<p>The present invention relates to a lighting using an optical fiber, and comprises: a irradiator for irradiating laser beams; a circular optical cable, which is connected to the irradiator, for transmitting light; the optical fiber which is formed in the shape of a semicircle and is provided with a cable coupling portion to which the optical cable connects; a refraction portion, which is provided on the flat portion of the optical fiber, in which protruding refraction portions and refracting grooves are alternately formed; and a barrier film which is provided on the circumferential surfaces of the cable coupling portion, the refracting portion, and the optical fiber. The present invention allows irradiation of light through a semicircular optical fiber on one side of the optical cable having a diameter which is bigger than that of the optical cable, and has the advantage of efficient use of light by allowing the light that passes through the inside of the optical fiber to be reflected by the refracting portion by providing the refracting portion on the flat surface of the optical cable having a semicircular form, so as to irradiate all of the light that passes through the inside of the optical fiber through the semicircular circumferential surface.</p> |
