As a lamp energy saving and emission reduction in the new century the important power of the original, solar energy has been welcome by many consumers. When demand for power supply solar lighting system, it is safe and efficient solar led street lamp lighting source voltage and current. Led, solar street light system safety and energy saving for the things of people and life supplies of clean and environmental protection of green lighting. However, due to extreme solar photovoltaic power generation system of the input energy is not consolidated, with configuration of battery system is a normal. Solar street light is no exception. Have a need to configure the battery. Battery capacity of selected at ordinary times comply with the following principles first, solar led street lamp to store as much as possible the sunlight solar energy battery components, at the same time meet the requirements of lighting at night. At the same time, they also can store up to meet the demand of continuous rainy day lighting of electricity. The in the applications of led solar street light, it is necessary to pay more attention to security issues, because it is the exercise of solar panels to absorb solar energy, might as well get a room if the battery problems communication confound provoked suddenly damaged lamps and lanterns.
