Description

The invention relates to a fastening device for fastening a light to a ceiling or wall with a fastened to a ceiling or wall, stationary base support and a light mounted or fixed to a light part.

Furthermore, the invention also relates to a use of a fastening device according to the invention.

Fastening devices of the aforementioned or comparable type are for example from the publications DE 10 2013 106 411 A1 . WO 2003/044906 A1 . CN 104 456 446 A such as US 2017/0 167 707 A1 previously known.

Heretofore, it has been customary to attach lights to a ceiling to a ceiling or wall by means of a hook which is fixed to a wall or ceiling as a base support and to a ceiling or wall by means of a corresponding counter hook or eyelet provided on the light side. As soon as the base support is attached to the wall or ceiling, the electrical connection cables on the wall or ceiling are connected to the luminaire. This usually luster terminals are used. If the luminaire is connected to the electrical connection line, the luminaire can be fastened to the basic support with its eyelet or the counter hook.

Especially in suspended luminaires, the electrical connection of the luminaire to the ceiling can be connected with comparatively much overhead work at the attachment point.

The object of the invention is therefore to provide a fastening device of the type mentioned, which simplifies the installation and replacement of lights on a ceiling or wall.

To solve this problem, the means and features of the independent, directed to a fastening device claim are proposed in a fastening device of the type mentioned. In particular, therefore, a fastening device of the type mentioned is proposed, which has a mounting coupling for releasably connecting or attaching the luminaire portion with or on the base support, wherein the mounting coupling a disposed on the base support coupling element and, in particular rotationally fixed, connected to the luminaire part, to the Complementary trained counter-coupling element, wherein the coupling element is rotatable in coupled with the counter-coupling element position of use together with the luminaire portion relative to the base support and wherein the coupling element relative to the base carrier axially displaceable and a rotary ring with at least two holding projections or receptacles and the counter-coupling element respectively has matching holding receptacles or projections.

The luminous part and the counter-coupling element can in this case be present as a materially homogeneous, monolithic unit and in this way rotatably connected to each other. The luminaire part and the counter-coupling element can therefore be integrally connected.

With the aid of the fastening coupling of the fastening device, the luminaire part, which is suitably designed for the basic carrier, can thus be fixed with its counter-coupling element to the basic carrier. The installation of the lamp can be done with less effort and comfortable.

In order to mount the lamp to be mounted in the desired orientation, it may be necessary in the previously known fastening devices to remove the lamp again from the base support and attach the base support in a changed orientation on the wall or ceiling. All work for mounting and connecting the luminaire to the ceiling or wall must then be carried out again. Is an exchange of a mounted lamp desired, this is also associated with a certain assembly effort.

To avoid these problems, it may therefore be advantageous if the coupling element is rotatable with closed coupling coupling in coupled with the counter-coupling element use position together with the light part relative to the base support, the counter-coupling element can then preferably be rotatably connected to the light part.

Thus, it is then possible with the fastening device to align an already suspended or mounted light by the rotation of the coupling element relative to the base support even in the mounted position of use. This is particularly advantageous for elongated suspension lamps. With such elongated suspension lamps, even smaller angular deviations of the mounted luminaire from its desired target orientation are easily noticed and perceived as disturbing.

The fastening device provides a remedy to this effect in that a fine adjustment and / or a reorientation of a light fastened in this way is possible with the aid of the fastening device without dismantling the base support or the light.

It may be particularly advantageous if the mounting coupling is tool-free closable and detachable. In this way, the mounting coupling of the fastening device for replacement of a lamp, for example, can be solved purely manually and without the use of tools. This can increase the flexibility of the fastening device and its handling.

In order to promote a rotatability of the coupling element relative to the base support, the coupling element according to the invention is axially displaceable relative to the base support. By an axial displacement of the coupling element relative to the base support a frictional connection between the coupling element and the base support can be repealed to make alignment of a mounted light by rotating the light part together with the coupling element even with the fastening coupling closed.

In order to promote a release or opening of the mounting coupling without tools, it may also be advantageous if the coupling element, in particular on its wall or ceiling side top, has an anti-slip coating and / or consists of an anti-slip material. In this way it is possible to press the coupling element when releasing or opening the fastening coupling by pressing the luminaire part against the wall or ceiling and the required relative to the release coupling relative movement between the coupling element and the counter-coupling element by a corresponding release or opening movement to be separated from the coupling element. In this case, the coupling element can be retained on the wall or ceiling due to its slip-resistant coating or due to the slip-resistant material, so that the mounting coupling can be solved easily.

