Description

AREA OF INVENTION

[0001] The invention relates to a lighting arrangement with a rail and a coupling unit for a lighting arrangement with a rail, in particular for lighting purposes in buildings, for example in the interiors thereof. TECHNICAL BACKGROUND

[0002] Lighting systems based on track lighting, for example for lighting purposes in buildings, are already known. Systems have been proposed, for instance, in which electrical conductors are integrated into a track profile to provide a supply voltage and control signals. Such track systems include, for example, a number of different types of light inserts, such as spotlights or linear light inserts, which can also be combined.

[0003] Furthermore, for example, EP 3 336 420 B1 describes a lighting system that includes a channel for accommodating a lighting unit that can be inserted into it. A connector that can be inserted into the channel is designed to electrically couple sections of the busbar. When inserted into the channel, the lighting unit and the connector can be arranged overlapping within the channel.

[0004] EP 3 495 726 A1 describes a lighting device with a connecting body that can be mechanically and electrically connected to a guide and that can be inserted into and removed from the guide at least in one direction perpendicular to its longitudinal extent.

[0005] Furthermore, for example in EP 3 217 090 B1, an adapter is described which is intended to carry a lighting device and connect it electrically to an electrified rail.

[0006] Furthermore, EP 3 719 394 A1 describes a lighting device comprising a luminaire and an adapter. The adapter serves to connect the luminaire to a rail as a support. A connecting section of the adapter has a sliding element that can be slidably connected to the rail serving as the support. The luminaire itself has a guide rail with primary electrical contacts, while the adapter has a carriage with secondary electrical contacts that is slidably connected to the guide rail. An intermediate section is provided between the carriage and the connecting section, defining a pivot joint between the carriage and the connecting section.

[0007] In addition, a rail system has already been proposed that can be suspended and mounted, providing an additional indirect lighting component.

[0008] However, in conventional cases, the installation of the components that provide the indirect light component is often only possible in an inflexible manner and / or with relatively great effort.

[0009] This is a situation that needs improvement. SUMMARY OF THE INVENTION

[0010] Against this background, the invention aims to provide a lighting arrangement that makes it possible to provide an indirect light component in a simpler manner. Furthermore, a coupling unit for forming a lighting arrangement is to be provided that makes it possible to easily couple it with another component of the lighting arrangement, such as a component for indirect lighting.

[0011] According to the invention, this problem is solved by a lighting arrangement with the features of claim 1.

[0012] A lighting arrangement is proposed, consisting of a rail, at least one indirect lighting module, and a coupling unit.

[0013] The rail is designed for coupling and / or at least partially accommodating at least one lighting module or at least one lighting unit and has an inner section in which a conductor is provided along the rail, at least for supplying electrical power to the lighting module or lighting unit. The indirect lighting module is designed to provide indirect lighting. The coupling unit is connectable to the rail and is configured to receive electrical power from the conductor and supply the indirect lighting module with electrical power. The rail has a web that forms a boundary for the inner section of the rail equipped with the conductor. The rail has a through-opening in the area of ​​the web.The coupling unit has a contact section that can be passed through the through-hole to bring about an electrical coupling of the indirect lighting module with the coupling unit.

[0014] Furthermore, a coupling unit for a lighting arrangement, in particular such a lighting arrangement according to the invention, is disclosed herein, which also solves the above problem. The coupling unit can be inserted into a rail of the lighting arrangement and coupled to the rail. The coupling unit has a first contact element for making electrically conductive contact with conductors of a conductor arrangement extending along the rail. The coupling unit also has a contact section designed to be inserted into a through-opening in a web of the rail when the coupling unit is inserted into the rail. A second contact element arranged on the contact section is provided for making electrically conductive contact with a contact element of another component and electrically coupling the coupling unit to the other component.The other component could be, in particular, an indirect lighting module.

[0015] One of the underlying concepts of the invention is that by providing a through-opening in a web of a rail and inserting a contact section of a coupling unit into the through-opening, a significantly simplified supply to the other component, which is in particular designed as an indirect lighting module, is achieved. A particularly advantageous simplification can be achieved if the other component is to be arranged on the other side of the web with respect to the coupling unit.

[0016] Supplying power to the other component, particularly the indirect lighting module, therefore does not require conventional, cumbersome wiring at a factory-predefined location, which would typically be done on-site. Instead, it can be significantly simplified by incorporating a through-hole – either as a pre-fabricated opening in the rail or by flexibly creating one on-site – and using this opening for electrical connection. In this way, the conductor system within the rail can be advantageously used to supply power to the other component, and establishing the connection requires only a few simple steps.

[0017] Advantageous embodiments and further developments of the invention will become apparent from the further dependent claims and from the description with reference to the figures.

[0018] In one embodiment, the coupling unit and the indirect lighting module are arranged for electrical coupling such that the indirect lighting module is displaceable along a longitudinal direction of the rail relative to the coupling unit coupled to the rail. This allows adjustments to the position of the indirect lighting module along the rail even after the coupling unit and the electrical coupling of the coupling unit and indirect lighting module have been installed.

[0019] In particular, the contact section is located on one side of the coupling unit that faces the web when the coupling unit is inserted into the rail. This facilitates easy insertion.

[0020] In a preferred embodiment, the contact section is designed as an extension of a body of the coupling unit. In particular, the contact section is rigidly arranged on the coupling unit. This can also contribute to simple and convenient handling of the coupling unit.

[0021] In some configurations, the cabling effort for supplying the other component, especially the indirect lighting module, can be significantly reduced, or cabling for this purpose can even be completely avoided.

[0022] In one embodiment, the coupling unit has contact elements, in particular point contact elements, whose interaction with associated elongated contact elements of the indirect lighting module enables, in particular, a sliding electrical coupling with the indirect lighting module. Specifically, the contact elements of the coupling unit are provided on its contact section. For example, in the case of an indirect lighting module with a relatively elongated shape, elongated contact elements can be provided relatively easily, resulting in a comparatively compact contact section. Such an embodiment can help avoid wiring complexity and allows for particularly simple and quick assembly.

[0023] In a further development, the elongated contact elements extend along the longitudinal direction of the rail when the indirect lighting module is coupled to the rail. This advantageously contributes to a simple and practical sliding coupling.

[0024] In particular, the elongated contact elements of the indirect lighting module are designed in a strip-like shape.

[0025] Preferably, the elongated contact elements of the indirect lighting module are arranged on one side of the module facing the coupling unit when the coupling unit is inserted into the rail and the indirect lighting module is coupled to the rail. This further simplifies the electrical coupling of the indirect lighting module and the coupling unit.

[0026] The contact elements of the coupling unit are designed in a pin-like or pin-head-like manner in a further development.

[0027] In one embodiment, the indirect lighting module has a double-sided printed circuit board, wherein the contact elements of the indirect lighting module are formed as conductive traces on a main surface of the printed circuit board. Such contact elements can be expediently manufactured.

[0028] In particular, the double-sided circuit board is equipped with light-generating devices, such as LEDs, on its other main surface. Specifically, the functions of light generation and contact establishment with the contact elements of the coupling unit can thus be combined on the double-sided circuit board, which can contribute to savings in space and assembly effort.

[0029] According to another embodiment, the coupling unit and the indirect lighting module are designed to achieve electrical coupling via cabling. Such a design can be implemented cost-effectively and, in particular due to the flexible positioning of the through-hole, can contribute to achieving coupling in a simple and straightforward manner, even when using cabling.

