The connecting bracket 21 includes a connecting plate 211 parallel to the back side of the lamp body 1. The connecting plate 211 is provided with a U-shaped opening; a hanging rod nut 221 is provided at one end of the hanging rod 22 close to the connecting bracket 21. The hanging rod 22 passes through the U-shaped opening, and the hanging rod nut 221 abuts against the edge of the U-shaped opening.

[0030] From the above description, it can be seen that the beneficial effect of the utility model is that: during assembly, it is only necessary to match the connecting plate 211 of the connecting bracket 21 with the hanging rod 22 fixed on the ceiling, and press the hanging rod 22 into the U-shaped opening of the connecting plate 211 to determine the installation position of the lamp body 1, and then use the hanging rod nut 221 to abut against the edge of the U-shaped opening, so that the lamp body 1 can be hung on the hanging rod 22, which can be installed conveniently and quickly without the need for traditional multi-accessory locking construction.

[0031] Furthermore, the suspension rod nut 221 is movable along the length direction of the suspension rod 22 .

[0032] As can be seen from the above description, the hanging height of the lamp body 1 can be adjusted by adjusting the position of the suspension rod nut 221 on the suspension rod 22. Specifically, the suspension rod 22 can be designed with a thread having a certain adjustable length to move with the suspension rod nut 221.

[0033] Furthermore, the connecting bracket 21 also includes a guide plate 212, which is obliquely connected to one side of the connecting plate 211, and the guide plate 212 is inclined toward the direction opposite to the U-shaped opening; a guide opening is provided on the guide plate 212, and the guide opening is connected to the U-shaped opening; inclined edges are provided on both sides of the guide opening away from the connecting plate 211.

[0034] From the above description, it can be seen that when the connecting bracket 21 is matched with the suspension rod 22, the inclined edge design of the guide opening of the guide plate 212 can be used to guide the suspension rod 22 along its inclined edge and slide into the U-shaped opening. In addition, the inclined design of the guide plate 212 also plays a guiding role. After the suspension rod 22 is pressed into the guide opening, the lamp body 1 is smoothly moved downward, so that the suspension rod 22 can move along the inclined direction of the guide plate 212 and finally slide into the U-shaped opening, which is convenient and quick to install.
