Further, when the luminaire 11 shown in FIG. 3 or the like is attached to the attached portion C and the direction orthogonal to the attached portion C is the vertical direction of the luminaire 11, the attachment surface side of the luminaire 11 is upward. The direction directly below the irradiation surface side of the luminaire 11 will be described as downward. The direction orthogonal to the vertical direction of the luminaire 11 will be described as the side of the luminaire 11. Further, in the following description, a state in which the luminaire 11 and the like are viewed from below is defined as a plan view. The state in which the luminaire 11 or the like is viewed from a direction orthogonal to the vertical direction is defined as a side view.

It mainly includes 81, a mounting member 91, a terminal block 100, and a sensor unit 101. The outer shape of the luminaire 11 has a substantially circular shape in a plan view, and the height direction of the luminaire 11 (vertical direction of the luminaire 11 in FIG. 3) is the radial direction of the luminaire 11 (illumination in FIG. 3). It has a substantially cylindrical shape that is thin and flat, smaller than the dimension (direction orthogonal to the vertical direction) of the appliance 11.
The outer shape of the luminaire 11 is not limited to this embodiment. The outer shape of the luminaire 11 may be, for example, an elliptical shape, a square shape, a rectangular shape, a polygonal shape, a fan shape, or a combination thereof, in addition to the substantially circular shape in a plan view.

器具本体21は、電源部31、光源部(LEDモジュール)41、導光部材51、反射部材61、環状反射部材71、光源セット部81、端子台100、センサ部101を保持するともに取付部材91に取り付けられる部材である。器具本体21は、導光部材51を露出するための開口を下側に有するとともに上端が開放された略円筒状部材である。器具本体21は、円筒部22と、円筒部22の下端部から径方向内側に延出される円環状の内縁部23と、を有している。器具本体21は、熱伝導率の高い、例えば金属素材で構成される。本実施形態では一例として器具本体21をアルミニウム合金で構成し、電源部31および光源部41から生ずる熱を放熱することができる。器具本体21は、その最大内径寸法が取付部材91の外径寸法よりも大きく、取付部材91の照射面側に取り付け可能である。器具本体21は、円筒部22の内周面に側面視四角形状で凸状の複数(本実施形態では3つ)の位置決め部22aと、各位置決め部22aに対応して円筒部22の上端部に設けられる側面視略長方形状で凸状の複数(本実施形態では3つ)の係止部22bと、各位置決め部22aに対応して円筒部22の下端部に設けられる側面視略長方形状で凸状の複数(本実施形態では3つ)の下端凸部22cと、を有している。位置決め部22a、係止部22b及び下端凸部22cは、円筒部22の内周面において周方向に沿って略等間隔で形成されている。位置決め部22aの上端部は、取付部材91に器具本体21を取り付ける際に、取付部材91の被係止部94(案内部94b)の下端部の位置を規制するものである。位置決め部22aの下端部は、器具本体21に光源セット部81を取り付ける際に、光源セット部81(光源部41)の上端部の位置を規制するものである。これにより、光源セット部81(光源部41)を器具本体21の底部の所定の位置に保持することができる。 The instrument body 21 holds the power supply unit 31, the light source unit (LED module) 41, the light guide member 51, the reflection member 61, the annular reflection member 71, the light source set unit 81, the terminal block 100, and the sensor unit 101, and also holds the mounting member 91. It is a member that can be attached to. The instrument main body 21 is a substantially cylindrical member having an opening for exposing the light guide member 51 on the lower side and having an open upper end. The instrument body 21 has a cylindrical portion 22 and an annular inner edge portion 23 extending radially inward from the lower end portion of the cylindrical portion 22. The instrument body 21 is made of, for example, a metal material having high thermal conductivity. In the present embodiment, as an example, the appliance main body 21 is made of an aluminum alloy, and the heat generated from the power supply unit 31 and the light source unit 41 can be dissipated. The maximum inner diameter of the instrument body 21 is larger than the outer diameter of the mounting member 91, and the instrument body 21 can be mounted on the irradiation surface side of the mounting member 91. The instrument body 21 has a plurality of (three in this embodiment) positioning portions 22a having a rectangular shape and a convex shape on the inner peripheral surface of the cylindrical portion 22, and an upper end portion of the cylindrical portion 22 corresponding to each positioning portion 22a. A plurality of (three in this embodiment) locking portions 22b having a substantially rectangular shape and a convex shape in the side view, and a substantially rectangular shape in the side view provided at the lower end of the cylindrical portion 22 corresponding to each positioning portion 22a. It has a plurality of convex lower end convex portions 22c (three in the present embodiment). The positioning portion 22a, the locking portion 22b, and the lower end convex portion 22c are formed on the inner peripheral surface of the cylindrical portion 22 at substantially equal intervals along the circumferential direction. The upper end portion of the positioning portion 22a regulates the position of the lower end portion of the locked portion 94 (guide portion 94b) of the mounting member 91 when the appliance main body 21 is attached to the mounting member 91. The lower end portion of the positioning portion 22a regulates the position of the upper end portion of the light source setting portion 81 (light source portion 41) when the light source setting portion 81 is attached to the instrument main body 21. As a result, the light source setting unit 81 (light source unit 41) can be held at a predetermined position on the bottom of the instrument main body 21.

