Description

FIELD OF THE INVENTION

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 of these.

TECHNICAL BACKGROUND

Lighting arrangements based on rail systems, for example for lighting purposes in buildings, are already known. For example, systems have already been proposed in which electrical conductors for providing a supply voltage and control signals are integrated into a rail profile. Such rail systems include, for example, a number of light inserts of different types, for example spots or linear light inserts, which can also be combined.

Furthermore, for example in the EP 3 336 420 B1 describes a lighting system that includes a channel for receiving a lighting unit that can be inserted into it. A connector insertable into the channel is configured to electrically couple bus bar sections together. When inserted into the channel, the lighting unit and the connector can be arranged in an overlapping manner within the channel.

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

Furthermore, for example in the EP 3 217 090 B1 describes an adapter intended to carry a lighting device and electrically connect it to an electrified rail.

In addition, the EP 3 719 394 A1 a lighting device with a lamp and an adapter. The adapter is used to connect the light to a rail as a carrier. A connecting section of the adapter has a sliding element which can be slidably connected to the rail serving as a carrier. The lamp in turn has a guide rail with first electrical contacts, while the adapter has a carriage with second electrical contacts, which is slidably connected to the guide rail. An intermediate section is provided between the carriage and the connecting section and defines a pivot joint between the carriage and the connecting section.

Although conventional rail systems of this type already offer an advantageous, high degree of flexibility in the design of a lighting solution adapted to individual circumstances, it has been shown that an improvement in flexibility in the design and construction of such lighting arrangements would be desirable with a relatively simple and cost-effective construction.

SUMMARY OF THE INVENTION

Against this background, the invention is based on the object of proposing a lighting arrangement that offers improved flexibility and at the same time is constructed in a comparatively simple and economical manner.

According to the invention, this object is achieved by a lighting arrangement having the features of patent claim 1 .

• einer Baugruppe, welche als ein Leuchtmodul ausgebildet ist oder mit welcher mindestens eine Leuchteinheit koppelbar und/oder durch welche mindestens eine Leuchteinheit mindestens abschnittsweise aufnehmbar ist;
• einem Schienenprofil mit einem ersten Bereich zur mindestens abschnittsweisen Aufnahme der Baugruppe und mit einem zweiten Bereich, in dem entlang des Schienenprofils eine Leitereinrichtung zur Bereitstellung mindestens von elektrischer Energie vorgesehen ist; und
• einer Adaptereinheit, die in dem zweiten Bereich des Schienenprofils mindestens abschnittsweise aufnehmbar ist und dafür eingerichtet ist, mit der Leitereinrichtung in dem zweiten Bereich elektrisch gekoppelt zu werden, elektrische Energie von der Leitereinrichtung aufzunehmen und der Baugruppe elektrische Energie für die Versorgung des Leuchtmoduls oder der Leuchteinheit bereitzustellen.

A lighting arrangement is proposed with:

• an assembly which is 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 accommodated at least in sections;
• a rail profile with a first area for at least partially accommodating the assembly 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 accommodated at least in sections in the second area of the rail profile and is set up to be electrically coupled to the conductor device in the second area, to receive electrical energy from the conductor device and the assembly to supply electrical energy to the lighting module or the lighting unit to provide.

The adapter unit and the subassembly are set up for electrical coupling to one another in such a way that the subassembly can be displaced along a longitudinal direction of the rail profile relative to the adapter unit inserted in the second region of the rail profile.

One of the ideas on which the invention is based is to further increase the flexibility and versatility in the construction of the lighting arrangement, on the one hand by allowing the adapter unit to be accommodated at a selectable position along the rail profile and on the other hand the assembly that provides the luminous components or is provided for their coupling or recording, can also be varied in their position along the profile rail relative to the adapter unit. It is therefore possible to avoid displacing the adapter unit and/or detaching the coupling of the adapter unit from the ladder device, in particular for smaller position adjustments. This can be additionally useful, for example, if the conductor device carries an electrical mains voltage, for example, while the luminous components are operated at low voltage, for example. According to one aspect, additional scope is therefore created with regard to the positioning of the assembly and the positioning is also made easier. Accommodating the assembly at least in sections in the first area of the rail profile can contribute to limiting the complexity of the construction, in particular with regard to holding the assembly.

Advantageous refinements and developments of the invention result from the further dependent claims and from the description with reference to the figures.

In one configuration, the assembly is provided for providing direct lighting or for providing indirect lighting. In this way, the lighting arrangement can be useful for many applications.

In one configuration, the lighting arrangement also has at least one further assembly. The 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 accommodated at least in sections by the additional assembly. In this case, the assembly and the further assembly are set up for an electrical coupling with one another in such a way that the further assembly can be supplied at least with electrical energy provided by the adapter unit via the assembly.

According to a development, the assembly is designed as a linear lighting module, for example an elongated lighting module. Such lighting modules can be used, for example, to form light bands that enable functional and aesthetic lighting in smaller and larger rooms.

In one embodiment, the subassembly has strip-shaped contact elements on a side thereof that faces the adapter unit when the adapter unit and the subassembly are inserted into the rail profile. In this case, the strip-shaped contact elements can be brought into electrically conductive contact with associated contact elements of the adapter unit. In particular, the strip-shaped contact elements extend with their longitudinal direction in the inserted state of the assembly along the longitudinal direction of the rail profile. In this way, the displaceable electrical coupling of the adapter unit and assembly can be implemented in a relatively simple manner. Not only the coupling, but also the cancellation of the detachable electrical coupling can be achieved quickly and easily by a fitter or operator with little effort.

In a development, the contact elements of the adapter unit are designed as point contact elements, in particular as pin-like or pin-head-like contact elements. The contact elements can thus be designed to be relatively compact and material-saving on the adapter unit and arranged in a space-saving manner.

In one embodiment, the assembly has a double-sided printed circuit board, with the strip-shaped contact elements being designed as conductor tracks on a main surface of the printed circuit board. Such contact elements can be manufactured expediently.

In particular, the double-sided printed circuit board can also be provided with light-generating devices, for example LEDs, on its other main surface. In particular, the functions of generating light and making contact with the adapter unit can thus be combined on the printed circuit board. In addition, space and assembly costs can be saved in this way.

In a further refinement, the assembly is designed with a rail for coupling and/or receiving the lighting units at least in sections. This allows additional flexibility by combining the rail profile with the rail of the assembly. Flexibility and freedom of design can be further increased by coupling and/or accommodating one or more lighting unit(s) on or in the rail.

According to a development, the rail of the assembly has a through-opening in the area of a web of the rail, which faces the adapter unit when the adapter unit and the assembly are inserted into the rail profile. In this development, the assembly also includes a connection unit which can be inserted into the rail of the assembly, the connection unit having a contacting section and the contacting section being insertable into the through-opening in order to bring about the electrical coupling of the assembly to the adapter unit. In this way, the electrical coupling of the adapter unit and assembly can be achieved in a simple manner, quickly and with little effort. The passage opening can, for example, already be prefabricated when the rail is delivered or can be flexibly introduced on site.

In one development, an outer contour of the contacting section can be designed to essentially correspond to a shape of the through-opening. The through-opening can thus be essentially closed, for example, by the contacting section after it has been inserted.

In one configuration, the connection unit is set up to feed at least electrical energy provided by the adapter unit into a conductor device of the rail of the assembly. In particular, the connection unit can be latched mechanically to the rail of the assembly or can be clipped into the rail of the assembly. The electrical coupling of the adapter unit and the conductor device of the rail is thus achieved in a simple, reliable and preferably detachable manner and with little effort and little time. The provision of electrical power to lighting units coupled to or received from the rail of the assembly is accomplished in a simple, reliable manner.

