以下、本発明の実施の形態を図面に基づいて説明する。このルーバーは、建築物の窓の室外側に設置するものであり、以下において、左右とは、ルーバーを室外側から見た場合の左右方向（図２の左右方向）を示すものとする。ルーバーの第一実施形態は、図１及び図２に示すように、矩形の枠体１０を有し、枠体１０の内周側に、傾斜ルーバー１と、くし形ルーバー２を備えている。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. This louver is installed on the outdoor side of the window of the building, and in the following, the left and right means the left-right direction (the left-right direction in FIG. 2) when the louver is viewed from the outdoor side. As shown in FIGS. 1 and 2, the first embodiment of the louver has a rectangular frame body 10, and includes an inclined louver 1 and a comb-shaped louver 2 on the inner peripheral side of the frame body 10.

傾斜ルーバー１は、上下方向に延びるものであって、複数本を見付方向（左右方向）に等間隔に並べて、枠体１０の上下に固定してある。各傾斜ルーバー１は、中空形材からなるものであって、室外側から室内側に向けて、見込方向（室内外方向）に対して左に傾斜しており、見込方向に対して傾斜する室外側面１１及び室内側面１２と、室外側の見付面１３を有する。さらに、図１に示す傾斜ルーバー１の水平方向断面形状について詳述すると、室外側面１１は、放物線形状となっており、室外側端が放物線の頂点であって、ルーバーの室外側面上（見付面１３と面一な面上）の、傾斜ルーバー１同士の隙間の左右方向中央に、放物線の焦点が位置している。一方、室内側面１２は、室外側部分が略直線形状で、室内側部分が室外側面１１と略同一の室内側に向けてわずかに凸な曲線形状となっている。そして、室外側面１１及び見付面１３は、平滑で、光の反射率が高く正反射成分の比率が大きな面であるのに対し、室内側面１２は、ローレット加工により細かい凹凸を形成してあり、光を拡散反射する面である。また、室外側面１１の室内側端部には、室外側に向けて開口し上下に延びる溝状の室内側被係合部１４を形成してあり、室内側面１２の室外側端部には、室内側に向けて開口し上下に延びる溝状の室外側被係合部１５を形成してある。なお、隣接する傾斜ルーバー１において、左側の傾斜ルーバー１の右端部（室外側端部）と右側の傾斜ルーバー１の左端部（室内側端部）の左右位置が一致している。 The inclined louvers 1 extend in the vertical direction, and a plurality of inclined louvers 1 are arranged at equal intervals in the finding direction (horizontal direction) and fixed to the top and bottom of the frame body 10. Each inclined louver 1 is made of a hollow profile, and is inclined to the left with respect to the expected direction (indoor / outdoor direction) from the outdoor side to the indoor side, and is inclined with respect to the expected direction. It has a side surface 11, an indoor side surface 12, and an outdoor side finding surface 13. Further, the horizontal cross-sectional shape of the inclined louver 1 shown in FIG. 1 will be described in detail. The outdoor surface 11 has a parabolic shape, the outdoor end is the apex of the parabola, and the outdoor surface of the louver is on the outdoor surface (found). The focal point of the parabola is located at the center of the gap between the inclined louvers 1 in the left-right direction on the surface (on a plane flush with the surface 13). On the other hand, the indoor side surface 12 has a substantially straight line shape on the outdoor side portion, and the indoor side portion has a curved shape slightly convex toward the indoor side, which is substantially the same as the outdoor side surface 11. The outdoor side surface 11 and the finding surface 13 are smooth, have high light reflectance and a large proportion of specular reflection components, while the indoor side surface 12 is formed with fine irregularities by knurling. , A surface that diffuses and reflects light. Further, a groove-shaped indoor side engaged portion 14 that opens toward the outdoor side and extends vertically is formed at the indoor side end portion of the outdoor side surface 11, and the outdoor side end portion of the indoor side surface 12 is formed. A groove-shaped outdoor engaged portion 15 that opens toward the indoor side and extends vertically is formed. In the adjacent inclined louver 1, the left and right positions of the right end portion (outdoor end portion) of the left inclined louver 1 and the left end portion (indoor side end portion) of the right inclined louver 1 are the same.