[0030] In advanced training courses, the opening in the rail, intended for connecting the coupling unit and the indirect lighting module, can be pre-cut at the factory or on-site during the installation of the lighting system. Specifically, the opening can be created at any point along the rail using methods easily accessible to a technician or skilled worker, such as drilling. This allows for a high degree of flexibility in the positioning of the coupling unit(s) and lighting modules.

[0031] In one embodiment, the conductor assembly is arranged in the inner area of ​​the rail such that conductors of the conductor assembly are located laterally to the coupling unit when the coupling unit is inserted into the inner area of ​​the rail. The conductors can run in the inner area, in particular along the longitudinal side walls of the rail, for example, on both sides of the coupling unit when it is inserted into the inner area. Such an arrangement of the conductors further simplifies the electrical contact between the coupling unit and the indirect lighting module and can be designed to be compact and space-saving.

[0032] In one embodiment, the conductor assembly is further configured to provide a control signal, wherein the coupling unit is configured to receive the control signal from the conductor assembly and to transmit a signal to the indirect lighting module for its control and / or to control the indirect lighting module. In particular, the coupling unit can be configured to forward the received control signal to the indirect lighting module, or to interpret the received control signal and, based on the received control signal, to control the indirect lighting module and / or to generate a signal to be transmitted to the indirect lighting module based on the received control signal.

[0033] The contact devices of the coupling unit and the indirect lighting module, which can be brought into operative contact with each other, can be designed in particular for forwarding the control signal or for transmitting the signal formed from the control signal.

[0034] In a preferred embodiment, the conductors of the conductor arrangement comprise first conductors for providing electrical energy to supply the lighting module or lighting unit, and one or more second conductors for providing a control signal, for example a DALI signal.

[0035] In one embodiment, it is provided that the control signal provided at the conductor assembly can be interpreted by the indirect lighting module contacted with the coupling unit via the contacting section or by the coupling unit itself.

[0036] In one embodiment, the rail is designed as a low-voltage rail.

[0037] In particular, the conductor device can be designed to provide electrical energy at a DC voltage of less than 60 volts, for example, about 48 volts.

[0038] In a further development, the coupling unit can be configured as a connection unit. The connection unit can, for example, be designed to transmit electrical current and, in particular, the control signal from the conductor assembly to the indirect lighting module, especially to transmit it essentially unchanged. This can be advantageous, for example, if the electrical energy provided by the conductor assembly, for instance, in the case of a low-voltage DC voltage, can be used to operate the indirect lighting module without further conversion. Furthermore, the above configuration can also be useful, for example, if the indirect lighting module can directly use or interpret the control signal present at the conductor assembly.

[0039] In another embodiment, the rail is designed as a high-voltage rail, in particular a mains voltage rail.

[0040] In particular, the conductor assembly can be designed to provide electrical energy at an alternating current voltage, especially a nominal electrical voltage of approximately 220 to approximately 240 volts, for example 230 volts.

[0041] In a further training system, the coupling unit can be designed as an adapter unit, which may, for example, include a converter. Thus, the coupling unit can additionally enable a conversion of the electrical energy supplied at the conductor device, such as a change in current type and / or nominal voltage.

[0042] In particular, the adapter unit may include electronic devices for processing and / or interpreting the control signal received from the conductor device.

[0043] In a further development, the indirect lighting module can be operated by means of electrical energy at a first electrical voltage, the conductor device in the inner area is provided for the supply of electrical energy at a second electrical voltage, which is higher than the first electrical voltage, and the coupling unit designed as an adapter unit is set up to receive electrical energy from the conductor device in the inner area and to provide the electrical energy for the supply of the indirect lighting module at the first electrical voltage.

[0044] The rail can also be designed for suspended mounting, particularly on a ceiling or other building component or structure. The simple electrical connection of the indirect lighting module can simplify installation work, for example, when working above head height.

[0045] In a further development process, the indirect lighting module can be inserted into a receiving area of ​​the track, which is formed in a cross-sectional profile of the track facing away from the inner area. This allows the indirect lighting module to be arranged on the track in a simple, reliable, precise and aesthetically pleasing manner to create indirect lighting, especially upwards towards the ceiling of a room.

[0046] In one embodiment, the receiving area is a rear area of ​​the rail in the operating state of the lighting arrangement, wherein the rear area and the inner area are adjacent to each other and are separated from each other by the web.

[0047] In particular, the indirect lighting module can be mechanically coupled to the rail in such a way that, when coupled to the rail, it is movable along its longitudinal direction relative to the rail. This allows for positional adjustment even when the indirect lighting module is mounted on the rail. For example, to mechanically couple the indirect lighting module to the rail, the indirect lighting module and / or the rail can have means that allow the indirect lighting module to be clipped or snapped into the rail. Such a mechanical coupling is relatively easy to implement.

[0048] In one embodiment, the indirect lighting module is designed to be electrically coupled to at least one extension indirect lighting module in such a way that the extension indirect lighting module can be supplied with electrical energy via the coupling unit through the indirect lighting module.

[0049] In a further training, the indirect lighting module is set up to be coupled with the extension indirect lighting module in such a way that the extension indirect lighting module can be controlled via the indirect lighting module according to those control signals by means of which the control of the indirect lighting module is carried out.

[0050] In particular, it may be provided that the extension indirect lighting module can be controlled by means of a signal which can be provided by the coupling unit or by the indirect lighting module by interpreting the control signal provided at the conductor device and can be forwarded from the indirect lighting module to the extension indirect lighting module.

[0051] Furthermore, in other configurations, more than one extension indirect lighting module can be coupled with the indirect lighting module.

[0052] The use of one or more extension indirect lighting modules thus enables the provision of long, continuous indirect lighting, for example, a long indirect light strip along a track, without requiring a separate coupling unit for each indirect lighting module. Instead, the power supply and preferably the control of interconnected, electrically coupled indirect and extension indirect lighting modules are achieved via a single coupling unit. This can help to save costs and installation effort.

[0053] For example, the coupled indirect and extension indirect lighting modules can be controlled together via a common address, such as using the DALI protocol.

[0054] In one embodiment, the lighting module or unit, which is provided in addition to the indirect lighting module and can be mounted on and / or coupled to the rail, is designed to provide direct lighting. This lighting arrangement thus allows for the combination of direct and indirect lighting effects.

[0055] The above embodiments and further developments can be combined with one another as appropriate. Further possible embodiments, further developments, and implementations of the invention also include combinations of features of the invention described previously or subsequently with regard to the exemplary embodiments, even if not explicitly mentioned. In particular, the person skilled in the art will also add individual aspects as improvements or additions to the respective basic form of the present invention.

[0056] Furthermore, it should be noted that the above-described designs and further developments in connection with the lighting arrangement can be applied equally to the coupling unit according to the invention, and vice versa. CONTENT OF THE DRAWING

They illustrate embodiments and, in conjunction with the description, serve to explain the principles and concepts of the invention. Other embodiments and many of the advantages mentioned will become apparent with reference to the drawings. The elements of the drawings are not necessarily shown to scale.

[0059] In the figures, identical, functionally equivalent, and equally effective elements, features, and components are each provided with the same reference symbols, unless otherwise stated. DESCRIPTION OF EXAMPLES OF EXECUTION

[0060] A first lighting arrangement 1 is shown Fig. 1 , 2The lighting arrangement 1 is formed with components that are part of a modular track lighting system. The track lighting system is designed such that linear lighting modules and / or low-voltage tracks and / or spotlights can be optionally accommodated and combined within a single track. Additional lighting units can be connected to the low-voltage tracks, which, like the linear lighting modules and spotlights, preferably provide direct lighting. Furthermore, in some versions, the track lighting system offers the option of providing indirect lighting by means of one or more indirect lighting modules. Advantageously, not every single insertable lighting component needs to be equipped with its own converter.

