Description

FIELD OF THE INVENTION

The invention relates to the field of lighting arrangements and refers here to a lighting arrangement, to a kit for use in a lighting arrangement, and to a node element for a lighting arrangement.

TECHNICAL BACKGROUND

Lighting systems with rails and with lighting devices that can be coupled to the rails are well known. Such lighting arrangements find, for example, in the illumination of rooms in buildings, such as the illumination of business premises, offices, showrooms or living rooms, application. In order to create attractive lighting solutions with which desired areas and / or objects can be specifically and effectively illuminated, it may be desirable to connect rails of such lighting systems not only in a straight line, but also at an angle.

The applicant is aware of connectors for rail systems which make it possible to couple together rails of a lighting system at a defined angle. However, in these systems, the combination of rails to a pattern or the like often only very limited possible. Moreover, in the case of conventional rail systems, it is often difficult to change the coupling of the rails with each other in the event of changing lighting requirements, as can occur, for example, when lighting a shop. Conventional rail systems often prove to be relatively inflexible in this regard. In particular, in conventional rail systems connectors are often limited to a defined number of rails to be connected to the connector.

In the DE 10 2014 003 251 A1 For example, a light system is further described in which a connector or node is provided, which has a rotationally symmetrical about a connector central axis element and at least one mechanically connected to the revolving element electrical conductor. Here, a lamp unit with the connector is mechanically and electrically connected. The angles at which rails can be infected at junctions should be largely freely selectable. That in the DE 10 2014 003 251 A1 However, described light system is relatively complex and complicated structure.

This is a condition to be improved.

SUMMARY OF THE INVENTION

Against this background, the invention has for its object to propose an improved lighting arrangement, which makes it possible to arrange rails in many ways combined with each other and is more flexible in the application and also has a simpler structure than known lighting systems.

According to the invention this object is achieved by a lighting arrangement with the features of claim 1 and / or by a kit with the features of claim 14 and / or by a node element with the features of claim 15.

Accordingly, a lighting arrangement is proposed which has at least one rail, at least one node element, at least one adapter and at least one connecting component. The rail has a conductor device for supplying at least one lighting device which can be coupled to the rail with electric current for the operation of the lighting device and / or with a switching and / or control signal. The node element has a first portion, a second portion and a ring-like conductor device. Here, the first and second sections are arranged one above the other in the direction of a central axis of the node element. The node element further has an intermediate A space formed in a portion of the first portion and a portion of the second portion that extends along a circumferential direction of the node member. The adapter mechanically couples the rail and the node element together. The connection component is inserted in sections into the rail and the intermediate space of the node element and electrically couples the conductor device of the node element with the conductor device of the rail. In this case, a first contact device of the connection component in the intermediate space of the node element is in contact with the conductor device of the node element. A second contact device of the connection component is in contact with the conductor device of the rail.

In addition, a kit for use in a lighting arrangement is proposed which comprises a node element, an adapter and a connection component. The node member has a first portion, a second portion, and a ring-like conductor device, wherein the first and second portions are stacked toward a center axis of the node member, and the node member is formed between a portion of the first portion and a portion of the second portion Having along a circumferential direction of the node element extending gap. The adapter is adapted to mechanically couple together a rail of the lighting assembly and the node element. The connection component is designed such that the connection component can be inserted in sections into the rail and into the intermediate space of the node element in order to electrically couple the conductor device of the node element to a conductor device of the rail. The connection component has a first contact device and a second contact device, wherein the first contact device of the connection component in the intermediate space of the node element can be brought into contact with the conductor device of the node element and wherein the second contact device of the connection component can be brought into contact with the conductor device of the rail.

Furthermore, a node element is proposed for a lighting arrangement, wherein the node element has a first portion and a second portion and the first and second portions are arranged one above the other in the direction of a central axis of the node element. The proposed node element has a space formed between a portion of the first portion and a portion of the second portion, extending along a circumferential direction of the node member. The first portion of the node element has fastening means for attaching at least one adapter for mechanically coupling the node element to a rail of the lighting arrangement. The fastening devices are in this case arranged in an annular region around the central axis. In addition, the node element has an annular conductor device, which is arranged on the second section such that a contact region of the conductor device faces the intermediate space. The node element is designed such that after attachment of the adapter to the first portion, a connecting component can be inserted into the intermediate space in sections and a contact device of the connecting component in the intermediate space of the node element with the conductor device of the node element can be brought into contact.

An idea on which the invention is based is to make it possible to connect a variable number of rails to the node element with the aid of the ring-shaped conductor device and the intermediate space. In this case, the angular arrangement of the rails can be selected in different ways to one another, whereby different rail patterns become possible with one and the same node element, and in combination with a variable number of rails coupled by means of the node element. Also can be easily changed with the help of the versatile node element, the coupling of the rails on the node element and thus the pattern. The node element in the invention is not limited to a pre-determined number of rails to be connected thereto, but it could be added to the node element, for example, in the course of alterations, or added as needed for the changed one Patterns are removed instead. Already in the planning a high flexibility of the illumination arrangement of the invention is given.

