Description

AREA OF INVENTION

[0001] The invention relates to lighting arrangements with a rail profile or 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] CN 211 694 555 U further describes a lighting arrangement comprising a guide rail open on the underside, a lighting assembly, and a component connected to the lighting assembly via a flexible cable. Within the guide rail, insulating elements are provided to accommodate electrified strips. The lighting assembly is equipped with rotatable clips for mounting on the guide rail. The component connected to the lighting assembly via the cable can be inserted into the guide rail by means of a cylindrical section of this component. By rotating this component, electrically conductive elements are brought into contact with the electrified strips of the guide rail. The lighting assembly can then be attached to the underside of the guide rail and moved back and forth along the guide rail.

[0008] Although such conventional track systems already offer an advantageous, high degree of flexibility in designing a lighting solution adapted to individual circumstances, it has been shown that an improvement in the flexibility of such lighting arrangements, while maintaining a relatively simple and cost-effective design, would be desirable. SUMMARY OF THE INVENTION

[0009] Against this background, the invention aims to propose a further improved lighting arrangement that offers improved flexibility, is comparatively simple and economical in design, and enables simple and quick assembly.

[0010] According to the invention, this problem is solved by a lighting arrangement with the features of claim 1 and / or by a lighting arrangement with the features of claim 6.

[0011] A lighting arrangement is proposed that includes: an assembly designed as a lighting module or with which at least one lighting unit can be coupled and / or through which at least one lighting unit can be received at least section by section; a rail profile with a first area for receiving the assembly at least section by section and with a second area in which a conductor device for providing at least electrical energy is provided along the rail profile; and an adapter unit which can be received at least section by section in the second area of ​​the rail profile and is designed to be electrically coupled to the conductor device in the second area, to receive electrical energy from the conductor device and to provide the assembly with electrical energy for supplying the lighting module or the lighting unit.

[0012] In this arrangement, the adapter unit and the assembly for electrical coupling are configured such that the assembly can be displaced relative to the adapter unit inserted into the second area of ​​the rail profile along a longitudinal direction of the rail profile.

[0013] One of the underlying ideas of the invention is to further increase the flexibility and versatility of the lighting arrangement by, firstly, allowing the adapter unit to be mounted at a selectable position along the rail profile, and secondly, allowing the assembly that provides the luminous components, or for which they are coupled or mounted, to be varied in its position along the profile rail relative to the adapter unit. This eliminates the need to move the adapter unit and / or disconnect it from the conductor assembly, particularly for minor positional adjustments. This can be especially useful, for example, if the conductor assembly carries mains voltage while the luminous components operate at low voltage.This approach therefore creates additional flexibility regarding the positioning of the assembly and also simplifies the positioning process. At least partially integrating the assembly into the first section of the rail profile can help to limit the complexity of the design, particularly with regard to holding the assembly in place.

[0014] Advantageous embodiments and further developments of the invention will result from the further dependent claims and from the description with reference to the figures.

[0015] In one embodiment, the assembly is designed to provide either direct or indirect lighting. This makes the lighting arrangement useful for a wide variety of applications.

[0016] In one embodiment, the lighting arrangement further comprises at least one additional assembly. This additional assembly is designed as a lighting module, or at least one lighting unit can be coupled to the additional assembly and / or at least one lighting unit can be partially accommodated by the additional assembly. The assembly and the additional assembly are configured for electrical coupling such that the additional assembly can be supplied with electrical energy provided by the adapter unit via the assembly.

[0017] In a first embodiment according to the invention, the assembly has strip-shaped contact elements on one side facing the adapter unit when the adapter unit and the assembly are inserted into the rail profile. These strip-shaped contact elements can be brought into electrically conductive contact with corresponding contact elements of the adapter unit. In particular, in one embodiment, the strip-shaped contact elements extend along the longitudinal direction of the rail profile when the assembly is inserted. In this way, the movable electrical coupling of the adapter unit and the assembly can be implemented relatively easily. Not only the coupling, but also the release of the detachable electrical coupling can be achieved quickly and easily by a technician or operator with minimal effort.

[0018] According to further training, the assembly is designed as a linear lighting module, for example, an elongated lighting module. Such lighting modules can be used to create, for example, light strips that provide functional and aesthetically pleasing lighting in both smaller and larger rooms.

[0019] In a further development process, the contact elements of the adapter unit are designed as point-like contact elements, in particular as pin-like or pin-head-like contact elements. The contact elements can thus be designed relatively compactly and with minimal material usage on the adapter unit, and arranged in a space-saving manner.

[0020] In one embodiment, the assembly comprises a double-sided printed circuit board, with the strip-shaped contact elements forming conductive traces on a main surface of the circuit board. Such contact elements can be expediently manufactured.

[0021] In particular, the double-sided printed circuit board can also be equipped with light-generating devices, such as LEDs, on its other main surface. This allows the functions of light generation and contact with the adapter unit to be combined on the circuit board. Furthermore, this saves space and assembly effort.

[0022] In one embodiment, the conductor assembly provided in the second area of ​​the rail profile is further configured to provide a control signal. The adapter unit is configured to receive the control signal from the conductor assembly and to interpret the received control signal. The adapter unit is also configured to generate an output signal from the received control signal, which is to be transmitted to the assembly for controlling the assembly and / or to controlling the assembly based on the control signal. In particular, the electrical coupling between the adapter unit and the assembly is configured for transmitting the output signal to the assembly and / or for controlling the assembly based on the control signal.

