FIXING DEVICE FOR A FLEXIBLE TUBE-FORM LIGHTING DEVICE, AND ARRANGEMENT

FIELD OF THE INVENTION

The invention relates to the field of lighting devices and in particular to a fastening device for a lighting device. In addition, the invention relates to an arrangement with such a fastening device.

TECHNICAL BACKGROUND

Although the invention can be useful in many areas in which it is desirable to achieve a lighting effect, the invention and the problem on which it is based are to be explained below using the example of a lighting device for achieving an aesthetic lighting effect, particularly in the interior of a building , will be explained in more detail.

It is generally known to provide luminaires or luminous elements in an interior area of a building, such as a premises, not only to illuminate the premises, i.e. to illuminate them, but also for the purpose of achieving an aesthetic effect and/or to design the light emission differently in different areas of the room. With regard to a flexible, unhindered ability to design the lighting effects, however, there are limitations in conventional lighting devices which it would be desirable to overcome.

The document JP S51-5881 U shows a lighting device in which individual lamp sockets are connected by means of a flexible tube.

The document CN 208 859 362 U deals with a string-like lamp with suction cups for attachment to a wall.

The document CN 209 068 236 U also describes a wall mounting of a strip-like lamp.

The document EP 3 369 989 A1 deals with a fastening system for flush mounting a device, such as a lamp, in a wall and/or ceiling through a hole in the latter.

A lamp provided for coupling to an electrical/electronic installation device is described in document EP 3 527 886 A1, wherein the lamp is described as being fixed to an attachment of the installation device by the interaction of a counter magnet with a coupling magnet.

SUMMARY OF THE INVENTION

Against this background, the invention is based on the object of specifying an improved fastening device which makes it possible to arrange and fasten a flexible lighting device, in particular of a tubular shape (“light tube”), in a simple, practical manner in space. In particular, the aim here is to achieve an effect that can be designed as freely as possible by means of a "light tube" and to at least partially overcome the limitations of conventional construction methods. A correspondingly improved arrangement with a flexible lighting device that is fixed in space is also to be specified.

According to the invention, this object is achieved by a fastening device having the features of patent claim 1 and/or by an arrangement having the features of patent claim 19 .

[0011] A fastening device for a flexible tubular lighting device with a first and a second end is proposed. In this case, the fastening device is designed for fastening the tubular lighting device at least in each case at the first and the second end. In this case, the fastening device has a first end fastening device for fastening the tubular lighting device to the first end and a second end fastening device for fastening the tubular lighting device to the second end. The fastening device is also set up in such a way that at the first end it is possible to supply the tubular lighting device with electric current for its operation. In addition, the fastening device is designed in such a way that the tubular lighting device can be arranged and fastened in one of the possible, in particular three-dimensional, shapes that can be selected in space.

In addition, an arrangement is proposed comprising such a fastening device and a flexible tubular lighting device with a first and a second end, the tubular lighting device being fixed in space by means of the fastening device, and here in particular following a three-dimensional shape.

One of the ideas on which the invention is based is to use the fastening device to enable a shape-free and preferably three-dimensional design of flexible lighting devices, in particular flexible "light tubes", in space by fastening at least one at the first and the second end of the lighting device is provided and is also taken care of the supply of electricity. In particular, with the help of the freedom to design the shape of the lighting device, limitations as given in conventional designs can be overcome.

[0014] In addition, the fastening device according to the invention enables an aesthetic and practical fastening of a tubular lighting device. The attachment is provided at least at the first and the second end of the lighting device, and thus at defined points of the same, which can have an aesthetic and decorative effect. In addition, the electrical supply of the lighting device is ensured at the same time via the first end. The first and second end attachment devices contribute to the shape-free design of the lighting device, which make it possible to attach the first and second ends in a manner separate from one another, and in this way to the achieved shape and lighting effect of the lighting device, which is both illuminating and decorative can act to influence.

According to the invention, the first end fastening device has a mounting part which can be fastened to the tubular lighting device at the first end. Furthermore, the mounting part can be clamped to an element which is designed in the form of a panel and which can be, for example, a panel component of a ceiling or a wall or another construction. In this way, an expedient, simple and easily detachable fastening is made possible in the region of the first end of the tubular lighting device, for example on the plate component, which can be a component of a false ceiling or drywall. In addition, the clamping fastening with the help of the mounting part enables an advantageously unproblematic supply of electrical energy to the tubular lighting device, for example from the rear area of the intermediate ceiling or drywall, i.e. from the area between the intermediate ceiling and the raw or solid ceiling or drywall and the raw or solid wall.

According to the invention, the mounting part of the first end attachment device has a through-opening, the first end of the tubular lighting device being able to be accommodated at least in sections in at least one region of the through-opening. This enables a reliable and aesthetic coupling of the mounting part with the lighting device.

[0017] Advantageous refinements and developments of the invention result from the further dependent claims and from the description with reference to the figures.

In one embodiment, the mounting part has at least one clamping element which can be moved by means of a mechanism in order to effect the clamping fixation. In particular, the mechanism can be a screw mechanism. Thus, the clamping fixation can be brought about in a targeted and defined manner by an operator. In addition, such a mechanism can also be used, for example, to bring about a suitable setting of the clamping force for reliable fastening.

According to a further embodiment, the clamping element is arm-like or wing-like and is in engagement with a screw element that can be actuated by the operator. The mounting part is also provided with a stop or stops for the clamping element. In this case, the stop or stops limit or limit a pivoting range of the clamping element when it rotates together with the screw element, the clamping element being movable on the stop or one of the stops and simultaneous rotation of the screw element along the axis of the screw element . In this way it is possible to move the clamping element along the screw element in order to effect the clamping fixation of the assembly part, or to loosen the assembly part again if necessary. The provision of a stop or stops for realizing pivotability of the clamping element within a limited angular range together with the rotation of the screw element, preferably within an angular range <360 degrees, advantageously makes it possible to move the clamping element relative to a component of the mounting part on which the screw element is stored, swing out or swing in. Thus, for example, the assembly part can be partially inserted into an opening in a plate-shaped element and then the clamping element can first be swiveled out by rotating the screw element in order to reach behind the plate-shaped element. A further rotation of the screw element can then be carried out in order to cause a movement of the clamping element along the screw element and a clamping fixation of the mounting part on the plate-shaped element. In this case, the clamping element can preferably come into contact with the plate-shaped element from a rear side of the latter. A concealed and unobtrusive clamping attachment in the region of the first end of the tubular lighting device is thus advantageously possible. Especially with a view to the electrical supply at this end, the detachability of the attachment is an additional advantage.

