Do all citys use led traffic lights now?

1. [Zunyi City, Guizhou Province] Traffic lights are shipped! ! !
 I am very grateful to the support of Mr. Wang of Zunyi City, Guizhou. Well, after ordering every year from the previous years, this

year we have set up traffic lights at our three intersections. This time is different from the past. In the past, it was a crossroad. This

year is two. Traffic lights need to be installed at intersections and a T-junction.
2. What are the styles of traffic lights in Zunyi City, Guizhou Province?
Our traffic lights in Zunyi, Guizhou, are still the same as before. Each big light pole has a left turn traffic light on it, a left turn red,

yellow and green traffic light, and a set of straight red, yellow and green traffic lights.
This is also in line with national standards, because the recent national standards are two sets of traffic lights, the left turn signal is

the arrow display, specifically for the left turn traffic intersection of vehicles, there is a group, is the disc signal, that is, the circle The

role of the red, yellow and green traffic lights, which can be either straight or right, is generally 400mm.

3. Why is the traffic signal light in Zunyi, Guizhou, using a type 400 traffic signal?
Because the traffic light of the traffic signal is big, only after the area is displayed, it is clearer and clearer, so that the driver can see

it very far away.
As early as in some years, probably all of us used the 300 type traffic lights, but the 300 type traffic lights, after a long distance, his

visual effect is still much worse. Later, the national standard changed the 300 traffic lights to 400. Type traffic lights, it is really much

better than before.
Fourth, how to ensure the quality of traffic lights?

When our company is doing traffic lights, it is usually divided into three steps. Using these three steps to ensure the quality of our

traffic lights, the following small series will lead you to take a look at our three steps of traffic signal detection:
The first step is to connect the 12-volt voltage directly to the power-on test for 12 hours after the whole lamp board is completed.
The second step is to add the special power supply to the lamp board after OK, then install the lamp board power supply on the

wick, and then aging test for 24 hours;
In the third part, the wick is installed inside the casing, and the whole machine is equipped with a signal machine, which is normally

operated for 12 hours.
 After this three-step long-term test aging impact, then its quality is greatly improved, each step has a flat tube one by one inspection,

and then there will be a corresponding record
Traffic lights seem simple, but his security requirements are very high, a postcard from a city.
Traffic lights are broken, the city is in chaos, and drivers are afraid to go forward. For the people’s livelihood project, traffic lights are

a vital image project, so we never sloppy every step.
