Description

本発明は、光源ユニット及び照明器具に関し、更に詳しくは、実装基板、放熱部材及び取付部材を備える光源ユニット及びこの光源ユニットを備える照明器具に関する。 TECHNICAL FIELD The present invention relates to a light source unit and a lighting fixture, and more particularly to a light source unit including a mounting substrate, a heat radiating member and a mounting member, and a lighting fixture including the light source unit.

従来例として、特許文献1記載の照明器具を例示する。この従来例は、光源ユニット及び器具本体を備え、光源ユニットは、実装基板、放熱部材及び取付部材を備えている。取付部材の前面側に実装基板が設けられ、取付部材の後面側に放熱部材が設けられている。 As a conventional example, the lighting fixture described in Patent Document 1 will be exemplified.

しかしながら、特許文献1記載の従来例では、取付部材の前面が前方を向く状態では、LEDが発する光を斜め下方に効率良く照射することが難しい。また、光を斜め下方に効率良く照射するため、LEDの光軸を斜め下方に向けると、取付部材の前面が斜め下方を向くように取付部材を傾ける必要があるが、この場合、取付部材が占める空間の前後方向の長さが長くなってしまう。 However, in the conventional example described in Patent Document 1, it is difficult to efficiently irradiate the light emitted from the LED obliquely downward when the front surface of the mounting member faces forward. Also, in order to efficiently irradiate light obliquely downward, when the optical axis of the LED is directed obliquely downward, it is necessary to incline the mounting member so that the front surface of the mounting member faces obliquely downward. The length of the space occupied in the front-rear direction becomes long.

本開示は、取付部材が占める空間の前後方向の長さが長くなることを抑えつつ、光を斜め下方に効率良く照射することができる光源ユニット及び照明器具を提供することを目的とする。 An object of the present disclosure is to provide a light source unit and a lighting fixture that can efficiently irradiate light obliquely downward while suppressing an increase in the length of the space occupied by the mounting member in the front-rear direction.

本開示に係る一形態の光源ユニットは、固体発光素子を有する実装基板と、放熱部材と、前記実装基板及び前記放熱部材が取り付けられる取付部材と、を備える。前記取付部材の中心を通る一軸線の長手方向の一方を前方とすると共に他方を後方とし、前後方向と直交する方向の一方を上方とすると共に他方を下方とする。前記光源ユニットは、前記取付部材の前面に、前記実装基板が取り付けられる台座部を有する。前記光源ユニットは、前記取付部材の後面に前記放熱部材を有する。前記台座部の前記実装基板が取り付けられる基板取付面の法線ベクトルの向きを取付面向きとしたとき、前記取付面向きが前方に対して下方に傾いている。 A light source unit according to one aspect of the present disclosure includes a mounting substrate having a solid light emitting device, a heat dissipation member, and a mounting member to which the mounting substrate and the heat dissipation member are attached. One of the longitudinal directions of one axis passing through the center of the mounting member is defined as the front and the other is defined as the rear, and one of the directions orthogonal to the front-rear direction is defined as the upper and the other is defined as the lower. The light source unit has a pedestal on which the mounting board is attached on the front surface of the attachment member. The light source unit has the heat dissipation member on the rear surface of the mounting member. When the direction of the normal vector of the board mounting surface of the pedestal portion to which the mounting board is mounted is defined as the direction of the mounting surface, the direction of the mounting surface is inclined downward with respect to the front.

本開示に係る一形態の照明器具は、前記光源ユニットと、前記光源ユニットが取り付けられる器具本体と、を備える。 A lighting fixture according to one aspect of the present disclosure includes the light source unit and a fixture body to which the light source unit is attached.

本開示の光源ユニット及び照明器具にあっては、取付部材が占める空間の前後方向の長さが長くなることを抑えつつ、光を斜め下方に効率良く照射することができる。 In the light source unit and lighting fixture of the present disclosure, it is possible to efficiently irradiate light obliquely downward while suppressing an increase in the length of the space occupied by the mounting member in the front-rear direction.

以下、本開示に係る光源ユニット10及び照明器具1の一実施形態について、図1~図8に基いて説明する。図1に照明器具1の斜視図を示し、図2に照明器具1の一部を除く分解斜視図を示す。 An embodiment of a light source unit 10 and a lighting fixture 1 according to the present disclosure will be described below with reference to FIGS. 1 to 8. FIG. FIG. 1 shows a perspective view of the lighting fixture 1, and FIG. 2 shows an exploded perspective view of the lighting fixture 1 with a part removed.

