The component that functions like the power converter is the driver in LED street lights. When the circuit is connected to the high-voltage urban grid, the driver can change the voltage to a lower one and make the current constant. And the value can be changed according to the change in the forward voltage. The switching power supply is the most popular type of driver for LED street lights. It applies the technology of PWM to keep the voltage and current constant.
