Description

FIELD OF THE INVENTION

The invention relates to a lighting system.

TECHNICAL BACKGROUND

The applicant is aware of a lighting system which comprises a channel and light inserts which can be inserted into the channel. In this system, a busbar is integrated in the duct. In this case, a busbar connector is provided for connecting the busbars of sections of the channel arranged in succession. In the system known to the applicant, the dimensioning takes into account the space required for wired control of the lighting inserts via control lines by means of the so-called DALI system, which is also known.

In this known solution, however, it is not possible to realize continuous, and in particular long, aesthetically pleasing light strips with a simultaneously low installation depth or "system height" and also a small installation width or "system width".

This is a condition that needs to be improved.

In the US 2016/0195250 A1 a line-like lighting device is described. A contact element is arranged on a surface of a lighting module, while a rail housing has a power connection to provide current for the lighting module. The rail housing can be designed by connecting a plurality of frames together along a line of the desired length. A connector is described which electrically connects the power connections of adjacent frames. A first surface of the power connection, with which one end of the contact element of the lighting module comes into contact when the lighting module is inserted into a receiving area of the rail housing, lies through an opening groove the recording area freely. The contact element can also be displaced along the opening groove in a connection region of the frame. The US 2015/226384 A1 describes a generic lighting system.

SUMMARY OF THE INVENTION

Against this background, the invention has for its object to provide a lighting system that can be made particularly slim, and that makes it possible to create continuous aesthetic light strips with a small installation depth and narrow installation width.

According to the invention, this object is achieved by a lighting system having the features of claim 1.

The idea on which the invention is based is that it is possible to create continuous light strips, even those of great length, with the aid of lighting units which can be inserted into the channel if the channel, the connector and the lighting unit are set up as components of the lighting system in such a way that that in an operational state, that is to say when the lighting unit and the connector are inserted into the channel, the lighting unit and connector can overlap within the channel. In this way it is also possible to achieve a low "system height" and "system width", in particular small widths and heights of the channel. At the same time, the proposed lighting system with the busbar provided in the interior of the channel enables flexible and versatile lighting solutions; in particular, the busbar can serve to supply various types of lighting inserts that can be used in the channel.

According to the invention, the lighting unit has a light supply and optics unit and at least one supply unit. Here, the supply unit has contact devices by means of which the electrical coupling of the lighting unit to the busbar is made possible. Furthermore, the supply unit is electrically coupled to the light supply and optics unit. The supply unit also has a housing element which is mechanically coupled to the light supply and optics unit. In this way, for example, standardization of the supply unit for differently designed lighting units can advantageously be achieved. For example, it can thus be provided that lighting units of different types each have an identically designed supply unit, but differently designed light supply and optical units. Also, for example, lighting units of different lengths along their longitudinal direction could advantageously have identically designed supply units, with a longer lighting unit having several identically designed supply units, while short lighting units could each have only one such supply unit. The mechanical coupling of the supply unit by means of its housing element to the light supply and optical unit enables a reliable connection between the two units.

According to the invention, the housing element of the supply unit projects in a direction that extends parallel to a depth direction of the channel in the inserted state of the lighting unit, essentially as far beyond the light supply and optical unit as a housing of the connector extends in a thickness direction of the connector. In this way, the space available in the channel, in particular in its interior, can be used particularly well, at the same time allowing the lighting unit to overlap with the connector.

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

In one configuration, the lighting system further comprises the at least one lighting unit. Here, the channel, the lighting unit and the connector are designed such that the lighting unit is completely or at least substantially completely in the channel when inserted and overlapping with the connector is recordable. Such a lighting system is particularly slim and discreet. A lighting unit that is completely accommodated in the duct can appear particularly aesthetically pleasing.

In a development of the invention, the lighting unit and the channel can be designed such that the lighting unit is arranged in the inserted state flush with the opening of the channel. Alternatively, in a further development, the lighting unit and the channel can be designed such that the lighting unit in the inserted state is set back into the interior of the channel relative to the opening of the channel. Both in the flush and in the recessed case, the lighting unit can thus be completely accommodated in the channel. Both a flush and a recessed arrangement can be aesthetically pleasing.

In a further embodiment of the invention, the lighting system further comprises the at least one lighting unit, the channel, the lighting unit and the connector being designed such that the lighting unit protrudes from the opening of the channel when inserted and overlapping with the connector. However, it should be pointed out that in this case, too, the light unit can overlap with the connector within the channel when it is inserted into the channel. With the light unit protruding from the opening of the channel, another aesthetic effect can be achieved.

In particular, it is possible in each case with the lighting unit arranged flush with the opening of the channel, which is set back relative to the opening of the channel and the light unit protruding from the opening of the channel, to produce continuous light strips, in particular without poorly illuminated joints.

According to a further embodiment of the invention, the channel and the lighting unit are designed in such a way that the lighting unit in the inserted state essentially fills the channel in the transverse direction of the channel at least on one visible side thereof. With a slim lighting system with a comparatively small installation width, effective lighting can advantageously be achieved with such a configuration. The available system width is advantageously used in this embodiment for the accommodation of the lighting unit.

In a further embodiment, the lighting system comprises at least two of the lighting units, each of which can be arranged to overlap with the connector within the channel in such a way that end sections of the lighting units overlapping with the connector essentially adjoin one another at the end face and in particular at least partially, preferably essentially completely, the connector , cover up. With this configuration, it is thus possible to produce aesthetic, continuous light strips, to avoid unlit areas in the system, and advantageously to hide the connector behind the lighting units.

In a further embodiment, the lighting unit is designed as a linear, elongated unit. In this case, the lighting unit is designed in particular to form a continuous light band with at least one further linearly elongated lighting unit when in use in the channel.

In a preferred development, the length of the lighting unit along a longitudinal direction thereof is at least ten times the width of the lighting unit, the width being taken in a direction extending transversely to a depth direction of the channel when the lighting unit is in use.

In particular, the length of the lighting unit can be at least 20 times, at least 40 times, at least 60 times or at least 80 times the width of the lighting unit.

In a further embodiment, light can be emitted during operation by the lighting unit in a light exit area that extends essentially over the entire length of the lighting unit. This means that the entire length of the lighting unit can be used to emit light, and dark areas of the light band are avoided.

According to a further embodiment, the lighting unit can be coupled to the channel for holding the same. The lighting unit can thus be held in a defined manner for its attachment. In particular, the lighting unit can be magnetically coupled to the channel. A magnetic coupling offers great flexibility in the arrangement of the lighting unit in the channel. Furthermore, the lighting unit can be held reliably by magnetic means. The magnetic coupling can be brought about and released easily and without tools by an operator.

In particular, in one configuration, the channel can be equipped with at least one ferromagnetic element in order to enable the magnetic coupling of the lighting unit to the channel.

In one embodiment of the invention, the channel is formed with at least two sections, the sections of the channel meeting at a joint and each having a busbar section, and the connector also enables electrical coupling of the busbar sections across the joint. The connector can in this case, in particular, electrically couple the busbar sections of rectilinear sections of the channel which adjoin one another in a rectilinear or angled manner. For this purpose, the connector can in particular have contact elements which can each be brought into contact with a conductor of one of the busbar sections in order to effect the electrical coupling of the busbar sections.

