Description

FIELD OF THE INVENTION

The invention relates to the field of lighting devices. The invention further relates to a connector for forming a lighting device, by means of which at least two lights can be coupled.

TECHNICAL BACKGROUND

In DE 20 2016 004 265 U1 For example, connecting two lights is described.

Furthermore, it describes DE 10 2013 226 950 A1 a profile lighting system, wherein an electrical and load-bearing connection of two linearly arranged profile lights in a row is described using a connecting plug.

It would be desirable to be able to assemble a variety of lighting solutions flexibly, mechanically stable and easily, preferably without complex, time-consuming cabling on a construction site, and preferably to be able to align lights of the lighting device created in this way at least during and/or after assembly.

SUMMARY OF THE INVENTION

Against this background, the invention is based on the object of specifying an improved lighting device that enables an uncomplicated, quick and flexible implementation of a variety of lighting solutions. Furthermore, a correspondingly improved connector for a lighting device is to be specified.

According to the invention, this object is achieved by a device with the features of claim 1 and / or by a connector with the features of claim 15.

Accordingly, a lighting device is proposed, comprising a first lamp, which is formed at least at a first front end thereof with a lamp-side connection region, and at least one connector which is set up for coupling the first lamp to at least one second lamp of the lighting device. Here, the connector is designed for a detachable connection of the first lamp and the second lamp to the connector. A connector side The connection region of the connector is designed to interact with the lamp-side connection region of the first lamp for the detachable mechanical connection of the first lamp to the connector. Furthermore, the connector-side connection region of the connector is designed or configured or configurable for cooperation with the lamp-side connection region of the first lamp for releasably electrically connecting the first lamp to the connector. A component group comprising the connector and the first lamp connected to it is set up to allow the first lamp to be rotated about a longitudinal axis of the first lamp relative to a base part of the connector. In particular, an emission direction of the first lamp can be changed relative to the base part by rotating it.

Furthermore, the invention creates a connector for the formation of a lighting device, having at least two connector-side connection areas, wherein by means of the connector at least two lights, in particular at least two elongated lights, can be coupled to one another in such a way that the lights in a state connected to the connector are each about their Longitudinal axis can be rotated relative to one another, and in particular independently of one another, and wherein the connector-side connection areas are each configured or configurable in such a way that the connector-side connection areas each provide a detachable mechanical and electrical connection of one of the lights to the connector in the area of at least one front end of the light make possible.

One idea underlying the invention is to combine a simple possibility of coupling the lamp in the area of the end face of the same with the connector with the possibility of rotation. The rotatability can still be present when it has been fully assembled on a building, for example, for subsequent alignment of the lamp(s), or the rotatability can be used during assembly to give the lighting device the desired shape, which can then be secured by fastening it the lighting device is fixed. Combinations are also possible within a lighting device.

It is therefore possible to create diverse, flat or spatial lighting devices in a highly flexible, modular and simple manner, which also enable the lights to be aligned during and/or after installation by means of twisting.

The invention advantageously offers in particular the possibility of coupling lights to one another in a simple manner mechanically, in particular mechanically and electrically, via the connector and thus being able to easily create a group of lights without a complicated, cumbersome cabling effort is necessary on a construction site. At the same time, lighting devices can be designed flexibly.

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

In particular, a mechanical or a mechanical and electrical coupling of the first lamp to the at least one second lamp of the lighting device can be effected by means of the connector. For example, lighting devices can be created in this way in which a large number of lights are mechanically or mechanically and electrically coupled to one another, directly or indirectly, by means of the connectors, whereby the electrical coupling can be specifically prevented at some connection points between the light and connector, for example to form different electrical circuits and/or avoid a ring-like closed circuit.

In one embodiment, the component group is set up to allow the first lamp to be rotated in the state connected to the connector relative to the base part of the connector about a longitudinal direction of the first lamp, which corresponds to its longitudinal axis.

In particular, the direction of emission of the first lamp can be changed by rotating it in order to be able to illuminate either a ceiling or a wall or a desired location in a room, depending on the spatial arrangement of the first lamp. This creates a variety of possibilities for designing the shape of the lighting device and for producing lighting effects.

In one embodiment, the component group further comprises the second lamp connected to the connector and is capable of rotating the second lamp about a longitudinal axis of the second lamp, which preferably corresponds to a longitudinal extension direction of the second lamp, relative to and independently of the first lamp, and in particular relatively to the base part of the connector. In particular, an emission direction of the second lamp can be changed by means of twisting, for example in order to be able to illuminate either a ceiling or a wall or a desired location in a room, depending on the spatial arrangement of the second lamp. This advantageously creates further possibilities for flexible, diverse alignment and arrangement of the lights within the spatial shape of the lighting device.

In one embodiment, the connector-side connection area is designed or configured for interaction with the luminaire-side connection area at least at the first front end of the first luminaire for an electrical connection at mains voltage, in particular at a nominal voltage in a range from approximately 100 volts to approximately 240 volts or configurable.

Furthermore, in one embodiment, the connector-side connection area can be designed or configured or configurable for interaction with the luminaire-side connection area at least at the first front end of the first luminaire for an electrical connection for forwarding control signals, such as DALI signals.

In one embodiment, the electrical connection can be multi-pole, in particular five-pole, by means of the interacting connector-side and luminaire-side connection areas, and can, for example, contain a coupling of conductors of a multi-pole, in particular five-pole, line.

In one embodiment, the connector is designed to provide an external supply of at least the first lamp with an electrical input current, in particular alternating current at mains voltage, for example at a nominal voltage in a range from approximately 100 volts to approximately 240 volts, via the interacting connector-side and luminaire-side connection areas, and/or with a control signal, for example a DALI signal. The connector can therefore be used advantageously for electrical supply and connection to a source of control signals.

In one embodiment it is provided that the first lamp is designed at a second front end thereof for an electrical coupling with electrical conductors, in particular for the transmission of electrical current, for example alternating current, at mains voltage, for example at a nominal voltage in a range of approximately 100 Volts to approximately 240 volts, and/or for transmitting a control signal, for example a DALI signal, and/or that the first luminaire is formed at a second front end with a further luminaire-side connection area. This contributes to increased flexibility and diverse design options.

