Technical Field
[0001] This utility model relates to the field of laser technology, and in particular to a light output structure for a full-color laser. Background Technology
[0002] As an advanced laser device capable of emitting composite beams containing the three primary colors of red, green, and blue, full-color lasers are revolutionizing many fields with unprecedented force. Their unique technical characteristics and powerful functions make them a key element in achieving dazzling visual effects and high-precision operations.
[0003] In the field of laser beam light applications, traditional ordinary laser beam lights mostly adopt a single beam emission mode, which results in a relatively monotonous performance effect and is difficult to meet the demand for rich light and shadow presentation in diverse scenarios. Furthermore, the beam reflection component lacks flexibility in adjustment. Traditional reflectors are mostly fixed or manually adjusted, which cannot achieve dynamic linkage with the split beam and is difficult to adapt to multi-angle light output switching in complex scenarios. Therefore, this application proposes a light output structure for a full-color laser. Summary of the Invention
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a light output structure for a full-color laser to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a light-emitting structure for a full-color laser, comprising: a mounting plate with an opening at its center and an annular screw groove around the opening at the top of the mounting plate; a diffraction grating, a rotationally symmetric periodic structure, covering the opening at the top of the mounting plate; a protective cover covering the edge of the top of the diffraction grating and threadedly connected to the annular screw groove at the top of the mounting plate; a support assembly located at the top of the mounting plate, on which a rotary motor is mounted directly above the opening, the output end of the rotary motor passing through the support assembly, and a conical prism fixedly mounted at the output end of the rotary motor; a reflection assembly consisting of six sets arranged in a circular array at the edge of the top of the mounting plate; a full-color laser mounted at the center of the bottom of the mounting plate; and a beam emitted from the output end of the full-color laser and splitting through the opening and the diffraction grating.
[0006] Optionally, after the beam is split, it is refracted by a conical prism to the corresponding reflective component. The angle of the beam after being split and diffracted by the diffraction grating is 15°. The number of facets of the conical prism is the same as the number of reflective components, and the inclination of the facets of the conical prism is 30°. The split and diffracted beam propagates horizontally towards the reflective component after being refracted by the conical prism.
[0007] Optionally, the reflective assembly includes a flip bracket, a lens mounting base, and a reflector. The horizontal part at the bottom of the flip bracket is connected to the mounting plate by bolts. The vertical parts at both ends of the flip bracket are provided with shaft holes, and bearings are installed in both shaft holes. The lens mounting base is located between the flip brackets, and both ends of the lens mounting base are provided with rods inserted into the corresponding bearings. The reflector is detachably mounted on the lens mounting base, and a connecting plug is provided at the bottom of the reflector and the bottom of the lens mounting base.
[0008] Optionally, the connector includes a positioning block, a positioning rod, and a positioning bolt. Two positioning blocks are fixedly installed at the bottom of the lens mounting base. Each positioning block has a first through hole extending to the top of the lens mounting base at its bottom. Each positioning block has a second through hole on its side. Two positioning rods are fixedly installed at the bottom of the reflector and inserted into the first through holes. Each positioning rod has a third through hole on its side. The positioning bolt is inserted through the second through hole on the side of the positioning block and the third through hole on the side of the positioning rod.
[0009] Optionally, six sets of drive components are fixedly installed at the bottom edge of the mounting plate. A transmission component is provided between each set of drive components and the reflection component. Six notches are opened in a circular array at the edge of the mounting plate, and the six sets of transmission components are located in the corresponding notches.
[0010] Optionally, the drive assembly includes a motor bracket and a tilting motor, with the motor bracket fixedly mounted on the bottom of the mounting plate and the tilting motor mounted on the side of the motor bracket.
[0011] The transmission assembly includes two synchronous pulleys and a synchronous belt. The two synchronous pulleys are fixedly mounted on the shaft at the output end of the flip motor and at one end of the lens mounting seat in the reflector assembly, respectively. The synchronous belt drive is sleeved between the two synchronous pulleys.
[0012] Optionally, the support assembly includes a support plate and support rods. Insertion holes are provided at the top edge of the mounting plate and at two opposite notches. The support plate is located above the mounting plate. Support rods are fixedly installed at the bottom of both ends of the support plate. The bottom ends of the two support rods are inserted through into the corresponding insertion holes. Limiting plates that abut against the top of the mounting plate are fixedly installed at the bottom ends of the two support rods. Nuts that abut against the bottom of the mounting plate are threaded onto the bottom ends of the two support rods. The rotary motor is installed at the center of the top of the support plate.
[0013] Optionally, the top of the mounting plate and the area between the annular screw groove and the through-hole are provided with a plurality of semicircular grooves in a circular array, and the bottom edge of the diffraction grating is provided with a circular array of hemispheres in the same number as the semicircular grooves, with each hemisphere located in a corresponding semicircular groove.