くし形ルーバー２は、隣接する傾斜ルーバー１の間に設けてあり、上下方向に延びる複数本のくし材３を、見込方向に等間隔に並べて構成したものである。各くし材３は、平板状のものであって、見付方向に水平な向きであり、各くし材３の右端部の左右位置が、そのくし形ルーバー２の左側に位置する傾斜ルーバー１の右端部（室外側端部）及び右側に位置する傾斜ルーバー１の左端部（室内側端部）の左右位置と一致している。そして、各くし材３の見付幅が、最も室外側のものから順に漸増し、見込方向中間部から漸減している。また、くし形ルーバー２は、見込方向に延びて各くし材３を連結する桟材３３を備え、この桟材３３は上下に間隔を空けて複数設けてある。なお、各くし材３及び各桟材３３は、一体に成形されたものである。さらに、最も室内側のくし材３には、室内側に向けて突出する突条からなる室内側係合部３４を形成してあり、最も室外側のくし材３には、室外側に向けて突出する突条からなる室外側係合部３５を形成してあって、くし形ルーバー２の室内側係合部３４を、傾斜ルーバー１の室内側被係合部１４に係合させ、くし形ルーバー２の室外側係合部３５を、傾斜ルーバー１の室外側被係合部１５に係合させて、くし形ルーバー２を傾斜ルーバー１に固定してある。そして、各くし材３の室外側面３１は、平滑で、光の反射率が高く正反射成分の比率が大きな面であるのに対し、室内側面３２は、ローレット加工により細かい凹凸を形成してあり、光を拡散反射する面である。 The comb-shaped louver 2 is provided between adjacent inclined louvers 1, and is configured by arranging a plurality of comb members 3 extending in the vertical direction at equal intervals in the prospective direction. Each comb member 3 has a flat plate shape and is oriented horizontally in the finding direction, and the left and right positions of the right end portion of each comb member 3 are the inclined louvers 1 located on the left side of the comb-shaped louver 2. It coincides with the left and right positions of the right end (outdoor end) and the left end (indoor side end) of the inclined louver 1 located on the right side. Then, the found width of each comb material 3 gradually increases from the outermost one, and gradually decreases from the middle portion in the expected direction. Further, the comb-shaped louver 2 includes a crosspiece 33 extending in the prospective direction and connecting the comb members 3, and a plurality of the crosspieces 33 are provided at intervals in the vertical direction. It should be noted that each comb material 3 and each crosspiece 33 are integrally molded. Further, the comb material 3 on the most indoor side is formed with an indoor side engaging portion 34 composed of louvers protruding toward the indoor side, and the comb material 3 on the outermost outdoor side is formed toward the outdoor side. An outdoor side engaging portion 35 composed of protruding ridges is formed, and the indoor side engaging portion 34 of the comb-shaped louver 2 is engaged with the indoor side engaged portion 14 of the inclined louver 1 to form a comb shape. The outdoor engaging portion 35 of the louver 2 is engaged with the outdoor engaged portion 15 of the inclined louver 1, and the comb-shaped louver 2 is fixed to the inclined louver 1. The outdoor surface 31 of each comb material 3 is smooth, has a high light reflectance and a large proportion of specular reflection components, whereas the indoor side surface 32 has fine irregularities formed by knurling. , A surface that diffuses and reflects light.

ここで、くし形ルーバー２の各くし材３の見付幅について、その決定方法を詳述する。くし形ルーバー２は外部からの視線を遮るためのものであるが、くし材３の見付幅が長いほど、確実に視線を遮ることはできるが、採光量が少なくなってしまう。そこで、くし形ルーバー２の各くし材３は、視線を遮ることができる最低限の長さとすることが望ましい。図３に示すように、室外側面における傾斜ルーバー１同士の間隔をａ、室内側面における傾斜ルーバー１同士の間隔をｇ、傾斜ルーバー１の見付面１３の見付幅をｆ、放物線形状である室外側面１１の頂点Ｏから焦点Ｆまでの距離をａ／２とすると、放物線の方程式から、傾斜ルーバー１の見込幅ｄ＝√２×ａとなる。また、くし形ルーバー２のくし材３同士の間隔をｂ、くし材３の見込幅（厚さ）をｃとし、さらに、ルーバーの室内側面から、最も室内側のくし材３の室外側面までの距離をｋ、ルーバーの室外側面から、最も室外側のくし材３の室内側面までの距離をｊとする。そして、傾斜ルーバー１の室内側面１２の室内側端Ｐを通る視線（図３の一点鎖線）を考えると、くし形ルーバー２の最も室内側のくし材３から数えてｍ_１枚目のくし材３（見付幅ｘ_１）について、ｍ_１枚目のくし材３の左端とｍ_１＋１枚目のくし材３の右端を結んだ直線が見付方向となす角度をα_１、視線が見付方向となす角度をα_２として、次の式（１）が満たされれば、視線は遮られる。

