A brief history of streetlight development

The history of human development is a history of entrepreneurship that pursues light. The use of fire is an important milestone in the progress of human civilization. The bonfire lit by the ancient ancestors was the earliest light.

In 1843, the first street lamp appeared on the streets of Shanghai, China. Although it was ignited by kerosene, it was more holy than the moonlight in people's minds. The crowds on the banks of the Huangpu River are dedicated to a glimpse. Later, the street lights in the Shanghai concession were changed to gas lights. It was transplanted from London, and the brightness is several times higher than that of the kerosene lamp. In the eyes of pedestrians at night, it is simply the "sun" at night. Until 1879, Shanghai Ponte Dock finally illuminated China's first electric light, equipped with a 10-horsepower internal combustion engine generating unit, equivalent to the power of a walking tractor.

The initial road lights installed a knife switch on each pole, and the workers still need to turn them on and off every day. Three years later, a number of street lights were used in combination with a switch. This type of street light has been used in cities throughout the country until the 1950s.

UK: Humans trying to artificially illuminate on city streets began in the early 15th century. In 1417, in order to brighten the dark nights of London, London Mayor Henry Barton issued an order to hang lighting fixtures outdoors. Later, his initiative was supported by the French. At the beginning of the 16th century, lighting fixtures had to be installed outside the windows of the residential buildings in Paris. At 14 o'clock in Louis, there were many street lights on the streets of Paris. In 1667, Louis XIV, known as the "Sun King", officially promulgated the Urban Road Lighting Act. Legend has it that it was because of the promulgation of this decree that the rule of Louis XIV was called the "Bright Age" in French history.
