Description

Technical Field

[0001] The present application relates to the technical field of lighting equipment, and in particular to a magnetic conductive track and lighting equipment for magnetically adsorbing and electrically connecting electrical devices. Background Art

[0002] Track lights mainly include a track (conductive track) fixed on the ceiling or wall and various lamp bodies that can slide along the track, which can be spotlights, linear lights, etc.

[0003] like Figure 1 As shown, Figure 1 The schematic diagram of the structure of the low-voltage guide rail adopting the top power supply in the prior art is shown. The guide rail 91 includes a main body 911. The cross section of the main body 911 is roughly flat along the width direction of the guide rail 91. Two accommodating grooves 912 are recessed on the upper surface of the main body 911. The accommodating grooves 912 are arranged in parallel along the length direction of the guide rail 91. A coupling element 913 is arranged in each accommodating groove 912. The coupling element 913 is insulated from the main body 911. Each coupling element 913 includes a clamping member 9131. A conductive sheet 9132 is clamped in the clamping member 9131. A docking space 9133 capable of exposing the conductive sheet 9132 is provided on the upper surface of the clamping member 9131, thereby realizing the method of electrical docking and power supply at the top. Between the two accommodating grooves 912, the main body 911 is provided with an accommodating cavity 914 arranged along the length direction of the guide rail 91. A magnetic attraction component 915 is clamped in the accommodating cavity 914. The conductive sheet 9132 and the magnetic component 915 are both disposed horizontally and arranged in a left-center-right manner; the lamp is connected to the guide rail 91 in a face-to-face manner, the conductive part of the lamp penetrates into the docking space 9133 and docks with the conductive sheet 9132, and the magnetic part of the lamp is disposed face to face with the upper surface of the main body 911.

[0004] like Figure 2 As shown, Figure 2The schematic diagram of the structure of the low-voltage guide rail in the prior art adopting the inner side wall of the guide rail for power supply, the guide rail 92 includes a main body 921, and the cross section of the main body 921 is generally inverted U-shaped along the width direction of the guide rail 92. A magnetic attraction component 922 is clamped on the inner top surface of the main body 921. Similarly, since the magnetic attraction component 922 is located at the top of the guide rail 92, the magnetic attraction component 922 cannot directly contact the lamp body, so the adsorption force is weak. Receiving grooves 923 are respectively provided on the left and right inner side walls of the main body 92, and the receiving grooves 923 are arranged in parallel along the length direction of the guide rail 92. A coupling element 924 is arranged in each receiving groove 923, and the coupling element 924 is insulated from the main body 92. Each coupling element 924 includes a clamping member 9241, and a conductive member 9242 is clamped in the clamping member 9241. The conductive member 9242 is exposed on the left and right inner side walls of the main body 92, thereby realizing the power supply method of the inner side wall of the guide rail 92. The coupling element 924 and the magnetic component 922 are distributed in the same space, arranged up and down with a height difference. The magnetic component 922 is located above the inside of the space, and the conductive component 9242 is circular, which determines that the lamp is connected in a way of filling this space and has only one conductive loop.

[0005] It can be seen that the low-voltage magnetic guide rails commonly used in the market basically adopt a power-taking structure at the top or inside of the guide rail, combined with a magnetic component built into the slot at the top of the guide rail. The power-taking structure on both sides of the inside of the guide rail can achieve multi-channel control, but the form is relatively simple and cannot fully meet the diversified application needs of market products. This structure has few circuits, large single-channel current, high load power, and high heat; and the traditional adapter is installed inside the guide rail, and the wireless communication signal is weak.

[0069] like Figure 5As shown, in the embodiment of the present application, the installation body 10 includes two guide rail portions 12; the guide rail portion 12 is formed by vertically extending from the lower surface of the installation portion 11; the two guide rail portions 12 are spaced apart, and the first pair of coupling elements 201 and the second pair of coupling elements 202 are spaced apart on the guide rail portions 12 respectively; the first pair of coupling elements 201 are disposed opposite to each other in the horizontal direction or are disposed in parallel in the vertical direction on one of the guide rail portions 12; the second pair of coupling elements 202 are disposed opposite to each other in the horizontal direction or are disposed in parallel in the vertical direction on the other guide rail portion 12.

Figure 5 The first pair of coupling elements 201 and the second pair of coupling elements 202 shown in the figure can also be arranged side by side in the vertical direction on different rail parts; or the first pair of coupling elements 201 can be arranged opposite to each other in the horizontal direction on one rail part 12, and the second pair of coupling elements 202 can be arranged side by side in the vertical direction on the other rail part 12. Preferably, the coupling elements in the same pair are arranged opposite to each other in the horizontal direction.

[0070] The mounting body is provided with a first pair of conductive slots 1021 and a second pair of conductive slots 1022, respectively used to accommodate and fix the first pair of coupling elements 201 and the second pair of coupling elements 202. The first pair of conductive slots 1021 and the second pair of conductive slots 1022 are both convex-shaped, and the width of the slot opening is smaller than the width of the slot bottom.

[0071] In the embodiment of the present application, each of the coupling elements 20 includes an insulating portion 21 and a conductive portion 22; the insulating portion 21 is received in the conductive slots 1021 and 1022, and the insulating portion 21 is provided with a first space 112 and a second space 113 that are interconnected; the first space 112 is close to the bottom of the conductive slots 1021 and 1022, and the second space 113 is away from the bottom of the conductive slots 1021 and 1022 and faces outward; wherein the conductive portion 22 is received in the first space 112 and exposed in the second space 113, and is used to provide power to the lighting device. That is, the conductive portion 22 is received in the first space 112 of the insulating portion 21, and a portion of the conductive portion 22 is exposed at the corresponding second space 113, so that the conductor of the lamp body enters the second space 113 and is electrically connected to the conductive portion 22.

The conductive parts 22 are conductive copper foil or copper strips. The insulating part 21 can also be omitted when the installation body 10 is made of insulating material.
