Abstract
In the 21st century, with the intensification of the world energy crisis, solar energy is considered as the most common and clean energy. It is focused on by human with its advantages as below: bringing little pollution to the air, hardly destroying the ecology, causing no “greenhouse effect”. At the same time, LED has the advantages of high efficiency, energy saving, long life, environmental protection, has already been widely used in various lighting situations as a regeneration of the green Lighting source.
In order to respond positively to the call of national energy saving and emission reduction and developing low-carbon economy, for the purpose of its practical application, from the starting of the photovoltaic properties of solar cells, rounding the solar photovoltaic technology and LED lighting technology, the solar LED lights systems is designed to meet the use of road lighting. The system consists of solar cells，batteries，controller，LED light source and constant current drive circuit and other components. The solar silicon photovoltaic panels convert solar energy into electrical energy stored in batteries, which provides power for the entire system.
