LIGHT TRANSMITTING APPARATUS

摘要

A light transmitting apparatus of the present invention has cylindrical ducts in which the light transmits, the ducts having a light reflection effect in an inside thereof; and a bending portion having a light reflection effect in an inside thereof, a cross section of the bending portion is elliptical; wherein the bending portion connects one of the ducts with the other of the ducts. Accordingly, the present invention can improve the light transmitting efficiency of the bending part of the duct for transmitting the light.
