The middle part of the lampshade shell 1 is a middle structure, the interior of the lampshade shell 1 is an inner cavity 11, the top cover 2 is covered at the top end of the lampshade shell 1, and the light source assembly 4 is arranged inside the inner cavity 11 through the top cover 2. Guard plates 5 are provided on both sides of the lampshade shell 1, and a horizontally arranged hanging rope 8 is provided in the middle of the guard plate 5. The hanging rope 8 is a long strip structure, the middle part of the hanging rope 8 is a spring part 81, and the two ends of the hanging rope 8 are hook rope parts 82. The hook rope part 82 is a hook-shaped structure with an opening opened inward, and the hook rope parts 82 at both ends can swing upward with the spring part 81 as the center.

[0024] Guard plates 5 are provided on both sides of the lampshade shell 1, and a long hanging rope member 8 is arranged in the middle of the guard plate 5. The hook rope parts 82 at both ends of the hanging rope member 8 can be firmly buckled on the keel of the ceiling. At the same time, the LED ceiling lamp is suspended in mid-air. The weight of the LED ceiling lamp itself can deform and bend the hook rope parts 82 at both ends upward along the spring part 81 as the center. The distance between the hook rope parts 82 at both ends can be shortened, and they are firmly buckled on the keel of the ceiling, which has good stability.

[0025] Specifically, such asFigure 5 As shown in the figure, an upwardly disposed insertion piece 51 is provided at the connection between the guard plate 5 and the hanging cable member 8. A reverse buckle 52 bent outward is provided in the middle of the insertion piece 51. The hanging cable member 8 is inserted into the middle of the insertion piece 51 through the spring portion 81, and the reverse buckle 52 extends to the outside of the spring portion 81 to form a structure for upper and lower limiting. When the LED ceiling lamp is in a suspended state, under the action of the self-gravity of the LED ceiling lamp, the guard plate 5 has a tendency to move downward. At the same time, it can be firmly buckled at the angle between the reverse buckle 52 and the insertion piece 51 through the spring portion 81, forming an effective limiting structure and having good connection stability.

[0026] Specifically, the connection structure between the top cover 2 and the lamp housing 1 is as Figure 4 shown. A plurality of connecting members 6 are provided between the top cover 2 and the lamp housing 1 for connection.