In one embodiment, the first lamp is mechanically or mechanically and electrically connected to an end cover at the second front end thereof. The second front end can therefore be electrically and aesthetically cleanly terminated.

In another embodiment, the first lamp is releasably mechanically and electrically connected at the second front end thereof to a second connector, by means of which the first lamp can be coupled to at least a third lamp. In this way, larger lighting devices in a variety of shapes are possible, for example for illuminating larger areas of space.

In one embodiment, the end cover or the second connector is equipped with a supply device for supplying at least the first lamp with the input current and/or the control signal. This creates additional options for supplying power or control signals. The supply of the lighting device can therefore be easily achieved, particularly in the case of larger lighting devices with multiple ends and many connectors, by making a suitable selection at a suitable location, and several sections of the lighting device can also be supplied independently if necessary.

In one embodiment, the first lamp has an LED device, in particular a circuit board provided with LEDs, for providing light to be emitted by the first lamp during operation and an operating device for supplying the LED device. Here, the operating device is designed to convert an input current and/or designed to interpret a control signal and to control the LED device depending on the control signal. This creates elegant, energy-saving, versatile lighting.

In one embodiment, the connector is designed with at least one further connector-side connection region, which is set up for the interaction of the further connector-side connection region with a lamp-side connection region of the second lamp, which is provided at a front end thereof, for the detachable mechanical connection of the connector to the second lamp and is set up or configured or configurable for interaction of the further connector-side connection region with the lamp-side connection region of the second lamp for the detachable electrical connection of the connector to the second lamp. The connection areas on the connector side are preferably designed in the same way. This results in even greater flexibility and variety with regard to the structure and supply of the lighting device.

In particular, the connector-side connection areas of the connector are electrically coupled to one another in such a way that lights electrically connected to these connection areas are electrically coupled via the connector. This is the electrical one Coupling of the connector-side connection areas is preferably provided within the connector, for example by means of flexible lines.

In one embodiment, the connector-side connection regions are formed on the connector in such a way that longitudinal extension directions of the first and at least the second lights releasably connected to the connector are different from one another, in particular enclose a non-zero angle with one another, for example are arranged essentially at right angles to one another, or that longitudinal extension directions the first and second lights releasably connected to the connector are parallel or the same. This enables a diverse structure of the lighting device.

In further embodiments in which the connector has more than two connector-side connection areas, these can be provided such that the longitudinal extension directions of all lights connected to the connector are different from one another, for example are arranged at right angles to one another, or that at least a pair of two lights connected to the connector Lights have longitudinal extension directions that are parallel or correspond to each other.

In one embodiment it is provided that the connector-side connection region for mechanical connection is designed in sections for insertion into the first lamp, in particular parallel to the longitudinal axis of the first lamp, and/or the further connector-side connection region for mechanical connection is in sections for insertion into the second lamp, in particular parallel to the longitudinal axis of the second lamp, and / or that the connector-side connection area or the first lamp is equipped with a ball pressure device and / or with a screw device for fixing the mechanical connection of the connector to the first lamp and preferably further connector-side connection area or the second lamp is equipped with a ball pressure device and / or a screw device for fixing the mechanical connection of the connector to the second lamp. Pushing in allows for a simple mechanical connection. With the help of the ball pressure device, an automatic fixation of the connection during assembly can be achieved, in particular without the use of tools, which requires little time and effort and is particularly useful under limited loads, for example to secure the connection against horizontal movements. An alternative or additional fixation by means of the screwing device, for example by screwing a clamping screw into it, enables further fixation that withstands higher loads, for example to secure the connection against vertical loads from weight forces.

In embodiments, the ball pressure device and/or the screwing device for fixing the mechanical connection of the connector to the first lamp or the second lamp can each preferably be provided on the connector-side connection region or on the lamp-side connection region of the first or second lamp.

In a further development, at least the connector-side connection area of the connector and the lamp-side connection area of the first lamp can be mechanically connected by plugging them together, with configuration being possible in such a way that when plugging together, an electrical connection of the first lamp to the connector can be brought about at the same time or the There is no electrical connection. In this way, for example, the electrical coupling can be prevented at one or more desired connection points of the lamp and connector, at which the lamp and the connector can be held together, in particular mechanically, in order to prevent a ring-like closing of the circuit or in order to to divide the lighting device into several separately powered and/or controllable sections. When setting up the lighting device, a fitter is offered a high degree of flexibility with regard to the shape and supply of the same; the fitter can adapt the connection area(s) on the connector side as required by configuring them.

In one embodiment, at least the lamp-side connection region formed on the first front end of the first lamp is formed with a first component of an electrical plug connection, in particular a plug-like component, and in the connector-side connection region, preferably in each of the connector-side connection regions, a second component corresponding to the first component Component of the electrical plug connection, in particular a socket-like component, provided or attached or attachable. With the help of the plug connection, the electrical connection is easy to establish during assembly and easy to remove again for disassembly.

In particular, the electrical plug connection of the first lamp can be plugged together with the connector along a longitudinal direction of the first lamp.

In further embodiments, the lamp-side connection region of the second lamp is designed in the same way as the lamp-side connection region of the first lamp with a first component of an electrical plug connection, in particular the electrical plug connection of the second lamp being able to be plugged together with the connector along a longitudinal extension direction of the second lamp. An analog design can be provided for additional lights that can be connected to the connector. The first, second and further lamps can/can in particular be formed at their two front ends with a lamp-side connection region with the first component of an electrical plug-in connection in the same way and as described above with regard to the first lamp, or the first component of the plug-in connection can only be provided at one front end.

In a further development, the connector is designed or configured or configurable in such a way that the first lamp and the connector can be electrically connected to one another without tools and, in particular, can be detached from one another again. An analogous embodiment can be provided with regard to the connection of the second light and connector.