According to a development, the adapter unit has strip-shaped contact elements on a side that faces the assembly when the adapter unit and the assembly are inserted into the rail profile, which can be brought into electrically conductive contact with contact elements of the assembly. In particular, the strip-shaped contact elements extend with their longitudinal direction in the inserted state of the adapter component along a longitudinal direction of the rail profile. With this development, too, a displaceable electrical coupling of the adapter unit to the assembly is achieved in a simple manner, with the coupling being easy to establish and preferably also easy to cancel.

According to a development, the contact elements of the assembly are designed as point 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 to be relatively compact and material-saving and arranged in a space-saving manner.

In particular, the contact elements of the assembly are arranged on the contacting section of the connecting unit that can be inserted into the rail of the assembly. A comparatively compact contacting section is thus possible.

In one embodiment, the conductor device provided in the second region of the rail profile is also set up to provide a control signal, the adapter unit being set up to receive the control signal from the conductor device and to interpret the received control signal, and the adapter unit being set up to start from from the received control signal to form an output signal to be transmitted to the assembly for controlling the assembly and/or to control the assembly based on the control signal. In particular, the electrical coupling of the adapter unit and the assembly is set up for the transmission of the output signal to be transmitted to the assembly and/or for the control of the assembly based on the control signal.

In one configuration it is provided that the assembly is designed as a lighting module and that the lighting arrangement also has at least one further assembly designed as a lighting module. It is provided here that the assembly and the further assembly are set up to transmit the output signal transmitted from the adapter unit to the assembly for its control to the further assembly for its control and/or that the assembly and the further assembly together according to a Master-slave principle are controllable, the module as a master is subordinate to the further module as a slave, and in particular the further module can be controlled as a slave in the same way as the module as a master. In this way, two or more lighting modules can be controlled and supplied together via an adapter unit. If several lighting modules are to be controlled in the same way, a separate adapter unit does not have to be provided for each of the lighting modules. Lighting modules that are to be controlled separately can nevertheless each be coupled with a specially assigned adapter unit. A high degree of flexibility is thus achieved.

In particular, the further light-emitting module can also be designed as a linear light-emitting module.

In one embodiment, the conductor device provided in the second area of the rail profile is set up to provide a control signal, with the adapter unit being set up to pick up the control signal from the conductor device 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. The control signal forwarded to the assembly by the adapter unit in this embodiment, preferably unchanged, can thus be made available to each of the lighting units coupled to the rail and/or accommodated by it, which enables single, individual control of these lighting units.

In a further development, the subassembly and the further subassembly are each designed with a rail for coupling and/or receiving lighting units at least in sections and can be coupled to one another in such a way that the control signal forwarded to the subassembly via the adapter unit can be forwarded to the further subassembly.

In one embodiment, the first area is designed as a first area of the rail profile on the rear when the lighting arrangement is in use. In this case, the rear first area is provided for at least partially accommodating an assembly designed as an indirect lighting module, the rear first area and the second area are formed adjacent to one another and are delimited from one another by a web of the rail profile, and the rail profile has a through-opening in the area of the web . On a side that faces the web when the adapter unit is inserted into the rail profile, the adapter unit has a contacting section that can be inserted into the through-opening to bring about the displaceable electrical coupling of the indirect light module to the adapter unit. A significantly simplified supply of the indirect light module can be achieved by guiding the contact section in and through the passage opening of the web. The through-opening can be prefabricated or can be introduced at the desired location as required when constructing the lighting arrangement.

In one configuration, the lighting module(s) or the lighting unit(s) can be operated at a first electrical voltage to provide direct or indirect lighting by means of electrical energy. The conductor device in the second area is intended to provide the electrical energy at a second electrical voltage that is higher than the first electrical voltage, and the adapter unit has a converter and is set up to transfer electrical energy from the conductor device in the second Record area and provide the electrical energy for the supply of the / the lighting module (s) or the lighting unit (s) at the first electrical voltage.

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

According to a further development, the conductor device provided in the second area of the rail profile has at least one conductor, which is intended to carry a control signal, and the conductor device also has at least two conductors, each of which represents an electrical phase for the electrical supply of the lighting module or of the lighting unit.

In a further development, the adapter unit is set up to couple the assembly to the at least one conductor carrying the control signal and to one of the phases for the power supply. The coupling can take place with or without the interposition of an interpretation and/or processing of the control signal. The coupling to the power supply can take place in particular with the interposition of a converter. Further flexibility in the construction and operation of the lighting arrangement is thus created by the possibility of selecting the phase to be used.

In one embodiment, at least two times three conductors, for example two times three conductors or two times five conductors, are provided in the second region of the rail profile by means of the conductor device.

In an alternative embodiment, the rail profile can be embodied as a low-voltage rail, with the conductor device in the second area being embodied for the purpose of supplying electricity at a low voltage, in particular a direct voltage of less than 60 volts, for example 48 volts, for the supply of the lighting module of the assembly to provide. In such a configuration, the assembly can be designed in particular as an indirect light module. In this variant, an improvement in flexibility during construction and assembly can also be achieved with the aid of the displaceable coupling.

In one configuration, the adapter unit and the assembly are set up for electrical coupling to one another by means of cabling. In this case, the wiring can be formed in particular with a flexible cable. Such an electrical coupling by means of cabling can enable the assembly to be moved relative to the adapter unit and at the same time be implemented in a cost-effective manner.

In one embodiment, the assembly can be mechanically coupled to the rail profile in its first area. In this way, the assembly can be attached in a simple manner and independently of the adapter unit. In particular, the subassembly can be mechanically coupled to the rail profile in the first region in such a way that the subassembly can be displaced relative to the rail profile when coupled to the rail profile. A flexible correction of the position of the assembly when it is held on the rail profile is therefore possible and particularly advantageous in combination with the displaceable electrical coupling to the adapter unit.

For example, the subassembly can be clipped into the rail profile or latched to the rail profile in such a way that the subassembly can be displaced relative to the rail profile, in particular along the longitudinal direction of the rail profile.

In a further configuration, the lighting arrangement can have a further adapter unit, to which a spotlight is permanently connected and electrically coupled for the supply of the spotlight, or which is designed with a coupling device, by means of which a spotlight can be attached directly to the adapter unit and connected to the adapter unit for the Supply of the spotlight can be electrically coupled. If desired, the lighting arrangement can thus be supplemented by one or more spotlights or radiators in order to be able to fulfill further lighting tasks.

In particular, it can 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.

In one configuration, the lighting arrangement can also have an assembly for direct lighting and an indirect lighting module, each with an associated adapter unit. The lighting module or the lighting unit(s) of the assembly provided for direct lighting and the indirect lighting module can each be operated at the first electrical voltage, in particular low voltage, for the emission of light.

In particular, the adapter unit can be freely placed along the rail profile, with the through-opening being introduced in the corresponding position or a suitably positioned prefabricated through-opening being selected if a contacting section is to be inserted into the said through-opening.

The above configurations and developments can be combined with one another as desired, insofar as this makes sense. Further possible configurations, developments and implementations of the invention also include combinations of those described above or below with regard to the exemplary embodiments that are not explicitly mentioned Features of the invention. 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.

Furthermore, it should be pointed out that the configurations and developments described above in connection with can equally apply to the invention.

Other embodiments and many of the foregoing advantages will become apparent by reference to the drawings. The elements of the drawings are not necessarily shown to scale with respect to one another.

DESCRIPTION OF EXEMPLARY EMBODIMENTS

A first exemplary embodiment of a lighting arrangement 1 is shown Figures 1-9 . The lighting arrangement 1 is here formed with components that are part of a modular track lighting system. The rail lighting system is designed in such a way that linear lighting modules and/or low-voltage rails and/or spotlights can be accommodated in a rail profile and combined in many ways. The light modules can have reflectors, for example, or can have lenses and/or opal covers. If available, additional lighting units can be coupled to the low-voltage rails, which, like the linear lighting modules and spotlights, are preferably used for direct lighting. In addition, the track lighting system includes the option of in some variants to provide indirect lighting by means of one or more indirect lighting modules. Advantageously, not every single, insertable luminous component has to be equipped with its own converter. The track lighting system can in particular be referred to as a three- or five-phase system with low-voltage lighting components.

