Description

Technical Field

[0001] This utility model relates to a lighting fixture structure, and in particular to a stadium light that is easy to assemble and disassemble. Background Technology

[0002] Stadium lights are lighting devices specifically designed for ball sports fields. They have advantages such as energy saving and environmental protection, good light quality, anti-glare, high illuminance and uniformity. They are mainly used to provide sufficient lighting at night or in environments with insufficient light, ensuring that athletes and spectators can clearly see the game.

[0003] As shown in patent CN202411077212.X, currently, the lens fixing method for stadium lights mainly consists of multiple screws on the inner ring and multiple screws on the outer ring. This has the following drawbacks for both the production end and the customer end:

[0004] 1. During the production process, when employees spend a long time screwing in screws, there is a risk that screws may be missed or not tightened properly, which may lead to the failure of the LED light board's waterproofing. In addition, due to various reasons during production, defects such as stripped internal threads of screws may occur, rendering the entire heat sink unusable. This results in a waste of assembly time and raw materials, which in turn increases the defect rate of assembled products, consumes the physical strength of employees, and affects work efficiency.

[0005] 2. Due to site requirements, the client may need to replace the lens with a lens that has a larger or smaller angle. When replacing the lens, the large number of fixing screws will result in low efficiency, increased installation costs, and impact on the installation schedule. Utility Model Content
