このため、近年、有機ＥＬ発光素子を光源として用いた照明器具が提案されている（例えば特許文献１参照）。 Conventionally, a stand-type lighting fixture using a fluorescent lamp has been proposed. Such a stand-type lighting fixture is desired to be miniaturized because it is used on a desk or the like, but it is difficult to miniaturize since a ballast is required to turn on the fluorescent lamp.

特開２００１−３２５８０５号公報（第５−７頁、第１図） That is, the lighting apparatus described in Patent Document 1 connects two supporting plates having light shielding properties so as to be openable and closable via hinges, and is provided with a surface light emitting unit made of an EL element on the opposing surface of the supporting plate. Is. In this way, by using an EL (Electro-Luminescence) element as a light source, a conventional ballast is not required, and thus the size can be reduced.

以下、本発明の実施の形態の照明器具について、図面を用いて説明する。
図１は本発明の第１の実施の形態の照明器具の収納状態を示す斜視図、図２は面状発光部材の斜視図、図３は面状発光部材の枠の断面図、図４は面状発光部材を伸長して発光部を展開した使用状態を示す斜視図、図５はコンピュータを介して電力を得る状態を示す斜視図である。 Hereinafter, the lighting fixture of embodiment of this invention is demonstrated using drawing.
FIG. 1 is a perspective view showing a storage state of a lighting fixture according to a first embodiment of the present invention, FIG. 2 is a perspective view of a planar light emitting member, FIG. 3 is a sectional view of a frame of the planar light emitting member, and FIG. FIG. 5 is a perspective view showing a state in which the planar light emitting member is extended and the light emitting unit is expanded, and FIG. 5 is a perspective view showing a state in which power is obtained via a computer.

図１〜図３に示すように、本発明の第１実施形態にかかる照明器具１０Ａは、複数の面発光部材２１が同一平面に沿って配列された面状発光部材２０と、面状発光部材２０が複数積層された発光部３０と、発光部３０を支持する支持部４０とを有している。そして、発光部３０が、各面状発光部が互いに面方向に沿って摺動することにより略階段状に伸長可能である構成を有している。   As shown in FIGS. 1 to 3, the lighting fixture 10 </ b> A according to the first embodiment of the present invention includes a planar light emitting member 20 in which a plurality of surface light emitting members 21 are arranged along the same plane, and a planar light emitting member. The light emitting unit 30 includes a plurality of stacked light emitting units 20 and a support unit 40 that supports the light emitting unit 30. And the light emission part 30 has the structure which can be expand | extended in substantially step shape, when each planar light emission part mutually slides along a surface direction.

図２に示すように、面状発光部材２０は、複数の面発光部材２１を枠２２内に配列したものである。面発光部材２１は、例えば矩形状をした有機ＥＬ発光素子であり、略１５０ｍｍ×１５０ｍｍ程度の大きさのものを４枚連結して、幅６００ｍｍの面状発光部材２０を形成することができる。なお、上述した面発光部材２１の形状、枚数、面状発光部材２０の形状は、一例であり、これに限定するものではない。また、各面発光部材２１は、単独で点灯可能となっている。   As shown in FIG. 2, the planar light emitting member 20 has a plurality of surface light emitting members 21 arranged in a frame 22. The surface light-emitting member 21 is, for example, a rectangular organic EL light-emitting element, and four surface light-emitting members 20 having a size of about 150 mm × 150 mm can be connected to form the surface light-emitting member 20 having a width of 600 mm. The shape and number of the surface light emitting members 21 and the shape of the surface light emitting member 20 described above are merely examples, and the present invention is not limited thereto. Each surface light emitting member 21 can be lit alone.

