Description

Technical Field

[0001] This utility model relates to the field of lighting technology, specifically to a magnetic track and a lighting system equipped with the magnetic track. Background Technology

[0002] Track lights, as one of the mainstream lighting fixtures in the current indoor lighting field, are favored by consumers for their convenient and efficient installation and flexible adjustment of lighting position. During installation, the power adapter of the track light is inserted into the magnetic track, causing the first magnetic component on the power adapter to magnetically attract and engage with the second magnetic component installed in the magnetic track, thus fixing the track light on the track. Simultaneously, the spring contacts on the power adapter make close contact with the conductive conductor installed in the magnetic track, allowing the magnetic track to not only provide power to the track light but also transmit relevant control commands.

[0003] However, the main structure of existing magnetic tracks is generally made of aluminum profiles. Conventional aluminum profiles (such as AL6063 and AL6061 series aluminum alloys) are non-magnetic materials and do not have the physical property of being attracted by permanent magnets. This means that magnetic tracks must be equipped with additional magnetic components (such as iron sheets, permanent magnets, etc.) to meet the requirements for attracting and fixing the guide lights. As a result, magnetic tracks have the following shortcomings: First, the high material cost of aluminum profiles increases the basic manufacturing cost of magnetic tracks. Secondly, the addition of magnetic components further increases the material cost of the magnetic track and also increases the structural complexity of the magnetic track (a specific structure is needed to fix the magnetic components), which further increases the overall manufacturing cost of the magnetic track. Utility Model Content

[0004] The primary objective of this invention is to provide a magnetic track with low production costs.

[0005] The second objective of this invention is to provide a lighting system equipped with the aforementioned magnetic track.

[0006] To achieve the first objective of this utility model, this utility model provides a magnetic track, which includes a first track component and two second track components arranged in a mirror-symmetrical manner. The first track component includes two oppositely arranged side plates and a top plate connected to the top of the two side plates. The top plate is bent inward into the first track component to form two first protrusions and a second protrusion. The two first protrusions are located between the two side plates, and a first locking position is formed between the first protrusion and the side plate closest to it. The second protrusion is located between the two first protrusions. The two second track components correspond one-to-one with the two side plates. The second track component includes a first plate portion, and a vertical plate portion is formed by bending the top of the first plate portion. The first plate portion is installed on the inner side of the corresponding side plate, and a second locking position is formed between the vertical plate portion and the side plate. A clearance position is formed between the vertical plate portion and the first protrusion. Both the first track component and the second track component are made of cold-rolled carbon steel plate.

[0007] As can be seen from the above, compared with traditional magnetic tracks made of aluminum profiles, the use of cold-rolled carbon steel plates to make the first and second track components eliminates the need for additional magnetic components (such as iron sheets) to be installed on the magnetic track. This reduces material costs and simplifies the structure of the magnetic track (e.g., eliminating the need for a mating structure to fix the magnetic components). Furthermore, the density of cold-rolled carbon steel plates is higher than that of aluminum profiles (such as AL6063), resulting in a higher-quality feel for the same size magnetic track compared to traditional magnetic tracks. The second protrusion is used to cooperate with the permanent magnet on the power adapter of the track light, allowing the track light to be attracted and fixed on the magnetic track. The cooperation of the first locking position, the second locking position, and the clearance position is used to accommodate the conductive conductor, enabling the magnetic track to supply power to the track light.

[0008] A further option is to have a snap-fit ​​part formed between the first plate and the upright plate, with the snap-fit ​​part extending toward the other first plate.

[0009] As can be seen from the above, by adding a snap-fit ​​part, the snap-fit ​​part can cooperate with the buckle on the power adapter of the rail light to help the second protrusion and permanent magnet further fix the rail light on the magnetic track, prevent the rail light from falling off the magnetic track, and improve the safety of use.

[0010] In a preferred embodiment, the second track member further includes a second plate and a wing. The second plate is folded over from the bottom of the first plate, forming a slot between the second plate and the first plate. A side plate is inserted into the slot. The wing is folded over from the top of the second plate and extends away from the side plate.

[0011] As can be seen from the above, the setting of the second plate helps to improve the connection strength between the first and second track components; the wing can be covered by putty or paint during the decoration and plastering stage. On the one hand, it can hide the fasteners, cover up the cutting error of the ceiling to accommodate the magnetic track, avoid secondary repairs, and reduce the risk of wall cracking after plastering is completed, making the magnetic track appear to be embedded in the wall. On the other hand, the wider contact surface of the wing forms an anchoring edge, which can improve the pull-out resistance of the magnetic track, allowing the magnetic track to support multiple guide lights.

