Solar traffic signal blinkers function in 5 ways:
Solar panels use silicon cells to convert sunlight into DC power. The solar panel's electrical output relies on sunshine.
The battery stores the DC electricity generated by the solar panel. The battery is typically a lead-acid battery or a lithium-ion battery.
The charge controller ensures that the battery does not overcharge or discharge too much. This helps to extend the life of the battery.
The LED light is a light-emitting diode that converts electrical energy into light. The LED light is typically red or yellow, and it blinks at a regular interval.
The solar traffic signal blinker is a self-contained unit that does not require any electrical wiring. This makes it easy to install and maintain.
