Description

FIELD OF THE INVENTION

[0001] The invention relates to a connector for coupling a first and a second light to form a lighting arrangement. Furthermore, the invention relates to a lighting arrangement comprising such a connector and a first and a second light coupled to one another by means of the connector. TECHNICAL BACKGROUND

[0002] DE 10 2015 214 958 A1 describes a connecting element for a profile lighting arrangement. A first and a second profile light can be mechanically and electrically connected by means of the connecting element. The connecting element is described as being equipped with a hinge joint and additionally with pivot joints. A first of the pivot joints has a first connecting section that can be coupled to the first profile light, and a second of the pivot joints has a second connecting section that can be coupled to the second profile light. By means of the pivot joints, the first and second profile lights can each be rotated about a rotation axis that is oriented transversely or obliquely to the pivot axis of the hinge joint.

[0003] Another connecting element for a profile lighting arrangement is described in DE 10 2015 214 952 A1.

[0004] It would be desirable to be able to install a variety of lighting solutions on a construction site in a mechanically stable and simple manner, without time-consuming cabling work, and to adapt to the specific spatial conditions of the installation situation, such as the shape of a room, without the need for custom-made components. A flexible and reliable design that can be implemented even more compactly than before would be desirable. SUMMARY OF THE INVENTION

[0005] Against this background, it is an object of the invention to provide an improved connector for luminaires that not only enables the uncomplicated, rapid realization of diverse lighting arrangements that can be adapted to environmental conditions, particularly geometric or structural ones, but can also be constructed even more compactly than conventional connectors. Furthermore, it is an object of the invention to propose a correspondingly improved lighting arrangement.

[0006] According to the invention, this object is achieved by a connector having the features of claim 1 and / or by a lighting arrangement having the features of claim 14.

[0007] Accordingly, a connector for coupling a first and second luminaire to form a lighting arrangement is proposed, comprising a first connector part and a second connector part, wherein a first connector-side connection region is coupled to the first connector part and a second connector-side connection region is coupled to the second connector part. The connector-side connection regions are each designed for mating with a luminaire-side connection region of one of the luminaires along a longitudinal direction of the luminaire for releasably mechanically connecting the luminaire to the connector. Furthermore, the connector-side connection regions are each designed, configured, or configurable for releasably electrically connecting the luminaire to the connector by means of mating, at least for transmitting an operating current.

[0008] In the invention, the first and second connector parts are connected to one another in a pivot joint, wherein the pivot joint enables pivoting of the connector parts relative to one another about a pivot axis that runs obliquely to the longitudinal direction of the first light and to the longitudinal direction of the second light. The pivot joint has a hollow section formed on one of the connector parts and extending into the other of the connector parts. The hollow space surrounds the pivot axis and electrical conductors for electrically coupling the connector-side connection areas are passed through the hollow space.

[0009] According to the invention, a lighting arrangement is further proposed, comprising a first and a second luminaire, each with at least one luminaire-side connection region, as well as a connector according to the invention with a first and a second connector part. A connector-side connection region is coupled to each of the first and second connector parts. The first and second luminaires are coupled to one another by means of the connector.

[0010] One idea underlying the invention is that the alignment of the connector parts and the longitudinal directions of the lights relative to one another is not rigidly fixed, but can be flexibly adjusted by rotating the connector parts relative to one another about the inclined pivot axis. By having the cavity of the hollow section surround the pivot axis, extend into the other connector part, and guide the electrical conductors through this cavity, the connector of the present invention can be constructed even more compactly. Guiding the conductors through the cavity adjacent to the pivot axis helps to minimize the mechanical stress on the conductors during the pivoting process.

[0011] The invention thus enables a flexible arrangement of luminaires within a system, for example, to effectively illuminate stairwells or other spaces, especially those with irregular geometric shapes or angles. Custom-made connectors for luminaire alignments that deviate from standard angles can be avoided. The particularly compact design of the connector also allows for a design that, together with the luminaires, is aesthetically pleasing.

[0012] In addition, the lights can be mechanically and, in particular, electrically coupled in a simple and stable manner by plugging them together with the connector.

[0013] The invention thus makes it possible to quickly and easily connect luminaires in a way that is flexibly adaptable to the ambient conditions, thus creating versatile lighting solutions for a wide variety of applications. When setting up a luminaire network, for example, with a large number of luminaires and such connectors, cumbersome cabling can be avoided.

[0014] Advantageous embodiments and further developments of the invention emerge from the further subclaims and from the description with reference to the figures.

[0015] In one embodiment, the connector for connecting the lights to the connector is designed such that the first light can be rotated about a first axis of rotation relative to the first connector part, and the second light can be rotated about a second axis of rotation relative to the second connector part. In this embodiment, the pivot axis, about which the pivoting of the connector parts relative to one another is enabled by means of the pivot joint, is designed as a third axis of rotation running obliquely to the first and second axes of rotation. Preferably, the lights can be rotated independently of one another about the first and second axes of rotation.In combination with the pivot axis designed as a third rotation axis, the lighting arrangement formed with the luminaires connected via the connector can be adapted, for example, to the shape of a room, such as a staircase, while at the same time the desired beam direction of the luminaires can be easily adjusted.