In one embodiment, the sections of the channel are each formed with an extruded profile body, in particular an extruded profile made of aluminum or an aluminum alloy.

In embodiments of the invention, the duct can be used as an installation duct, in particular for installation in a wall or a ceiling, as a built-up duct, in particular for mounting on a wall or on a ceiling, or as a duct for suspended mounting, in particular on a Blanket. As a built-in duct, the duct can be set up, in particular, for a preferably rimless and / or flush installation in a plasterboard ceiling or plasterboard wall. In a preferred development of the invention, the sections of the channel can be put together to form a channel of any length, the electrical coupling of the busbar sections of adjoining sections of the channel taking place in each case by means of a connector. If necessary, the lighting system can thus have a large number of connectors. It is thus possible to create lighting solutions for rooms of various sizes using the proposed lighting system.

The mechanical coupling of the connector to the sections of the channel also enables additional mechanical alignment and guidance of the sections of the channel adjoining one another at the joint. Additional elements for mechanical guidance are therefore not necessary. The connector can advantageously enable the electrical coupling of the busbar sections with a small space requirement, as well as provide mechanical guidance for the adjoining sections of the channel. This also helps to make the lighting system slim, with a small installation width and a low installation height.

In one embodiment, the supply unit is connected to the light supply and optics unit in a latching manner. In particular, it can be provided that the housing element of the supply unit is provided with locking devices for this purpose. The connection of the supply unit with the light supply and optical unit can thus be accomplished in a simple and reliable manner. A connection of the supply unit to the light supply and optical unit via latching devices on the housing element of the supply unit can also be inexpensive.

In a preferred embodiment, it is provided that the lighting unit, when inserted in the channel, can be arranged such that it overlaps with the connector used for coupling the busbar sections in such a way that the light supply and optical unit overlaps with the connector while there is no overlap the supply unit occurs with the connector. This in turn enables a good use of the available space.

In one configuration, the lighting unit, in particular the light output thereof, and preferably its intensity, can be switched and / or controlled wirelessly.

In a preferred embodiment, the lighting unit is wirelessly switchable and / or controllable, for which purpose the supply unit has a module by means of which control signals for switching and / or controlling the light output of the light supply and optical unit, in particular its intensity, can be received wirelessly, the Module is preferably received in the housing element of the supply unit.

With the help of a wireless control of the lighting unit, or a wireless switching of the lighting unit, the installation depth and the installation width of the lighting system can advantageously be kept small. The space required when using control lines for wired control of lighting units can be avoided with the help of the wireless switching and / or controllability of the lighting unit. Extensive contact devices or connections for control lines, such as for the so-called DALI system, are avoided, and thus both the supply unit and the connector can be designed to be particularly slim.

In particular, the control signals for switching and / or controlling the light output of the light supply and optical unit can be radio signals.

In a further embodiment of the invention, the supply unit is designed as a holding unit for the lighting unit for holding the lighting unit in the channel. It can in particular be provided that the supply unit contains magnets, preferably permanent magnets, for the mechanical coupling of the lighting unit to the channel. The function of holding the lighting unit can thus advantageously be formed on a standardizable supply unit regardless of the special configuration of the light supply and optical unit. The advantages of magnetic coupling to the channel have already been explained above. Magnetic coupling using permanent magnets can be implemented in a particularly simple manner.

In particular, the housing element of the supply unit can additionally accommodate the magnets.

In one embodiment, the extension of the lighting unit in a direction that is parallel to the depth direction of the channel in the inserted state of the lighting unit is less than or equal to the width of the lighting unit in a direction transverse to the depth direction of the channel. This in turn can contribute to a space-saving and aesthetic design of the lighting system.

According to a further embodiment, in a direction that extends transversely to the depth direction of the channel in the inserted state of the lighting unit, the width of the supply unit is at least 80%, preferably at least 90%, of the width of the light supply and optical unit. In particular, in a direction that extends transversely to the depth direction of the channel in the inserted state of the lighting unit, a width of the housing element of the supply unit can be at least 80%, preferably at least 90%, of a width of the light supply and optics unit. In this way, the space available in the interior of the channel can be used even better, which in turn has an advantageous effect on the space requirement, in particular for example the installation depth, of the lighting system.

In particular, the width of the housing element of the supply unit can essentially correspond to the width of a connector housing of the connector.

According to a further embodiment, it is provided that in a direction that extends parallel to the depth direction of the channel in the inserted state of the lighting unit, the light supply and optical unit has a height of approximately 13 mm to approximately 20 mm, preferably approximately 14 mm or in about 19 mm, for example 14.1 mm or 14.3 mm or 19 mm, and / or that in a direction that extends transversely to the depth direction of the channel in the inserted state of the lighting unit, the light supply and optical unit has a width from about 24 mm to about 28 mm, preferably in about 25 mm or in about 27 mm, for example 25.4 mm or 27.2 mm, and / or that the channel at least in an area in which, when the lighting unit is inserted, the light is provided - And optical unit is housed, has an inner width of about 27.5 mm to about 28.5 mm, preferably substantially 28 mm. Such a lighting system is particularly slim and space-saving.

According to a further embodiment, it is provided that in a direction that extends parallel to the depth direction of the channel in the inserted state of the lighting unit, the lighting unit has a height, measured over housing components of the lighting unit, of approximately 19 mm to approximately 27 mm, preferably approximately 20 mm or approximately 21 mm or approximately 25 mm, for example 20.3 mm or 20.5 mm or 25.2 mm, and / or that the channel has a depth available for receiving the lighting unit of approximately 19 mm to approximately 22 mm, preferably approximately 20 mm or approximately 21 mm, for example approximately 20.5 mm.

According to a further embodiment, the lighting unit has a linearly elongated lens. By means of the linearly elongated lens, it can in particular be ensured that the desired light image, for example a light image that is as homogeneous as possible over the length of the light unit, and the desired light distribution are achieved along the lighting unit.

In a further embodiment, the light supply and optics unit has a housing component in which the lens and an LED circuit board are accommodated. Here, the housing component of the light supply and optics unit is mechanically coupled to the housing element of the supply unit. In this way, for example, the lens and the LED circuit board can be held securely via the housing component and can thus also be coupled to the supply unit. In addition, for example, the lens, the LED circuit board and the housing component can be preassembled together to form an easily manageable light supply and optics unit and only then mechanically coupled to the supply unit. The LED board and the lens can be protected by means of the housing component. In further developments, the housing component can be made translucent or opaque, depending on which aesthetic effect is to be achieved.

In a further embodiment of the invention, the lens has an essentially constant cross section along a longitudinal direction of the lens. In particular, the extension of the lens in a direction that is parallel to the depth direction of the channel in the inserted state of the lighting unit is less than in a width direction the lens across the depth direction of the channel. A lens designed according to this configuration with an essentially constant cross section can be produced in a comparatively simple manner. A lens which, in accordance with this embodiment, has a width transverse to the depth direction of the channel, which is greater than its height parallel to the depth direction of the channel, in turn advantageously contributes to a space-saving lighting system with a small installation depth.