[0012] Another preferred embodiment is that the magnetic track also includes two conductive conductors, each of which includes an insulating protective element and a conductive component. The insulating protective element includes a main body, a first insertion part, and a second insertion part. The first insertion part is inserted into a first locking position, and the second insertion part is inserted into a second locking position. The main body is located within a clearance position, and the conductive component is partially covered by the main body and exposed at the clearance position.

[0013] As can be seen from the above, the conductive conductor is used to establish an electrical connection between the magnetic track and the guide light, thereby powering the guide light. Through the design of the conductive conductor, it is possible to directly insert the conductive conductor into the installation area formed by the first slot, the second slot, and the clearance position, simplifying the assembly operation of the conductive conductor with the first track component and the second track component.

[0014] A further proposed solution is that the conductive component includes a power supply conductive terminal and a signal conductive terminal, which are insulated from each other.

[0015] As can be seen from the above, through the structural design of the conductive components, the magnetic track can provide a stable power supply voltage to the track light through the power supply conductive terminal, and at the same time output control signals to the track light through the signal conductive terminal, so that the track light can accurately execute the preset lighting mode related to the control command according to the received control command.

[0016] A further proposed solution is to have an empty slot on the side of the main body away from the conductive components.

[0017] As can be seen from the above, since the main body is an injection molded part and the thickness of the main body is greater than that of the second insertion part of the first insertion part, by setting a hollow groove on the main body, on the one hand, it can avoid the surface shrinkage and depression of the insulating protective part during molding and cooling, reduce internal stress, and prevent the insulating protective part from cracking, warping and deformation, etc. On the other hand, it can also reduce the material used for the insulating protective part, reduce costs, and realize the lightweight design of the conductive conductor and magnetic track.

[0018] A further proposed solution is to form both the first and second track components using a roll forming process.

[0019] As can be seen from the above, the roll forming process for the first and second track components ensures good continuity in the forming process, eliminates impact during forming, and results in virtually no scratches or springback on the surface, while maintaining high dimensional accuracy. Furthermore, the forming efficiency is high, eliminating the need for dedicated molds and reducing mold costs. Moreover, it ensures uniform work hardening of the first and second track components, resulting in increased strength and low residual stress, thus preventing deformation during subsequent assembly and welding.

[0020] A further proposed solution is to fix the first and second track components together using a welding process.

[0021] As can be seen from the above, using welding to fix the first and second track components can ensure the connection strength and reliability between them, and optimize the load-bearing capacity of the magnetic track.

[0022] To achieve the second objective of this utility model, this utility model provides a lighting system, including a rail light. The rail light includes a power adapter and a lamp body. The power adapter is provided with a permanent magnet, and the lamp body is installed on the power adapter. The lighting system also includes the aforementioned rail light. The power adapter is inserted into a magnetic track, and the permanent magnet is magnetically attracted and fixed to a second protrusion.

[0023] As can be seen from the above, by configuring the aforementioned magnetic track, the lighting system can reduce costs on the one hand, and enhance the overall quality of the product on the other.

[0024] A further solution is to add a latch to the power adapter, which is attached to the upper side of the latch.

[0025] As can be seen from the above, this design can further enhance the connection strength between the guide light and the magnetic track, and further prevent the guide light from detaching from the magnetic track due to its own gravity. Attached Figure Description

[0032] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0033] Lighting System Examples Reference Figure 1 and Figure 2 The lighting system 100 includes a magnetic track 1 and a rail light 2; the rail light 2 is detachably mounted on the magnetic track 1 and is electrically connected to the magnetic track 1, so that the magnetic track 1 can provide a stable voltage to the rail light 2. In addition, the magnetic track 1 can also output control signals to the rail light 2 to enable the rail light 2 to execute relevant lighting modes.

[0034] Combination Figures 3 to 5 The magnetic track 1 includes a first track component 11, a second track component 12, and a conductive conductor 13. The first track component 11 includes two side plates 111 and a top plate 112. The two side plates 111 are arranged in a mirror symmetrical manner and are almost parallel to each other. The top plate 112 is connected to the top of the two side plates 111, and the top plate 112 and the two side plates 111 are integrally formed.

[0035] The top plate 112 is bent inward toward the first track member 11 to form two first protrusions 1121 and a second protrusion 1122. The two first protrusions 1121 are preferably arranged in a mirror symmetrical manner, and the two first protrusions 1121 correspond one-to-one with the two side plates 111, so that a first locking position 11211 is formed between one first protrusion 1121 and the corresponding side plate 111 (that is, a first locking position 11211 is formed between the first protrusion 1121 and the side plate 111 closest to it). In addition, the two first protrusions 1121 are located between the two side plates 111; the second protrusion 1122 is located between the two first protrusions 1121.