In particular, in a further development, the mounting part can be designed with an overhang which is intended to rest against the element, in particular plate-shaped, for example in an edge region of an opening of the element, in particular plate-shaped, through which the mounting part for fastening the first end is partially passable. In this case, the mounting part can be designed in particular in such a way that the clamping element can be brought into a position by pivoting during rotation of the same together with the screw element, in which the clamping element engages behind the in particular plate-shaped element and in this case in particular the edge of the opening, and the clamping element moves is on a different side of the particular plate-shaped element than the overhang.

In a further development, the assembly part has two or more clamping elements. An even more reliable clamping fixation in the area of the first end is thus achieved.

In particular, the mounting part can have a clamping device, for example a clamping screw, in order to clamp the first end of the tubular lighting device in the through-opening. For example, the through-opening can be designed with a circular cross-section, at least in sections. In one development, a cross section of the through-opening can essentially correspond, at least in sections, to an external cross section of the first end of the tubular lighting device. The tubular lighting device can thus advantageously be coupled to the mounting part in a simple and expedient manner. In addition, the through-opening of the mounting part in particular makes it possible, for example, to lead a power supply line, such as a cable, out of the first end of the tubular lighting device on a rear, covered side of the mounting part.

In a further advantageous embodiment, the second end attachment device is designed for attachment of the tubular lighting device to the second end by means of magnetic force.

In particular, the tubular lighting device can be attached at the second end to a ceiling or a wall or another surface by means of magnetic force. This enables the second end to be attached flexibly and thus advantageously contributes to the variable, shape-free design of the tubular lighting device. For example, the second end can be easily detached and reattached in modified positioning. In this way, the decorative effect of the "light tube" can be varied in a simple and effective way.

In a further development, the second end fastening device has an end piece which is provided at the second end on the tubular lighting device or can be fastened at the second end to the tubular lighting device, as well as an, in particular ferromagnetic and/or magnetized, built-in element which is in particular in the form of strips or plates is on. The built-in element is intended for installation in a coupling area, in particular installation on the surface or near the surface in a ceiling or a wall or another structure. The tubular lighting device can be fastened to the second end in the coupling region by means of the magnetic force effect between the end piece at the second end and the built-in element. Thus, a magnetic attachment is particularly effective, in which, for example, the magnetic coupling along a strip or plate-shaped built-in element that is preferably not visible is made possible and the positioning in the area of this built-in element can be varied in order to change the decorative lighting effect.

In particular, the end piece can have a permanent magnet at the second end.

In an alternative embodiment, the second end attachment device is designed for mechanical attachment and/or for non-magnetically adhesive attachment of the tubular lighting device at the second end. This also enables the second end to be attached in an expedient manner in order to achieve a shape-free design of the light tube. Such attachments can also be implemented in a simple manner. In particular, the tubular lighting device can be attached at the second end to a ceiling or a wall or another surface in a mechanical and/or non-magnetic manner.

In a further development, the second end fastening device can be designed for fastening the tubular lighting device to the second end by screwing or by means of a Velcro connection or by means of an adhesive connection or by means of a pressure difference. For example, screwing can be regarded as a mechanical attachment, the Velcro connection can also be regarded as a mechanical attachment and, when considering the Velcro connection as a whole, also as a non-magnetic attachment, and the adhesive connection and attachment by means of a pressure difference can each also be regarded as a non-magnetic attachment . The attachment by means of a pressure difference can be accomplished, for example, by means of one or more suction cups. Other, different types of attachment can also be considered.

In particular, attachment by means of an adhesive connection, by means of suction cups or by means of a Velcro connection can be advantageous for applications in the home, for example. The Velcro connection also offers an advantage of easy detachment, whereas suction cups can be advantageous for attachment to smooth surfaces.

In a further alternative configuration, the second end fastening device has an end piece which is provided at the second end on the tubular lighting device or can be fastened at the second end to the tubular lighting device and which is attached to an element, in particular a plate-shaped element, for example a plate component of a ceiling

or a wall or other structure that can be clamped. Thus, the advantages of a clamping attachment already explained above can also be achieved for the second end.

In a further development, the end piece of the second end fastening device can have a recess or through-opening, the second end of the tubular lighting device being able to be accommodated at least in sections in at least part of the recess or through-opening. In a further development, the end piece can be equipped with a clamping device, for example a clamping screw, in order to clamp the second end in the recess or through-opening of the end piece. An internal cross section of the recess or the through-opening of the end piece can be circular, for example. In particular, a cross section of the recess or through-opening of the end piece, at least in a section thereof, can essentially correspond to an external cross section of the second end of the tubular lighting device. The tubular lighting device can thus be coupled to the end piece in a simple and expedient manner.

It should be noted that, in embodiments of the invention, different combinations of the configurations of the first and second end attachment devices described above are conceivable and can be advantageous. A clamping fixation in the region of the first end combined with a magnetic fixation in the region of the second end is a preferred combination, although other combinations can also be useful.

In a further embodiment, the fastening device has at least one intermediate fastening device which can be arranged at an arbitrarily selectable point between the first and second end along the tubular lighting device in order to fasten the tubular lighting device at an additional location in space. Fastening at an additional point in space, or at several additional points in space, using one or more intermediate fastening devices makes it possible to design the shapes of the tubular lighting device in space, and in particular three-dimensionally in space, even more specifically and freely. A variety of three-dimensional shapes of the "light tube", not only along ceiling surfaces, wall surfaces or other surfaces, but also, for example, floating in space, is thus even better possible. In this way, for example, special lighting effects can also be achieved.

