Description

The invention relates to a system with a lamp according to the preamble of claim 1.

Systems of the generic type comprise a lamp which is elongated in a longitudinal direction and which has a support rail which is elongated in the longitudinal direction and a mounting body which is elongated in the longitudinal direction. Typically, the mounting rail is used to fix the lamp to a structure, for example a ceiling. Electrical functional elements of the luminaire are usually attached to the assembly body, for example circuit boards with LEDs, radio modules, electrical lines and / or operating devices. When installing a lamp, the mounting rail is usually first attached to the structure and then the mounting body, which is equipped with the aforementioned electrical functional elements of the lamp, is fixed to the mounting rail, so that the mounting rail and mounting body form an interior space in which the essential elements of the lamp are arranged, for example circuit boards, operating devices, etc. Typically, the mounting rail and mounting body are each designed to be elongated in a longitudinal direction, preferably the longitudinal extent is at least 5 times the extent perpendicular to the longitudinal direction. The mounting rail usually has a cross-section perpendicular to the longitudinal direction, which is open along a vertical direction at a vertical end and is delimited along a transverse direction by two mounting rail side walls which are connected to one another by a mounting rail base running along the transverse direction and which extend vertically away from the mounting rail base. The mounting rail is usually attached to a component via its mounting rail base. The mounting body is usually arranged at the open vertical end of the mounting rail, so that the mounting body, together with the mounting rail, forms an interior space that is circumferentially enclosed by the mounting rail and mounting body perpendicular to the longitudinal direction. At least in some longitudinal sections, the enclosure of the interior, which is formed by the support rail and mounting body, can be interrupted in sections, for example to allow access to the interior, for example for air supply. The interior space is preferably enclosed uninterrupted and continuously over at least 80%, in particular at least 90% of its longitudinal extent, in particular over its longitudinal extent. The mounting body often has a cross section perpendicular to the longitudinal direction, which comprises a mounting body base extending in the transverse direction and mounting body side walls extending vertically away from the mounting body base on the two transverse sides of the mounting body base. In an operating position, the mounting body base is preferably arranged at the open end of the support rail. The mounting rail and mounting body are generally usually produced separately from one another. Particularly preferably, the mounting rail and / or mounting body are each made from a sheet metal by forming. Usually the assembly body is in one Operating state of the luminaire in which the luminaire is used as intended, held on the mounting rail by a retaining spring. A wide variety of possibilities for realizing such a retaining spring are known in the prior art. The retaining spring is usually firmly connected to the assembly body and has retaining projections which can be elastically deflected in the transverse direction. When mounting the mounting body on the mounting rail, the mounting body is usually moved along the vertical towards the mounting rail, ie towards its open end, until the mounting body rests on the mounting rail, during which movement the retaining projections of the retaining spring are deflected towards the transverse center of the mounting body in order to be able to be guided past the mounting rail holding anchors provided on the inside of the mounting rail side walls, whereby they are guided elastically transversely to the outside after passing the mounting rail holding anchors and form a form fit with the mounting rail holding anchors, in particular they snap into place behind these mounting rail holding anchors, so that the retaining spring on the assembly body the open side of the mounting rail facing away from the mounting rail base is fixed to the mounting rail, so that the mounting body, the mounting rail base and the mounting rail side walls enclose the interior of the luminaire. The mounting rail holding anchors are preferably designed as projections.

Frequently, a luminaire of a generic system also has a conductor rail, which is mostly made of plastic, in particular by means of an extrusion process, and which is also elongated in the longitudinal direction. The conductor rail is then usually arranged on an inner side of the support rail facing the interior space and is fixed on the support rail, in particular on the Support rail base and / or on at least one of the support rail side walls. The conductor rail extends over a substantial proportion of the length of the support rail, in particular over at least 80% of the longitudinal extent of the support rail. Usually, the conductor rail has a plurality of channels which are arranged next to one another along a line-up direction and which are open to an access side that is accessible from the interior. The line-up direction runs perpendicular to the longitudinal direction, in particular along the abovementioned transverse direction when the conductor rail is arranged on the support rail base, and the channels extend over the entire length of the conductor rail. At least one conductor wire is arranged in the luminaire, in particular in at least some of the channels of the conductor rail. The lead wires are usually connected to an external voltage source, in particular at at least one longitudinal end of the conductor rail, via which electrical energy and in particular electrical signals can be applied to the lead wires. For this purpose, an electrical connection device, which is arranged in particular at the longitudinal end, is usually connected in an electrically conductive manner to the lead wires. In most cases, one of the connection devices is provided at each end of the extension of the conductor wires, in particular at each longitudinal end of the conductor rail. The connection devices can be designed, for example, as mutually corresponding connection devices, for example a first as a plug and a second as a socket. With the provision of one connection device at each extension end of the conductor wires, in particular at each longitudinal end of the conductor rail, the conductor rail can have corresponding one at each of its two longitudinal ends Connection devices be connected so that the lead wires can form a through wiring.

