Background The ceiling embedded lamps in the current market are mainly divided into fixed type and manual adjusting type. The manual adjustment type lamp allows adjustment of the spot position, but needs manual ascending operation, so that potential safety hazards exist, the process is complex and time-consuming, and the efficiency is low. In addition, the light spot direction of the part of electric adjustment embedded lamp is changed by driving the lamp cap to rotate through the motor. Although the lamp provides an electric control function, the lamp cap can be obviously deviated in adjustment, so that dust is easy to accumulate on the protruding ceiling part of the lamp and the lamp cap is difficult to clean. Meanwhile, the optical system lacks independence, and accurate and independent spot position control cannot be realized. In addition, the deviation of the projection angle also causes the shape of the light spot to be deformed, and the illumination uniformity is destroyed. Chinese patent publication No. CN217441551U discloses a down lamp and a lighting system, which adopts the scheme that the size of the light spot is freely controlled by using an angle adjusting member and a liquid crystal zoom lens module. However, although the light spot size can be adjusted by the design, the adaptive adjustment cannot be performed according to the change of the projection angle. Therefore, how to electrically adjust the position and the size of the light spot while ensuring that the orientation of the lamp cap is kept constant is a current problem to be solved.
