DETAILED DESCRIPTION

[0051] The figures show different exemplary embodiments of a lighting strip system 1 according to the present invention. The lighting strip system 1 extends along a longitudinal axis direction L. The latter preferably extends rectilinearly. The lighting strip system 1 according to all the exemplary embodiments has a plurality of components. Thus, the lighting strip system 1 has an elongated carrier profile 2 with two elongated side walls 21, 22 that face each other and an elongated base wall 20 connecting the side walls 21, 22. The side walls 21, 22 and the base wall 20 together delimit a receiving space A. The carrier profile 2 preferably has an essentially U-shaped cross-section as viewed in the longitudinal axis direction L, as can be seen in FIGS. 7, 20 and 21. The base wall 20 and the two side walls 21, 22 of the carrier profile 2 preferably form the essentially U-shaped cross-section as viewed in the longitudinal axis direction L. The open side 23 of the carrier profile 2 opposite the base wall 20 preferably forms a light emission side. The receiving space A is also accessible via this open side 23 so that the latter also serves as a mounting opening for mounting all components of the lighting strip system in the receiving space of the carrier profile 2, as described below. The carrier profile 2 can be provided, for example, as a continuous casting part/extruded part, or as a bent part or a stamped bent part starting from a metal sheet or, according to the particularly preferred embodiment in accordance with FIGS. 7, 20 and 21, as a profile produced in a profiling installation. Other embodiments and materials are of course also conceivable. It is also conceivable for the carrier profile 2 to be formed in several parts in the longitudinal axis direction L, in order to thus be able to provide a carrier profile of any desired length.

[0052] As can be seen in particular in FIGS. 7, 20 and 21, the lighting strip system 1 further has a first coupling region 3 and a second coupling region 4. According to the first aspect of the invention, first coupling region 3 is provided, as viewed in the longitudinal axis direction L, cf. thus FIG. 7, between base wall 20 and second coupling region 4. In other words, the first coupling region 3 is arranged behind the second coupling region 4 with a view into the receiving space A through the open side 23, that is to say in the insertion direction E of the components of the lighting strip system 1 described below, that is to say with a view to the base wall 20. Thus, two coupling planes offset relative to each other in the insertion direction E are provided in the insertion direction E or as seen radially. According to the second aspect of the invention, as viewed in the longitudinal axis direction L, the first coupling region 3 is provided on the side of one of the side walls 21 and the second coupling region 4 is provided on the side of the other of the side walls 22, as depicted, for example, in FIGS. 20 and 21.

[0053] The first and/or second coupling regions 3, 4 can extend in the longitudinal axis direction L in the receiving space A and, as also shown in the depicted exemplary embodiments, preferably extend over the entire length of the carrier profile 2. The coupling regions 3, 4 can be provided in this case on at least one or, as depicted in the exemplary embodiments, preferably on both side walls 21, 22. In this case, the coupling regions 3, 4 can preferably be formed integrally with the side walls 21, 22. In the exemplary embodiments depicted, this is achieved by a corresponding profiling of the carrier profile 2 so that, as can be seen in FIG. 7, said carrier profile forms, for example, a sawtooth-like structure. The two sawtooth structures form the corresponding mechanical coupling regions 3, 4, which are described in more detail below. The sawtooth structure is achieved here by corresponding bending of the sheet metal carrier profile 2. It is also conceivable for the coupling regions 3, 4 to be provided separately.

[0054] In a further preferred embodiment, not depicted in the exemplary embodiments, it is also conceivable for the first mechanical coupling region 3 to have a plurality of coupling regions in planes spaced apart with respect to the base wall 20. Three and more coupling planes provided offset relative to one another in the insertion direction can thus also be provided.

