DETAILED DESCRIPTION

[0041] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] The embodiment of the present application provides a method for controlling the color of stage lights, thereby solving the problem that large-scale stage lighting devices in the prior art have powerful performance and high lighting complexity, but are not suitable for use on small stages or concert halls. Such stage devices are often complex in structure, high in processing and manufacturing costs, large in size, difficult to install, and require complex electrical control design in conjunction with precise mechanical design. The use of a complete system is expensive, and in some small stages and small concert halls, the budget is low and it is not convenient to use, while the low-cost purchased equipment cannot meet the needs of complex lighting effects.

[0043] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0044] The embodiment of the present invention discloses a method for controlling the color of stage lighting. Figure 1-13 As shown, the control method includes the following steps: Step S1: installing the lighting device at a target position;

[0045] Step S2: Install a suitable prism 6 on the light path of the lighting device;

[0046] Step S3: Control the near and far motion state of the prism 6 to adjust the light color range to change;

[0047] Step S4: controlling the deflection motion state of the polygon mirror 6 to further produce a color range change;

[0048] Step S5: Control the movement speed and the stop position of the polygon mirror 6 to achieve multi-form color change control of the stage lighting device at the target position;

[0049] When the above steps are used to adjust the light color, a lighting device is also specifically involved. The lighting device includes an assembly positioning bracket 1 and an inner carrier 11 arranged on the assembly positioning bracket 1. The inner carrier 11 is provided with a light host 2, and the light host 2 is provided with a light head 21;

[0050] The inner bearing frame 11 is connected with a positioning lampshade 3, on which a movable lampshade 4 is sleeved, on which a sleeve seat 5 is rotatably connected, and on which a multi-prism 6 is movably clamped;

[0051] The inner carrier frame 11 is provided with a control unit 7 for driving the movable lampshade 4 to move, and the movable lampshade 4 is provided with a deflection unit 8 for driving the sleeve 5 to move. The deflection unit 8 includes a transmission gear 81 arranged on the sleeve 5 and a base 82 arranged on the positioning lampshade 3, and the base 82 is provided with a rack 83 meshing with the transmission gear 81.

[0052] The method for controlling the color of stage lighting adopts a mechanical structure for controlling the color of lighting. The structural design has a sufficient safety factor and good durability, ensuring the stability of the overall control process. The position and angle of the prism 6 can be flexibly adjusted, so that the lighting range, dispersion angle and light transmittance of the lamp can be adjusted to meet the needs of different performance scenes.

[0053] The control unit 7 includes a fixed shaft 71 fixedly connected to the movable lampshade 4 and a connecting rod 72 sleeved on the fixed shaft 71. The connecting rod 72 is rotatably connected to an eccentric shaft 73 at one end away from the fixed shaft 71. A turntable 74 is fixedly connected to the eccentric shaft 73. A driving assembly 75 for driving the turntable 74 to rotate is provided on the inner carrier 11. The driving assembly 75 includes a driving motor 751 fixedly connected to the inner carrier 11 and a worm 752 fixedly connected to the output end of the driving motor 751. A worm wheel 753 is rotatably connected to the inner carrier 11. The worm wheel 753 meshes with the worm 752. The rotating shaft of the worm wheel 753 is fixedly connected to the eccentric shaft 73.

[0054] The control unit 7 in the device has a compact structure and stable operation. The control unit 7 is convenient for driving the movable lampshade 4 to move, and the movement of the movable lampshade 4 is used to drive the prism 6 to move, so that the distance between the prism 6 and the light head 21 changes, and the light path and dispersion effect are adjusted. At the same time, when the control unit 7 drives the movable lampshade 4 to move, it synchronously drives the deflection unit 8 to operate, and uses the deflection unit 8 to drive the prism 6 to deflect, thereby realizing a large range of dispersion transformation and multi-type light projection transformation effects, thereby enhancing the on-site stage lighting atmosphere.

[0055] The control unit 7 adopts a driving assembly 75 to provide power. When the driving motor 751 is working, it drives the worm 752 to rotate, the worm 752 drives the worm wheel 753 to rotate, the worm wheel 753 drives the turntable 74 to move, the turntable 74 drives the eccentric shaft 73 to move, the eccentric shaft 73 drives the connecting rod 72 to move, the connecting rod 72 drives the fixed shaft 71 to move, the fixed shaft 71 drives the movable lampshade 4 to move, the movable lampshade 4 drives the sleeve 5 and the prism 6 to move as a whole, so as to adjust the distance between the prism 6 and the light head 21, thereby adjusting the scattering of the light and changing different light spot sizes;

[0056] At the same time, when the movable lampshade 4 moves, the movable lampshade 4 synchronously drives the sleeve 5 and the transmission gear 81 to move. Since the transmission gear 81 is meshed with the rack 83 and the rack 83 is in a stationary state, the transmission gear 81 rotates, and the transmission gear 81 drives the sleeve 5 to rotate, and the sleeve 5 drives the prism 6 to rotate, so as to realize the self-rotation of the prism 6. When the prism 6 rotates, the refractive index of the prism 6 will change. Different refractive indices will also bring different colors to the light, and then the light emitted by the light head 21 is deflected and dynamically scattered through the self-rotation of the prism 6.

