図１ａの間接照明装置１０は、連結具２５を介して壁面１に取り付けられるものであり、間接照明装置１０から照射された光が壁面で反射し、その反射光により間接的に照明するものである。符号１ａは、間接照明装置１０から照射された光が壁面に沿って現れている様子を示す。特に外壁へ間接照明を施すのに好ましいものであり、壁面に取り付けられる化粧枠や装飾材としても用いることもできる。
間接照明装置１０は、図１ｂに示すように、壁面１に取り付けられる長尺基材１１と、その長尺基材１１の収容部に収容される照明１２とを備えている。 The indirect lighting device 10 of FIG. 1a is attached to the wall surface 1 via a connector 25, and the light emitted from the indirect lighting device 10 is reflected by the wall surface and indirectly illuminated by the reflected light. is there. Reference numeral 1a indicates that the light emitted from the indirect lighting device 10 appears along the wall surface. In particular, it is preferable for indirect lighting on the outer wall, and it can also be used as a decorative frame or a decorative material attached to the wall surface.
As shown in FIG. 1b, the indirect lighting device 10 includes a long base material 11 attached to the wall surface 1 and a lighting 12 housed in a housing portion of the long base material 11.

長尺基材１１は、図２ａに示すように、長手方向に垂直な断面形状が、Ｃ状の周壁１６と、その周壁の内部空間２０を仕切る仕切壁１７と、Ｃ状の周壁１６に設けられた内部空間２０と外部とを連通する穴１８とを有している。
周壁１６は、天板１６ａと、その両端から天板１６ａに対して垂直に同じ方向に延びる２つの側板１６ｂ１、１６ｂ２とを備えて、周壁１６は両側板１６ｂ１、１６ｂ２の先端同士を繋いだ面１６ｃが開口している。一方の側板１６ｂ１（図２ａの左側）に穴１８が形成されている。
このような長尺基材１１は、間接照明装置１０を壁面１に取り付けたとき、周壁１６の開口した面１６ｃが壁面１と対向する。つまり、この周壁１６の開口は、壁面１に固定された連結具２５を受け入れ、壁面１によって閉じられる（図１ｂ参照）。また、長尺基材１１を壁面１に取り付けたとき、天板１６ａは壁面１と平行となる。天板１６ａの表面には、用途に応じてデザイン等が施されている。また長尺基材１１の両端部は、図２ｂのエンドキャップ１１ａによって閉じられている。 As shown in FIG. 2a, the long base material 11 is provided on the C-shaped peripheral wall 16, the partition wall 17 that partitions the internal space 20 of the peripheral wall, and the C-shaped peripheral wall 16 having a cross-sectional shape perpendicular to the longitudinal direction. It has a hole 18 that communicates the internal space 20 and the outside.
The peripheral wall 16 includes a top plate 16a and two side plates 16b1 and 16b2 extending in the same direction perpendicularly to the top plate 16a from both ends thereof, and the peripheral wall 16 is a surface connecting the tips of the side plates 16b1 and 16b2. 16c is open. A hole 18 is formed in one side plate 16b1 (left side in FIG. 2a).
In such a long base material 11, when the indirect lighting device 10 is attached to the wall surface 1, the open surface 16c of the peripheral wall 16 faces the wall surface 1. That is, the opening of the peripheral wall 16 receives the connector 25 fixed to the wall surface 1 and is closed by the wall surface 1 (see FIG. 1b). Further, when the long base material 11 is attached to the wall surface 1, the top plate 16a is parallel to the wall surface 1. The surface of the top plate 16a is designed according to the intended use. Both ends of the long base material 11 are closed by the end caps 11a of FIG. 2b.