図３より、式（１）は、次の式（２）で表される。

そして、式（２）を変形して、次の式（３）のとおり、ｘ_１の条件が求められる。

式（３）によれば、ｘ_１は、室内側のくし材３（ｍ_１が小さい）ほど長くなる。また、傾斜ルーバー１の室外側面１１の室外側端（頂点Ｏ）を通る視線（図３の二点鎖線）を考えると、くし形ルーバー２の最も室外側のくし材３を除外して（最も室外側のくし材３は、左端が左側の傾斜ルーバー１に連結されるので、長さは決まった値となる）、その次のくし材３から数えてｍ_２枚目のくし材３（見付幅ｘ_２）について、ｍ_２枚目のくし材３の左端とｍ_２−１枚目のくし材３の右端を結んだ直線が見付方向となす角度をβ_１、視線が見付方向となす角度をβ_２として、次の式（４）が満たされれば、視線は遮られる。

図３より、式（４）は、次の式（５）で表される。

そして、式（５）を変形して、次の式（６）のとおり、ｘ_２の条件が求められる。

式（６）によれば、ｘ_２は、室外側のくし材３（ｍ_２が小さい）ほど長くなる。なお、図３において、Ｐより右側の点及びＯより左側の点からは、くし形ルーバー２のくし材３同士がより重なって見えるので、Ｐ及びＯを通る視線が遮られていれば、それ以外の点を通る視線も遮られていることになる。また、Ｐを通る視線について、α_２が小さくなれば、視線はくし形ルーバー２がなくても、右側の傾斜ルーバー１により遮られるから、式（３）は、室外側の領域でのみ有効である。一方、Ｏを通る視線について、β_２が小さくなれば、視線はくし形ルーバー２がなくても、左側の傾斜ルーバー１により遮られるから、式（６）は、室内側の領域でのみ有効である。その結果、くし形ルーバー２のくし材３の見付幅は、最も室外側のものから順に漸増し（式（３）による）、見込方向中間部から漸減する（式（６）による）。 Here, a method for determining the found width of each comb material 3 of the comb-shaped louver 2 will be described in detail. The comb-shaped louver 2 is for blocking the line of sight from the outside. The longer the finding width of the comb material 3, the more reliably the line of sight can be blocked, but the amount of lighting is reduced. Therefore, it is desirable that each comb material 3 of the comb-shaped louver 2 has a minimum length that can block the line of sight. As shown in FIG. 3, the distance between the inclined louvers 1 on the outdoor side surface is a, the distance between the inclined louvers 1 on the indoor side surface is g, the found width of the found surface 13 of the inclined louver 1 is f, and the shape is a parabola. Assuming that the distance from the apex O of the outdoor surface 11 to the focal point F is a / 2, the expected width d = √2 × a of the inclined louver 1 is obtained from the parabolic equation. Further, the distance between the comb members 3 of the comb-shaped louver 2 is b, the expected width (thickness) of the comb member 3 is c, and further, from the indoor side surface of the louver to the outdoor side surface of the comb material 3 on the most indoor side. Let k be the distance, and j be the distance from the outdoor surface of the louver to the indoor side surface of the outermost comb material 3. The line of sight through the interior end P of the indoor side surface 12 of the inclined louvers 1 Given (one-dot chain line in FIG. 3), and most indoor m ₁ th counted from the comb member 3 of the comb member comb louver 2 About 3 (found wide x _1), the angle between the directing connecting it straight line viewed right end of the left and m ₁ +1 th comb member 3 of the comb member 3 of _{the first} sheet m alpha _1, seen gaze If the following equation (1) is satisfied, where the angle formed by the attachment direction is α _{2, the line of sight is blocked.}

From FIG. 3, the equation (1) is represented by the following equation (2).

Then, by modifying the equation (2), the following equation (3), the conditions of x ₁ is calculated.

