• Einbringen der Lichtbereitstellungseinrichtung in den Innenraum und Koppeln der Lichtbereitstellungseinrichtung mit dem Kanal, um die Lichtbereitstellungseinrichtung innerhalb des Innenraums zu halten; und
• Positionieren der Lichtbereitstellungseinrichtung in der Weise, dass die Lichtbereitstellungseinrichtung, bei Bedarf nach zusätzlichem Ausrichten derselben, im Betrieb Licht durch den Lichtaustrittsbereich nach außen abgeben kann.

Furthermore, a method for constructing a lighting arrangement according to the invention is proposed, the method comprising the steps:

• Providing a channel having an interior space and a light exit area, and providing at least one light providing device;
• Inserting the light providing means into the interior and coupling the light providing means to the channel to hold the light providing means inside the interior space; and
• Positioning the light providing device in such a way that the light providing device, if necessary for additional alignment of the same, during operation can emit light through the light exit area to the outside.

One idea of the present invention is to provide the arrangement of the light providing device within the interior of the channel and illuminating or outwardly by directing light out through the light exit area with free positioning of the light providing device within the interior, or at least within a region of the interior, to combine and at the same time the great freedom that the interior of the channel with respect to a flexible positioning of the light providing device not only in a transverse direction of the channel, but also along a longitudinal extent of the channel, by providing a power rail for supplying the light providing device in a simple and effective way use. The length and shape of the channel can also be advantageously adapted very flexibly to the lighting requirements and / or the size of the room.

The free positioning of the light providing device makes it possible to illuminate the light providing device exactly in the desired, desired for aesthetic reasons, way through the light exit area. This can also be advantageous if, within a space, the arrangement of the objects to be illuminated changes, for example, after some time. By providing a bus bar, the light provider can be flexibly and freely positioned even over long channel lengths. It is created by the invention, a highly flexible lighting option, which in addition, by the arrangement of the light providing device in the interior and the illumination by the light exit area, advantageous Entblendungseigenschaften.

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

According to one embodiment of the invention, the busbar from outside the interior is not visible. In this way, for example, a particularly simple and discreet appearance of the lighting arrangement can be achieved.

According to the invention, the busbar is arranged laterally of the light exit region. This makes it easier to avoid visibility of the busbar from the outside.

In one embodiment, it is provided that the light supply device can be coupled to a component of the channel by means of magnetic force for fastening the light supply device to the channel at different locations within the interior. The attachment of the light providing device is thus achieved in a simple and reliable manner.

In particular, in one embodiment, the light supply device for the coupling with the channel may be magnetically adhered to at least one inner surface region of the channel. In this way, a particularly simple, effective and flexible attachment of the light-providing device within the interior succeeds, such that the light-providing device can be freely positioned.

According to the invention, the light-providing device has at least one magnet, in particular a permanent magnet, by means of which the coupling of the light-providing device to the channel is made possible.

In one embodiment, the light exit region is formed narrowed relative to the interior of the channel. This facilitates the glare and "hide" the light providing device (s) in the channel.

In one embodiment, the light exit region is designed as a slot-shaped opening, wherein the light-providing device arranged within the interior can deliver light directed outside only through the light exit region. This contributes to advantageous anti-glare properties of the lighting device and to a discreet and simple lighting solution.

In one embodiment, the channel is formed with at least one single or multi-part housing component with ceiling and wall sections and with an open side. Here, the light exit region is formed transversely to a longitudinal direction of the channel smaller than the open side of the housing component. The light-providing device or a plurality of light-providing devices can or can be "hidden" in this way in a particularly discreet manner in the interior, while nevertheless maintaining a targeted, directed release of light through the light exit region.

In a further development, the light supply device can be coupled to the housing component by means of magnetic force. Preferably, in this case, the housing component is formed with a material that allows such a coupling.

The housing component may be formed in a configuration with a quadrangular, in particular rectangular, cross-section, or with a quadrangular, in particular rectangular cross-section with one or more rounded corners. Such a housing component allows the accommodation of the light providing devices in the interior in a simple manner.

In one embodiment, the wall and / or ceiling sections of the housing component, and in particular the inner surface areas of the housing component in the region of the wall and / or ceiling sections thereof, are substantially planar. Such a configuration facilitates the holding of the at least one light providing device by means of magnetic force.

In particular, in one embodiment, the housing component may be formed as a sheet metal part, for example made of sheet steel, or with one or more sheet metal parts, for example made of sheet steel.

In one embodiment, the channel further comprises in the region of the open side of the housing component with the housing component coupled profile-shaped components, wherein the profile-shaped components define the light exit region. By using separately provided profile-shaped components, it is optionally possible to provide desired, more complex geometries in a relatively simple manner in the region of the boundary of the light exit region.

In a further development, the profile-shaped components of the channel are adapted to be arranged in sections on a side facing away from a visible side of a plate member an edge of the plate member across the plate member. In this way, the channel can be hidden from the outside largely invisible behind a suspended ceiling, with only the light exit area can be seen from the outside, ie the side of the ceiling facing a room. A discreet and aesthetic lighting solution is thereby possible. However, the flexibility for the user with regard to the objects or room areas to be illuminated remains intact, even if the channel is permanently installed behind the ceiling and, for example, spatulated on the visible side, for example laterally of the light exit area.

The plate element is in particular made opaque and can be designed, for example, as a plasterboard, for example for a false ceiling or a wall cladding.

In one embodiment, the profile-shaped components are formed as metal profiles, wherein the profile-shaped components are made in particular of aluminum or an aluminum alloy material. The metal profiles can be extruded, for example, which also profiled components of complicated cross-sectional geometry can be produced economically.

In one embodiment, the busbar is arranged in or on one of the profile-shaped components or formed in or on the profile-shaped component such that the busbar is accessible from the interior. In this way, accessibility for the supply of the light providing device is ensured, while at the same time the busbar well in the interior, hidden from the visible side of the ceiling can not be hidden.

In particular, at least one of the profile-shaped components or both profile-shaped components can each be formed with a receiving area for receiving the busbar.

According to a preferred embodiment of the invention, the busbar is designed as a two-phase busbar. In this embodiment, the busbar is thus relatively simple.

The busbar is set up in a preferred embodiment for supplying the light providing device (s) with electric current at a voltage of 48 volts.

In particular, the busbar can run substantially parallel to the light exit region. In this way, a power supply for the light providing device (s) can always be reliably made possible along the light exit region.

According to the invention, the lighting arrangement on a provided for the supply of the light providing device line, in particular a cable, as well as an electrically couplable with the busbar connection adapter. The line in this case electrically couples the connection adapter to the light providing device. In this way, a flexible positioning of the light providing device is possible relative to the connection adapter coupled to the busbar. Preferably, the line is here flexible and flexible.

In an advantageous development, provision can be made for at least one bus bar for the supply to be provided on both longitudinal sides of the light exit area the light providing device is arranged in the interior of the channel. Thus, the length of the line to be disposed within the channel can be kept low, and the power supply of the light providing device succeeds in a still simpler and more flexible manner.

In a further development of the connection adapter is equipped with one or more locking device (s) that allows a detent and preferably releasable coupling of the connection adapter with one of the profile-shaped components or allow. Thus, the connection adapter can be easily mechanically held on the profile-shaped component, which is equipped with the busbar.

According to one embodiment of the invention, the line is designed such that it can be magnetically coupled to a component of the channel and thereby held and / or guided within the interior. This design can also be used in combination with the busbar to flexible, free positioning of the light providing device, because by the magnetic coupling of the line with the channel and thereby achieved leadership of the line, this can, depending on the positioning of the light providing device, located exactly there and be held where it least disturbs. In particular, it is avoided that the line hangs in the light cone or light beam provided by the light providing device. In this way, the arrangement of multiple light providing devices within the interior and their positioning is greatly facilitated.

The line for the supply of the light-providing device may in particular be a cable for supplying the light-providing device with electric current. In the case of several light providing devices, each of these preferably has its own such supply line.

In one embodiment, the conduit for the magnetic coupling with the component of the channel may be provided with a jacket containing one or more magnetic components, or the conduit may be provided along the longitudinal extension with one or more magnetic retaining elements.

According to a preferred embodiment, the connection adapter or the light providing device has a device which makes it possible to receive control signals for switching and / or controlling the light output of the light providing device by wireless route. For example, the device may be configured to receive and process such control signals according to the ZigBee specification.

In one development, the lighting arrangement has a plurality of light providing devices, wherein each of the light providing devices is freely positionable at least within a region of the interior space. In particular, the illumination arrangement can have, for example, two, three or four or even substantially more light-providing devices. In this way, by means of the lighting arrangement, for example, several objects at different locations in a room can be illuminated at the same time. For this purpose, the plurality of light supply devices are preferably arranged within the interior in such a way that, during operation, they can emit light through the light exit region to the outside. The lighting of several objects or room areas thus succeeds in a flexible and also discreet way. However, it is also conceivable that in the lighting arrangement exactly one light providing device is arranged within the interior, although channels of greater length, in particular, are suitable for accommodating a multiplicity of light provision devices.

The plurality of light providing devices can in particular be coupled to the channel in the same way. In a further embodiment, the plurality of light providing devices can be designed in each case in the same way in particular.

In a further embodiment, the illumination arrangement has differently configured light-providing devices. In particular, in this case each of the light providing devices is freely positionable at least within a region of the interior. Thus, the variety of lighting effects that can be achieved by means of the lighting arrangement can be further increased. In particular, in one embodiment, it is conceivable to provide differently configured light provision devices which can be coupled in the same way to the channel.

