Description

[0002] Downlights are functional basic lighting used to provide uniform, comfortable, and soft illumination to meet people's basic needs for spatial brightness. A downlight consists of a frame and a rotating part. When the frame and rotating part are rotatably connected, and the wiring is directly connected to the rotating part, the wiring can become tangled and break, thus limiting the downlight's range of motion.

[0030] Furthermore, the sliding ring assembly 200 includes a first slip ring 210, a second slip ring 220, a sliding disk 230, and a conductive spring 240.

The second slip ring 220 is fixedly installed in the circular groove 2301. The first slip ring 210 is fixedly connected to the first housing 110 and is movably installed in the circular groove 2301. The first slip ring 210 and the second slip ring 220 elastically abut against each other. A gear portion 231 is provided circumferentially in the sliding disk 230. The rotation drive assembly 300 is fixed to the first housing 110, and the output gear of the rotation drive assembly 300 meshes with the gear portion 231.

[0031] In this embodiment, when the rotation drive assembly 300 is started, the output end of the rotation drive assembly 300 drives the gear part 231 of the sliding disk 230, so that the sliding disk 230 slides circumferentially relative to the second housing 120 in the mounting groove 101. The first slip ring 210 is installed in the annular groove 2301 and maintains elastic contact with the second slip ring 220, so that during the process of the second slip ring 220 rotating together with the sliding disk 230, the conductive spring connected to the first slip ring 210 and the second slip ring 220 maintain good electrical contact, and the first slip ring 210 and the second slip ring 220 maintain stable current transmission.