According to a further embodiment, the connector has movable snaps. The channel is provided with longitudinal ribs in the interior, the catches of the connector being designed to engage behind the longitudinal ribs for a latching coupling of the connector to the sections of the channel, and the catcher also being operated by an operator by actuating one or more actuating elements can be brought out of engagement with the longitudinal ribs to release the coupling. This enables a reliable mechanical coupling of the connector to the sections of the channel with a small size.

In embodiments of the invention, the at least one lighting unit which can be arranged to overlap with the connector within the channel can be designed in various ways, for example as a lighting unit for diffuse lighting or a lighting unit for focused lighting. In this way, a wide variety of lighting requirements can be taken into account.

Furthermore, in further refinements of the lighting system according to the invention, it can be provided that the lighting system has additional lighting inserts, the additional lighting inserts being insertable into the channel and being electrically coupled for their supply to the power rail. Such an additional lighting unit can be designed, for example, as a spot, as a pivotable spot, as a suspended spot, as a wall washer, as a linear arrangement of spots or as a linear, diffusely radiating light insert. In a further embodiment, the additional lighting unit can be designed with a pendant lamp.

The above refinements and developments can, if appropriate, be combined with one another as desired. Further possible refinements, developments and implementations of the invention also include combinations of features of the invention described above or below with reference to the exemplary embodiments, which are not explicitly mentioned. In particular, the person skilled in the art will also add individual aspects as improvements or additions to the respective basic form of the present invention.

DESCRIPTION OF EMBODIMENTS

Fig. 1-3 show a lighting system 1 according to a first exemplary embodiment, which has a channel 3 formed with sections 2, lighting units 4 and a connector 5. The channel 3 is formed in such a way that the sections 2 are assembled on their end faces in an abutment 6 adjacent to one another. In this way, a channel 3 of great length can be created from shorter, more manageable sections 2. The channel 3 can be formed with two or more sections 2.

The length of a section 2 is in Fig. 2 designated L2, whereby sections 2 of different lengths L2 can be used. For example, 3 sections 2 with L2 = 1000 mm or L2 = 2000 mm or L2 = 3000 mm could be available to set up the channel. An individual cut to a selectable length L2 is conceivable.

The sections 2 are each formed with an extruded profile body 7, for example made of aluminum or an aluminum alloy, and a busbar section 8 which is preferably fastened in a latching manner therein. The busbar sections 8 and the sections 2 preferably have essentially the same length L2. In an inner region 9 of the channel 3, the channel 3 thus has a busbar 10 which forms part of the channel 3 and is formed with the busbar sections 8 adjoining each other at the joint 6.

The channel 3 can be permanently installed, for example without a rim, in a plasterboard ceiling or wall not shown in the figures. The channel 3 can thus be approximately flush with a ceiling level E after installation. This is in Fig. 3 exemplarily sketched. The channel 3 can thus be designed as an installation channel for installation in a wall or ceiling. Additionally or alternatively, the channel 3 can be designed as a built-up channel, in other words, the channel 3 can be firmly mounted on a wall or ceiling, not shown in the figures. In addition, the channel 3 can additionally or alternatively be set up to be suspended from a ceiling.

The lighting units 4 and the connector 5 can each be inserted into the channel 3, thus the channel 3 receives the lighting units 4 and the connector 5. The busbar 10 is set up to supply the lighting units 4 used in the channel 3 with electrical current for their operation, for example at a voltage of 48 volts. For this purpose, the lighting units 4 can each be electrically coupled to the busbar 10.

The lighting units 4 are each linearly elongated and set up to form a continuous light band together in their state in the channel 3 during operation. The length of the lighting unit 4 is designated L4, see Fig. 1 , The light band generated experiences essentially no interruption in the area of the joint 6, it acts continuously and aesthetically without conspicuous non-luminous areas. The number of lighting units 4 can vary depending on the total length of the channel 3 and the length L4 of the individual lighting units 4.

The busbar 10, formed with the busbar sections 8, is arranged in the region of a base of the channel 3, see Fig. 3 , wherein a base body 19 of the busbar section 8 has latching elements 16 which engage behind rib-like undercuts 17 on both side walls 18 of the profile body 7 in order to hold the busbar sections 18 in the profile body 7. The base body 19 is formed with a plastic material and receives two electrical conductors 20 for providing the electrical current.

A current flow in the busbar 10 over the joint 6 is made possible in that the adjacent busbar sections 8 are electrically coupled to one another at the joint 6 by means of the connector 5 inserted into the channel 3 become. Depending on the number of sections 2 and joints 6, several connectors 5 can be used.

Each of the lighting units 4 Fig. 1 has a flat supply unit 11 and a light supply and optics unit 12. The supply unit 11 is mechanically coupled to the light supply and optics unit 12. Here, the supply unit 11 has a housing element 13 which is equipped with latching devices 14. By means of the locking devices 14, of which in Fig. 1 For the sake of a better overview, only a few are provided with reference numerals, the supply unit 11 is connected to the light supply and optical unit 12 in a latching manner and is thus mechanically coupled.

The lighting units 4 each have a light exit area 15, which in Fig. 2 for a lighting unit 4 is indicated in dotted lines and extends essentially over the entire length L4 of the lighting unit 4 and also essentially over its entire width transverse to the longitudinal direction L '. In the light exit area 15, the lighting unit 4 can emit light during operation.

Fig. 3 shows one of the lighting units 4 in its state inserted in the channel 3 in more detail. The lighting unit 4 in Fig. 3 has a light supply and optics unit 12, which in turn has a translucent, opal housing component 21. The housing component 21 is closed on the side of the light exit region 15, is provided with an interior space 22, and is provided with an opening 23 on a side facing the supply unit 11.

The mechanical coupling of the supply unit 11 with the light supply and optics unit 12 is accomplished in such a way that the latching devices 14 engage bevelled ribs 27, which are provided on both sides of the housing component 21 and project laterally from the housing component 21, and thus the housing element 13 couple mechanically with the housing component 21.

Inside the housing component 21 is an LED board 24 with light-emitting diodes or LEDs 25, of which in Fig. 3 only one LED 25 is visible, added. On The LED circuit board 24 can optionally be arranged further electrical and / or electronic components necessary for the operation of the LEDs 25.

Furthermore, the housing component 21 receives a linearly elongated lens 26. At the in Fig. 3 The embodiment shown is that in Fig. 3 Lens 26 shown in cross section with a lens along its longitudinal direction, which is parallel to the longitudinal direction L of the lighting unit 4 (see Fig. 1 ) runs, constant cross section formed. The lens 26 is equipped on a side facing the LED circuit board 24 with a recess 28 which receives the LEDs 25. The lens 26 is in cross section with narrow edge regions 29, which are held together with the LED circuit board 24 by ribs 30 of the housing component 21 projecting into the interior 22, and a thicker central region 31, which towards the light exit region 15 is not completely filled Interior 22 protrudes into it. The central region 31 is rounded in the cross section of the lens 26 on both sides of the center and is formed in a central part on a side of the lens 26 facing away from the LED circuit board 24 with a shallow recess 32. With the aid of the shape of the lens 26, an advantageously homogeneous light distribution on the light exit area 15, formed by an area of the opal housing component 21 that is visible from the outside on the visible side S, is achieved.