According to one embodiment, the light-providing device has a soft component, which comes into contact with the channel when the light-providing device is coupled to the channel. In particular, the soft component may be formed as a felt element. The soft component contributes to noise reduction in coupling the light providing device to the channel, and may also help to protect the inner surfaces of the channel from surface damage such as scratching. In addition, a positioning and varying the positioning without damage and low noise possible.

In addition to the free positioning capability of the light supply device, in a further development the light supply device can furthermore be aligned and / or adjusted as needed to change a emission direction of the light supply device. In this way, the flexibility can be further improved with respect to the illumination of different objects or the achievement of desired aesthetic lighting effects. For this purpose, the light supply device can have, for example, a pivotable functional section.

In one embodiment, the light delivery device for the directed emission of light includes a light source with a medium or preferably narrow beam angle. For example, the beam angle of the light source may be up to and including about 25 degrees, for example, the beam angle may be between about 6 degrees and about 25 degrees. In a variant, it would be conceivable that the light source has a maximum beam angle of 15 degrees. The use of particularly narrow-beaming light sources allows targeted delivery of light through the light exit area to the outside in order to specifically illuminate a room area or object. An unwanted illumination of the channel interior by the light providing device is avoided.

In one embodiment, the light providing device has a function section which is round in cross-section. In this case, provision is made in particular for a diameter of the functional section to be smaller than a width of the light exit area. Such a functional section is often handy and space-saving.

In an alternative embodiment, the light providing device is formed with a linear elongated shape or has a functional portion formed with a linear elongated shape. In this case, the linearly elongated shape may be formed in particular cuboid. In particular, a longitudinal extent of the linearly elongate shape can also exceed a width of the light exit area. With this embodiment of the invention, for example, the lighting of larger areas or areas or objects by means of a light providing device at the same time good glare can succeed.

For example, in an advantageous development, the linearly elongate shape can extend parallel to the light exit region.

In one embodiment of the invention, the lighting arrangement has at least one additional light providing device, which is designed for arranging the same at least in sections within the interior space and can be electrically coupled to the busbar and can be coupled to the channel for holding the additional light providing device. In this case, the additional light-providing device is formed with a linearly elongate shape or has a functional section formed with a linearly elongate shape. In this way, additional, additional lighting effects can be achieved, for example, the illumination of larger areas or areas of space.

The linearly elongate shape of the additional light-providing device can be cuboid in particular.

In particular, it can be provided in a development that the additional light providing device can be arranged in the interior such that it is flush with the plate elements on the visible side of the plate elements. With this development, it becomes possible to provide further lighting effects in a flexible manner and to complement the light effects made possible by means of the light providing device in the interior advantageous.

The additional light supply device can fill in embodiments of the invention in a state coupled to the channel, the light exit region in a direction transverse to the longitudinal direction of the channel substantially completely or only partially.

In a further embodiment, the additional light-providing device can protrude outwardly from the interior through the light exit region in a state coupled to the channel, such that the additional light-providing device emits light outside the interior. For example, the additional light providing device may be configured as a "wallwasher" for irradiating a wall, or may be equipped with an opal light emitting area located outside the interior in the state of the additional light providing device coupled to the channel. Thus, with this embodiment, further lighting effects can be created in a flexible and versatile manner, and the light effects made possible by the light supply device in the interior can be advantageously supplemented.

In further embodiments, a plurality of additional light providing devices may be provided, wherein these may be formed in the same or different ways.

In an advantageous embodiment, the lighting arrangement further comprises at least one additional light source, which is arranged and designed to emit light into the interior and thereby illuminate the channel. In this way, a particularly interesting aesthetic effect can be achieved by not only the illumination of about objects in space through the light exit area is made possible through it, but the interior itself gives the impression to shine. With a slit-shaped light exit area, the impression of an indirectly illuminating, slit-shaped light exit hole can be achieved ("glowing").

In one embodiment, at least one of the profile-shaped components or both profile-shaped components are each formed with a receiving area for receiving the additional light source. Thus, the additional light source can be conveniently accommodated.

In particular, in a development, the additional light source facing the interior can be arranged in a groove of the profile-shaped component, whereby a body portion of the profile-shaped component is located between the light exit region and the additional light source. Thus, the additional light source can not be seen from the visible side, which further improves the aesthetic effect of the backlighting or "glowing".

The additional light source can be formed in an embodiment with at least one LED or an LED array. As a result, the channel can be illuminated in a space-saving and energy-efficient manner.

Furthermore, in a further development, the additional light source can have a light-permeable cover, in particular an opal cover. The opal cover can be formed, for example, with a plastic material, for example PMMA. This can contribute to even more even illumination of the channel.

In one embodiment, in each case an additional light source is arranged on both longitudinal sides of the light exit region. In this way, for example, an even more homogeneous indirect backlighting of the channel can be made possible.

In one embodiment, the lighting arrangement is formed along the longitudinal direction of the channel with two or more units, wherein adjacent units are respectively coupled by means of a connecting component or by means of a plurality of connecting components. In particular, the units each comprise a channel section with sections of the profile-shaped components and the housing component, as well as at least one busbar section and preferably at least one additional light source or a section thereof.

In one embodiment, the units each extend in a straight line, with adjacent units in each case being coupled to each other in a straight line or in an angled manner by means of the connection component or the connection components.

For example, in embodiments of the invention, the units may be coupled relative to one another at an angle of substantially 90 degrees with each other, wherein in other embodiments, other angles are conceivable.

In a preferred embodiment, two or more units each extend rectilinearly, and further provided as a corner piece further unit is provided, wherein the rectilinear units are respectively coupled by means of the connecting member or the connecting members with the corner piece formed unit. Thus, in this embodiment, the rectilinear units can be coupled together by means of the corner piece in an angled manner.

In this case, the feed line electrically couples the feed component to a power source outside the interior. In this way, electricity can be fed into the busbar in a flexible manner. In particular, the feed line can advantageously be guided through a passage opening in the end termination piece.

In a further development, the feed component is equipped with one or more latching device (s) that enable or enable a latching and preferably releasable coupling of the feed component with one of the profile-shaped components. Also, the feed component can thus be easily mechanically held on the profile-shaped component, which is equipped with the busbar.

In one embodiment, the channel is provided with at least one holding device, preferably with a plurality of holding devices, which is / are set up for fastening the channel to a load-bearing component of a structure, in particular on a raw ceiling or solid ceiling. In particular, further additional fastening elements can be used, if required, for example screws, rods, bands, hooks, chains and / or ropes in order to fasten the channel to the load-bearing component of the building by means of the retaining device (s). The attachment can be done in particular hanging. This embodiment advantageously makes it possible to keep the weight of the channel and the weight of the channel coupled components of the lighting arrangement wholly or at least partially on the load-bearing component of the structure, in particular a load-bearing ceiling. In this way, for example, plate elements of a false ceiling can be relieved.

In a further development, the holding device (s) is / are in each case designed as an angle piece fastened to the channel.

In the method according to the invention, the light supply device is coupled by means of magnetic force with a component of the channel. The advantages of coupling by means of magnetic force have already been mentioned above.

In one embodiment, the method further comprises an adjustment of the light providing device by sliding displacement and / or rotation of the light providing device on the channel. As a result, the adjustment can take place in a particularly simple and flexible manner.

In a further development of the method, the introduction of the light providing device into the interior, the coupling of the same with the channel, and the positioning of the light providing device through a slot-shaped opening which forms or includes the light exit area, take place, in particular after the channel in the region of a ceiling and / or wall is mounted. This is advantageous since, when installing the channel, it is not yet necessary to determine how many light providing devices are to be accommodated in the interior and how these should be aligned. A highly flexible structure of the lighting arrangement is possible in this way.

DESCRIPTION OF EMBODIMENTS

Fig. 1 shows a lighting device 1 according to a first embodiment of the invention. The lighting arrangement 1 has an in Fig. 1 Channel 3 shown in cross-section, which is formed with a housing component 4 constructed from several parts and two profile-shaped components 6. The housing component 4 has mutually parallel wall sections 4a and 4b and a ceiling section 4e. As a result, the housing component 4 on three sides, in detail to the opposite, in Fig. 1 vertically aligned longitudinal sides through the wall sections 4a, 4b and at the in Fig. 1 horizontally aligned top by the ceiling portion 4e substantially closed. In the area of the underside opposite the top, in Fig. 1 the bottom side of the housing component 4, the housing component 4 is open, so has an open side 4f. The underside of the housing component 4 is closed by the profile-shaped components 6 arranged in the region of the open side 4f and coupled to the housing component 4. The profile-shaped components 6 and the housing part 4 can be fastened to one another in a suitable manner in connection regions 6a.

The housing component 4 is formed with a plurality of sheet metal parts to form the wall and ceiling sections 4a, 4b, 4e, for example made of sheet steel. By contrast, the profile-shaped components 6 are made as elongated profiles of a metal material, in particular aluminum or an aluminum alloy material, for. B. by extrusion.

The channel 3 is intended to be arranged and secured behind a suitably dimensioned slot 10a with a width W in a suspended false ceiling 10, in particular a plaster ceiling, between the raw ceiling R and the suspended ceiling 10. The slot 10a can be cut into a plate member 9 of the ceiling 10 and, see Fig. 1 , be bounded by edges 9a of the plate member 9. Alternatively, the slot 10a could be formed by plate elements 9 spaced from one another by the width W of the slot 10a and bounded by a respective edge 9a of one of the plate elements 9. The thickness t of the plate elements 9 may be for example 12.5 mm, with modifications of the embodiment may be adapted to other plate thicknesses t.

