Description

Technical Field

[0001] The utility model relates to the field of street lamps, and more specifically to an anti-fog type LED street lamp for urban lighting. Background Art

[0002] Street lamps are widely used in cities, including urban roads, parks, squares, commercial areas and residential areas. They not only provide lighting for people, but also improve the safety of cities. With the advancement of science and technology, street lamp technology is also constantly innovating and improving. LED street lamps have the advantages of energy saving, high efficiency and long life, and gradually become the mainstream street lamps.

[0003] Traditional street lamps have limited luminous areas and can often only illuminate limited areas, resulting in a limited lighting range. This may cause lighting blind spots in certain areas of roads or public places, affecting the safety of pedestrians and vehicles. Street lamps with insufficient luminous areas may not be able to achieve sufficient brightness, making the environment dim at night or in low light conditions. This will increase the risk of traffic accidents and reduce people's sense of security. In addition, the anti-fog effect is poor. In severe weather conditions such as foggy or rainy days, the light penetration of street lamps may be insufficient. This will cause the light to decay rapidly in the fog and fail to illuminate distant roads or objects, increasing the risk of traffic accidents. Utility Model Content