仕切壁１７は、天板１６ａから略垂直に延びる縦壁１７ａ１、１７ａ２と、それぞれ側板１６ｂ１、１６ｂ２から略垂直に延びる横壁１７ｂ１、１７ｂ２とを有する。縦壁１７ａ１、１７ａ２、および、横壁１７ｂ１、１７ｂ２は、天板１６ａの幅方向（図２ａの左右方向）の中心線Ｃ１を中心として左右対称に設けられている。そして、縦壁１７ａ１と横壁１７ｂ１および縦壁１７ａ２と横壁１７ｂ２とが交差している。
その他の仕切壁１７としては、縦壁１７ａ１と縦壁１７ａ２とが連続するように、その下端からＹ字状にＹ字壁１７ｃが設けられている。またそれぞれ側板１６ｂ１、１６ｂ２の下端から横壁１７ｂ１、１７ｂ２に向かって斜めに延びる傾斜壁１７ｄ１、１７ｄ２が設けられている。 The partition wall 17 has vertical walls 17a1 and 17a2 extending substantially vertically from the top plate 16a, and horizontal walls 17b1 and 17b2 extending substantially vertically from the side plates 16b1 and 16b2, respectively. The vertical walls 17a1 and 17a2 and the horizontal walls 17b1 and 17b2 are provided symmetrically with respect to the center line C1 in the width direction (horizontal direction in FIG. 2a) of the top plate 16a. Then, the vertical wall 17a1 and the horizontal wall 17b1 and the vertical wall 17a2 and the horizontal wall 17b2 intersect.
As the other partition wall 17, a Y-shaped wall 17c is provided in a Y-shape from the lower end thereof so that the vertical wall 17a1 and the vertical wall 17a2 are continuous. Further, inclined walls 17d1 and 17d2 extending diagonally from the lower ends of the side plates 16b1 and 16b2 toward the side walls 17b1 and 17b2 are provided, respectively.

長尺基材１１は、仕切壁１７によって、内部空間が７つの独立した空間（２０ａ〜２０ｇ）に仕切られている。その独立した空間の一つであり、周壁１６（天板１６ａの一部と側板１６ｂ１の一部）と、仕切壁１７（縦壁１７ａ１と、横壁１７ｂ１）に囲まれた空間２０ａは、照明１２を収容する収容部となっている。この空間（収容部）２０ａは、穴１８によって外部と連通している。また空間２０ｆ、２０ｇは、周壁１６の開口した面１６ｃから連結具２５を受け入れる。 The internal space of the long base material 11 is divided into seven independent spaces (20a to 20g) by a partition wall 17. One of the independent spaces, the space 20a surrounded by the peripheral wall 16 (a part of the top plate 16a and a part of the side plate 16b1) and the partition wall 17 (the vertical wall 17a1 and the horizontal wall 17b1) is illuminated by the lighting 12. It is a containment unit that houses. This space (accommodation portion) 20a is communicated with the outside by a hole 18. Further, the spaces 20f and 20g receive the connecting tool 25 from the open surface 16c of the peripheral wall 16.

このように天板１６ａから延びる縦壁１７ａ１、１７ａ２と、側板１６ｂ１、１６ｂ２から延びる横壁１７ｂ１、１７ｂ２とが交わっており、天板１６ａと側板１６ｂ１、１６ｂ２とが仕切壁１７によって連続しているため、左側板１６ｂ１に穴１８が設けられても天板１６ａと左側板１６ｂ１とを一体に保つことができる。また、周壁１６の開口した面１６ｃに対して独立した空間２０ａを確保することができ、照明１２を独立して収容することができる。さらに仕切壁１７は、天板１６ａの幅方向（図２ａの左右方向）の中心線Ｃ１を中心として左右対称に設けられているため、強度が高く、外力が加わっても壊れにくい。 Since the vertical walls 17a1 and 17a2 extending from the top plate 16a and the horizontal walls 17b1 and 17b2 extending from the side plates 16b1 and 16b2 intersect in this way, the top plate 16a and the side plates 16b1 and 16b2 are continuous by the partition wall 17. Even if the left side plate 16b1 is provided with the hole 18, the top plate 16a and the left side plate 16b1 can be kept integrally. Further, an independent space 20a can be secured with respect to the open surface 16c of the peripheral wall 16, and the illumination 12 can be accommodated independently. Further, since the partition wall 17 is provided symmetrically with respect to the center line C1 in the width direction (horizontal direction in FIG. 2a) of the top plate 16a, the partition wall 17 has high strength and is not easily broken even when an external force is applied.

