Description

Technical Field

[0001] The invention relates to a track for a track lighting system and configured as a profile. The invention also relates to a lighting device comprising a track of this type and comprising an adapter inserted into an inner area of ​​the track and at least one module electrically coupled to the adapter. Background Art

[0002] Track lighting systems, for example for lighting in buildings, are known per se.

[0003] For example, DE102021202972A1 describes a lighting device based on a modular track lighting system, wherein the track profile described has an open visible side, comprising a first inner area and a second inner area located above the first inner area. In DE102021202972A1, a conductor unit for providing electrical energy and control signals is provided in the second inner area, which has, for example, six or ten conductors in total. The second inner area is configured to accommodate an adapter unit including a converter. The adapter unit can be coupled to the conductor unit to receive electrical energy and / or control signals. The lighting module can be inserted into the first inner area from below and powered by the adapter unit.

[0004] DE 10 202 204 266 A1 also describes a track for a track lighting system. DE 10 202 204 265 A1 further describes an adapter for a track lighting system.

[0005] It is now desired that the track of a track lighting system not only provide operating current and control signals to the lighting units serving the main lighting purpose of the track lighting system, but also provide a path for current and / or signals to achieve one or more special or additional functions, while allowing a high degree of flexibility in the use of adapter units. Summary of the invention

[0006] Against this background, the object of the present invention is to provide an option for equipping a track lighting system with a main function on the one hand and with one or more additional functions on the other hand, while achieving a flexible and simple usability of the adapter.

[0007] According to the invention, this object is achieved by a rail comprising the features of claim 1 and / or by a lighting device comprising the features of claim 17 .

[0008] Therefore, a track for a track lighting system is proposed, which is configured as a profile and has an inner area. In the inner area, a conductor unit is provided with conductors extending substantially in the longitudinal extension direction of the track, at least for providing current and control signals. The inner area is configured to at least optionally accommodate a first adapter for contacting conductors from a first group of conductors, and a second adapter for contacting conductors from at least one second group of conductors and / or a third group of conductors. The conductors of the first group include conductors for providing an operating current for a lighting module and conductors for providing the control signal. The second group and the third group are intended to provide at least one additional function. According to the present invention, the conductors of the first group are arranged between the conductors of the second group and the conductors of the third group in the depth direction of the inner area, and the first adapter or the second adapter can be inserted into the inner area starting from the outwardly opening side of the inner area along the depth direction.

[0009] Furthermore, the lighting device comprises a track according to the present invention, at least one adapter inserted into the inner area of ​​the track, and at least one module electrically coupled to the adapter.

[0010] The module electrically coupled to the adapter is configured as a lighting module, the adapter contacts the conductors of the first group of conductors of the conductor unit provided in the inner region of the track and thereby taps the operating current and control signals for the lighting module from the conductors of the first group; or,

[0011] A module electrically coupled to the adapter is used to provide at least one additional function of the lighting device, the adapter contacts a conductor in the second group or the third group of conductors of the conductor unit arranged in the inner area of ​​the track, and thereby taps an operating current and / or taps or feeds a signal for the additional function.

[0012] A basic idea of ​​the invention is to ensure that, by the arrangement of the first, second and third groups, a first adapter is not only compatible with the track according to the invention, but also works with simpler tracks with a smaller number of conductors limited to the first group, the first adapter providing selective contact with the conductors present in total (i.e. the conductors of the first group) and making it possible to tap the operating currents of the lighting modules, for example control signals from these modules. Furthermore, this makes it possible to use the track according to the invention with a first adapter configured to be used only with conductor units corresponding to the first group, these adapters being standard adapters.

[0013] However, advantageously, not only can the first adapter be in functional contact with the track according to the invention, but the track can also be used with a second adapter capable of contacting the second and / or third set of conductors. Thus, in addition to the main lighting function provided by the first set, the second adapter can also provide an additional or dedicated function, which can be provided with power and / or signals by the second or third set or both, and / or its signals can be forwarded by the second or third set or both.

[0014] It is worth understanding that the first adapter and the second adapter can be used for different sections of the same track, each section possibly several times. This makes possible a highly flexible and very functional lighting layout.

