このように従来では装飾体を保持する機能と周囲を照らす機能の一方のみを有するものがあったが、両機能を併せ持つものはなく、両機能が必要な場合は夫々を別個に設置する必要があった。   As described above, there has been one that has only one of the function of holding the decorative body and the function of illuminating the surroundings, but there is no one that has both functions, and if both functions are required, it is necessary to install each separately. there were.

本発明は上記従来の事情に鑑みてなされたものであって、装飾体を保持する機能と発光機能を併せ持つ面発光建築用パネルを提供することを課題とする。   This invention is made | formed in view of the said conventional situation, Comprising: It aims at providing the panel for surface emitting construction which has a function which hold | maintains a decorative body, and a light emission function.

上記課題を解決するために、本発明は略矩形板状でその背面側を屋内空間の壁又は天井の内装面に沿わせて設置される面発光建築用パネルを提供するものであって、該面発光建築用パネルは以下の特徴的な構成を有している。端面から入射した光を前面から出射して面状に発光する透明な導光板６と、該導光板６の端面に光を照射する光源７と、導光板６の背方に設けられて面状の装飾体５を導光板６の背面と略平行に保持する装飾体保持部を備える。前記導光板６が発光したときに装飾体保持部に収納された装飾体５が導光板６を介して視認されないようにする。   In order to solve the above-described problems, the present invention provides a surface-emitting building panel that is installed in a substantially rectangular plate shape with its back side along an interior surface of a wall or ceiling of an indoor space, The surface-emitting building panel has the following characteristic configuration. A transparent light guide plate 6 that emits light incident from the end surface from the front surface and emits light in a planar shape, a light source 7 that irradiates light to the end surface of the light guide plate 6, and a planar shape provided behind the light guide plate 6 The decorative body 5 is provided with a decorative body holding section that holds the decorative body 5 substantially parallel to the back surface of the light guide plate 6. The decorative body 5 accommodated in the decorative body holding portion is prevented from being visually recognized through the light guide plate 6 when the light guide plate 6 emits light.

また、本発明においては、前記装飾体５と導光板６の間に光通過層が形成され、該光通過層の外周の一部から光を導入する装飾体用光源８が設けられることが好ましい。   In the present invention, it is preferable that a light passing layer is formed between the decorative body 5 and the light guide plate 6 and a decorative body light source 8 for introducing light from a part of the outer periphery of the light passing layer is provided. .

また、本発明においては、前記装飾体保持部から装飾体５を出し入れ可能とすることが好ましい。   In the present invention, it is preferable that the decorative body 5 can be taken in and out from the decorative body holding portion.

本発明にあっては導光板の背方に設けられた装飾体保持部にて装飾体を保持することができる。そして、昼等の周囲が明るい状態にあるときにおいて導光板を非発光状態にした場合には、透明な導光板を通して装飾体を視認することができる。一方、夜等の周囲が暗い状態にあるときにおいて光源を発光させることで導光板を面状に発光させることができ、この場合は導光板を通して装飾体が見えなくなる。したがって、光源を非発光状態とすることにより装飾体を鑑賞することが可能となって鑑賞用に利用することができ、光源を発光させることにより周囲を照らす照明として利用することができる。   In this invention, a decoration body can be hold | maintained in the decoration body holding part provided in the back of the light-guide plate. When the light guide plate is in a non-light-emitting state when the surroundings are bright such as in the daytime, the decorative body can be visually recognized through the transparent light guide plate. On the other hand, when the surroundings are dark, such as at night, the light guide plate can emit light in a planar shape by emitting light from the light source. In this case, the decorative body cannot be seen through the light guide plate. Therefore, it is possible to appreciate the decorative body by setting the light source in a non-light emitting state, and it can be used for viewing, and can be used as illumination for illuminating the surroundings by emitting light.

また、装飾体と導光板の間に光通過層を形成し、該光通過層の外周の一部から光を導入する装飾体用光源を設けることにより、装飾体用光源から光通過層に導入された発光で装飾体の前面を照らして、導光板を通して視認される装飾体を演出することができる。   In addition, a light passage layer is formed between the decoration body and the light guide plate, and a light source for decoration body that introduces light from a part of the outer periphery of the light passage layer is provided, so that the light source for decoration body is introduced into the light passage layer. Illuminating the front surface of the decorative body with the emitted light, it is possible to produce a decorative body visually recognized through the light guide plate.