In order to fix the channel 3 to the ceiling 10, the lighting arrangement 1 can be particularly suitable, in Fig. 1 Holding means not shown, for example, allow an attachment of the channel 3 at intervals along the longitudinal direction 3a. Fig. 1 also shows a visible side S of the false ceiling 10 and a side facing away from the visible side S 'of the false ceiling 10 and thus the plate elements. 9

The profile-shaped components 6 are arranged for, see Fig. 1 , In each case in sections on the side S 'on the plate elements 9 and arranged to be placed on the plate elements 9 from the side S' forth, wherein in the finished state, see Fig. 1 , Each of the profile-shaped components 6, the edge 9a of the plate member 9, on which the profile-shaped component 6 rests, overlaps. After installation of the channel 3 behind the ceiling 10 can be done about in the context of drywall work, a leveling on the visible side S.

FIG. 1 shows further that the two to a central axis M of the channel 3 symmetrically arranged and formed profile-shaped components 6 to each other their facing edges do not touch, but that between the profile-shaped components 6, a slot-shaped opening 28 is provided, which forms a passage from the visible side S forth to an inner space 5 of the channel 3. The opening 28 serves as a light exit region 31 of the channel 3. With the exception of the opening 28, the open side 4f of the housing component 4 is closed. In a direction transverse to the longitudinal direction 3a (see eg. Fig. 2 ) of the channel 3, the light exit area 31 is smaller than the open side 4f of the housing component 4. In other words, in comparison with the inner space 5 of the channel 3, the light exit area 31 is narrowed. In Fig. 1 is the width of the light exit region 31, taken perpendicular to the longitudinal direction 3a of the channel 3, denoted by the reference B. The profile-shaped components 6 thus limit the light exit region 31.

The lighting arrangement 1 according to the first embodiment further comprises two similar light providing means 36, which in Fig. 1 are shown. The light providing devices 36 are each suitably dimensioned and designed to be arranged inside the interior 5 of the channel 3. In the presentation of the Fig. 1 both light providing devices 36 are arranged in the interior 5. The two light providing devices 36 are in this case in each case completely within the interior 5. In the first embodiment, the light providing means 36 are designed as narrow-beam radiators or "spots". The light providing devices 36 will be described below with reference to FIG Fig. 7-15 will be explained in more detail.

The light supply devices 36 are each intended to emit light L directed toward the outside through the light exit region 31 during operation, that is to say to illuminate it selectively from the interior 5 through the light exit region 31. In the first embodiment, since the plate members 9, the profiled components 6, and the housing component 4 are opaque, the light providing means 36 can radiate light directed outside only through the light exit region 31. In this way, it is possible to selectively illuminate an object located outside of the interior space 5 inside the room, which has the suspended ceiling 10, or a room area, through the light exit area 31, and at the same time achieve a particularly favorable glare-free behavior. The light providing devices 36 are of barely perceptible to a viewer who is in the illuminated space, but still allow a targeted illumination of selected areas of space, architectural features or objects located in the space. This is achieved in that the light providing means 36, seen from outside the interior 5, behind the profile-shaped components 6 and the edge portions of the plate elements 9, on which rest the profile-shaped components 6, arranged in the interior 5 and thus "hidden", ie Light providing means 36 are located opposite a plane 11, which forms an outer side of the ceiling 10, set back behind the ceiling 10.

A light providing device 36, as in the first embodiment of the Fig. 1 is used in is Fig. 7-15 shown in more detail. The light supply device 36 has a function section 45, round in cross-section, with a substantially cylindrical basic shape and a base section 46, wherein the base section 46 is connected to the functional section 45 via a pender 47. Via a pivot axis 48, the functional portion 45 can be pivoted relative to the base portion 46, for example by 90 degrees. A diameter D of the functional portion 45 is smaller than the width B of the light exit portion 31, see Fig. 1 and 10 ,

The light providing device 36 is formed as a radiator or "spot" and has a light source with a narrow beam angle α (see Fig. 1 ) on. In the first embodiment, the beam angle α is at most 25 degrees. The beam angle α may be, for example, between 6 degrees and 25 degrees. By the light providing device 36 having a narrow-beam light source, despite the backward offset of the light providing device 36 behind the plane 11 in the interior 5 into an object outside the interior 5 through the light exit region 31 through targeted, without causing excessive losses due to the illumination of the Interior 5 comes.

Each of the light providing devices 36 can be coupled to the channel 3 by means of the base section 46 in order to hold the light providing device 36 on the channel 3. For this purpose, the base portion 46 on a permanent magnet 55, the is formed in the embodiment shown as a ring magnet. As described above, the housing component 4 is formed with sheet metal parts, wherein in the first embodiment of the housing component 4, a sheet is selected, on which a permanent magnet can exert an attractive force. For example, the housing component 4 is formed with steel sheet. In the rectangular in cross section design of the housing component 4 with flat wall and ceiling sections 4a, 4b, 4e wall portions 5a and 5b and an inner ceiling portion 5e of the inner surface of the housing component 4 are flat.

By means of the permanent magnet 55 arranged in the base section 46, each of the light supply devices 36 can be coupled by magnetic force to the housing component 4 of the channel 3. For this purpose, the respective light supply device 36 is attached with its base portion 46 to one of the inner surface areas 5a-5e magnetically adhesive. The magnet 55 can thus hold the light supply device 36 magnetically adhering both to one of the walls of the housing component 4 in the wall regions 5a, 5b and to the ceiling of the housing component 4 in the ceiling region 5e. This is facilitated by the planar design of the wall and ceiling portions 5a, 5b, 5e, which allow easy abutment of the base portion 46. Each of the light providing means 36 is thus freely positionable within the inner space 5 in such a way that the respective base portion 46 can be magnetically adhered to any free location of the inner surface areas 5a, 5b, 5e as required (see Fig. 1 ). A free positioning of the light providing means 36 is thus achieved in the longitudinal direction 3a of the channel 3, but also a free positioning in the interior 5 is achieved transversely to the longitudinal direction 3a. This is achieved by means of the magnetic coupling to the inner surface areas 5a, 5b, 5e, of which the inner surface area 5e in the sketched embodiment extends substantially parallel to the plate elements 9 and the inner surface areas 5a, 5b extend substantially perpendicular to the plate elements 9. It is understood that collisions of two light providing devices 36 can be avoided by suitably arranging them in the inner space 5.

The light providing devices 36 can thus be positioned freely on the channel 3 within the interior 5, or at least a portion thereof. In Fig. 1 For example, one of the light providing devices 36 is coupled to the housing component 4 in the ceiling area 5e, while the other is coupled to the channel 3 in the wall area 5b.

The light providing means 36 can be slidably displaced and rotated on the housing component 4 due to the attachment by means of the magnetic coupling with the housing component 4, without the position of a light providing means 36 within the interior space 5 being limited to one or more discrete positions. Rather, the positions of the light providing means 36 are continuously variable. Thus, a variety of different arrangements of multiple light providing devices 36 become possible.

An edge of each of the profile-shaped components 6 forms a boundary 33 for the light exit region 31 along a respective longitudinal side 32 thereof. Adjacent to the boundary 33 of the light exit region 31, each of the profile-shaped components 6 is beveled, whereby in the finished lighting arrangement 1, see Fig. 1 , a starting from the opening 28, and thus starting from the visible side S, inwardly, ie towards the inner space 5, expanding region 29 is formed. In the first embodiment, the boundaries 33 are parallel to each other, whereby the area 29 extends over the length of the channel 3 at each point in the same way inwardly. In this way it is avoided that the emission of light by the light providing means 36 is hindered by the profile-shaped components 6, when the light providing means 36 opposite the opening 28 laterally offset behind portions of the profile-shaped components 6, approximately in the vicinity of one of the wall sections 4a or 4b to be positioned.

In Fig. 1 Both the functional portion 45 and the base portion 46 and the Pende 47 are completely within the interior 5. The light providing means 36 of Fig. 1 are each freely positionable as a whole within the interior space 5, are magnetically attachable to a selected location within the interior space 5, and the light providing device 36 is also within the By pivoting the functional section 45, a light providing device 36 coupled to the ceiling section 4e can, for example, illuminate out of the light exit region 31 inclined to a vertical direction V. By way of example, a pivoting of the functional section 45 in FIG Fig. 1 for the light supply device 36 magnetically coupled to the wall section 4b. Further alignment may be accomplished by rotating about a surface normal axis 49 by sliding the base portion 46 on the ceiling portion 5e of the inner surface or about a surface normal axis 49 'by sliding on the wall portion 5b. By means of such adjustment of the functional section 45, in addition to the free positioning of the light providing device 36, the emission direction A of the light providing device 36 can thus be flexibly changed as required.

The light providing means 36 of the Fig. 1 are thus freely and freely positionable within the interior 5 of the channel 3, about the axis 49 or 49 'rotatable and pivotable about the axis 48, so that light L directed through the opening 28 can be radiated to the outside.

The base portion 46 is, see FIGS. 7 to 15 , of substantially cylindrical outer basic shape, wherein the base portion 46 on a side facing away from the functional portion 45, flat end face has a soft component 64, which in the embodiment of the Fig. 7-15 is preferably formed as a circular felt disk. When the light providing device 36 is coupled to the channel 3 by means of the permanent magnet 55, the soft component 64 comes into contact with the ceiling portion 5e or one of the wall portions 5a, 5b of the inner surface of the housing component 4. Noises upon insertion of the light providing means 36 into the inner space 5 and coupling the same to the channel 3, as well as noise and damage to the inner surface portions 5a, 5b, 5e of the housing component 4 during displacement or rotation of the base portion 46 in the magnetically coupled to the housing component 4 state can be avoided by the soft component 64.

