Description

この発明は、照明装置に係り、特に外部電源から電源ケーブルを介して供給される電力により照明を行う板状の照明装置に関する。   The present invention relates to an illumination device, and more particularly to a plate-like illumination device that performs illumination with electric power supplied from an external power supply via a power cable.

ハロゲン電球や放電ランプを光源として用いる従来の照明装置は、器具が大型化するだけでなく、発光に伴う発熱量が大きいために、取り扱いにくく、特に机上や手元、人物の顔等、所望の領域のみを部分的に照明する照明装置としては不向きであった。
これに対し、例えば特許文献１には、発光ダイオードを光源とし、支持部を介して天井等に回動自在に取り付けられる照明装置が開示されている。この照明装置は、発光ダイオードを用いたことにより、薄型化及び軽量化がなされると共に発光に伴う発熱量が小さいので、上述したような所望の領域を部分的に照明するのに適している。 Conventional lighting devices that use halogen bulbs or discharge lamps as light sources are not only large in size but also difficult to handle due to the large amount of heat generated by light emission, especially on desks, hands, and human faces. It was unsuitable as an illuminating device that partially illuminates only.
On the other hand, for example, Patent Literature 1 discloses a lighting device that uses a light emitting diode as a light source and is rotatably attached to a ceiling or the like via a support portion. This lighting device is suitable for partially illuminating a desired region as described above because it uses a light-emitting diode to reduce the thickness and weight and reduce the amount of heat generated by light emission.

特開２００４−３４２３９２号公報JP 2004-342392 A

しかしながら、特許文献１の照明装置は、天井等に取り付けられるため、机上や手元、人物の顔等を自由に照明するには適したものではない。この照明装置を天井等に取り付けずに使用するとしても、電源供給用ケーブルが平板状の器具本体の背面に固定されているので、照明装置を机上等に載置した際に背面から電源供給用ケーブルを取り回さなければならず、照明装置の配置が電源供給用ケーブルによって制限を受けるという問題を生じてしまう。   However, since the illumination device of Patent Document 1 is attached to a ceiling or the like, it is not suitable for freely illuminating a desk, a hand, a human face, or the like. Even if this lighting device is used without being mounted on the ceiling or the like, the power supply cable is fixed to the back of the flat fixture body, so when the lighting device is placed on a desk or the like, The cable has to be routed, which causes a problem that the arrangement of the lighting device is limited by the power supply cable.

この発明は、このような従来の問題点を解消するためになされたもので、薄型で取り扱いやすく且つ配置の自由度を向上させることができる照明装置を提供することを目的とする。   The present invention has been made to solve such a conventional problem, and an object of the present invention is to provide a lighting device that is thin, easy to handle, and capable of improving the degree of freedom in arrangement.

この発明に係る照明装置は、外部電源から電源ケーブルを介して供給される電力により照明を行う板形状の照明装置であって、板形状の筺体と、筺体内に配置された発光体と、それぞれ筺体の板厚を構成する部位に配置されると共に発光体に接続され且つ電源ケーブルの端部コネクタが連結される２つ以上の筺体側コネクタとを備え、電源ケーブルの端部コネクタを任意の筺体側コネクタに連結することにより電源ケーブルを介して発光体に電力が供給されるものである。   The illumination device according to the present invention is a plate-shaped illumination device that performs illumination with electric power supplied from an external power source via a power cable, and includes a plate-shaped housing, a light emitter disposed in the housing, and Two or more housing-side connectors that are arranged at a portion constituting the thickness of the housing and are connected to the light emitter and to which the end connector of the power cable is connected, and the end connector of the power cable is connected to any housing By connecting to the side connector, power is supplied to the light emitter via the power cable.