[0061] It should be mentioned that the rail can be designed for installation in a ceiling, mounting on a ceiling and / or suspension from the ceiling of a room, or from another structure.

[0062] First, a lighting arrangement 1 with direct illumination by means of a linear lighting module 11 is described. The arrangement 1 has a rail 3 which, in a fully assembled position, is open towards the visible side S, particularly at the bottom, and has a first inner region 4 and a second inner region 5 located in the rail 3 above the first region 4 and further towards a rear side of the rail 3 facing away from the visible side S. On the rear side, particularly in an upper region of the rail 3 in the fully assembled position, the second region 5 is closed off by a web 3a, from the opposite ends of which flanges or side walls 3b of the profile 3 extend. Inner longitudinal ribs 3c, 3c' of the profile 3 delineate the regions 4, 5 from each other, with a gap between the longitudinal ribs 3c, 3c' providing access to the second region 5 from the first region 4.The rail profile 3 is symmetrical in cross-section with respect to a longitudinal median plane of the profile 3, except for the end sections of the longitudinal ribs 3c, 3c'.

[0063] In the second area 5, conductor rails, each with three poles or conductors, are arranged on both sides along the rail profile 3 and parallel to its longitudinal direction L, forming a conductor assembly 6 with a total of six conductors 6a, 6b, wherein four of these conductors 6a are for supplying electrical energy and two opposing conductors 6b are for supplying control signals. Three of the conductors 6a are preferably configured as phase conductors for supplying three different electrical phases, and a fourth of the conductors 6a is configured as a neutral conductor.

[0064] The ladder assembly 6 could be in one variant, see Fig. 25 , alternatively, for example, five poles or conductors 6a, 6b on each side of the second area 5, and thus a total of ten conductors 6a, 6b, to be able to switch additional emergency lights into a separate phase. Fig. 25 Figure 1 illustrates a rail with such an alternative conductor arrangement. Again, two busbars and a total of at least two conductors 6b for control signals are provided in area 5.

[0065] For example, a DALI signal is provided for control via conductor 6b. However, a control signal based on other control or dimming methods is also conceivable.

[0066] In Fig. 1 and 2Thus, conductors 6a are provided for supplying luminous components with electrical energy and are supplied with electrical current, preferably alternating current at mains voltage, approximately 220-240V, for example 230V, and a mains frequency of, for example, 50 Hz, by a power supply unit (not shown in detail). This will be referred to below as "high voltage".

[0067] The track lighting system and arrangement 1 include luminous components that are operated with electrical energy at a significantly lower voltage, for example, a DC voltage of less than 60V, such as 48V. This will be referred to below as "low voltage".

[0068] The second area 5 of the rail 3, designed as an upper interior space, is configured to receive an adapter unit 7, wherein the adapter unit 7 has a converter that converts the high voltage of the conductors 6a into low voltage for supplying the luminous components, in Fig. 1 , 2 The converter transforms the current of the lighting module 11 and provides the type of current required by the luminous components at low voltage. The converter is arranged within the adapter unit 7. Preferably, the adapter unit 7 also has a device, not shown in detail in the figures, which makes it possible to select the electrical phase to be used from among those provided by conductors 6a and to connect the lighting unit 11 to the selected phase for power supply via the converter.

[0069] The adapter unit 7, when installed, is mostly contained within the second area 5 and essentially has the basic shape of an elongated cuboid with chamfered longitudinal edges on the side facing the web 3a when installed. The adapter unit 7 is designed to be slim and space-saving. For example, see Fig. 2 The height H7 of the adapter unit 7 is approximately H7 = 28 mm and the width B7 of the adapter unit 7 is approximately B7 = 14 mm. In particular, the ratio H7 / B7 is therefore approximately 2. The length of the adapter unit 7 is shown below. Fig. 1 L7 can be approximately 300 mm. Deviations from these values ​​for H7, B7 and / or L7 are possible in various versions; for example, H7, B7 and / or L7 could each deviate by 2 mm above or below the stated values.

[0070] In the area of ​​the longitudinal side surfaces of the adapter unit 7, this unit has a first contact device 1013 with contact elements 13 that can be extended or folded out from the outer surface of the adapter unit 7 to electrically contact one of the conductors 6a. Contact elements 13 can also be provided for receiving the control signal, for example as shown in Fig. 4 The adapter unit 7 is sketched as two central contact elements 13 of a movable arrangement of six contact elements 13, three of which can project from each of the two longitudinal sides of the adapter unit 7. In this way, the adapter unit 7 can be electrically coupled to the conductor assembly 6 in order to receive electrical energy and control signals from the conductor assembly 6. The contact elements 13 can be folded out or in by a mechanism that can be operated by a technician or operator. This is particularly useful in the case of a ten-pole busbar, such as in... Fig. 25 , the contact device 1013 is not necessarily provided with contact elements 13 for contacting each of the ten conductors 6a, 6b, but may nevertheless be equipped with, for example, four or six contact elements 13.

[0071] The adapter unit 7 of the Fig. 1 , 2 The adapter unit 7, inserted into area 5, can be positioned essentially anywhere along the rail 3. Furthermore, it can be moved longitudinally in the direction L when the contact elements 13 are folded in and the conductors 6a and 6b are not in contact.

[0072] Furthermore, mechanical engagement elements 14 are provided in the area of ​​the two longitudinal side surfaces of the adapter unit 7. These elements can also be extended or folded out from the outer surface to mechanically secure the adapter unit 7 by engaging behind the inner longitudinal ribs 3c, 3c' of the rail 3. In addition, further engagement elements, such as latch-like or clip-like elements, may be provided to enable temporary, releasable fixing to facilitate assembly.

[0073] In Fig. 1 , 2 The second area 5 is bounded to the first area 4 by the inner longitudinal ribs 3c, 3c' of the rail 3. These ribs 3c, 3c' form a kind of two-part partition, in the middle of which a gap remains along the entire length of the rail profile 3 as a passage for inserting the adapter unit 7. Fig. 1 , 2The flanges or side walls 3b of the rail 3 extend downwards beyond the ribs 3c, 3c', forming the first area 4.

[0074] The adapter unit 7 in Fig. 1 , 2 On the side facing the visible side S in the installed state, shown in the figures as the underside, it has point-like, pin- or pin-head-like contact elements 17, some of which serve as "current collectors" to provide the electrical supply to the light module 11, while in some variants one or more other contact elements 17 may serve for signal transmission for control purposes.

[0075] For lighting arrangement 1 of the Fig. 1 , 2 A lighting assembly 2 is shown as a luminous component, which is designed as the linear lighting module 11 for direct lighting.

[0076] The lighting module 11 further comprises a double-sided printed circuit board (PCB) 21 on its upper side when installed. Strip-shaped contact elements 18 are formed as conductive traces on the outer main surface of the PCB and serve for electrical coupling with the adapter unit 7 via the contact elements 17 for power supply and control purposes. Light-generating devices designed as LEDs are arranged on the other main surface of the PCB 21. Additional electrical and / or electronic components for operating the LEDs, as well as conductive traces, may also be arranged on the PCB 21.

