance formed over the conducting wires arranged across the center plane being essentially the same for both sides, in spite of this, the distribution of the lead wires along the transverse direction can be set to vary for both sides. For example, more conductive wires may be disposed on a first side than a second side, with the conductive wires disposed on the second side being spaced further transversely from the median plane than the conductive wires disposed on the first side. This means that special requirements, particularly with regard to the possibility of always using the same contact device for a wide variety of purposes and for the most diverse configurations of the conductor rail with different numbers of conductors, can be taken into account by specifically adjusting the distribution of the conductors on both sides. In one embodiment, on the other hand, the line wires are distributed exactly identically on both sides of the center plane along the transverse direction, so that the center plane represents a plane of symmetry for the arrangement of the line wires.

In one embodiment, the number of first channels is at least two, in particular at least three, especially at least five. In one embodiment, the number of second channels is at least five, in particular at least seven. In one embodiment, the number of second channels is greater than the number of first channels. The inventors have recognized that due to the inventive arrangement of the conductors in the conductor rail, conductor rails can also be used in which the possibility of arranging a large number of conductors isolated from one another is given, with a large number of conductors being arranged in the conductor rail , but on the other hand, to save costs, many of the channels have received little or no lead wire. This is particularly advantageous with regard to the fact that, in order to implement different lights, the system can have conductor rails which are of identical design, but with more conductor wires being accommodated in some of the conductor rails than in others of the conductor rails, with each of these different conductor rails being connected to the mounting rail in this way can be that the above-explained operating state relating to the respective current-conducting rail and the mounting rail is realized without an imbalance state is generated.

In one embodiment, the conductors are arranged such that for each side of the center plane, all conductors arranged on the respective side of the center plane and spaced apart from the center plane together have a mass of at least 300 g, in particular at least 400 g. The inventors have recognized that the advantageous division of the conductors according to the invention is particularly relevant for current conduction rails in which conductors are arranged with a particularly high jointly formed total mass, in which case a correspondingly high mass of conductors is advantageously arranged on each side of the central plane. In general, the system is preferably designed in such a way that the conductor wires together weigh at least as much as the conductor rail. It must be taken into account here that, because of their required electrically conductive properties, the line wires are usually made of a material that has a significantly higher density than the material from which the current conducting rail is made. The conductor wires are preferably made of a material whose density is at least 1.5 times, in particular at least 2 times, the density of the conductor rail. Accordingly, the arrangement of the conducting wires in the conductor rail is particularly relevant for the balance of the system in the operating state.