[0015] With regard to the first and second adapters, the arrangement of the first, second and third groups can also advantageously, in particular, enable the first adapter or the second adapter configured for use with the track according to the invention to have, at least in cross section, substantially the same or similar geometrical outer dimensions as a standard adapter corresponding only to the conductor of the first group. This is advantageously achieved by arranging the second and third groups in the depth direction, so that neither the second nor the third group takes up too much additional space.

[0016] Advantageous embodiments and developments of the invention are apparent from the dependent claims and from the description with reference to the drawings.

[0017] In one embodiment, the conductors of the first group are configured to provide the operating current for the lighting module, and are configured to provide the operating current at a mains voltage, specifically alternating current, for example at a nominal voltage of substantially 230V.

[0018] In one refinement, the first group can provide a multi-phase alternating current for operating the lighting module. For example, this may enable a phase to be selected from these phases that can be used by the first adapter.

[0019] In one embodiment, the second group of conductors comprises conductors for providing an operating current or signal for at least one additional function of the track lighting system, and / or the third group of conductors comprises conductors for providing an operating current or signal for at least one additional function of the track lighting system.

[0020] In one refinement, in a cross section of the track, the conductors of the conductor unit are arranged symmetrically about the longitudinal center plane of the inner region. This can contribute to a relatively simple track construction, in particular the conductor unit, which is also beneficial to the manufacture of the track.

[0021] In one embodiment, in a cross section of the track, the positions of the conductors of the conductor unit are also arranged symmetrically about a symmetry plane, which extends transversely, in particular perpendicularly, to the longitudinal center plane of the inner area and transversely, in particular perpendicularly, to the depth direction. Therefore, the space required for the conductors, in particular the second group and the third group, is more evenly distributed in the depth direction.

[0022] In a further embodiment, the conductors of the conductor unit are arranged on both sides along the longitudinal sides of the inner area, in particular the same number of conductors are arranged along each longitudinal side. This enables a space-saving, compact conductor arrangement and thus a compact track and an overall compact track lighting system.

[0023] In a refinement, the conductor unit has ten conductors, five of which are arranged along each longitudinal side of the inner area, the first group comprising six of the conductors, the second group and the third group each comprising two of the conductors. This makes it possible, for example, to provide a plurality of phases as a power supply for a main lighting function, as well as the associated control signals, and to provide a sufficient number of additional conductors for additional functions, which, however, are simultaneously limited in such a way that only a small space requirement results, which can be evenly distributed between the second and third groups in an advantageous manner.

[0024] In a further improvement, the first group comprises a neutral conductor, a first phase conductor, a second phase conductor, a third phase conductor, and two conductors for the control signal, in particular a DALI signal.

[0025] In one embodiment, the first group is formed into three subgroups, each subgroup includes two conductors of the first group, and along the depth direction, viewed from the outwardly open side of the inner region,

[0026] a first subgroup comprising said neutral conductor and said third phase conductor,

[0027] a second subgroup comprises said two conductors for said control signal, and

[0028] The third subgroup includes the first phase conductor and the second phase conductor.

[0029] This may further facilitate a substantially symmetrical construction of the track, for example in order to adapt the conductors to their intended functions within the first to third subgroups, as described above.

[0030] In a refinement, one of the second and third groups comprises the phase conductors and the neutral conductor of the first dedicated AC circuit; the other of the second and third groups comprises the phase conductors and the neutral conductor of the second dedicated AC circuit. Thus, two dedicated or additional functions, or for example two dedicated / additional functions of this type, can advantageously provide AC power separately.

[0031] In another embodiment, one of the second and third groups comprises a phase conductor and a neutral conductor of a first dedicated AC circuit; the other of the second and third groups comprises two conductors for providing a positive and negative pole of a dedicated DC circuit. In this way, dedicated or additional functions, or other variants, for example, can advantageously provide different types of current and / or supply from different energy sources, for example from an AC network on the one hand and from a battery on the other hand.

