また、金属カバー2cは、プリント基板2dの長辺方向の両端部に配置した入力端子Ti、出力端子To1,To2が露出するように、プリント基板2dを覆っており、入力端子Ti、出力端子To1,To2への結線の際に金属カバー2cを取り外す必要はなく、さらに上記入力端子Ti、出力端子To1,To2は、端部の被覆を除去した単線または端部に半田上げを施した電線を差し込むことで結線が行われる速結端子であり、入力配線Wi、出力配線Wo1,Wo2を容易に接続できる。入力端子Ti、出力端子To1,To2に対して電線を差し込む方向は、筐体2aの短辺方向と同一になるように構成されており、本実施形態において入力配線Wi、出力配線Wo1,Wo2が大きく湾曲することなく接続可能であり、放電灯1の配光を遮ることなく照明器具A1の小型化に寄与している。   The metal cover 2c covers the printed circuit board 2d so that the input terminal Ti and the output terminals To1 and To2 disposed at both ends in the long side direction of the printed circuit board 2d are exposed, and the input terminal Ti and the output terminal To1. , To2, it is not necessary to remove the metal cover 2c, and the input terminal Ti and the output terminals To1 and To2 are either a single wire from which the covering of the end is removed or an electric wire with soldering applied to the end. This is a fast connection terminal where the connection is made, and the input wiring Wi and the output wirings Wo1 and Wo2 can be easily connected. The direction in which the electric wire is inserted into the input terminal Ti and the output terminals To1, To2 is configured to be the same as the short side direction of the housing 2a. In this embodiment, the input wiring Wi, the output wirings Wo1, Wo2 are It can be connected without being greatly bent, and contributes to downsizing of the lighting fixture A1 without blocking the light distribution of the discharge lamp 1.

そして、器具本体10内では、点灯装置2の一方の長辺部23を側面10aに沿って配置し、点灯装置2の他方の長辺部24に対向して放電灯1を配置しており、放電灯1および点灯装置2は、発光管1aの上記仮想軸Yと直交して発光管1aの平面形状を含む平面X(図2参照)上で互いに近接して配置されている。すなわち、二重渦巻形状の放電灯1および点灯装置2は、器具本体10内で水平方向の同一平面X上に並設されており、照明器具A1の上下方向の寸法(厚み)は、放電灯1と点灯装置2とのうち上下方向の寸法が大きいほうによって決まり、従来のように放電灯1と点灯装置2とを仮想軸Y方向に重ねて配置した場合に比べて、薄型化を図ることができる。また、点灯装置2の長辺部23に対向して放電灯1を配置することでも、器具本体10の寸法を抑えることができ、小型化を図ることができる。   And in the fixture main body 10, the one long side part 23 of the lighting device 2 is arrange | positioned along the side surface 10a, and the discharge lamp 1 is arrange | positioned facing the other long side part 24 of the lighting device 2, The discharge lamp 1 and the lighting device 2 are arranged close to each other on a plane X (see FIG. 2) perpendicular to the virtual axis Y of the arc tube 1a and including the planar shape of the arc tube 1a. That is, the double spiral discharge lamp 1 and the lighting device 2 are juxtaposed on the same horizontal plane X in the fixture body 10, and the vertical dimension (thickness) of the lighting fixture A1 is the discharge lamp. 1 and the lighting device 2, which is determined by the larger vertical dimension, and is thinner than the conventional case where the discharge lamp 1 and the lighting device 2 are arranged in the virtual axis Y direction. Can do. In addition, by disposing the discharge lamp 1 so as to face the long side portion 23 of the lighting device 2, the size of the fixture body 10 can be suppressed, and the size can be reduced.

さらに、放電灯1の発熱は上方に伝達されるので、放電灯1に対して水平方向に配置された点灯装置2には放電灯1の発熱が伝わり難くなり、点灯装置2内の電子部品が厳しい温度条件下に置かれることはない。したがって、点灯装置2内の電子部品に小形のものを用いることや、点灯装置2を放電灯1に近づけることが可能となって、薄型化、小型化が一層容易となる。   Further, since the heat generated by the discharge lamp 1 is transmitted upward, it is difficult for heat generated by the discharge lamp 1 to be transmitted to the lighting device 2 disposed in the horizontal direction with respect to the discharge lamp 1, and the electronic components in the lighting device 2 are It is not subjected to severe temperature conditions. Therefore, it is possible to use a small electronic component in the lighting device 2 or to bring the lighting device 2 closer to the discharge lamp 1, and it is easier to reduce the thickness and size.

