What you don't know about LED Starry Sky Projection Lamp in china

The mirror array is pasted on a curved structure to form a curved reflective surface, the opening of the curved reflective surface is circular, and the curved reflective surface is inclined relative to the optical axis. The beam passes through the beam splitting unit to form two sub-beams, which are projected onto the mirror array The light spot on the beam splitting unit is adapted to the inclined curved reflective surface. By setting the two mirrors in the beam splitting unit to be non-coplanar, the light spot reflected by the two mirrors is partially overlapped, so as to project the light spot on the mirror array.
