[0036] Further, the second driving assembly 9 includes: a second driving motor 91, a driving gear 92, a transmission belt 93, and a driven gear 94; the driven gear 94 is rotatably disposed on the turntable 4 and is meshed and connected with the first gear 51; the second driving motor 91 is disposed on one side of the first mounting bracket 12 away from the turntable 4; the output end of the driving motor passes through the first mounting bracket 12 and is in transmission connection with the driving gear 92; the transmission belt 93 is wound around the driving gear 92 and the driven gear 94; the driving gear 92 is in transmission connection with the driven gear 94 through the transmission belt 93.

In this embodiment, an MCU is selected.

[0050] In the specific implementation process, after installing the slide to be projected on the snap ring 5 on the turntable 4 and connecting and installing it, use the bracket 2 on the projection lamp to install the projection lamp at a suitable position such as a wall or a ceiling, then turn on the light source 3 built in the projection lamp, and adjust the stretching length of the outer lens barrel 71 to make the distance between the first imaging lens 72 and the second imaging lens 73, so as to achieve a suitable focusing degree, and then complete the installation;

[0051] When it is necessary to switch different light slides: Start the first drive motor 81. When the first drive motor 81 rotates, it will drive the turntable 4 on the output end to rotate. When the turntable 4 rotates, different light slides will be replaced onto the optical path to achieve the effect of replacing the light slides and projecting different patterns.

[0052] When it is necessary to adjust the angle of the projected picture or make it rotate continuously: Start the second drive motor 91. When the second drive motor 91 rotates, it will drive the driving gear 92 on the output end to rotate. During the rotation of the driving gear 92, the transmission belt 93 on the driving gear 92 will be driven to move, so that the driven gear 94 rotates. The driven gear 94 is meshed and connected with the first gear 51 on the outer periphery of the snap ring 5. When the driven gear 94 rotates, the snap ring 5 will rotate, so that the light slide installed in the snap ring 5 rotates, thus achieving the effect of adjusting the angle of the projected picture.
