The quality LED Starry Sky Projection Lamp includes a casing, and the inner bottom of the casing is sequentially fixed with a main control board, a laser module, a motor, a light-emitting diode assembly and a square optical lens, and the motors are respectively connected with a transmission shaft through a linkage mechanism a and a transmission shaft b, the transmission shaft a is a hollow shaft, an optical element is fixedly connected to one end of the transmission shaft a, a lens is installed on the outer side wall of the casing, and a lens corresponding to the lens is arranged on the casing Installation port. In the present invention, the effect of star field arrangement is produced by the combination of laser modules and optical components, and the light emitted by light-emitting diode components is used to sequentially penetrate the square optical lens, the circular optical lens and the lens to generate cloud projection. , The sense of realism is stronger, and the projected nebula effect is better than the effect projected by the existing hollow lampshade, the nebula can move periodically, and the effect is closer to the real starry sky.

The above is a brief introduction to the relevant knowledge about quality LED Starry Sky Projection Lamp.