A coupling of busbars at different angles is made possible in the invention using the node element as well as an adapter and a connecting component for each rail end to be connected. In this case, in particular, a separation of a mechanical coupling of the rails of the electrical connection can be achieved. The mechanical coupling can be effected by means of the adapter, while the connecting component causes the electrical coupling for the supply of electric current for the operation and / or with the switching / control signal. This contributes to a simple construction of the lighting arrangement, since the functions of the mechanical and electrical coupling of the rail to the node element need not be combined in a single component. The adapter and the connection component can each be well adapted to the mechanical or electrical requirements. Mechanical and electrical coupling can be done in succession in two operations.

It is understood that the node element according to the invention can be used in the lighting arrangement according to the invention and the kit according to the invention, and that the kit according to the invention can be used to construct a lighting arrangement according to the invention.

The term of a ring-like conductor means is present annular, such as annular, closed conductor devices - for example, with ring-like conductors - include, and should also include conductor devices, which are formed substantially annularly circumferential, in which the conductor device or the / the head but one Gap - for example of limited extent - may / may have.

Advantageous embodiments and further developments will become apparent from the dependent claims and from the description with reference to the figures of the drawing.

In one embodiment, the first and second contact devices of the connection component are arranged on opposite sides of the connection component. This can further facilitate the electrical coupling to the conductor device of the rail and to improve the contact of the contact device with the associated conductor device when inserting the connection component.

In one development, the connection component is formed with a flat basic shape, wherein the first contact device for making contact with the conductor device of the node element is arranged on a first main surface of the connection component and the second contact device for establishing the contact with the conductor device of the rail on a second main surface the connection component is arranged. In particular, in this case the second main surface of the first main surface is aligned substantially opposite.

In one embodiment, the conductor devices of the rail and of the node element in each case have conductors that are configured to conduct electrical current for the operation of the illumination device and / or a switching and / or control signal. Furthermore, in this case, the first and second contact devices each comprise contact elements which are set up and coupled such that the conductors of the conductor devices of the rail and of the node element corresponding to one another can be brought into electrical connection with one another by means of the inserted connection component.

In one embodiment, the conductor device of the node element has at least two conductor tracks for conducting electrical current for the operation of the illumination devices. Alternatively or additionally, in this embodiment, the conductor device has at least two conductor tracks for conducting a switching and / or control signal. In particular, the conductor device of the rail may also have at least two conductors for conducting electrical current for the operation of the illumination devices and / or at least two conductors for conducting a switching and / or control signal.

In a preferred embodiment, the conductor devices of the rail and the node element are each formed with a plurality of conductors, and are adapted for conducting the electrical current for the operation of the illumination device and for conducting the switching and / or control signal. Thus, it is expedient both to supply the illumination device (s) with power for their operation and to provide the switching and / or control signal for the illumination device (s).

The electrical current for the operation of the illumination device (s) may, in particular, be direct current, for example at a voltage of 48 V.

Furthermore, the switching and / or control signal may in particular be a DALI signal.

In particular, the conductor device of the node element is arranged facing the intermediate space, contact surfaces of the conductor device preferably being exposed to the intermediate space. This contributes to easy production of the contact with the conductor device of the node element.

The conductor device of the node element may be formed in particular annular.

In one embodiment, the conductor device of the node element can be arranged in a plane that is substantially transverse to the central axis of the node element. As a result, the variable connection of the rail to the node element can be further facilitated.

In a development, the conductor device of the node element is arranged on a printed circuit board that is at least partially exposed to the intermediate space. Thus, the conductor device can be conveniently prepared and installed in the node element.

In one embodiment, the conductor device of the node element has two or more conductor tracks, which are arranged essentially concentrically to each other, for example circular-ring-shaped. Thus, the conductor device of the node element can be equipped in a space-saving manner with a plurality of conductors which are contacted by different angular positions about the central axis of the node element in the same way. The conductor tracks of the conductor device of the node element are arranged in particular substantially in one plane, which further simplifies, for example, the production of the conductor device.

In one configuration, the first portion of the node element is formed as an upper portion of the node element, the second portion of the node element is formed as a lower portion of the node element, and the conductor device of the node element is arranged on an upper side of the second portion of the node element facing the first portion of the node element , This may for example contribute to an advantageous production of the contact with the conductor device of the node element and also to a low visibility of this conductor device.

In one embodiment, the connecting component has at least one latching device by means of which the connecting component can be latched to the rail. In this case, the rail can in particular be provided with longitudinal ribs or longitudinal grooves which can be engaged behind by the latching device in order to latch the connecting component to the rail. With this configuration, the connecting member holds after insertion of a simple and fast way to the rail. Preferably, the connection component with the rail is releasably latched. Thus, for example, a conversion is easier if necessary.