また、器具本体10の側面10aの一端側には、入力配線Wiを引き込むための挿通孔10bが穿設され、点灯装置2は、入力端子Tiが挿通孔10bの近傍に位置するように、入力端子Tiを側面10aの一端側に向けて配置される。この入力配線Wiは、挿通孔10bから入力端子Tiまで最短距離で引き回されて出力配線Wo1,Wo2と互いに交差、接触しないように配線されている。したがって、出力配線Wo1,Wo2を流れる高周波電流によって入力配線Wiに誘起される雑音が低減され、小型化による雑音端子電圧の性能悪化を抑制している。   In addition, an insertion hole 10b for drawing the input wiring Wi is formed on one end side of the side surface 10a of the instrument body 10, and the lighting device 2 is configured so that the input terminal Ti is positioned in the vicinity of the insertion hole 10b. The terminal Ti is arranged toward one end side of the side surface 10a. The input wiring Wi is routed from the insertion hole 10b to the input terminal Ti at the shortest distance so that it does not cross and contact the output wirings Wo1 and Wo2. Therefore, noise induced in the input wiring Wi by the high-frequency current flowing through the output wirings Wo1 and Wo2 is reduced, and performance deterioration of the noise terminal voltage due to downsizing is suppressed.

次に、点灯装置2の筐体2a内には、図5に示す、AC/DCコンバータ部2mと、インバータ部2nと、出力部2oとで構成された点灯回路が収納されている。   Next, a lighting circuit composed of an AC / DC converter unit 2m, an inverter unit 2n, and an output unit 2o shown in FIG. 5 is housed in the housing 2a of the lighting device 2.

AC/DCコンバータ部2mは、入力端子Tiを介して入力された商用電源ACを全波整流する全波整流器DBと、全波整流器DBの出力端間に接続されたコンデンサC1と、全波整流器DBの+側出力に接続されたインダクタL1とダイオードD1との直列回路と、インダクタL1を介して全波整流器DBの出力端間に接続されたFET等のスイッチング素子Q1と、ダイオードD1を介してスイッチング素子Q1に並列接続された平滑用のコンデンサC2と、コンバータ制御回路K1とで構成される。そして、コンバータ制御回路K1がスイッチング素子Q1をオン・オフ制御することによって、商用電源ACの全波整流電圧を所望の直流電圧に変換し、コンデンサC2の両端から出力する。   The AC / DC converter unit 2m includes a full-wave rectifier DB for full-wave rectifying the commercial power supply AC input via the input terminal Ti, a capacitor C1 connected between output terminals of the full-wave rectifier DB, and a full-wave rectifier. A series circuit of an inductor L1 and a diode D1 connected to the + side output of DB, a switching element Q1 such as an FET connected between the output terminals of the full-wave rectifier DB via the inductor L1, and a diode D1 A smoothing capacitor C2 connected in parallel to the switching element Q1 and a converter control circuit K1 are included. Then, the converter control circuit K1 performs on / off control of the switching element Q1, thereby converting the full-wave rectified voltage of the commercial power supply AC into a desired DC voltage and outputting it from both ends of the capacitor C2.

インバータ部2nは、AC/DCコンバータ部2mの出力端間に接続されたFET等のスイッチング素子Q2,Q3(ハイサイド側スイッチング素子Q2、ローサイド側スイッチング素子Q3)の直列回路と、インバータ制御回路K2とからなるハーフブリッジインバータで構成される。そして、インバータ制御回路K2がスイッチング素子Q2,Q3を交互にオン・オフすることで、矩形波電圧を出力する。   The inverter unit 2n includes a series circuit of switching elements Q2 and Q3 (high-side switching element Q2, low-side switching element Q3) such as FETs connected between output terminals of the AC / DC converter unit 2m, and an inverter control circuit K2. It consists of a half-bridge inverter consisting of Then, the inverter control circuit K2 alternately turns on and off the switching elements Q2 and Q3 to output a rectangular wave voltage.