[0016] In particular, it can be provided that the first axis of rotation coincides with or is parallel to the longitudinal direction of the first luminaire, and that the second axis of rotation coincides with or is parallel to the longitudinal direction of the second luminaire. This can be advantageous, for example, with regard to the alignability of the main beam directions of the luminaires regardless of the overall shape of the lighting arrangement.

[0017] According to a further development, the connector is designed such that the first and second axes of rotation can be selectively aligned by pivoting the first and second connector parts relative to one another such that the first and second axes of rotation substantially coincide, and can be aligned such that the first and second axes of rotation enclose an angle other than zero with one another, in particular they can be pivoted relative to one another by an angle of up to 60 degrees or by an angle of up to 90 degrees. Thus, advantageously, straight and angled arrangements with the coupled first and second lights can be formed using the same connector. The angle other than zero between the first and second axes of rotation can, for example, be freely selectable up to the maximum angle.

[0018] In one embodiment, the connector comprises a first connecting part, which is mounted on the first connector part so as to be rotatable about the first axis of rotation and on which the first connector-side connection region is formed. Furthermore, in this embodiment, the connector comprises a second connecting part, which is mounted on the second connector part so as to be rotatable about the second axis of rotation and on which the second connector-side connection region is formed. In particular, the connecting parts are rotatable independently of one another relative to the connector parts. In this way, the rotatability of the lights can be expediently implemented.

[0019] According to a further development, the pivot axis, about which the pivoting of the connector parts relative to one another is enabled by means of the pivot joint, is inclined relative to the longitudinal direction of the first light and the longitudinal direction of the second light by an angle that is essentially the same in amount. The angle can in particular be selected in a range from essentially 15 degrees to essentially 45 degrees and can, for example, be approximately 30 degrees or approximately 45 degrees. Other angles are also conceivable. This further development makes it possible to align the connector parts such that the longitudinal directions of the first and second light coincide or are parallel, and to vary the angle between the longitudinal directions within an angular range by selecting a different pivot position.

[0020] In one embodiment, the hollow section is formed, at least in sections, as a circular hollow cylinder. This facilitates pivotal movement of the hollow section relative to the other connector part, and furthermore, such a hollow section can be conveniently manufactured.

[0021] According to a further embodiment, the hollow section creates a passage from an interior of the first connector part to an interior of the second connector part. This enables the electrical coupling of the connector-side connection areas by means of the electrical conductors in a simple manner and facilitates the mobility of the electrical conductors.

[0022] In one embodiment, the hollow section is provided with an external thread onto which a nut, in particular a grooved nut, is screwed in the other of the connector parts, whereby the first and second connector parts are held together along the pivot axis about which the pivoting of the connector parts relative to each other is enabled by means of the pivot joint. Thus, the connector parts can be easily assembled and reliably held together, while the electrical coupling of the connector-side connection areas is not hindered.

[0023] In particular, the hollow portion may extend through a through-opening into the other of the connector parts.

[0024] In a further development, it is provided that the first connector part is formed with a circumferential wall and a substantially flat first end wall that is inclined at an angle to the longitudinal direction of the first light, that the second connector part is formed with a circumferential wall and a substantially flat second end wall that is inclined at an angle to the longitudinal direction of the second light, that the first and second end walls each run substantially perpendicular to the pivot axis about which the pivoting of the connector parts relative to one another is made possible by means of the pivot joint, and that the first and second end walls are arranged adjacent to one another. In this further development, the hollow section protrudes from the end wall of one of the connector parts and projects through a through opening in the end wall of the other of the connector parts.This allows the compact connector to be designed even more aesthetically pleasing. This refinement can facilitate the continuation of the outer contour of the luminaires through the outer contour of the connector parts and also enables a visually interesting angle of the lighting arrangement in the area of the swivel joint, especially with a defined corner. The swivel joint can thus be effectively and discreetly concealed.

[0025] In one embodiment, the through-opening is circular. This further facilitates pivoting mobility relative to the hollow section.

[0026] According to a further development, the hollow section protrudes centrally from the end wall of one of the connector parts, in particular substantially coaxial with the pivot axis, and the through-opening is provided centrally in the end wall of the other of the connector parts, in particular substantially coaxial with the pivot axis. This configuration can contribute to further improving the appearance of the lighting arrangement formed with the connector and the lights for the various pivot positions of the connector parts.

