Description

Technical Field

[0001] This utility model relates to the field of moving head beam lights, specifically a moving head beam light for stage lighting. Background Technology

[0002] Moving head lights are high-tech products that integrate electronics, mechanics, and optics, creating patterns and movable beams through programmed arrangement. They are typically used on stages or in entertainment venues. A moving head light usually consists of a spotlight head, a lamp holder, and a base. The lamp holder can rotate at a certain angle relative to the base, while the light head can rotate accordingly relative to the lamp holder. Simultaneously, the light source, driven by a prism, changes the angle or rotation of the beam. When powered on, the spotlight head rotates while illuminating the stage and backdrop, creating a rotating and changing lighting effect on the stage.

[0003] When installing moving head lights, they are usually suspended on the suspension using an arc plate, and the bolts are rotated with a handle to make one end abut against the suspension, thus achieving a fixed installation of the moving head beam light. However, during the use of the moving head beam light, it is necessary to make horizontal and vertical angle adjustments through a motor. After being fixed by a single point, the stability is poor and there are certain safety hazards. Utility Model Content

Moreover, the first clamping plate 3 and the second clamping plate 4 adopt a split structure, so that different sizes of suspensions can be accommodated when the beam light 25 is installed.
