Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an indirect lighting structure, and more particularly to an indirect lighting structure capable of uniformly illuminating a room.

[0002]

2. Description of the Related Art Heretofore, an illumination method has been adopted which is not only for directly illuminating a room but also indirectly for illuminating a room. That is, it is a lighting method in which the light emitted from a light bulb or the like for lighting is reflected once on the ceiling or the upper part of the wall surface and then illuminated in the room.
In this case, since the light source does not directly enter the human eyes, it is possible to produce soft light and shadow that is not dazzling.

Based on such a purpose, as a conventional indirect illumination structure which is formed for indirect illumination of the end portion on the wall surface side of the ceiling, the following structure is known. An example of the indirect illumination structure will be described with reference to FIGS. Here, FIG. 4 is a partial cross-sectional view of a conventional indirect lighting structure, and FIG. 5 is a plan view of a bottom plate on which a lighting fixture is arranged.

In order to provide indirect illumination, the luminaire 120

The recessed portion 105 is formed in the corner portion between the wall surface 140 and the wall surface 140 so as to open downward as follows.

That is, the recess 105 has a hanging tree 134 for fixing the gypsum board 162 for forming the ceiling surface 160, and a field edge 130 fixed to the hanging tree 134.
Gypsum board 17 for forming the upper inner surface of the recess 105
The field edge 130 for fixing 2 is formed as a basic frame member thereof, and is configured by providing the gypsum board 162 which is vertically positioned on the ceiling surface 160 and the gypsum board 172 which is horizontally positioned.

Further, in order to secure a space for mounting the lighting fixture 120 and to form a part of the ceiling surface 160,
A plurality of extending field edges 131 are horizontally extended with respect to the field edge 130 fixed to the lower end of the hanging tree 134. In addition, the extension width of the extension field edge 131 is set to a length suitable for allowing the reflected light from the lighting fixture 120 to illuminate the lower part appropriately and mounting the lighting fixture 120. That is, the extension width of the extension field edge 131 was formed according to the depth width of the lighting fixture 120.

On the other hand, as the structure of the recess 105 on the wall surface 140 side, a plywood board 146 provided on the wall panel 142 is further provided with a gypsum board 146, and a field edge 130 is provided at an appropriate position above the gypsum board 146. The gypsum board 172 is provided across the edge 130 and the field edge 130 fixed to the hanging tree 134, thereby forming the upper inner surface of the recess 105. The gypsum board 170 was also provided on the field edge 130 fixed to the hanging tree 134 in order to form the inner surface of the recess 105. Further, the gypsum board 162 was also provided on the wall surface side end portion of the extended field edge 131 extended to the field edge 130. Gypsum board 16 provided in this way
2, gypsum board 172, gypsum board 146, cloth 1 to adjust the appearance of their outer surface, respectively
64, cloth 150, and cloth 148 were stretched.

In the recess 105 formed as described above, the lighting fixture 120 is placed on the upper portion of the extended portion formed by the extended field edge 131 via the heat insulating material 124. Specifically, as shown in FIG. 5, a support base 123 having substantially the same plane shape as the heat insulating material 124 is arranged on the heat insulating material 124. A light emitting portion 121 which is long and capable of emitting light is disposed on the support base 123, and is located at both ends of the light emitting portion 121 in the longitudinal direction, and is extended upward from the support base 123 so that the light emitting portion is provided. The luminaire 20 including the supporting portion 122 for supporting is arranged.

As shown in FIG. 5, the lighting fixture 120 is fixed on the field edge 131 extending in parallel in two rows. In the lighting fixtures 120 facing each other in two rows, the light emitting section 121 in one row is the light emitting section 121 in the other row.
The support portions 122 in one row are arranged so as to correspond to the support portions 122 in the other row. It should be noted that the heat insulating material 124 has a structure that the heat generated by the lighting equipment 120 is transmitted downward and is attached to the surface of the ceiling surface 160.

[0010]

However, the conventional indirect lighting structure as described above has the following problems. That is, as shown in FIG.
When 0s are arranged in parallel in two rows, the support portions 122
Since the luminous body is not arranged in the portion of FIG. 3 and the portion between the luminaires 120 arranged in the longitudinal direction, the portion becomes dark and a shaded portion where a predetermined illuminance is not obtained is formed. For this reason, the first problem is that illumination unevenness occurs in a portion where the light emitting portions 121 are concentrated in the longitudinal direction of the container and a portion where the light emitting portions 121 are not arranged, resulting in poor appearance. There was a point.

