この考案は、電磁シールドルームの天井に埋め込まれる箱形の照明器具に関す るものである。 The present invention relates to a box-shaped lighting fixture embedded in the ceiling of an electromagnetically shielded room.
【０００２】[0002]
図７に従来の照明器具の一例の断面図を示し、図８および図９に図７の要部の 拡大断面図を示す。この照明器具は、下面を開放して内部に例えば直管形の蛍光 ランプ１が配置された箱形の器具本体２の開口に化粧枠３を取り付けている。 器具本体２は、側板２ａが天板２ｂの周縁に重なるように側板２ａの上部を直 角に折り曲げた構造としている。 FIG. 7 shows a cross-sectional view of an example of a conventional lighting fixture, and FIGS. 8 and 9 show enlarged cross-sectional views of the main part of FIG. In this lighting fixture, a decorative frame 3 is attached to an opening of a box-shaped fixture main body 2 in which a lower surface of the lighting fixture is opened and, for example, a straight tube fluorescent lamp 1 is arranged therein. The instrument main body 2 has a structure in which the upper portion of the side plate 2a is bent at a right angle so that the side plate 2a overlaps the peripheral edge of the top plate 2b.
【０００３】 化粧枠３は、上端縁に器具本体２の開口端縁に対向する本体受け用水平片３ａ を設け、この本体受け用水平片３ａに器具本体２の外周側に立ち上がる立ち上が り片３ｂを設けている。化粧枠３には、乳白色のパネル５が取り付けられている 。 そして、器具本体２の開口縁と化粧枠３の立ち上がり片３ｂとをビス４で固定 することにより、器具本体２に化粧枠３を固定している。The decorative frame 3 is provided with a horizontal piece 3a for receiving the main body which faces the opening edge of the main body 2 of the appliance at the upper edge thereof, and the horizontal piece 3a for receiving the main body stands upright on the outer peripheral side of the main body 2 of the appliance. The piece 3b is provided. A milky white panel 5 is attached to the decorative frame 3. Then, the decorative frame 3 is fixed to the device body 2 by fixing the opening edge of the device body 2 and the rising piece 3b of the decorative frame 3 with screws 4.
【０００４】[0004]
図７ないし図９に示した照明器具は、器具本体２の開口に化粧枠３を取り付け た場合にも、器具本体２と化粧枠３との間に隙間が残る。また、器具本体２を形 成する際に、側板２ａを折り曲げて天板２ｂの周縁に重ね合わせたとしても、側 板２ａと天板２ｂとの間に隙間が残ることもある。 In the lighting device shown in FIGS. 7 to 9, even when the decorative frame 3 is attached to the opening of the device main body 2, a gap remains between the device main body 2 and the decorative frame 3. Further, even when the side plate 2a is bent and overlapped with the peripheral edge of the top plate 2b when the instrument body 2 is formed, a gap may remain between the side plate 2a and the top plate 2b.
【０００５】 一方、電磁シールドルームは、室外の電磁波が室内に入らないように、完全に 電磁波を遮断するであるが、このような電磁シールドルームの天井に照明器具を 埋め込む場合に、電磁シールドした天井に開口を設けることになるので、その開 口部分に取り付ける照明器具は、器具本体および化粧枠等を金属製として電磁シ ールド機能を備えさせることが要求される。On the other hand, the electromagnetically shielded room completely blocks the electromagnetic waves so that the electromagnetic waves outside the room do not enter the room. However, when the lighting equipment is embedded in the ceiling of such an electromagnetically shielded room, the electromagnetic shield is provided. Since an opening will be provided in the ceiling, the lighting fixture attached to the opening is required to have an electromagnetic shield function with the fixture body and decorative frame made of metal.
