Description

本発明は、有機ＥＬや無機ＥＬ等のＥＬ（Electro Luminescence）を利用する照明パネル、この照明パネルに電力を供給する照明パネル用電源供給装置、及び照明パネルと照明パネル用電源供給装置とを備えた照明装置に関する。   The present invention includes an illumination panel that uses EL (Electro Luminescence) such as organic EL and inorganic EL, an illumination panel power supply device that supplies power to the illumination panel, and an illumination panel and illumination panel power supply device. The present invention relates to a lighting device.

長寿命が要求される分野での使用を目的とした照明装置として、発光ダイオード（ＬＥＤ）等の点光源を用いた照明装置や、有機発光ダイオード（ＯＬＥＤ）等の面発光素子を用いた照明装置等が提案されている。例えば、有機発光ダイオードを用いた固体素子型の照明装置として、面照明光源と、この面照明光源を着脱可能に保持するソケットとを有する構成のものが提案されている（例えば、特許文献1参照）。   Illumination devices that use point light sources such as light emitting diodes (LEDs) and illumination devices that use surface light emitting elements such as organic light emitting diodes (OLEDs) as illumination devices intended for use in fields that require a long life Etc. have been proposed. For example, a solid-state illumination device using an organic light-emitting diode has been proposed that includes a surface illumination light source and a socket that detachably holds the surface illumination light source (see, for example, Patent Document 1). ).

このようなソケット式の照明装置にあっては、照明装置を設置する壁面等にソケットを取り付けてあれば、ソケットに面照明光源の電極部分を装着させて接続するだけで電気的な配線工事が不要であるので、その点では都合がよい。しかし、このソケット式の照明装置にあっては、スペース面照明光源をソケットから着脱時の電極部分の磨耗や損傷が避けられず、長期間の使用には不向きである。また、ソケットに取り付ける電極部分は照明装置の周囲に設けられるため、そのスペース確保が簡単ではなく、照明装置全面を発光面とすることが難しい。特に、複数の照明装置を並べて連続した大きな発光面を形成することが簡単ではない。   In such a socket-type lighting device, if the socket is attached to the wall surface or the like where the lighting device is installed, the electrical wiring work can be performed simply by attaching and connecting the electrode portion of the surface lighting source to the socket. This is convenient because it is unnecessary. However, this socket type illumination device cannot avoid wearing or damaging the electrode portion when the space surface illumination light source is attached to or detached from the socket, and is not suitable for long-term use. Further, since the electrode portion attached to the socket is provided around the lighting device, it is not easy to secure the space, and it is difficult to make the entire lighting device the light emitting surface. In particular, it is not easy to form a continuous large light emitting surface by arranging a plurality of lighting devices.

また、有機ＥＬを用いる場合等では、有機ＥＬ自体水分に強いものではないので、電極部の構造も封止処理を考慮したものとならざるを得ない。   Further, in the case of using organic EL, etc., the organic EL itself is not resistant to moisture, and therefore the structure of the electrode portion must be taken into consideration for the sealing process.

In the present embodiment, the light emitting unit 22 is fixed to the surface of the translucent substrate 21 opposite to the exit surface from which the light from the light emitting unit 22 is emitted (a surface on the sealed space side described later).

発光部２２は、透光性基板２１の後述する封止空間側の面に積層されており、この外表面は封止層２２４で封止されている。この発光部２２は、少なくとも、１対の電極、つまりＩＴＯ電極２２１及び金属電極２２２と、このＩＴＯ電極２２１及び金属電極２２２との間に配置されたＥＬ発光層２２３との３層が積層されて構成されるＥＬ発光層２２３では、内部で生成されるホール(正孔)と電子とが結合する際に発光するようになっており、この光を照明光として利用するようになっている。なお、本実施形態では、発光部２２に有機ＥＬ素子を用い、特にこれに限定されるものではなく、発光部に無機ＥＬ素子を用いてもよい。また、有機ＥＬ素子の駆動は、直流電圧駆動でも交流電圧駆動でもよい。   The light emitting unit 22 is laminated on a surface of the translucent substrate 21 which will be described later, and the outer surface is sealed with a sealing layer 224. The light emitting unit 22 is formed by laminating at least three layers of a pair of electrodes, that is, an ITO electrode 221 and a metal electrode 222 and an EL light emitting layer 223 disposed between the ITO electrode 221 and the metal electrode 222. The EL light-emitting layer 223 is configured to emit light when holes (holes) and electrons generated inside are combined, and this light is used as illumination light. In the present embodiment, an organic EL element is used for the light emitting unit 22, and the present invention is not particularly limited thereto, and an inorganic EL element may be used for the light emitting unit. Further, the driving of the organic EL element may be DC voltage driving or AC voltage driving.

発光電源部２３は、図４に示すように、外部巻線１１１と誘導結合するための誘導巻線２３１と、この誘導巻線２３１が巻回され、外部に開放された磁路を形成するフェライト等で形成されたコア部材２３２とを備えている。   As shown in FIG. 4, the light-emitting power supply unit 23 includes an induction winding 231 for inductively coupling with the external winding 111, and a ferrite that forms the magnetic path opened to the outside by winding the induction winding 231.

Therefore, the magnetic path formed in the core member 232 is released in a direction intersecting with the emission surface of the translucent substrate 21 from which light from the light emitting unit 22 is emitted, and in a direction opposite to the emission surface side. As shown in FIG. 4, the induction winding 231 of the present embodiment is aligned and wound around the outer periphery of the bobbin 233, and the core portion of the core member 232 is inserted into the center of the bobbin 233.

