Construction of the urban development in the future, now the lamp on too much, the use of solar led street lamp every day for the country save electricity quantity is considerable. Led solar street light overall plan basically took into account the use of each link; Photovoltaic modules of wattage selection plan and battery capacity selection plan adopted now the general planning method, planning more scientific; Wind planning from the battery components support and two pieces of light pole made comprehensive analysis; Overall structure of pure and beautiful about led solar street light; Practice proves that good fit between each link.
