Patent ID: 8545078

Claim:
A solar lighting apparatus using optical fibers to transmit solar light for illumination, comprising: a support frame installed under a ceiling of a place to be illuminated; a plurality of optical fibers inserted through and fastened to the support frame, the optical fibers being spaced apart from each other at regular intervals; a hybrid solar light diffuser coupled to a lower portion of the support frame, the hybrid solar light diffuser comprising: a diffusion plate; and a plurality of diffusion lenses provided on the diffusion plate at positions that are spaced apart from each other at regular intervals and correspond to the respective optical fibers, a number of diffusion lenses being equal to a number of optical fibers, each of the diffusion lenses having a width increasing from a top thereof to a bottom, with an incident depression formed in an upper end of each of the diffusion lenses that is spaced apart from an end of the corresponding optical fiber, the incident depression diffusing and refracting solar light, and a reflective surface formed on a circumferential outer surface of each of the diffusion lenses, the reflective surface diffusing and reflecting solar light; and a reflective sheet applied to a lower surface of the support frame.