器具本体21の内縁部23は、導光部材51の照射面側の外周縁部と対向する。内縁部23は、平面視においてLED素子42の径方向内側の縁部と重なる反射部23aを有している。反射部23aは、器具本体21に環状反射部材71を組付けた際に、環状反射部材71の内周縁よりも径方向内側に延出される部分である。具体的には、反射部23aは、取付面側に反射面を有し、LED素子42から出射して導光部材51を透過した光を反射する部分である。また、反射部23aは、LED素子42の少なくとも一部と重なるように配置されることで、LED素子42が発する光の直接光を遮るため、ユーザーの目に直接LED素子42が発する光が達することを抑えることできる。これにより、照明光のムラを抑えるとともに、グレアを軽減した照明光を得ることができる。反射部23aは、導光部材51を器具本体21内に配置された環状反射部材71に組み付けた際に、導光部材51の照射面側の外周縁部に当接または近接する部分である。
なお、本実施形態では、反射部23aは、内縁部23と一体的な部材として構成しているが、例えば、反射部を別部材として構成し、内縁部に連設してもよい。
また、反射部23aには、例えば必要に応じて、周方向に沿って溝部を設けて、この溝部に沿って円環状のパッキンを配置してもよい。パッキンは、器具本体21(反射部23a)と導光部材51の隙間を覆うためのものであり、水滴や埃等が照明器具11の内部への侵入することを防ぐ、いわゆる気密パッキンとして作用する。
The inner edge portion 23 of the instrument main body 21 faces the outer peripheral edge portion of the light guide member 51 on the irradiation surface side. The inner edge portion 23 has a reflecting portion 23a that overlaps with the radial inner edge portion of the LED element 42 in a plan view. The reflecting portion 23a is a portion that extends radially inward from the inner peripheral edge of the annular reflecting member 71 when the annular reflecting member 71 is assembled to the instrument main body 21. Specifically, the reflecting portion 23a is a portion that has a reflecting surface on the mounting surface side and reflects light emitted from the LED element 42 and transmitted through the light guide member 51. Further, since the reflecting portion 23a is arranged so as to overlap at least a part of the LED element 42, the direct light of the light emitted by the LED element 42 is blocked, so that the light emitted by the LED element 42 directly reaches the user's eyes. It can be suppressed. As a result, it is possible to obtain illumination light with reduced glare while suppressing unevenness of the illumination light. The reflection portion 23a is a portion that comes into contact with or is close to the outer peripheral edge portion of the light guide member 51 on the irradiation surface side when the light guide member 51 is assembled to the annular reflection member 71 arranged in the instrument main body 21.
In the present embodiment, the reflecting portion 23a is configured as an integral member with the inner edge portion 23, but for example, the reflecting portion may be configured as a separate member and continuously provided at the inner edge portion.
Further, for example, the reflecting portion 23a may be provided with a groove portion along the circumferential direction, and an annular packing may be arranged along the groove portion, if necessary. The packing is for covering the gap between the fixture body 21 (reflecting portion 23a) and the light guide member 51, and acts as a so-called airtight packing that prevents water droplets, dust, etc. from entering the inside of the lighting fixture 11. ..

位置決め部22aの1つには、位置決め部22aの表面から径方向内側に突出するネジ固定部24が設けられている。ネジ固定部24は、電源カバー33のネジ取付部33bと光源セット部81のカバー取付部84とをネジ等の取付部材により共締めするための部分である。 One of the positioning portions 22a is provided with a screw fixing portion 24 protruding inward in the radial direction from the surface of the positioning portion 22a. The screw fixing portion 24 is a portion for jointly tightening the screw mounting portion 33b of the power supply cover 33 and the cover mounting portion 84 of the light source setting portion 81 with mounting members such as screws.

円筒部22の内周面には、上下方向に平行に並ぶ2列の突条部22d・22dが設けられている。突条部22dは、上面視において略三角形状であり、突条部22dは、円筒部22の下端部から上下方向に沿って円筒部22の上端近傍まで延設される。突条部22dは、器具本体21を取付部材91に取り付ける際に、後述する器具本体21の弾性係合部95が係合される被係合部分である。
なお、本実施形態では、突条部22dを2列設けているが、1列もしくは3列以上であってもよい。
Two rows of ridges 22d and 22d arranged in parallel in the vertical direction are provided on the inner peripheral surface of the cylindrical portion 22. The ridge portion 22d has a substantially triangular shape when viewed from above, and the ridge portion 22d extends from the lower end portion of the cylindrical portion 22 to the vicinity of the upper end portion of the cylindrical portion 22 along the vertical direction. The ridge portion 22d is an engaged portion to which the elastic engaging portion 95 of the instrument main body 21, which will be described later, is engaged when the instrument main body 21 is attached to the mounting member 91.
In the present embodiment, the protrusions 22d are provided in two rows, but the number of ridges 22d may be one row or three or more rows.

