According to the high-efficiency energy storage circuit and the solar street lamp, the power density of the energy storage circuit is improved, the service life of the energy storage circuit is prolonged, the charging and discharging efficiency and the current utilization rate are improved, and dependence on the environment temperature is reduced.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of street lamp lighting, and in particular to a high-efficiency energy storage circuit and a solar street lamp. Background technique [0002] With the development of social economy and the improvement of living standards, urban construction has undergone rapid changes, especially the progress in road lighting construction is obvious. Every night, the streets and alleys of the city are brightly lit, which provides convenience for people's production and life. At present, many street lamps adopt solar charging technology to achieve the purpose of saving energy. However, in some high-latitude regions, due to the limited duration of sunlight and weak sunlight intensity, combined with some defects in the current design, the absorbed light energy has not reached an ideal state in terms of storage and use efficiency. The power density of the energy circuit is low, the service life is sho...
