Many people have seen municipal LED solar streetlights illuminating the streets and alleys automatically at dusk. However, there is a curious question: how do these LED solar streetlights know that it is dark? It seems as though someone is controlling them. This functionality is referred to as light control in the solar energy industry. As the name suggests, light control automatically connects the circuit and provides power to the LED streetlight head when the ambient light reaches a certain threshold.
Light control primarily consists of two important components: the solar streetlight controller and the solar panel. We know that solar panels are used for generating electricity, and the voltage and current at the output terminals of the panel are determined by the strength of the external light. In other words, when the light is strong, the voltage of the panel is high; when the light is weak, the voltage is low. The intelligent system in the solar streetlight controller can sense the changes in the output voltage of the solar panel.
When the intelligent streetlight controller detects that the voltage from the solar panel falls below a certain set value, it automatically turns on the switch for the LED streetlight, illuminating it. Conversely, when the voltage at the terminals of the solar panel exceeds a predetermined value, the controller will turn off the LED light. This functionality is referred to as light control of the solar streetlight. This explains why LED solar streetlights automatically turn on at night.
