The inner wall 4 is arranged in an intermediate region in the length direction of the accommodating portion 3. The inner wall 5 is a plurality of plate-shaped members protruding in the length direction from the other end side in the length direction of the housing 2 toward the inner wall 4 side. The inner walls 4 and 5 project from the bottom surface 2b of the housing 2 toward the cover member 60 side, and are arranged so as to come into contact with the substrate 21. The inner walls 4 and 5 are formed in a region where the light emitting element 22 of the substrate 21, which will be described later, is mounted. Further, by locating the inner wall 5 in the length direction on the back surface of the substrate 21 on which the light emitting element 22 is mounted, it is possible to efficiently conduct the heat of the light emitting element 22 during lighting. The portion of the accommodating portion 3 on the other end side of the housing 2 with the inner wall 4 interposed therebetween may be referred to as a light source side accommodating portion 3a. In the present embodiment, the light source side accommodating portion 3a has two inner walls 5 formed at predetermined intervals, but one or more inner walls 5 may be provided.

取付部6は、筐体2の長さ方向の一端側に形成される。取付部6は、筐体2の幅方向に並ぶ取付部片6a,6bを有し、例えばワイヤやクランプなどの取付部材を用いて道路の脇に設置されたポールや電柱等に取り付けられる。 The mounting portion 6 is formed on one end side of the housing 2 in the length direction. The mounting portion 6 has mounting portion pieces 6a and 6b arranged in the width direction of the housing 2, and is mounted on a pole, a utility pole, or the like installed on the side of a road by using a mounting member such as a wire or a clamp.

採光孔7、配線孔8、通気孔9は、筐体2の外部と収容部3とを連通させるようにそれぞれ設けられた貫通孔である。本実施形態では、採光孔7は長さ方向の中間部分において一端側寄りに設けられており、配線孔8、通気孔9は、取付部6を有する一端側にそれぞれ形成されている。 The lighting hole 7, the wiring hole 8, and the ventilation hole 9 are through holes provided so as to communicate the outside of the housing 2 with the accommodating portion 3.

また、装着部72は、筐体2の他端側に設けられた貫通孔である。挿入部70、受け部71、装着部72は、カバー部材60の装着に使用される。筐体2の挿入部70、受け部71、装着部72を用いたカバー部材60の装着例については、カバー部材60の説明と合わせて後述する。 Further, the mounting portion 72 is a through hole provided on the other end side of the housing 2. The insertion portion 70, the receiving portion 71, and the mounting portion 72 are used for mounting the cover member 60. An example of mounting the cover member 60 using the insertion portion 70, the receiving portion 71, and the mounting portion 72 of the housing 2 will be described later together with the description of the cover member 60.

環状溝10は、パッキン40を収容するための溝であり、照明器具1内の防水性を確保する。 The annular groove 10 is a groove for accommodating the packing 40, and secures the waterproof property in the luminaire 1.

また、筐体2の収容部3には、センサパッキン12、センサカバー13、遮光筒14、光センサ25が収容されている。 Further, the sensor packing 12, the sensor cover 13, the light-shielding cylinder 14, and the optical sensor 25 are housed in the housing portion 3 of the housing 2.

光センサ25は、照明器具1の周囲の明暗を検知して光源20を点灯および消灯する照度センサである。光センサ25は、基板21に実装され、点灯装置27に接続されている。点灯装置27は、光センサ25が検知した照度が所定値以下となった場合に光源20を点灯させ、検知された照度が所定値を超えた場合に光源20を消灯させるよう制御する。 The optical sensor 25 is an illuminance sensor that detects the light and darkness around the lighting fixture 1 and turns on and off the light source 20. The optical sensor 25 is mounted on the substrate 21 and connected to the lighting device 27. The lighting device 27 controls to turn on the light source 20 when the illuminance detected by the optical sensor 25 is equal to or less than a predetermined value, and to turn off the light source 20 when the detected illuminance exceeds the predetermined value.