[0023] In one embodiment, the assembly is designed as a lighting module, and the lighting arrangement further comprises at least one additional assembly also designed as a lighting module. The assembly and the additional assembly are configured to transmit the output signal received from the adapter unit to the assembly for its control to the additional assembly for its control, and / or the assembly and the additional assembly can be jointly controlled according to a master-slave principle, with the additional assembly acting as a slave to the assembly acting as the master, and in particular, the additional assembly as a slave can be controlled in the same way as the assembly acting as the master. In this way, two or more lighting modules can be jointly controlled and supplied via a single adapter unit.If multiple lighting modules are to be controlled in the same way, a separate adapter unit is not required for each module. Lighting modules that are to be controlled separately can, however, each be connected to their own dedicated adapter unit. This ensures a high degree of flexibility.

[0024] In particular, the additional lighting module can also be designed as a linear lighting module.

[0025] In a second embodiment according to the invention, the adapter unit has strip-shaped contact elements on one side facing the assembly when the adapter unit and the assembly are inserted into the rail profile. These contact elements can be brought into electrically conductive contact with contact elements of the assembly. In particular, in one embodiment, the strip-shaped contact elements extend along a longitudinal direction of the rail profile when the adapter component is inserted. This also achieves a simple, slidable electrical coupling of the adapter unit with the assembly, whereby the coupling is easy to establish and preferably also easy to break.

[0026] In a further embodiment, the assembly is designed with a rail for coupling and / or at least partially accommodating the lighting units. This allows for additional flexibility by combining the rail profile with the rail of the assembly. Flexibility and design freedom can be further increased by coupling and / or accommodating one or more lighting units to or within the rail.

[0027] According to a further development, the rail of the assembly has a through-opening in the area of ​​a web of the rail facing the adapter unit when the adapter unit and the assembly are inserted into the rail profile. In this further development, the assembly also includes a connecting unit that can be inserted into the rail of the assembly. This connecting unit has a contact section that can be inserted into the through-opening to establish the electrical coupling between the assembly and the adapter unit. In this way, the electrical coupling of the adapter unit and the assembly can be achieved simply, quickly, and with minimal effort. The through-opening can, for example, be pre-fabricated in the delivered state of the rail or flexibly created on-site.

[0028] In a further development process, the outer contour of the contact section can be designed to essentially correspond to the shape of the through-opening. Thus, the through-opening can, for example, be essentially closed by the contact section after its insertion.

[0029] In one embodiment, the connecting unit is configured to feed at least the electrical energy provided by the adapter unit into a conductor assembly of the assembly's rail. In particular, the connecting unit can be mechanically locked to the assembly's rail or clipped into it. This achieves a simple, reliable, and preferably detachable electrical connection between the adapter unit and the rail's conductor assembly with minimal effort and time. The provision of electrical energy for lighting units that are coupled to or receive power from the assembly's rail is thus achieved simply and reliably.

[0030] According to a further development, the contact elements of the assembly are designed as point-like contact elements, in particular as pin-like or pin-head-like contact elements. In this way, the contact elements on the assembly can be designed relatively compactly and with minimal material usage, and arranged in a space-saving manner.

[0031] In particular, the contact elements of the assembly are arranged on the contact section of the connecting unit that can be inserted into the assembly's rail. This allows for a comparatively compact contact section.

[0032] In one embodiment, the conductor assembly provided in the second section of the rail profile is configured to provide a control signal, with the adapter unit being configured to receive the control signal from the conductor assembly and forward it to the assembly. This can be particularly advantageous if the assembly includes a rail for coupling and / or receiving one or more lighting units. In this embodiment, the control signal, preferably passed unchanged to the assembly by the adapter unit, can thus be made available to each of the lighting units coupled to and / or received by the rail, thereby enabling individual control of these lighting units.

[0033] In a further development, the assembly and the further assembly are each equipped with a rail for coupling and / or at least sectionally receiving lighting units and can be coupled to each other in such a way that the control signal forwarded to the assembly via the adapter unit can be forwarded to the further assembly.

[0034] In one embodiment, the first area is designed as a rear section of the rail profile in the operating state of the lighting arrangement. This rear section is intended to accommodate, at least partially, an assembly designed as an indirect lighting module. The rear first section and the second section are adjacent to each other and separated by a web of the rail profile, and the rail profile has a through-opening in the area of ​​the web. The adapter unit has a contact section on one side, which, when the adapter unit is inserted into the rail profile, faces the web. This contact section can be inserted into the through-opening to establish the slidable electrical coupling of the indirect lighting module to the adapter unit.By inserting and guiding the contact section into and through the opening in the bridge, the power supply to the indirect lighting module can be significantly simplified. The opening can be pre-fabricated or, if necessary, created at the desired location during the assembly of the lighting system.

[0035] In one embodiment, the lighting module(s) or lighting unit(s) is / are operable for the provision of direct or indirect lighting by means of electrical energy at a first electrical voltage. The conductor assembly in the second area is provided for the supply of electrical energy at a second electrical voltage that is higher than the first electrical voltage, and the adapter unit has a converter and is configured to receive electrical energy from the conductor assembly in the second area and to provide the electrical energy for the supply of the lighting module(s) or lighting unit(s) at the first electrical voltage.

[0036] In one embodiment, the conductor assembly in the second area of ​​the rail profile is designed to supply alternating current at a mains voltage, in particular a nominal voltage of approximately 220 to approximately 240 volts, for example 230 volts. Furthermore, in this embodiment, the adapter unit is preferably designed to supply current at a low voltage, in particular a DC voltage of less than 60 volts, for example 48 volts, for the power supply of the lighting module or the lighting unit(s) of the assembly.

[0037] According to further training, the conductor assembly provided in the second area of ​​the rail profile has at least one conductor intended to carry a control signal, and the conductor assembly further has at least two conductors, each carrying an electrical phase for the electrical supply of the lighting module or lighting unit.

