Description

[0001] The present invention relates to a connector for an elongated support profile for a lighting fixture support track system, and a lighting fixture support track system having such a connector.

[0002] Lighting support track systems are known in the prior art, such as the applicant's TECTON system. Such lighting support track systems typically have elongated support profiles, which may be arranged in series or branching directions to form lighting support track systems of arbitrary length or branching. Any lighting support track assembly, such as a strip light, can be mechanically coupled to the support profile from below. Electrical conductors are typically arranged within the support profile, allowing the lighting support track assemblies to be electrically connected to these conductors, thereby enabling the supply of power (e.g., for operation) or data (e.g., for control).

[0003] If multiple support profiles are combined into a system, adjacent support profiles are typically mechanically connected to each other. Thus, the support profiles can be arranged in I-shape, L-shape, T-shape, or X-shape, and mechanically coupled to each other via built-in connectors (e.g., plate connectors).

[0004] Mechanical connectors are often equipped with electrical connection components, thus requiring the highest possible mating precision.

[0005] Because such systems require highly diverse components, customizing a specific luminaire support track system often necessitates combining support profiles of different specifications and lengths with luminaire support track assemblies of similarly different specifications and lengths. To achieve a closed system in length, multiple different lengths are often required for each type of luminaire support track assembly. The resulting gaps are typically covered using (partially custom-cut) blind flanges.

[0006] The connection type of the support profile and the power supply method required by the system (input power supply; output power supply) ultimately affect the connection points of the system and the types of connectors that need to be provided, which further increases the number of components.

[0007] All of these factors increase the complexity of the entire lighting support track system, whether in terms of planning, production, transportation, storage, or assembly.

[0008] Therefore, the purpose of this invention is, on the one hand, to increase assembly possibilities, and on the other hand, to reduce component complexity.

[0009] This objective is achieved through the subject matter of the independent claims. The dependent claims improve upon the central idea of ​​the invention in a particularly advantageous manner.

[0010] According to a first aspect, the present invention relates to a connector for an elongated support profile for a lighting fixture support track system. The connector herein has an elongated profile portion that extends along a longitudinally extending axis with a defined cross-section and restricts a receiving space.

[0011] The cross-section here has two side legs arranged on either side of the longitudinal extension axis to form two sidewalls of the profile portion opposite to the longitudinal extension axis. Each of these sidewalls has a longitudinal end face portion extending along the longitudinal extension axis. These two longitudinal end face portions together define (particularly laterally define) a receiving opening for the receiving space of the profile portion, or unfold the receiving space. The cross-section also has a connecting leg that connects the two side legs to form a connecting wall of the profile portion. The connecting wall also at least partially or completely restricts the receiving space on the side of the sidewall opposite to the receiving opening. In other words, the profile portion has a substantially uniform cross-section (e.g., a U-shaped or V-shaped cross-section) along its length.

[0012] The profile portion also has retaining profiles that each extend toward the receiving space from two adjacent longitudinal end face portions in a supportive manner to hold the luminaire support track assembly, which is at least partially inserted into the receiving space in the radial direction (i.e., in the radial direction about the longitudinal extension axis), in a supportive manner.

[0013] The retaining profile is spaced apart from the axial end face of the profile portion in the axial direction (i.e., in the axial direction about the longitudinal extension axis), the axial end face being open to allow the slender support profile of the luminaire support track system to pass through, so that the cross section of the profile portion is unobstructed between the longitudinal end face portions in the area between the end face and the retaining profile; that is, the opening is accommodated across the entire width.

[0014] The connector according to the invention makes it possible to optimally mimic the common profile of a support profile. Since the connector is designed to accommodate the support profile, i.e., to externally surround the support profile to be connected or accommodated, a connection that is not only aesthetically pleasing but also mechanically robust is possible. Because the connector also has a retaining profile, it can be used (as is typically the case with support profiles) to support corresponding luminaire support rail assemblies. Therefore, preferably, the connector can functionally continue the support profiles in accommodating any luminaire support rail assembly. Since the retaining profile is axially spaced from the end face, the area between the retaining profile and the end face can be easily, preferably also (axially) variably used (preferably in a supporting manner) to accommodate support profiles passing through the end face. Because the connector externally surrounds the support profile, it can only cover at most the axial end edge of the accommodated support profile. This is particularly advantageous, for example, when the customer cuts the support profile to the desired length for a personalized setting, as the resulting cut edges can be covered and hidden by the connector. Therefore, the end face of the support profile (e.g., the equivalent of a cut edge) can be safely concealed, both for aesthetic reasons and to hide any potentially sharp cut edges. Depending on the distance from the profile to the end face, a correspondingly variable, i.e., telescopic connection area can be provided relative to the support profile, thereby allowing the length of the luminaire support track system to be variably adjusted in this manner.