The view of Fig. 14 shows individual parts of a light providing device 36 of Fig. 7-13 and 15 , The base portion 46 is formed with a round base housing member 67 which receives the permanent magnet 55 designed as a ring magnet. The ring magnet 55 is in the base housing member 67 in FIG Fig. 14 clamped from above by means of a partially disk-like, provided with openings or holes 66a portion 66, wherein the part 66, the magnet 55, the base housing member 67 and the Pende 47 are held together by means of screws 68. The part 66 may also snap on the base housing part 67. The soft, damage-free and low-noise sliding enabling soft felt element 64 is glued on its underside 65 with the disc-like portion of the perforated portion 66. The part 66 may be made of plastic, for example, the base housing part 67, the Pende 47 and the shell parts 70, for example, metal, such as aluminum. The openings or holes 66 a improve the achieved magnetic holding effect of the magnet 55.

The functional portion 45 is formed with a heat sink 72, an LED module 73 for generating light, an optic 74 such as a lens and / or a reflector, a film 75 for the purpose of optical enhancement, and further a Entblendring 76. For connection of the functional portion 45 by means of the pender 47 with the base portion 46, the shell parts 70 are frictionally held in a recess of the heat sink 72, wherein the shell parts 70 are connected to the Pende 47 by means of a screw 69 and discs 71. By means of the screw 69, the pivot axis 48 is also realized. With the help of the optics 74, the already mentioned narrow beam angle α of the light providing device 36 is made possible.

The number of light providing devices 36 which are arranged within the interior space 5 may vary, for example, depending on the illumination requirement and / or depending on the installed length of the channel 3. Different numbers of light providing devices 36 can be arranged inside the interior 5. In the case of a channel 3 extending transversely through a space in the ceiling region, and thus in the case of an elongated slit-like light exit region 31, a multiplicity of light provision devices 36 can be accommodated in the interior 5 in such a way that they can deliver light L directed toward the outside.

In Fig. 1 are also electrical lines 85, in particular cables, each of the power supply one of the light providing means 36, outlined. Each of the lines 85 is located within the interior space 5.

The lighting arrangement 1 of Fig. 1 also has in the interior 5 of the channel 3 a trained for the supply of the light providing means 36 busbar 95, with each of the light providing means 36 can be electrically coupled separately and at a respectively according to the positioning of the light providing means 36 individually selected position.

The busbar 95 is arranged on one of the profile-shaped components 6 such that the busbar 95 is accessible from the interior 5 to be able to supply the light providing device 36 with power. Out Fig. 1 It can also be seen that the busbar 95 is arranged laterally of the slot-like opening 28, and thus laterally of the light exit area 31. In this way, it is achieved by means of the arrangement of the busbar 95 and the shaping of the profile-shaped component 6 that the busbar 95 from the visible side S can not be seen by a viewer. This is particularly advantageous from an aesthetic point of view and enables a simple, discreet appearance of the lighting arrangement 1.

The busbar 95 is preferably formed in two-phase, adapted to supply the light providing means 36 with electric current at a DC voltage of 48 volts, and is accommodated in a suitable, formed on the profile-shaped component 6 groove-like receiving portion 96. Here, the busbar 95 extends parallel to the light exit region 31 and to its boundaries 33. The busbar 95 may be connected, for example via a transformer, not shown in the figures with a power grid.

Each of the two light-providing devices 36 of the Fig. 1 is electrically connected via an associated one of the electrical lines 85 with one of the light supply device 36 respectively associated terminal adapter 99. In Fig. 1 this is outlined only for one of the light providing devices 36. The connection adapter 99 serves as an electrically coupled to the busbar 95 tapping device to tap electrical current from the busbar 95.

In order to be able to supply each of the light-providing devices 36 with electric current, a line 85 is provided for each of the light-providing devices 36. The supply line 85 is in each case designed such that it can be magnetically coupled to the channel 3, namely to the ferromagnetic housing component 4, whereby the line 85 is guided and held on the inside of the housing component 4 on its way from the connection adapter 99 to the light supply device 36 is prevented sagging of the supply line 85, and thereby also prevents the supply line 85 in an undesirable manner into the light beam or cone generated by the light providing means 36 depending hangs. Fig. 1 shows how, for example, a supply line 85 is magnetically guided along the inner surface regions 5b, 5e. It is understood that supply lines 85 for further light providing devices 36 can be arranged in a similar manner.

The FIGS. 16, 17 and 18 show various variants of how the magnetic coupling of the supply line 85 can be done with the housing component 4, based on exemplary sections of lines 85 ', 85 ", 85"'. The supply line 85 'in FIG. 16 has conductor 86, a jacket 87 and the jacket 87 on the outside surrounding, attached to the jacket 87 ring-like holding elements 88, which in turn are magnetic or in each of which a permanent magnet is embedded. With the supply line 85 "the FIG. 17 Instead of the ring-like holding elements, clips 89 are formed with a ring-like holding section 89a and a magnetic adhesive section 89b. The adhesive portion 89b may be a permanent magnet, or a permanent magnet may be embedded in the adhesive portion 89b. In the variant of FIG. 18 For example, the supply line 85 '''is provided with a cladding 87''', wherein magnetic components, in the form of small individual magnets, magnetized bands or magnetic tissues, may be embedded in the cladding 87 '''. In FIG. 18 only a portion of a magnetized belt 90 is exemplified.

The lighting arrangement 1 of Fig. 1 further comprises an additional light source 78, which is provided in the first embodiment only on one of the longitudinal sides 32 of the light exit region 31 and received in a receiving area 98 in the profile-shaped component 6. During operation, the additional light source 78, which faces the interior 5, emits light into the interior 5, as a result of which the channel 3 itself is illuminated ("glowing"). With the directly provided by the light exit region 31 emitting light providing means 36 thus results in an interesting aesthetic effect, in which emits a very subtle way a spotlight or spot from a self-illuminating slot indirectly.

In the lighting arrangement 1 according to Fig. 1 For example, the inner surface areas 5a-e, and preferably at least the surface of the profile-shaped component 6, are brightly colored in the widening area 29, for example colored white, whereby the effect of "glowing" is particularly pronounced.

In a variant of the first exemplary embodiment in which additional light sources 78 have been omitted and no backlighting of the interior 5 and thus no glowing is desired, the inner surface areas 5a-e and preferably at least also the surface of the profile-shaped component 6 in the widening area 29 dark, for example black, be colored. In such a variant, the impression can be obtained, the light providing device 36 radiate out of a dark hole. Thus, another aesthetic effect can be achieved in which the light providing device 36 seems to float in a dark hole.

The additional light source 78 may be formed in the first embodiment in the same way as below, in particular with reference to Fig. 33-35 is explained in more detail to the second embodiment.

In Fig. 2 is a rectilinear portion of the channel 3 of the lighting device 1 according to FIG Fig. 1 seen from the visible side S of the false ceiling 10. From the visible side S of the channel 3 is substantially the light exit region 31 as an elongated slot, laterally bounded by the profile-shaped components 6, visible. Fig. 2 also shows an example of a light providing device 36, which radiates directly through the light exit region 31 in the middle. Along its longitudinal direction 3a, the channel 3 is constructed with a plurality of channel sections 3b extending in each case in a straight line. The channel sections 3b are each constructed with a portion of the housing component 4 and sections of the profile-shaped components 6 and form with busbar sections 95b and additional light sources 78 rectilinear units 2, along the longitudinal direction 3a of the channel 3 at joints 3c, of which Fig. 3 an example shown, are connected to each other in a straight line. The channel sections 3b, additional light sources 78 or sections thereof and the busbar sections 95b may be of substantially the same length. In this way, the units can be assembled into an overall arrangement of any length. In order to establish the connection of adjacent units 2, are in the embodiment of the Fig. 3 provided for the straight-line connection connecting members 21 and 22 are provided. The connecting members 21 are adapted to allow the electrical coupling of adjacent busbar sections 95b while the connecting members 22 serve to mechanically couple the adjacent channel sections 3b. The number of units 2 can vary depending on the desired overall length of the channel 3, wherein the length of a unit 2 can be suitably chosen in order to handle the units 2 well.

At the front ends of the channel 3 is closed with one end piece 20 each end. This is schematic and exemplary in Fig. 4 shown.

However, the invention not only allows lighting arrangements 1 with rectilinear channel 3. Instead, individual units 2, see FIGS. 5 and 6 , angled relative to each other at a junction 3c are interconnected, for example, at right angles. As a result, on the visible side S, for example, an angle β of 90 degrees angled extending slot, which forms the light exit region 31, achieved. To achieve such a course of the channel 3, are in Fig. 5, 6 adjacent, each rectilinear but obliquely truncated units 2 with rectilinear channel sections 3b at the junction 3c by means of suitable connecting members 21 ', 22' coupled, wherein the connecting members 21 'for the electrical coupling of busbar sections 95b at an angle of β = 90 degrees and the connecting members 22 'for the mechanical coupling of the channel sections 3b are formed at an angle of β = 90 degrees. In Fig. 6 are appropriately trained connection components 21 ', 22' schematically exemplified. The longitudinal direction 3a of the channel 3 as a whole extends in this case thus bent at the point 3c by 90 degrees. Connections of adjacent units 2 in angled by other angle β manner, for example by 30 degrees, 45 degrees, 60 degrees, 120 degrees, 135 degrees or 150 degrees relative to each other, but are conceivable.

