Description

Technical Field

[0001] This invention relates to the field of lighting arrangements, particularly for lighting purposes in buildings (e.g., their interiors). More particularly, this invention relates to the field of track-mounted luminaire systems. This invention relates to an adapter for a track-mounted luminaire system and a lighting arrangement including such an adapter. Background Technology

[0002] Various implementations of track systems for lighting purposes are known. For example, systems have been proposed that integrate electrical conductors into the track profile to provide a power supply voltage. Such track-mounted luminaire systems, exemplarily, can include various types of luminaire inserts, such as spotlight or linear luminaire inserts; wherein these inserts can also be combined.

[0003] Adapters are known to be able to be introduced into a track, obtain operating current and control signals through longitudinally extending conductors, and be used to operate electrical connections for functional elements (particularly luminaires / luminaire inserts). For example, such an adapter is described in AT 527 716 A1.

[0004] Known adapters can be introduced along a track to selectable locations, and the devices of these adapters designed for this purpose can be brought into separable contact positions, thereby ensuring fixed electrical and mechanical connections. Requirements for the contact mechanisms of such adapters may, exemplarily, involve: reliable contact, space-saving construction within a constrained adapter body, ease of use, reduction in the number of required parts, avoidance of wear during long-term use, easy disconnection capability, and so on. In many cases, various known designs selectively consider only a portion of the above aspects.

[0005] For example, EP 3 544 127 A1 describes an adapter having movable electrical contact elements that extend by rotating a single camshaft; wherein each contact element is pushed into its extended position by a cam.

[0006] For example, WO 2021 116 939 A1 and EP 4 518 047 A2 describe a connection device for a lighting system with an electrified track, wherein an operating mechanism is provided with a slider and a rod for translational movement. Displacement of the slider causes translation of the rod, which in turn causes rotation of the rotatable body. The displacement of the slider exposes the electrical contacts from the housing.

[0007] AT 526 097 A2 also describes an adapter for a track-mounted lighting system, wherein a contact element can be moved between a contact position and a non-contact position by a movable operating element. This patent describes the contact element being mounted on a carrier rotatably within an adapter housing, and the rotation of the carrier being caused by the displacement of the operating element.

[0008] The linear, linear displacement of the operating element, such as that described in AT 526 097 A2, has proven advantageous for the operability of the adapter. For example, such an operating element can be easily operated by the operator without tools and can achieve reliable contact with electrical conductors positioned in the track.

[0009] However, it was found that converting linear sliding motion into rotational motion requires a relatively large number of individual parts, which also introduces a considerable amount of work when assembling such an adapter.

[0010] DE 2 210 516 A describes another adapter for a conductor rail having retractable and extendable contact and retaining members. The adapter has a movable slider with an actuator for controlling the retraction and extension of the contact and retaining members. Summary of the Invention

[0011] Against this backdrop, the object of the present invention is to provide an adapter that enables separable and reliable contact of the track conductor device, is easy to operate, and can be manufactured with minimal effort and at a low cost. Accordingly, an improved lighting arrangement is also proposed.

[0012] According to the invention, this objective is achieved by an adapter having the features of claim 1 and / or by a lighting arrangement having the features of claim 22.

[0013] Accordingly, an adapter for a track-mounted lighting system is proposed. The adapter is specifically implemented to be inserted into the track of the track-mounted lighting system. The track has a conductor assembly with conductors, the adapter has contact elements, and in the inserted state, each conductor or selected conductor can be contacted via the contact elements.

[0014] Each contact element has a contact portion that can be moved to a contact position and a non-contact position. In the contact position, the contact portion extends from the adapter to make electrical contact with an associated conductor. In the non-contact position, the electrical contact between the contact element and the associated conductor is interrupted.

[0015] In the adapter of the present invention, each contact element has an elongated shape. Each contact element may be specifically implemented as an elastic element and is fixedly clamped relative to the housing of the adapter in the fastening portion of the contact element.

[0016] The adapter according to the invention has at least one movably configured operating and control element having a control geometry. Each contact element mates with a region of the control geometry, and each contact portion can be moved between a contact position and a non-contact position by the operator moving the operating and control element and by the local mechanical contact between the respective contact element and the mating region of the control geometry.

[0017] The present invention also proposes a lighting arrangement having a track, at least one lighting device or lighting module, and at least one adapter according to the invention for coupling the lighting device or lighting module to the track using a conductor device.

[0018] One concept of this invention is to achieve mobility of the contact portion for contacting the conductor by constructing the contact element as a fixedly clamping elastic element, thereby significantly reducing not only the number of individual components required but also the assembly labor. This avoids the need for rotatable or pivotable support systems for individual components. In this invention, this is advantageously combined with movable operating and control elements that enable simple and convenient operation. By associating the control geometry formed on the operating and control elements with the contact elements, even complex sequences of contact portion movements can be achieved without complex mechanisms having multiple individual components. Instead, a large portion of this complexity can be transferred to the control geometry formed on a single component and the areas that respectively mate with the contact elements.

[0019] Thus, the present invention provides an easy-to-operate adapter that is easy to manufacture and assemble due to the significantly reduced number of individual parts, which also helps to reduce manufacturing costs. In this way, the reliability of the adapter can also be further improved, and wear during long-term use is reduced by avoiding mechanisms with a large number of individual moving parts.

[0020] Thus, the adapter according to the present invention provides an easy-to-operate, separable and reliable contact method, while reducing the number of parts, saving costs and further extending the service life of the adapter.

[0021] Advantageous constructions and further improvements of the invention are disclosed in the other dependent claims and in the description with reference to the accompanying drawings.

[0022] In one configuration, the operating and control elements are arranged to be linearly displaceable by the operator relative to the housing. Therefore, the operation of the operating and control elements is simple and straightforward.

[0023] According to a further improvement, the operating and control elements are configured to be displaceable along the longitudinal direction of the adapter, which is substantially parallel to the longitudinal direction of the track when the adapter is inserted. In this way, sufficient space is provided for displacement movement even in slender and / or narrow adapters.

[0024] In one configuration, the contact elements are specifically implemented as bending springs. Such contact elements can easily and conveniently provide elastic rebound movement of the contact portions between their contact and non-contact positions.

[0025] According to one configuration, each contact element is specifically implemented with a substantially constant rectangular cross-section in the main portion between its contact portion and fastening portion. This facilitates the space-saving arrangement of multiple such contact elements in a compact adapter.

[0026] In one configuration, the contact elements are arranged and implemented such that, in the plugged-in state of the adapter, each contact element extends substantially along the longitudinal direction of the track in its primary extension direction in the non-contact position. Therefore, the mounting space available along the longitudinal direction of the track in a slender system can be well utilized to accommodate the elastic elements serving as contact elements. The elastic dimensions and elastic stroke can be advantageously selected according to the intended function without being severely limited by excessively constrained mounting space.

[0027] According to a further improvement, each contact element has a control protrusion that mechanically interacts with a mating control geometry region during movement of the operating and control elements. In this way, the control protrusion can sensitively detect the control geometry in the mating region during movement of the operating and control elements. This enables more complex motion sequences at the contact points.

[0028] In another further improvement, the contact portion of each contact element is specifically implemented with a protruding contact tongue, and the contact tongue and control protrusion project from the contact element in opposite directions. Therefore, contact of the conductors and movement of the contact portions controlled for this purpose can occur on different sides of the contact element, thereby enabling particularly good utilization of installation space.

