PURPOSE: A stone lantern using sun light is provided to remove a foreign material without an additional power source by installing a brush which is rotated by wind. CONSTITUTION: In a stone lantern using sun light, a solar cell unit(40) is attached to the top surface of the stone lantern and converts sunlight into electricity. A charge unit stores electricity from the solar cell unit. An illumination unit(50) receives the electricity from the charge unit and radiates light. A foreign material elimination unit(60) includes a rotation shaft, a rotation force generator, and a brush. The brush is closely adhered to the surface of the solar cell and has a curved shape.
