Description

Technical Field

[0001] The utility model belongs to the technical field of street lamps, and in particular relates to an LED anti-falling street lamp. Background Art

[0002] Street lights refer to lamps that provide lighting for roads. LED street lights refer to street lights made of LED lamps. They have excellent characteristics such as safety, energy saving, and high efficiency. They provide good lighting conditions for people's travel and car driving to ensure the safety of driving. They are an important part of urban road lighting.

[0003] When the existing street lamps are in use, they are mainly fixedly connected to the lamp poles by bolts. After long-term use, the bolts absorb moisture in the air and rust, so the bolts are easy to fall off, causing the street lamps to fall, which poses certain safety hazards. In addition, the street lamps are easily broken and cannot be used. The lamp head and the lamp pole of the street lamp are supported by only a connecting rod. In the event of typhoons, earthquakes and other weather, the lamp head is easily scraped off, thereby separating the lamp head from the lamp pole. After the lamp head falls, it may cause secondary damage to the road surface or pedestrians, which invisibly increases the safety hazards. Therefore, it is necessary to strengthen the anti-falling measures for the lamp head. Utility Model Content