センサパッキン12は、採光孔7とセンサカバー13との間の隙間を埋めるための環状のシール部材である。センサカバー13は、採光孔7内に配設され、採光孔7から入射した光を収容部3の内部に取り入れるとともに、収容部3の内部に雨水やほこりなどの異物が進入するのを防ぐ有底筒状の透光性の部材である。 The sensor packing 12 is an annular sealing member for filling a gap between the lighting hole 7 and the sensor cover 13. The sensor cover 13 is arranged in the daylighting hole 7 to take in the light incident from the daylighting hole 7 into the accommodating portion 3 and prevent foreign matter such as rainwater or dust from entering the inside of the accommodating portion 3. It is a translucent member having a bottom cylinder shape.

遮光筒14は、不透光性の部材で構成された筒状の部材である。遮光筒14は、センサカバー13の一端13a側外周を覆うようにセンサカバー13の一端13a側に差し込まれ配置されている。遮光筒14およびセンサカバー13は、互いに接していてもよく、わずかに離間していてもよい。これにより、センサカバー13から伝導された採光量をそのまま基板21上の光センサ25に伝えることができる。 The light-shielding cylinder 14 is a tubular member made of a translucent member. The light-shielding cylinder 14 is inserted and arranged on the one end 13a side of the sensor cover 13 so as to cover the outer periphery of the one end 13a side of the sensor cover 13. The light-shielding cylinder 14 and the sensor cover 13 may be in contact with each other or may be slightly separated from each other. As a result, the amount of light collected from the sensor cover 13 can be directly transmitted to the optical sensor 25 on the substrate 21.

また、遮光筒14は、基板21の第1主面21aと向かい合う端部14a側から内側に張り出す返し部14bを有する。遮光筒14は、光センサ25を収容するように光センサ25の周囲を覆いつつ、返し部14bがスペーサ26の側面に当接するように配置される。 Further, the light-shielding cylinder 14 has a return portion 14b projecting inward from the end portion 14a side facing the first main surface 21a of the substrate 21. The light-shielding cylinder 14 is arranged so that the return portion 14b abuts on the side surface of the spacer 26 while covering the periphery of the optical sensor 25 so as to accommodate the optical sensor 25.

このようにセンサカバー13、遮光筒14、光センサ25をそれぞれ配置することにより、採光孔7から入射した光を光センサ25に確実に誘導することができる。また、採光孔7から入射した光以外の光、すなわち遮光筒14の外周側および遮光筒14と基板21との間から回り込む光をより確実に遮断することができる。このため、光センサ25による照明器具1の周囲の明暗の検知精度が向上する。なお、光センサ25は基板21に実装されればよく、基板21はスペーサ26を有しなくても構わない。 By arranging the sensor cover 13, the light-shielding cylinder 14, and the optical sensor 25 in this way, the light incident from the lighting hole 7 can be reliably guided to the optical sensor 25. Further, it is possible to more reliably block light other than the light incident from the daylighting hole 7, that is, the light wrapping around from the outer peripheral side of the light-shielding cylinder 14 and between the light-shielding cylinder 14 and the substrate 21. Therefore, the accuracy of detecting the light and darkness around the lighting fixture 1 by the optical sensor 25 is improved. The optical sensor 25 may be mounted on the substrate 21, and the substrate 21 may not have the spacer 26.

次に、光源20について説明する。光源20は、基板21と、基板21の第2主面21bに実装された複数の発光素子22および点灯装置27とを有する。基板21は、例えばガラスエポキシ樹脂などの絶縁性を有する平板であり、レンズ部材30を係止するための係止孔24がレンズ部材30と向かい合う基板21の幅方向の縁部に設けられている。 Next, the light source 20 will be described. The light source 20 includes a substrate 21, a plurality of light emitting elements 22 mounted on the second main surface 21b of the substrate 21, and a lighting device 27. The substrate 21 is a flat plate having an insulating property such as glass epoxy resin, and a locking hole 24 for locking the lens member 30 is provided on the widthwise edge of the substrate 21 facing the lens member 30. ..

