しかしながら、上述のような従来の照明器具では、異なった色の光を隣接する部位から照射することは不可能である。このような要求に応える照明器具としては、例えば、筐体の内部を仕切り板により複数に仕切り、各仕切り空間内に光源を設けるとともに、各仕切り空間の開口に所望の色の光透過性部材を配設した照明器具が考えられる。しかし、このような照明器具では、照射光の色が固定されてしまい、例えば、隣接する部位からの照射光の色を所望の時間経過毎に適宜変えることは不可能である。   However, in the conventional lighting fixture as described above, it is impossible to irradiate light of different colors from adjacent parts. As a lighting fixture that meets such demands, for example, the interior of the housing is partitioned into a plurality of partitions, a light source is provided in each partition space, and a light transmissive member of a desired color is provided in the opening of each partition space. Arranged lighting fixtures are conceivable. However, in such a lighting fixture, the color of the irradiation light is fixed, and for example, it is impossible to appropriately change the color of the irradiation light from an adjacent part for every desired time.

これに対応するために、仕切り板を用いて内部を複数に仕切った筐体の各仕切り空間毎に複数色の光源を配設し、各仕切り空間の開口全体を覆うように光透過性部材を載置した照明器具が考えられる。このような照明器具では、各仕切り空間毎に光源の発光色を変えることにより、隣接する部位からの照射光の色を適宜変更することができる。しかし、このような照明器具は、仕切り板による影が、例えば、碁盤目のように認識されてしまい、装飾性等を低下させるという問題があった。また、仕切り板の影が認識されないように、仕切り板を低くする(光透過性部材から仕切り板の先端を離間させる)ことも考えられるが、このような構造では、隣接する部位の発光色が異なる場合、光の混合が生じてしまい、境界線の鮮明な色表示が行えないという問題があった。   In order to cope with this, a plurality of color light sources are arranged in each partition space of the housing divided into a plurality of parts by using a partition plate, and a light transmissive member is provided so as to cover the entire opening of each partition space. A mounted luminaire can be considered. In such a lighting fixture, the color of the irradiation light from an adjacent site | part can be suitably changed by changing the luminescent color of a light source for every partition space. However, such a lighting fixture has a problem in that the shadow of the partition plate is recognized as, for example, a grid pattern, and the decorativeness is deteriorated. In addition, it is conceivable that the partition plate is lowered (the tip of the partition plate is separated from the light transmissive member) so that the shadow of the partition plate is not recognized. If they are different from each other, there is a problem in that light mixing occurs, and a clear color display of the boundary line cannot be performed.

本発明は、上記のような実情に鑑みてなされたものであり、境界線の鮮明さを有しながら隣接する部位からの異なる色による照射を可能とする照明器具を提供することを目的とする。   This invention is made | formed in view of the above situations, and it aims at providing the lighting fixture which enables irradiation by the different color from an adjacent site | part, having the clearness of a boundary line. .

このような目的を達成するために、本発明の照明器具は、開口面を有するケース体と、該開口面に複数の開口部を形成するように前記ケース体の内部を仕切る仕切り板と、各仕切り空間内に配設された光源と、各開口部を閉塞する複数の透光蓋体とを備え、前記開口部を形成する前記仕切り板の上端部において隣接する透光蓋体どうしが当接し、前記透光蓋体は透明基板の表面に白色部材を有する積層体であり、かつ、少なくとも隣接する透光蓋体と当接する面に白色膜または反射膜を有するものであるような構成とした。   In order to achieve such an object, a lighting fixture of the present invention includes a case body having an opening surface, a partition plate that partitions the inside of the case body so as to form a plurality of openings in the opening surface, A light source disposed in the partition space and a plurality of light-transmitting lids that close each opening, and adjacent light-transmitting lids abut at the upper end of the partition plate that forms the opening. The translucent cover is a laminated body having a white member on the surface of the transparent substrate, and at least a white film or a reflective film is provided on the surface in contact with the adjacent translucent cover. .

As a preferred aspect of the present invention, the transparent substrate includes a notch for engaging with the opening, and the thickness of the transparent substrate positioned at the upper end of the partition plate is 2 mm or more. It was.