Systems of the generic type are used in a wide range of applications, for example in warehouses, production halls, supermarkets or open-plan offices, with lights with a plurality of support rails and mounting bodies being used. The basic principle of the lights of generic systems is that the mounting rails form the electrical and mechanical infrastructure of these lights, whereas the mounting bodies are attached to the mounting rails and have the electrical functional elements that are required in the respective area of application. Of course, at least some of the electrical functional elements are usually designed as light modules with light sources, in particular comprising LED boards, for example, alternatively or additionally, further electrical functional elements can also be provided on the respective assembly body, such as a presence sensor (for example infrared sensor), a camera, a radio module , etc. The electrical functional elements are usually fixed to the assembly body.

The luminaire usually has a contact device via which an electrical contact is established between the lead wires and the at least one electrical functional element. A large number of such contact devices are known in the prior art. Such contact devices can be designed, for example, as conventional insulation-piercing and / or clamping contact devices and / or as plug-in contact devices, via which an electrical tap on the lead wires is ensured is, via which an electrically conductive connection is established between the lead wires and the respective functional element. In some generic embodiments, a conductor rail with channels running in the longitudinal direction is arranged on an inner side of the support rail facing the interior, the conductor wires being arranged in the channels. In such embodiments, contact devices can be fixed to the mounting body and have electrical contacts which are introduced into the channels of the power conducting rail while the mounting body is moved along the vertical towards the mounting rail until it rests against the open end of the mounting rail. In this intended operating state, the contacts are in electrically conductive connection with at least some of the conductor wires, the contact device producing an electrically conductive connection between the contacts and the at least one electrical functional element, so that the electrical functional element is connected to the corresponding conductor wires of the power conductor rail via the contacts is. The electrical functional element is usually supplied with electrical energy via the electrical connection between the contact device and the functional element, and the electrical functional element can also be connected to external electrical components via other of the lead wires, for example to an emergency power supply and / or to a control unit via which the electrical Functional element can receive control signals. In this case, a control line is usually formed in the support rail, in particular in the conductor rail, by two of the line wires, via which the control signals can be transmitted to the at least one electrical functional element. Usually, luminaires of generic systems are control lines through which Control commands are transmitted in accordance with the DALI standard. This DALI standard enables data transmission of approx. 1 kbit / sec, which is in any case sufficient for transmitting relevant control commands to the respective electrical functional element.

In typical applications, generic systems are used in such a way that a plurality of luminaire components, each of which comprises a mounting rail designed as explained, a mounting body designed as explained and a power conducting rail designed as explained, are arranged one behind the other in the longitudinal direction for the realization of a lamp, the mounting rails of the respective Luminaire components are mechanically coupled to one another and the lead wires, in particular the conductor rails, of the luminaire components are electrically connected to one another. In this way, elongated luminaire structures can be created over a large area, as is required in a large number of applications. A luminaire of the respective system thus comprises a multiplicity of support rails, mounting bodies and, in particular, conductor rails, which are each connected to one another as explained. Such lights are to be connected per se to external power sources and, in particular, control devices, so that there is always an electrical connection between the line wires, in particular the at least one power guide rail of the light, with external electrical devices by means of corresponding electrical connections. Systems of the generic type are therefore basically also suitable for transporting electricity for other purposes, in particular for electronic data transmission. This is problematic, however, since the lights of such systems are usually designed to be space-optimized and thus only little space in the interior for additional components is provided. In addition, the provision of a large number of additional wiring in the mounting rail is expensive. The transmission of data with the aid of the DALI protocol is hardly possible for data volumes of several Mbit or even Gbit, which are now common, since the DALI protocol only allows data transmission of a maximum of a few kbit / sec, which is not sufficient for conventional data transmissions. Thus, when using generic systems, separate data communication interfaces must always be provided, for example WLAN modules, in order to be able to transmit data from electrical elements such as cameras, which in turn can then be transmitted via further WLAN connections or additional LAN connections provided in the respective area of application. Connections are further transmitted. Although this is technically possible in principle, it is associated with high installation and maintenance costs.