また、基板21の第1主面21aおよび第2主面21bには銅箔などの導電性材料で形成された配線パターンがそれぞれ施されており、適宜レジスト層が施されるようになっている。なお、基板21の材料は、絶縁材とする場合には、セラミックス材料または合成樹脂材料を適用してもよい。また、基板21の材料は、金属製としてもよく、かかる場合には、例えばアルミニウムなどの熱伝導性が良好で放熱性に優れた材料を適用するのが好ましい。基板21の表面は、光の反射率が高い白色に塗装してもよい。 Further, the first main surface 21a and the second main surface 21b of the substrate 21 are each provided with a wiring pattern formed of a conductive material such as copper foil, and a resist layer is appropriately applied. .. When the material of the substrate 21 is an insulating material, a ceramic material or a synthetic resin material may be applied. Further, the material of the substrate 21 may be made of metal, and in such a case, it is preferable to use a material having good thermal conductivity and excellent heat dissipation, such as aluminum. The surface of the substrate 21 may be painted white with high light reflectance.

発光素子22は、基板21上の配線パターンによりそれぞれ点灯装置27に接続されており、点灯装置27から直流出力が供給され、点灯装置27により点灯制御される。発光素子22は、基板21の長さ方向および幅方向に沿うように複数配置されている。発光素子22は、例えばセラミックスで形成された本体に配設されたLEDチップと、このLEDチップを封止するエポキシ系樹脂やシリコーン樹脂等のモールド用の透光性樹脂とを含む。 The light emitting element 22 is connected to the lighting device 27 by a wiring pattern on the substrate 21, DC output is supplied from the lighting device 27, and the lighting is controlled by the lighting device 27. A plurality of light emitting elements 22 are arranged along the length direction and the width direction of the substrate 21. The light emitting element 22 includes, for example, an LED chip arranged in a main body made of ceramics, and a translucent resin for molding such as an epoxy resin or a silicone resin that seals the LED chip.

LEDチップは、例えば、青色光を発する青色のLEDチップである。透光性樹脂には、蛍光体が混入されており、白色光を出射できるようにするために、青色の光とは補色の関係にある黄色系の光を放射する黄色蛍光体が使用されている。なお、LEDチップは、例えば赤色光や緑色光を発するものであってもよい。 The LED chip is, for example, a blue LED chip that emits blue light. A fluorescent substance is mixed in the translucent resin, and in order to be able to emit white light, a yellow fluorescent substance that emits yellowish light having a complementary color relationship with blue light is used. There is. The LED chip may emit red light or green light, for example.

また、LEDは、LEDチップを直接基板21に実装するようにしてもよく、また、砲弾型のLEDを実装するようにしてもよく、実装方式や形式は、特に限定されるものではない。 Further, the LED may be mounted on the substrate 21 directly with the LED chip, or may be mounted with a bullet-shaped LED, and the mounting method and format are not particularly limited.

点灯装置27は、商用交流電源に接続されており、この商用交流電源を受けて直流出力を生成し、発光素子22の点灯および消灯を制御するように構成される。点灯装置27は、基板21に実装された複数の回路部品28を有する。回路部品28は、発光素子22が実装されている第2主面21bとは異なる第1主面21aでかつ、取付部6を有する筐体2の長さ方向の一端側に実装された比較的体積の大きな電子部品である。このように筐体2の収容部3を1枚の基板21で覆うように配設することで、比較的大きな回路部品28は筐体2内の空間である収容部3に収容されることになる。このように基板21の一端側の第2主面21bには発光素子22を、他端側の第1主面21aには回路部品28をそれぞれ設けることで1枚の基板21に対して発光素子22および回路部品28を効率よく実装でき、部品点数を削減することができる。 The lighting device 27 is connected to a commercial AC power supply, and is configured to receive the commercial AC power supply to generate a DC output and control the lighting and extinguishing of the light emitting element 22. The lighting device 27 has a plurality of circuit components 28 mounted on the board 21. The circuit component 28 is a first main surface 21a different from the second main surface 21b on which the light emitting element 22 is mounted, and is relatively mounted on one end side in the length direction of the housing 2 having the mounting portion 6. It is a large-volume electronic component. By arranging the accommodating portion 3 of the housing 2 so as to be covered with one substrate 21 in this way, the relatively large circuit component 28 is accommodated in the accommodating portion 3 which is a space inside the housing 2. Become. As described above, by providing the light emitting element 22 on the second main surface 21b on one end side of the substrate 21 and the circuit component 28 on the first main surface 21a on the other end side, the light emitting element is provided for one substrate 21. 22 and the circuit component 28 can be efficiently mounted, and the number of components can be reduced.

