Do you know what traffic lights are?
Traffic lights are signal lights that direct traffic operations, generally consisting of red lights, green lights, and yellow lights. A red light means no passage, a green light means passage is permitted, and a yellow light means a warning. Traffic lights are divided into: motor vehicle signal light, non-motor vehicle signal light, pedestrian crossing signal light, direction indicator light (arrow signal light), lane signal light, flashing warning signal light, road and railway level crossing signal light. At the intersection, there are red, yellow, green and three-color traffic lights hanging on all sides. It is a silent "traffic police". Traffic lights are internationally unified traffic lights. A red light is a stop signal and a green light is a go signal. At the intersection, cars from several directions gather here, some have to go straight, some have to turn, and whoever goes first is to obey the traffic lights. When the red light is on, it is forbidden to go straight or turn left, and the vehicle is allowed to turn right without obstructing pedestrians and vehicles; when the green light is on, the vehicle is allowed to go straight or turn; when the yellow light is on, it stops within the stop line at the intersection or the pedestrian crossing line and has continued to pass; When the yellow light is flashing, warn the vehicle to pay attention to safety.

No fear to challenge! Chainzone assists the world's longest undersea road tunnel
Norway has a complex terrain but has built the longest undersea road tunnel in the world, the Norwegian Ryfast Highway, which solves many problems such as local travel difficulties and promotes the development of local tourism.Chainzone is the only traffic guidance system solution provider for Ryfast Highway in Norway. We have successfully installed more than 2,000 sets of LED traffic signal products conforming to the European standard EN12966 on Ryfast Highway, contributing to this huge project.After we have a deep understanding of the humid and cold weather in Norway, we know that the hardware configuration is very important for the product to be used normally in a long-term humid and cold climate with heavy salt spray near the sea, so we use moisture-proof and anti-corrosion aluminum-stainless steel as the outer frame material, the operating temperature range is as low as -30°C, which can ensure normal operation even in long-term extremely cold and humid weather or heavy salt spray at the seaside.In addition, in order to deal with hidden safety problems such as dark tunnels and complex and changeable road conditions, we make professional judgments on specific situations in product design, especially optical performance, and use patented lens technology to gather light in dim environments, the maximum brightness can reach 8000nits, so that the driver can clearly see the content of the guidance instructions within the visual range, without glare or halo.As the longest undersea road tunnel in the world, its deepest point is 290m below sea level, which is particularly laborious in terms of human and material resources. In the installation and maintenance of the product, we actively cooperate and communicate with the local construction personnel, in order to achieve perfection in the installation and future maintenance, and have also been unanimously affirmed and praised by the Norwegian engineering team.

LED road signage | LED zebra crossing emerges for smart transportation construction
LED road signage In recent years, thanks to the continuous progress of LED technology and the vigorous promotion of smart transportation construction, LED zebra crossings that "can speak and glow" have covered many cities, adding assistance to urban appearance and civilization construction, and lighting up traffic intersections. The "Life Protection Line" has formed a beautiful landscape. LED zebra crossing, also known as smart zebra crossing, is a new type of transportation facility that has appeared in recent years. . Lighting: According to the change of the color of the LED indicator, passing vehicles and pedestrians can get warnings from it, reminding people to pay attention to courteous passage. When pedestrians walk on the zebra crossing, the LED light will emit green light; when the traffic light is red, it will emit red light to remind pedestrians not to pass; when the red light and green light are about to change, the ground light will emit yellow light. Can "speak": When pedestrians stand on the zebra crossing, different voice prompts will be issued as the color of the traffic lights changes, such as "red lights are prohibited", "please observe traffic safety" and so on. When there is a violation of traffic rules such as running a red light, a voice broadcast will be quickly issued to warn, and it will also be exposed on the LED display synchronously.

Seoul installs ground traffic lights for bowheads
Traffic lights In order to prevent the traffic accidents of the "bow-headed people", various districts in Seoul, South Korea set off an upsurge of installing "ground signal lights". According to a report by Yonhap News Agency on the 11th, the ground signal lights are installed on the waiting line of the pedestrian crossing and are LED signal light auxiliary devices used to inform pedestrians of the change of the signal lights. Since the ground signal lights and the frame signal lights are linked, they will operate 24 hours a day. Currently, nearly 1,200 ground signal lights are installed in 25 districts in Seoul, of which Gangnam has the most (138). Relevant sources said that the ground signal lights were originally used to prevent traffic accidents for the bow-headed people. Later, they found that they could remind children who are close to the lane to back off. Therefore, many parents and schools of students asked for more ground signal lights. Although the ground signal lights also attracted some complaints, such as being too dazzling at night, the general public responded well, and the parents of the students were even more welcome. According to the Seoul Metropolitan Government, the installation cost of each ground signal light is about 25 million to 30 million won.