[0055] The lighting strip system 1 additionally has an elongated power supply unit 5 which extends in the receiving space A in the longitudinal axis direction L. The power supply unit 5 can be provided between the base wall 20 and the first coupling region 3 and preferably on the base wall 20; for example as a busbar, as depicted in FIG. 7. However, it is also conceivable for the power supply unit 5 to be provided on at least one or both side walls 21, 22 as schematically depicted in FIGS. 20 and 21. In this case, the power supply unit 5 can be designed, for example, as a so-called busbar for rotary tapping, as already described above and depicted schematically in FIGS. 20 and 21 by way of example.

[0056] The lighting strip system 1 additionally has a lighting strip lamp 6, which extends in the longitudinal axis direction L. The elongated lighting strip lamp 6 is electrically contacted (this is of course releasable) with the power supply unit 5 and also releasably mechanically coupled to the second coupling region 4 (first aspect) or to both laterally opposite coupling regions 3, 4 (second aspect). The lighting strip lamp 6 preferably has any desired lamp components. These include in particular lighting means 60, such as an LED module with a printed circuit board 61 and LEDs or LED chips 62 arranged thereon, as can be seen by way of example in the cross-sectional view of FIG. 7. These lighting means 60 serve to emit light from the lighting strip system 1. Preferably, the lamp components further have an optical unit 63 for influencing the light emitted by the lighting means 60. The lighting strip lamp can further preferably have a lighting strip carrier 64 which carries the lamp components. This lighting strip carrier 64 can preferably be provided as a profiled metal sheet but also as a continuous casting part/extruded part or bent part or stamped bent part.

[0057] The lighting strip lamp 6 is preferably designed to be essentially planar on its outer side F facing away from the receiving space A and further preferably terminates essentially flush with the side 23 of the carrier profile 2 opposite the base wall 20. The lighting strip lamp 6 preferably extends between the two side walls 21, 22. Preferably, it extends completely between the two side walls 21, 22 in order to thus span the entire open side 23 transversely and to create a closed light emission space or a closed light emission side and consequently to produce a harmonious light line appearance. As can be seen in particular from FIGS. 7, 20 and 21, the lighting strip lamp 6 delimits in this case the carrier profile 2 preferably on the side 23 opposite the base wall 20 and preferably covers it essentially completely.

[0058] The lighting strip lamp 6 can have electronic components, such as an operating device 65, on its side R facing the receiving space A. Such electronic components 65 are preferably provided spaced apart from the opposite end faces 68 of the lighting strip lamp 6 in the longitudinal axis direction L and are particularly preferably provided at the center of the lighting strip lamp 6. Thus, in the region of the end faces 68 of the lighting strip lamp 6, a large free space is obtained in the receiving space A.

[0059] The lighting strip system 1 additionally has an electrical or electronic unit (also called a unit within the scope of the invention) 7. This unit 7 can be any form of electrical or electronic unit 7. Examples mentioned here are lamps, such as spotlights 72 (compare FIGS. 11 to 22) or an emergency light, sensors 70 (cf. FIGS. 1 to 7), such as a PIR sensor 715, AC/DC converters 71 (cf. FIGS. 8 to 10), camera modules, such as a security camera module 711, WLAN modules 713, scanners, projectors, laser projectors, monitoring electronics 70, 711, 715, data transmission systems 713, plug adapters 71 for connecting electrical or electronic components 711, 713, 715 (cf. FIGS. 8 to 10). However, the unit 7 is not limited to the foregoing examples and can comprise any form of electrical or electronic units.

[0060] The unit 7 has a functional region 73 and an operating region 74. The functional region 73 can have functional components of the electrical or electronic unit 7. Lamp or spotlight heads 720, preferably with a spotlight shaft 721, a sensor head 700, 715, connection sockets 710, 712, 714, such as USB-C sockets, WLAN antennas 713, camera heads 711 and the like are mentioned here purely by way of example. The operating region 74 can preferably have operating components of the electrical or electronic unit 7. Operating devices 740, a lamp controller, a sensor processing unit, an AC/DC converter unit and the like are mentioned here purely by way of example. The unit 6 or the operating region 74 can have a unit carrier 75, for example a carrier plate, on which at least a part of the components of the unit 6, preferably all components of the operating region 74 and further preferably of the functional region 73, are arranged.

