PROBLEM TO BE SOLVED: To provide a lighting system in which light guiding efficiency is prevented from being reduced and lighting efficiency is improved easily while reducing lowering in the appearance of a building with installation of the lighting system, by forming no through-holes or the like penetrating the indoor side and the outdoor side of the building.SOLUTION: A lighting system comprises a lighting panel 3 including a light incident surface 3a, a light irradiation part 15 which irradiates the indoor side of a building 30 with light taken by the lighting panel 3 from an opening part 35 of the building 30, and a transmission part 11 which transmits the light from the lighting panel 3 to the light irradiation part 15, and the transmission part 11 is disposed in a location at the indoor side of an outer wall member 33 for the building 30. Thus, a change in appearance of the building 30 with installation in the transmission part 11 can be reduced, and the appearance of the building 30 is unlikely to be reduced from the original state. |
