according to introducing, solar street lamp is mainly composed of four parts: pv modules convert light energy into electrical energy, light-emitting diodes, solar cells, solar battery charge and discharge and control of the controller. Photovoltaic modules to absorb light during the day, convert solar energy into electrical energy storage in solar cells, to discharge lighting when it is dark at night. Sunny days commonly, under the ideal light intensity, full of electricity, as long as four hours per charge can guarantee up to five days after the completion of the above, continuous rain 3 days also can work normally. To explore three: street light control switch? The street lamp switch how to control? When street lamps are installed on the controller to play a role, according to the requirements of different lights can be designed for electric or time control, not only the storage battery charging and discharging time controlled, LED street light, the intensity of discharge size can also control. In addition, due to the installation location of the environmental indicators, solar street lights will be effective daylighting can produce a considerable impact. Researchers also can be used according to the daily lighting time, to ensure the maximum number of days of a lighting and street light bulbs, etc. , used according to demand to design the size of the battery. In the Shanghai area, for example, the year the average effective sunshine time is about 2. 5 - 3 hours, if you choose to install in the wind big coastal area, effective illumination time is not very regular, can special take this factor into consideration when installation, will break through the original continuous lighting time 7 day light lamp cap design, do 15 days. This also means that as long as the continuous rainy weather is no more than 15 days, don't have to worry about solar street light 'blackouts'.