The LED circuit board 24 is supplied with electrical current through the opening 23. For this purpose, contact elements 33 are provided which enable an electrical coupling of the LED board 24 of the light supply and optics unit 12 to the supply unit 11.

Fig. 3 illustrates that in the first exemplary embodiment, the lighting unit 4, in the state inserted into the channel 3, is essentially completely accommodated in the channel 3, in other words, within the inner region 9 thereof. The housing component 21 can be flush with the edges 34 'of an opening 35' of the channel 3 or protrude slightly, for example by a few tenths of a millimeter, over the edges 34 '. The opening 35 ', which is formed between the side walls 18 of the profile body 7, is in the embodiment of the Fig. 3 essentially filled by the light supply and optics unit 12 of the lighting unit 4. Thus, through the lighting unit 4, the channel 3 on a visible side S, in particular in a transverse direction Q of the channel 3, essentially filled, wherein in Fig. 3 the lighting unit 4 occupies most of the interior 9.

Fig. 4 shows the lighting system 1 of FIG Fig. 1 in a longitudinal central section, the channel 3 being shown in section, but the lighting units 4 and the connector 5 are shown in uncut. A detail X in the area of the joint 6 shows Fig. 5 , Another detail Y in the area of a supply unit 11 shows Fig. 6 ,

In the state used in channel 3, corresponding to the state of Fig. 2-6 , each of the two lighting units 4 overlaps within the channel 3 with the connector 5, which is also used for the electrical coupling of the busbar sections 8 in the channel 3, see Fig. 5 , Specifically, one end section 34 of each of the two lighting units 4 overlaps with the connector 5 in such a way that the end sections 34 directly adjoin one another in the longitudinal direction of the channel at the location of the joint 6 on end faces 35 of the lighting units 4.

Seen from the visible side S of the channel 3, the lighting units 4 and thus the lighting system 1, the connector sections 5 are essentially completely covered by the end sections 34.

A length L11 of the supply unit 11 is significantly less than the length L4 of the lighting unit 4. For example, in FIG Fig. 1-6 : L11 ≤ (L4 / 2). Like the length L4, the length L11 is taken along the longitudinal direction L of the lighting unit 4. By way of example and preferred, L11 = 148.4 mm.

Thus, the end sections 34 overlapping with the connector 5 form parts of end sections 36, in which the light supply and optical unit 12 protrudes in the longitudinal direction L 1 above the supply unit 11, see Fig. 1 and Fig. 4 , Fig. 1 also shows that, in the first exemplary embodiment, the supply unit 11 is centered in the longitudinal direction L 'on the light supply and optical unit 12, and that an end section 36 of the light supply and optical unit 12 thus protrudes in the longitudinal direction L' on both sides of the supply unit 11.

By overlapping the lighting units 4 and the connector 5 within the channel 3, continuous light strips can be created without unlit areas, even if the channel 3 is composed of several sections 2. The lighting unit 4 can thus sit with parts of the end sections 36 above the connector 5, the lighting unit 4 and the connector 5 not being directly connected to one another. The lighting unit 4 can rest lightly on the flat connector 5 or a small gap can be formed between the lighting unit 4 and the connector 5 in the section 36. The connector 5 is shorter in the longitudinal direction L 'than the supply unit 11, that is to say L5 <L11.

The lighting unit 4 is in the Fig. 7-9 shown separately. In cross section of the Fig. 9 additional internal components of the supply unit 11 can be seen. Further features of the supply unit 11 are in the Fig. 10-14 shown.

The supply unit 11 has contact devices 36 'which are in Fig. 9 are designed like a pen. The contact devices 36 'are provided in each case to be brought into contact with one of the conductors 20 and thereby to enable the electrical coupling of the lighting unit 4 to the busbar 10.

Inside the housing element 13, see Fig. 9 and Fig. 14 , a circuit board 37 is added. The circuit board 37 is held in the housing element 13 by means of locking elements 39 and rests on shoulders 40 of the housing element 13.

The contact devices 36 'are connected to the circuit board 37. In addition, a module 41 is provided on the circuit board 37, in particular realized as a component of the circuit board or arranged on it, the module 41 being set up to wirelessly transmit control signals for switching and / or controlling the light output of the light supply and optics unit 12 to the lighting unit 4 receive. In this way, wireless switchability and / or controllability of the light output of the lighting unit 4, in particular dimming, is made possible. Additional devices or components can be provided on the circuit board 37 in addition or as part of the module 41 in order to process and / or evaluate the received switching and / or control signals and, as a function of the switching and / or control signals, transmitted via the contact elements 33 of the LED board 24 electrical current to provide for the operation of the LEDs 25. In this way, the light supply and optics unit 12 is thus supplied with current as a function of wireless switching and / or control signals, which can in particular be radio signals. The module 41 can in particular be designed as a so-called ZigBee module or have one. The module 41 is in Fig. 14 shown schematically. The supply unit 11 can thus also be regarded as a communication unit of the lighting unit 4, with a flat design of the circuit board 37 and the components arranged thereon advantageously contributing to the flat and space-saving design of the supply unit 11.

In a longitudinal direction L "of the supply unit 11, which in the assembled state is parallel to the longitudinal direction L ', the board 37 is arranged centrally within the housing element 13. In the longitudinal direction L" is on both sides of the board 37, in each case in an end region of the housing element 13, a cuboid permanent magnet 42 is accommodated in the housing element 13, in other words, the supply unit 11 has two permanent magnets 42. Each permanent magnet 42 is held by latching devices 43, in the example shown in the form of bevelled lugs which engage behind the permanent magnet 42.

The housing element 13 has on one side, which in the inserted state of the lighting unit 4 in the channel 3 faces the base of the channel 3 and thus the busbar 10, a ceiling section 44 and wall sections projecting essentially vertically from the ceiling section 44 on all four edges thereof 45a-d. The wall sections 45a and 45c on the long sides of the housing element 13 are in each case elongated in their direction of extension normal to the ceiling section 44 by protrusions 46 spaced apart from one another. Each of the projections 46 carries a latching hook 47 at its free end. The projections 46 with the latching hooks 47 form the latching devices 14. In Fig. 14 For the sake of clarity, this is only shown for some locking devices 14.

The ceiling section 44 is equipped with two cross-shaped openings 48, a permanent magnet 42 being visible through the openings 48, see 12 and 13 , Furthermore, the ceiling section 44 has through openings 38 through which the contact devices 36 'pass through the housing element 13.

The supply unit 11 is, see for example Fig. 9 , snapped onto the housing component 21 from a rear side of the light supply and optical unit 12 facing away from the light exit region 15. The plurality of latching hooks 47 engage behind the longitudinal ribs 27, as a result of which the supply unit 11 and the light supply and optical unit 12 are securely coupled to one another.

