As illustrated in FIG. 1, FIG. 1 is a schematically structural diagram of the low-voltage conductive track that supplies power from the top in the prior art. The conductive track 91 includes a main body portion 911. Along the widthwise direction of the conductive track 91, the cross section of the main body portion 911 is generally flat. Two accommodating slots 912 are recessed in the upper surface of the main body portion 911. The accommodating slots 912 are arranged in parallel along the lengthwise direction of the conductive track 91. A coupling element 913 is accommodated in each accommodating slot 912. The coupling element 913 is insulated from the main body portion 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 is provided on the upper surface of the clamping member 9131 to expose the conductive sheet 9132, so as to achieve electrical connection and power supply at the top. Between the two accommodating slots 912, the main body portion 911 is provided with an accommodating cavity 914 arranged along the lengthwise direction of the conductive track 91, and a magnetic component 915 is clamped in the accommodating cavity 914. However, because the magnetic component 915 is located at the top of the conductive track 91, the magnetic component 915 cannot directly contact the lamp body. The conductive sheet 9132 and the magnetic component 915 are both arranged laterally and arranged in a left-center-right manner, and the lamp is connected to the conductive track 91 in a face-to-face manner. The conductive part of the lamp is deeply docked into the docking space 9133 and connected with the conductive sheet 9132, and the magnetic part of the lamp is arranged face-to-face with the upper surface of the main body portion 911.

As illustrated in FIG. 2, FIG. 2 is a schematically structural diagram of the low-voltage conductive track that supplies power from the inner wall of the conductive track in the prior art. The conductive track 92 includes a main body portion 921 which is along the widthwise direction of the conductive track 92, the cross section of the main body portion 921 is substantially inverted U-shaped. A magnetic component 922 is clamped at the inner top surface of the main body portion 921. Similarly, because the magnetic component 922 is located at the top of the conductive track 92, the magnetic component 922 cannot directly contact the lamp body, so the absorption capacity is weak. Accommodating slots 923 are respectively provided at the left and right inner walls of the main body 921, and the accommodating slots 923 are arranged in parallel along the lengthwise direction of the conductive track 92, and a coupling element 924 is accommodated in each accommodating slot 923. The coupling element 924 is insulated from the main body portion 921, and each coupling element 924 includes a clamping member 9241, a conductive component 9242 is clamped inside the clamping member 9241, and the conductive component 9242 is exposed on the left and right inner walls of the main body portion 921, thereby realizing the power supply from the inner wall of the conductive track 92.

It can be seen that no matter whether the power is supplied from the top or the inner wall of the conductive track, the conductive sheet 9132 or the conductive component 9242 in the low-voltage conductive track is basically made of the copper strip, the aluminum substrate PCB (circuit board) or the resin PCB; for the copper strip conductive sheet, the insulation strip is needed for electrical isolation, and an iron plate is needed to be built into the back as magnetic components 915 and 922; for the aluminum substrate PCB or the resin PCB conductive sheet, an iron plate is also needed to be built into the back as magnetic components 915 and 922, so the overall design has many parts, and the assembly process is also complex.

In the example of the present disclosure, as illustrated in FIG. 10, FIG. 11, and FIG. 12, the second connecting side 1020 is provided with an anti-rotation slot 1200 and two attraction elements 30, the anti-rotation slot 1200 is recessed into the base 1, that is, the anti-rotation slot 1200 is recessed toward the direction away from the first connecting side 1010, and the anti-rotation slot 1200 is clamped with the convex rib 12 and prevents the shaking in the left-right direction to achieve a rotation-stop effect. The depth of the anti-rotation slot 1200 recessed into the second connecting side 1020 is greater than or equal to the height of the convex rib 12 protruding from the first connecting side 1010. The attraction elements 30 are arranged on two sides of the anti-rotation slot 1200 and faces the first connecting side 1010; the first connecting side 1010 and the second connecting side 1020 are abutted against each other, the convex rib 12 extends into the anti-rotation slot 1200, and the two attraction elements 30 extend into the first connection slot 101 and the second connection slot 102, respectively, and form a magnetic attraction with the conductive substrates.

Because the attraction element 30 is arranged around the elastic electrical contact 311, the attraction element 30 also has the function of protecting the elastic electrical contact 311.

In order to improve the anti-rotation effect of the anti-rotation slot 1200, the proportional relationship between the extension depth and width of the anti-rotation slot 1200 is designed as follows: when the lighting device 400 shakes in the left-right direction on the magnetic conductive track 100, before the elastic electrical contact 311 at one side is detached from the conductive substrate 20, the anti-rotation slot 1200 abuts against the convex rib 12, thereby preventing the lighting device 400 from continuing to rotate.

The elastic electrical contact 311 is connected to the lighting device 400 through the wire 6, thereby enabling an external drive power source to supply power to the lighting device 400 through the magnetic conductive track 100.

In the present example, the base 1 includes an upper base 1021 and a lower base 1022; the upper base 1021 is the upper surface of the base 1, and the lower base 1022 is the lower surface of the base 1; the upper base 1021 is provided with the anti-rotation slot 1200 and the attraction element 30; the anti-rotation slot 1200 is arranged between two adjacent attraction elements 30; the lower base 1022 is mounted directly below the upper base 1021.

In the present example, the two sides of the upper base 1021 are respectively provided with a baffle 1211; the upper end of the lower base 1022 is provided with a clamping slot 1221, and the lower base 1022 is clamped between the two baffles 1211 of the upper base 1021 by the clamping slot 1221. The cross-section of the upper base 1021 and the lower base 1022 is in the shape of a square after the upper base 1021 and the lower base 1022 are fastened together, and an operation cavity for mounting the lamp body 2 is formed between the upper base 1021 and the lower base 1022.

As illustrated in FIG. 11, in the present example, the lower surface of the base 1 is provided with a through hole (corresponding to the position of the connecting rod 3 below the nut 4); one end of the connecting rod 3 passes through the through hole and is fastened on the lower surface of the base 1 by a nut 4; the lamp body 2 is connected with the other end of the connecting rod 3.

As illustrated in FIG. 11, in the present example, a gasket 5 is also arranged between the nut 4 and the lower surface of the base 1, and the outer diameter of the gasket 5 is larger than the outer diameter of the through hole. The nut 4 is screwed tightly with the connecting rod 3, and is used to fasten the connecting rod 3 to the through hole of the base 1. The gasket 5 can increase the contact area and strengthen the fastening between the nut 4 and the connecting rod 3, and a through hole is provided in the center of the connecting rod 3 and the nut 4 for the passing of the wire 6, thereby enabling the elastic electrical contact 311 to be electrically connected to the lamp body 2 through the wire 6.