器具本体21は、内部の清掃や器具本体21の部品交換等のために、取付部材91に対して着脱できる構造となっている。
また、器具本体21の材質としては、アルミニウム合金以外であってもよく、例えばアルミニウム合金以外の金属素材、樹脂など必要に応じて適宜素材を選択することもできる。
The instrument body 21 has a structure that can be attached to and detached from the mounting member 91 for cleaning the inside and replacing parts of the instrument body 21.
Further, the material of the instrument main body 21 may be other than the aluminum alloy, and for example, a metal material other than the aluminum alloy, a resin, or the like can be appropriately selected as needed.

The power supply unit 31 is for converting an alternating current supplied from an external commercial power source into a predetermined direct current and supplying the converted current to a plurality of LED elements 42 mounted on the substrate 43.

電源部31は、配線(図示せず)を介して端子台100に電気的に接続されている。例えば、照明器具11を被取付部Cに取り付ける際、天井裏側の外部商用電源の電源電線(図示せず)を端子台100に接続することで、電源部31は外部商用電源と電気的に接続される。電源部31と光源部41は配線37によって電気的に接続されている。
なお、本実施形態では、端子台100を使用しているが、特に限定するものではない。例えば、端子台100を使用する代わりに、コネクタ等の接続部品を使用する構成とすることもできる。
The power supply unit 31 is electrically connected to the terminal block 100 via wiring (not shown). For example, when the lighting fixture 11 is attached to the attached portion C, the power supply portion 31 is electrically connected to the external commercial power source by connecting the power supply wire (not shown) of the external commercial power source on the back side of the ceiling to the terminal block 100. Will be done. The power supply unit 31 and the light source unit 41 are electrically connected by wiring 37.
Although the terminal block 100 is used in this embodiment, it is not particularly limited. For example, instead of using the terminal block 100, a connection component such as a connector may be used.

