PROBLEM TO BE SOLVED: To provide a photoconductor for lighting that mixes light beams from a plurality of light sources, making a uniform brightness and a color tone and sending out as parallel light beams or intended diffuse, condensing light beams. SOLUTION: (1) A lens is provided on the incident face and the exiting face of the photoconductor, with these incident face lens and the exiting face lens set to essentially share a focal point. (2) In the middle between the first photoconductor having the incident face lens and the second photoconductor having the exiting face lens, there is provided a space that can increase/decrease a relative distance between the first and second photoconductors.