穴１８は、周壁１６の左側板１６ｂ１の天板１６ａ側に形成されており、外部と空間２０ａとを連通している。長尺基材１１において、図２ｂに示すように、長手方向に延びる１本の長い穴となる。このように穴１８は、左側板１６ｂ１に形成されているため、長尺基材１１を壁面１に取り付けたとき、穴１８、つまり、収容部の開口は壁面と平行に開口することになる。そのため、収容部内に収容された照明１２は、壁面１と対向した位置から見えない。なお、穴１８に、図２ａの想像線で示すように、光透過性のカバー１８ａを設けてもよい。 The hole 18 is formed on the top plate 16a side of the left side plate 16b1 of the peripheral wall 16 and communicates the outside with the space 20a. In the long base material 11, as shown in FIG. 2b, it is one long hole extending in the longitudinal direction. Since the hole 18 is formed in the left side plate 16b1 in this way, when the long base material 11 is attached to the wall surface 1, the hole 18, that is, the opening of the accommodating portion is opened parallel to the wall surface. Therefore, the lighting 12 housed in the housing unit cannot be seen from the position facing the wall surface 1. The hole 18 may be provided with a light-transmitting cover 18a as shown by the imaginary line in FIG. 2a.

このような長尺基材１１は、セメント系押出成形体を加工して成形する。
ここで「セメント系押出成形体」とは、セメント系材料を押出成形し、硬化させたものである。
セメント系材料とは、水硬性の無機物を含むセメント系組成物を硬化させた材料である。水硬性の無機物としては、各種ポルトランドセメント、高炉セメント、フライアッシュセメント、シリカセメントなどを用いることができる。また、軽量化のために軽量化骨材等を含んでいてもよく、補強等のためにパルプ、水溶性セルロース、鉱物繊維等を含んでいてもよく、着色のために顔料を含んでいてもよい。各種のセメント系材料のなかでも、耐火性に優れ、比重が軽いことから、珪酸カルシウムを主成分とする珪酸カルシウム系材料を用いることが好ましい。また、強度に優れることから、パルプで補強された珪酸カルシウム系材料を用いることがさらに好ましい。
このようなセメント系材料は、押出成形によって、長手方向（押出方向）に断面形状がほぼ同一な成形体を容易に製造することができる。また、比重０．７〜１．５、特に０．７〜１．３程度の押出成形体であれば、軽量性による施工性の向上の効果も生じる。さらに、耐熱性を有しているため、発熱する照明を収容しても変形するおそれがなく、耐久性に優れている。硬化後のセメント系押出成形体は、ビス、ネジ、釘等の固着具により固定可能である。 Such a long base material 11 is formed by processing a cement-based extruded body.
Here, the "cement-based extrusion molded product" is a product obtained by extrusion-molding and hardening a cement-based material.
The cement-based material is a material obtained by hardening a cement-based composition containing a hydraulic inorganic substance. As the hydraulic inorganic substance, various Portland cement, blast furnace cement, fly ash cement, silica cement and the like can be used. Further, a lightweight aggregate or the like may be contained for weight reduction, pulp, water-soluble cellulose, mineral fibers or the like may be contained for reinforcement or the like, or a pigment may be contained for coloring. Good. Among various cement-based materials, it is preferable to use a calcium silicate-based material containing calcium silicate as a main component because it has excellent fire resistance and a light specific gravity. Further, it is more preferable to use a calcium silicate-based material reinforced with pulp because of its excellent strength.
Such a cement-based material can be easily manufactured by extrusion molding so as to have substantially the same cross-sectional shape in the longitudinal direction (extrusion direction). Further, in the case of an extruded body having a specific gravity of 0.7 to 1.5, particularly 0.7 to 1.3, the effect of improving workability due to light weight also occurs. Further, since it has heat resistance, it is not likely to be deformed even if it accommodates heat-generating lighting, and has excellent durability. The hardened cement-based extruded body can be fixed with a fixing tool such as a screw, a screw, or a nail.

