The specific working principle of the energy-saving street lamp head is as follows:
the voltage of the photovoltaic cell 104 is detected in real time by a voltage detection device according to the rule that the voltage of the photovoltaic cell 104 is larger under strong light in sunny days and smaller under weak light in rainy days and the voltage of the photovoltaic cell 104 is smaller when the solar cloud layer is too thick, and the detected voltage value is transmitted to the control device 103 and the solar controller 105 so as to excite the photovoltaic cell to start corresponding functions.
When the voltage value detected by the voltage detection device is greater than or equal to the first set value, the control device 103 controls the solar controller 105 to operate, and starts a solar charging mode under strong light.
As a specific embodiment, when the solar controller 105 selects the MPPT controller, the MPPT controller automatically tracks and charges the energy storage device 102 by using the maximum power tracking point, so as to ensure that the energy storage device 102 obtains the maximum energy from the photovoltaic cell 104, ensure the energy storage under strong light, and further supply power to the light source 101 by the charged energy storage device 102.
When the voltage value detected by the voltage detection device is smaller than the first set value, the control device 103 controls the solar controller 105 to stop working and controls the configuration switch 106 to start working to start the intermittent pulse weak light charging mode because the charging voltage is smaller and the energy storage device 102 cannot be directly charged.