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

The first exemplary embodiment is described first, in which direct lighting is made possible by means of a linear lighting module 11 .

In the first exemplary embodiment, the lighting arrangement 1 has a rail profile 3, which is open towards the visible side S, and thus in a fully assembled position in particular on the lower side, and a first inner area 4 and one in the rail profile 3 above the first area 4 second inner region 5 lying 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 in particular in an upper area of the rail profile 3, the second area 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 delimit the regions 4 and 5 from one another, with an intermediate space between the longitudinal ribs 3c, 3c' providing access to the second region 5 from the first region 4. Except for the end sections of the longitudinal ribs 3c, 3c', the rail profile 3 is symmetrical in cross section with respect to a longitudinal center plane of the profile 3.

In the second region 5 busbars are arranged on both sides along the rail profile 3 and parallel to its longitudinal direction L, each with three poles or conductors. The conductor rails form a conductor device 6 with a total of six conductors 6a, 6b, of which four conductors 6a are designed to provide electrical energy and two conductors 6b arranged opposite one another are designed to provide electrical energy provided by control signals. Three of the conductors 6a are preferably in the form of phase conductors for providing three different electrical phases, and a fourth of the conductors 6a is in the form of a neutral conductor.

The conductor device 6 could in a variant, see also 16 , Alternatively, for example, provide five poles or conductors 6a, 6b on both sides of the second area 5 and thus a total of ten conductors 6a, 6b in order to be able to switch additional emergency lights in a separate phase. Again, two busbars and a total of at least two conductors 6b for providing control signals are provided in the inner region 5 .

For example, a DALI signal for control is provided by means of the conductor 6b. However, a control signal based on other control or dimming methods is also conceivable.

In Figures 1-9 the conductors 6a are therefore provided for supplying luminous components with electrical energy and are supplied with electrical current, preferably alternating current at mains voltage, around 220-240V, for example 230V, and a mains frequency by a feed unit (a so-called "power feeder"), which is not shown in detail of for example 50 Hz. In the following, this will be referred to as "high voltage".

In the track lighting system described here and thus also in the lighting arrangement 1 , luminous components are provided which are operated with electrical energy at a significantly lower voltage, for example at a direct voltage of less than 60V, for example 48V. This will be referred to below as "low voltage".

The second area 5 of the rail profile 3 designed as an upper interior space is designed to accommodate an adapter unit 7, with the adapter unit 7 having a converter that converts the high voltage of the conductor 6a of the conductor device 6 into low voltage for supplying the luminous components, in the first exemplary embodiment of the luminous module 11, converts and thereby those of the luminous Components required type of current at the low voltage provides. The converter is arranged inside the adapter unit 7 . The adapter unit 7 preferably also has a device, not shown in detail in the figures, which makes it possible to select the electrical phases provided by the conductors 6a to be used and to couple the lighting unit 11 to the selected phase for the power supply.

In the installed state, the adapter unit 7 is for the most part accommodated within the second area 5 and essentially has the basic shape of an elongated cuboid with beveled longitudinal edges on the side of the web 3a that faces the web 3a in the installed state. Here, the adapter unit 7 is slim and space-saving. For example, see 3 , a height H7 of the adapter unit 7 is about H7=28 mm and a width B7 of the adapter unit 7 is about B7=14 mm. In particular, the ratio H7/B7 is therefore approximately 2. A length of the adapter unit 7, see 1 , can be about L7 = 300 mm. It goes without saying that deviations from these values for H7, B7 and/or L7 are possible in variants, for example H7, B7 and/or L7 could each deviate by 2 mm up or down from the stated values.

In the area of the longitudinal side faces of the adapter unit 7, the latter has a contact device 1013 with contact elements 13, which can be moved or folded out of the outer surface of the adapter unit 7 in order to contact one of the conductors 6a in an electrically conductive manner. Contact elements 13 can also be provided for picking up the control signal, for example as for the variant in FIG 11 outlined as two central contact elements 13 of a movable arrangement of six contact elements 13, three of which can protrude from one of the two longitudinal sides of the adapter unit 7 of this. In this way, the adapter unit 7 can be electrically coupled to the conductor device 6 in order to receive electrical energy and control signals from the conductor device 6 . The contact elements 13 can be folded out or folded in by a mechanism that can be actuated by a fitter or operator. Especially in the case of a ten-pole rail, such as in 16 , the contact device 1013 is not necessarily provided with contact elements 13 for contacting each of the ten conductors 6a, 6b, but can also be equipped with, for example, four or six contact elements 13.

It should be pointed out that the adapter unit 7 can be placed anywhere along the rail 3 in the inner region 5 essentially at any point. In addition, the adapter unit 7 used in the area 5 can be displaced in the longitudinal direction L of the rail profile 3 when the contact elements 13 are folded in and thus do not contact the conductors 6a, 6b.

Furthermore, mechanical engagement elements 14 are provided in the area of the two longitudinal side surfaces of the adapter unit 7, which can also be moved or folded out of the outer surface in order to mechanically secure the adapter unit 7 in a detachable manner by reaching behind the inner longitudinal ribs 3c of the rail profile 3. In addition, for example, catch-like or clip-like further engagement elements can be provided, which enable a temporary, detachable fixation to facilitate assembly.

In Figures 1-6 the second area 5 is delimited towards the first area 4 by the inner longitudinal ribs 3c of the rail profile 3 . These ribs 3c form a kind of two-part intermediate wall, in the central area of which an intermediate space 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 reach down beyond the ribs 3c, whereby the first region 4 is formed.

The adapter unit 7 in Figures 1-6 has on the side facing the visible side S in the installed state, in the figures the underside, punctual, pin-like or pin-head-like contact elements 17, some of which serve as "current collectors" for producing the electrical supply of the lighting module 11, and one or more other Contact elements 17 can be used for signal transmission for control purposes.

For the lighting arrangement 1 of Figures 1-6 an assembly 2 is shown as the luminous component, which is designed as the linear luminous module 11 for providing direct illumination. The light module 11 can be seen on the Example have an opal cover and / or lenses, other configurations, for example with a clear cover or without a cover, with or without lenses, are also conceivable.

The lighting module 11 also has, on the upper side thereof when installed, a double-sided printed circuit board ("PCB") 21, on the main surface of which, which faces outwards on the lighting module 11, strip-shaped contact elements 18 are formed as conductor tracks and for establishing an electrical coupling with the adapter unit 7 via the contact elements 17 are used for the purpose of power supply and for control purposes. Light generating devices designed as LEDs are arranged on the other, inwardly facing main surface of the printed circuit board 21 . Further electrical and/or electronic devices for the operation of the LEDs, as well as conductor tracks for connecting the individual devices, can also be arranged on the circuit board 21 .

When assembling the lighting arrangement 1, the adapter unit 7 is first inserted from below into the second region 5, electrically coupled to the conductor device 6 by means of the contact elements 13, for example by rotating an actuating element, and additionally secured mechanically by means of the elements 14, for example.

Figures 3-6 show that the adapter unit 7 has a projection 7v on a longitudinal edge adjacent to the underside of the adapter unit 7 facing the area 4 in the inserted state, which protrudes against the longitudinal rib 3c when the adapter unit 7 is correctly inserted. The other longitudinal rib 3c' has, in contrast to the longitudinal rib 3c which is flat on a side facing the region 4, an additional end section which projects towards the region 4. The effect of this end section is that the adapter unit 7 can be inserted less far into the region 5 in the reverse orientation, ie with the projection 7v on the longitudinal rib 3c' than in the correct position Figures 3-6 . Electrical coupling with the conductor device 6 can thus be avoided when the adapter unit 7 is in an incorrect position of use. In this way, insertion of the adapter unit 7 in an incorrect position can also be recognized by the operator.

