Description

[0001] The present invention relates to a light rail system with a U-shaped, elongated receiving profile, which is designed to receive an elongated strip of light-emitting diodes, according to the preamble of claim 1.

[0002] Such a light rail system can have a receiving profile made of an aluminium material, wherein the receiving profile is U-shaped in a cross-sectional view with an interior or recess designed to receive the LED strip.

[0003] By arranging the LED strip within the mounting profile, the LED track lighting system is protected against environmental influences. This makes the LED track lighting system suitable for installation outdoors, such as in the exterior of buildings or in other locations, like industrial buildings.

[0004] The LED strip, which is held by the mounting profile, typically has an elongated, channel-shaped profile made of an elastomer material. This channel-shaped or base profile has a bottom wall with an underside and side walls extending laterally from the bottom wall, each with a top surface. Between the bottom wall and the side walls, there is an interior space or recess in which an elongated LED strip is arranged.

[0005] The LED strip has a preferably flexible conductor track and a plurality of LEDs arranged in the longitudinal direction of the LED strip, and contact means are also arranged in the inner recess of the base profile, which are provided for supplying the LEDs with electrical energy, wherein the inner recess is provided with a potting compound which protects the LED strip against contamination or moisture at the mounting location of the light rail system.

[0006] Based on DE 10 2023 001 288 B4, a light rail system for the reversible mounting of LED lighting has become known.

[0007] A strip of light-emitting diodes, which originates from the applicant, has become known through DE 20 2025 101 445.

[0008] The present invention is based on the objective of creating a light rail system with a light-emitting diode strip for mounting locations where mounting of the light rail system without the use of screws is desired and where difficult operating conditions for the light-emitting diode strip may prevail at the mounting locations.

[0009] The invention has the features specified in claim 1 to solve this problem; advantageous embodiments thereof are described in the further claims.

[0010] The invention provides a light rail system with a U-shaped, elongated receiving profile, which is designed to receive an elongated LED strip, wherein the LED strip has an elongated channel-shaped profile with a bottom wall having an underside and side walls extending laterally from the bottom wall, each having a top surface, and an inner recess formed between the bottom wall and the side walls, and has an elongated LED strip arranged in the inner recess, wherein the LED strip has a preferably flexible conductor track and a plurality of LEDs arranged longitudinally along the LED strip, and contact means are arranged in the inner recess which are designed to supply the LEDs with electrical energy, and the inner recess can be filled with potting compound, wherein the receiving profile has a first receiving chamber,which is designed to accommodate the LED strip, and the imaging profile has a second imaging chamber designed to accommodate a magnetooperative device.

[0011] The U-shaped, elongated mounting profile can be made of an aluminum alloy, which is positioned in the inner recess of the mounting profile to accommodate an elongated LED strip. Instead of aluminum, the mounting profile can also be made of other materials, such as another metallic material or a plastic material; this list is not exhaustive.

[0012] The mounting profile has a bottom wall from which opposing side walls extend, forming an interior space or recess designed to accommodate an elongated strip of LEDs.

[0013] The LED strip, in turn, has an elongated, channel-shaped profile or base profile, which is made, for example, of an elastic plastic material. It has a base wall with a bottom surface and side walls extending laterally from the base wall, each with a top surface. The base profile forms an interior space between the base wall and the side walls, in which an elongated LED strip and contact elements can be arranged. These contact elements supply electrical energy to the LEDs, which are arranged on the LED strip, for example, using COB technology.

[0014] The LED strip thus has an elongated, channel-shaped profile, also referred to as the base profile, which has a bottom wall with a base surface and side walls extending laterally from the bottom wall, each with a top surface. The base profile is formed in one piece and has a trough-shaped or channel-shaped cross-section, for example, a U-shaped configuration, and can be made, for example, of a thermoplastic elastomer (TPE), in particular a urethane-based thermoplastic elastomer (TPU), or, for example, of a polyvinyl chloride (PVC) material or a thermosetting material.