The present invention is based on the object of providing a system which at least partially eliminates at least one disadvantage of known systems.

As a solution to at least one of the objects described, the invention proposes a system having the features of claim 1. The system according to the invention comprises a luminaire which comprises a support rail which is elongated in the longitudinal direction and a mounting body which is elongated in the longitudinal direction. The support rail preferably has a cross-section in the manner of a U-shape, which is formed by a support rail base running in a transverse direction and two support rail side walls running away from the support rail base in a vertical direction, the transverse direction and vertical direction each being perpendicular to the longitudinal direction and perpendicular to one another stand.

In an operating state of the luminaire that the luminaire has when it is used as intended, the assembly body is arranged on a vertical side of the carrier rail side walls facing away from the carrier rail base, ie on the open side of the carrier rail, forming an interior space enclosed by the assembly body, carrier rail base and carrier rail side walls. Conductor wires which are designed to supply the electrical functional element with electrical energy run in the interior. The system particularly preferably has a feed device which is designed to be connected to the line wires and is designed to apply a supply voltage to at least some of the line wires. The lead wires are particularly preferably designed to transmit an electrical power of over 100 W, in particular over 500 W, in particular over 1 kW, from the feed device to the electrical functional elements of the light in the operating state. It is particularly preferred in the operating state of the system the feed device is connected to an external electrical energy supply source, the at least one electrical functional element being supplied with electrical energy in particular exclusively via the lead wires, in particular via two of the lead wires, one of which is designed as a neutral conductor and the other as a phase.

All electrical functional elements are preferably supplied exclusively via the lead wires. At least one of the lead wires is particularly preferably designed as a PE conductor, which is in electrically conductive connection with the assembly body via a contact device.

In a preferred embodiment, on an inside of the support rail facing the interior space, in particular on the support rail base, a current conducting rail is arranged, which has channels running in the longitudinal direction. The channels are preferably arranged next to one another in the lined-up direction and run parallel next to one another along the longitudinal direction, the lined-up direction preferably running along the transverse direction. The channels are preferably designed to be open towards the interior, so that they can be contacted directly from the interior by a contact of a contact device that corresponds is designed to the channels, ie has such a cross section that it can be introduced into the channels on the open side of the channels. The channels are preferably open on their vertical side facing away from the mounting rail base, the current conducting rail being arranged and fastened to the mounting rail base. One of the lead wires is arranged in at least some of the channels, the luminaire having a contact device via which the at least one electrical functional element is connected to the lead wires in the operating state. In particular, at least one further conductor wire is arranged next to the conductor rail. Two of the line wires are particularly preferably designed as control lines which, in the operating state, are connected to a DALI interface of the at least one electrical functional element. These two line wires are thus designed to transmit DALI commands from a control device, which is connected to these line wires, to the electrical functional element. The system particularly preferably comprises such a DALI control device which is connected to two of the line wires which are connected to a DALI interface of the electrical functional element or the electrical functional elements. In the operating state, DALI commands are particularly preferably transmitted from these two conductor wires to the electrical functional element or the electrical functional elements. Particularly preferably, the lead wires comprise a first group of lead wires, via which the at least one electrical functional element is supplied with electrical energy, and a second group of lead wires that are designed to receive DALI commands from a control device that is connected to these lead wires, to be transmitted to the electrical functional element, preferably each group includes exactly two of the lead wires.

In one embodiment, the data line is in the operating state, in particular exclusively, on the data interface and on communication interfaces of the system, in particular the

Luminaire connected to enable data exchange between the data interface and the communication interfaces. The communication interfaces can be formed at least partially, in particular completely, by communication interfaces of the at least one electrical functional element that is or are supplied by the conductor wires. In some embodiments, the communication interfaces can also include communication interfaces of further electrical functional elements that consume little energy, in particular have a power consumption of less than 20 W, in particular less than 15 watts, such as a motion sensor or a camera, these further electrical functional elements being preferred can be supplied via their communication interfaces.

