[0031] In some embodiments, as shown in Figure 1 Each second hinged shaft assembly 5b is located on a first virtual circle, and each third hinged shaft assembly 5c is located on a second virtual circle. The center of the first virtual circle and the center of the second virtual circle are respectively located on the central axis of the lamp holder 10, and the diameter of the first virtual circle is smaller than the diameter of the second virtual circle. In this way, the light emitted by the lamp body assembly can form a circular lighting area below the ceiling lamp. Specifically, when adjusting, the diameter of the first virtual circle and the diameter of the second virtual circle gradually increase with the outward expansion of the lamp body assembly, and the diameter of the first virtual circle and the diameter of the second virtual circle gradually decrease with the inward shrinkage of the lamp body assembly.

[0032] In some embodiments, as shown in Figures 1-9The first light-emitting lamp body 4a and the second light-emitting lamp body 4b are both in the shape of a long strip. In this way, the first light-emitting lamp body and the second light-emitting lamp body can be better rotated, and the lamp body assembly after combined installation can be more smoothly contracted or expanded.

[0033] In some specific embodiments, with reference to Figure 4 and Figure 5 The first light-emitting lamp body 4a and the second light-emitting lamp body 4b both include a light-shielding cover 41 and a light-transmitting cover 42 connected together, and an LED lamp strip 43 located between the light-shielding cover 41 and the light-transmitting cover 42. The side of the light-transmitting cover 42 close to the light-shielding cover 41 is recessed and provided with an embedded groove 421 for embedding and installing the LED lamp strip 43. Specifically, as an example, the light-transmitting cover is a plastic piece, and the light-shielding cover is an aluminum sheet. Through the cooperation of the light-shielding cover and the light-transmitting cover, the lamp body assembly can emit light towards the middle.

[0034] As a preferred embodiment, as shown in Figure 4 and Figure 5 The LED lamp strip 43 and the embedded groove 421 are both distributed along the length direction of the light-transmitting cover 42.