The light module 11 is then inserted from below into the first region 4 below the adapter unit 7 and snapped or clipped in behind further longitudinal ribs of the rail profile 3 with the aid of snap-in or clip-in devices 16 . Above the longitudinal ribs, longitudinal grooves or recesses 4a are formed in the side walls 3b on both sides in the area 4, in which the latching devices 16 can engage.

The latching devices 16 along with corresponding longitudinal ribs and longitudinal grooves 4a of the profile 3 are designed in such a way that the assembly 2 can be clipped/latched into the area 4 with only relatively little force or pressure from below, i.e. from the visible side S, and also with comparatively little Force can be pulled out of the rail profile 3 again from below, for example by tightening on one of the front ends of the module 11. Here, in particular, a fixation of the assembly 2, in this example the lighting module 11, in the longitudinal direction L is not provided in the exemplary embodiment. This and the suitable force effect of the latching/clipping devices 16 enable the lighting module 11 to be longitudinally displaceable in the longitudinal direction L, even after it has been clipped into the rail profile 3, with which position adjustments are possible.

The power consumption by the light module 11 is made possible by means of a number of conductor tracks 18 attached to the printed circuit board 21, which each come into electrically conductive contact with an assigned one of the punctiform contact elements 17 of the adapter unit 7. Here, the strip-shaped contact elements 18 are provided on a side of the assembly 2 that faces 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 region 4 . In this way it is achieved that the lighting module 11 can still be moved within the rail profile 3 in the longitudinal direction L even after the electrical coupling and at the same time a power supply is ensured as long as the circuit board 21 is located at any point under the consumers 17 of the adapter unit 7 .

The double-sided circuit board 21 attached to the top of the lighting module 11 thus also separates the two rail interiors 4 and 5 and is set up to receive power from the adapter 7 attached above.

The control signal, for example a DALI signal or a control signal based on another protocol, is taken from the conductor device 6 by the adapter unit 7 and the lighting module 11 is operated on the basis of this control signal. In the first exemplary embodiment with the linear light-emitting module 11, the control signal can be interpreted by devices in the adapter unit 7, an output signal for controlling the light-emitting module 11 can be generated and the output signal can be transmitted to the light-emitting module 11 via one or more of the contact elements 17. Alternatively, it can be provided that the control signal picked up by the conductor device 6 is forwarded by the adapter unit 7 via one or more of the contact elements 17 to the lighting module 11 and is interpreted by devices in the lighting module 11 .

An example of the light-emitting module 11 with an opal cover, which extends over the entire length of the light-emitting module 11, in FIG Figures 7 and 8 shown. Alternatively, or in addition to the opal cover, the lighting module 11 can be equipped with lenses 11L in variants. this is in 9 schematically illustrated.

The rail profile 3 can be formed with several rail profile sections, which are connected to one another to form a longer linear or angled system of selectable length, which can accommodate a large number of luminous components of the same or different types. If the rail profile 3 is constructed with several sections joined together, each with busbar pieces arranged therein to form the conductor device 6, the busbar pieces forming the conductor device 6 can be connected in the second area 5, i.e. in the upper high-voltage area of the rail profile 3, with intermediate or connecting pieces (in the figures not shown in detail) for the electrical coupling of the corresponding conductors 6a, 6b are electrically connected.

For example, see 10 , in a lighting arrangement 1', which is a variant of the arrangement 1, a first subassembly 2 designed as a linear lighting module 11 and one or more further subassemblies 12, each also designed as a linear lighting module 11a, of which in 10 only one is shown may be provided.

The assemblies 2, 12 are each equipped at the front with connection devices 15 provided for this purpose, for example plug connectors, such that the assembly 2 can be electrically coupled to one of the other assemblies 12 at both ends of the assembly. In this way, the subassembly 2 and, via this, also the subassembly(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 "board connectors" 15 for coupling adjacent light modules are approximately Figures 7-9 not shown in detail, but for example in Figures 1, 2 , 10 and 12 illustrated and connect, for example, the circuit boards of the adjacent light modules 11, 11a.

Thus, in the case of 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) rail profile interior area 5. Several assemblies 2, 12, in 10 designed as linear lighting modules 11, 11a can be supplied with power from a common adapter unit 7. For example, a total of three modules 11, 11a can be supplied by means of a common adapter unit 17, with a further module 11a being able to be provided at each end of the module 11 in particular, although a longer series with further modules 11a is also conceivable.

In addition, the modules 2, 12 are controlled and operated according to a master-slave principle. The module 2 directly coupled to the adapter component 7 is regarded as the "master", to which the other module(s) 12 indirectly coupled via the module 2 and the devices 15 to the adapter unit 7 are subordinated as the "slave". is. The interpretation of the control signal present on the conductors 6b, for example as a DALI signal, can be carried out by the adapter unit 7 or the first assembly 2 ("master"), with an output signal generated on the basis of the control signal from the adapter unit 7 or the assembly 2 via the device 15 is passed on to the "slave" module(s) 12. In both cases, the assemblies 2 and 12, and therefore the lighting modules 11 and 11a, are controlled via a common address, for example a common DALI address; this address is therefore the adapter 7 or the module 11 and indirectly assigned to the coupled modules 11a. The extension light-emitting module 11a receives not only power but also control signals corresponding to the first light-emitting module 11.

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

For the light module 11 of 10, 12 applies to the above Figures 1-9 Described by analogy. The light module 11a of 10, 12 is also designed analogously to the lighting module 11, the printed circuit boards (“PCBs”) of the further assembly(s) 12, thus of the second and further lighting modules 11a indirectly coupled to the adapter component 7, not necessarily being double-sided. Rather, it may be sufficient if the printed circuit board at the lighting module(s) 11a power supply and operation of the LEDs, which are arranged on the inwardly directed main surface of the printed circuit board as in the lighting module 11, and the power and signal supply via the device (en) 15 allows. Corresponding conductor tracks and devices can be arranged in the lighting module 11a, for example, such as the LEDs, on the inwardly directed main surface of the printed circuit board, especially since a direct conductive connection with contact elements of an adapter unit 7 is not necessary in the lighting module 11a and the contact elements 18 in the lighting module 11a are therefore not required. The printed circuit boards of the lighting module(s) 11a can therefore be manufactured more cost-effectively than those of the lighting module 11 .

In particular, the modules 11, 11a, which are supplied together directly ("master") or indirectly ("slave") by an adapter 7, are switched in the same electrical phase selected by the adapter unit 7 and are supplied via this.

The rail lighting system, based on which the arrangements 1, 1 'are constructed as described above, can alternatively include rail profiles that can be used instead of the rail profile 3 and in 13-16 are shown as examples. The profiles of 13-15 differ from the profile 3 the Figures 1-6 and 10 in that the flanges or side walls 3b are shortened in cross-section towards the visible side, as in 13-14 , or lengthened in cross-section to accommodate deeper assemblies, as in 15 , are trained. 16 shows a variant in which the upper area 5 for accommodating a conductor device 6 with a total of ten conductors, of which 16 only some are provided with reference numbers.

Further variants of the lighting arrangement 1, in which the subassembly 2 and the further subassembly 12 are each designed as a lighting module 11', 11a', are shown 17-22 . The lighting arrangement 1" of 17-22 has a rail profile 3 ', this as mentioned accordingly 15 is formed and from the rail profile 3 of Figures 1-6 , 10 with regard to the side walls or flanges 3b extended towards the visible side S, so that a deeper first region 4 is achieved.