Hereinafter, a lighting arrangement 101 according to a second embodiment of the invention with reference to the Figures 19-35 described in more detail. Except for the differences described in detail below, the above comments on the first embodiment also apply to the second embodiment, so that reference is made in this regard to the above explanations to the first embodiment.

The lighting arrangement 101 in turn has a channel 3, which is formed with a housing component 104 and two profile-shaped components 106. The profile-shaped components 106 are made as elongated profiles of a metal material, in particular aluminum or an aluminum alloy material, for. B. extruded. However, in the second embodiment, the housing component 104 is formed as a sheet metal part, in a transverse direction in one piece, which includes wall and ceiling portions 4a, 4b, 4e, wherein the housing component 104 is made of sheet steel by way of example. The cross-section of the housing component 104 is rectangular with planar wall and ceiling sections 4a, 4b, 4e and rounded corners at the transitions of the ceiling section 4e into the wall section 4a and 4b. As in the first embodiment, the housing component 104 is attached to the in Fig. 19 and 20 vertically extending longitudinal sides by wall sections 4a, 4b and on the in Fig. 20 horizontally oriented upper side substantially closed by a ceiling portion 4e and has an open side 4f in the region of the underside opposite the upper side. The underside of the housing component 104 is closed by the profile-shaped components 106, which are fastened to the housing component 104 in connection areas 106a.

The lighting arrangement 101 has in Fig. 19 . 20 . 21, 22 For example, two differently configured light providing devices 36 and 136. Both the light providing means 36 and the light providing means 136 are each suitably dimensioned and configured to be located inside the inner space 5 of the channel 3. In the second exemplary embodiment as well, both light-providing devices 36, 136 are embodied as narrow-radiating radiators or "spots".

The light providing device 36 shown in FIG Fig. 19 . 20 . 21, 22 , has already been referred to above with reference to Fig. 7-15 explained in more detail and is formed as in the first embodiment. The light providing device 136 is in the Fig. 26-29 However, as shown in more detail, the light supplying device 36 basically differs in that the light supplying device 136 has a cross-sectionally round functional portion 145 having a diameter D longer than that of the light supplying device 36. The electric power of the light supplying device 136 may be that of the light supplying device 36 may be different or, if necessary, different therefrom, eg greater than the power of the light providing device 36. The diameter D of the functional portion 145 is smaller than a width B of the light exit area 31, see also Fig. 20 , Thus, in the second exemplary embodiment, provision of light provision devices 36, 136 is provided which differ in their size, in particular in their length in the example shown, and can also have different electrical outputs. The diameters D of the light providing devices 36, 136 may be the same or different.

The light supply devices 36 and 136 are magnetically coupled to the housing component 104 and can be positioned and aligned in the same way as described for the first exemplary embodiment above for the light supply device 36, in order to radiate out in the desired direction through the light exit region 31.

The profile-shaped components 106 each have a groove 8a in the connection region 106a, in which, in the assembled state of the channel 3, an edge of the housing component 104 comes to lie in the region of the open side 4f. Please refer in particular Fig. 19 . 20 and 20A , By means of screws 14 which are guided through suitable holes in the housing component 104 and screwed into a further, the edge of the housing component 104 facing groove 8b of the profile-shaped component 106, the housing component 104 can be screwed to the profile-shaped component 106 and thus in the connection region 106a at this be attached.

Furthermore, each of the profile-shaped components 106 is provided with channel-like grooves 8c and 8d, which respectively point to the inner space 5 and thus away from that side of the profile-shaped component 106, which comes to lie on the plate element 9 in the installed state.

The groove 8c receives a busbar 95 and thus forms a receiving region 96 for this, see in particular Fig. 20A and 23 , The busbar 95 is designed as a two-phase busbar and formed with a main body 97a and two electrical conductors 97b. The groove 8c is provided along its longitudinal direction at the opposite groove walls, near the bottom of the groove 8c, symmetrically to the center of the groove with ribs 15c and 15c '. Behind the opposing lower ribs 15 c, the base body 97 a of the bus bar 95 engages in order to hold it in the groove 8 c.

The groove 8d receives the additional light source 78, see, for example Fig. 19 . 20 . 20A and thus forms a receiving region 98 for the additional light source 78. In order to hold the additional light source 78 in the desired position within the groove 8d, the opposite groove walls of the groove 8d each have a rib 15d, the ribs 15d being symmetrical to the center of the groove Groove 8d are arranged such that in the mounted state, a cover 82 of the additional light source 78, see the explanations below to the Fig. 33-35 , rests on upper edges of the groove walls of the groove 8d, see Fig. 20A ,

The additional light source 78, which may be used in both the first and second embodiments of the present invention, is disclosed in US Pat Fig. 33-35 shown in greater detail. The additional light source 78 is formed as an elongate insert to be inserted into the groove 8d. The additional light source 78 has a board 80 which is mounted on a base profile 83. On the board 80 light-emitting diodes (LEDs) 81 are arranged, of which in Fig. 34, 35th only one is visible. In addition, conductor tracks and optionally required further electronic components for the operation of the LEDs 81 can be arranged on the circuit board 80. The board 80 is connected to a suitable power source in a manner not shown in detail in the figures.

The board 80 and the LEDs 81 are, see FIGS. 34 and 35 Covered by an opal cover 82, the opal cover is exemplified as a profile made of a suitable plastic, for example, satinized PMMA. The opal cover 82 engages over the board 80 and engages on both sides thereof in lateral longitudinal grooves 83 of the base profile.

Fig. 20 shows that in the second embodiment, two additional light sources 78 are provided, each facing the interior 5 in the groove 8 d of a profile-shaped component 106 are arranged. The light sources 78 may rest on the ribs 15d and / or be configured to snap behind them. Additional light sources 78 are thus arranged in the second embodiment on both longitudinal sides 32 of the light exit region 31. Between the light exit region 31 and each of the additional light sources 78 is a section of the profile-shaped component 106, in whose groove 8d the light source 78 is received, whereby the additional light source 78 can not be seen from the visible side S.

The additional light sources 78 emit light into the interior 5 during operation, as a result of which the channel 3 is illuminated. However, as in the first exemplary embodiment, no direct light emission through the light exit region 31 outwards takes place by means of the light sources 78, but the light emitted by the light sources 78 only reaches the viewer indirectly by the backlighting of the channel 3. As a result, the interior 5 itself gives the impression of glowing. The aesthetically pleasing impression of a luminous light exit slit can thereby be achieved, whereby from the luminous slit the light supply devices 36, 136 directed can illuminate an object located in a room.

As in the first embodiment, in the second embodiment, in a variant of the same, the "glowing" and thus the indirect illumination of the interior 5 can be dispensed with, that is to say in the second embodiment. the additional light sources 78 can be omitted in such a variant. With regard to the coloring of the inner surface areas 5a, 5b, 5e and the profile-shaped component 6, in particular in the area 29, reference is made to the above comments on the first embodiment.

For a particularly uniform, homogeneous, indirect backlighting of the channel 3, the provision of additional light sources 78 on both sides of the light exit region 31 and the use of an opal cover 82 contribute. The additional light sources 78 may extend along the entire longitudinal direction 3 a of the channel 3 parallel to the light exit region 31. To facilitate transport and assembly, the additional light sources 78 may each be in longitudinally successive sections, such as in FIG Fig. 33 shown to be split.

In the second exemplary embodiment, in each case one bus bar 95 is provided on each longitudinal side 32 of the light exit region 31 and, in parallel thereto, in each case. The profile-shaped components 106 are thus in the second embodiment in a symmetrical manner with bus bars 95 and additional light sources 78 fitted.

As in the first embodiment, electrical power is also provided at a voltage of 48 volts by the bus bars 95 in the second embodiment as well. This is done by means of the two conductors 97b, which may be connected to a suitable transformer. Also in the second embodiment, each of the light providing devices 36 and 136 is electrically connected to an associated terminal adapter 199 via an electric wire 85, each in the form of an electric cable. By means of the connection adapter 199, electrical current is tapped from the conductors 97b of the busbar 95. As explained above in detail with regard to the first embodiment, the supply lines 85 are also designed in the second exemplary embodiment such that they can each be magnetically coupled with the channel 3 and in particular with the housing component 104 with the advantages mentioned above.

The connection adapter 199 is in the Figures 30A-G and 31 shown in more detail. The essentially parallelepiped connection adapter 199 has an adapter housing 200 formed as an upper part with an adapter housing part 200a as the upper part and an adapter housing part 200b as the lower part. The adapter housing parts 200a and 200b are each formed with a plastic material. Between the plastic adapter housing parts 200a and 200b, a printed circuit board 191 is clamped. On a printed circuit board 191, in a preferred variant of the second exemplary embodiment, a device 192 can be arranged, which makes it possible to receive control signals for switching and / or controlling the light output of the light providing device 36 or 136 by wireless means. Further devices, in particular a computing device for processing the control signals and / or a driver component to vary the intensity of the light output by the light supply device 36 or 136 in accordance with the control signals, may be provided on the printed circuit board 191. In particular, the device 192 may be a ZigBee module, or the device 192 may be part of such a module disposed on the printed circuit board 191. The device 192 could, however, in one variant, instead of being integrated in the connection adapter 199, be integrated into the light supply device 36 or 136 itself.