In one embodiment, the adapter has a first adapter section which is fastened to the node element in an end region thereof. In particular, the first adapter portion in the end portion thereof is adapted to be fastened to the node member. For example, the end region for this purpose have a passage opening, for example a through-bore. Further, in this embodiment, the adapter has a second adapter portion which extends transversely to the first adapter portion from the first adapter portion, wherein the second adapter portion has a passage through which the inserted connection member extends in sections into the space of the node element. In particular, the passage of the second adapter section is designed to correspond to the connection component such that in a state of the adapter mechanically coupled to the node component, the connection component can be inserted through the passageway and partially into the intermediate space of the node element. Thus, even after the mechanical coupling of rail and node element, the electrical coupling can be achieved in a further step. The passage of the second adapter portion may also advantageously cause an additional guidance of the connecting member when inserting the same.

In a further embodiment, the connection component has a further latching device, which is set up in such a way that the connection component can engage behind the adapter by means of the further latching device in a latching manner. In particular, the further latching device can be configured to latchingly engage behind an edge section of the passage of the second adapter section.

In one embodiment, it is provided that the second adapter section essentially closes an end face of the rail facing the node element, with the exception of the passage. Thus, the rail is cleanly closed at the front end and it can be a defined, aesthetic connection of the rail to the node element can be achieved while the passage also allows passage of the connecting member. In particular, the second adapter portion may be correspondingly formed, for example concave, on a side of the outer shape of the node element facing the node element.

In particular, in one development, the second adapter section may extend along an outer side of the node element away from the first adapter section when the adapter is coupled to the node element. This can further improve the appearance in the connection area of the node element with the rail. In addition, this refinement can contribute to improving the mechanical stability of the lighting arrangement in the region of this connection point. For example, the second adapter portion in the mounted state on the outside of the node element regions abut.

In particular, the first adapter section may extend substantially parallel to a longitudinal direction of the rail when the rail and the adapter are coupled to the node element. Such a first adapter section can be mechanically coupled to the rail in a particularly simple manner.

In one embodiment, the node element is designed as a connecting element, wherein it is provided that the node element electrically couples together mutually associated conductors of the conductor devices of rails coupled to the node element. In this way, it can be advantageously made possible for the operating voltage for the lighting device (s) or the switching and / or control signal or both to be present at the conductor devices of the rails connected to the node element.

In one embodiment, the node element is designed as a supply element and supplies the at least one rail of the lighting arrangement with the electric current for the operation of the illumination device and / or with the switching and / or control signal. Thus, separate feed elements are not needed, but a node element of the lighting arrangement can advantageously take over the feed function.

In a development, at least one feed line for the electric current for operating the lighting device and / or for the switching and / or control signal is led out of the node element through the first section of the node element. Thus, in a simple manner, the node element with the electrical energy to be fed into the conductor devices of the rails or the switching and / or control signal or both are supplied. The feed line may be formed, for example, as a flexible cable. In variants, separate feed lines, in particular separate cables, for the operating current on the one hand and the switching and / or control signal to the other can be provided.

In embodiments of the lighting arrangement, the first portion of the node element is provided with fastening means for attaching at least one adapter for mechanically coupling the node element to the rail of the lighting arrangement, wherein the fastening means are arranged in an annular region around the central axis. The adapter is fastened here by means of the fastening device to the node element.

In one embodiment, the fastening devices of the first section of the node component are formed as bores, in particular as threaded bores. This allows a simple way a secure coupling of the adapter with the node element.

The fastening means of the first portion of the node element may, for example, be distributed at regular or irregular intervals around the central axis of the node element. For example, some or all of the fasteners may be disposed at angular intervals of substantially 30 degrees between adjacent ones of these fasteners about the central axis of the node member. Alternatively, a first angular distance, for example of substantially 30 degrees, may be provided between some adjacent ones of the fastening devices, while a second angular distance, for example of substantially 60 degrees, may be provided between other adjacent ones of the fastening devices. However, other angular distances are also conceivable. Thus, a variety of mounting pattern for rail to be connected can be realized.

In one embodiment, the first section of the node element points away from a visible side of the illumination arrangement, while the second section of the node element faces toward the visible side of the illumination arrangement. In particular, with this embodiment, an expedient arrangement of the aforementioned fastening devices of the first section and a low visibility of the same can be achieved.

In one embodiment, the first and the second portion of the node element are each formed with a substantially round outer shape or with a polygonal outer shape. The outer shape may, for example, seen in the direction of the central axis of the node element, circular or alternatively polygonal, for example, regularly polygonal, such as hexagonal, be formed.

In a preferred embodiment, the first and second sections of the node element are each formed with a substantially cylindrical outer shape.

In an alternative development, the first and the second portion of the node element may each be formed with a prismatic outer shape.