Furthermore, the first lamp and the connector can, for example, be mechanically connected to one another without tools and/or with the aid of a tool and, in particular, can be detached from one another again. This allows for easy creation of the connection. The tool can be used in particular in the case of higher loads due to weight forces, for example in the case of a substantially vertical connection of a lamp to the connector. An analogous embodiment can be provided with regard to the connection of the second light and connector.

In one embodiment, the first lamp and/or the connector and/or the end cover has/have a device for fastening the lighting device by hanging it, in particular by means of a rope, and/or for fastening the lighting device by ceiling mounting or ceiling structure and/or for fastening the Lighting device by mounting on a wall. This allows the lighting device to be used in a variety of ways.

In one embodiment, the connector has at least one connection part mounted on the base part so that it can rotate about an axis, the connector-side connection region being formed on the connection part. This configuration can be applied to the several connection areas on the connector side and contributes to a stable, rotatable connection. The connecting part can be mounted so that it can be rotated continuously around the axis or the mounting can enable haptic detection of defined angles of rotation.

In one embodiment, the connecting part has a bearing section, preferably with a substantially circular cylinder-like or circular hollow cylinder-like basic shape, with a radial and preferably ring-like projection running around the connecting part and the base part has a receiving area with an inner annular surface, wherein the projection can be received by the receiving area in such a way that the projection slides on the annular surface when the connecting part is rotated and is held in the axial direction on the base part by at least one axial shoulder delimiting the annular surface . In this way, a stable, rotatable mounting is made possible, which creates space in an interior area of the basic shape, for example for electrical connection purposes. In particular, the second component of the plug connection can be provided or fastened in sections in the interior of the basic shape. The plug connection is therefore well protected.

In one embodiment it is provided that the storage section of the connecting part is equipped with one or more ball pressure devices, with pressure being able to be exerted on the base part in the area of the annular surface by means of the ball pressure device(s), in particular in the radial direction. In particular, the annular surface can also be provided with recesses which enable one or more of the ball pressure devices to be releasably engaged in a plurality of predefined rotational positions of the connecting part. This makes it possible to ensure that the alignment of the lamp is not accidentally adjusted by slight contact, as turning the connecting part requires overcoming resistance. The desired lighting effect can thus be reliably ensured. Furthermore, the rotational position can be made haptically recognizable by means of the recesses, which contributes to the simple and precise alignment of the lamp.

In one embodiment, the connecting part has an insertion section which, in the connected state of the first lamp and the connector, extends essentially parallel to the longitudinal extension direction of the first lamp and is provided, for example, with a stepped cross-section, which is used to connect the connecting part to the first lamp in a, for example undercut, corresponding groove of a profile body of the first lamp can be inserted at the front. A corresponding embodiment can be provided with regard to the connection of the second lamp or further lamps to the connector. A reliable mechanical connection is thus achieved, in particular via an additional element that is independent of the electrical plug connection, but which can preferably be achieved simultaneously with the electrical connection when assembling the lighting device if the connection point in question is not configured for the electrical connection to be omitted .

In one embodiment, the lights are each elongated, in particular with an elongated cylindrical outer basic shape. Such a shape enables, for example, lighting devices with a strand-like, angled, branched and/or grid-like structure on the surface or in space in a variety of ways. In particular, the lights can be arranged and coupled to one another to form a mechanically circumferentially closed shape, such as a polygon-like shape.

The above configurations and further developments can be combined with one another in any way, provided this makes sense. Further possible refinements, further developments and implementations of the invention also include combinations of features of the invention described previously or below with regard to the exemplary embodiments that are not explicitly mentioned. In particular, the person skilled in the art will also add individual aspects as improvements or additions to the respective basic form of the present invention.

Furthermore, it is understood that the above refinements and developments can be applied in an analogous manner to the lighting device and the connector.

DESCRIPTION OF EMBODIMENTS

Fig. 1 schematically illustrates a modular system for lighting devices 100, 200, 300, 400, 500 with lights 1 and 2 of different types and different connectors 11, 12, 13 and 5. Other connector types explained below may be available. The lights 1, 2 are each designed to be elongated with a longitudinal extension direction L and can in particular each be designed with a cylindrical or cylindrical outer shape, for example with a circular cross section.

The lighting device, for example the complete arrangement 100, 200 or 300 Fig. 1 , can be suspended or mounted on a ceiling and/or on a wall or walls, in particular optionally with fastening devices which are attached to the connectors and/or to the individual lights 1, 2 and/or to end covers 4, 4' described in more detail below. , 6 are provided. Combinations of these fastening methods are conceivable.

Fig. 1 shows a lamp 1 of a first type and a lamp 2 of a second type. The lamp 1 is formed at one front end 1a thereof with a lamp-side connection region 31 of a first type and at its other front end 1b with a lamp-side connection region 32 of a second type. The light 2 is at their two front ends 2a, 2b each formed with a lamp-side connection region 31 of the first type.

Fig. 1 also shows schematically a first end cover 4 of a first type and a first end cover 4 'of a second type. The end covers 4, 4' are each for feeding input current and control signals, such as DALI signals, into one with the end cover 4 or 4' connected lamp 1, 2 set up. Furthermore, the system is Fig. 1 a second end cover 6 is provided without an electrical supply function, which is not shown in detail. The end cover 6 is designed to close the free ends of lights 1, 2 in an aesthetically and electrically clean manner and can be used, for example, in Fig. 1 , 2 shown. The end cover 6 closes the end face of the lamp 1, 2 that is not used for a connection and also offers electrical protection against contact with the connection area 31 or 32 on the lamp side.

Fig. 1 also shows a linear connector 5 for the detachable electrical and mechanical front-side coupling of several lights 1 of the first type one behind the other or of a light 1 with a light 2 of the second type.