The connection adapter 199 is equipped in the region of its one end on the opposite longitudinal sides of the connection adapter 199 with two movable snap hooks 201. Furthermore, an actuating element 203 is provided on the end side in the region of the end of the connection adapter to which the snap hooks 201 are adjacent. By pressing the actuator 203, the snap hooks are retracted or retracted into the adapter housing 200. A suitable mechanism may be provided inside the adapter housing 200. In addition, at the other end of the connection adapter 199, also on the opposite longitudinal sides of the same, in addition two locking lugs 202 from.

The snap hooks 201 and locking lugs 202 form latching devices, which make it possible for the connection adapter 199 latching and releasable again with the profile-shaped Component 106 in the region of the groove 8c to couple. For this purpose, the snap hooks 201 and latching lugs 202 engage behind the beveled ribs 15c 'on their upper side, whereby the connection adapter 199 is held on the component 106, see, for example, US Pat. B. Fig. 23 , If the actuating element 203 is actuated to release the connection adapter 199 from the groove 8c, the snap hooks 201 move into the adapter housing 200 and come out of engagement with the rib 15c '.

The connection adapter 199 can thus be inserted into the groove 8c at any desired arbitrary position along the channel 3 in order to tap current from the busbar 95 and to supply power to a flexibly positionable light supply device 36 or 136. In order to establish electrical contact with the conductors 97b of the busbar 95, the connection adapter 199 has contact elements 204 which are pin-shaped or "pick-off pins", wherein the contact elements 204 after latching attachment of the connection adapter 199 in the groove 8c, respectively one of the conductors 97b in contact.

Fig. 31 also shows the line 85 for supplying the light supply device 36 or 136. The line 85 enters the adapter housing 200 in an inlet region 205, wherein a strain relief for the line 85 is integrated in the plastic adapter housing parts 200a, 200b.

Also in the second embodiment, the lighting assembly 101 may be formed with units 2 having channel sections 3b and busbar sections 95b as well as additional light sources 78 or sections thereof extending in particular over the length of the unit 2, respectively. Also in the second embodiment, the units 2 are connected to each other by means of connecting members 121, 122, for example straight as above with reference to FIGS FIGS. 2, 3 explained.

The connecting members 121 are configured to electrically connect bus bar sections 95b of adjacent units 2 with each other. For this purpose, at a connection point 3c, a connection component 121 is inserted into the groove 8c in such a way that it overlaps the connection point 3c. See for example Fig. 19 and 22 , The connecting member 121 is in the FIGS. 32A-F shown in more detail.

The connecting component 121 has a component housing 220 formed with, for example, two parts, wherein at the four corners of the cuboid connecting component 121 on the longitudinal sides of the same movable snap hooks 221a, 221b are arranged. Furthermore, the connecting member 121 at opposite end-side ends in each case an actuating element 223a and 223b.

For actuation, the actuation elements 223a and 223b, similar to the actuation element 203 of the connection adapter 199, can be pressed in, as a result of which the snap hooks 221a, 221b projecting from the component housing 220 without actuation of the actuation elements 223a, 223b can be retracted into the component housing 220. In this case, for example, the actuating element 223a can act on the snap hooks 221a at one end of the component housing 220 and the actuating element 223b on the snap hooks 221b at the other end of the component housing 220.

The snap hooks 221a, 221b in this case form latching devices which make it possible to couple the connection component 121 in a latching and releasable manner with two adjoining sections of a profile-shaped component 106 at the connection point 3c. The snap hooks 221 a and 221 b engage behind the ribs 15 c ', whereby the connecting member 121 is held at the portions of the component 106. By actuating the actuating elements 223a, b, the snap hooks 221a, b can be pulled back into the component housing 220, whereby the snap hooks 221a, b are disengaged from the rib 15c 'and the connecting component 121 can be removed again.

In order to produce an electrical coupling of the busbar sections 95b, which meet in the connection point 3c, the connection component 121 has two pairs of contact elements 224a and 224b, see FIG Fig. 32A and 32E , The contact elements 224a, b come into contact with the conductor 97b on insertion of the connection component 121 into the groove 8c on both sides such that the contact elements 224a connect sections of a conductor 97b and the contact elements 224b connect sections of the other conductor 97b over the connection location 3c , For this purpose, the contact elements 224a on the one hand and the contact elements 224b to the other in the component housing 220 electrically connected to each other.

The connecting members 122 are provided for the mechanical coupling of the units 2 and in Figs. 25A-C shown in more detail. The use of the connection components 122 show, for example, the Fig. 19-24 , In particular shows Fig. 20A clearly that each of the profile-shaped components 106 is provided with two further grooves 8e and 8f, the grooves 8e, 8f are each performed undercut, ie the profile of the grooves 8f, 8e is T-shaped or vice versa T-shaped. Except for the orientation of the cross section of the grooves 8 e and 8 f is the same.

The connecting member 122 is formed as a portion of a profile, for example, a metal profile, with a substantially T-shaped cross section, wherein the cross section of the connecting member 122 is selected such that the connecting member can be inserted into the groove 8 e or 8 f. Furthermore, the connecting component 122 has a plurality of, for example four, threaded bores 123 along its longitudinal direction, into which screws 124 can be screwed, see for example FIG Fig. 20A . Fig. 24 , In the second embodiment, at each joint 3c between two units 2, four connecting members 122 are provided for mechanically coupling the units 2, see, for example Fig. 20 wherein each connecting member 122 is inserted into a groove 8e or 8f of one and into a groove 8e and 8f of the other unit 2, respectively.

Of the four connecting members 122 at the joint 3c, two of the connecting members 122 are disposed outside in the transverse direction of the channel 3 and inserted into the grooves 8f. These external connection components 122 are designated by reference numeral 122a, see for example Fig. 19 , Two other of the connecting members 122 are designated by the reference numeral 122b and are disposed inboard in the transverse direction of the channel 3, adjacent to the boundary 33. By means of the screws 124, the connecting member 122 in the groove 8e, 8f attached, for example, be clamped. In the case of the external connection components 122a, it may be provided that the fixation of the connection component 122 takes place only in the corresponding groove 8f of one of the units 2.

It should be noted that the connecting members 122 of the Figs. 25A-C and the connecting members 121 of FIGS. 32A-F can also be set up for an angular coupling of channel sections 3b or busbar sections 95b, for example by angled design of the connection components 121, 122, similar to the connection components 21 ', 22' in FIG Fig. 6 indicated.

In a preferred variant of the second exemplary embodiment, however, in order to implement a course of the channel 3 angled at an angle, such as β = 90 degrees, in addition to rectilinear units 2, a unit 2 'designed as a corner piece is provided with a channel corner section 3d as a further unit , please refer Fig. 44 , In this case, the housing component 104, the profile-shaped components 106 and the sections of the additional light source (s) 78 and the busbar (s) 95 inserted into the latter are already brought into the arrangement bent at the angle β in the unit 2 'designed as a corner piece Service. For example, both bus bar (s) 95 and additional light source (s) 78 pass around the corner through the channel corner section 3d.

In Fig. 44 In each case a rectilinear unit 2 are coupled to the unit 2 'at a respective connection point 3c. This can be done, for example, mechanically by means of the connecting components 122 designed as rectilinear profiles Figs. 25A-C respectively. The electrical coupling of the busbars, in turn, by means of connecting members 121 (in Fig. 44 for the sake of clarity, not shown).

It should be noted that the unit 2 'formed as a corner piece is also formed for another angle β, for example, an angle β of 30 degrees, 45 degrees, 60 degrees, 120 degrees, 135 degrees or 150 degrees, or another desired angle can be.

FIG. 36 shows how in the second embodiment of the invention, the channel 3 can be closed at one of, preferably both, the front-side open ends by means of an Endabschlussstücks 120. The channel sections 3b are provided at their front-side open ends with tabs 125, see Fig. 19-22 wherein the tabs 125 in this case each part of a portion of the housing component 104 are. The Endabschlussstück 120 of Fig. 36 is formed as a sheet metal part and, for example, made of sheet steel, and has lateral tabs 125 ', which are formed and arranged corresponding to the tabs 125 of the housing component 104. By means of the tabs 125, 125 ', the Endabschlussstück 120 can be connected to the housing component 104, such as by means of screws to fasten the Endabschlussstück 120 at the front end of the channel 3.

FIG. 36 further shows that the end termination 120 is provided with through holes 120a through which feed lines 160 for feeding electrical current into the bus bars 95 can be passed through the end termination 120. The feeders 160 may each be provided with a suitable, in Fig. 36 not shown, such as a suitable transformer, be electrically coupled, wherein the power source is outside the channel 3.

At the end located in the interior 5 of each of the feed lines 160, the feed lines 160 are each electrically coupled to a feed component 150. Each of the feed components 150 that are in Fig. 36 are not visible, allows the supply of one of the two bus bars 95 of the second embodiment.

A feed component 150 is in the Figs. 37A to 37G and 38 shown in more detail. Analogous to the connection adapter 199 already explained above, the feed component 150 has a substantially cuboid shape and has a component housing formed with a component housing part 150a as the upper part and a component housing part 150b as the lower part, wherein the component housing parts 150a and 150b are each formed with a plastic material.

