PURPOSE: An LED illumination lamp using solar cell is provided to offer enough generation efficiency by using only solar rays without supply of other special electric power. CONSTITUTION: A photoelectric transformation part (210) is arranged at an upper end where solar rays are directly radiated. A power storage part (230) stores the power generated from the photoelectric transformation part and prevents overcharge. An LED illumination part (250) is turned on by receiving electric power from the power storage part and is arranged at the lowest end for illuminating the ground. A cover (200) whose part is made of a transparent or a semi-transparent material covers the photoelectric transformation part, the power storage part and the LED illumination part. The cover comprises an upper cover and a lower cover, and a rib is formed at an inner side of one between the upper cover and the lower cover. An insertion recess is installed at either the upper cover or the lower cover. A sealing member is installed in the insertion recess. |