The light module 11' in 17, 18 has a row of reflectors which are open towards the visible side S and which reflect light emitted by the light-generating devices designed as LEDs on the circuit board 21 in a desired manner. With the exception that - instead of lenses and / or an opal or clear cover - the reflectors are provided, and that the arrangement of the LEDs on the circuit board 21 can be suitably adapted to the arrangement of the reflectors, the lighting module 11 'is analogous to that Lighting module 11, as described above, formed.

In 17, 18 devices for frontal electrical coupling are not shown. In 19-22 are, however, analogous to the embodiment of 10, 12 , Devices 15a, 15b are provided on facing front ends of the light-emitting modules 11', 11a' in order to electrically couple adjacent assemblies 2, 12 to one another, analogously to the above Figures 10-12 described. 21 shows adjacent light modules 11 ', 11a' in an assembly step before the electrical coupling of both at their mutually facing end faces, 22 in paired state. The devices 15a, 15b are designed to correspond to one another, for example as plug-in connections. In particular, at least one further module 11a' can be provided at each of the two ends of the module 11'.

The displaceability of the light modules 11 ', 11a' with respect to the adapter unit 7 in the inserted state is in the same way as in the exemplary embodiments of FIG Figures 1-10 given. By after snapping or clipping and in the state of electrical coupling of the adapter unit 7 and the first light module 11 'a longitudinal displacement along the rail profile 3' is still possible, the work steps can 21-22 be carried out in a facilitated manner.

The light modules 11', 11a' are operated, supplied and controlled as shown in FIG Figures 1-12 described. In particular, in 13-22 the conductor device 6 in the second region 5 is designed to provide an electrical AC voltage, for example mains voltage, for example in the range of approximately 220V to 240V, in particular 230V at 50Hz, for the electrical supply. By means of a converter in the adapter unit 7, the high voltage is converted into an electrical direct voltage of less than 60V, for example 48V, for the operation of the luminous components.

A lighting arrangement 1"' according to a further modification of the first exemplary embodiment is shown Figure 44 . Here, the subassembly 2, which in turn is designed as a light module 11, is electrically coupled to an adapter unit 7'" by means of a flexible cable 700. The subassembly 2 wired in this way to the adapter unit 7'" is relative to the adapter unit 7' used. "Slidable along the longitudinal direction L of the rail profile 3 even after the assembly 2 has been inserted into the area 4. The length of the cable 700 and/or the positioning of the same can be selected or varied differently, for example depending on the desired possible displacement path, for example by one to allow better access to a phase selection pushbutton switch on the underside of the adapter unit 7'' when wired. In addition to the above, the lighting module 11 and the adapter unit 7'''' correspond to the lighting module 11 and the adapter unit 7 described above.

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

The lighting arrangement 1a 'of 23 has a rail profile 3 which corresponds to that described for the first exemplary embodiment.

In the second exemplary embodiment, a second, smaller rail profile 9 is accommodated in the first area 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 for at least partially receiving and/or coupling to lighting units 211a, 211b—shown only schematically in the figures. Furthermore, the rail 9 enables the power supply of the lighting units 211a, 211b, and the rail 9 can also provide control signals for the lighting units 211a, 211b coupled to the rail 9 or accommodated by it, the lighting units 211a, 211b being equipped, for example, with suitable devices for electrical and for example, further equipped for mechanical coupling to the rail 9. The lighting units 211a, 211b coupled to the rail 9 are preferably coupled to the rail 9 in a displaceable manner and are provided in particular for direct lighting.

Furthermore, the lighting arrangement 1a' has a connection unit 8', which enables an electrical coupling of the rail 9 and the adapter unit 7'. A subassembly 2 that can be accommodated in the first region 4 of the rail profile 3 is formed here with the rail 9 and the connecting unit 8'. It is preferably provided that the assembly 2, in particular the rail 9, can be latched to the rail profile 3 for mechanical attachment or clipped into the rail profile 3, for which purpose suitable means not shown in the figures can be provided. The mechanical attachment of the subassembly 2 formed with the rail 9 and the connecting unit 8' is designed analogously to the latching or clipping in of the subassembly 2 of the first exemplary embodiment in such a way that even after latching or clipping in, the rail 9 and the connecting unit 8' can be displaced in Longitudinal direction L of the rail profile 3 is possible. In the second exemplary embodiment, too, the locking of the subassembly 2 with the rail profile 3 and the release from this locking requires relatively little force, as a result of which the locking and release can be carried out easily and quickly by an operator or fitter.

The adapter unit 7′ is constructed like the adapter unit 7 in terms of its basic shape and dimensions, mechanical fixing in the outer rail profile 3 and electrical coupling to the conductor device 6, so that reference is made to the above statements in this regard. A converter is arranged inside the adapter unit 7'.

In contrast to the adapter unit 7, the adapter unit 7' is not equipped with selective current collectors for the supply of light modules on its lower side, which faces the visible side S in the assembled state. Instead, the adapter unit 7 'of 23-32 on the underside of the adapter unit 7', i.e. that side which faces the rail 9 when the adapter unit 7' and the assembly 2 comprising the rail 9 and the connection unit 8' are inserted into the rail profile 3, a contact device 1027 with several strip-shaped Contact elements 27 on. The contact elements 27 can each be brought into electrically conductive contact with an associated contact element 28 of the assembly 2 when the assembly 2 is inserted into the rail profile 3 below the adapter unit 7 ′. When the adapter component 7' is inserted into the second area 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.

The first low-voltage rail module, which can be inserted under the adapter unit 7' in the shown section of the rail profile 3 and forms the assembly 2, has a through-opening 10' on the upper side of the rail 9 when installed, the through-opening 10' being in a web 9a of the rail 9 is introduced. After inserting the adapter unit 7' and the assembly 2 in the rail profile 3, the web 9a faces the adapter unit 7'.

In the second exemplary embodiment, the plurality of contact elements 28 of the assembly 2 are arranged on a projection-like contacting section 8a′ of the connection unit 8′. In this case, the contact elements 28 are designed as punctiform, pin-like or pin-head-like contact elements 28 on the upper side of the contacting section 8a′.

By inserting the contact section 8a' into the through-opening 10', the punctiform contacts 28 of the connection unit 8' can each be brought into electrical connection with one of the conductor tracks 27 of the adapter 7' mounted above, in order to electrically couple the assembly 2 to the adapter unit 7' .

The connector 8' serves as a coupling unit and subsequently ensures the supply of the subassembly 2 designed as a low-voltage rail module. Here, the rail 9 of the assembly 2 is provided with a conductor means 26 having low-voltage conductors 26a and control signal conductors 26b along the longitudinal direction of the rail 9 in the second embodiment. A cross section of the rail 9 is in 27 shown and also in the variant of the 23-24 provided in this form and equipment.

The low-voltage rail modules 2 are equipped in this way to receive and power the lighting units 211a, 211b to be operated at low voltage, and to supply the lighting units 211a, 211b on the rail 9 with control signals.

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

The provision of the electric power at low voltage by means of the adapter unit 7', based on the provision of mains voltage via the conductor device 6, takes place by means of a converter of the adapter unit 7' as described above for the first exemplary embodiment. The low voltage for the power supply of the lighting units 211a, 211b is then forwarded to the connection unit 8' via two of the contact elements 27, 28, for example. The selection of an electrical phase with the aid of the adapter unit 7' is also possible, as in the first exemplary embodiment.

In the second exemplary embodiment, control signals provided on the conductors 6b of the conductor device 6, for example a DALI signal, are forwarded unchanged via one or more further corresponding ones of the contact elements 27, 28 to the connecting unit 8'.