Further, in order to form the concave portion 105 capable of accommodating the lighting fixture 120, the extended field edge 13 as described above is formed.
Not only the work of extending a plurality of 1 is necessary,
It was necessary to provide the gypsum board 162 and the gypsum board 170 as refractory materials in the above-mentioned portions of the 0 and the extended field edge 131. The construction work of the gypsum board 162 and the gypsum board 170 cannot be omitted from the viewpoint of ensuring fire resistance performance.

Since such a recess 105 is formed as a relatively small space and is formed at a high position near the ceiling, it is difficult to carry out the work, and it is difficult to endure. Further, the work of providing the cloth 150 as the finishing material after the formation of the concave portion 105 is also a work that cannot be endured as in the above.

Further, the work of placing the lighting fixture 120 and the heat insulating material 124 on the upper portion of the extended field edge 131 is similarly troublesome. As described above, the conventional indirect lighting structure has a second problem in that the work is difficult to perform and cannot be bothered. Therefore, the invention according to claim 1 is made in view of the first problem of the above-described conventional technique,

Next, a storage body 10 that matches the size of the recess 5 and can be stored in the recess 5 will be described with reference to FIG. The storage body 10 has a generally U-shaped vertical cross section, and has an overall shape such that its opening side faces the wall surface 40 side. That is, the storage body 10 is formed so that the lighting fixture 20 can be placed thereon, and the ceiling surface 60 located on the side opposite to the wall surface 40 of the recess 5 is extended to the wall surface 40 side so that a gap is formed between the ceiling surface 60 and the wall surface 40. The formed bottom plate 12, a standing plate 14 in which the end of the bottom plate 12 on the side opposite to the wall surface 40 is bent upward along the inner surface of the recess 5, and the upper end of the standing plate 14 extends along the inner surface of the recess 5. Top plate 1 bent toward the wall 40 side
And 6 are formed. The width of the top plate 16 is
It has the same width as the plywood 70.

In addition, the gap between the end portion of the bottom plate 12 on the wall surface 40 side, that is, the ceiling surface 60 is separated from the wall surface 40 is that the light from the lighting fixture 20 is on the top plate 16 or the upper portion of the wall surface 40. The light is reflected so that the lower part can be appropriately illuminated. Further, an end portion of the bottom plate 12 on the wall surface 40 side is bent slightly upward to form a standing portion 13. The standing portion 13 has a function as a catch for preventing the lighting fixture 20 from falling, and is provided to wind the end portion of the cloth 64 on the wall surface 40 side upward so as to adjust the appearance from below. Is.

The container 10 thus formed uses a metal plate which is a non-combustible member in order to ensure excellent fire resistance in the entire container structure. The inner surfaces of the top plate 16 and the standing plate 14 are appropriately coated so as to adjust their appearance. On the upper part of the bottom plate 12, the lighting fixture 20 is placed via a heat insulating material 24. This heat insulating material 24 allows the heat generated by the luminaire 20 to be transmitted to the lower side of the ceiling surface 6
The cloth 64 attached to the surface of 0 is provided so as not to fade.

On the heat insulating material 24, as shown in FIGS. 1 and 2, the support base 2 having the same planar shape as the heat insulating material 24 is provided.
3 is fixed. A long light-emitting portion 21 capable of emitting light is disposed on the support base, and is positioned at both ends of the light-emitting portion 21 in the longitudinal direction, and is extended upward from the support base 23 so that the light-emitting portion 21 is provided. A lighting fixture 20 including a supporting portion 22 that supports the lighting fixture 20 is fixed.

In this embodiment, as the lighting fixture 20, two rod-shaped fluorescent lamps are arranged in parallel as shown in FIG. 1, but the ends of the fluorescent lamps are not concentrated in the same place. It is located in. That is, except for the support portions 22 located at both ends of the housing 10 in the longitudinal direction, the support portions 22 of the lighting fixtures 20 in one row are not included in the lighting fixtures 20 in the other row.
Is arranged so as to face the substantially central portion of the light emitting portion 21 in the longitudinal direction. Although not shown, the lighting fixture 20
Predetermined wiring is applied to the.

The storage body 10 formed as described above is inserted into the inside of the recess 5, and the top plate 16 of the storage body 10 is fixed to the plywood 70 by fixing screws 18 or the like.
In this case, the bottom plate 12 of the storage body 10 is flush with the lower surface of the plaster board 62. After the container 10 is fixed in the recess 5, a cloth 64 is stretched over the lower surfaces of the gypsum board 62 and the bottom plate 12 to ensure the appearance.
That is, since the bottom plate 12 of the storage body 10 is flush with the lower surface of the gypsum board 62, when the cloth 64 is stretched on this surface and the ceiling surface 60 is viewed from below the ceiling surface 60,
It seems that the ceiling surface 60 is integrally formed up to the end of the bottom plate 12 on the wall surface 40 side.

