The invention provides an automatically controlled solar street lamp which comprises a solar panel, a charge and discharge control circuit, a storage battery, a street lamp control processor and a light-emitting diode (LED) street lamp load which are connected mutually. The automatically controlled solar street lamp has the advantages of being long in service life, high in efficiency, low-temperature resistant and green and environment friendly. The automatically controlled solar street lamp has functions of preventing the storage battery from being over discharged and charged; as a charging state of the storage battery is usually low in several months of insufficient solar irradiation, the terminal voltage of the storage battery is low during discharging, and accordingly, loaded work currents and the power are small, and a system can work for a long time; otherwise, when the solar irradiation is sufficient, loaded work currents and the power are large, and the street lamp is bright.
Description
technical field [0001] The invention relates to the technical field of street lamp equipment, in particular to an automatically controlled solar street lamp. Background technique [0002] In recent years, energy and its related environment have become the focus of attention of countries all over the world, and all countries are solving energy and environmental problems based on their own national conditions. For my country, due to the shortage of per capita energy resources, especially oil, gas, and water, the environmental capacity is also limited, and the ecology of the western region is fragile. There is room for survival in Wandaishengxixi. In a sense, the development of human society is inseparable from the emergence of high-quality energy and the use of advanced energy technologies. In today's world, energy development, energy and environment are issues of common concern to the whole world and all mankind, and are also important issues for my country's social and econ...
