Description

Technical Field

[0001] This invention relates to the field of lighting technology, specifically a low-voltage magnetic track lighting system that is extremely convenient to assemble and use. Background Technology

[0002] Magnetic LED track lights (or magnetic track lights for short) are widely used due to their advantages such as energy saving, low carbon footprint, long lifespan, high luminous efficiency, and excellent lighting effects. Current magnetic track lights allow the lights to be inserted into a track for use. A metal plate is placed inside the track, and magnets are placed inside the lights to achieve a secure hold. They are easy to install and remove, and offer flexible use. Generally, conductive channels and copper wires running along the length of the track are provided for conductivity. Furthermore, to allow for various shapes to be created, connectors are used to join multiple track sections to form track lighting systems of various designs. However, in existing magnetic track lights, the track ends or end connectors and the ends of the connectors (or adapters, splicing joints) are mostly connected by axial insertion, such as the insertion method of the WIFI intelligent control low-voltage safety magnetic track light system with patent number 202122721739.X. The disadvantage of this insertion method is that during the length splicing and shaping process, when the subsequent splicing structure is operated, the track or connector is easily loosened under the action of axial tension. Pulling the track axially during installation will also cause the splicing structure to loosen, resulting in poor robustness and reliability. Chinese patent number 202123070528.0 discloses an ultra-thin magnetic track structure, which splices an ultra-thin straight rail with a corresponding right-angle adapter block and locks it with fixing screws to complete the overall assembly, extending the overall length of the device. This allows for different lengths and forms of assembly according to different usage requirements. While this method of tightening with fixing screws effectively prevents loosening at the connection and enhances the reliability of the structure, it also has the drawbacks of requiring tools for disassembly and assembly, making the process extremely cumbersome and inefficient.

[0003] Furthermore, existing magnetic track lights typically connect the track to the connector in a fixed direction. The assembled track cannot rotate, which severely limits the installation orientation and lighting direction of the magnetic lights on the track, making it inconvenient for use in various scenarios. Summary of the Invention

[0004] The purpose of this utility model is to address the aforementioned problems and deficiencies by providing a low-voltage magnetic track lighting system that can be quickly installed, disassembled, and powered on; is simple and quick to assemble and install without the need for installation tools; has flexible adjustment of splicing direction and length; and features a robust and reliable splicing structure, making it extremely convenient to assemble and use.

[0005] Based on this, a further objective of this utility model is to provide a low-voltage magnetic track lighting system that allows the track bar to rotate relative to the track connector, thereby changing the orientation of the track groove on the track bar, facilitating the change of the orientation of the magnetic light assembly installed on the track bar, and suitable for the usage needs of different scenarios.

[0006] The technical solution of this utility model is implemented as follows:

[0007] The low-voltage magnetic track lighting system described in this utility model, which is extremely convenient to assemble and use, includes at least one track bar, a track connector, and a magnetic lamp assembly. The track bar is provided with a track groove and a conductive communication structure (also called a conductive channel) arranged along its length for connecting and installing the magnetic lamp assembly. Its features are: the ends of the track bar and the ends of the track connector are provided with a separable radial sliding plug-in structure and a separable electrical connection structure. The ends of the track bar and the ends of the track connector achieve a radially detachable structural connection and a detachable circuit connection through the radial sliding plug-in structure and the separable electrical connection structure.

[0008] Preferably, the radial sliding plug-in structure includes a connector at the end of the track bar, a limiting edge one at the outer edge of the connector, a radial groove on the end face of the connector, a limiting edge two at the end of the track connector, and a slider (also called a plug-in strip or plug block) that can cooperate with the radial groove (also called a radial slot). The end of the track connector is radially detachably connected to the connector through the cooperation of limiting edge two and limiting edge one, and the cooperation of the slider and the radial groove. Generally, the two ends of the track connector are respectively provided with limiting edge two and slider, so that both ends can be spliced. Limiting edge one can be integrally set with the outer edge of the connector, or it can be separately set with the outer edge of the connector and then locked to the connector with screws. And the connector can be directly made at the end of the track bar. More preferably, the connector and the track bar are detachably connected, so as to facilitate the removal of the connector and its installation on other lamp tubes. If the track bar is a round tube, the track connector can be axially connected to the lamp tube by installing the connector at the end of the lamp tube.

