Small panel lights usually have compact sizes and various designs, which can be round, square or rectangular to suit different decoration styles and space requirements.

[0003] Some advanced small panel lights can also have a dimming function, allowing users to adjust the brightness as needed. A Chinese utility model patent with application number 202122152512.8 discloses an intelligent voice-controlled dimming and color-adjusting panel light, in which an infrared sensor is arranged in the middle of the outer end surface of the panel light, a wiring head connected to the infrared sensor is arranged inside the panel light, and a through hole for the wiring head to pass through is opened in the middle of the diffusion plate, light guide plate, reflective paper and bottom cover in the panel light.

[0004] The above solution sets the sensor in the middle of the light-emitting surface of the panel light. Firstly, it will cause a dark area in the middle of the light-emitting surface. Secondly, through holes for the wiring heads to pass through need to be opened on the diffusion plate, light guide plate, reflective paper and bottom cover, which increases the difficulty of processing and assembly.