[0027] In one embodiment, the end walls of the two connector parts are preloaded against each other by means of a spring element, in particular a spring element surrounding the hollow section on the circumference, preferably a disc spring. In this way, undesirable independent rotation of the connector parts relative to each other is prevented, as a certain amount of force is required to pivot them due to friction between the two connector parts. A set pivot position of the connector parts is thus precisely maintained in this embodiment. A spring element surrounding the hollow section on the circumference also enables uniform application of the frictional forces in the circumferential direction around the pivot axis.

[0028] According to a further development, the spring element acts on an inner side of the end wall of the other connector part, which is provided with the through-opening. The spring element thus acts on a surface that is invisible to the observer when the connector is assembled, thus preventing any possible impairment of the appearance of visible surfaces due to the application of force or possible frictional relative movement.

[0029] The spring element can be preloaded against the inside of the end wall with the through-hole by means of the nut screwed onto the hollow section. This allows for precise adjustment of the friction force and the torque required to pivot the connector parts.

[0030] In one embodiment, the peripheral wall of the first connector part is arranged substantially coaxially with the first axis of rotation, and the peripheral wall of the second connector part is arranged substantially coaxially with the second axis of rotation. The peripheral walls can have a circular outer contour perpendicular to the axis of rotation. In this way, a round outer contour of the lights can, for example, be continued substantially seamlessly in the connector parts and remains essentially unchanged for the observer when the beam direction of the lights is adjusted, with the exception of the bending achieved by the pivot joint.

[0031] According to one embodiment, one of the end walls is formed with a guide groove that follows a first circular path, and the other of the end walls is formed with at least one guide projection designed to engage in the guide groove, in particular a guide projection corresponding to the guide groove and following a second circular path, wherein the guide projection engages in the guide groove. In particular, the pivot axis is defined by the interaction of the at least one guide projection with the guide groove. The radii of the first and second circular paths are preferably the same. This embodiment contributes to stable guidance of the connector parts to one another and enables precise function of the pivot joint.In addition, a guiding function for the pivoting movement around the pivot axis as well as a holding and pre-tensioning function axially in the direction of the pivot axis can be implemented in this way, each by means of elements specifically designed for this purpose.

[0032] Preferably, the guide groove and the guide projection are each formed in a closed circular ring. Alternatively, however, it is conceivable to provide the guide projection with interruptions along the second circular path, for example, if the guide groove is formed in a closed circular ring.

[0033] In a further development, one of the end walls is formed with an angular range definition groove that follows a third circular path and has an interruption point along the third circular path. In this further development, the other of the end walls is formed with an engagement projection designed to engage in the angular range definition groove. In particular, the engagement projection protruding at opposite ends of the angular range definition groove on both sides of the interruption point limits an angular range within which the two connector parts can be pivoted relative to one another. Thus, the angular range within which pivoting is possible can be effectively limited, for example, to a size of slightly less than 360 degrees, for example, approximately 350 degrees.This prevents damage to the electrical conductors due to excessive relative twisting of the connector parts around the pivot axis.

[0034] The interruption point and the engagement projection can, for example, be arranged such that when the engagement projection abuts one of the ends of the angular range definition groove at the interruption point, the longitudinal directions of the first and second lights are inclined to one another by an angle which, in terms of amount, corresponds essentially to twice the angle by which the pivot axis is inclined relative to the longitudinal directions of the first and second lights.

[0035] According to a further development, the guide groove, the angular range definition groove, and in particular the guide projection are arranged concentrically, in particular coaxially, to the pivot axis. Preferably, the third circular path followed by the angular range definition groove has a larger radius than the first circular path. Advantageously, this allows the moment about the pivot axis that the engagement projection is able to withstand to be increased by a larger lever arm relative to the pivot axis. This results in an even more robust connector.

[0036] In one embodiment, the hollow portion, the guide projection, and the engagement projection are each arranged protrudingly on the first end wall of the first connector part. Furthermore, in this embodiment, the central through-opening, the guide groove, and the angle range definition groove are provided in the second end wall of the second connector part.

[0037] According to a further embodiment, the connector-side connection areas are each designed, configured, or configurable for the detachable electrical connection of the luminaire to the connector by means of plugging them together, at least for transmitting the operating current at mains voltage. In particular, the detachable electrical connection can comprise an electrical connection for transmitting an alternating current as the operating current and / or an electrical connection of an operating current at a nominal voltage in a range from approximately 100 volts to approximately 240 volts.

[0038] In a further development, the electrical connection of the luminaire to the connector additionally includes at least one electrical connection for transmitting a control signal, in particular a DALI signal. Thus, the connector can contribute to additional flexibility with regard to luminaire control.

[0039] In one embodiment, it can be provided that a component of an electrical plug connection is arranged or can be arranged and fastened in the first and second connector-side connection region in such a way that the component of the electrical plug connection can be plugged together with a corresponding counter-component of the electrical plug connection which is provided in the lamp-side connection region.

