As shown in
A plurality of clamping pieces 11 is arranged in the middle of the bottom end of the ceiling plate 10. The plurality of clamping pieces 11 enclose each other to form a clamping structure; the LED module is clamped into the clamping structure; the LED module is set as a corresponding polygonal structure in conjunction with the number of the clamping pieces 11. In the present embodiment, there are four clamping pieces 11, and the four clamping pieces 11 are uniformly distributed on the ceiling plate 10. Each clamping piece 11 is L-shaped and comprises a vertical connecting part 111 and a transverse limiting part 112. The limiting parts 112 of the plurality of clamping pieces 11 extend respectively towards a center direction of the ceiling plate 10. An inside surface of each connecting part 111 is arc-shaped. Two retaining pieces 12 are also arranged on the ceiling plate 10, are disposed oppositely and are arranged between every two adjacent clamping pieces 11 respectively. In addition, the ceiling plate 10 is further provided with a fool-proof point 13. In the invention, the fool-proof point 13 is a position where a ground wire screw is mounted. In addition, the ground wire screw may further be arranged between the two clamping pieces 11 and used for substituting one of the limiting pieces 12.
In the invention, the LED substrate 20 is quadrilateral. It may be understood that the LED substrate 20 may also be set as other shapes in other embodiments. Three of the corner positions of the LED substrate 20 are respectively provided with a mounting hole 21, and the remaining corner position is provided with a fool-proof opening 22; the fool-proof opening 22 corresponds to the fool-proof point 13 on the ceiling plate 10. It may be understood that the mounting hole 21 may also be formed in any other position of the LED substrate 20. The lampshade 30 comprises a bottom plate 31 and a raised part 32 arranged on the bottom surface of the bottom plate 31, and the bottom plate 31 is quadrilateral. The raised part 32 is arranged in the middle of the bottom plate 31, the top surface of the bottom plate 31 is provided with a plurality of bulges 33, and the bulges 33 are in one-to-one correspondence to the mounting holes 21 in the LED substrate 20.
A side length of the LED substrate 20 and a side length of the bottom plate 31 of the lampshade 30 are respectively smaller than a distance between the tail ends of the limiting parts 112 of the two opposite clamping pieces 11, such that the LED substrate and the lampshade 30 may be clamped into the clamping structure smoothly. A length of a diagonal line of the bottom plate 31 or the bottom 31 and the LED substrate 20 is larger than the distance between the tail ends of the limiting parts 112 of two opposite clamping pieces 11, and smaller than a distance between connecting parts 111 of two opposite clamping pieces 11. Therefore, the LED substrate 20 and the lampshade 30 may be rotatably clamped and limited into the clamping pieces 11.

The four clamping blocks 41 defines a quadrangle, and inside surfaces of the two clamping blocks 41 which are arranged diagonally are parallel. A distance between the inside surfaces of the two opposite clamping blocks 41 is equal to a side length of the LED substrate 20 and a side length of the bottom plate 31 of the lampshade, or equal to a length of a larger side of the LED substrate 20 and the bottom plate 31 of the lampshade.
During mounting, the bulges 33 on the lampshade 30 are clamped into the mounting holes 21 in the LED substrate 20, such that the lampshade 30 and the LED substrate 20 form a whole; and corners and sides of the combined lampshade 31 and LED substrate 20 are aligned to each other; then, the combined lampshade 30 and LED substrate 20 are mounted into the clamping structure; later, the four clamping blocks 41 of the mounting jig 40 are clamped to the outer sides of four sides of the bottom plate 31 and the LED substrate 20; and finally, the mounting jig 40 is rotated to drive the LED substrate 20 and the lampshade 30 to rotate till the LED substrate 20 and the lampshade 30 are rotated to one side of the retaining pieces 12; at this moment, the fool-proof opening 22 corresponds to the fool-proof point 13.
