    FIELD
    The present invention relates to a new energy street light, in particular to an automatic charge-controlled solar energy saving street light.
    BACKGROUND
    Generally, the street lighting is powered by the municipal power supply. Due to the large number of street lights, wider distribution area and longer lighting time, for the municipal department, the energy consumption of street lights is very large even if the energy-saving and environmental-friendly LED street lights are used. At the same time, the street lights also require the municipal department to arrange special staff for management, and labor costs are therefore relatively high.
    In the prior art, there are also some technical solutions that use natural energy for power supply. For example, a solar cell is used as a power supply unit of an LED street light, and the solar energy is converted into electric energy to be stored in a storage battery. When the LED street light is turned on, it will be powered up by the storage battery.
    However, the LED solar street light in the prior art still suffers from the following defects: 1. solar power supply unit itself is not reasonably designed with relatively high energy consumption; 2. in certain time and area, insufficient solar energy may easily lead to insufficient power supply of LED lights; 3. there is still no solution to the technical problems of street light switches cannot be automatically controlled.
    The patent 201510638402.9 proposes a solar LED street light with automatic charge control as a lighting method. The method includes providing an automatic charge-controlled solar LED street light, which includes an LED light tube, a Freescale MX6 processor, a real-time clock chip, a photovoltaic cell and a lead-acid battery. The photovoltaic cell charges the lead-acid battery; the charged lead-acid battery provides power supply to the Freescale MX6 processor, real-time clock chip and LED light tube; and the Freescale MX6 processor is connected with the real-time clock chip and controls the charging of the lead-acid battery by the photovoltaic cell according to the current system time provided by the real-time clock chip. Through the invention, the LED street light is charged by the most suitable charging method in different time periods, and the automation level of the LED street light is also improved. However, in the case of inadequate lighting, the system cannot work, it is difficult to meet the diversified needs of street lights in practical applications.
    The patent 201510645256.2 proposes an automatic insecticidal LED solar street light which comprises an LED light tube, a main controller, a target identification device, a photovoltaic cell and a lead-acid battery. The photovoltaic cell charges the lead-acid battery; the charged lead-acid battery provides power supply to the main controller, the target recognition device and the LED light tube; and the main controller is connected with the target recognition device to determine the distribution of the leaves near the LED street light according to the recognition results of the target recognition device. Through the invention, the leaf distribution detection and the automatic charging function are taken into account at the same time. But the use of the patent is of poor practicability due to the fact that it can neither achieve automation control of the street light nor intelligently control the street light in different time periods.