[0040] Furthermore, in a further embodiment, it can be provided that the first and second connector-side connection areas are each configurable such that, when plugged together with the luminaire-side connection area, the electrical connection of the luminaire to the connector can be brought about at the same time or the electrical connection can be omitted. In this way, if a lighting arrangement with multiple luminaires and connectors is intended to form a geometrically closed ring-like shape, the electrical coupling and thus a ring closure can be prevented at a desired connection point between the luminaire and the connector. In addition to the geometric adjustment options, the connector therefore also has a high degree of flexibility in electrical terms.

[0041] The electrical conductors guided through the cavity of the hollow section for electrically coupling the connector-side connection areas can in particular be designed as part of a flexible cable or can each be provided as individual, insulated, flexible wires.

[0042] According to one embodiment, the first and second luminaires are each elongated, preferably with at least a substantially constant outer cross-sectional shape, and each have, at least at one end thereof, the luminaire-side connection region, which is plugged together with one of the connector-side connection regions of the connector along a longitudinal direction of the luminaire. In particular, one or both of the luminaires can have, at both end thereof, a luminaire-side connection region, which can be selectively plugged together with one of the connector-side connection regions.

[0043] The above embodiments and further developments of the invention can be combined with one another as desired, where appropriate. Further possible embodiments, further developments, and implementations of the invention also include combinations of features of the invention described above or below with reference to the exemplary embodiments that were not explicitly mentioned. In particular, those skilled in the art will also add individual aspects as improvements or additions to the respective basic form of the present invention. TABLE OF CONTENTS OF THE DRAWING

[0045] The accompanying drawings are intended to provide a further understanding of embodiments of the invention. They illustrate embodiments and, in conjunction with the description, serve to explain principles and concepts of the invention. Other embodiments and many of the noted advantages will be apparent upon reference to the drawings. Elements of the drawings are not necessarily shown to scale relative to one another.

[0046] In the figures, identical, functionally identical and acting elements, features and components are provided with the same reference symbols unless otherwise stated. DESCRIPTION OF EMBODIMENTS

[0047] Fig. 1-5 show a connector 1 according to an embodiment in different states. The connector 1 serves to couple two elongated, Fig. 1-5 not shown lights and has a first connector part 12 and a second connector part 13, which are connected to each other in a pivot joint 14 and form two mutually adjustable legs of the connector 1.

[0048] The first connector part 12 comprises a housing component 20 formed as a hollow element with a circumferential, tubular peripheral wall 24 having a substantially circular outer cross-sectional shape, wherein the peripheral wall 24 surrounds an interior space 25 of the first connector part 12. One end of the first connector part 12 is closed by a substantially flat first end wall 72.

[0049] A first connection part 82 is mounted on the housing component 20 of the first connector part 12 so as to be rotatable about a first axis of rotation 32. A first connector-side connection region 22 is formed on the first connection part 82. The first axis of rotation 32 forms a longitudinal center axis of the peripheral wall 24 and coincides with a longitudinal direction L2 of a first lamp 2 or 2' to be coupled to the connector 1 in the connection region 22, see Fig. 9-15 , together.

[0050] The second connector part 13 has a housing component 21, which is formed as a hollow element with a circumferential, tubular peripheral wall 26 having a substantially circular outer cross-sectional shape, wherein the peripheral wall 26 surrounds an interior space 27 of the second connector part 13. One end of the second connector part 13 is closed by a substantially flat second end wall 73.

[0051] A second connection part 83 is mounted on the housing part 21 of the second connector part 13 so as to be rotatable about a second axis of rotation 33. A second connector-side connection region 23 is formed on the second connection part 83. The second axis of rotation 33 forms a longitudinal center axis of the peripheral wall 26 and coincides with a longitudinal direction L3 of a second lamp 3, 3' to be coupled to the connector 1 in the connection region 23, see Fig. 9-15 , together.

[0052] The connecting parts 82, 83 and the connector-side connection areas 22, 23 are each configured in the same way. The connecting parts 82, 83 are rotatable independently of one another relative to the connector parts 12, 13 about the first and second rotational axes 32, 33, respectively. A rotation angle of the connecting parts 82, 83 is limited in each case, and the connecting parts 82, 83 are each rotatable about the associated first and second rotational axes 32, 33 within the rotational angle range of less than 360 degrees, for example, within a rotational angle range of between 300 and 350 degrees. Each of the connecting parts 82, 83 can thus preferably perform almost a full rotation.

[0053] The connecting parts 82, 83 can be provided with radially outward acting ball pressure devices 84, see Fig. 5 , each having a spring-loaded ball that can exert pressure on a bearing surface of the housing component 20 or 21, respectively, in order to prevent undesired rotation of the connecting part 82, 83 with little effort about the associated axis of rotation 32 or 33. In particular, the bearing surface can have recesses into which the ball of the ball pressure device 84 can releasably engage, whereby the connecting part 82, 83 releasably engages in defined angular positions. However, such recesses can be omitted in variants.

[0054] The end walls 72, 73 are in the connector 1, see for example Fig. 4 and 5 , arranged parallel to each other and each inclined obliquely to the first axis of rotation 32 and to the second axis of rotation 33.