[0061] In particular, the unit 7 depicted in FIGS. 8 to 10 in the embodiment of a USB adapter 71 offers innumerable possibilities of use via its standardized connection sockets 710, 712, 714; and this essentially without impairing the light line since only the connection socket region (functional region 73) is provided in a manner exposed to the outside, while the operating region 74 extends in the receiving space A behind the lighting strip lamp 6. The USB adapter 71 provides both a mechanical and an electrical connection possibility. It also serves as a data interface. It enables access to cable-connected (wired) or cable-less (wireless) data networks, depending on the underlying system. It can also use components such as WLAN-enabled drivers. If such an adapter 71 has a network-enabled driver with a LAN connector output, LAN sockets can also be integrated into the connection socket region (functional region 73) in addition to the USB sockets 710, 712, 714 shown here. This system thus effectively serves as an innovation platform for a plurality of technical developments, which can then easily be connected to the adapter 71. FIGS. 8 to 10 show, by way of example, a PID sensor module 715, a security camera module 711 and a WLAN stick or WLAN module 713.

[0062] The functional region 73 is arranged adjacent to the lighting strip lamp 6 in the longitudinal axis direction L. For this purpose, the functional region 73 preferably extends between the two side walls 21, 22; similarly to the lighting strip lamp 6. This can be clearly seen in FIG. 1, for example. There, the functional region 73 preferably extends here completely between the two side walls 21, 22. The functional region 73 preferably lies flush with and particularly preferably gap-free against the lighting strip lamp 6 in the longitudinal axis direction L, as can be seen in particular in FIGS. 1, 8, 11, 18b and 18c. In this way, it can be enabled to delimit or even cover the carrier profile 2 on the side 23 opposite the base wall 20 preferably in a gap-free manner and thus to close the lighting strip system 1 on its open side 23, in order to thus be able to produce an overall harmonious light line appearance on the light emission side.

[0063] The functional region 73 can be provided with respect to the longitudinal axis direction L in a region of one of the end faces of the operating region 74 opposite in the longitudinal axis direction L, preferably on one of the end faces (that is to say at the edge), as depicted by way of example in FIGS. 1 to 16. Consequently, the operating region 74 extends on one side away from the functional region 73. Alternatively, it is also conceivable for the functional region 73 to be provided spaced apart from both end faces of the operating region 74, as depicted, for example, in FIGS. 17 to 22. In a particularly preferred embodiment, the functional region 73 can also be provided to be movable relative to the operating region 74 in the longitudinal axis direction L.

[0064] The operating region 74 extends starting from the functional region 73 at least partially between the lighting strip lamp 6 and the base wall 20. In this way, a free space in the receiving space A between the lighting strip lamp 6 and the base wall 20 can be effectively utilized. The operating region 74 is in this case (releasably) electrically contacted with the power supply unit 5 and, when the first coupling region 3 is arranged between the base wall 20 and the second coupling section 4 as viewed in the longitudinal axis direction L, is releasably mechanically coupled to the first coupling region 3 (see FIGS. 1 to 12) or, when the coupling regions 3, 4 are arranged on the opposite sides of the side walls 21, 22 that face each other, to the coupling regions 3, 4 (see FIGS. 13 to 22).

[0065] The first and/or the second coupling region 3, 4 can be formed by profile regions, such as a latching profile, of the side walls 21, 22 (cf. FIGS. 1 to 22) or else of the power supply unit 5 (cf. FIGS. 13 to 22). It is also conceivable for the first and/or the second coupling region 3, 4 to be formed by recesses, such as punches, in the side walls 21, 22 or in the power supply unit 5. In other words, it is also conceivable for the first and/or the second coupling region 3, 4 to be provided on the power supply unit 5 and preferably also to be formed integrally with it. The latter is conceivable in particular when, for example, the power supply unit 5 is provided in the form of a busbar and the profiling, for example of the side walls 21, 22 or of the power supply unit 5 (as depicted schematically in FIGS. 20 and 21), forming the busbar thus likewise enables mechanical coupling.

