  The traffic light is a signal light that controls the traffic operation, generally consisting of red light, green light and yellow light. The red light means stop , the green light means the pass , and the yellow light means the warning   and observation.   O rigin of traffic lights : In 1858, red and blue mechanical wrench-type signal lights with gas as the light source were installed on the main streets of London, England, to direct the passage of carriages. This is the first traffic light in the world. In 1868, British mechanical engineer John Peake Knight  installed the world's first gas traffic light on the square in front of the Houses of Parliament in Westminster, London. It consists of red and green two rotating square glass lanterns, red means "stop", and green means "attention". On its 23rd day of operation, a gas light suddenly exploded, killing a policeman on duty on the spot, and it was canceled.   In 1914, the traffic lights for electrical activa

S o lar traffic lights are powered by solar energy, the cost of operation is almost zero, and so it is now gradually recognized. Don't avoid  its inspection and maintenance   after installation: 1. Do   the traffic signal components meet up specification ? If   not then , it is likely to cause a short circuit in the internal circuit, or even more serious things, so be sure to check whether the specifications of all parts are qualified. And also pay attention to whether the position of his light pole is more appropriate. 2. Are the angle and inclination of the battery components of the solar traffic signal installed correctly? It must be known that there cannot be too many obvious obstructions between these two parts, and its light pole must be at a vertical angle to the ground, so as not to cause the solar traffic light to lean  easily. Moreover, the settings in the controller must also meet the requirements, otherwise, it is easy to lose control, and there will be abnormal phenom

Importance’s of traffic signal light to build up road traffic management, reduce the occurrence of traffic accidents, improve road use efficiency and improve traffic conditions. I t ’s suitable for intersections such as crosses and T-shaped intersections. Travel in a safe and orderly manner. The material analysis of traffic signal light housing   given bellow 1.  Common housing materials for traffic lights:   Mainly divided into four categories: 1.1 PC material : 1.2 Die-cast aluminum : 1.3 Profile aluminum material : 1.4 Sheet metal material : 2. Advantages and disadvantages of various traffic signal materials: 1.1 PC material: Advantages : Relatively   low mold cost, light weight, convenient high-altitude operation, good safety, and no need for additional lightning protection measures, one-time molding of the mold, very convenient assembly and installation, waterproof and dustproof the effect is better than the others. If the housing  made of PC raw material is added with anti-UV ma