[0077] In assembling the lighting arrangement 1, the adapter unit 7 is first inserted from below into the second area 5, electrically coupled to the conductor assembly 6 by means of the contact elements 13, for example by twisting an actuating element, and additionally secured mechanically by means of the elements 14. Then the lighting module 11 is inserted from below into the first area 4 below the adapter unit 7 and snapped or clipped into longitudinal grooves 4a behind further longitudinal ribs of the rail 3 using locking or clipping devices 16.

[0078] The locking devices 16, together with corresponding longitudinal ribs and longitudinal grooves 4a, are designed such that the assembly 2 can be clipped / locked into area 4 with relatively little force and can be pulled out of the rail 3 from below. In particular, the lighting module 11 is not fixed in the longitudinal direction L in arrangement 1. This, and the suitable force exerted by the locking / clipping devices 16, allows the lighting module 11 to be moved longitudinally in the longitudinal direction L, thus enabling positional adjustments.

[0079] Current is drawn by the lighting module 11 via a number of conductor tracks 18 attached to the circuit board 21, each of which makes electrically conductive contact with an associated point contact element 17. The strip-shaped contact elements 18 are located on one side of the assembly 2 facing the adapter unit 7 and extend longitudinally L along the rail 3 when the assembly 2 is inserted into the first, lower section 4. Even after electrical coupling, the lighting module 11 can still be moved longitudinally L along the rail 3, while a power supply is ensured as long as the circuit board 21 is positioned at any point below the contacts 17 of the adapter unit 7.

[0080] The control signal, for example a DALI signal or a control signal based on another protocol, is received by the adapter unit 7 from the conductor assembly 6, and the lighting module 11 is operated based on this control signal. In arrangement 1, the control signal can be interpreted by devices in the adapter unit 7, an output signal for controlling the lighting module 11 can be generated, and the output signal can be transmitted to the lighting module 11 via one or more of the contact elements 17. Alternatively, the control signal received by the conductor assembly 6 can be forwarded by the adapter unit 7 to the lighting module 11 via one or more of the contact elements 17 and interpreted by devices in the lighting module 11.

[0081] The rail 3 can be formed from several rail sections that are connected to each other to form a longer linear or angled system of selectable length, which can accommodate a variety of luminous components of the same or different types. If the rail 3 is constructed with several joined sections, each containing conductor rail sections to form the conductor assembly 6, the conductor rail sections forming the conductor assembly 6 can be electrically connected in the second area 5, i.e., in the high-voltage area, by intermediate or connecting pieces (not shown in the figure) for electrical coupling of the corresponding conductors 6a, 6b.

[0082] For example, see Fig. 3 , in a lighting arrangement 1', a first assembly 2 designed as a linear lighting module 11, and one or more further lighting assembly(s) 12, each also designed as a linear lighting module 11a, of which in Fig. 3 Only one is shown, it is intended.

[0083] The modules 2 and 12 are each equipped at their end faces with connecting devices 15 provided for this purpose, such that module 2 can be electrically coupled to one of the other modules 12 at each of its end faces. In this way, module 2, and indirectly the module(s) 12, are supplied with electrical energy provided by the adapter unit 7, in particular with direct current at low voltage.

[0084] Therefore, in a longer lighting arrangement 1', not every section of the rail 3 and not every lighting module 11, 11a requires a separate adapter unit in the upper (high-voltage) rail profile inner area 5. Fig. 3 Several lighting modules 11, 11a, for example a total of three modules, can be supplied by a common adapter unit 7.

[0085] Furthermore, modules 2 and 12 are controlled and operated according to a master-slave principle. Module 2, which is directly coupled to adapter component 7, is considered the "master," to which the further module(s) 12, indirectly coupled to adapter unit 7 via module 2 and devices 15, are subordinate as "slaves." The interpretation of the control signal present on conductors 6b, e.g., as a DALI signal, can be performed by adapter unit 7 or the first module 2 ("master"), whereby an output signal generated by adapter unit 7 or module 2 based on the control signal is passed on to the "slave" module(s) 12 via device 15.In both cases, modules 2 and 12, i.e., lighting modules 11 and 11a, are addressed via a common address, for example, a common DALI address. This address is thus assigned to adapter 7, or to module 11 and indirectly to the connected modules 11a. The extension lighting module 11a receives power and control signals in accordance with the first module 11.

[0086] At the same time, the installed assemblies 2 and 12 can be moved together along the rail 3. Advantageously, the adapter component 7 in the high-voltage area 5 does not need to be loosened and repositioned for this purpose.

[0087] The lighting module 11a of the Fig. 3 The second and subsequent lighting modules 11a are designed analogously to the lighting module 11, except that the circuit boards of the second and subsequent lighting modules 11a are not necessarily double-sided, but can be single-sided and therefore more cost-effective. The circuit board of the lighting module(s) 11a can provide power and operate the LEDs on the inward-facing main surface of the circuit board and supply power and signals via the device(s) 15.

[0088] In particular, modules 11, 11a, which are supplied together - directly ("Master") or indirectly ("Slave") by an adapter 7, are switched in and supplied via the same electrical phase selected by means of the adapter unit 7.

[0089] Fig. 5-13 Figures 1a, 1a' and variants thereof show a lighting arrangement. The arrangement 1a' of the Fig. 5 One rail has 3 corresponding to that in Fig. 1-3 up. In Fig. 5 The exemplary sketched lighting units 211a and / or 211b are connected to the rail 3 via a module 2 with a smaller rail 9.

[0090] The second, smaller rail profile 9 is accommodated in the first section 4. The second, smaller rail 9 is supplied with low voltage by an adapter unit 7' located above it in both the installed and operating state and is designed to accommodate, at least in sections, and / or couple with the lighting units 211a, 211b (shown only schematically). Furthermore, the rail 9 provides power to the lighting units 211a, 211b and can also supply control signals to them. The lighting units 211a, 211b are equipped, for example, with suitable devices for electrical and, for example, mechanical coupling to the rail 9. The lighting units 211a, 211b are preferably slidably coupled to the rail 9 and are specifically designed for direct illumination.

[0091] Furthermore, according to one embodiment, the lighting arrangement 1a' has a coupling unit 8', which is hereinafter also referred to as the connecting unit 8', and which enables electrical coupling of the rail 9 and the adapter unit 7'. The assembly 2, which can be received in the first area 4 of the rail 3, is formed here with the rail 9 and the connecting unit 8'. Preferably, the assembly 2, in particular the rail 9, is mechanically lockable to the rail 3 or clipped into the rail 3, for which suitably designed means, not shown in detail in the figures, may be provided. The mechanical fastening of the assembly 2 formed with the rail 9 and the connecting unit 8' is analogous to the locking or clipping.The clipping mechanism of assembly 2 in arrangements 1 and 1' is designed such that even after locking or clipping, the rail 9 and the connecting unit 8' can be moved longitudinally L along the rail 3. Similarly, in arrangement 1a', locking assembly 2 to the rail 3 and releasing it from this locking position requires relatively little force, allowing for quick and easy locking and releasing.

[0092] The adapter unit 7' is constructed like the adapter unit 7 with regard to its basic shape and dimensions, mechanical fixing in the outer rail 3 and electrical coupling with the conductor assembly 6, so reference is made to the above descriptions in this respect. A converter is arranged inside the adapter unit 7'.