In one embodiment, one of the line wires is arranged on a first side of the center plane in three line wire holders that are arranged directly one after the other in a transverse direction running perpendicular to the longitudinal direction and are formed by a group of phase selection channels of the channels, with at least one other, in particular all other of the Channels located to that side of the midplane and spaced from the midplane are free of lead wires. The channels thus comprise a group of phase-selection channels, this group of phase-selection channels forming the three conductor-wire supports arranged directly in the transverse direction. At this point it should be noted that the channels of the current conducting rail form the conducting wire holders on the current conducting rail, with a longitudinally running conducting wire being able to be arranged in each of the conducting wire holders, as explained above, due to their arrangement in the conducting wire holders the conducting wires are insulated from one another, with, as explained above, in one embodiment at least one of the channels forming a conducting wire holder on each of its duct walls, in another embodiment each duct forming exactly one conducting wire holder which is defined by itself, i.e. its channel shape between the channel walls delimiting it in the transverse direction. By selectively forming phase selection channels, which form three wire holders arranged directly one after the other in the transverse direction, a current-carrying rail fitted with wire wires, each of which is arranged in one of these three wire holders, can be used particularly advantageously in conjunction with a contact device in which one Phase selection between three different line wires is possible. It should be noted that such phase selection contact devices are widespread. With such a contact device, the contact finger can be arranged in three different positions in relation to the transverse direction, with a specifically desired conductor wire, which is arranged in the current-conducting rail, being contacted when the contact device is plugged onto the current-conducting rail, depending on the selection of the corresponding position. Accordingly, such a phase selection can be used to assign an electrical functional element, which is connected via the contact device to conductor wires arranged in the conductor rail, to a specific group of functional elements that are all supplied via the same conductor wire, also known as the same phase, so that such groups can be controlled on electrical functional elements via the central switching of the supply of the selected wire. It is particularly advantageous, the phase selection range To limit contact device to a small extent in the transverse direction, so that on the one hand there is no faulty contact and on the other hand in the contact device enough space for reliable contacting of other wires for other purposes is possible. The inventors have found that by arranging conducting wires in conducting wire holders arranged immediately adjacent to one another in the transverse direction, these requirements for the arrangement of phase selection conducting wires can be satisfied, while by the deliberate provision of empty channels located between the center plane and the phase selection channels are located, a distribution balance can be realized, which allows the assembly of the conductor rail with a small number of conductors. Thus, in the described embodiment, no lead wires are placed in some of the channels spaced from the midplane and located transversely between the midplane and the phase selector channels. At least one channel, in particular at least two channels, in particular at least three channels, is particularly preferably empty in the transverse direction between the central plane and the phase selection channels, so that no conductor wire is arranged in them. In one embodiment, one of the phase selection channels is that of the channels located on one side of the midplane that is transversely spaced furthest from the midplane. The transverse direction preferably runs in a straight line at least across the phase selection channels, in particular in the transverse direction. By providing the phase selection channels at an end area, relative to the transverse direction, the contact device can also be designed in its end area in the transverse direction to implement a targeted adjustability of the transverse position of its contact finger with which the phase selection is carried out.

The inventors recognized that this creates a large distance between these phase selection line wires, which are arranged in the line wire holders formed by the phase selection channels, and the center plane, which means that there is a risk of torque loading when the mounting rail is on a straight line , which runs through the central plane, is fixed, but that this danger can be counteracted effectively by targeted distribution of the remaining conductors in the current-conducting rail, while preventing negative tilting effects when mounting the mounting rail and current-conducting rail with the conductors arranged therein.

In one embodiment, the system comprises a contact device which can be fastened to the conductor rail when the system is in operation and which has a housing with contact fingers fixed therein, which each form an electrical contact at one of their vertical ends. The contact fingers are designed to each engage in one of the channels when the contact device is fastened, with an electrically conductive connection of their respective electrical contact to the conductor wire arranged in the respective channel. One of the contact fingers is designed as a phase selection contact finger that can be displaced in the transverse direction before the contact device is attached. The phase selection contact finger can be fixed in at least three different transverse positions on the housing. Correspondingly, by selecting the transverse position of the phase selector contact finger before attaching the contact device to the current conduction rail, which of the conductors that are held in the conductor wire holders formed by the phase selection channels of the current conduction rail, can be selected by the Phase selection contact finger is to be contacted. Thus, the contact device is designed to correspond to the current conducting rail in such a way that its phase selection contact finger in each of the three contact positions after the contact device has been attached makes contact with a different one of the line wires that are arranged in the line wire holders formed by the phase selection channels. Contact device and current conducting rail are preferably designed to correspond to one another in such a way that in each of the three transverse positions of the contact finger, the contact finger engages in a different one of the phase selection channels. Since the system comprises such a contact device, which engages in at least some of the channels of the current conducting rail after the contact device has been attached to the current conducting rail and contacts the line wire(s) arranged therein, the system can have a particularly advantageous modular design. The contact device can be fastened to the current-conducting rail, for example, indirectly via the mounting rail. For this purpose, the contact device is preferably attached to a mounting body, which in turn is fixed to side wall projections of the mounting rail side walls via a retaining spring, with the mounting body, mounting rail, current conducting rail and contact device being designed to correspond to one another in such a way that the contact device is attached to the mounting rail by means of the mounting body is attached to the current conducting rail, with the realization of an electrical contact between the contact fingers and the conductor wires arranged in the current conducting rail.