[0066] In accordance with a preferred embodiment, the electrical or electronic unit 7 can have a first coupling element 76 corresponding to the first coupling region 3 (cf. FIGS. 1 to 22) and preferably further to the second coupling region 4 (cf. FIGS. 13 to 22) for mechanically coupling to the first coupling region 3 and preferably further to the second coupling region 4. Preferably, the operating region 74, preferably its unit carrier 75, carries the first coupling element 76. Similarly, the lighting strip lamp 6 can also have a second coupling element 66 corresponding to the second coupling region 4 (cf. FIGS. 1 to 22) and preferably further to the first coupling region 3 (cf. FIGS. 13 to 22) for mechanically coupling to the second coupling region 4 and preferably further to the first coupling region 3. The lighting strip carrier 64 can also preferably carry the second coupling element 66. As depicted in the exemplary embodiments in FIGS. 1 to 12, 17 and 22, the first and/or the second coupling element 66, 76 can have latching springs, pretensioned laterally to the respective coupling regions 3, 4, with a first latching section, preferably a V-shaped latching section 660, 760 projecting outward. The first latching section 660, 760 interacts in a latching manner with a corresponding second latching section 30, 40 of the respective coupling region 3, 4 in order to provide the mechanical coupling.

[0067] As can be seen in particular from FIGS. 5, 9, 12 to 14 and 17, the lighting strip lamp 6 can have a first electrical contacting element 67 and the unit 7, preferably the operating region 74, can have a second electrical contacting element 77. These serve for electrically contacting the lighting strip lamp 6 or the unit 7 preferably directly when the same is inserted into the receiving space A or when mechanically coupling the same to the respective mechanical coupling region 3, 4. The electrical contacting elements 67, 77 can be designed in cooperation with the power supply unit 5, with which they are to be electrically contacted, in such a way that, as shown in the figures, they establish a contact between the tapping agent and the conductors of the busbar (cf. in particular FIGS. 1 to 12). In accordance with further possibilities, they can, for example, enable rotary tapping when a busbar integrated into the side wall is formed (cf. FIGS. 13 to 22), but they can also be designed, for example, as an insulation-displacement tap (not depicted in the exemplary embodiments) or also as a socket system tap.

[0068] In a particularly preferred embodiment, the first and second electrical contacting elements 67, 77 can be constructed identically. Consequently, identical parts can be used in order to electrically contact different components with the same power supply unit 5 even in different mechanical coupling planes or coupling sides.

[0069] As depicted in the exemplary embodiments and as can be seen in particular in the lateral sectional views in FIGS. 2, 4, 6, 13, 20 and 22, the first electrical contacting element 67 can extend in a first extension direction in a region between the lighting strip lamp 6 and the base wall 20 (that is to say in an insertion direction E). In this case, the first electrical contacting element 67 preferably projects from the lighting strip lamp 6 into the receiving space A as far as the power supply unit 5. Thus, electrical contact with the power supply unit 5 is automatically provided when the lighting strip lamp 6 is completely mechanically coupled (optionally after rotation in the case of rotary tapping, as described below). The lighting strip carrier 64 can preferably carry the first electrical contacting element 67.

[0070] Similarly, the second electrical contacting element 77 can also extend in a second extension direction in a region between the lighting strip lamp 6 and the base wall 20 (that is to say in the insertion direction E). In this case, particularly when using identical parts, the second electrical contacting element 77 is provided in such a way that it extends in a protruding manner on both sides of the operating region 74 with respect to the previously named extension direction; thus penetrates the operating region 74. Alternatively, as can be seen from FIGS. 14 and 17, the second electrical contacting element 77, for example, can be provided raised toward the base wall 5 in order to thus be provided at the same height as the first electrical contacting element 67 with respect to the extension direction of such base wall. In this way, despite the use of identical parts, consideration can be given to a reduced distance of the operating region 74 from the power supply unit 5 in comparison with the distance of the lighting strip lamp 6 from the power supply unit 5. The use of contacting elements 67, 77 as identical parts can be clearly seen, for example, in FIGS. 6 and 14. Preferably, the operating region 74, preferably its unit carrier 75, carries the second electrical contacting element 77.