発光部３０では、複数枚（ここでは例えば３枚）の面状発光部材２０は、互いに面方向に摺動可能となっており、図３に示すように、枠２２の前後方向辺（短辺）の上下面にガイドレール２３、２４が設けられている。ガイドレール２３、２４は、互いに摺動可能に嵌合して、下側に位置する面状発光部材２０を前方へ引き出した際に、片持ちで支持できるように、例えば、一方のガイドレール２３をＴ字状断面とし、他方のガイドレール２４として、Ｔ字形状のガイドレール２３を両側から摺動可能に支持する逆Ｌ字状の２部材２４ａを設けたものとすることができる。   In the light emitting unit 30, a plurality of (for example, three) planar light emitting members 20 are slidable in the surface direction with respect to each other, and as shown in FIG. Guide rails 23 and 24 are provided on the upper and lower surfaces. The guide rails 23 and 24 are slidably fitted to each other so that, for example, one guide rail 23 can be supported in a cantilevered manner when the planar light emitting member 20 positioned on the lower side is pulled forward. And the other guide rail 24 may be provided with two inverted L-shaped members 24a that slidably support the T-shaped guide rail 23 from both sides.

複数枚の面状発光部材２０は、前述したガイドレール２３、２４によって上下方向に連結されるとともに、前後方向へ摺動可能となっており、面状発光部材２０を収納した状態では積層状態となる（図１参照）。図１に示すように、一番上の面状発光部材２０には、ＤＣ電源により駆動される有機ＥＬ発光素子を用いているため、ＡＣ／ＤＣコンバータ２５ａおよび面発光部材２１を発光させるための回路基板２５ｂが設けられており、ＡＣ／ＤＣコンバータ２５ａには電力を供給する電源線２６が接続されている。なお、ＡＣ／ＤＣコンバータ２５ａを、後述する支持部４０側に設けるようにすることもできる。   The plurality of planar light emitting members 20 are connected in the vertical direction by the guide rails 23 and 24 described above, and are slidable in the front-rear direction. When the planar light emitting members 20 are housed, they are stacked. (See FIG. 1). As shown in FIG. 1, since the top planar light emitting member 20 uses an organic EL light emitting element driven by a DC power source, the AC / DC converter 25a and the surface light emitting member 21 are caused to emit light. A circuit board 25b is provided, and a power line 26 for supplying power is connected to the AC / DC converter 25a. Note that the AC / DC converter 25a may be provided on the support portion 40 side described later.

一番上の面状発光部材２０に供給された電力は、２枚目、３枚目の面状発光部材２０に伝達される。このとき、例えばガイドレール２３、２４を用いて電力を供給することができる。すなわち、有機ＥＬ発光素子はＤＣ電源で駆動するため、左右のガイドレール２３、２４の一方（２３）にプラス、他方（２４）にマイナスを流すようにすることができる。あるいは、１本のガイドレール２３（２４）を左右に分割して電流を流すようにすることもできる。   The electric power supplied to the uppermost planar light emitting member 20 is transmitted to the second and third planar light emitting members 20. At this time, for example, power can be supplied using the guide rails 23 and 24. That is, since the organic EL light-emitting element is driven by a DC power source, it is possible to cause a plus to flow in one (23) of the left and right guide rails 23 and 24 and a minus to the other (24). Alternatively, a single guide rail 23 (24) can be divided into left and right to allow current to flow.

発光部３０は、デスク４２の上面に設けられている支持部４０としてのデスク本箱４１の下面４１ａに取付けられている。すなわち、発光部３０において最も上に位置する面状発光部材２０は、デスク本箱４１の下面４１ａに固定されており、この面状発光部材２０にその他の面状発光部材２０が摺動可能に取り付けられることになる。あるいは、デスク本箱４１の下面４１ａにガイドレール２３を設けて、最も上に位置する面状発光部材２０、も摺動可能とすることもできる（図４参照）。   The light emitting unit 30 is attached to a lower surface 41 a of a desk bookcase 41 as a support unit 40 provided on the upper surface of the desk 42. That is, the uppermost planar light emitting member 20 in the light emitting unit 30 is fixed to the lower surface 41a of the desk bookcase 41, and other planar light emitting members 20 can slide on the planar light emitting member 20. Will be attached. Or the guide rail 23 can be provided in the lower surface 41a of the desk bookcase 41, and the planar light emitting member 20 located in the uppermost part can also be slidable (refer FIG. 4).