[0029] In one configuration, each contact element is formed from a strip of conductive material, and the control protrusion preferably extends from this strip in a V-shape. The bending of the control protrusion simplifies its manufacture. If the control protrusion is bent into a V-shape, it has a relatively small peak region between the two inclined portions, which, exemplarily, can be rounded with a small radius. This V-shaped control protrusion can precisely follow the control geometry and further facilitates the realization of desired, optional, and complex sequences of contact portion movements.

[0030] In a further improvement: An elongated first strip-shaped region of the contact element is provided between the contact portion and the control protrusion, which is preferably substantially straight in the relaxed state; and / or, A second strip-shaped region of contact elements is provided between the fastening portion and the control protrusion, the strip-shaped region being at least partially, preferably substantially, straight in the relaxed state; and / or, Each contact portion is specifically implemented at the free end of the contact element, and each control protrusion is disposed between and spaced apart from the contact portion and the fastening portion.

[0031] The first and second strip regions are preferably arranged elastically, particularly as part of a bending spring. If the control protrusion is deflected by the control geometry and the contact portion moves to its contact position, the first strip region between the control protrusion supported on the control geometry and the contact portion can still elastically yield, thereby allowing not only contact between the contact portion and the associated conductor of the conductor device, but also, when the control protrusion is deflected to its maximum extent, to abut against the conductor under the action of a spring force. This achieves particularly reliable contact. Simultaneously, the second strip region enables a spring effect during the deflection of the control protrusion from its position when the contact element is relaxed, such that when the deflection of the control protrusion returns through the control geometry, the control protrusion returns to its relaxed position under the spring effect of the second strip region, and the contact portion reliably returns to its non-contact position. The spacing between the control protrusion and the contact portion, and the spacing between the control protrusion and the fastening portion, contribute to achieving the spring effect described on both sides of the control protrusion.

[0032] In one configuration, the individual contact elements are fixedly clamped onto an associated carrier. In this configuration, the carrier is fixedly arranged on the adapter's circuit board. This allows the contact elements to be reliably and simultaneously secured relative to the adapter's housing at their fastening portions with minimal assembly effort. In particular, the carrier can be automatically and with minimal effort secured to the circuit board, and preferably, an electrical connection is also established between the circuit board conductors and the contact elements, for example, by soldering.

[0033] In a preferred further improvement, the operating and control elements for moving the contact portion can be operated by the operator without tools. In particular, the operating and control elements can be manually moved without the use of tools. This makes the operation of contacting or disconnecting the conductor device particularly simple, reliable, and convenient for the operator. This is especially advantageous when working in ceiling areas, particularly at heights above head level.

[0034] According to one configuration, the operating and control elements can be operated by the operator by touching the outer surface of the adapter, which is arranged on or toward the open side of the track in the inserted state.

[0035] In particular, in one configuration, the operating and control elements can be partially flush with and partially recessed relative to a flat surface that forms the outer surface of the adapter located on the open side of the track or facing that side. This simplifies operation while maintaining a compact adapter structure.

[0036] In a further improvement, the adapter is implemented as an insert rail such that, in the inserted state, the conductors extend laterally, particularly on both sides, of the adapter, and the respective contact portions protrude laterally from the adapter in the contact position. In this way, the rail can be equipped with multiple conductors in a space-saving arrangement, and these conductors can be made in contact.

[0037] In particular, the conductors are arranged parallel to each other, and they can come into contact with the contact portion.

[0038] In a further improvement, the operating and control element has a plate-like portion on or within a first main surface region where engagement geometry (particularly for manual engagement) is implemented, and a control member, with control geometry implemented on the control member, rises in a wall-like manner from a second main surface region opposite the first main surface region of the plate-like portion. In this way, the engagement geometry and the control member are clearly separated, although they are still arranged together in a single element of the adapter. The plate-like portion also enables convenient displaceable guidance of the operating and control element and helps prevent accidental contact with the contact element from outside the adapter.

[0039] In one configuration, the joining geometry located on or within the first main surface region of the plate-like portion may be specifically implemented with transverse ribs rising from the first main surface region. Such transverse ribs are advantageously operable manually by an operator.

[0040] According to a further improvement, the contact element includes a contact element for obtaining operating current (especially alternating current) from the conductor device and / or a contact element for obtaining control signals (especially DALI signals), the contact portion of the contact element being movable between a contact position and a non-contact position by displacement of the operating and control elements.

[0041] Specifically, the conductors that can be contacted by the contact element are configured to provide power voltage and / or control signals to the lighting fixtures or lighting modules of the track-mounted luminaire system.

[0042] In one configuration, the operating and control elements can be displaced to two or more preset displacement positions, wherein control geometry and contact elements are configured, and the contact elements are arranged such that, depending on one of the displacement positions adopted by the operating and control elements, the contact portions of selected contact elements associated with the corresponding displacement position are located at the contact position. In this way, a variety of different contact configurations of the adapter can be achieved, which are adopted by simply and conveniently selecting the displacement positions.

[0043] The displacement positions can be arranged continuously from the positions of the operating and control elements associated with the adapter's disconnect configuration (where all contact parts are in their non-contact positions), or optionally on either side of the positions associated with the disconnect configuration. In this way, different operational concepts can be implemented as needed.

[0044] According to one configuration, a preset displacement position allows the adapter to couple with one of a plurality of electrical phase lines provided by a conductor device by selecting the displacement position, so as to supply power via the selected phase line to components coupled to or coupled to the adapter (in particular lighting devices or lighting modules) for their operation. Accordingly, a separate device for selecting the phase line to be used is unnecessary, thereby further simplifying the adapter's structure.

[0045] In another further improvement, the operating and control elements can be displaced to at least one preset displacement position, wherein the control geometry and contact elements are configured and arranged such that when the operating and control elements adopt this displacement position, the contact portion of each contact element is in its contact position. Exemplarily, this may be advantageous if all contact elements are intended to simultaneously contact the associated conductors. In this case, exemplaryly, the contact elements associated with the operating and control elements may be used only to contact the control signal conductor and / or may only connect one phase and one neutral line of the AC circuit. Exemplarily, the neutral line and one phase line of the AC circuit may be connected, and the control signal may be connected. Optionally, in this case, in a further configuration where two or more phase lines are simultaneously connected, a separate phase selection device, such as a phase selection switch, may be provided in or on the adapter.

[0046] In a further improvement, the operating and control element is provided with a first locking geometry, and the inner side of the housing is provided with a second locking geometry. The first and second locking geometries are engageable in a separable locking engagement when the operating and control element moves. In particular, in another further improvement, the first and second locking geometries are engageable in a separable locking engagement with each other when the operating and control element moves to at least one preset displacement position or at least one of the preset displacement positions (preferably two or more or all of the preset displacement positions), allowing the operator to tactilely perceive when each preset displacement position is reached. This makes it easier for the operator to identify when the operating and control element has reached the desired position during operation. Furthermore, the interaction of the locking geometries can also provide a stop to prevent accidental displacement of the operating and control element upon slight contact.

[0047] In another further improvement, exemplarily, the first locking geometry may be implemented with a locking recess provided on the operating and control elements, and the second locking geometry may be implemented with a locking lug disposed inside the housing. For example, the locking lug may be provided on a portion of the housing wall having a reduced wall thickness. Thus, tactile feedback can be implemented in a simple, space-saving, and efficient manner.