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

The connection unit 8' is arranged to receive the electrical energy and control signals from the adapter unit 7', and the electrical energy received via contact elements 27, 28 into the conductors 26a of the conductor device 26 of the rail 9, as well as from the adapter unit 7' via to feed the further control signals forwarded to the contact elements 27, 28 into the conductor 26b. Furthermore, the connecting unit 8 ′ can be latched mechanically to the rail 9 of the assembly 2 .

A variant of the lighting arrangement according to the second embodiment is shown in FIG 25-32 . Except for the differences described below, the above explanations apply to the 23 , 24 also on the lighting arrangement 1a of 25-32 Application.

The lighting arrangement 1a of 25-31 again has a rail profile 3, an adapter unit 7', and an assembly 2. With regard in particular to the design of the rail profile 3 and the adapter unit 7' and their functions, reference is made to the above statements.

The assembly 2 includes the variant of 25-32 again a rail 9 with a conductor device 26 arranged in its inner area 25, which is divided into two and arranged on both sides of the inner area 25, see FIG 27 , and a connection unit 8 - shown enlarged in 31 - on.

The connection unit 8 of 25-32 is of oblong box-like external shape and adapted to be arranged substantially entirely in the inner region 25 of the rail 9, such that the conductors 26a of the conductor means 26 are located laterally of the connection unit 8, cf 27-30 . A first contact device 1030 with contact elements 30, see 31 , is adapted to come into electrically conductive contact with the conductors 26a, 26b of the conductor means 26 extending along the rail 9 when the connection unit 8 is inserted into the inner region 25. Elastically resilient latching elements 31 are used for a preferably detachable clipping of the connecting unit 8 into the rail 9 for the mechanical coupling of the components 8 and 9.

The connection unit 8 also has in 25-32 the function of a coupling unit, which enables the electrical coupling of the rail 9 to the adapter unit 7' for the transmission of power and control signals. The connecting unit 8 has a contacting section 8a which is introduced into a through-opening 10 in the web 3a of the rail 3 when the coupling unit 8 is inserted into the rail 9 . A second contact device 1028 with - in 31 exemplary three - punctual, pin or pin head-like contact elements 28 are provided. The contact elements 28 are designed and arranged to come into electrically conductive contact with a corresponding one of the strip-shaped or web-shaped contact elements 27 of the adapter unit 7'.

The contacting portion 8a is in the example 25-31 , in contrast to the plate-like contacting portion 8a 'in 24 , formed with a smaller base area and with a larger overhang over the remaining upper side of the connecting unit 8, for example, of a cylinder-like 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.

Furthermore, it should be noted that in 25-30 and 32 the adapter unit 7′ is provided with a projection 7a′ approximately centrally in relation to its longitudinal axis, and on its upper side which points towards the web 3a of the rail profile 3 in the assembled state. This can be part of a body and/or housing of the adapter unit 7' and, in further exemplary embodiments, with contact elements instead of the contact elements 27, to be equipped, but in 25-30 , 32 Contact elements on the projection 7a 'are not available. Alternatively, the projection 7a' could be omitted from the adapter unit 7'.

In a variant of the second exemplary embodiment, too, at least one further assembly 12 can be provided, which is supplied via the assembly 2 with electrical energy and control signals that are provided by the adapter unit 7′. Such a lighting arrangement 1a" is in 32 shown. Similar to assembly 2, assembly 12 has 32 a rail 9, with which one or more lighting unit(s), e.g. 211a, 211b (in 32 not shown in detail), can be coupled and/or can be accommodated at least in sections by the further rail 9. The extension rail 9 of the assembly 12 in 32 also has a conductor device 26 analogous to the assembly 2 in 23-31 on. In the area of a joint 1202, the assemblies 2, 12 are coupled to one another in such a way that the corresponding conductors 26a, 26b of the two rails 9 are in electrical contact with one another at their adjacent front ends. For example, suitably designed coupling pieces (not shown in more detail) can be provided at the joints 1202 for this purpose.

In this way, a plurality of low-voltage rail modules in the form of assemblies 2, 12 - for example three such assemblies, such as one assembly 12 at each end of assembly 2 - can be inserted adjacent to one another in the rail profile 3 and electrically connected to one another. The assembly 12 of 32 unlike the assembly 2, has no connection unit 8 or 8'. It is therefore sufficient to use only a first low-voltage rail module, ie the assembly 2 in 32 , to be coupled electrically via the adapter unit 7' arranged above it to the high-voltage rail 3. The low-voltage rail modules 2, 12--whether supplied directly or indirectly by a common adapter unit--are all switched together in the same phase, which can be selected by means of the adapter unit 7'. Electrical power for supplying the lighting units 211a, 211b is passed on to the coupling point 1202 via the conductors 26a. Control signals, such as DALI signals are at the coupling point 1202 via the Corresponding head 26b forwarded unchanged, which can also be located on the extension rail 9 of the module 12 lighting units can be individually controlled via their own addresses.

Out of 32 It can be seen that the rail profile 3 can be formed with a plurality of rail profile sections connected to one another at the ends in order 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) rail profile inner area 5.

This in 23-32 The exemplary embodiment shown, together with its variants, also enables, after inserting the adapter unit 7' and the assembly 2 and, if applicable, the assembly 12 into the rail profile 3, to move the assembly 2 or the assemblies 2 and 12, including the rails 9 and the connecting unit 8 or 8' relative to the adapter unit 7'.

33-37 show a lighting arrangement 1b according to a third exemplary embodiment and a variant 1b' of the same, which can be fastened in a suspended manner and, in addition to luminous components for realizing direct lighting, can be equipped with indirect lighting. The lighting arrangement 1b, 1b 'of 33-37 can, for example, be suspended from a ceiling of a room or another part of a building or from another structure. The indirect lighting is implemented in the arrangements 1b and 1b' in the manner described below.

The lighting arrangement 1b, 1b' of the third exemplary embodiment comprises a rail profile 3", which is analogous to the profile 3 in Figures 1-6 , 10 , 23-32 an area 4 and an inner area 5, the configuration and function of which are described above. However, the rail profile 3" differs from the rail profile 3 in that the rail profile 3" also has a receiving area 44 on a rear side facing away from the visible side S, and thus on the rear of the web 3a is provided. The receiving area 44 is designed in the cross-sectional profile of the rail profile 3" as a flat channel facing away from the second area 5. The rail profile 3" is designed essentially symmetrically to a longitudinal center plane, except for differing end sections of the longitudinal ribs 3c, 3c'.

The receiving area 44 serves as a first area of the rail profile 3" for receiving 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. towards the ceiling of the room, for example.

The rail profile 3" in 33-37 is equipped with a three-phase, or alternatively a five-phase, conductor device 6 set up for mains voltage, analogous to that described above for the profiles 3, 3'. The web 3a delimits the inner, second area 5 equipped with the conductor device 6 at the top and thus separates the receiving area 44 from the inner area 5. At the top, i.e. on the rear side of the rail profile 3" opposite the visible side S, this is one or more through openings 50, see Figure 36 , fitted in the bridge 3a.

Also provided is an adapter unit 7" that can be inserted into the rail profile 3" analogously to the adapter units 7, 7', which is designed analogously to the adapter units 7, 7' in terms of its basic shape, the differences being described below.

The adapter unit 7″ has a contact device 1017a with selective contact elements 17a on the upper side of the adapter unit 7″. Here, the contact elements 17a are pin-like or pin-head-like and protrude from an upper surface of a projection-like contacting section 7a'', which extends essentially like the projection 7a' 32 can be trained. The contacting section 7a" is arranged essentially centrally in relation to the longitudinal extent of the adapter unit 7" on the adapter unit 7" and is provided on the upper side of the adapter unit 7" facing away from the visible side S in the inserted state and facing the web 3a.

The contact section 7a" can be inserted into the opening 50 for the electrical coupling of the indirect light module 40 and the adapter unit 7". Thus, the contact elements 17a, see Figure 33 , through the opening 50 and protrude upwards from it. A body section of the contacting section 7a" preferably essentially fills the passage opening 50, as a result of which this is closed after the adapter unit 7" has been inserted.