以下、本発明の実施形態について添付図面に基づいて説明する。   Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

図１乃至図９に本実施形態の一例の面発光建築用パネル１を示す。本例の面発光建築用パネル１は、図２のように、全体として略矩形板状に形成され、その背面側を建物の廊下や玄関、部屋等の壁２に沿わせて設置されるものであって、主に壁２と反対側となる前面側を照らすものである。   FIG. 1 to FIG. 9 show a surface-emitting building panel 1 as an example of this embodiment. As shown in FIG. 2, the surface emitting building panel 1 of this example is formed in a substantially rectangular plate shape as a whole, and the back side thereof is installed along the wall 2 of the hallway, entrance, room, etc. of the building. However, it mainly illuminates the front side opposite to the wall 2.

図３のように、面発光建築用パネル１は、壁２の室内側の面となる壁面２ａに取り付けられる略矩形板状の取り付けベース３と、該取り付けベース３によって保持される矩形状の下地板４、矩形面状の装飾体５、矩形状の導光板６、及び光源７、８（図１参照）を備えている。   As shown in FIG. 3, the surface-emitting building panel 1 includes a substantially rectangular plate-shaped mounting base 3 that is attached to a wall surface 2 a that is a room-side surface of the wall 2, and a rectangular bottom that is held by the mounting base 3. A ground plate 4, a rectangular-shaped decorative body 5, a rectangular light guide plate 6, and light sources 7 and 8 (see FIG. 1) are provided.

下地板４は取り付けベース３の前面に沿って配置され、装飾体５は下地板４の前面に沿って配置される。また、導光板６は装飾体５の前面に沿って配置され、これにより下地板４、装飾体５、導光板６は壁面に沿って配置されることとなる。光源７、８のうち、一方の光源は導光板６の端面に光を照射して導光板６を面状に発光させる導光板用光源７であり、他方の光源は装飾体５を照らす装飾体用光源８である。   The base plate 4 is disposed along the front surface of the mounting base 3, and the decorative body 5 is disposed along the front surface of the base plate 4. Further, the light guide plate 6 is disposed along the front surface of the decorative body 5, whereby the base plate 4, the decorative body 5, and the light guide plate 6 are disposed along the wall surface. Of the light sources 7 and 8, one light source is a light guide plate light source 7 that irradiates light on the end surface of the light guide plate 6 to cause the light guide plate 6 to emit light in a planar shape, and the other light source is a decorative body that illuminates the decorative body 5. The light source 8 is used.

図５のように、取り付けベース３はアルミ等の金属板や合成樹脂板で構成されている。取り付けベース３の壁面２ａに沿う背板部９の四隅にはねじ用孔１０が設けられている。取り付けベース３を壁２に取り付けるには、取り付けベース３の前方から各ねじ用孔１０にねじ１１を挿通し、各ねじ１１を壁２に固着する。   As shown in FIG. 5, the mounting base 3 is made of a metal plate such as aluminum or a synthetic resin plate. Screw holes 10 are provided at the four corners of the back plate portion 9 along the wall surface 2 a of the mounting base 3. In order to attach the attachment base 3 to the wall 2, screws 11 are inserted into the screw holes 10 from the front of the attachment base 3, and the screws 11 are fixed to the wall 2.

背板部９の両側縁には前方に突出する側縁片部１２ａ、１２ｂが全長に亘って形成されている。   Side edge pieces 12a and 12b projecting forward are formed on both side edges of the back plate portion 9 over the entire length.

下地板４はその背面が取り付けベース３の背板部９の前面に当接し、且つ、両側の側縁片部１２ａ、１２ｂの間に嵌め込まれた状態で取り付けベース３に固定される。なお、下地板４は取り付けベース３に接着してもよい。   The base plate 4 is fixed to the mounting base 3 with its back surface in contact with the front surface of the back plate portion 9 of the mounting base 3 and fitted between the side edge pieces 12a, 12b on both sides. The base plate 4 may be bonded to the mounting base 3.