まず、本実施形態の光源ユニット10について説明する。光源ユニット10は、図2に示すように、LEDモジュール2と、取付部材3と、放熱部材5と、反射板ブロック6と、カバーブロック7と、を備える。 First, the light source unit 10 of this embodiment will be described. The light source unit 10 includes an LED module 2, a mounting member 3, a heat dissipation member 5, a reflector block 6, and a cover block 7, as shown in FIG.

ここで、光源ユニット10及び照明器具1における上下方向、左右方向及び前後方向を規定する。図2に示すように、取付部材3の中心(特に図示せず)を通る一軸線の長手方向の一方を前方Fとすると共に、他方を後方Bとする。更に、前後方向と直交する方向の一方を上方Uとすると共に、他方を下方Dとする。更に、前後方向及び上下方向と直交する方向の一方を左方Lとすると共に、他方を右方Rとする。図2に示す上下方向、左右方向及び前後方向は、照明器具1の標準的な使用状態における上下方向、左右方向及び前後方向である。 Here, the up-down direction, left-right direction, and front-rear direction of the light source unit 10 and the lighting fixture 1 are defined. As shown in FIG. 2, one of the longitudinal directions of a single axis passing through the center (not shown) of the mounting member 3 is defined as the front F, and the other is defined as the rear B. As shown in FIG. Further, one of the directions perpendicular to the front-rear direction is referred to as upward U, and the other is referred to as downward D.

LEDモジュール2は、図3に示すように、固体発光素子としてのLED21(light Emitting Diode、発光ダイオード)と、実装基板20とを有する。LED21は、従来周知であるパッケージ型の白色LEDである。実装基板20は、左右方向を長手方向とする矩形状のアルミニウムからなる基板で構成される。LED21は、実装基板20の前面に、左右方向に複数(図示例では6個)並べて実装される。LED21の光軸の向き23は、実装基板20の前面の法線ベクトルの向きと一致する。LED21は、光軸の向き23に発せられる光の輝度が最も高く、発せられる光の向きが光軸の向き23から傾くに従って、光の輝度が低下していく。 The LED module 2 has an LED 21 (light emitting diode) as a solid light emitting element and a mounting substrate 20, as shown in FIG. The LED 21 is a conventionally well-known packaged white LED. The mounting board 20 is formed of a board made of aluminum and having a rectangular shape whose longitudinal direction is the left-right direction. A plurality of LEDs 21 (six in the illustrated example) are mounted side by side on the front surface of the mounting substrate 20 in the horizontal direction. The direction 23 of the optical axis of the LED 21 matches the direction of the normal vector on the front surface of the mounting board 20 . The brightness of the light emitted from the LED 21 is the highest in the direction 23 of the optical axis, and the brightness of the light decreases as the direction of the emitted light inclines from the direction 23 of the optical axis.

また、実装基板20の前面に、2個のレセプタクルコネクタ22が実装される。これら2つのレセプタクルコネクタ22は、実装基板20の前面に形成される配線用の導体(不図示)を介して、各LED21の電極(カソード及びアノード)と接続される。実装基板20は、取付部材3に取り付けられる。 Also, two receptacle connectors 22 are mounted on the front surface of the mounting board 20 . These two receptacle connectors 22 are connected to the electrodes (cathode and anode) of each LED 21 via wiring conductors (not shown) formed on the front surface of the mounting board 20 . The mounting board 20 is attached to the attachment member 3 .

図2に示すように、取付部材3は、取付枠31と、取付枠31の内部に固定される取付板30と、を有する。 As shown in FIG. 2 , the mounting member 3 has a mounting frame 31 and a mounting plate 30 fixed inside the mounting frame 31 .