[0034] In particular, the intermediate fastening devices in different configurations can fix different degrees of freedom of the tubular lighting device in space, and for example different numbers of such degrees of freedom.

In one embodiment, the intermediate attachment device is formed with a ring-like holding component that is designed to enclose the tubular lighting device. A reliable fastening of the tubular lighting device at the additional location is thus achieved.

In one development, an inner diameter of the ring-like retaining component is preferably larger than an outer diameter of the tubular lighting device. This can make it possible to move or displace the tubular lighting device—the “light tube”—in relation to the ring-like holding component, if necessary, for example in the longitudinal direction of the lighting device.

In a further embodiment, the intermediate fastening device is designed with a holding component in the form of a clamp, which is designed to partially enclose the tubular lighting device. In particular, the holding component in the form of a clamp can have two legs which are designed to come into clamping contact with an outer side of the tubular lighting device. In this way, a reliable fastening of the tubular lighting device at the additional location and in particular also a fixation in the longitudinal direction of the lighting device can be achieved.

In addition, it can be made possible that the light emission of the tubular lighting device at the additional location is not interrupted by the holding component, at least in a section of the circumference of the lighting device. In this way, another special aesthetic effect can be achieved.

In one embodiment, the intermediate fastening device is designed for hanging the tubular lighting device from a ceiling or from another structure. The additional location at which the tubular lighting device is held with the aid of the intermediate fastening device can therefore be within the room—remote from the ceiling and/or wall—which makes a free three-dimensional design of the tubular lighting device even easier.

In a further embodiment, the intermediate fastening device is designed with a component or assembly that can be fastened in a mechanically and/or non-magnetically adhesive manner in a mounting area. The mounting area can be provided, for example, in the area of a wall or a ceiling or another surface or on another structure. In this way, the tubular lighting device can be attached in different directions, for example firmly relative to the mounting area, which in turn can advantageously contribute to fixing a selected three-dimensional shape of the "light tube".

In further developments, the intermediate fastening device can be formed with a component or assembly that can be fastened in a mounting area by screwing or by means of a Velcro connection or by means of an adhesive connection or by means of a pressure difference. With regard to these types of attachment and their advantages, reference is made to the above statements on the second end attachment device. The advantages mentioned above can also be achieved analogously with regard to the intermediate fastening device. Additional, other types of attachment can also be considered.

[0041] According to a further embodiment, the intermediate fastening device is set up to enable the tubular lighting device to be fastened to the additional location by coupling a component or assembly of the intermediate fastening device in a mounting area by means of magnetic force. The mounting area can in turn be provided in the area of a ceiling or wall or another surface or on another structure. Fastening by means of magnetic force is advantageous, especially since it can be designed in such a way that it can be easily detached. Also, the location of attachment can be varied without leaving visible traces in the mounting area.

In a further development, the intermediate fastening device can have an in particular ferromagnetic and/or magnetized built-in element, which is in particular in the form of strips or plates, the built-in element being suitable for in particular superficial or near-surface installation in the assembly area, in particular in a Ceiling or a wall or other construction is provided. In this case, the tubular lighting device can be fastened at the additional location by means of a magnetic force effect between the component or assembly and the built-in element. In this regard, too, reference can be made to the advantages already explained above in connection with the second end attachment device, it being possible for the stated advantages to be achieved analogously with regard to the intermediate attachment device.

In particular, the component or subassembly of the intermediate fastening device, which can, for example, interact magnetically with the built-in element, can have a permanent magnet.

[0044]In further developments, intermediate attachment devices corresponding to the configurations explained above can be combined with the first and second end attachment devices described above in a variety of arbitrary ways and in a wide variety of numbers.

In a further embodiment, the fastening device for fastening a

tubular lighting device set up with a length of up to about 10 meters. However, other lengths of the tubular lighting device, which can also be referred to as a light tube, are also conceivable.

The aforementioned, in particular ferromagnetic and/or magnetized/magnetizable, built-in elements can each be configured in particular as a metal plate or as a metal strip. This thus enables the magnetic attachment of the mounting part or end piece or the component or assembly mentioned in each case, for example under the action of the permanent magnet.

[0047] In configurations, the built-in elements can each be designed in the most varied of shapes and sizes. For example, the built-in element can be designed as a straight or curved strip, respectively, or instead as a polygonal or round plate.

In particular, it can be provided that the tubular lighting device has a substantially constant cross section along its length, in particular a substantially constant round cross section, for example a circular cross section.

[0049] The above configurations and developments can be combined with one another as desired, insofar as this makes sense. Further possible refinements, developments and implementations of the invention also include combinations of features of the invention described above 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.

It should also be noted that the configurations and developments described above in connection with the fastening device can be applied equally to the arrangement according to the invention.

DESCRIPTION OF EXEMPLARY EMBODIMENTS

1 shows an arrangement 100 which is used to illuminate an interior space in a building and at the same time to produce a decorative, aesthetic light effect. The interior has walls 17 and a false ceiling 16 . The ceiling 16 can be designed, for example, as a construction with panel-shaped elements, such as a suspended plasterboard construction. The walls 17 can be solid or can also be constructed in front of a solid wall with panel-shaped elements, such as plasterboard.

ten construction, to be formed.

The arrangement 100 comprises a flexible, tubular lighting device 1, which can also be referred to as a “light tube” 1. The “light tube” 1 can, for example, have LEDs for light generation in its interior, with other devices for light generation being conceivable.

The lighting device 1 is arranged in space in a three-dimensional shape, following a curve running in three-dimensional space, the flexibility of the light tube 1 allowing a very large number of possibilities for arranging and shaping the light tube 1 . The flexible tubular lighting device 1 can be several meters long, for example up to about 10 meters long. Shorter or longer lengths are also conceivable. In a preferred example, the cross section of the lighting device 1 is constant and round along the entire length, for example circular.

