A second opening 2c and a third opening 2d that extend in the direction orthogonal to the first opening 2b from both ends. Further, as shown in FIG. 2, the opening 2a is a large opening extending from the floor F1 of the living room 21 to the ceiling 3, and the living room 21 is provided with a transparent face material 2e such as transparent glass. Therefore, the terrace 22 can be widely viewed. Then, the height of the ceiling 3 of the living room 21 and the height of the eaves ceiling 4 are formed to be 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 to be substantially the same. It is possible to obtain a feeling as if the living room 21 is a space with a depth that continuously extends to the terrace 22.

Next, the lighting installation structure 1 around the ceiling 3 will be described with reference to FIGS. 3 to 8. As shown in FIG. 4, in the lighting installation structure 1, the lower end surface forms the ceiling surface 3a of the ceiling 3, and a plate-shaped ceiling finishing material 31 having a slit 3b penetrating in the plate thickness direction, and above the slit 3b. The lighting box 5 has a concave groove shape in cross section and is arranged so that the opening portion of the concave groove 51 is located in the concave box 51, and the lighting fixture 6 fixed in the concave groove 51 of the lighting box 5.

As shown in FIG. 3, a ceiling pocket S is formed between the ceiling 3 and the structural material X such as the floor or roof of the upper floor, and the ceiling 3 is hung on the structural material X by a hanging bracket. .. 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 ceiling pocket S side of the ceiling finishing material 31, a ceiling finishing material 31, and a ceiling base surface. And an elongated field edge 33 that supports the material 32.

As shown in FIG. 5, the ceiling finishing material 31 is formed by fitting a plurality of elongated wood grain boards 3c having wood grain (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 surface. The dowel groove 3e of a different wood grain board 3c can be fitted into the dowel groove 3d. With this, a so-called siding plate-attached face material can be obtained. The ceiling finishing material 31 thus formed is formed with the slit 3b penetrating in the plate thickness direction along the longitudinal direction of the wood grain board 3c, and the first width W1 which is the width of the slit 3b is a lighting fixture. The width of the slit 3b is wider than the second width W2 which is the width of the slit 6, and the length of the slit 3b is formed to be substantially the same as the length of the lighting fixture 6, as shown in FIG.

As shown in FIG. 4 and FIG. 5, the lighting box 5 is an elongated wooden member that supports the lighting fixture 6 and has a concave groove shape in a sectional view. The concave groove 51 faces downward and the concave groove is formed above the slit 3b. It is installed so that the opening portion of 51 is located. In the lighting box 5, the bottom surface 5a and the side surface 5b, which are the inner side surfaces of the recessed groove 51, are black-finished with paint or sheet material, and when the ceiling 3 is looked up from the living room 21, the presence is not very noticeable. Almost never. Further, the third width W3, which is the width of the bottom surface 5a of the illumination box 5 shown in FIG. 5, is wider than the first width W1 and the second width W2, and as shown in FIG. The length of the slit 3b and the length of the lighting fixture 6 are substantially the same.

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 pocket S is connected to one end in the longitudinal direction. It can be turned on or off by turning on and off a hand switch (not shown) installed on the wall surface of the living room 21. Further, the lighting fixture 6 is installed in the concave groove 51 of the illumination box 5 by the substantially concave groove-shaped fixture 7 shown in FIGS. 4 and 6. The fixture 7 is a member made of hard resin or metal and having a slight elasticity. The fixture 7a is fixed to the bottom surface 5a of the illumination box 5, and both ends of the fixture 7a are bent downward. A pair of side pieces 7b formed, a pair of first claw pieces 7c bent from the lower end of the side pieces 7b toward the opposite side pieces 7b, and the side pieces 7b face each other from substantially the middle in the vertical direction. It is formed by a pair of second claw pieces 7d protruding toward the side piece 7b.

As shown in FIG. 6, the first interval W4, which is the interval between the pair of side pieces 7b of the fixture 7, is approximately the same as the second width W2 of the lighting fixture 6, and the first claw pieces 7c of the pair are separated from each other. The second interval W5, which is the interval, is narrower than the second width W2, and the third interval W6, which is the interval between the first claw piece 7c and the second claw piece 7d, is slightly longer than the height L1 of the lighting fixture 6. .. Further, since the lower end surface 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 for the lighting fixture 6. It can be easily fitted to the fixture 7, and the lighting fixture 6 can be held between the first claw piece 7c and the second claw piece 7d so as not to drop. Further, as shown in FIG. 4, the side piece 7b is formed at a height such that when the fixture 7 is installed in the recessed groove 51, the lower end does not project beyond the ceiling surface 3a toward the living room 21.