Fig. 1 shows three exemplary node connectors for lights 1 and/or 2, a 2D node connector 11 of type L, a 2D node connector 12 of type T, and a 2D node connector 13 of type X. The node connectors 11, 12, 13 differ in terms of the number of lights 1, 2 that can be connected to the connector and the arrangement of connector-side connection areas 41 provided for this purpose. The node connector 11 has two, the node connector 12 three and the node connector 13 four similarly designed connection areas 41. The node connectors 11, 12, 13 are intended to be able to mechanically and electrically couple lights 1, 2 to one another. The electrical coupling is achieved via a circuit implemented in the connector 11, 12, 13 or internal electrical coupling of the connection areas 41 of the same connector 11, 12, 13.

With the system of Fig. 1 A configuration option described in more detail below is also provided, which allows an electrical connection to be created or prevented in the connection areas 41 with the coupled lamp 1 or 2.

Each of the lights 1 and 2 can cooperate with the connector 11, 12 or 13, or one of the further connectors described below, at any of the connection areas 41, 41 ' be mechanically releasably connected to one of the connection areas 31 in the same way. A detachable electrical and mechanical connection is possible by means of the connection areas 31 in cooperation with a connection area 41.

Each of the lamp-side connection areas 31 is similar and has a first, plug-like component 62, in Fig. 1 marked with “x”, trained. Each of the connector-side connection areas 41 is also designed in the same way and can be configured in the same way. In each of the connection areas 41 there is a second, socket-like component 61, in Fig. 1 marked with "o", can be fastened in such a way that the components 61 and 62 can work together as a multi-pole, for example five-pole, electrical plug connection 60. Within each of the node connectors, such as connectors 11, 12 or 13, the components 61 are coupled in such a way, in other words, their poles are switched or electrically connected in such a way that current and control signals that are present at a socket 61 are sent to the socket(s) 61 of the other connection area(s) 41 of this connector.

The plug connection 60 of plug "x" and socket "o" can be plugged together by pushing them together along the longitudinal direction L of the lamp 1, 2 to be coupled, if the connection area 41 is configured by arranging the associated component 61 in a position of use for establishing the electrical connection .

The lights 1, 2 of the first and second types are in particular not only designed to be operated and controlled with the operating current received via one of the end connection areas 31, 32 and the control signals received there for the emission of light, but are also designed to Operating current, for example at mains voltage, approximately 230 V, and the control signals, from one front connection area 31, 32 to the other front connection area 31, 32, in order to make contact and electrical coupling with other connectors and lights 1, 2 to enable. Control signals and operating current can be provided within the device in one or more circuits indirectly via the electrical coupling starting from the feed point(s) to the coupled lights 1, 2.

The connector-side connection area 41 can also be configured in such a way that there is no electrical connection and thus only a mechanical connection is established at this connection point, but no electrical plug connection no transmission of operating current and/or control signals is achieved. Connector-side connection areas configured in this way are identified by reference number 41' and a filled circle.

The lighting device shown as an example 100 in Fig. 1 is designed as a linear strand of several individual lights 1 coupled to one another, with the supply of operating current and control signals at one end of the strand via the end cover 4. The end cover 4 has a socket-like component, designated "o", which is connected in the same way as the components 61, "o", the connector 11, 12, 13 with the plug 62, "x" of one of the lights 1 or 2 can be plugged together. At the other end of the strand of the device 100 there is an electrically blind end cover 6. However, the arrangement could instead be reversed, in which case the current and the control signals are fed in via an end cover 4 ', which has a plug-like component 62, "x". , and the plug "x" is plugged into the free socket "o" of the lamp 1 located at the other end of the strand.

The lights 1 are connected to each other by the linear connectors 5, which have a plug on one side like component 62 ("x") and on the opposite side a plug like component 61 ("o"), which means that the sequence of the Luminaires 1 with linear connectors 5 in between as is possible with device 100.

In the lighting device 200 according to an exemplary embodiment of the invention, an additional lamp 2 of the second type and a node connector 13 of type . Thus shows Fig. 1 only part of the lighting device 200.

A larger lighting device 300 according to a further exemplary embodiment, which also extends in the plane of the drawing, is shown in FIG Fig. 1 with several branches and a mechanically closed square ring. On the connector 13 of the device 300 is the in Fig. 1 downward-pointing connection area 41 ', • configured in such a way that the electrical plug connection is omitted there and in the square circumferential part Fig. 1 bottom right, a ring-like closure of the circuit is prevented. Another connection area 41′ configured in this way is shown for the connector 12 of the device 300.

In contrast to the linear connector 5, the node connectors 11, 12, 13 and node connectors of other types described below are designed in such a way that after the electrical and mechanical or, in the case of the correspondingly configured connection area 41 ', the purely mechanical connection of the lights 1 and 2 to the Connector, the lamp 1, 2 on the connector and relative to one or more other lamps 1, 2 connected to the connector can be rotated about the longitudinal direction L, which forms a longitudinal axis A of the lamp. In the present exemplary embodiments, the lamp 1, 2 can be rotated about the axis A within a limited angular range, the angular range being in particular smaller than 360 degrees, for example having a size in a range of approximately 300 to approximately 350 degrees. Thus, the lamp 1 or 2 on the connector 11, 12, 13 can be rotated, for example, by +/- 150 degrees or by +/- 170 degrees or by +/- 175 degrees.

It should be mentioned that in the case of the connection area 41 'configured for the absence of the electrical plug connection, a mechanical connection is also possible with the lamp-side connection area 32 of the second type.

Fig. 1 illustrates a kit that enables the construction of a variety of lighting devices and in particular enables lights 1, 2 to be electrically and mechanically connected along two axes in the plane or along all three axes in space.

The plug connection 60 in the connection areas 31, 32, 41 of the lights 1, 2 and the node connectors 11, 12, 13 as well as on the end cover 4, 4 'and linear connector 5 is designed to provide an electrical connection to the power supply with alternating current, for. B. at mains voltage, in particular at a nominal voltage in the range of about 100 volts to about 240 volts, about 230 V. In addition, for example, two of the five available poles can be used for a DALI signal, or for a signal based on another suitable protocol. The external supply via the end covers 4, 4 'also takes place with alternating current, for example. B. at mains voltage, for example at a nominal voltage of around 100 volts to around 240 volts, e.g. 230 V.