出力部2oは、スイッチング素子Q3の両端間に、コンデンサC3とインダクタL2の直列回路、出力端子To1(電源側端子To11、非電源側端子To12)、コンデンサC4、出力端子To2(電源側端子To21、非電源側端子To22)を接続して構成されており、スイッチング素子Q3の高圧側は、コンデンサC3とインダクタL2の直列回路を介して出力端子To1の電源側端子To11に接続され、スイッチング素子Q3の低圧側は、出力端子To2の電源側端子To21に接続される。そして、出力端子To1を一対の出力配線Wo1を介してソケット4に接続することで、電源側端子To11―非電源側端子To12間には放電灯1のフィラメント1gが接続され、また出力端子To2を一対の出力配線Wo2を介してソケット5に接続することで、電源側端子To21―非電源側端子To22間には放電灯1のフィラメント1hが接続される。さらに、非電源側端子To12−To22間にはコンデンサC4が接続される。   The output unit 2o has a series circuit of a capacitor C3 and an inductor L2, an output terminal To1 (power supply side terminal To11, non-power supply side terminal To12), a capacitor C4, and an output terminal To2 (power supply side terminal To21, between both ends of the switching element Q3. Non-power supply side terminal To22) is connected, and the high voltage side of switching element Q3 is connected to power supply side terminal To11 of output terminal To1 via a series circuit of capacitor C3 and inductor L2, and switching element Q3 The low voltage side is connected to the power supply side terminal To21 of the output terminal To2. Then, by connecting the output terminal To1 to the socket 4 via the pair of output wires Wo1, the filament 1g of the discharge lamp 1 is connected between the power supply side terminal To11 and the non-power supply side terminal To12, and the output terminal To2 is connected. By connecting to the socket 5 via the pair of output wires Wo2, the filament 1h of the discharge lamp 1 is connected between the power supply side terminal To21 and the non-power supply side terminal To22. Further, a capacitor C4 is connected between the non-power supply side terminals To12 and To22.

そして、インバータ部2nが出力した矩形波電圧は、コンデンサC3によって直流成分がカットされ、さらにインダクタL2とコンデンサC4とのLC共振回路の共振作用によって、放電灯1の始動電圧、点灯電圧を得ている。また、このLC共振回路の経路には放電灯1のフィラメント1g,1hが介挿されており、コンデンサ予熱方式となっている。   The rectangular wave voltage output from the inverter unit 2n is cut in the DC component by the capacitor C3, and further, the starting voltage and the lighting voltage of the discharge lamp 1 are obtained by the resonance action of the LC resonance circuit of the inductor L2 and the capacitor C4. Yes. In addition, filaments 1g and 1h of the discharge lamp 1 are inserted in the path of the LC resonance circuit, which is a capacitor preheating system.

ここで、交流電源ACのいずれか1線がアースされている場合、フィラメント1gおよび出力配線Wo1の対地間電圧をV1とし、フィラメント1hおよび出力配線Wo2の対地間電圧をV2とすると、対地間電圧V1は商用電源ACの電圧の一部に、インバータ部2nが出力する高周波電圧が重畳した電圧であり、対地間電圧V1>対地間電圧V2の関係が成り立つ。すなわち、出力配線Wo1が高圧側配線となり、出力配線Wo2が低圧側配線となる。   Here, when any one line of the AC power supply AC is grounded, the ground-to-ground voltage of the filament 1g and the output wiring Wo1 is V1, and the ground-to-ground voltage of the filament 1h and the output wiring Wo2 is V2. V1 is a voltage in which the high-frequency voltage output from the inverter 2n is superimposed on a part of the voltage of the commercial power supply AC, and the relationship of ground voltage V1> ground voltage V2 is established. That is, the output wiring Wo1 is a high-voltage side wiring, and the output wiring Wo2 is a low-voltage side wiring.