このような本発明では、各仕切り空間毎に光源から透光蓋体に照射された光は、透光蓋体を構成する透明基板および白色部材を透過して、光源の色に応じた光が透光蓋体から照射され、このとき、透明基板内を隣接する透光蓋体方向に進んだ光は、白色膜または反射膜によって隣接する透光蓋体内への侵入が抑制され、異なる光源からの光の混合が防止されることとなり、また、隣接する透光蓋体の境界に位置する仕切り板の上端部と、透光蓋体を構成する白色部材との間には、透明基板が介在して間隙が確保されているので、仕切り板の上端部の影が白色部材に鮮明に映ることが抑制され、さらに、仕切り板の上端部に位置する白色膜または反射膜により反射された光が白色部材に到達し、これにより、透光蓋体の境界線で色が鮮明に異なった光の照射が可能になるという効果が奏される。   In the present invention, the light emitted from the light source to the translucent lid for each partition space is transmitted through the transparent substrate and the white member constituting the translucent lid, and the light according to the color of the light source is emitted. At this time, the light radiated from the transparent cover body and traveling in the direction of the adjacent transparent cover body in the transparent substrate is prevented from entering into the adjacent transparent cover body by the white film or the reflective film, and from different light sources. Light mixture is prevented, and a transparent substrate is interposed between the upper end of the partition plate located at the boundary between adjacent light-transmitting lids and the white member constituting the light-transmitting lid. Since the gap is secured, the shadow of the upper end portion of the partition plate is prevented from being clearly reflected on the white member, and the light reflected by the white film or the reflective film located on the upper end portion of the partition plate is further suppressed. The white member is reached, so that the color is clearly different at the boundary of the transparent lid. Effect that irradiation of light becomes possible and is exhibited.

以下、本発明の実施の形態について図面を参照して説明する。
図1は本発明の照明器具の一実施形態を示す斜視図であり、図2は照明器具を構成するケース体の斜視図であり、図3は図1に示される照明器具のA−A線における断面図である。図1〜図3において、本発明の照明器具1は、ケース体2と、このケース体2の開口面に配設された複数の透光蓋体11を備えている。
照明器具1を構成するケース体2は、開口面3を備え、仕切り板4によって内部が仕切られている。これにより2個の仕切り空間5a,5bが形成され、開口面3には2個の開口部6a,6bが形成されている。また、各仕切り空間5a,5b内には光源8が配設されている。
Embodiments of the present invention will be described below with reference to the drawings.
1 is a perspective view showing an embodiment of a lighting fixture of the present invention, FIG. 2 is a perspective view of a case body constituting the lighting fixture, and FIG. 3 is a line AA of the lighting fixture shown in FIG. FIG. 1 to 3, the luminaire 1 of the present invention includes a case body 2 and a plurality of light-transmitting lid bodies 11 disposed on the opening surface of the case body 2.
The case body 2 constituting the lighting apparatus 1 includes an opening surface 3, and the inside is partitioned by a partition plate 4. As a result, two partition spaces 5 a and 5 b are formed, and two opening portions 6 a and 6 b are formed in the opening surface 3. A light source 8 is disposed in each of the partition spaces 5a and 5b.

ケース体2は、材質に特に制限はなく、例えば、金属、ガラス、樹脂、カーボン繊維等の材料、あるいは、これらの任意の組み合わせからなる複合材料等を用いて作製したものを使用することができる。図示例では、ケース体2は1つの開口面3を備えるものであるが、これに限定されるものではなく、例えば、透光蓋体11が配設される面と反対側にも開口面を備えるものであってもよい。
仕切り板4は、ケース体2の内部を複数に仕切ることにより開口部6a、6bを形成するとともに、隣接する仕切り空間での光の漏れを防止することを目的としている。このような仕切り板4は、ケース体2と同時成形されたもの、別体の仕切り板材をケース2内部に配設したものいずれであってもよい。後者の場合、仕切り板4の材質は、ケース体2の材質と同じであっても、異なるものであってもよい。
The case body 2 is not particularly limited in material, and for example, a material produced using a material such as metal, glass, resin, carbon fiber, or a composite material composed of any combination thereof can be used. . In the illustrated example, the case body 2 is provided with one opening surface 3. However, the present invention is not limited to this. For example, an opening surface is provided on the side opposite to the surface on which the translucent lid 11 is disposed. It may be provided.
The partition plate 4 is intended to form the openings 6a and 6b by partitioning the inside of the case body 2 into a plurality, and to prevent light leakage in adjacent partition spaces. Such a partition plate 4 may be either formed simultaneously with the case body 2 or a separate partition plate material disposed inside the case 2. In the latter case, the material of the partition plate 4 may be the same as or different from the material of the case body 2.