[0048] In one configuration, the adapter has at least one retaining element, preferably two or more; the retaining elements are releasably locking into the track when the adapter is inserted. In this configuration, the adapter is configured such that disengagement of at least one retaining element is blocked in the displacement position of the operating and control elements (where one or more contact portions are in their contact position). The releasable locking engagement of the retaining elements provides simple and quick mechanical retention of the adapter in the track, which is convenient for the operator and, exemplarily, facilitates work in ceiling areas. Blocking / locking the retaining elements in the displacement position associated with the contact configuration prevents the adapter from being pulled out when the contact portions are in conductive contact with their respective associated conductors. This contributes to further enhanced safety and prevents accidental damage to the adapter and / or the track.

[0049] Specifically, the retaining element is implemented and arranged to resiliently recoil toward the interior of the adapter housing, and the recoil of the retaining element for disengaging the adapter from the track can be blocked / locked by a blocking portion of the operating and control element, which moves to the rear of the retaining element by displacement of the operating and control element within the housing. In this way, the blocking / locking function is achieved with less labor and fewer parts.

[0050] In a further improvement, the displacement directions of the operating and control elements and the movement directions of each contact portion as it moves between a contact position and a non-contact position both lie within an imaginary plane, wherein the imaginary planes associated with each contact element are substantially parallel to each other. In this further improvement, the control geometry specifically implements control contours associated with the contact elements in its segments along the imaginary planes, each control contour having contour portions extending parallel to and inclined to the displacement directions; and / or the control geometry specifically implements guiding devices capable of guiding the respective associated contact elements to perform elastic bending movements within the associated imaginary planes. The expected sequence of movements corresponding to the contact portions can be reliably and accurately achieved.

[0051] In one configuration, the control geometry can move along at least two contact elements by displacement of the operating and control elements; and / or the contact elements are divided into two groups, and the control geometry can move along the contact elements between a first group and a second group by displacement of the operating and control elements. Specifically, the contact elements are arranged and clamped such that, when the operating and control elements are displaced, the contact portions of those contact elements arranged on opposite sides of the control geometry can elastically pivot from a non-contact position to a contact position, and vice versa, with each pivoting in the same or opposite directions. In this way, the operating and control elements can advantageously and space-savingly be used to extend the contact portions to reach corresponding contact positions on both sides of the adapter, and / or space-savingly bring multiple contact portions into contact and non-contact positions.

[0052] In a further improvement, the contact portions of the first set of contact elements each extend from the adapter from the first longitudinal side of the adapter in their contact positions, and the contact portions of the second set of contact elements each extend from the adapter from the second longitudinal side of the adapter opposite to the first longitudinal side in their contact positions.

[0053] In one configuration, the operating and control elements are integrated into a single unit. Specifically, the operating and control elements can be integrally formed from an electrically insulating material (preferably an electrically insulating plastic material). This integral formation means that the operating and control elements can be easily operated and installed into the adapter with minimal effort. When the operating and control elements are made of an electrically insulating material (especially plastic), the contact elements can directly contact the control geometry without requiring additional insulation at this contact point.

[0054] In a further improvement, the operating and control elements can be injection molded, particularly integrally injection molded. This enables the economical mass production of the operating and control elements, and consequently, the adapter.

[0055] The above-described constructions and further modifications can be combined arbitrarily within a meaningful scope. Other possible constructions, further modifications, and implementations of the invention include combinations of features of the invention not explicitly mentioned above or below with reference to exemplary embodiments. In particular, those skilled in the art can add various aspects as improvements or supplements to the corresponding basic forms of the invention. Attached Figure Description

Detailed Implementation

[0060] Figure 1-8 illustrates an adapter 1 according to a first exemplary embodiment for use in a track-mounted luminaire system. The track-mounted luminaire system, exemplarily, can be used to illuminate a room (not shown) in a building.

[0061] Adapter 1 is used to insert into track 2 of the track-mounted lighting system. Figure 16-19 The diagram schematically illustrates an elongated track 2, which has at least partially a channel-shaped cross-section, such that the opposing sidewalls and bottom of the track 2 define an elongated interior 7. A longitudinal side 10 of the track 2 is open, allowing access to the interior 7 of the track 2, particularly allowing the insertion of the adapter 1. In this case, the open side 10 of the track 2 is also accessible after the track 2 is installed, particularly from the room to be illuminated.

[0062] Track 2 has a conductor device 3 with conductor 4, wherein, see Figure 16 The conductors 4 extend parallel to each other and parallel to the longitudinal direction 17 of the track 2. In this case, the conductors 4 are preferably arranged in two groups on both sides of the interior 7 of the track 2; and, exemplary, are held by insulating internal carrier profiles, which are each arranged in a region of one of the opposite sidewalls of the track 2. Thus, once the adapter 1 is inserted into the interior 7 of the track 2, the conductors 4 extend on both sides of the adapter 1.

[0063] Conductor 4 preferably includes a conductor for providing a power supply voltage, particularly an AC voltage, for operating the lighting fixture 50 and / or lighting module 51, such as an AC voltage rated in the range of about 100 volts to about 240 volts and with a frequency in the range of about 50 Hz to about 60 Hz. Preferably, conductor 4 also includes other conductors for providing at least one control signal (e.g., a DALI signal) for the lighting fixture 50 and / or lighting module 51 of the track-mounted luminaire system. However, alternatively, control signals based on other suitable protocols may also be provided.

[0064] The adapter 1 may be elongated and have a box-shaped housing 8, which is formed by snapping together two housing parts 8a and 8b, which are made of plastic material; exemplary, they may be injection molded.

[0065] Figure 1 Figure 3-6 shows the first end region of adapter 1. Figure 2A-2C A first operating and control element 6 for the first end region of adapter 1 is shown.

[0066] In the first end region, see Figure 1 The adapter 1 has four contact elements 5, each contact element 5 being configured to contact one of the four selected conductors 4, which is associated / mates with the adapter 1, when the adapter 1 is inserted into the rail 2. This can be achieved by... Figure 1 The conductors 4 that are contacted by the contact element 5 shown are conductors that provide operating current in the form of alternating current. The neutral conductor can be contacted by one of the contact elements 5, while Figure 1 The other three contact elements 5 can each contact one phase conductor (also referred to as L1, L2, L3).

[0067] like Figure 1 As shown, adapter 1 has a simple construction in the first end region, with a few individual components. Within housing component 8a, a portion of circuit board 24 is shown, which has electrical and / or electronic components and wires that can be used to conduct, switch, control, and / or transform the acquired operating voltage to power lighting device 50 and / or lighting module 51. Figure 1 Two electrically insulated carriers 9 are also shown, wherein on each carrier 9, two contact elements 5 are respectively fixedly clamped by fastening portions 5b of the contact elements 5. Furthermore, in the first end region, the adapter 1 has operating and control elements 6 arranged displaceably relative to the housing 8 along the longitudinal direction 25 of the adapter 1. When the adapter 1 is inserted into the track 2, the longitudinal direction 25 of the adapter 1 is parallel to or coincides with the longitudinal direction 17 of the track 2.

[0068] Optionally, each contact element 5 can be an elastic element, which can be a bending spring made of a conductive material strip. Optionally, each contact element 5 has an elongated basic shape, and the specific shape and exact length of each contact element 5 can be different. The common features of the contact elements 5 are described below.

[0069] Optionally, the fastening portion 5b of the contact element 5 can be the end region of the contact element 5; for example, the fastening portion 5b can be molded into the corresponding carrier 9, or fastened thereto in an interlocking and / or non-interlocking manner, such as being securely locked or securely attached to the carrier 9.

