Description

Technical Field

[0001] This utility model relates to the field of lighting fixtures, and in particular to a portable work lamp. Background Technology

[0002] In industrial production, equipment maintenance, and outdoor operations, portable work lights need to meet the requirements of multi-light source expansion, quick assembly and disassembly, and stable connection. Existing technologies for portable work lights often employ single mechanical fixing mechanisms (such as threaded connections or simple snap-fits), which suffer from cumbersome operation, poor alignment, and insufficient vibration resistance. While some designs incorporate magnetic adsorption to improve connection convenience, relying solely on magnetic force can easily lead to the side light components accidentally detaching under complex working conditions (such as equipment vibration or accidental collisions), affecting operational safety. Furthermore, existing expansion solutions struggle to achieve stable cascading of the main light and multiple side light components. When the number of lighting units increases, insufficient overall structural rigidity can easily cause light source wobbling, reducing lighting stability.

[0003] Based on this, it is necessary to propose a brand-new work light that has high connection reliability and can be quickly connected. At the same time, the work light can also achieve multi-directional lighting, which can meet the lighting needs of different directions and effectively improve the flexibility of product use.