ケース体2の各仕切り空間5a,5b内に配設された光源8は、照明器具1の使用目的に応じて適宜選択することできる。例えば、光源8として、電球、放電管、および発光ダイオード素子のいずれかを使用することができる。また、光源8は、複数色の光源からなり、かつ、所望の色の光源を発光させることができるように、例えば、1つの仕切り空間において、赤色、青色、緑色の3種の発光を任意に選択できるようにしてもよい。   The light source 8 disposed in each of the partition spaces 5 a and 5 b of the case body 2 can be appropriately selected according to the purpose of use of the lighting fixture 1. For example, any one of a light bulb, a discharge tube, and a light-emitting diode element can be used as the light source 8. Further, the light source 8 is composed of light sources of a plurality of colors, and, for example, can arbitrarily emit three types of light emission of red, blue, and green in one partition space so that a light source of a desired color can be emitted. You may make it selectable.

また、照明器具1を構成する透光蓋体11は、各開口部6a,6bを閉塞するように配設されており、仕切り板4の上端部4aにおいて、隣接する透光蓋体11,11どうしが当接している。図4は、透光蓋体11の拡大断面図であり、図4に示されるように、透光蓋体11は、透明基板12と、この透明基板12の表面(照明器具11の照射面側)に積層された白色部材13とを備えた積層体である。この透光蓋体11は、隣接する透光蓋体と当接する1つの側面と、他の3つの側面に白色膜14を備えている。また、透光蓋体11は、透明基板12の裏面側の周辺部に切欠き部12aを備えている。このため、この切欠き部12aを開口部6a,6bを構成するケース体2と仕切り板4に係止するようにして、透光蓋体11は開口部6a,6bに嵌着されている。   Moreover, the transparent cover 11 which comprises the lighting fixture 1 is arrange | positioned so that each opening part 6a, 6b may be obstruct | occluded, and in the upper end part 4a of the partition plate 4, the adjacent transparent cover 11, 11 is provided. The two are in contact. FIG. 4 is an enlarged cross-sectional view of the translucent lid 11. As shown in FIG. 4, the translucent lid 11 includes the transparent substrate 12 and the surface of the transparent substrate 12 (on the irradiation surface side of the lighting fixture 11). And a white member 13 laminated on the laminated body. This translucent lid 11 is provided with a white film 14 on one side contacting the adjacent translucent lid and the other three side surfaces. The translucent lid 11 includes a notch 12 a in the peripheral portion on the back side of the transparent substrate 12. For this reason, the translucent cover 11 is fitted to the openings 6a and 6b so that the notch 12a is locked to the case body 2 and the partition plate 4 constituting the openings 6a and 6b.

透光蓋体11を構成する透明基板12は、例えば、アクリル樹脂等の透明樹脂基板、ガラス基板等を使用することができる。このような透明基板12の仕切り板4の上端部4aに位置する厚みT(図4参照)は、2mm以上、好ましくは4mm以上とすることができる。この厚みTが2mm未満であると、仕切り板4の上端部4aの影が白色部材13に映り易くなり好ましくない。尚、厚みTの上限は特になく、使用目的に応じて設定することができ、例えば、床面に本発明の照明器具を配設して使用する場合、人間の体重を支えるための強度を考慮して厚みTを大きく設定することができる。   For example, a transparent resin substrate such as an acrylic resin, a glass substrate, or the like can be used as the transparent substrate 12 constituting the light-transmitting lid 11. The thickness T (see FIG. 4) located at the upper end 4a of the partition plate 4 of the transparent substrate 12 can be 2 mm or more, preferably 4 mm or more. If the thickness T is less than 2 mm, the shadow of the upper end portion 4a of the partition plate 4 is easily reflected on the white member 13, which is not preferable. The upper limit of the thickness T is not particularly limited and can be set according to the purpose of use. For example, when the lighting apparatus of the present invention is used on the floor surface, the strength for supporting the human weight is considered. Thus, the thickness T can be set large.