[0055] The connector-side connection areas 22, 23 are each designed for mating with a lamp-side connection area 52, 53 of one of the lamps 2 or 2', 3 or 3'. Mating takes place along the longitudinal direction L2 or L3 of the lamp 2 or 2', 3 or 3' to be coupled to the connector 1 by mating. The first lamp 2 or 2' can thus be mated with the first connection area 22 along the first rotation axis 32, and the second lamp 3 or 3' can be mated with the second connection area 23 along the second rotation axis 33. Fig. 10 illustrates, by way of example, a luminaire 2' or 3' with a luminaire-side connection region 52 or 53, which is arranged at one end of the luminaire 2' or 3'. A similarly designed luminaire-side connection region 52 or 53 is preferably arranged at the other end of the luminaire 2' or 3', in order to enable mating with a further connector 1. The second luminaire 3' is thus, by way of example, designed in the same way and provided with luminaire-side connection regions as the first luminaire 2'. However, a length of the luminaires 2', 3' can be different, for example. Luminaire-side connection regions 52, 53 of the luminaires 2, 3 of the Fig. 11-17 and furthermore from further lights 4, 5 in Fig. 16-17 are like the connecting areas 52, 53 of the lights 2', 3' in Fig. 9 und 10 trained.

[0056] By plugging together the connector-side and luminaire-side connection areas 22 and 52 or 23 and 53, the two luminaires 2', 3' or 2, 3 are each detachably mechanically connected to the connector 1. After plugging together, the first luminaire 2 or 2' on the connector 1, together with the connection part 82, can be rotated about the first axis of rotation 32, and the second luminaire 3 or 3' on the connector 1, together with the connection part 83, can be rotated about the second axis of rotation 33. By rotating the two luminaires 2 or 2', 3 or 3' independently of one another on the connector 1, the main beam directions H2, H3 of the first and second luminaires 2, 2', 3 and 3', respectively, can be changed with respect to the connector 1, see for example Fig. 11-14 .

[0057] For the mechanical connection of the luminaire 2 or 2' to the connector 1, an insertion section 90 with a stepped cross-sectional shape, axially projecting parallel to the longitudinal direction L2, is formed on the connecting part 82. A similar insertion section 90 is provided on the connecting part 83 for the mechanical connection of the luminaire 3 or 3'. The insertion sections 90 can each be inserted into an undercut groove 92 of a profile body 91 of the luminaire 2, 2', 3, or 3'. A ball pressure device 45 with a spring-loaded ball and a screw device 46, for example comprising a grub screw, are also provided on each of the insertion sections 90. The ball pressure device 45 enables the insertion section 90 to be locked onto the luminaire 2, 2', 3 or 3', for example by locking, releasable engagement of the ball in a corresponding recess within the groove 92.The screw device 46 offers an additional, reliable fixing option for securing the insertion section 90 in the groove 92.

[0058] In addition, each of the two connector-side connection areas 22 and 23 is designed or configured or configurable to detachably electrically connect the luminaire 2, 2' or 3, 3' to the connector 1 by plugging them together. Fig. 1-5 In the illustrated embodiment, the first and second connection areas 22, 23 are each configurable such that, upon mating with the luminaire-side connection area 52 or 53, the electrical connection of the luminaire 2, 2', 3, or 3' to the connector 1 can be selectively established at the same time, or the electrical connection can be omitted. If necessary, the electrical connection at the coupling point between the luminaire and connector 1 can thus be prevented. Alternatively, the configuration option that makes it possible to prevent the electrical coupling can be omitted, and the electrical connection can always be established upon mating.

[0059] The detachable electrical connection by plugging together the luminaire- and connector-side connection areas 22 and 52 or 23 and 53 enables, in the exemplary embodiments shown in the figures, a transmission of an operating current for the luminaires 2 or 2', 3 or 3' at mains voltage, wherein the operating current is transmitted as alternating current with a nominal voltage in a range from approximately 100 volts to approximately 240 volts. Furthermore, the detachable electrical connection by plugging together the luminaire- and connector-side connection areas 22 and 52 or 23 and 53 in the exemplary embodiments shown in the figures comprises an electrical connection for transmitting a control signal, in particular a DALI signal, for the purpose of controlling the luminaires 2 or 2', 3 or 3'.

[0060] For the electrical coupling of the first and second luminaires 2 or 2', 3 or 3' to the connector 1, in the exemplary embodiments illustrated in the figures, a component 61 of an electrical plug connection is arranged and fastened in each of the first and second connector-side connection regions 22 and 23 in such a way that the component 61 of the plug connection can be plugged together with a corresponding mating component 62 of the electrical plug connection, which is provided in the luminaire-side connection regions 52 and 53, along the longitudinal direction L2 of the first luminaire 2, 2' or the longitudinal direction L3 of the second luminaire 3, 3'. After plugging together, the component 61 and the mating component 62 interact as a multi-pole plug connection for transmitting the operating current and the control signal.In particular, corresponding poles of the components 61 in the two connector-side connection areas 22 and 23 are electrically connected to one another by means of conductors 40 within the connector 1.