図5に示すように、取付枠31は、アルミダイキャスト製品等、金属により形成されるが、PBT(Polybutylene terephthalate)樹脂などの透光性を有しない合成樹脂材料により形成されてもよい。取付枠31は、正面視矩形状をしており、内部に取付板30が配置される開口32を有する。取付枠31は、上下方向の中央部に左右方向に掛け渡される横架橋部33を有し、横架橋部33の上側に上開口321が位置し、横架橋部33の下側に下開口322が位置する。更に、取付枠31は、上開口321の左右方向の中央部に上下方向に掛け渡される縦架橋部34を有し、縦架橋部34の左側に上左開口3211が位置し、縦架橋部34の右側に上右開口3212が位置する。同様に、取付枠31は、下開口322の左右方向の中央部に上下方向に掛け渡される縦架橋部34を有し、縦架橋部34の左側に下左開口3221が位置し、縦架橋部34の右側に下右開口3222が位置する。上左開口3211、上右開口3212、下左開口3221及び下右開口3222は同じ大きさで、配置される取付板30は同じであり、特に区別されない。図2は、上左開口3211に配置される取付板30のみが取り外されている状態を示す。 As shown in FIG. 5, the mounting frame 31 is made of metal such as an aluminum die-cast product, but may be made of a non-translucent synthetic resin material such as PBT (polybutylene terephthalate) resin. The mounting frame 31 has a rectangular shape when viewed from the front, and has an opening 32 in which the mounting plate 30 is arranged. The mounting frame 31 has a horizontal bridge portion 33 that spans in the horizontal direction at the center portion in the vertical direction. is located. Further, the mounting frame 31 has a vertical bridge portion 34 that spans over the vertical center portion of the upper opening 321 in the horizontal direction. An upper right opening 3212 is located on the right side of the . Similarly, the mounting frame 31 has a vertical bridge portion 34 that spans over the vertical center portion of the lower opening 322 in the horizontal direction. A lower right opening 3222 is located to the right of 34 . The upper left opening 3211, the upper right opening 3212, the lower left opening 3221, and the lower right opening 3222 have the same size, and the mounting plates 30 arranged thereon are the same, so they are not particularly distinguished. FIG. 2 shows a state in which only the mounting plate 30 arranged in the upper left opening 3211 is removed.

図3に示すように、取付板30は、アルミダイキャスト製品等、金属により形成されるが、PBT樹脂などの透光性を有しない合成樹脂材料により形成されてもよい。取付板30は、正面視矩形状をしている。取付板30の前面は、前方Fを向いている。言い換えると、取付板30の前面の法線ベクトルの向き300は、前方F向きである。取付板30には、前後に貫通するいわゆるばか孔からなる貫通孔301が複数(図示例では10個)形成されている。取付板30は、取付枠31の上左開口3211に配置され、複数のビスからなる固着具371(図示例では10個)がそれぞれ貫通孔301に通されて、取付枠31に形成された雌ねじを有する固着孔(不図示)にねじ込まれる。これにより、取付板30が、取付枠31の上左開口3211に位置する状態で取付枠31に取り付けられる。取付枠31の上右開口3212、下左開口3221及び下右開口3222に位置する取付板30も同様にして取り付けられる。 As shown in FIG. 3, the mounting plate 30 is made of metal such as an aluminum die-cast product, but may be made of a non-translucent synthetic resin material such as PBT resin. The mounting plate 30 has a rectangular shape when viewed from the front. The front surface of the mounting plate 30 faces forward F. In other words, the orientation 300 of the normal vector of the front surface of the mounting plate 30 is the forward F orientation. The mounting plate 30 is formed with a plurality (10 in the illustrated example) of through holes 301 which are so-called clearance holes penetrating back and forth. The mounting plate 30 is arranged in the upper left opening 3211 of the mounting frame 31 , and the fasteners 371 (10 pieces in the illustrated example) made up of a plurality of screws are passed through the through holes 301 , respectively, to form female threads formed in the mounting frame 31 . (not shown). As a result, the mounting plate 30 is attached to the mounting frame 31 while being positioned in the upper left opening 3211 of the mounting frame 31 . The mounting plate 30 positioned at the upper right opening 3212, the lower left opening 3221, and the lower right opening 3222 of the mounting frame 31 is also attached in the same manner.