【０００６】 電磁シールドルームの天井に埋め込む照明器具として、図７ないし図９に示し たような照明器具を使用した場合、上記照明器具には前記したような隙間があり 、この隙間の方向は電磁シールドルームの斜め上方から到来する電磁波の伝搬方 向に対して直交する状態よりも平行に近い状態にあったり、また器具本体２を構 成する板材の重ね合わせ代が少なかったりして、図８および図９において、矢符 Ａ1 ，Ｂ1 で示すように器具本体２および化粧枠３の外部から到来した電磁波が 、隙間を通して矢符Ａ2 ，Ｂ2 で示すように器具本体２の内部に漏れ込み、結果 として照明器具を設置した電磁シールドルーム内に電磁波が侵入し、電磁シール ドルームにおける電磁シールド機能を損なうおそれがあった。When a lighting fixture as shown in FIGS. 7 to 9 is used as a lighting fixture to be embedded in the ceiling of an electromagnetically shielded room, the above-mentioned lighting fixture has a gap as described above, and the direction of this gap is electromagnetic. As it is closer to being parallel than the direction orthogonal to the propagation direction of electromagnetic waves coming from diagonally above the shield room, and there is little overlapping margin of the plate materials that make up the instrument body 2, And in FIG. 9, electromagnetic waves arriving from the outside of the device body 2 and the decorative frame 3 as indicated by arrows A 1 and B 1 enter the inside of the device body 2 through the gap as shown by arrows A 2 and B 2. There was a risk of leakage, and as a result, electromagnetic waves would enter the electromagnetic shield room where the lighting equipment was installed, impairing the electromagnetic shield function in the electromagnetic shield room.
【０００７】 したがって、この考案の目的は、電磁シールドルームにおける電磁シールド機 能を損なうことが少ない照明器具を提供することである。[0007] Therefore, an object of the present invention is to provide a lighting fixture that does not impair the electromagnetic shield function in an electromagnetic shield room.
【０００８】[0008]
この考案の照明器具は、下面を開放して内部にランプが配置される箱形の器具 本体の開口に化粧枠を取り付けている。化粧枠は、上端縁に器具本体の開口端縁 に対向する本体受け用水平片を設け、この本体受け用水平片に器具本体の内周側 に立ち上がる立ち上がり片を設けている。 The lighting device of this invention has a decorative frame attached to the opening of the box-shaped device body with the lower surface opened and the lamp arranged inside. The decorative frame is provided with a horizontal piece for receiving the main body, which is opposed to the opening edge of the main body of the equipment at the upper edge, and a rising piece which stands up on the inner peripheral side of the main body of the main body.
【０００９】[0009]
この考案の構成によれば、器具本体の開口端縁に対向するように化粧枠の上端 縁に設けた本体受け用水平片に器具本体の内周側に立ち上がる立ち上がり片を設 けているので、器具本体の開口縁と化粧枠との突き合わせ部分にできる隙間の方 向が器具本体の外部から到来した電磁波の伝搬方向に対して平行状態よりは直交 状態に近くなる。この結果、器具本体および化粧枠の外部から到来した電磁波が 、器具本体および化粧枠の突き合わせ部分の隙間を通して器具本体の内部に漏れ 込むのを低減することができる。 According to the configuration of the present invention, since the horizontal piece for receiving the main body, which is provided on the upper edge of the decorative frame so as to face the opening edge of the instrument body, is provided with the rising piece that rises on the inner peripheral side of the instrument body, The direction of the gap formed at the abutting portion of the opening edge of the device body and the decorative frame is closer to the orthogonal state than the parallel state to the propagation direction of the electromagnetic wave coming from the outside of the device body. As a result, it is possible to reduce electromagnetic waves coming from the outside of the device body and the decorative frame from leaking into the inside of the device body through the gap between the abutting portions of the device body and the decorative frame.
【００１０】 したがって、この照明器具を電磁シールドルームの天井に設置した場合におい て、器具本体および化粧膜の隙間を通して漏れ出る電磁波を抑制することができ 、電磁シールドルームにおける電磁シールド機能を損なうことが少ない。Therefore, when the lighting fixture is installed on the ceiling of the electromagnetic shield room, electromagnetic waves leaking through the gap between the main body of the fixture and the decorative film can be suppressed, and the electromagnetic shield function in the electromagnetic shield room may be impaired. Few.
【００１１】[0011]
この考案の一実施例を図１ないし図６に基づいて説明する。この照明器具は、 図１に示すように、下面を開放して内部に例えば直管型の蛍光ランプ１１が配置 される箱形の器具本体１２の開口に化粧枠１３を取り付けている。 器具本体１２は、図４ないし図６に示すように、４個の両側縁を直角に折り曲 げた側板１２ａを方形に組み合わせ、方形に組み合わせた４個の側板１２ａの上 端縁に四周を直角に折り曲げた天板１２ｂを被せた構造である。なお、４個の側 板１２ａと天板１２ｂは、例えばスポット溶接等によって一体固定される。１５ は天井パネルである。 An embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 1, the lighting fixture has a decorative frame 13 attached to the opening of a box-shaped fixture body 12 in which a lower surface is opened and a straight tube type fluorescent lamp 11 is disposed inside. As shown in FIG. 4 to FIG. 6, the instrument body 12 has four side plates 12a whose four side edges are bent at right angles combined in a square shape, and four side plates 12a combined in a square shape form four right angles at four edges. This is a structure in which a top plate 12b bent over is covered. The four side plates 12a and the top plate 12b are integrally fixed by spot welding or the like. Reference numeral 15 is a ceiling panel.
