It is a portion that illuminates with a predetermined brightness, and includes a light emitting portion 6 that emits light emitted from an LED element 7, which is a light emitting diode for lighting, with a predetermined light distribution. Light distribution that spreads mainly in the horizontal direction so that the light emitted from the light emitting unit 6, that is, the light emitted from the LED element 7 is distributed in the longitudinal direction of the road when the lighting fixture 1 is attached to the road in a substantially orthogonal state. A lighting fixture 1 having characteristics.

更に、具体的には、照明器具１は、不透光性の金属製の照明器具本体２（以下、器具本体２という）と、器具本体２に取り付けられ照明器具１の下方領域を照明する発光部６と、発光部６を下方から覆う透光性カバー２３を有する。
器具本体２は、上壁２Ｔと前記上壁２Ｔから下降する周囲壁２Ｓを有し、周囲壁２Ｓで囲まれた下側に開口する開口２Ａを形成した内部空間４を有するアルミニウムのダイキャスト製等の熱良導材で前後方向に長い形態に構成されている。
器具本体２は、器具本体２の後部に所定の支持部Ｐへ取り付ける取り付け部１０を備える。 More specifically, the luminaire 1 includes a non-translucent metal luminaire body 2 (hereinafter referred to as luminaire body 2) and a light emitting device attached to the luminaire body 2 that illuminates the area below the luminaire 1. It has a portion 6 and a translucent cover 23 that covers the light emitting portion 6 from below.
The device main body 2 is made of die-cast aluminum and has an upper wall 2T and a peripheral wall 2S descending from the upper wall 2T, and an internal space 4 surrounded by the peripheral wall 2S and having an opening 2A opening downward. It is made of a heat-conductive material such as the one that is long in the front-rear direction.
The instrument main body 2 has a mounting portion 10 attached to a predetermined support portion P at the rear portion of the instrument main body 2 .

開口２Ａに並行状態に臨むように前記内部空間４に発光部６が器具本体２に取り付けられる。発光部６を下方から覆って開口２Ａを塞ぐように器具本体２に取り外し可能または開閉可能に透光性カバー２３が取り付けられる。
透光性カバー２３は、上面開口の容器形態をなすように平板状の底板部の周縁部に上方へ突出する環状フランジが形成された皿状又は盆状であり、器具本体２の開口２Ａの周縁部にパッキンを介して水密状態に取り付けられる。これによって、発光部６を配置した前記内部空間４は略気密状態となる。 A light emitting part 6 is attached to the instrument main body 2 in the internal space 4 so as to face the opening 2A in parallel. A translucent cover 23 is detachably or openably closable attached to the fixture body 2 so as to cover the light emitting part 6 from below and close the opening 2A.
The light-transmitting cover 23 has a dish-like or tray-like shape with an annular flange protruding upward from the periphery of a flat plate-like bottom plate so as to form a container shape with an upper opening. It is watertightly attached to the peripheral portion via packing. As a result, the internal space 4 in which the light-emitting portion 6 is arranged becomes substantially airtight.

発光部６は、照明用ＬＥＤ素子（発光ダイオード）７が放射する光を所定の配光にて出射する部分であり、矩形状の平板状のＬＥＤ取り付け回路基板５の下側面にＬＥＤ素子７が下方へ僅かに突出状態で配置され、各ＬＥＤ素子７は、ＬＥＤ素子７の発光を所定配光にて下方へ照射するためのレンズ機能を持つ配光ユニット８で覆われている。
ＬＥＤ取り付け回路基板５はネジによりアルミニウム製の放熱板９の下側面に取り付けられ、この放熱板９が前記内部空間４に配置される状態で、器具本体２の取り付けボスへネジ止めされ、ＬＥＤ素子７の発光熱が放熱板を介して器具本体２へ伝達され、器具本体２から放散される。 The light-emitting portion 6 is a portion that emits light emitted by an illumination LED element (light-emitting diode) 7 with a predetermined light distribution. Each LED element 7 is arranged in a state of slightly protruding downward, and each LED element 7 is covered with a light distribution unit 8 having a lens function for downwardly irradiating light emitted from the LED element 7 with a predetermined light distribution.
The LED mounting circuit board 5 is attached to the lower surface of the heat sink 9 made of aluminum with screws, and in a state where the heat sink 9 is arranged in the internal space 4, it is screwed to the mounting boss of the fixture main body 2, and the LED element is mounted. The emitted heat of 7 is transferred to the fixture main body 2 via the radiator plate and dissipated from the fixture main body 2 .