The arrangement 100 of FIG. 1 also includes a fastening device, by means of which the lighting device 1 is fastened in space, following the form described. The fastening device provides a number of fastening options which at least enable the tubular lighting device 1 to be fastened to a first end 3 of the lighting device 1 and to a second end 4 of the lighting device 1 . The interaction of the fastening options provided by the fastening device makes it possible to arrange and fasten the flexible light tube 1 three-dimensionally in one of the possible shapes that can be selected, in other words “shape-free”. For this purpose, a plurality of fastening devices are provided, the combination and arrangement of which, which can be selected by the user or the lighting designer, enables the course of the light tube 1 to be designed flexibly and freely.

An arrangement 200 according to a second exemplary embodiment with a plurality of flexible, tubular lighting devices 1 and fastening devices, by means of which the lighting devices 1 are each fastened in space, is shown in FIG.

The fastening device, as used in the arrangements 100, 200 by way of example, will be described in more detail below.

3 again shows a flexible tubular lighting device 1 with a first end 3 and a second end 4. The fastening device comprises a first end fastening device 6 for fastening the lighting device 1 to the first end 3 and a second end fastening device 36 for fastening the lighting device 1 at the second end 4.

The lighting device 1 is supplied with electric current for its operation in the region of the first end 3 by means of a supply line 5 which is designed, for example, as a cable. Other devices that serve to supply the lighting device 1 with electrical energy by means of the cable 5 are not shown in detail in the figures. It goes without saying, however, that further devices known per se to the person skilled in the art for enabling, switching and/or controlling the supply of the lighting device with electrical current, a converter, a transformer or similar devices can be provided.

The first end attachment device 6 has a mounting part 10 which is attached to the first end 3 of the lighting device 1 . The mounting part 10 enables a firm, clamping fixation and thus attachment of the lighting device 1 in the area of its first end 3 to a plate-shaped element 15, see FIG. However, the plate-shaped element 15 is not necessarily part of a ceiling 16, but can be part of a wall 17 or other structure.

The mounting part 10 has a base component 11 on which two screw elements 28 are rotatably mounted, see FIGS. 4 to 7. A longitudinal axis 10a of the mounting part 10 essentially falls

sentlichen with the longitudinal axis of the tubular lighting device 1 at the first end 3, to which the mounting part 10 is attached together. Longitudinal axes 28a of the screw elements 28 are arranged offset radially with respect to the axis 10a relative to the axis 10a, however, in the exemplary embodiment shown, they are each arranged to run parallel to the axis 10a.

The mounting part 10 also has two clamping elements 21, which are each arm-like or wing-like, see FIGS. 4, 6 and 7. Each of the clamping elements 21 is in engagement with an associated one of the screw elements 28, for which each of the clamping elements 21 has a Section 23 may have an internal thread into which an external thread of the screw element 28 engages.

The mounting part 10 also includes a cover element 12, see in particular Figs. 4 and 5, the cover element being designed in such a way that, when the mounting part 10 is installed, it is on a visible side S of the plate-shaped element 15, and thus one of the Spatiality facing and outside substantially cylindrical portion 11d and a part of a plate-like supernatant 11a of the base member 11 accommodates itself. The base component 11 is thus covered on the visible side S by the covering element 12 . For this purpose, the cover element 12 has an inner, central, step-like through-opening 13, the inner dimensions of which at a distal end of the cover element 12, viewed in relation to the plate-shaped element 15 in the installed state, essentially correspond to an outer cross-section of the light tube 1 and at one end in relation to the plate-shaped Element 15, seen in the installed state, corresponds to the outer contour of the section 11d and the overhang 11a at the proximal end of the covering element 12. On an outer side that is visible in the assembled state, the cover element 12 has a tapering, rotationally symmetrical contour 14 that is curved in the longitudinal section of FIG. 5 .

FIG. 5 also shows that the first end 3 of the tubular lighting device 1 is guided through the through-opening 13 of the cover element 12 and through a likewise central through-opening 9 in the base component 11 . The inner cross-section of the through-opening 9, which extends through the section 11d, also essentially corresponds to an outer cross-section of the first end 3 of the lighting device 1 Element 15 are brought out. The first end 3 of the tubular lighting device 1 is clamped in the through-opening 9 for fastening by means of clamping devices, with the clamping devices in the example in FIG. 5 being one or more clamping screws 8, which in FIG. 5 are designed as grub screws or threaded pins , acts. The clamping screws 8 are provided in the area of the portion 11d and are therefore accessible in the absence of the cover element 12. The screw elements 28 are also accessible from the visible side S for their actuation, for example using a screwdriver, as long as the cover element 12 has not been put on (FIG. 6).

When mounting the first end 3 of the light tube 1, the mounting part 10 can be passed with a rear section 11b of the base component 11 through an opening, for example round, in the plate-shaped element 15 in such a way that the supply line 5 and the clamping elements 21 on the rear side, ie the non-visible side opposite the visible side S, of the plate-shaped element 15 . In this state, without the cover element 12, the screw elements 28 are accessible. The first end 3 of the light tube 1 has already been fixed to the mounting part 10 by clamping using the clamping screws 8 . In order to fasten the mounting part 10 and thus the first end 3 of the lighting device 1 to the plate component 15, the screw elements 28 can be actuated by an operator. 6 shows the engagement geometry of the screw elements 28. A screw mechanism is thus provided, by means of which the clamping elements 21 can each be moved in order to bring about the clamping fixation on the plate component 15.

For inserting the rear portion 11b of the base member 11 together with the clamping members 21 through the opening in the plate-shaped member 15 are the

Clamping elements 21 are each in a position in which they are pivoted relative to the position shown in FIGS. This position of the clamping elements 21, which is not shown in the figures, corresponds to a basic position in which the elements 21 do not protrude beyond the round, plate-like overhang 11a, viewed radially in relation to the axis 10a, but are pivoted inwards as far as possible, viewed radially, and thereby relative to the Edge of the supernatant 11a are set back radially.