【００１２】 各側板１２ａ間は、重ね代を多くして、電磁シールドルームの外部、つまり器 具本体１２の外部から到来した電磁波が側板１２ａ間の隙間を通して器具本体１ ２内へ漏れ込むのを低減している。また、側板１２ａと天板１２ｂとの間は、重 ね代を多くしているのはもちろんのこと、側板１２ａと天板１２ｂとは、天板１ ２の折り曲げた端縁を外側にして側板１２ａと天板１２ｂとの重ね合わせ状態に おける露出した天板１２ｂの端縁が下向きとなるようにし、電磁シールドルーム の斜め上方から到来する、つまり照明器具の斜め上方から到来する電磁波に対し て、側板１２ａと天板１２ｂとの重ね合わせ部分の隙間への電磁波の侵入経路が 直交状態を超え逆方向に近い状態とし、電磁波が側板１２ａと天板１２ｂとの重 ね合わせ部分の隙間から器具本体１２の内部へ漏れ込むのを低減している。Between the side plates 12a, the overlap margin is increased to prevent electromagnetic waves coming from outside the electromagnetic shield room, that is, outside the equipment body 12 from leaking into the instrument body 12 through the gap between the side plates 12a. It is decreasing. In addition, the weight between the side plate 12a and the top plate 12b is increased, and the side plate 12a and the top plate 12b are the side plates with the bent edges of the top plate 12 outside. 12a and the top plate 12b are overlapped with each other so that the edge of the exposed top plate 12b faces downward so that the electromagnetic waves coming from diagonally above the electromagnetically shielded room, that is, from the diagonally above the luminaire are received. , The intrusion path of the electromagnetic wave into the gap of the overlapping portion of the side plate 12a and the top plate 12b exceeds the orthogonal state and is close to the opposite direction, and the electromagnetic wave is passed from the gap of the overlapping portion of the side plate 12a and the top plate 12b to the instrument. Leakage into the main body 12 is reduced.
【００１３】 また、化粧枠１３は、上端縁に器具本体１２の開口端縁に対向する本体受け用 水平片１３ａを設け、この本体受け用水平片１３ａに器具本体１２の内周側に立 ち上がる立ち上がり片１３ｂを設けている。この立ち上がり片１３ｂは器具本体 １２の開口縁、つまり側板１２ａの下端縁に対してビス１４で固定することによ り、器具本体１２に対して化粧枠１３が固定される。化粧枠１３には、乳白色の パネル１５が取り付けられている。Further, the decorative frame 13 is provided with a horizontal piece 13a for receiving the main body which faces the opening edge of the instrument main body 12 at the upper end edge, and the horizontal piece 13a for receiving the main body stands on the inner peripheral side of the instrument main body 12. A rising piece 13b is provided. The decorative piece 13 is fixed to the instrument body 12 by fixing the rising piece 13b to the opening edge of the instrument body 12, that is, the lower end edge of the side plate 12a with a screw 14. A milky white panel 15 is attached to the decorative frame 13.
【００１４】 このように、器具本体１２の内周側に立ち上がり片１３ｂを設けると、器具本 体１２と化粧枠１３との突き合わせ部分において、両者の隙間が照明器具の斜め 上方から到来する電磁波に対して、平行状態よりは直交状態に近くなり、器具本 体１２と化粧枠１３との間の隙間からの電磁波の器具本体１２の内部への漏れ込 みを低減することができる。この立ち上がり片１３ｂは、長いほど側板１２ａに 対する重ね代が多くなり、電磁波の漏れ込みを一層少なく抑えることができる。In this way, when the rising piece 13b is provided on the inner peripheral side of the fixture body 12, the gap between the fixture main body 12 and the decorative frame 13 at the abutting portion is against electromagnetic waves coming from diagonally above the lighting fixture. On the other hand, the state becomes closer to the orthogonal state than the parallel state, and it is possible to reduce the leakage of electromagnetic waves into the instrument body 12 from the gap between the instrument body 12 and the decorative frame 13. The longer the rising piece 13b is, the larger the overlapping margin with respect to the side plate 12a is, and the leakage of electromagnetic waves can be further suppressed.