このような長尺基材１１の製造方法は、周壁１６と、仕切壁１７とを備えたセメント系押出成形体を成形し、その後、周壁１６の一部を切削して穴１８を形成して成形する。なお、周壁１６と仕切壁１７とを備えたセメント形押出成形体は、周壁１６の開口した面１６ｃを下にしてスペーサを入れて形状を保たせながら押出して硬化させる。
セメント系押出成形体に切削加工を行うのは、押出成形体の軸方向に垂直な断面形状であって異なる２つの方向に開口している形状を、押出によって形成する場合、図２ｃに示すように、穴１８の上側の天板１６ａが下方に垂れるおそれがあるためである。つまり、２つの方向に開口している形状を押出成形するには、それぞれの開口にスペーサを挿入して形状を保持させる必要があるが、穴１８にスペーサを保持させることが困難となるためである。このように、一度、周壁１６および仕切壁１７を有するセメント系押出成形体を成形して硬化し、その後、硬化したセメント押出成形体に切削加工して穴１８を形成することにより、精度の高く、かつ、効率良く生産することができる。 In such a method of manufacturing the long base material 11, a cement-based extruded body having a peripheral wall 16 and a partition wall 17 is formed, and then a part of the peripheral wall 16 is cut to form a hole 18. Mold. The cement-type extruded body provided with the peripheral wall 16 and the partition wall 17 is extruded and cured while maintaining its shape by inserting a spacer with the open surface 16c of the peripheral wall 16 facing down.
When the cement-based extruded body is cut by extrusion to form a cross-sectional shape perpendicular to the axial direction of the extruded body and having openings in two different directions, as shown in FIG. 2c. This is because the top plate 16a on the upper side of the hole 18 may hang down. That is, in order to extrude a shape having openings in two directions, it is necessary to insert a spacer into each opening to hold the shape, but it is difficult to hold the spacer in the hole 18. is there. In this way, the cement-based extruded body having the peripheral wall 16 and the partition wall 17 is once molded and hardened, and then the hardened cement extruded body is cut to form holes 18 with high accuracy. Moreover, it can be produced efficiently.

照明１２は、縦長の空間（収容部）２０ａに収容される縦長のものである（図１ｂ参照）。詳しくは、図３ａに示すように、縦長の基板１２ａと、基板の長手方向に均等に設けられた複数のＬＥＤ１２ｂとを備えており、基板１２ａの端部に照明１２に電源を供給する配線１２ｃが設けられている。なお、ＬＥＤ以外に、蛍光灯、電球等の電力によって発光するものを用いてもよい。
照明１２は、収容部（空間２０ａ）に設けられる冶具１５に保持させている（図１ｂ参照）。冶具１５の大きさや形状を選択することにより、収容部内における照明１２の位置を調整することができる。照明１２は、冶具１５によって壁面に沿う方向に固定され、照明１２から照射される光は、図１に示すように壁面に沿って現れる。なお、図３ｂ、ｃに示すように、冶具１５の表面を傾けることにより、照明１２が壁面１に向く、つまり、光が壁面の所定の領域１ｂに現れるように調整することもできる。冶具１５は、例えば、ねじ等の固定具２６によって仕切壁の縦壁１７ａ１に固定される。
照明１２は、冶具１５と接着剤等で固定する。これにより冶具１５を取り外すことにより、照明１２の取替えができる。その場合、照明１２および冶具１５を穴１８または長尺基材１１の両端から出し入れする。しかし、例えば、互いに係合できる係止爪を照明１２の裏面および冶具の表面に設ける等、照明１２と冶具１５とを取り外し可能な構造とし、照明１２のみを出し入れするようにしてもよい。 The lighting 12 is a vertically long one housed in a vertically long space (accommodation portion) 20a (see FIG. 1b). Specifically, as shown in FIG. 3a, a vertically long substrate 12a and a plurality of LEDs 12b evenly provided in the longitudinal direction of the substrate are provided, and a wiring 12c that supplies power to the lighting 12 is provided at the end of the substrate 12a. Is provided. In addition to the LED, a fluorescent lamp, a light bulb, or the like that emits light by electric power may be used.
The lighting 12 is held by a jig 15 provided in the accommodating portion (space 20a) (see FIG. 1b). By selecting the size and shape of the jig 15, the position of the illumination 12 in the accommodating portion can be adjusted. The illumination 12 is fixed in the direction along the wall surface by the jig 15, and the light emitted from the illumination 12 appears along the wall surface as shown in FIG. As shown in FIGS. 3b and 3c, by tilting the surface of the jig 15, the illumination 12 can be adjusted so as to face the wall surface 1, that is, the light appears in a predetermined region 1b of the wall surface. The jig 15 is fixed to the vertical wall 17a1 of the partition wall by, for example, a fixing tool 26 such as a screw.
The lighting 12 is fixed to the jig 15 with an adhesive or the like. As a result, the lighting 12 can be replaced by removing the jig 15. In that case, the lighting 12 and the jig 15 are taken in and out from both ends of the hole 18 or the long base material 11. However, for example, the lighting 12 and the jig 15 may have a removable structure, such as providing locking claws that can engage with each other on the back surface of the lighting 12 and the front surface of the jig, and only the lighting 12 may be taken in and out.

