Problems solved by technology

[0003] Existing solar LED street lamps all adopt the method of automatic switching. During the lighting period, the street lamps work with the same power. Since the solar energy itself generates very limited power, this method is likely to cause the limited electric energy not to be fully utilized, resulting in energy waste. The energy saving effect is not ideal

Description

technical field [0001] The invention relates to solar lighting technology, in particular to a solar street lamp with adjustable power and a power control method thereof. Background technique [0002] As the earth's resources become increasingly scarce, the investment cost of basic energy is rising day by day, and various hidden dangers of safety and pollution are ubiquitous. Solar energy, as an "inexhaustible and inexhaustible" safe and environmentally friendly new energy more attention. However, although solar energy is huge, it is very scattered, so solar energy is generally used for low-power power generation. At low power, the light efficiency of traditional light sources is very low, which is not suitable for application in solar lighting systems. In recent years, with the development of solar photovoltaic technology and the continuous progress of semiconductor light-emitting diode (LED) technology, the solar LED lighting system composed of solar panels and batteries ...