[0061] The luminaire-side connection areas 52, 53 are of similar design, and the connector-side connection areas 22, 23 are of similar design. This creates flexibility for the coupling of luminaires 2 or 2', 3 or 3' and connectors 1. The luminaires 2, 2', 3, 3' are furthermore not only designed to be operated and controlled with the operating current received via one of the front-side connection areas 52 or 53 and the control signal received there for emitting light, for example by means of LED devices 50, but are preferably also designed to forward the operating current and the control signal from a luminaire-side connection area 52, 53 at one front end of the luminaire 2, 2', 3 or 3' to the luminaire-side connection area 52, 53 at the other front end of the luminaire 2, 2', 3 or 3' in order to enable coupling with further luminaires and connectors.

[0062] In the Fig. 1-5 In the embodiment shown, each of the connector-side connection areas 22, 23 can be configured, if necessary, to prevent the electrical connection. For this purpose, the component 61 attached to the connection part 82 or 83 can be detached and arranged and fastened in the interior 25, 27 of the connector part 12 or 13 on the connection part 82 or 83 in such a way that when plugged together with the lamp-side connection area 52 or 53, there is no interaction with the mating component 62.

[0063] The pivot joint 14 of the connector 1 enables the connector parts 12 and 13 to pivot relative to one another about a pivot axis 34. The pivot axis 34 is designed as a third axis of rotation and runs obliquely to the first axis of rotation 32 and the second axis of rotation 33. The pivot axis 34 intersects the first axis of rotation 32 and the second axis of rotation 33, and thus the longitudinal direction L2 and the longitudinal direction L3 of the luminaires 2 or 2' or 3 or 3', respectively, at an angle α of the same magnitude, the size of which is selected in a range from substantially 15 degrees to substantially 45 degrees, see Fig. 5 For example, α can be about 30 degrees, as in Fig. 5 shown, or approximately 45 degrees. Perpendicular to the pivot axis 34 is an imaginary pivot plane 35, which runs parallel to the end walls 72 and 73 centrally between them and is thus inclined to the longitudinal directions L2, L3. Each of the first and second axes of rotation 32, 33, and thus also to the longitudinal directions L2, L3, is inclined to the pivot plane 35 by an angle β, where (α + β) = 90 degrees.

[0064] The design of the swivel joint 14 in the connector 1 of the Fig. 1-5 is described in more detail below.

[0065] The pivot joint 14 of the connector 1 is formed by the connector parts 12, 13 interacting in the region of the end walls 72, 73. The housing component 20 of the first connector part 12 is formed integrally with a hollow section 15 protruding centrally from an outer side of the end wall 72 and coaxial with the pivot axis 34. The hollow section 15 is circularly cylindrical, has a continuous cavity 16 with a substantially constant and circular internal cross-section, and is also provided with an external thread 15a on an outer circumference.

[0066] In the assembled state of the connector 1, the first and second end walls 72, 73 are arranged parallel and adjacent to one another. The hollow section 15 projects from the end wall 72 of the first connector part 12 through a circular, central through-opening 17 in the end wall 73 of the second connector part 13, arranged coaxially with the pivot axis 34, into the second connector part 13. The hollow section 15 is arranged with radial play in the through-opening 17.

[0067] In the interior 27 of the second connector part 13, a grooved nut 18 is screwed onto the hollow section 15 extending into the interior 27 using the external thread 15a. A spring element, for example a disc spring 19, is arranged between the grooved nut 18 and an inner side of the end wall 73. The disc spring 19 surrounds the hollow section 15 in its circumferential direction. By screwing on the grooved nut 18, the connector parts 12, 13 can be resiliently preloaded against one another; moreover, the connector parts 12, 13 are held together in this way. By means of the effect of the disc spring 19 preloaded against the inner side of the second end wall 73, a uniform preload force can be exerted in the circumferential direction around the pivot axis 34.

[0068] The hollow section 15 is rotatable in the through-opening 17 about the pivot axis 34. To guide the rotational movement, particularly also in the radial direction, a guide groove 74 is also formed on the outside of the second end wall 73 of the connector 1. The guide groove follows a first circular path whose center lies on the pivot axis 34. Thus, the guide groove 74 extends in a closed circular ring around the through-opening 17.

[0069] A guide projection 75, formed integrally with the first end wall 72 and designed to engage in the guide groove 74, protrudes from the outside. The guide projection 75, as a closed circular projection, follows a second circular path that corresponds to the first circular path of the guide groove 74 and has the same radius as the first circular path. To define the pivot axis 34 and guide the pivoting movement about the pivot axis 34, the guide projection 75 engages in the guide groove 74 and provides axial and radial guidance, see the sectional views of the Fig. 4 and 5 In a variant, the guide projection 75 could, for example, be replaced by a plurality of individual projections arranged along the second circular path with interruptions between them.