Like the adapter unit 7, 7', the adapter unit 7" can basically be freely positioned along the rail profile 3" with the corresponding selection or introduction of the opening 50, but can no longer be longitudinally displaced after the contacting section 7a" has been passed through the opening 50.

The first indirect light module 40, which can be slidably inserted in the rail profile 3", has a double-sided printed circuit board 41 ("PCB"), which is electrically coupled to the protruding contact elements 17a of the adapter unit 7" on its underside via a contact device 1047 having web or strip-shaped contact elements 47 can. Further indirect light modules can each be inserted as an extension indirect light module 40a on the front side adjoining the first indirect light module 40 in the receiving area 44 and connected to the first indirect light module 40 according to a master/slave principle, with the indirect light module 40 being able to be regarded as the "master". The connection can be made at a joint 4040, see FIG 37 , take place. The additional indirect light modules 40a or "slaves" can have at least one-sided printed circuit board instead of the double-sided printed circuit board 41, which can contribute to cost savings and simplified production.

Electrical supply to the indirect light module 40a is mediated via the indirect light module 40, with a low voltage for the operation of the indirect light modules 40, 40a being provided by the adapter unit 7", which contains a converter, as in the first exemplary embodiment. The adapter unit 7" can also be used. the electrical phase to be used for the power supply of the indirect light modules 40, 40a can be selected.

The control of the indirect light modules 40, 40a is made possible in a similar manner to the direct light modules 11, 11a or 11', 11a', with the indirect light modules 40, 40a being addressed via a common address, e.g. a DALI address, and being controlled together. The control signal provided on the conductors 26b of the conductor device 6 is interpreted by devices in the adapter unit 7" or alternatively by devices on the circuit board 41 of the "master" indirect light module 40 and, based on this, an output signal is generated for the controller, with the contact device 1017a for example for the transmission of the output signal generated on the basis of the interpretation of the control signal in the adapter unit 7" or for the forwarding of the control signal picked up by the adapter unit 7" from the conductor device 6. In both cases, the output signal resulting from the interpretation is output at the junction 4040 The output signal can be converted, for example, by means of a pulse width or pulse-pause modulation.

The supply and control of the indirect light module 40 can be achieved in a simple and quick manner. A comparatively small through-opening 50 is made in the area of the upper side of the rail profile 3" in the web 3a. The opening 50 can either be prefabricated or flexibly made on site then positioned in the rail profile 3" under the recess 50. Indirect lighting modules 40 can, for example, then be quickly, variably and flexibly inserted without great effort. In addition, for the indirect lighting module 40 and, if necessary, further indirect lighting modules 40a as "slaves", with the given electrical coupling displacement in the longitudinal direction L relative to the adapter unit 7" is still possible. For example, a further module 40a can be provided at each end of the module 40, with an indirect light strip of greater length also being conceivable.

The adapter unit 7" is thus set up as "slaves" for the supply of the indirect module 40 and, if necessary, further indirect modules 40a in the receiving area 44. In addition to the adapter unit 7" 33-37 another, in 34 , 36, 37 non-visible adapter unit 7 in the second area 5 of the rail profile 3" was added and configured as described for the first exemplary embodiment. Means the other adapter unit 7 can be one or more linear light modules 11, 11a as assemblies 2, 12 analog Figures 1-10 are supplied in order to also implement direct lighting by means of the lighting arrangement 1b, 1b', ie in particular starting from the visible side S into the spatial area below. With such an arrangement 1b, 1b', for example, continuous, direct and indirect light bands can be generated at the same time, which can be moved separately along the rail 3".

In 33, 35 shows the front side of the rail profile 3" with two adapter units 7, 7" used as an example - 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 concealed.

As in the first and second exemplary embodiment, in the third exemplary embodiment the area 4, which is provided for at least partially and preferably essentially completely accommodating the assembly(s) 2, 12, which is/are preferably set up for direct lighting, is designed as a 1b' front area 4 of the rail profile 3". The front side of the lighting arrangement 1b or 1b' corresponds to its visible side S, in particular its underside in an assembled state.

The receiving area 44 for at least partially, preferably essentially completely, receiving 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, the second area 5 being provided between the web 3a and the area 4. The rear first area 44 and the second area 5 are thus adjacent to one another in the third exemplary embodiment and in this case by the web 3a separated from each other.

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

In a variant, however, the contact devices 1017a, 1047 can be connected by a cable analogous to that above Figure 44 Be replaced described, with a sufficient cable length is provided to allow a shiftability of the indirect light module 40 and possibly the extension indirect light module 40a relative to the adapter unit used.

The exemplary embodiments described above show some possibilities for constructing a lighting arrangement based on the rail lighting system described above, with the different assemblies, lighting modules, lighting units, indirect lighting modules and rail profiles described above being able to be combined in many ways in order to meet the lighting requirements in different applications .

In particular, the indirect light module(s) 140, 140a can be made of 33-37 with the referring to 1-32 described direct light modules 11, 11a, 11 ', 11a' or light units 211a, 211b can be combined in a variety of ways. For example, in this way both directly and indirectly illuminated light bands can be realized which, when inserted, can be displaced independently of one another relative to the respectively provided adapter unit 7″ or 7 or 7′.

As described above, for extension rails 9, see 32 , or extension modules 11a, 11a', 40a, see 10 , 19 and 37 , no separate adapter unit required.

However, a specially provided adapter unit is preferably provided for each of the differently configured assemblies 2, 12. For the light modules 11, 11a, 11 ', 11a', for the low-voltage rails 9 with light units 211a, 211b, and for the indirect lighting by means of the indirect lighting modules 40, 40a, the track lighting system provides a specially designed adapter unit 7, 7', 7". In particular with regard to the basic shape and dimensions as well as the attachment in the second area 5 and the contacting with the conductor device 6 Adapter units 7, 7', 7" are designed essentially analogously.

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, for example next to the first adapter unit 7", is used for additional directly illuminating lighting modules 11, 11a or 11', 11a' in the rail profile . To combine the indirect lighting modules 40, 40a with an assembly 2 with the low-voltage rail 9, a second adapter unit 7' can be used in an analogous manner in addition to the adapter unit 7". of the adapter units 7, 7', 7" is limited in terms of electrical and control technology.

Furthermore, the rail system can provide an adapter unit, not shown in detail in the figures, for radiators or "spotlights", also not shown in detail, with such an adapter unit, for example, with the exception of the lack of contact elements 17, being essentially as in Figures 1-22 configured and is additionally equipped on its underside facing the visible side S with a coupling device for mechanically and electrically coupling the spotlight to the adapter unit. The spotlight is not intended to be displaceable relative to the adapter unit. Such spotlights are mechanically fixed in the rail profile 3, 3' or 3'' via the connecting element to the adapter unit and the latter are mechanically fixed in the second area 5.

Alternatively, it is conceivable, for example, to provide contact elements 17a for the supply of an indirect light module and contact elements 17 for the supply of modules 11, 11a, 11', 11a' simultaneously on an adapter unit, for example the adapter unit 7", at the same time. It would be analogous to provide on the adapter unit 7' contact elements 17a are to be provided for an indirect module 40. In such a modification, instead of two Only one adapter unit is required, which, however, is more complicated in terms of electrical and control technology, especially if direct and indirect lighting is to be controlled independently of one another.

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 selective contact elements 17 or 17a, in which case a corresponding number of contact elements 18 or 47 can be provided.

For example, in some variants of the exemplary embodiment, three pin contacts 17 or 17a can be used 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 assignment: first contact element positive (cold); second contact element positive (warm); third contact element negative.