After inserting the section 11b of the base component 11 together with the clamping elements 21 into the already mentioned opening in the plate-shaped element 15, the operator can turn each of the screw elements 28 from the visible side S, see Fig. 6, each of the clamping elements 21 pivot within an angular range about a longitudinal axis 28a of the associated screw element 28, as a result of which the clamping elements 21 each protrude outwards beyond an edge of the overhang 11a. In this way, the clamping elements 21 can each reach behind an edge of the plate-shaped element 15 from its rear side.

A further rotation of each screw element 28 by the operator causes the clamping element 21 assigned to the screw element 28 to move in the direction of the arrow 22, see Fig the clamping element 21 to clamp. In this way, the first end 3 of the light tube 1 is fixed to the plate-shaped element 15 , with the projection 11 a and the clamping elements 21 being in contact with the element 15 .

It is clearly shown, in particular in FIG. In a first end position, not shown in Fig. 7, the clamping element 21 rests against the stop 31 with a first side of the clamping element 21 and does not protrude beyond the projection 11a, but is pivoted inwards as far as possible to facilitate insertion of the Section 11b to be able to insert through an opening which is smaller than the outer diameter of the supernatant 11a. In a second end position, shown in Fig. 7, the clamping element 21 rests against the stop 31 with a second side in a further area of the latter, as a result of which further rotation of the clamping element 21 with the screw element 28 is prevented and instead with further rotation of the screw element 28 and simultaneously abutting against the stop 31, the clamping element 21 moves along the axis 28a along the screw element 28 in direction 22 in order to effect the clamping.

8 to 10 show a variant of a first end attachment device 6°, which can alternatively be used in the arrangement 100 or 200, for example designed tubular lighting device 1 and represents a variant of the first end attachment device 6. The differences of the first end attachment device 6 'relative to the first end attachment device 6 will be described below, with reference to the above explanations.

A cover element on the visible side S is not shown in FIGS. 8-10, but it is understood that one can be provided.

The first end attachment device 6' also has a base component 11° on which two screw elements 28' are mounted. Analogously to the example of FIGS. 3-7, longitudinal axes 28a' of each of the screw elements 28 run essentially parallel to and offset from a longitudinal axis 10a' of the end attachment device 6'.

The first end 3 of the lighting device 1 can be clamped by means of clamping screws 8' in the end attachment device 6' in a central passage opening 9', the inner cross section of which essentially corresponds in sections to the outer cross section of the first end 3 of the light tube 1. See, for example, Fig. 10.

In the variant according to FIGS. 8 to 10, however, the clamping screws 8' are after insertion

of the base part 11' into an opening in the plate-shaped element 15 from the visible side S are no longer accessible, but are located in the installed state of the base component 11° on a rear side of the element 15 opposite the visible side S. During assembly, first the base component 11° is clamped to the light tube 1 by means of the clamping screws 8' and thus coupled, after which a rear section 11b' of the base component 11' can be inserted into the opening in the plate-shaped element 15. In this state, the clamping elements 21', which in the variant of FIGS. 8-10 are also arm-like or wing-like, are in their pivoted-in state, as shown in FIG Supernatant 11a 'not out, but are set back relative to this.

The clamping elements 21' and stops 31a', 31b' are designed in the first end attachment device 6' as described below.

Each clamping element 21' has a section 23° which is formed with an internal thread. The internal thread of section 23' is engaged with the external thread of screw element 28°'. In the state of FIG. 9, in which each clamping element 21' is in its pivoted-in state, a section of the clamping element 21' that is distal from the section 23' rests against the stop surface 31b'. By rotating the screw element 28', the clamping element 21' can be moved away from the projection 11a', while it continues to rest against the stop 31b'. Here, the clamping element 21' can thus move counter to the direction of the arrow 22' (FIG. 8) along the screw element 28'. In this way it can be achieved, for example, that the clamping element 21' is sufficiently far away from the overhang 11a' to engage behind a plate-shaped element 15 of a given thickness. This movement can be carried out, for example, before or after the rear section 11b' of the base component 11' is inserted through the opening in the plate-shaped element 15, or the clamping element 21' can already be in the uppermost possible position on delivery or in an intermediate position, for example on the half of the free length of the screw element 28' or similar.

In order to clamp the base component 11° and the mounting part 10° to the plate-shaped element 15, the screw element 28' is then rotated in the opposite direction by the operator, for example using a screwdriver as before, see the accessible screw heads in Fig. 8. Here, the clamping element 21' pivots, see the arrow 24' in FIG. 9, about the axis 28a' beyond the overhang 11a'. The second stop 31a' limits the pivoting range of the clamping element 21' to an angular range of <180 degrees. When the clamping element 21' then rests against the stop 31a' with a surface section adjacent to the section 23°, the clamping element 21' moves along the screw element as the screw element 28' rotates further in the direction that led to the rotation 24' 28' in the direction of the plate element 15, in the direction of the arrow 22', see Fig. 8. In this way, analogous to the example in Figures 3-7, the mounting part 10' can be clamped to the plate-shaped element 15 and the first end 3 can thus be fastened.

On one of the supernatant 11a 'and the plate-shaped element 15 side facing, see the example of Figs Section 23' is engaged, and the extension 25' creates an undercut. This can contribute to achieving reliable clamping even with relatively thin plate-shaped elements 15 . In addition, see Fig. 9, if desired, locking of the clamping element 21' against unintentional pivoting out can be achieved in the lowest possible position of the clamping element 21', i.e. in its position which is closest to the overhang 11a'. For this purpose, the base component 11' can be provided with a flat elevation 26° protruding from the overhang 11a' in the longitudinal direction 10a', behind which the extension 25' can engage, for example in a delivery state, when the clamping element 21° on the stop 31b ' pending.

For the sake of completeness, it should be pointed out that both in the first end fastening device 6 and in the first end fastening device 6', the clamping element

elements 21 or 21% are each of the same design and are arranged and operable in the same way.

