Description
Technical Field
[0001] This invention relates to the field of energy-saving lighting technology, and more specifically, to a quick-release sliding rail magnetic LED light. Background Technology
[0002] As a typical representative of energy-saving lighting equipment, LED lights have become the absolute mainstay of the current and future lighting market due to their low energy consumption, long lifespan, excellent environmental protection, and outstanding light quality.
[0003] In recent years, LED magnetic track lights have become an important element in interior lighting design. The light fixtures are magnetically attached to a track, which acts like a large "power strip" to supply power to the track lights. Magnetic attachment can be divided into weak and strong magnets; weak magnets are suitable for lightweight light fixtures, while strong magnets are needed for heavier ones. Strong magnets increase the connection strength between the light fixture and the track, but they also present the following problems in places where the lighting layout needs frequent adjustments (such as exhibition halls):
[0004] Because of the high connection strength between the strong magnet and the track, on the one hand, it increases the resistance of the lamp body within the track; on the other hand, when the lamp body is removed from the track or moved within the track, the lamp body will also exert pulling and pushing forces on the track through the magnet, affecting the stability of the connection between the track and surrounding buildings. In addition, when the lamp body moves within the track, friction will also occur between the contacts inside the lamp body and the metal strips inside the track, which will accelerate the wear of the metal strips after frequent movement. Summary of the Invention
[0005] The purpose of this invention is to provide a quick-release sliding rail magnetic LED light, which solves the problem mentioned in the background art by changing the originally fixed magnet block to a sliding one, and adjusting the magnetic attraction force by the sliding distance. This is because the high connection strength between the strong magnet and the rail affects the movement of the light body and the stability of the connection between the rail and the surrounding buildings.
[0006] To achieve the above objectives, a quick-release sliding rail magnetic LED light includes a rail, a junction box, and a lamp body. The rail is provided with a metal strip and a conductive strip. The junction box is electrically connected to the lamp body. The junction box is elastically provided with a conductive part and slidably provided with a magnetic carrier.
[0007] The conductive part is located on one side of the conductive strip and contacts the conductive strip through elastic force;
[0008] The magnet carrier contains a magnet block, which drives the magnet block to move, giving the magnet block a first position and a second position. In the first position, the magnet block is in contact with the metal strip. In the second position, the magnet block detaches from the metal strip, reducing the magnetic attraction between the magnet block and the metal strip. The conductive part is located between the magnet block and the conductive strip, and the magnet block attracts the conductive part to detach from the conductive strip through magnetic attraction.
[0009] It also includes a driving component, which drives the magnet carrier to switch the magnet block back and forth between the first position and the second position.
[0010] In the above technical solution, the magnetic carrier can move the magnetic block away from the metal strip, thus reducing the magnetic attraction between the magnetic block and the metal strip. When the lamp body needs to be moved, the pulling force exerted by the magnetic block on the track will be reduced, minimizing the impact on the track.
[0011] Based on this, the junction box includes a housing, inside which a sliding chamber and a junction chamber are disposed, with the junction chamber located on both sides of the sliding chamber. Wherein:
[0012] The magnet carrier includes a support plate located in the sliding chamber and a guide post that slides vertically through the support plate. The guide post is fixedly installed at the bottom of the sliding chamber. The top of the support plate is fixedly connected to the magnet block. The top of the outer shell is provided with an opening for the magnet block to enter. The magnet block adheres to the surface of the metal strip through the opening to achieve magnetic fixation.
[0013] One end of the conductive part is located inside the receiving chamber, and the other end slides through the side wall of the outer shell. An insulating plate is fixedly connected to the end of the conductive part located inside the receiving chamber. An elastic element, which is a spring, is provided between one side of the insulating plate and the side wall of the receiving chamber to elastically connect the two. A metal block is provided on the side of the insulating plate facing the magnet. When the magnet is in the second position, the metal block is attracted by the magnet.
[0014] Based on this, the driving component is a pull ring located at least on one side of the housing. The pull ring is fixedly connected to the support plate, and drives the support plate to reciprocate. During operation, one hand pushes the lamp body upward, while the other hand pulls the pull ring downward. Therefore, the downward pull force exerted on the track when the magnet detaches from the metal strip is offset by the force exerted by the operator pushing the lamp body.