[0015] An internal recess is formed between the base wall and the side walls extending longitudinally along the base profile. An elongated LED strip is provided within this recess. The LED strip has a flexible conductor track and a plurality of LEDs arranged longitudinally along the conductor track. The internal recess also contains contact elements for supplying the LEDs with electrical power. The internal recess can be filled with a potting compound that covers the LED strip and is, for example, diffusely colored. The internal recess is designed to receive the potting compound.The light-emitting diodes are arranged on the conductor track using chip on board (COB) technology and are so close to each other that the user of the light-emitting diode strip according to the invention cannot perceive the individual light-emitting diodes as separate points of light, but perceives the illuminated light-emitting diode strip as a continuous light source.

[0016] It is also possible to use an IP00 or IP20 strip instead of the LED strip encased in potting compound in the inner recess of the base profile, so that the respective application and the required level of protection can be taken into account.

[0017] The LED strip of the light rail system according to the invention is arranged in a first receiving chamber of the receiving profile. In addition to the first receiving chamber, the receiving profile also has a second receiving chamber, which is designed to receive a magnetooperative device.

[0018] The magnetooperative device can, for example, be a strip-shaped permanent magnet, or a plurality of permanent magnets arranged at a distance from each other on a carrier strip, so that the carrier strip with the permanent magnets is received by the second receiving chamber.

[0019] The resulting light track system can be attached to a ferromagnetic mounting location without the need for screws. The mounting location can, for example, be a ferromagnetic metal strip to which the light track system can also be attached upside down. Thus, a metal strip, located, for example, on the ceiling of a hall or building, can be equipped with the light track system according to the invention. The light track system is then held on the metal strip by the magnetooperative device in the second receiving chamber of the elongated receiving profile and can be used to illuminate the building or hall.Due to the design of the light track system with the magnetooperative device, the light track system can also be used for temporary lighting of the building or hall, since the light track thus formed can be reversibly removed from the metal strip without the need for tools.

[0020] According to a further development of the invention, the second receiving chamber has, in a cross-sectional view, a first area with a first width extent and a second area with a second width extent, wherein the second width extent differs from the first width extent.

[0021] This creates a configuration in which the area of ​​the receiving chamber with the second width is designed to accommodate a strip-shaped magnetooperative device. The area with the first width, which is smaller than the second width, can serve as a receiving space in which cuboid permanent magnets can be inserted. These can be added, for example, to the strip-shaped permanent magnets to increase the magnetic holding force with which the light rail system can be fixed to a ferromagnetic counterbody.

[0022] According to a further development of the invention, the second area of ​​the second recording chamber is arranged in a vertical axis direction of the recording profile at a clear distance to the first recording chamber.

[0023] Thus, the aforementioned recording chamber has a height extension that largely extends from the upper surface of the second area of ​​the second recording chamber to the underside of the first recording chamber and is designed to accommodate, for example, the aforementioned cuboid permanent magnets.

[0024] According to a further development of the invention, the second receiving chamber adjoins the first receiving chamber in the vertical direction of the receiving profile, and the clear distance between a lower surface of the first receiving chamber and a top surface of the second receiving chamber, both arranged in the vertical direction of the receiving profile, is zero. Thus, viewed in the vertical direction of the receiving profile, the second receiving chamber is directly adjacent to the first receiving chamber.

[0025] The second recording chamber can contain the aforementioned permanent magnets, which have a height extension in the vertical axis direction of the recording profile that is slightly greater than the height extension of the second recording chamber.

[0026] This creates a configuration in which a magnetooperative device arranged in the second receiving chamber, in the form of the aforementioned permanent magnets, for example, is subjected to a predetermined pressure force by the LED strip located in the first receiving chamber and is thus securely held in the second receiving chamber, without the risk of unintentional displacement or relocation of the permanent magnets during the assembly of the light rail system at the mounting location in the longitudinal direction of the light rail system.

[0027] According to a further development of the invention, a magnetooperative device is arranged in the second receiving chamber and has an elongated, for example strip-shaped configuration and a top side which is at a clear distance from the bottom of the bottom wall of the channel-shaped profile of the light-emitting diode strip arranged in the first receiving chamber.