[0032] In another embodiment, one of the second group and the third group may include conductors for the positive and negative poles of the first dedicated DC circuit; the other of the second group and the third group may include conductors for the positive and negative poles of the second dedicated DC circuit.

[0033] In another embodiment, one of the second and third groups comprises a phase conductor and a neutral conductor of a first dedicated AC circuit, or two conductors for providing a positive and negative pole of a dedicated DC circuit; the other of the second and third groups comprises two conductors for providing or forwarding a signal. In addition to the power supply for the additional function, a signal for this or for a second additional function can also be provided, or a signal assigned to the additional function can be forwarded. The signal can be, for example, another control signal or an audio signal or a data signal. For example, an audio signal can be provided to a speaker module, or a data signal can be provided by a sensor module.

[0034] In a refinement, the two conductors are configured to provide a positive pole and a negative pole of the dedicated DC circuit or the first dedicated DC circuit and / or the second dedicated DC circuit for providing DC power at a DC voltage of substantially 24V.

[0035] In a further refinement, the phase conductors and the neutral conductor for the dedicated AC circuit or the first dedicated AC circuit and / or the second dedicated AC circuit are configured to provide AC power at a mains voltage, for example at a nominal voltage of substantially 230V.

[0036] In one embodiment, the inner area is subdivided into a first area open to the outside and an inner second area, the second area is accessible through the first area, the second area is used to accommodate an adapter, the conductor unit is arranged in the second area, and further, the first area is configured to accommodate one or more lighting modules, in particular flat and elongated lighting modules, in the first area, in particular, the lighting modules are accommodated to be substantially flush with the edge of the track. This helps to accommodate the conductor unit in a well-protected manner in the inner second area, so that the lighting module inserted into the first area can cover the one or more adapters accommodated in the second area. The track lighting system constructed in this way is not only versatile, but also compact and beautiful.

[0037] In one embodiment, each side wall of the track in the first area has an engagement geometry, in particular a groove-like or rib-like engagement geometry, for locking and fastening the lighting module. This allows simple and fast fastening of the lighting module and also allows simple position correction of longitudinal displacements.

[0038] In one embodiment of the lighting device, the adapter is configured as a first adapter and has at most three contact units on two opposite sides thereof for contacting the conductors of the first group. Therefore, the first adapter can be used when constructing the lighting device to achieve the main lighting function.

[0039] In another embodiment, the adapter is configured as a second adapter and has at least one contact unit on two opposite sides thereof for contacting the conductors of the second group or the third group, or has at least two contact units on two opposite sides thereof for selectively contacting the associated conductors of the second group or the third group. This type of second adapter can be used when implementing additional functions.

[0040] In one refinement, the second adapter also has at least one contact unit on its opposite sides for contacting the associated conductors of the first group. For example, this can enable the control signal provided by the conductors of the first group to also be used to provide additional functions.

[0041] In one embodiment of the lighting device, the module electrically coupled to the adapter and for providing the additional functionality is configured as an emergency lighting module, or an illuminable emergency information module, or an illuminable indication module, or a speaker module, or a sensor module.

[0042] In one embodiment, the adapter has a converter for converting the tapped operating current. This makes it possible to use the operating current provided by the conductor unit as alternating current at the mains voltage to operate modules for main functions or additional functions, in particular lighting modules, at low voltage.

[0043] The above embodiments and improvements can be combined with each other as needed within a reasonable range. Other possible embodiments, improvements and implementations of the present invention also include combinations not explicitly mentioned of the features of the present invention described above or below with respect to the exemplary embodiments. In particular, those skilled in the art will also add various aspects as improvements or supplements to each basic form of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0056] The accompanying drawings are intended to provide a further understanding of the embodiments of the present invention. They illustrate embodiments and are used to explain the principles and concepts of the present invention in conjunction with the description. Other embodiments and many of the advantages mentioned will be apparent by reference to the accompanying drawings. The elements in the accompanying drawings are not necessarily shown to scale relative to each other.