ＬＥＤ素子７の発光光が照明器具１の左右方向へ長い配光をなすように、配光ユニット８は、アクリルやポリカーボネートの透明樹脂製であり、左右方向に長い半俵状・反円弧状等の形状をなすレンズ部を形成し、これによって、ＬＥＤ素子７の発光光は、楕円形状・長円形状等の左右方向に長い配光特性をなす。
このため、照明器具１が、左右方向に延びる道路に対して略直行状態の配置となるように、取り付け部１０にて所定の支持部Ｐへ取り付けられた正規の状態で、配光ユニット８によって、ＬＥＤ素子７の出射光が、照明器具１の前後方向への配光が抑制されて道路の長手方向に向かう配光となるよう、主として左右方向に長い配光となる配光特性である。 The light distribution unit 8 is made of a transparent resin such as acrylic or polycarbonate so that the light emitted from the LED element 7 is distributed in the left-right direction of the lighting fixture 1, and is shaped like a half bale, anti-arc shape, or the like, which is elongated in the left-right direction. The light emitted from the LED element 7 has a long light distribution characteristic such as an elliptical shape, an oval shape, or the like in the left-right direction.
For this reason, the lighting device 1 is mounted on the predetermined support portion P by the mounting portion 10 so that the lighting device 1 is arranged in a substantially orthogonal state with respect to the road extending in the left-right direction. , the light distribution characteristic is such that the light emitted from the LED element 7 is distributed mainly in the horizontal direction so that the light distribution in the front-rear direction of the lighting fixture 1 is suppressed and the light is distributed in the longitudinal direction of the road.

発光部６の後方位置には、ＬＥＤ素子７の点灯・消灯の電力供給制御に関わる電気回路部２０が配置されて、電気回路部２０の下側が器具本体２の取り付けボスへネジ止めされるカバー２１で覆われる。
電気回路部２０は、商用電力が供給され、ＬＥＤ素子７を点灯するために商用電力３１を直流電力に変換するＡ／Ｄ変換回路と照明器具１の周囲の照度を検出する照度センサ２５の照度検出によりＬＥＤ素子７の点灯・消灯を制御する点灯制御回路とを含むＬＥＤ点灯制御回路２０Ａと、照度センサ２５を含む照度センサ制御回路２５Ｋ等を有する。
照度センサ制御回路２５Ｋは、照度センサ２５、制御素子２５Ｓ、リレーＲＹ等を含む回路構成がセンサ基板２７に取り付けられて、絶縁シート２６で覆われる状態で器具本体２の内部空間４に取り付けられる。照度センサ２５は、器具本体２の側面に開口する採光窓２５Ｐに対応配置され、採光窓２５Ｐの外側開口はシリコンゴム製の透光部材２５Ｔで覆われており、防水構造を成す。 An electric circuit portion 20 related to power supply control for turning on/off the LED element 7 is arranged behind the light emitting portion 6, and the lower side of the electric circuit portion 20 is screwed to the mounting boss of the device main body 2. covered with 21.
The electric circuit unit 20 is supplied with commercial power, and includes an A/D conversion circuit that converts the commercial power 31 into DC power to light the LED element 7, and an illuminance sensor 25 that detects the illuminance around the lighting fixture 1. It has an LED lighting control circuit 20A including a lighting control circuit for controlling lighting and extinguishing of the LED element 7 by detection, an illuminance sensor control circuit 25K including an illuminance sensor 25, and the like.
The illuminance sensor control circuit 25K has a circuit configuration including the illuminance sensor 25, the control element 25S, the relay RY, etc. attached to the sensor substrate 27, and is attached to the interior space 4 of the fixture body 2 while being covered with the insulating sheet 26. The illuminance sensor 25 is arranged corresponding to a lighting window 25P that opens on the side of the fixture body 2, and the outer opening of the lighting window 25P is covered with a translucent member 25T made of silicon rubber to form a waterproof structure.