[0038] In a further development phase, the adapter unit is designed to connect the assembly to at least one conductor carrying the control signal and to a selectable phase for power supply. This connection can be made with or without the interposition of an interpreter and / or processor for the control signal. The connection to the power supply can be achieved, in particular, with the interposition of a converter. The ability to select the phase to be used thus provides further flexibility in the design and operation of the lighting arrangement.

[0039] In one embodiment, at least two times three ladders, for example two times three ladders or two times five ladders, are provided in the second area of ​​the rail profile by means of the ladder device.

[0040] In an alternative embodiment, the rail profile can be designed as a low-voltage rail, with the conductor assembly in the second section configured to supply electrical current at a low voltage, in particular a DC voltage of less than 60 volts, for example 48 volts, for the lighting module of the assembly. In such a configuration, the assembly can be designed, in particular, as an indirect lighting module. With this variant, improved flexibility during assembly and installation can also be achieved by means of the sliding coupling.

[0041] According to the invention, the assembly can be mechanically coupled to the rail profile in its first region. This allows the assembly to be easily attached, independently of the adapter unit. Furthermore, the assembly can be mechanically coupled to the rail profile in its first region in such a way that, when coupled to the rail profile, it is displaceable relative to the rail profile. This allows for flexible adjustment of the assembly's position while it is held against the rail profile, which is particularly advantageous in combination with the displaceable electrical coupling to the adapter unit.

[0042] According to the invention, the assembly can be clipped into the rail profile or snapped into place with the rail profile in such a way that the assembly can be moved relative to the rail profile, in particular along the longitudinal direction of the rail profile.

[0043] In a further embodiment, the lighting arrangement can include an additional adapter unit to which a spotlight is permanently attached and electrically coupled for its power supply, or which is equipped with a coupling device by means of which a spotlight can be directly attached to the adapter unit and electrically coupled to it for its power supply. The lighting arrangement can thus be supplemented, if desired, with one or more additional spotlights or floodlights to fulfill further lighting tasks.

[0044] In particular, it may be provided that the assembly is designed to provide direct lighting, for example as a lighting module for direct lighting or for coupling a lighting unit for direct lighting, or that the assembly is designed to provide indirect lighting, for example the lighting module is designed as an indirect lighting module.

[0045] In one embodiment, the lighting arrangement can simultaneously comprise a direct lighting assembly and an indirect lighting module, each with an associated adapter unit. The lighting module or units of the direct lighting assembly and the indirect lighting module are each operable to emit light at the first electrical voltage, in particular low voltage.

[0046] In particular, the adapter unit can be freely positioned along the rail profile, whereby, if a contact section is to be inserted into the aforementioned through-hole, the through-hole is placed in a corresponding position or a suitably positioned prefabricated through-hole is selected.

[0047] 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. CONTENT OF THE DRAWING

[0049] The accompanying drawings are intended to provide a further understanding of the embodiments of the invention. 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.

[0050] 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

[0051] A first embodiment of a lighting arrangement 1 is shown. Fig. 1-9 The 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 integrated into a single track profile and combined in various ways. The lighting modules can, for example, have reflectors or lenses and / or opal diffusers. Additional lighting units can be connected to the low-voltage tracks, if present, 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 using one or more indirect lighting modules. Advantageously, not every single insertable lighting component needs to be equipped with its own converter.The track lighting system can be described in particular as a three- or five-phase system with low-voltage lighting components.

[0052] It should be mentioned that the rail profile 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.

[0053] First, the first embodiment is described, in which direct illumination is enabled by means of a linear lighting module 11.

[0054] In the first embodiment, the lighting arrangement 1 has a rail profile 3 that is open towards the visible side S, and thus, in a fully assembled position, particularly at the bottom, and has a first inner region 4 and a second inner region 5 located in the rail profile 3 above the first region 4 and thus further towards a rear side of the rail profile 3 facing away from the visible side S. At the rear, and in the fully assembled position, particularly in an upper region of the rail profile 3, 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 regions 4 and 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'.

[0055] 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. The conductor rails form a conductor assembly 6 with a total of six conductors 6a, 6b, of which four conductors 6a are designed to supply electrical energy and two opposing conductors 6b are provided for supplying control signals. Three of the conductors 6a are preferably each configured as phase conductors to supply three different electrical phases, and a fourth of the conductors 6a is configured as a neutral conductor.

[0056] The ladder assembly 6 could be in one variant, see also Fig. 16 Alternatively, for example, five poles or conductors 6a, 6b can be provided on each side of the second area 5, resulting in a total of ten conductors 6a, 6b, in order to be able to additionally switch emergency lights to a separate phase. Again, two busbars and a total of at least two conductors 6b are provided in the inner area 5 for supplying control signals.

[0057] 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.

[0058] In Fig. 1-9 Thus, conductors 6a are intended 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 (a so-called "power feeder") not shown in detail. This will be referred to below as "high voltage".

[0059] The track lighting system described here, and thus also the lighting arrangement 1, incorporates 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".

[0060] The second area 5 of the rail profile 3, designed as an upper interior space, is configured to accommodate an adapter unit 7. The adapter unit 7 includes a converter that transforms the high voltage of the conductors 6a of the conductor assembly 6 into low voltage for supplying the luminous components, in the first embodiment the lighting module 11, thereby providing the type of current required by the luminous components at the low voltage. The converter is arranged within the adapter unit 7. Preferably, the adapter unit 7 further includes a device, not shown in detail in the figures, that makes it possible to select the electrical phase to be used from among those provided by the conductors 6a and to connect the lighting unit 11 to the selected phase for power supply.

[0061] 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. 3 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. It is understood that 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.

[0062] In the area of ​​the longitudinal side surfaces of the adapter unit 7, this unit has a 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 in the variant of Fig. 11 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. 16 , 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.