次に、レンズ部材30について説明する。レンズ部材30は、複数の凹部32、膨出部35を一体に有する。凹部32は、基板21の第2主面21bに実装された発光素子22とそれぞれ向かい合うように配置されている。凹部32は、対応する発光素子22と向かい合うように第1面31側にそれぞれ設けられ、発光素子22を収容する。凹部32は、平面視で略楕円形状を有しており、長さ方向が基板21の長さ方向に沿うように設けられている。 Next, the lens member 30 will be described. The lens member 30 integrally has a plurality of recesses 32 and bulges 35. The recess 32 is arranged so as to face each of the light emitting elements 22 mounted on the second main surface 21b of the substrate 21. The recess 32 is provided on the first surface 31 side so as to face the corresponding light emitting element 22, and accommodates the light emitting element 22. The recess 32 has a substantially elliptical shape in a plan view, and is provided so that the length direction is along the length direction of the substrate 21.

膨出部35は、レンズ部材30の第1面31とは反対側の第2面34側に設けられており、複数の膨出部35が協働してレンズ部材30が有する光配向性を規定する。レンズ部材30は、例えば道路の幅方向および道路の長さ方向に向けて配光を制御している。特に道路の脇や歩道等に設置されて道路を照射する照明器具1では、道路の長さ方向に向けて比較的多く照射光を照射することが要求される。そのため、レンズ部材30は、筐体2の長さ方向よりも幅方向側に長い一対の膨出部35を有し、幅方向に向けて膨出部35が出射面となり、光を道路の長さ方向へ照射している。これにより、発光素子22から出射された光を基板21の長さ方向の凹部32の入射面に効率よく入射するとともに出射面である膨出部35から照射可能となる。 The bulging portion 35 is provided on the second surface 34 side opposite to the first surface 31 of the lens member 30, and the plurality of bulging portions 35 cooperate to obtain the photo-orientation of the lens member 30. Prescribe. The lens member 30 controls the light distribution, for example, in the width direction of the road and the length direction of the road. In particular, in the lighting fixture 1 installed on the side of a road, on a sidewalk, or the like to irradiate a road, it is required to irradiate a relatively large amount of irradiation light in the length direction of the road. Therefore, the lens member 30 has a pair of bulging portions 35 that are longer in the width direction than the length direction of the housing 2, and the bulging portions 35 serve as an exit surface in the width direction, and light is transmitted to the length of the road. Irradiating in the vertical direction. As a result, the light emitted from the light emitting element 22 can be efficiently incident on the incident surface of the recess 32 in the length direction of the substrate 21 and can be irradiated from the bulging portion 35 which is the emitting surface.

また、レンズ部材30は、複数の膨出部35を連結する平坦部36を有している。平坦部36は、第1面31側が基板21の発光素子22実装面である第2主面21bに接触するよう配設される。また、平坦部36から基板21の幅方向に沿う方向の両端に一対の係止部33を有する。係止部33は、基板21側に向けて突出し、基板21に設けられた係止孔24に挿入可能となるように設けられている。また、一対の係止部33は、基板21の長さ方向に沿うように延びる係止爪33aをそれぞれ有する。 Further, the lens member 30 has a flat portion 36 that connects a plurality of bulging portions 35. The flat portion 36 is arranged so that the first surface 31 side is in contact with the second main surface 21b, which is the light emitting element 22 mounting surface of the substrate 21. Further, it has a pair of locking portions 33 at both ends in the direction along the width direction of the substrate 21 from the flat portion 36. The locking portion 33 projects toward the substrate 21 side and is provided so as to be able to be inserted into the locking hole 24 provided in the substrate 21. Further, each of the pair of locking portions 33 has locking claws 33a extending along the length direction of the substrate 21.