[0009] Limiting edge one and limiting edge two can be limiting blocks. Preferably, the track strip can be a square tube, and limiting edge one and limiting edge two are both opposing U-shaped limiting edges, with the radial direction referring to the cross-sectional direction of the square tube. When the track strip is a round tube, limiting edge one and limiting edge two are both semi-circular arc-shaped limiting edges. When the track strip and the track connector are connected together through a radial sliding insertion structure, the openings of limiting edge one and limiting edge two can fit together to form a circular sealing edge.

[0010] Furthermore, to allow the track bar to rotate relative to the track connector, thereby changing its orientation and facilitating the adjustment of the orientation of the magnetic light assembly mounted on the track bar, the inner end of the connector is provided with a connecting sleeve that is fixedly connected to the end of the track bar. The connector and the connecting sleeve are connected by an axial threaded tube located in the middle. The middle of both the connector and the connecting sleeve has corresponding through holes for the threaded tube to pass through. Positioning nuts are installed at both ends of the threaded tube. The track bar and the connecting sleeve are rotatably connected to the connector via the threaded tube around its axis. The connecting sleeve is fixedly connected to the track bar by a locking screw. The inner cavity of the track bar has corresponding axial mounting holes that can mate with the locking screw. Of course, the connecting sleeve can also be fixedly connected to the track head in other ways, such as bonding, welding, or lateral bolt locking. Locking with a locking screw is preferred. A further preferred embodiment is that the connector has an axial countersunk hole at the position corresponding to the locking screw. After the locking screw passes through the countersunk hole, the screw head passes through the axial mounting hole on the connecting sleeve and the track bar, and the nut is placed on the outer end of the connecting sleeve to reliably lock the connecting sleeve onto the track bar.

[0011] The detachable electrical connection structure includes a conductive strip disposed in the middle of the connector end face, and the track connector end face is correspondingly provided with multiple conductive protrusions that can contact the conductive strip. A conductive module is connected to the connector, and the conductive strip can be electrically connected to the conductive module. Further, an insulating mounting plate is provided in the middle of the connector end face, and the conductive strip is mounted on the insulating mounting plate (such as an insulating plastic plate). The elongated grooves between the two side edges of the insulating mounting plate and the locking protrusions near the edge of the connector end face form the aforementioned sliding groove.

[0012] The track connectors of this utility model can have various shapes, including but not limited to straight connectors, L-shaped connectors, cross connectors, or T-shaped connectors. When an L-shaped connector is used, it can be a fixed L-shape; preferably, the L-shaped connector is mainly formed by a first circular connector and a second circular connector joined together by a bevel and a connecting stud, and the first and second circular connectors can rotate around the connecting stud. The connecting stud is also provided with retaining springs and locking nuts at both ends, allowing the first and second circular connectors to form an L-shaped connector with a 90-degree connection angle and a straight connector with a 180-degree connection angle. This further expands its application range and allows for more diverse designs.

[0013] The advantages of this utility model are:

[0014] 1. When the installation of this utility model requires shaping, multiple track strips (also called profiles) can be connected using track connectors. Different shapes of track connectors can be selected, allowing for free splicing of different track strips to form various shapes of low-voltage magnetic track lighting systems, meeting diverse usage needs. Furthermore, because the ends of the track strips and the ends of the track connectors are connected radially through a radial sliding insertion structure, the splicing structure will not loosen due to axial tension during the splicing process. The splicing structure has excellent robustness and reliability, and the splicing and installation are simple and quick, requiring no installation tools, making assembly and use extremely convenient. In addition, the splicing structure uses a detachable circuit connection structure, making circuit on / off control extremely convenient.

[0015] Second, this utility model also adopts a connecting sleeve structure on the joint that can be fixedly connected to the track bar and can rotate relative to the joint, so that the track bar can rotate relative to the track connector through the connecting sleeve, thereby changing the orientation of the track groove on the track bar, which makes it easy to change the orientation of the magnetic light assembly installed on the track bar, and is suitable for the use needs of different scenarios.