なお、筺体側コネクタに連結された電源ケーブルの端部コネクタにより筺体を支持するように構成することができる。この場合、電源ケーブルの端部コネクタを連結する筺体側コネクタを選択して端部コネクタを連結することによって筺体の支持角度を調整するように構成してもよい。
また、電源ケーブルの端部コネクタが連結された筺体側コネクタ以外の筺体側コネクタに接続ケーブルを介して他の照明装置の筺体側コネクタを連結することにより、他の照明装置の発光体にも外部電源から電源ケーブルと接続ケーブルを介して電力が供給されるようにすれば、ケーブルを煩雑にすることなく複数の照明装置を互いに連結して使用することができる。
発光体としては、有機エレクトロルミネッセンス素子を用いることができる。 In addition, it can comprise so that a housing may be supported by the edge part connector of the power cable connected with the housing side connector. In this case, you may comprise so that the support angle of a housing may be adjusted by selecting the housing side connector which connects the edge connector of a power cable, and connecting an edge connector.
Also, by connecting the housing side connector of another lighting device via a connection cable to the housing side connector other than the housing side connector to which the end connector of the power cable is connected, the light emitting body of the other lighting device is also externally connected. If power is supplied from the power source via the power cable and the connection cable, a plurality of lighting devices can be connected to each other without making the cable complicated.
As the light emitter, an organic electroluminescence element can be used.

この発明によれば、板形状の筺体の板厚を構成する部位に２つ以上の筺体側コネクタを配置し、電源ケーブルの端部コネクタを任意の筺体側コネクタに連結することにより電源ケーブルを介して筺体内の発光体に電力が供給されるように構成したので、薄型で取り扱いやすいだけでなく、配置の自由度が向上する。   According to the present invention, two or more housing-side connectors are arranged in a portion constituting the plate thickness of the plate-shaped housing, and the end connector of the power cable is connected to the optional housing-side connector via the power cable. In addition, since power is supplied to the light emitter in the housing, it is not only thin and easy to handle, but also the degree of freedom in arrangement is improved.

以下、この発明の実施の形態を添付図面に基づいて説明する。
実施の形態１
図１に実施の形態１に係る照明装置１の内部構成を示す。照明装置１は、板形状の筐体２内に６個の有機エレクトロルミネッセンス（以下適宜ＥＬと称する）素子３を有する面発光体４を備えている。また、筺体側コネクタとして、筐体２の両側端部のうちの一方に第１コネクタ５が、他方に第２コネクタ６が、筐体２の下端部に第３コネクタ７がそれぞれ配設されている。これら第１コネクタ５、第２コネクタ６及び第３コネクタ７は、いずれも第１ピンと第２ピンからなる２ピン構成のコネクタであり、それぞれのコネクタの第１ピンが正極用ピンとして用いられ、これら３つのコネクタの正極用ピンが筐体２内で正極線ＬＡにより互いに接続されると共に正極線ＬＡに面発光体４の各有機ＥＬ素子３の正極電極が接続されている。また、第１コネクタ５、第２コネクタ６及び第３コネクタ７の第２ピンは、それぞれ負極用ピンとして用いられ、これら負極用ピンが筐体２内で負極線ＬＣにより互いに接続されると共に負極線ＬＣに面発光体４の各有機ＥＬ素子３の負極電極が接続されている。 Embodiments of the present invention will be described below with reference to the accompanying drawings.
Embodiment 1
FIG. 1 shows an internal configuration of lighting apparatus 1 according to the first embodiment. The illumination device 1 includes a surface light emitter 4 having six organic electroluminescence (hereinafter referred to as EL) elements 3 in a plate-shaped housing 2. In addition, as the housing-side connector, the first connector 5 is disposed at one of the two side ends of the housing 2, the second connector 6 is disposed at the other, and the third connector 7 is disposed at the lower end of the housing 2. Yes. These first connector 5, second connector 6 and third connector 7 are all two-pin connectors composed of first and second pins, and the first pin of each connector is used as a positive electrode pin. The positive electrode pins of these three connectors are connected to each other by the positive electrode line LA in the housing 2, and the positive electrode of each organic EL element 3 of the surface light emitter 4 is connected to the positive electrode line LA. The second pins of the first connector 5, the second connector 6, and the third connector 7 are respectively used as negative electrode pins, and these negative electrode pins are connected to each other by a negative electrode line LC in the housing 2 and are also negative electrodes. The negative electrode of each organic EL element 3 of the surface light emitter 4 is connected to the line LC.

