The plurality of anodes 102 each have a band shape, extend along the Y direction on the substrate 100, and are juxtaposed at a constant interval. Each of the anodes 102 is made of a metal oxide conductor such as ITO (Indium Tin Oxide) or IZO (Indium Zinc Oxide), a metal such as Cr, Mo, Ni, Pt, or Au, or an alloy thereof. A bus line 104 for supplying a power supply voltage to the anode 102 is formed on each surface of the anode 102. An insulating film 103 is formed on the substrate 100 and the anode 102. On the surface of the insulating film 103, openings each extending in the Y direction are formed in stripes. Each of the openings is formed through the insulating film 103 so as to expose the surface of each of the anodes 102, and is provided at a position corresponding to each anode 102. By providing a plurality of openings on the surface of the insulating film 103, a bank made of the insulating film 103 is formed between the openings adjacent to each other as shown in FIG. . A bus line 104 for supplying a power supply voltage to the anode 102 is formed in the portion covered with the insulating film 103 on each anode 102 as shown in FIG. 4B. In each opening of the insulating film 103, a hole injection layer 105 is formed so as to cover the surface of the anode 102, and a hole transport layer 106 is laminated so as to cover the surface of the hole injection layer 105. Yes. Examples of materials for the hole injection layer 105 and the hole transport layer 106 include aromatic amine derivatives, phthalocyanine derivatives, porphyrin derivatives, oligothiophene derivatives, polythiophene derivatives, benzylphenyl derivatives, compounds in which a tertiary amine is linked by a fluorene group, hydrazone Derivatives, silazane derivatives, silanamine derivatives, phosphamine derivatives, quinacridone derivatives, polyaniline derivatives, polypyrrole derivatives, polyphenylene vinylene derivatives, polythienylene vinylene derivatives, polyquinoline derivatives, polyquinoxaline derivatives, carbon and the like. Further, an organic light emitting layer 107 extending in the Y direction is formed on the surface of the hole transport layer 106 as shown in FIGS. 4A and 4B. The organic light emitting layer 107 is formed of a fluorescent organometallic compound or the like. Actually, as shown in FIGS. 4A and 4B, the organic light emitting layer emits red light. Three organic light emitting layers 107 such as 107 R , an organic light emitting layer 107 G that emits green light, and an organic light emitting layer 107 B that emits blue light are formed on each hole transport layer 106. Thus, the region where the organic light-emitting layer 107 R for performing red light emission are formed becomes a red light emitting region, a region where the organic light-emitting layer 107 G for performing green light emission are formed becomes a green light emitting region, the organic light emitting performing blue light emission region layer 107 B is formed becomes a blue light emitting region. An electron transport layer 108 is formed so as to cover the surfaces of the organic light emitting layers 107 R , 107 G and 107 B and the surface of the insulating film 103, and a plate-like cathode is formed so as to cover the surface of the electron transport layer 108. 109 is formed. The cathode 109 is made of a metal having a low work function, such as Al or a compound thereof, or an alloy containing them.