In an advantageous embodiment, the system comprises a data converter which is designed in particular to convert Ethernet data signals into a HomePlug standard (for example IEEE-1901-FFT, IEEE-1901-Wavelet or ITU G.hn). In the operating state, the data converter is preferably connected to the data interface, preferably in an electrically conductive manner. For this purpose, the data converter preferably has a plurality of contacts that are galvanically isolated from one another, preferably in a contact area, which are preferably connected in an electrically conductive manner to corresponding contacts of the data interface in the operating state. The data converter has a network interface for connection to a network line. The network interface is preferably a, in particular standardized, plug connection side, for example an RJ45 socket, into which a preferably complementary, in particular standardized, plug connection side the network cable, for example an RJ45 plug, can be plugged in. In the operating state, the network interface is preferably connected to the network line, in particular in an electrically conductive manner. In particular, in the operating state the data converter is designed to be connected via its network interface to a network line, in particular designed as an Ethernet line, while ensuring bidirectional data exchange between the network line and the data line. The data converter is designed in particular to receive and / or send data via the data interface and the network interface in the operating state, the data converter preferably simultaneously converting a data signal received via the data interface, which is modulated in accordance with the HomePlug standard, into a Data signal output via the network interface, which is modulated in particular in accordance with an Ethernet standard, and / or a conversion of a data signal received via the network interface, in particular modulated in accordance with the Ethernet standard, into a data signal output via the data interface, in particular in accordance with a HomePlug -Standard is modulated, is enabled. In particular, the data line and the network line differ in terms of their network topology. The data converter is preferably connected to at least one of the line wires, in particular in the operating state, in particular next to the data conductors. In particular, the data converter is arranged on the mounting rail, in particular in the interior of the lamp.

In a preferred embodiment, the data converter is designed, in particular in the operating state, via the data interface to transmit data signals to the data line according to FIG to a PLC standard, in particular according to one of the common PLC standards IEEE-1901-FFT or ITU G.hn or a standard with the same or higher transmission rate. In particular, the data signals can be received by at least one electrical functional element in the operating state. Preferably, no energy consumers that have a power consumption of more than 15 W, in particular more than 20 W, are supplied with electrical energy via the data line. The inventors have recognized that interfering influences on the data line, which influence a transmission speed when transmitting data via the data line, can be avoided in this way.

The system has at least one contact connection, which is designed in particular as a contact device. In particular, at least one of the contact connections is designed as a communication interface. At least some of the communication interfaces can be designed as communication contact devices, which are designed to be connected to corresponding communication contact devices in order to enable data exchange between the data interface and the corresponding communication contact device, the corresponding communication contact device on any terminal device, in particular one of the electrical functional elements or can be connected to a further, in particular external, data line. In general, at least one of the electrical functional elements can be one of the terminals, and accordingly at least one of the terminals can be an electrical functional element, each of the terminals preferably being one of the electrical functional elements. In particular, in the operating state at least one of the contact connections is connected to one of the terminal devices, in particular via a corresponding contact connection, and to at least one of the line wires in order to supply the terminal device with electrical energy. In one embodiment, the data line comprises in particular several of the data conductors that branch off from the first, second and / or third data conductors as electrical stub lines to the communication interfaces of the terminals, and that are preferably connected to the data interface, in particular forming a network. In particular, the network has a bus topology, in particular a fieldbus topology. The data interface can in particular be a standardized data interface. It is essential that data transmission protocols can be impressed on the data line via the data interface, via which a corresponding data rate can be transmitted to the data line. Corresponding data interfaces are familiar to the person skilled in the art, for example interfaces according to the HomePlug standard according to the IEEE-1901-FFT, IEEE-1901-Wavelet or ITU G.hn. It is also possible, for example, to implement the interface in accordance with, for example, the IEEE standard 802.3af-2013, -2003 or, for example, 802.3at-2009. In general, such a data interface is preferably designed so that data signals with different carrier frequencies can be transmitted via the data interface so that a correspondingly high data transmission rate can be guaranteed. Depending on the interface, for example, data with carrier frequencies in a frequency range greater than 1 kHz are used for this purpose, in particular in a range from 1 kHz to 200 kHz or from 1 MHz to 100 MHz. It is essential for the present invention that the The data interface of the system is connected to a data line, which is preferably arranged in the interior of the luminaire, so that data can be communicated at a correspondingly high transmission rate via the data line provided in the interior of the support rail. This represents a significant advance in comparison to conventional systems, since according to the present invention the infrastructure formed by the mounting rails can be used at the same time to implement data transmission at a high data rate.