A cloth 48 is also stretched on the surface of the gypsum board 46 to ensure the appearance of the wall surface 40. Next, the operation of this embodiment will be described. First, the wall end of the plaster board 62 is fixed by providing the field edge 30 and the hanging tree 34 at the end of the plaster board 62 for forming the ceiling surface 60 on the wall surface 40 side.

Next, on the wall surface 40 side of the hanging tree 34,
A field edge 3 for fixing the plywood 70 so that the lower surfaces of both sides are in the same horizontal position in the middle of the longitudinal direction and the surface of the wall surface 40.
0,30 are formed. The plywood 70 is fixed to the lower surfaces of the field edges 30, 30 with screws or the like. This makes it possible to form the recess 5 that opens downward at the entry corner formed by the ceiling surface 60 and the wall surface 40 in the room. The wall panel 42 also has a plywood 44 and a gypsum board 4
6 is provided.

After the recess 5 is formed, the lighting fixture 20 is placed on the bottom plate 12 of the housing 10. Lighting fixture 20
Are the support portions 22 located at both ends in the longitudinal direction of the container 10.
With the exception of the above, the support portions 22 of the lighting fixtures 20 in one row are arranged on the bottom plate 12 so as to face the light emitting portions 21 of the lighting fixtures 20 in the other row. After the lighting fixture 20 is placed in the housing 10, the housing 10 is inserted and fixed in the recess 5.

In the above case, the supporting portions 22 are always arranged so as to be adjacent to the light emitting portions 21 in the other row, except for the supporting portions 22 located at both ends in the longitudinal direction of the container 10. The support portions 22 that do not emit light are not adjacent to each other. Therefore, with respect to the longitudinal direction of the storage body 10,
A light emitting section 21 capable of emitting light is always arranged in one of the columns. Thereby, the illumination is continuously performed in the longitudinal direction of the container 10 without interruption, and it is possible to prevent uneven illumination.

Further, since the bottom plate 12 is flush with the lower surface of the gypsum board 62, when the cloth 64 is stretched on this surface and the ceiling surface 60 is viewed from below the ceiling surface 60, the ceiling surface 60 is the bottom plate. It seems that the end of the wall surface 12 of 12 is integrally formed. That is, the appearance of the ceiling surface 60 can be secured. Further, since the bottom plate 12 is formed, it is not necessary to construct the field fixture as a part on which the lighting fixture 20 is mounted by assembling the field edge.

Further, the bottom plate 12, the standing plate 14 and the top plate 1
Since 6 is formed of a metal plate, excellent fire resistance can be obtained without constructing a gypsum board. That is, the construction work of the gypsum board in the part concerned can be omitted. The light from the lighting fixture 20 as a light source can be reflected by the top plate 16 and the wall surface 40 to illuminate the lower part of the recess 5. In this case, the lighting device 20 as the light source is the bottom plate 1
Since it is placed on top of 2, it is not visible from below.

Next, the effect of this embodiment will be described. According to the present embodiment, the indirect lighting structure can be provided only by inserting and fixing the storage body 10 into the recess 5 formed as described above. In addition, by providing the bottom plate 12 in the storage body 10, not only is it unnecessary to construct the field fixture as a portion for mounting the lighting fixture 20, but the bottom plate 12 is flush with the lower surface of the gypsum board 62. Therefore, after the cross 64 is stretched on such a surface, the ceiling surface 6
When 0 is seen, it seems that the ceiling surface 60 is integrally formed up to the end portion on the wall surface 40 side of the bottom plate 12, and there is an effect that the appearance of the ceiling surface 60 can be secured.

Further, the bottom plate 12, the standing plate 14 and the top plate 1
Since 6 is formed of a metal plate, excellent fire resistance can be obtained without constructing a gypsum board. That is, there is an effect that the construction work of the gypsum board in the relevant portion can be omitted. In addition, as the lighting fixture 20, two rod-shaped fluorescent lamps arranged in parallel are used, and the support portions 22 that do not emit light of the fluorescent lamps are arranged so as not to concentrate on the same place, and the housing 10 Since the light emitting portions 21 of the lighting fixtures 20 are always arranged in one of the rows with respect to the longitudinal direction, a so-called shaded portion does not occur in the longitudinal direction and is uniform. The illuminance can be obtained.

Next, variations of this embodiment will be described. In this embodiment, two lighting fixtures 20 are arranged in two rows in the longitudinal direction of the storage body 10, and a total of four lighting fixtures 20 are used. There is no limitation. It is possible to deal with the situation by increasing or decreasing the number of the lighting fixtures 20 according to the size of the room. For example, when the indoor space is small, it is possible to arrange two units in the same column in parallel and use a total of two units. In addition, when the room is large, it is possible to deal with the situation by increasing the number of the lighting fixtures 20 in the longitudinal direction.