[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0016] 1. In this quick-release sliding rail magnetic LED light, since the magnet is movably installed inside the junction box, when the light body needs to be moved, the magnet is controlled to move downwards to move away from the metal strip. On the one hand, the magnetic attraction between the magnet and the metal strip is reduced after the magnet moves downwards, and the force exerted on the track by the light body moving in the track is also reduced, thus reducing the impact on the track. On the other hand, after moving downwards, the conductive part will be attracted to detach from the conductive strip, so that when the junction box moves in the track, there will be no friction between the conductive part and the conductive strip, thus avoiding wear on the conductive strip.
[0017] 2. In this quick-release sliding rail magnetic LED light, when the driving magnet moves downward, the operator pushes the light body upward with one hand and pulls the pull ring downward with the other hand. Therefore, the downward pull force exerted on the rail when the magnet detaches from the metal strip will be offset by the force exerted by the operator pushing the light body. This avoids applying a pulling force to the rail when the magnet detaches from the metal strip, thus improving the stability of the connection between the rail and the building.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.
[0030] To address the issue that the high connection strength between the strong magnet and the track 100 affects the movement of the lamp body 200 and the stability of the connection between the track 100 and surrounding buildings, this invention provides a quick-release sliding rail magnetic LED light. For example... Figure 1 As shown, it comprises three parts: a track 100, a junction box 110, and a lamp body 200. The track 100 is primarily installed on the ceiling or wall indoors, and can be fixed or suspended. For example, when the ceiling is high, the track 100 is suspended from the ceiling using a hanging rope. Specifically, the structure of the track 100 is as follows... Figure 2As shown, the track 100 has a U-shaped structure. Taking its installation on a ceiling as an example, the opening of the track 100 faces downwards. The track 100's interior includes two parts: a metal strip 101 and a conductive strip 102. The lengths of both the metal strip 101 and the conductive strip 102 are the same as the length of the track 100. The metal strip 101 is installed in a slot on the inner wall of the top of the track 100 for magnetic engagement with the junction box 110. The conductive strips 102 are symmetrically arranged on the inner walls of both sides of the track 100, preferably two on each side to improve conductivity stability. To prevent the track 100 from becoming electrified, the conductive strips 102 are insulated from the track 100 by an insulating part 103. The insulating part 103 is fixed in a slot on the inner wall of the track 100 and its length is the same as the length of the conductive strip 102. In addition, fixing plates 104 are provided on both sides of the track 100. The fixing plates 104 are perpendicular to the side wall of the track 100. The fixing plates 104 are fixed to the ceiling or wall by screws to achieve the fixed installation of the track 100.
[0031] The junction box 110 is fixedly connected to the lamp body 200. The volume of the junction box 110 and the lamp body 200 after connection is adapted to the internal space of the track 100, so that the junction box 110 and the lamp body 200 can be placed inside the track 100. Figure 3 As shown, the junction box 110 has a conductive part 116 elastically arranged inside and a magnetic carrier 130 slidably arranged therein. The conductive part 116 is located on one side of the conductive strip 102 and contacts the conductive strip 102 through elasticity. The conductive part 116 is connected to the lamp body 200. When the conductive part 116 contacts the conductive strip 102, current flows through the conductive part 116 to the lamp body 200, illuminating the lamp body 200. The magnetic carrier 130 contains a magnetic block 120, which drives the magnetic block 120 to move. This gives the magnetic block 120 a first position A and a second position B. In the first position A, the magnetic block 120 contacts the metal strip 101, and the track 100 and junction box 110 achieve a stable magnetic connection. In the second position B, the magnetic block 120 disengages from the metal strip 101. At this time, the magnetic attraction between the magnetic block 120 and the metal strip 101 decreases, and the impact of adjusting the lighting layout on the track 100 also decreases. Furthermore, when the magnet block 120 is in the second position B, the conductive part 116 is located between the magnet block 120 and the conductive strip 102. The magnet block 120 attracts the conductive part 116 away from the conductive strip 102 through magnetic attraction. With this design, when the magnet block 120 detaches from the metal strip 101, on the one hand, the magnetic attraction strength is reduced, and on the other hand, the magnet block 120 will move closer to the conductive part 116, thereby realizing the detachment of the conductive part 116 from the conductive strip 102 and reducing the wear of the conductive strip 102 during movement.
