Zusammenfassung:	A light focusing lens is provided to focus light of a wide area and shorten a focusing distance through a dome or half cylindrical shape, thereby improving energy usage efficiency. A light focusing lens is made of transparent materials having superior light transparency. The first lens is in the center of the light focusing lens. The second lens is adjacent to the first lens. The first and second lenses have the same focus. The third, fourth, and the N lenses have the same focus as the first lens. The first, second, third, fourth, and the N lenses are all adjacent. An upper surface(1) of the lens is projected in a normal convex lens. A lower surface is cut along with a refraction path of incident light(2). Therefore, the lens has a saw toothed shape. The first and N lenses are provided through a dome shape lens.