透光蓋体11を構成する白色部材13は、例えば、アクリル樹脂等の樹脂材料からなる白色、乳白色等の光散乱が可能な板材、あるいはシートを使用することができる。このような白色部材13の厚みtは、例えば、0.1〜10mm、好ましくは2〜8mm程度で設定することができる。白色部材13の厚みtが0.1mm未満であると、仕切り板4の上端部4aの影が白色部材13に映り易くなり、また、厚みtが10mmを超えると、白色部材13を透過する光量が少なくなり、十分な明るさが得られない場合がある。したがって、白色部材13の厚みは、光源の光度、白色部材13の材質等を考慮して適宜設定することができる。また、白色部材13は、表面(透明基板12と反対側の面)に、例えば、意匠上の凹凸や種々の形状を有し、厚みが均一でないものであってもよい。尚、透明基板12と白色部材13との接着は、従来公知の接着剤を用いて行うことができる。   As the white member 13 constituting the translucent lid 11, for example, a white or milky white plate material or sheet made of a resin material such as acrylic resin can be used. The thickness t of such a white member 13 can be set to, for example, about 0.1 to 10 mm, preferably about 2 to 8 mm. When the thickness t of the white member 13 is less than 0.1 mm, the shadow of the upper end portion 4a of the partition plate 4 is easily reflected on the white member 13, and when the thickness t exceeds 10 mm, the amount of light transmitted through the white member 13 In some cases, sufficient brightness cannot be obtained. Therefore, the thickness of the white member 13 can be appropriately set in consideration of the light intensity of the light source, the material of the white member 13, and the like. Further, the white member 13 may have, for example, design irregularities and various shapes on the surface (the surface opposite to the transparent substrate 12), and the thickness may not be uniform. The transparent substrate 12 and the white member 13 can be bonded using a conventionally known adhesive.

透光蓋体11の側面に設けられている白色膜14は、透明基板12内を進んできた光が隣接する別の透光蓋体11に侵入することを阻止するとともに、この光を反射して、仕切り板4の上端部4aによる影を打ち消すことを目的としたものである。したがって、白色膜14は、必ずしも白色である必要はなく、光源8で発光される光に対して50%以上の反射率を示すものであればよい。しかし、光源8で発光される光の色が種々変化する場合を考慮すると、可視光の全波長域において50%以上の反射率を示す白色乃至乳白色の膜であることが好ましい。光源8で発光される光に対する白色膜14の反射率が50%未満である場合、仕切り板4の上端部4aによる影を十分に打ち消すことができず、隣接する透光蓋体11の境界部位において黒色線が認識されてしまい好ましくない。勿論、白色膜14の代わりに、黒色膜を使用した場合には、透明基板12内を進んできた光が隣接する別の透光蓋体11に侵入することは阻止できるが、黒色膜自体が隣接する透光蓋体11の境界部位において黒色線として認識され好ましくない。   The white film 14 provided on the side surface of the translucent lid 11 prevents light that has traveled through the transparent substrate 12 from entering another adjacent translucent lid 11 and reflects this light. The purpose is to cancel the shadow caused by the upper end 4a of the partition plate 4. Therefore, the white film 14 does not necessarily need to be white and may be any film that exhibits a reflectance of 50% or more with respect to the light emitted from the light source 8. However, in consideration of various changes in the color of light emitted from the light source 8, a white or milky white film exhibiting a reflectance of 50% or more in the entire wavelength range of visible light is preferable. When the reflectance of the white film 14 with respect to the light emitted from the light source 8 is less than 50%, the shadow caused by the upper end portion 4a of the partition plate 4 cannot be sufficiently canceled out, and the boundary portion between the adjacent translucent lids 11 In this case, a black line is recognized, which is not preferable. Of course, when a black film is used instead of the white film 14, it is possible to prevent the light that has traveled through the transparent substrate 12 from entering the adjacent transparent cover 11, but the black film itself This is not preferable because it is recognized as a black line at the boundary portion between the adjacent translucent lids 11.

上記のような白色膜14は、例えば、白色塗料、乳白色塗料、灰白色塗料等を塗布して形成したもの、白色樹脂フィルム、乳白色樹脂フィルム、灰白色樹脂フィルム等を貼着したもの等、いずれであってもよい。この白色膜14は、図示例では、切欠き部12aには設けられていないが、図5に示すように、切欠き部12aにも設けられたものであってもよい。また、本発明では、白色膜14の代わりに、反射膜を設けてもよい。この反射膜は、上述の白色膜と同様の作用をなすことを目的としたものであり、例えば、アルミニウム箔等の金属箔を貼着したもの、金属粉含有塗料を塗布したもの等であってよい。   The white film 14 as described above is, for example, one formed by applying a white paint, milky white paint, grayish white paint, or the like, or a white resin film, a milky white resin film, a gray white resin film, or the like. May be. The white film 14 is not provided in the notch 12a in the illustrated example, but may be provided in the notch 12a as shown in FIG. In the present invention, a reflective film may be provided instead of the white film 14. This reflective film is intended to perform the same action as the above-described white film, and is, for example, a metal foil such as an aluminum foil or a metal powder-containing paint applied. Good.