The fastening device can also have an electrical contacting device for establishing an electrical connection between a lamp connected to the luminaire part and an electrical connection. It can be provided that the electrical contacting device on the base support a connection means, in particular a luster terminal, and with this electrically connected electrical contact elements and on the luminaire part to matching electrical mating contact elements and electrically connected to these luminaire connection means, in particular a luster terminal comprises. The base support has connection means, in particular a luster terminal, with which it can be connected to the electrical connection in the ceiling or wall.

Thus, first of all, the base support with its connection means can be connected to a ceiling-side or wall-side electrical connection and mounted on the ceiling or wall. Subsequently, a luminaire can be electrically connected to the luminaire part via the luminaire connection means. This can be done away from an attachment point of the lamp on the wall or ceiling. Finally, the light part prepared in this way can be electrically connected to the base support and simply fixed by the fastening coupling to the already installed base support in order to mount the light.

In order to further simplify the production of the electrical connection between the luminaire part and the electrical connection, for example in the form of electrical cables located in a ceiling or wall, the electrical contacting device can be arranged and / or designed such that an electrical contact device Connection between an electrical connection and the light part can be produced by closing the mounting coupling.

In this way it is possible to make an electrical contact without a separate wiring work between the light part and the base support on the ceiling or wall. Rather, it is sufficient to set the light part in the manner described above using the mounting coupling to the base support. As a result of the corresponding arrangement or design of the contacting device, the electrical connection is thereby automatically generated or closed.

It can be particularly advantageous if the electrical contact elements on the base support and the electrical mating contact elements on the luminaire part are arranged and / or formed such that an electrical connection between an electrical connection and the luminaire part can be produced by closing the attachment coupling.

At this point it should be noted that in this case only a comparatively simple wiring of the base carrier to connecting cables protruding from the ceiling or wall is necessary. As stated above, it can be advantageous if the contacting device has on the side of the base support, for example, a corresponding connection means, for example in the form of a luster terminal. In this way, the base support can be electrically connected to existing connection lines before mounting on the ceiling or wall. The necessary in particular with a change of lights overhead cabling the on the luminaire provided connecting cables or cables hanging on a wall Lustererklemme deleted by the above-described contacting device of the fastening device according to the invention.

In particular, in such a luminaire part, which may be provided separately from a luminaire, the cabling possibly required here between the luminaire and the countercontact elements present on the luminaire part can take place in a more comfortable position away from the actual attachment point of the luminaire. Overhead work is not necessary.

In such luminaire parts, which are for example not non-destructively detachable on a lamp, so formed as part of the lamp, the light-side cabling work on the luminaire part for the end user can be completely eliminated.

In a particularly preferred embodiment of the fastening device, the electrical contacting device may have at least two or three or four or more, preferably spring-loaded contact pins as contact elements on the base support. On the luminaire part, the fastening device can then have in number and arrangement corresponding slip rings or slip ring plates and / or at least one centric contact socket and / or a central counter-pin as mating contact elements. In this way, an electrical contacting device is provided which allows electrical contact between the base support and the luminaire part of the fastening device even with different rotational positions of the luminaire part to the base support. This is done in particular via the preferably concentric slip rings or slip ring plates, which can reliably contact the preferably spring-mounted contact pins at any rotational position of the light portion relative to the base support. The base support or the luminaire part may have receiving openings for the contact pins, in which the contact pins are positioned or arranged in the position of use.

It may be advantageous if the contact pins, in particular at one end, have a cross-sectional widening, for example an edge or a brim, whose diameters are greater than a diameter of receiving openings for the contact pins in the base support or luminaire part. In this way it is prevented that the contact pin provided with such a cross-sectional widening falls out through the receiving opening and is lost, for example, if a spring plate or a spring tongue should break, via which it can be connected to the base support or with the light part.

In principle, a reverse arrangement of the contact pin or the contact socket, the central counter-spins and / or the slip rings or slip ring plates is possible. Thus, in another embodiment of the electrical contacting device may be provided that at least two or three or four or more, preferably spring-mounted, contact pins as mating contact elements on the luminaire part and in number and arrangement corresponding slip rings or slip ring plates and / or at least one centrally disposed contact socket and / or a centrally arranged counter-pin are provided as contact elements on the base support.

