As shown in FIG. 2, the opening 2a is a large opening extending from the floor F1 to the ceiling 3 of the living room 21, and a transparent surface material 2e such as a transparent glass is installed in the opening portion to form the living room 21. , The terrace 22 can be widely viewed. The height of the ceiling 3 and the height of the eaves ceiling 4 of the living room 21 are formed substantially the same, and the height of the floor F1 of the living room 21 and the height of the floor F2 of the terrace 22 are formed substantially the same. Thus, it is possible to obtain a feeling as if the living space 21 is a space having a continuous depth to the terrace 22.

  Next, the lighting installation structure 1 around the ceiling 3 will be described with reference to FIGS. As shown in FIG. 4, the lighting installation structure 1 has a plate-shaped ceiling finishing material 31 having a slit 3 b penetrating in the thickness direction, with a lower end surface forming a ceiling surface 3 a of a ceiling 3, and The illumination box 5 has a concave groove shape in a sectional view and is arranged in such a manner that an opening portion of the concave groove 51 is positioned in the groove, and a lighting device 6 fixed in the concave groove 51 of the illumination box 5.

  As shown in FIG. 3, a ceiling S is formed between the ceiling 3 and a structural material X such as an upper floor or a roof, and the ceiling 3 is hung on the structural material X by a hanging metal fitting. . As shown in FIG. 4, the ceiling 3 includes a ceiling finishing material 31, a ceiling base material 32 such as a plaster board installed on the side of the ceiling with respect to the ceiling finishing material 31, a ceiling finishing material 31 and a ceiling base material A long edge 33 for supporting the material 32.

  As shown in FIG. 5, the ceiling finishing material 31 is formed by fitting a plurality of elongated woodgrain boards 3c with woodgrain (not shown) along the longitudinal direction. The wood grain board 3c has a dowel groove 3d formed on one side surface and a dowel groove 3e formed on the other side face. The dowel groove 3d is fitted with a dowel groove 3e of a different wood grain board 3c. As a result, a so-called paneled panel material can be obtained. In the ceiling finishing material 31 formed in this manner, a slit 3b penetrating in the thickness direction along the longitudinal direction of the woodgrain board 3c is formed, and the first width W1, which is the width of the slit 3b, is different from the lighting fixture. The width of the slit 3b is substantially the same as the length of the lighting fixture 6, as shown in FIG.

  As shown in FIGS. 4 and 5, the lighting box 5 is an elongated wooden member having a concave groove shape in cross section for supporting the lighting device 6, with the concave groove 51 facing downward, and the concave groove above the slit 3 b. It is installed so that 51 opening parts are located. In the lighting box 5, the bottom surface 5a and the side surface 5b, which are the inner side surfaces of the concave groove 51, are blackened with paint, sheet material, or the like. Almost no. Further, the third width W3, which is the width of the bottom surface 5a of the lighting box 5 shown in FIG. 5, is wider than the first width W1 and the second width W2, and further, as shown in FIG. , The length of the slit 3 b and the length of the lighting fixture 6.

  As shown in FIG. 3, the lighting fixture 6 is a line lighting such as an elongated LED, and an electric wiring 8 connected to a lighting transformer (not shown) in the ceiling S is connected to one end in the longitudinal direction. The light can be turned on or off by turning on and off a hand switch (not shown) installed on the wall of the living room 21 or the like. The lighting fixture 6 is installed in the concave groove 51 of the lighting box 5 by the fixture 7 having a substantially concave groove shape shown in FIGS. The fixing member 7 is a member having a slight elasticity formed of a hard resin or a metal, and has a fixing piece 7a fixed to the bottom surface 5a of the lighting box 5 and both ends of the fixing piece 7a bent downward. A pair of side pieces 7b to be formed, a pair of first claw pieces 7c that are bent from the lower end of the side piece 7b toward the opposite side piece 7b, and face each other from a substantially middle in the vertical direction of the side piece 7b. And a pair of second claw pieces 7d protruding toward the side piece 7b.

  As shown in FIG. 6, a first interval W4, which is an interval between the pair of side pieces 7b of the fixing device 7, is substantially the same as the second width W2 of the lighting fixture 6, and the distance between the pair of first claw pieces 7c is The second interval W5, which is the interval, is smaller than the second width W2, and the third interval W6, which is the interval between the first and second claw pieces 7c and 7d, is slightly longer than the height L1 of the lighting fixture 6. . Further, since the lower end face 7e of the first claw piece 7c is inclined upward toward the tip, when the lighting fixture 6 is pushed into the fixture 7 from below, the lower end face 7e serves as a guide to move the lighting fixture 6 The lighting fixture 6 can be easily fitted to the fixing tool 7 and held between the first claw piece 7c and the second claw piece 7d so as not to fall. As shown in FIG. 4, the side piece 7b is formed at a height such that the lower end does not protrude from the ceiling surface 3a toward the living room 21 when the fixture 7 is installed in the concave groove 51.

  The wood grain board 3c shown in FIG. 5 has a board width of about 80 mm to 100 mm, and the first width W1 of the slit 3b of the ceiling finishing material 31 is about 20 mm to 30 mm, and is particularly preferably about 22 mm. Further, it is preferable that the lighting fixture 6 is a long and narrow line illumination having a second width W2 of about 10 mm to 18 mm, and the third width W3 of the concave groove 51 of the lighting box 5 is formed to be about 50 mm to 60 mm. In this way, by reducing the first width W1 and the second width W2, the presence of the concave groove 51 of the lighting box 5 and the lighting fixture 6 that can be seen from the slit 3b when looking over the living room 21 can be suppressed, The living room 21 can be made a space with a clear impression.

