Description

technical field

[0001] The invention relates to the technical field of lighting, in particular to an LED lamp used for nighttime construction lighting. Background technique

[0002] In the actual construction of the construction site, due to the tight schedule or construction needs, construction needs to be carried out at night, so the lighting on the construction site has become an indispensable tool in the construction process. However, due to the long power supply connection required in the construction lighting process , making it extremely difficult to take in and out the wires, increasing the workload and reducing work efficiency. At the same time, when not in use, the power supply wires are exposed to the outside world for a long time and are vulnerable to various accidental damages, such as people trampled on, hard objects scratches, etc., resulting in power supply failures. The insulation skin on the outside of the line is damaged, resulting in a decrease in the ser...
