Does the Traffic Signal Light Use Low Voltage or High Voltage Electricity?

I believe everyone should know that although traffic signal lights are a kind of traffic facility tool for diverting traffic flow and improving road capacity, they also need electricity to operate. However, in the use of electricity, there are mainly two types: low voltage and high voltage. So, does the traffic signal light use low voltage or high voltage electricity?

Traffic signal lights are driven by high voltage electricity and controlled by low voltage electricity.

Low Voltage Electricity：

Low voltage electricity serves as a signal power. Generally, it refers to DC circuits, or audio, video, network, and telephone lines. The DC voltage is generally within 36V.

High Voltage Electricity：

High voltage electricity is used as a power source. Generally, it refers to the power part in the field of electrical engineering. It is characterized by high power, large current, and low frequency. The AC voltage is generally above 24V.

Any electrical equipment using AC power belongs to the category of high voltage electricity. Therefore, traffic signal lights are no exception.

In traffic signal lights, high voltage and low voltage do not simply refer to the voltage level or current magnitude of the power supply, but rather to the entire system. For example, lighting, air - conditioning, and power systems all belong to the category of high voltage electricity, while fire protection, security, and building intelligent systems all belong to the category of low voltage electricity.

Of course, high voltage and low voltage electricity are not completely independent. The operation of the low voltage system also requires power supply from the high voltage system, and many low voltage technologies and devices are also used in the high voltage system for automatic and intelligent control. Therefore, traffic signal lights are driven by high voltage electricity and controlled by low voltage electricity.