Analogously to the connection adapter 199, the feed component 150 is provided with two movable snap hooks 151b in the region of its one end on opposite longitudinal sides. An actuating element 152 is provided on the front side in the region of the end of the feed component 150, to which the snap hooks 151b are adjacent, wherein the snap hooks 151b can in turn be retracted by pressing in the actuating element 152. How In the case of the connection adapter 199, a suitable mechanism can also be provided in the interior of the component housing for the feed component 150 for this purpose. At the other end of the feed component 150 are on the opposite longitudinal sides of the same two locking lugs 151 a from. The snap-in hooks 151b and latching noses 151a form latching devices in order to latch the feed component 150 in a latching and releasable manner to the profile-shaped component 106 in the region of the groove 8c, wherein in turn the snap hooks 151b and latching noses 151a engage behind the ribs 15c '. When the actuator 152 is actuated, the snap hooks 151b are retracted, disengaged from the ribs 15c ', and the feed member 150 can be released from the groove 8c.

The feed member 150 may be inserted within the inner space 5, preferably in the end region of the bus bar 95 and the Endabschlussstück 120 adjacent to the groove 8 c to feed power into the bus bar 95. For this purpose, the feed component 150 has contact elements 154a, b on its underside, wherein each of the contact elements 154a, b comes into contact with one of the conductors 97b of the busbar 95 after engagement of the feed component 150 in the groove 8c. The contact elements 154a, b are coupled in the interior of the feed component 150 in a suitable manner with conductors of the feed line 160 in order to be able to supply the bus bar 95. Fig. 38 shows how the feed line 160 enters the feed component 150 in an inlet region 153, wherein a strain relief for the feed line 160 can be integrated into the component housing parts 150a and 150b.

The construction of a lighting arrangement 1, 101 according to one of the embodiments described above can be carried out in the following way.

First, the required number of sections of the housing component 4 or 104, the required number of sections of the profile-shaped components 6 or 106, the for the channel shape to be realized required connection components 21, 22, 21 ', 22' or 121, 122, and the desired number of light providing means 36 and / or 136, each with a line 85 and a connection adapter 99 or 199.

In this case, the busbars 95 and the additional light sources 78 may already be installed in one or both of the profile-shaped components 6, 106. Alternatively, for example, the additional light sources 78 could be provided separately as part of the kit, which are then still inserted into the receiving area 98.

Channel sections 3b are assembled and formed from the sections of the housing component 4 or 104 and the sections of the profiled components 6, 106 which are fastened together, together with the additional light source installed in the profiled component (s) 6, 106 (n) 78 and bus bar (s) 95, a unit 2. Several units 2 can be pre-assembled in this way. For example, the units 2 may already be provided to a customer in pre-assembled form. If a further unit 2 'with a channel corner section 3d or several units 2' is / are required for the desired channel shape, the unit (s) 2 'is / are preferably also preassembled with bus bar (s) 95 already installed / installed therein and additional / additional light source (s) 78.

End-side ends of units 2, which are to be closed later than frontal ends of the channel 3, are closed with the Endabschlusstücken 20 and 120, respectively. Already now, in the second embodiment, in one of the units 2, which has a Endabschlusstück 120, the or the feed component (s) 150 can be coupled. The feed line 160 or the feed lines 160 may / may be passed through the through openings 120a of the Endabschlussstücks 120 already in this step.

The units 2 provided in this manner with the busbar (s) 95 and optionally additional light source (s) 78 arranged therein can be moved behind the intermediate ceiling 10 and assembled in the manner described below.

Fig. 20 illustrates for the channel 3 of the second embodiment, an entire width B3 of the channel 3. Further illustrated Fig. 20 a height H3 of the channel 3, which from the outside of the ceiling portion 4e vertically to the boundary 33 of the light exit area 31 is measured. In addition, in Fig. 20 a width W of the slot 10a located. A distance of the raw ceiling R from the plate elements 9 of the false ceiling 10 is designated T10 and in Fig. 20 shown shortened. The dimensions B3, H3, T10 and W shows Fig. 1 for the first embodiment, in turn, the distance T10 is shown shortened.

In a suspended intermediate ceiling 10 already fixedly installed on a raw ceiling R, the slot 10a of suitable width W is introduced, e.g. cut, wherein the course of the slot 10a is selected according to the course of the desired light exit region 31. The slot 10a can z. B. in the ceiling area of a room through the entire room or much of the same extend and be straight or one or more times angled. Alternatively, the slot 10a could extend in the wall area.

For mounting the channel 3 behind the false ceiling 10, see Fig. 43 (a) , an example rectilinear unit 2 with one of the wall sections 4a, 4b ahead through the slot 10a in the false ceiling 10 in the space between this and the (in Fig. 43 not shown) raw ceiling R introduced behind the false ceiling 10 rotated by 90 degrees about a longitudinal axis of the unit 2 and from the back, so from the side S ', are placed on the false ceiling 10, see Fig. 43 (b) , For this purpose, the distance T10 in relation to the dimensions of the channel 3, in particular to the width B3, selected such that the in Figs. 43 (a) and (b) shown movement is executable.

Longer and angled channels 3 are placed in several sections behind the false ceiling 10. This is done in such a way that, for example, rectilinear units 2 are successively moved behind the false ceiling 10, in the in Fig. 43 illustrated way. After inserting the units 2 behind the ceiling 10, these are positioned and connected in the region of the connection point 3c. For this purpose, it is possible, for example, to proceed in such a way that before the introduction of a first of the units 2, the connecting components 122 are inserted behind the ceiling 10 into the groove 8e or the groove 8f and fixed in each case by means of the screws 124. Such a prepared first unit 2 is through the slot 10 a behind the Cover 10 brought and on the back z. B. placed in the correct position along the slot 10 a. Subsequently, a unit 2 to be connected thereto is also brought through the slot 10a behind the ceiling 10, this second unit 2 was not provided at the junction 3c with connecting members 122. By a sliding movement of, for example, the second unit 2 along the slot 10a to the other, first unit 2, the connecting members 122 can also be inserted into the grooves 8e, 8f of the second unit 2.

For fixing the units 2 to each other at the connection point 3c, the internal connection components 122b are fixed from the visible side S forth by means of screws 124 also in the groove 8e of the second unit 2. For this purpose, the grooves 8e in the inserted state of the unit 2, see for example Fig. 20 , disposed between the edge 9a and the boundary 33. The external connection components 122a remain fixed only in the grooves 8f of the first of the units 2 and in particular serve to improve the guidance of the units 2 relative to one another.

In the case of an angled channel 3, the unit formed as a corner piece 2 'in an analogous manner as described above for the rectilinear units 2 between the raw ceiling R and the false ceiling 10 can be introduced. The dimensions of the unit 2 ', in particular of the channel corner section 3d, are selected in relation to the distance T10 such that an insertion analog Fig. 43 is possible. The mechanical connection of the unit 2 'with the adjacent units 2, cf. Fig. 44 , takes place analogously to the connection of two rectilinear units 2, as described above, in two connection points 3c.

The channel 3 can be fixed by means not shown holding means to the plate elements 9 of the false ceiling 10. From the visible side S forth, the transition region in the region of the edges 9a of the plate elements 9 up to the boundary 33 of the light exit region 31, see Fig. 20 , filled.

After the units are mechanically fixed to one another, the bus bars 95 can subsequently be electrically connected to one another via the connection points 3c by means of the connection components 21, 21 'or 121. This can be done through the opening 28.

The insertion and adjustment of the light providing means 36, 136 is preferably carried out after the installation of the channel 3 behind the false ceiling 10 from the visible side S forth.

If the installation of the channel 3 with the light sources 78 and busbars 95 is completed in the ceiling 10, in a subsequent step through the opening 28, the desired number of light providing means 36 and / or 136 introduced into the interior 5 and in each case with the channel. 3 coupled as described above. The magnetic coupling by means of the permanent magnets 55 allows the introduced light providing means 36 and / or 136 to be positioned very variably in the inner space 5 and slidably on the channel 3 along its length back and forth and also to rotate until the desired lighting effect through Light output can be achieved by the light exit area 31 to the outside. Further flexibility allows pivoting about the pivot axis 48. For operation, the light providing means 36, 136 are held within the interior 5 by means of magnetic force. The insertion of the light providing devices 36, 136 and their arrangement in the interior 5, as well as the coupling and adjustment can be carried out through the opening 28 therethrough.

When installing the channel 3 behind the false ceiling 10 is also ensured that the bus bars 95 are connected by means of the feed lines 160 to a power source, such as a transformer, or can be connected. The light supply devices 36, 136 can be supplied in a particularly simple and flexible manner with the aid of the busbars 95 arranged on both sides of the light exit region 31 in the second exemplary embodiment. The respectively provided connection adapter 199 can after mounting the channel 3 with the / the busbar (s) 95 and possibly the / the additional light source (s) 78 behind the false ceiling 10 through the opening 28 at a freely selectable location with one of the bus bars 95th depending on the desired placement of the light supply device 36 or 136 on one or the other side of the light exit region 31, be coupled for tapping current. For example, in the case of the light-providing device placed on the left-hand side, the left side of the central axis M may be provided Conductor rail 95, at the right positioned light providing device the right side of the central axis M provided busbar 95 are used for supply. Thus, even with long channels 3, for example a channel 3 with a length of several meters, nevertheless short paths are created, which are bridged by the line 85. The supply line 85 located in the inner space 5 is neatly arranged and guided by magnetically adhering the lead 85 to the housing component 4 or 104 within the inner space 5, without sagging or disturbing. The switching and / or control of the light output of the light providing devices 36, 136 takes place wirelessly with the aid of the device 192, in particular using the so-called ZigBee specification. A complicated wiring for the purpose of controlling the light providing means 36, 136 is avoided in this way and created a very flexible controllable lighting arrangement 1, 101.