[0063] It should be noted that the adapter unit 7 can be positioned freely at essentially any point along the rail 3 within the inner area 5. Furthermore, the adapter unit 7 inserted into area 5 can be moved longitudinally L along the rail profile 3 when the contact elements 13 are folded in and thus do not make contact with the conductors 6a, 6b.

[0064] 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 of the rail profile 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.

[0065] In Fig. 1-6 The second area 5 is bounded to the first area 4 by the inner longitudinal ribs 3c of the rail profile 3. These ribs 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. In the first embodiment, the flanges or side walls 3b of the rail profile 3 extend downwards beyond the ribs 3c, thus forming the first area 4.

[0066] The adapter unit 7 in Fig. 1-6 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, and one or more other contact elements 17 can serve for signal transmission for control purposes.

[0067] For lighting arrangement 1 of the Fig. 1-6 The luminous component shown is a module 2, which is designed as the linear luminaire module 11 for providing direct illumination. The luminaire module 11 can have, for example, an opal cover and / or lenses on its visible side, although other configurations, such as with or without a clear cover, with or without lenses, are also conceivable.

[0068] 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 main surface of the PCB 21, which faces outwards. These contact elements 17 serve to establish an electrical connection with the adapter unit 7 for power supply and control purposes. Light-generating devices designed as LEDs are arranged on the other, inwards-facing main surface of the PCB 21. Additional electrical and / or electronic devices for operating the LEDs, as well as conductive traces for connecting the individual devices, may also be arranged on the PCB 21.

[0069] When 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.

[0070] Fig. 3-6 The illustration shows that the adapter unit 7 has a projection 7v on a longitudinal edge adjacent to the underside of the adapter unit 7 facing area 4 in the inserted state. This projection rests against the longitudinal rib 3c when the adapter unit 7 is correctly inserted. Unlike the longitudinal rib 3c, which is flat on its side facing area 4, the other longitudinal rib 3c' has an additional end section projecting towards area 4. This end section means that, in the reverse orientation (i.e., with the projection 7v resting against the longitudinal rib 3c'), the adapter unit 7 cannot be inserted as far into area 5 as in the correct position. Fig. 3-6 This prevents electrical coupling with the conductor assembly 6 if the adapter unit 7 is inserted in an incorrect position. Furthermore, this makes it apparent to the operator if the adapter unit 7 has been inserted in an incorrect position.

[0071] The lighting module 11 is then inserted from below into the first area 4 below the adapter unit 7 and snapped or clipped into place behind further longitudinal ribs of the rail profile 3 using locking or clipping devices 16. Above the longitudinal ribs, longitudinal grooves or recesses 4a are formed on both sides in the side walls 3b in area 4, into which the locking devices 16 can engage.

[0072] The locking devices 16, together with corresponding longitudinal ribs and longitudinal grooves 4a of the profile 3, are designed such that the assembly 2 can be clipped / locked into the area 4 from below, i.e., from the visible side S, with relatively little force or pressure, and can be pulled out of the rail profile 3 from below with comparatively little force, for example, by pulling on one of the end faces of the module 11. In this embodiment, the assembly 2, in this example the lighting module 11, is not fixed in the longitudinal direction L. 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, even after being clipped into the rail profile 3, thus enabling positional adjustments.

[0073] Current is drawn by the lighting module 11 via a number of conductive traces 18 attached to the circuit board 21, each of which makes electrically conductive contact with one of the associated point contact elements 17 of the adapter unit 7. The strip-shaped contact elements 18 are located on one side of the assembly 2 facing the adapter unit 7 and extend in the longitudinal direction L of the rail profile 3 when the assembly 2 is inserted into the first, lower section 4. This allows the lighting module 11 to be moved longitudinally L within the rail profile 3 even after electrical coupling, while simultaneously ensuring a power supply as long as the circuit board 21 is positioned at any point below the contacts 17 of the adapter unit 7.

[0074] The double-sided circuit board 21 attached to the top of the light module 11 thus also separates the two rail interiors 4 and 5 and is designed to receive power from the adapter 7 attached above it.

[0075] 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 the first embodiment with the linear lighting module 11, 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, it can be provided that the control signal received by the conductor assembly 6 is 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.

[0076] An example of the light module 11 with an opal cover extending over the entire length of the light module 11 is shown in Fig. 7 und 8 As shown. Alternatively, or in addition to the opal cover, the light module 11 can be equipped with lenses 11L in variants. This is shown in Fig. 9 schematically illustrated.

[0077] The rail profile 3 can be formed from several rail profile 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 profile 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 upper high-voltage area of ​​the rail profile 3, by intermediate or connecting pieces (not shown in detail in the figures) for the electrical coupling of the corresponding conductors 6a, 6b.

[0078] For example, see Fig. 10 , in a lighting arrangement 1', which is a variant of arrangement 1, a first assembly 2 designed as a linear lighting module 11, and one or more further assemblies 12, each also designed as a linear lighting module 11a, of which in Fig. 10 Only one is shown, it is intended.

[0079] The modules 2 and 12 are each equipped at their end faces with connection devices 15, for example, connectors, such that module 2 can be electrically coupled to one of the other modules 12 at either end face. 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 as explained in more detail above. The devices 15 or "circuit board connectors" 15 for coupling adjacent lighting modules are located approximately in Fig. 7-9 not shown in detail, but for example in Fig. 1, 2 , 10 und 12 Illustrates and connects, for example, the circuit boards of the adjacent lighting modules 11, 11a.

[0080] Therefore, in a longer lighting arrangement 1', not every section of the rail profile 3 and not every lighting module 11, 11a requires a separate adapter unit in the upper (high-voltage) inner area of ​​the rail profile 5. Several assemblies 2, 12, in Fig. 10 Designed as linear light modules 11, 11a, they can be powered by a common adapter unit 7. For example, a total of three modules 11, 11a can be powered by a common adapter unit 17, whereby in particular another module 11a can be provided at each end of module 11, but a longer series with further modules 11a is also conceivable.