According to the formula (3), x ₁ becomes longer as the comb material 3 (m _{1 is smaller) on the indoor side.} Further, considering the line of sight (two-point chain line in FIG. 3) passing through the outdoor end (apical point O) of the outdoor surface 11 of the inclined louver 1, the outermost comb material 3 of the comb-shaped louver 2 is excluded (most). comb member 3 of the outdoor side, since the left end is connected to the inclined louvers 1 left, a fixed value length), see the following as counted from the comb member 3 m ₂ sheet of comb member 3 ( for urging width x _2), the angle of beta ₁ which forms a directing connecting it straight line viewed right end of the m ₂ th comb member 3 of the left and m ₂ -1 th comb member _3, directing seen gaze If the following equation (4) is satisfied, _{where β 2 is set} as the angle between the two, the line of sight is blocked.

From FIG. 3, the equation (4) is represented by the following equation (5).

Then, by modifying the equation (5), the following equation (6), the condition of x ₂ is calculated.

According to the formula (6), x ₂ becomes longer as the comb material 3 (m _{2 is smaller) on the outdoor side.} In FIG. 3, from the point on the right side of P and the point on the left side of O, the comb members 3 of the comb-shaped louver 2 appear to overlap each other. The line of sight passing through points other than the above is also blocked. Further, regarding the line of sight passing through P, _{if α 2} becomes small, the line of sight is blocked by the inclined louver 1 on the right side even without the comb-shaped louver 2, so that the equation (3) is valid only in the outdoor region. .. On the other hand, with respect to the line of sight passing through O, _{if β 2} becomes small, the line of sight is blocked by the inclined louver 1 on the left side even without the comb-shaped louver 2, so that equation (6) is valid only in the indoor region. .. As a result, the found width of the comb material 3 of the comb-shaped louver 2 gradually increases from the outermost one (according to the equation (3)) and gradually decreases from the middle portion in the expected direction (according to the equation (6)).

このように構成した本発明のルーバーの第一実施形態によれば、上記のようにくし材３の見付幅を決定したくし形ルーバー２によって、図４（ａ）に示すように、傾斜ルーバー１同士の間を通した視線を遮り、室内外からの何れの方向の視線も遮りつつ、くし形ルーバー２のくし材３の見付幅を最低限の長さとすることで、最大限の採光量を確保できる。また、視線が通らないということは、室内に外部からの光が直接導光されることはなく、傾斜ルーバー１及び／又はくし形ルーバー２のくし材３で反射した光が導光される。そして特に、傾斜ルーバー１の室内側面１２及びくし形ルーバー２のくし材３の室内側面３２が、ローレット加工により細かい凹凸を形成した面となっており、図４（ｂ）に示すように、これらの面で光が拡散反射されるので、グレアを抑えることができる。さらに、傾斜ルーバー１の室外側面１１が放物線形状であることから、図５に示すように、放物線の焦点Ｆを通って入射する光が、入射角によらず、室外側面１１で見付方向（左右方向）に反射され、くし形ルーバー２を通り抜けて、隣接する傾斜ルーバー１の室内側面１２で拡散反射されるので、太陽光を効率よく室内に採り込める。 According to the first embodiment of the louver of the present invention configured in this way, as shown in FIG. 4A, the inclined louver is formed by the comb-shaped louver 2 in which the found width of the comb material 3 is determined as described above. Maximum lighting is achieved by blocking the line of sight that passes between the two and blocking the line of sight from inside and outside in any direction, while minimizing the finding width of the comb material 3 of the comb-shaped louver 2. The amount can be secured. Further, the fact that the line of sight does not pass means that the light from the outside is not directly guided into the room, but the light reflected by the comb material 3 of the inclined louver 1 and / or the comb-shaped louver 2 is guided. In particular, the indoor side surface 12 of the inclined louver 1 and the indoor side surface 32 of the comb material 3 of the comb-shaped louver 2 are surfaces on which fine irregularities are formed by knurling, and as shown in FIG. 4 (b), these are Since the light is diffusely reflected on the surface of the surface, glare can be suppressed. Further, since the outdoor surface 11 of the inclined louver 1 has a parabolic shape, as shown in FIG. 5, the light incident through the focal point F of the parabola is found on the outdoor surface 11 regardless of the angle of incidence. It is reflected in the left-right direction), passes through the comb-shaped louver 2, and is diffusely reflected by the indoor side surface 12 of the adjacent inclined louver 1, so that sunlight can be efficiently taken into the room.