[0057] In the drawings, functionally equivalent and operationally equivalent elements, features and components have the same reference numerals unless stated otherwise. DETAILED DESCRIPTION

[0058] Figure 1-4 , 6-9 and 11 show a rail 1 configured as a profile according to an embodiment, which is part of a track lighting system. Fig.11 ), the rail 1 has a substantially constant cross section. The rail 1 comprises a profile base 2 formed of a metal material, specifically an aluminum material, whose side walls 2a are connected by webs 2b.

[0059] The inner region 3 of the track 1 is subdivided into a first region 4 open to the outside and an inner second region 5. The second region 5 is accessible through the first region 4. In the second region 5, a conductor unit 7 is provided, which has a first part 10 and a second part 20 arranged on both sides along the longitudinal sides 3a, 3b of the inner region 3. Each of the first part 10 and the second part 20 has a retaining body 16 or 26 formed of an electrically insulating material, in particular a plastic material, and an electrical conductor 11, 12, 13, 14, 15 or 21, 22, 23, 24, 25 retained by the retaining body 16, 26. For example, the conductors 11-15, 21-25 can be formed of copper. In the second region 5, the first adapter 30, 30', 30" and the second adapter 70a-d, 70 can be substantially completely accommodated.

[0060] The conductors 11-15, 21-25 extend in the inner second region 5 parallel to the longitudinal extension direction L of the track 1. In the embodiment shown in the figures, each part 10, 20 of the conductor unit 7 comprises five conductors 11-15 and 21-25, respectively, so that the conductor unit 7 has a total of ten conductors 11-15, 21-25. Five conductors 11-15 are arranged along the longitudinal side 3a of the inner region 3, and five conductors 21-25 are arranged along the opposite longitudinal side 3b of the inner region 3.

[0061] Figure 3 , 4 The depth direction T of the inner region 3 is shown, along which each adapter 30, 30', 30", 70a-d, 70 can be inserted into the inner region 3 starting from the outwardly open side 8 of the inner region 3. To this end, the adapter 30, 30', 30", 70a, 70b, 70c, 70d or 70 passes through the first region 4 in the depth direction T and transversely to the longitudinal extension direction L into the second region 5.

[0062] In the cross section of the track 1, the positions of the conductors 11-15 are arranged symmetrically with respect to the positions of the conductors 21-25 about the longitudinal center plane LM of the inner region 3. Furthermore, the positions of the conductors 11, 12, 21, 22 in the cross section of the track 1 are arranged symmetrically with respect to the positions of the conductors 15, 14, 25, 24 about a symmetry plane S extending perpendicularly to the longitudinal center plane LM of the inner region 3 and perpendicularly to the depth direction T and extending through the two conductors 13, 23; see example Figure 1 and Figure 3 .

[0063] The conductors 11-15, 21-25 are divided into a first group 27, a second group 28 and a third group 29; see Figure 4 The first group 27 is formed by the six conductors 12 , 13 , 14 and 22 , 23 , 24 . The second group 28 is formed by the two conductors 11 and 21 , and the third group 29 is formed by the two conductors 15 and 25 .

[0064] From the depth direction T ( Figure 4 ), the conductors 12-14, 22-24 of the first group 27 are arranged between the conductors 11, 21 of the second group 28 and the conductors 15, 25 of the third group 29. In the assembled state of the track 1, the depth direction T can specifically be substantially vertically aligned, and in this assembled state the second group 28 is arranged above the first group 27 and the third group 29 is arranged below the first group 27.

[0065] Conductors 12, 14, 22, 24 are configured to provide operating current to lighting modules 40, 50, 60, as explained in more detail below, and conductors 13, 23 are configured to provide control signals. The control signals may be interpreted by adapter 30, 30', 30" or lighting modules 40, 50, 60.

[0066] The first group 27 is subdivided into three subgroups 27a, 27b and 27c, each of which is formed by two electrical conductors 12-14, 22-24 of the first group 27. Starting from the outwardly open side 8, along the depth direction T, the third group 29 is followed by the first subgroup 27a, then the second or central subgroup 27b, then the third subgroup 27c and finally the second group 28.