図３のように下地板４の前面の上下の縁部の夫々には全長に亘って長尺な透光材１３が接着等により取り付けられる。   As shown in FIG. 3, a long translucent material 13 is attached to each of the upper and lower edges of the front surface of the base plate 4 by bonding or the like over the entire length.

導光板６はアクリルやガラス等の透明な材料により形成され、上端面が前記導光板用光源７から発せられた光が導入される入射面となり、前面及び両側端面が前記入射面から導入された光を出射する出射面となっている。   The light guide plate 6 is formed of a transparent material such as acrylic or glass, the upper end surface is an incident surface into which light emitted from the light source 7 for the light guide plate is introduced, and the front surface and both end surfaces are introduced from the incident surface. It is an emission surface that emits light.

導光板６の外周端面の適宜箇所には導光板６に入射した光を反射して前記出射面へと導く鏡面加工が施されている。また、導光板６の背面には光拡散性を高めて前記出射面から主に光を出射するために導光パターンが形成されているが、該導光パターンは導光板６の透明度を高めるため、φ０．１ｍｍ程度の微小な印刷ドットや微小プリズム等からなるものや、透明度の高い光拡散インクを導光板６に施すこと等により形成される。つまり、導光板６の背面は透明で背方の装飾体５を視認できる程度の透明性を有し且つ光拡散性の高い光拡散面となっている。   Mirror processing is performed at appropriate locations on the outer peripheral end surface of the light guide plate 6 to reflect the light incident on the light guide plate 6 and guide it to the exit surface. In addition, a light guide pattern is formed on the back surface of the light guide plate 6 in order to increase light diffusibility and mainly emit light from the light exit surface. The light guide pattern increases the transparency of the light guide plate 6. In addition, the light guide plate 6 is formed by applying a light diffusing ink having a high transparency to a fine print dot or a micro prism having a diameter of about 0.1 mm. That is, the back surface of the light guide plate 6 is transparent and has a light diffusing surface that is transparent enough to visually recognize the back decorative body 5 and has high light diffusibility.

取り付けベース３の両側端には導光板６を固定するため固定手段１４、１５が夫々形成されている。   Fixing means 14 and 15 are formed on both ends of the mounting base 3 to fix the light guide plate 6, respectively.

各固定手段１４、１５は、側縁片部１２ａ、１２ｂの上端部及び下端部を前方に延出して形成した突片部１６と、上の突片部１６の前縁から内側方に向けて突出した押さえ片部１７で構成されている。   Each of the fixing means 14 and 15 has a projecting piece portion 16 formed by extending the upper end and lower end of the side edge piece portions 12a and 12b forward, and from the front edge of the upper projecting piece portion 16 toward the inside. It is composed of a protruding pressing piece 17.

導光板６は、その背面の上下の縁部が対応する透光材１３の前面に接着されると共に、前面の上縁部の両側端部が対応する押さえ片部１７の背面に沿い、且つ、両側の側端面が対応する突片部１６に沿った状態で、取り付けベース３に固定される。   The light guide plate 6 is bonded to the front surface of the corresponding translucent material 13 at the upper and lower edges of the back surface, and both side ends of the upper edge portion of the light guide plate 6 are along the back surface of the corresponding pressing piece 17 and The side end surfaces on both sides are fixed to the mounting base 3 in a state along the corresponding projecting piece portions 16.

このように導光板６を透光材１３を介して下地板４の前面に設けることで、導光板６は下地板４の前方に隙間１８を介して配置される。すなわち、上下の透光材１３は導光板６を隙間１８を介して下地板４に設置するためのスペーサ部材を構成する。   Thus, by providing the light guide plate 6 on the front surface of the base plate 4 via the translucent material 13, the light guide plate 6 is disposed in front of the base plate 4 via the gap 18. That is, the upper and lower light-transmitting materials 13 constitute a spacer member for installing the light guide plate 6 on the base plate 4 through the gap 18.

