[0030] The lighting assembly 2 includes a lamp body shell 21 sleeved on the outside of the guide rail shell 12, and a secondary coil 25 wound on the outside of the guide rail shell 12 is arranged in the lamp body shell 21. Specifically, the secondary coil 25 is wound in a hollow ring shape and sleeved on the outside of the guide rail shell 12 with the lamp body shell 21. The lamp body shell 21 is connected to a power conversion module 24, and the input end of the power conversion module 24 is electrically connected to the secondary coil 25, and the output end of the power conversion module 24 is electrically connected to the light source module 26. Specifically, the power conversion module 24 is used to convert the alternating current generated by the secondary coil 25 into direct current and collect the current of the light source module 26. The position of the secondary coil 25 corresponds to that of the primary coil 15 and forms an electromagnetic coupling;

The light source module 26 adopts LED lamp beads or lamp tubes and is arranged in the lampshade 27. The lampshade 27 can be positioned and installed through the side support 28 to form a cantilever lighting assembly 2.

[0036] In this embodiment, the guide rail shell 12 is vertically installed through the base 11, and the magnetic rod 14 and the primary coil 15 wound on the outer wall of the magnetic rod 14 are positioned and installed by the guide rail shell 12, and the guide rail shell 12 is sleeved with the lamp body shell 21, and the secondary coil 25 is positioned on the outside of the primary coil 15 by the lamp body shell 21, so that the primary coil 15 and the secondary coil 25 are correspondingly surrounded on the outside of the magnetic rod 14, and the power module 13 is used to pass alternating current to the primary coil 15, and the primary coil 15 generates a changing magnetic field, and the magnetic rod 14 of the same body guides the magnetic flux and increases the magnetic field of the secondary coil 25. The flux is transformed by the primary coil 15, the magnetic rod 14 and the secondary coil 25, and the power is supplied to the light source module 26 through the power conversion module 24, so as to form wireless power supply for the lighting component 2, avoiding the problems of complex lines and difficult maintenance brought by the traditional wired power supply method, and at the same time eliminating the exposed live contacts, reducing the risk of electric shock, and improving the safety of the lamp. The lighting component 2 is directly mounted on the guide rail component 1, without the need for complicated electrical connection operations, simplifying the process of installing and replacing the lamp body, improving the convenience of use, and having better waterproof and dustproof performance.

The ends of the two clamps 33 are connected with elastic members 35. The two clamps 33 clamp the guide rail shell 12 through the elastic members 35, and can be connected to the end of the lamp body shell 21 through the locking shell 31, connect the locking assembly 3 to the lighting assembly 2, and are coaxially sleeved on the guide rail shell 12, and the two clamps 33 are connected by the elastic member 35. The outer wall of the guide rail shell 12 is clamped by the clamp 33 to improve the stability of the lighting assembly 2 and prevent the lighting assembly 2 from sliding along the guide rail shell 12.

[0041] Among them, both ends of the clamp 33 are provided with locating pins 36, and both ends of the elastic member 35 are respectively connected to the locating pins 36 on the same side of the two clamps 33. Specifically, the elastic member 35 includes but is not limited to a non-metallic tension spring, an elastic rope, and a rubber ring. An arc-shaped groove 34 is opened on the adjacent side of the two clamps 33. The locating pin 36 passes through the groove 34, and the end of the elastic member 35 extends into the groove 34 and is connected with the locating pin 36. The clamp 33 and the elastic member 35 can be connected by the locating pin 36, which is more convenient for disassembly and maintenance.

[0042] Furthermore, the locking assembly 3 also includes two thrust blocks 37 annularly distributed in the clamping cavity 32, and the opposite ends of the two thrust blocks 37 extend outward from the locking shell 31. Specifically, the thrust blocks 37 are convex-shaped, and the outer wall of the locking shell 31 is provided with a through hole corresponding to the end of the thrust block 37. The thrust block 37 is slidably connected to the inner bottom surface of the clamping cavity 32. Specifically, the inner bottom surface of the clamping cavity 32 is provided with a guide groove 39, and the end of the thrust block 37 extending into the locking shell 31 sinks into the guide groove 39, and the thrust block 37 slides along the guide groove 39. The thrust block 37 connects and drives the two clamps 33 to move toward or away from each other. Specifically, the thrust block 37 is connected to the two clamps 33 and drives them to move toward or away from each other. One end of the force block 37 extending into the clamping cavity 32 is provided with a thrust surface 38 that contacts the end of the clamp 33, that is, both ends of the clamp 33 are provided with inclined thrust surfaces 38, and inclined thrust surfaces 38 are also provided on both sides of the end of the thrust block 37 located in the clamping cavity 32.

Specifically, the protruding end of the thrust block 37 is pressed, and the thrust block 37 moves into the clamping cavity 32 along the guide groove 39. After the two clamps 33 are opened by the thrust surface 38, the inner side wall of the limiting groove 313 abuts against the elastic member 35, and then the limiting groove 313 cooperates with the elastic member 35, and the elastic member 35 limits the pressing movement of the thrust block 37.

Therefore, by setting the positioning groove 312 on the outer side of the clamp 33, the positioning platform 311 cooperates with the positioning groove 312, so as to constrain the clamp 33 to prevent the clamp 33 from deflecting at a large angle in the clamping cavity 32, causing either end of the clamp 33 to detach from the thrust block 37, resulting in failure of the clamp 33.

[0045] Among them, a raised stop 310 is provided at one end of the guide groove 39 close to the guide rail shell 12, and a notch is formed at the end of one end face of the slot 34 to avoid movement interference, and the other end face contacts with the top of the stop 310.

[0046] In this embodiment, when the lamp body assembly 2 is installed, the thrust block 37 is pressed, and the thrust block 37 slides into the clamping cavity 32 and applies thrust to the two clamps 33 through the thrust surface 38, pushing the two clamps 33 to move away from each other, thereby stretching the elastic member 35 and opening the two clamps 33, and then the lamp body assembly 2 and the locking assembly 3 are sleeved on the guide rail housing 12 together, and the position and angle of the lamp body assembly 2 are adjusted;

[0047] Release the thrust block 37, and under the return action of the elastic member 35, the two clamps 33 move toward each other and clamp the guide rail shell 12, and push the two thrust blocks 38 to move away from each other through the thrust surface 38, and extend out of the locking shell 31, thereby locking the lamp body assembly 2, improving the stability of the lighting assembly 2, and preventing the lighting assembly 2 from sliding along the guide rail shell 12.