[0036] The first track component 11 is integrally formed from cold-rolled carbon steel sheet using a roll forming process. This design ensures the continuity of the forming process of the first track component 11, and makes the forming process impact-free, with almost no scratches or springback on the surface. It also ensures high dimensional accuracy of the first track component 11. In addition, using a roll forming process to form the first track component 11 has the advantages of high forming efficiency and no need for a special mold, effectively reducing mold costs. Furthermore, it also ensures uniform work hardening of the first track component 11, increasing its strength while minimizing residual stress, preventing deformation during subsequent assembly and welding with the second track component 12.

[0037] There are two second track members 12, and the two second track members 12 correspond one-to-one with the two side plates 111 of the first track member 11, such that one second track member 12 is installed on the corresponding side plate 111; the second track member 12 includes a first plate portion 121, a second plate portion 122 and a wing portion 123.

[0038] The first plate portion 121 is located inside the side plate 111, and the top of the first plate portion 121 is bent to form a vertical plate portion 1211 and a snap-fit ​​portion 1212. The vertical plate portion 1211 is substantially parallel to the side plate 111, and a second snap-fit ​​position 12111 is formed between the vertical plate portion 1211 and the corresponding side plate 111. In addition, a clearance position 12112 is formed between the top of the vertical plate portion 1211 and the first protrusion 1121 located above it. The first snap-fit ​​position 11211, the second snap-fit ​​position 12111, and the clearance position 12112 form an installation area for the conductive conductor 13. The snap-fit ​​portion 1212 is bent between the first plate portion 121 and the vertical plate portion 1211, and the snap-fit ​​portion 1212 extends toward the other first plate portion 121, so that the snap-fit ​​portion 1212 is approximately a platform perpendicular to the side plate 111.

[0039] The second plate portion 122 is folded from the bottom of the first plate portion 121, forming a U-shaped structure between them, thus creating a slot 120. When the second track member 12 is assembled with the first track member 11, the side plate 111 is inserted into the slot 120. Therefore, the second plate portion 122 helps to improve the connection strength between the first track member 11 and the second track member 12. Furthermore, when the second track member 12 is connected to the first track member 11, they can be welded together to ensure the connection strength and reliability, thereby optimizing the load-bearing capacity of the magnetic track 1.

[0040] The wing 123 is folded from the top of the second plate 122, so that the wing 123 extends away from the corresponding side plate 111; wherein, the wing 123 is preferably substantially perpendicular to the second plate 122. The wing 123 can be covered with putty or paint during the finishing and plastering stage, so that it becomes integrated with the wall. Under the function of the wing 123, on the one hand, fasteners (so the bolts or rivets that fix the wing 123 to the wall / ceiling) can be hidden, and the cutting errors of the wall / ceiling to accommodate the magnetic track 1 can also be concealed, avoiding the need for secondary repairs. In addition, it can also reduce the risk of wall cracking after the plastering is completed, making the magnetic track 1 appear to be embedded in the wall; on the other hand, the wider contact surface of the wing 123 can be used to form an anchoring edge, thereby improving the pull-out resistance of the magnetic track 1, so that the magnetic track 1 can support a larger number of guide lights 2 without detaching from the wall / ceiling.

[0041] Similarly, the second track component 12 is integrally formed from cold-rolled carbon steel sheet using a roll forming process. This design ensures the continuity of the forming process of the second track component 12, and makes the forming process impact-free, with almost no scratches or springback on the surface. It also ensures high dimensional accuracy of the second track component 12. In addition, using a roll forming process to form the second track component 12 has the advantages of high forming efficiency and no need for a special mold, effectively reducing mold costs. Furthermore, it also ensures uniform work hardening of the second track component 12, increasing its strength while minimizing residual stress, preventing deformation during subsequent assembly and welding with the first track component 11. Compared to traditional magnetic tracks made of aluminum profiles, the use of cold-rolled carbon steel plates to make the first track component 11 and the second track component 12 eliminates the need for additional magnetic components (such as iron sheets) to be installed on the magnetic track 1. This reduces material costs and simplifies the structure of the magnetic track 1 (e.g., eliminating the need for a mating structure to fix the magnetic components). Furthermore, since the density of cold-rolled carbon steel plates is higher than that of aluminum profiles (such as AL6063), the magnetic track 1 of this application has a higher quality feel than traditional magnetic tracks of the same size.

[0042] There are two conductive conductors 13, each corresponding to one of the two mounting areas; that is, one conductive conductor 13 is installed in one mounting area. The conductive conductors 13 extend along the length of the magnetic track 1. Each conductive conductor 13 includes an insulating protective element 131 and a conductive component 132. The insulating protective element 131 includes a main body 1311, a first insertion part 1312, and a second insertion part 1313. When the conductive conductor 13 is assembled with the first track component 11 and the second track component 12, at the height position of the conductive conductor 13, the first insertion part 1312 is located above the main body 1311 and is inserted into the first locking position 11211; the second insertion part 1313 is located below the main body 1311 and is inserted into the second locking position 12111; while the main body 1311 is located within the clearance position 12112.