In a variant in which the "Tunable White" option is not available, it may be sufficient to provide the adapter units 7, 7" each with only two contact elements, with the assignment: first contact element positive, second contact element negative.

A track lighting system is thus described above which enables a combinable accommodation of displaceable spotlights, lighting modules and low-current tracks, which themselves can accommodate further lighting units in a particularly displaceable manner, in a three-phase or five-phase track.

A lighting arrangement 100 according to a fourth embodiment, and a variant 100 'of this show 38-43 . The lighting arrangement 100 has a rail 109, at least one indirect lighting module 140 for providing indirect lighting, and an adapter or coupling unit 108.

The rail 109 is designed for coupling and/or at least partially accommodating one or more lighting units 111a and/or 111b, which in 38 are shown schematically and can be of different types, for example as linear modules 111b or spots 111a.

The rail profile 109 has a first area 144 and a second area 125, see the cross-sectional view of FIG Figure 42 . In the inside, in Figure 42 In the lower area 125, a conductor device 126 is provided along the rail 109 to provide at least electrical energy for the supply of the lighting unit(s) 111a, 111b. The conductor device 126 extends parallel to a longitudinal direction L' of the rail profile 109. In 42, 43 shows that the conductor device 126 is formed with two busbars, each with two conductors 126a, 126b, one busbar on each side of the inner region 125 laterally within it, with the conductors 126a providing the electrical current and the conductors 126b of the Provision of a control signal, such as a DALI signal, are used, with a control signal based on another protocol or dimming method, for example, also being conceivable. If, for example, a control signal is not desired, the conductor means 6 could alternatively be designed with only one busbar on one side, and with a total of two conductors.

The rail 109 is designed as a low-voltage or low-voltage rail, for example for supplying energy to the lighting units with a DC voltage of less than 60V, for example 48V, which is fed into the conductor device 126 by a feed unit (not shown).

The adapter unit 108 can also be referred to as a coupling or connection unit, is used to electrically couple the conductor device 126 to the indirect light module 140, can be inserted into the inner region 125 of the rail 109 and can be coupled to the rail 109. In the inserted state of the coupling or adapter unit 108, the conductors 126a, 126b are arranged on the side of the unit 108.

In the Figure 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 set up to make electrically conductive contact with one of the conductors 126a, 126b. In addition, the coupling unit 108 has elastically resilient latching elements 131 on its longitudinal sides, by means of which the unit 108 can be clipped into the rail 109 from the visible side S of the latter for mechanically coupling it to the rail 109 .

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

A cross-sectional shape of rail 109 is formed with a web 109a and sidewalls or flanges 109b, with web 109a extending between flanges 109b. The web 109a delimits the inner, second region 125 of the rail 109, which is equipped with the conductor device 126.

The track 109 is suspended to form the lighting assembly 100, for example in a building, for example by suspending the track 109 from a ceiling, from another component of the building, or from another structure.

The first area 144, also referred to below as the receiving area 144, is arranged on a rear side of the rail 109 which faces away from a visible side S of the rail 109 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 the opening of the same towards the web 109a, the channel has two sections of different widths and is of smaller width towards the web 109a due to inwardly projecting, lateral steps.

The receiving area 144 serves to receive an assembly 2 designed as an elongate indirect light module 140, which—in 42, 43 from above - in the receiving area 144 can be used. In the assembled state, the indirect light module 140 inserted in the first region 144 can emit light upwards, that is to say, for example, in the direction of the ceiling of the room.

In order to supply the indirect light module 140 with electrical power and preferably with control signals, the unit 108 has a contacting 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 contacting section 109 is inserted into the through-opening 110 in such a way that the upper part of the contacting section 108a passes through the through-opening 110 in order to supply the indirect light module 140 with electrical power and preferably also with the control signals.

The indirect light module 140 has a double-sided circuit board 141 . On a main surface of the printed circuit board 141 facing 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, which extend parallel to the longitudinal direction L′ and are designed as conductor tracks. On the other, opposite main surface, the printed circuit board 141 is equipped with light-generating devices, which are preferably designed as LEDs.

On the contact section 108a of the adapter unit 108 there is a second contact device 1128 with a plurality of, in the example shown three, punctiform, pin-like or pin-head-like contact elements 128 which protrude from an upper surface of the contact section 108a in the assembled state, see Figure 39 .

When the unit 108 is inserted, the second contact device 1128, comprising the contact elements 128, makes electrically conductive contact with the contact device 1147 of the indirect light module 140, comprising the contact elements 147. In particular, each contact element 128 makes contact with one of the web-like contact elements 147.

Complex cabling of the indirect light module 140 is therefore necessary in the described embodiment with the interacting contact devices 1128, 1147 not necessary, the electrical coupling of the conductor device 126 to the indirect lighting module 140 is possible in a simple and time-saving manner. The through opening 110 with a relatively small size can be prefabricated in the rail 109 or can be introduced flexibly at the construction site. After that, the indirect light module 140, and possibly further indirect light modules 140a, see the variant of Figure 41 , can be inserted quickly, variably and flexibly with little effort.

In addition, the punctiform contact elements 128 can slide on the web-like contact elements 147 in the touching state, as a result of which the indirect light module 140 can be displaced relative to the coupling or adapter unit 108 in the inserted state.

Figure 41 12 illustrates that in a lighting assembly 100' according to one variant, the indirect light module 140 may form a first indirect light module 140 electrically coupleable to at least one extension indirect light module 140a. For this purpose, the extension indirect light module 140a can be inserted into the receiving area 144 like the indirect light module 140 . In this way, a joint 1414 is formed between the modules 140, 140a, which Figure 41 is not yet fully closed. The modules 140 and 140a can be electrically coupled to one another at the joint 1414 in order to likewise supply the extension indirect light module 140a with electrical energy via the indirect light module 140 by the unit 108 .

The modules 140 and 140a are controlled and operated according to a master-slave operation, with the module 140a as "slave" being subordinate to the module 140 as "master". In other words, the extension indirect light module 140a is controlled according to those control signals which the first indirect light module 140 receives from the adapter unit 108 and according to which the first indirect light module 140 is controlled and operated.

The preferably double-sided circuit board 141 ("PCB") of the first indirect light module 140 allows in the embodiment of 38-43 not only the power supply of the module 140, but also interprets control signals, which are mediated via the contact devices 1130, 1128 and 1147 from the conductor device 126 can be forwarded to the first module 140 via the unit 108, and in this way enables control, for example dimming. The module 140a ("slave") is also controlled in the same way as the module 140 via the frontal coupling to the module 140a. The control signal forwarded by the conductors 126b is evaluated by devices of the first indirect light module 140 ("master"), these devices being used to generate an output signal based on the control signal, which is used by module 140 to control the same and also at junction 1414 the extension module 140a is passed on for its control. The output signal is, for example, a signal that correlates with the dim level, for example based on pulse width modulation or pulse-pause modulation. The modules 140, 140a can thus be controlled via a common address.

The one or more extension indirect light modules 140a can be attached to the module 140 in a connectable manner according to the master/slave principle described above and therefore do not require a separate coupling unit. At least one extension module 140a at each end of the module 140 is conceivable.

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

Although above the use of wiring 700 for electrical coupling only with reference to FIG Figure 44 was described, it should be noted that cabling 700 is also conceivable in an analogous manner in the other exemplary embodiments described above as an alternative way of displaceable electrical coupling. While punctiform contact elements that can be slid on strip or web-shaped contact elements, as described above, enable particularly simple and quick assembly, the alternative use of a cable 700 can be particularly inexpensive and at the same time the slidable electrical coupling of the adapter unit 7, 7', 7", 7′″ and the assembly, or the adapter or coupling unit 108 and the assembly, in the exemplary embodiments described above, with little effort.

Although the invention has been fully described above with reference to preferred exemplary embodiments, it is not restricted thereto but can be modified in a variety of ways.