取付板30(取付部材3)は、前面に、実装基板20が取り付けられる台座部4を有する。台座部4は、取付板30と一体に形成されている。取付枠31、取付板30及び台座部4が、取付部材3を構成している。取付板30の前面(ただし台座部4が位置しない部分)が、取付部材3の前面を構成する。 The mounting plate 30 (mounting member 3) has a pedestal portion 4 on the front surface to which the mounting board 20 is mounted. The pedestal portion 4 is formed integrally with the mounting plate 30 . The mounting frame 31 , the mounting plate 30 and the base portion 4 constitute the mounting member 3 . The front surface of the mounting plate 30 (where the pedestal portion 4 is not located) constitutes the front surface of the mounting member 3 .

光源ユニット10は、複数の実装基板20と、複数の実装基板20にそれぞれ対応する複数の台座部4と、を備えている。更に説明すると、取付板30(取付部材3)は、複数(図示例では5個)の台座部4を有している。複数の台座部4は、取付板30の前面に上下に沿って並ぶように配置されている。 The light source unit 10 includes a plurality of mounting substrates 20 and a plurality of pedestals 4 respectively corresponding to the plurality of mounting substrates 20 . More specifically, the mounting plate 30 (mounting member 3 ) has a plurality of (five in the illustrated example) pedestal portions 4 . The plurality of pedestals 4 are arranged vertically on the front surface of the mounting plate 30 .

台座部4の前面は、実装基板20の後面が取り付けられる基板取付面40となる。基板取付面40の形状は、実装基板20の形状と概ね同じに形成されている。基板取付面40の大きさは、実装基板20の大きさよりも若干大きく形成されている。本実施形態では、実装基板20は、押さえ部材35及び熱伝導シート36とともに台座部4に取り付けられる。 The front surface of the pedestal portion 4 serves as a board mounting surface 40 to which the rear surface of the mounting board 20 is mounted. The shape of the board mounting surface 40 is formed substantially the same as the shape of the mounting board 20 . The size of the board mounting surface 40 is slightly larger than the size of the mounting board 20 . In this embodiment, the mounting board 20 is attached to the base portion 4 together with the pressing member 35 and the heat conductive sheet 36 .

押さえ部材35は、PBT樹脂などの透光性を有しない合成樹脂材料により形成される、板状の部材である。押さえ部材35の形状は、実装基板20の形状と概ね同じに形成されている。押さえ部材35の大きさは、実装基板20の大きさよりも若干大きく、基板取付面40の大きさと略同じに形成されている。押さえ部材35には、実装基板20の各LED21に対応する位置にそれぞれ、LED21が発する光を透過させる透過窓351が形成されている。押さえ部材35には、透過窓351と異なる位置に、いわゆるばか孔からなり、複数(図示例では5個)のビスからなる固着具372がそれぞれ通される複数(図示例では5個)の貫通孔352が形成されている。 The pressing member 35 is a plate-like member made of a non-translucent synthetic resin material such as PBT resin. The shape of the pressing member 35 is formed substantially the same as the shape of the mounting board 20 . The size of the pressing member 35 is slightly larger than the size of the mounting board 20 and substantially the same as the size of the board mounting surface 40 . Transmission windows 351 are formed in the holding member 35 at positions corresponding to the respective LEDs 21 on the mounting board 20 , through which the light emitted by the LEDs 21 is transmitted. The pressing member 35 has a so-called clearance hole at a position different from the transmission window 351, and a plurality of (five in the illustrated example) through-holes through which fasteners 372 each consisting of a plurality of (five in the illustrated example) screws are passed. A hole 352 is formed.

熱伝導シート36は、電気絶縁性と熱伝導性に優れた材料(例えば、シリコーン樹脂)により形成される、板状の部材である。熱伝導シート36の形状は、実装基板20の形状と概ね同じに形成されている。熱伝導シート36の大きさは、実装基板20の大きさよりも若干大きく、基板取付面40の大きさと略同じに形成されている。 The thermally conductive sheet 36 is a plate-shaped member made of a material (for example, silicone resin) with excellent electrical insulation and thermal conductivity. The shape of the heat conductive sheet 36 is formed substantially the same as the shape of the mounting board 20 . The size of the heat conductive sheet 36 is slightly larger than the size of the mounting board 20 and is formed to be substantially the same as the size of the board mounting surface 40 .