In a particularly preferred embodiment of the fastening device for safety reasons, it may be provided that the base support or the luminaire part have annular grooves for receiving slip rings or slip ring plates and / or a centric bolt receptacle for a contact bolt. Within the annular grooves and / or the bolt receptacle are then each free contact ends of the contact elements, in particular contact pins, which are then arranged at a distance from a slot opening of the annular grooves and / or an opening of the bolt receptacle. This variant of the fastening device is particularly useful when a direct contact of a user with the live contact pins should be avoided. Thus, it is particularly advantageous to provide the annular grooves and / or the bolt receptacle and the contact elements or contact pins on the base support, which is connected to the current-carrying cables of the ceiling and / or wall.

Advantageously, the attachment coupling may be formed as a bayonet coupling. Such a bayonet coupling can be closed by a plug-in rotational movement of the counter-coupling element relative to the coupling element. In particular, when using a contacting device, as described above, such a bayonet coupling is advantageous as a mounting coupling, since so the mechanical fastening movement for closing the mounting coupling can also be made simultaneously for connecting the lamp to the ceiling or wall side existing connection lines.

In order to prevent inadvertent release of the mounting coupling and thus inadvertent release of the lamp from the wall or ceiling, it may be advantageous if the fastening device has at least one effective between the coupling element and the counter-coupling element fuse element.

The coupling element according to the invention is a rotary ring with at least two, but preferably three, in particular evenly distributed around a center of the rotary ring arranged holding projections. According to the invention, the counter-coupling element, corresponding to the coupling element, then has at least two or more holding receptacles matching the holding projections. The coupling element can be used to close the mounting coupling with its holding projections in the appropriate holding receptacles on the counter-coupling element. It should be noted that, of course, a reverse arrangement of retaining projections and retaining seats may be possible according to the invention. Thus, it is also conceivable that the counter-coupling element is formed as a ring with at least two retaining projections, which are preferably evenly distributed around a center or a longitudinal center axis of the counter-coupling element. Accordingly, the coupling element may comprise at least two, or in number and arrangement corresponding retaining seats which are formed to match the retaining projections of the counter-coupling element.

Within the holding receptacles, whether they are formed on the coupling element or on the counter-coupling element, one, in particular radially oriented, safety projection can be provided as securing elements.

A clear height of each securing projection may correspond to at least a quarter of a clear height of the retaining projections, in particular of the coupling element. In this way, inadvertent release of the mounting coupling is effectively avoided. To solve the mounting coupling, an axial relative movement between the coupling element and the counter-coupling element to overcome the clear height of the holding projections must be made. Only when the clear height of the retaining projections has been overcome by a corresponding axial movement, the mounting coupling, in particular if it is designed as a bayonet coupling, can be solved by a corresponding movement or rotational movement.

In order to ensure the release of the mounting coupling even with existing securing elements, in particular securing projections, it may be advantageous if a distance of the securing elements to a base of their retaining receptacles is greater than a clear height of the retaining projections themselves. In this way it can be ensured that the holding projections comfortably through the resulting gap between the respective securing element and the base of the holding receptacle in which the securing element is formed or arranged to fit to remove the respective retaining projection from the holding receptacle and the mounting coupling to to solve.

In this case, this distance may be, for example, one and a quarter, one-third, one and a half times or twice or more times the clear height of the retaining projections.

A clear height of the securing projections may also be smaller than a distance measured between the counter-coupling element in the position of use and a wall or ceiling-side upper side of the coupling element. In this way it can be ensured that the axial displacement of the counter-coupling element is sufficient relative to the coupling element to the stop on the ceiling or wall to bring the securing element, in particular the securing projections, out of engagement with the retaining projections of the coupling element.

Furthermore, it is possible for the coupling element to be spaced apart when the fastening coupling is closed relative to a wall or ceiling-side base side of the base support. This is useful to allow relative rotation of the coupling element relative to the base support. In particular, when the coupling element is provided on its wall or ceiling side top with a slip-resistant coating or made of an anti-slip material, this distance is useful to allow a rotatability of the connected via the attachment coupling with the base support light portion relative to the base support and not to hinder.

In a variant of the fastening device can be provided that the luminaire part, in particular on its front side facing away from the base carrier, has a fastening means for a lamp. The attachment means may be, for example, a suspension hook or an eyelet, in which a lamp can be hung with a corresponding counter-fastening means.