このような間接照明装置１０は、例えば、壁面１に一定の間隔でも設けられた連結具２５を介して壁面１に取り付けられる（図１ａ、ｂ参照）。連結具２５としては、例えば、天面２５ａとその両端から垂直に延びる側面２５ｂとを有する断面コ字状の金具が挙げられる。このとき、連結具２５の側面２５ｂは壁面１に対して垂直に突出した状態となり、この側面２５ｂを長尺基材１１の周壁１６の開口した面１６ｃ（空間２０ｆ、２０ｇ）に挿入し、側面２５ｂと周壁１６の右側板１６ｂ２とを重ねてビス２６ａとナット２６ｂで固定する。
なお、連結具２５としては、壁面１に固定される壁面固定部（例えば、天面２５ａ）と、壁面１に対して突出する建材固定部（例えば、側面２５ｂ）とを備えていれば、その形状は特に限定されない。また、壁面固定部は、壁面に対して取り外し可能とせず、埋め込まれていてもよい。 Such an indirect lighting device 10 is attached to the wall surface 1 via, for example, a connector 25 provided on the wall surface 1 at regular intervals (see FIGS. 1a and 1b). Examples of the connecting tool 25 include a metal fitting having a U-shaped cross section having a top surface 25a and side surfaces 25b extending vertically from both ends thereof. At this time, the side surface 25b of the connector 25 is in a state of projecting perpendicularly to the wall surface 1, and the side surface 25b is inserted into the open surface 16c (space 20f, 20g) of the peripheral wall 16 of the long base material 11 to form the side surface. The 25b and the right side plate 16b2 of the peripheral wall 16 are overlapped and fixed with screws 26a and nuts 26b.
If the connecting tool 25 includes a wall surface fixing portion (for example, a top surface 25a) fixed to the wall surface 1 and a building material fixing portion (for example, a side surface 25b) protruding from the wall surface 1, the connector 25 may be provided. The shape is not particularly limited. Further, the wall surface fixing portion is not removable from the wall surface and may be embedded.

このように構成される間接照明装置１０は、建物の構造に関係無く壁面１に取り付けることができるため、デザイン性の高い間接照明を外壁に施すことができる。また間接照明装置１０は、耐熱性の高いセメント系材料によって構成されているため、発熱体である光源を直接収容しても、変形等が起こりにくい。また環境変化にも強く外部への設置にも適している。さらに、セメント系材料を押出成形したセメント系押出成形体に切削加工しているため、精度の高い製品を高効率で生産することができる。
また長尺基材１１の周壁１６において、穴１８が形成された左側板１６ｂ１と天板１６ａとが仕切壁１７によって連続しているため、長尺基材１１に所定の強度を保たせることができる。さらに、照明１２は、周壁１６の開口した面１６ｃとは連通しない独立した空間２０ａ（収容部）に収容されているため、間接照明装置１０の取付作業時に、照明１２に不意な外力を加えるおそれがなく好ましい。 Since the indirect lighting device 10 configured in this way can be attached to the wall surface 1 regardless of the structure of the building, indirect lighting with high design can be applied to the outer wall. Further, since the indirect lighting device 10 is made of a cement-based material having high heat resistance, even if a light source which is a heating element is directly accommodated, deformation or the like is unlikely to occur. It is also resistant to environmental changes and is suitable for external installation. Further, since the cement-based material is cut into an extruded cement-based extruded body, a highly accurate product can be produced with high efficiency.
Further, in the peripheral wall 16 of the long base material 11, the left side plate 16b1 on which the hole 18 is formed and the top plate 16a are continuous by the partition wall 17, so that the long base material 11 can maintain a predetermined strength. it can. Further, since the lighting 12 is housed in an independent space 20a (accommodation portion) that does not communicate with the open surface 16c of the peripheral wall 16, there is a possibility that an unexpected external force is applied to the lighting 12 when the indirect lighting device 10 is attached. It is preferable because there is no such thing.