実装基板20及び熱伝導シート36には、押さえ部材35の貫通孔352に対応する位置にそれぞれ、固着具372を避けるための切欠201,361が形成されている。また、台座部4には、押さえ部材35の貫通孔352に対応する位置にそれぞれ、固着具372がねじ込まれる雌ねじを有する固着孔41が形成されている。 Notches 201 and 361 are formed in the mounting board 20 and the thermally conductive sheet 36 at positions corresponding to the through holes 352 of the pressing member 35 to avoid the fasteners 372 . Further, fixing holes 41 having internal threads into which fixing tools 372 are screwed are formed in the base portion 4 at positions corresponding to the through holes 352 of the pressing member 35 .

実装基板20、押さえ部材35及び熱伝導シート36は、台座部4の基板取付面40に近い側から熱伝導シート36、実装基板20及び押さえ部材35の順に重ねられる。固着具372が、前方F側より押さえ部材35の貫通孔352、実装基板20の切欠201及び熱伝導シート36の切欠361に通されて、台座部4の固着孔41にねじ込まれて、実装基板20、押さえ部材35及び熱伝導シート36が台座部4に取り付けられる。これにより、実装基板20、熱伝導シート36及び台座部4は熱的に連結される。 The mounting board 20 , the pressing member 35 and the thermally conductive sheet 36 are stacked in the order of the thermally conductive sheet 36 , the mounting board 20 and the pressing member 35 from the side closer to the board mounting surface 40 of the pedestal portion 4 . The fastener 372 is passed from the front side F through the through hole 352 of the pressing member 35, the notch 201 of the mounting board 20 and the notch 361 of the thermally conductive sheet 36, and is screwed into the fixing hole 41 of the pedestal 4 to attach the mounting board. 20 , a pressing member 35 and a heat conductive sheet 36 are attached to the base portion 4 . As a result, the mounting substrate 20, the heat conductive sheet 36, and the pedestal portion 4 are thermally connected.

図4に示すように、基板取付面40の法線ベクトルの向きを取付面向き42としたとき、取付面向き42は、前方Fに対して下方Dに角度θ1で傾いている。角度θ1は、少なくとも、0度より大きくかつ90度より小さい。好ましくは、角度θ1は、30度以上かつ60度以下であり、図示例では45度である。 As shown in FIG. 4, when the direction of the normal vector of the substrate mounting surface 40 is defined as the mounting surface direction 42, the mounting surface direction 42 is inclined downward D with respect to the front F at an angle θ1. Angle θ1 is at least greater than 0 degrees and less than 90 degrees. Preferably, the angle θ1 is 30 degrees or more and 60 degrees or less, and is 45 degrees in the illustrated example.

台座部4の基板取付面40に取り付けられている実装基板20のLED21の光軸の向き23が前方Fに対して下方Dに傾く角度θ2は、取付面向き42が前方Fに対して下方Dに傾く角度θ1と同じである。従って、角度θ2は、角度θ1と同様に、少なくとも、0度より大きくかつ90度より小さい。好ましくは、角度θ2は、30度以上かつ60度以下であり、図示例では45度である。 The angle θ2 at which the optical axis direction 23 of the LED 21 of the mounting board 20 attached to the board mounting surface 40 of the pedestal 4 is inclined downward D with respect to the front F is such that the mounting surface direction 42 is downward D with respect to the front F. is the same as the angle θ1 inclined to Accordingly, the angle θ2 is at least greater than 0 degrees and less than 90 degrees, as is the angle θ1. Preferably, the angle θ2 is 30 degrees or more and 60 degrees or less, and is 45 degrees in the illustrated example.

本実施形態では、複数の台座部4の取付面向き42の前方Fに対して傾く角度θ1は全て同じであるが、台座部4によって角度θ1が異なってもよい。また、LED21の光軸の向き23が前方Fに対して下方Dに傾く角度θ2は全て同じであるが、LED21によって角度θ2が異なってもよい。 In this embodiment, the angles θ1 at which the mounting surface orientations 42 of the plurality of pedestals 4 are inclined with respect to the front F are all the same, but the angles θ1 may differ depending on the pedestals 4 . Further, the angles θ2 at which the directions 23 of the optical axes of the LEDs 21 incline downward D with respect to the front F are all the same, but the angles θ2 may differ depending on the LEDs 21 .

これにより、取付部材3の前面が前方Fを向いたままで、取付部材3が占める空間の前後方向の長さが短い状態のまま、光を斜め下方に効率良く照射することができる。 As a result, the front surface of the mounting member 3 faces forward F, and the space occupied by the mounting member 3 is kept short in the front-rear direction, and light can be emitted obliquely downward efficiently.