[0081] 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 controlled 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 not only power but also control signals corresponding to the first lighting module 11.

[0082] At the same time, the assemblies 2 and 12 can be moved together along the rail 3, for example, to make minor positional adjustments after they have been inserted into the rail profile 3. Advantageously, the adapter component 7 in the high-voltage area 5 does not need to be loosened and repositioned for this purpose.

[0083] For the lighting module 11 of the Fig. 10, 12 Does the above apply? Fig. 1-9 Described analogously. The lighting module 11a of the Fig. 10, 12 The circuit board is also designed analogously to the light module 11, whereby the printed circuit boards (PCBs) of the further assembly(s) 12, i.e., of the second and further light modules 11a indirectly coupled to the adapter component 7, are not necessarily double-sided. Rather, it may be sufficient if the circuit board of the light module(s) 11a provides power and operation for the LEDs, which, as with the light module 11, are arranged on the inward-facing main surface of the circuit board, and provides power and signal supply via the device(s) 15. Corresponding conductor tracks and devices can, for example, be arranged on the inward-facing main surface of the circuit board of the light module 11a, just like the LEDs, especially since a direct conductive connection with contact elements of an adapter unit 7 is not necessary for the light module 11a, and the contact elements 18 are therefore not required for the light module 11a.The circuit boards of the lighting module(s) 11a can therefore be manufactured more cost-effectively than those of the lighting module 11.

[0084] 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.

[0085] The track lighting system, on which the arrangements 1, 1' are based as described above, may include alternatively usable track profiles that can be used in place of track profile 3 and in Fig. 13-16 are shown as examples. The profiles of Fig. 13-15 differ from profile 3 of the Fig. 1-6 and 10 in that the flanges or side walls 3b are shortened in cross-section towards the visible side, as in Fig. 13-14 , or extended in cross-section to accommodate deeper assemblies, as in Fig. 15 , are trained. Fig. 16 shows a variant in which the upper area 5 is used to accommodate a ladder assembly 6 with a total of ten ladders, of which in Fig. 16 Only some are marked with reference symbols, and are trained.

[0086] Further variants of the lighting arrangement 1, in which the assembly 2 and the further assembly 12 are each designed as a lighting module 11', 11a', show Fig. 17-22 The lighting arrangement 1" of the Fig. 17-22 has a rail profile 3', which, as mentioned, is accordingly Fig. 15 is trained and differs from the rail profile 3 of the Fig. 1-6 , 10 with regard to the side walls or flanges 3b extended towards the visible side S, so that a deeper first area 4 is achieved.

[0087] The lighting module 11' in Fig. 17, 18 The light module 11' has a series of reflectors open towards the viewing side S, which reflect light emitted by the LEDs on the circuit board 21 in a desired manner. Except that the reflectors are provided instead of lenses and / or an opal or clear cover, and that the arrangement of the LEDs on the circuit board 21 can be suitably adapted to the arrangement of the reflectors, the light module 11' is designed analogously to the light module 11 as described above.

[0088] In Fig. 17, 18 Devices for end-face electrical coupling are not shown. Fig. 19-22 However, analogous to the embodiment of the Fig. 10, 12 , Devices 15a, 15b are provided at the facing end faces of the light modules 11', 11a' to electrically couple adjacent assemblies 2, 12 to each other, analogous to the above. Fig. 10-12 Described. Fig. 21 shows adjacent light modules 11', 11a' in an assembly step before the electrical coupling of both at their mutually facing end faces, Fig. 22 in the coupled state. The devices 15a, 15b are configured to correspond to each other, for example as plug connections. In particular, at least one further module 11a' can be provided at each of the two ends of module 11'.

[0089] The displacement of the light modules 11', 11a' relative to the adapter unit 7 in the installed state is in the same way as in the embodiments of the Fig. 1-10 Given. By allowing longitudinal movement along the rail profile 3' after the adapter unit 7 and the first lighting module 11' have been snapped or clipped into place and in the state of electrical coupling, the work steps of the Fig. 21-22 can be carried out in a simplified manner.

[0090] Operation, supply and control of the lighting modules 11', 11a' are carried out as described below. Fig. 1-12 described. In particular, in Fig. 13-22 The conductor assembly 6 in the second area 5 is configured to provide an alternating current, for example mains voltage, in the range of approximately 220V to 240V, in particular 230V at 50Hz, for the electrical supply. A converter in the adapter unit 7 transforms the high voltage into a direct current voltage of less than 60V, for example 48V, for operating the luminous components.

[0091] A lighting arrangement 1'' according to a further modification (not according to the invention) shows Fig. 44 As an example for illustration, assembly 2, which is itself configured as a lighting module 11, is electrically coupled to an adapter unit 7"' by means of a flexible cable 700. Assembly 2, wired to the adapter unit 7'" in this way, can be displaced relative to the inserted adapter unit 7"' along the longitudinal direction L of the rail profile 3, even after assembly 2 has been inserted into area 4. The length of the cable 700 and / or its positioning can be selected or varied, for example, depending on the desired possible displacement, perhaps to allow better access to a phase selection push-button switch on the underside of the adapter unit 7"' when wired. Furthermore, the lighting module 11 and the adapter unit 7"' correspond to the lighting module 11 and the adapter unit 7 described above.

[0092] Fig. 23-32 show a lighting arrangement 1a, 1a' according to a second embodiment and variants thereof.

[0093] The lighting arrangement 1a' of the Fig. 23 has a rail profile 3 that corresponds to the one described in the first embodiment.