Further, in FIG. 2, the supporting portion 22 of one row is set to be located substantially at the center of the light emitting portion 21 of the other row, but the present invention is not particularly limited to this. It is also possible to arrange so that the supporting portions 22 of the row of (1) face the supporting portions 22 of the other row, and face the arbitrary positions of the light emitting portions 21 of the other row. As a result, the lighting fixture 20 can be arranged from end to end without being constrained by the dimension of the lighting fixture 20 in the longitudinal direction even in a room having an arbitrary size, and uneven illumination is not generated. An indirect lighting structure can be obtained.

Further, in this embodiment, the lighting fixtures 20 are arranged in two rows and used, but the present invention is not limited to this, and the support portions 22 of one row of the lighting fixtures 20 may be arranged in other rows. The lighting fixtures 20 can be arbitrarily arranged in three or more rows as long as the lighting fixtures 20 are arranged so as to face the light emitting portions 21. This makes it possible to obtain an indirect illumination structure with arbitrary brightness.

Further, a rotating plate (not shown) for mounting the lighting fixture 20 is placed on the upper portion of the bottom plate 12, and the wall 40 side end of the rotating plate and the wall 40 side end of the bottom plate 12 are placed. It is also possible to connect by a connecting member such as a hinge and to form the rotating plate so as to be rotatable with respect to the bottom plate 12 about the connecting member. If formed in this way, even when performing construction work and maintenance work such as wiring of the lighting fixture 20,
If the rotating plate is rotated so as to be positioned below the bottom plate 12, the work can be easily performed.

Next, a second embodiment of the present invention will be described. FIG. 3 is a plan view of a lighting fixture having an indirect lighting structure according to a second embodiment of the present invention. In the present embodiment, in contrast to the first embodiment, the lighting fixtures 20 are independently arranged in each row in the longitudinal direction of the storage body 10, whereas in FIG. As shown in FIG. 4, the lighting fixture 20 is arranged in a unit. The other structure is the same as that of the first embodiment.
The same part number as that of the embodiment of FIG.

As shown in FIG. 3, the unitization of the indirect lighting structure according to the present embodiment is performed by arranging the left end illumination unit 25 located at the left end in the longitudinal direction of the bottom plate 12 and the right end located at the right end in the longitudinal direction of the bottom plate 12. It is formed by the lighting unit 27 and the intermediate lighting unit 26 located between the left end lighting unit 25 and the right end lighting unit 27. More specifically, in the left-end lighting unit 25, one lighting fixture 20 is arranged in only one row, and the planar shape is L.
It is formed in a letter shape. The right end lighting unit 27 has one lighting fixture 20 arranged only in the other row, and has an L-shaped planar shape. Intermediate lighting unit 2
7, two lighting fixtures 20 are arranged in two rows, and the support portion 22 of the lighting fixture 20 in one row is the lighting fixture 20 in the other row.
Are arranged so as to face the light emitting portion 21 of the.

As described above, in the indirect lighting structure according to this embodiment, the lighting fixture 20 is composed of the lighting units 25 to 27. Therefore, as compared with the first embodiment, the mounting work of the lighting fixture 20 can be performed for each lighting unit, so that the on-site work can be facilitated. Further, even a room having a larger size can be easily dealt with by increasing the number of the intermediate lighting units 26. Further, even for a room having a smaller size, the intermediate lighting unit 26 can be omitted and the left end lighting unit 25 and the right end lighting unit 27 can be used. Further, the support portion 22 of the lighting fixture 20 in one row
Does not face the support portion 22 of the other row, and the light emitting portion 2 of the other row
By arranging so as to face No. 1, an indirect lighting structure capable of coping with a room of arbitrary size without causing uneven lighting by appropriately shifting the positions of the lighting units in the longitudinal direction. Can be provided.

Further, in this embodiment, the lighting fixture 2
Although only the arrangement of 0 is unitized, the storage body 10 also corresponds to the arrangement of the lighting fixture 20 in the longitudinal direction in advance, and the storage body 1
The housing unit (not shown) may be formed for each of the lighting units 25 to 27 by dividing the unit in the longitudinal direction of 0. That is, although not shown, a left end storage unit unit, an intermediate storage unit unit, and a right end storage unit unit are formed corresponding to the left end illumination unit 25, the intermediate illumination unit 26, and the right end illumination unit 27, respectively.

With this, it is possible to cope with rooms of different sizes by appropriately combining the appropriate numbers of the respective storage unit units. Therefore, it is only necessary to form three types of housing units in the factory, and it is possible to further promote factory production of the components of the indirect lighting structure and further reduce the manufacturing cost.
