Description

Technical Field

[0001] This utility model belongs to the field of stage lighting technology, specifically relating to a split-type connection mechanism for a waterproof stage light head shell and a stage light. Background Technology

[0002] With the rapid development of the cultural and entertainment industry, outdoor performances are increasing, such as music festivals and outdoor film festivals. These events place higher demands on the waterproof performance of stage lights to prevent equipment damage or reduced lighting effects caused by rain and other environmental factors. Stage performances also require increasingly higher standards for the color, brightness, and angle of the lights, necessitating stage lights with more functions and adjustability. A modular connection mechanism allows for easier replacement and upgrading of the lamp head housing to meet diverse lighting needs.

[0003] Traditional stage light head housing connection methods may present difficulties in installation and disassembly, leading to increased maintenance costs and reduced efficiency. While some stage light head housings have solved the problem of complex installation and disassembly, they may be insufficient in terms of waterproof performance, especially in outdoor performance environments where they are easily affected by environmental factors such as rain.

[0004] Currently, most waterproof stage lighting fixtures require complete sealing and waterproofing, with the lamp head housing module and lamp head shaft assembled as a single unit. These modules cannot be easily and independently disassembled. Internal functional modules must be inserted into the housing for installation. During overall lamp body debugging, individual functional modules cannot be adjusted due to the housing enclosure. Auxiliary adjustment devices or fixtures must be used externally to adjust each function, including light path correction, to optimal levels before the lamp body modules are inserted into the housing. While these waterproof lighting fixtures can be quickly debugged and installed using auxiliary adjustment devices or fixtures during mass production (see CN216491394U for a stage lighting debugging device), the lack of such fixtures causes significant problems for customers during use, maintenance, and debugging.