The end attachment device 6 'of Fig. 8-10 not only allows the first end 3 of the light tube 1 to be firmly clamped to the plate-shaped element 15 and thus the attachment to the ceiling 16 - or the wall 17 -, but also the Power supply of the lighting device 1 at the first end 3. For example, see Fig. 8-10, the through-opening 9' with a smaller diameter can continue in a section 9a' along the longitudinal axis 10a' of the mounting part 10', so that through section 9a 'The through-opening 9', the cable 5 (not shown in Fig. 8-10) can be led out.

In particular in the variant of FIGS. 8-10, the rear section 11b' of the base component 11' partially forms a surface 11c' as an outer surface, which is formed as a section of a cylinder surface. In the pivoted-in state of FIG. 9, the outside of the pivoted-in clamping element 21' can be B. also form at least approximately a portion of this cylinder surface. In this way, the base component 11' with the clamping elements 21' swiveled in can be easily guided through a circular opening in the plate-shaped element 15, the diameter of which essentially corresponds to the diameter of that cylinder which defines the shape of the surface 11c', or is slightly larger. The projection 11a' protrudes radially outward beyond the surface 11c' in such a way that clamping by means of the clamping elements 21' can take place against the projection 11a'.

In an example presented for illustration, it can be provided in a further variant of the first end attachment device that the attachment of the tubular lighting device 1 in space at the first end 3 is not made possible by clamping on the element 15 but by means of magnetic force. A first end attachment device 6", which can be used in other examples in the arrangements 100 or 200, is shown schematically by way of example in Fig. 11. Here, a mounting part 10" of the end attachment device 6" is, for example, equipped with a ferromagnetic and/or magnetized element 7 ", for example a permanent magnet. In the example in FIG. 11, a built-in component 99 is built into the plate-shaped element 15, which forms the ceiling 16 or wall 17, in such a way that it is not visible from the visible side S.

In the case of the first end fastening device 6", the first end 3 of the light tube 1 can be held and fastened to the plate-shaped element 15 by means of magnetic force action between the element 7" and the component 99.

For this purpose, the built-in component 99 can have a ferromagnetic and/or magnetized built-in element, for example in the form of a plate or strip.

In addition, the built-in component 99 can be designed as an induction device for supplying the tubular lighting device 1 with electrical energy inductively. A device 99a in the mounting part 10" enables the transmission of electrical energy without a continuous line to the tubular lighting device 1 by interacting with the built-in component 99. The component 99 can in turn be supplied via a line 5. Such a first end attachment device 6" can also allow the positioning of the first end 3 to be easily varied.

Although the above-described examples of the first end attachment device 6, 6°, 6″ are advantageous, in further variants presented here for illustration, the mounting part could also be attached to the plate-shaped element 15 by screwing.

Reference is again made to FIGS. 1 and 2, which also show the second end 4 and the second end fastening device 36 provided in the region of the second end 4. FIG. The latter is used to attach the light tube 1 to the second end 4 and will be described below.

In a preferred variant, the second end attachment device 36 is for a loading

strengthen the tubular lighting device 1 formed at the second end 4 by means of magnetic force. This is shown schematically in FIG.

The second end attachment device 36 has an end piece 40 which can be attached to the second end 4 of the lighting device 1 . Furthermore, the second end attachment device 36 has a ferromagnetic and/or magnetized built-in element 42 designed as a rather elongated plate or strip, which is built into the wall 17 close to the surface, for example in a plate-shaped element 15 with which the wall 17 is formed. For example, the mounting element 42 may be a metal strip which may be installed anywhere in the wall 17, or in the ceiling 16 or other structure, to provide magnetic attachment of the end piece within the extent of the element 42 40 and thus the second end 4 of the light tube 1 to allow. This is shown for the wall 17 in FIG. 1 as an example.

The detailed configuration of the end piece 40 is to be discussed again in more detail below. The light tube 1 can thus be fastened at the second end 4 in a coupling area 44 by means of the magnetic force effect between the end piece 40 and the built-in element 42 .

In a further variant, it can also be provided that the second end fastening device 36 can be fastened to a plate-shaped element 15 by clamping, analogously to the end fastening device 6, 6'. In particular, when the light tube 1 is supplied with electric power via the first end 3 , such a power supply is not required at the second end 4 . An end piece designed analogously to the assembly part 10, 10' can thus be provided as the second end attachment device 36.

[00117] Further variants of the fastening device, which can enable the fastening of the tubular lighting device 1 in the arrangements 100, 200, are shown in FIGS.

Fig. 12 shows a mechanical attachment of the second end 4 of the tubular lighting device 1, e.g. to a wall 17 or the ceiling 16 by screwing, the end piece 40a being provided, for example, with a base part designed for attachment by screwing and a cover element in the Substantially analogous to the cover 12 of Figs. 3-7 can be formed.

Purely by way of example and schematically, two screws 41a are indicated in FIG.

Another variant is shown in FIG. An end piece 40b is provided at the second end 4, which is designed for fastening the second end 4 of the light tube 1 to the wall 17, or alternatively, for example to the ceiling 16, by means of a Velcro connection. 13 shows hook and loop fastener elements 41b, whereby the hook and loop fastener element 41b fastened, for example glued, to the wall 17 can be larger than the element 41b provided on the end piece 40b, in order to allow a variation in the positioning of the end 4.

In a further variant, shown in FIG. 14, an end piece 40c can be fastened to the second end 4 of the light tube 1, which also enables non-magnetic adhesion for fastening the lighting device 1 to the second end 4. The end piece 40c has suction cups 41c. The suction cups 41c allow the second end 4 to be attached to a particularly smooth surface, for example to the wall 17 or to the ceiling 16. For example, attachment to a smooth glass, ceramic or stone surface can be considered. The attachment by means of the suction cups 41c takes place by means of negative pressure, i. H. a pressure difference between the ambient pressure and the volume enclosed by the suction cup.