[0014] The beneficial effects of this utility model are:
[0015] By emitting a composite beam containing the three primary colors of red, green, and blue from a full-color laser, and using a diffraction grating with a rotationally symmetric periodic structure to achieve precise beam splitting (the beam splitting diffraction angle is stable at 15°), the beams are then refracted by a conical prism (with a prism facet tilt of 30°) to form multiple horizontally propagating beams. Finally, through multi-angle reflection by six sets of reflective components, the limitations of traditional single-beam laser lights in performance are overcome. At the same time, the conical prism is rotated by a rotating motor, and the reflector angle is adjusted by a flipping motor (range of 5°-70°). The beam angle, color, and combination can be dynamically linked through programming to form a rich variety of laser patterns, meeting the needs of complex light and shadow effects in stage performances, landscape lighting, and other scenarios.
[0016] The reflective components achieve dynamic angle adjustment through drive and transmission components. Combined with the rotation control of the conical prism by the rotary motor, the direction and angle of the emitted beam can be precisely controlled. This solves the problem of "inability to dynamically link with the split beam" caused by the fixed or manually adjusted traditional reflectors. The six reflective components are arranged in a circular array. The matching design of the number of facets of the conical prism and the reflective components ensures that the split beam can be accurately guided to the corresponding reflector, realizing coordinated control of multi-directional light output and adapting to the multi-angle switching needs in different scenarios.
[0017] The diffraction grating adopts a rotationally symmetric periodic structure, which, together with the semicircular groove on the mounting plate and the positioning of the hemisphere at the bottom of the grating, ensures the structural stability during beam splitting. The inclination of the conical prism facet is precisely matched with the beam diffraction angle, ensuring that the beam after splitting propagates horizontally and stably to the reflecting component after refraction, reducing beam deflection or scattering, and improving the consistency of the beam splitting effect and the stability of the propagation path.

[0033] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0034] Please see Figures 1-7This utility model provides a technical solution: a light-emitting structure for a full-color laser, including a mounting plate 11, with an opening 12 at the center of the mounting plate 11, and an annular screw groove 13 around the opening 12 at the top of the mounting plate 11. A diffraction grating 15 with a rotationally symmetric periodic structure is covered at the opening 12 at the top of the mounting plate 11, and a protective cover 16 is provided at the top edge of the diffraction grating 15. The protective cover 16 is threaded into the annular screw groove 13 at the top of the mounting plate 11. A support assembly is provided at the top of the mounting plate 11, and a rotary motor 22 is mounted on the support assembly and directly above the opening 12. The output end of the rotary motor 22 passes through the support assembly, and a conical prism 2 is fixedly mounted at the output end of the rotary motor 22. 3. Six sets of reflective components 4 are installed in a circular array at the top edge of the mounting plate 11. A full-color laser 31 is installed at the center of the bottom of the mounting plate 11. The output end of the full-color laser 31 emits a beam 32. The beam 32 passes through the diffraction grating 15 through the port 12 to achieve beam splitting. The beam 32 emitted by the full-color laser 31 passes through the port 12 and the diffraction grating 15 with a rotational symmetry periodic structure to achieve beam splitting. Combined with the protective design of the protective cover 16 for the diffraction grating 15, it not only ensures the stability of the beam splitting effect, but also avoids damage to the grating from dust and external forces. At the same time, the layout of the support components and the six sets of circular array reflective components 4 provides a basic structural support for multi-directional light output and solves the problem of monotonous traditional light output effect.
[0035] like Figure 1 and Figure 3 As shown, after beam 32 is split, it is refracted by conical prism 23 to the corresponding reflective component 4. The angle of beam 32 after diffraction by diffraction grating 15 is 15°. The number of facets of conical prism 23 is the same as the number of reflective components 4, and the inclination of the facets of conical prism 23 is 30°. After being refracted by conical prism 23, the split diffracted beam 32 propagates horizontally towards reflective component 4. Through the specific structure inside diffraction grating 15 and the shape of conical prism 23, the angle parameters of beam splitting and refraction of beam 32 are defined (diffraction angle 15°, inclination of facets of conical prism 23 30°). The number of facets of conical prism 23 matches the number of reflective components 4, ensuring that the split beam 32 propagates horizontally and accurately to the corresponding reflective component 4 after being refracted by conical prism 23, thus improving the consistency and pointing accuracy of the beam 32 propagation path.