このような透光蓋体11は、切欠き部12aの幅Wを仕切り板4の厚みの半分に設定することにより、開口部6a,6bに嵌着された状態で、仕切り板4の上端部4aにおいて隣接する透光蓋体11どうしが当接することとなる。また、必要に応じて、開口部6a,6bをなすケース体2と仕切り板4の端部に接着剤を用いて固着してもよい。
尚、本発明では、透光蓋体11は切欠き部12aを備えていないものであってもよい。この場合、図6に示すように、仕切り板4の上端部4aにおいて隣接する透光蓋体11,11どうしが当接するように載置し、開口部6a,6bをなすケース体2と仕切り板4の端部に、接着剤を用いて固着することができる。
Such a translucent lid 11 is configured such that the upper end portion of the partition plate 4 is fitted to the openings 6a and 6b by setting the width W of the notch 12a to half the thickness of the partition plate 4. In 4a, the adjacent translucent cover bodies 11 will contact | abut. Moreover, you may adhere to the case body 2 which makes the opening parts 6a and 6b, and the edge part of the partition plate 4 using an adhesive agent as needed.
In the present invention, the translucent cover 11 may not have the notch 12a. In this case, as shown in FIG. 6, the case body 2 and the partition plate which are placed so that the adjacent light-transmitting lid bodies 11 and 11 are in contact with each other at the upper end portion 4 a of the partition plate 4 and form the openings 6 a and 6 b. It can be fixed to the end of 4 using an adhesive.

このような本発明の照明器具1では、各仕切り空間5a,5b毎に光源8から透光蓋体11に照射された光は、各透光蓋体11を構成する透明基板12および白色部材13を透過して、光源8の発光色に応じた光が各透光蓋体11から外部に照射される。そして、例えば、仕切り空間5aにおいて光源8から照射され、仕切り空間5aに配設された透光蓋体11の透明基板12内を、隣接する仕切り空間5b方向に透過した光は、透光蓋体11の白色膜14により遮断される。また、隣接する透光蓋体11,11の境界に位置する仕切り板4の上端部4aと、透光蓋体11を構成する白色部材13との間には、透明基板12が介在することにより空隙が存在するので、仕切り板4の上端部4aの影が白色部材に鮮明に映ることがなく、さらに、仕切り板4の上端部4aに位置する白色膜14により反射された光が、仕切り板4の上端部4aの影を打ち消すことになる。これにより、異なる光源からの光が透光蓋体11において混合することが防止され、透光蓋体11の境界線で色が鮮明に異なる光の照射が可能になる。   In such a lighting fixture 1 of the present invention, the light emitted from the light source 8 to the light-transmitting lid body 11 for each of the partition spaces 5a and 5b is transmitted through the transparent substrate 12 and the white member 13 constituting each light-transmitting lid body 11. , And the light corresponding to the emission color of the light source 8 is irradiated to the outside from each light-transmitting lid body 11. Then, for example, light irradiated from the light source 8 in the partition space 5a and transmitted through the transparent substrate 12 of the light-transmitting lid body 11 disposed in the partition space 5a in the direction of the adjacent partition space 5b is transmitted through the light-transmitting lid body. 11 white film 14. Further, the transparent substrate 12 is interposed between the upper end portion 4a of the partition plate 4 located at the boundary between the adjacent light-transmitting lid bodies 11 and 11 and the white member 13 constituting the light-transmitting lid body 11. Since there is an air gap, the shadow of the upper end portion 4a of the partition plate 4 is not clearly reflected on the white member, and the light reflected by the white film 14 positioned on the upper end portion 4a of the partition plate 4 is further separated. 4 cancels the shadow of the upper end 4a. Thereby, it is possible to prevent light from different light sources from being mixed in the translucent lid 11, and it is possible to irradiate light with clearly different colors at the boundary line of the translucent lid 11.
