In the context of energy shortages, with the maturity of solar photovoltaic devices and high-power LED devices, solar street lights are increasingly widely used. The solar street light controller is an important component of the LED solar street light system, and its performance directly affects the functionality of the entire solar street light system.
The solar street light system consists of solar panels, LED street light controllers, lead-acid batteries, and LED street light modules. Throughout the system, the solar street light controller occupies a core position; its performance directly determines the overall system’s capabilities. This type of controller is equipped with multiple protection functions, including battery overcharge protection, discharge protection, solar panel overvoltage protection, and load short circuit protection.
According to design requirements, the controller decides on the charging mode based on the battery state when charging starts. If the battery is in a discharged state, it enters boost charging mode; if the battery is in an under-voltage state, it enters direct charging mode; if the battery is in float charge mode, it stays in float charge mode. If the battery itself is over-voltage, it remains in an over-voltage alarm state. After completing boost or direct charging, the controller transitions to float charge mode. When the battery voltage drops below the direct charging return point due to load consumption, the controller re-enters the direct charging mode. At this time, if the load continues to consume power and the solar panels cannot provide sufficient charging energy, causing the battery voltage to continue to fall to below the under-voltage or discharge point, the solar street light controller enters discharge protection, disconnecting the load and transitioning to boost charging mode.
In practical applications, people often want street lights to reduce brightness in the late night hours. The solar street light controller achieves this effectively. The purpose of this approach is twofold: first, to save energy, and second, to extend the lifespan of the solar street light while maintaining the same color temperature at different brightness levels. Previous street lights lacked power control or dimming capabilities. Thus, this method can achieve these objectives.
