[0036] like Figure 1 As shown, the stage lighting control method of the present invention includes a plurality of LED light components 10, a power drive line 20, and an address signal line 30. Each LED light component 10 is connected in parallel on the power drive line 20, and each LED light component 10 is connected in series on the address signal line 30.

[0037] In this stage lighting control method, each LED light assembly 10 is connected in parallel to the power drive line 20, and each LED light assembly 10 is connected in series to the address signal line 30. This can greatly improve the synchronization of the lights when controlling each LED light assembly 10, thereby enabling the stage lights to output a better lighting atmosphere.

[0038] like Figures 2 to 9 As shown, the stage lighting control method also includes several lamp housings 1, each lamp housing 1 having a snap-fit ​​notch 11 at both ends. The lamp housings 1 are arranged side-by-side, with the ends of adjacent lamp housings 1 rotatably snapped together through corresponding snap-fit ​​notches 11. Each LED light assembly 10 is respectively mounted on each lamp housing 1. In this stage lighting control method, snap-fit ​​notches 11 are opened at both ends of the lamp housings 1, and the lamp housings 1 are arranged side-by-side, with adjacent lamp housings 1 rotatably snapped together through corresponding snap-fit ​​notches 11. This makes the connection between adjacent lamp housings 1 more coordinated, avoiding abrupt transitions between them. This results in a stronger sense of unity and coordination in the overall lighting effect of the stage lights, leading to a better overall lighting effect and ultimately creating a better lighting experience.

[0039] like Figures 4 to 9 As shown, the two interlocking notches 11 on the lamp housing 1 are respectively opened on opposite corners of the lamp housing 1. This creates a staggered interlocking structure at both ends of the lamp housing 1, giving the stage lamp with all the lamp housings 1 together better integration, thus facilitating a better lighting effect.

[0040] like Figures 4 to 9As shown, the upper left corner and the lower right corner of the lamp housing 1 are respectively provided with snap-fit ​​notches 11; the bottom surface of the left end of the lamp housing 1 is provided with a mounting groove 12 for mounting the light-emitting component (not shown in the figure), and the top surface of the right end of the lamp housing 1 is provided with a wiring part 13. This not only makes the structure of each lamp housing 1 more coordinated, but also facilitates the formation of good lighting effects and the connection of wires, thereby making the stage lighting control method more reliable and applicable.

[0041] In actual installation and use, the mounting slot 12 can be used to install a cylindrical lamp.

[0042] like Figure 9 As shown, the end face of the lamp housing 1 is an arc surface 101, and the arc surface 101 is arranged around the corresponding rotation center line on the lamp housing 1. This not only gives the lamp housing 1 high coordination, but also better meets the rotation requirements, and ensures that the lamp housing 1 has high stability and reliability, thereby helping to further improve the reliability and applicability of the stage lighting control method.

[0043] like Figures 2 to 9 As shown, the rotating connection between adjacent lamp housings 1 is equipped with a toothed locking mechanism 2 that can lock the rotating connection and unlock by pressing. This mechanism, with its teeth, provides a strong locking effect while meeting folding requirements. This effectively improves the positioning strength of the folding connection, allowing the stage light to remain in a more stable state, thus facilitating a more stable lighting atmosphere. It also allows for the assembly of more lamp housings 1, enabling the acquisition of more lighting states. Furthermore, the toothed locking mechanism 2 can be unlocked by pressing, making the folding and adjustment of the stage light very convenient and effectively improving adjustment efficiency.

[0044] like Figure 6 , Figure 8 , Figure 12 and Figure 13As shown, the toothed locking mechanism 2 includes an arc-shaped rack 21, a toothed locking body 22, at least one return spring 23, and at least one pressing member 24. Between adjacent lamp housings 1, the arc-shaped rack 21 is fixedly mounted on one of the lamp housings 1. The toothed locking body 22 is slidably mounted on the other lamp housing 1, moving away from and closer to the arc-shaped rack 21. The return spring 23 is mounted on the other lamp housing 1, and the toothed locking body 22 engages with the arc-shaped rack 21 through the elastic push of the return spring 23. The pressing member 24 is slidably mounted on the other lamp housing 1, and when the pressing member 24 is pressed, it pushes the toothed locking body 22 away from the arc-shaped rack 21 and compresses the return spring 23. This toothed locking mechanism 2 has a very simple and reliable structure, which not only facilitates manufacturing but also helps to form a very stable and reliable locking effect and ensures very convenient unlocking. This helps to further improve the reliability and applicability of the stage lighting control method.