レンズ部材30は、基板21の長さ方向にレンズ部材30をスライドさせることで係止される。具体的には、係止部33を係止孔24に差し込み、レンズ部材30の平坦部36と基板21の第2主面21bとを接触または近接させた後、レンズ部材30を取付部6側に近づけるような向きにスライドさせることでレンズ部材30が基板21に係止される。このようにレンズ部材30をスライドさせて係止することにより、発光素子22とレンズ部材30の凹部32との距離を近接することができるため、発光素子22から出射した光を、レンズ部材30を介して効率よく配光制御することが可能となる。また、例えばねじ止めによりレンズ部材30と基板21とを固定する場合と比較して部品点数を削減することができる。なお、レンズ部材30と基板21とをより確実に固定するためにねじ止めを併用してもよい。 The lens member 30 is locked by sliding the lens member 30 in the length direction of the substrate 21. Specifically, the locking portion 33 is inserted into the locking hole 24, and the flat portion 36 of the lens member 30 and the second main surface 21b of the substrate 21 are brought into contact with or close to each other, and then the lens member 30 is attached to the mounting portion 6 side. The lens member 30 is locked to the substrate 21 by sliding the lens member 30 in a direction close to the substrate 21. By sliding and locking the lens member 30 in this way, the distance between the light emitting element 22 and the recess 32 of the lens member 30 can be brought close to each other, so that the light emitted from the light emitting element 22 can be transferred to the lens member 30. It is possible to efficiently control the light distribution through the lens. Further, the number of parts can be reduced as compared with the case where the lens member 30 and the substrate 21 are fixed by screwing, for example. In addition, screwing may be used together in order to more reliably fix the lens member 30 and the substrate 21.

また、凹部32は、レンズ部材30のスライド前後で発光素子22と向かい合うようにスライド方向に延在している。このため、レンズ部材30と基板21とを係止する前後において発光素子22と凹部32との干渉を回避することができる。 Further, the recess 32 extends in the slide direction so as to face the light emitting element 22 before and after the slide of the lens member 30. Therefore, it is possible to avoid interference between the light emitting element 22 and the recess 32 before and after locking the lens member 30 and the substrate 21.

なお、凹部32は、凹部32の長さ方向が基板21の長さ方向に沿うように設けられているとしたが、これに限らず、例えば道路の幅方向に多くの光を照射させたい場合など、一対の膨出部35が長さ方向に並ぶように形成されている場合においては、長さ方向が基板21の幅方向に沿うように設けられてもよい。また、基板21に係止されるためのレンズ部材30のスライド方向を変更し、図示した方向とは反対の向きにレンズ部材30をスライドさせることでレンズ部材30が基板21に係止されるよう係止爪33aの位置を変更してもよい。 The recess 32 is provided so that the length direction of the recess 32 is along the length direction of the substrate 21, but the present invention is not limited to this, and for example, when it is desired to irradiate a large amount of light in the width direction of the road. For example, when the pair of bulging portions 35 are formed so as to be arranged in the length direction, the length direction may be provided along the width direction of the substrate 21. Further, the lens member 30 is locked to the substrate 21 by changing the sliding direction of the lens member 30 for being locked to the substrate 21 and sliding the lens member 30 in the direction opposite to the direction shown in the drawing. The position of the locking claw 33a may be changed.

また、レンズ部材30のスライド方向が基板21の幅方向に沿うよう係止部33および係止孔24の配置および形状を変更してもよい。さらに、基板21が係止部33を有し、レンズ部材30が係止孔24を有する構成としてもよい。 Further, the arrangement and shape of the locking portion 33 and the locking hole 24 may be changed so that the sliding direction of the lens member 30 is along the width direction of the substrate 21. Further, the substrate 21 may have a locking portion 33, and the lens member 30 may have a locking hole 24.