The supply unit 11 is not only used for the electrical supply of the light supply and optics unit 12, but is also designed as a holding unit for the lighting unit 4 in order to hold the lighting unit 4 in the channel 3. After insertion into the channel 3, the lighting unit 4 is magnetically coupled to the channel 3 by means of the permanent magnets 42 and reliably held in the channel 3. For this purpose, the sections 2 of the channel 3 have sections 49 of a steel core 50, the steel core 50 interacting as a ferromagnetic element with the permanent magnets 42 for fastening the lighting units 4. The steel core 50, like the busbar 10, forms part of the channel 3. The sections 49 are held within the profile body 7 with the aid of the base body 19, see in particular 2 and 3 ,

The wireless control of the lighting unit 4 via the module 41 avoids the space requirements associated with a wired control. Additional contact elements for tapping the control signals and corresponding space on the board are not necessary. In this way it becomes possible to keep the supply unit 11 particularly narrow and slim. In addition, it is also possible to make the connector 5 very flat, especially since no control lines, but only the two conductors 20 are to be electrically coupled across the joint 6.

The housing element 13 is preferably injection molded. The housing element 13 is preferably designed as a plastic injection molded part.

Fig. 29 shows the connector 5 separately. The connector 5 has a substantially cuboid connector housing 51 formed with two parts. The connector housing 51 is formed with a connector housing part 51a and a connector housing part 51b, wherein the connector housing parts 51a, 51b are each formed with a plastic material. The connector housing parts 51a, 51b can also be injection molded, for example.

Movable snaps 52a, 52b are arranged on the longitudinal sides thereof near the four corners of the cuboid connector 5. Of these are in Fig. 29 only two are shown, but it goes without saying that the further two catches 52 are symmetrical to the longitudinal direction L "'of the connector 5 on the in FIG Fig. 29 hidden longitudinal side of the same are provided, in particular the second catch 52a is symmetrical to that in FIG Fig. 29 visible catch 52a and the second catch 52b symmetrical to that in FIG Fig. 29 visible snap 52b arranged.

The connector 5 also has an actuating element 54a, 54b at opposite ends 53, of which in FIG Fig. 29 only one is also visible in Fig. 5 however both are shown on.

For actuation, the actuation elements 54a and 54b can be pressed in, as a result of which the catches 52a, 52b projecting from the connector housing 51 without actuation of the actuation elements 54 can be inserted into the connector housing 51. For example, the actuating element 54a can act on the two catches 52a at one end 53 of the connector housing 51 and the actuation element 54b on the catch 52b at the other end 53 of the connector housing 51. A suitable mechanism may be provided inside the connector housing 51.

The catches 52a, 52b here form latching devices which make it possible to mechanically couple the connector 5 in a space-saving manner in a latching and releasable manner to two adjoining sections 2 of the channel 3 at the joint 6. The catches 52a and 52b engage behind the longitudinal ribs 55 in the inner region 9 of the channel 3 (see Fig. 3 ), wherein the longitudinal ribs 55 are formed in the side walls 18 of the profile body 7 and are shaped so as to be chamfered toward the opening 35 ' are. In this way, the connector 5 is held on the sections 2 of the channel 3 and, in addition to the electrical coupling of the busbar sections 8, can give the sections 2 a slight mechanical guidance in the region of the joint 6 and facilitate the alignment of the sections 2 to one another.

By actuating the actuating elements 54a, b, the catches 52a, b can be pulled back into the connector housing 51, whereby the catches 52a, b out of engagement with the longitudinal ribs 55, see Fig. 3 , arrive and the connector 5 can be removed again.

In order to establish the electrical coupling of the busbar sections 8 which meet in the joint 6, the connector 5 has two pairs of contact elements 56a and 56b, see Fig. 29 , When the connector 5 is inserted into the channel 3, the contact elements 56a, b come into contact with the conductors 20 on both sides of the joint 6, such that the contact elements 56a sections of one of the conductors 20 and the contact elements 56b sections of the other of the conductors 20 via the joint 6 connect. For this purpose, the contact elements 56a on the one hand and the contact elements 56b on the other hand are electrically connected to one another in the connector housing 51.

Fig. 3 illustrates for the first embodiment a depth direction T of the channel 3 and a transverse direction Q of the channel 3 normal and thus transverse to the depth direction T.

In Fig. 9 are - for the state of the lighting unit 4 inserted in the channel 3 - an extension of the lighting unit 4 parallel to the depth direction T with T4, an extension of the light supply and optics unit 12 parallel to the depth direction T with T12 and an extension of the lens 26 parallel to the depth direction T. designated T26. Contact elements 33 and contact devices 36 'are not taken into account for the measurement of T12 and T4, see Fig. 9 ,

Along the transverse direction Q, the width direction B in the inserted state of the lighting unit 4 (see Fig. 3 ) The lens 26, the light supply and optics unit 12 and the supply unit 11 each run in parallel are shown in FIG Fig. 9 the extension the light supply and optics unit 12 with B12 and the extension of the lens 26 with B26. For the lens 26 of the Fig. 3 and 9 is B26> T26.

Fig. 10 also shows, for the state of the lighting unit 4 inserted in the channel 3, an extension B13 of the housing element 13 in the transverse direction Q and thus along a width direction of the housing element 13, and an overall extension T13 of the housing element 13 parallel to the depth direction T and an extension T45 of the same to the depth direction T without the projections 46. The contact devices 36 'are also disregarded for the measurement of T13 and T45.

Fig. 3 also shows the outer dimensions in cross section of the channel 3, in other words the height T2 of the channel 3 and the sections 2 parallel to the depth direction T and the width B2 of the channel 3 and the sections 2 in the transverse direction Q and thus normal to the depth direction T.

In the first exemplary embodiment, B2 = 31.0 mm and T2 = 31.0 mm, for example.

B13> 0.9 B12 applies to the lighting unit 4 of the first exemplary embodiment. Thus, the width extension of the housing element 13, and thus also the supply unit 11, in the transverse direction Q normal to the depth direction T is greater than 90 percent of the width extension B12 of the light supply and optics unit 12 in this direction. In the first exemplary embodiment, B12 = 27.2 mm, B13 = 25.7 mm applies by way of example and preferred.

Furthermore, T12 = 14.1 mm and T4 = 20.5 mm apply, for example and preferably, to the lighting unit 4 of the first exemplary embodiment. Thus, in the first exemplary embodiment T4 <B12, B12 also indicating the maximum extent of the lighting unit 4 in the width direction B, that is to say in the transverse direction Q.

In addition, by way of example and in the case of the supply unit 11 according to the first exemplary embodiment, T13 = 9.5 mm and T45 = 6.2 mm.

A thickness D51 of the connector housing 51, see Fig. 29 , which denotes an extension of the connector housing 51 in the thickness direction D of the connector 5 and does not take the contact elements 56a, b into account, corresponds by way of example and preferably to approximately 6 mm. The thickness direction D is essentially parallel to the depth direction T of the channel 3 when the connector 5 is inserted into the channel 3. In particular, the thickness D51 roughly corresponds to a dimension, here by way of example and preferably T4-T12 = 6.4 mm, by which the housing element 13 in the lighting unit 4, see Fig. 9 , in the state of the lighting unit 4 inserted into the channel 3, protrudes parallel to the depth direction T via the light supply and optics unit 12 and in particular via its housing component 21. The thickness D51 is preferably not greater than the projection T4-T12.