[0045] like Figure 6 and Figure 8 As shown, a limiting cavity 14 is formed on the lamp housing 1, extending through the arc-shaped rack 21. The toothed locking body 22 is slidably disposed in the limiting cavity 14. The return spring 23 is arranged in the limiting cavity 14, with its two ends elastically pressing against the end face of the toothed locking body 22 away from the arc-shaped rack 21 and the cavity wall of the limiting cavity 14 away from the arc-shaped rack 21, respectively. One end of the pressing member 24 extends from the outside of the lamp housing 1 and is inserted into the limiting cavity 14. This provides a more accurate, stable, and reliable limiting effect on the toothed locking body 22, thereby making the sliding of the toothed locking body 22 more accurate and stable, and thus facilitating a more stable and reliable locking effect.

[0046] like Figure 6 , Figure 8 , Figure 12 and Figure 13 As shown, a guide slope 221 is provided on the side wall of the toothed locking body 22, and an abutting slope 241 with the same inclination direction as the guide slope 221 is provided on the inner end of the pressing member 24. The abutting slope 241 abuts against the guide slope 221. When the pressing member 24 is pressed, the abutting slope 241 can push the guide slope 221 to move away from the arc-shaped rack 21. This allows the pressing member 24 to more stably and accurately push the toothed locking body 22 away from the arc-shaped rack 21 when the pressing member 24 is pressed, thereby achieving the unlocking operation more accurately and stably, and further helping to improve the reliability and applicability of the stage lighting control method.

[0047] like Figure 6 , Figure 8 , Figure 12 and Figure 13 As shown, there are two pressing members 24, which are respectively arranged on both sides of the lamp housing 1, and the two pressing members 24 act on both sides of the toothed locking body 22. In this way, the movement of the toothed locking body 22 is more stable and accurate by pressing the two pressing members 24 at the same time, thereby facilitating a better unlocking effect.

[0048] like Figure 6 , Figure 12 and Figure 13 As shown, the lamp housing 1 is provided with at least one limiting protrusion 15; the toothed locking body 22 has guide holes and slots 222 that are equal in number and correspond one-to-one with the limiting protrusions 15, and the guiding direction of the guide holes and slots 222 is the same as the sliding direction of the toothed locking body 22; the guide holes and slots 222 are slidably fitted onto the limiting protrusions 15. This facilitates a more stable and accurate guiding effect on the toothed locking body 22, thereby helping to further improve the accuracy and stability of the movement of the toothed locking body 22, and further helping to improve the reliability and applicability of the stage light control method.

[0049] like Figure 6 , Figure 12 and Figure 13 As shown, an anti-detachment protrusion 242 is provided on the side wall of the inner end of the pressing member 24, and the anti-detachment protrusion 242 is located in the limiting inner cavity 14. The anti-detachment protrusion 242 can prevent the pressing member 24 from detaching from the lamp housing 1, which can ensure that the installation and positioning of the pressing member 24 is very stable.

[0050] like Figure 6 , Figure 8 and Figure 13 As shown, the lamp housing 1 is provided with a limiting protrusion 102, and the pressing member 24 is provided with a retaining groove 243, which slides and retains on the limiting protrusion 102. This facilitates accurate and stable limiting and guiding of the limiting protrusion 102, thereby enabling the pressing member 24 to move very accurately and stably.

[0051] like Figures 4 to 9 As shown, a lamp tube 3 for mounting the LED lamp assembly 10 is embedded in the lamp housing 1, allowing the lamp tube 3 to rotate relative to the lamp housing 1 and also fixing the lamp tube 3 to another adjacent lamp housing 1. This not only creates a reliable rotating connection between adjacent lamp housings 1, but also provides a stable and reliable mounting position for the light-emitting components through the lamp tube 3, and facilitates the installation of related wires, thereby helping to further improve the reliability and applicability of the stage lighting control method.