[0016] Third, this utility model can also connect the lamp tube and the track strip through the track connector to form a track lighting system with a lamp tube in the middle of the track.

[0017] The present invention will be further described below with reference to the accompanying drawings. Attached Figure Description

[0027] like Figures 1-9 As shown, the low-voltage magnetic track lighting system of this utility model, which is extremely convenient to assemble and use, includes at least one track bar 1, track connectors 2, and magnetic lamp assemblies 9. The track bar 1 is provided with a track groove 10 along its length for connecting and installing the magnetic lamp assemblies 9, and a conductive communication structure (also called a conductive channel). An iron sheet 13 is provided at the inner top of the track groove. The conductive channel is located within the track groove 10 and includes insulating plastic on the two inner sidewalls of the track groove along its length and conductive copper strips 14 mounted on the insulating plastic. The conductive copper strips can be connected to a power supply circuit. Signal conductors are also provided on the insulating plastic on the two inner sidewalls of the track groove. The magnetic lamp assembly can be detachably mounted on the track groove through the magnetic attraction between its magnet and the iron sheet, and achieves conductivity through the contact of its conductive contacts with the corresponding conductive copper strips. To enable the track bars to be assembled into various shapes, with simple assembly and good assembly structure reliability, the end of the track bar 1 and the end of the track connector 2 are provided with a separable radial sliding plug-in structure and a separable electrical connection structure. The end of the track bar 1 and the end of the track connector 2 are connected by a radially detachable length structure and a detachable circuit connection through the radial sliding plug-in structure and the separable electrical connection structure.

[0028] The radial sliding plug-in structure includes a connector 3 at the end of the track bar 1, a limiting edge 31 at the outer edge of the connector 3, a radial groove 32 on the end face of the connector, a limiting edge 21 at the end of the track connector 2, and a slider 22 that can cooperate with the radial groove 32. The end of the track connector 2 is radially detachably connected to the connector through the cooperation of the limiting edge 21 and the limiting edge 31, and the cooperation of the slider 22 with the radial groove 32. Generally, the two ends of the track connector are provided with a limiting edge 2 and a slider, respectively, so that both ends can be spliced. Of course, it is also possible to provide a slider on the end face of the connector and a groove on the end face of the track connector, which is equivalent. In this application, during radial movement splicing, the slider 22 can be slightly clamped in the radial groove 32; or the radial groove can be a radial groove with an outer limiting stop, and the slider 22 slides into the radial groove and is limited by the cooperation of the outer limiting stop. When installing a low-voltage magnetic track lighting system, multiple track strips (also called profiles or aluminum profiles) can be connected using track connectors. These connectors can be of various shapes, allowing for flexible and free splicing of different track strips to create low-voltage magnetic track lighting systems of various shapes to meet diverse usage needs. Furthermore, because the ends of the track strips and the ends of the track connectors are connected radially (e.g., vertical or horizontal movement), rather than axially, the splicing structure will not loosen due to axial tension during length splicing. The splicing structure boasts excellent robustness and reliability. In addition, the splicing and installation are simple and quick, requiring no installation tools, making assembly and use extremely convenient. Moreover, the splicing structure uses a detachable circuit connection structure; power is applied when the system is connected and de-energized when disconnected, making circuit control extremely convenient.