In one embodiment, the system has a plurality of conductor rails, each of which has an identical number Channels, in particular at least seven, in particular ten, in particular at least twelve, in particular at least thirteen channels. The current conducting rails preferably each have an identical number of conductor wire holders formed by the channels. Particularly preferably, the conductor rails each have an identical cross section, at least over a longitudinal section. The current conducting rails are particularly preferably of identical design. In each case one of the conductor rails forms a conductor rail together with the line wires arranged in their channels. An arrangement consisting of line wires and current-conducting rail is thus referred to as a busbar. The conductor rail can be fastened to the mounting rail in order to implement the operating state. In this case, the current conducting rail of the busbar is fastened to the mounting rail in order to implement the operating state, with the conductor wires being held fixed in the channels of the current conducting rail of the busbar. More than five and fewer than eight line wires are particularly preferably arranged in the channels of a first busbar of the system. At least eight and fewer than twelve line wires are particularly preferably arranged in the channels of a second busbar. At least twelve and fewer than fifteen conductor wires are particularly preferably arranged in the channels of a third busbar. The system comprises at least two of first, second and third busbars, preferably the system comprises first, second and third busbars. By providing a system that has busbars with a different number of conductors, so that a different number of conductors is arranged in different conductor rails of the system, the conductor rail can be specifically selected depending on the desired functionality of a light, which has the number of wires required for functionality. This can prevent the production costs and the ecological burden from being excessively increased for the realization of simply structured lights. Due to the distribution of the conductors according to the invention, which preferably applies to each of the busbars, so that the conductors are arranged in each conductor rail of the respective busbars as explained for advantageous embodiments according to the invention, the mountability of the mounting rail and busbar in the operating state can always be simplified while preventing undesired tilting moments when mounting the mounting rail on a structure.

In one embodiment, the support rail has a fastening device, via which it can be fastened suspended from a ceiling by means of a fastening device corresponding to the fastening device by interlocking of fastening device and fastening device, as a result of which they rest on one another via a contact surface. Fastening device and fastening device are designed to correspond to one another. The support rail can be fastened by bringing the fastening device and fastening device into engagement with one another, so that they rest against one another across a bearing surface. The center plane runs through the fastening device, in particular through the contact surface. When the mounting rail is fastened to the ceiling by means of the fastening device, the mounting rail exerts a torque on an axis of rotation running in the longitudinal direction through the contact surface, depending on its mass distribution around the center plane. This torque is due to the targeted distribution of the conductors according to the invention kept as low as possible, this torque is preferably approximately zero, in particular exactly zero. The fastening device and the fastening device can be implemented in a known manner. For example, the fastening device can comprise a clamp which grips undercuts formed on the support rail side walls, the fastening device forming an eyelet which is cut through the central plane, the fastening device being designed as a cable suspension running through the eyelet. The fastening device can also be designed, for example, as an eyelet provided on the outside of the support rail base, into which a cable suspension or hook suspension can be inserted. A contact surface is always formed, the contact surface preferably running perpendicularly to the vertical direction and thus holding the weight of the mounting rail exerting a weight force along the vertical direction.

Generally preferably, the line wires each have a cross section perpendicular to the longitudinal direction of more than 2 mm ² , in particular at least 2.5 mm ² . This allows a signal, such as a data signal or a power supply signal, to be transmitted through a conducting wire with little loss. Although this means that the conducting wire has a considerable mass, an undesired tilting effect can nevertheless be effectively prevented by the targeted distribution of the conducting wires. A ratio between a width of the mounting rail in the transverse direction, specified in millimeters, and a number of line wires arranged in a specific current-conducting rail of the system in the operating state is generally preferably a maximum of six, in particular a maximum of five. Thus, an operating state of the system can be realized in which a very large number of conductor wires are arranged in the transverse direction next to each other within the support rail. As a result, a considerable mass of line wires is arranged in the mounting rail. However, the targeted distribution of the line wires can prevent a negative effect that can complicate the assembly of the mounting rail and current-carrying rail in the operating state. The system preferably has a plurality of groups of busbars, in particular a group of first busbars, a group of second busbars and a group of third busbars, as explained above, with the number of conductor wires arranged in the busbars being different, with only in a group of busbars, the ratio between the width of the support rail in the transverse direction and the number of conductors is a maximum of six, in particular a maximum of five, but in other groups of busbars it is greater than five, in particular greater than six, in particular greater than seven, in particular greater than eight is. The central plane generally preferably runs through one of the channels, preferably through the conductor wires arranged in this channel. This channel or wire is thus not located to one side of the midplane as defined above, since it is intersected by it. It is generally preferred that the lead wires are arranged symmetrically about the center plane such that the center plane forms a plane of symmetry with respect to the arrangement of the lead wires.