[0070] To limit the angular range of the pivoting movement around the pivot axis 34, an angular range definition groove 76 is formed on the outside of the second end wall 73, which follows a third circular path and has an interruption point 77 along the third circular path. The third circular path runs concentrically to the first circular path of the guide groove 74 and has a larger radius than the first circular path.

[0071] Furthermore, a pin-like engagement projection 78, which is formed integrally with the first end wall 72, protrudes on the outside and is designed to engage in the angular range definition groove 76.

[0072] In the assembled state of the connector 1, the guide groove 74, the angle range definition groove 76, the through hole 17, the guide projection 75 and the hollow portion 15 are arranged coaxially to each other and to the pivot axis 34.

[0073] During the rotation of the two connector parts 12 and 13 relative to each other about the pivot axis 34, the engagement projection 78 runs in the angular range definition groove 76. By the engagement projection 78 being located at opposite ends of the angular range definition groove 76 on both sides of the interruption point 77, an angular range within which the two connector parts 12, 13 can be pivoted relative to each other is limited, wherein the angular range has a size of less than 360 degrees, for example approximately 350 degrees.

[0074] The hollow section 15, by means of its cavity 16, creates a passage from the interior 25 of the first connector part 12 to the interior 27 of the second connector part 13. Electrical conductors 40 for electrically coupling the components 61 of the connector-side connection areas 22 and 23 are passed through the cavity 16, which surrounds the pivot axis 34. The electrical conductors 40 can be arranged with flexibility and play, see Fig. 5 , but without detours from the first connector-side connection area 22 to the second connector-side connection area 23. For this purpose, the conductors 40 are, for example, components of a flexible cable or, as exemplified in Fig. 5 illustrated, formed as individual flexible, insulated veins.

[0075] The central guidance of the conductors 40 through the hollow section 15 in the region of the pivot axis 34, together with the limitation of the angles of rotation about the axes 32, 33 and 34, as described above, makes it possible to pivot the connector parts 12, 13 relative to one another, as well as the connection parts 82, 83 on the respective connector part 12 or 13, without excessively stressing the electrical conductors 40.

[0076] By equipping the connector 1 with the pivot joint 14, the first and second axes of rotation 32, 33 can be selectively aligned with one another at a wide variety of angles within an angular range from 0 degrees up to a maximum angle of δ = 2α by pivoting the first and second connector parts 12, 13 relative to one another. With the angle of α = 30 degrees illustrated in the figures, δ = 60 degrees. With an alternative angle of, for example, α = 45 degrees, δ = 90 degrees, whereby the connector can be converted from a rectilinear shape into a rectangular L-shape. This makes it possible to construct lighting arrangements with coupled luminaires 2 or 2', 3 or 3', which can be adapted to a wide variety of geometric or structural environmental conditions or design requirements using a connector 1 of the same type.

[0077] Fig. 6-8 also show that the interruption point 77 and the engagement projection 78 can be arranged on the end walls 73, 72 in such a way that in one of the pivoting directions about the axis 34, thus when the engagement projection 78 is on one side, in Fig. 7 the left side, the interruption point 77, the maximum angle of δ = 2α can be realized and is preferably achieved precisely. For this purpose, it can be provided, for example, that the projection 78 lies with its center taken in the circumferential direction on a plane of symmetry of the housing component 20, which contains the pivot axis 34, while the center of the interruption point 77 is rotated around the pivot axis 34 by a, in particular small, angle ε from an analogous plane of symmetry of the housing component 21 containing the axis 34, see Fig. 7 The angle ε is in Fig. 7 illustrated slightly distorted and corresponds in particular to the sum of half the extension of the engagement projection 78 and half the extension of the interruption point 77, each taken in the circumferential direction as an angle around the axis 34.

[0078] Fig. 11 shows a detail of a lighting arrangement 100 according to an embodiment, which comprises a first and second lamp 2, 3 and a connector 1 according to Fig. 1-5 The lights 2 and 3 are elongated and each have a substantially constant, substantially round outer cross-sectional shape. The lighting arrangement 100 can include more than two lights 2, 3 and more than one connector 1. By means of the connector 1, the first light 2 and the second light 3 are mechanically and electrically coupled to one another, wherein the longitudinal directions L2, L3 of the two lights 2, 3 are inclined to one another by an angle that is smaller than the maximum angle δ. Fig. 11 In addition, the luminaire 2 protrudes from the drawing plane at an angle toward the viewer. For this purpose, the two connector parts 12 and 13 were rotated relative to each other about the pivot axis 34. The arrangement of the pivot joint 14 and the inclined end walls 72, 73 enables the angled design of the lighting arrangement 100, in which the outer shapes of the connector parts 12, 13 largely seamlessly continue the outer cross-sectional contour of the luminaires 2, 3 and form an aesthetically pleasing corner 36 in the pivot plane 35.