The lights 1, 2 can alternatively be supplied with operating current and control signals via one of the connectors 11, 12, 13. The modular system includes variants of the connectors with a feeder 77, in particular with a feed opening 78, in order to be able to guide a five-pole, cable-shaped supply line, for example, into the connector. Variants 12 ', 13' of the connectors 12 and 13 with feed opening 78 and feed device 77 are in Fig. 4 , 9-15 , 19 shown. Operating current and control signals are sent to the lights via the interacting connection areas 31, 32, 41 1, 2 forwarded. In a modular system, not all types of node connectors are necessarily provided in a variant with a feed device 77; for example, variant 13' could be dispensed with. The end covers 4, 4' can each have an analogous feed device 77.

Fig. 1 further shows for the device 300 that by preventing the electrical plug connection by appropriately configuring the connection area 41 ', for example in the device 300 at two locations, separate power and control circuits can be achieved, which are in Fig. 1 are fed via an end cover 4. The components of the device 300 are mechanically connected to one another as a whole.

Fig. 2, 3 show further lighting devices 400, 500, each of which is spatially designed with branches and a partially grid-like structure.

In the device 400, a connector 21 is provided, which is designed as a 3D node connector of type L with additional downward coupling and has four of the connector-side connection areas 41. The supply of operating current and control signals takes place in Fig. 2 by means of an end cover 4. At the connector-side connection area 41 'of the connector 12, the electrical connection and thus a ring-like closed circuit is prevented. As an alternative to the supply via the end piece 4, one of the connectors 11, 12, 21 can, in one variant, provide an external supply of the lights 1, 2 of the device 400 with alternating current at mains voltage, for example at approximately 100 V to 240 V, and for example with a DALI Signal, enable.

In the device 500, a three-dimensional structure is realized with the help of a twist on one of the 2D connectors 11 of type L, whereby an obliquely rising branch is created on the in Fig. 3 side of the device 500 shown at the back is realized. Device 500 can be supplied, for example, via the connector 13′ and the end cover 4, with alternative supply variants being possible, for example via other connectors.

While the node connectors 11, 12, 12', 13, 13', 21 enable the lights 1 and/or 2 coupled to them to be rotated in different combinations independently of one another on the connector, the linear connector 5 rigidly couples two lights 1, 2 with each other, whereby the lights coupled by means of the linear connector 5 can be the same or different, for example two lights 1 of the first type or a light 1 of the first type and a light 2 of the second type. Different combinations are possible. However, a coupling of two lights 2 of the second type is not produced by means of a linear connector 5; instead, a light 1 of the first type can be used on one side of the connector 5, as in device 300 in the lower branch on the left.

Fig. 5 shows one end of a lamp 1 or 2, with a front lamp-side connecting section 31 with the plug-like component 62 being shown. The lamp 1, 2 has an elongated profile body 91, an optical element 93 and a translucent cover 94. The optical element 93 is in the exemplary embodiments Fig. 4-20 designed, for example, as a lens, with the optical element 93 also being designed as a reflector, for example.

The profile body 91, the optical element 93 and the cover 94 each have a constant cross section along the longitudinal extent L of the lamp 1, 2. For example, the profile body 91 can be extruded, for example from a metal material, and the optical element 93 designed as a lens and the cover 94 can be extruded, for example each from a plastic material. The optical element 93 is connected to the profile body 91 by means of engagement geometries arranged on both longitudinal sides, which engage in assigned engagement geometries of the profile body 91. The cover 94 is connected to the body 91 by means of engagement geometries arranged on both long sides thereof, which engage in further, assigned engagement geometries of the profile body 91. An outside of the cover 94, together with an outside of the body 91, essentially forms a cylindrical shape with a circular cross section, with the exception of a T-like undercut groove 92 in the body 91. The optical element 93 with an LED device 50 arranged thereon, which is designed as an elongated Circuit board is formed with LEDs, is accommodated in an interior formed by the profile body 91 and the cover 94 in their interaction.

By means of the LED device 50, the light to be emitted by the lamp 1, 2 is provided and directed and/or bundled by the optical element 93. To supply the LED device 50, each of the lights 1, 2 has an operating device 55, see Fig. 6 , which is flat and elongated and is accommodated in an interior region formed by the element 93 and the profile body 91 between the optical element 93 and the body 91. The operating device 50 is designed to convert an input current supplied via one of the connection areas 31 or 32, and is preferably set up to interpret the control signal provided to the lamp 1, 2 via the area 31 or 32 and the LED device 50 depending on this to control. The body 91, the optical element 93 and the cover 94 end essentially flush with one another at the ends of the lamp 1, 2. A holding insert 65 for one of the components 62 or 61 of the plug connection 60 is inserted into each end of the lamp 1, 2 at the front and fixed to the profile body 91 by means of screws. A section of the mounting insert 65 partially covers the area of the lamp 1, 2 provided with electrical devices between the body 91 and the element 93 on the front side.

The mounting insert 65 has a rectangular through opening 66, which is surrounded by the mounting insert 65, for example in a frame-like manner, and is designed to provide access to the plug-like component 62 from the outside, see Fig. 5 , or the socket-like component 61, see also Fig. 10 . For example, lamp 2 is of the second type, see Fig. 7-8 , an insert 65 and a plug 62 are provided at both ends; in the lamp 1 of the first type, one of the plugs 62 is replaced by the socket 61. Each of the components 61, 62 has lateral locking geometries 67a, which can be locked with assigned locking geometries 67b of the holder insert 65. Plug 62 and socket 61 are essentially accommodated within the lamp 1, 2 when assembled and are accessible through the opening 66.