[0094] In the second embodiment, a second, smaller rail profile 9 is accommodated in the first section 4 of the rail profile 3. The second, smaller rail 9 is supplied with low voltage by an adapter unit 7' located above it in the installed and operating state. The rail 9 is designed to accommodate, at least in sections, and / or couple with lighting units 211a, 211b, which are shown only schematically in the figures. Furthermore, the rail 9 enables the power supply of the lighting units 211a, 211b, and can also provide control signals for the lighting units 211a, 211b coupled to or accommodated by the rail 9, wherein the lighting units 211a, 211b are equipped, for example, with suitable devices for electrical and, for example, also for mechanical coupling with the rail 9.The lighting units 211a, 211b coupled to the rail 9 are preferably slidably coupled to the rail 9 and are particularly intended for direct lighting.

[0095] Furthermore, the lighting arrangement 1a' includes a connecting unit 8' which enables electrical coupling of the rail 9 and the adapter unit 7'. An assembly 2, which can be received in the first region 4 of the rail profile 3, is formed with the rail 9 and the connecting unit 8'. It is provided that the assembly 2, in particular the rail 9, can be mechanically locked to the rail profile 3 or clipped into the rail profile 3, for which suitably designed means, not shown in detail in the figures, are provided. The mechanical fastening of the assembly 2 formed with the rail 9 and the connecting unit 8' is designed analogously to the locking or clipping of the assembly 2 in the first embodiment, such that even after locking or clipping, the rail 9 and the connecting unit 8' can be moved in the longitudinal direction L of the rail profile 3.In the second embodiment as well, locking the assembly 2 to the rail profile 3 and releasing it from this locking requires relatively little force, which means that locking and releasing can be carried out easily and quickly by an operator or fitter.

[0096] The adapter unit 7' is constructed like the adapter unit 7 with regard to its basic shape and dimensions, mechanical fixation in the outer rail profile 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'.

[0097] 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. 23-32 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 profile 3, a contact device 1027 with several strip-shaped contact elements 27 is provided. When the assembly 2 is inserted into the rail profile 3 below the adapter unit 7', the contact elements 27 can each 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 region 5 of the rail profile 3, the strip-shaped contact elements 27 extend with their longitudinal direction parallel to the longitudinal direction L of the rail profile 3.

[0098] 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 profile 3, the web 9a faces the adapter unit 7'.

[0099] In the second embodiment, the multiple contact elements 28 of the assembly 2 are arranged on a projecting contact section 8a' of the connecting unit 8'. Here, the contact elements 28 are designed as point-like, pin-like, or pin-head-like contact elements 28 on the upper side of the contact section 8a'.

[0100] 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'.

[0101] The connector 8' serves as a coupling unit and subsequently ensures the power supply to the assembly 2, which is designed as a low-voltage busbar module. In the second embodiment, the busbar 9 of the assembly 2 is equipped with a conductor arrangement 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 shown in Fig. 27 shown and also in the variant of Fig. 23-24 in this form and configuration.

[0102] 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.

[0103] 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'.

[0104] The provision of electrical current at low voltage by means of 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 the first embodiment. 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 with the aid of the adapter unit 7' is also possible as in the first embodiment.

[0105] In the second embodiment, control signals provided at 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.

[0106] 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.

[0107] The connecting unit 8' is designed 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 forwarded by the adapter unit 7' via the further contact elements 27, 28 into the conductors 26b. Furthermore, the connecting unit 8' can be mechanically locked to the rail 9 of the assembly 2.

[0108] One variant of the lighting arrangement according to the second embodiment is shown in the Fig. 25-32 Except for the differences described below, the above statements regarding the Fig. 23 , 24 also on the lighting arrangement 1a of the Fig. 25-32 Application.

[0109] The lighting arrangement 1a of the Fig. 25-31 It again comprises a rail profile 3, an adapter unit 7', and a subassembly 2. With regard to the design of the rail profile 3 and the adapter unit 7' and their functions, reference is made to the above explanations.

[0110] In the variant of the, assembly group 2 comprises Fig. 25-32 in turn a 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. 27 , and a connecting unit 8 - shown enlarged in Fig. 31 - on.

[0111] The connecting unit 8 of the Fig. 25-32 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. 27-30 A first contact device 1030 with contact elements 30, see Fig. 31 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.

[0112] The connecting unit 8 also has in Fig. 25-32 The function of a coupling unit enables the electrical coupling of the rail 9 with the adapter unit 7' for the transmission of power and control signals. The connecting 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 is attached to the contact section 8a with - in Fig. 31 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'.

[0113] The contact section 8a is, in the example of the Fig. 25-31 , in contrast to the plate-like contact section 8a' in Fig. 24 , 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.

[0114] Furthermore, it should be noted that in Fig. 25-30 and 32 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 profile 3. This projection can be part of a body and / or housing of the adapter unit 7' and, in further embodiments, can be equipped with contact elements instead of the contact elements 27, whereby, however, in Fig. 25-30 , 32 Contact elements are not present on the projection 7a'. Alternatively, the projection 7a' could be omitted on the adapter unit 7'.

[0115] In the second embodiment, at least one further assembly 12 can also be provided in a variant, 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. 32 shown. Analogous to assembly 2, assembly 12 shows in Fig. 32 a rail 9, with which one or more lighting units, e.g. 211a, 211b (in Fig. 32 (not shown in detail), connectable and / or at least partially receptive to the further rail 9. The extension rail 9 of the assembly 12 in Fig. 32 also features a ladder device 26 analogous to assembly group 2 in Fig. 23-31 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.

