Solar street lights consist of solar panels, LED light heads, lamp posts, batteries, and controllers. Among these five components, do you know which part determines the lighting duration of solar street lights? Many would think it’s the battery since everyone knows that the battery powers the light source, but they often overlook the solar street light controller.
To begin with, it acts like the CPU of the solar street light, connecting the solar panel, LED light head, and battery. The solar panel charges, the battery provides power, and the LED light head performs various protective functions during operation. Its position is determined by the specifications and models of the solar street light. What role does it play in the entire solar street light?
First, it functions as the central processor of the solar street light, connecting with the solar panel, LED light head, and battery. The solar panel charges, the battery provides power, and the LED light head performs various protective roles during operation. There is also a question we addressed at the start. Why do many rural solar street lights not stay lit all night?
This is another function of the controller, which can adjust the lighting time of the LED head. Generally, the controller has four adjustable time periods and a dawn mode to freely set the turning on and off times. In rural areas, there are usually no pedestrians after midnight, so road lighting is not necessary. Additionally, the shorter the illumination time of the solar street light, the more costs can be reduced. This is why many rural solar street lights do not remain lit all night.