[0079] After coupling to the connector 1, the first luminaire 2 can be rotated about its longitudinal axis L2, which corresponds to the rotation axis 32, and the second luminaire 3 can be rotated about its longitudinal axis L3, which corresponds to the rotation axis 33. In this way, a main beam direction H2, along which the first luminaire 2 emits light, and a main beam direction H3, along which the second luminaire 3 emits light, can be adjusted relative to the connector 1. Fig. 11 An exemplary alignment of the main radiation directions H2, H3 is sketched, with the main radiation direction H2 pointing diagonally backwards into the plane of the drawing.

[0080] Fig. 12 shows a lighting arrangement 100' according to a further embodiment, which in turn comprises the lights 2, 3 and the connector 1 coupling them. The lighting arrangement 100' differs from the lighting arrangement 100 of Fig. 11 only on the one hand in that the connector parts 12, 13 in Fig. 12 at a different angle than in Fig. 11 are rotated around the pivot axis 34, whereby the longitudinal directions L2 and L3 of the lights 2, 3 in Fig. 12 are inclined at an angle of approximately 60 degrees to each other, and on the other hand in a modified exemplary orientation of the main beam directions H2, H3. Again, the outer contours of the connector parts 12, 13 form an aesthetically advantageous corner 36'. The angle between the longitudinal directions L2, L3 corresponds in the example of the Fig. 12 the maximum angle δ.

[0081] The lighting arrangement 100' is again in the Fig. 13 and 14 for other exemplary relative orientation possibilities of the main beam directions H2, H3. For example, in Fig. 13 the main radiation direction H2 out of the plane of the drawing, whereas in Fig. 14 the main beam directions H2, H3 point obliquely to each other in the angular range enclosed by the luminaires 2, 3.

[0082] Fig. 15 illustrates a lighting arrangement 100" according to yet another embodiment, in which the connector parts 12, 13 are rotated relative to one another about the pivot axis 34 such that the rotation axes 32, 33 and thus the longitudinal directions L2 and L3 of the first and second lights 2, 3 coincide and are thus identical. In this way, the formation of a linear, rectilinear arrangement of the lights 2, 3 by means of the connector 1 is also achieved.

[0083] Fig. 16 und 17 schematically show a lighting arrangement 100‴ for illuminating a stairwell intended for use by persons 99. The lighting of the stairwell is shown only as an example; the use of such a lighting arrangement in many other applications, for example for other types of rooms, is equally conceivable according to further embodiments.

[0084] The staircase of the Fig. 16 und 17 has an irregular shape and is to be illuminated by a staircase and the structural conditions using the 100‴ lighting arrangement. In Fig. 17 For example, in the bottom left corner of the stair landing there is a structural obstacle that is to be avoided by the 100‴ lighting arrangement.

[0085] For this purpose, the lighting arrangement 100‴ comprises a plurality of elongated lights, of which, for example, the first to fourth lights 2 to 5 are arranged in Fig. 16-17 The luminaires 2-5 are mechanically and electrically coupled to each other one after the other by means of a connector 1 arranged between them. To adapt to the shape of the staircase, luminaires 3 and 4 are shorter than luminaires 2 and 5. In addition, the connector parts 12, 13 of the three in Fig. 16 und 17 connector 1 shown as an example, which as shown in Fig. 1-8 are formed, each adjusted differently relative to one another about the pivot axis 34, so that the angles between the longitudinal directions of the lights 2 and 3, 3 and 4, and 4 and 5 connected by means of the connector 1 are each different. The main beam directions of the lights 2-5 are also suitably adjusted by rotating them about the axes of rotation 32, 33 relative to the connectors 1. The lighting arrangement 100‴ can be fastened, for example, in the area of the connectors 1 or, after adjusting the main beam directions, in the area of the lights 2-5.

[0086] Fig. 16-17 demonstrate that, using the adjustable connectors 1 in conjunction with the luminaires 2-5, lighting arrangements can be created that can be highly flexibly adapted to a wide variety of conditions without the need for custom-made components. The spring preload provided by the disc spring 19 advantageously prevents unwanted adjustment of the selected shape.

[0087] The luminaires 2-5 can emit light in different ways. For example, the luminaires 2-5 can be equipped with reflectors, such as Fig. 11-15 , for targeted illumination of certain areas of the room, or with an opal cover for more diffuse illumination, as exemplified in Fig. 9-10 for the lights 2', 3' shown, or be equipped in another suitable manner for emitting light. In each of the embodiments of the Fig. 11-17 Alternatively, luminaires 2', 3' can be installed according to Fig. 9-10 be used.

[0088] Although the invention has been fully described above using preferred embodiments, it is not limited thereto but can be modified in many ways. LIST OF REFERENCE SYMBOLS