また、図６に示すのは、本発明のルーバーの第二実施形態である。第二実施形態は、第一実施形態と同じ形状の傾斜ルーバー１及びくし形ルーバー２を枠体１０の内周側に設けたものであるが、傾斜ルーバー１及びくし形ルーバー２のくし材３が、上下方向に対して傾斜して延びる向きに設けてある点が、第一実施形態とは異なっている。このように傾斜ルーバー１及びくし形ルーバー２を傾斜させることで、室外側の上方から射し込む太陽光（図中の実線矢印）が上方に向けて反射され（図中の破線矢印）、天井面に導光されるので、室内を明るくすることができる。なお、より効率的に太陽光を反射するために、ルーバーを設置する窓の方角に応じて、傾斜ルーバー１及びくし形ルーバー２の傾斜方向を変えてもよい。 Further, FIG. 6 shows a second embodiment of the louver of the present invention. In the second embodiment, the inclined louver 1 and the comb-shaped louver 2 having the same shape as those in the first embodiment are provided on the inner peripheral side of the frame 10, but the comb material 3 of the inclined louver 1 and the comb-shaped louver 2 is provided. However, it is different from the first embodiment in that it is provided so as to be inclined and extended with respect to the vertical direction. By inclining the inclined louver 1 and the comb-shaped louver 2 in this way, the sunlight shining from above the outdoor side (solid line arrow in the figure) is reflected upward (broken arrow in the figure) and is reflected on the ceiling surface. Since the light is guided, the room can be brightened. In addition, in order to reflect sunlight more efficiently, the inclination directions of the inclined louver 1 and the comb-shaped louver 2 may be changed according to the direction of the window in which the louver is installed.

次に、図７に基づき、本発明のルーバーの第三実施形態について説明する。第三実施形態は、矩形の枠体１０を有し、枠体１０の内周側に、傾斜ルーバー１と、拡散透過パネル４を備えている。このうち、枠体１０と傾斜ルーバー１は、第一実施形態と同じものである。 Next, a third embodiment of the louver of the present invention will be described with reference to FIG. 7. The third embodiment has a rectangular frame body 10, and includes an inclined louver 1 and a diffusion transmission panel 4 on the inner peripheral side of the frame body 10. Of these, the frame body 10 and the inclined louver 1 are the same as those in the first embodiment.

拡散透過パネル４は、隣接する傾斜ルーバー１の間に設けてあり、上下方向に延び見込方向に水平な向きの乳白色の樹脂製平板からなり、入射した光を、拡散して透過させるものである。そして拡散透過パネル４の左右位置は、拡散透過パネル４の左側の傾斜ルーバー１の右端部（室外側端部）と右側の傾斜ルーバー１の左端部（室内側端部）の左右位置と一致している。また、拡散透過パネル４の室内側端部と室外側端部には、それぞれ略Ｌ字形の室内側係合部４１と室外側係合部４２を形成してあって、拡散透過パネル４の室内側係合部４１を、傾斜ルーバー１の室内側被係合部１４に係合させ、拡散透過パネル４の室外側係合部４２を、傾斜ルーバー１の室外側被係合部１５に係合させて、拡散透過パネル４を傾斜ルーバー１に固定してある。 The diffusion transmission panel 4 is provided between adjacent inclined louvers 1 and is made of a milky white resin flat plate extending in the vertical direction and horizontally in the prospective direction, and diffuses and transmits incident light. .. The left and right positions of the diffusion transmission panel 4 coincide with the left and right positions of the right end portion (outdoor end portion) of the inclined louver 1 on the left side of the diffusion transmission panel 4 and the left end portion (indoor side end portion) of the inclined louver 1 on the right side. ing. Further, a substantially L-shaped indoor side engaging portion 41 and an outdoor side engaging portion 42 are formed at the indoor side end portion and the outdoor side end portion of the diffusion transmission panel 4, respectively, and the chamber of the diffusion transmission panel 4 is formed. The inner engaging portion 41 is engaged with the indoor side engaged portion 14 of the inclined louver 1, and the outdoor engaging portion 42 of the diffusion transmission panel 4 is engaged with the outdoor engaged portion 15 of the inclined louver 1. The diffusion transmission panel 4 is fixed to the inclined louver 1.