[0070] In the end region opposite to the fastening portion 5b, each of the contact elements 5 has a contact portion 5a; optionally, the contact portion 5a has a contact tongue 5z protruding laterally from the contact element 5. Therefore, the contact portion 5a is provided at the free end of the contact element 5.

[0071] Each contact element 5 has a substantially constant rectangular cross-section between the contact portion 5a and the fastening portion 5b. In the region between the contact portion 5a and the fastening portion 5b, a V-shaped control protrusion 5c extends from the conductive material strip of the contact element 5. Figure 1 As shown, in each contact element 5, the contact tongue 5z and the control protrusion 5c protrude from the contact element 5 in opposite directions.

[0072] Between the contact portion 5a and the control protrusion 5c, each contact element 5 has an elongated first strip-shaped region 5d, which is substantially straight in the relaxed state. Furthermore, between the fastening portion 5b and the control protrusion 5c, each contact element 5 has a second strip-shaped region 5e, which is substantially straight in at least some areas in the relaxed state. Thus, the control protrusion 5c is spaced apart from the contact portion 5a by the first strip-shaped region 5d and from the fastening portion 5b by the second strip-shaped region 5e.

[0073] Optionally, the operating and control element 6 can be a one-piece component made of electrically insulating plastic. For example, the operating and control element 6 can be integrally injection molded. Figure 2A-2C Various perspective views of the first operating and control element 6 are shown.

[0074] The first operating and control element 6 has an elongated plate-like portion 13, which forms a first main surface region 14 and a second main surface region 15. The first main surface region 14 is provided with engagement geometry 16 for manual engagement by an operator; see, for example, [link to relevant documentation]. Figure 2A-2C The joining geometry 16 has transverse ribs rising from the first main surface region 14. Outside of the transverse ribs, the first main surface region 14 is substantially flat.

[0075] In the assembled state of adapter 1, the operating and control element 6 is disposed within adapter 1 such that some areas of the transverse ribs and the first main surface region 14 are accessible from the outside of housing 8 through opening 8c. Opening 8c is disposed in a region of the outer surface 11 of adapter 1, which is accessible through the open side 10 of track 2 when adapter 1 is inserted into track 2. Exemplarily, the outer surface 11 can retract into the interior 7 of track 2 and face the open side 10. Therefore, the first operating and control element 6 can be operated by an operator accessing it from the outer surface 11, particularly when adapter 1 is inserted into track 2.

[0076] The second main surface region 15 of the plate-like portion 13 is located on the side opposite to the first main surface region 14, and therefore faces the interior of the housing 8 in the assembled state of the adapter 1. A control member 20 rises from the second main surface region 15 in a wall-like manner. Optionally, the control member 20 has a control geometry 21, the function of which will be explained below.

[0077] The contact elements 5 located in the first end region of the adapter 1 are divided into two groups, with two contact elements 5 in each group. They are each fixedly clamped to a common carrier 9 at the fastening part 5b, as shown in the figure. Figure 1Viewed longitudinally 25 from the adapter 1, two carriers 9 are arranged on either side of the recess 24a of the circuit board 24 and are each fixedly connected to the circuit board 24. The two carriers 9 are fastened to the circuit board 24 from the same side. In other words, the two carriers 9 are placed on the same main surface of the circuit board 24, thereby simplifying machine assembly via the circuit board 24, such as via SMT (Surface Mount Technology) machines. Therefore, the carriers 9 can be automatically arranged and fixed onto the circuit board 24. Furthermore, the contact elements 5 can simultaneously and automatically make electrical contact with corresponding wires on the circuit board 24 via machine, for example, by soldering. The resulting automation and machine assembly capabilities reduce manual assembly operations and associated costs, and avoid assembly errors. For example, Figure 3A The arrangement of carrier 9 is shown.

[0078] In the assembled state of adapter 1, contact element 5 and first operating and control element 6 are arranged in the first end region of adapter 1 such that control member 20 is located between two sets of contact elements 5.

[0079] The operating and control element 6 is displaceably guided within the housing 8, allowing the operator to manually move the operating and control element 6 relative to the housing 8 linearly and in the opposite direction of displacement V6 without tools, using the engagement geometry 16, for example, see... Figure 4A The displacement direction V6 is parallel to the longitudinal direction 25 of adapter 1, and this direction is also parallel to the longitudinal direction 17 of track 2 when adapter 1 is inserted.

[0080] Furthermore, in the assembled adapter 1, when the contact elements 5 are relaxed, the main extension direction 23 of each contact element 5 is substantially parallel to the longitudinal direction 25 of the adapter 1. In this state of the contact elements 5, when the adapter 1 is inserted into the track 2, all these main extension directions 23 of the contact elements 5 extend substantially along the longitudinal direction 17 of the track 2, provided that the adapter 1 is not in a contact configuration in the first end region.

[0081] When the operator moves the operating and control element 6, the control geometry 21 acts on the contact element 5. A preset area 22 of the control geometry 21 is associated with / cooperates with each contact element 5; however, for clarity, not all areas 22 are shown with reference numerals in the figure. By displacing the operating and control element 6, the control geometry 21 can move along the contact elements 5 between the first set and the second set.

[0082] The shape of the control geometry 21 allows each contact portion 5a to move between a contact position and a non-contact position by means of the displacement of the operating and control element 6 and the local mechanical contact between the contact element 5 and the respective mating regions 22.

[0083] In its contact position, each contact portion 5a protrudes laterally from the adapter 1 on one longitudinal side, toward the conductor 4 arranged on that side inside the adapter 1 when the adapter 1 is inserted. In the contact position, the contact tongue 5z makes electrical contact with the conductor 4 that mates with the contact element 5, wherein the elastic spring effect of portion 5d allows the contact tongue 5z to elastically abut against the conductor 4, thereby achieving reliable electrical contact.

[0084] When the contact portion 5a is in its contact position, a portion of the contact element 5 protrudes outward from the housing 8 through the corresponding elongated narrow through hole 8d on the housing 8.

[0085] On the other hand, in the non-contact position of the contact portion 5a, the contact element 5 is relaxed, or at most rests against the control geometry 21 with a slight force. In this state, the contact element 5 does not protrude through the through hole 8d, and the contact tongue 5z retracts into the housing 8, thereby interrupting the electrical contact with the conductor 4 that mates with the track 2.

[0086] The geometry and orientation of each contact tongue 5z are selected to enable reliable contact with the mating conductor 4, and the contact tongue 5z can enter through any available narrow inlet slot in the insulator carrying the conductor 4.

[0087] The movement of each contact element 5 is described below using one of the contact elements 5 as an example.

[0088] Contact element 5 is fixedly clamped relative to housing 8 at fastening portion 5b. When operating and control element 6 moves a sufficient displacement distance, i.e., moves to a preset displacement position relative to housing 8, viewed from the longitudinal center plane of adapter 1, control protrusion 5c deflects outward through mechanical contact between control protrusion 5c and region 22 of control geometry 21 that mates with contact element 5. This causes contact tongue 5z and at least part of strip region 5d to be exposed through through hole 8d. This is in Figures 3A to 6A The accompanying drawings illustrate this exemplarily. Optionally, the control geometry 21 may be configured such that the contact portions 5a of different contact elements 5 are brought into the contact position at different displacement positions of the operating and control element 6. Under the control of the control geometry 21, if the deflection of the control protrusion 5c of the preset contact element 5 returns after a preset displacement distance, the contact element 5 returns to the housing 8 and its contact portion 5a is in the non-contact position. This return to the housing 8, in other words, the movement into the non-contact position, is caused by the restoring spring force of each contact element 5.