[0028] This configuration is advantageous, for example, when the strip-shaped permanent magnet located in the second mounting chamber already generates a sufficiently high magnetic holding force to securely hold the light rail system in a ferromagnetic mounting location. This configuration can be used, for instance, when the LED strip arranged in the mounting profile has such a small height and width that the combined mass of the LED strip and the elongated mounting profile of the light rail system is so low that the magnetic holding force achieved by the strip-shaped permanent magnet is sufficient to securely hold the light rail system in a ferromagnetic mounting location.

[0029] According to a further development of the invention, a magnetooperative device is arranged in the second receiving chamber and has an elongated configuration and a top surface which is arranged with overlap to the bottom surface of the bottom wall of the channel-shaped profile of the LED strip arranged in the first receiving chamber and the bottom wall is arranged to apply a pressure force to the top surface of the magnetooperative device.

[0030] This configuration allows for a compressive force to be exerted from the elastic base wall of the LED strip's channel profile onto the top of the cuboid permanent magnets, as explained above. This is achieved by arranging the upper surface of the cuboid permanent magnets in the second receiving chamber with an overlap with the underside of the base wall of the LED strip's channel-shaped profile. The cuboid permanent magnets in the second receiving chamber enable a remarkably high magnetic holding force, allowing even a track lighting system with a larger LED strip and thus a higher mass to be securely fixed to a metallic mounting surface without the need for screws.

[0031] According to a further development of the invention, it is also provided that an elongated mounting profile can be arranged in the second receiving chamber, which is designed to receive the ferromagnetic device.

[0032] This mounting profile can, for example, be a flexible extrusion profile which has a receiving area with side walls extending in the vertical axis direction of the second receiving chamber, which are designed to hold the magnetooperative device.

[0033] For this purpose, the side walls can be equipped with locking lugs, for example, which are elastically deformed when permanent magnets are inserted into the space between the side walls. This securely holds the permanent magnets between the side walls, allowing the mounting profile with the permanent magnets to be positioned in the second receiving chamber. The configuration can again be achieved such that, viewed in the vertical direction of the receiving profile, the permanent magnets are positioned with their upper surfaces overlapping the LED strip located in the first receiving chamber. This ensures that the underside of the base wall of the base profile exerts a compressive force on the permanent magnets, thus securely holding both the permanent magnets and the mounting profile in the second receiving chamber.

[0034] According to a further development of the invention, it is provided that the mounting profile has retaining segments extending away from the side walls, aligned to each other and extending in the longitudinal direction of the elongated receiving profile, in the form of positive locking segments or friction locking segments, which are designed to clamp the magnetooperative device between the retaining segments.

[0035] The retaining segments can be designed in the form of the locking lugs mentioned above, for example, and can have a circular segment-shaped cross-section. The permanent magnets are thus positioned between the opposing side walls of the mounting profile and securely held by the positive locking or friction locking segments formed on the side walls.

[0036] According to a further development of the invention, the light rail system is also supplemented by a ferromagnetic mounting element provided with double-sided adhesive tape, which is designed for attachment to a non-ferromagnetic surface. This allows the mounting element, for example, a metal strip with double-sided adhesive tape, to be fixed to a mounting location, which may be, for example, a non-metallic plastic profile. The metal strip thus serves as a counter-holder for the permanent magnets of the light rail system according to the invention, thereby enabling the light rail system to be securely fixed to a non-metallic counter-holder as well.

[0037] Finally, according to a further development of the invention, the mounting means are also designed in the form of ferromagnetic segments, which are arranged at intervals along a longitudinal direction of the adhesive tape. Thus, it is not necessary for the ferromagnetic elements of the mounting means to be, for example, in the form of a continuous metallic strip, but can be in the form of segments of a strip, each spaced apart from the others and attached to a double-sided adhesive tape. The mounting means provided with the ferromagnetic segments can then be attached to the aforementioned plastic strip, for example, using the double-sided adhesive tape, and the light rail system with the permanent magnets can then be attached to the mounting means.This means that the light rail system according to the invention can be used universally and can be fixed and securely held on both a ferromagnetic mounting surface and a non-ferromagnetic mounting surface without the need for screws or the like.