  Next, a construction procedure of the lighting installation structure 1 will be described. First, as shown in FIG. 7, the two ridges 33 are arranged in the horizontal direction at an interval corresponding to the width of the lighting box 5, and are hung on the structural material X shown in FIG. Then, the illumination box 5 is arranged between the two ridges 33 with the concave groove 51 facing downward, and is fixed to the ridge 33 from the side surface 5b side with screws or the like. At this time, the lighting box 5 is fixed such that the lower end surface 5c of the side plate forming the side surface 5b protrudes below the lower end surface of the ridge 33 by the thickness of the ceiling base plate 32 by about the thickness of the ceiling base plate. When the screw 32 is fixed to the lower end surface of the field edge 33, the lower end surface 5c of the lighting box 5 and the lower end surface of the ceiling base material 32 can be made substantially flush as shown in FIG.

  Next, as shown in FIG. 8, the fixing piece 7a of the fixing tool 7 is fixed to the bottom face 5a of the lighting box 5 with a screw or the like in a state where the side piece 7b of the fixing tool 7 faces the side face 5b of the concave groove 51. I do. Then, as shown in FIG. 3, the fixtures 7 are sequentially fixed to the lighting box 5 along the longitudinal direction of the lighting box 5 while keeping a fixed interval, and as shown in FIG. 8, the lighting fixture 6 is fixed from below. The lighting fixture 6 is held between the first claw piece 7c and the second claw piece 7d by being pushed into and fitted into the fixture 7. As shown in FIG. 3, after connecting the lighting fixture 6 and the electric wiring 8, finally, the longitudinal direction of the slit 3 b and the longitudinal direction of the lighting box 5 are aligned, and the ceiling finishing material 31 is interposed via the ceiling base material 32. Is fixed to the edge 33 with screws or the like.

  At this time, as described above, the first width W1 of the slit 3b shown in FIG. 5 is wider than the second width W2 of the lighting fixture 6 and smaller than the third width W3 of the bottom surface 5a. As shown in the figure, the lower end surface 5c of the lighting box 5 is covered with the ceiling finishing material 31, so that even if the ceiling 3 is viewed from the living room 21, the portion other than the inner surface of the concave groove 51 of the lighting box 5 can be visually recognized. Can not. In addition, since the bottom surface 5a and the side surface 5b of the concave groove 51 are black-finished, even if the bottom surface 5a and the side surface 5b are slightly seen from between the lighting fixture 6 and the slit 3b when looking up at the ceiling 3, the concave surface is formed. The presence of the groove 51 is hardly felt. Since the lower end of the side piece 7b of the fixture 7 does not protrude toward the living 21 from the ceiling surface 3a, the lighting fixture 6 held by the fixture 7 may not be exposed from the ceiling surface 3a to the living 21 side. Instead, the living room 21 can be made a space with a clear impression. Further, since the slits 3b are formed so as to have the same longitudinal direction as the wood grain board 3c constituting the ceiling finishing material 31, even when looking up at the ceiling 3, the slits 3b are not easily conspicuous with the straight line in the longitudinal direction of the wood grain board 3c. It can be suppressed effectively. The eaves ceiling 4 shown in FIG. 2 has the same configuration as the ceiling 3 except that it is formed in an outdoor space, and the lighting installation structure 1 used around the ceiling 3 and the eaves ceiling 4 has the same configuration. Therefore, the description of the eaves ceiling 4 and the lighting installation structure 1 around the eaves ceiling 4 is omitted.

  In the lighting installation structure 1 formed in this way, the lighting box 5 and the lighting fixture 6 are not exposed from the ceiling surface, so that the design of the ceiling finishing material 31 having the wood grain is not impaired, and the living room 21 and the terrace 22 are neatly arranged. It can be a space with the impression that it was. In addition, when the terrace 22 is viewed from the living room 21, the sight is not obstructed by these lighting devices, so that the continuity of the living room 21 and the terrace 22 can be further improved, and the living room 21 continues to the terrace 22 seamlessly. You can feel like a space with depth. Even if the lighting device 6 is turned on, the lighting box 5 and the lighting device 6 are not reflected on the surface material 2e of the opening 2a as in the related art, so that these lighting devices are used not only during the day but also at night. Does not feel annoying.

  Further, as shown in FIG. 2, since the longitudinal direction of the lighting fixture 6 installed on the ceiling 3 is orthogonal to the in-plane direction of the first opening 2b, when the lighting fixture 6 is turned on at night, The elongated illumination light extending toward the one opening 2b is reflected on the surface material 2e to emphasize the depth direction of the living room 21, and can impress the living room 21 as a deeper and wider space. Since the ceiling 3 and the eaves ceiling 4 have the lighting installation structure 1 respectively, the terrace 22 can be brightly illuminated by turning on the lighting fixture 6 of the eaves ceiling 4 even at night, and the living room 21 and the living room 21 The continuity between the living room 21 and the terrace 22 can be increased without impairing the design of the terrace 22.

  It should be noted that the embodiment of the present invention is not limited to the above-described embodiment, and can be appropriately changed without departing from the scope of the concept of the present invention.

  INDUSTRIAL APPLICABILITY The lighting installation structure according to the present invention can be suitably used for a detached house having a living room having a wood-plated ceiling.