図２に示されるように、第１コネクタ５、第２コネクタ６及び第３コネクタ７は、それぞれ板形状の筐体２の板厚を構成する部位に配置されており、これらのコネクタのいずれかに電源ケーブル８の端部コネクタ９を連結することにより面発光体４の各有機ＥＬ素子３が電源ケーブル８を介して図示しない外部電源に接続される。従って、外部電源により各有機ＥＬ素子３を発光させて照明を行うことができる。
ここで、第１コネクタ５、第２コネクタ６及び第３コネクタ７は互いに並列に接続されているため、これらのコネクタのうちいずれに電源ケーブル８の端部コネクタ９を連結しても、面発光体４の各有機ＥＬ素子３と外部電源とが接続され、外部電源から各有機ＥＬ素子３に電力を供給することができる。すなわち、照明装置１の配置状況に応じて３つのコネクタ５〜７の中から使用するコネクタを選択することができ、照明装置１の配置の自由度が向上する。
例えば、図２に示されるように、スタンド１０によって筐体２を支持し、下方を向いた第３コネクタ７に電源ケーブル８の端部コネクタ９を連結して照明装置１を利用することもできる。 As shown in FIG. 2, the first connector 5, the second connector 6, and the third connector 7 are arranged at portions constituting the plate thickness of the plate-shaped housing 2, respectively. By connecting the end connector 9 of the power cable 8 to each other, each organic EL element 3 of the surface light emitter 4 is connected to an external power source (not shown) via the power cable 8. Therefore, each organic EL element 3 can be illuminated by an external power source for illumination.
Here, since the first connector 5, the second connector 6, and the third connector 7 are connected in parallel to each other, even if the end connector 9 of the power cable 8 is connected to any of these connectors, the surface light emission is performed. Each organic EL element 3 of the body 4 is connected to an external power source, and power can be supplied to each organic EL element 3 from the external power source. That is, a connector to be used can be selected from the three connectors 5 to 7 according to the arrangement state of the lighting device 1, and the degree of freedom of arrangement of the lighting device 1 is improved.
For example, as shown in FIG. 2, the housing 2 can be supported by a stand 10, and the end connector 9 of the power cable 8 can be connected to the third connector 7 facing downward to use the lighting device 1. .

また、図３に示されるように、筐体２に支持板１１を取り付けて照明装置１を机上等に載置することもでき、この場合には、筐体２の側端部に配設された第２コネクタ６または第１コネクタ５に電源ケーブル８の端部コネクタ９を連結すればよい。なお、机の天板に電源ケーブル８の端部コネクタ９を通す開口部が形成されていれば、図３のように照明装置１を載置した状態で天板の下方から開口部を通して第３コネクタ７に電源ケーブル８の端部コネクタ９を連結することも可能となる。このようにすれば、電源ケーブル８が目立たなくなる。   In addition, as shown in FIG. 3, the lighting device 1 can be placed on a desk or the like by attaching a support plate 11 to the housing 2, and in this case, the lighting device 1 is disposed at a side end of the housing 2. The end connector 9 of the power cable 8 may be connected to the second connector 6 or the first connector 5. In addition, if the opening part which lets the edge part connector 9 of the power cable 8 pass is formed in the top plate of a desk, in the state which mounted the illuminating device 1 like FIG. It is also possible to connect the end connector 9 of the power cable 8 to the connector 7. In this way, the power cable 8 becomes inconspicuous.

