[0032] refer to Figures 1-6 This embodiment provides a spliced ceiling lamp, which includes a lamp body 1, a light source board 2, and a driver board 3 disposed within the lamp body 1. An operating surface 11 for assembling the light source board 2 and the driver board 3 is provided within the lamp body 1. The driver board 3 is detachably assembled within the operating surface 11, and after the driver board 3 is assembled, the light source board 2 is further detachably assembled onto the driver board 3. By providing a detachable driver board 3 and light source board 2, the lamp can quickly and individually replace a damaged light source board 2 or a damaged driver module without the need for soldering wires or specialized tools for disassembly and assembly, greatly eliminating energy waste.

[0033] In this embodiment, the driving plate 3 is screwed into a slot 32 for installation or removal from the lamp body 1. Specifically, two slots 32 are circumferentially disposed on the driving plate 3, and two latching feet 13 are disposed within the operating surface 11 at positions corresponding to the two slots 32. The latching feet 13 can be inserted into the slots 32, and the driving plate 3 can rotate relative to the lamp body 1 within the length of the slots 32.

[0034] The slot 32 and the foot 13 are fixed by a rotational snap connection. The slot 32 has two slots of different widths. The foot 13 has a large end and a small end. One of the slots is sized to fit the large end of the foot 13, while the other slot fits the small end of the foot 13. The one slot is used to allow the foot 13 to be inserted into the slot 32. When the drive plate 3 is rotated from one slot toward the other slot, the small end of the foot 13 slides into the other slot, and the large end forms a stop, thereby achieving the locking of the drive plate 3 in the operating surface 11. When it needs to be removed, it only needs to be rotated in the opposite direction, and the foot 13 can be disengaged from one slot, and the drive plate 3 can be removed. This structure can achieve quick removal and installation of the drive plate 3, facilitating maintenance and replacement of the drive plate 3.

[0035] In this embodiment, the light source board 2 is inserted into or disassembled from the lamp body 1 in a manner of being pushed into the card slot 32. Specifically, the light source board 2 is divided into a plurality of light source modules 21 of equal size. Each light source module 21 is provided with a plug-in end 22. Correspondingly, a plug-in notch 31 is provided on the driving board 3. A plurality of plug-in notches 31 can be provided on the driving board 3. Different numbers of light source modules 21 are assembled according to the production and lighting requirements, such as Figure 1 or Figure 6 .

[0036] A plurality of plug-in notches 31 are equidistantly arranged along the circumferential direction on the edge of the driving board 3, and the plug-in notch 31 is set as a V-shaped or U-shaped opening. Correspondingly, the plug-in end 22 is set as a V-shaped or U-shaped end. The assembly between the driving board 3 and the light source module 21 through a specific shape can provide better stability and protection, which is simple and reliable.

[0037] The electrical connection between the light source module 21 and the driving board 3 is that by soldering a plurality of plug-in end sub-parts 22 on the driving board 3, they can be set as male terminals 33 or female terminals 24. By soldering a plurality of plug-in end sub-parts 22 on the light source module 21, they can be set as male terminals 33 or female terminals 24. By respectively providing male terminals 33 and female terminals 24 corresponding to the plug-in notch 31 and the plug-in end 22, the male terminals 33 and the female terminals 24 are used to cooperate to form an electrical connection. The electrical connection between the light source module 21 and the driving board 3 can also be realized through pins or other structures. Through the plug-in detachable connection design between the light source module 21 and the driving board 3, rapid connection, repair and replacement can be realized, and automated production can be carried out. Moreover, the shape and quantity of the light source module 21 in this design can be flexibly adjusted, so that the light source particles are evenly arranged at equal intervals within the light-emitting area, and the lamp emits light evenly without dazzling bright spots.

[0038] During the assembly process of the light source module 21 and the driving board 3, in order to make the structural splicing more stable, a limiting structure is provided between the light source module 21 and the operating surface 11 of the lamp body 1. The limiting structure includes a limiting notch 23 provided on the light source module 21 and a plurality of limiting points 12 provided at corresponding positions on the operating surface 11. When the light source module 21 is pushed into the driving board 3 for connection, the limiting notch 23 is inserted into the limiting points 12. By limiting the light source module 21, the circumferential rotation of the driving board 3 is restricted to stably install the driving board 3, and the limiting structure can further fix the light source module 21 on the lamp body 1.

[0039] In this embodiment, a V-shaped or U-shaped light source module 21 is provided. The light source module 21 includes a V-shaped or U-shaped bottom plate 25 and a light-emitting component disposed on the bottom plate 25. The light-emitting component includes light source particles. A number of light source particles are distributed on the bottom plate 25, and the light source particles are equidistantly arranged from adjacent light source particles. That is, the distribution of the light sources on the bottom plate 25 is uniform, and the uniform distribution of light can be achieved without the aid of additional components such as optical lenses, which can solve the problem of light spots caused by uneven arrangement of the light sources of traditional modular lamps.

[0040] The design of the V-shaped or U-shaped light source module 21 enables the panel production of the bottom plate 25, reducing costs.

[0041] The specific setting of the bottom plate 25 is that the closed end of the bottom plate 25 is a plug-in end 22, and limiting notches 23 are provided on both sides of the open end of the bottom plate 25. Correspondingly, a number of limiting points 12 are arranged at intervals along the circumferential direction in the operation surface 11, and two limiting points 12 are taken as a group, corresponding to the positions of the two limiting notches 23 on one bottom plate 25. The plurality of light source modules 21 are inserted at equal intervals along the circumferential direction on the edge of the driving plate 3.

[0042] Two long grooves 14 are symmetrically arranged on both sides of the limiting point 12, and an introduction ramp 26 is provided at the opening of the limiting notch 23. The introduction ramp 26 is arranged inside the opening. The introduction ramp 26 is used to introduce the limiting point 12. After the limiting point 12 is introduced, the two side edges of the limiting notch 23 are inserted into the long grooves 14 on both sides of the limiting point 12 to form clamping and limiting. The directional introduction is formed by the introduction ramps 26 on both sides, so that the light source module 21 can be well clamped between the limiting points 12 on both sides after being pushed in, forming a limiting fit.

[0043] The spliced ceiling lamp provided in this embodiment realizes quick installation and replacement without professional tools by setting the driving plate 3 and the light source plate 2 as detachable structures, combining the quick-connection terminal connection method with the quick-connection chute structure of the structural parts in a "building block" manner, enabling the implementation of energy reuse, saving energy, prolonging the service life of the lamp, and saving the usage cost of consumers. The light source plate 2 is divided into a number of light source modules 21. If the driving plate 3 or the light source module 21 is damaged, the damaged part can be directly replaced, and the shape and quantity of the light source module 21 can be flexibly adjusted, so that the light source particles are evenly arranged at equal intervals within the light-emitting area, and the lamp emits light evenly without dazzling bright spots, making the product emit light evenly without glare and improving the comfort of product use.

[0044] The above is only a preferred specific embodiment of the present invention, but the design concept of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention who makes non-substantive modifications to the present invention using this concept shall fall within the scope of infringement of the protection of the present invention.