For example, in particular, the above-mentioned round or cylindrical outer shape advantageously facilitate the coupling of the rails with the node element in a variable manner and in different angular positions about the central axis. However, the polygonal or prismatic outer shape may also be useful and aesthetic.

In a further embodiment, an extension of the first section along the central axis of the node element may be less than an extension of the second section along the central axis of the node element. In this way, for example, in the second section space for other components, such as electrical and / or electronic components, created.

In one embodiment, the node element has a mounting device for the direct or indirect attachment of the node element to a building. In this way, the node element can be held on the building. For example, the mounting device for a suspended mounting of the node element to the structure, such as a raw ceiling of the building, be set up. Alternatively, however, the mounting device for a direct mounting of the node element on the building, for example on the raw ceiling, be formed.

In particular, in one embodiment, the lighting arrangement has a plurality of rails which are arranged together with the node element or a plurality of the node elements in a particularly horizontal plane. The invention thus enables in the particular horizontal plane a flexible design of a lighting arrangement.

In one embodiment, a plurality of rails, in particular two to six rails, are coupled to the node element in the lighting arrangement. The node element is in this case designed such that it the mechanical and electrical Coupling of two to six rails with the node element allows. Thus, many possibilities are opened with regard to the connection of rails to the node element. On one node element of the same type, one, two, three, four, five or six rails could be coupled together as needed. Other numbers are also conceivable, where appropriate, the dimensions of the node component and the rails are suitably adapted for this purpose.

The rail or the rails extending or extend in the illumination arrangement in a preferred embodiment in each case radially from the node element.

In one embodiment, the rail is channel-like. In particular, in this case the conductor device of the rail is arranged in the bottom of the channel. This contributes to a simple, functional and aesthetic coupling of the illumination device (s) with the rail, for example by inserting the illumination device (s) into the rail at least in sections.

In one embodiment, the illumination device is coupled to the rail by means of magnetic force. In particular, the lighting arrangement can have a plurality of lighting devices coupled to the rail by magnetic force. The lighting device (s) can be or can be attached to the rail in a simple manner, and in particular detachably. A displacement of the lighting device (s) is easily possible if necessary and further improves the flexibility of the lighting arrangement.

The electrical coupling of the node element to the rail does not necessarily always include the electrical current for the operation of the lighting device (s) and the switching and / or control signal, but in variants of the invention, the electrical coupling described above, only the operating current or just a switch - and / or control signal. Accordingly, in such variants, the number of conductors and the contact elements may vary.

It is understood that the above embodiments and developments can each apply analogously to the lighting arrangement, the kit and the node element of the present invention.

The above embodiments and developments can, if appropriate, combine with each other as desired. Further possible refinements, developments and implementations of the invention also include combinations of features of the invention which have not been explicitly mentioned above or described below with regard to the exemplary embodiments.

DESCRIPTION OF EMBODIMENTS

1 shows a lighting arrangement 1 according to an embodiment. The lighting arrangement 1 has a variety of rails 200 on, by means of several node elements 100 are coupled together to form a rail pattern or system. In the 1 shown arrangement of the rails 200 is mediated via the node elements 100 over ropes 132 on a building 600 attached. In particular, the node elements 100 with which the rails 200 are coupled, from a raw ceiling of the building 600 suspended. The lighting arrangement 1 the 1 thus comprises a rail system, wherein in the rails 200 lighting equipment 500 of which in 1 only a few are shown by way of example, and each with a rail 200 are coupled. In the lighting units 500 For example, it can be elongated, completely in the rail 200 used lighting units, or to spots or spotlights, some of the rail 200 protrude, but other types of lighting devices are conceivable. The lighting equipment 500 are in the example of 1 by magnetic force with the respective associated rail 200 coupled. Out 1 will also be apparent that the rails 200 from the node element 100 or the node elements 100 with which or the rail 200 is respectively coupled, each extending radially, wherein the rails 200 together with the node elements 100 in an in 1 unspecified, in particular horizontal plane lie.

One of the node elements 100 the 1 is in the 3 and 4 shown in more detail. The node element 100 has a first section 103 and one with the first section 103 coupled second section 106 on, which are each formed with a cylindrical outer shape. The node element 100 thus points in the direction of a central axis 119 of the node element 110 considers a substantially circular outer shape. The first paragraph 103 and the second section 106 are in the direction of the central axis 119 of the node element 100 arranged one above the other, wherein the central axis 119 in 1 is substantially parallel to a vertical direction.

3 and 4 further show that an extension of the first section 103 along the central axis 119 is less than an extension of the second section 106 along the central axis 119 , In this way, the first section has 103 the basic shape of a cylinder whose length is considerably smaller than its diameter, whereas the ratio of the length of the second section 106 along the central axis 119 to the diameter of the second section 106 is significantly larger than the corresponding ratio in the first section 103 , The diameters of the sections 103 . 106 are in 3 . 4 essentially the same.

