The bottom of the mounting plate 1311 is provided with a barb 1310. The fixing part 132 includes a spring 1321 and a fixing screw 1322. The fixing screw 1322 is inserted into the connecting post 1312 and passes through the connecting post 1312. The spring 1321 is sleeved on the part of the fixing screw 1322 that passes through the connecting post 1312. An abutment groove 11222 is also provided on the other wall of the second mounting slot 1122 at a position opposite to the through hole 11221. One end of the spring 1321 abuts against the mounting plate 1311, and the other end abuts against the abutment groove 11222. The spring 1321 provides elastic cushioning. When the base 1 is attached to the mounting plate 2, the position of the mounting plate 1311 can be adjusted by the extension and retraction of the spring 1321, so that the barb 1310 can be more smoothly engaged with the second hook part 23, while avoiding rigid contact that could damage the components.

[0045] For further details, please review. Figure 2 The top of the side wall 112 is provided with an annular groove 1123, and a sealing ring 11230 is provided inside the annular groove 1123. When the mask 4 is closed on the top of the side wall 112, the sealing ring 11230 is attached to the bottom of the mask 4. The sealing ring 11230 can enhance the sealing between the mask 4 and the base 1, prevent dust and moisture from entering the installation space 1111 and damaging the lighting assembly 3, thereby improving the protection performance of the ceiling light.

[0046] Furthermore, multiple retaining seats 1124 are provided along the periphery of the inner side of the side wall 112, and multiple rotating slots 41 are provided near the periphery of the bottom of the mask 4; when the mask 4 is closed on the top of the side wall 112, each retaining seat 1124 engages with a rotating slot 41. The cooperation between the retaining seat 1124 and the rotating slot 41 enables the mask 4 to be quickly fixed to the base 1 without screws, and the mask 4 can be installed and removed by hand.

[0047] Please refer to the following: Figure 7 As shown, Figure 7 This is a three-dimensional structural diagram of the face mask in the embodiment. The rotating slot 41 includes an insertion section 411 and a locking section 412; the locking section 412 extends from one end of the insertion section 411 along the periphery of the bottom of the face mask 4; when the face mask 4 is placed on the top of the side wall 112, rotating the face mask 4 or the base 1 causes the holder 1124 to extend into the insertion section 411 and rotate into the locking section 412. The insertion section 411 provides a quick-access channel for the holder 1124, while the locking section 412 securely limits the holder 1124, preventing the face mask 4 from accidentally falling off. The rotating operation simplifies the assembly and disassembly steps of the face mask 4.

[0048] Furthermore, the length of the mounting bracket 1124 is less than the length of the insertion section 411. This length design ensures that the mounting bracket 1124 can smoothly extend into the insertion section 411, avoiding jamming due to length mismatch and improving the ease of installation of the face mask 4.

[0049] For further details, please review. Figure 3 and Figure 5 The bottom wall 111 has a terminal block mounting compartment 1112 on its back.