[0067] The conductors 12, 14, 22, 24 of the first and third subgroups 27a, 27c are configured to provide operating current for the lighting modules 40, 50, 60 at the mains voltage, specifically as an alternating current with a nominal voltage of 230 V and a frequency of 50 Hz. In the track 1 shown in the figures, the first phase L1 is applied to the conductor 12, the second phase L2 is applied to the conductor 22, the third phase L3 is applied to the conductor 24, and zero is applied to the conductor 14. Thus, the first group 27 provides the phases L1, L2, L3 of the mains alternating current for operating the lighting modules 40, 50, 60. The profile base 2 may provide a ground contact.

[0068] The first subgroup 27a is formed by conductors 14 and 24, with conductor 14 serving as a neutral conductor and conductor 24 serving as a third phase conductor. The third subgroup 27c is formed by conductors 12 and 22, with conductor 12 serving as a first phase conductor and conductor 22 serving as a second phase conductor.

[0069] The second subgroup 27b is formed by two conductors 13, 23, through which a control signal is provided, which can be used in particular to control the lighting modules 40, 50 and / or 60. The control signal is in particular a DALI signal. In a variant, however, it can be provided that the conductors 13, 23 provide control signals based on another suitable protocol.

[0070] In the track lighting system, the first adapter 30, 30', 30" can be specifically configured according to a first type designated as 30, a second type designated as 30' or a third type designated as 30". The first adapter 30, 30', 30" inserted into the second area 5 inside the interior area 3 is configured to contact the conductors 12-14 and 22-24 respectively. When inserted and electrically coupled to the track 1, the adapter 30, 30', 30" preferably contacts all conductors 12-14, 22-24. To this end, the adapter 30, 30', 30" is equipped with contact units 312, 313, 314 and 322, 323, 324, which can be pivoted out from the side of its housing, for example configured as pivotable contact tongues; see Figure 3 and Figure 5 With regard to the contact conductors 12 - 14 , 22 - 24 , the first adapters 30 , 30 ′, 30 ″ are configured in the same way.

[0071] The first area 4 is open to the outside and is configured to accommodate one or more flat, elongated, linear lighting modules 40, for example forming a light strip, in such a way that the lighting modules 40 for direct lighting (also called linear inserts) are substantially flush with the visible side edge 9 of the track 1; see Figure 2 .

[0072] A first adapter 30 of the first type makes it possible to power and control a lighting module 40. After the adapter 30 has been inserted, in the side region facing the first region 4, the adapter 30 has contact elements 41 which can come into contact with corresponding contact elements of the lighting module 40 in order to power it and control it.

[0073] Each side wall 2 a of the rail 1 is provided with an engagement geometry 42 in a portion 43 inside the first region 4 . In the embodiment shown in the drawings, the engagement geometry 42 is partly groove-shaped and partly rib-shaped, enabling locking and fastening of the lighting module 40 .

[0074] Figure 3 The second type of adapter 30' is shown inserted into the second inner region 5, which differs from the first adapter 30 in that the contact element 41 is omitted in the adapter 30'. Instead, the adapter 30' has a contact portion ( Figure 3 The contact portion 51 is provided with a contact element 51 which contacts a corresponding contact element of the indirect lighting module 50 to supply it with electrical energy and enable it to be controlled. The indirect lighting module 50 is accommodated in a third area 6 which is arranged on the side of the web 2b facing away from the second area 5 of the interior and is Figure 3The indirect lighting module 50 is snapped into the area 6 .

[0075] Figure 4 A third type of adapter 30'' is shown inserted into the interior second area 5, which enables provision and control of a lighting module 60 configured as an adjustable spotlight 60. The lighting module 60 is pivotally connected to a rod-shaped connector 65 and coupled to the adapter 30'' via the connector 65, which is rotatably mounted on the adapter 30''.

[0076] The first adapter 30" Figure 5 1 is shown in part with the housing opened, as an example, to illustrate the contacting and phase selection of the conductors 12 - 14 , 22 - 24 , which are provided in the same manner as the first adapter 30 , 30 ′.