カバー２１を貫通して操作部３０Ａが下方へ突出するように、手動スイッチ３０が電気回路部２０の側方にてカバー２１に取り付けられ、電気回路部２０の回路に電気的接続される。
この手動スイッチ３０は、操作部３０Ａによるスイッチ切り替え操作によって、照度センサ２５の検出による発光部６の点灯・消灯制御が行われないように切り替えるものである。
上記からして、発光部６、放熱板９、電気回路部２０、カバー２１、照度センサ２５、絶縁薄板２６、センサ基板２７、手動スイッチ３０は、器具本体２の内部空間４に配置され、透光性カバー２３で覆われる。 A manual switch 30 is attached to the cover 21 on the side of the electrical circuit section 20 so that the operation section 30A protrudes downward through the cover 21, and is electrically connected to the circuit of the electrical circuit section 20. As shown in FIG.
The manual switch 30 switches so that the lighting/extinguishing control of the light emitting unit 6 based on the detection of the illuminance sensor 25 is not performed by the switch switching operation of the operation unit 30A.
From the above, the light emitting portion 6, the heat sink 9, the electric circuit portion 20, the cover 21, the illuminance sensor 25, the insulating thin plate 26, the sensor substrate 27, and the manual switch 30 are arranged in the internal space 4 of the fixture body 2, and are transparent. Covered with optical cover 23 .

照度センサ２５の検出動作として、照明器具１の周囲の照度が夜間のように暗くなったとき、そのときの照度を照度センサ２５が検出することにより、ＬＥＤ点灯制御回路２０Ａの動作によってＬＥＤ素子７を点灯状態に制御する。また照明器具１の周囲の照度が昼間のように明るくなったとき、そのときの照度を照度センサ２５が検出することにより、ＬＥＤ点灯制御回路２０Ａの動作によってＬＥＤ素子７消灯状態に制御する。
手動スイッチ３０は、通常状態では、このような動作が得られる状態にあるが、操作部３０Ａによるスイッチ切り替え操作によって、照度センサ２５の検出による発光部６の点灯・消灯制御が行われないようにするためのものである。 As the detection operation of the illuminance sensor 25, when the illuminance around the lighting fixture 1 becomes dark such as at night, the illuminance sensor 25 detects the illuminance at that time, and the LED element 7 is turned on by the operation of the LED lighting control circuit 20A. lights up. When the illuminance around the luminaire 1 becomes as bright as in the daytime, the illuminance sensor 25 detects the illuminance at that time, and the LED lighting control circuit 20A operates to control the LED element 7 to be turned off.
In a normal state, the manual switch 30 is in a state in which such an operation can be obtained. It is for

このように、通常状態では、照度センサ２５への外部の光侵入による誤動作状況にない正規の状態においては、照度センサ２５による明るさ検出により、ＬＥＤ点灯制御回路２０Ａの動作により発光部６のＬＥＤ７の点灯・消灯制御が正常に行われる。
しかし、照度センサ２５へ照明看板やその他の光源である外部の光が侵入して、夜間にもかかわらず発光部６のＬＥＤ７が点灯しない状況にあることが管理者によって確認されれば、管理者はその照明器具１は動作不良と判断する。 In this way, in a normal state, in a normal state in which there is no malfunction due to external light entering the illuminance sensor 25, the brightness is detected by the illuminance sensor 25, and the operation of the LED lighting control circuit 20A causes the LED 7 of the light emitting unit 6 to light up. The lighting and extinguishing control of is performed normally.
However, if the administrator confirms that the LED 7 of the light emitting unit 6 does not turn on even at night due to intrusion of external light, such as an illuminated signboard or other light source, into the illuminance sensor 25, the administrator determines that the lighting device 1 is malfunctioning.

その場合、本発明では、動作不良となった照明器具１は、交換することなくそのまま使用状態とするために、管理者は透光性カバー２３を取り外した状態または開いた状態で、操作部３０Ａを操作して、照度センサ２５の検出による発光部６のＬＥＤ７の点灯・消灯制御が行われないようにする。これによって、この照明器具１は照度センサ２５を備えないものと同等となる。
そして、別の外付けの照度センサ２５０を看板光やその他の外部光が入らない位置にて、照明器具の取り付けポール等へ取り付け、その外付けの照度センサ２５０の検出動作によって、発光部の点灯・消灯の制御を行うように、ＬＥＤ点灯制御回路２０Ａへの電力供給を制御し、夜間に発光部のＬＥＤを点灯し、昼間は消灯するようにすれば、問題が解決する。 In such a case, according to the present invention, in order to put the malfunctioning lighting fixture 1 into use without replacing it, the administrator removes or opens the translucent cover 23 and opens the operation section 30A. is operated to prevent the LED 7 of the light emitting unit 6 from being controlled to be turned on or off by detection by the illuminance sensor 25 . As a result, the lighting fixture 1 becomes equivalent to one without the illuminance sensor 25 .
Then, another external illuminance sensor 250 is attached to a mounting pole or the like of the lighting equipment at a position where signboard light or other external light does not enter, and the light emitting part is lit by the detection operation of the external illuminance sensor 250. The problem can be solved by controlling the power supply to the LED lighting control circuit 20A so that the LED of the light emitting unit is turned on at night and turned off during the daytime so as to control turning off.