Another embodiment of the fastening device provides that the luminaire part is an integral part of a luminaire.

In this way, thus form the lighting part of the fastening device and the lamp a unit. Thus, in a standardized design of the base and luminaire part a particularly simple replacement of such equipped lights may be possible. In addition, a series of lights is conceivable that match at least in terms of the design of their lighting parts and are so easily interchangeable and all fit to an already mounted base.

In addition, it is possible for a light source, preferably via a light bulb socket of a luminaire, to be detachably connected, at least indirectly, to the luminaire part. As light bulbs in this case a wide variety of lamps, such as halogen lamps or LED lamps can be used. If the light bulb is worn, it can be removed from the light part and replaced with a new one.

The object mentioned at the outset is also achieved by a use of a fastening device according to the invention according to claim 16. Here, the base of the fastening device is first mounted together with the coupling element on a ceiling or wall. Subsequently, a luminaire part connected to a luminaire is fastened to the base by closing the coupling device. Thus, the installation of the light on the wall or ceiling is completed in a particularly simple and straightforward way.

It may be particularly advantageous when it is provided that an electrical connection between the base support and the luminaire part and a lamp connected thereto via the electrical contacting device of the fastening device is made when closing the mounting coupling. In this way, therefore, a separate wiring and often associated overhead work for electrical connection of the lamp during assembly are avoided.

Only in a first mounting of the base support on a ceiling or wall, it is once necessary to connect the base support and its contact elements with corresponding electrical lines that are present on the wall or ceiling.

It should be noted that the base support of the fastening device can be provided in a so-called surface-mounted variant. But it is also possible to engage the base support in a ceiling or wall, so provide as a flush-mounted version.

The 1 to 7 show a designated as a whole by 1 fastening device for lights on a ceiling or wall with a ceiling or wall mountable, stationary in its position of use base support 2 and a luminaire part which can be fastened or fastened to a luminaire 3 ,

The stationary base support provided on a ceiling or wall 2 is before a montage of a Luminaire attached to a wall or ceiling on the wall or ceiling. For this purpose, the basic carrier 2 several through-openings 4 on, through the screws to attach the base support 2 can be pushed through the wall or ceiling.

For releasable attachment of the luminaire part 3 on the basic carrier 2 and thus also for releasable attachment of a lamp to a wall or ceiling, the fastening device 1 also a mounting coupling 5 on. The mounting coupling 5 includes one on the base support 2 arranged in the use position and relative to this rotatable coupling element 6 and a non-rotatable with the light part 3 connected, to the coupling element 6 complementary counter-coupling element 7 ,

A significant feature of the in the 1 to 7 illustrated fastening device 1 is now that the coupling element 6 in with the counter-coupling element 7 coupled use position together with the light part 3 relative to the basic carrier 2 the fastening device 1 is rotatable.

In this way, one can be by means of the fastening device 1 mounted on a wall or ceiling lamp even when the coupling is closed 5 due to the rotatability of the coupling element 6 , the counter-coupling element 7 and the lighting part 3 relative to the basic carrier 2 align later. This is especially noticeable in the case of elongated luminaires, in particular suspended luminaires, in which deviations from a desired target orientation immediately attract attention and are perceived as disturbing.

The mounting coupling 5 can be closed without tools and also loosened again. This greatly simplifies the handling of the fastening device during assembly or when changing a lamp.

The coupling element 6 is relative to the basic carrier 2 axially displaceable. This promotes opening or releasing the mounting coupling 5 , As a result, it is possible, the coupling element 6 by a corresponding movement as far as axially relative to the base support 2 until it hits a wall or ceiling. Due to the frictional contact with the wall or ceiling, a release force for releasing the attachment coupling 5 on the counter-coupling element 7 and the coupling element 6 be transmitted.

To loosen the mounting coupling 5 to facilitate, has the coupling element 6 on its wall or ceiling side top 8th an anti-slip coating or consists of an anti-slip material. In this way, when pressing the coupling element 6 slightly increased friction or retention force generated on the wall or ceiling and the mounting coupling 5 be solved even easier and more reliable.

The fastening device 1 also has an electrical contacting device 9 on. The electrical contacting device 9 serves to make an electrical connection between one with the light part 3 connected light and an electrical connection 10 , which is usually in a wall or ceiling for connecting lights ready to produce.