[0077] The adapter 30, 30', 30" has a rotating part 35, which is specifically partially formed into a cylindrical shape, on which contact units 312, 313, 314 and 322, 323, 324 configured as contact tongues are arranged. When the adapter 30, 30', 30" is inserted into the second area 5, the rotating part 35 can rotate around an axis extending parallel to the depth direction T. In this way, the contact units 312-314, 322-324 can be swung out of the housing of the adapter 30, 30', 30", or enter the housing of the adapter 30, 30', 30" through the relevant opening. When swung out (see Figure 1-4 ), contact units 312, 313, 314 contact conductors 12, 13 and 14 respectively, and contact units 322, 323, 324 contact conductors 22, 23 and 24 respectively. The three contact units 312-314 and the three contact units 322-324 are respectively arranged on two opposite longitudinal sides of the adapter 30, 30', 30", and can be swung out for contact.

[0078] The swivel component 35 is connected to the sliding control element 351 via a mechanism so that, by moving the sliding control element 351, the swivel component 35 can be rotated between a contact position of the contact units 312-314, 322-324 pivoted out and a non-contact position of the contact units 312-314, 322-324 pivoted in. When the adapter 30, 30', 30" is inserted into the second area 5, the sliding control element 351 is accessible to an operator through the first area 4. The adapter 30, 30', 30" can be additionally fixed by a pivotable portion of the swivel component 35 and / or by means of a latching element.

[0079] The adapter 30, 30', 30" also has a phase selection unit 36, which is equipped with a rotary selection switch, which can be rotated around an axis parallel to the depth direction T by a rotary control element 361 in the inserted state. When the adapter 30, 30', 30" is inserted, the operator can still access the rotary control element 361. By mechanically rotating the rotary selection switch, the phase L1, L2 or L3 for powering the lighting module 40, 50 or 60 can be selected as needed or required, and can be electrically connected to a converter such as the first adapter 30, 30', 30".

[0080] The converter of the first adapter 30 , 30 ′, 30 ″ is not shown in greater detail in the figures and converts the alternating current absorbed by the conductor unit 7 to provide a low voltage to the lighting modules 40 , 50 , 60 according to the selected phase L1 , L2 or L3 .

[0081] The track 1 is further configured to receive a second adapter 70 a - d , 70 for contacting the conductors 11 , 21 of the second set 28 and / or the conductors 15 , 25 of the third set 29 . Figure 6-10 Second adapters 70a-70d and 70 according to the first to fifth types are shown. The second adapters 70a-d, 70 are used in each case to realize special or additional functions of the lighting device constructed on the basis of the modular track lighting system. For this purpose, an electric module 80 is electrically coupled to the adapters 70a-d, 70. The module 80 can be configured as an emergency lighting module or an illuminable emergency information module or an illuminable indication module. Alternatively, the module 80 can be configured as a loudspeaker module or a sensor module. Figure 6-11 In the example, module 80 is configured as an emergency lighting module, such as an electrically illuminated emergency information board, which highlights, for example, escape routes, emergency exits, etc., and can also provide emergency lighting, and is coupled to the second adapter 70a-d, 70 via a connector 85.

[0082] The outer geometry of the second adapter 70 a - d , 70 corresponds substantially to the outer geometry of the first adapter 30 , 30 ′, 30 ″. However, the adapters 70 a - d , 70 differ from the adapters 30 , 30 ′, 30 ″ with regard to the contacting of the conductor element 7 .

[0083] according to Figure 6 The second adapter 70a of the first type has on its two longitudinal sides pivotable contact units 715 and 725 for contacting the conductors 15 and 25 of the third group 29 and pivotable contact units 713 and 723 for contacting the conductors 13 and 23 of the first group 27.

[0084] In the configuration of the track 1 shown in the figures, the conductor 21 is arranged as a phase conductor for providing a phase of a first dedicated AC circuit, and the conductor 11 is arranged as a neutral conductor of the first dedicated AC circuit. In addition, the conductor 25 is arranged as a phase conductor of a second dedicated AC circuit, and the conductor 15 is arranged as a neutral conductor of the second dedicated AC circuit. The first and second dedicated AC circuits can each provide AC as an operating current for an additional function, for example at a nominal voltage of 230 V and a frequency of 50 Hz. For example, the second group 28 and the third group 29 can be powered by one or more different energy sources from the first group 27, which is used for the main lighting function.