[0015] Within the framework of this invention, the "defined cross section" is preferably understood to mean that the cross section has a substantially consistent shape and size along the longitudinal extension axis at least in the functional area (i.e., the location for accommodating the luminaire support track assembly, i.e., from the end face to the axial end of the retaining profile or accommodating the opening), thus making it possible in a simple manner to accommodate support profiles that are also mostly uniformly constructed and extended; preferably also in a sliding or telescopic manner.

[0016] In the region between the end face and the retaining profile, the longitudinal end face portion can preferably be formed as a rib extending partially forward of the receiving space within the receiving opening (i.e., preferably within the plane spanned by the receiving opening). These ribs here particularly preferably have longitudinal end edges pointing towards each other. In this way, a compact but effective clamping element is formed that easily surrounds the support profile received in the receiving space on the receiving opening side, thereby reliably retaining the support profile (radially). This preferably avoids, as much as possible or completely, the use of additional fastening means, such as screws or riveting.

[0017] The profile portion can preferably be designed in such an irregular shape that the profile element has a fixed profile so as to (preferably at least radially) support the support profile to be housed therein. Such an irregular design makes it possible that the corresponding support profile (e.g., having a similar profile) can be easily housed in the connector in a form-fitting manner along a direction perpendicular to the longitudinal extension axis, and thus preferably held therein in a fall-proof manner.

[0018] The fixed profile can be formed, for example, by a shaped connecting wall. This allows for mechanical connection using a profile that is often also provided in the corresponding supporting profile. Thus, the shaped connecting wall can fix the supporting profile inwards and preferably be used outwards for mounting a lighting fixture support track system. Alternatively or supplementarily, the fixed profile can also preferably be formed by a longitudinal end face portion, for example, by its ribs. Therefore, the longitudinal end face portion of the profile portion not only serves to prevent falls but also acts as a load-bearing part of the supporting profile.

[0019] The retaining profiles preferably extend in a closed manner in the axial direction; that is, they preferably extend in a correspondingly closed manner along the longitudinal end face portion. This allows any luminaire support rail assembly to be mounted at any axial point of the retaining profile. It is also conceivable, in principle, that the retaining profiles be provided in an intermittent or otherwise multi-part manner in the axial direction. This can be advantageous, for example, for weight reduction or for locally increasing the flexibility of the retaining profiles.

[0020] The retaining profile is preferably designed to snap-fit ​​a luminaire support rail assembly that is at least partially inserted into the receiving space radially (i.e., radially about the longitudinal extension axis). Thus, the retaining profile is, for example, perpendicular to the longitudinal extension axis. This snap-fit ​​reception makes it possible to provide simple and stable retention for the corresponding luminaire support rail assembly. On the other hand, these retaining profiles also make it possible to provide equally simple and therefore particularly flexible fastening for any luminaire support rail assembly at every axial position.

[0021] The sidewalls are preferably parallel to each other. This preferably provides ample space within the receiving space to accommodate, for example, cables and electrical connection structures, and, where appropriate, electrical or electronic components. Alternatively, it is conceivable that the sidewalls are inclined toward each other in the direction of their longitudinal axis; for example, inclined toward each other from the receiving opening. This allows for the most compact connector possible. If the sidewalls are inclined apart from each other, for example, from the receiving opening, another storage space can be created within the receiving space; for example, for storing cables or other components.

[0022] The connector may preferably have multiple profile portions. In this way, the connector can be provided just as simply for mechanical connection with multiple support profiles.