The electrical contacting device 9 includes electrical contact elements 11 on the basic carrier 2 and electrical mating contact elements 12 on the luminaire part 3 ,

The electrical contacting device 9 and their electrical contact elements 11 as well as their electrical mating contact elements 12 on the luminaire part 3 are arranged and configured such that an electrical connection between the electrical connection 10 and the luminaire part 3 and thus also between the electrical connection 10 and the one with the light part 3 electrically connected light by closing the mounting coupling 5 is automatically produced. So is the connection of the light part 3 with the basic carrier 2 the fastening device 1 a separate wiring, which usually has to be done overhead when a lamp is to be attached to a ceiling, not necessary. With the installation of the lamp on the wall or ceiling is automatically the electrical contact of the lamp to the connection 10 made in the wall or ceiling.

At this point it should be mentioned that during an initial assembly of the basic carrier 2 on a wall or ceiling this for connection of its contact elements 11 to the mains naturally with the electrical connection 10 the wall or ceiling must be connected. However, this work only has to be done once. Each luminaire, with a matching luminaire part 3 equipped, can then be by a comparatively simple closing of the mounting coupling 5 not only with the basic carrier 2 mechanically connect, but also electrically to the electrical connection 10 connect.

The electrical contacting device 9 has as contact elements 11 on the basic carrier 2 four in total via one spring tongue or one spring plate 13 resiliently mounted contact pins 14 on. How the particular 1 . 5 and 6 clarify, each is the contact pin 14 in one the basic carrier 2 penetrating receiving opening 15 positioned.

At the light part 3 are in number and arrangement corresponding concentric slip ring plates 16 as well as a centric counter contact 17 as mating contact elements 12 the contacting device 9 intended.

The basic carrier 2 has a total of three concentric with each other arranged annular grooves 18 and a centric bolt receptacle 18a on. The ring grooves 18 serve to accommodate the slip ring plates 16 of the lighting part 3 , Inside the ring grooves 18 and the centric bolt holder 18a are free contact ends of the contact pins 14 with a distance to a slot opening 19 the ring grooves 18 or to an opening 19a the bolt receptacle 18a arranged.

The contact pins 14 be from a top of the base vehicle 2 through the previously mentioned receiving openings 15 at the back in the annular grooves 18 or in the bolt receptacle 18a inserted. The dimensions of the contact pins 14 are doing so on the depth of the annular grooves 18 or the bolt receptacle 18a matched that the contact pins 14 with their free contact ends not from the annular grooves 18 or from the bolt receptacle 18a protrude.

Due to the spring-loaded contact pins 14 , wherein this suspension of the contact pin 14 using the spring plates 13 over which the contact pins 14 with the basic carrier 2 are connected, can be a particularly reliable electrical contact or electrical connection between the light part 3 and the basic carrier 2 using the contacting device 9 getting produced.

In an embodiment of the fastening device not shown in the figures 1 is provided that the contact pins 14 at a rear end of a cross-sectional widening, for example, have a rim or a brim whose diameter is greater than a diameter of the receiving openings 15 is. In this way it is prevented that provided with such a cross-sectional widening contact pin 14 through the receiving openings 15 fall out and get lost, for example, if the spring plates 13 over which the contact pins 14 with the basic carrier 2 or with the light part 3 are connected.

The mounting coupling 5 the fastening device shown in the figures 1 is designed as a bayonet coupling, which by a plug-in rotary movement of the counter-coupling element 7 relative to the coupling element 6 is closed.

The counter-coupling element 7 and the light part 3 together form a homogeneous, monolithic unit. It can also be said that the luminaire part 3 and the counter-coupling element 7 are integrally connected to each other.

The mounting coupling 5 has several between the coupling element 6 and the counter-coupling element 7 effective security elements 20 on. The security elements 20 serve to unintentional release of the mounting coupling 5 to prevent.

The coupling element 6 is designed as a rotary ring and has at least two, preferably three or more holding projections 21 on. The counter-coupling element 7 is with a corresponding number of to the retaining projections 21 matching holding shots 22 fitted. The retaining projections 21 and holding shots 22 are good in the 1 to 4 to recognize. Each of the holding shots 22 has an upper-side insertion opening 23 on, through which the retaining projections 21 of the coupling element 6 in the holding shots 22 of the counter-coupling element 7 inserted and by a relative rotational movement of the counter-coupling element 7 to the coupling element 6 in the in the 2 and 3 shown position can be indented.