[0038] The invention will be explained in more detail below with reference to the drawings. These show: Fig. 1 a perspective view of a section of a light-emitting diode strip according to an embodiment of the light rail system according to the present invention; Fig. 2 a sectional view of the LED strip according to section II-II according to Fig. 1; Fig. 3 a cross-sectional view of a receiving profile of the light rail system according to an embodiment according to the present invention with a strip-shaped permanent magnet arranged in the second receiving chamber; Fig. 4 a representation similar to that shown in Fig. 3, which shows a second embodiment of the recording profile; Fig. 5 a cross-sectional view of the recording profile according to Fig. 5 with a magnetic body comprising a strip-shaped base body and a cuboid-shaped top body, wherein the magnetic body has a cylindrical hat-shaped configuration in a cross-sectional view; Fig. 6 a representation similar to that shown in Fig. 5, which is the second embodiment of the recording profile with the magnetic body according to Fig. 5 shows; Fig. 7 a representation similar to that according to Fig. 5, which shows a cuboid-shaped magnetic body arranged in an elongated mounting profile; Fig. 8 a representation similar to that shown in Fig. 7, which is the second embodiment of the recording profile with the magnetic body according to Fig. 7 shows; Fig. 9 a perspective view of the light rail system with the LED strip arranged in the mounting profile and the components arranged and schematically shown in the LED strip; Fig. 10 a schematic representation of an installation or assembly situation showing the light rail system arranged on a metallic surface; and Fig. 11 a representation similar to that according to Fig. Figure 10, which shows an installation or mounting situation in which the light rail system is arranged on a non-metallic surface.

[0039] Fig. Figure 1 of the drawing shows a schematic perspective representation of a light-emitting diode strip 1 with a base profile 4, a light-emitting diode strip 5 and potting compound 7 arranged in the base profile 4.

[0040] The light-emitting diode strip 1 has an elongated channel-shaped profile 8, which is designed as an elastically formed base profile 4, which has a channel-shaped interior 19 in which the light-emitting diode strip 5 is arranged, which has a plurality of light-emitting diodes 9 provided at a small distance from each other.

[0041] The LED strip 5 can be used based on Fig. 9 of the drawing shows the flexible conductor track 10 and the one in Fig. The nine LEDs shown schematically can be mounted on the circuit board 10 using chip-on-board (COB) technology. COB technology for arranging the LEDs on the circuit board is presented here only as one possible mounting method. Other techniques for arranging LEDs are also familiar to those skilled in the art, so COB technology should not be considered the only option.

[0042] The figures in the drawing show a schematic representation of a magnetooperative device 32, for example, in the form of a band or strip 34 designed as a permanent magnet 33, which is arranged in the second receiving chamber 35 of the receiving profile 36. This configuration has the advantage that a light rail system 37 equipped with the magnetooperative device 32 can be arranged on a support profile 38 in the form of, for example, a support rail or a support frame or the like, as shown by Fig. 10 and Fig. 11 of the drawing shows that no intervention in the structure of the support rail or support frame or support profile is necessary, as is the case, for example, when the support has to be provided with drill holes in order to attach fixtures for the arrangement and fixing of the light rail system to the support.

[0043] With the COB arrangement, it is possible to place the LEDs at such a small distance from each other that the LEDs produce a uniform light for the viewer, so that the viewer does not perceive individual points of light, but sees a continuous, single or one-piece LED strip with a homogeneous emission of light.

[0044] The basic profile 4 can be an elastic profile with a trough-shaped or channel-shaped cross-section, which is made, for example, of a thermoplastic elastomer (TPE), in particular a urethane-based thermoplastic elastomer (TPU), or also on the basis of a polyvinyl chloride (PVC) material or on the basis of an elastic thermosetting material.

[0045] The basic profile 4 of the LED strip 1, as shown by Fig. As can be seen in drawing 2, the illustrated embodiment has two side walls 11 which are formed integrally with the bottom wall 12 of the LED strip 1 and extend in the longitudinal direction “L” according to the double arrow. Fig. 1. The profile has a longitudinal rib 13 on both sides of the respective side wall, which on the one hand increases the stiffness of the base profile 4 and on the other hand increases the preload when the LED strip is arranged in the first receiving chamber 39 of the receiving profile 36. The longitudinal ribs 13, which are based on the embodiment according to Fig. As can be seen in Figure 9 of the drawing, the preload acting on the side walls 11 of the LED strip 1 increases when the LED strip 1 is arranged in the first receiving chamber 39 of the receiving profile 36.