一つの実施例を図１に示す。図１は、照明器具１が上記のような動作不良にならない設置状態にあり、正常動作を行う状態の発光制御回路１Ｋの構成である。この場合、スイッチ３０は接点を開いた状態に設定され、照明器具１の周囲の照度が昼間のように明るいときは、そのときの照度を照度センサ２５が検出し、制御素子２５Ｓの動作によりリレーＲＹは非励磁にてその接点は開いており、ＬＥＤ点灯制御回路２０Ａへの電力供給は絶たれ、ＬＥＤ素子７は消灯状態である。
照明器具１の周囲の照度が夜間のように暗くなったとき、そのときの照度を照度センサ２５が検出することにより、制御素子２５Ｓの動作によりリレーＲＹは励磁されその接点が閉じ、ＬＥＤ点灯制御回路２０Ａへ電力供給状態となり、ＬＥＤ素子７を点灯状態に制御する。 One embodiment is shown in FIG. FIG. 1 shows the configuration of the light emission control circuit 1K when the lighting device 1 is installed in such a state that it does not malfunction as described above and is in a state of normal operation. In this case, the switch 30 is set to open the contact, and when the illuminance around the luminaire 1 is as bright as daytime, the illuminance sensor 25 detects the illuminance at that time, and the control element 25S operates to relay. RY is de-energized and its contact is open, the power supply to the LED lighting control circuit 20A is cut off, and the LED element 7 is in the off state.
When the illuminance around the lighting fixture 1 becomes dark like at night, the illuminance sensor 25 detects the illuminance at that time, and the relay RY is excited by the operation of the control element 25S to close its contact, thereby controlling the lighting of the LED. Power is supplied to the circuit 20A, and the LED element 7 is controlled to light up.

図１の回路において、上記のように、照度センサ２５へ照明看板やその他の光源である外部の光が侵入して、夜間にもかかわらず発光部６のＬＥＤ７が点灯しない状況にあることが管理者によって確認されれば、管理者はその照明器具１は動作不良と判断する。
その場合は、その照明器具１の操作部３０Ａを操作してスイッチ３０の接点を閉じる。これによって、照度センサ２５の検出信号が実質的にＬＥＤ点灯制御回路２０Ａへ作用しない回路構成となり、リレーＲＹは励磁されその接点が閉じ、ＬＥＤ点灯制御回路２０Ａは電力供給状態となり、ＬＥＤ素子７を点灯状態に制御する。この場合の照明器具１は、停電がない限り商用電力３１が供給されている間はＬＥＤ素子７は点灯状態となる。
すなわち、照明器具１は照度センサ２５を備えない照明器具と同じになり、照明器具1に商用電力３１が供給されれば、リレーＲＹは励磁されその接点が閉じ、ＬＥＤ点灯制御回路２０Ａへ電力供給状態となり、ＬＥＤ素子７を点灯モードになるものである。
すなわち、照度センサ２５の検出による発光部６のＬＥＤ素子７の点灯・消灯制御に替わって、発光部6のＬＥＤ素子７が連続点灯モードとなるように切り替える手動スイッチ３０を設けた照明器具１となる。 In the circuit of FIG. 1, as described above, it is managed that the LED 7 of the light emitting unit 6 does not turn on even at night because external light such as an illuminated signboard or other light source enters the illuminance sensor 25. If confirmed by the operator, the administrator determines that the lighting fixture 1 is malfunctioning.
In that case, the contact of the switch 30 is closed by operating the operating portion 30A of the lighting fixture 1 . As a result, the detection signal of the illuminance sensor 25 substantially does not act on the LED lighting control circuit 20A. Control the lighting state. In the lighting fixture 1 in this case, the LED element 7 is in a lighting state while the commercial power 31 is supplied as long as there is no power failure.
That is, the lighting fixture 1 becomes the same as a lighting fixture without the illuminance sensor 25, and when the commercial power 31 is supplied to the lighting fixture 1, the relay RY is energized and its contact is closed to supply power to the LED lighting control circuit 20A. In this state, the LED element 7 is put into the lighting mode.
That is, a lighting fixture 1 provided with a manual switch 30 for switching the LED element 7 of the light emitting unit 6 to a continuous lighting mode instead of turning on/off control of the LED element 7 of the light emitting unit 6 by detection of the illuminance sensor 25. Become.