In the in 1 shown arrangement 1 are the node elements 100 arranged such that the first section 103 each from a visible side S the lighting arrangement 1 points away, therefore, to the building 600 is directed while the second section 106 to the visible side S has. Thus, the first section forms 103 an upper portion of the node element 100 while the second section 106 forms a lower portion of the same.

Between a ring-like outdoor area 104 of the first section 103 and also a ring-like outdoor area 107 of the second section 106 is a gap-like gap 110 formed, extending along a circumferential direction 121 of the node element 100 around the node element 100 and the central axis 119 extends completely around.

The node element 100 has an annular conductor device 115 on, the one at the first section 103 facing top 108 of the second section 106 is arranged, and in a plane substantially transverse to the central axis 119 lies, is arranged. A contact area 118 the conductor device 115 is the gap 110 facing.

The ladder device 115 is on a circuit board 114 arranged, which to the gap 110 at least partially exposed. In this case, the conductor device 115 in 3 four tracks 116 . 117 on, each of which is annular and concentric with each other and in a plane on the circuit board 114 are arranged. Essentially annular contact surfaces of the conductor tracks 116 and 117 the gap 110 facing conductor device 115 lie here to the gap 110 free.

From the tracks 116 . 117 serve two tracks 117 in which it is the externally arranged two conductor tracks - in other words, in the radial direction of the node element 100 seen the innermost and the outermost trace - acts as a conductor for conducting electricity for the operation of the lighting equipment 500 , This will be explained in more detail below. The two radial middle conductor tracks 116 form conductors, which are provided, a switching and / or control signal for switching and / or controlling the lighting devices 500 to lead. In the electric power for the operation of the lighting equipment 500 this is the example of 1 to DC, which is provided at a DC voltage of 48 volts. The switching and / or control signal for the lighting devices 500 is a DALI signal in the described embodiment.

The rails 200 each have a conductor device 215 on which in 1 only schematically indicated. The ladder device 215 is set up, each in the rail 200 used, coupled with this lighting device 500 with the electric power for their operation and also to supply the switching and / or control signal. The ladder device 215 is at each of the in 1 shown, channel-like rails 200 each in a reason 206 the channel shape arranged, see also 14 , and therefore in 1 only schematically shown in dashed line.

Each of the ladder devices 215 the rails 200 again four points in the longitudinal direction of the rail 200 extending ladder 216 and 217 on, their contact surfaces to an interior area 203 the channel-like rail 200 lying down. This again serve two conductors 216 conducting the electric current for the operation of the lighting devices 500 , here for example at a DC voltage of 48 volts, while the other two conductors 217 for conducting the wired switching and / or control signal, here by way of example the DALI signal, for switching and / or controlling the lighting devices 500 are provided.

The node element 100 the 3 and 4 is as a supply element 101 designed and set up to the node element 100 electrically coupled rails 200 with the electric power for the operation of the lighting equipment 500 and to supply with the switching and / or control signal. In 1 is such a supply element sketched in which - as in 3 for example, shown in more detail - a feed line 128 , such as a flexible cable, both for the electric power for the operation of the lighting equipment 500 as well as for the switching and / or control signal, through the first section 103 from the node element 100 upwards, and thus from the visible side S gone, is led out.

1 also shows two further node elements 100 , each as connecting elements 102 are formed, and the mutually associated the ladder 216 the ladder devices 215 those rails 200 attached to the connecting element 102 are each connected, as well as the associated conductor 217 the ladder devices 215 of these rails 200 , each electrically couple with each other.

The as a supply element 101 trained node elements 100 , and as a connecting element 102 trained node elements 100 , thus differ only in that the supply elements 101 in addition the feed-in line 128 and optionally, in addition to the circuit board 114 , other electrical and / or electronic components 178 , see also 12 for providing the electrical current and the switching and / or control signal present in the second section 106 can be accommodated. In addition, the connecting elements 102 and the supply elements 101 formed in the same way. That as a supply element 101 trained knot element 100 thus assumes the function of feeding the operating voltage and the switching and / or control signal into the lighting arrangement 1 in other words, in the rail system, while the others, as connecting elements 102 trained node elements 100 Represent distribution nodes that provide the electrical current for the operation and the switching and / or control signal to the conductor devices 215 also indirectly to the supply element 100 connected rails 200 make available.

A mechanical coupling of a rail 200 with a node element 100 is in the lighting arrangement of 1 by means of an adapter 300 causes, whereas an electrical coupling of the conductor device 215 the rail 200 with the conductor device 115 of the node element 100 by means of one of the adapter 300 separately provided and separately usable connection component 400 is achieved.

