The light emitted by the laser module 40 may transmit through the grating insert 62. When the grating insert 62 rotates, the light is adjusted by the grating insert 62, thereby adjusting the display effect of the laser lamp 100.

[0073] As shown in FIGS. 6, 11, 12 and 13, FIG. 12 is a structural schematic view of the insert tongue 61 shown in FIG. 11 according to some embodiments of the disclosure, and FIG. 13 is a cross-sectional structural schematic view of the grating-sheet insert module 60 along X-X direction shown in FIG. 11.

In some embodiments, the handle 612 may be omitted.

[0075] The insert tongue 61 may define a mounting hole 613 extending through the insert tongue 61 in the transmission path, and the mounting hole 613 is configured to mount the grating insert 62, so that the light emitted by the laser module 40 may enter the mounting hole 613 in the transmission path and transmit through the grating insert 62.

When the grating-sheet insert module 60 continues to slide, the elastic buckle 3321 bends in a direction of outside of the limit space 3301 and deforms elastically. When the grating-sheet insert module 60 continues to slide to enable the elastic buckle 3321 to rebound and enter the engaging groove 3321, the grating-sheet insert module 60 is engaged with the elastic buckle 3321, and the location of the grating-sheet insert module 60, such as the insert tongue 61, is limited by the elastic buckle 3321.

[0080] As shown in FIGS. 6, 11, and 13, the grating insert 62 may include a carrier 621 arranged in the mounting hole 613 and in contact and cooperating with and in transmission connection with the drive module 50, such as a transmission member 52, a grating sheet 622 arranged on the carrier 621, and a clamping member 623 cooperating with the carrier 621 to clamp and fix the grating sheet 622.

The grating sheet 622 has different portions or multiple same portions, each of the portions may be patterned. In some embodiments, the grating sheet 622 may not be divided into multiple portions, and may be integrally patterned. Even the grating sheet 622 may be configured based on the requirements of those skilled in the art for the display effect of the laser lamp 100, which is not limited. The light emitted by the laser module 40 may transmit through the grating sheet 622, that is, the light emitted by the laser module 40 may be transmitted into the mounting hole 613 in the transmission path and transmitted through the grating sheet 622. The carrier 621 is in contact with the drive module 50, such as the transmission member 52, so as to achieve transmission connection between the carrier 621 and the drive module 50, such as the transmission member 52. With the drive of the drive module 50, such as the transmission member 52, the carrier 621 may rotate around the shaft axis, and the grating insert 62, such as the grating sheet 622, may rotate.

[0107] The carrier plate 721 may be a plate-shaped structure or other structure configured to shield the light. The carrier plate 721 may define a mounting hole 7201 extending through the carrier plate 721 in the transmission path to mount the grating group 722. The number of the mounting holes 7201 may be equal to the number of the light-transmitting holes 321, and the mounting holes 7201 may correspond to the light-transmitting holes 321 one by one, so that the light transmitting through each of the light-transmitting holes 321 may transmit through a corresponding one of the mounting hole 7201.

[0108] The number of grating sub-sheets in the grating group 722 may be equal to the number of the mounting holes 7201, and each of the grating sub-sheets is arranged in a corresponding one of the mounting holes 7201. The light transmitting through the mounting hole 7201 may transmit through the grating group 722, such as the grating sub-sheets, thereby improving the display effect of the laser lamp 100 with cooperation of the grating-sheet insert module 60, such as the grating sheet 622.

[0109] It should be understood that when the carrier plate 721 is configured to shield the light, it may be replaced by a coating arranged on the protective sheet 71, so that the grating member 72 may be arranged on the protective sheet 71.

[0110] The fixing member 73 may be a sheet-shaped structure or other structure. The fixing member 73 may be arranged on a side of the grating member 72 away from the protective sheet 71 and may be fixedly connected to the housing cover 20, so as to cooperate with the housing cover 20 to clamp the protective sheet 71 and the grating member 72, so that the protective sheet 71 and the grating member 72 are arranged on the housing cover 20.

[0111] It should be understood that, in some embodiments, the fixing member 73 may be omitted, and the protective sheet 71 and/or the grating member 72 may be fixed to the housing cover 20 through bonding, welding, snapping, or the like.