このようにスイッチ３０が操作された照明器具１を照度センサによって、ＬＥＤ素子７を夜間に点灯し昼間は消灯する照明器具１とするためには、図２に示すように、照明器具１への電力供給を別の照度センサ２５０を含む外付け自動点滅器２５０Ｋの動作によって制御するように改良する。
この場合、別の外付けの照度センサ２５０は、看板光やその他の外部光が入らない位置にて、照明器具１を取り付けるポール等の支柱に取り付ける。
図２では、発光制御回路１Ｋへの電力供給を外付け自動点滅器２５０Ｋの動作によって制御し、照明器具１の周囲の照度が夜間のように暗くなったときはそれを照度センサ２５０が検出することにより、外付け自動点滅器２５０Ｋの動作によって、リレーＲＹの閉じた状態の接点を通してＬＥＤ点灯制御回路２０Ａへ電力が供給され、ＬＥＤ素子７を点灯状態に制御する。また、照明器具１の周囲の照度が昼間のように明るくなったとき、そのときの照度を照度センサ２５０が検出することにより、外付け自動点滅器２５０Ｋの動作によって、ＬＥＤ点灯制御回路２０Ａへの電力供給が絶たれ、ＬＥＤ素子７は消灯状態に制御される。 In order to turn on the lighting fixture 1 in which the switch 30 is operated in this manner by the illuminance sensor, the LED element 7 is turned on at night and turned off during the daytime, as shown in FIG. The power supply is modified to be controlled by the operation of an external flasher 250K which includes a separate illuminance sensor 250. FIG.
In this case, another external illuminance sensor 250 is attached to a post such as a pole on which the lighting fixture 1 is attached at a position where signboard light and other external light do not enter.
In FIG. 2, the power supply to the light emission control circuit 1K is controlled by the operation of the external automatic flasher 250K, and when the illuminance around the lighting fixture 1 becomes dark like at night, the illuminance sensor 250 detects it. Thus, by the operation of the external automatic flasher 250K, power is supplied to the LED lighting control circuit 20A through the closed contact of the relay RY to control the LED element 7 to the lighting state. Also, when the illuminance around the lighting fixture 1 becomes as bright as in the daytime, the illuminance sensor 250 detects the illuminance at that time, and the operation of the external automatic flasher 250K causes the LED lighting control circuit 20A to turn on. The power supply is cut off, and the LED element 7 is controlled to turn off.

これによって、動作不良となった照明器具１は、廃棄することなく、又は照度センサ２５が照明看板やその他の光源である外部の光が侵入しない位置にて器具本体２に設けられた機種に変更することなく、その動作不良となった照明器具１をそのまま継続使用できることとなる。 As a result, the malfunctioning lighting fixture 1 is not discarded, or is changed to a model in which the illuminance sensor 25 is provided in the fixture main body 2 at a position where external light such as a lighting signboard or other light sources does not enter. Without doing so, the malfunctioning lighting fixture 1 can be used continuously.

また、本発明は、照明器具１の取り付けが、後方から延びる支持部Ｐのタイプと、下方から延びる支持部Ｐのタイプの何れにも取り付け可能な構成を提供する。 In addition, the present invention provides a configuration in which the lighting device 1 can be attached to either the type of support P extending from the rear or the type of support P extending from below.

照明器具１の後方から延びる支持アームに取り付ける場合と、照明器具の下面より支持アームに取り付ける場合に適用した先行技術として、特許文献２がある。特許文献２のものは、器具本体の後面と後部下面にそれぞれポール嵌入孔を形成したものであり、照明器具本体の外側面のポール嵌入孔にポールの支持部を嵌入し、下面のポール嵌入孔をポール嵌入孔覆体で覆う。また、照明器具本体の下面のポール嵌入孔にポールを嵌入する場合は外側面のポール嵌入孔をポール嵌入孔覆体で覆う。 Japanese Patent Laid-Open Publication No. 2002-300002 discloses a prior art applied to the case of attaching to a support arm extending from the rear of the lighting fixture 1 and to the case of attaching to the support arm from the lower surface of the lighting fixture.