上記回路構成において、出力配線Wo1−Wo2間には、図6の概略図に示すような寄生容量Ckが発生し、寄生容量Ckは、出力配線Wo1,Wo2の配線間距離、配線長に密接に関係している。この寄生容量Ckの発生は、コンデンサC4の容量が増加することと等価であり、コンデンサC4の見かけ上の容量増加はインダクタL2とコンデンサC4との共振特性に影響を及ぼし、放電灯1に印加される電圧が減少するので、放電灯1の始動、点灯性能が悪化する。また、放電灯1のような二重渦巻形状の放電灯は、管長が長いために始動電圧が高く、特に始動特性は寄生容量Ckの影響を受けやすい。したがって、放電灯1の始動、点灯性能の悪化を防止するためには、寄生容量Ckによる放電灯1の印加電圧低下を抑制する必要がある。   In the above circuit configuration, a parasitic capacitance Ck as shown in the schematic diagram of FIG. 6 is generated between the output wirings Wo1 and Wo2, and the parasitic capacitance Ck is closely related to the distance between the wirings of the output wirings Wo1 and Wo2, and the wiring length. Involved. The generation of the parasitic capacitance Ck is equivalent to an increase in the capacitance of the capacitor C4. The apparent increase in the capacitance of the capacitor C4 affects the resonance characteristics of the inductor L2 and the capacitor C4 and is applied to the discharge lamp 1. Therefore, the starting and lighting performance of the discharge lamp 1 deteriorates. Further, a double spiral discharge lamp such as the discharge lamp 1 has a high starting voltage due to its long tube length, and the starting characteristic is particularly susceptible to the parasitic capacitance Ck. Therefore, in order to prevent the start-up and lighting performance of the discharge lamp 1 from deteriorating, it is necessary to suppress a decrease in the applied voltage of the discharge lamp 1 due to the parasitic capacitance Ck.

そこで、本実施形態では、図1に示すようにソケット4をソケット5より点灯装置2の出力端子Toに近い位置に配置することで、高圧側の出力配線Wo1の配線長を低圧側の出力配線Wo2の配線長より短くしている。図7は、出力配線Wo1,Wo2の各配線長と放電灯1に印加される電圧(コンデンサC4の両端電圧)との関係を実際に測定した結果である。出力配線Wo1,Wo2の各配線長が同一の20cmの場合を基準として、両方の配線長が35cmまたは50cmになった場合、あるいは一方の配線長が35cmで他方の配線長が50cmになった場合のコンデンサC4の両端電圧を測定している。この測定結果によると、出力配線Wo1,Wo2の配線長が長くなるほどコンデンサC4の両端電圧は低下するが、一方の配線長が変わらず、他方の配線長のみが長くなった場合にはコンデンサC4の両端電圧が殆ど変化しない。すなわち、出力配線Wo1,Wo2の配線長に差がある場合は、いずれか短いほうの配線長でコンデンサC4の両端電圧の低下度が決まっており、本実施形態では高圧側の出力配線Wo1の配線長を低圧側の出力配線Wo2の配線長より短くすることで、寄生容量Ckによる電圧低下を抑制し、さらには雑音性能の向上も図っている。なお、本実施形態では、高圧側の出力配線Wo1の配線長を13.5cm、低圧側の出力配線Wo2の配線長を28.0cmに設定する。   Therefore, in the present embodiment, as shown in FIG. 1, the socket 4 is arranged at a position closer to the output terminal To of the lighting device 2 than the socket 5, so that the wiring length of the high-voltage side output wiring Wo <b> 1 is reduced. The wiring length is shorter than Wo2. FIG. 7 shows the results of actual measurement of the relationship between the wiring lengths of the output wirings Wo1 and Wo2 and the voltage applied to the discharge lamp 1 (the voltage across the capacitor C4). When the wiring lengths of the output wirings Wo1 and Wo2 are the same 20 cm, both wiring lengths are 35 cm or 50 cm, or one wiring length is 35 cm and the other wiring length is 50 cm The voltage across the capacitor C4 is measured. According to this measurement result, the voltage at both ends of the capacitor C4 decreases as the wiring length of the output wirings Wo1 and Wo2 increases. However, when one wiring length does not change and only the other wiring length increases, the capacitor C4 The voltage at both ends hardly changes. That is, when there is a difference between the wiring lengths of the output wirings Wo1 and Wo2, the degree of decrease in the voltage across the capacitor C4 is determined by the shorter wiring length. In this embodiment, the wiring of the output wiring Wo1 on the high voltage side is determined. By making the length shorter than the wiring length of the output wiring Wo2 on the low voltage side, the voltage drop due to the parasitic capacitance Ck is suppressed, and further the noise performance is improved. In the present embodiment, the wiring length of the high-voltage side output wiring Wo1 is set to 13.5 cm, and the wiring length of the low-voltage side output wiring Wo2 is set to 28.0 cm.