[0023] Preferably, the profile portions originate from the common connection portion and extend axially toward their respective axial end faces about their respective longitudinal extension axes. In other words, all profile portions converge at the common connection portion, resulting in a compact overall connector construction while providing stable connection points for all profile portions. This also provides a simple transition between the various accommodating spaces, facilitating, for example, the laying of closely adjacent cables.

[0024] The profile sections preferably have the same cross-section. This allows for the provision of a luminaire support track system that is as uniform as possible. Specifically, it enables the inclusion of support profiles with the same cross-section in all profile sections. In this way, the number of components in the luminaire support track system can be kept as low as possible.

[0025] The profile portion is preferably arranged such that the connector has an L-shape, T-shape, X-shape, star shape, or other arbitrary shape. In this way, any branch of the luminaire support track system can be provided via a connector with a simple construction.

[0026] The longitudinal extension axes of all profile sections preferably extend in a single plane. This allows for the provision of connectors that make it easy to construct the luminaire support track system correspondingly within a single plane.

[0027] The connector may preferably have at least one through-hole, or one for each profile section, for the cable of the luminaire support track system to pass through. The through-hole is preferably located on one or more connecting walls. In this way, cables (e.g., for input or output power) can be introduced into the luminaire support track system via the connector in a simple manner. This significantly simplifies the complex electrical connection methods of conventional connectors.

[0028] A sheath can preferably be provided in the through opening for the cable to pass through. This allows for the safe and easy guidance of the cable through the through opening, thus providing cable routing. Furthermore, the sheath makes it possible to construct the cable entry as sealed; this is, for example, to provide a lighting support track system using connectors that meets the specified IP protection rating.

[0029] The connector may preferably have a mounting portion, such as a coupling opening for securing a cable suspension device or a snap-fit ​​portion of a non-standard connecting wall, for mounting a luminaire support track system equipped with the connector. In this way, the connector can provide a corresponding area for mounting the luminaire support track system. This allows, for example, the corresponding mounting portion to be omitted on the support profile side, or the connector to replicate the corresponding function of the support profile, thereby increasing installation possibilities.

[0030] According to another aspect of the invention, the invention also relates to a luminaire support track system having at least one connector from the connectors described above according to the invention. Furthermore, the luminaire support track system also has at least one elongated support profile extending along a longitudinally extending axis with a defined cross-section, and defining a receiving space. The cross-section of the support profile here has a profile substantially the same as the cross-section of the profile portion.

[0031] The support profile can be arranged such that at least the insert portion passes through the open axial end face in the axial direction so that the support profile is at least partially received in the receiving space of the profile portion in a supporting manner in the area between the end face and the retaining profile, such that the longitudinal extension axes of the profile portion and the support profile received therein are parallel to each other.

[0032] Therefore, the advantages of the connector can be correspondingly transferred to the entire luminaire support track system, as explained above. Since the support profile and the profile portion have essentially the same profile, the profile of the support profile can be continued in an aesthetically pleasing and functionally equivalent manner within the connector area. Furthermore, this allows the support profile to be accommodated in the connector in an efficient and preferably radially form-fit manner. Similarly, this makes it easily possible for the support profile to be accommodated in a telescoping manner within the profile portion, thereby enabling a simple connection even with variable insertion lengths.

[0033] The outer wall of the support profile can preferably be at least partially planar against the inner wall of the profile portion. This allows the support profile to be securely housed within the connector. Preferably, the outer wall of the support profile can be at least partially or completely planar against the inner wall of the profile portion, such that the support profile can be radially shaped-fitted and housed in a receiving space about its entire longitudinal axis. This almost completely planar contact allows for particularly high fitting precision, resulting in particularly stable component connections. Furthermore, the connector can thus be securely coupled to the support profile for purposes such as heat dissipation or as a grounding contact.

[0034] The support profile can preferably be inserted axially into the profile portion via an open axial end face, and preferably can be inserted telescopically. This allows for a particularly simple telescopic connection of the support profile into the connector or its profile portion, thereby enabling the length of the luminaire support track system to be variably set accordingly. Alternatively, it is also conceivable that the support profile can be inserted or snapped into the receiving space of the profile portion from below, for example, through a receiving opening.

