[0041] AsFigure 5 As shown, after the first tongue cutter 20 is inserted from the part with a larger width of the installation groove 17, it moves along the surface of the bridge structure 16 to the part with a smaller width of the installation groove 17. Under the action of gravity, the first tongue cutter 20 closely adheres to the surface of the bracket end mounting plate 14 and is limited and locked by the bridge structure 16. It is required that the first tongue cutter 20 is provided with a neck with a smaller diameter, and the end of the neck is connected to a head with a larger diameter. The width of the head of the first tongue cutter 20 is smaller than the part with a larger width of the installation groove 17 and larger than the part with a smaller width of the installation groove 17. The width of the neck of the first tongue cutter 20 is smaller than the part with a smaller width of the installation groove 17 so that it can slide along the part with a smaller width of the installation groove 17.

[0043] In one embodiment, a bracket 2 is provided at each end of the mounting disc 3, and both ends of each bracket 2 are respectively connected to the ceiling-mounted film-covered back plate 4 through the left slide rail 1 and the right slide rail 5.

[0044] In one embodiment, a retaining edge is provided inside the profile frame 10 to limit the diffusion plate 12, and the diffusion plate 12 is made of a light-transmitting material.

[0045] Working principle:

[0046] First, assemble the left slide rail 1, right slide rail 5, ceiling-mounted film-covered back plate 4, drive box 6, drive 7, wire protection sleeve 8, wire fixing seat 9, profile frame 10, lighting module 11, and diffusion plate 12 into a complete lighting fixture. The bracket 2 and mounting plate 3 are pre-installed on the roof. Then, it is necessary to hoist the complete lighting fixture onto the bracket 2. During this process, since the bracket ends of the bracket 2 are provided with bracket end flanges 15, the left slide rail 1 and right slide rail 5 can be positioned simply by sliding them into the space between the bracket end flanges 15 on both sides respectively, without the need to align bolt holes as in traditional bolt-connected lighting fixtures. After the left and right positioning is completed, the first cutting tongue 20 can be inserted from the part with a larger width of the installation groove 17, and then slide the complete lighting fixture so that the first cutting tongue 20 slides from the part with a larger width of the installation groove 17 to the part with a smaller width. Since the complete lighting fixture is supported by manpower during installation, the first cutting tongue 20 can easily slide over the surface of the bridge structure 16 and finally reach the end space of the part with a smaller width. At this time, the second cutting tongue 21 just engages with the edge of the bracket end mounting plate 14. During this sliding process, the bracket end flanges 15 also play a guiding role for the left slide rail 1 and right slide rail 5, facilitating the sliding of the complete lighting fixture. Finally, after the manpower is removed, the first cutting tongue 20 is pressed against the surface of the bracket end mounting plate 14 under the action of gravity and the elastic force of the second cutting tongue 21, and the bridge structure 16 plays a limiting role for the first cutting tongue 20, realizing the locking of the complete lighting fixture. When it is necessary to remove the complete lighting fixture, only need to overcome the gravity and the elastic force of the second cutting tongue 21 by manpower, and move the first cutting tongue 20 in the reverse direction to the part with a larger width of the installation groove 17 to unload the complete lighting fixture.
