[0002] Stage lighting, also known as "stage illumination," or simply "lighting," is a technique used in stage design. Utilizing stage lighting equipment and techniques, it uses light and color variations to depict the environment, create atmosphere, highlight central characters, establish a sense of stage space and time, shape the external image of the performance, and provide necessary lighting effects, all in accordance with the development of the storyline. With the changing times and lifestyles, stage lighting equipment is widely used in dances, concerts, and other events. To enhance the stage presentation, stage lights often require a lifting and lowering function.

[0003] For example, Chinese Utility Model Patent No. CN202323233811.X discloses a waterproof and dustproof stage lighting device, including a stage lighting body, a mounting base, a lifting base, and waterproof and dustproof components. The stage lighting body is rotatably mounted on the mounting base. A circular toothed column is slidably assembled inside the lifting base. The circular toothed column is welded to the bottom of the mounting base. A retraction block is fixedly connected to the bottom of the circular toothed column. A limit block and a limit shaft are fixedly connected to one side of the lifting base. A toggle block is movably sleeved on the outer circumference of the limit shaft. A pressure block is provided inside the limit block. A first rotating shaft and a second rotating shaft are rotatably mounted inside the lifting base. A first gear, a ratchet, and a handle are fixedly sleeved on the outer circumference of the first rotating shaft.

Detailed Implementation

[0026] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0027] like Figure 1-8 As shown, a fast-lifting lighting device includes a lifting assembly 1. One end of the lifting assembly 1 is provided with a base 2, and the other end is provided with a mounting position 4 for installing a lamp 3. A power source 5 is disposed within the base 2, and the output shaft 6 of the power source 5 is connected to the lifting assembly 1 to drive the lifting assembly 1 to achieve lifting action. The lifting assembly 1 includes an outer tube 7, an outer tube 8 movably disposed around the outer periphery of the outer tube 7, an outer tube 9 movably disposed around the outer periphery of the outer tube 8, an inner tube 10 movably disposed around the inner periphery of the outer tube 7, one end of the inner tube 10 being connected to the outer tube 8, and a slider nut 11 installed at the other end of the inner tube 10. An inner tube 12 movably disposed around the inner periphery of the inner tube 10, one end of the inner tube 12 being connected to the outer tube 9. Next, a slider nut 13 is installed at the other end of the inner tube 12. A hollow screw 14 is installed inside the slider nut 13. A rotating bearing 15 is installed between the outer circumference of one end of the hollow screw 14 and the inner tube 12. A rotating bearing 16 is installed between the outer circumference of the other end of the hollow screw 14 and the slider nut 11. A lead screw 17 is installed inside the hollow screw 14. A rotation-limiting sliding element 18 is installed between the outer circumference of one end of the lead screw 17 and the hollow screw 14. The other end of the lead screw 17 passes through the slider nut 11 and is connected to the power source 5. In actual operation, when the power source rotates at high speed, the cooperation of the inner tube, slider nut, screw and bearing ensures that the three outer tubes do not shake or twist during high-speed lifting and lowering, which greatly improves stability.

[0028] The present invention, through the design of the base 2, can fix it on the ground and directly install the lifting lighting device outdoors. Compared with the prior art, there is no need to build an additional canopy, making it convenient to install and use, and applicable to a wide range of scenarios. Through the design of multiple inner and outer tubes, the three outer tubes of different sizes work together to achieve dustproof and waterproof effects, so as to facilitate use in various outdoor spaces and not limited to stage use (hanging is also applicable).

[0029] In actual operation, when the output shaft 6 of the power source 5 drives the lifting assembly, the output shaft 6 first drives the lead screw 17 to rotate, causing the slider nut 11 to move around the outer circumference of the lead screw 17. This, in turn, drives the outer tube 8 to move through the inner tube 10. Simultaneously, the lead screw 17 drives the hollow screw 14 to rotate synchronously through the rotation-limiting sliding member 18, causing the slider nut 13 to move around the outer circumference of the hollow screw 14. This, in turn, drives the outer tube 9 to move through the inner tube 12, and propels the hollow screw 14 to move. The lifting action is achieved through the forward and reverse rotation of the power source 5. The operation is simple, and automated control can be achieved through programming, eliminating the need for manual control.

[0030] The upper end of the outer tube 3 9 is provided with a lamp holder 21, and a lamp 3 is installed on the lamp holder 21. A folding drag chain 22 is connected between the lamp 3 and the power supply group 27. A power cord is installed inside the folding drag chain 22, thereby providing the power required for lighting of the lamp 3 and protecting the internal power cord from unnecessary safety hazards caused by tangling. It has the effect of dustproof, waterproof and windproof, so as to facilitate outdoor use. A plug 36 is provided between the two ends of the outer tube to fill the tolerance gap between the outer tube 1 7, outer tube 2 8 and outer tube 3 9 after assembly, and improve stability.

[0031] A connector 23 is installed on the outer periphery of one end of the inner tube 10. The outer periphery of the connector 23 is connected to the outer tube 8, so that the inner tube 10 can drive the outer tube 8 to move during the movement.

[0032] A connector 24 is installed on the inner circumference of one end of the inner tube 2 12. One end of the connector 24 is connected to the outer tube 3 9, so that the inner tube 2 12 can drive the outer tube 3 9 to move during the movement.

[0033] A coupling 25 is provided between the output shaft 6 and the lead screw 17 to transmit power. A rotating bearing 26 is installed on the outer periphery of the lead screw 17 to improve stability during rotation. A fixing member 33 is installed on the outer periphery of the rotating bearing 26 and is connected to the base 2.

[0034] The power source 5 is a motor with a speed of 1000-3000 rpm, which can achieve rapid lifting and lowering, thereby quickly adjusting the height of the lighting device. The base 2 is also equipped with a power supply group 27, a motor driver 28, a control motherboard 29, and an address code board 30. The power supply group 27 has a DC24V power supply and a DC70V power supply. Through the programming settings of the motor driver 28, the control motherboard 29, and the address code board 30, multiple lifting and lowering lighting devices can be controlled to lift, lower, and light up according to the programming requirements, so as to achieve the lighting effect of the lamps.

[0035] The base 2 is equipped with a one-button control reset switch 31, which can control the lights to reset with one button. The side of the base 2 has a wire hole 32, which is connected to a square tube 35. A power cord is installed inside the square tube, which can be waterproof and dustproof. It can be used in multiple scenarios and can be used to connect several adjacent lighting devices to achieve a matrix lighting effect.

[0036] The outer periphery of the limiting sliding member 18 is formed with a limiting protrusion, and the inner periphery of the hollow screw 14 is formed with a limiting groove, so that when the screw 17 rotates, it can drive the hollow screw 14 to rotate simultaneously through the cooperation of the limiting protrusion and the limiting groove.

[0037] A braking device 37 is provided on the lead screw 17. The braking device 37 includes a torsion spring 38 and a torsion spring base 39. This device is existing technology. When the lead screw rotates forward and rises, the torsion spring is in a forward-opening state. The lead screw rotates, but the torsion spring remains stationary. The nut of the torsion spring base is connected to the lead screw, so no friction is generated, resulting in smooth ascent. Conversely, when the lead screw reverses and descends, the torsion spring and the torsion spring nut base generate surface friction, increasing resistance and effectively controlling the descent speed. This increases the self-locking force and creates a braking effect during descent.

[0038] A matrix device has a number of rapidly rising and falling lighting devices, with adjacent lighting devices connected by square tubes 35 to form a lighting matrix.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
