What are the reasons for the short circuit of road traffic signal lights?

LED traffic signal lights are a type of traffic lights used to allocate effective right-of-way to conflicting traffic flows, so as to improve road traffic safety and road capacity. LED traffic signal lights are the signal lights that command traffic operations, generally consisting of red lights, green lights, and yellow lights. The red light indicates no passage, the green light indicates permission to pass, and the yellow light indicates a warning. Traffic signal lights may also malfunction during use. Then, what are the reasons for the short circuit of road traffic signal lights?

(1) After the battery is discharged, it is not sufficient to automatically recover; if the load power exceeds the rated power, reduce the electrical equipment and wait for a long time for recovery. In the case of a load short circuit, it can generally be automatically recovered the next day after the fault is eliminated. At this time, please check whether the power supply equipment is connected correctly and reliably.

(2) Due to improper installation or the fact that the circuit board of some controllers has not been treated with three-proof paint, rainwater may flow into the traffic signal light controller along the external connection wires of the controller terminals, resulting in a short circuit. Therefore, during construction, attention should be paid to bending the internal connection wires of the controller terminals into a "U" shape and fixing them. The connection wires exposed outside should also be fixed in a "U" shape. In this way, rainwater cannot pour in and cause a short circuit of the controller. Waterproof glue can also be applied at the interface of the internal and external wires to prevent water ingress.

Through our analysis of the reasons for the short circuit of traffic signal lights, it is found that if we want to avoid this problem, the most important thing is to do a good job in the installation of the equipment and the waterproof work. Only in this way can we make better use of this equipment and relieve traffic pressure.

The above is an introduction by Starlight Road about the reasons for the short circuit of LED traffic signal lights, hoping to provide a reference for everyone.