The adapter 300 is in the 5 and 6 shown by way of example. In particular, the adapter has 300 an asymmetrical T-like basic shape, with two interconnected adapter sections, a first adapter section 303 and a second adapter section 306 , is formed. The two adapter sections 303 and 306 are each formed flat and elongated, with the second adapter section 306 transverse to the first adapter section 303 extending from this path. In one end 304 of the first adapter section 303 this is set up for that, at the node element 100 to be attached. For this purpose, the end region 304 a through hole 315 which is substantially parallel to the longitudinal extent of the second adapter section 306 through the end area 304 extends through. The second adapter section 306 points, in the example shown in the first adapter section 303 adjacent upper half, one passage 310 whose function will be explained in more detail below.

The adapter sections 303 and 306 are with the adapter 300 connected such that by the asymmetric T-like shape two different lengths sub-areas 304 . 305 of the first adapter section 303 To be defined. The shorter of the two subregions forms the end region 304 while the longer of the two subregions in the 5 and 6 with the reference number 305 is designated and designed for, with the rail 200 be mechanically coupled. These are in the longer part 305 several through threaded holes 321 provided that an attachment of the adapter 300 at the rail 200 allow.

On the same side on which the second adapter section 306 from the first adapter section 303 extends, is the end area 304 with a step which a the second adapter section 306 facing convex surface 336 has formed. Furthermore, the end region 304 at its from the second adapter section 306 weggewandten end a concave surface 337 on. One in the direction of the end area 304 facing side of the second adapter section 306 is at the in 6 illustrated example along substantially the entire length of the second adapter portion 306 with a concave and the outer shape of the node element 100 corresponding surface 345 educated.

Basic body of the node element 100 , the adapter 300 as well as the rail 200 are formed in the example shown with a metal material.

The connection component 400 the 7 and 8th is formed with a flat and elongate housing, which may be made of plastic, for example, and two substantially parallel, flat, first and second major surfaces 445 and 446 which is on opposite first and second sides 410 . 415 of the connection component 400 are located.

The connection component 400 has a first contact device 403 and a second contact device 406 on. The first contact device 403 is used to make a contact with the conductor device 115 of the node element 110 while the second contact device 406 the production of a contact with the conductor device 215 the rail 200 serves. The contact device 403 is with four contact elements 421 and 422 formed, wherein two contact elements 421 and two contact elements 422 are provided. The contact elements 421 . 422 are formed like a pin and stand out of the housing of the connecting member 400 on the first main surface 445 in front. The second contact device 406 is on the second main surface 446 arranged and with four contact elements 428 . 429 educated. There are two elongate contact elements 428 and between the contact elements 428 two pin-shaped contact elements 429 intended. The contact elements 428 serve for contacting the conductors 216 while the contact elements 429 the contacting of the conductors 217 serve. The contact devices 403 . 406 are thus on opposite sides 410 . 415 of the connection component 400 arranged, wherein the first contact device 403 on the first page 410 and the second contact device 406 on the second page 415 are arranged.

The connection component 400 is also an end region 401 of the connection component 400 adjacent to opposite narrow sides with locking devices 431 equipped, by means of the connecting component 400 with the rail 200 is releasably latched. The locking devices 431 can by pressing an actuator 432 be solved again.

In addition, the connecting component 400 in the area of the second main surface 446 and in one end area 402 of the connection component 400 , in which further on the first page 410 the first contact device 403 located, another latching device 460 on, which is designed as a resilient tongue, see 8th ,

The 9 and 10 show by way of example a section of a rail 200 by means of an adapter 300 and a connection component 400 with a in this example representation as a supply element 101 trained node element 100 is coupled. However, the mechanical and electrical connection takes place in the same way in the case of a node element 100 acting as a connecting element 102 as described above. The presentation of the 9 and 10 serves as an example of the illustration of the connection of the rail 200 to the node element 100 However, it goes without saying that more rails 200 with the node element 100 can be coupled in the same way. The better overview is in the 9 . 10 only one rail 200 shown.

The mechanical coupling of the rail 200 with the node element 100 is by means of adapter 300 causes. The first paragraph 103 of the node element 100 points in an annular area 145 around the central axis 119 around fasteners 136 on, which are executed in the example shown as threaded holes. The fastening devices 136 are unevenly distributed around the central axis in the example shown 119 arranged around, wherein between some adjacent one of the fastening means 136 an angular distance about the central axis 119 of 30 degrees, and between other adjacent fasteners 136 in angular distance around the central axis 119 is provided by 60 degrees. At the first section 103 like this one in the 3 and 9 is exemplified, are a total of eight fasteners 136 provided and around the central axis 119 arranged around. This is an in 9 example drawn angle W substantially 30 degrees, while an adjacent, also exemplary drawn angle W ' is essentially 60 degrees. The sequence of angles between each fastener 136 along the circumferential direction 121 is in this example as follows, where the names ( B1 ) to ( B8 ) each for a fastening device 136 stand: ( B1 ) - 60 ° - ( B2 ) - 30 ° - ( B3 ) - 30 ° - ( B4 ) - 60 ° - ( B5 ) - 60 ° - ( B6 ) - 30 ° - ( B7 ) - 30 ° - ( B8 ) - 60 ° - ( B1 ).

