1. Make the current output constant. For LED lights, it is necessary to achieve constant current or current limiting to make them work normally through technical means, but generally a driving power supply is often added to perform constant current on the LED, but this also increases its power loss.
2. Control the control period. The solar street light controller can control the output current for a period of time through a preset period of time.
3. Adjust the output power. In general solar street light applications, the power should be set, such as adjusting the street light to 30W in the early morning and 15W in the late night to save energy. In this way, the overall configuration and budget of the battery and solar panel can be realized by adjusting the current, and it is also extended the life of LED lights.
