When did street lamps begin to appear in China?

The origin of Chinese street lamps can be traced back to ancient times. In ancient times, street lamps in China were mainly composed of burning torches or oil lamps. However, with the passage of time, the form and function of street lamps have also changed.

According to historical records, the earliest street lamps in China appeared in the Eastern Han Dynasty (AD 25 -220). At that time, street lamps were mainly composed of burning torches, which were used to illuminate the road and facilitate the passage of pedestrians and vehicles. These torches are usually made of wood, which are lit and placed on supports by the roadside. Although the lighting effect of these street lamps is limited, they provide some convenience for night traffic.

With the progress of science and technology, the street lamps in China have gradually changed from torches to oil lamps. According to records, during the Tang Dynasty (6 18 -907), oil lamps were used for street lamps in China. These oil lamps are usually made of ceramics or copper, with oil and wick inside. After the oil lamp is lit, it can be continuously illuminated for a period of time to provide illumination for pedestrians at night.

In the Song Dynasty (960-1279), the street lamps in China were further improved. Street lamps in Song Dynasty adopted more advanced design and materials, such as iron brackets and glass lampshades. These street lamps not only have better lighting effect, but also have longer service life.

With the development of modern science and technology, street lamps in China have gradually changed from traditional torches and oil lamps to electric lamps. According to records, the earliest electric street lamp in China appeared in Shanghai at the end of 19. At that time, the Bund area in Shanghai began to use electric lamps as street lamps, replacing traditional torches and oil lamps. These electric street lamps use electric energy as energy to provide brighter and more lasting lighting effects.

At the beginning of the 20th century, street lamps in China gradually spread to other cities. With the process of urbanization, more and more cities begin to install street lamps to provide better night lighting and traffic safety. By the middle of the 20th century, street lamps have become an important part of urban infrastructure in China.

Generally speaking, street lamps in China originated from ancient torches and oil lamps, and gradually evolved into modern electric lamps after a long development process. The appearance of street lamps not only provides lighting at night, but also improves the city's traffic and the quality of life of residents.