[0036] like Figure 1 , Figure 2 and Figure 6As shown, the reflective assembly 4 includes a flip bracket 41, a lens mounting base 43, and a reflector 44. The horizontal part at the bottom of the flip bracket 41 is connected to the mounting plate 11 by bolts. The vertical parts at both ends of the flip bracket 41 are provided with shaft holes, and bearings 42 are installed in both shaft holes. The lens mounting base 43 is located between the flip brackets 41, and both ends of the lens mounting base 43 are provided with rods that are inserted into the corresponding bearings 42. The reflector 44 is detachably mounted on the lens mounting base 43. A connecting plug 45 is provided at the bottom of the reflector 44 and the bottom of the lens mounting base 43. The reflective assembly 4 can flexibly flip the reflector 44, and the connecting plug 45 enables the detachable installation of the reflector 44.

The bottom of the reflector 44 has two positioning rods 452 that are inserted into the first through holes. The sides of each positioning rod 452 have a third through hole. The positioning bolt 453 is inserted through the second through hole on the side of the positioning block 451 and the third through hole on the side of the positioning rod 452. Through the cooperation of the positioning block 451, the positioning rod 452, and the positioning bolt 453, the connector 45 achieves precise positioning and quick assembly / disassembly of the reflector 44 and the lens mounting base 43, ensuring the consistency of the installation angle of the reflector 44, and facilitating subsequent cleaning, replacement, or calibration.
[0038] like Figure 1 and Figure 2 As shown, six sets of drive components 5 are fixedly installed at the bottom edge of the mounting plate 11. A transmission component 6 is provided between each set of drive components 5 and the reflective component 4. Six notches 17 are arranged in a circular array at the edge of the mounting plate 11. The six sets of transmission components 6 are located in the corresponding notches 17. The bottom of the mounting plate 11 has six sets of drive components 5, which are connected to the reflective component 4 through the transmission components 6 in the notches 17, forming a symmetrical and compact drive structure. This ensures the independent drive capability of each set of reflective components 4 and avoids interference problems caused by exposed transmission components 6, thereby improving the rationality of the system layout and the space utilization rate.
[0039] like Figure 1 , Figure 2 and Figure 6As shown, the drive assembly 5 includes a motor bracket 51 and a flip motor 52. The motor bracket 51 is fixedly mounted on the bottom of the mounting plate 11, and the flip motor 52 is mounted on the side of the motor bracket 51.
[0040] The transmission assembly 6 includes two synchronous pulleys 61 and a synchronous belt 62. The two synchronous pulleys 61 are respectively fixedly installed on the shaft at the output end of the flip motor 52 and one end of the lens mounting seat 43 in the reflector assembly 4. The synchronous belt 62 is sleeved between the two synchronous pulleys 61. The drive assembly 5 and the transmission assembly 6 adopt the combination of the flip motor 52, the synchronous pulleys 61 and the synchronous belt 62 to realize the smooth transmission and precise angle control of the reflector assembly 4. The synchronous belt 62 transmission has the characteristics of low noise and stable transmission ratio, ensuring the consistency of the flip angle of the reflector 44 and solving the problem of insufficient precision of traditional manual adjustment.
[0041] like Figure 3 and Figure 4 As shown, the support assembly includes a support plate 21 and support rods 24. Insertion holes 18 are provided at the top edge of the mounting plate 11, specifically at two opposite notches 17. The support plate 21 is located above the mounting plate 11. Support rods 24 are fixedly installed at the bottom of both ends of the support plate 21. The bottom ends of the two support rods 24 are inserted into the corresponding insertion holes 18. Limiting plates 25 are fixedly installed at the bottom ends of the two support rods 24, abutting against the top of the mounting plate 11. Nuts 26 are threaded onto the bottom ends of the two support rods 24, abutting against the bottom of the mounting plate 11. The rotary motor 22 is installed at the center of the top of the support plate 21. The support assembly, through the cooperation of the support rods 24, limiting plates 25, and nuts 26, achieves a firm connection between the support plate 21 and the mounting plate 11, ensuring the installation stability and coaxiality of the rotary motor 22 and the conical prism 23, reducing displacement caused by vibration, ensuring the accuracy of the refraction path of the beam 32, and improving the reliability of the system operation.
[0042] like Figure 4 and Figure 5 As shown, the top of the mounting plate 11, located between the annular screw groove 13 and the through-hole 12, has a plurality of semi-circular grooves 14 arranged in a circular array. The bottom edge of the diffraction grating 15 has a circular array of hemispheres 151, the same number as the semi-circular grooves 14, with each hemisphere 151 located in its corresponding semi-circular groove 14. The semi-circular grooves 14 of the mounting plate 11 and the hemispheres 151 at the bottom of the diffraction grating 15 form a positioning fit, ensuring the concentricity and levelness of the diffraction grating 15 during installation and improving the consistency of the beam splitting effect. At the same time, the threaded connection of the protective cover 16 further enhances the installation stability and protection of the diffraction grating 15 and extends the service life of the core optical components.