さらに、図４に示されるように、机１２等に電源ケーブル８の端部コネクタ９を外方へ突出するように固定しておき、図５に示されるように、この端部コネクタ９に照明装置１の例えば第３コネクタ７を連結させることにより、筐体２を支持させることもできる。このような構成にすれば、筐体２を支持させるためのスタンド１０や支持板１１が不要になる。   Further, as shown in FIG. 4, the end connector 9 of the power cable 8 is fixed to the desk 12 or the like so as to protrude outward, and the end connector 9 is illuminated as shown in FIG. The housing 2 can also be supported by connecting, for example, the third connector 7 of the device 1. With such a configuration, the stand 10 and the support plate 11 for supporting the housing 2 become unnecessary.

実施の形態２
図６に実施の形態２に係る照明装置２１を示す。照明装置２１は、実施の形態１の照明装置１と同様に板形状の筐体２２内に６個の有機ＥＬ素子３を有する面発光体４を備えているが、筺体側コネクタとして、筐体２２の一方の側端部に第１コネクタ２３と第２コネクタ２４とが配設されている。これら第１コネクタ２３及び第２コネクタ２４は、いずれも第１ピンと第２ピンからなる２ピン構成のコネクタであり、それぞれのコネクタの第１ピンが筐体２２内で正極線ＬＡにより互いに接続されると共に正極線ＬＡに面発光体４の各有機ＥＬ素子３の正極電極が接続されている。また、第１コネクタ２３及び第２コネクタ２４の第２ピンが筐体２２内で負極線ＬＣにより互いに接続されると共に負極線ＬＣに面発光体４の各有機ＥＬ素子３の負極電極が接続されている。
従って、第１コネクタ２３及び第２コネクタ２４のいずれに電源ケーブル８の端部コネクタ９を連結しても、外部電源から各有機ＥＬ素子３に電力を供給して発光させることができる。 Embodiment 2
FIG. 6 shows a lighting device 21 according to the second embodiment. The illuminating device 21 includes a surface light emitter 4 having six organic EL elements 3 in a plate-shaped housing 22 as in the illuminating device 1 of the first embodiment. A first connector 23 and a second connector 24 are disposed at one side end portion of 22. Each of the first connector 23 and the second connector 24 is a connector having a two-pin configuration including a first pin and a second pin, and the first pin of each connector is connected to each other by a positive line LA in the housing 22. In addition, the positive electrode of each organic EL element 3 of the surface light emitter 4 is connected to the positive electrode line LA. Further, the second pins of the first connector 23 and the second connector 24 are connected to each other by the negative electrode line LC in the housing 22, and the negative electrode of each organic EL element 3 of the surface light emitter 4 is connected to the negative electrode line LC. ing.
Therefore, even if the end connector 9 of the power cable 8 is connected to either the first connector 23 or the second connector 24, power can be supplied from the external power source to each organic EL element 3 to emit light.

また、筐体２２には、ピン２５を介して回動自在に支持部材２６が取り付けられている。支持部材２６は、筐体２２にほぼ対応した大きさの平板形状を有すると共にその両側端部にそれぞれ形成されたサイド部材２７を有しており、各サイド部材２７の端部付近にそれぞれピン２５が配設されている。
そして、図６に示されるように、第１コネクタ２３及び第２コネクタ２４のいずれかに電源ケーブル８の端部コネクタ９を連結すると、端部コネクタ９が筐体２２から側方に突出するため、端部コネクタ９が支持部材２６のサイド部材２７の上縁部に当接したところで筐体２２がそれ以上支持部材２６側に回動することが阻止され、この状態で筐体２２が支持される。 A support member 26 is attached to the housing 22 via a pin 25 so as to be rotatable. The support member 26 has a flat plate shape having a size substantially corresponding to the housing 22 and has side members 27 formed at both ends thereof, and pins 25 are provided near the end portions of the side members 27. Is arranged.
As shown in FIG. 6, when the end connector 9 of the power cable 8 is connected to one of the first connector 23 and the second connector 24, the end connector 9 protrudes sideways from the housing 22. When the end connector 9 comes into contact with the upper edge of the side member 27 of the support member 26, the casing 22 is prevented from further rotating toward the support member 26, and the casing 22 is supported in this state. The

