[0029] See also Figure 1 , Figure 2 and Figure 3 The LED ceiling light provided by the utility model comprises a shell part 2, in which a light source assembly 1 and a driving device 4 are arranged, a lampshade 7 and a mesh cover part 5 are arranged above the shell part 2, the shell part 2 comprises a shell 21, a driving bracket 22, a heat sink bracket 23, a mounting plate 24 and a junction box body 26; the junction box body 26 is located on the side of the shell part 2, a wiring terminal and a junction box cover assembly 3 are arranged in the junction box body 26, the driving device 4 is located on the driving bracket 22, and the light source assembly 1 is located on the heat sink bracket 23. The mesh cover part 5 is arranged outside the lampshade 7, and a surface cover 8 and a lampshade sealing ring 10 are arranged between the mesh cover part 5 and the lampshade 7.

[0030] The LED cabin ceiling lamp provided by the utility model has a housing 21 made of 304 stainless steel plate through mold stretching, stamping, machining, spot welding and argon welding, which is light in weight and has higher corrosion resistance; a groove 41 is formed on the outer periphery of the driving device 4, and a wing matching the groove 41 is formed on the driving bracket 22, such as Figure 4 The driving bracket 22 adopts a wing structure, which is light and practical, and has a beautiful appearance; the mounting plate 24 adopts a rib structure, which has a stronger load-bearing capacity; the housing 21 and the rivet nut 25 are connected as a whole by rivet, which can reduce the deformation caused by the full weld nut.

[0031] The LED cabin ceiling light provided by the utility model adopts a metal cable waterproof connector 6 at the line inlet of the junction box body 26, which has strong versatility in disassembly, assembly and replacement, and the stretched junction box has a larger space and can be equipped with more types of wiring terminals, such as 3-way wiring terminals, Long Erx wiring terminals or Phoenix wiring terminals.

[0032] The LED ceiling light provided by the utility model adopts a specially designed junction box cover assembly 3, wherein the junction box cover assembly 3 includes a junction box cover 31, wherein a junction terminal bracket 32 ​​is provided inside the junction box cover 31, and a grounding plate 33 is provided on the junction terminal bracket 32. Since the junction terminal bracket 32 ​​has the grounding plate 33, when assembling the junction terminal, it is only necessary to insert the middle hole of the junction terminal into the grounding plate 33 of the junction terminal bracket, fix it to the junction terminal bracket 32 ​​with screws, and then lock the grounding plate 33, without connecting a grounding wire separately, so that the wiring inside the junction box is more convenient and the circuit is more concise and clear, such as Figure 5 shown.

[0034] The LED ceiling light in the embodiment of the utility model can be installed in a ceiling-mounted or wall-mounted manner, and the installation method is more flexible; the specific assembly is as follows:

[0035] The driving device 4 is installed inside the shell part 2 and fixed with screws. The input wire of the driving device 4 is covered with a PVC sleeve and passed through the wire hole into the junction box body 31. The output wire is connected to the light source assembly 1 through the connector 9, making it more convenient to disassemble and repair the light source assembly 1.

[0036] Apply a layer of thermal grease on the back of the heat sink on the light source assembly 1, and fix the light source assembly 1 to the heat sink bracket 23 of the shell component 2 with screws. The thermal grease layer helps to transfer the heat of the light source to the surface of the shell for heat dissipation and protect the LED lamp beads.

[0037] After the lampshade 7 is installed with the lampshade sealing ring 10, it is placed on the outside of the light source assembly 1, and then the top cover 8 and the mesh cover component 5 are put on the outside of the lampshade 7. The mesh cover component 5, the top cover 8, the lampshade sealing ring 10 and the lampshade 7 are fixed to the shell component 2 with screws, and the protection level reaches IP66.

[0038] Connect the aforementioned input wires to the wiring terminals respectively and tighten them, and use screws to fix the junction box cover assembly 3, the wiring terminals, and the junction box cover sealing gasket to the junction box position on the shell component to complete the assembly of the lamp body.

[0039] When using, the customer opens the junction box cover 32, passes the cable through the metal cable waterproof connector 6, and then connects it to the three corresponding wiring holes of the wiring terminals on the junction box cover 32 and locks it. After adjusting the cable to the required position, lock the metal cable waterproof connector 6 to prevent water from entering, and then fix the junction box cover assembly 3, the wiring terminals, and the junction box sealing gasket to the junction box body 31. The protection meets the IP66 requirements. This drawer-type junction box cover assembly structure is convenient for customers to connect outside the junction box without space restrictions, which improves the customer experience.