[0071] Alternatively or additionally, a rotary tap already described above is also conceivable, which serves for electrical coupling, mechanical coupling or electrical and mechanical coupling. For this purpose, the lighting strip lamp 6 and/or the electrical or electronic unit 7 can have one or more (for example at least two) rotary bodies 69, 79 rotatably provided about a rotational axis X with laterally protruding latching projections 690, 790 which, by rotating the rotary body 69, 79 about its rotational axis X, can be moved between a retracted mounting position (cf., for example, FIGS. 14, 17, 18a) for inserting the lighting strip lamp 6 or electrical or electronic unit 7 into the carrier profile 2 and an extended positions (not depicted; cf. FIG. 18c by way of example) for interacting with the coupling regions 3, 4 for mechanical coupling and/or the power supply unit 5 for electrical coupling. For this purpose, the latching projections preferably have the coupling elements 76, 66 and/or the electrical contacting elements 67, 77.

[0072] For example, the rotary bodies 69, 79 of the exemplary embodiment in FIGS. 13 to 16 can both provide both mechanical and electrical coupling; as a rule, at least one rotary body 69, 79 should enable electrical coupling and at least one, but preferably all, should enable mechanical coupling.

[0073] As a result of the edge-side arrangement of the functional region 73 with respect to the operating region 74, it is then conceivable, for example, to insert the unit 7 after the installation of a lighting strip lamp 6 and to couple it electrically and mechanically by means of a rotary tap. The operating region 74 which then extends away from the installed part of the lighting strip lamp 6 can then be covered toward the front by installing a further part of the lighting strip lamp 6. This in turn requires a comparatively long free end 600 of the part of the lighting strip lamp 6 covering the operating region 74. Since, in particular when providing the coupling by means of a rotary tap, the rotary body 69 has to be arranged in a manner offset in the longitudinal axis direction L next to the unit 7, in order to couple it to the coupling regions 3, 4 and power supply unit 5, the second coupling element 66 can also have a further latching means, like the latching springs described above, in addition to the corresponding latching projection 670, as also depicted in FIG. 17. In this way, the lighting strip lamp 6 preferably has the second coupling region 66 (or a part thereof) in the form of latching springs in the region between at least one of the end faces 68 and electronic component.

[0074] It is also conceivable, as can be seen, for example, from the exemplary embodiment in FIGS. 17 to 22, for the operating region 74 to extend from the functional region 73 on both sides with respect to the longitudinal axis direction L. Thus, a smaller overlap of unit 7 with the adjoining part of the lighting strip lamp 6 occurs. The components are then installed, for example, in such a way that first the unit 7 lying in the rear plane is installed and electrically and mechanically coupled by means of the rotary bodies 79, and then the adjoining parts of the lighting strip lamp 6 are installed in a manner connecting thereto.