　上記した構成により、広面発光部１３では、陰極１０９及び陽極１０２間に印加された電圧に応じた輝度でその陽極１０２に対応した位置、つまり陽極１０２の真上に形成されている有機発光層１０７が発光する。例えば、陰極１０９を接地電位に固定した状態で、有機発光層１０７Ｒに対応した位置に形成されている陽極１０２に電圧を印加すると、この印加電圧に応じた輝度で有機発光層１０７Ｒが赤色に発光する。また、有機発光層１０７Ｇに対応した位置に形成されている陽極１０２に電圧を印加すると、この印加電圧に応じた輝度で有機発光層１０７Ｇが緑色に発光する。また、有機発光層１０７Ｂに対応した位置に形成されている陽極１０２に第３電圧を印加すると、この印加電圧に応じた輝度で有機発光層１０７Ｂが青色に発光する。この際、広面発光部１３の光放出面からは、上記した如き赤、緑、青の光を混合した単一色の照明光が放出される。例えば、赤、緑、青の各色毎に２５６階調分の輝度を割り当てると、広面発光部１３の各々は、照明光の発光色として、１６，７７７，２１６色、いわゆるフルカラーを表現することが可能となる。広面発光部１３の各々は、制御部２０から供給された照明制御電圧に応じた輝度及び色を有する照明光を生成する。 With the configuration described above, in the wide surface light emitting unit 13, the organic light emitting layer 107 formed at a position corresponding to the anode 102 with a luminance corresponding to the voltage applied between the cathode 109 and the anode 102, that is, directly above the anode 102. Emits light. For example, when a voltage is applied to the anode 102 formed at a position corresponding to the organic light emitting layer 107 R with the cathode 109 fixed at the ground potential, the organic light emitting layer 107 R is red with a luminance corresponding to the applied voltage. Flashes on. When a voltage is applied to the anode 102 formed at positions corresponding to the organic light emitting layer 107 G, the organic light emitting layer 107 G emits green with luminance according to the applied voltage. Moreover, the application of a third voltage to the anode 102 formed at positions corresponding to the organic light emitting layer 107 B, the organic light emitting layer 107 B with a luminance corresponding to the applied voltage emits blue light. At this time, the single-color illumination light in which the red, green, and blue lights as described above are mixed is emitted from the light emission surface of the wide-surface light emitting unit 13. For example, when 256 gradations of luminance are assigned to each of red, green, and blue, each of the wide surface light emitting units 13 can express 16,777,216 colors, so-called full colors, as the emission colors of illumination light. It becomes possible. Each of the wide surface light emitting units 13 generates illumination light having luminance and color corresponding to the illumination control voltage supplied from the control unit 20.
　狭面発光部１４は、指向性を有する光、つまり上記した拡散光よりも狭い面積範囲内を照射するビーム光、すなわちスポット光を発生する照明素子である。狭面発光部１４は、金属やプラスチックなどの遮光性部材からなる円筒筐体１４ａと、円筒筐体１４ａの内部に収容された複数のＬＥＤ素子（発光ダイオード）１４ｂとにより構成される。円筒筐体１４ａは、図３（ａ）及び（ｂ）に示すように、フレーム１１の貫通孔１２を貫通した状態で支持軸１４ｃを介してフレーム１１に支持されている。円筒筐体１４ａは、支持軸１４ｃを回転中心としてフレーム１１に対して回動自在となっており、図３（ｃ）に示す如きＬＥＤ素子１４ｂから発せられるビーム光の光軸ＣＣの方向、つまり照射方向（照射角度）が可変となっている。照射方向（照射角度）の変更は、作業者による手作業、或いは図３（ｂ）に示す如くフレーム１１に設置されている駆動部１６によって実施される。駆動部１６は、ＬＥＤ素子１４ｂから発せられるビーム光の光軸ＣＣの方向を変更させるべく、円筒筐体１４ａを、支持軸１４ｃを回転中心として回動する。尚、ＬＥＤ素子１４ｂの輝度は、制御部２０から供給された照明制御電圧に応じて調整される。 The narrow surface light emitting portion 14 is a lighting element that generates light having directivity, that is, beam light that irradiates within an area range narrower than the above-described diffused light, that is, spot light. The narrow surface light-emitting part 14 is comprised by the cylindrical housing | casing 14a which consists of light-shielding members, such as a metal and a plastic, and the some LED element (light emitting diode) 14b accommodated in the inside of the cylindrical housing | casing 14a. As shown in FIGS. 3A and 3B, the cylindrical housing 14 a is supported by the frame 11 through the support shaft 14 c in a state of passing through the through hole 12 of the frame 11. The cylindrical housing 14a is rotatable with respect to the frame 11 with the support shaft 14c as the center of rotation, and the direction of the optical axis CC of the light beam emitted from the LED element 14b as shown in FIG. The irradiation direction (irradiation angle) is variable. The irradiation direction (irradiation angle) is changed manually by the operator or by the drive unit 16 installed on the frame 11 as shown in FIG. The drive unit 16 rotates the cylindrical housing 14a around the support shaft 14c as the center of rotation in order to change the direction of the optical axis CC of the light beam emitted from the LED element 14b. The luminance of the LED element 14b is adjusted according to the illumination control voltage supplied from the control unit 20.