A lighting arrangement 101 'according to a variant of the second embodiment is shown in FIGS FIGS. 45 and 46 illustrated and differs only in the differences described below from the lighting assembly 101. In the lighting assembly 101 'are at intervals along the channel 3 holding devices 107 attached thereto. The holding devices 107 are provided for fastening the channel 3 to the solid, load-bearing raw ceiling R. The holding devices 107 are formed as angle pieces and firmly connected by means of the screws 14 with the channel 3. To attach the channel 3 to the raw ceiling R are in addition, see Fig. 46 Ropes 117 are provided, of which Fig. 46 just one example shows. About the ropes 117 and the holding devices 107, the channel 3 is suspended from the raw ceiling R. In this way, the plate elements 9 can be relieved. Although the profile-shaped components 6 can sit on the plate elements 9, at least part of the weight of the channel 3 and the components coupled thereto are supported directly on the raw ceiling R. The holding devices 107 and ropes 117 may be provided as part of the kit, wherein holding devices 107 may already be attached to the channel 3.

Some other modifications of the second embodiment schematically illustrate the Figs. 39A-B, 40A-B, 41A-B and 42A-B ,

In the lighting arrangement 301 according to the modification of Figs. 39A, 39B For example, instead of light providing means 36, 136, two light supplying means 336a and 336b are provided, and both are arranged in the inner space 5 to discharge light L through the light exit area 31 to the outside. The light supply device 336a has an overall linear elongated, cuboid shape, wherein the light providing means 336a on its in Fig. 39A the light exit region 31 facing side a plurality of individual light emitting areas 336a 'has. The light supply device 336a is coupled to the channel 3 and the electrical power supply and the control / circuit are the same as in the light supply devices 36, 136. However, the light supply device 336a is not adjustable in itself beyond the positionability by means of the magnetic coupling and radiates in Fig. 39A Directed light vertically through the light exit region 31 downwards. In dash-dotted lines is in Fig. 39A Furthermore, it is indicated that the light supply device 336a could also be positioned centrally above the light exit region 31.

A longitudinal extent L of the light supply device 336a is greater than the width B of the light exit region 31. In parallel alignment of the elongated shape of the light providing device 336a to the light exit region 31, this can be introduced from the visible side S in the interior 5, wherein the light providing means 336a in Fig. 39B in the coupled state also extends parallel to the light exit region 31 above the same.

The light supply device 336b has a functional section 345 formed with a linearly elongate, parallelepipedal shape, wherein a longitudinal extent L of the parallelepipedal shape clearly exceeds the width B of the light exit region 31. The light supply device 336b further has a base section 346 which is pivotably coupled to the functional section 345, whereby the emission direction of the light supply device 336b can be adjusted similarly to the light supply devices 36 or 136.

Also, the light providing device 336b can be in parallel alignment of the elongated shape to the light exit region 31 from the visible side S in the interior 5 are introduced. Fig. 39B shows the alignment of the elongated shape parallel to the light exit region 31 in the coupled state, wherein the functional portion 345 for the directed delivery of light L through the light exit region 31 is pivoted outwardly, see Fig. 39A , The light supply device 336b could alternatively be coupled to the channel 3 in the wall region 5a or 5b.

The light providing means 336a and / or 336b may also be combined with a light providing means 36 and / or 136 in the same lighting arrangement. For precise positioning, the light supply devices 336a, 336b can also be slid on the channel 3 and possibly rotated.

In Figs. 40A-B, 41A-B and 42A-B additional light providing means 437, 537 and 637 are shown schematically. In the the Figs. 40A-B, 41A-B respectively. 42AB corresponding modifications of the second embodiment, the additional light providing means 437, 537 and / or 637 may be provided in any combination in addition to at least one of the light providing means 36, 136, 336a and / or 336b to supplement the lighting effects achieved. The Figs. 40A-B, 41A-B and 42A-B thus illustrate lighting arrangements 401, 501 and 601, respectively, according to the respective modifications of the second embodiment.

The additional light providing device 437 is arranged in the inner space 5 and magnetically coupled to the housing component 104 in order to hold the additional illumination device 437 on the channel 3, analogous to the magnetic coupling described above for the light supply devices 36 and 136. For the power supply of the additional light providing device 437, this is likewise, like each of the light supply devices 36, 136, 336a-b, via a line 85 and a connection adapter 199 (in FIG Fig. 40A-B not shown) with one of the two bus bars 95 electrically coupled.

The additional light providing device 437 has a linear elongated, cuboid-shaped shape with a longitudinal extent L ', see Fig. 40B , where one Width B 'of the additional light providing device 437 in Fig. 40A-B is less than the width B of the light exit area 31, see also Fig. 20 , The additional light providing device 437 can therefore be located laterally of the center of the light exit region 31 or, as in FIG Fig. 40A shown with dotted line, be placed centrally with respect to the width direction of the light exit area 31. The additional light providing device 437 is flush with the panel elements 9 of the ceiling 10 on the visible side S and emits light L directed into the room. Alternatively, the width B 'could substantially correspond to the width B, whereby then the additional light providing means 437 over the longitudinal extent L' substantially fills the light exit region 31.

The additional light providing device 537 of Fig. 41A-B is designed to irradiate a wall, and thus designed as a "wallwasher". For this purpose, the additional light providing device 537 is in the in Fig. 41A-B shown coupled with the channel 3 state from the interior 5 through the light exit region 31 outward, thus in this state, only the upper portion of the additional light providing means 537 is received in the interior 5. Fig. 41A FIG. 12 shows that the additional light providing means 537 irradiates light L outside the interior space 5 laterally toward a wall. The additional light providing device 537 is magnetically coupled to the channel 3 in the same way as the additional light providing device 437 and, like the light providing devices 36, 136, is also supplied with power via a line 85 and a connection adapter 199.

The additional light supply device 537 has a linearly elongated, parallelepiped-like shape with a longitudinal extension L '. A width B 'of the additional light supply device 537 may again correspond to the width B of the light exit region 31, in which case the additional light supply device 537 substantially fills the light exit region 31, or be smaller than the width B, see Fig. 41A ,

The additional light providing device 637 of Fig. 42A-B is provided with an opal light emitting area 638 located in the one coupled to the channel 3 and in Fig. 42A-B illustrated state of the additional light providing device 637 outside the interior 5 is located. Thus, the additional light providing means 637 is in the state of Fig. 42A-B through the light exit region 31 from the interior 5 out. The opal light exit region 638 supplements the light effects made possible, for example, by the light supply devices 36, 136, in an aesthetic manner by an element which shines evenly in the ceiling region. The additional light providing device 637 is also magnetically coupled to the channel 3 in the same way as the additional light providing device 437, and the electrical power supply takes place, as in the case of the light supply devices 36, 136, via a line 85 and a connection adapter 199.

The additional light-providing device 637 likewise has a linearly elongate, parallelepiped-like shape with a longitudinal extension L ', in which Fig. 42AB a width B 'of the additional light providing device 637 corresponds to the width B of the light exit region 31 and this is thus substantially filled in the width direction by the additional light providing device 637. However, widths B 'smaller than the width B are conceivable.

The control or switching of the additional light providing devices 437, 537 or 637 takes place, as described above for the light providing devices 36 and 136, preferably wirelessly with the aid of the ZigBee specification. It is understood that the modifications according to the Figs. 39A-B, 40A-B, 41A-B and 42A-B are analogously applicable to the first embodiment.

Lighting arrangements 301, 401, 501 or 601 can be constructed analogously to the above explanations for the lighting arrangements 1, 101, wherein alternatively or additionally the light providing means 336a and / or 336b is / are included in the respectively provided kit and / or additionally one or more a plurality of the additional light providing means 437, 537, 637 is or are included. The additional light supply devices 437, 537 and 637 can each also be introduced after completion of the channel 3 from the visible side S through the light exit region 31, wherein in these cases for precise positioning, the respective additional light providing device 437, 537, 637 can be slidably moved on the channel 3, in particular also along the longitudinal direction 3a.

It should be noted that, in all the above-described embodiments, each of the light providing devices 36, 136 in accordance with FIGS Fig. 7-15 respectively. Fig. 26-29 may be formed and preferably includes one or more LEDs as light sources. However, it is conceivable that the light providing devices 36, 136 generate light in a different way, wherein any bulbs can be used. Instead of LEDs, for example, incandescent lamps and / or halogen lamps and / or other suitable lamps or light sources could be provided. Also, the light providing means 336a, 336b and the additional light providing means 437, 537, 637 may each include one or more LEDs as light sources, or may include incandescent and / or halogen lamps and / or other suitable bulbs or light sources.

Although the present invention has been fully described above with reference to preferred embodiments, it is not limited thereto, but modifiable in a variety of ways.

For example, the invention is not limited to lighting arrangements in which the light exit area and / or the channel extend in a straight line or in pieces rectilinearly. In variants of the invention, the channel and / or the light exit region can extend in a curved manner at least in sections in the longitudinal direction of the channel or the light exit region and / or be branched.

For example, according to the shape of the profile-shaped components 6, and the shape of the base surface of the housing component 4 or 104, respectively curved and / or branched as needed. The housing component 4 or 104 could therefore be executed in variants with, for example, partially curved wall surfaces. In a case in which the housing component 4 or 104 has curved wall sections, at least one planar inner surface area 5e may be provided on the ceiling of the housing component 4, 104 for a simple coupling of the light providing devices to the channel.