[0093] Unlike adapter unit 7, adapter unit 7' is not equipped with point current collectors for supplying light modules on its lower side, which faces the visible side S in the mounted state. Instead, adapter unit 7' has the Fig. 5-13 On the underside of the adapter unit 7', i.e., the side facing the rail 9 when the adapter unit 7' and the assembly 2 comprising the rail 9 and the connecting unit 8' are inserted into the rail 3, a contact device 1027 with several strip-shaped contact elements 27 is provided. When the assembly 2 is inserted into the rail 3, each of the contact elements 27 can be brought into electrically conductive contact with an associated contact element 28 of the assembly 2. When the adapter component 7' is inserted into the second area 5, the strip-shaped contact elements 27 extend with their longitudinal direction parallel to the longitudinal direction L of the rail 3.

[0094] The first low-voltage busbar module, forming the assembly 2 and which can be inserted under the adapter unit 7' into the section of the rail profile 3 shown, has a through-opening 10' on the upper side of the rail 9 when mounted, the through-opening 10' being incorporated into a web 9a of the rail 9. After the adapter unit 7' and the assembly 2 are inserted into the rail 3, the web 9a faces the adapter unit 7'.

[0095] A contact arrangement of the connecting unit 8' is formed with the contact elements 28. The multiple contact elements 28 of the Fig. 5 , 6 are arranged on a protruding contact section 8a' of the connecting unit 8' and are designed as point-like, pin- or pin-head-like contact elements 28 on the top side of the contact section 8a'.

[0096] By inserting the contact section 8a' into the through-hole 10', the point contacts 28 of the connecting unit 8' can each be brought into electrical contact with one of the conductor tracks 27 of the adapter 7' placed above, in order to electrically couple the assembly 2 with the adapter unit 7'.

[0097] The connector 8' serves as a coupling unit and subsequently ensures the supply to the assembly 2, which is designed as a low-voltage busbar module. Here, the busbar 9 is equipped with a conductor assembly 26 comprising low-voltage conductors 26a and control signal conductors 26b along the longitudinal direction of the busbar 9. A cross-section of the busbar 9 is defined in Fig. 9 shown and also in the variant of Fig. 5 , 6 in this form and configuration.

[0098] The low-voltage rail modules 2 are thus equipped to accommodate and supply power to the lighting units 211a, 211b to be operated at low voltage, as well as to supply the lighting units 211a, 211b on the rail 9 with control signals.

[0099] In particular, it is provided that the conductor 26a of the conductor assembly 26 in the interior of the rail 9 is supplied with electrical energy at low voltage, for example a DC voltage of 48V, and with one or more control signals, for example a DALI signal, via the adapter unit 7' and the connection unit 8'.

[0100] The supply of electrical current at low voltage via the adapter unit 7', starting from the supply of mains voltage via the conductor assembly 6, is effected by means of a converter of the adapter unit 7' as described above for arrangements 1, 1'. The low voltage for the power supply of the lighting units 211a, 211b is then passed on to the connection unit 8' via, for example, two contact elements 27, 28 each. The selection of an electrical phase using the adapter unit 7' is also possible as described above.

[0101] Control signals provided on the conductors 6b of the conductor assembly 6, such as a DALI signal, are forwarded unchanged to the connection unit 8' via one or more further corresponding contact elements 27, 28 in the arrangement 1a'.

[0102] For example, on both sides of the inner area 9b of the rail 9, one conductor 26a per side can be provided for power supply and another conductor 26a per side for control. The lighting units 211a, 211b that can be installed there can be addressed separately with control signals, for example via their own, separate DALI addresses.

[0103] The connecting unit 8' is configured to receive electrical energy and control signals from the adapter unit 7' and to feed the electrical energy received via contact elements 27, 28 into the conductors 26a of the conductor assembly 26 of the rail 9, as well as the control signals transmitted from the adapter unit 7' via the further contact elements 27, 28 into the conductors 26b. For this purpose, the connecting unit 8' has a contact device for electrical coupling with the conductor assembly 26. Furthermore, the connecting unit 8' can be mechanically locked or clipped to the rail 9 of the assembly 2.

[0104] Variants of the lighting arrangement 1a' according to further embodiments show the Fig. 7-13 Except for the differences described below, the above statements regarding the Fig. 5 , 6 also on the lighting arrangements 1a, 1a" of the Fig. 7-13 Application.

[0105] The lighting arrangement 1a of the Fig. 7-12 The rail 3, an adapter unit 7', and a module 2, each module having lighting units, e.g., 211a, 211b, coupled to the rail 3 by means of the module 2. For details regarding the design of the rail profile 3 and the adapter unit 7' and their functions, please refer to the above descriptions.

[0106] In the variants of, assembly group 2 includes Fig. 7-13 in turn a second rail 9 with a ladder device 26 arranged in its interior area 25, which is divided into two parts and arranged on both sides of the interior area 25, see Fig. 9 , and a connecting unit 8, shown enlarged in Fig. 12 .

[0107] The connecting unit 8 in Fig. 7-13 is of an elongated, box-like outer shape and is designed to be arranged essentially entirely within the inner area 25 of the rail 9, such that the conductors 26a of the conductor assembly 26 are located laterally to the connecting unit 8, see Fig. 9-11 A first contact device 1030 with contact elements 30, see Fig. 12 The connecting unit 8 is designed to come into electrically conductive contact with the conductors 26a, 26b of the conductor assembly 26 extending along the rail 9 when the connecting unit 8 is inserted into the inner area 25. Elastically spring-loaded locking elements 31 serve to preferably allow the connecting unit 8 to be detachably clipped into the rail 9 for the mechanical coupling of components 8 and 9.

[0108] The connecting unit 8 has in Fig. 7-13 also the function of a coupling unit 8, which enables the electrical coupling of the rail 9 with the adapter unit 7' for the transmission of power and control signals. The coupling unit 8 has a contact section 8a which, when the coupling unit 8 is inserted into the rail 9, is inserted into a through-opening 10 in the web 3a of the rail 3. A second contact device 1028 with - in is attached to the contact section 8a. Fig. 12 Three point-like, pin- or pin-head-like contact elements 28 are provided, for example. The contact elements 28 are designed and arranged to each come into electrically conductive contact with a corresponding strip- or web-shaped contact element 27 of the adapter unit 7'.

[0109] The contact section 8a is in the Fig. 7-13 , in contrast to the plate-like contact section 8a' in Fig. 6 , formed with a smaller base area and a larger overhang beyond the remaining top surface of the connecting unit 8, for example of a cylindrical shape, and has the three contact elements 28. An outer outline of the contacting section 8a preferably corresponds to an inner cross-sectional shape of the through-opening 10.

[0110] Furthermore, it should be noted that in Fig. 7-11 and 13 The adapter unit 7' is provided with a projection 7a' approximately centrally with respect to its longitudinal axis and on its upper surface, which in the mounted state points towards the web 3a of the rail 3. This projection can be part of a body and / or housing of the adapter unit 7' and, in other variants, can be equipped with contact elements instead of the contact elements 27, whereby, however, in Fig. 7-11 , 13 Contact elements are not present on the projection 7a'. Alternatively, the projection 7a' could be omitted on the adapter unit 7'.

[0111] In one variant of arrangement 1a, at least one further assembly 12 can be provided, which is supplied with electrical energy and control signals via assembly 2, provided by the adapter unit 7'. Such a lighting arrangement 1a" is shown in Fig. 13 shown. Analogous to assembly 2, assembly 12 shows in Fig. 13 a rail 9, with which one or more lighting units, e.g. 211a, 211b (in Fig. 13 (not shown), connectable and / or at least partially receptive to the further rail 9. The extension rail 9 of the assembly 12 in Fig. 13 also features a ladder device 26 analogous to assembly 2 in Fig. 5-12 In the area of ​​a joint 1202, the assemblies 2, 12 are coupled to each other in such a way that the corresponding conductors 26a, 26b of the two rails 9 are electrically in contact with each other at their adjacent end faces. For this purpose, suitable coupling pieces (not shown in detail) can be provided at the joints 1202.

