[0022] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] Stage lighting is an important part of the performance space. It is an artistic creation that designs the lighting environment of the characters and the specific scenes required according to the development of the plot, and purposefully reproduces the design intention to the audience in the form of visual images. In order to achieve this performance effect, in modern stage design, it is often necessary to install a large number of stage lights, which are installed above the stage to play the role of lighting and color light effects. However, the general stage effect is relatively complex, and the illumination height varies. There are even stepped stage panels or multi-step stage tops that need to be installed with stage lights as a whole. Due to the high requirements for the integrity of stage lighting and the differences in the installation height of stage lights, such multi-step stage lights are very difficult to install, difficult to control, poor stage effects, and inconvenient to maintain.

[0024] Embodiment 1: Figure 1 , 2 The figure is only one of the embodiments of the present invention, an adjustable multi-height rotating stage light, comprising a lamp tube 1, a connecting rod 2 connected to the lamp tube 1 and a mounting base 3 connected to the connecting rod 2, the connecting rod 2 comprising an electric cylinder 21 connected to the mounting base 3 and an axle 22 coaxially connected to the lamp tube 1, the lamp tube 1 rotates around the axle 22, the outer shell of the lamp tube 1 is provided with a rotating ring 11 and a first slide groove 12 for facilitating the sliding of the rotating ring 11, the rotating ring 11 is provided with meshing teeth 111, and the mounting base 3 is provided with a second slide groove 31 for facilitating the sliding of the electric cylinder 21.

[0025] In the present invention, the lamp tube 1 is connected to the mounting base 3 through a connecting rod 2. The mounting base 3 is generally a stage floor or a stage top surface. The connecting rod 2 includes an electric cylinder 21 connected to the mounting base 3 and a shaft rod 22 coaxially connected to the lamp tube 1. The electric cylinder 21 can drive the shaft rod 22 to extend and retract to control the distance between the lamp tube 1 and the mounting base 3, that is, to control the height of the lamp tube 1. The lamp tube 1 rotates around the shaft rod 22, that is, the lamp tube 1 can rotate to form a rotating stage lighting effect. A rotating ring 11 and a first slide groove 12 for facilitating the sliding of the rotating ring 11 are provided on the outer cover of the lamp tube 1. The rotating ring 11 can slide on the first slide groove 12 along the extension direction of the lamp tube 1. However, when the rotating ring 11 rotates, the lamp tube 1 will also rotate synchronously. When multiple lamp tubes 1 are installed on the mounting base 3 at the same time, the rotating rings 11 of the lamp tubes 1 are meshed with each other through the meshing teeth 111. Only one lamp tube 1 needs to be driven to rotate to drive more lamp tubes 1 to rotate.

[0026] In addition, the number of the lamp tube 1 and the connecting rod 2 is at least one. All the lamp tubes 1 can even be meshed and connected in sequence through the rotating ring 11, and when one lamp tube 1 is driven to rotate, all the lamp tubes 1 can rotate synchronously, with high integrity.

[0027] It should be noted that the mounting base 3 is provided with a second slide groove 31 for facilitating the sliding of the electric cylinder 21. After the first lamp tube 1 is installed, the second lamp tube 1 is displaced along the second slide groove 31 toward the first lamp tube 1 until the rotating ring 11 of the second lamp tube 1 is tightly attached to the rotating ring 11 of the first lamp tube 1. Under tight pressure, the rotating rings 11 of the two are engaged and generate greater friction with each other, ensuring that the rotating rings 11 will not slip away when the two lamp tubes 1 rotate. Then, the third and fourth lamp tubes 1 are installed in turn, and so on. All the lamp tubes 1 are installed.

[0028] In this way, it can be ensured that all the lamp tubes 1 are extended and retracted by the electric cylinder 21 during rotation, and the height is raised and lowered while rotating, with high integrity and good control effect.

[0029] The adjustable multi-height rotating stage lamp of the present invention has a simple structure and good overall effect, can be installed at multiple steps and multiple heights, is easy to control, has high adjustability, and is suitable for use in various situations.