図６及び図７に示すように、導光板６の出射面の一部を構成する両側の側端面は対応する固定手段１４、１５の上下の突片部１６の間に形成された空所２０を介して外側方に露出し、両外側方にも光を出射する。   As shown in FIGS. 6 and 7, the side end surfaces on both sides constituting a part of the exit surface of the light guide plate 6 are voids 20 formed between the upper and lower projecting pieces 16 of the corresponding fixing means 14, 15. It is exposed to the outside through the light and emits light to both the outside.

装飾体５は前記隙間１８に配置され、下地板４の前面に沿い、且つ、導光板６の背面と略平行にされた状態で保持される。つまり、本例では隙間１８を形成する透光材１３、導光板６及び下地板４で装飾体保持部が構成されている。   The decorative body 5 is disposed in the gap 18 and is held along the front surface of the base plate 4 and substantially parallel to the back surface of the light guide plate 6. That is, in this example, the decorative body holding portion is configured by the translucent material 13, the light guide plate 6, and the base plate 4 that form the gap 18.

装飾体５は、写真や絵画等からなる前面に装飾を施したシート状の装飾物と、該装飾物が抜き差し自在に挿入される透明なシート状フォルダーで構成され、面状に形成される。なお、装飾体５はこれに限定されず、写真や絵画等からなるシート状装飾物そのものや、板状の装飾物等であってもよい。   The decorative body 5 is composed of a sheet-like decoration with decoration on the front surface made of a photograph, a painting, and the like, and a transparent sheet-like folder into which the decoration is removably inserted, and is formed in a planar shape. Note that the decorative body 5 is not limited to this, and may be a sheet-like ornament itself made of a photograph, a picture, or the like, a plate-like ornament, or the like.

図１に示すように、各透光材１３の前部には他方の透光材１３側に向かって突出する突出部２１が形成され、突出部２１と後方の下地板４の間には差込溝２２が形成されている。前記装飾体５の上下の縁部は対応する差込溝２２に挿入される。該装飾体５と前方の導光板６の間には光通過層を構成する空気層２３が形成される。   As shown in FIG. 1, a protrusion 21 that protrudes toward the other light-transmitting material 13 is formed at the front portion of each light-transmitting material 13, and there is a difference between the protrusion 21 and the rear base plate 4. A recessed groove 22 is formed. The upper and lower edges of the decorative body 5 are inserted into the corresponding insertion grooves 22. An air layer 23 constituting a light passage layer is formed between the decorative body 5 and the front light guide plate 6.

装飾体５は以下の構成により図８のように前記隙間１８に面発光建築用パネル１の外側方から出し入れ自在に収納される。   The decorative body 5 is housed in the gap 18 so as to be freely inserted and removed from the outer side of the surface emitting building panel 1 as shown in FIG.

取り付けベース３の両側の側縁片部１２ａ、１２ｂのうち、一方の側縁片部１２ａは他方の側縁片部１２ｂよりも前方への突出長さが短くなっている。側縁片部１２ａから前方の突出する上下の突片部１６ａの後端部には空所２０側（他方の突片部１６ａ側）に向かって開口する切欠２４が形成され、各切欠２４は前記差込溝２２の一側端部に連通している。   Of the side edge pieces 12a and 12b on both sides of the mounting base 3, one side edge piece 12a has a shorter forward protrusion length than the other side edge piece 12b. A notch 24 is formed at the rear end portion of the upper and lower protruding piece portions 16a protruding forward from the side edge piece portion 12a. The cutout 24 opens toward the space 20 side (the other protruding piece portion 16a side). The insertion groove 22 communicates with one end of the insertion groove 22.

隙間１８は前記切欠２４が形成された上下の突片部１６ａの後端部の間の空所を介して外側方に開口し、この空所を介して装飾体５は前記隙間１８に出し入れされる。このとき、導光板６は上下の縁部を対応する切欠２４や差込溝２２に挿入した状態で左右方向にスライドして抜き差しできるようになっている。このように面発光建築用パネル１から装飾体５を出し入れ自在とすることで、装飾体５を別の装飾体に容易に交換することができ、飽きのこないものとすることができる。   The gap 18 opens outwardly through a space between the rear end portions of the upper and lower protruding piece portions 16a in which the notches 24 are formed, and the decorative body 5 is taken in and out of the gap 18 through this space. The At this time, the light guide plate 6 can be slid in the left-right direction with the upper and lower edges inserted into the corresponding notches 24 and the insertion grooves 22 and can be inserted and removed. Thus, by making the decorative body 5 freely removable from the surface-emitting building panel 1, the decorative body 5 can be easily replaced with another decorative body, and it is possible to keep timeless.

