<p>PURPOSE: An LED street lamp system using sunlight is provided to light a street lamp using a natural energy by generating power from sunlight, natural energy, in inclement weather. CONSTITUTION: A LED lamp(400) is protruded to a lateral part of a street lamp. A solar cell(200) generates power using sunlight on the top of the street lamp. A charge unit(500) stores power generated by the solar cell. A control device is built on the top of a control box for controlling an electrical system of the street lamp. The control device includes a control means(320) controlling turning on and off of the LED lamp. A micro current collection means(340) collects micro currents. The micro current collection means charges the charge unit through discharging when a predetermined amount is charged.