It is necessary to change the mounting position of the cover 8 .
In addition, in order to fix the lighting fixture body to the pole, the bolt that is screwed into a part of the pole insertion hole cover so as to project freely presses a part of the pole. It must be made of a material that allows the pole insertion hole cover to be firmly held to the device body and, conversely, to be removable.

The state of FIG. 8(a) is the first attachment mode in which the supporting tubular portion 53 described above faces downward. In this state, in order to create an inclined state with an elevation angle of 15 degrees with respect to the horizontal, the coupling screw 57 is loosened and the holder 50 is rotated with respect to the tightening bands 58A and 58B. The tightening bands 58A and 58B are coupled to the mounting bases 55A and 55B with the coupling screws 57 while the second holes 59B of the mounting bases 55A and 55B are aligned with the first holes 55P1 of the mounting bases 55A and 55B. In this state, the second inclined state is obtained in which the elevation angle of the forward rising is increased to 15 degrees.
In the case of the first inclined state such that the elevation angle is 5 degrees, the mounting configuration is returned to the first mounting configuration.

なお、取り付け基部５５Ａ、５５Ｂの間に前方と後方へ突出する突部５５Ｃを有しているため、図８（イ）の状態と図８（ニ）の状態の何れにおいても、器具本体２の後壁から前方へ向けて突出する庇壁２Ｃの下側に突部５５Ｃが入り込み、この部分の隙間を覆い隠す構成となる。これは上記第２の取り付け形態においても同様である。 In addition, since the projections 55C projecting forward and backward are provided between the mounting bases 55A and 55B, the instrument main body 2 can be mounted in both the state of FIG. 8(a) and the state of FIG. 8(d). A projecting portion 55C enters the lower side of the eaves wall 2C projecting forward from the rear wall to cover the gap of this portion. This also applies to the second attachment mode.

上記のように、透光性カバー２３で塞がれた器具本体２内の内部空間４は気密状態であるため、その内部空間４の後壁４Ａに形成した通気孔４４を水分は通過させないが通気性を有するフィルタＦＬで塞いでいる。これによって、ＬＥＤ７の点灯・消灯により内部空間４の空気膨張と収縮が生じた場合、このフィルタＦＬによって内部空間４の内外の空気流通が生じる。内部空間４の空気膨張・収縮が生じた場合、器具本体２と透光性カバー２３との気密保持のパッキンにその影響が及び、そのパッキンの劣化が早くなるが、フィルタＦＬによってそれを防止することができる。また、内部空間４の後壁４Ａには電力供給ラインの配線孔が形成され、この配線孔を弾力性のシールＢＢで気密状態、水密状態に塞いでいる。 As described above, since the internal space 4 inside the instrument body 2 closed by the translucent cover 23 is in an airtight state, moisture does not pass through the vent hole 44 formed in the rear wall 4A of the internal space 4. It is closed with a filter FL having air permeability. As a result, when the air expands and contracts in the internal space 4 due to the lighting and extinguishing of the LED 7, air circulation between the inside and outside of the internal space 4 is caused by the filter FL. When air expansion/contraction occurs in the internal space 4, the airtight packing between the device body 2 and the translucent cover 23 is affected, and the packing deteriorates quickly, but this is prevented by the filter FL. be able to. A wiring hole for a power supply line is formed in the rear wall 4A of the internal space 4, and the wiring hole is closed airtight and watertight with an elastic seal BB.

これは、照明柱の傾斜部に１ａに一定間隔で支持金具３を固定する。傾斜部１ａの全長にわたって張設されるコイルバネ２には支持金具３と同一ピッチでジグザグに屈折する針金状の芯線６が二本、菱形に組合わせて挿入され、交差部分が支持部３ｂに横向きに止着されるフックボルト３ｃに掛けられて支持され、山部と谷部とで支持金具間中央のコイルバネ２を支持する構成である。 The lighting fixture 1 of the present invention provides a technique for preventing fecal damage caused by birds perching on the top surface of the lighting fixture 1 .
Birds often perch on the upper surface of the lighting fixture 1 installed in a predetermined state, and the upper surface of the lighting fixture 1 is often soiled with their droppings. Japanese Patent Laid-Open No. 2002-200000 discloses a method for preventing fecal damage caused by birds perching on the upper surface of the lighting fixture 1 .
This fixes the support fittings 3 at regular intervals to the slanted portion of the lighting column 1a. In the coil spring 2 stretched over the entire length of the inclined portion 1a, two wire-like core wires 6 bent in a zigzag manner at the same pitch as the support metal fitting 3 are inserted in a rhomboidal combination, and the intersecting portion faces the support portion 3b sideways. The coil spring 2 in the center between the support metal fittings is supported by the peaks and valleys.