本照明器具１０を使用する際には、収納状態（図１参照）にある積層された面状発光部材２０の、最も下にある面状発光部材２０を手前に引き出して、順次階段状に伸長させる（図４参照）。この状態で、全ての面状発光部材２０を点灯させて使用する。なお、収納状態において、最も下に位置する面状発光部材２０のみ点灯させて使用することも可能である。さらに、収納状態と伸長状態との中間の状態で面状発光部材２０を点灯させて使用するようにしてもよい。   When using the luminaire 10, the lowermost planar light emitting member 20 of the stacked planar light emitting members 20 in the housed state (see FIG. 1) is pulled out to the front, and is sequentially expanded in a stepped manner. (See FIG. 4). In this state, all the planar light emitting members 20 are turned on for use. In the housed state, it is possible to light only the planar light emitting member 20 positioned at the lowest position. Further, the planar light emitting member 20 may be turned on and used in an intermediate state between the housed state and the extended state.

以上、説明した本発明の第１実施形態にかかる照明器具１０Ａによれば、複数の面発光部材を同一平面に沿って配列するので、大面積の面状発光部材を形成することができる。さらに、この面状発光部材を複数積層して、各面状発光部材が面方向に沿って摺動して略階段状に伸長するので、大面積の発光部を得ることができるとともに、支持部により支持されるので、スタンド型の照明器具として使用することができる。また、不使用時には、発光部を形成する面状発光部材を積層状態に収容することにより、邪魔にならないようにすることができる。   As described above, according to the luminaire 10A according to the first embodiment of the present invention described above, since the plurality of surface light emitting members are arranged along the same plane, a large area surface light emitting member can be formed. Further, a plurality of the planar light emitting members are laminated, and each planar light emitting member slides along the surface direction and extends in a substantially step shape, so that a large area light emitting portion can be obtained and the support portion Therefore, it can be used as a stand-type lighting fixture. Further, when not in use, the planar light emitting member forming the light emitting portion can be accommodated in a stacked state so as not to get in the way.

また、図５に示すように、前述した照明器具１０Ａにおいて、面状発光部材２０にはコンピュータ１１（以後、［ＰＣ］と記す。）から電力が供給される接続線１２が設けられている。例えば、ＵＳＢ（Universal Serial Bus）を用いることができる。この場合、ＡＣ／ＤＣコンバータ２５ａ（図１参照）を設けることなく、ＵＳＢのＤＣ電源を利用することができる。なお、回路基板２５ｂにＰＣ連動制御回路部を設け、ＰＣ側に連動ソフトをインストールして使用する。   As shown in FIG. 5, in the lighting fixture 10 </ b> A described above, the planar light emitting member 20 is provided with a connection line 12 to which power is supplied from a computer 11 (hereinafter referred to as “PC”). For example, USB (Universal Serial Bus) can be used. In this case, a USB DC power source can be used without providing the AC / DC converter 25a (see FIG. 1). In addition, a PC interlocking control circuit unit is provided on the circuit board 25b, and interlocking software is installed and used on the PC side.

これにより、ＰＣ１１側において電力供給のＯＮ／ＯＦＦ時刻、供給電力等を設定しておけば、自動で、ＯＮ／ＯＦＦ、調光等を行うことができる。また、有機ＥＬ発光素子の省電力性を生かして、バスパワー駆動を行うことも可能である。   Thus, if the power supply ON / OFF time, power supply, etc. are set on the PC 11 side, ON / OFF, dimming, etc. can be performed automatically. In addition, it is possible to perform bus power driving by taking advantage of the power saving property of the organic EL light emitting element.

次に、本発明の第２実施形態にかかる照明器具について説明する。