A depth T9 'of channel 3 available for receiving the lighting unit 4, see Fig. 3 , is by way of example and preferably about 20.5 mm. Thus, the lighting unit 4 received in the channel 3 is essentially flush with the edges 34 '. Furthermore, an inner width W2 of the channel 3, see Fig. 3 , in the area of the opening 35 'by way of example and preferably approximately 28 mm.

Fig. 3 furthermore shows that the width B13 of the housing element 13 is essentially selected such that the supply unit 11 can be inserted without problems between the side walls 18, the distance of which at the location of the supply unit 11 in its inserted state is reduced in the transverse direction Q with respect to the width W2 , The width B51 of the connector housing 51, see Fig. 29 , in the transverse direction Q in the inserted state of the connector 5 can essentially correspond to the width B13.

Fig. 15 shows a lighting system 1 according to a second embodiment. The differences from the first exemplary embodiment are explained below. For further features, in particular with regard to the channel 3 and its sections 2 and in particular also with regard to the busbar 10 and its busbar sections 8, reference is made to the above explanations regarding the first exemplary embodiment.

In Fig. 15 two sections 2 of the channel 3 of different lengths L2a, L2b are shown for illustration. Furthermore shows Fig. 15 two light units 104a, 104b with different lengths L104a> L104b. Each of the lighting units 104a, 104b has a light supply and optical unit 112a or 112b. In addition, the longer lighting unit 104a has two, for example, identical supply units 11, while the shorter lighting unit 104b is only provided with one supply unit 11.

Furthermore, a section 136 of the light supply and optics unit 112a completely overlaps with the connector 3, see Fig. 15 , The connector 5 is essentially completely covered by the section 136, but the two lighting units 104a and 104b limit the arrangement of the Fig. 15 not directly in front of each other in front of the connector 5, but outside the area in which the connector 5 is located in the channel 3. The portion 136 overlapping with the connector 5 is thus not an end portion but an inner portion of the light providing and optical unit 112a.

It is also conceivable that a section 136 of a light supply and optical unit 112a, which is located between two supply units 11, overlaps with the connector 5 if the supply units 11 are sufficiently spaced from one another.

Alternative profile body 7 ', 7 ", 7"' with the respective inner region 9 ', 9 ", 9"', which instead of the profile body 7 Fig. 3 can be used for the channel 3 according to the second, or also according to the first embodiment for alternative mounting situations Figures 15A, 15C and 15B ,

In Fig. 15 Also shown is a current feed unit 57 for feeding electrical current into the busbar 10 of the channel 3. As in Fig. 15 can be seen, the power supply unit 57 can be used similar to the connector 5 in the channel 3 such that it with the lighting unit 4 and in particular a portion of the light supply and optics unit, z. B. 112a, overlapped and completely covered by this section, for example.

Fig. 30 shows the flat, in the channel 3 snap-in power supply unit 57 together with a piece of line 58. The power supply unit 57 has a substantially cuboid power supply unit housing 61, which is formed with two housing parts 61 a, 61 b. The housing parts 61a, 61b are each formed with a plastic material and, for example, also injection molded.

The flexible, current-carrying line 58 enters the housing 61 at a first end 62a of the current feed unit 57, while the current feed unit 57 enters it at the opposite end 62b (in Fig. 30 Has not visible) actuating element 63, which is formed analogously to the actuating element 54a or 54b of the connector 5.

Adjacent to the end 62a, the current feed unit 57 has latches 59 arranged symmetrically to its longitudinal direction on the long sides, while the current feed unit 57 has two movable catches 60 on the long sides adjacent to the end 62b. The catches 60 are also arranged symmetrically to the longitudinal direction of the current feed unit 57. The locking lugs 59 can be behind each of the longitudinal ribs 55 ( Fig. 3 ) engage elastically. The catches 60 are analogous to the catches 52a, 52b of the Fig. 29 also set up to engage behind the longitudinal ribs 55. The locking lugs 59 and the catches 60 thus form locking devices which make it possible to mechanically couple the power feed unit 57 to the channel 3 in a detachable and releasable manner.

For actuation, the actuating element 63 can be pressed in, as a result of which the catches 60 which protrude from the current feed unit housing 61 without actuation thereof are withdrawn, analogously to the mode of action of the catches 52a, 52b of the connector 5. After actuation of the actuation element 63, the coupling of the current feed unit 57 can be release with channel 3.

Electrical coupling of the busbar 10 to the power supply unit 57 is achieved via contact elements 64a, 64b, which are each electrically connected to a conductor of the line 58. When the current feed unit 57 is inserted into the channel 3, the contact element 64a arrives with one of the conductors 20 (see Fig. 3 ) and the contact element 64b in contact with the other of the conductors 20.

A thickness 61 of the current feed unit housing 61 in a thickness direction, which is essentially parallel to the depth direction T when the current feed unit 57 is in use, can correspond approximately to the thickness D51 of the connector housing 51, for example. Furthermore, a width B61 of the power supply unit housing 61 in a width direction which, in the inserted state of the power supply unit 57, is normal to the depth direction T, may correspond approximately to the width B51 of the connector housing 51, for example.

Fig. 16 shows how the line 58 in the assembled lighting system between the busbar 10 and the light supply and optics unit 112a can be led out from the end of the channel 3, for example, in order to connect the line 58 to a power source, for example a converter.

One in Fig. 15 Light unit 104, not shown, for the lighting system according to the second exemplary embodiment is shown in FIGS Fig. 17-20 shown in more detail, with the following explanations Fig. 17-20 analogously for the lighting units 104a, 104b Fig. 15 be valid.

The lighting unit 104 has a supply unit 11 and a light supply and optics unit 112. The supply unit 11 of the Fig. 17-20 is formed in the same way as in the first embodiment. The differences between the light providing and optical unit 112 in comparison with the light providing and optical unit 12 are explained below.

The light supply and optics unit 112 has a housing component 121 which is open to the visible side S and the light exit region 15. A linearly elongated lens 126 is accommodated in an interior 122 of the housing component 121 and is held in the housing component 121, for example by latching edge regions 129 of the lens 126 into flat recesses 130. A front face 126a of the lens 126 through which light is emitted is substantially flat.

An LED circuit board 124 with LEDs 125 is accommodated in the housing component 121. The lens 126 has a recess 128 which lies opposite the LEDs 125. The cross section of the lens 126 is substantially constant along a longitudinal direction thereof. An extension of the lens 126, in the inserted state of the lighting unit 104 into the channel 3, parallel to the depth direction T is also less for the lens 126 than an extension of the lens 126 in the transverse direction Q normal to the depth direction T. The lens 126 is designed for one to generate symmetrical light distribution.

For locking the supply unit 11 with the light supply and optics unit 112 analogously to the first exemplary embodiment, the housing component 121 has lateral longitudinal ribs 127, behind which the locking devices 14 can snap in when the lighting unit 104 is assembled.

As an example and preferably, the extension T104 of the lighting unit 104 can be parallel to the depth direction T in Fig. 19 T104 = 20.5 mm. An extension T112 of the light preparation and optics unit 112 parallel to the depth direction T can be seen in FIG Fig. 19 furthermore, by way of example and preferably T112 = 14.3 mm. The extension B112 of the light preparation and optics unit 112 in the width direction B, which in the inserted state of the lighting unit 104 runs parallel to the transverse direction Q, is in FIG Fig. 19 exemplary and preferred B112 = 25.4 mm. B13> 0.9 B112 applies to the lighting unit 104, in particular B13> B112. Further, in the second embodiment, T104 <B112 and T104 <B13. The projection of T104-T112 = 6.2 mm of the supply unit 11 over the light supply and optical unit 112 essentially corresponds to the thickness D51 of the connector housing 51 or is slightly larger than D51.