In one embodiment, the first data conductor is formed by a first electrical conductor provided in addition to the lead wires, which is preferably fixed in the interior on the support rail and thus on an inside of the support rail. In this embodiment, the first data conductor is therefore provided in addition to the lead wires explained above, which are used for the electrical supply of the electrical functional elements and in particular for PE contact and in particular for the transmission of DALI control signals in the operating state. In this embodiment, the second data conductor is formed by one of the lead wires or a second electrical conductor provided in addition to the lead wires. The second data conductor can particularly preferably be one of the line wires which are connected to the DALI interface of the electrical functional element and via which DALI control commands are thus preferably transmitted in the operating state. By using one of the DALI line wires for the data line, the wiring complexity and the manufacturing costs of the system can be reduced. With the provision of a second electrical conductor provided in addition to the lead wires, the Manufacturing costs, however, interference between the transmission of DALI control commands and the transmission of data at a data rate of over 10 Mbit / s via the data line can be avoided particularly effectively. In an embodiment which is particularly advantageous in terms of production technology, the first and second, i.e. in particular both, data conductors of the data line are each formed by one of the line wires, with these two line wires being particularly preferred in this embodiment, which are connected to a DALI interface and are used for the transmission of DALI Control commands act, at the same time act as the data conductor of the data line, via which the data are transmitted at the specified data rate as intended. The inventors have recognized that this means that the system can be made particularly simple and inexpensive, whereas negative interferences still occur due to the considerable differences in the transmission of DALI control commands compared to the transmission of data at the corresponding data rate according to a common possible data transmission protocol can be kept low.

In one embodiment, the system comprises a data feeder which is connected to the data interface of the data line and which is designed in particular to feed data into the data interface with a voltage of at most 50V. In some embodiments, the data feeder is preferably formed by the data converter, it being possible for the data converter to have features of the data feeder. In one embodiment, the data feeder is designed as a PoE injector (Power-over-Ethernet injector). Such a PoE injector is usually used to output a data signal that is simultaneously used by a system included electrical devices can be supplied with electrical energy. The present advantageous embodiment, however, takes a different approach. According to this embodiment, a corresponding data feeder is provided on a lead wire provided separately from the supply line, ie the lead wires provided for supplying the electrical functional elements with electrical energy, this reliably preventing voltage fluctuations in the supply lines from leading to disruptions in data transmission. In one embodiment, the PoE feeder is only used to supply additional electrical functional elements that have a power consumption of less than 20 W, in particular less than 15 W, the remaining electrical functional elements, in particular all functional elements designed as lighting means, through the lead wires provided for supply are supplied. In the system according to the invention, the data feeder is particularly preferably designed exclusively for feeding data into the data line, so that no electrical energy is fed into the supply line via the data feeder that is consumed by an electrical functional element to supply its components.

