LIGHT TUNNEL STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a light tunnel structure wherein light can be effectively made incident in a light tunnel and light emitted through the light tunnel can be uniformly emitted even when an optical axis and a center axis of the light tunnel device are not parallel to each other.

SOLUTION: The light tunnel structure 200 includes a plurality of reflectors 201 to 204 joined together to form the light tunnel 205. The plurality of reflectors 201 to 204 have edges at an end of the light tunnel structure so that not all of the edges at the end are positioned at the same plane.