なお、図１の間接照明装置１０の長尺基材１１の長手方向に垂直な断面のＣ状の周壁の形状は、壁面に取り付けられる周壁の一面（開口）以外に円または多角形で環状になっていれば、特に、限定されるものでない。例えば、周壁１６の天板１６ａは湾曲していてもよく、壁面に取り付けたとき壁面に対して角度を有していてもよく、側板１６ｂ１、１６ｂ２が壁面に対して垂直方向から角度を有していてもよい。さらに、半円状であってもよい。しかし、１面（開口面）が除かれた矩形であるものが好ましい。
仕切壁１７の配置も限定されるものではなく、少なくとも天板１６ａと側板１６ｂ１または１６ｂ２とが仕切壁１７によって連続していればよい。しかし、天板１６ａから延びる仕切壁と、側板１６ｂ１または１６ｂ２から延びる仕切壁とが交わるものが好ましい。さらに、長尺基材１１（天板１６ａ）の幅方向の中心線Ｃ１を中心として左右対称に設けられているものが好ましい。
図１の間接照明装置１０では、穴１８は長手方向の１本の長い穴を構成しているが、図４ａに示すように、複数本の穴１８を長手方向に並べるようにしてもよい。
図１の間接照明装置１０では、照明１２から直接照射した光を壁面に沿う方向または壁面に向かせているが、反射板等に反射させた光を壁面に沿う方向または壁面に向かせて、壁面の所定の領域に現れるようにしてもよい。
図１の間接照明装置１０では、照明１２は長尺基材１１と同じ長さにしているが、例えば、図４ｂに示すように、壁面へのデザインに応じて反射光の領域１ｃが長尺基材１１の長手方向の一部だけとなるように、照明１２を長尺基材１１の一部に設けてもよい。また図１の間接照明装置１０では、照明１２を左側にのみに設けているが、右側に設けても、図４ｃのように両側に設けてもよい。つまり、空間２０ａと空間２０ｃとに照明１２を設けてもよい。その場合、右側板１６ｂ２にも穴１８が設けられる。
さらに図１の間接照明装置１０では、照明１２の電源は、照明１２の端部に設けられた配線１２ｃを介して外部より供給しているが、長尺基材１１内に電池や配線等を設けて供給してもよい。その場合、電池等を長尺基材１１の他の空間（図２ａの空間２０ｂ等）に収容してもよい。 The shape of the C-shaped peripheral wall having a cross section perpendicular to the longitudinal direction of the long base material 11 of the indirect lighting device 10 in FIG. 1 is circular or polygonal in addition to one surface (opening) of the peripheral wall attached to the wall surface. If so, it is not particularly limited. For example, the top plate 16a of the peripheral wall 16 may be curved, may have an angle with respect to the wall surface when attached to the wall surface, and the side plates 16b1 and 16b2 may have an angle from the direction perpendicular to the wall surface. You may be. Further, it may be semicircular. However, a rectangle with one surface (open surface) removed is preferable.
The arrangement of the partition wall 17 is not limited, and at least the top plate 16a and the side plates 16b1 or 16b2 may be continuous by the partition wall 17. However, it is preferable that the partition wall extending from the top plate 16a intersects with the partition wall extending from the side plates 16b1 or 16b2. Further, it is preferable that the long base material 11 (top plate 16a) is provided symmetrically with respect to the center line C1 in the width direction.
In the indirect lighting device 10 of FIG. 1, the hole 18 constitutes one long hole in the longitudinal direction, but as shown in FIG. 4a, a plurality of holes 18 may be arranged in the longitudinal direction.
In the indirect lighting device 10 of FIG. 1, the light directly emitted from the lighting 12 is directed toward the wall surface or the wall surface, but the light reflected by the reflector or the like is directed toward the wall surface or the wall surface. It may appear in a predetermined area of the wall surface.
In the indirect lighting device 10 of FIG. 1, the lighting 12 has the same length as the long base material 11, but for example, as shown in FIG. 4b, the reflected light region 1c is long depending on the design on the wall surface. The illumination 12 may be provided on a part of the long base material 11 so that it is only a part of the base material 11 in the longitudinal direction. Further, in the indirect lighting device 10 of FIG. 1, the lighting 12 is provided only on the left side, but it may be provided on the right side or on both sides as shown in FIG. 4c. That is, the lighting 12 may be provided in the space 20a and the space 20c. In that case, the hole 18 is also provided in the right side plate 16b2.
Further, in the indirect lighting device 10 of FIG. 1, the power supply of the lighting 12 is supplied from the outside through the wiring 12c provided at the end of the lighting 12, but the battery, the wiring, and the like are placed in the long base material 11. It may be provided and supplied. In that case, the battery or the like may be housed in another space (space 20b or the like in FIG. 2a) of the long base material 11.