また、角度θ1及び角度θ2が30度以上かつ60度以下であるため、前方Fに対して下方Dに30度以上かつ60度以下の角度で傾く方向に光を効率良く照射することができる。 In addition, since the angles θ1 and θ2 are 30 degrees or more and 60 degrees or less, the light can be efficiently emitted in a direction inclined downward D with respect to the front F by an angle of 30 degrees or more and 60 degrees or less.

図5に示すように、放熱部材5は、取付部材3の後面に取り付けられる。放熱部材5は、取付基板51、放熱板53及びパイプ55を有する。取付基板51は、アルミニウムからなり、正面視矩形状をしている。取付基板51には、複数の放熱板53が取り付けられる。放熱板53は、アルミニウムからなり、側面視矩形状をしている。放熱板53は、取付基板51に溶接により取り付けられる。また、取付基板51及び放熱板53には、冷却水を通すパイプ55が通されている。パイプ55は、取付基板51に形成された溝52に嵌まると共に、放熱板53に形成された貫通孔54を通る状態で、配置される。 As shown in FIG. 5 , the heat radiating member 5 is attached to the rear surface of the mounting member 3 . The heat dissipation member 5 has a mounting substrate 51 , a heat dissipation plate 53 and a pipe 55 . The mounting substrate 51 is made of aluminum and has a rectangular shape when viewed from the front. A plurality of heat sinks 53 are attached to the mounting substrate 51 . The radiator plate 53 is made of aluminum and has a rectangular shape when viewed from the side. The radiator plate 53 is attached to the mounting substrate 51 by welding. A pipe 55 through which cooling water passes is passed through the mounting substrate 51 and the radiator plate 53 . The pipe 55 is arranged so as to fit in the groove 52 formed in the mounting substrate 51 and to pass through the through hole 54 formed in the radiator plate 53 .

放熱部材5は、押さえ枠11により押さえられて、取付部材3に取り付けられる。押さえ枠11は、合成樹脂からなり、正面視矩形状をしている。押さえ枠11は、押さえ枠固定部材12により押さえられて、取付部材3に取り付けられる。押さえ枠固定部材12は、鋼板からなるが、他の金属、あるいは合成樹脂等からなるものであってもよい。押さえ枠固定部材12は、貫通孔121を有している。また、取付枠31の後面には、雌ねじを有する固着孔311が形成されている。 The heat radiating member 5 is attached to the attachment member 3 while being pressed by the pressing frame 11 . The holding frame 11 is made of synthetic resin and has a rectangular shape when viewed from the front. The holding frame 11 is held by the holding frame fixing member 12 and attached to the mounting member 3 .

A fastener 131 made of a screw is passed through the through-hole 121 of the presser frame fixing member 12 from the rear B side and screwed into the fixing hole 311 of the mounting frame 31 to attach the heat radiating member 5 to the mounting member 3 . Thereby, the heat radiating member 5 and the mounting member 3 are thermally connected.

反射板ブロック6は、図6A~図7Bに示すように、合成樹脂からなり、枠部60及び反射板61を有する。反射板61のうちの上反射板611は、図8に示すように、LED21を起点として前方Fよりも上方U側の領域に配置され、この領域を覆う。上反射板611は、左右方向から見て下方Dを向く凹面からなる上反射面62を有する。上反射面62は鏡面である。このような上反射面62を有する上反射板611が配置されることにより、LED21から発せられた光が前方Fよりも上方U側に向かうのが抑えられる。 The reflector block 6 is made of synthetic resin and has a frame portion 60 and a reflector 61, as shown in FIGS. 6A to 7B. As shown in FIG. 8, the upper reflector 611 of the reflectors 61 is arranged in an area on the upper U side of the front F with the LED 21 as a starting point, and covers this area. The upper reflecting plate 611 has an upper reflecting surface 62 which is a concave surface facing downward D when viewed in the left-right direction. The upper reflecting surface 62 is a mirror surface. By arranging the upper reflecting plate 611 having such an upper reflecting surface 62, the light emitted from the LED 21 is prevented from going upwards rather than forwards F.