In yet another variant, see FIG. 15, an end piece 40d is attached to the second end 4, the end piece 40d being formed with an adhesive surface 41d. Thus, the light tube 1 can be attached at the second end 4 by means of an adhesive connection, for example to the wall 17,

or the ceiling 16, are attached.

Coming back to FIGS. 1 and 2, the fastening device in each of the arrangements 100, 200 also has intermediate fastening devices, which are used to fasten the light tube 1 at other points in space, which further expands the possibilities for shaping the light tube 1.

Some examples of intermediate fasteners 46a-46g are shown schematically in Figures 1, 2, and 16-22. Each of the intermediate attachment devices 46a-g can be arranged at an arbitrarily selectable free location between the first end 3 and the second end 4 of the lighting device 1 in order to hold the lighting device 1 at an additional location Z1 to Z9 and thus at this location additionally to be fixed.

Examples of the intermediate fasteners 46a-46g are described in more detail below. Depending on the configuration, the intermediate fastening devices fix different degrees of freedom of the light tube 1 at one point of the same.

The intermediate attachment device 46a comprises a ring-like retaining component 50 at the end of a cable 51. The ring-like holding component 50 completely encloses the tube-like lighting device 1 along its circumferential direction, with an inner diameter of the ring-like holding component 50 being larger than the outer diameter of the light tube 1 in the example in FIGS. 1, 16 and 17. In this way, the ring-like holding component 50 does not lie peripherally closely to the light tube 1, but loosely surrounds the light tube 1 in such a way that the light tube 1 rests only in a lower region of the ring-like holding component 50, seen in the vertical direction, on the inner circumference of the holding component 50. This can be seen, for example, in Figure 16, which shows a variant 46f of the intermediate attachment means 46a. A movement of the light tube 1 in its longitudinal direction relative to the holding component 50 and a twisting therein relative to this are thus easily possible.

The intermediate fastening device 46a and its variant 46f in FIG. 16 are also designed for hanging the tubular lighting device 1 from the ceiling 16, or alternatively from another construction. In this way, the lighting device 1 is held at the further point Z1 or Z9 in space (see FIGS. 1, 16), a lateral movement normal to the direction of the cable 51 remaining possible.

The intermediate attachment device 46a is adapted to enable the attachment of the light tube 1 to the additional location Z1 by coupling an assembly 78 in a mounting area 85 on the ceiling 16 by means of magnetic force.

For this purpose, the intermediate fastening device 46a has a ferromagnetic and/or magnetized built-in element 91 which, in the example in FIG . Fig. 17 shows schematically the mounting element 91, such as a plate made of ferromagnetic metal, e.g. iron, and the assembly 78.

The assembly 78, see Fig. 18, includes a base member 79, a round, disc-shaped permanent magnet 80 with a central through hole, a screw 81 and a cover member 82. The base member 79 is formed substantially rotationally symmetrical, is set up with to be coupled to the cable 51 and is formed in a tapered shape along its longitudinal axis. In the area of the wider end of the base element 79, this has an essentially circular, flat recess which is designed to accommodate the permanent magnet 80 therein. The permanent magnet 80 can be fastened to the base element 79 by means of the screw 81, the last-mentioned recess of which has a central opening, e.g. with a thread, for screwing in the screw 81.

By means of magnetic force between the permanent magnet 80 and the built-in element 91, the lighting device 1 can be attached to the additional location Z1. FIG. 17 shows that the cover member 82 covers the central portion of the permanent magnet 80 and the screw 81. FIG. For example, element 82 could be on permanent magnet 80

be glued on. The element 82 could be formed from a similar material to the base element 79, or the cover element 82 could be made soft in order to protect the mounting area 85 during magnetic coupling and repositioning if necessary.

On the other hand, the intermediate attachment means 46f of FIG. 16 is formed with an assembly 64 connected to the cable 51, the assembly 64 being mechanically fixed to the ceiling 16 in a mounting area 70. FIG.

Here, the assembly 64 is fastened in the mounting area 70 in particular by screwing on the component 64 by means of fastening screws that are not shown in detail.

The intermediate fastening device 46c of FIG. 19 has a holding component 55 in the form of a clamp, the holding component 55 being set up not to completely but only along part of the circumference of the light tube 1. Thus, the light emission effect of the light tube 1 in the area of the clamp 55 is not interrupted along the entire circumference of the light tube 1, which in turn achieves a different optical effect.

The intermediate attachment means 46c, see also Fig. 1, can be used for attachment at the additional locations Z2 to Z5 with only the clamp-shaped retaining component 55 and an associated attachment screw (not shown in the figures) for mechanically attaching the clamp 55 (" Clip") on the ceiling 16 - or the wall 17 - be formed. In the central region of the light tube 1 of FIG. 1, this enables, for example, attachment with relatively small distances between points Z2 to Z5 in a comparatively inconspicuous manner and with the light tube 1 being guided close to the ceiling.

The holding component 55 designed in the form of a clamp has two legs 60 arranged essentially symmetrically to one another, which are shaped, for example, in the shape of a circular arc segment and are designed to come into clamping contact with their inside with an outside of the tubular lighting device. The two legs 60 each have a curved cross section in such a way that they are adapted to the round cross-sectional shape of the tubular lighting device 1 and are each connected to one another in one piece on one side by means of an intermediate section 61 . The intermediate portion 61 is straight in cross-section and has a centrally located through opening 62 through which, for example, a screw for fastening the component 55, as shown for the intermediate fastening means 46c in FIG. 1, can be passed.

Fig. 20 shows a variant in which a holding component 55 corresponding to Fig. 19 is connected via a cable 51 to an assembly 64 in order to form an intermediate attachment device 46d which allows the tubular lighting device 1 to be suspended at an additional location in space from the ceiling 16 or other structure. In this case, the cable 51 can, for example, be guided through the through-opening 62 and provided with a thickening at the end that is guided through, in order to establish the connection with the clamp 55 .

Analogously to the intermediate fastening device 46f shown in FIG. 16, the subassembly 64 can be fastened to the ceiling 16 by screwing.