[0089] For example, Figure 2A-2C A complex control geometry 21 is shown for the first operating and control element 6, which defines and causes the motion sequence of the contact element 5 when the operating and control element 6 is displaced.

[0090] Figure 4B The movement direction B5 of the contact portion 5a of the selected contact element 5 is shown as an example for all contact elements 5. The displacement direction V6 of the operating and control element 6 and the movement direction B5 of each contact portion 5a as it moves from a non-contact position to a contact position (or vice versa) both lie within an imaginary plane E56. Here, at least the same group of contact elements 5, i.e., contact elements 5 located on the same side 21c or 21d of the control geometry 21, are associated with different planes E56, but these planes E56 are all parallel to each other. However, in Figure 1 In -6, the contact elements 5 of the control geometry 21, which are opposite each other and can extend from different longitudinal sides of the adapter 1, use the same plane E56 in pairs, but this is not mandatory depending on the conductor configuration of the track 2. Figure 4B A plane E56 is shown that is parallel to the plane of the drawing.

[0091] In each region 22, the control geometry 21 defines a control profile 21a in a section intersecting with one of the planes E56, which in Figure 5A The control contour 21a is illustrated by dashed lines. It includes a contour portion extending parallel to the displacement direction V6 and rising and falling contour portions extending at an angle to the displacement direction V6. When the operating and control element 6 is displaced, the control protrusion 5c follows the control contour 21a. In this way, the deflection of the control protrusion 5c in the plane E56 is caused or eliminated by the tilted contour portion, while the deflection position can be maintained by the parallel contour portion, exemplarily.

[0092] Viewed in a direction perpendicular to plane E56, for the operating and control element 6, the guide profiles 21a are each located between two ridge-shaped guide devices 21b, between which the portion of the contact element 5 can move in both the non-deflection stationary state and during deflection. Therefore, the guide devices 21b more reliably prevent accidental deflection of the contact portion 5a transverse to plane E56 and ensure that the elastic bending movement of the contact element 5 occurs within plane E56. This ensures more reliable contact with the conductor 4.

[0093] Because the two sets of contact elements 5 are clamped on different narrow sides of the recess 24a (for example, see...) Figure 1 and Figure 3AThe geometry of the contact element 5 and its interaction with the control geometry 21 allow the contact portions 5a of those contact elements 5 arranged on opposite sides 21c and 21d of the control geometry 21 to elastically pivot from a non-contact position to a contact position or vice versa when the operating and control element 6 is displaced. Furthermore, the pivoting directions are the same for rotational movements in the same direction. However, the contact element 5 does not pivot as a whole; instead, the pivoting movement is achieved through the elastic deflection of the free end of the contact element 5 with the contact portion 5a, while the fastening portion 5b remains fixedly clamped relative to the housing 8.

[0094] Adapter 1 is used to supply power to the lighting device 50 or lighting module 51 for its operation. Furthermore, adapter 1 is configured to receive control signals from conductor device 3. Adapter 1 may be configured to interpret the control signals and control the lighting device 50 or lighting module 51 coupled or coupled to adapter 1 according to the control signals. Alternatively, adapter 1 may be configured to forward the control signals to the lighting device 50 or lighting module 51, in which case the control signals may be interpreted by the lighting device 50 or lighting module 51 itself.

[0095] In the first terminal region of the adapter 1 described in detail above, the contact element 5 is combined with the operating and control element 6 to enable contact with the desired phase conductor of the conductor device 3 for operation of the lighting device 50 or lighting module 51, and also to contact the neutral conductor. Therefore, the first terminal region is used to obtain operating power.

[0096] Figure 3-6 shows that, starting from the initial position shown in Figure 3, the first operating and control element 6 can move along the displacement direction V6 to three consecutive preset displacement positions, denoted as I, II and III.

[0097] Figures 3A-3D The position of the first operating and control element 6 corresponds to the disconnected configuration of the adapter 1. In this configuration, the adapter 1 can be inserted into or removed from the track 2. In the disconnected configuration, all contact portions 5a retract to their non-contact positions. The adapter 1 can be mechanically locked in the track 2 by means of the elastic yielding retaining elements 29a, 29b in the first end region of the adapter 1 and the elastic yielding retaining element 29c in the second end region of the adapter 1. When the adapter 1 is inserted, the retaining elements 29a, 29b, and 29c each engage with the track 2 in a separable locking engagement.

[0098] Figures 4A-4C The first displacement position shown corresponds to the first contact configuration of the adapter 1 in the first end region, wherein the contact portions 5a of the two preset contact elements 5 are each transferred to the contact position. This is achieved through two protruding contact tongues 5z (see...). Figure 4B( ), thus enabling contact with conductor 4, one of which is the first phase conductor and the other is the neutral conductor.

[0099] Figures 5A-5C The second displacement position shown corresponds to the second contact configuration of the adapter 1 in the first end region, wherein the contact portions 5a of the other two selected contact elements 5 are each transferred to the contact position. This is achieved through two protruding contact tongues 5z (see...). Figure 5B ( ), thus being able to contact conductor 4, one of which is the second phase conductor, and the other is still the neutral conductor.

[0100] Figures 6A-6C The third displacement position shown corresponds to the third contact configuration of the adapter 1 in the first end region, where the contact portions 5a of two additional selected contact elements 5 are each transferred to the contact position. This is achieved through two protruding contact tongues 5z (see...). Figure 6B ( ), thus being able to contact conductor 4, one of which is the third phase conductor, and the other is still the neutral conductor.

[0101] Therefore, the contact portion 5a of the contact element 5 that contacts the neutral conductor extends in all three displacement positions of Figures 4, 5 and 6, while the contact portion 5a used to contact the phase conductor is different in each case.

[0102] Therefore, depending on the displacement position adopted by the operating and control element 6, the contact portion 5a of the selected contact element 5 associated with the displacement position is respectively located in the contact position in the first end region of the adapter 1. By selecting the first, second, or third displacement position of the first operating and control element 6, the adapter 1 can be electrically coupled to one of the three electrical phases provided by the conductor device 3 to supply power to the lighting device 50 or lighting module 51 via the selected phase for its operation. For this purpose, a separate phase selection switch is not required, thereby simplifying the construction of the adapter 1 and reducing costs.

[0103] Furthermore, adapter 1 is configured in its second-end region to contact the conductors 4 that provide control signals in order to obtain control signals. Exemplarily, the control signals may be DALI signals.

[0104] Figures 7 and 8 show the second terminal region of adapter 1 in different views and states. The contact of the working current conductor is similar to that in the first terminal region, but the contact in the second terminal region is simplified in comparison.

[0105] In the second end region, two contact elements 5 are provided; optionally, they are substantially the same as those in the first end region and are fixedly clamped to a common insulating carrier 9. (Refer to reference...) Figure 1The carrier 9 described in -6 is the same as that described in the previous section. The carrier 9 is fastened to the same main surface of the circuit board 24, wherein the contact element 5 is also in electrical contact with the corresponding wires of the circuit board 24.

[0106] The second operating and control element 6' is movable along the longitudinal direction 25 of the adapter 1 and has a plate-like portion 13; optionally, the first main surface area 14 of the plate-like portion 13 has a joining geometry 16 with transverse ribs for manual tool-free operation by the operator. A control member 20' rises in a wall-like manner from the second main surface area 15 of the plate-like portion 13. Control members 20' are equipped with control geometries 21' on both sides in a manner similar to that described above for control members 20. Since only one contact element 5 is provided on each side of the control member 20', the control geometry 21' is simplified by omitting the aforementioned guiding device, but still has a control profile for each contact element 5. A region 22' of the control geometry 21' mates with each contact element 5.

