[0002] A light bracket is a device used to fix and support light equipment. It is usually made of metal or other solid materials, with different structures and designs to meet the installation needs of various types of lights. The main function of a light bracket is to ensure that the light can be stably fixed in a specific position, maintaining a suitable angle and height to achieve the best lighting effect. At the same time, it can also protect the light equipment from damage and impact.

[0003] The mobile lighting bracket for radio and television is a movable lighting support equipment specially designed for the radio and television industry. It has mobility, stability, adjustability and adaptability. The mobility is convenient for flexible arrangement in different scenes and locations, the stability is the ability to keep the light stable during use to avoid shaking, and the adaptability is to match the commonly used lighting equipment in the radio and television industry to ensure good compatibility.

[0004] Most of the existing mobile lighting brackets for broadcasting and television are still plugged in for use, which means that there will be certain connecting wires near the bracket at the shooting site. When moving, the connecting wires need to be put away and then moved. In addition, the bracket is positioned solely by universal wheels, which will also cause the lighting bracket to shake, thereby reducing the stability of the bracket. Summary of the invention

[0005] Based on this, the purpose of the present invention is to provide a mobile lighting bracket for broadcasting and television to solve the technical problems mentioned in the above background technology.

Multiple battery packs can be used to power the lamp head within a certain range, thereby improving the flexibility of the bracket.

[0014] Furthermore, there are four sets of universal wheels, and the multiple sets of universal wheels are located on the same horizontal plane.

[0015] By adopting the above technical solution, multiple sets of universal wheels are provided, and the universal wheel is installed at one end of the suction cup to facilitate improving the stability of the bracket during movement.

[0016] Furthermore, the two groups of universal wheels are located at one end of the suction cup, and the two groups of universal wheels are arranged opposite to each other.

[0017] By adopting the above technical solution, two sets of universal wheels are located at one end of the suction cup, and the two sets of universal wheels are arranged opposite to each other. The arrangement of the positions of the universal wheels effectively improves the stability of the bracket.

[0018] Furthermore, a circular hole is provided at the bottom of the base plate, and a first spring is installed in the circular hole, one end of the first spring is connected to the inner wall of the base plate, and the other end of the first spring is connected to the universal wheel.

[0019] By adopting the above technical solution, the setting of the circular hole reserves space for the first spring and also reserves movement space for the universal wheel.

[0020] Furthermore, a fence is installed on the top of the base plate, and the fence is located on the outer wall of the battery pack.

[0021] By adopting the above technical solution, the setting of the fence effectively protects the bottom plate and the battery pack, improves the safety of the bracket, reduces damage to the battery pack, and thus increases the service life of the battery pack.