[0112] In this way, several low-voltage track modules in the form of assemblies 2 and 12 can be inserted adjacent to each other into track 3 and electrically connected. Assembly 12 of the Fig. 13 It does not have a connection unit 8 or 8'. Therefore, it is sufficient to connect only one low-voltage busbar module, i.e., assembly 2, electrically via adapter unit 7' to the high-voltage busbar 3. The low-voltage busbar modules 2 and 12 are all connected to the same phase, which can be selected using adapter unit 7'. Electrical current for supplying the lighting units 211a and 211b, as well as control signals, are routed via conductors 26a and 26b at the coupling point 1202, allowing the lighting units located on the extension busbar 9 of assembly 12 to be individually controlled via their own addresses.

[0113] Out of Fig. 13 It is evident that rail 3 can be formed with several end-connected rail profile sections to create a longer linear system, for example by means of suitable connecting pieces. Not every section of rail 3 and not every rail section 9 requires a separate adapter unit 7' in the upper area 5.

[0114] The arrangements 1a, 1a', 1a" each also allow, after the insertion of the adapter unit 7' and the assembly 2 and, if applicable, the assembly 12 into the rail 3, the assembly 2 or the assemblies 2 and 12, including rails 9 and connecting unit 8 or 8', to be moved relative to the adapter unit 7'.

[0115] Fig. 14-18 Figure 1b shows a lighting arrangement according to an exemplary embodiment and a variant 1b' thereof, which can be suspended and, in addition to luminous components for direct lighting, can be equipped with indirect lighting. The lighting arrangement 1b, 1b' of Fig. 14-18 It can, for example, be suspended from the ceiling of a room or another component of a building, or from another structure. Indirect lighting is implemented in arrangements 1b and 1b' as described below.

[0116] The lighting arrangement 1b, 1b' comprises a rail 3", which is analogous to the rail profile 3 in Fig. 1-3 , 5-13The rail profile 3" has a region 4 and an inner region 5, the design and function of which are described above. However, the rail profile 3" differs from the rail profile 3 in that, on the rear side of the rail 3" facing away from the visible side S, and thus on the rear side of the web 3a, an additional receiving area 44 is provided. The receiving area 44 is formed in the cross-sectional profile of the rail 3" as a flat channel facing away from the second region 5. The cross-sectional shape of the rail 3" is essentially symmetrical about a longitudinal center plane, except for the end sections of the longitudinal ribs 3c, 3c', which differ.

[0117] The receiving area 44 serves to receive an assembly which is designed as an elongated indirect lighting module 40, which is inserted into the receiving area 44 and, in the assembled state, can emit light essentially upwards, i.e., for example towards the ceiling of the room.

[0118] The 3" rail in Fig. 14-18 is equipped with a three-phase, or alternatively a five-phase, conductor assembly 6 designed for mains voltage, analogous to that described above for the rails 3, 3'. The web 3a limits the inner area 5 equipped with the conductor assembly 6 upwards and thus separates the receiving area 44 from the inner area 5. Upwards, i.e., towards the rear of the rail 3", opposite the visible side S, it is provided with one or more through-openings 50, see Fig. 17 , equipped in the jetty 3a.

[0119] Furthermore, an adapter unit 7" is provided which can be inserted into the rail 3" analogously to the adapter units 7, 7', and which is designed analogously to the adapter units 7, 7' with regard to its basic shape, mechanical fixing and electrical coupling in the area 5, with differences being described below.

[0120] In addition to the first contact device 1013, the adapter unit 7" has a second contact device 1017a with point contact elements 17a on the upper surface of the adapter unit 7". The contact elements 17a are pin-like or pin-head-like and protrude from an upper surface of a projection-like contact section 7a", which is essentially the same as the projection 7a'. Fig. 13 The contact section 7a" is arranged essentially centrally with respect to the longitudinal extent of the adapter unit 7" and is provided on the upper side of the adapter unit 7" facing away from the visible side S and towards the web 3a when installed.

[0121] The contact section 7a" can be inserted into the opening 50 for electrical coupling of the indirect lighting module 40 and the adapter unit 7". Thus, the contact elements 17a, see Fig. 14 , through the opening 50 and protrude upwards from it. A body section of the contact section 7a" preferably substantially fills the through-opening 50, thereby closing it after the adapter unit 7" is inserted.

[0122] The adapter unit 7" is, like the adapter unit 7, 7', by selecting a suitable opening 50 or by placing the opening 50 at the desired longitudinal position, basically freely positionable along the rail 3", but after the contacting section 7a" has been inserted into the opening 50 it can no longer be moved longitudinally.

[0123] The first indirect lighting module 40, which can be inserted into the rail 3", has a double-sided printed circuit board 41 ('PCB') which, on its underside, can be electrically coupled to the protruding contact elements 17a of the adapter unit 7" via a contact device 1047 with track- or strip-shaped contact elements 47. Further indirect lighting modules can each be inserted as extension indirect lighting modules 40a adjacent to the end face of the first indirect lighting module 40 in the receiving area 44 and connected to the first indirect lighting module 40 according to a master / slave principle, whereby the indirect lighting module 40 can be considered the "master". The connection can be made at a joint 4040 by means of connection devices not shown in detail, see Fig. 18 . The other indirect lighting modules 40a or "slaves" can have at least a single-sided circuit board instead of the double-sided circuit board 41, which can contribute to cost savings and simplified manufacturing.

[0124] The indirect lighting module 40a is supplied with electricity via the indirect lighting module 40, e.g. as in the arrangements of the Fig. 1-4 A low voltage for the operation of the indirect lighting modules 40, 40a is provided by the adapter unit 7", which includes a converter. The electrical phase provided by the conductor assembly 6, which is to be used for the power supply of the indirect lighting modules 40, 40a via the converter, can also be selected by means of the adapter unit 7", as described above.

[0125] The indirect lighting modules 40 and 40a are controlled in an analogous manner to the direct lighting modules 11 and 11a, whereby the indirect lighting modules 40 and 40a are addressed and controlled jointly via a common address, e.g., a DALI address. The control signal provided on the conductors 26b of the conductor assembly 6 is interpreted by devices in the adapter unit 7" or, alternatively, by devices on the circuit board 41 of the "master" indirect lighting module 40, and an output signal for control is generated based on this interpretation. The contact device 1017a is configured, for example, to transmit the output signal generated based on the interpretation of the control signal in the adapter unit 7" or to forward the control signal received by the adapter unit 7" from the conductor assembly 6. In both cases, the output signal resulting from the interpretation is transferred at the interface 4040.The output signal can be implemented, for example, using pulse width or pulse-pause modulation.

[0126] A cumbersome, separate wiring of the indirect lighting module 40 on the construction site can be avoided with the help of the contact devices 1017a, 1047 described above and their interaction. A relatively small through-opening 50 is created in the web 3a in the area of ​​the top of the rail 3". The opening 50 can either be prefabricated or flexibly created on-site at the desired position. The freely positionable adapter 7", which is initially movable with the contact elements 13 folded in, is then positioned in the rail 3" under the recess 50. Indirect lighting modules 40 can then be inserted quickly, variably, and flexibly without much effort. Furthermore, with a given electrical connection, the indirect lighting module 40, and possibly additional indirect lighting modules 40a as "slaves", still retains longitudinal movement L relative to the adapter unit 7".For example, another module 40a can be provided at each end of module 40, and an indirect light strip of greater length is also conceivable.