[0107] In the second end region, the control geometry 21' can move along the two contact elements 5 by moving the operating and control element 6' between the two contact elements 5. In the second end region, the two contact portions 5a are elastically pivoted in and out in a rotational manner in opposite directions, especially because the two contact elements 5 are clamped onto the same carrier 9.

[0108] Through the two contact elements 5 in the second end region (see Figures 7 and 8), the relevant conductor 4 carrying the control signal can be simultaneously contacted. For this purpose, the operating and control element 6' has a rest position or a starting position, which corresponds to the disconnected configuration of the adapter 1 in the second end region. Figure 7A and 7B This configuration is shown. Furthermore, the operating and control element 6' also has a displacement position corresponding to... Figures 8A-8D The contact configuration is shown.

[0109] Figure 9-11 An adapter 101 according to a second exemplary embodiment is shown. Figure 9 Figures 10 and 11 show a first end region of adapter 101, in which contact is made for obtaining operating current from conductor device 3 for lighting device 50 or lighting module 51. In a second end region, adapter 101 may be configured to obtain control signals, as described in detail above with reference to Figures 7 and 8.

[0110] The second exemplary embodiment is a variation of the first exemplary embodiment; therefore, the differences from the first exemplary embodiment will only be explained in detail below. For further details beyond the explanations below, please refer to the above section regarding... Figure 1 -6 is a description.

[0111] In the second exemplary embodiment, four contact elements 5 are also provided in the first end region. However, the adapter 101 has a displaceable operating and control element 106 in the first end region, the control geometry of which is configured such that the center position of the operating and control element 106 (see...) Figure 9 Corresponding to the disconnected configuration, in which all contact elements 5 in the first end region are retracted, i.e., the contact portions 5a of all contact elements 5 are in their non-contact positions. The first or second displacement positions of the operating and control element 106 are located on either side of this central position, making a first contact configuration and a second contact configuration possible, wherein in these contact configurations, two contact portions 5a on the same longitudinal side of the adapter 1 each protrude toward the mating conductor 4 located there.

[0112] In the second exemplary embodiment, the current acquisition provided in the first terminal region is as follows: Figure 9-11 As shown, it can be used, by way of example, to contact the phase and neutral lines of two completely independent AC circuits, or, in a conceivable alternative variation, to contact the positive and negative terminals of two independent DC circuits.

[0113] Figures 20-22 show an adapter 501 according to a variant of the second exemplary embodiment. Figure 20B-20D Figures 21 and 22 show the first end region of adapter 501, wherein the operating mode of adapter 501 in the first end region corresponds to the operating mode of adapter 101 in the first end region.

[0114] In the variant of Figures 20-22, the acquisition of control signals in the second terminal region of adapter 501 is omitted by way of example (see Figure 20-22). Figure 20A (This part is missing from the original text and can be omitted.) The following section describes adapter 501 and... Figure 1-1 The differences between the adapters of type 0 are explained in the text above for further details.

[0115] An operating and control element 506, located in the first end region of adapter 501 and movable along the displacement direction V6, has a control geometry 521 on its control member 520. The displacement of the operating and control element 506 enables adapter 501 to achieve both a disconnected configuration and first and second contact configurations. The center position of the operating and control element 506 (see...) Figure 20A-20D This again corresponds to the disconnect configuration. Figures 22A-22B The first displacement position, denoted as I, is shown, corresponding to the first contact configuration, while Figures 21A-21C The second displacement position, denoted as II, is shown and corresponds to the second contact configuration. Similar to adapter 101, the first and second displacement positions are located on either side of the center position corresponding to the disconnect configuration.

[0116] Here, the control member 520 can move along the displacement direction V6 between two sets of contact elements 5 (each set has two contact elements 5, which are fixedly clamped relative to the housing 8 at the fastening portion 5b), thereby allowing the control geometry 521 to act on the V-shaped control protrusions 5c of the contact elements 5 respectively.

[0117] Contact element 5 is as described above. Figure 1-1 As described in the exemplary embodiment of 0, the difference is that in the exemplary embodiment of Figures 20-22, the contact element 5 is additionally provided with an arcuate region 5f (see Figure 20C In this region, the contact element 5 follows an arc-shaped curved path before transitioning to the fastening portion 5b. The fastening portion 5b and the arc-shaped region 5f together form two oppositely curved curves 5m and 5n.

[0118] The contact element 5 described above, shown in Figures 20-22, and having an arcuate region 5f and the resulting curves 5m, 5n, can also be used in variations for all other exemplary embodiments of the invention described above or below.

[0119] An adapter 201 according to a third exemplary embodiment is shown in Figures 12-15. In the adapter 201, contacts for obtaining operating power and contacts for obtaining control signals are both implemented in the first end region of the adapter 201. Therefore, the contacts shown in Figures 7-8 are omitted in the second end region of the adapter 201.

[0120] The differences between adapter 201 and adapter 1 in the first exemplary embodiment in the first end region are explained in detail below. For further details beyond the following explanation, please refer to the information regarding the first exemplary embodiment (…). Figure 1 Explanation of -6).

[0121] Six contact elements 5 are provided in the first end region of adapter 201, which are implemented as described above. Figure 1 As described in section -6. The six contact elements 5 are arranged in two groups of three, each group consisting of three contact elements 5, which are fixedly clamped to a common insulating carrier 9. The carrier 9 is fixed to the circuit board 24, located on the same main surface, and adjacent to surfaces similar to... Figure 1 The edge of the recess 24a shown.

[0122] An integrated, electrically insulated operating and control element 206 is linearly displaceable within the housing 8 of the adapter 201 and is accessible from the outer surface 11 of the adapter 201 for manual, tool-free operation by the operator. Similar to the first exemplary embodiment, the operating and control element 206 has a control member 220 with control geometry 221 on both sides. In the third exemplary embodiment, the control geometry 221 is configured such that when the operating and control element 206 moves along the displacement direction V6, it can induce a preset sequence of movements in the contact portions 5a of the six contact elements 5.

[0123] Figure 12-15 shows that, starting from the initial position shown in Figure 12, the operating and control element 206 can be moved along the displacement direction V6 to three consecutive preset displacement positions, again referred to as I, II, and III.

[0124] Figure 12A-12I The position of the operating and control element 206 corresponds to the disconnected configuration of the adapter 201, in which the adapter 201 can be inserted into or removed from the rail 2. In the disconnected configuration, all contact portions 5a retract to their non-contact positions.

[0125] Similar to the first exemplary embodiment, the adapter 201 can be detachably and mechanically locked in the track 2 by means of the elastic yielding retaining elements 29a, 29b in the first end region of the adapter 201 and the elastic yielding retaining element 29c in the second end region of the adapter 201, which are not shown separately in the figure.

[0126] Figures 13A-13D The first displacement position shown corresponds to the first contact configuration of the adapter 201 in the first end region, wherein the contact portions 5a of the four pre-selected contact elements 5 are each transferred to the contact position. This is achieved through two protruding contact tongues 5z (see, for example...). Figure 13B This allows contact with conductors 4, one of which is the first phase conductor and the other is the neutral conductor. Two other conductors 4 in contact are conductors that provide control signals.