ここで、第１コネクタ２３は、筐体２２の側端部において第２コネクタ２４よりもピン２５に近い位置に配置され、第２コネクタ２４はピン２５から遠い位置に配置されている。このため、図６に示されるように、第１コネクタ２３に電源ケーブル８の端部コネクタ９を連結したときには、筐体２２が角度θ１で支持されていたものが、図７に示されるように、第２コネクタ２４に電源ケーブル８の端部コネクタ９を連結すると、筐体２２が角度θ１より小さい角度θ２で支持されることとなる。このように、第１コネクタ２３及び第２コネクタ２４の双方から電源ケーブル８の端部コネクタ９を連結する筐体側コネクタを選択することにより、筐体２２の支持角度を調整して照明することが可能となる。   Here, the first connector 23 is disposed at a position closer to the pin 25 than the second connector 24 at the side end of the housing 22, and the second connector 24 is disposed at a position far from the pin 25. Therefore, as shown in FIG. 6, when the end connector 9 of the power cable 8 is connected to the first connector 23, the housing 22 supported at the angle θ1 is shown in FIG. When the end connector 9 of the power cable 8 is connected to the second connector 24, the housing 22 is supported at an angle θ2 smaller than the angle θ1. In this way, by selecting the housing side connector that connects the end connector 9 of the power cable 8 from both the first connector 23 and the second connector 24, the support angle of the housing 22 can be adjusted and illuminated. It becomes possible.

なお、筐体側コネクタは２つに限るものではなく、３つ以上の筐体側コネクタを筐体２２の側端部に配設して選択するようにすれば、支持角度をより細かく調整することができる。
また、筐体２２の両側端部にそれぞれ複数の筐体側コネクタを配設してもよい。 Note that the number of housing-side connectors is not limited to two, and if the three or more housing-side connectors are arranged and selected at the side end of the housing 22, the support angle can be adjusted more finely. it can.
In addition, a plurality of housing side connectors may be provided at both end portions of the housing 22.

以上のような構成の第１の照明装置Ｓ１及び第２の照明装置Ｓ２と電源ケーブル８及び接続ケーブル３８を使用することにより、第１の照明装置Ｓ１の面発光体４の各有機ＥＬ素子３の正極電極は、第１の照明装置Ｓ１の正極線ＬＡ、第１の照明装置Ｓ１の第１コネクタ３３の第１ピン、電源ケーブル８の信号線Ｌ１１及び電源部コネクタ４０の第１ピンを介して外部電源３７の電流制御回路Ｄ１の正極端子に接続される。一方、第２の照明装置Ｓ２の面発光体４の各有機ＥＬ素子３の正極電極は、第２の照明装置Ｓ２の正極線ＬＡ、第２の照明装置Ｓ２の第１コネクタ３３の第１ピン、接続ケーブル３８の信号線Ｌ２３、第１の照明装置Ｓ１の第２コネクタ３４の第３ピン、第１の照明装置Ｓ１の連絡用信号線ＬＭ、第１の照明装置Ｓ１の第１コネクタ３３の第３ピン、電源ケーブル８の信号線Ｌ１３及び電源部コネクタ４０の第３ピンを介して外部電源３７の電流制御回路Ｄ２の正極端子に接続される。   By using the first lighting device S1 and the second lighting device S2 configured as described above, the power cable 8 and the connection cable 38, each organic EL element 3 of the surface light emitter 4 of the first lighting device S1. The positive electrode of the first illumination device S1 is connected to the positive electrode LA, the first pin of the first connector 33 of the first illumination device S1, the signal line L11 of the power cable 8, and the first pin of the power connector 40. Connected to the positive terminal of the current control circuit D1 of the external power source 37. On the other hand, the positive electrode of each organic EL element 3 of the surface light emitter 4 of the second illumination device S2 is the positive line LA of the second illumination device S2, the first pin of the first connector 33 of the second illumination device S2. The signal line L23 of the connection cable 38, the third pin of the second connector 34 of the first lighting device S1, the communication signal line LM of the first lighting device S1, and the first connector 33 of the first lighting device S1. The third pin, the signal line L13 of the power cable 8 and the third pin of the power connector 40 are connected to the positive terminal of the current control circuit D2 of the external power source 37.