[0052] The aforementioned toothed locking mechanism 2 enables the rotating connection to withstand a force of 150 catties, exhibiting extremely high locking strength. It allows for 180-degree folding and various angle configurations. The lamp housing 1 is made of stainless steel, while the lamp tube 3 is made of aluminum alloy. This stage lighting control method offers exceptional reliability and applicability.

[0053] like Figures 4 to 11 As shown, one end of the lamp tube 3 passes through the fastening notch 11 on the lamp housing 1, and the lamp tube 3 is embedded in another lamp housing 1 within the fastening notch 11. The inner cavity of the lamp tube 3 forms a mounting groove 12. A stepped hole 111, which is larger at one end and smaller at the other end, is formed on the surface of the lamp housing 1 opposite to the fastening notch 11. The smaller end of the stepped hole 111 passes through the fastening notch 11, and the larger end of the stepped hole 111 is connected to the limiting inner cavity 14. The lamp tube 3 is a stepped lamp tube with one end larger than the other end. A fitting ring 31 is fitted onto the lamp tube 3. The arc-shaped rack 21 is set on the fitting ring 31. The fitting ring 31 is fitted onto the smaller end of the lamp tube 3, and the lamp tube 3 can rotate relative to it. The lamp housing 3 is embedded in the stepped hole 111, with the large end of the lamp housing 3, the sleeve ring 31, and the arc-shaped rack 21 located in the large hole of the stepped hole 111. The small end of the lamp housing 3 passes through the small hole of the stepped hole 111 and is embedded in the lamp housing 1 in the fastening notch 11. The small end of the lamp housing 3 is fixed to the corresponding lamp housing 1 by at least one screw (not shown in the figure). A cover ring 112 is installed on the opening of the stepped hole 111, and a shielding cover 113 is provided on the side wall of the cover ring 112, which covers the opening of the limiting inner cavity 14. This allows for a convenient and stable reliable rotating connection between adjacent lamp housings 1, making the connection between adjacent lamp housings 1 more convenient, stable, and reliable.

[0054] like Figure 6 and Figure 8 As shown, the wiring portion 13 is embedded in the lamp housing 1, and the inner end of the wiring portion 13 and the small end of the lamp tube 3 are arranged vertically opposite each other in the inner cavity 100 of the lamp housing 1. This not only facilitates processing and assembly, but also makes it easier to arrange wires between the wiring portion 13 and the lamp tube 3, thereby further improving manufacturing convenience.

[0055] like Figure 2 and Figure 3 As shown, the two lamp housings 1 at the beginning and end are respectively provided with snap-fit ​​connectors 4 and plug-in connectors 5 that can be fastened together. This allows for stable assembly into a circular stage light, which in turn helps to improve the reliability and applicability of the stage light control method.

[0056] During actual assembly, the stage light control method can be folded into shapes such as rectangles, squares, and strips, allowing users to adapt it to their specific needs.

[0057] like Figures 14 to 16 As shown, the snap-fit ​​component 4 is fitted with a positioning component 6 that can slide out of the snap-fit ​​point of the snap-fit ​​component 4. The positioning component 6 has a limiting groove 61, and the snap-fit ​​component 4 is provided with a sliding limiting component 7. When the positioning component 6 is fitted into the snap-fit ​​point of the snap-fit ​​component 4, the limiting component 7 is fitted into the limiting groove 61, and the limiting component 7 can also be pressed out of the limiting groove 61. This not only effectively improves the stability and reliability of the assembly of the snap-fit ​​component 4 and the plug-in component 5, but also ensures that disassembly is very convenient.