[0127] Figures 14A-14D The second displacement position shown corresponds to the second contact configuration of the adapter 201 in the first end region, wherein the contact portions 5a of four additional selected contact elements 5 are each transferred to the contact position. This is achieved via four protruding contact tongues 5z (see...). Figure 14B The conductor 4 is made accessible, and one of the conductors 4 is the second phase conductor. In addition, in the second contact configuration, the neutral conductor and the two conductors 4 that provide control signals are also made accessible.

[0128] Figures 15A-15CThe third displacement position shown corresponds to the third contact configuration of the adapter 201 in the first end region, where the contact portions 5a of four additional selected contact elements 5 are each transferred to the contact position. This is achieved through the protruding contact tongue 5z (see...). Figure 15B The conductor 4 is made accessible, and one of the conductors 4 is the third phase conductor. In addition, in the third contact configuration, the neutral conductor and the two conductors 4 that provide control signals are also made accessible.

[0129] In the third exemplary embodiment (see Figure 13B-15B The two contact elements 5 in the middle of each longitudinal side of the adapter 201, that is, the two contact elements 5 in the middle of each of the two sets of contact elements, can be configured to acquire control signals.

[0130] Therefore, the contact portion 5a of the contact element 5 that contacts the neutral conductor and the contact portion 5a of the contact element 5 that contacts the conductor 4 that carries the control signal are in the contact position in all three displacement positions in Figures 13, 14 and 15, while in order to connect the phase line, another contact portion 5a is in the contact position.

[0131] For example, Figure 14A and 14B As shown, similar to the first exemplary embodiment, in the third exemplary embodiment, the control geometry 221 also has a control profile 21a and a guide device 21b.

[0132] As described with respect to the first exemplary embodiment, retaining elements 29a, 29b, and 29c are also provided on the housing 8 of the adapter 201. Each retaining element 29a-29c is preferably integral with the housing component 8a or 8b and has the shape of a locking tongue, with a locking element with a sliding ramp on its elastically resilient free end.

[0133] Regarding the retaining element 29c in the second end region of the adapter 201, please refer to FIG8, which exemplarily illustrates the retaining element 29c, which is also applicable to the first and second exemplary embodiments.

[0134] For example, in Figure 12D and 12F The retaining element 29a is shown in detail, and the two sliding ramps are designated 30 and 31. When the adapter 201 is introduced into the interior 7 of the track 2, the sliding ramp 31 abuts against the inner longitudinal edge or rib of the track 2, causing the retaining element 29a to elastically yield and lock into place after being fully pushed into the interior 7. The sliding ramp 30 allows the adapter 201 to be disengaged from the track 2 by simply pulling it. The retaining element 29b is arranged in the same manner as the retaining element 29a.

[0135] When adapter 201 is in the disconnected configuration in the first end region, in other words, when operating and control element 206 is in the disconnected configuration... Figure 12A-12I When the disconnection configuration is in the position shown, the elastic return of the aforementioned retaining element 29a is possible.

[0136] Figure 12F , 12G Figures 12H and 12I show a space 32 inside the housing 8, with the retaining element 29a being part of the housing wall. The space 32 is located behind the retaining element 29a, particularly behind the region of the free end of the retaining element 29a that carries the sliding ramp 30. The retaining element 29a can retract into this space 32 when an external force is applied. This retraction allows the adapter 201 to be locked during assembly and unlocked during disassembly in the track 2.

[0137] If the operating and control element 206 is moved from the position shown in FIG. 12 to one of the first to third displacement positions shown in FIG. 13, 14 and 15, then, as described above, a predetermined number of contact portions 5a each move to a contact position. Simultaneously, the blocking portion 40 of the operating and control element 206 (preferably an integral structure with the plate-like portion 13, for example, see...) Figure 12A As the displacement movement occurs, it moves into the space 32 behind the retaining element 29a. In this way, the blocking portion 40 is located between the two retaining elements 29a that are opposite each other on the housing 8, thereby preventing the two retaining elements 29a from retracting and releasing. Therefore, as long as the adapter 201 is in one of the contact configurations in the first end region, the adapter 201 inserted into the track 2 is prevented from being removed from the track 2 and is additionally prevented from falling out.

[0138] In the first exemplary embodiment, the retaining element 29a can be locked by operating and controlling the blocking portion 40 of the element 6 in the same manner as described above for the adapter 201. In the first and third exemplary embodiments, the retaining element 29b is not locked at any displacement position, nor is the retaining element 29c locked.

[0139] A similar principle can be applied to the second exemplary embodiment, such that a blocking portion 40, similar to the blocking portion 40 of the operating and control element 6 or 206, is disposed at both ends of the operating and control element 106 when viewed in its longitudinal direction. Thus, in the second exemplary embodiment, depending on the displacement position, when the displacement reaches... Figure 10A When the displacement position is on the left, the holding element 29b can be locked, or when the displacement reaches... Figure 10A When the displacement position is on the right, the retaining element 29a can be locked.

[0140] This mode of operation is shown in Figures 20-22 for adapter 501 according to a variant of the second exemplary embodiment. Figure 20DThe space 32 inside the housing 8 is shown, which allows the retaining elements 29a, 29b to move elastically into the housing 8. Figure 21C A blocking portion 541 of the operating and control element 506 is shown, which locks the retaining element 29a in the second displacement position of the operating and control element 506, while Figure 22B A blocking portion 542 of the operating and control element 506 is shown, which locks the retaining element 29b in a first displacement position of the operating and control element 506. Therefore, in both contact configurations of the adapter 501, the adapter 501 is mechanically locked to prevent it from being pulled out of the rail 2. For the adapter 501, in the first displacement position, the retaining element 29a is not locked, and in the second displacement position, the retaining element 29b is not locked. In the disconnected configuration (see FIG. 20), all retaining elements 29a, 29b are released.

[0141] Furthermore, in adapter 501, operating and control element 506 has an extension 566 on one side viewed along the longitudinal direction 25 of adapter 501; exemplaryly, extension 566 may be plate-shaped; exemplaryly, extension 566 extends beyond plate-shaped portion 13, plate-shaped portion 13 carrying engagement geometry 16 in its first main surface region 14. Extension 566 is provided with symbols to indicate whether adapter 501 is in a disconnected configuration or in a configuration where at least partially retaining elements 29a, 29b are locked, these symbols are provided on a surface region aligned with and capable of extending the first main surface region 14. Exemplarily, these symbols may be formed by printing, molding, or embossing. Symbols corresponding to the appropriate applicable configuration are visible from the outer surface 11 through display window 518 on adapter 506 housing 8, while other symbols not applicable in a given position of operating and control element 506 are obscured by the surrounding housing wall. Here, display window 518 is formed by opening 8f, which is circular in the variant shown in Figures 20-22. The opening 8f is arranged in the longitudinal direction 25 adjacent to but independent of the opening 8c that enables manual displacement of the operating and control element 506.

[0142] The extension 566 and the blocking portions 541, 542 of the adapter 501 are preferably integrally connected to the plate-shaped portion 13.

[0143] Furthermore, in the above exemplary embodiments, tactile feedback is provided to the operator to indicate tactilely that a preset displacement position or a position corresponding to a disconnected configuration has been reached for the operating and control elements 6, 106, 206, or 506. The following explanation uses adapter 201 as an example, and this explanation, with appropriate modifications, is also applicable to the first and second exemplary embodiments.