[0075] It is also conceivable in all the exemplary embodiments for the coupling regions 3, 4 in conjunction with the respective coupling elements 66, 76 to preferably permit a sliding movement of the lighting strip lamp 6 or of the electrical or electronic unit 7 along the longitudinal axis direction L; thus enabling form closure transversely to the longitudinal axis direction L in order to hold the unit 7 in the carrier profile 2. For this purpose, the latching springs, for example, in accordance with the exemplary embodiments in FIGS. 1 to 12 and 22 can be designed accordingly. Moreover, for example, it is also possible, as shown in FIG. 17, to first install a part of the lighting strip lamp 6 and to couple it by means of a rotary tap. As shown in FIG. 18a, the unit 7 can then be inserted and first only mechanically coupled, here, for example, by means of the left rotary tap 79 (alternatively by means of the latching spring in accordance with FIG. 22). The unit 7 can then be displaced toward the installed part of the lighting strip lamp 6 until its functional region 73 bears against the lighting strip lamp 6. Then, in the position in accordance with FIG. 18b, the second rotary body 79 can also be actuated (i.e., rotated about the rotational axis X), in order to bring about an electrical and preferably also a fixed mechanical coupling via the latter. As shown in FIG. 18c, a further part of the lighting strip lamp 6 can then be installed so that it, with the other part of the lighting strip lamp 6, laterally encloses the functional region 73 opposite of the unit 7 and covers the part of the operating region 74 that was previously exposed to the outside. In particular in accordance with this embodiment, at least one of the rotary bodies 69, 79 can have no latching projections 690, 790 (67, 77) for electrical coupling, wherein the mechanical coupling 690, 790 (66, 76) preferably permits a sliding movement of the lighting strip lamp 6 or of the electrical or electronic unit 7 along the longitudinal axis direction L.

[0076] The rotary body 69, 79 can have a rotary manipulator 692, 792 for rotating the rotary body 69, 79 about its rotational axis X. The rotary manipulator 692, 792 can preferably extend away radially on one side (rotary manipulator 692) or on multiple sides, preferably on two sides (wing-like rotary manipulator 792). In this case, it can be arranged centrally or coaxially or symmetrically or asymmetrically as viewed with respect to the rotational axis X. While the wing-like design of the rotary manipulator 792 enables easy access thereto, the one-sided and lever-like design of the rotary manipulator 692 has the advantage that it leaves the downwardly directed emission region of the lighting strip lamp 6 free and thus does not impede the emission of light.

[0077] Thus, both the lighting strip lamp 6 and the unit 7 can be inserted into the carrier profile 2 preferably via the open side 23 for mechanical coupling with the respective coupling regions 3, 4 while, due to the coupling planes or coupling sides provided offset from one another, an overall significantly more compact design of the lighting strip system is enabled. Regions or components of the unit 7 which are not required for an outwardly exposed provision can be completely accommodated in the receiving space A. The installation space for the unit 7 which takes up the light line or the light emission side 23 is thus reduced overall so that overall in comparison with currently known solutions a clearly more harmonious and largely interruption-free and gap-free light line can be created.

[0078] In particular, the functional region 73 can thus also be designed to be essentially planar on its side S facing away from the receiving space A. This side S is particularly preferably essentially flush with the side 23 of the carrier profile 2 opposite the base wall 20 and further preferably terminates with the planar outer side F of the lighting strip lamp 6.

[0079] Like the carrier profile 2, the lighting strip lamp 6 can also be formed in several parts in the longitudinal axis direction L. In this case, at least some parts of the lighting strip lamp 6 that are adjacent to one another can preferably adjoin one another flush and preferably gap-free in the longitudinal axis direction L. A functional region 73 of an electrical or electronic unit 7 can be arranged at least between two parts of such a multipart lighting strip lamp 6, as already described above.

[0080] The end faces 68, 78, directed in the longitudinal axis direction L, of the lighting strip lamp 6 and the functional region 73 are preferably flat and particularly preferably oriented transversely to the longitudinal axis direction L.

[0081] The present invention is not limited to the number of adjacent carrier profiles 2, power supply units 5, lighting strip lamps 6, units 7, in particular functional regions 73, first and second coupling regions or coupling planes. The present invention is also not limited to a number or type of units 7. Any type of electrical or electronic unit 7 and any combination thereof within a lighting strip system 1 are conceivable. These can also all be placed directly next to one another, wherein then correspondingly preferably a plurality of the above-described first coupling regions are provided in different coupling planes. The present invention is also not limited to the type of electrical or mechanical coupling. The features of the present exemplary embodiments can be combined and exchanged in any way with and among one another, provided that they are encompassed by the subject matter of the following claims.