取り付けベース３の上端部には両側端部を除いて基板取付部２６が形成されている。基板取付部２６は背板部９の上縁から前側に向けて突設され、側断面Ｌ字状に形成されている。   A board mounting portion 26 is formed on the upper end portion of the mounting base 3 except for both end portions. The board attaching part 26 is provided so as to project from the upper edge of the back plate part 9 toward the front side, and is formed in an L-shaped side section.

図４のように、基板取付部２６の前面には、側断面が基板取付部２６と逆向きのＬ字状をした取付具２７が取り付けられる。この取付具２７の下面には左右に長尺な回路基板２８が取り付けられている。   As shown in FIG. 4, an attachment 27 having an L shape whose side section is opposite to the substrate attachment portion 26 is attached to the front surface of the substrate attachment portion 26. A circuit board 28 that is long on the left and right is attached to the lower surface of the fixture 27.

回路基板２８の前部には導光板６に光を照射して導光板６を面状に発光させる導光板用光源７として発光ダイオード７ａが左右方向に複数並べて実装されている。   A plurality of light emitting diodes 7 a are mounted in the front and rear of the circuit board 28 as light guide plate light sources 7 that emit light onto the light guide plate 6 to emit light in a planar shape.

導光板６の入射面を構成する上端面は前記導光板用光源７を構成する各発光ダイオード７ａの下方に位置し対向する。各発光ダイオード７ａから下方に向けて発せられた光は導光板６の上端面から導光板６に入射し、この後、導光板６の前面及び両側の側端面から出射する。これにより導光板６が略全体に亘って発光する。   The upper end surface constituting the incident surface of the light guide plate 6 is located below and faces each light emitting diode 7a constituting the light source 7 for the light guide plate. Light emitted downward from each light-emitting diode 7 a enters the light guide plate 6 from the upper end surface of the light guide plate 6, and then exits from the front surface and both side end surfaces of the light guide plate 6. Thereby, the light guide plate 6 emits light over substantially the whole.

回路基板２８の後部には、装飾体５を照らす装飾体用光源８として発光ダイオード８ａが左右方向に複数並べて実装されている。なお、図示例の発光ダイオード７ａ及び発光ダイオード８ａは前後に並べて設けられている。上下の透光材１３のうち、上の透光材１３の前部は、図１のように前記装飾体用光源８を構成する各発光ダイオード８ａの下方に位置し対向する。   A plurality of light emitting diodes 8 a are mounted in the left-right direction on the rear portion of the circuit board 28 as decorative body light sources 8 that illuminate the decorative body 5. In the illustrated example, the light emitting diode 7a and the light emitting diode 8a are provided side by side. Of the upper and lower translucent members 13, the front part of the upper translucent member 13 is positioned below and faces each light emitting diode 8a constituting the decorative body light source 8 as shown in FIG.

各発光ダイオード８ａから下方に向けて発せられた光は図１の矢印に示すように透光材１３を透過した後、前記装飾体５と導光板６の間に形成された空気層２３に至り、該空気層２３を介して装飾体５の前面に照射される。これにより、装飾体５の前面は略全体に亘って照らされる。   Light emitted downward from each light-emitting diode 8 a passes through the light-transmitting material 13 as indicated by the arrow in FIG. 1 and then reaches the air layer 23 formed between the decorative body 5 and the light guide plate 6. The front surface of the decorative body 5 is irradiated through the air layer 23. Thereby, the front surface of the decorative body 5 is illuminated over substantially the whole.