[0029] Preferably, the track bar 1 is a circular tube, and both the first limiting edge 31 and the second limiting edge 21 are semi-circular arc-shaped limiting edges. When the track bar 1 and the track connector 2 are connected together through a radial sliding insertion structure, the openings of the first limiting edge 31 and the second limiting edge 21 can mate to form a circular sealing edge. The upper side of the track bar is provided with an installation groove for the installation and sliding adjustment of the hoisting components. A track groove 10 with an opening facing downwards is made in the middle. Magnetic light components such as magnetic light strips or magnetic spotlights with magnets are magnetically installed in the track groove. To allow the track bar to rotate relative to the track connector for easy adjustment of the lighting angle, the inner end of the connector 3 is provided with a connecting sleeve 33 that is fixedly connected to the end of the track bar 1. The connector 3 and the connecting sleeve 33 are connected by an axial threaded tube 34 located in the middle. The middle of both the connector 3 and the connecting sleeve 33 has corresponding through holes for the threaded tube 34 to pass through. Positioning nuts are installed at both ends of the threaded tube 34. The track bar 1 and the connecting sleeve 33 are rotatably connected to the connector 3 via the threaded tube 34 around its axis. This allows the track bar to rotate relative to the track connector via the connecting sleeve, thereby changing the orientation of the track groove on the track bar and facilitating changes in the orientation of the magnetic light assembly installed on the track bar, suitable for various usage scenarios. Generally, the mating point between the circular connecting sleeve and the circular connector can rotate 355 degrees around the center. The connecting sleeve 33 is fixedly connected to the track bar 1 by a locking screw 4. The inner cavity of the track bar 1 is provided with an axial mounting hole 12 that mates with the locking screw 4. The axial mounting hole 12 is preferably an axial snap-fit ​​structure with a side slot. When the track strip 1 is a round tube, the connector can also be installed at the end of the lamp tube. Generally, it is locked to the end plug (or cap) of the lamp tube by a radial screw-on connecting sleeve, and then it can be axially connected to the lamp tube 8 through the track connector 2. Figures 1-2 As shown, the lamp tube is connected to the circular track strip via a connector and track connector, ending at the end. Alternatively, the lamp tube can be connected to the circular track strip via a connector and track connector, with the lamp tube acting as an intermediate connector and also supplying power to the track strip below.

[0030] A conductive module 5 is connected to the connector 3. The conductive module can be installed in the track groove 10 of the track bar, and a small bottom cover can also be installed below the conductive module. The detachable electrical connection structure includes a conductive strip 6 located in the middle of the end face of the connector 3. The conductive strip is electrically connected to the conductive module 5. The end face of the track connector 2 is provided with multiple conductive protrusions 7 that can contact the conductive strip 6. The conductive module contacts the conductive copper strip in the track bar through power supply contacts on both sides and transmits power to the conductive strip 6 on the end face of the connector. Of course, the conductive strip can also be electrically connected to the conductive copper strip through wires, but such a structure is inconvenient to disassemble and assemble, and the structure is not very reliable. Therefore, it is preferable to use a conductive module. The conductive module 5 is also provided with signal contacts and signal lines for connecting the dimming system. Generally, multiple conductive protrusions are provided on both ends of the track connector. The conductive protrusions at both ends are electrically connected through wires installed in the track connector. Furthermore, an insulating mounting plate is provided in the middle of the end face of the connector 3, and the conductive strip 7 is mounted on the insulating mounting plate. The long groove between the two sides of the insulating mounting plate and the locking protrusion provided near the edge of the end face of the connector 3 forms the above-mentioned sliding groove 32, which has a simple and reliable structure.

[0031] The shape of the track connector 2 in this application can vary, including but not limited to a straight connector, an L-shaped connector (such as...). Figure 5 and Figure 7 (as shown), Type X connector or Type T connector (such as...) Figure 8 (As shown). Furthermore, the L-shaped connector can be a fixed L-shape. Preferably, the L-shaped connector is mainly formed by the mating of a first circular connector 23 and a second circular connector 24 through an inclined surface and a connecting stud 25, and the first circular connector 23 and the second circular connector 24 can rotate around the connecting stud 25. The connecting stud 25 is also provided with a retaining spring 26 and a locking nut at both ends, so that the first circular connector 23 and the second circular connector 24 can form an L-shaped connector with a connection angle of 90 degrees and a straight connector with a connection angle of 180 degrees. (As shown) Figure 3 This is a schematic diagram showing the structure of an L-shaped connector converted into a straight connector and connected to two track bars. Both the first circular connector 23 and the second circular connector 24 have a limiting edge, a conductive protrusion, and a slider on their outer end faces. The conductive protrusions on the two outer end faces are connected by internal electrical circuitry. The inner end faces are inclined surfaces that can mate and connect. When the track connector is a T-shaped connector, all three end faces have a limiting edge, a conductive protrusion, and a slider that can mate and connect with the connector.
