200mm led traffic light | The effect of traffic light color on vision
200mm led traffic light | The effect of traffic light color on vision The use of these three colors as traffic signals is related to the structure of human visual function and psychological response. Our retinas contain rod-shaped and three types of cone-shaped photoreceptor cells. Rod cells are particularly sensitive to yellow light, while the three types of cone cells are most sensitive to red, green and blue light, respectively. Because of this visual structure, it is easiest for humans to distinguish red from green. Although yellow and blue are also easy to distinguish, because the eyeball has fewer photoreceptor cells sensitive to blue light, it is better to distinguish between red and green. Therefore, the color of the traffic light is also asked by the university! Color also has the meaning of activity, to express heat or intensity, red is the strongest, followed by yellow. Green has colder and calmer connotations. Therefore, people often use red for danger, yellow for alertness, and green for safety. Moreover, because red light has the strongest penetrating power, light of other colors is easily scattered, and it is not easy to see in foggy days, while red light is the least likely to be scattered, even if the visibility of the air is relatively low, it is easy to be seen. There will be no accidents. So we use red for prohibition.

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.

Ten years of cooperation | Chainzone is committed to writing a new chapter for the longest expressway in Malaysia
As the longest two-way expressway in Malaysia at present, the North-South Expressway in Malaysia runs through the west coast of the Malay Peninsula with a total length of 772 kilometers. The North-South Expressway connects coastal roads and other important domestic roads, and is an important transportation hub in Malaysia. Chainzone, as the designated supplier of high-speed traffic signal products for the North-South Expressway in Malaysia, has a strategic cooperative relationship for more than 10 years. So far, we have successfully provided and replaced more than 70 sets of traffic signal products for them, and provided timely intelligent traffic signal system solutions according to the gradual expansion of the North-South Avenue. Among them, according to the characteristics of Malaysia's north-south highway extending in all directions and the traffic flow is particularly large, Chainzone installed a VMS on the North-South Expressway to effectively guide the driving traffic to travel in an orderly manner. Chainzone’s VMS is widely used in highways, and has won praise from customers for its powerful traffic guidance function. We have adopted a brimless design, and the surface of the screen is smooth, so that no dust or snow accumulates, and it has a certain self-cleaning ability. At the same time, our VMS adopts lens technology, full-color output, more uniform color performance, and more outstanding warning effect. It adopts dust-proof, waterproof and anti-corrosion aluminum cabinet structure, and the protection level is IP65. Even in the humid and hot climate environment in Malaysia, it can ensure normal operation and long service life! As people pay more and more attention to the timeliness of traffic, Chainzone has also cut into the needs of the times in the application of LED intelligent traffic signal products management system to create safe and reliable road signal products.