光源部41は、照明器具11の照射面側に向けて光を出射する部分である。光源部41は、光源である発光素子を有する光源モジュールである。本実施形態においては、発光素子として、基板43上に複数の光源であるLED(Light emitting diode)素子42が表面実装されたLED光源モジュールを使用している。具体的には、LED光源モジュールは、略円板状に加工された基板43表面に、複数のLED素子42が周方向に略等間隔に配列されたモジュールである。基板43には、外周縁部にセンサ部101のセンサ露出部105に対応する平面視略台形状の切欠き部45が設けられている。複数のLED素子42は、基板43の外周縁(切欠き部45を除く部分)の近傍に円環状の素子列として実装されている(図2参照)。切欠き部45aに最も近接するLED素子42aは、センサ部101と最も近接するように配置される。センサ部に最も近接するLED素子42aは、導光部材51の中心Eと結ぶ線が導光部材51の切欠き部54と重ならないように配置されている。なお、本実施形態では、導光部材51の中心Eは、導光部材51の切欠き部54を除く外周端の円弧の中心を用いている。導光部材51の中心Eは、その導光部材51の開口部(切欠き部)54を除く外形形状から設定することもできる。例えば、平面視多角形状の一部に開口部を有する導光部材の場合には、開口部を有さない仮想的な外形形状における重心などを導光部材の中心として採用することができる。光源部41は、基板43上に給電素子44を有している。給電素子44は、複数のLED素子42のうち二つのLED素子42の間に配置される。これにより、給電素子44を配置するスペースを基板43上に別途設ける必要がなく、基板43をコンパクトにすることができる。光源部41は、光源セット部81の照射面側に配置される。複数のLED素子42は、導光部材51の取付面側の外周端近傍に対向するように配置される。LED光源モジュールは、配線37によって電源部31と電気的に接続されている。LED光源モジュールは、基板43の実装面の裏面が光源セット部81の光源配置面82に当接して配置されるため、LED光源モジュールが発熱した際には、LED光源モジュールの熱が光源セット部81に伝わる。光源セット部81に伝わった熱は、光源セット部81の取付面側の周辺温度が光源セット部81の温度よりも低い場合、光源セット部81の取付面側の周辺の空気へ伝わる。また、光源セット部81に伝わった熱の一部は、器具本体21に伝わり、器具本体21の周辺温度が器具本体21の温度よりも低い場合、器具本体21の周辺の空気へ伝わる。これにより、光源セット部81に伝わった熱は、光源セット部81や器具本体21の周囲に放熱される。 The light source unit 41 is a portion that emits light toward the irradiation surface side of the luminaire 11. The light source unit 41 is a light source module having a light emitting element which is a light source. In the present embodiment, as the light emitting element, an LED light source module in which LED (Light emittering diode) elements 42, which are a plurality of light sources, are surface-mounted on the substrate 43 is used. Specifically, the LED light source module is a module in which a plurality of LED elements 42 are arranged at substantially equal intervals in the circumferential direction on the surface of a substrate 43 processed into a substantially disk shape. The substrate 43 is provided with a substantially trapezoidal notch 45 in a plan view corresponding to the exposed sensor 105 of the sensor 101 on the outer peripheral edge. The plurality of LED elements 42 are mounted as an annular element array in the vicinity of the outer peripheral edge (the portion excluding the notch 45) of the substrate 43 (see FIG. 2). The LED element 42a closest to the notch 45a is arranged so as to be closest to the sensor 101. The LED element 42a closest to the sensor unit is arranged so that the line connecting to the center E of the light guide member 51 does not overlap with the notch 54 of the light guide member 51. In the present embodiment, the center E of the light guide member 51 uses the center of the arc at the outer peripheral end excluding the notch 54 of the light guide member 51. The center E of the light guide member 51 can also be set from the outer shape excluding the opening (notch) 54 of the light guide member 51. For example, in the case of a light guide member having an opening in a part of a polygonal shape in a plan view, the center of gravity in a virtual outer shape having no opening can be adopted as the center of the light guide member. The light source unit 41 has a power feeding element 44 on the substrate 43. The power feeding element 44 is arranged between two LED elements 42 among the plurality of LED elements 42. As a result, it is not necessary to separately provide a space for arranging the power feeding element 44 on the substrate 43, and the substrate 43 can be made compact. The light source unit 41 is arranged on the irradiation surface side of the light source setting unit 81. The plurality of LED elements 42 are arranged so as to face each other in the vicinity of the outer peripheral end on the mounting surface side of the light guide member 51. The LED light source module is electrically connected to the power supply unit 31 by wiring 37. Since the back surface of the mounting surface of the substrate 43 of the LED light source module is arranged in contact with the light source arrangement surface 82 of the light source setting portion 81, when the LED light source module generates heat, the heat of the LED light source module is transferred to the light source setting portion. It is transmitted to 81. When the ambient temperature on the mounting surface side of the light source setting unit 81 is lower than the temperature of the light source setting unit 81, the heat transferred to the light source setting unit 81 is transferred to the air around the mounting surface side of the light source setting unit 81. Further, a part of the heat transferred to the light source setting unit 81 is transmitted to the instrument body 21, and when the ambient temperature of the instrument body 21 is lower than the temperature of the instrument body 21, it is transmitted to the air around the instrument body 21. As a result, the heat transferred to the light source setting unit 81 is dissipated to the surroundings of the light source setting unit 81 and the instrument main body 21.

なお、本実施形態では、光源として表面実装型のLED素子42を用いたが、光源の種類はLED素子に限定されず、例えばCOB型発光モジュールや有機EL素子(OLED)などを用いても実現可能である。
また、基板43は、熱伝導性シート(図示せず)や放熱グリスを介して光源セット部81の光源配置面82に取り付けてもよく、これにより、より高い放熱性を得ることもできる。
In the present embodiment, the surface mount type LED element 42 is used as the light source, but the type of the light source is not limited to the LED element, and can be realized by using, for example, a COB type light emitting module or an organic EL element (OLED). It is possible.
Further, the substrate 43 may be attached to the light source arranging surface 82 of the light source setting portion 81 via a heat conductive sheet (not shown) or thermal paste, whereby higher heat dissipation can be obtained.

なお、本実施形態におけるセンサ露出部105に対応する平面視略台形状の光源部41の切欠き部45、導光部材51の切欠き部54、反射部材61の切欠き部63は、開口部の一例であり、切欠き部以外の貫通孔などの開口を形成する場合であってもよい。

The light guide member 51 is a substantially disk-shaped member. The light guide member 51 is made of a translucent resin material. The light guide member 51 is diffused. In the light guide member 51 of the present embodiment, a print layer is formed by white (semipermeable) silk printing in a dot pattern on the surface on the irradiation surface side exposed from the opening of the instrument main body 21. The light guide member 51 is not limited to the one in which the print layer of the dot pattern is formed, for example, the one in which the print layer other than the dot pattern is formed, and the one in which the surface is textured (frosted) with fine irregularities. , A diffuser is mixed inside, or a diffuse reflection sheet is attached. Further, a diffusion member may be separately provided on the irradiation surface side of the light guide member 51. The light guide member 51 has a tapered portion 52, a convex portion 53 projecting toward the irradiation surface side, and a concave portion 55 on the surface opposite to the convex portion 53. The tapered portion 52 is a tapered portion whose diameter is reduced downward from the outer peripheral edge portion of the light guide member 51. The convex portion 53 is a portion of the tapered portion 52 that projects outward in the radial direction from the tapered portion 52 at a position corresponding to the feeding element 44 of the light source portion 41. The convex portion 53 can be engaged with the notch portion 74 of the annular reflection member 71, and the light guide member 51 can be positioned when the light guide member 51 is attached to the annular reflection member 71. The light guide member 51 has an outer diameter dimension smaller than that of the annular reflection member 71, and can be locked to the tapered surface 73 of the annular reflection member 71. The recess 55 is formed so as to be convex toward the irradiation surface at a position corresponding to the power feeding element 44 of the light source unit 41. The recess 55 can be engaged with the power feeding element 44 when the light source unit 41 is arranged, and the light source unit 41 can be positioned at an appropriate position on the light guide member 51. The light guide member 51 also has a role of closing the opening below the instrument main body 21 to prevent dust and the like from adhering to the LED element 42.