[0058] like Figures 14 to 19 As shown, the limiting member 7 is a limiting member with one end larger than the other. The small end of the limiting member 7 passes through the positioning member 6, and the large end of the limiting member 7 can be embedded in the limiting groove 61. The snap-fit ​​member 4 is provided with a first spring (not shown in the figure) that acts elastically on the positioning member 6, and the first spring can elastically push the positioning member 6 away from the snap-fit ​​point of the snap-fit ​​member 4; the snap-fit ​​member 4 is provided with a second spring (not shown in the figure) that acts elastically on the limiting member 7, and the second spring can elastically push the limiting member 7 into the limiting groove 61. When assembling the snap-fit ​​member 4 and the plug-in member 5, first insert one end of the plug-in member 5 into the snap-fit ​​point of the snap-fit ​​member 4, then press the positioning member 6 so that one end of the positioning member 6 passes through the snap-fit ​​point of the snap-fit ​​member 4 and is inserted into the plug-in member 5; at this time, the limiting member 7 is embedded in the limiting groove 61 under the elastic action of the second spring. This prevents the positioning piece 6 from disengaging, thus ensuring that the snap-fit ​​piece 4 and the plug-in piece 5 are stably assembled together. When unlocking is required, pressing the limiting piece 7 disengages it from the limiting groove 61. The positioning piece 6 automatically disengages from the plug-in piece 5 under the elastic action of the first spring, thereby achieving automatic unlocking. Then, the plug-in piece 5 can be pulled out, and the snap-fit ​​piece 4 and the plug-in piece 5 can be separated.

[0059] like Figures 14 to 19 As shown, the plug-in end 51 of the plug-in component 5 is provided with at least one positioning hole 52, and the outer end of the snap-fit ​​component 4 is provided with a snap-fit ​​groove 41. The plug-in end 51 is inserted into the snap-fit ​​groove 41. The positioning component 6 is slidably inserted into the snap-fit ​​component 4, and one end of the positioning component 6 can be inserted into the snap-fit ​​groove 41 and the positioning hole 52. The limiting component 7 is slidably inserted into the snap-fit ​​component 4. This not only makes it convenient and stable to assemble the plug-in component 5 and the snap-fit ​​component 4 together, but also makes it convenient to disassemble. This helps to further improve the reliability and adaptability of the stage lighting control method.

[0060] like Figure 2 , Figure 3 , Figure 17 and Figure 18 As shown, the plug-in end 51 is plate-shaped, and the plug-in component 5 is provided with a wiring portion 13. A lamp tube 3 that can rotate relative to the lamp housing 1 is inserted into the end of the lamp housing 1 that is connected to the plug-in component 5, and the lamp tube 3 and the lamp housing 1 are locked together by a toothed locking mechanism 2, which also makes the lamp tube 3 embedded in the plug-in component 5. This not only makes the assembly of the plug-in component 5 and the lamp housing 1 very stable and reliable, but also helps to form a better lighting effect.

[0061] like Figure 2 , Figure 14 and Figure 15 As shown, the snap-fit ​​component 4 is a housing snap-fit ​​component, and a mounting groove 42 is provided on the snap-fit ​​component 4. The toothed locking mechanism 2 is disposed in the mounting groove 42, and an outer cover 43 is installed on the groove opening of the mounting groove 42. This can accurately limit the movement position of the positioning component 6, thereby improving the stability of the overall structure.

[0062] like Figure 2 , Figure 14 and Figure 15 As shown, the snap-fit ​​component 4 has a snap-fit ​​notch 11 at the end away from the snap-fit ​​groove 41. A lamp tube 3 is embedded in the snap-fit ​​component 4, and the lamp tube 3 is embedded in the corresponding lamp housing 1. A cover ring 44 is installed on the port of the lamp tube 3. This not only makes the assembly of the snap-fit ​​component 4 and the lamp housing 1 very stable and reliable, but also helps to form a better lighting effect.

[0063] like Figure 14 As shown, the positioning element 6 is inserted through the mounting slot 41. This makes the positioning element 6 more stable and reliable in limiting the insertion element 5, thereby helping to further improve the stability and reliability of the assembly of the insertion element 5 and the mounting element 4.

[0064] like Figure 4 and Figure 5 As shown, a scale section 103 for marking the rotation angle and a scale indicator section 104 are respectively provided between adjacent lamp housings 1. This makes it easy for users to judge the amount of rotation angle, thereby improving the accuracy of adjustment.

[0065] The above embodiments are preferred embodiments of the present invention. Any structures similar to those of the present invention and any equivalent changes thereof should fall within the protection scope of the present invention.