このように構成した本発明のルーバーの第三実施形態によれば、傾斜ルーバー１同士の隙間が、全て乳白色の拡散透過パネル４により塞がれているので、室内外からの何れの方向の視線も遮りつつ、採光を確保できる。また、外部からの光は、全て拡散透過パネル４を通ることで拡散され、そのまま室内へ入射するか、傾斜ルーバー１の室内側面１２でさらに拡散反射されて室内へ入射するので、グレアを抑えることができる。 According to the third embodiment of the louver of the present invention configured in this way, since all the gaps between the inclined louvers 1 are closed by the milky white diffusion / transmission panel 4, the line of sight in any direction from indoors and outdoors. It is possible to secure the lighting while blocking the light. Further, all the light from the outside is diffused by passing through the diffuse transmission panel 4 and is incident into the room as it is, or is further diffusely reflected by the indoor side surface 12 of the inclined louver 1 and is incident into the room, so that glare is suppressed. Can be done.

また、第四実施形態として、第三実施形態と同じ形状の傾斜ルーバー１及び拡散透過パネル４を、第二実施形態と同じように、上下方向に対して傾斜して延びる向きに設けてもよい。このように傾斜ルーバー１及び拡散透過パネル４を傾斜させることで、第二実施形態と同様に、室外側の上方から射し込む太陽光が上方に向けて反射され、天井面に導光されるので、室内を明るくすることができる。なお、より効率的に太陽光を反射するために、ルーバーを設置する窓の方角に応じて、傾斜ルーバー１及び拡散透過パネル４の傾斜方向を変えてもよい。 Further, as the fourth embodiment, the inclined louver 1 and the diffusion transmission panel 4 having the same shape as the third embodiment may be provided in a direction in which the inclined louver 1 and the diffusion transmission panel 4 have the same shape as the third embodiment are inclined and extended in the vertical direction. .. By inclining the inclined louver 1 and the diffusion transmission panel 4 in this way, as in the second embodiment, the sunlight shining from above the outdoor side is reflected upward and guided to the ceiling surface. The room can be brightened. In addition, in order to reflect sunlight more efficiently, the tilting direction of the tilting louver 1 and the diffusion transmission panel 4 may be changed according to the direction of the window in which the louver is installed.

本発明は、上記の実施形態に限定されない。たとえば、傾斜ルーバー、くし形ルーバー及び拡散透過パネルの形状は、上記の要件を満たすものであれば、どのようなものであってもよい。傾斜ルーバーの室外側面は放物線形状であることが望ましいが、その焦点の位置は、傾斜ルーバー同士の隙間の左右方向中央に限られず、ルーバーの室外側面上のどこにあってもよい。また、くし形ルーバーのくし材同士の間隔が一定でなくてもよい。そして、傾斜ルーバー及び／又はくし形ルーバーのくし材の室内側面は、拡散反射面であることが望ましいが、この拡散反射面とは、少なくとも室外側面より拡散反射成分の比率が大きい面であり、ローレット加工以外の表面加工、塗装、別部材による被覆など、どのように形成されるものであってもよい。さらに、拡散透過パネルは、光を通しつつ直進を妨げるものであればよく、半透明の樹脂板・ガラス板や、すりガラスのように表面に凹凸を形成したもの、または透明板の表面に乳白色や半透明のフィルムを貼ったものなど、どのようなものであってもよい。 The present invention is not limited to the above embodiments. For example, the shape of the inclined louver, the comb-shaped louver, and the diffusion transmission panel may be any shape as long as they satisfy the above requirements. The outdoor surface of the inclined louver is preferably parabolic, but the position of the focal point is not limited to the center of the gap between the inclined louvers in the left-right direction, and may be anywhere on the outdoor surface of the louver. Further, the distance between the comb members of the comb-shaped louver does not have to be constant. The indoor side surface of the comb material of the inclined louver and / or the comb-shaped louver is preferably a diffuse reflection surface, and the diffuse reflection surface is at least a surface having a larger ratio of the diffuse reflection component than the outdoor surface. It may be formed in any way such as surface processing other than louver processing, painting, and coating with another member. Further, the diffusion / transmission panel may be any one that allows light to pass through and hinders straight-ahead travel, and may be a translucent resin plate / glass plate, a frosted glass having irregularities on the surface, or a milky white surface of the transparent plate. It may be anything, such as one with a translucent film attached.