したがって、発光管1aの両端部1b,1cに設けた口金1q,1rを介してフィラメント1g,1hに電力供給する場合、視覚的に面光源になるという二重渦巻形状の放電灯1の特長を生かすために、出力配線Wo1,Wo2を放電灯1に重ならないように引き回すと、配線長が長くなってしまい、出力配線Wo1,Wo2間に発生する寄生容量Ckによって、電気特性、特に放電灯1に印加される高周波電圧に大きな影響を及ぼしてしまうが、本実施形態のように高圧側の出力配線Wo1の配線長を低圧側の出力配線Wo2の配線長より短くすることで、出力配線Wo1,Wo2を放電灯1に重ならないように引き回しながら、寄生容量Ckの影響を低減できる。   Therefore, when the electric power is supplied to the filaments 1g and 1h via the caps 1q and 1r provided at both ends 1b and 1c of the arc tube 1a, the feature of the double spiral discharge lamp 1 is that it is visually a surface light source. If the output wirings Wo1 and Wo2 are routed so as not to overlap the discharge lamp 1 in order to save, the wiring length becomes long, and the electric characteristics, particularly the discharge lamp 1 are caused by the parasitic capacitance Ck generated between the output wirings Wo1 and Wo2. However, by making the wiring length of the high-voltage side output wiring Wo1 shorter than the wiring length of the low-voltage side output wiring Wo2 as in this embodiment, the output wiring Wo1, While routing Wo2 so as not to overlap the discharge lamp 1, the influence of the parasitic capacitance Ck can be reduced.

(実施形態2)
図8は、本実施形態の照明器具A2を側方から見た平面透視図であり、後面(図8の奥の面)が前面(図8の手前の面)より広い函状の器具本体15を備え、後面を構造物の壁等に固定して設置される。器具本体15内の後面内側には、二重渦巻形状の放電灯1と、点灯装置2と、ランプホルダー3と、ソケット4,5とを配置し、点灯装置2の入力端子Ti、出力端子To1,To2には、器具本体15の後面に穿設した挿通孔15eを介して商用電源から入線された入力配線Wi、およびソケット4,5からの出力配線Wo1,Wo2が各々接続されて、放電灯1へ高周波電力を供給している。基本構成は実施形態1と同様であり、器具本体15内では、点灯装置2の長辺部24を側面15aに沿って配置し、点灯装置2の長辺部23に対向して放電灯1を配置しており、放電灯1および点灯装置2は、発光管1aの上記仮想軸Yと直交して発光管1aの平面形状を含む平面上で互いに近接して配置されている。すなわち、二重渦巻形状の放電灯1および点灯装置2は、器具本体15内で同一平面上に並設されており、照明器具A1の前後方向の寸法は、放電灯1と点灯装置2とのうち前後方向の寸法が大きいほうによって決まり、従来のように放電灯1と点灯装置2とを仮想軸Y方向に重ねて配置した場合に比べて、薄型化を図ることができる。また、点灯装置2の長辺部23に対向して放電灯1を配置することでも、器具本体15の寸法を抑えることができ、小型化を図ることができる。
(Embodiment 2)
FIG. 8 is a plan perspective view of the illuminating device A2 of the present embodiment as viewed from the side, and a box-shaped device body 15 whose rear surface (the back surface in FIG. 8) is wider than the front surface (the front surface in FIG. 8). And the rear surface is fixed to the wall of the structure. A double spiral discharge lamp 1, a lighting device 2, a lamp holder 3, and sockets 4 and 5 are arranged inside the rear surface inside the appliance body 15, and an input terminal Ti and an output terminal To 1 of the lighting device 2 are arranged. , To2 are connected to the input wiring Wi that is inserted from the commercial power supply through the insertion hole 15e formed in the rear surface of the instrument body 15 and the output wirings Wo1 and Wo2 from the sockets 4 and 5, respectively. 1 is supplying high frequency power. The basic configuration is the same as that of the first embodiment. In the appliance main body 15, the long side portion 24 of the lighting device 2 is arranged along the side surface 15 a, and the discharge lamp 1 is opposed to the long side portion 23 of the lighting device 2. The discharge lamp 1 and the lighting device 2 are disposed close to each other on a plane including the planar shape of the arc tube 1a perpendicular to the virtual axis Y of the arc tube 1a. That is, the double spiral-shaped discharge lamp 1 and the lighting device 2 are arranged in parallel on the same plane in the fixture body 15, and the dimensions of the lighting fixture A 1 in the front-rear direction are the same as those of the discharge lamp 1 and the lighting device 2. Of these, it is determined by the larger dimension in the front-rear direction, and the thickness can be reduced as compared with the conventional case where the discharge lamp 1 and the lighting device 2 are arranged in the virtual axis Y direction. Further, by arranging the discharge lamp 1 so as to face the long side portion 23 of the lighting device 2, the size of the instrument main body 15 can be suppressed, and the size can be reduced.