A variant of the intermediate attachment device 46d is shown in FIG. 2 with the intermediate attachment device 46g. In Fig. 2, the cable 51, which is connected at one end to a clamp-like holding component 57, which is preferably designed analogously to the holding component 55, is connected at the other end of the cable to a component 65, which in turn is mechanically attached to the ceiling in the mounting area 70 fastened, e.g. screwed into it.

1 shows yet another variant 46b of an intermediate fastening device. The intermediate fastening device 46b is also used to hang the tubular lighting device 1 from the ceiling 16, and for this purpose has two assemblies 64 fastened mechanically to the ceiling 16 by screwing in the mounting area 70. A cable 51 is connected to each assembly 64, the cables 51 being connected at their other ends to an associated end of an elongate support component 56, respectively. The holding component

56 is designed in the manner of a continuous profile, within which the light tube 1 runs, for example, in a straight line. A varied effect can thus be achieved again. While the holding component 56 is essentially closed on the rear side 56a, the holding component 56 is open on its front side 56b opposite the side 56a, so that the light tube 1 shines out there.

Preferably, the retaining component 56 is formed with a cross section corresponding to that of the retaining component 55 of FIG. 19, however, the retaining component 56 is much longer than the component 55. For example, the holding component 55 can be a short section, while the holding component 56 can be a significantly longer section, of an otherwise identical profile, in which the through-opening(s) 62 for the connection, e.g / The ropes 51 are introduced.

Another variant of an intermediate attachment device 46e is shown in FIGS. 21 and 22. The holding component 55 of FIG. 19 is also used here, this being combined with an assembly 78' for magnetic attachment in FIGS. 21 and 22.

The assembly 78' includes a base member 79°, a permanent magnet 80 and a screw 81. As with the assembly 78 of FIG. The base element 79' is designed essentially analogously to the base element 79, but is designed in the area of the tapered end of the base element 79' for screwing in a screw 58, by means of which the holding component 55 can be fastened to the base element 79'.

21 and 22 do not show a cover element 82 for the assembly 78', although it goes without saying that a cover element 82, as described for FIG. 18, could be provided analogously to the example in FIG.

By means of the intermediate fastening device 46e, the tubular lighting device 1 can be fastened at an additional location by coupling the assembly 78' in the mounting area 85 by means of magnetic force, for example by means of a magnetic force effect between the permanent magnet 80 and the built-in element 91. The built-in element 91 can, as shown in Fig 1 may be incorporated, or may be provided at any other location of the ceiling 16 or a wall 17.

It should also be pointed out that the other mechanical and/or non-magnetically adhesive connections, as described by way of example for the second end attachment device with reference to FIGS by suction cups, or by gluing, are also applicable to intermediate fasteners 46a-g. In particular, the subassembly 78 or the subassembly 78' can be designed for a Velcro connection analogous to Fig. 13 or for a connection by means of a vacuum analogous to Fig. 14 or for an adhesive connection analogous to Fig. 15, it being understood that the permanent magnet 80 omitted and the base element 79 or 79 'can be modified accordingly.

In addition, it should be noted, again with reference to FIGS. 1 and 3, that the second end attachment device 36, as shown in FIG of the light tube 1 in the area 44 is made possible by the magnetic force between the built-in element 42 and the permanent magnet 80 . Here, the end piece 40 is provided with a recess corresponding to FIG. If necessary, a cover element 82 can also be provided. The end piece 40 can, for example, have a base component 40' with two parts, an inner part and a cover element, the inner part being equipped with the recess for the permanent magnet 80 and also with a recess or through-opening approximately analogous to FIG of the second end 4 of the light tube 1 can be formed. A schematic representation is shown in FIG. 23, with a clamping screw 8'' for clamping the second end 4 on the inner part also being represented schematically.

is.

In the arrangement of FIG. 1, the fastening devices 6 and 36 and the intermediate fastening devices 46a, 46b and 46c are used by way of example. Seen from left to right in Fig. 1, to fasten and shape the light tube 1 by means of the first end fastening device 6, mechanical clamping is required along with a power supply at the first end 3 and thus complete fixing at this end, then a magnetically fastened cable suspension with a ring-like Holding component 50, also "clips" 55 mechanically fastened by screwing to the ceiling 16 for fastening the light tube 1 to the ceiling in a section thereof, a cable suspension mechanically fastened to the ceiling 16 by screwing with the aid of the two assemblies 64, which the continuous, long "clip ” 56, and at the second end 4 on the wall 17 a magnetic “end cap” in the form of the end piece 40 of the second end attachment device 36 is provided.

In the exemplary embodiments and variants described above, the built-in elements 42, 91, 99 can be designed in a wide variety of shapes and sizes. A built-in element 42, 91 or 99 in the form of a straight strip or a rectangular or round plate may be advantageous, but is not absolutely necessary. Alternatively, the mounting member 42, 91, or 99 could be formed as a strip that follows an arc or other curve.

Furthermore, it is not absolutely necessary to use a built-in element 42 or 91, although this may be advantageous. For example, there could be suitable metallic elements, for example rail- or plate-like elements, which form part of the furnishing of the building interior or the wall or ceiling construction, on which a magnetic coupling by means of the permanent magnet 80 of the end attachment device 36 or one of the intermediate attachment devices, for example 46a, 46e, is possible.

The variants of the first and second end attachment devices as well as the intermediate attachment devices described above can be combined in a wide variety of ways in order to make any of the large variety of possible three-dimensional shapes that the tubular lighting device 1 can assume in space possible. In addition, a variability of this form is also possible, in particular by means of the magnetic attachment or coupling variants that have been described above in relation to the end and intermediate attachment devices.

Although the invention has been fully described above with reference to preferred exemplary embodiments, it is not limited thereto but can be modified in many different ways.

[00153] In particular, the fastening of the light tube is not limited to a ceiling and/or wall. The first and second end attachment device as well as the intermediate attachment device(s) could each serve to enable attachment of the light hose to a floor area. For example, the light tube could be guided from the ceiling over the wall to the floor using the fastening device.