[0035] The axial end edge of the profile facing the end face can preferably be used as an axial stop for the facing end edge of the support profile housed in the connector. In this way, a defined and / or maximized mounting position of the support profile in the connector can be provided.

[0036] The support profile preferably restricts an elongated receiving opening, preferably for at least partially receiving or inserting a corresponding luminaire support rail assembly. When the support profile and connector are connected, the receiving opening of the support profile preferably coincides with the receiving opening of the connector in the region of the insertion portion received in the support profile. These two receiving openings can also be directly aligned front and back in this region; the receiving opening of the support profile is further inward relative to the receiving space A. The receiving openings preferably extend in a plane, wherein these planes are more preferably parallel to each other. Thus, the interconnecting components of the luminaire support rail system, namely the support profile and the profile portion, provide a common receiving opening or two directly aligned receiving openings, which, or these receiving openings, along their entire length (i.e., including the connector and the support profile), allow for flexible arrangement or reception of the luminaire support rail assembly.

[0037] The support profile preferably has an additional retaining profile for supportingly holding the luminaire support track assembly, which is at least partially inserted into the receiving space of the support profile. Thus, the support profile also extends along its elongated portion for flexibly accommodating the luminaire support track assembly. The retaining profiles of the support profile can also each extend axially closed along the support profile, and are further preferably designed to snap-fit ​​the corresponding luminaire support track assembly.

[0038] With the support profile and connector in the connected state, these additional retaining profiles can preferably each continue axially from one of the retaining profiles of the relevant profile portion, or at least be aligned with one of the retaining profiles of the relevant profile portion when viewed in the direction of the respective longitudinal extension axis. In other words, the connector thus mimics the retaining profile of the support profile through its retaining profile. Because they are aligned with each other, the luminaire support rail assembly can be held arbitrarily at the connector, at the support profile, or at its respective retaining profile when extending across both, without loss of force, and is preferably received in a snap-fit ​​manner.

[0039] If the luminaire support track system has the connector with multiple profile sections as described above, and the luminaire support track system has multiple support profiles, then one support profile can be correspondingly accommodated in a supporting manner in one or more of the profile sections. In this way, luminaire support track systems that can be connected in series or branched can be provided.

[0040] The luminaire support track system preferably further includes at least one luminaire support track assembly capable of being secured to a retaining profile and / or another retaining profile; preferably in a detachable manner and / or by means of a snap-fit. Therefore, the luminaire support track system can be assembled or equipped with corresponding luminaire support track assemblies in any manner.

[0041] The luminaire support track assembly preferably includes electrical components, electronic components, or a cover plate. If the luminaire support track system has multiple luminaire support track assemblies, these assemblies may be identical or at least partially different. Corresponding electrical or electronic components may include, for example, lamps, sensors, speakers, etc. Luminaires may include, for example, strip lights, spotlights, emergency exit signs, etc.

[0042] The luminaire support track system may preferably also include a busbar element that extends within at least one receiving space or across two receiving spaces of the support profile and associated profile portion, so as to be preferably electrically connectable to or connected to the fixed electrical or electronic components. With the aid of the corresponding busbar element, an electrical connection can be established in a particularly simple manner. That is, the luminaire support track assembly may, for example, have a rotatable electrical connection element that extends into the corresponding receiving space when the luminaire support track assembly is mechanically supported. With this arrangement, the radially protruding connecting portion of the connecting element can then be driven to physical contact with the busbar element, thereby establishing electrical contact, by a corresponding rotational movement of the connecting element about a rotation axis pointing into the receiving space.

[0062] The accompanying drawings illustrate different views and embodiments of the connector 1 according to the invention and a lamp support track system 100 equipped with such connector 1. The connector 1 according to the invention is described first below.

[0063] The connector 1 according to the invention serves as a connector 1 for the elongated support profile 10 of the lamp support track system 100.

[0064] Connector 1 has an elongated profile portion 2, as shown in all the figures. Profile portion 2 extends along a longitudinal axis X, as exemplified by... Figures 1 to 7 As shown in the diagram. Specifically, profile portion 2 extends along the longitudinal extension axis X with a defined cross-section Q, as is particularly evident in... Figure 2 and Figure 5 As can be seen from the figures. It can also be seen from these figures that the cross section Q is defined, that is, it remains unchanged along the longitudinal axis X (i.e., its shape and size remain unchanged or constant).