Inside each of the holding shots 22 is each a fuse element 20 arranged or formed. According to 3 these are the security elements 20 each one radially to the center of the luminaire part 3 or the counter-coupling element 7 oriented security advantage 24 , A clear height of the securing projection 24 is at least a quarter ( 1 / 4 ) or more of a clear height of the retaining projections 21 of the coupling element 6 ,

A distance D1 the respective security elements 20 . 24 within the holding shots 22 for a reason 25 the holding shots 22 is greater than a clear height of the retaining projections 21 , The distance can be D1 one-quarter, one-third, one-half times, or twice or more times the clear height of the retaining projections 21 of the coupling element 6 be. That way is the distance D1 sufficiently large, to a comparatively simple, but conscious release of the mounting coupling 5 by the user of the fastening device 1 to allow.

A clear height of the security elements 20 . 24 is smaller than one between the in-use position mating coupling element 7 and a wall or ceiling top side 8th of the coupling element 6 measured distance D2 (see. 2 ). Thus, the available axial displacement of the counter-coupling element 7 relative to the coupling element 6 big enough, around the height of the security elements 20 . 24 for releasing the mounting coupling 5 to overcome.

The coupling element 6 also indicates when the coupling is closed 5 and in the use position of the lamp on the fastening device 1 a distance to a wall or ceiling side base 26 of the basic carrier 2 on. In this way it is ensured that a free rotation of the coupling element 6 relative to the basic carrier 2 not by a concern of the coupling element 6 hindered on a wall or ceiling.

In the embodiment shown in the figures it can be seen that the luminaire part 3 a fastener 27 in the form of a hanging hook for a lamp. At this fastener 27 a light can be hung.

A wiring of the luminaire with a luminaire connection means 28 , here a luster terminal 28 , the lighting part 3 is also from the basic carrier 2 dissolved luminaire part 3 possible. Therefore, the electrical connection of the lamp to the luminaire part 3 be made in a comfortable attitude away from the actual attachment point of the lamp. This increases the comfort when using the fastening device 1 and during the assembly of the lamp considerably. The luster terminal 28 is via a corresponding power supply with the electrical mating contact elements 12 on the luminaire part 3 electrically connected.

In another, not shown in the figures embodiment of the fastening device 1 is the light part 3 integral part of a luminaire. This means that the luminaire part can not be removed from the luminaire without a certain amount of effort, for example by using tools. This has the advantage that an end customer a lamp already with firmly mounted and also electrically connected lighting part 3 can be offered. Thus, a series of with standardized lighting parts 3 equipped luminaires conceivable that a particularly simple change of the lights on one with a corresponding base support 2 such a fastening device 1 fitted mounting point allowed.

About a bulb socket of a lamp, a light source can be releasably connected at least indirectly to the light part. As lamps, a wide variety of lamps, such as halogen lamps or LED lamps can be used. If the light bulb is worn, it can be removed from the light part and replaced with a new one.

When using the fastening device 1 is provided that initially the basic part 2 with the coupling element 6 is mounted on a ceiling or wall. This is usually already a wiring of the electrical contact elements 11 with an existing electrical connection 10 the wall or ceiling made. For this purpose, the basic carrier 2 as connection means 29 a luster terminal 29 on that with the electrical contact elements 11 of the basic carrier 2 electrically connected. This is for example in 1 shown in a very schematic way.

Subsequently, a lamp part connected to a luminaire 3 by closing the coupling device 5 at the base 2 and thus also attached to the wall or ceiling.

The electrical connection between the base support 2 and the luminaire part 3 and thus between the connection 10 and the electric with the light part 3 and its mating contact elements 12 connected light is on the electrical contacting device 9 the fastening device 1 when closing the mounting coupling 5 preferably made automatically.

The invention is concerned with the fastening device 1 and their use for mounting or mounting a luminaire to a wall or ceiling. To simplify the mounting or mounting of the lamp, has the fastening device 1 the stationary base to be fixed to a wall or ceiling 2 and the luminaire part connectable or connected to a luminaire 3 on. The fastening device 1 further includes the attachment coupling 5 that is a coupling element 6 on the basic carrier 2 and a mating coupling element designed to correspond thereto 7 on the luminaire part 3 includes.
