The light effect switching device can control the first drive 500 to operate, so that the first white light hole 311 of the rotary pattern disc 300 coincides with the optical axis of the lamp, and the first drive 500 is locked, thereby ensuring that the first white light hole 311 keeps coinciding with the optical axis of the lamp, and the light beam is imaged at the point A.

If a standard light beam needs to be output, the second driver 600 operates to drive the second turntable 410 to rotate, so that the second white light hole 412 coincides with the light axis of the lamp, i.e. the first white light hole 311, the second white light hole 412, the light axis of the lamp and the light transmitting hole 110 are coaxially arranged. Under the limiting action of the second white light hole 412, the second white light hole 412 can block peripheral light beams with poor quality and stray light beams, so that effective light is converged and diverged at a light source focus, then the effective light passes through the first white light hole 311 and is collected by the focusing lens 700, and sharp light beams can be formed after zooming and amplifying are controlled by an optical system, and clear round light spots can be displayed on a projection surface.

If other pattern light beams are required to be output, the second driving unit 600 may drive the second turntable 410 to rotate, so that the pattern hole 413 coincides with the optical axis of the lamp, that is, the light hole 110, the first white light hole 311, the pattern hole 413 and the optical axis of the lamp are located on the same straight line, so as to form a beam of light matched with the pattern of the pattern hole 413, and display a clear pattern light spot on the projection surface.

If the fixed pattern light spot is required to be blurred, the focusing lens 700 can be driven to be far away from the rotary pattern disc 300 by linear driving, so that the pattern light spot is blurred, and the virtual shadow is not generated under the restriction of the pattern.

(2) When it is desired to output the beam effect of the rotating patterned disk 300. The light effect switching device can control the second driver 600 to operate, so that the light passing hole 411 of the fixed pattern disc 400 coincides with the optical axis of the lamp, and the second driver 600 is locked, thereby ensuring that the light passing hole 411 coincides with the optical axis of the lamp, and the light beam forms an image at the point B.

If a white light spot needs to be output, the first driver 500 operates to drive the first rotating disc 310 to revolve, so that the first white light hole 311 coincides with the optical axis of the lamp, i.e. the light transmitting hole 110, the first white light hole 311, the light passing hole 411 and the optical axis of the lamp are located on the same straight line. The light beam generated by the light source of the lamp passes through the light passing hole 411 of the fixed pattern disc 400 and is scattered again after the focus of the light source is converged, peripheral light beams with poor quality and stray light are blocked by the limitation of the first white light hole 311 of the rotating pattern, the effective light beam is collected by the focusing lens 700, after zooming and amplifying are controlled by an optical system, the imaging surface of the first white light hole 311 of the rotating pattern disc 300 is displayed on a projection surface, light spots with clear edges are displayed, and the illumination of the light spots is more uniform.

If other patterns need to be output, the first driving device 500 operates to drive the first rotating disc 310 to revolve, so that the rotating pattern 320 coincides with the optical axis of the lamp, i.e. the light hole 110, the rotating pattern 320, the light passing hole 411 and the optical axis of the lamp are located on the same straight line. The beam is limited by the pattern within the rotating pattern 320 and a clear spot of the corresponding pattern is displayed on the projection surface.

If the pattern rotation effect is required to be output, the first driver 500 operates to drive the corresponding rotation pattern 320 to rotate, so that the light spot on the projection surface has various rotation effects.

If the rotating pattern is required to be blurred, the linear driving control focusing lens 700 is far away from the rotating pattern disc 300, so that the pattern light spots are blurred, and the aperture of the light passing hole 411 is large enough to avoid affecting the limitation of the rotating pattern on the light beam, so that other ghosts are not generated.
