LIGHT-CONDUCTING APPARATUS

摘要

A light-conducting apparatus includes a light source, a light-conducting member and a light-reflecting structure. The light-conducting member includes a ring-shaped portion, a light-receiving surface and a radially outwardly bulged portion. The ring-shaped portion extends continuously over an entire circumference of the ring-shaped portion in a circumferential direction of the ring-shaped portion. The light-receiving surface causes light from the light source to enter the light-conducting member through the light-receiving surface. The radially outwardly bulged portion is bulged radially outwardly from the ring-shaped portion and causes the light having entered the light-conducting member through the light-receiving surface to enter the ring-shaped portion in one direction in the circumferential direction of the ring-shaped portion. The light-reflecting structure reflects a portion of the light having entered the light-conducting member through the light-receiving surface and causes the reflected light to enter the ring-shaped portion in a direction opposite to the one direction in the circumferential direction of the ring-shaped portion.