さらに、放電灯1の発熱は上方に伝達されるので、放電灯1に対して水平方向に配置された点灯装置2には放電灯1の発熱が伝わり難くなり、点灯装置2内の電子部品が厳しい温度条件下に置かれることはない。したがって、点灯装置2内の電子部品に小形のものを用いることや、点灯装置2を放電灯1に近づけることが可能となって、薄型化、小型化が一層容易となる。   Further, since the heat generated by the discharge lamp 1 is transmitted upward, it is difficult for heat generated by the discharge lamp 1 to be transmitted to the lighting device 2 disposed in the horizontal direction with respect to the discharge lamp 1, and the electronic components in the lighting device 2 are It is not subjected to severe temperature conditions. Therefore, it is possible to use a small electronic component in the lighting device 2 or to bring the lighting device 2 closer to the discharge lamp 1, and it is easier to reduce the thickness and size.

本実施形態では、図8において、二重渦巻形状の放電灯1の発光領域として、放電灯1の中心から半径aの点線で示した仮想円領域H1を設定すると、仮想円領域H1の側面15a側の端部から側面15a方向へ距離b離れたところに、短辺部21,22の長さがcである点灯装置2を、長辺部23が放電灯1に対向するように配置している。ここで、半径a=60mm、距離b=15mm、長さc=150mmであり、2(a+b)=cの関係が成立しており、点灯装置2によって放電灯1の光が遮光される領域H2は、仮想円領域H1の中心から側面15a側の回転角90度の範囲内に抑えられる。   In the present embodiment, in FIG. 8, when the virtual circular area H1 indicated by the dotted line with the radius a from the center of the discharge lamp 1 is set as the light emitting area of the double spiral discharge lamp 1, the side surface 15a of the virtual circular area H1 is set. The lighting device 2 in which the length of the short side portions 21 and 22 is c is disposed at a distance b in the direction of the side surface 15a from the end portion on the side so that the long side portion 23 faces the discharge lamp 1. Yes. Here, the radius a = 60 mm, the distance b = 15 mm, the length c = 150 mm, the relationship of 2 (a + b) = c is established, and the region H <b> 2 where the light of the discharge lamp 1 is shielded by the lighting device 2. Is suppressed within a range of a rotation angle of 90 degrees on the side surface 15a side from the center of the virtual circle region H1.

このとき、点灯装置2の長辺部23,24の寸法dは、仮想円領域H1の直径2aの1.0〜1.3倍に設定されており、放電灯1の大きさから推測される必要な出力電力に対して、点灯装置2の十分な実装面積を確保可能な長辺部23,24の長さとなっている。   At this time, the dimension d of the long sides 23 and 24 of the lighting device 2 is set to 1.0 to 1.3 times the diameter 2a of the virtual circle region H1, and is estimated from the size of the discharge lamp 1. The long side portions 23 and 24 can secure a sufficient mounting area of the lighting device 2 with respect to the required output power.

