Integrated solar street lamp is suitable for rural areas. However, the integrated solar street lamp also has some shortcomings. For example, because of the integration, the space is limited, the power of the light source must be very small, and the capacity of the solar panel and solar cell is also relatively small, leading to the dark integrated solar street lamp. Unlike conventional solar street lamps, integrated solar street lamps will be scrapped directly once broken, and the later replacement cost will be great, while conventional solar street lamps have a very long life of solar panels and light sources, and only need to change the battery. When night comes, it is necessary to light the street lamps to provide light for passers-by. Traditional street lamps used in the past can also bring light, but they are not durable and have a disadvantage in energy saving. Solar street lights are now widely used. At the same time, one-time installation, no additional maintenance costs, more easy to use.