[0046] As can be seen from the examples mentioned here, which are merely given as examples. Fig. 3 and Fig. As can be seen in Figure 4 of the drawing, the receiving profile 36 has a longitudinally extending rib 41 on each of its two side walls 40, directed towards the first receiving chamber 39. This rib increases the preload acting on the side walls 11 of the LED strip 1, so that the LED strip 1 is securely held or clamped in the first receiving chamber 39 of the receiving profile 36, even when, for example, Fig. 10 and Fig. 11 of the assembly configurations shown in the drawing, in which the receiving profile 36 with the respective underside or bottom wall 42 is mounted overhead on the support profile 38, cannot unintentionally detach from the first receiving chamber 39. Fig. Figure 10 of the drawing also shows that contact elements 2 are provided in the interior space 19 or the interior recess 19 of the profile 4, which are designed to supply the light-emitting diodes 9 with electrical energy. The contact elements can, for example, be copper traces running along the longitudinal direction L of the conductor track 10.

[0047] Predetermined markings may be provided on the bottom wall 12 of the LED strip 1, which represent cutting lines or positioning guidelines for the user, at which the user can cut or position the LED strip 1.

[0048] Fig. Figure 2 of the drawing also shows that the bottom wall 12 of the base profile 4 has a bottom surface 14 and the two side walls 11 of the base profile 4 each have an upper cover surface 15.

[0049] As can be seen from the perspective representation of the Fig. As can be seen in Figure 9 of the drawing, the receiving profile 36 has an overall U-shaped elongated configuration with the aforementioned bottom wall 42 and side walls 40 extending integrally from the bottom wall 42 and the aforementioned ribs 41, which exert a clamping force on the side walls 11 of the base profile 4 of the LED strip 1, as explained above.

[0050] Furthermore, the recording profile has 36, as can be seen from Fig. As can be seen in section 4 of the drawing, next to the first receiving chamber 39, in which the LED strip 1 can be received, as shown by Fig. As can be seen in drawing 9, a second receiving chamber 35 is designed to receive the magnetooperative device 32.

[0051] The second recording chamber 35 has, as can be seen from the cross-sectional view according to Fig. As can be seen in section 4 of the drawing, a second area 16 with a width extending in the direction of the double arrow B towards Fig. 4, which differs from the width extent of the first area 17, wherein the width extent of the second area 16 is greater than the width extent of the first area 17.

[0052] The second area 16 has on both sides of the center line 18 a respective area 20 extending in the vertical axis direction H, which is provided so that, on the one hand, the permanent magnet 33, designed as a strip 34, can be more easily moved along the longitudinal direction L ( Fig. 9) can be introduced into the second area 16 and, on the other hand, also based on Fig. 7 visible mounting profile 21 can be more easily inserted into the second area 16 of the second receiving chamber 35.

[0053] Both the permanent magnet 33, designed as a strip 34, and the mounting profile 21 are held by a clamping force acting on the top side 23 of the strip 33 and the mounting profile 21, respectively, via the area 22 of the second area 16, which tapers in the vertical axis direction H.

[0054] Fig. Figure 4 of the drawing shows that the second area 16 is arranged in the vertical axis direction H of the recording profile 36 at a clear distance A to the first recording chamber 39.

[0055] Fig. Figure 4 of the drawing also shows that the second receiving chamber 35, and in particular the first region 17 of the second receiving chamber 35, adjoins the first receiving chamber 39 in the vertical axis H of the receiving profile 36, and that the clear distance A between the underside 24 of the first receiving chamber 39, arranged in the vertical axis H of the receiving profile 36, and the upperside 25 of the first receiving chamber 39, or rather the first region 17 of the first receiving chamber 39, arranged in the vertical axis H, is zero. This clarifies that the second receiving chamber 35 adjoins the first receiving chamber 39 directly.

[0056] Fig. Figure 3 of the drawing shows, with reference to the dashed lines 26, the arrangement of the LED strip 1 in the first receiving chamber 39. The underside 14 of the bottom wall 12 of the base profile 4 is provided at a clear distance A to the top 23 of the cover surface 27 of the permanent magnet 33, which is designed as a strip 34.

