200mm led traffic light | The emergence of red, yellow and green traffic lights
200mm led traffic light | The emergence of red, yellow and green traffic lights With the development of various means of transportation and the needs of traffic command, the first veritable three-color light (red, yellow and green three signs) was born in 1918. It is a three-color circular four-sided projector that was installed on a tower on Fifth Street in New York City, and thanks to its birth, urban traffic has been greatly improved. The inventor of the yellow signal light is my country's Hu Ruding. With the ambition of "saving the country through science", he went to the United States to further his studies and worked in General Electric Company, where the great inventor Edison was the chairman. One day, he was standing at the bustling intersection waiting for the green light signal. When he saw the red light and was about to pass, a turning car whirring past him, scaring him into a cold sweat. Back in the dormitory, he pondered over and over again, and finally thought of adding a yellow signal light between the red and green lights to remind people to pay attention to the danger. His suggestion was immediately affirmed by the relevant parties. Therefore, the red, yellow and green signal lights are a complete command signal family, all over the world's land, sea and air traffic fields.

200mm led traffic light | LED traffic light development
200mm led traffic light | LED traffic light development In the early 19th century, in York City in central England, red and green clothes represented different identities of women. Among them, the woman in red means that I am married, while the woman in green is unmarried. Later, horse-drawn carriages often ran over people in front of the House of Parliament in London, so people were inspired by red and green clothes. On December 10, 1868, the first member of the signal family was born on the square of the House of Parliament in London. The lamp post, designed and manufactured by British mechanic DeHart at that time, was 7 meters high, and hung a red and green lantern - gas traffic signal, which was the first signal lamp on the city street. At the foot of the lamp, a policeman with a long pole pulled the belt to change the color of the lantern at will. Later, a gas lampshade was installed in the center of the signal light, and two pieces of red and green glass were alternately shaded in front of it. Unfortunately, the gas lamp, which has only been available for 23 days, suddenly exploded and extinguished itself, killing a policeman who was on duty. Since then, the city's traffic lights have been banned. It was not until 1914 that the city of Cleveland in the United States took the lead in restoring traffic lights, but at this time it was already an "electrical signal light". Later, in cities such as New York and Chicago, traffic lights reappeared one after another.
