Light source 112, the light baffle 16 is provided with a plurality of light-transmitting small holes 161 near the upper laser light source 111, and the light baffle 16 is provided with a semicircular light-transmitting large hole 162 near the lower laser light source 112; the upper laser light source 111 passes through the reflector 13, the mosaic reflective component 14, the light baffle light-transmitting small holes 161 and the glass component 15 in sequence, and the lower laser light source 112 passes through the reflector 13, the mosaic reflective component 14, the light baffle semicircular light-transmitting large hole 162 and the glass component 15 in sequence; the projection angles of the two laser light sources 11 presenting different effects are consistent, thereby jointly forming a more dreamy visual projection effect.

[0047] In this embodiment, the glass assembly 15 includes a diamond glass 151 and a glass plate 152 that transform a single light spot into complex and varied lines. The diamond glass 15 is arranged directly in front of the semicircular light-transmitting hole 162 , and the glass plate 152 is arranged in front of the diamond glass 151 .

[0048] In this embodiment, the upper laser light source 111 passes through the reflector 13, the mosaic reflective component 14, the light-blocking plate light-transmitting small hole 161 and the glass plate 152 in sequence, and the lower laser light source 112 passes through the reflector 13, the mosaic reflective component 14, the light-blocking plate semicircular light-transmitting large hole 162, the diamond glass 151 and the glass plate 152 in sequence, so that the projection angles of the two light sources presenting different effects are consistent.

[0049] In this embodiment, the mosaic reflective assembly 14 includes a mosaic reflector 141, a motor 142 and a motor bracket 143, and the motor 142 drives the mosaic reflector 141 to rotate. The light beam of the laser light source 11 changes its propagation direction through the reflector 13, and then changes a single laser beam into multiple laser beams through the mosaic reflector 141. The mosaic reflector 141 is driven by the motor 142 to rotate so that the multiple laser beams are transformed, so that the visual effect of many small light spots like the starry sky appears on the projection surface.

[0054] The working principle and use process of the utility model: This product is composed of a pair of laser light sources. The laser beam of the light source changes its propagation direction through a reflector, and then changes a single laser beam into multiple laser beams through a mosaic reflector. The mosaic reflector is driven by a motor to rotate to change the multiple laser beams, so that it appears on the projection surface as a visual effect of many small light spots like a starry sky. The multiple laser beams formed after reflection by the mosaic reflector pass through the diamond glass, turning a single light spot into complex and changeable lines, thus forming a more dreamy visual projection effect. The light output range is adjusted through the light baffle, so that the projection angles of the different effects presented by the two light sources are consistent, further improving the practicality of the lamp.