[0065] Profile portion 2 preferably restricts the accommodating space A, such as from, for example, from Figures 1 to 7 As you can see. This space is used to accommodate the support profile 10.

[0066] Cross section Q has two side legs 3 and 4 arranged on both sides of the longitudinal extension axis X (see Figure 2 and Figure 5), to form two sidewalls 30, 40 opposite each other about the longitudinally extending axis X (see example) Figure 1 , Figure 3 , Figure 4 , Figure 6 and Figure 7 ).

[0067] The sidewalls 30 and 40 are preferably parallel to each other, as particularly from Figure 2 and Figure 5 As seen. Alternatively, it is conceivable that the sidewalls 30, 40, viewed in the direction of the longitudinally extending axis X (i.e., for example towards...) Figure 2 and Figure 5 (From the drawing plane) they are tilted towards each other.

[0068] Sidewalls 30 and 40 each have longitudinal end face portions 31 and 41 extending longitudinally along the longitudinal extension axis X, which together limit the receiving opening 5 of the receiving space A (see, for example, [reference needed]). Figures 1 to 4 The longitudinal end face portions 31 and 41 are formed at the distal edge regions of their respective sidewalls 30 and 40.

[0069] Cross section Q also has a connecting leg 6 that connects side legs 3 and 4 (see...) Figure 2 and Figure 5 ), to form connecting wall 60 (see, for example, see Figure 1 , Figure 3 , Figure 4 and Figure 7 The connecting wall 60 here at least partially or (substantially) completely restricts the receiving space A on the side of the side walls 30, 40 opposite to the receiving opening 5, as shown in the perspective top view. Figure 4 and Figure 7 As you can see.

[0070] Connector 1 may also have a mounting portion 62 for mounting a luminaire support track system 100 equipped with connector 1. The mounting portion 62 may, for example, be designed as a coupling opening 62 for securing a cable suspension device (not shown) (see [link]). Figure 4 The mounting portion 62 can also be formed by the snap-fit ​​portion 66 of the irregularly designed connecting wall 60 (see [reference]). Figure 4 ).

[0071] Profile portion 2 also has retaining profiles 7, each extending toward each other from two adjacent longitudinal end face portions 31, 41, and preferably extending into receiving space A, as particularly from Figures 1 to 3 and Figure 5 As can be seen, in order to be held in a supported manner and preferably received in a snap-fit ​​manner in a radial direction about the longitudinally extending axis X, at least partially inserted into the receiving space A, such as in Figure 6 and Figure 7 As illustrated in the example.

[0072] The contour 7 can preferably extend axially (preferably along the relevant longitudinal end face portions 31, 41), as if, for example, from Figure 1 and Figure 3 As you can see.

[0073] The profile 7 is spaced apart from the axial end face 8 of the profile portion 2 in the axial direction (i.e., with respect to the longitudinal extension axis X) (see Figure 1 The axial end face is open to allow the elongated support profile 10 of the luminaire support track system 100 to pass through, thereby ensuring that the cross section Q of the profile portion 2 is unobstructed between the longitudinal end face portions, particularly within the receiving space A, in the region between the end face 8 and the retaining profile 7, as it is particularly from... Figure 1 and Figure 2 I learned this from [the source].

[0074] In the region between end face 8 and retaining profile 7, longitudinal end face portions 31, 41 may preferably be formed as ribs 32, 42 extending partially into the receiving opening 5 in front of the receiving space A, these ribs preferably having longitudinal end edges 33, 43 pointing towards each other, such as in, for example in Figure 2 and Figure 5 As shown in the diagram. The longitudinal end edges 31, 41 can be provided here, for example, as slightly curved portions. These curved portions extend here as ribs 32, 42 in the receiving opening 5, but generally do not extend into the receiving space A. Thus, this region of the bent longitudinal end face portions 31, 41 serves, for example, as a clamping element to clamp the support profile 10 received in the profile portion 2 from below and, for example, in Figure 2 and Figure 5 The shapes drawn in the plane are appropriately enclosed.

