[0038] The following is combined with Figure 1-3 This application is described in further detail.

[0039] The present application discloses a solar energy and mains electricity complementary street lamp. Figure 1 and Figure 2 The solar energy and mains electricity complementary street light comprises a street light body 1, a solar photovoltaic panel 2 installed on the top of the street light body 1, an LED lamp 3 installed on the top of one side of the street light body 1, a photoresistor installed on the side of the street light body 1, and a solar controller, a battery and a mains electricity charger installed inside the street light body 1.

[0040] The solar photovoltaic panel 2 is used to receive sunlight and convert it into electrical energy. The solar controller is connected to the solar photovoltaic panel 2, the battery, the LED lamp 3 and the AC charger through a cable. The battery is used to store the electrical energy generated by the solar photovoltaic panel 2, and the LED lamp 3 is used to provide lighting; the photoresistor is used to control the on and off of the LED lamp 3 according to the light intensity, and the photoresistor is electrically connected to the solar controller; the AC charger is connected to the AC power supply and the battery through a cable.

[0041] Under normal working conditions, the solar photovoltaic panel 2 converts the received sunlight into electrical energy and transmits it to the solar controller through a cable; after the solar controller monitors the output voltage and current of the solar photovoltaic panel 2, it controls the charging process of the battery to ensure that the battery obtains an appropriate amount of charge and prevents the battery from being overcharged or undercharged; at the same time, the solar controller also monitors the voltage and capacity of the battery and controls the lighting of the LED lamp 3 as needed.

[0042] When solar energy is insufficient, the solar controller starts the AC power switching function according to the preset logical judgment conditions. Specifically, the solar controller monitors the output voltage and current of the solar photovoltaic panel 2, and determines whether the current solar charging is sufficient; if the solar charging is insufficient, the solar controller automatically switches to the AC charging mode according to the set conditions. At this time, the AC charger starts working, converts the AC power into a DC voltage, and connects to the battery for charging through a cable. In the AC charging state, the solar controller will give priority to solar charging. Once the solar charging is sufficient, the solar controller will automatically switch back to the solar charging mode. Thus, by switching between solar energy and AC power, the stable operation and lighting effect of the street light system are guaranteed.

[0043] Furthermore, through the light-sensitive characteristics of the photoresistor, the solar controller can monitor the ambient light intensity in real time and control the on and off of the LED lamp 3 according to the set threshold. When the ambient light intensity is lower than the set threshold, the solar controller controls the LED lamp 3 to light up; when the ambient light intensity is higher than the set threshold, the solar controller controls the LED lamp 3 to turn off.

[0044] In this embodiment, the battery uses a lithium-ion battery instead of a traditional lead-acid battery. The lithium-ion battery has the advantages of higher energy density, lighter weight, and longer service life.

The battery management module monitors the voltage and capacity of the battery, and controls the charging and discharging process of the battery as required. The lighting control module controls the on and off of the LED lamp 3 according to the photoresistor. The mains switching module automatically switches to the mains to charge the battery when the solar energy is insufficient, and switches back to the solar charging mode when the solar energy is sufficient.