The busbar and the conducting wires of the busbar are a conducting bar and conducting wires of the system, so that a conducting bar and conducting wires of the system arranged in it are provided by the busbars. Fewer conductors are arranged in the first channels of the current-conducting rail than in the second channels of the current-conducting rail, with the conductors being distributed around the center plane in such a way that a sum S according to S = for both sides of the center plane ${\displaystyle {\sum }_{i=1}^N{m}_i}\ast {\mathrm{i.e}}_i$

The lamp comprises a mounting rail and a power rail of the system, with the power rail on the mounting rail is fixed and a center plane runs perpendicular to the cross section of the mounting rail through the mounting rail and the current conducting rail, with fewer conductors being arranged in the first channels of the current conducting rail than in the second channels of the current conducting rail, with the conductor wires being distributed around the center plane in such a way that for both sides of the midplane a sum S according to $S={\displaystyle {\sum }_{i=1}^N{m}_i}\ast {\mathrm{i.e}}_i$

In figure 1 a conductor rail 3 and a mounting rail 1 of an embodiment of a system according to the invention are shown in a schematic representation in a cross-sectional view, the cross section running perpendicular to the longitudinal direction X and thus running along the transverse direction Y and the vertical direction Z. The mounting rail 1 has a mounting rail base 13 and two mounting rail side walls 11 extending vertically away from the mounting rail base 13 . The support rail base 13 extends in the transverse direction Y between the support rail side walls 11 and connects them. The support rail side walls 11 each have a fixing projection 14 and a side wall projection 12 . The current conducting rail 2 of the current rail 3 shown is fixed on the fixing projection 14 . For this purpose, the current conducting rail 2 has lateral projections which are in the operating state in engagement with the fixing projections 14 and thereby the current conducting rail 2 in the vertical direction Z against the Press support rail bottom 13. The provision of such lateral projections on the conductor rail 2 or such fixing projections 14 is generally advantageous according to the invention. According to the invention, the current conducting rail 2 can generally advantageously be implemented in a fixed position on the mounting rail 1, realizing the operating state in which the current conducting rail 2 is moved in the vertical direction Z relative to the mounting rail 1, whereby it is guided with its lateral projections behind the fixing projections 14 as a result of this vertical movement under latched mounting of the current conduction rail 2 relative to the mounting rail 1. The system also has a contact clip 5, which is held pressed to the mounting rail 1 by this, although in figure 1 not shown, against the fixing projection 14 presses. The contact clip 5 provides a PE contact between one of the conductor wires 4, which is arranged in the current-conducting rail 2, and the mounting rail 1, so that the mounting rail 1 is grounded. The current conducting rail 2 has channels 20 which are arranged in a row in the transverse direction Y next to one another. The transverse direction Y is perpendicular to the vertical direction Z and to the longitudinal direction X and, in the embodiment described, corresponds to the transverse direction explained above, along which the channels 20 are lined up. The channels 20 are each open on a vertical side. This vertical side corresponds to the access side of the current-conducting rail 2. On this access side, the conductor wires 4, which are arranged in the channels 20 of the current-conducting rail 2, are accessible on their vertical upper side, so that they can be electrically conductively contacted in a simple manner by contact fingers of a contact device, not shown can. On their vertical side facing away from the access side is how According to the invention, it is generally advantageous if the conductor rail 2 is designed to be insulating, so that the channels 20 are not accessible from this side. Rather, the conductor rail 2, as is generally advantageous according to the invention, has insulating webs 22 on this vertical side, by means of which it is supported on the carrier rail base 13 of the carrier rail 1 in an electrically insulating manner. On the side wall projections 12 is an in figure 1 mounting body of the system, not shown, can be fixed in position by means of a retaining spring. In the present exemplary embodiment, a contact device is provided on the mounting body, the mounting body being connected thereto by a vertical movement relative to the mounting rail 1, as in FIG figure 1 shown in the operating state, fixed busbar 3 can be fixed to the mounting rail 1 by the retaining spring gripping behind the side wall projections 12, with this vertical relative movement of mounting rail 1 and mounting body the contact fingers of the contact device can be inserted into the channels 20 during the vertical movement under electrically conductive Contacting of the conductor wires 4 arranged therein when the holding body is held on the side wall projections 12 by means of the holding spring.

