People's development history is an entrepreneurial history pursuing bright, and the use of fire is an important milestone in people's civilization and progress. The bonfires lit by ancient ancestors are the earliest lights.
In 1843, the first street lamp appeared on the streets of Shanghai, China. Although it was lit by kerosene, it is more holy than moonlight in people's minds. The crowds on the bank of the Huangpu River went to see the demeanor. Later, the street lights in the Shanghai Concession were changed to gas lights. Transplanted from London, the brightness is several times higher than that of kerosene lamps. In the eyes of pedestrians at night, it is simply the "sun" at night. It was not until 1879 that China’s first electric light was finally lit at the Shanghai Pudong 16 Pier, equipped with a 10-horsepower internal combustion engine generating unit, equivalent to the power of a walking tractor.
At the beginning, the street lights were equipped with a knife switch on each electric pole, and workers still needed to turn it on and off every day. Three years later, a switch was used for several street lights. This new type of street light was used in various cities in China until the 1950s.
United Kingdom: Attempts to artificially illuminate city streets began in the early 15th century. In 1417, in order to brighten the dark night of London in winter, the Mayor of London Henry Barton issued an order requiring lamps and lanterns to be hung outside. Later, his initiative received the support of the French. At the beginning of the 16th century, lighting fixtures had to be installed outside the windows of Parisian houses facing the street. At Louis XIV, many street lights appeared on the streets of Paris. In 1667, Louis XIV, known as the "Sun King", also officially promulgated the city road lighting decree. Legend has it that it was precisely because of the promulgation of this decree that the reign of Louis XIV was called the "Era of Light" in French history.