The side reflecting portion 64 can be easily arranged at an appropriate position in the instrument main body 21 along the end surface of the cutout portion 54 of the light guide member 51.

なお、本実施形態では、反射部材61は、基板43と別体の部材として構成されているが、反射部材61の代わりに、例えば、基板43の照射面側の表面に、白色シールの貼り付けまたは白色塗装等を実行することで反射部を構成することもできる。 In the present embodiment, the reflective member 61 is configured as a member separate from the substrate 43, but instead of the reflective member 61, for example, a white sticker is attached to the surface of the substrate 43 on the irradiation surface side. Alternatively, the reflective portion can be configured by performing white coating or the like.

環状反射部材(第2反射部材)71は、導光部材51の外周縁の外側に配置され、当該外周縁を囲う反射部材である。環状反射部材71は、円環状で樹脂製の部材である。環状反射部材71は、外枠部72と、テーパ面73と、切欠き部74と、配線配置部75とを有している。外枠部72は、略円筒状の部分である。テーパ面73は、環状反射部材71の内周側に設けられ、内周側縁部から上方に向かうにつれて拡径する傾斜面である。テーパ面73は、LED素子42の下方に配置されている。テーパ面73は、導光部材51のテーパ部52から出る光を反射させる反射面である。テーパ面73には、導光部材51のテーパ部52が当接して配置される。切欠き部74は、テーパ面73の一部が矩形状に切り欠かれた部分であり、導光部材51の凸部53が係合する部分である。環状反射部材71の高さ寸法は、導光部材51の上面に反射部材61を配置した状態の高さ寸法よりも大きくなるように構成されている。環状反射部材71は、照明器具11を組み立てる際に、器具本体21の内部の下端隅部に最初に組み付けられる部材である。器具本体21に環状反射部材71が組み付けられた状態において、テーパ面73と器具本体21の反射部23aは、導光部材51の外周縁部の形状に対応した受け部を構成し、当該受け部に導光部材51が嵌合される。これにより、導光部材51を容易に適切な位置に位置決めして、配置することができる。 The annular reflective member (second reflective member) 71 is a reflective member that is arranged outside the outer peripheral edge of the light guide member 51 and surrounds the outer peripheral edge. The annular reflection member 71 is an annular member made of resin. The annular reflection member 71 has an outer frame portion 72, a tapered surface 73, a notch portion 74, and a wiring arrangement portion 75. The outer frame portion 72 is a substantially cylindrical portion. The tapered surface 73 is an inclined surface provided on the inner peripheral side of the annular reflection member 71 and whose diameter increases upward from the inner peripheral side edge portion. The tapered surface 73 is arranged below the LED element 42. The tapered surface 73 is a reflecting surface that reflects light emitted from the tapered portion 52 of the light guide member 51. The tapered portion 52 of the light guide member 51 is arranged in contact with the tapered surface 73. The notch portion 74 is a portion of the tapered surface 73 that is notched in a rectangular shape, and is a portion with which the convex portion 53 of the light guide member 51 engages. The height dimension of the annular reflective member 71 is configured to be larger than the height dimension when the reflective member 61 is arranged on the upper surface of the light guide member 51. The annular reflection member 71 is a member that is first assembled to the lower end corner inside the fixture body 21 when the lighting fixture 11 is assembled. In a state where the annular reflective member 71 is assembled to the instrument main body 21, the tapered surface 73 and the reflective portion 23a of the instrument main body 21 form a receiving portion corresponding to the shape of the outer peripheral edge portion of the light guide member 51, and the receiving portion. The light guide member 51 is fitted into the light guide member 51. As a result, the light guide member 51 can be easily positioned and arranged at an appropriate position.

外枠部72は、光源部41の給電素子44から延びる配線37に対応する位置において矩形状の切欠きである配線配置部75を有している。配線配置部75は配線37を配置するためのものである。この配線配置部75を設けることにより、配線37を光源セット部81の取付面側(背面側)に延ばすことが容易となり、電源部31に接続し易くなる。 The outer frame portion 72 has a wiring arrangement portion 75 which is a rectangular notch at a position corresponding to the wiring 37 extending from the power feeding element 44 of the light source portion 41. The wiring arrangement portion 75 is for arranging the wiring 37. By providing the wiring arrangement portion 75, it becomes easy to extend the wiring 37 toward the mounting surface side (back side) of the light source setting portion 81, and it becomes easy to connect to the power supply unit 31.