[0030] Embodiment 2, still as Figure 1 , 2 The figure is only one embodiment of the present invention. In order to make the adjustable multi-height rotating stage light of the present invention have better adjustment effect and higher stability, the present invention also has the following designs:

[0031] Firstly, the number of the rotating ring 11 is at least one. When the other lamp tubes 1 on both sides of a lamp tube 1 require different rotation speeds, two rotating rings 11 of different sizes can be set on the lamp tube 1. Even if the lamp tubes 1 on both sides of the lamp tube 1 are of the same size and the rotating rings 11 are of the same size, their rotation speeds are different. According to this principle, at least one rotating ring 11 of different sizes can be set on each lamp tube 1 to achieve the simultaneous rotation of all the lamp tubes 1 but at different rotation speeds. The above rotation speeds all refer to the angular velocity of rotation of the lamp tube 1.

[0032] It should also be noted that since the size of the rotating ring 11 on each lamp tube 1 can be changed according to the design, the distance between two adjacent lamp tubes 1 will change accordingly. Therefore, it is even more necessary for the lamp tube 1 to slide on the second slide groove 31 of the mounting seat 3 under the drive of the connecting rod 1, so that the distance between any two adjacent lamp tubes 1 can be adjusted.

[0033] Then, a limiting groove 311 is provided in the second slide groove 31, and a limiting block 211 located in the limiting groove 311 is provided at the end of the electric cylinder 21, and the width of the limiting block 211 is not less than the slot width of the second slide groove 31, that is, the second slide groove 31 is wide inside and narrow outside, and the limiting block 211 at the end of the electric cylinder 21 can just be inserted into the spacious limiting groove 311 inside the second slide groove 31, but cannot slide out from the narrow slot outside the second slide groove 31, so that the limiting block 211 can only be embedded in the limiting groove 311 from the end of the second slide groove 31, and connected to the electric cylinder 21 passing through the slot of the second slide groove 31, thereby preventing the electric cylinder 21 from falling off and ensuring the connection stability of the lamp tube 1.

[0034] Moreover, the limit block 211 is arranged perpendicular to the electric cylinder 21 , which not only ensures the stability of the lamp tube 1 , but also limits the extension direction of the electric cylinder 21 , the shaft 22 and the lamp tube 1 to always remain perpendicular to the mounting base 3 .

[0035] Of course, the limiting block 211 is a square block, so that the limiting block 211 will not rotate in the second sliding groove 31, ensuring that the connecting rod 2 will not rotate, and only the lamp tube 1 will rotate relative to each other.

[0036] In addition, at least a part of the rotating ring 11 is located in the first slide groove 12, ensuring that the rotating ring 11 can slide freely along the first slide groove 12 in the axial direction, but the rotating ring 11 keeps synchronization with the lamp tube 1 in the radial direction under the limitation of the first slide groove 12, ensuring that when the lamp tube 1 rotates, the rotating ring 11 will rotate along with it under the drive of the first slide groove 12, that is, the rotating ring 11 and the lamp tube 1 rotate synchronously.

[0037] In addition, the number of the first sliding groove 12 is at least one, so as to ensure that the limiting effect of the rotating ring 11 is better and the stability is higher.

[0038] Furthermore, a light lens 111 is disposed on the lamp tube 11. Of course, the number of the light lens 111 is at least one, so as to create a rotating light and shadow effect.

[0039] Finally, the mounting seat 3 is provided with a PLC controller electrically connected to the electric cylinder 21, and the PLC controller controls the extension and retraction of the electric cylinder 21. At the same time, a position sensor is provided on the lamp tube 1, and the position sensor is electrically connected to the PLC controller. The position sensor on the lamp tube 1 obtains the position of the lamp tube 1 and feeds it back to the PLC controller to form a closed-loop control to prevent position deviation caused by long-term operation.

[0040] The adjustable multi-height rotating stage lamp of the present invention has a simple structure and good overall effect, can be installed at multiple steps and multiple heights, is easy to control, has high adjustability, and is suitable for use in various situations.

[0041] The present invention is not limited to the above specific implementations, and the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made to the above implementations based on the technical essence of the present invention shall be included in the protection scope of the present invention.