また、第１の照明装置Ｓ１の面発光体４の各有機ＥＬ素子３の負極電極と第２の照明装置Ｓ２の面発光体４の各有機ＥＬ素子３の負極電極は、第１の照明装置Ｓ１の負極線ＬＣ、第１の照明装置Ｓ１の第２コネクタ３４の第２ピン、接続ケーブル３８の信号線Ｌ２２、第２の照明装置Ｓ２の第１コネクタ３３の第２ピン及び第２の照明装置Ｓ２の負極線ＬＣを介して互いに接続され、さらに第１の照明装置Ｓ１の第１コネクタ３３の第２ピン、電源ケーブル８の信号線Ｌ１２及び電源部コネクタ４０の第２ピンを介して外部電源３７の電流制御回路Ｄ１及び電流制御回路Ｄ２の負極端子に接続される。   The negative electrode of each organic EL element 3 of the surface light emitter 4 of the first lighting device S1 and the negative electrode of each organic EL element 3 of the surface light emitter 4 of the second lighting device S2 are the first lighting device. The negative line LC of S1, the second pin of the second connector 34 of the first lighting device S1, the signal line L22 of the connection cable 38, the second pin of the first connector 33 of the second lighting device S2, and the second lighting. They are connected to each other via the negative line LC of the device S2, and further to the outside via the second pin of the first connector 33 of the first lighting device S1, the signal line L12 of the power cable 8, and the second pin of the power connector 40. The current control circuit D1 of the power source 37 and the current control circuit D2 are connected to the negative terminals.

このため、第１の照明装置Ｓ１の面発光体４の各有機ＥＬ素子３に外部電源３７の電流制御回路Ｄ１から、第２の照明装置Ｓ２の面発光体４の各有機ＥＬ素子３に外部電源３７の電流制御回路Ｄ２から、それぞれ独立して定電流を供給してこれら面発光体４の各有機ＥＬ素子３を発光させることができる。一般に、有機ＥＬ素子は、駆動電流によってその輝度及び色度が決定されるという特性を有しているため、上述のように、第１の照明装置Ｓ１の面発光体４の各有機ＥＬ素子３と第２の照明装置Ｓ２の面発光体４の各有機ＥＬ素子３をそれぞれ専用の電流制御回路Ｄ１及びＤ２で駆動することにより、双方の照明装置Ｓ１及びＳ２の面発光体４の各有機ＥＬ素子３における輝度及び色度の均一化を図ることが可能となる。なお、外部電源３７の調節スイッチ４１を操作することにより、双方の照明装置Ｓ１及びＳ２の面発光体４の各有機ＥＬ素子３のＯＮ／ＯＦＦ制御と輝度の調整がなされる。   For this reason, from the current control circuit D1 of the external power source 37 to each organic EL element 3 of the surface light emitter 4 of the first lighting device S1, externally to each organic EL element 3 of the surface light emitter 4 of the second lighting device S2. A constant current can be independently supplied from the current control circuit D2 of the power source 37 to cause each of the organic EL elements 3 of the surface light emitters 4 to emit light. In general, since the organic EL element has a characteristic that its luminance and chromaticity are determined by a driving current, as described above, each organic EL element 3 of the surface light emitter 4 of the first illumination device S1. And each organic EL element 3 of the surface light emitter 4 of the second illuminating device S2 are driven by dedicated current control circuits D1 and D2, respectively, so that each organic EL of the surface light emitter 4 of both the illuminating devices S1 and S2 is driven. It is possible to make the luminance and chromaticity of the element 3 uniform. In addition, by operating the adjustment switch 41 of the external power source 37, ON / OFF control and luminance adjustment of each organic EL element 3 of the surface light emitters 4 of both the lighting devices S1 and S2 are performed.