パッキン40は、例えばシリコーンゴムであり、環状溝10に収容されて筐体2とグローブ50との間の防水性を確保する。 The packing 40 is, for example, silicone rubber, and is housed in the annular groove 10 to ensure waterproofness between the housing 2 and the glove 50.

グローブ50は、底面51、周壁52、環状凸部53、仕切部54を有する。グローブ50は、例えば、アクリルやポリカーボネート等の透光性の材料から作られている。グローブ50は、フロスト処理が施されてレンズ部材30から出射される光を拡散する機能を有するようになっている。なお、グローブ50に適宜拡散材を混入させて光の拡散性をもたせるようにしてもよい。 The glove 50 has a bottom surface 51, a peripheral wall 52, an annular convex portion 53, and a partition portion 54. The glove 50 is made of a translucent material such as acrylic or polycarbonate. The glove 50 is subjected to a frost treatment and has a function of diffusing the light emitted from the lens member 30. The glove 50 may be appropriately mixed with a diffusing material to provide light diffusivity.

グローブ50の底面51は、光源20の基板21面から比較的内空間を高く形成することで、レンズ部材30により配光制御された光を効率よく照射側へ照射可能となる。 By forming the inner space of the bottom surface 51 of the glove 50 relatively high from the surface of the substrate 21 of the light source 20, it is possible to efficiently irradiate the irradiation side with the light whose light distribution is controlled by the lens member 30.

グローブ50は、パッキン40を環状凸部53で押圧するように配置され、筐体2とグローブ50との間の防水性を確保する。また、隣り合う底面51および周壁52が交差する部分は、それぞれ所定の大きさの曲率半径で面取りされ、またはアールがつけられている。このため、隣り合う底面51および周壁52が交差する部分に稜線を有する場合と比較してレンズ部材30により配光制御された光を道路の幅方向へ効率よく出射することができる。 The glove 50 is arranged so as to press the packing 40 with the annular convex portion 53, and secures waterproofness between the housing 2 and the glove 50. Further, the portion where the adjacent bottom surface 51 and the peripheral wall 52 intersect is chamfered or rounded with a radius of curvature of a predetermined size, respectively. Therefore, the light distributed by the lens member 30 can be efficiently emitted in the width direction of the road as compared with the case where the adjacent bottom surface 51 and the peripheral wall 52 have a ridge line at the intersection.

カバー部材60は、底面61、周壁62、内面63、引掛部64、固定部65を有する。カバー部材60は、例えば、アクリルやポリカーボネート等の透光性の材料から作られている。カバー部材60は、所望の光拡散性を有するようフロスト処理が施されている。また、カバー部材60に適宜拡散材や着色剤を混入させてもよい。 The cover member 60 has a bottom surface 61, a peripheral wall 62, an inner surface 63, a hooking portion 64, and a fixing portion 65. The cover member 60 is made of a translucent material such as acrylic or polycarbonate. The cover member 60 is frosted so as to have a desired light diffusivity. Further, a diffuser or a colorant may be appropriately mixed in the cover member 60.

カバー部材60は、グローブ50から出射される光をさらに拡散することでグレアの発生を低減する。また、カバー部材60は、着色剤に応じて着色された光を出射する。カバー部材60は、例えばグローブ50から出射された光が眩しいので対策したい、あるいは所望の着色光を出射させたいといった要望に応じて出射光を調整するための調整部材である。カバー部材60は、所定の設置個所に取り付けられた照明器具1においても着脱することができる。 The cover member 60 further diffuses the light emitted from the glove 50 to reduce the occurrence of glare. Further, the cover member 60 emits light colored according to the colorant. The cover member 60 is an adjusting member for adjusting the emitted light according to a request that, for example, the light emitted from the glove 50 is dazzling and a countermeasure is desired, or a desired colored light is emitted. The cover member 60 can also be attached to and detached from the lighting fixture 1 attached to a predetermined installation location.

