PHOTOCONDUCTIVE MEMBER, LIGHT SOURCE DEVICE EMPLOYING THE PHOTOCONDUCTIVE MEMBER, LIGHTING DEVICE EMPLOYING THE PHOTOCONDUCTIVE MEMBER, AND LIGHT GUIDING METHOD EMPLOYING THE PHOTOCONDUCTIVE MEMBER

摘要

A photoconductive member (1) has a curved surface portion (12a) for totally reflecting the light from a light source (2) guided through an incident portion (11) and further reflecting the totally reflected light by a reflective surface before emission. Consequently, light can be emitted even from the curved surface portion (corresponding to the portion of conventional shape), and the photoconductive member can emit light from the entire surface in the light-emitting direction. A light source device, a lighting device and a light guiding method employing the photoconductive member are also provided.