The connection areas 41 are arranged in the connector 11 in such a way that the longitudinal extension directions L of lights 1 and/or 2 connected thereto form an angle of 90 degrees with one another. In the case of the connector 12, 12 'with a T-like design, the longitudinal extension directions L of two lamps 1 and / or 2 connected to it coincide, the longitudinal extension direction L of the third lamp 1 or 2 is perpendicular to that of the first two lamps, see in Fig. 9 the angle θ = 90 degrees. In the connector 13, 13 ', the connection areas 41 are arranged in such a way that the lights 1, 2 are coupled in a cross shape, i.e. the longitudinal extension directions L of oppositely coupled lights 1, 2 coincide in pairs, the longitudinal extension directions L of adjacent lights 1, 2 form an angle of 90 degrees to each other. The connector 21 in turn is suitable for coupling lights in the manner of a spatial corner. The lights 1 and 2 connected to the connector 21 at the three connection areas 41 have longitudinal extension directions L, which are perpendicular to one another in pairs and point in all three spatial directions.

Other possible node connectors may have additional connector-side connection areas 41, which are designed and configurable in the same way as described herein. In particular, for example, a spatial or 3D connector not shown in the figures of type T can be provided, which is supplemented with respect to the 2D-T connector 12 by a connection area 41, which has a lamp 1, 2 additionally connected to this connector with a longitudinal extension L perpendicular to the plane of the other three longitudinal extensions L, corresponding to the plane of the drawing in Fig. 1 , enabled. In addition, a further 3D connector can be provided, which is supplemented by a connection area 41 with respect to the 2D-X connector 13, which enables a lamp 1, 2 additionally connected to this connector with a longitudinal extension L perpendicular to the plane of the other four longitudinal extensions L . Furthermore, a connector is conceivable in which, based on the configuration of the connector 13 Fig. 1 one connection area 41 each points up and down relative to the plane of the drawing, which means that two lights 1, 2 with longitudinal extension directions L perpendicular to the plane of the drawing Fig. 1 can also be coupled. Such a connector would therefore be of the “3D star” type.

In particular, for each of the 2D connector types 11, 12, 13, three additional 3D connector types with additional connection areas 41, directed upwards, downwards or upwards and downwards, can be created. The “top” can be the one with the fastening device, e.g. B. for hanging, provided side of the connector.

Going beyond the above, connectors are conceivable in which connection areas 41 are arranged in such a way that longitudinal extension directions L of coupled lights 1, 2 enclose angles other than 90 degrees with one another.

Connecting each of the lights 1 or 2 to one of the node connectors, such as one of the connectors 11, 12, 12 ', 13, 13', 21, is done in a simple manner by plugging the light with its connection area 31 along the direction L of the light 1 , 2 on the connection area 41.

Each connection area 41 can be configured in two ways. In a first configuration, here designated 41 and "o", when the area 31 is plugged onto the area 41, the mechanical and the multi-pole electrical connection are established at the same time. In a second configuration, here designated 41' and "•", when the area 31 is plugged onto the area 41, the mechanical connection is established, but an electrical connection does not occur.

The connector 11, 12, 12 ', 13, 13', 21 as well as each of the other node connectors described above is equipped with connection parts 80, the connection part 80 being a separate one Part is rotatable relative to a housing-like, hollow base part 11b, 12b, 12b ', 13b, 13b', 21b of the connector 11, 12, 12', 13, 13', 21. Here, the connecting part 80 is rotatably mounted on the base part 11b, 12b, 12b', 13b, 13b', 21b about an axis A'. Each connection area 41 is formed on such an associated connection part 80.

The finished base part 11b, 12b, 12b', 13b, 13b' and 21b is each formed with interconnected shell parts 11s, 11t, 12s, 12t, 12s', 12t', 13s, 13t, 13s', 13t' or 21s, 21t .

When the lamp 1, 2 is connected, its longitudinal axis A coincides with the axis A 'of the associated connecting part 80 in the exemplary embodiments. The connecting part 80 each has an insertion section 90, which is designed as a projection projecting parallel to the axis A 'of the connector 11, 12, 12', 13, 13' or 21 and has a stepped cross-sectional shape that is similar to that of the undercut groove 92 corresponds. The section 90 can thus be inserted from the front end 1a-b, 2a-b of the lamp 1, 2 into the groove 92 in order to establish the mechanical connection between the lamp 1, 2 and the connecting part 80.

A ball pressure device 45 is provided on the insertion section 90 to fix the mechanical connection of the lamp 1, 2 with the connector 11, 12, 12 ', 13, 13' or 21, which has a spring-loaded ball and a pressure in the direction of the bottom of the groove 92 can exercise. In this way, the creation of the mechanical connection requires a certain amount of hand strength and is fixed against movements and moderate forces. A recess 92a is provided at a point in the bottom of the groove 92 near each of the front ends 1a-b, 2a-b of the lights 1, 2, where the ball pressure device 45 comes to rest in the fully collapsed state. The recess 92a can, for example, be designed as a hole, for example as a through hole through the groove base, or instead as a non-continuous recess. The ball of the ball pressure device 45 can snap into the recess 92a to further improve the mechanical fixation.

In addition, a screwing device 46 is provided on the insertion section 90, which is designed as a threaded hole extending through the section 90. A clamping screw can be screwed into the threaded hole 46 in order to achieve even better fixation and to secure the mechanical connection against weight forces, for example. This can e.g. B. be useful if, due to the spatial shape and / or arrangement of the lighting device, the longitudinal extension L and groove 92 run vertically. Although the above-described arrangement of the devices 45, 46 is preferred, it is understood that in variants the arrangement of the devices 45, 46 and the recess 92a may be different and one or both of the devices 45, 46 on the profile body 91 and in the case of Device 45 on the body 91, the recess 92a could be formed on the insertion section 90.

Thus, the lights 1, 2 can each be connected mechanically in the connection area 41 to the node connector without tools, with an additional mechanical fixation being achieved by means of the clamping screw with a tool, for example a screwdriver or Allen key.

The electrical connection in the interaction of the connection area 31 with the connection area 41 takes place without tools by plugging the plug 62 and socket 61 together during mechanical assembly.