また、取り付けベース３の上縁部及び下縁部には全長に亘る断面Ｌ字状の縁材３１が夫々取り付けられる。図２のように、各縁材３１によって、導光板６の上下の縁部や、取り付けベース３の上下の縁部、取り付けベース３に設けられた取付具２７、回路基板２８、光源７、８、ねじ１１、下端部に設けられる電源ユニット３２等が覆い隠され、面発光建築用パネル１の前面における両縁材３１の間においては導光板６の前面のみが露出した状態となる。   Further, an edge member 31 having an L-shaped cross section over the entire length is attached to the upper edge portion and the lower edge portion of the attachment base 3. As shown in FIG. 2, the upper and lower edges of the light guide plate 6, the upper and lower edges of the mounting base 3, the fixture 27 provided on the mounting base 3, the circuit board 28, and the light sources 7 and 8 are provided by the respective edge members 31. The screw 11, the power supply unit 32 and the like provided at the lower end are covered and hidden, and only the front surface of the light guide plate 6 is exposed between both edge members 31 on the front surface of the panel 1 for surface emitting construction.

面発光建築用パネル１は、両光源７、８を消灯するＯＦＦモードと、両光源７、８のうち導光板用光源７のみを発光させて導光板６を面状に発光させる通常発光モードと、装飾体用光源８のみを発光させて装飾体５を演出する演出発光モードとからなる切替可能な３つのモードを備えている。   The surface-emitting building panel 1 includes an OFF mode in which both the light sources 7 and 8 are turned off, and a normal light-emitting mode in which only the light guide plate light source 7 out of both the light sources 7 and 8 emits light and the light guide plate 6 emits light in a planar shape. In addition, there are provided three switchable modes consisting of an effect light emission mode in which only the decorative body light source 8 emits light to produce the decorative body 5.

ＯＦＦモードでは、光源７、８を構成する各発光ダイオード７ａ、８ａが消灯状態となる。このため、面発光建築用パネル１を前方から見た場合には、非発光状態にある導光板６を通して装飾体５の前面を視認することができ、装飾体５を鑑賞することができる。   In the OFF mode, the light emitting diodes 7a and 8a constituting the light sources 7 and 8 are turned off. For this reason, when the surface emitting building panel 1 is viewed from the front, the front surface of the decorative body 5 can be visually recognized through the light guide plate 6 in a non-light emitting state, and the decorative body 5 can be viewed.

通常発光モードでは、導光板用光源７を構成する各発光ダイオード７ａが発光状態となり、前述のように導光板６の入射面から導入された光はそのほとんどが出射面から出射されて導光板６が面状に発光する。このため、面発光建築用パネル１により周辺を照らすことができ、照明として利用できる。また、この通常発光モードでは、導光板６が発光するのに対して装飾体５は装飾体用光源８により照らされないので、この光のコントラストにより装飾体５の前面を面発光建築用パネル１の前方から導光板６を通して視認することができない状態となる。つまり、本例の面発光建築用パネル１にあっては、導光板６を非発光状態として装飾体５を見えるようにしたり、導光板６を発光させることにより装飾体５が見えないようにしたりすることができる。なお、この通常発光モードでは、図９のように光を導光板６の前面に加えて両側の側端面からも出射することができ、左右方向の幅広い範囲を照らすことができる。   In the normal light emission mode, each light emitting diode 7a constituting the light source 7 for the light guide plate is in a light emitting state, and most of the light introduced from the incident surface of the light guide plate 6 is emitted from the output surface as described above. Emits light in a planar shape. For this reason, the surface emitting architectural panel 1 can illuminate the surroundings and can be used as illumination. Moreover, in this normal light emission mode, since the light guide plate 6 emits light, the decorative body 5 is not illuminated by the light source 8 for decorative body. It will be in the state which cannot be visually recognized through the light-guide plate 6 from the front. That is, in the surface-emitting building panel 1 of this example, the decorative body 5 is made visible by setting the light guide plate 6 to the non-light emitting state, or the decorative body 5 is made invisible by causing the light guide plate 6 to emit light. can do. In this normal light emission mode, light can be emitted from both side end surfaces in addition to the front surface of the light guide plate 6 as shown in FIG. 9, and a wide range in the left-right direction can be illuminated.