また、本実施形態では、器具本体21の内部に環状反射部材71、導光部材51、反射部材61を順に組み付けた際に、導光部材51の外周縁部の上部に断面視凹状で平面視円環状の素子収容部Sが形成される。素子収容部Sには、光源である複数のLED素子42が収容される。さらに、環状反射部材71は導光部材51の側面部の周囲を覆うとともに、反射部材61は素子収容部Sを除く導光部材51の上面を覆うように配置される。さらに、器具本体21の反射部23aは、導光部材51の照射面側において複数のLED素子42よりも径方向内側の領域を覆っている。このように構成することで、光源である複数のLED素子42と導光部材51との間にほとんど距離(空間)を設けることなく、LED素子42から出射される光を導光部材51の内部の導くことができる。これにより、光源であるLED素子42、導光部材51、反射部材61及び環状反射部材71の高さ寸法を抑えることができるため、ひいては照明器具11の高さ寸法の増大化を防ぐことができる。また、このような構成によれば、導光部材51の外周縁部である素子収容部Sのみから導光部材51の内部にLED素子42から出る光を入射することができるため、入射光を効率的に導光可能となる。こうして、本実施形態の照明器具11によれば、薄型でありながら均一性を高めた照明光を得ることができる。 Further, in the present embodiment, when the annular reflection member 71, the light guide member 51, and the reflection member 61 are assembled in this order inside the instrument main body 21, the light guide member 51 has a concave cross section and a plan view on the upper part of the outer peripheral edge portion. An annular element accommodating portion S is formed. A plurality of LED elements 42, which are light sources, are accommodated in the element accommodating portion S. Further, the annular reflection member 71 is arranged so as to cover the periphery of the side surface portion of the light guide member 51, and the reflection member 61 covers the upper surface of the light guide member 51 excluding the element accommodating portion S. Further, the reflective portion 23a of the instrument main body 21 covers a region radially inside the plurality of LED elements 42 on the irradiation surface side of the light guide member 51. With this configuration, the light emitted from the LED element 42 is emitted from the inside of the light guide member 51 with almost no distance (space) provided between the plurality of LED elements 42 which are light sources and the light guide member 51. Can be guided. As a result, the height dimensions of the LED element 42, the light guide member 51, the reflection member 61, and the annular reflection member 71, which are light sources, can be suppressed, and thus it is possible to prevent the height dimension of the luminaire 11 from increasing. .. Further, according to such a configuration, the light emitted from the LED element 42 can be incident inside the light guide member 51 only from the element accommodating portion S which is the outer peripheral edge portion of the light guide member 51, so that the incident light can be emitted. It becomes possible to guide light efficiently. In this way, according to the luminaire 11 of the present embodiment, it is possible to obtain illuminating light that is thin but has improved uniformity.

In the light source setting unit 81, the light source unit 41 is arranged on the light source arrangement surface 82, and the power supply unit 31, the terminal block 100, and the sensor unit 101 are arranged on the mounting surface side. The light source arranging surface 82 is formed to have a flat surface in order to increase the contact area with the substrate 43 in order to transfer the heat generated from the light source portion 41. The light source setting portion 81 has a cover locking portion 83, a cover mounting portion 84, and a terminal block mounting portion 85 on the mounting surface side.

光源セット部81の外周縁は、器具本体21の円筒部22の内周面の半径寸法と略同等の寸法である外側円弧部86と、外側円弧部86よりも小径で、光源セット部81を器具本体21の内部に収容する際に、対応する位置決め部22a等を挿通可能に形成される切欠きである内側円弧部87を有している。光源部41及び電源部31が取り付けられた光源セット部81を器具本体21に取り付ける際には、内側円弧部87により位置決め部22aを通過させるともに、当該光源セット部81を器具本体21の底部に配置後、周方向の一方側に所定長回動することで、外側円弧部86が位置決め部22aと下端凸部22cの間にその少なくとも一部が配置される。そうして、器具本体21のネジ固定部24に電源カバー33のネジ取付部33bと光源セット部81のカバー取付部84とを位置合わせした状態で、ネジ等の取付部材により共締めされる。このように、本実施形態では、器具本体21に対して光源部41と電源部31を有する光源セット部81を位置決めするともに、一つのネジ部材による固定だけで光源セット部81を器具本体21に安定して保持することができる。これにより、ネジ部材で固定する作業も少なく、光源セット部81の器具本体21への取付作業が容易となる。 The outer peripheral edge of the light source set portion 81 has an outer arc portion 86 having substantially the same radial dimension as the inner peripheral surface of the cylindrical portion 22 of the instrument body 21, and a light source set portion 81 having a diameter smaller than that of the outer arc portion 86. It has an inner arc portion 87 which is a notch formed so that a corresponding positioning portion 22a or the like can be inserted when the instrument main body 21 is housed inside. When the light source set unit 81 to which the light source unit 41 and the power supply unit 31 are attached is attached to the instrument body 21, the positioning unit 22a is passed by the inner arc portion 87, and the light source set unit 81 is placed on the bottom of the instrument body 21. After the arrangement, by rotating one side in the circumferential direction for a predetermined length, at least a part of the outer arc portion 86 is arranged between the positioning portion 22a and the lower end convex portion 22c. Then, in a state where the screw mounting portion 33b of the power supply cover 33 and the cover mounting portion 84 of the light source setting portion 81 are aligned with the screw fixing portion 24 of the instrument main body 21, they are jointly tightened by a mounting member such as a screw. As described above, in the present embodiment, the light source set unit 81 having the light source unit 41 and the power supply unit 31 is positioned with respect to the instrument body 21, and the light source set unit 81 is attached to the instrument body 21 only by fixing with one screw member. It can be held stably. As a result, the work of fixing with the screw member is small, and the work of attaching the light source setting portion 81 to the instrument main body 21 becomes easy.