The connecting part 80 has a storage section 81 with a basic shape similar to a hollow cylinder. The storage section 81 is arranged on a first side of the connecting part 80. A radially outwardly facing outer surface of the connecting part 80 forms part of a circular cylindrical surface which corresponds to the outer surface of the lights 1, 2 and enables a clean transition. On a second side of the part 80 opposite the first side, the insertion section 90 extends from an edge region thereof parallel to the axis of rotation A '.

The storage section 81 is formed with a radial projection 82 that runs around the connecting part 80 in a ring-like manner. The base part 11b, 12b, 12b', 13b, 13b', 21b is provided with a receiving area 86 with an inner annular surface 87. The receiving area 86 accommodates the projection 82 in a rotatable manner, with the projection 82 sliding on the annular surface 87 when the connecting part 80 is rotated. By constructing the base part 11b, 12b, 12b', 13b, 13b', 21b with the assembled shell parts 11s, 11t, 12s, 12t, 12s', 12t', 13s, 13t, 13s', 13t' or 21s, 21t and a dividing plane that runs through the rotation and central axis A 'of the connecting part 80 and the projection 82, the connector 11, 12, 12', 13, 13', 21 can be assembled in a simple manner. Axial circumferential shoulders 88 and 89, see e.g Fig. 16 , limit the annular surface 87. In this way, the connecting part 80 is held precisely in the desired position on the connector 11, 12, 12 ', 13, 13', 21 so that it can rotate and at the same time is subject to axial movement, with the exception of a play to enable rotation , Db, Dc, prevented. The connecting part 80 can be used with a view to the electrical Connections inside the connector can be rotated about the axis A 'by an angle <360 degrees, for example within an angular range with a size of between about 300 degrees and about 350 degrees. The angular range can be limited by stops on the base part 11b, 12b, 12b', 13b, 13b', 21b and on the connecting part 80.

Ball pressure devices 83 are provided on the storage section 81, which, in the assembled state of the connector, exert a radial pressure force on the base part 11b, 12b, 12b ', 13b, 13b', 21b in the area of the annular surface 87. Twisting Da, Db, Dc of the connecting part 80 and thus the lamp 1, 2 therefore requires overcoming a certain resistance. The required torque can be applied by hand without difficulty and at the same time prevents unwanted adjustment of a selected rotational position. The annular surface 87 is also provided with recesses 87a, preferably evenly spaced apart from one another in the circumferential direction, into which a spring-loaded ball of one of the ball pressure devices 83 can releasably snap into place. When turning Da, Db, Dc, a defined rotational position can be haptically perceived by the operator. The depressions 87a can, for example, be arranged regularly, for example at angular intervals of 30 degrees. In addition, the locking of the ball pressure device(s) 83 can contribute to further improved locking of the selected rotational position. In other exemplary embodiments, the depressions can be omitted and the twists Da, Db and/or Dc can be performed continuously.

In some variants, the storage section 81 can also be fixed against larger forces with the aid of a screwing device, for example with the aid of a threaded hole in the base part 11b, 12b, 12b', 13b, 13b', 21b and a clamping screw.

Fig. 16 for example shows the assembly of the shell parts 12s, 12t of the T-type node connector 12, where the in Fig. 16 illustrated assembly principle can be applied analogously to the other node connectors described here, such as 11, 12 ', 13, 13', 21. The shell parts 12s, 12t are fixed to one another by means of screws 97 and screw domes 95, 96 inside the base part 12b.

The connecting part 80 has an opening 80a in the axial direction in a wall section 80b that extends in the radial direction inside the connecting part 80. The opening 80a is closed by means of an element 98 formed with a closure wall 98a, the element 98 being attached to the wall section 80b and thus connected to the part 80. In the assembled state of the connector, the closure wall 98a delimits the interior 14 of the same in the area of the connection area 41, to which the Closure wall 98a is assigned. A through opening 99 is formed in the closure wall 98a. Locking geometries 99b are provided on both sides of the through opening 99 on the element 98, each of the geometries 99b being able to interact with one of the locking geometries 67a formed on both sides of the socket-like component 61. In this way, the component 61 can be fastened in a snap-locking manner to the element 98 and thus to the connector in the area 41 in order to configure this area 41 in such a way that the electrical plug connection 60 is produced when the lamp 1 or 2 and the connector are joined together. Here, the component 61 extends through the through opening 99 parallel to the insertion section 90 and is accommodated in sections in the opening 99. The socket 61 thus projects essentially in the same direction as the section 90 from the connecting part 80 towards the lamp 1, 2, and an extension direction 61e of the component 61 corresponding to a mating direction of the plug connection 60 is therefore essentially parallel to the axis of rotation A 'and to the longitudinal extension direction L of the lamp 1 or 2 coupled in this connection area 41.

If an electrical connection in the area 41 is not desired, the latching connection of the component 61 with the element 98 is released and the component 61 is instead releasably attached to the inside of the closure wall 98a. For this purpose, the closure wall 98a has a storage area 84 on its side facing the interior 14 of the connector, which can accommodate the component 61. To fasten the component 61 in the area 84, one of the locking geometries 67a can be inserted into a guide rail 85 'formed on the wall 98a. On a side opposite this locking geometry 67a, the component 61 is held releasably by means of a screw-clamping device 85. The screw-clamping device 85 is formed with a screw dome 85a on the wall 98a, a screw 85b and a holding element 85c that can be tensioned against the component 61 by means of the screw 85b. The component 61 can thus be pulled inwards out of the opening 99 after loosening the locking geometries 99b and 67a and secured in the storage area 84. Here, the component 61, after being arranged and fixed in the area 84, covers the opening 99, thereby preventing access from outside through it. The extension direction 61e of the component 61 fastened in the region 84 runs essentially parallel to the wall 98a and perpendicular to the axis of rotation A'. In this storage position of the component 61, the electrical plug connection 60 is omitted when the area 41 'is plugged together with a connection area on the lamp side.

Fig. 14 and 15 show an example of the storage and use position of the component 61 for one of the connection areas 41 in an exploded view, where It is understood that the component 61 is attachable in each area 41 either in the storage position or instead in the use position.