本実施形態では、LED21を起点として上反射面62の前方F側の端部に至る向きは、前方Fに対して下方Dに角度θ3で傾いている。このため、LED21から発せられた光は、前方Fに対して下方Dに角度θ3の向きよりも上方U側に向かうのが抑えられる。角度θ3は、0度以上でかつ45度以下である。好ましくは、角度θ3は、10度である。 In the present embodiment, the direction from the LED 21 to the end of the upper reflective surface 62 on the front side F is inclined downward D with respect to the front side F at an angle θ3. For this reason, the light emitted from the LED 21 is suppressed from going downward D with respect to the front F and upward U rather than in the direction of the angle θ3. The angle θ3 is 0 degrees or more and 45 degrees or less. Preferably, the angle θ3 is 10 degrees.

また、上反射面62の前方F側の端部における上反射面62に沿う向きは、前方Fに対して下方Dに角度θ5で傾いている。角度θ5は、30度以上でかつ40度以下で、好ましくは34.2度である。 Further, the direction along the upper reflecting surface 62 at the end portion of the upper reflecting surface 62 on the front F side is inclined downward D with respect to the front F at an angle θ5. The angle θ5 is 30 degrees or more and 40 degrees or less, preferably 34.2 degrees.

また、反射板61のうちの下反射板612は、図8に示すように、LED21を起点として前方Fよりも下方D側の領域に配置され、この領域を覆う。下反射板612は、複数のLED21毎に、LED21を起点として前方Fよりも下方D側の領域に配置される下反射面63を有する。下反射面63は鏡面である。下反射面63は、図6Aに示すように、LED21毎に、前後方向から見て上方Uを向く凹面からなる。本実施形態では、LED21を起点として下反射面63の前方F側の端部に至る向きは、前方Fに対して下方Dに角度θ4(図8参照)で傾いている。角度θ4は角度θ3より大きい。角度θ4は、30度以上でかつ90度以下である。好ましくは、角度θ4は、34度である。 Moreover, as shown in FIG. 8, the lower reflector 612 of the reflector 61 is arranged in a region on the lower side D than the front F with the LED 21 as a starting point, and covers this region. The lower reflecting plate 612 has a lower reflecting surface 63 arranged in a region on the lower side D than the front side F with the LED 21 as a starting point for each of the plurality of LEDs 21 . The lower reflecting surface 63 is a mirror surface. As shown in FIG. 6A, the lower reflecting surface 63 is a concave surface facing upward U when viewed from the front-rear direction for each LED 21 . In the present embodiment, the direction from the LED 21 to the end of the lower reflecting surface 63 on the front side F is inclined downward D with respect to the front side F at an angle θ4 (see FIG. 8). Angle θ4 is greater than angle θ3. The angle θ4 is 30 degrees or more and 90 degrees or less. Preferably, the angle θ4 is 34 degrees.

このような下反射面63により、LED21から発せられた光は、前方Fに対して下方Dに角度θ4の向きよりも下方D側に向かうのが抑えられる。これにより、少なくとも直接LED21から発せられた光は、前方Fに対して下方Dに傾く角度θ4と角度θ3との間の角度で(例えば10度以上でかつ34度以下の角度で)照射される。 With such a lower reflecting surface 63, the light emitted from the LED 21 is suppressed from going downward D with respect to the forward direction F, rather than toward the angle θ4. As a result, at least the light directly emitted from the LED 21 is irradiated at an angle between the angle θ4 and the angle θ3 that is inclined downward D with respect to the front F (for example, at an angle of 10 degrees or more and 34 degrees or less). .

また、LED21から前方Fに対して下方Dに角度θ3の向きよりも上方U側に向かうように発せられた光は、上反射面62で反射して下方Dに向かうため、無駄にならずロスが生じにくい。 In addition, the light emitted from the LED 21 toward the upward U side rather than downward D with respect to the forward direction F at the angle θ3 is reflected by the upper reflecting surface 62 and directed downward D, so that the light is not wasted and is lost. is less likely to occur.

