PROBLEM TO BE SOLVED: To pass the irradiation light of a lighting apparatus or the irradiation light of a lighting apparatus, which is reflected by a shape member, thereby to add a variation to the performance of a light and to improve the feasibility of a maintenance management when the collaboration of the lighting apparatus and a housing material is advanced.SOLUTION: A diffuser panel 15 to be attached to a reflection shape member 1A is arranged at the position, where the light of a lighting apparatus 2 reflected by a first face 303 of a reflection surface 30 passes, and the light having passed is reflected by a second face 304 of the reflection surface 30 and is radiated. In the diffuser panel 15, specifically, the end edge of the diffuser panel in the longitudinal direction is positioned in a fitting groove part 322 formed in the outer side of a slide part 321 of the reflecting shape member 1A, and the end edge of the other longitudinal direction is positioned in a fitting groove part 323 formed on a boundary line dividing the plain face 301 of the reflection surface 30 into substantially a half.SELECTED DRAWING: Figure 32 |
