PROBLEM TO BE SOLVED: To provide desirable external appearance without exposing piping to the outside of a wall by covering an internal corner part where mutually orthogonal two side wall surfaces cross each other with a cover plate, arranging a piping space between the internal corner part and the cover plate, arranging a shielding plate on the outside of the cover plate, and arranging a luminaire between the cover plate and the shielding plate. SOLUTION: A piping space 21 is constituted by installing a resin cover plate 3 in an internal corner part of two side wall surfaces 2 and 2 of a room in a building. Piping 4 is arranged in this. A shielding plate 5 is installed at an interval on the outside of the cover plate 3. A fluorescent lamp (a luminaire) 6 and its reflecting plate 61 are arranged between the cover plate 3 and the shielding plate 5. For example, metal such as a galvanized iron plate, stainless steel and aluminium and a synthetic resin such as a hard vinyl chloride resin and polyethylene can be used as a construction material of the cover plate 3. For example, metal and, resin can be used as a construction material of the shielding plate 5. A semitransparent material may be used as the shielding plate 5 to exhibit an indirect illumination effect. |