　２つの狭面発光部１４は、図３（ａ）及び図３（ｂ）に示すように、広面発光部１３の配列方向に沿って設けられている。狭面発光部１４の１つはフレーム１１の端部（すなわち広面発光部１３よりも外側）に設けられ、狭面発光部１４の他の１つはフレーム１１の他端部よりもやや中央寄りの位置において２つの広面発光部１３の間に設けられている。すなわち、図３（ｂ）に示す如き複数の広面発光部１３による発光中心ＣＬに対して、２つの狭面発光部１４の内の一方は距離Ｓ１だけ離間した位置に設置されており、他方は距離Ｓ２（Ｓ１≠Ｓ２）だけ離間した位置に設置されている。尚、ここで、発光中心ＣＬとは、フレーム１１の表面上での広面発光部１３各々の発光中心同士を結ぶ線分によって形成される図形の重心の位置とする。 The two narrow surface light emitting portions 14 are provided along the arrangement direction of the wide surface light emitting portions 13 as shown in FIGS. 3 (a) and 3 (b). One of the narrow surface light emitting portions 14 is provided at an end portion of the frame 11 (that is, outside the wide surface light emitting portion 13), and the other one of the narrow surface light emitting portions 14 is slightly closer to the center than the other end portion of the frame 11. It is provided between the two wide surface light emitting portions 13 at the position. That is, as shown in FIG. 3B, one of the two narrow surface light-emitting portions 14 is installed at a distance S1 from the light emission center CL by the plurality of wide-surface light emitting portions 13, and the other is It is installed at a position separated by a distance S2 (S1 ≠ S2). Here, the light emission center CL is the position of the center of gravity of the figure formed by the line segment connecting the light emission centers of the wide light emitting portions 13 on the surface of the frame 11.
　要するに、２つの狭面発光部１４は、複数の広面発光部１３による発光中心ＣＬを挟んで非対象な位置に夫々配置されているのである。 In short, the two narrow surface light emitting portions 14 are respectively arranged at non-target positions across the light emission center CL of the plurality of wide surface light emitting portions 13.
　図１に示す制御部２０は、照明パターン指定信号に基づき、広面発光部１３の各々毎に、その広面発光部１３の発光輝度及び発光色を個別に制御する。 The control unit 20 shown in FIG. 1 individually controls the emission luminance and emission color of the wide surface light emitting unit 13 for each wide surface light emitting unit 13 based on the illumination pattern designation signal.
　また、制御部２０は、照明パターン指定信号に基づき、狭面発光部１４の各々毎に、その狭面発光部１４の発光輝度及び光軸方向を個別に制御する。すなわち、制御部２０は、照明パターン指定信号によって指定された輝度で狭面発光部１４を発光させるべき照明制御電圧を生成して狭面発光部１４に供給する。また、制御部２０は、照明パターン指定信号によって指定された照射角でビーム光を照射させるべく、その照射角に対応した回動角の分だけ狭面発光部１４（円筒筐体１４ａ）を回動させるべき駆動電圧を生成しこれを駆動部１６に供給する。つまり、制御部２０は、駆動部１６による狭面発光部１４に対する回動角を制御することにより、狭面発光部１４から照射されるビーム光の光軸方向を変更するのである。 Further, the control unit 20 individually controls the light emission luminance and the optical axis direction of the narrow surface light emitting unit 14 for each narrow surface light emitting unit 14 based on the illumination pattern designation signal. That is, the control unit 20 generates an illumination control voltage for causing the narrow surface light emitting unit 14 to emit light with the luminance specified by the illumination pattern specifying signal, and supplies the illumination control voltage to the narrow surface light emitting unit 14. Further, the control unit 20 rotates the narrow surface light emitting unit 14 (cylindrical casing 14a) by the rotation angle corresponding to the irradiation angle in order to irradiate the beam light with the irradiation angle specified by the illumination pattern specifying signal. A drive voltage to be moved is generated and supplied to the drive unit 16. That is, the control unit 20 changes the optical axis direction of the beam light emitted from the narrow surface light emitting unit 14 by controlling the rotation angle of the driving unit 16 with respect to the narrow surface light emitting unit 14.