[0075] The profile portion 2 can preferably be designed in such an irregular shape that the profile element 2 has a fixed profile 20 to radially support the support profile 10 to be housed therein. Here, the fixed profile 20 can be formed, for example, by an irregularly shaped connecting wall 60 and / or by longitudinal end face portions 31, 41 or their respective ribs 32, 42. Thus, the desired shape fit can be provided by these fixed profiles (20), preferably in... Figure 2 and Figure 5 The direction of the drawing plane.

[0076] As can also be seen from all the accompanying drawings, connector 1 may also have multiple profile portions 2. Figures 1 to 8 , Figure 11 , Figure 12 and Figure 14 In one embodiment, the connector 1 has two profile portions 2, which are arranged such that the connector 1 has an L-shape.

[0077] according to Figure 9 , Figure 13 and Figure 15 Each of the connectors in the embodiments has three profile portions 2, wherein according to Figure 9 and Figure 15 In this embodiment, the profile portion 2 is arranged such that the connector 1 has a T-shape. Figure 13 The profile portion 2 of the connector is arranged such that the connector 1 here has, for example, a star shape.

[0078] according to Figure 10 and Figure 16 The connector 1 in one embodiment has, for example, four profile portions 2, which are arranged such that the connector 1 has an X-shape.

[0079] Any other number, arrangement, or extension of the profile portion 2 is also conceivable. Particularly preferably, or particularly preferably all of the longitudinal extension axes X of the profile portions 2 extend in the same plane (e.g., in...). Figures 8 to 18 (within the corresponding drawing plane).

[0080] Profile portion 2 originates from common connection portion 9 and extends axially toward its respective axial end face 8 about its respective longitudinal extension axis X, as can be seen from all the figures.

[0081] Profile portion 2 can preferably all have the same cross-section Q; that is, they are identical in shape and size. This is essentially shown in all the figures.

[0082] Connector 1 may preferably have at least one or one through opening 63 for the cable (not shown) of the luminaire support track system 100 to pass through, such as from... Figure 4 As can be seen in the diagram. Here, a sheath 64 for the cable to pass through can preferably be provided in the through opening 63, as it is in... Figure 4 As exemplified by the dashed line in the middle.

[0083] The following is for reference. Figures 3 to 7 as well as Figures 14 to 18 A luminaire support track system 100 according to the invention is described. In addition to at least one connector in the connector 1 according to the invention, the luminaire support track system also has at least one elongated support profile 10 that extends along a longitudinally extending axis with a defined cross-section C and restricts a receiving space R. This is particularly evident from... Figures 3 to 5 As shown in the diagram.

[0084] The cross section C of the supporting profile 10 here has a profile substantially the same as the cross section Q of the profile portion 2, as it is specifically derived from... Figure 5 As can be seen in the diagram.

[0085] Similar to profile section 2, the cross section C of the supporting profile 10 preferably also has two side legs 13, 14 arranged on both sides of the longitudinal extension axis L to form two sidewalls 130, 140 opposite to the longitudinal extension axis L. Each of these sidewalls has a longitudinal end face portion 131, 141 extending longitudinally along the longitudinal extension axis L, which together restrict the receiving opening 15 of the receiving space R. Preferably, in this case, the cross section C also has a connecting leg 16 connecting the two side legs 13, 14 to form a connecting wall 160. Here, the connecting leg 16 at least partially or completely restricts the receiving space R on the side of the sidewalls 130, 140 opposite to the receiving opening 15, as shown in the figure. See in particular for details. Figures 3 to 7 .

[0086] The support profile 10 can be arranged as (or according to) Figures 3 to 7 The arrangement is as follows: at least the insertion portion 11 passes axially through the open axial end face 8 so that, in the region between the end face 8 and the retaining profile 7, the support profile 10 is at least partially received in the receiving space A of the profile portion 2 in a supportive manner. Preferably, the longitudinal extension axes X and L of the profile portion 2 and the support profile 10 received therein are parallel to each other (see, for example, [reference needed]). Figures 3 to 5 ). For example, specifically from Figures 3 to 7 As can be seen from the illustration, the connector thus essentially mimics the shape of the support profile 10, thereby allowing for a further aesthetic and at least partially functional continuation of the support profile 10 housed therein.