演出発光モードでは、装飾体用光源８を構成する各発光ダイオード８ａが発光状態となり、前述のように装飾体５の前面が照らされる。この演出発光モードにおいて面発光建築用パネル１を前側から見ると、非発光状態にある導光板６を通して、前記装飾体用光源８で照らされた装飾体５の前面を視認することができる。   In the effect light emission mode, each light emitting diode 8a constituting the decorative body light source 8 is in a light emitting state, and the front surface of the decorative body 5 is illuminated as described above. When the surface light emitting building panel 1 is viewed from the front side in this effect light emission mode, the front surface of the decorative body 5 illuminated by the decorative body light source 8 can be visually recognized through the light guide plate 6 in a non-light emitting state.

なお、前記モードの切替は手動で行うものであってもよいし、面発光建築用パネル１の下端部に設けられる照度センサーや人体検知センサー等からなるセンサー３５の検出結果に基づいて自動で行えるようにしてもかまわない。   The mode switching may be performed manually or automatically based on the detection result of the sensor 35 including an illuminance sensor or a human body detection sensor provided at the lower end portion of the surface emitting building panel 1. It doesn't matter if you do.

以上説明した面発光建築用パネル１は、装飾体保持部にて装飾体５を保持することができる。そして、夜等の周囲が暗いときには通常発光モードとして周辺を照らすことができる。また、昼等の周囲が明るいときにはＯＦＦモードに、夜等の周囲が暗いときには演出発光モードに切り替えて導光板６を非発光状態とすることで、透明な導光板６を通して装飾体５を視認可能な状態とすることができる。   The surface-emitting building panel 1 described above can hold the decorative body 5 by the decorative body holding portion. When the surroundings are dark, such as at night, the surroundings can be illuminated as a normal light emission mode. Further, the decorative body 5 can be visually recognized through the transparent light guide plate 6 by switching to the OFF mode when the surroundings are bright such as daytime and switching to the effect light emitting mode when the surroundings are dark such as night and making the light guide plate 6 non-light emitting. It can be in a state.

また、演出発光モードに切り替えた場合、装飾体用光源８から発せられた光を直接空気層２３の外周の一部から導入して装飾体５の前面を照らすことができ、装飾体用光源８の光で装飾体５を照らし、演出効果を得ることができる。   Further, when the effect light emission mode is switched, the light emitted from the decorative body light source 8 can be directly introduced from a part of the outer periphery of the air layer 23 to illuminate the front surface of the decorative body 5. Illuminating the decorative body 5 with the light, it is possible to obtain a production effect.

次に他例の面発光建築用パネル１について説明する。なお、以下の説明では前記一例の面発光建築用パネル１と同一の構成については同一の番号を付与し、重複する説明は省略する。   Next, another example of the surface-emitting building panel 1 will be described. In addition, in the following description, the same number is attached | subjected about the structure same as the surface emitting construction panel 1 of the said example, and the overlapping description is abbreviate | omitted.

図１０に示す他例の面発光建築用パネル１は、装飾体用光源８、光通過層を構成する空気層２３、透光材１３を有しておらず、導光板６の背面を下地板４よりも薄い板状の装飾体５の前面に接着又は当接している。つまり、この場合は、導光板６及び下地板４にて面状の装飾体５を導光板６の背面に沿って保持する装飾体保持部が構成される。なお、本例でも下地板４及び導光板６の夫々を取り付けベース３に固定する等して、装飾体５を導光板６と下地板４の間に形成される隙間に出し入れ自在に収納してもかまわない。   The surface emitting building panel 1 of another example shown in FIG. 10 does not have the decorative body light source 8, the air layer 23 constituting the light passage layer, and the translucent material 13, and the back surface of the light guide plate 6 is the base plate. The plate-like decorative body 5 thinner than 4 is adhered or abutted on the front surface. That is, in this case, the decorative body holding portion that holds the planar decorative body 5 along the back surface of the light guide plate 6 is configured by the light guide plate 6 and the base plate 4. In this example as well, each of the base plate 4 and the light guide plate 6 is fixed to the mounting base 3 so that the decorative body 5 can be freely put in and out of the gap formed between the light guide plate 6 and the base plate 4. It doesn't matter.