[0127] The adapter unit 7" serves as a coupling unit 7" in the manner described above for coupling the conductor assembly 6 with the indirect lighting module 40.

[0128] The adapter unit 7" is designed to supply the indirect module 40 and, if applicable, in arrangement 1b', further indirect modules 40a in the receiving area 44 as "slaves". In addition to the adapter unit 7", in Fig. 14-18 another, in Fig. 15 , 17, 18 The non-visible adapter unit 7 is inserted into the inner area 5 of the rail 3" and as described in the Fig. 1-4 described. By means of the further adapter unit 7, one or more linear lighting modules 11, 11a can be connected as assemblies 2, 12 analogously. Fig. 1-3 to be supplied in order to implement direct lighting, i.e., in particular from the visible side S into the room below, by means of the lighting arrangement 1b, 1b'. With such an arrangement 1b, 1b', continuous direct and indirect light bands can, for example, be created simultaneously, which can be moved separately along the track 3".

[0129] In Fig. 14, 16 The front face of the rail 3" can be seen with two adapter units 7, 7" as examples - one for direct and one for indirect modules - whereby, with the exception of the contact elements 17, only the foremost adapter unit 7" is visible and the adapter unit 7 arranged behind it is concealed.

[0130] As with the lighting arrangements, which are based on the Fig. 1-13 As described above, in the exemplary embodiment of the Fig. 14-18 The area 4, which is provided for the at least partial and preferably substantially complete accommodation of the assembly(s) 2, 12 preferably designed for direct lighting, is designed as a front area 4 of the rail 3" in the operating state of the lighting arrangement 1b, 1b'.

[0131] The front of the lighting arrangement 1b or 1b' corresponds to its visible side S, in particular its underside in a mounted state.

[0132] The receiving area 44 for the at least partial, preferably substantially complete, receiving of the indirect lighting module 40 and, if applicable, the extension indirect lighting module 40a, is designed as a rear area 44 of the rail 3". The receiving area 44 and the inner area 5 are thus arranged on different sides of the web 3a, with the inner area 5 being provided between the web 3a and the area 4. In the exemplary embodiment of the Fig. 14-18 thus adjacent to each other and separated from each other by footbridge 3a.

[0133] It should be mentioned that the contact devices 1017a, 1047 described above with reference to exemplary embodiments enable a simple and quick, movable electrical coupling which advantageously requires little effort and time during assembly and is also space-saving.

[0134] In a modified version, however, the contact devices 1017a, 1047 can be replaced by a cable connection, with a sufficient cable length to allow the indirect lighting module 40 and, if applicable, the extension indirect lighting module 40a to be moved relative to the adapter unit 7". The cable connection can, for example, be a flexible cable that is connected at one end to the contact section 7a" and at the other end to the indirect lighting module 40, and extends through the opening 50.

[0135] The above outlines some possibilities for constructing a lighting arrangement based on the track lighting system described above, whereby the various assemblies, lighting modules, lighting units, indirect lighting modules, and track profiles described above can be combined in many ways to meet the lighting requirements in different applications.

[0136] In particular, the indirect lighting module(s) 140, 140a can be made of Fig. 14-18 with reference to Fig. 1-13 The described direct lighting modules 11, 11a or lighting units 211a, 211b can be combined in a variety of ways. For example, both direct and indirect lighting strips can be created in this way, which, when in use, can be moved independently of each other relative to the respective adapter unit 7" or 7 or 7'.

[0137] As described above, for extension rails 9, see Fig. 13 , or extension modules 11a, 40a, see Fig. 3 and 18 , no separate adapter unit is necessary.

[0138] However, a separate adapter unit is preferably provided for each of the differently configured assemblies 2, 12 and for the indirect lighting. For the lighting modules 11, 11a, for the low-voltage rails 9 with lighting units 211a, 211b, and for the indirect lighting using the indirect lighting modules 40, 40a, the track lighting system provides a separate adapter unit 7, 7', 7" for each. In particular, with regard to their basic shape and dimensions, as well as their mounting in the second area 5 and their contact with the conductor assembly 6, the adapter units 7, 7', 7" are essentially analogous.

[0139] Thus, for example, a first adapter unit 7" is preferably used for a lighting arrangement with indirect lighting modules 40, 40a, and a second, independent adapter unit 7" is used for additional direct lighting modules 11, 11a in the track 3", for example, next to the first adapter unit 7". To combine the indirect lighting modules 40, 40a with a module 2 with the low-voltage track 9, a second adapter unit 7' can be used in addition to the adapter unit 7"". This allows for flexible combination of direct or indirect lighting components while simultaneously limiting the complexity of the adapter units 7, 7', 7" in terms of electrical and control engineering.

[0140] Furthermore, the rail system can provide an independent adapter unit, not shown in the figures, for spotlights or other lights not shown.

[0141] It is conceivable, for example, to provide contact elements 17a for supplying an indirect lighting module 40 and contact elements 17 for supplying modules 11 and 11a simultaneously on the adapter or coupling unit 7". Similarly, it would be conceivable to provide contact elements 17a for an indirect module 40 on the adapter unit 7'. In such a modification, only one adapter unit is required instead of two, although this one is more complex in terms of electrical and control technology, especially if direct and indirect lighting are to be controlled independently of each other.

[0142] The adapter units 7, 7" described above can each be equipped with different numbers of contact elements 17 or 17a. For example, the adapter unit 7 or 7" could have three or four point contact elements 17 or 17a, with a corresponding number of contact elements 18 or 47 being provided.

[0143] For example, three pin contacts 17 or 17a can be used in various configurations and embodiments to create the possibility of a so-called "tunable white" function, with the pin contacts 17 and 17a providing positive and negative current contacts for this purpose. In this case, the contact elements 17 and 17a can have the following configuration: first contact element positive (cold); second contact element positive (warm); third contact element negative.

[0144] In a variant where the "Tunable White" option is not available, it may be sufficient to equip the adapter units 7, 7" each with only two contact elements, with the following assignment: first contact element positive, second contact element negative.

[0145] The above describes a track lighting system that allows for the combinable mounting of movable spotlights, lighting modules and low-voltage tracks, which themselves can accommodate further lighting units, particularly in a movable manner, in a three-phase or five-phase track.

[0146] A lighting arrangement 100 according to a further embodiment, and a variant 100' thereof, show Fig. 19-24 The lighting arrangement 100 comprises a rail 109, at least one indirect lighting module 140 for providing indirect lighting, and an adapter or coupling unit 108.

[0147] Rail 109 is designed for coupling and / or at least partially accommodating one or more lighting units 111a and / or 111b, which are in Fig. 19 are shown schematically and can be of different types, for example they can be designed as linear modules 111b or spots 111a.

[0148] Rail 109 has a first section 144 and a second section 125, see the cross-sectional view of the Fig. 23 . In the inner, in Fig. 23 In the lower section 125, a conductor assembly 126 is provided along the rail 109 for supplying at least electrical energy to the lighting unit(s) 111a, 111b. The conductor assembly 126 extends parallel to a longitudinal direction L' of the rail 109. Fig. 23, 24 It is shown that the conductor assembly 126 is designed with two busbars, each with two conductors 126a, 126b, one busbar on each side of the inner area 125, laterally within it, wherein the conductors 126a serve to supply the electrical current and the conductors 126b serve to supply a control signal, such as a DALI signal, whereby a control signal based on, for example, another protocol or dimming method is also conceivable. If, for example, a control signal is not desired, the conductor assembly 6 could alternatively be designed with only one busbar on one side, and with a total of two conductors.