A lighting unit 204 according to a third exemplary embodiment illustrates the Fig. 21-24 , The differences in comparison with the lighting unit 104 are to be described below.

The lighting unit 204 has a supply unit 11 and a light supply and optical unit 212, with a housing component 221 of the light supply and optical unit 212 essentially the housing component 121 the Fig. 19 is designed accordingly and has an interior space 222, an opening 223 to the supply unit 11, lateral longitudinal ribs 227 for locking with the locking devices 14 of the supply unit 11, and cutouts 230.

A linearly elongated lens 226 is received in the interior 222, the cross section of which is essentially constant along a longitudinal direction of the lens 226. A front side 226a of the lens 226, through which light is emitted, is also essentially flat, except for peripheral areas. Edge regions 229 of the lens 226 are snapped into the cutouts 230 of the housing component 221.

Furthermore, an LED circuit board 224 with LEDs 225 is accommodated in the interior 222. Facing the LED board 224, the lens 226 has a recess 228 in which the LEDs 225 are arranged and shine into it.

Also in the case of the lens 226, its extension, in the inserted state of the lighting unit 204 into the channel 3, parallel to the depth direction T is less than the extension of the lens 226 in the transverse direction Q normal to the depth direction T. The lens 226 is preferably designed for the emitted light focus more.

As an example and preferred, the extension T204 of the lighting unit 204 can be parallel to the depth direction T in Fig. 23 T204 = 20.3 mm. An extension T212 of the light providing and optics unit 212 parallel to the depth direction T can be seen in FIG Fig. 23 furthermore by way of example and preferably T212 = 14.1 mm. The extension B212 of the light supply and optics unit 212 in the width direction B, which in turn runs parallel to the transverse direction Q when the lighting unit 204 is in use Fig. 23 exemplary and preferred B212 = 25.4 mm. B13> 0.9 B212 applies to the lighting unit 204, in particular B13> B212. Further, in the third embodiment, T204 <B212 and T204 <B13. The overhang of T204 - T212 = 6.2 mm of the supply unit 11 over the light supply and optical unit 212 also corresponds essentially to the thickness D51 of the connector housing 51 in this exemplary embodiment or is slightly larger than D51.

A lighting unit 304 according to a fourth exemplary embodiment illustrates the 25 and 26 , With regard in particular to the supply unit 11 of the lighting unit 304, reference is again made to the above statements. In the following, the differences of the lighting unit 304 in comparison with the above exemplary embodiments are to be described.

The lighting unit 304 has a light supply and optics unit 312, which has a housing element 321 with an interior 322. An LED circuit board 324 with LEDs 325 and a lens 326 are received in the interior 322. The lens 326 is linearly elongated with a substantially constant cross section along its longitudinal direction and is designed to generate an asymmetrical light distribution.

A front side 326a of the lens 326, through which light is emitted, is also essentially flat, except for peripheral areas. Edge regions 329 of the lens 326 are snapped into recesses 330 in the housing component 321, see Fig. 26 , In this case, the lens 326 in the region of the front side 326a does not extend over the entire width of the housing component 321, but an opening of the housing component 321, in the region of whose edges the recesses 330 are arranged, is narrower than by a wall section 321a which is essentially parallel to the front side 326a in the examples of Fig. 19 or 23 executed.

The lens 326 has a recess 328 facing the LED circuit board 324, in which the LEDs 325 are arranged and shine into it. In the case of the lens 326, too, its extension, in the inserted state of the lighting unit 304 into the channel 3, parallel to the depth direction T is less than the extension of the lens 326 in the transverse direction Q normal to the depth direction T.

As an example and preferred, the extension T304 of the lighting unit 304 can be parallel to the depth direction T in Fig. 26 T304 = 25.2 mm. An extension T312 of the light preparation and optics unit 312 parallel to the depth direction T can be seen in FIG Fig. 26 furthermore by way of example and preferably T312 = 19 mm. The extension of the light supply and optics unit 312 in the width direction B, which in turn runs parallel to the transverse direction Q when the lighting unit 304 is in the position. is in Fig. 26 exemplary and preferred B312 = 25.4 mm. B13> 0.9 B312 applies to the lighting unit 304, in particular B13> B312. Further, in the fourth embodiment, T304 <B312 and T304 <B13. However, T304 and B312 are almost the same size in the fourth embodiment. In particular, when the lighting unit 304 is inserted into the channel 3, the Fig. 3 the lighting unit 304 emerges from the opening 35 'of the channel 3 over the edges 34'. The protrusion of T304-T312 = 6.2 mm of the supply unit 11 over the light supply and optics unit 312 also corresponds essentially to the thickness D51 of the connector housing 51 in this exemplary embodiment or is slightly larger than D51.

A fifth embodiment is shown in Fig. 27 illustrated, wherein a lighting unit 404 protrudes from the opening 35 'of the channel 3 over the edges 34' from the inner region 9. Nevertheless, the lighting unit 404 overlaps with the connector 5 (in Fig. 27 not shown) within the channel 3.

In the sixth embodiment of the Fig. 28 A lighting unit 504 is provided, which is dimensioned relative to the channel 3 such that the lighting unit 504 is set back in relation to the edges 34 'in the inserted state. The lighting unit 504 is thus completely accommodated in the inner region 9 of the channel 3, but is not flush with the edges 34 'of the opening 35'.

A lighting unit 604 according to a seventh exemplary embodiment illustrates the 31 and 32 , Like the lighting unit 304, the lighting unit 604 also serves to generate an asymmetrical light distribution. In the following, the differences between the lighting unit 604 and the lighting unit 304 are to be described, whereby reference is also made to the above explanations.

A housing element 621 of a light supply and optics unit 612 of the lighting unit 604 accommodates in its interior 622, in addition to an LED circuit board 624 with LEDs 625, a linearly elongated lens 626 which, however, unlike the lens 326 described above, is located on the visible side S. over substantially the entire width of the housing element 621, see Fig. 32 , extends. In Fig. 32 extends through the substantially plane front side 626a of the lens 626 the light is emitted, thus over a large part of the width of the housing element 621. Edge regions 629 of the lens 626 are snapped into recesses 630 of the housing component 621.

The lens 626 also has a recess 628 facing the LED circuit board 624, in which the LEDs 625 are arranged. Also in the case of the lens 626, the extension of the lens 626, in the inserted state of the lighting unit 604 into the channel 3, parallel to the depth direction T is less than the extension of the lens 626 in the transverse direction Q normal to the depth direction T.