The board width of the wood grain board 3c shown in FIG. 5 is about 80 mm to 100 mm, and the first width W1 of the slit 3b of the ceiling finishing material 31 is formed at about 20 mm to 30 mm, preferably about 22 mm. The lighting fixture 6 is preferably 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 of about 50 mm to 60 mm. In this way, by narrowing the first width W1 and the second width W2, it is possible to suppress the presence of the recessed groove 51 of the lighting box 5 and the lighting fixture 6 that are seen through the slit 3b when looking over the living room 21, The living room 21 can be a space with a clean impression.

Next, a procedure for constructing the lighting installation structure 1 will be described. First, as shown in FIG. 7, the two field edges 33 are arranged in the horizontal direction with an interval corresponding to the width of the illumination box 5, and are suspended from the structural member X shown in FIG. Then, the illumination box 5 is arranged between the two field edges 33 with the concave groove 51 facing downward, and is fixed to the field edge 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 projects downward from the lower end surface of the field edge 33 by about the plate thickness of the ceiling base material 32 and the ceiling base material. When 32 is fixed to the lower end surface of the field edge 33 with screws, 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 with each other, as shown in FIG.

Next, as shown in FIG. 8, with the side piece 7b of the fixture 7 facing the side surface 5b of the recessed groove 51, the fixture piece 7a of the fixture 7 is fixed to the bottom surface 5a of the illumination box 5 with screws or the like. To do. Then, as shown in FIG. 3, fixing fixtures 7 are sequentially fixed to the illumination box 5 along the longitudinal direction of the illumination box 5 while leaving 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 the tool 7 and fitted therein. 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 provided via the ceiling base material 32. Is fixed to the field 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 narrower than the third width W3 of the bottom surface 5a. As shown, the lower end surface 5c of the lighting box 5 is covered with the ceiling finishing material 31, and even when the ceiling 3 is looked up from the living room 21, the portion other than the inner side surface of the concave groove 51 of the lighting box 5 can be visually recognized. I can't. Further, since the bottom surface 5a and the side surface 5b of the concave groove 51 have a black finish, even when the bottom surface 5a and the side surface 5b are slightly visible from between the lighting fixture 6 and the slit 3b when looking up at the ceiling 3, the concave portion The existence of the groove 51 is hardly felt. Since the lower end of the side piece 7b of the fixture 7 does not project to the living room 21 side from the ceiling surface 3a, the lighting fixture 6 held by the fixture 7 is not exposed from the ceiling surface 3a to the living room 21 side. Instead, the living room 21 can be used as a space with a clean impression. Furthermore, since the slits 3b are formed in alignment with the wood grain board 3c that constitutes the ceiling finishing material 31 in the longitudinal direction, the slits 3b are not conspicuous even when looking up at the ceiling 3 because they are intimate with the straight lines in the longitudinal direction of the wood grain board 3c, and their presence is enhanced. It can be effectively suppressed. 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 will be omitted.

In the lighting installation structure 1 formed in this way, since the lighting box 5 and the lighting fixture 6 are not exposed from the ceiling surface, the design of the ceiling finishing material 31 having wood grain is not impaired, and the living room 21 and the terrace 22 are clean. It can be a space with the impression. In addition, since the visibility is not obstructed by these lighting devices when the terrace 21 is viewed from the living room 21, the continuity of the living room 21 and the terrace 22 can be further enhanced, and the living room 21 continues to the terrace 22 seamlessly. You can feel like a deep space. Even when the lighting fixture 6 is turned on, the lighting box 5 and the lighting fixture 6 do not appear on the face material 2e of the opening 2a as in the conventional case, so that these lighting devices are used not only during the daytime but also at night. Don't feel annoyed.

Further, as shown in FIG. 2, since the longitudinal direction of the lighting fixture 6 installed on the ceiling 3 and the in-plane direction of the first opening 2b are orthogonal to each other, when the lighting fixture 6 is turned on at night, The elongated illumination light extending toward the first opening 2b is reflected on the surface material 2e to emphasize the depth direction of the living room 21, and the living room 21 can be further impressed as a wide space with a large depth. Since the ceiling 3 and the eaves ceiling 4 each have the lighting installation structure 1, it is possible to illuminate the terrace 22 brightly by turning on the lighting fixtures 6 of the eaves ceiling 4 even at night, and the living room 21 and The continuity between the living room 21 and the terrace 22 can be enhanced without impairing the design of the terrace 22.

The embodiment of the present invention is not limited to the above-described embodiment, and can be appropriately modified without departing from the scope of the idea 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 ceiling made of wood.
