What are the functions of the working principle of solar street lights

The working principle of solar street lights, including light control and time control, as well as the function of the controller.

‌. Core working principle ‌
‌Light Energy Conversion and storage ‌




‌. During the day, solar panels convert light energy into electric energy through photovoltaic effect, which is transmitted by the controller to the battery for storage ‌.
The controller monitors the battery voltage in real time, automatically manages the charge and discharge status, and prevents overcharge or overdischarge ‌.
‌Light control and time control mechanism ‌

‌Light control principle ‌ : automatically control the switch of lamps by detecting the intensity of ambient light. When the light weakens to the threshold value (such as dark), the controller starts to discharge and the road light will turn on; Stop discharging when the light increases (such as dawn) and switch to charging mode ‌.

‌Time control principle ‌ : preset fixed lighting duration or switching time. For example, set the lights to turn off automatically after 4 hours, or adjust the operating period according to the season ‌.

Light control is to control the switch by detecting the intensity of light, and time control is to set the time. The controller charges during the day and discharges at night, combining the two control methods. For example, light control on the light + time control off the light.

Time interval dimming ‌ : the night is divided into multiple periods (such as peak period, low period), dynamically adjust the brightness to save energy ‌.
‌ Morning light mode ‌ : light up for a short time in the early morning (such as 1-2 hours) to adapt to specific needs .

Key technical support of controller ‌
‌ Hardware configuration ‌

Dual MOS control loop ‌ : reduce circuit voltage loss, improve charging efficiency (50% energy saving compared with diode scheme) ‌.
Temperature compensation chip ‌ : real-time monitoring battery temperature, adjust the charging voltage to prevent high temperature overcharge or low temperature undercharge ‌.