[0057] Fig. 5 of the drawing shows just as Fig. Figure 6 of the drawing shows a permanent magnet 33, which in a cross-sectional view has a cylindrical hat-shaped configuration and is arranged in the receiving chamber 35. As can be seen from Fig. As shown in Figure 9 of the drawing, the permanent magnet 33 can also be arranged in the vertical axis H of the light rail system 37 with an overlap 28 to the underside 14 of the bottom wall 12 of the LED strip 1. This results in the bottom wall 12 of the LED strip 1 exerting a compressive force on the top side 29 of the permanent magnet 33. This ensures that the permanent magnet 33 is securely held in the second receiving chamber 35 and cannot, for example, displace in the longitudinal direction L of the receiving profile 36 of the light rail system 37. The overlap 28 is also in Fig. 5 to Fig. 8 of the drawing is shown.

[0058] Fig. 7 and Fig. Figure 8 of the drawing shows the mounting profile 21, which can, for example, be an elastic extrusion body formed as a strand profile by means of an extrusion process, which forms a receiving space 6 between the two opposing side walls 30 of the extrusion body 31, which is designed to receive the cuboid permanent magnet 33 and has opposing, not shown, positive locking segments or friction locking segments on the side walls 30, which are designed to clamp the permanent magnet 33 between the holding segments of the mounting profile 21 thus formed.

[0059] Fig. Figure 10 of the drawing shows the arrangement of the light rail system 37 on a support profile 38, which has a metallic surface that is ferritic, i.e., magnetizable. The light rail system 37 is held on the support profile by means of the magnetooperative device 32, which is equipped with permanent magnets 33, without the need to fix the receiving profile 36 to the support profile by means of screws.

[0060] Fig. Figure 11 shows an application example of the light rail system 37 according to the invention, which is arranged on a support profile 38 that does not have a magnetizable surface or structure. Therefore, the support profile 38 can be, according to the Fig. 11. The surface may be plastic or wood. In this case, the light track system 37 is supplemented by a ferromagnetic mounting device 43, which may consist of ferromagnetic segments 46 arranged on, for example, a double-sided adhesive tape 44. The adhesive tape 44 is fixed to the surface 45 of the support profile 38 by means of an adhesive surface. It is also sufficient if the ferromagnetic segments 46 are attached to the surface 45 of the support profile with a single-sided adhesive tape 44, since in both cases sufficient holding force is generated by the permanent magnets 43 of the light track system 37 and the ferromagnetic segments of the mounting device 43 so that the light track system 37 can be fixed to the surface 45 of the support profile, as can be seen from the Fig. 11 of the drawing is shown.

[0061] As demonstrated by Fig.As can be seen in Figure 11 of the drawing, the ferromagnetic segments 46 on the adhesive tape 44 can be spaced apart from each other, i.e., they can be spaced apart from each other both in the width direction B of the adhesive tape 44 and in the length direction of the adhesive tape 44, i.e., for example, in the form of two spaced-apart rows of ferromagnetic segments 46, which can be, for example, thin ferromagnetic metal plates.

[0062] The holding force with which the light rail system 37 is fixed to the surface 45 can be further increased with the aforementioned double-sided adhesive tape, but the light rail system 37 is also held securely on the surface 45 by the permanent magnets 33 even without the additional adhesive effect of the double-sided adhesive tape.

[0063] The light rail system according to the invention is characterized, among other things, by the fact that the mounting profile, which is made, for example, of an aluminum material or an aluminum alloy, ensures that the LED strip arranged inside the mounting profile is protected against harsh operating conditions in industrial halls, such as dust or dirt, or against environmental influences in the exterior of buildings, such as moisture or the like. Furthermore, the aluminum material also ensures that the LED strip, which is arranged inside the mounting profile, is protected against electromagnetic interference.

[0064] The track lighting system can also be used for illuminating machines, equipment, or industrial plants, or even for lighting furniture. For example, a magnetizable film can be applied to a non-magnetizable material such as wood or plastic, allowing the track lighting system to be attached to an object made of a non-magnetizable material using the magnetizable film.
