Abstract
A lighting system includes a housing, a light source, an optical member, and a shooting unit. The housing is mounted on an inner wall surface of a tunnel provided along a road. The light source is provided for the housing to emit lighting light. The optical member is provided for the housing to receive the lighting light incident thereon. The shooting unit is provided for the housing. The optical member causes a first bundle of rays to emerge toward the road and also causes a second bundle of rays to emerge toward the inner wall surface. The shooting unit shoots at least a part of an irradiation range where the inner wall surface is irradiated with the second bundle of rays.