[0149] The rail 109 is designed as a low-voltage rail, for example for supplying power to the lighting units with a DC voltage of less than 60V, for example 48V, which is fed into the conductor assembly 126 from a feed-in unit not shown.

[0150] The adapter unit 108, which can also be referred to as a coupling or connection unit, serves to electrically couple the conductor assembly 126 with the indirect lighting module 140. It can be inserted into the inner area 125 of the rail 109 and coupled to the rail 109. When the coupling or adapter unit 108 is installed, the conductors 126a and 126b are arranged laterally to the side of the unit 108.

[0151] The in Fig. 20 The coupling or adapter unit 108, shown separately, has a first contact device 1130 with contact elements 130 arranged on the longitudinal sides of the unit 108. The contact elements 130 are arranged and configured to make electrically conductive contact with each of the conductors 126a, 126b. Furthermore, the coupling unit 108 has elastically spring-loaded locking elements 131 on its longitudinal sides, by means of which the unit 108 can be clipped into the rail 109 from its visible side S for mechanical coupling with the rail 109.

[0152] The adapter unit 108 is thus designed to tap current from the conductors 126a and preferably also control signals from the conductors 126b by means of the contact elements 130 on the side of the conductor assembly 126, to redirect these upwards by 90° and to make them available to the indirect lighting module 140.

[0153] A cross-sectional shape of the rail 109 is formed with a web 109a and side walls or flanges 109b, wherein the web 109a extends between the flanges 109b. The web 109a delimits the inner, second area 125 of the rail 109, which is equipped with the conductor device 126.

[0154] The rail 109 is suspended to form the lighting arrangement 100, for example in a building, for example by suspending the rail 109 from a ceiling, from another part of the building, or from another structure.

[0155] The first area 144, hereinafter also referred to as receiving area 144, is located on the rear side of the rail 109, facing away from a visible side S in the assembled state, and thus on the rear side of the web 3a. The receiving area 144 is formed in the cross-sectional profile of the rail 109, in particular as an upper part of a channel facing away from the web 109a and the inner area 125. Starting from its opening towards the web 109a, the channel has two sections of different widths and is narrower towards the web 109a due to inwardly projecting, lateral steps.

[0156] The receiving area 144 serves to receive a component designed as an elongated indirect lighting module 140, which - in Fig. 23, 24 from above - can be inserted into the recording area 144. When mounted, the indirect lighting module 140 inserted into the first area 144 can emit light upwards, for example towards the ceiling of the room.

[0157] To supply the indirect lighting module 140 with electrical current and preferably with control signals, the coupling unit 108 has a contact section 108a. The rail 109 is provided with a through-opening 110 in the area of ​​the web 109a, see Fig. 19 When the coupling unit 108 is inserted into the rail 109, the contact section 109 is inserted into and guided through the through-opening 110, such that the upper part of the contact section 108a passes through the through-opening 110 to supply the indirect lighting module 140 with electrical current and preferably also with the control signals.

[0158] The indirect lighting module 140 has a double-sided printed circuit board 141. On one main surface of the printed circuit board 141, which faces the web 109a when inserted into the receiving area 144, elongated, strip-shaped contact elements 147 of a contact device 1147 of the module 140 are formed, extending parallel to the longitudinal direction L' and forming conductive traces. On the other, opposite main surface, the printed circuit board 141 is equipped with light-generating devices, which are preferably designed as LEDs.

[0159] A second contact device 1128 with several, in the example shown three, point-like, pin- or pin-head-like contact elements 128 is arranged on the contact section 108a of the adapter unit 108, which protrude from an upper surface of the contact section 108a in the mounted state, see Fig. 20 .

[0160] When the coupling unit 108 is inserted, the second contact device 1128, comprising the contact elements 128, comes into electrically conductive contact with the contact device 1147 of the indirect lighting module 140, comprising the contact elements 147. In particular, each contact element 128 contacts one of the track-like contact elements 147.

[0161] With the described design and the interacting contact devices 1128 and 1147, complex wiring of the indirect lighting module 140 is unnecessary; the electrical connection of the conductor assembly 126 to the indirect lighting module 140 is simple and time-saving. The relatively small through-hole 110 can be prefabricated in the rail 109 or flexibly installed on site. The indirect lighting module 140, and possibly additional indirect lighting modules 140a (see variant of the Fig. 22 , can be inserted quickly, variably and flexibly without much effort.

[0162] In addition, the point contact elements 128 can slide on the track-like contact elements 147 in the contacting state, which allows the indirect lighting module 140 to be displaced relative to the coupling or adapter unit 108 in the inserted state.

[0163] Fig. 22 This illustrates that in a lighting arrangement 100' according to one variant, the indirect lighting module 140 can form a first indirect lighting module 140, which can be electrically coupled to at least one extension indirect lighting module 140a. For this purpose, the extension indirect lighting module 140a can be inserted into the receiving area 144 in the same way as the indirect lighting module 140. In this way, a joint 1414 is formed between the modules 140 and 140a, which is Fig. 22 is not yet completely closed. At the joint 1414, modules 140 and 140a can be electrically coupled to each other in order to also supply the extension indirect lighting module 140a with electrical energy via the indirect lighting module 140 through unit 108.

[0164] Modules 140 and 140a are controlled and operated according to a master-slave configuration, with module 140a acting as the "slave" and subordinate to module 140 as the "master". In other words, the extension indirect lighting module 140a is controlled according to the control signals that the first indirect lighting module 140 receives from the adapter unit 108, and the first indirect lighting module 140 is controlled and operated accordingly.

[0165] The preferably double-sided printed circuit board 141 ("PCB") of the first indirect lighting module 140 enables, in the exemplary embodiment of the Fig. 19-24 The module 140 not only supplies power but also interprets control signals transmitted via contact devices 1130, 1128, and 1147 from the conductor assembly 126 to the first module 140 via the coupling unit 108, thus enabling control functions such as dimming. The module 140a ("slave") is also controlled via the end-face coupling with the module 140a, just like the module 140. The first indirect lighting module 140 ("master") evaluates the control signal transmitted by the conductors 126b. Based on this control signal, these devices generate, for example, an output signal, which is used by the module 140 to control itself and is also passed on at the joint 1414 to the extension module 140a for its control.The output signal is, for example, a signal correlated with the dim level, such as one based on pulse-width modulation or pulse-pause modulation. Modules 140 and 140a can therefore be controlled via a common address.

[0166] The additional extension indirect lighting module(s) 140a can be connected to module 140 according to the master / slave principle described above and therefore do not require their own coupling unit. At least one extension module 140a at each end of module 140 is possible.

[0167] It should be noted that in an equally advantageous variant of the embodiment of the Fig. 19-24 Instead of contact devices 1147, 1128, a cable connection can be provided, analogous to the above for contact devices 1017a, 1047. Fig. 17described. The cable connection can, for example, be formed with a flexible cable which is connected at one end to the contact section 108a and at the other end to the indirect lighting module 140 and extends through the opening 110.

[0168] Rails 3, 3', 3", 9, 109 can each be made, for example, from a metal material, such as aluminum. Aluminum rails can be easily worked on-site by installers using relatively simple tools.