In addition, the first section points 103 on his from the gap 110 away side facing an axially projecting edge 146 on top of the central axis 119 and the annular area 145 surrounds.

For mechanical coupling of the rail 200 with the node element 100 becomes the adapter 300 first at the rail 200 fixed on the front side. For this purpose, the subarea 305 of the first adapter section 303 in a back longitudinal recess 208 the rail 200 , which longitudinal recess 208 for example, in the manner of a shallow channel on one of the visible side S opposite side of the rail 200 is designed to be introduced. Using screws 322 is the subarea 305 of the first adapter section 303 in the longitudinal recess 208 the rail 200 clamped. See also 13 and 14 , The first adapter section 303 extends parallel to a longitudinal direction of the rail 200 ,

After fixing the adapter 300 at the rail 200 becomes the adapter 300 at the node element 100 attached. The annular area 145 of the first section 103 is opposite the edge 146 trained in depth. Part of the end area 304 of the first adapter section 303 extends into the area 145 into, such that by means of a screw 316 the adapter 300 with the first section 103 of the node element 100 can be screwed. Here is the convex surface 336 the axially projecting outer edge 146 facing inside and can rest against this, for example, while the concave surface 337 a substantially cylindrical central portion 155 of the first section 103 is facing. The screw 316 is through the through hole 315 passed through and into one of the holes 136 screwed.

The second adapter section 306 extends in that state in which it is the node element 100 with the rail 200 mechanically coupled, along an outside 109 of the node element 100 and close, see 9 , one the node element 100 facing end face 210 the rail 200 in essence, the front however in the area of the passage 310 of the second adapter section 306 remains open.

For the electrical coupling of the conductor device 215 with the conductor device 115 , and thus for the electrical connection of the rail 200 to the node element 100 , for both the operating voltage and for the switching and / or control signals is - after the described mechanical coupling by means of the adapter 300 - from the visible side S the connecting component 400 in the interior 203 the channel-like rail 200 inserted and partially through the passage 310 passed. As a result, the inserted connection component extends 400 in sections in the gap 110 of the node element 100 into, such that the first contact device 403 in the gap 110 with the conductor device 115 got in contact. In this case, contact the contact elements 421 each one of the tracks 116 while the contact elements 422 each one of the tracks 117 to contact. In addition, when inserting the connection component 400 in the rail 200 the connection component 400 by means of the locking devices 431 with the rail 200 locked, for example, in such a way that the locking devices 431 a longitudinal rib 204 , Longitudinal groove or longitudinal edge, see 14 , the rail 200 in their interior 203 engage behind. In addition, in the insertion process, the tongue-shaped locking device 460 behind an upper edge of the passage 310 engage, see, for. B. 12 , whereby the connecting component 400 in a direction radial to the node element 100 additionally held in position. The latching behind the upper edge of the passage 310 through the further locking device 460 is at a removal of the connecting member 400 again detachable.

When inserting and locking the connection component 400 further reaches the second contact device 406 with the conductor device 215 the rail 200 in electrical contact, such that the contact elements 428 one each of the ladder 216 and the contact elements 429 one each of the ladder 217 to contact.

Thus it can be seen that by means of the contact elements 422 and 421 the first contact device 403 electric current for the operation of the lighting devices 500 and one or more switching and / or control signals from the tracks 117 . 116 tapped and mediated via the contact elements 428 and 429 the second contact device 406 in the ladder 216 or. 217 the rail 200 be fed. On a connecting element 102 Alternatively, the electrical operating current and the switching and / or control signal from the conductors 216 . 217 the rail 200 tapped and in that as the connecting element 102 trained knot element 100 are fed through the electrical current and the switching and / or control signal then to other rails 200 is redistributed.

The connection component 400 is thus set up such that the switching and / or control signal from the conductor tracks 116 over the contact elements 421 tapped, to the contact elements 429 forwarded and by means of this in the ladder 217 can be fed. The forwarding of the switching and / or control signal is also possible in the reverse direction.

Furthermore, the connection component 400 set up such that the electric current for the operation of the lighting devices 500 from the tracks 117 over the contact elements 422 tapped, to the contact elements 428 forwarded and by means of this in the ladder 216 can be fed, with a forwarding of the electric current in the opposite direction is also possible.

By means of the ladder 117 of the node element 100 thus becomes a coupling of the node element 100 connected rails 200 in terms of the electric current for the operation of the lighting devices 500 allows while the ladder 116 the connected rails 200 couple with respect to the switching and / or control signal.

The combination of contact devices 403 . 406 on opposite sides 410 . 145 of the connection component 400 with the conductor device 115 of the node element 100 at its lower section 106 and the conductor device 215 at the bottom 206 the rail 200 contributes advantageously to the production of a reliable contact when inserting the connecting member 400 at.

