[0037] Specifically, the first docking portion 11 is arranged along the outer edge of the rear end surface of the lamp holder 10 to form an enclosure, and the second docking portion 21 is arranged along the front end surface of the control box 20 to also form an enclosure. The outer wall of the enclosure on the control box 20 matches the inner wall size of the enclosure of the lamp holder 10, so that the second docking portion 21 on the control box 20 can be inserted into the first mounting cavity 111 of the lamp holder 10, and the second docking portion 21 and the first docking portion 11 are interference fit to achieve a detachable connection between the lamp holder 10 and the control box 20.

In addition, the conductive terminals can be separately arranged to ensure the independence of signal transmission and power supply to avoid mutual interference. Of course, the conductive terminals can be designed to be centralized to simplify the structure, reduce the number of connectors, and improve the connection efficiency.

[0045] See also Figure 2 and Figure 3 In some embodiments, a locking mechanism 40 is further provided on the lamp holder 10 , and the locking mechanism 40 can lock or unlock the lamp holder 10 and the control box 20 .

[0046] See also Figure 2 and Figure 3 The locking mechanism 40 is fixed on the rear end surface of the lamp holder 10 and is located in the first installation cavity 111 of the lamp holder 10. The first docking portion 11 of the lamp holder 10 is provided with a first through hole 43 corresponding to the locking mechanism 40; the second docking portion 21 of the control box 20 is provided with a locking groove 44, and the two ends of the locking groove 44 in the length direction are provided with second through holes 45 that connect the locking groove 44 with the outside. When the locking mechanism 40 is accommodated in the locking groove 44 and penetrates the first through hole 43 and the second through hole 45, the locking mechanism 40 fixes and locks the lamp holder 10 and the control box 20.

[0047] See also Figure 7 and Figure 8In some embodiments, the locking mechanism 40 includes a moving member 41 and an elastic member 42. The moving member 41 is arranged relative to the first through hole 43 and can slide along the extension direction of the first through hole 43, and the elastic member 42 abuts against the moving member 41. When the elastic member 42 elastically stretches, the abutting moving member 41 moves toward the direction of the first through hole 43, so that the moving member 41 passes through the second through hole 45 and the first through hole 43 to achieve locking.

[0048] Specifically, two moving members 41 are provided, and the two moving members 41 correspond to the two first through holes 43 respectively. Two elastic members 42 are also provided, and both elastic members 42 are compression springs. When the two moving members 41 are driven away from each other by the elastic members 42, the moving members 41 can be inserted into the first through hole 43 and the second through hole 45 to lock the lamp holder 10 and the control box 20 to each other; when the two moving members 41 are close to each other, the moving members 41 can be withdrawn from the first through hole 43 and the second through hole 45, and the lamp holder 10 and the control box 20 are unlocked.

[0049] See also Figure 8 In some embodiments, the moving member 41 includes a locking rod 411 and a push button 412.

The push button 412 is connected to the locking rod 411, and the push button 412 extends from the housing of the lamp holder 10 to the outside. When the push button 412 is pushed to compress the elastic member 42, the locking rod 411 withdraws from the first through hole 43 and the second through hole 45 to achieve unlocking.

[0050] Specifically, each moving member 41 includes a locking rod 411 for locking and a push button 412 for unlocking. The push button 412 is arranged in a notch on the end surface of the lamp holder 10 and abuts against the elastic member 42.

[0051] When the user pushes the two push buttons 412 inwards and brings the two push buttons 412 closer to each other, the two locking rods 411 also move closer to each other and exit the first through hole 43 on the lamp holder 10 and the second through hole 45 on the control box 20, so that the lamp holder 10 and the control box 20 can be separated from each other.

[0052] When the push force on the push button 412 is released, the elastic member 42 recovers its elastic deformation and stretches to press the locking rod 411 away from each other, so as to be inserted into the first through hole 43 and the second through hole 45, thereby locking the lamp holder 10 and the control box 20. The locking mechanism 40 is used to lock and unlock the lamp holder 10 and the control box 20, which can effectively improve the connection strength and reliability between the modules and enable them to be quickly fixed.