[0057] An embedding groove 51 is provided inside the sleeve 5, and an insert block 61 is fixedly connected to the prism 6. The insert block 61 is movably inserted in the embedding groove 51. A locking assembly 9 for locking the position of the insert block 61 is provided on the sleeve 5. The design of the embedding groove 51 and the insert block 61 makes it easy to quickly install and disassemble the prism 6, so that it is easy to replace the prism 6 later. Different prisms 6 have different light divergence effects. Therefore, the prism 6 is easy to replace, so that the projection effect of the stage light is easy to be further adjusted, thereby meeting different stage requirements.

[0058] The locking assembly 9 includes a limit groove 91 formed on the sleeve 5, a rotating rod 92 is rotatably connected inside the limit groove 91, a locking head 93 is provided on the rotating rod 92, a spring 94 is fixedly connected between the rotating rod 92 and the limit groove 91, a locking groove 62 is formed on the insert block 61, and the locking head 93 is movably engaged in the locking groove 62;

[0059] The locking assembly 9 has a simple structure and is easy to operate. When the prism 6 needs to be installed, the rotating rod 92 is first pressed to make the rotating rod 92 rotate and drive the locking head 93 to tilt up. At the same time, the rotating rod 92 squeezes the spring 94, and the plug block 61 is aligned with the inside of the embedding groove 51 and inserted. When the plug block 61 is fully inserted into the embedding groove 51, the rotating rod 92 is released, the spring 94 resets and pushes the rotating rod 92 to rotate, so that the rotating rod 92 drives the locking head 93 to move, and the locking head 93 is clamped in the inside of the locking groove 62, thereby realizing the rapid fixation of the plug block 61 and the prism 6.

[0060] A square slot 43 is provided at the bottom of the movable lampshade 4, and a cover 44 is movably connected to the square slot 43. The design of the square slot 43 and the cover 44 facilitates the rapid installation of the prism 6, so that the prism 6 and the insert 61 pass through the movable lampshade 4 and enter the bottom of the sleeve 5 during installation, and the cover 44 facilitates the sealing of the square slot 43.

[0061] The positioning lampshade 3 is provided with a lower groove 33 and an upper groove 32 . The lower groove 33 is designed so that the positioning lampshade 3 does not block the other notch 43 , and the upper groove 32 is designed so that the positioning lampshade 3 does not collide with the socket 5 .

[0062] A slide groove 31 is provided on the positioning lampshade 3, and a drag reduction wheel 45 is provided inside the movable lampshade 4. The drag reduction wheel 45 is arranged in the slide groove 31. Through the design of the drag reduction wheel 45 and the slide groove 31, when relative movement occurs between the movable lampshade 4 and the positioning lampshade 3, the resistance and wear of the movable lampshade 4 and the positioning lampshade 3 are small, thereby improving the stability and service life of the lighting device.

[0063] The light head 21 is movably inserted into the interior of the positioning lampshade 3. The movable lampshade 4 is provided with an expanded lightshade 41. The device limits the lighting range through the expanded lightshade 41 to provide different stage lighting effects.

[0064] The movable lampshade 4 is provided with an axle seat 42 , and the sleeve seat 5 is rotatably connected in the axle seat 42 . The axle seat 42 is provided to provide lateral support for the sleeve seat 5 , thereby ensuring that the sleeve seat 5 is subjected to stable force.

[0065] In summary, the method for controlling the color of stage lighting of the present invention has the following advantages: first, the color control is flexible and changeable. By controlling the far and near motion and deflection motion of the prism 6, as well as the motion speed and the stop position, the color range of the lighting can be precisely controlled to produce a variety of lighting effects, thereby meeting the demand for the diversity of lighting colors in stage performances;

[0066] Second, the lighting device has a compact structure and is easy to install. The lighting device adopts the design of the assembly positioning bracket 1 and the inner bearing frame 11, which has a compact structure and is easy to install and disassemble. At the same time, the installation method of the movable lampshade and the multi-prism is also convenient for replacement and maintenance;

[0067] Third, the lighting device control unit 7 is reasonably designed. Through the combination of the driving motor 751, the worm 752 and the worm wheel 753, the movable lampshade 4 and the prism 6 are precisely controlled. This design not only has high transmission efficiency, but also can achieve smooth rotation and reduce noise and vibration.

[0068] Fourthly, the polygonal prism 6 is easy to install. The sleeve 5 is provided with an embedding groove 51 and a locking assembly 9, which facilitates the installation and fixation of the polygonal prism 6 and ensures the stability of the polygonal prism 6 during the rotation process.

[0069] Fifth, the lighting device is easy to operate and control. The control logic of the entire lighting device is clear. Through the cooperation of the control unit 7 and the deflection unit 8, precise control of the light color change is achieved, and the operation is simple and easy.