On the back, each of the components 61 is designed with contacting means, which enable the poles of the several sockets 61 to be connected within the base part 11b, 12b, 12b ', 13b, 13b' or 21b, for example by means of flexible, insulated lines, which allow the sockets 61 to move relative to each other. Preferably, all of the sockets 61 of the connector 11, 12, 12 ', 13, 13', 21 are connected to one another via flexible lines for the operating current and the control signals in such a way that an electrical coupling of all lights 1 and / or that can be connected to the respective connector 2 - unless the electrical connection is prevented in one or more connection area(s) 41 ' - are electrically coupled via the connector. For example, the poles of the components 61 within the connector 11, 12, 12', 13, 13', 21 can be connected to one another in parallel. Flexible lines and contacting means, such as terminals, for interconnection are accommodated in the interior 14 of the connector 12 formed after the shell parts 12s, 12t have been assembled. The flexible lines are not shown in the figures for better clarity.

Attaching a lighting device formed with the modular system described above, such as the device 100, 200, 300, 400, 500, is possible by hanging it from a structure or by mounting it on a surface such as a wall or ceiling.

Show by example Fig. 10, 11 , 13-17 a fastening device 70 which is arranged on the connector 12 and enables it to be suspended via a rope 75. Each of the node connectors described above, for example connectors 11, 12, 12', 13, 13', 21, may be adapted to attach the lighting device, some or all of the connectors being used to attach a lighting device as required. In addition, the end cover 4, 4 ', 6 and the linear connector 5 can also be set up in an analogous manner for attaching the lighting device.

Fig. 20 shows the linear connector 5 when coupling two lights 1 and 2. The linear connector 5 does not allow the lights 1, 2 to be rotated relative to one another. For the electrical connection, the connector 5 has a plug-socket combination component 64, and for the mechanical connection a profile-like element, which is in Fig. 20 connected to a fastening device 70 for suspension by means of a rope 75 and is designed as an insertion section 90 on both sides. Each of the insertion sections 90 in Fig. 20 is again designed to engage in the groove 92 of the lamp 1 or 2. As described above, the connector also has 5 in Fig. 20 Ball pressure devices 45 and screw devices 46 are provided. The element forming the sections 90 and the component 64 may be connected to each other or provided separately. In addition to the element forming the sections 90 and the plug-socket combination component 64, an elbow piece 68 is provided, which can be connected to the element forming the sections 90 and/or the component 64 or provided separately. The arch piece 68 is designed to be axially stepped in order to engage on both sides on the inside of the covers 94 of the lights, here 1 and 2, and thereby ensure that the lights are aligned.

In the lighting arrangements created using the system described, for example the arrangements 200, 300, 400, 500, coupled lights 1 and/or 2 can each be rotated relative to the base part 11b, 12b, 12b', 13b, 13b', 21b of the node connector 11 , 12, 12 ', 13, 13', 21 or their further variants, which have connection areas 41, 41', are provided. Such further variants can also include a connector with two areas 41 and rotatability but aligned alignment of the longitudinal extents L of the coupled lights 1 and 2.

Thus, the lights 1, 2 can be rotated in the state coupled to one of the node connectors 11, 12, 12 ', 13, 13', 21 about their longitudinal axis A and longitudinal extension direction L, which are congruent with the axis A', and thereby, for example, horizontally Room-arranged lights 1 or 2, for example, alternatively illuminate the room or floor, in the sense of direct lighting, or illuminate the ceiling, in the sense of indirect lighting, or, if the lights 1 or 2 are attached near the wall and z. B. are aligned virtually parallel to this, also illuminating it specifically. Illumination of any area in the room is also possible.

Lights coupled using the linear connector 5 cannot be rotated relative to one another. Thus, in the device 100 the Fig. 1 There is no rotation, in the case of the device 200, for example, the left-hand branch extending from the connector 13 with three lights 1 and one light 2 can only be used as a whole relative to the base part 13b of the connector 13 and relative to others connected to the connector 13 and not lights shown in more detail can be rotated.

It goes without saying that, for example, the rotatability of the two lights 2 relative to one another at the in Fig. 3 arranged at the rear and additionally designated by reference number K Node connector 11, as a property of a component group with the lights 2 and the connector 11, K, enables the oblique arrangement of the right rear branch with one light 2 and two lights 1. This rotatability of the lights relative to one another as a property of this component group is fundamentally also present if, for example, the device 500 is fixed in space in the form shown and the rotation of the obliquely upward-pointing branch around its longitudinal direction and/or transversely to it is prevented by external fixation. However, within the lighting device 500, for example, there are also lights 2 which are arranged between two node connectors 11, 13 'or 12, 13 without the action of a linear connector 5 and thus also in the mounted, spatially fixed state of the node connectors 11, 13' or 12, 13 can still be rotated between the connectors 11, 13 'or 12, 13.

In both cases - rotatability before fixing the lighting device in the room, rotatability even after fixing it in the room - the twisting as a property of a component group with luminaire(s) and connector(s) allows a beam direction 1000 to be changed, depending on the spatial arrangement of the luminaire 1 , 2 to be able to illuminate a ceiling or wall or any other desired location in a room.

In a variant of the lighting system described above, so-called "dummy" elements, i.e. intermediate pieces with the external shape of a lamp, in particular elongated cylindrical, can be provided in addition to the lamps 1, 2. These "dummy" elements can be coupled mechanically in the same way as the lights 1, 2 with the node connectors or the linear connector 5 as described above. The "dummy" elements could in particular also be designed for electrical plug connections 60 at the front ends, analogous to lights 1 or 2, with the operating current and control signals then being passed on from one front end to the other of the "dummy" element. A “dummy” element without any electrical connection at the front ends is also conceivable.

Although the present invention has been fully described above using preferred exemplary embodiments, it is not limited to this but can be modified in a variety of ways.

In particular, other cross sections of the lights, other than a circular cross section, are conceivable, provided that the bearing sections 81 enable rotation, for example by making the bearing surface circular.