図５に示す間接照明装置３０は、周壁１６の左側板１６ｂ１に長手方向に延びる凹部３１が形成されている。そして、この凹部３１に照明１２が収容される。つまり、凹部３１が収容部となり、凹部３１の開口が収容部の開口となる。その他の構成については、図１の間接照明装置１０と実質的に同じものである。この場合も冶具を介して照明１２を固定してもよいが、照明１２が壁面に沿う方向または壁面に向くように、凹部３１に照明１２を直接固定している。このように凹部３１に照明１２を収容しても、図１の間接照明装置１０と同様に、デザイン性の高い間接照明を外壁に施すことができる。また左側板１６ｂ１に開口を形成しないため、長尺基材１１の強度が図１の間接照明装置１０より層高くなる。 In the indirect lighting device 30 shown in FIG. 5, a recess 31 extending in the longitudinal direction is formed in the left side plate 16b1 of the peripheral wall 16. Then, the illumination 12 is housed in the recess 31. That is, the recess 31 becomes the accommodating portion, and the opening of the recess 31 becomes the opening of the accommodating portion. Other configurations are substantially the same as those of the indirect lighting device 10 of FIG. In this case as well, the lighting 12 may be fixed via a jig, but the lighting 12 is directly fixed to the recess 31 so that the lighting 12 faces the wall surface or the wall surface. Even if the illumination 12 is accommodated in the recess 31 in this way, indirect illumination with high design can be applied to the outer wall as in the indirect illumination device 10 of FIG. Further, since no opening is formed in the left side plate 16b1, the strength of the long base material 11 is higher than that of the indirect lighting device 10 of FIG.

図６に示す間接照明装置４０は、周壁１６の左側板１６ｂ１の端部を切り落とされたものである。このように構成されているため、長尺基材１１を壁面１に取り付けたとき、長尺基材１１と壁面１との間に隙間４１が形成される。この間接照明装置４０は、この隙間４１に照明１２を固定するものである。つまり、周壁１６と壁面１とに囲まれた空間が収容部となり、隙間４１が収容部の開口となる。なお、図６の間接照明装置４０では、冶具１５を介して壁面１に固定している。しかし、周壁１６の左側板１６ｂ１の端部に固定してもよい。
この間接照明装置４０も、図１の間接照明装置１０と同様に、デザイン性の高い間接照明を外壁に施すことができる。またこの間接照明装置４０も、周壁１６の端部を切り落としているだけであるため、図１の間接照明装置１０よりも長尺基材１１の強度を高く保つことができる。 In the indirect lighting device 40 shown in FIG. 6, the end portion of the left side plate 16b1 of the peripheral wall 16 is cut off. Due to this structure, when the long base material 11 is attached to the wall surface 1, a gap 41 is formed between the long base material 11 and the wall surface 1. The indirect lighting device 40 fixes the lighting 12 in the gap 41. That is, the space surrounded by the peripheral wall 16 and the wall surface 1 serves as the accommodating portion, and the gap 41 serves as the opening of the accommodating portion. In the indirect lighting device 40 of FIG. 6, it is fixed to the wall surface 1 via a jig 15. However, it may be fixed to the end of the left side plate 16b1 of the peripheral wall 16.
Similar to the indirect lighting device 10 of FIG. 1, the indirect lighting device 40 can also apply highly designed indirect lighting to the outer wall. Further, since the indirect lighting device 40 also only cuts off the end portion of the peripheral wall 16, the strength of the long base material 11 can be maintained higher than that of the indirect lighting device 10 of FIG.