光源セット部81は、外周縁部にセンサ部101のセンサ露出部105に対応する平面視略台形状の切欠き部88を有している。切欠き部88の径方向内側の辺縁部には、センサ取付部89が設けられている。センサ取付部89は、切欠き部88の径方向内側の辺縁部からL字状に立設した部分の上面部分であり、ネジ孔が開口されている。センサ取付部89は、センサ部101のネジ止め部108がネジ等の取付部材により取り付けられる部分である。また、切欠き部88の周方向両端の近傍には、センサ部101の爪部107が係止される一対の係止部90が設けられている。 The light source setting unit 81 has a substantially trapezoidal notch portion 88 in a plan view corresponding to the sensor exposed portion 105 of the sensor portion 101 on the outer peripheral edge portion. A sensor mounting portion 89 is provided on the radial inner edge portion of the notch portion 88. The sensor mounting portion 89 is an upper surface portion of a portion erected in an L shape from the radial inner edge portion of the notch portion 88, and has a screw hole. The sensor mounting portion 89 is a portion to which the screwed portion 108 of the sensor portion 101 is mounted by a mounting member such as a screw. Further, a pair of locking portions 90 for locking the claw portions 107 of the sensor portion 101 are provided in the vicinity of both ends of the notch portion 88 in the circumferential direction.

取付部材91は、照明器具11を被取付部Cに取り付ける際に、図示しないネジ等の取付部材により被取付部Cにあらかじめ取り付けられる、略円板状で樹脂製の部材である。取付部材91は、器具本体21を支持する支持部材でもあり、スタットとも呼ばれる。取付部材91は、取付板92、周壁部93、被係止部94、弾性係合部95等を有している。 The mounting member 91 is a substantially disk-shaped resin member that is pre-mounted to the mounted portion C by a mounting member such as a screw (not shown) when the lighting fixture 11 is mounted on the mounted portion C. The mounting member 91 is also a support member that supports the instrument main body 21, and is also called a stat. The mounting member 91 includes a mounting plate 92, a peripheral wall portion 93, a locked portion 94, an elastic engaging portion 95, and the like.

取付板92は、略円板状であり、取付部材91を被取付部Cに取り付けた際に、被取付部Cに対向する部分である。取付板92は、外部商用電源の電源電線(図示せず)を挿通するための貫通孔92aを有している。
周壁部93は、取付板92の外周縁から下方に延出される略円筒状の部分である。
The mounting plate 92 has a substantially disk shape, and is a portion facing the mounted portion C when the mounting member 91 is mounted on the mounted portion C. The mounting plate 92 has a through hole 92a for inserting a power line (not shown) of an external commercial power source.
The peripheral wall portion 93 is a substantially cylindrical portion extending downward from the outer peripheral edge of the mounting plate 92.