In one embodiment, the data conductors of the data lines are arranged in the mounting rail in such a way that they run in the longitudinal direction and run parallel to one another. The data conductors particularly preferably run next to one another perpendicular to the longitudinal direction, so that the cross section of the first data conductor is arranged next to the cross section of the second data conductor, the data conductors each running in the longitudinal direction and parallel to one another, in particular over more than 80%, in particular more than 90%. the longitudinal extent of the mounting rail away. The inventors have recognized that for the standardized production of generic systems or luminaires of generic systems, the arrangement of the conductors parallel to one another is particularly advantageous and enables a particularly favorable manufacturing method. At the same time, the inventors recognized that in order to implement the high level of data transmission using these data conductors in accordance with common transmission standards, it is not absolutely necessary that the data conductors have to be twisted, for example, or must be laid in the form of a coaxial cable, but rather that two such data conductors have to provide data via conventional transmission standards can be transmitted at the correspondingly high data rate and over a sufficiently long length, in particular over a length of over 100 m, in particular over 200 m. In particularly preferred embodiments, the data line of the system has a length of over 50 m, in particular over 100 m m on. An essential finding of the inventors is that for the implementation of a corresponding data line in the system according to the invention it is already advantageous if this data line has a high data transmission rate of over 10 Mbit / s, in particular over 100 Mbit / s, in particular over 200 Mbit / s , whereas data transmission rates of several Gbit / s do not necessarily have to be implemented, which is essential for the implementation of a simple topology of the data line, in particular a fieldbus topology in which the data line comprises conductors that lead away as stub lines from the lines running parallel to one another to the electrical functional elements, in particular terminals, is particularly advantageous in simple embodiments. This is because it is already advantageous if, in corresponding systems, at least selected electrical functional elements have data with a correspondingly high level Transmission rate can be transmitted to the data interface of the system, for example by high-resolution cameras, but this does not necessarily require an extremely high data transmission rate.

The data conductors preferably extend over at least 60%, in particular at least 80%, in particular at least 90% of the longitudinal extent of the interior space, in particular predominantly in the longitudinal direction. In particular, the system has at least one electrical connection device. In particular, the electrical connection device can be connected to a corresponding electrical connection device. The electrical connection device can in particular be made in one piece. The electrical connection device is preferably designed in several parts, in particular a first component of the connection device is designed to connect at least two of the data conductors to one another in an electrically conductive manner, in particular along the longitudinal direction, and a second component of the connection device is designed to electrically connect at least two of the lead wires to one another to be conductively connected, in particular with the formation of a connection between two of the connection devices. The components can be designed separately from one another, so that in particular two of the first components or the second components can be connected to one another without the respective other components of the connection devices being connected to one another. In particular, two of the connection devices are electrically conductively connected to one another in the operating state. In advantageous embodiments, the connection device can also be designed in one piece and / or the first and second components can be connected to one another, in particular rigidly. This makes it possible at the same time, in particular with a movement to establish a connection between a plurality of the data conductors and a plurality of the lead wires. The electrical connection device can preferably be connected to the data conductors at one end of the data conductors, in particular furthermore connectable to further data conductors, while ensuring data signal transmission between the data conductors and the further data conductors. The further data conductors preferably run, in particular, at least in sections outside the support rail. The further data conductors can in particular be connected to one of the terminals which is arranged outside the support rail. In particular, the further data conductors are encompassed by the data line and are preferably designed essentially identically to the data conductors. In particular, at least one of the further data conductors is formed by one of the line wires.

The data conductors are particularly preferably arranged in the interior of the mounting rail in such a way that they can be contacted from the interior. The data conductors are particularly preferably arranged in such a way that they can be contacted by the contact device or a separate contact device, in particular a cutting contact device. The data conductors are thus preferably designed in such a way that free access to the data conductors is made possible in the interior space. This enables a particularly simple electrical connection of the data conductors to terminals that are arranged in the interior. It has been found to be particularly advantageous that direct current flows through the data conductors in order to transmit the data. In particular, the data converter, in particular the data feeder, is designed in such a way that it impresses the data on the data conductor by direct current flowing through the data conductor. In this way, interfering influences can preferably be minimized. Particularly The data converter, in particular the data feeder, is preferably designed in such a way that a voltage of at most 50 V is always impressed on the data conductors. This particularly reduces the risk of electricity-related accidents.

In an advantageous embodiment in which the data line has a fieldbus topology, the data conductors of the data line, which of course also includes the further data conductors, are arranged in particular in such a way that they are connected to one another at different junction points, in particular in the operating state. In particular, the junction points are arranged in a section in which the first and the second and in particular the third data conductor run in the longitudinal direction and parallel to one another. Thus, at least one data conductor has a junction along the longitudinal extension of the data line at various junction points of the data line. In particular, the system has several of the electrical connection devices, each of which is preferably designed to connect data conductor sections to one another in an electrically conductive manner, in particular the data conductor sections branching off from one another at the respective junction point, in particular in a cross or star shape. In particular, in the operating state at each of the junction points through the junction, one of the data conductor sections is led away from the data conductor section from which it is branched off, and in particular to a terminal. In particular, in the operating state, the data conductor sections are connected in an electrically conductive manner by the electrical connection devices at the junction points to form a network with a fieldbus topology. In particular, the data line has several Junction points, which are preferably arranged in the interior and spaced from one another along the longitudinal extent of the interior, in particular by at least 10%, in particular at least 20%, in particular at least 50%.