カバー部材60の底面61および周壁62は、グローブ50の底面51および周壁52と向かい合うように形成されている。また、カバー部材60の内面63は、内部空間にグローブ50が収容できるように形成されている。内面63は、グローブ50とは離れていてもよく、また接触してもよい。 The bottom surface 61 and the peripheral wall 62 of the cover member 60 are formed so as to face the bottom surface 51 and the peripheral wall 52 of the glove 50. Further, the inner surface 63 of the cover member 60 is formed so that the glove 50 can be accommodated in the internal space. The inner surface 63 may be separated from or may be in contact with the glove 50.

引掛部64は、カバー部材60の周壁62のうち、長さ方向の一端から外側に張り出すように形成されている。引掛部64は、筐体2の挿入部70に挿入可能な形状を有している。固定部65は、カバー部材60の周壁62のうち、長さ方向の他端側に設けられた略円弧形状の切欠きである。 The hook portion 64 is formed so as to project outward from one end in the length direction of the peripheral wall 62 of the cover member 60. The hook portion 64 has a shape that can be inserted into the insertion portion 70 of the housing 2. The fixing portion 65 is a notch having a substantially arc shape provided on the other end side in the length direction of the peripheral wall 62 of the cover member 60.

カバー部材60は、引掛部64、固定部65を用いて筐体2に装着される。ここで、筐体2に対するカバー部材60の装着の一例について、図2~図4を参照して説明する。図4は、カバー部材の装着例を示す斜視図である。 The cover member 60 is attached to the housing 2 by using the hooking portion 64 and the fixing portion 65. Here, an example of mounting the cover member 60 on the housing 2 will be described with reference to FIGS. 2 to 4. FIG. 4 is a perspective view showing an example of mounting the cover member.

まず、筐体2の挿入部70に引掛部64の端部を挿入する。次に、挿入部70に挿入した引掛部64が接触または近接するように受け部71に引掛け、このままカバー部材60の他端側をグローブ50に近づけるよう、図4の矢印100に示す向きに移動させる。そして、固定部65が筐体2の装着部72と向かい合うようにカバー部材60の位置を微調整し、ねじ等の図示しない固定部材を用いて筐体2とカバー部材60とを固定する。これにより、カバー部材60の引掛部64が筐体2の受け部71に保持され、固定部65が筐体2の装着部72に固定され、カバー部材60は筐体2に装着される。 First, the end portion of the hook portion 64 is inserted into the insertion portion 70 of the housing 2. Next, the hooking portion 64 inserted into the inserting portion 70 is hooked on the receiving portion 71 so as to be in contact with or close to the receiving portion 71, and the other end side of the cover member 60 is brought closer to the glove 50 as it is in the direction shown by the arrow 100 in FIG. Move it. Then, the position of the cover member 60 is finely adjusted so that the fixing portion 65 faces the mounting portion 72 of the housing 2, and the housing 2 and the cover member 60 are fixed by using a fixing member (not shown) such as a screw. As a result, the hooking portion 64 of the cover member 60 is held by the receiving portion 71 of the housing 2, the fixing portion 65 is fixed to the mounting portion 72 of the housing 2, and the cover member 60 is mounted on the housing 2.

このようにカバー部材60は、引掛部64を用いて筐体2に装着されることにより、部品点数を削減することができ、さらにカバー部材60の装着が容易となる。また、引掛部64を保持する受け部71が、取付部6と同じ筐体2の一端側に設けられているため、照明器具1がポールや電柱等に取り付けられた状態のままであっても、カバー部材60の装着や交換作業といった着脱作業が容易になり、施工性が向上する。 By mounting the cover member 60 on the housing 2 using the hooking portion 64 in this way, the number of parts can be reduced, and the cover member 60 can be easily mounted. Further, since the receiving portion 71 for holding the hooking portion 64 is provided on one end side of the same housing 2 as the mounting portion 6, even if the lighting fixture 1 is still mounted on a pole, a utility pole, or the like. , The attachment / detachment work such as the attachment / replacement work of the cover member 60 becomes easy, and the workability is improved.