図１０に示されるように、電源ケーブル８と接続ケーブル３８を用いて第１の照明装置Ｓ１と第２の照明装置Ｓ２を数珠繋ぎに接続するので、ケーブルの配線が簡単化される。
なお、第１の照明装置Ｓ１と第２の照明装置Ｓ２は、互いに共通の構成を有しているので、これら照明装置の配置の順序を考慮する必要はない。すなわち、電源ケーブル８、第２の照明装置Ｓ２、接続ケーブル３８及び第１の照明装置Ｓ１の順序で接続してもよい。 As shown in FIG. 10, since the first lighting device S1 and the second lighting device S2 are connected in a daisy chain using the power cable 8 and the connection cable 38, the wiring of the cable is simplified.
Since the first lighting device S1 and the second lighting device S2 have a common configuration, it is not necessary to consider the order of arrangement of these lighting devices. That is, you may connect in order of the power cable 8, 2nd illuminating device S2, the connection cable 38, and 1st illuminating device S1.

第１の照明装置Ｓ１及び第２の照明装置Ｓ２は、それぞれ４つの筺体側コネクタを有しているので、外部電源３７と第１の照明装置Ｓ１及び第２の照明装置Ｓ２の接続に際し、いずれの筺体側コネクタを選択することもできる。例えば、第１の照明装置Ｓ１の第２コネクタ３４に電源ケーブル８を接続すると共に第１コネクタ３３に接続ケーブル３８を接続してもよい。同様に、接続ケーブル３８を第２の照明装置Ｓ２の第２コネクタ３４に接続することもできる。
また、第１の照明装置Ｓ１の第３コネクタ３５に電源ケーブル８の端部コネクタ９を接続すると共に、第１の照明装置Ｓ１の第４コネクタ３６と第２の照明装置Ｓ２の第３コネクタ３５との間に接続ケーブル３８を接続してもよい。
このように、各照明装置Ｓ１及びＳ２の配置の自由度が向上する。さらに、各照明装置Ｓ１及びＳ２の配置を変えた場合には、必要に応じて電源ケーブル８及び接続ケーブル３８に接続される筺体側コネクタを変えることにより、電源ケーブル８と接続ケーブル３８がからむような不具合を回避することができる。 Since each of the first lighting device S1 and the second lighting device S2 has four housing-side connectors, when the external power source 37 and the first lighting device S1 and the second lighting device S2 are connected, The housing side connector can also be selected. For example, the power cable 8 may be connected to the second connector 34 of the first lighting device S <b> 1 and the connection cable 38 may be connected to the first connector 33. Similarly, the connection cable 38 can be connected to the second connector 34 of the second lighting device S2.
The end connector 9 of the power cable 8 is connected to the third connector 35 of the first lighting device S1, and the fourth connector 36 of the first lighting device S1 and the third connector 35 of the second lighting device S2. A connection cable 38 may be connected between the two.
Thus, the freedom degree of arrangement | positioning of each illuminating device S1 and S2 improves. Further, when the arrangement of the lighting devices S1 and S2 is changed, the power cable 8 and the connection cable 38 are entangled by changing the housing side connector connected to the power cable 8 and the connection cable 38 as necessary. Can be avoided.

なお、同様にして３つ以上の照明装置を連結して外部電源に接続することもできる。