Particularly preferred is at least one, in particular at least some, particularly preferably all, electrical functional elements are connected to the lead wires for the exclusive supply of electrical energy through the lead wires. In particular, those, in particular all those, of the electrical functional elements for supplying electrical energy in the operating state are connected to the lead wires which have an electrical power of over 30 W, in particular over 60 W, in particular over 100 W, in particular over 500 W, for operation require. In particular, the lead wires are designed to transmit an electrical voltage, in particular at a normal operating voltage of over 100 V, from a preferably external electrical energy supply source to the terminals. In particular, the electrical functional elements can be connected to at least one of the conductor wires, which are designed as data conductors. The electrical functional elements, in particular all electrical functional elements, can preferably be supplied with electrical energy exclusively via those of the lead wires that are not data conductors. In particular, the electrical functional elements do not send and / or receive any data from or via the line wires via which they are supplied with electrical energy, as explained. At least one, in particular a majority, in particular all of the electrical functional elements are preferably designed as one of the terminal devices described in the present case.

According to one embodiment, at least one of the electrical functional elements is arranged outside the interior on the support rail, in particular on a side that is not illuminated by the light module. The light module preferably has an emission side from which it emits light in the operating state. The at least one of the electrical functional elements, which is arranged outside the interior space on the support rail, is thus preferably arranged on a side of the lighting module facing away from the emission side. The at least one of these electrical functional elements is preferably fastened directly to the support rail. In particular, the at least one of these electrical functional elements is essentially carried by the lamp, in particular by the mounting rail of the lamp.

In one embodiment, several terminals are connected to the data conductors, preferably directly, with their communication interfaces. There are therefore no network splitters such as switches between the data interface and the communication interfaces. The terminals can preferably be included in the system. At least some of the terminals, in particular all of the terminals, are particularly preferably designed as at least some of the electrical functional elements of the system. Particularly preferably, in the operating state, the terminals receive data via their communication interfaces and via the data conductors and / or the terminals in the operating state receive data via their communication interfaces and via the data conductors.

The inventors have generally recognized that the provision of a star topology in a mounting rail, as would initially be obvious for realizing data transmission with a high data transmission rate, for example using the Ethernet protocol, is associated with particular difficulties, since this entails a considerable amount of wiring Mounting rail would mean that a data line has to be laid from each data interface, for example a switch, to each terminal. This not only makes production more expensive, but also makes production difficult in principle, since only a very limited space is available in the mounting rail. With the provision of a fieldbus topology in which a terminal device is connected along the length of the data line at various junction points of the data line which are spaced apart from one another in the longitudinal direction and are provided on the same data line so that the data line runs through the junction points without interruption in the longitudinal direction is, the wiring effort and the space required for the data line in the mounting rail is minimized.

In particular, when three data conductors are provided, a higher data transmission rate, in particular 100 Mbit / s, is guaranteed than with two data conductors. The concept of a serial connection of the terminals to the Data line or to the data line of the data line can mean, for example, that the data lines are looped through the communication interfaces of the terminals or that junction points are provided on the data lines that are spaced from one another along the longitudinal direction and thus along the data line and from each of which electrical stub lines are provided branch off to the communication interfaces of the end devices.

A data feeder 8 is thus provided, via which data is fed into the data line 6, and the electrical functional elements 3, 300 are connected to branching points of the data line 6 via stub lines. In the Figure 5a The topology shown enables data to be transmitted via the data line 6 to or from the electrical functional elements 3, 300 with very simple cabling. In Figure 5b Instead, the typical star topology is shown, which is used in conventional networks operated in accordance with the Ethernet standard. In such a topology, a data feeder 8, for example a switch, is provided, a data line 6 having to be laid from this data feeder 8 to each electrical functional element 3, 300 in order to avoid data collisions. It is obvious that such a topology, which is usually used in Ethernet networks, is hardly suitable for use in mounting rails 1.