本発明の照明器具１は、解決しようとする課題として、このような構成とは異なり、鳥が止まることによる糞害の防止対策を講じると共に、照明器具１への電力供給に係る作業をし易くする技術構成を提供するものである。
その目的を達成するために、本発明の照明器具１は、照明器具１の上面に鳥が止まることによる糞害を防止するために、照明器具１の上面に延びるようにバードプロテクタ９０の取り付け部６３を開閉蓋６０の後端部に後方へ突出して備える。 The luminaire 1 of the present invention has the following problems to be solved, unlike such a configuration, it is possible to take measures to prevent fecal damage caused by perching birds and to facilitate the work related to power supply to the luminaire 1. It provides a technical configuration for
In order to achieve this purpose, the lighting fixture 1 of the present invention has a bird protector 90 mounting portion extending over the top surface of the lighting fixture 1 in order to prevent bird droppings from landing on the top surface of the lighting fixture 1 . 63 is provided at the rear end of the opening/closing lid 60 so as to protrude rearward.

照明器具１の上面に延びるようにバードプロテクタ９０をネジＮＪ３にてバードプロテクタ取り付け部６３に取り付けた状態で、開閉蓋６０を開くと、開閉蓋６０と共にバードプロテクタ９０も動き、バードプロテクタ取り付け部６３も開閉蓋６０の開閉の邪魔にならない。このため、開閉蓋６０を開く度にバードプロテクタ９０を取り外す必要もなく、バードプロテクタ９０の取り付けも簡単である。 When the bird protector 90 is attached to the bird protector attachment portion 63 by screws NJ3 so as to extend over the upper surface of the lighting fixture 1, the open/close lid 60 is opened. does not interfere with the opening and closing of the opening/closing lid 60.例文帳に追加Therefore, it is not necessary to remove the bird protector 90 every time the opening/closing cover 60 is opened, and the installation of the bird protector 90 is easy.

バードプロテクタ取り付け部６３は、開閉蓋６０の後端部に後方へ突出して設けているため、開閉蓋６０の開閉の邪魔にならない。むしろ、開閉蓋６０が斜め上後方に傾斜状態となるように開いたとき、バードプロテクタ取り付け部６３のネジＮＪ３を含む後端部（先端部）が器具本体２の後壁に衝突することにより、開閉蓋６０が開いた状態を安定的に維持できる状態を保持できることとなる。 Since the bird protector mounting portion 63 is provided at the rear end portion of the opening/closing lid 60 so as to protrude rearward, it does not interfere with the opening/closing of the opening/closing lid 60 . Rather, when the opening/closing cover 60 is opened so as to be inclined upward and rearward, the rear end portion (tip portion) including the screw NJ3 of the bird protector attachment portion 63 collides with the rear wall of the instrument main body 2. A state in which the open/close lid 60 is stably kept open can be maintained.

なお、開閉蓋６０が斜め上後方に傾斜状態となるように開くことを制限するために、開閉蓋６０の側部と器具本体２とに渡る保護紐８７を設けることがあるが、その場合、保護紐８７によって開閉蓋６０の開いた斜め状態を保持できればよいが、保護紐８７のみによってそれができない場合でも、保護紐８７とバードプロテクタ取り付け部６３との共同により、開閉蓋６０が斜め上後方に所定角度の傾斜状態となるようにすればよい。 In order to restrict the opening and closing lid 60 from being opened obliquely upward and rearward, a protective string 87 may be provided between the side portion of the opening and closing lid 60 and the device main body 2. It is sufficient if the opening and closing lid 60 can be held in an oblique open state by the protection cord 87, but even if it is not possible to do so by the protection cord 87 alone, the protection cord 87 and the bird protector mounting portion 63 jointly move the opening and closing lid 60 diagonally upward and rearward. It is only necessary to make the state of inclination at a predetermined angle.