[0032] In the above, the magnet carrier 130 is connected to the drive unit 140, and the drive unit 140 drives the magnet carrier 130 to realize the reciprocating switching of the magnet block 120 between the first position A and the second position B.
[0033] In other words, since the magnet 120 is movably disposed within the junction box 110, when the lamp body 200 needs to be moved, the magnet 120 is controlled to move downwards away from the metal strip 101. On the one hand, the magnetic attraction between the magnet 120 and the metal strip 101 is reduced after the magnet moves downwards, and the force exerted on the track 100 by the lamp body 200 as it moves within the track 100 is also reduced, thus reducing the impact on the track 100. On the other hand, after moving downwards, the conductive part 116 will be attracted away from the conductive strip 102, so that when the junction box 110 moves within the track 100, no friction will occur between the conductive part 116 and the conductive strip 102, thus avoiding wear on the conductive strip 102.
[0034] Specifically, such as Figure 4 and Figure 5 As shown, the junction box 110 includes a housing 111, which is hollow and has three chambers separated by two vertically arranged baffles. The middle chamber is a sliding chamber 114, and the chambers on either side of the sliding chamber 114 are junction chambers 115. The sliding chamber 114 is the widest, primarily used for switching between the first position A and the second position B. The two junction chambers 115 have the same width and are used to install the conductive part 116. The installation structures within the sliding chamber 114 and the junction chambers 115 will be described in detail below:
[0035] like Figure 4 As shown, the magnet carrier 130 includes a support plate 131 located within a sliding chamber 114 and guide posts 132 perpendicularly penetrating the support plate 131. The guide posts 132 are fixedly disposed at the bottom of the sliding chamber 114 to limit the movement of the support plate 131, ensuring that the support plate 131 can only slide along the axial direction of the guide posts 132. The guide posts 132 are located at both ends of the support plate 131, preferably two at each end. The specific positions of the guide posts 132 can be found in [reference needed]. Figure 4The top of the support plate 131 protrudes upwards at the portion corresponding to the magnet 120, and the protruding portion has a groove to accommodate the magnet 120. The magnet 120 is fixed in the groove by adhesive or bolts, allowing it to move synchronously with the support plate 131. Additionally, the top of the outer casing 111, corresponding to the portion of the magnet 120, has a through-hole 112. The length and width of the through-hole 112 correspond to the length and width of the protruding portion of the support plate 131, allowing the protruding portion of the support plate 131 to enter the through-hole 112. Furthermore, the height of the protruding portion of the support plate 131 is not lower than the height of the through-hole 112, and the height of the magnet 120 is the same as the height of the protruding portion of the support plate 131. With this design, after the protruding portion of the support plate 131 enters the through-hole 112, the top of the magnet 120 is flush with the top of the outer casing 111, allowing the top of the magnet 120 to contact the metal strip 101. At this point, the lamp body 200 is in the first position A.
[0036] The conductive portion 116 can be a sheet-like structure, a cylindrical structure, or other types. This invention uses a cylindrical structure as an example to describe the conductive portion 116 in detail. Figure 5 As shown, the conductive part 116 is arranged laterally, with one end located inside the receiving chamber 115 and the other end sliding through the side wall of the outer casing 111. When each receiving chamber 115 has two conductive parts 116, one end of the two conductive parts 116 (referring to the end located inside the receiving chamber 115) is fixedly connected to an insulating plate 117. An elastic element 118 is provided between one side of the insulating plate 117 and the side wall of the receiving chamber 115 to elastically connect the two. The elastic element 118 can be a spring, a sheet, etc. Under the elastic action of the elastic element 118, the conductive part 116 is pushed towards the conductive strip 102, thereby pressing tightly against the side wall of the conductive strip 102. In addition, the conductive part 116 is usually made of copper as the conductive material. Therefore, when the conductive part 116 is made of copper, the magnet block 120 cannot attract the conductive part 116 to move. Therefore, the present invention provides a metal block 119 on the side of the insulating plate 117 facing the magnet block 120. The height of the metal block 119 is the same as the height of the magnet block 120 when it is in the second position B, so that the magnet block 120 attracts the metal block 119 when it is in the second position B.