The passage 310 of the second adapter section 304 is the cross-sectional shape of the connecting member 400 taking into account the contact elements 421 . 422 formed corresponding, such that the connecting member 400 with the end area 402 the same, in which the first contact device 403 is ahead through the passage 310 can be performed. One in the inserted state to the interior of the node element 100 directed face 455 of the connection component 400 is concave.

The node element 100 is, see, for example 3 and 9 , with one in the area of the central axis 119 arranged mounting device 131 equipped, which in the example shown a rope 132 or with the rope 132 is connectable. That way, how can you 1 described, the node element 100 mediates over the rope 132 at the building 600 , for example by hanging, be attached. Alternatively, in non-illustrated examples, the mounting device 131 for direct mounting of the node element 100 on the building 600 be educated. A suspended attachment may also add to the flexibility of the lighting assembly 1 , for example in the case of a conversion, contribute.

2 shows exemplary ways of connecting four rails 200 to a node element 100 as described above. In 2 are exemplary three rails 200a . 200b and 200c such with the node element 100 coupled that between the rails 200a and 200b as well as the rails 200b and 200c in each case an angular offset of 90 degrees about the central axis 119 is present. For the fourth track 200d are in 2 three exemplary angular positions with respect to the node element 100 drawn, the rail 200d either also at a 90 degree angle with respect to the rails 200a or. 200c can be arranged, or offset for example at an angle of 60 degrees relative to the rail 200a , or alternatively offset at an angle of 60 degrees with respect to the rail 200c , It should be noted that in the example shown, the fastening devices 136 of the first section 103 the connection of a total of up to six rails 200 at the node element 100 allow between two coupled adjacent rails in this example, an angular offset of at least 60 degrees is provided. With six coupled rails 200 the angular offset is then uniformly 60 degrees between adjacent rails 200 , In variants, it would be possible to provide other than the aforementioned angular offsets.

11 shows in a side view, as in the situation of 9 the connection component 400 in sections through the passage 310 passes, around in the gap 110 the contact with the conductor device 115 of the node element 100 manufacture. For the sake of clarity, in the view of 11 the rail 200 omitted.

The middle section of the 12 shows the situation of 11 again, again without representation of the rail 200 , By way of example, it will be apparent how the contact elements 422 the contact with the ladders 117 the conductor device 115 on the circuit board 114 produce. Further shows 12 that in an interior 166 of the second section 106 of the node element 100 which is in the in 12 shown case as a supply element 101 is formed, electrical and / or electronic components 178 are arranged, the provision of electrical power for the operation of the lighting equipment 500 and / or the switching and / or control signal serve. The interior 166 of the second section 106 becomes the visible side S towards by a lid, for example, fastened by a snap connection 164 locked.

In the 14 exemplary rail shown in cross section 200 is, as already mentioned, channel-like, and has an interior area 203 on, to the visible side S open, the lighting equipment 500 in whole or in part, and by side walls 207 as well as the channel bottom 206 is limited. On the insides of the two side walls 207 are each one of the longitudinal ribs 204 educated. From the interior 203 are accessible from the area of the ground 206 the rail 200 the ladder 216 and 217 the conductor device 215 arranged. To provide the ladder 217 For example, a tape in the rail 200 be introduced, by means of the same the ladder 217 in the rail 200 are attached. In this way, in such an example, the conductors form 217 Components of the conductor device 215 ,

On one of the interior 203 opposite side of the ground 206 shows the rail 200 the longitudinal recess 208 which has the shape of a shallow channel. In the area of the lateral boundaries of the longitudinal recess 208 is the rail 200 with undercuts 209 formed behind each one on the first adapter section 303 , in the area of the subarea 305 , formed on both longitudinal sides of the same step 323 can intervene. Will, as in 9 shown, the first adapter section 303 with the subarea 305 in the longitudinal recess 208 pushed in, get the steps 323 behind the undercuts 209 , By tightening the screws 322 then it succeeds, the adapter 300 with the rail 200 to jam and a reliable attachment of the adapter 300 at the rail 200 sure. This is also in 13 clarified. After attaching the adapter 300 at the node element 100 by means of one of the fastening devices 136 can then be the insertion of the connecting component 400 respectively.

A kit for use in the construction of the lighting arrangement 1 According to the embodiment described above comprises at least one node element 100 which acts as a connecting element 102 or as a supply element 101 may be formed, at least one adapter 300 and at least one connecting component 400 , The kit can also use the screws 316 . 322 include. It is understood that a kit also has several node elements 100 used as supply and / or connection elements 101 . 102 may be formed, as well as a plurality of adapters 300 and connecting components 400 may include. In addition come in the construction of the lighting arrangement 1 especially the rails 200 and the lighting devices 500 for use.

It should be noted that the first and second sections 103 . 106 of the node element 100 may be formed in an exemplary variant with a prismatic outer shape, for example, with a hexagonal base. In such a variant, for example, six fastening devices 136 at regular intervals of 60 degrees around the central axis 119 be arranged around.