[0116] In this way, several low-voltage track modules in the form of assemblies 2 and 12 – for example, three such assemblies, such as one assembly 12 at each end of assembly 2 – can be inserted adjacent to one another into the track profile 3 and electrically connected to each other. The assembly 12 of the Fig. 32 Unlike assembly 2, it does not have a connecting unit 8 or 8'. Therefore, it is sufficient to use only one first low-voltage busbar module, i.e., assembly 2. Fig. 32 The high-voltage busbar 3 is electrically connected via the adapter unit 7' located above it. The low-voltage busbar modules 2 and 12 – whether supplied directly or indirectly by a common adapter unit – are all connected to the same phase, which can be selected via the adapter unit 7'. Electrical current for supplying the lighting units 211a and 211b is passed on via conductors 26a at the coupling point 1202. Control signals, e.g., DALI signals, are passed on unchanged at the coupling point 1202 via the corresponding conductors 26b, thus enabling lighting units located on the extension busbar 9 of the assembly 12 to be individually controlled via their own addresses.

[0117] Out of Fig. 32 It is evident that the rail profile 3 can be formed with several end-connected rail profile sections to create a longer linear system. Suitable connecting pieces (not shown) for the sections of the rail profile 3 can be provided for this purpose. Not every section of the rail profile 3 and not every rail section 9 requires a separate adapter unit 7' in the upper (high-voltage) inner area 5 of the rail profile.

[0118] The in Fig. 23-32 The illustrated embodiment, along with its variants, also allows, after the insertion of the adapter unit 7' and the assembly 2 and, if applicable, the assembly 12 into the rail profile 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'.

[0119] Fig. 33-37 Figure 1b shows a lighting arrangement according to a third 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. 33-37 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.

[0120] The lighting arrangement 1b, 1b' of the third embodiment comprises a rail profile 3", which is analogous to the profile 3 in Fig. 1-6 , 10 , 23-32The 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 a rear side 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 profile 3" as a flat channel facing away from the second region 5. The rail profile 3" is essentially symmetrical about a longitudinal median plane, except for differing end sections of the longitudinal ribs 3c, 3c'.

[0121] The receiving area 44 serves as a first area of ​​the rail profile 3" to receive an elongated indirect lighting module 40, which can be inserted into the receiving area 44 and, in the mounted state, can emit light essentially upwards, i.e., for example towards the ceiling of the room.

[0122] The 3" rail profile in Fig. 33-37 is equipped with a three-phase, or alternatively a five-phase, conductor assembly 6 designed for mains voltage, analogous to that described above for profiles 3, 3'. The web 3a limits the inner, second 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 profile 3", opposite the visible side S, this profile has one or more through-openings 50, see Fig. 36 , equipped in the jetty 3a.

[0123] Furthermore, an adapter unit 7" is provided which can be inserted into the rail profile 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, with differences being described below.

[0124] The adapter unit 7" has a 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. 32 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.

[0125] 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. 33 , 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.

[0126] The adapter unit 7" is, like the adapter unit 7, 7', with corresponding selection or insertion of the opening 50, basically freely positionable along the rail profile 3" but after passing the contact section 7a" through the opening 50, no longer longitudinally displaceable.

[0127] The first indirect lighting module 40, which can be slidably inserted in the rail profile 3", has a double-sided printed circuit board 41 ("PCB"). On its underside, the PCB 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, with the indirect lighting module 40 being considered the "master". The connection can be made at a joint 4040 by means of connection devices not shown in detail. Fig. 37 . 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.

[0128] The indirect lighting module 40a is supplied with electricity via the indirect lighting module 40, whereby, as in the first embodiment, 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 to be used for the power supply of the indirect lighting modules 40, 40a can also be selected by means of the adapter unit 7".

[0129] The indirect lighting modules 40, 40a are controlled in an analogous manner to the direct lighting modules 11, 11a or 11', 11a', wherein the indirect lighting modules 40, 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 the 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.At interface 4040, the output signal resulting from the interpretation is passed in both cases. The output signal can be implemented, for example, using pulse-width modulation or pulse-pause modulation.

[0130] The power supply and control of the indirect lighting module 40 can be achieved quickly and easily. A relatively small through-opening 50 is created in the web 3a in the area of ​​the top of the rail profile 3". The opening 50 can either be prefabricated or flexibly created on site. The freely positionable adapter 7", which is initially movable with its contact elements 13 folded in, is then positioned in the rail profile 3" below the opening 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.

[0131] The adapter unit 7" is thus configured as "slaves" for supplying the indirect module 40 and, if necessary, further indirect modules 40a in the intake area 44. In addition to the adapter unit 7", in Fig. 33-37 another, in Fig. 34 , 36, 37 The non-visible adapter unit 7 is received in the second area 5 of the rail profile 3" and configured as described in the first embodiment. Using the further adapter unit 7, one or more linear lighting modules 11, 11a can be connected as assemblies 2, 12 analogously. Fig. 1-10 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".

[0132] In Fig. 33, 35 The front face of the rail profile 3" can be seen with two adapter units 7, 7" inserted 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.

[0133] As in the first and second embodiments, in the third embodiment, the area 4, which is provided for the at least partial and preferably substantially complete reception of the assembly(s) 2, 12 preferably designed for direct illumination, is designed as a front area 4 of the rail profile 3" in the operating state of the lighting arrangement 1b, 1b'. The front of the lighting arrangement 1b or 1b' corresponds to its visible side S, in particular its underside in a mounted state.

[0134] 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 profile 3". The receiving area 44, referred to here as the first area, and the second area 5 are thus arranged on different sides of the web 3a, with the second area 5 being provided between the web 3a and the area 4. In the third embodiment, the rear first area 44 and the second area 5 are therefore adjacent to each other and are separated from each other by the web 3a.

[0135] It should be mentioned that the contact devices 1017a, 1047 described above for the third embodiment enable a simple and quick, movable electrical coupling which advantageously requires little effort and time during assembly and is also space-saving.