[0085] By means of a second adapter 70a of the first type, the module 80 provides additional functions, such as emergency lighting and / or illuminated signs, supplied with electrical energy from a second dedicated AC circuit of the third group 29. Control may be effected via the existing DALI conductors 13,23, for example.

[0086] In accordance with Figure 7 In the second adapter 70b of the second type in FIG. 1 , the contact units 713, 723 are omitted, so that no control is performed via the DALI conductors 13, 23. This makes a simple adapter 70b possible, for example, if the module 80 is to be operated without the need for a controller.

[0087] according to Figure 8 The third type of second adapter 70 c has pivotable contact units 711 and 721 on its two longitudinal sides for contacting the conductors 11 and 21 of the second group 28 , and pivotable contact units 713 and 723 for contacting the conductors 13 and 23 of the first group 27 .

[0088] By means of a second adapter 70c of the third type, the module 80 provides additional functions, such as emergency lighting and / or illuminated signs, supplied with electrical energy from the first dedicated AC circuit of the second set 28. Control may be effected via the existing DALI conductors 13,23, for example.

[0089] In accordance with Fig. 9 In the fourth type of second adapter 70d in FIG. 1 , the contact units 713, 723 are omitted again from the third type of second adapter 70c, so that no control is performed via the DALI conductors 13 and 23. This in turn makes a simplified adapter 70d possible.

[0090] Fig.10 The fifth type of second adapter 70 is shown in a perspective view with the housing opened. The fifth type of second adapter 70 combines Figure 6-9All contact options of the first to fourth types of second adapters described in the embodiment of the present invention are available, so the fifth type of second connector 70 can be selected as needed. Therefore, the second adapter 70 provides greater flexibility in use.

[0091] The fifth type of second adapter 70 has a rotating part 75, whose structure is configured to be basically similar to the rotating part 35 of the adapter 30, 30', 30", and when the second adapter 70 is inserted into the second area 5, it can be pivoted by the operator through the sliding control element 751. Unlike the first adapter 30, 30', 30", the rotating part 75 only carries two contact units 713, 723, which are arranged in a central position and are configured as contact tongues, similar to the contact units 313, 323, so as to selectively contact or not contact the two conductors 13, 23 according to the position of the sliding control element 751 and the final rotation position of the rotating part 75.

[0092] Furthermore, the second adapter 70 of the fifth type has a pivoting part 77 which can be pivoted like a rocker about an axis extending parallel to the depth direction T when the second adapter 70 is inserted. Tongue-shaped contact units 711, 721, 715, 725 are arranged on the pivoting part 77 in such a way that the contact units 711, 715 on one longitudinal side of the second adapter 70 and the contact units 721, 725 on the other longitudinal side can be pivoted out through the associated housing opening. The pivoting part 77 comprising the contact units 711, 715, 721, 725 is arranged in such a way that the conductors 11, 21 can be contacted by the contact units 711, 721 or the conductors 15, 25 can be contacted by the contact units 715, 725, but not all the conductors 11, 15, 21, 25 are contacted simultaneously. Thus, the pivoting part 77 can also select a dedicated or emergency power supply circuit. For insertion into the track 1 or removal from the track 1, the pivoting part 77 is brought into the center position. The pivoting of the pivoting part 77 can be achieved by means of a sliding control element 771 which is accessible to the operator when the second adapter 70 is inserted and which is connected to the pivoting part 77 by means of a mechanism not shown in detail.

[0093] Starting from the second adapter 70 according to the fifth type, a second adapter 70 having the contact function of the second adapters 70b, 70d of the second and fourth types, for example, can be formed by omitting the rotating part 75, so as to selectively and alternatively contact the second group 28 or the third group 29. Moreover, in a further modification, by additionally omitting the contact units 711, 721 or 715, 725, the second adapter 70b can be used only for contacting the third group 29, or the second adapter 70d can be used only for contacting the second group 28. However, if the contact units 711, 721 or 715, 725 are omitted from the pivoting part 77, and the rotating part 75 is also provided, a second adapter 70a for contacting the third group 29 and selectively also contacting the DALI conductors 13, 23, or a second adapter 70c for contacting the second group 29 and selectively also contacting the DALI conductors 13, 23 can be formed. Figure 6-9 The contact situation shown can also be selectively achieved by using a fifth type of second adapter 70 .

