PURPOSE:To improve apparent atmosphere by boring a number of through-holes in a plate material, and arranging one end of an optical fiber the other end of which is connected to a light source box in each through-hole to form an optional pattern. CONSTITUTION:A number of through-holes 2 are bored over the whole surface of a ceiling plate 8 as a building panel A formed in a doom. The end part of an optical fiber 4 delivered from a light source box 9 provided on the ceiling back side is arranged in each through-hole 2, and the end part of the optical fiber 4 is made to emit light to form a pattern. A light shielding plate 10 having an arc opening 10 is arranged below the ceiling plate 8, and a lighting equipment 11 is arranged between the light shielding plate 10 and the ceiling plate 8. Thus, a pattern 3 such as a constellation pattern 3a can be expressed on a ceiling surface 1 with a feeling of distance. |