[0144] The operating and control element 206 has guide steps 206b on its two opposing narrow longitudinal edges 206a formed on the plate-like portion 13. These guide steps, in the assembled state of the adapter 201, engage behind the internal protrusion 286 of the housing 8 to guide displacement movement in the direction V6. Furthermore, on each longitudinal edge 206a, the operating and control element 206 also has a first locking geometry 36, which forms a plurality of locking recesses 37 arranged in a predetermined manner and corresponding to defined positions of the operating and control element 206. The locking recesses 37 are symmetrically arranged on the two longitudinal sides 206a of the operating and control element 206.

[0145] The housing 8 has a second locking geometry 38 on the inner side of portion 286. Exemplarily, this geometry can be a locking lug integrally formed on portion 8e of the housing wall, which has a reduced wall thickness and is therefore more flexible. When the operating and control element 206 is displaced to a position corresponding to the disconnected configuration and each of the first, second, and third displacement positions, the locking lug of the locking geometry 38 can engage in a locking manner with each similar locking recess 37. The interaction of the locking geometries 36, 38 makes it easy for the operator to perceive when a preset position has been reached, and also provides a stop to prevent accidental displacement of the operating and control element 206.

[0146] Figure 16 The steps of inserting adapter 201 into track 2 through its open side 10 to establish the lighting arrangement are schematically shown. Adapter 201 is aligned parallel to track 2 and pushed into its interior 7 in the direction of arrow P, see... Figure 16 .

[0147] Lighting arrangement 300 shown Figure 17 The device includes a track 2 and an adapter 201, which is mechanically fixed to and electrically coupled to the lighting device 50. Through the adapter 201, the lighting device 50 is coupled to, powered, and driven by the conductor device 3. In the example shown, the lighting device 50 is a spotlight or strobe lamp; other types of lighting devices are also applicable.

[0148] Figure 18 Another lighting arrangement 400 is shown. The adapter 201 is again inserted into the track 2. Exemplarily, the lighting module 51 and the adapter 201 are respectively introduced into and held on the track 2, and the lighting module 51 and the adapter 201 are disconnectably electrically coupled. The lighting module 51 is also powered and controlled by the adapter 201. Therefore, the adapter 201 couples the lighting module 51 to the conductor device 3.

[0149] Figure 19The steps of the adapter 201 disassembly process are shown. Once the operating and control element 206 is moved to its starting position (corresponding to the disconnected configuration), all contact portions 5a retract into the housing 8. Furthermore, the previously locked retaining element 29a can freely and elastically retract into the housing 8. Therefore, by initiating a pull on the first end, the adapter 201 can tilt out of the track 2, thereby also causing the other retaining elements 29b, 29c to disengage.

[0150] exist Figure 16-19 In this case, adapter 1, adapter 101 or adapter 501 can be used instead of adapter 201.

[0151] Optionally, in variations of the first, second, and third exemplary embodiments described above, the control geometry of the operating and control elements 6, 106, 206, or 506 and the contact elements 5 may be configured such that only one disconnect position and one preset displacement position can be achieved. In such variations, the contact portions 5a of all the contact elements 5 simultaneously move to the contact position when the operating and control elements move to the displacement position. The adapter according to such variations is then each provided with a separate phase selection switch or circuit selection switch, through which the phase line for powering the lighting device 50 or the lighting module 51 or the circuit for this purpose can be selected.

[0152] Figures 23A-23D 24A-24B and Figure 25 An adapter 601 according to a fourth exemplary embodiment is shown. The adapter 601 is configured to be inserted into a track 2 having a channel-shaped cross-section, wherein, according to the fourth exemplary embodiment, in the region of the opposite sidewalls of the track 2, the interior 7 of the track 2 is provided with four conductors 4, divided into two groups of two conductors 4 each.

[0153] Exemplary, according to the fourth exemplary embodiment, the phase conductor and the first control signal conductor of the AC circuit are disposed adjacent to one sidewall of the track 2, while the neutral conductor and the second control signal conductor of the AC circuit are disposed adjacent to the other sidewall. Therefore, in the fourth exemplary embodiment, the track 2 provides only one AC circuit and one control signal; optionally, the AC circuit provides an AC voltage with a rated voltage in the range of about 100 volts to about 240 volts and a frequency in the range of about 50 Hz to about 60 Hz. Exemplary, the control signal conductor may apply a DALI signal or a control signal based on other suitable protocols.

[0154] With adapter 601 inserted, all four conductors 4 can be simultaneously contacted by the four contact elements 5. To achieve this, by manually moving the operating and control element 606 in direction V6 without tools, the contact portions 5a of all four contact elements 5 can move from their non-contact position to their contact position in a single movement step, and vice versa. This is achieved through the interaction of the control protrusions 5c of the contact elements 5 (similar to those described above) with the respective mating regions 622 of the control geometry 621 of the control member 620 of the operating and control element 606.

[0155] Figures 23A-23D An adapter 601 is shown, which is in the Figure 23B The end is in a disconnected configuration and the operating and control element 606 is in a state corresponding to the disconnected configuration. In the disconnected configuration, all contact portions 5a are in their non-contact positions. Furthermore, for the adapter 601, the operating and control element 606 can take a preset displacement position, which corresponds to... Figures 24A-24B The contact configuration of adapter 601 is shown. Figures 24A-24B In the contact configuration, the contact portions 5a of all contact elements 5 are in their contact positions, thus enabling contact with the phase conductor, the neutral conductor, and the control signal conductor. Since only one phase of an AC circuit is provided according to the fourth exemplary embodiment, the adapter 601 does not provide a phase selection switch.

[0156] Regarding the construction of the contact element 5, please refer to the explanation provided above in conjunction with the foregoing embodiments. For the adapter 601, the contact element 5 is further provided with a slit arrangement 5s in the transition region between the control protrusion 5c and the linear first strip region 5d; optionally, the slit arrangement 5s in the fourth exemplary embodiment includes two parallel slits, providing additional elastic flexibility to the contact element 5 in this transition region. For the adapter 601, another slit arrangement 5t formed in a similar manner is provided in the curved transition region within the contact element 5 near the fastening portion 5b. As described in more detail above, each of the contact elements 5 is fixedly clamped at the fastening portion 5b by the carrier 9.

[0157] Similar to the exemplary embodiments in Figures 20-22, a display window 618 is provided in the fourth exemplary embodiment.

[0158] The first locking geometry 36 formed on the operating and control element 606 can engage with the second locking geometry 38 formed on the housing 8 in a releasable locking manner, similar to the above description, either at the initial position of the operating and control element 606 in FIG. 23 corresponding to the disconnected configuration, or at the preset displacement position of the operating and control element 606 in FIG. 24 corresponding to the contact configuration.

[0159] As in the exemplary embodiments described above, adapter 601 includes retaining elements, of which retaining elements 29a and 29b are shown in Figures 23 and 24. In the disconnected configuration of Figure 23, each retaining element 29a, 29b is released to allow for resilient retraction, while in the contact configuration of Figure 24, retaining element 29a is blocked by a blocking portion 640 of the operating and control element 606, which prevents retaining element 29a from resiliently retracting into the housing 8.

[0160] In addition to adapter 201, adapter 601 can also be used Figure 16-19 In this case, the number of conductors 4 in track 2 is adjusted accordingly.

[0161] The slit arrangements 5s and / or 5t provided according to the fourth exemplary embodiment can be implemented in further variations as well as in other exemplary embodiments described above.

[0162] Although the present invention has been described above based on preferred exemplary embodiments, the present invention is not limited thereto, but can be modified in many different ways.