[0136] In one variant (not according to the invention), which is mentioned here as an example for illustration, the contact devices 1017a, 1047 can be connected by a cable connection analogous to the one described above. Fig. 44 The described components shall be replaced, with sufficient cable length being provided to allow the indirect lighting module 40 and, if applicable, the extension indirect lighting module 40a to be moved relative to the adapter unit used.

[0137] The exemplary embodiments described above show 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.

[0138] In particular, the indirect lighting module(s) 140, 140a can be made of Fig. 33-37 with reference to Fig. 1-32 The described direct lighting modules 11, 11a, 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'.

[0139] As described above, for extension rails 9, see Fig. 32 , or extension modules 11a, 11a', 40a, see Fig. 10 , 19 and 37 , no separate adapter unit is necessary.

[0140] However, a dedicated adapter unit is preferably provided for each of the differently configured assemblies 2, 12. For the lighting modules 11, 11a, 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 dedicated adapter unit 7, 7', 7" for each. In particular, with regard to the basic shape and dimensions, as well as the mounting in the second area 5 and the contact with the conductor assembly 6, the adapter units 7, 7', 7" are essentially analogous.

[0141] 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 or 11', 11a' in the rail profile, for example, next to the first adapter unit 7" for other purposes. Similarly, to combine the indirect lighting modules 40, 40a with a module 2 with the low-voltage rail 9, a second adapter unit 7' can be used in addition to the adapter unit 7" in a second manner. This allows for flexible combination of different direct or indirect lighting components while simultaneously limiting the complexity of the adapter units 7, 7', 7" in terms of electrical and control engineering.

[0142] Furthermore, the rail system can provide an adapter unit, not shown in detail in the figures, for spotlights or "spotlights" also not shown in detail, wherein such an adapter unit, for example, with the exception of the absence of the contact elements 17, is essentially as in Fig. 1-22 The spotlight is designed and additionally equipped on its underside facing the visible side S with a coupling device for mechanical and electrical coupling of the spotlight to the adapter unit. The spotlight is not designed to be movable relative to the adapter unit. For such spotlights, mechanical fastening in the rail profile 3, 3' or 3" is achieved via the connecting element to the adapter unit, and the latter is mechanically fixed in the second area 5.

[0143] Alternatively, it is conceivable, for example, to provide contact elements 17a for supplying an indirect lighting module and contact elements 17 for supplying modules 11, 11a, 11', and 11a' simultaneously on an adapter unit, such as adapter unit 7". Similarly, it would be conceivable to provide contact elements 17a for an indirect module 40 on adapter unit 7'. In such a modification, only one adapter unit is required instead of two, although it is more complex in terms of electrical and control technology, especially if direct and indirect lighting are to be controlled independently of each other.

[0144] 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.

[0145] For example, in some variants of the embodiment, three pin contacts 17 or 17a can serve to create the possibility of a so-called "tunable white," with the pin contacts 17, 17a providing positive and negative current contacts for this purpose. In this case, the contact elements 17, 17a can have the following configuration: first contact element positive (cold); second contact element positive (warm); third contact element negative.

[0146] 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.

[0147] The above describes a track lighting system that allows for the combinable mounting of movable spotlights, lighting modules and low-voltage tracks, which can themselves accommodate further lighting units, especially in a movable manner, in a three-phase or five-phase track.

[0148] A lighting arrangement 100 according to a fourth embodiment, and a variant 100' thereof, show Fig. 38-43 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.

[0149] 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. 38 are shown schematically and can be of different types, for example they can be designed as linear modules 111b or spots 111a.

[0150] The rail profile 109 has a first section 144 and a second section 125, see the cross-sectional view of the Fig. 42 . In the inner, in Fig. 42 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 profile 109. Fig. 42, 43 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.

[0151] 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.

[0152] 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.

[0153] The in Fig. 39 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.

[0154] 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.

[0155] 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.

[0156] 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.

[0157] 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.

[0158] The receiving area 144 serves to receive a component assembly 2 designed as an elongated indirect lighting module 140, which - in Fig. 42, 43 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.

[0159] To supply the indirect lighting module 140 with electrical current and preferably with control signals, the 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. 38 . When the coupling unit 108 is inserted into the rail 109, the contact section 109 is inserted into the through-opening 110 in such a way 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.

[0160] 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.

[0161] 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. 39 .

[0162] When 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.

[0163] In the described design with the interacting contact devices 1128 and 1147, complex wiring of the indirect lighting module 140 is therefore 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...), can then be installed. Fig. 41 , can be inserted quickly, variably and flexibly without much effort.

[0164] 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.

[0165] Fig. 41 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. 41 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.

[0166] 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.

[0167] The preferably double-sided printed circuit board 141 ("PCB") of the first indirect lighting module 140 enables, in the exemplary embodiment of the Fig. 38-43 Not only does it supply power to module 140, but it also interprets control signals that are transmitted via contact devices 1130, 1128, and 1147 from the conductor assembly 126 through unit 108 to the first module 140, thus enabling control, for example, dimming. Module 140a ("slave") is also controlled via its end-face coupling, just like module 140. The evaluation of the control signal transmitted by conductors 126b is carried out by devices of the first indirect lighting module 140 ("master"), whereby an output signal is generated based on the control signal. This output signal is used by module 140 to control itself and is also passed on at the connection point 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.

[0168] 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.

[0169] The rail profiles 3, 3', 3", and those of the Fig. 13, 14, 16 , and rails 9, 109, can each be extruded from a metal material, in particular an aluminum material, for example.

[0170] Sliding point contact elements on strip- or web-shaped contact elements, as described above, enable particularly easy and quick assembly.

[0171] Although the invention has been fully described above with reference to preferred embodiments, it is not limited to these, but can be modified in many different ways. Reference symbol list
