Abstract

The present invention provides a light focusing apparatus comprising: a Fresnel lens having a predetermined focus; a first reflector spaced apart from the Fresnel lens, and formed on a first virtual parabolic trajectory having the same focus as that of the Fresnel lens; and a second reflector formed on a second virtual parabolic trajectory which is spaced apart from the first parabolic trajectory, and which has the same focus as those of the Fresnel lens and the first parabolic trajectory, wherein the second reflector is spaced apart from the Fresnel lens and the first reflector. The present invention also provides a solar energy generating apparatus. The light focusing apparatus of the present invention minimizes loss area (RA), minimizes the size thereof and the size of the solar energy generating apparatus, and improves the light focusing rate.