また、反射板61は、隣接するLED21の間に仕切壁64を有する。仕切壁64は、下反射板612から上方に向けて起立しており、下反射面63とつながっている。仕切壁64の左右方向における側面641は、下反射面63となる凹面と滑らかにつながる凹面を有する。すなわち、下反射面63は、前後方向から見て上方Uを向く凹面からなり、側面641は下反射面63の凹面に滑らかに(尖った部分がなく)つながり、上方U及び前後方向から見て左右方向における内方を向く凹面からなる。 Moreover, the reflector 61 has a partition wall 64 between adjacent LEDs 21 . The partition wall 64 rises upward from the lower reflecting plate 612 and is connected to the lower reflecting surface 63 . A side surface 641 in the left-right direction of the partition wall 64 has a concave surface that smoothly connects with the concave surface serving as the lower reflecting surface 63 . That is, the lower reflecting surface 63 is formed of a concave surface facing upward U when viewed from the front-rear direction, and the side surface 641 is smoothly connected to the concave surface of the lower reflecting surface 63 (without sharp portions), and is It consists of concave surfaces facing inward in the left-right direction.

反射板61が仕切壁64を有することにより、LED21から発せられ、前方Fに対して左右方向の外側に傾いた方向に向かう光が、仕切壁64で、左右方向において前方Fに近い方を向くように内側に反射される。これにより、LED21から発せられた光がより多く光軸の向き23に近い向きに照射される。 Since the reflector 61 has the partition wall 64, light emitted from the LED 21 and directed in a direction inclined outward in the left-right direction with respect to the front F is directed toward the front F in the left-right direction by the partition wall 64. are reflected inward. As a result, more light emitted from the LED 21 is emitted in a direction closer to the direction 23 of the optical axis.

また、仕切壁64が下反射面63とつながっているため、LED21から発せられた光が仕切壁64と下反射面63との間から漏れることがなく、光の照射の効率が低下するのを抑えることができる。 Moreover, since the partition wall 64 is connected to the lower reflective surface 63, the light emitted from the LED 21 does not leak from between the partition wall 64 and the lower reflective surface 63, thereby preventing the light irradiation efficiency from being lowered. can be suppressed.

また、側面641が下反射面63となる凹面と滑らかにつながる凹面を有するため、側面641で反射された光が、下反射面63で反射された光と滑らかにつながり、光の分布の変化が滑らかとなる。 In addition, since the side surface 641 has a concave surface that smoothly connects with the concave surface that serves as the lower reflecting surface 63, the light reflected by the side surface 641 smoothly connects with the light reflected by the lower reflecting surface 63, and the change in light distribution is reduced. become smooth.

また、上反射面62が左右方向から見て下方Dを向く凹面からなるため、LED21から発せられ上反射面62で反射した光は、大きく下方Dに向かうのが抑えられ、前方Fに対して下方Dに傾く角度θ4と角度θ3との間の角度で照射されやすくなる。 In addition, since the upper reflecting surface 62 is a concave surface that faces downward D when viewed from the left and right direction, the light emitted from the LED 21 and reflected by the upper reflecting surface 62 is suppressed from traveling largely downward D. It becomes easier to irradiate at an angle between the angle θ4 and the angle θ3 that inclines downward D.

また、LED21から前方Fに対して下方Dに角度θ4の向きよりも下方D側に向かうように発せられた光は、下反射面63で反射して上方Uに向かうため、無駄にならずロスが生じにくい。また、下反射面63が、LED21毎に、前後方向から見て上方Uを向く凹面からなるため、LED21から発せられ、前方Fに対して左右方向に傾いた方向に向かう光が、下反射面63で、左右方向において前方Fに近づくように反射される。 Further, the light emitted from the LED 21 toward the downward direction D from the forward direction F toward the downward direction D rather than the direction of the angle θ4 is reflected by the lower reflecting surface 63 and directed upward U. is less likely to occur. In addition, since the lower reflecting surface 63 is formed of a concave surface facing upward U when viewed from the front-rear direction, the light emitted from the LED 21 and directed in a direction inclined in the left-right direction with respect to the front F is reflected by the lower reflecting surface 63 . At 63, it is reflected closer to the front F in the left and right direction.

枠部60は、図6Aに示すように、各LEDモジュール2毎に配置される上反射板611及び下反射板612をまとめてユニット化している。枠部60には、ビスからなる固着具132(図2参照)が通される切欠601が形成されている。 As shown in FIG. 6A, the frame portion 60 unitizes an upper reflecting plate 611 and a lower reflecting plate 612 arranged for each LED module 2 .