本例の面発光建築用パネル１にあっても、導光板用光源７を発光して導光板６を発光させることにより面発光建築用パネル１の周辺を照らすことができ、尚且つ、導光板用光源７を消灯して導光板６を非発光状態とすることにより透明な導光板６を通して装飾体５を視認可能な状態とすることができる。   Even in the surface-emitting building panel 1 of this example, the periphery of the surface-emitting building panel 1 can be illuminated by emitting light from the light source 7 for the light guide plate and causing the light guide plate 6 to emit light. The decorative body 5 can be made visible through the transparent light guide plate 6 by turning off the light source 7 and making the light guide plate 6 non-light emitting.

なお、前記一例の面発光建築用パネル１は、透光材１３を下地板４の縁部に亘って設けたが、下地板４の縁部に沿って複数並べて設けてもよい。特にこの場合、透光材１３を装飾体用光源８の光が通過しない位置に配置することもでき、この場合は透光材１３は光が透過しない材料により形成することもできる。   In addition, although the panel 1 for surface emitting construction of the above example has the translucent material 13 provided over the edge of the base plate 4, a plurality of the light-transmitting materials 13 may be provided side by side along the edge of the base plate 4. In particular, in this case, the light-transmitting material 13 can be disposed at a position where the light from the decorative body light source 8 does not pass. In this case, the light-transmitting material 13 can also be formed of a material that does not transmit light.

また、前記各例の面発光建築用パネル１は、導光板６の一辺を構成する上端面を入射面としたが、導光板６の他のいずれの辺を構成する端面を入射面としてもよく、また、複数の辺を入射面としてもよい。また、導光板６の前面及び両側の側端面を出射面としたが、前面のみを出射面としたり、前面及び上下の端面を出射面としてもよく、すなわち、導光板６の少なくとも前面が出射面であればよい。   Moreover, although the upper surface which comprises one side of the light-guide plate 6 was made into the entrance plane, the surface emitting construction panel 1 of each said example is good also considering the end surface which comprises any other side of the light-guide plate 6 as an entrance plane. In addition, a plurality of sides may be used as the incident surface. Moreover, although the front surface of the light guide plate 6 and the side end surfaces on both sides are used as the output surfaces, only the front surface may be used as the output surface, or the front surface and the upper and lower end surfaces may be used as the output surfaces. If it is.

また、装飾体５は上方や下方から面発光建築用パネル１に出し入れ可能に収納されるものであってもよい。   Further, the decorative body 5 may be housed so as to be able to be inserted into and removed from the surface emitting building panel 1 from above or below.

また、光通過層を空気層２３で構成したが、透明な部材により構成してもよい。また、装飾体用光源８から発せられた光の光通過層への導入方向は側方や下方からであってもよく、つまり光通過層から導光板６の厚み方向と直交する方向に離れた箇所に装飾体用光源８を配置し、ここから発した光を光通過層の外周部の一部に導入し、光通過層を介して装飾体５を照らすものであればよい。   Moreover, although the light passage layer was comprised with the air layer 23, you may comprise with a transparent member. In addition, the direction in which the light emitted from the decorative body light source 8 is introduced into the light passage layer may be from the side or from below, that is, away from the light passage layer in a direction perpendicular to the thickness direction of the light guide plate 6. The decorative body light source 8 may be arranged at a location, light emitted therefrom may be introduced into a part of the outer peripheral portion of the light passage layer, and the decoration body 5 may be illuminated through the light passage layer.

また、導光板用光源７及び装飾体用光源８は長尺な蛍光ランプ等、発光ダイオード以外の他の光源により構成してもかまわない。   Further, the light source 7 for the light guide plate and the light source 8 for the decorative body may be composed of a light source other than the light emitting diode such as a long fluorescent lamp.

さらに、面発光建築用パネル１は屋内空間の壁面に設けたが、天井に設けられるものであってもよい。   Furthermore, although the surface emitting building panel 1 is provided on the wall surface of the indoor space, it may be provided on the ceiling.
