Solar street lights are now well known by more and more people. The characteristics of solar controllers for solar street light power generation systems are believed to be unknown to many people.

The controller plays a vital role in the use of solar street lights, and its characteristics are mainly reflected in three aspects. as follows:

First: Control the output period The solar controller can set the time period, and the output current starts to work when the set time period is reached. Intelligent control is achieved without manual monitoring operations.

Second: guarantee current constant current output Because the LED itself needs constant current or current limiting through technical means, otherwise it will not work normally. The general LED lamp usually adopts a driving power supply for constant current of the LED, but this requires power loss, which makes the independent driving power supply more power-consuming, so this method is not preferable.

Third: adjustment of output power In the application of solar street lights, the power is adjusted. Adjusting the power can control the brightness of the LED light. For example, the street light is adjusted to 30W in the early morning and 15W energy saving in the late night. This locks the current to meet the lighting requirements at night, and saves the overall configuration and budget of the battery and solar panel. Greatly and effectively extend the life of LED lights.