なお、上記した実施形態では、発光素子22は光センサ25が検知した明暗に基づいて点灯および消灯するとして説明したが、これに限らず、光センサ25が検知した明または暗に基づいて点灯および消灯のうち一方を実行することとしてもよい。かかる場合、点灯装置27は、例えば予め定められた時刻に発光素子22の点灯および消灯のうち他方を実行することができる。 In the above embodiment, the light emitting element 22 is turned on and off based on the light and darkness detected by the optical sensor 25, but the present invention is not limited to this, and the light emitting element 22 is turned on and off based on the light and darkness detected by the optical sensor 25. One of the lights may be turned off. In such a case, the lighting device 27 can execute the other of lighting and extinguishing of the light emitting element 22 at a predetermined time, for example.

また、上記した実施形態では、カバー部材60の固定部65は筐体2の他端側に設けられた装着部72に固定されるとして説明したが、固定部65は筐体2の受け部71よりも筐体2の他端寄りに固定されていればよく、装着部72は図示した位置に形成されなくてもよい。 Further, in the above-described embodiment, the fixing portion 65 of the cover member 60 has been described as being fixed to the mounting portion 72 provided on the other end side of the housing 2, but the fixing portion 65 is the receiving portion 71 of the housing 2. The mounting portion 72 may not be formed at the position shown in the drawing, as long as it is fixed closer to the other end of the housing 2.

また、上記した実施形態では、カバー部材60は筐体2に装着されるとして説明したが、これに限らず、グローブ50に装着されてもよい。また、カバー部材60の一方が筐体2に、他方がグローブ50に、それぞれ装着されてもよい。 Further, in the above-described embodiment, the cover member 60 has been described as being mounted on the housing 2, but the present invention is not limited to this, and the cover member 60 may be mounted on the glove 50. Further, one of the cover members 60 may be attached to the housing 2 and the other may be attached to the glove 50.

また、上記した実施形態では、グローブ50は必須の構成として説明したが、照明器具1はグローブ50を有さなくてもよい。かかる場合、カバー部材60はグローブ50が有する機能を備えることとなる。 Further, in the above-described embodiment, the glove 50 has been described as an indispensable configuration, but the lighting fixture 1 does not have to have the glove 50. In such a case, the cover member 60 will have the function of the glove 50.

実施形態に係る照明器具1は、筐体2、基板21、カバー部材60を具備する。筐体2は、一端側に受け部71を有する。基板21は、複数の発光素子22が実装されている。カバー部材60は、受け部71に引掛ける引掛部64と、固定部材を介して着脱可能に固定される固定部65とを有し、基板21を挟んで筐体2と向かい合うように配置される。これにより、カバー部材60の装着が容易となる。 The lighting fixture 1 according to the embodiment includes a housing 2, a substrate 21, and a cover member 60. The housing 2 has a receiving portion 71 on one end side. A plurality of light emitting elements 22 are mounted on the substrate 21. The cover member 60 has a hooking portion 64 that hooks on the receiving portion 71 and a fixing portion 65 that is detachably fixed via the fixing member, and is arranged so as to face the housing 2 with the substrate 21 interposed therebetween. .. This facilitates the mounting of the cover member 60.

また、実施形態に係る照明器具1は、筐体2の一端側に取付部6を有し、固定部65は、受け部71よりも筐体2の他端寄りに固定される。これにより、照明器具1が高所や屋外に設置された状態でのカバー部材60の着脱作業であっても、施工性が向上する。 Further, the lighting fixture 1 according to the embodiment has a mounting portion 6 on one end side of the housing 2, and the fixing portion 65 is fixed closer to the other end of the housing 2 than the receiving portion 71. As a result, the workability is improved even when the cover member 60 is attached / detached even when the lighting fixture 1 is installed in a high place or outdoors.