At the in figure 1 shown embodiment is in each of the channels 20 in each case a wire 4 is arranged. A corresponding conductor rail 3 is in figure 2 shown in more detail in a schematic diagram. Out of figure 2 it can be seen that the conductor wires 4 are held fixed in the channels 20 of the current conducting rail 2 of the current rail 3 . For this purpose, the duct walls of the ducts 20 have fixing devices 21 which protrude from the duct walls in the manner of a projection and thereby press against the conductor wires 4 in the vertical direction. while in figure 1 the Lead wires 1 are generally denoted by the reference numeral 4 is in figure 2 made a more detailed designation of the lead wires. The central conducting wire is designed as a PE conducting wire 44 . The center plane M runs through this PE conductor wire 44 and is only sketched in the present case by a line to characterize its position in the transverse direction Y. The bus bar 3 also includes a group of line wires which are in the form of phase selection line wires 41, 42, 43. These three phase selection line wires 41, 42, 43 are arranged in channels 20 of the current conducting rail 2, which are arranged directly one after the other in the transverse direction Y. In the present exemplary embodiment, the channels 20 directly form the conductor wire holders for the respective conductors due to their channel structure. The outermost phase selection lead wire 41 is the lead wire which is spaced farthest from the center plane M in the transverse direction Y on one side of the center plane M . The current conducting rail 4 also has a group of three further conductor wires which are arranged at the edge on the opposite side of the central plane M, this being a neutral conductor conductor wire 45 and data conductor conductor wires 46, 47 in the present case. In addition, further conductor wires 40 are arranged in a row in the transverse direction in the channels 20 . How out figure 2 As can be seen, the distribution of the conducting wires is completely symmetrical with respect to the median plane M.

In figure 3 a further conductor rail of the embodiment of the system according to the invention is shown. In this Stromleitschiene 2, the other wires 40 are no longer provided, so that only a smaller number of wires in the Conductor rail 2 of the busbar 3 is arranged. Nevertheless, the arrangement of the conducting wires 4 in the current-conducting rail 2 is also in accordance with FIG figure 3 perfectly symmetrical about the median plane M. In figure 4 a further conductor rail 3 of the embodiment of the system according to the invention is shown. This embodiment includes, in addition to the lead wires according to FIG figure 3 additional line wires 48, 49, which are presently designed as additional supply lines. In order to maintain the balance of the conductor rail 3, the conductors are distributed in a targeted manner around the center plane M such that for each side of the center plane M the sum of the product of mass x distance across the conductor wires arranged on the respective side is the same for both sides. Thus, in accordance with the embodiment figure 4 the balance of the busbar 3 is maintained. Generally preferred, the present invention relates to a lamp in which the line wires arranged directly next to one another in the phase selection channels are connected as phase conductors of the lamp and another line wire is connected as neutral conductor of the lamp and two other line wires are connected as data conductors, in particular as DALI conductors of the lamp and another line wire is connected as a PE conductor of the lamp, with the lamp preferably only having the line wires mentioned, but its current conducting rail having line wire holders for the insulated arrangement of at least 10, in particular at least 13 line wires next to one another perpendicular to the longitudinal direction.