[0037] When implementing, such as Figure 4 and Figure 5 As shown, the bottom of the outer casing 111 is designed as an open structure, and a base plate 113 is provided at the bottom of the outer casing 111. The base plate 113 is detachably connected to the bottom of the outer casing 111 by bolts. During the assembly stage, the base plate 113 is removed from the opening at the bottom of the outer casing 111, at which point components such as the magnet carrier 130, the insulating plate 117, and the elastic element 118 can be assembled into the outer casing 111. The base plate 113 is also detachably connected to the lamp body 200.
[0038] In this invention, the drive unit 140 can be either electrically driven or manually operated. This will be described in detail below through the following embodiments.
[0039] In some embodiments, the drive element 140 is a miniature electric actuator (not shown in the figure). The miniature electric actuator is fixedly mounted at the bottom of the sliding chamber 114, and its movable end is fixedly connected to the bottom of the support plate 131. When it is necessary to switch the magnet block 120 to the second position B, the miniature electric actuator is controlled to retract. At this time, the miniature electric actuator pulls the support plate 131 downward, and the support plate 131 causes the magnet block 120 to disengage from the metal strip 101. This embodiment is mainly applicable to larger lamps, which have a large internal space, thus allowing for the installation of miniature electric actuators.
[0040] In other embodiments, such as Figure 3 As shown, the driving component 140 is a pull ring 141 located at least on one side of the housing 111 (or on both sides of the housing 111). The pull ring 141 has an elliptical structure, with its bottom close to the opening of the track 100 for easy gripping by the operator. The pull ring 141 is fixedly connected to the support plate 131. Specifically, a connecting rod is fixedly connected to one side of the pull ring 141, with one end of the connecting rod sliding through the housing 111 and fixedly connected to one end of the support plate 131. When it is necessary to switch the magnet block 120 to the second position B, one hand pulls down the pull ring 141, while the other hand controls the lamp body 200 to prevent the lamp body 200 and the housing 111 from moving down. At this time, the pull ring 141 drives the support plate 131 to move down, and the support plate 131 drives the magnet block 120 to detach from the metal strip 101.
[0041] The working principle of this invention will be described in detail below:
[0042] First, such as Figure 6 As shown, Figure 6 The central magnet 120 is in position A, at which point it contacts the metal strip 101, fixing the junction box 110 and the lamp body 200 within the track 100. Simultaneously, the distance L1 between the magnet 120 and the metal block 119 is relatively large, and they are at different heights. Therefore, the metal block 119 is not affected by the magnetism of the magnet 120, allowing the elastic element 118 to normally push the conductive part 116 against the side wall of the conductive strip 102. The lamp body 200 is electrically connected to the conductive part 116; when the conductive strip 102 contacts the conductive part 116, the lamp body 200 is energized and illuminated.
[0043] Then, as Figure 7As shown, when the position needs to be moved, one hand pushes the lamp body 200 upwards, and the other hand pulls the pull ring 141 downwards. When the downward pulling force applied to the pull ring 141 is greater than the magnetic attraction between the magnet 120 and the metal strip 101, the pull ring 141 drives the support plate 131 and the magnet 120 downwards. At this time, the magnet 120 moves down to the second position B. Since the distance between the magnet 120 and the metal strip 101 increases, the magnetic attraction between them decreases. At this time, moving the junction box 110 and the lamp body 200 will not exert a force on the track 100. At the same time, after the magnet 120 moves down, the distance L2 between it and the metal block 119 becomes closer. At this time, the magnet 120 attracts the metal block 119, and the metal block 119 drives the conductive part 116 to move towards the magnet 120, thereby detaching from the conductive strip 102. In this way, when the junction box 110 and the lamp body 200 move within the track 100, the conductive part 116 will not rub against the conductive strip 102.
[0044] It is worth noting that when the magnet 120 is driven to move downward, the operator pushes the lamp body 200 upward with one hand and pulls the pull ring 141 downward with the other hand. Therefore, the downward pulling force exerted on the track 100 when the magnet 120 is separated from the metal strip 101 will be canceled by the force exerted by the operator pushing the lamp body 200. This avoids applying a pulling force to the track 100 when the magnet 120 is separated from the metal strip 101, thus improving the stability of the connection between the track 100 and the building.
[0045] The foregoing has shown and described the basic principles, main features, and advantages of the present invention.
