An integrated solar street light system which combines the green-energy parts of solar panel, LED lamp and the Li-Fe battery into a single product. This all-in-one product, together with a motion detector, offers a solution of low-energy consumption, long-lasting and high-luminance as well as free maintenance for at least five years. The intelligent controller and sensor meet different control requirements, and at the same time, Made up with integrated parts (solar panel, lithium battery , LED light source, controller and PIR sensor) and the light pole. The solar panel converts sunlight into electricity and stored in lithium battery via controller, the LED light will work in night automatically by PIR sensor control, and provide light for the darkness area, the PIR system can save the energy when the lighting is not necessary.