さらに、器具本体15の互いに対向する両側面15a,15bを遮光材で形成し、器具本体15の互いに対向する上下面15c,15dを開放する(または光透過性の材料で形成する)とともに、前後面も遮光材で覆うことで、図9のように,上方の範囲H10内および下方の範囲H11内のみに、水平方向に対称な配光を施すことができ、例えば、この範囲H10,H11は、仮想円領域H1の中心から上方向および下方向の回転角90度の各範囲に設定される。また、この構成を応用すれば、直接光と間接光の両方を用いた演出や、前後面で表示を行う用途にも展開できる。   Furthermore, the opposite side surfaces 15a and 15b of the instrument main body 15 are formed of a light shielding material, and the upper and lower surfaces 15c and 15d of the instrument main body 15 facing each other are opened (or formed of a light-transmitting material). By covering the surface with a light shielding material, as shown in FIG. 9, light distribution symmetrical in the horizontal direction can be performed only in the upper range H10 and the lower range H11. For example, the ranges H10 and H11 are The rotation angle is set to a range of 90 degrees upward and downward from the center of the virtual circle area H1. In addition, if this configuration is applied, it can be developed for effects using both direct light and indirect light, and for use in displaying on the front and back surfaces.

なお、二重渦巻形状の放電灯1の発光管1aの横断面形状は、円形状に限定するものではなく、例えば、略楕円形状であっても、多角形状であってもよく、例えば多角形形状の場合、点灯装置2の長辺部23,24の寸法dは、多角形の対角線長さの1.0〜1.3倍に設定される。   The cross-sectional shape of the arc tube 1a of the double spiral discharge lamp 1 is not limited to a circular shape, and may be, for example, a substantially elliptical shape or a polygonal shape, for example, a polygonal shape. In the case of the shape, the dimension d of the long sides 23 and 24 of the lighting device 2 is set to 1.0 to 1.3 times the diagonal length of the polygon.

また、点灯装置2は入力端子Tiを下方に向けて配置され、さらに器具本体15の後面において、入力配線Wiを引き込むための挿通孔15eが側面15b側に穿設されて、挿通孔15eから器具本体15内に引き込まれた入力配線Wiは、配線固定具Dを介して器具本体15の下面15dを通り、点灯装置2の入力端子Tiに接続される。この入力配線Wiは、出力配線Wo1,Wo2と互いに交差、接触しないように配線されており、出力配線Wo1,Wo2を流れる高周波電流によって入力配線Wiに誘起される雑音が低減され、小型化による雑音端子電圧の性能悪化を抑制している。   Further, the lighting device 2 is arranged with the input terminal Ti facing downward, and further, an insertion hole 15e for drawing the input wiring Wi is formed on the side surface 15b side on the rear surface of the instrument body 15, and the instrument is inserted through the insertion hole 15e. The input wiring Wi drawn into the main body 15 passes through the lower surface 15d of the instrument main body 15 via the wiring fixture D and is connected to the input terminal Ti of the lighting device 2. The input wiring Wi is wired so as not to cross and contact the output wirings Wo1 and Wo2, and noise induced in the input wiring Wi by high-frequency current flowing through the output wirings Wo1 and Wo2 is reduced, and noise due to miniaturization. It suppresses the deterioration of terminal voltage performance.

また、ソケット4をソケット5より点灯装置2の出力端子Toに近い位置に配置することで、高圧側の出力配線Wo1の配線長を低圧側の出力配線Wo2の配線長より短くしており、出力配線Wo1,Wo2を放電灯1に重ならないように引き回しながら、寄生容量Ckの影響を低減している。   Further, by arranging the socket 4 at a position closer to the output terminal To of the lighting device 2 than the socket 5, the wiring length of the output wiring Wo1 on the high voltage side is shorter than the wiring length of the output wiring Wo2 on the low voltage side. The influence of the parasitic capacitance Ck is reduced while the wirings Wo1 and Wo2 are routed so as not to overlap the discharge lamp 1.