封止部材２４は、透光性基板２１の一面に固着されており、特に、この透光性基板２１と封止部材２４との間に形成される空間（これを「封止空間」とよぶ）に外部から湿気が流入しないように気密状態を保持した状態で取り付けられている。   The sealing member 24 is fixed to one surface of the translucent substrate 21. In particular, a space formed between the translucent substrate 21 and the sealing member 24 (this is referred to as “sealing space”). ) In an airtight state so that moisture does not flow in from the outside.

次に、照明装置の電源供給について、図６を参照しながら説明する。電源供給装置１は、第１スイッチＳＷ１を介して商用電源Ｖに接続された整流用のダイオードブリッジＤ１及び平滑用のコンデンサＣ１と、交流生成用のインバータＩと、１次コイルを構成する外部巻線１１１と、第２スイッチＳＷ２とを備えている。第１スイッチＳＷ１は、壁面に取り付けて照明装置と商用電源との間の電気的な接続を断接させるためのものであり、第２スイッチＳＷ２は引張することで断接させる手元スイッチである。なお、照明パネル２の発光部２２が複数のもので構成されている場合には、この第２スイッチＳＷ２の操作で、一部の発光部２２を断接させるように構成してもよい。   Next, power supply of the lighting device will be described with reference to FIG. The power supply device 1 includes a rectifying diode bridge D1 and a smoothing capacitor C1, which are connected to a commercial power source V via a first switch SW1, an AC generating inverter I, and an external winding constituting a primary coil. A line 111 and a second switch SW2 are provided. The first switch SW1 is a hand switch that is attached to a wall surface to connect / disconnect the electrical connection between the lighting device and the commercial power source, and the second switch SW2 is a hand switch that is connected / disconnected by pulling. In addition, when the light emission part 22 of the illumination panel 2 is comprised by the several thing, you may comprise so that some light emission parts 22 may be connected / disconnected by operation of this 2nd switch SW2.

照明パネル２の誘導巻線２３１は、１次コイル（外部巻線１１１）に近接状態で対向配置させ電磁誘導によって起電力を発生させる２次コイルを構成しており、誘導巻線２３１に誘導された電圧が発光部２２に印加され、発光部２２が発光する。   The induction winding 231 of the lighting panel 2 constitutes a secondary coil that is disposed opposite to the primary coil (external winding 111) in a close state and generates electromotive force by electromagnetic induction, and is induced by the induction winding 231. The applied voltage is applied to the light emitting unit 22, and the light emitting unit 22 emits light.

照明パネル２には、図６（Ｂ）に示すように、誘導巻線２３１に誘導された電圧を整流、平滑する駆動回路２５を設けてもよい。駆動回路２５は、整流用のダイオードＤ２及び平滑用のコンデンサＣ２を含んで構成される。   The lighting panel 2 may be provided with a drive circuit 25 that rectifies and smoothes the voltage induced in the induction winding 231 as shown in FIG. The drive circuit 25 includes a rectifying diode D2 and a smoothing capacitor C2.

次に、本実施形態の照明装置の取付け方法について説明する。本実施形態の照明装置を設置面（例えば天井面１００）に設置する場合、この照明装置を取り付ける建物等を建設する際に、予めこの照明装置を設置する天井面１００側に凹所１００Ａを形成しておくとともに、商用電源からこの照明装置に電力を供給させるため、商用電源と電源供給装置１を電気的に接続させた状態で凹所１００Ａに電源供給装置１を予め埋設させておく。
そして、この照明装置を使用する使用者が電源供給装置１に合わせて取り付けることができる照明パネル２を用意し、天井面の電源供給装置１に封止部材２４が対面するように取り付ける。換言すれば、透光性基板２１が室内に臨むような状態で、電源供給装置１又は天井面１００に設けてある図示外の取付金具等に照明パネル２を係合若しくは螺着させて取り付ける。 Next, the attachment method of the illuminating device of this embodiment is demonstrated. When the lighting device of this embodiment is installed on an installation surface (for example, the ceiling surface 100), when a building or the like to which the lighting device is attached is constructed, a recess 100A is formed in advance on the ceiling surface 100 side where the lighting device is installed. In addition, in order to supply power to the lighting device from a commercial power source, the power supply device 1 is embedded in advance in the recess 100A in a state where the commercial power source and the power supply device 1 are electrically connected.
And the illumination panel 2 which the user who uses this illuminating device can attach according to the power supply device 1 is prepared, and it attaches so that the sealing member 24 may face the power supply device 1 of a ceiling surface. In other words, the lighting panel 2 is attached to the power supply device 1 or a mounting bracket (not shown) provided on the ceiling surface 100 by being engaged or screwed with the translucent substrate 21 facing the room.

以上のように、照明パネル２には電気的な接続を行うことなく取り付けできるので、取り付けを簡単に行うことができる。また、天井面から突出している部分は、照明パネル１だけであり、照明パネル２は、発光部２２に有機ＥＬを用いることにより、大幅な薄型化を図ることができるので、外観上も見栄がよい設置が可能となる。   As described above, since the lighting panel 2 can be attached without being electrically connected, the attachment can be easily performed. Further, the portion protruding from the ceiling surface is only the lighting panel 1, and the lighting panel 2 can be significantly reduced in thickness by using the organic EL for the light emitting portion 22, so that the appearance is also excellent. Good installation is possible.