[0087] The outer wall 12 of the supporting profile preferably at least partially abuts against the inner wall 22 of the profile portion 2, such as from, for example, from Figure 5 As can be seen. Preferably, the support profile 10 is shaped to fit radially around its entire longitudinal axis L in a supporting manner, or herein Figure 5 It is contained within the containing space A. Figure 5 Therefore, the fitting accuracy between the supporting profile 10 and the profile portion 2 should preferably be selected in such a way that... Figure 5 Within the drawing plane, there are almost no or preferably no gaps between the parts in order to establish a particularly stable connection. In this way, a particularly high degree of imitation of the support profile 10 can also be achieved by the connector 1 or its profile portion 2.

[0088] If necessary, the connection between the support profile 10 and the connector 1 or profile portion 2 can be additionally secured; for example, by additional securing means such as screws or crimping. Alternatively, it is conceivable that... Figure 4 The visible embossing 67 allows for the creation of a force-fit or shape-fit connection between the connector 1 and the support profile 10.

[0089] For example from Figure 3 And also from Figures 14 to 17 As schematically seen, the support profile 10 can be axially (telescopically) inserted into the profile portion 2 via the open axial end face 8. In this way, the connector 1 and the support profile 10 can be variably and preferably telescopically connected to each other. In this manner, the specific variable length of the luminaire support track system 100 can be set by the insertion depth.

[0090] In principle, it is also conceivable that the support profile 10 can be inserted radially into the receiving space A and the profile portion 2 can be snapped in there; for example, by using longitudinal end face portions 31, 41 designed as clamping elements, which preferably function as snaps together with the sidewalls 30, 40.

[0091] As previously described, the support profile 10 may preferably restrict an elongated receiving opening 15, which, when the support profile 10 and connector 1 are connected, preferably coincides with the receiving opening 5 of connector 1 in the region of the insertion portion 11 received in the support profile 10, or these receiving openings may be arranged directly in a front-to-back arrangement or aligned with each other, as particularly from Figure 3 and Figure 5 As you can see.

[0092] For example, specifically from Figure 3 As can be seen, the end edge 70 of the profile 7 facing the end face 8 can act as an axial stop for the support profile 10 housed in the connector 1 or its profile portion 2.

[0093] The support profile 10 may preferably have an additional retaining profile 17 for supporting the luminaire support track assembly 110, which is at least partially inserted into the receiving space R of the support profile, such as from... Figure 3 and Figure 5 As you can see.

[0094] With the support profile 10 and connector 1 in the connected state, these additional retaining profiles 17 preferably each axially continue one of the retaining profiles 7 of the associated profile portion 2, as particularly from Figure 3 and Figure 5As can be seen, when the support profile 10 and connector 1 are in the connected state, these additional retaining profiles 17 are preferably aligned, in the directions of the respective longitudinal extension axes X and L, with one of the retaining profiles 7 of the relevant profile portion 2, such as from, for example, from Figure 3 and Figure 5 As you can see in the combined view.

[0095] If the connector 1 (as shown in all embodiments) has multiple profile portions 2, and the lamp support track system 100 equipped with the connector has correspondingly multiple support profiles 10, then the multiple (see Figure 3 and Figure 4 ) or all profile parts (see Figure 6 , Figure 7 and Figures 14 to 18 Each of the sections can be supported to accommodate one supporting profile 10.

[0096] refer to Figure 6 and Figure 7 The luminaire support track system 100 may also have at least one luminaire support track assembly 110, which can be fixed or secured to retaining profile 7 and / or additional retaining profile 17 (in this case, both); preferably in a detachable and / or snap-fit ​​manner.

[0097] The luminaire support track assembly 110 may include electrical or electronic components or a cover. In the embodiment shown in the figures, a support for a strip light is exemplarily illustrated for such a luminaire support track assembly 110.

[0098] The lighting support track system 100 may preferably also have a busbar element that extends or crosses the two receiving spaces A and R of the support profile 10 and the corresponding profile portion 2, so as to be electrically connectable or interfacing with the fixed electrical or electronic components.

[0099] The present invention is not limited to the above embodiments, as long as it is included in the subject matter of the following claims.