[0094] The second adapter 70a - d , 70 may include a converter to operate the module 80 at a low voltage.

[0095] In a variant of this embodiment, the second group 28 and / or the third group 29 can be allocated and used differently than described above. For example, it can be provided that only the conductors 11, 21 of the second group 28 provide the zero or phase of a dedicated AC circuit, or only the conductors 15, 25 of the third group 29 provide the zero or phase of a dedicated AC circuit, and correspondingly, the two conductors 15, 25 of the third group 29 or the two conductors 11, 21 of the second group 28, for example, provide the positive and negative poles of the DC circuit at a DC voltage of 24V. For example, it is conceivable to power the DC circuit by means of a battery in order to retain dedicated or additional functions in the event of a power failure, such as the lighting of an information board with an emergency light. It should be understood that in other variants, both the second group 28 and the third group 29 can each provide the poles of an associated one of the two DC circuits.

[0096] In addition, the conductors 11, 21 of the second group 28 and / or the conductors 15, 25 of the third group 29 can be used to provide signals for additional functions instead of using a power supply using AC or DC. The module 80 can be configured as a sensor module or a speaker module, for example, instead of a lighting panel or an emergency light. In these variations, the conductors 11, 21 and / or 15, 25 can transmit signals from the sensor module through the second adapter 70a-d, 70, or provide audio signals to the speaker module through the second adapter.

[0097] It will be appreciated that one of the second and third groups 28, 29 may be used for this type of signal and the other of the second and third groups 28, 29 may be used for emergency or dedicated operating current in the form of alternating current or direct current.

[0098] Fig.11 1 shows a lighting device 100 by way of example, comprising a track 1, adapters 30 and 70a inserted into an inner area 3, a lighting module 40 electrically coupled to the first adapter 30 for a main lighting function, and a module 80 electrically coupled to the second adapter 70a, the module 80 being configured as an illuminable emergency information module. The lighting module 40 is powered and controlled by the first adapter 30 based on the alternating current and signal provided by the first group 27. For example, the module 80 is powered by the second adapter 70a based on a separate circuit provided by the third group 29 (see also Figure 6 ), the second adapter 70a can also control the module 80 according to the DALI signal applied to the conductors 13, 23 of the first group 27. Therefore, the module 80 provides the additional function of separate power supply.

[0099] The adapters 30 , 30 ′, 30 ″ with associated lighting modules 40 , 50 , 60 and the adapters 70 a - d , 70 with associated modules 80 of different types may be combined in various ways along the track 1 and may occur multiple times.

[0100] Specifically, from Figure 1-4 As can be clearly seen from Figures 6-9, the arrangement of the first group 27, the second group 28 and the third group 29, the first group 27 having six conductors, is located between the second group 28 and the third group 29, and the second group 28 and the third group 29 each have two conductors, which allows the track 1 to be compactly constructed. At the same time, different types of first adapters 30, 30', 30" can be used to implement the lighting function as the main function of the track lighting system, for example by means of lighting modules 40, 50, 60. In addition, different types of second adapters 70, 70a-d can be used in the same track 1, which are connected to the conductors 11, 21 of the second group 28 and / or the conductors 15, 25 of the third group 29, and in some variations also to the conductors 13, 23. At the same time, for example, the first adapters 30, 30', 30" can also be used without problems for simpler tracks having only conductors corresponding to those in the first group 27, and standard adapters configured for simpler tracks of this type can also be used for the track 1, as described above with reference to FIG. Figure 1-11 As described above, a high flexibility and versatility of the track lighting system is thus achieved.

[0101] Although the invention has been fully described above with the aid of preferred exemplary embodiments, the invention is not restricted thereto but can be modified in many ways.
