[0026] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings:

[0027] Referring to Figures 1-5 , the placing grooves 4 are arranged on the aluminum substrate body 1, the lamp beads 2 are arranged in the placing grooves 4, and the matching dustproof frame 3 is arranged in the placing groove 4, so that dust is prevented from entering the connection between the lamp beads 2 and the aluminum substrate body 1.

[0028] The limiting assembly 6 includes a limiting rod 8. The dustproof frame 3 is provided with uniformly distributed mounting grooves 9 at the outer side. The limiting rod 8 is slidingly arranged in the mounting groove 9. The limiting rod 8 is fixedly provided with a compression spring 10 at the inner side.

[0032] Firstly, the dustproof frame 3 is placed on the placing groove 4, the limiting rod 8 outside the dustproof frame 3 is extruded into the mounting groove 9 by the placing groove 4, and the dustproof frame 3 can be pressed into the placing groove 4 by pressing the dustproof frame 3;

[0033] Then, the dustproof frame 3 is rotated, at this time, the limiting rod 8 reaches the horizontal section of the track groove 12, under the action of the compression spring 10, the limiting rod 8 abuts against the track groove 12, with the continuous rotation of the dustproof frame 3, the limiting rod 8 moves to the limiting groove 11, at this time, under the action of the compression spring 10, the end of the limiting rod 8 is embedded in the limiting groove 11, so that the dustproof frame 3 is limited in the placing groove 4, at this time, the lamp bead 2 is located in the dustproof frame 3, and the light emitted by the lamp bead 2 is emitted to the outside through the dustproof transparent plate 5;

[0034] When it is necessary to disassemble the dustproof frame 3, the dustproof frame 3 is reversely rotated, at this time, the spherical end of the limiting rod 8 slides out of the limiting groove 11 and enters the horizontal section of the track groove 12, then the dustproof frame 3 is continuously rotated, the limiting rod 8 moves to the turning part of the track groove 12, under the guidance of the turning part of the track groove 12, the limiting rod 8 moves to the vertical section of the track groove 12, in the process, the limiting rod 8 drives the dustproof frame 3 to move upward in the placing groove 4, and the upper end of the dustproof frame 3 is protruded from the placing groove 4, at this time, the worker holds the upper end of the dustproof frame 3, and the dustproof frame 3 is pulled out through the guide surface 13, when the limiting rod 8 moves to the guide surface 13, under the action of the guide surface 13, the limiting rod 8 is gradually pressed into the mounting groove 9.