　更に、制御部２０は、照明パターン指定信号に基づき、広面発光部１３の各々毎に、その広面発光部１３の輝度及び発光色を個別に制御する。すなわち、制御部２０は、照明パターン指定信号によって指定された発光色の照明光を発生させるべく、広面発光部１３の有機発光層１０７Ｒを挟む電極（１０２、１０９）間、有機発光層１０７Ｇを挟む電極間、有機発光層１０７Ｂを挟む電極間に、夫々個別に電圧を印加する。要するに、制御部２０は、赤色発光領域（１０７Ｒ）、緑色発光領域（１０７Ｇ）及び青色発光領域（１０７Ｂ）各々での輝度を個別に制御することにより、広面発光部１３が発する照明光の発光色を変更するのである。 Further, the control unit 20 individually controls the brightness and emission color of the wide surface light emitting unit 13 for each wide surface light emitting unit 13 based on the illumination pattern designation signal. That is, the control unit 20, the illumination pattern designation signal so as to generate the illumination light of the specified emission color by broad surface between the electrodes sandwiching the organic light emitting layer 107 R of the light-emitting portion 13 (102 and 109), an organic light-emitting layer 107 G between electrodes sandwiching a, between the electrodes sandwiching the organic light emitting layer 107 B, and applies the respective individual voltage. In short, the control unit 20 individually controls the luminance in each of the red light emitting region (107 R ), the green light emitting region (107 G ), and the blue light emitting region (107 B ), thereby illuminating light emitted from the wide surface light emitting unit 13. The emission color is changed.
　このような制御部２０の動作により、広面発光部１３の各々は、照明パターン指定信号によって指定された輝度及び発光色（例えば１６，７７７，２１６色色の内の１の色）の照明光を下方に向けて照射する。一方、狭面発光部１４は、照明パターン指定信号によって指定された輝度を有するビーム光を、この照明パターン指定信号によって指定された照射角にて下方に向けて照射する。 By such an operation of the control unit 20, each of the wide surface light emitting units 13 lowers the illumination light of the luminance and emission color (for example, one of 16,777,216 color colors) designated by the illumination pattern designation signal. Irradiate toward. On the other hand, the narrow surface light emitting unit 14 irradiates the light beam having the luminance designated by the illumination pattern designation signal downward at the illumination angle designated by the illumination pattern designation signal.
　尚、照明パターン指定信号とは、時刻、照射対象物、照明設置環境に応じて自動生成されるもの、或いはリモートコントロール装置（図示せぬ）から無線送出されるものである。例えば、リモートコントロール装置は、上記した如き照明パターン（輝度、発光色、照射角）を示す情報を入力する為の操作面を備え、その操作面で入力された照明パターンを示す照明パターン指定信号を制御部２０に向けて無線送信する。 The illumination pattern designation signal is automatically generated according to the time, irradiation object, and illumination installation environment, or is transmitted wirelessly from a remote control device (not shown). For example, the remote control device includes an operation surface for inputting information indicating the illumination pattern (brightness, emission color, irradiation angle) as described above, and an illumination pattern designation signal indicating the illumination pattern input on the operation surface.
