The present invention relates to a light condensing lens and a solar light power generation apparatus using the same, and the light condensing lens comprises a main body unit, which is a plate type part made of a light transmittable material, elongated to a predetermined length along a central axis, and a refracting unit, which is a part made of a light transmittable material, provided at a lower surface of the main body unit and refracting light that has penetrated the main body unit, wherein the refracting unit includes a central part, a left part arranged at the left side of the central part, and a right part arranged at the right side of the central part, the left part and the right part include a plurality of refracting surfaces to be formed by elongating, along the central axis, a saw tooth-shaped cross section in a plurality of rows, the left part and the right part are shaped and arranged in a bilateral symmetry around the central part, and light radiated from an upper surface of the main body unit is condensed to a focusing region having a predetermined width while passing through the main body unit and the refracting unit, wherein the focusing region is formed so as to be long along the central axis. According to the present invention, a conventional complicated system having a structure in which a protective plate made of a tempered glass material is arranged on a lens array is different therefrom in that a lens sheet having a simple structure can be manufactured, thereby reducing overall manufacturing costs and preventing a concern for breakdowns. |
