Solar lighting with automatic opening and closing function of a mobile solar lights, the night comes (5:30 in winter, summer 7:30), solar lamps turn on automatically in the morning solar lamps turn off automatically, without personnel to manage and maintain. It works price of solar lights, when the sun light shines silicon solar panels, photo-generated electron - hole pairs in the battery built-in solar billboard lighting under the influence of an electrostatic field, due to the electron and hole zoning different The charge has been separated on both sides of the formation of 'the photovoltaic', that 'the photovoltaic effect'. The working principle is that when the sun light shines silicon solar panels, photo-generated electron - hole pairs in the battery built under the electrostatic field, due to the electron and hole with different charge points are formed on both sides of the separation 'the photovoltaic', that 'the photovoltaic effect'.