As an example and preferably, the extension T604 of the lighting unit 604 can be parallel to the depth direction T in Fig. 32 T604 = 20.3 mm. An extension T612 of the light providing and optics unit 612 parallel to the depth direction T can be seen in FIG Fig. 32 furthermore by way of example and preferably T612 = 14.1 mm. The extent of the light supply and optics unit 612 in the width direction B, which in the inserted state of the lighting unit 604 again runs parallel to the transverse direction Q, is in FIG Fig. 32 exemplary and preferred B612 = 25.4 mm. B13> 0.9 B612 applies to the lighting unit 604, in particular B13> B612. Further, in the seventh embodiment, T604 <B612 and T604 <B13. In particular, when the lighting unit 604 is inserted into the channel 3, the Fig. 3 the lighting unit 604 is substantially flush with the edges 34 '. The protrusion of T604-T612 = 6.2 mm of the supply unit 11 over the light preparation and optics unit 612 also corresponds essentially to the thickness D51 of the connector housing 51 in this exemplary embodiment or is slightly larger than D51.

The Fig. 33-36 show a lighting system 1 according to an eighth exemplary embodiment, the differences from the second exemplary embodiment being explained below. In addition, reference is made to the comments on the second embodiment.

In the assembled lighting system 1 according to the eighth exemplary embodiment, the line 58 is led out of the channel 3 through a passage 765 in the section 2 of the channel 3 in order to connect the line 58 to a current source, for example a converter. Passage 765 is in Fig. 33 and 34 as a through hole in section 2 of the channel 3, near an end face of section 2, executed. For this purpose, the passage 765 is made as a bore in the profile body 7. In order to allow access to the passage 765, the busbar section 8 can be made somewhat shorter than the section 2 of the channel 3 such that the busbar section 8 does not cover the passage 765.

Longitudinal front ends of the channel 3 are in Fig. 33 each with one, in the example the Fig. 33 substantially rectangular, end cover 766 closed, creating a closed lighting system.

For the lighting system 1 according to the eighth exemplary embodiment, for example, in Fig. 33 two lighting units 704a, 704b shown. The lighting unit 704a is designed such that it sits essentially flush in the opening 35 'of the channel 3, while the lighting unit 704b protrudes from the opening 35', see Fig. 36 ,

In addition, show in particular Fig. 33 and 35 how end faces 735 of the light units 704a-b can be closed off with an end cap 767 in the region in the longitudinal direction of the front ends of the light supply and optical unit 712a or 712b. In the case of a butt joint 6 directly above the connector 5, end caps 767 may be omitted at this point or the height may be suitably adjusted.

Some profile bodies 7 "", 7 "', 7" that can be used for the sections 2 of the channel 3 in the lighting system 1 according to the eighth exemplary embodiment are shown by way of example Figure 33A in the sub-images (a), (b) and (c).

In the case of the lighting units 104, 204, 304 and 604 in particular, the housing components 121, 221, 321 and 621 are not necessarily translucent in each case, but can be opaque. A translucent or opaque housing component is also conceivable for the lighting units 404, 504 and 704a, b.

It should be mentioned that the lighting units 4, 104, 104a-b, 204, 304, 404, 504, 604, 704a-b described above with reference to the exemplary embodiments combine, for example, in one of the channels 3 described above, and in addition depending on the lengths and channel length selected lengths can be used. This creates a wide range of possible combinations. In addition, the lighting units 4, 104, 104a-b, 204, 304, 404, 504, 604, 704a-b can each be used in channels 3 with different profile bodies 7, 7 ', 7 ", 7"', 7 "".

The wireless switching and / or control of the light output by the lighting units 4, 104, 104a-b, 204, 304, 404, 504, 604, 704a-b, which is provided in all of the exemplary embodiments described above, makes the lighting system easy to operate and particularly space-saving , slim construction achieved.

The lenses 26, 126, 226, 326, 626 described above in relation to the exemplary embodiments enable a flat appearance, in particular in the depth direction T, and thus also contribute to a reduction in the space requirement and in particular the installation depth of the channel 3. Especially in combination with a flat-shaped supply unit 11 and a wireless control of the lighting units, the slim magnetic fastening solution for the lighting units, and the flat connector 5, space and installation depth are advantageously saved and yet very aesthetic lighting solutions are made possible.

Since the supply unit 11 has the same structure in all of the exemplary embodiments explained above, the structure of the lighting system can be simplified and costs can be saved by standardizing components. For different lighting units 4, 104, 104a-b, 204, 304, 404, 504, 604, 704, however, if necessary or desirable, the circuit board 37 can each be designed and / or equipped in a manner adapted to the lighting unit, or instead always identical be trained.

The magnetic fastening solution by means of the permanent magnets 42 and the steel core 50 enables in all of the exemplary embodiments explained above simple, quick and reliable fastening of the light units 4 to 704 and small sizes.

In all of the above-described exemplary embodiments, for example, lighting units with lengths L4 of approximately L4 = 300 mm or approximately L4 = 600 mm or L4 = 1200 mm or L4 = 1800 mm or L4 = 2400 mm can be provided, with light strips being 4 different by combining lighting units and / or the same lengths and a corresponding number of connectors 5 can be built. While short lighting units 4 can make do with one supply unit 11, longer lighting units 4 are preferably provided with two or more supply units 11. For the lengths L104, L204, L304, L604 of the light units 104, 204, 304 and 604 as well as for the lengths of the light units 404, 504, 704a-b the above explanations for L4 apply accordingly. Lengths other than those mentioned above are also conceivable, for example approximately L604 = 500 mm.

If a light strip with a given, desired total length is not solely by combining lighting units 4-704 from several of the lengths provided, e.g. B. L4, L104, L204, L304, L604, can be created by combination, it is possible to better adapt the lighting units by shortening the light supply and optical unit in the case of each of the above-described embodiments to the desired length. For this purpose, the LED circuit board 24 can be severed at regular intervals.

For the above exemplary embodiments, the connector 5 is designed as a linear connector for coupling busbar sections 8, which are associated with straight sections 2 of the channel 3 arranged in succession in a straight line. However, in a variant not shown in the figures, the connector 5 can be designed to electrically couple busbar sections 8 which belong to straight-line sections 2 which follow one another in an angled manner.

In the lighting systems according to all of the exemplary embodiments described above, it can be provided that the channel 3 extends over shorter or longer periods Partial areas along its longitudinal direction are not equipped with the lighting units 4, 104, 104a-b, 204, 304, 404, 504, 604 and / or 704a-b described above, but that one or more additional lighting inserts of other types are used in the channel 3 is / are. Parts of channel 3 can also remain empty. The additional lighting inserts are preferably lighting inserts which supply electricity via the busbar 10 in a manner analogous to the lighting units 4, 104, 104a-b, 204, 304, 404, 504, 604 and / or 704a-b described above and their light output can be switched and / or controlled wirelessly, for example via ZigBee. However, it can be provided that one or more of the additional lighting inserts are not set up to overlap with the connector 5. The additional luminaire inserts can each be designed, for example, as a spot, as a pivotable spot, as a suspended spot, as a wall washer, as a linear arrangement of spots, as a linear diffuse-emitting luminaire insert or as a pendant luminaire.

Although the present invention has been fully explained above on the basis of preferred exemplary embodiments, it is not restricted thereto, but can be modified in a variety of ways.

For example, the lighting unit could be set up in addition to the magnetic attachment for a supplementary, form-fitting snap or snap connection with the channel.
