Description

Technical Field

[0001] This utility model relates to the field of moving head light technology, specifically to a moving head stage light with horizontal and vertical rotation structure and a stage light. Background Technology

[0002] Modern stage lights are widely used in indoor and outdoor performances. In addition, they are also used in outdoor live performances, large stadiums, theme parks, urban lighting projects, landscape lighting, and outdoor cultural event venues. These outdoor scenarios place higher demands on the performance and protection capabilities of stage lights.

[0003] Existing stage lights generally consist of three parts: a base, a support arm, and a lamp tube. The base houses the power supply, control board, and other electronic components. The support arm supports the lamp tube and allows it to rotate horizontally, vertically, or in a tilting motion to meet the requirements of flexible lighting angle changes during performances or set design. A high-power laser light source inside the lamp tube is used for illumination and various lighting effects. Because the lamp needs to oscillate according to the music and lighting direction during performances and set design, and because outdoor use is subject to rain and fog, the accuracy of the oscillation and the reliability of the joints must be ensured. Current main protective measures are limited to using waterproof motors and waterproof cables for the power and signal lines at the connection points between the support arm and the base. After a period of indoor and outdoor use, the motor heat causes temperature changes in the drive pulley, leading to oxidation. Furthermore, water ingress and slippage of the drive belt after prolonged use can cause belt breakage, affecting the lifespan and accuracy of the stage light's operation. In addition, existing lighting fixtures do not make good use of internal space. The transmission structure and drive motor occupy a large amount of internal space. Placing the transmission mechanism inside the support arm increases the size of the outer casing, making it difficult to install and project light. Utility Model Content

[0004] One of the purposes of this utility model is to provide a horizontal and vertical rotation structure for a moving head stage light. By utilizing the unused space of the base housing and the lamp head, the horizontal rotation and transmission structure are respectively set inside the base housing, while the vertical rotation drive motor and transmission structure are set inside the lamp head. This reduces the thickness of the lamp arm while satisfying the projection orientation change of the lamp head module, thus solving the problem of large lamp volume.

[0005] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:

[0006] A moving head stage light with horizontal and vertical rotation structure includes a lamp tube, a rocker arm, and a base. The lamp tube is rotatably connected to the rocker arm, and the rocker arm is rotatably connected to the base. The lamp tube includes a cylindrical shell and a first rotating device. The first rotating device is disposed inside the cylindrical shell and includes a first driver, a first bracket, a first central shaft, and a first synchronous wheel. A portion of the first central shaft is disposed on the rocker arm, and another portion is rotatably connected to the lamp tube. The first bracket is disposed on the inner wall of the cylindrical shell, and the first driver is disposed on the first bracket. The first synchronous wheel is rotatably connected to the first central shaft and is connected to the cylindrical shell. The first driver drives the first synchronous wheel to rotate. The first central shaft acts as a joint connection, improving the load-bearing capacity, and the first rotating device is built into the cylindrical shell for protection.

[0007] Furthermore, the first rotating device also includes a first encoding sensor and a first positioning sensor. The first encoding sensor is disposed on the first driver, and the first positioning sensor is disposed on the inner wall of the cylinder shell and opposite to the first synchronous wheel. The first positioning sensor realizes position feedback by detecting the magnetic mark on the first synchronous wheel. The first driver drives the first synchronous wheel to rotate by a synchronous belt for feedback adjustment.

[0008] Furthermore, the first bracket is provided with a first elastic element, one end of which is connected to the first bracket and the other end is connected to the cylinder shell, absorbing vibrations during rotation and improving the accuracy of rotation.

[0009] Furthermore, the first rotating device also includes a first bearing, a first oil seal, and a locking plate. The first bearing is sleeved on the outer wall of the first central shaft, the first oil seal is disposed on the first bearing, and the first locking plate is disposed on one end face of the first bearing to lock the position of the lamp tube and improve the sealing at the joint.

[0010] Furthermore, the first rotating device also includes a slot, which is disposed on the inner wall of the cylindrical shell and located outside the first synchronous wheel, for zero-point positioning and insertion of a lighting effect device.

[0011] Furthermore, the rocker arm includes a bracket, a second rocking device, and a power device. The second rocking device is mounted on the bracket, and the power device is mounted inside the base. The power device drives the second rocking device to rotate, thereby causing the rocker arm to rotate.

[0012] Furthermore, the second rotating device includes a second central shaft, a second bearing, a shaft platform, and a second synchronous wheel. The shaft platform is mounted on the bracket, the second central shaft is rotatably connected to the shaft platform by the second bearing, and the second synchronous wheel is connected to the shaft platform for vertically rotating the lamp tube.

[0013] Furthermore, the power unit includes a second driver, a second bracket, an adjusting plate, a second elastic element, a second positioning sensor, and a second encoding sensor. The second bracket is mounted on the base, the second driver is mounted on the second bracket and drives the second synchronous wheel to rotate, the second encoding sensor is mounted on the second driver, the adjusting plate is mounted on the second bracket, one end of the second elastic element is connected to the second bracket, and the other end is connected to the adjusting plate, and the second positioning sensor is mounted on the second bracket and is opposite to the second synchronous wheel for accurately controlling the rotation direction.

[0014] Furthermore, both the first and second central shafts are hollow shafts, and the bracket is provided with a cable channel. The cable channel connects the lamp tube and the base through the first and second central shafts, thereby protecting the cable.

[0015] The second objective of this utility model is to provide a stage light that solves the problem of insufficient adaptability of existing stage lights to complex environments.

[0016] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:

[0017] A stage light includes a horizontal and vertical rotating structure for the moving head stage light, enabling stable lighting control.

[0018] The beneficial effects of this utility model are as follows:

[0019] (1) The first rocking device on the horizontal and vertical rotation structure of the moving stage light is built into the cylindrical shell and adopts a rigid transmission structure of the first synchronous wheel and the central shaft. Part of the central shaft is inside the cylindrical shell and part is on the rocker arm, which improves the strength of the joint. The driver is installed on the bracket, which makes it convenient to adjust the tightness of the drive synchronous wheel and improves the stability of the transmission. The motion structure during pitch adjustment is set inside the cylindrical shell, which can reduce the space occupied when projecting the light and make the overall thickness thinner.

[0020] (2) The first rocking device of the horizontal and vertical rotation structure of the moving stage light is equipped with an elastic element and the first bracket. The cooperation of the elastic element and the first bracket can offset the interference of motor vibration and housing deformation on transmission accuracy in real time. Compared with the existing rigid fixed structure, it improves the stability of output power. In conjunction with the first encoding sensor and the positioning sensor, by detecting the position of the synchronous wheel and the shaft end mark, it solves the problem of cumulative error caused by signal drift when relying on a single encoder in the existing technology, and improves the positioning accuracy of the rocking.

[0021] (3) The horizontal and vertical rotation structure of the moving head stage light is also equipped with a sealing structure of the first bearing and oil seal, and a cable channel of hollow shaft. It can achieve dust and water protection while ensuring rotation. Compared with the existing structure that only uses waterproof cable and exposed bearing, it improves the dust and water protection performance and ensures use in harsh outdoor environments. The rocker arm and the lamp tube adopt the first or second rocking device with independent drive. Through the distributed control of the power unit, the transmission structure is simplified, the control is more accurate and sensitive, and the response speed of complex lighting scenes is met, which meets the dynamic needs of complex lighting scenes.