[0043] The conductive conductor 13 is used to establish an electrical connection between the magnetic track 1 and the guide light 2, thereby powering the guide light 2. Through the structural design of the insulating protective component 131, the assembly operation can be effectively simplified when the conductive conductor 13 is assembled with the first track component 11 and the second track component 12, making the disassembly and assembly of the conductive conductor 13 more convenient, thus facilitating the inspection and replacement of the conductive conductor 13.

[0044] The conductive component 132 is integrally molded onto the main body 1311 of the insulating protective component 131 using an insert injection molding process. When the conductive conductor 13 is installed on the first track component 11 and the second track component 12, the conductive component 132 has an exposed portion at the clearance position 12112 to facilitate the establishment of an electrical connection between the track light 2 and the conductive component 132. The insulating protective component 131 encapsulates the conductive component 132 to prevent the first track component 11 and the second track component 12 from conducting with the conductive component 132, thereby providing safety during use and avoiding safety hazards such as short circuits and leakage.

[0045] The conductive component 132 preferably includes a power supply conductive terminal 1321 and a signal conductive terminal 1322, which are insulated from each other. The power supply conductive terminal 1321 enables the magnetic track 1 to provide a stable power supply voltage to the rail light 2, while the signal conductive terminal 1322 enables the magnetic track 1 to output a control signal to the rail light 2, thereby allowing the rail light 2 to accurately execute a preset lighting mode related to the received control command. Both the power supply conductive terminal 1321 and the signal conductive terminal 1322 are elongated strip structures extending along the length of the magnetic track 1, ensuring that the rail light 2 can establish a reliable electrical connection with the magnetic track 1 regardless of its position on the track 1.

[0046] Furthermore, since the thickness of the main body 1311 (in the normal direction of the side plate 111) is greater than that of the first insertion part 1312 and the second insertion part 1313, a slot 13111 is provided on the main body 1311. The number and width (along the height direction of the conductive conductor 13) of the slots 13111 are adjusted according to the size of the main body 1311 and the first insertion part 1312 and the second insertion part 1313, and one to three slots are usually preferred. The slots 13111 extend along the length direction of the magnetic track 1 and penetrate the main body 1311. Since the main body 1311 is an injection molded part, by setting a hollow groove 13111 on the main body 1311, it is possible to effectively avoid surface shrinkage and depression of the insulating protective part 131 during molding and cooling, reduce internal stress, and prevent the insulating protective part 131 from cracking, warping and deformation. Furthermore, the design of the hollow groove 13111 can also appropriately reduce the material used in the insulating protective part 131, thereby reducing costs and realizing the lightweight design of the conductive conductor 13 and the magnetic track 1.

[0047] Combination Figure 6 The rail light 2 includes a power adapter 21 and a lamp body 22. The top of the power adapter 21 is provided with a permanent magnet 211, so that when the rail light 2 is assembled with the magnetic track 1, the power adapter 21 can be inserted into the magnetic track 1, so that the permanent magnet 211 is magnetically attracted and fixed to the second protrusion 1122, thereby fixing the rail light 2 on the magnetic track 1.

[0048] In addition, the side of the magnetic track 1 is provided with a buckle 212, a power supply conductive contact 213, and a signal conductive contact 214. When the power adapter 21 is inserted into the magnetic track 1 and the permanent magnet 211 is magnetically attracted and fixed to the second protrusion 1122, the buckle 212 can be fastened to the upper side of the latching part 1212. The cooperation between the buckle 212 and the latching part 1212 helps the second protrusion 1122 and the permanent magnet 211 to further fix the guide light 2 on the magnetic track 1, preventing the guide light 2 from falling off the magnetic track 1 due to its own weight, thus improving safety. The power supply conductive contact 213 contacts the power supply conductive terminal 1321 after the power adapter 21 is inserted into the magnetic track 1, thereby establishing a power supply line. Similarly, the signal conductive contact 214 contacts the signal conductive terminal 1322 after the power adapter 21 is inserted into the magnetic track 1, thereby establishing a control line.

[0049] The lamp body 22 contains components such as a light-emitting module and optical elements, and is mounted on the power adapter 21. Preferably, as in this embodiment, when the guide rail lamp 2 is assembled with the magnetic track, the lamp body 22 can be completely housed within the magnetic track 1 to enhance its overall aesthetics. It is understood that in some embodiments, the lamp body 22 may also be located entirely or partially outside the magnetic track 1.

[0050] In summary, the design of the magnetic track 1 of the lighting system 100 helps to reduce manufacturing costs, while also making the overall assembly of the magnetic track 1 simpler and more convenient. Furthermore, the use of cold-rolled carbon steel plates to make the first track component 11 and the second track component 12 can better enhance the overall quality of the product.

[0051] Finally, it should be emphasized that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