【００１５】 したがって、この照明器具を電磁シールドルームの天井に設置した場合におい て、器具本体１２自体の隙間ならびに器具本体１２および化粧膜１３の隙間を通 して漏れ出る電磁波を抑制することができ、電磁シールドルームにおける電磁シ ールド効果を損なうことが少ない。 図３はこの考案の他の実施例における化粧枠の構造を示すものである。この実 施例では、化粧枠１３の本体受け用水平片１３ａに器具本体１２の内周側に立ち 上がる立ち上がり片１３ｂを設ける他に、器具本体１２の外周側に立ち上がる立 ち上がり片１３ｃを設け、両立ち上がり片１３ｂ，１３ｃで器具本体１２の下端 縁、つまり側板１２ｂの下端縁を挟み込むようにしたものである。Therefore, when this lighting fixture is installed on the ceiling of an electromagnetically shielded room, it is possible to suppress electromagnetic waves leaking through the gap between the fixture body 12 itself and the gap between the fixture body 12 and the cosmetic film 13. , The electromagnetic shield effect in an electromagnetically shielded room is less likely to be impaired. FIG. 3 shows the structure of a decorative frame according to another embodiment of the present invention. In this embodiment, a horizontal piece 13a for receiving the main body of the decorative frame 13 is provided with a rising piece 13b which rises on the inner peripheral side of the instrument body 12, and a rising piece 13c which is raised on the outer peripheral side of the instrument body 12 is provided. The bottom edge of the instrument body 12, that is, the bottom edge of the side plate 12b is sandwiched between the rising pieces 13b and 13c.
【００１６】 このようにすると、器具本体１２の側板１２ａの下端縁と化粧枠１３との突き 合わせ部分の重ね代が多くなり、化粧枠１３が図２のような構造である場合に比 べて、電磁波の漏れ込みを一層少なくできる。 その他の構成については、前記した実施例と同様である。In this way, the overlap margin of the abutting portion of the lower end edge of the side plate 12a of the instrument body 12 and the decorative frame 13 increases, and the decorative frame 13 has a structure as shown in FIG. The leakage of electromagnetic waves can be further reduced. Other configurations are the same as those in the above-described embodiment.
【００１７】[0017]
この考案の照明器具によれば、器具本体の開口端縁に対向するように化粧枠の 上端縁に設けた本体受け用水平片に器具本体の内周側に立ち上がる立ち上がり片 を設けているので、器具本体の開口縁と化粧枠との突き合わせ部にできる隙間の 方向が器具本体の外部から器具本体の内部へ侵入しようとする電磁波の伝搬方向 に対して平行状態よりは直交状態に近くすることができ、器具本体および化粧枠 の外部から到来した電磁波が、器具本体および化粧枠の突き合わせ部分の隙間を 通して器具本体の内部に漏れ込むのを低減することができる。 According to the luminaire of the present invention, since the horizontal piece for receiving the main body, which is provided on the upper edge of the decorative frame so as to face the opening edge of the main body of the luminaire, is provided with the rising piece that stands up on the inner peripheral side of the main body of the luminaire, The direction of the gap formed at the abutting part of the opening edge of the instrument body and the decorative frame may be closer to the orthogonal state than the parallel state to the propagation direction of the electromagnetic wave that tries to enter the inside of the instrument body from the outside of the instrument body. Therefore, it is possible to reduce electromagnetic waves coming from the outside of the device body and the decorative frame from leaking into the inside of the device body through the gap between the abutting portions of the device body and the decorative frame.
【００１８】 したがって、この照明器具を電磁シールドルームの天井に設置した場合におい て、器具本体および化粧膜の突き合わせ部分の隙間を通して漏れ込む電磁波を抑 制することができ、電磁シールドルームにおける電磁シールド効果の低下を抑制 することができる。Therefore, when this lighting fixture is installed on the ceiling of an electromagnetic shield room, it is possible to suppress electromagnetic waves leaking through the gap between the abutting portion of the main body of the fixture and the decorative film, and the electromagnetic shield effect in the electromagnetic shield room. Can be suppressed.