被係止部94は、周壁部93の周方向の複数箇所(本実施形態では、3箇所)に設けられている。被係止部94は、切欠き部94aと、切欠き部94aの周方向の一端部に隣接する案内部94bと、を有している。切欠き部94aは、周壁部93において側面視矩形状に切り欠いた部分であり、周方向の長さ寸法が器具本体21の係止部22bの周方向の長さ寸法よりも大きくなるように形成されている。これにより、器具本体21を取付部材91に取り付ける際、切欠き部94aに器具本体21の係止部22bを係合させることで器具本体21を位置決めすることができる。案内部94bは、周壁部93の外周面よりも径方向内側に配置される、短冊状の段差部分である。案内部94bは、器具本体21を取付部材91に取り付ける際に器具本体21を回動する方向に向かうにつれて被取付部C側(上方)に向かうように傾斜するテーパ面94cを有している。テーパ面94cは、湾曲状の面である。案内部94bは、器具本体21を取付部材91に取り付けるために周方向に回動した際に、器具本体21の係止部22bを所定の高さ位置(係止位置)まで案内するためのものである。このように案内部94bを構成することで、テーパ面94cの先端側(切欠き部94a側)が終端側よりも下方に下がっているため、器具本体21の係止部22bを案内部94bの終端側に係止する際に係止しやすく、かつ器具本体21を回動するだけで係止部22bを所定の高さ位置(係止位置)まで案内することができる(図9A参照)。また、係止部22bを案内部94bにより所定の高さ位置(係止位置)まで移動した際、案内部94bの下端部は、位置決め部22aの上端部に乗り上げるようにして位置決めされるため、取付部材91に対して器具本体21をガタツキ無く取り付けることができる(図9B参照)。
なお、本実施形態のテーパ面94cは、湾曲面で構成されているが、湾曲面の代わりに、例えば平坦面又は途中部が屈曲した屈曲面であってもよい。
The locked portions 94 are provided at a plurality of locations (three locations in the present embodiment) in the circumferential direction of the peripheral wall portion 93. The locked portion 94 has a notch portion 94a and a guide portion 94b adjacent to one end of the notch portion 94a in the circumferential direction. The notch portion 94a is a portion of the peripheral wall portion 93 that is cut out in a rectangular shape in a side view, so that the length dimension in the circumferential direction is larger than the length dimension in the circumferential direction of the locking portion 22b of the instrument main body 21. It is formed. As a result, when the instrument body 21 is attached to the attachment member 91, the instrument body 21 can be positioned by engaging the locking portion 22b of the instrument body 21 with the notch portion 94a. The guide portion 94b is a strip-shaped step portion arranged radially inside the outer peripheral surface of the peripheral wall portion 93. The guide portion 94b has a tapered surface 94c that inclines toward the attached portion C side (upward) as the instrument main body 21 is rotated in the direction in which the instrument main body 21 is attached to the attachment member 91. The tapered surface 94c is a curved surface. The guide portion 94b is for guiding the locking portion 22b of the appliance main body 21 to a predetermined height position (locking position) when the instrument main body 21 is rotated in the circumferential direction to be attached to the mounting member 91. Is. By configuring the guide portion 94b in this way, the tip side (notch portion 94a side) of the tapered surface 94c is lowered below the end side, so that the locking portion 22b of the instrument body 21 can be moved to the guide portion 94b. It is easy to lock when locking to the terminal side, and the locking portion 22b can be guided to a predetermined height position (locking position) simply by rotating the instrument main body 21 (see FIG. 9A). Further, when the locking portion 22b is moved to a predetermined height position (locking position) by the guide portion 94b, the lower end portion of the guide portion 94b is positioned so as to ride on the upper end portion of the positioning portion 22a. The instrument body 21 can be attached to the attachment member 91 without rattling (see FIG. 9B).
The tapered surface 94c of the present embodiment is composed of a curved surface, but instead of the curved surface, it may be, for example, a flat surface or a bent surface in which an intermediate portion is bent.

また、案内部94bは、周方向において切欠き部94aに隣接する先端部が角面取り加工されている。これにより、当該先端部が角部の場合と比べて、器具本体21を取り付ける際に、器具本体21の係止部22bがぶつかって、引っ掛かることを抑えることができる。 Further, in the guide portion 94b, the tip portion adjacent to the notch portion 94a in the circumferential direction is chamfered. As a result, it is possible to prevent the locking portion 22b of the instrument main body 21 from colliding with and being caught when the instrument main body 21 is attached, as compared with the case where the tip portion is a corner portion.

弾性係合部95は、平面視略U字形状のバネ部96と、バネ部96を保持するバネ保持部97とを有している。弾性係合部95は、バネ部96が径方向外側に向けて押圧力が働くようにバネ保持部97に保持されている。詳細は後述するが、弾性係合部95は、バネ部96の径方向外側の先端部が器具本体21の突条部22dに接触した際に掛かる径方向内側に向かう力に応じて出没可能に構成されている。 The elastic engaging portion 95 has a spring portion 96 having a substantially U-shape in a plan view, and a spring holding portion 97 that holds the spring portion 96. The elastic engaging portion 95 is held by the spring holding portion 97 so that the spring portion 96 exerts a pressing force outward in the radial direction. Although the details will be described later, the elastic engaging portion 95 can appear and disappear according to the radial inward force applied when the radial outer tip portion of the spring portion 96 comes into contact with the ridge portion 22d of the instrument body 21. It is configured.

上述したように取付部材91には、器具本体21の係止部22bを係止するために被係止部94が設けられている。器具本体21を取付部材91に取り付ける場合、作業者は器具本体21を手で把持した状態で、係止部22bを被係止部94の切欠き部94aに挿入し、この状態のまま器具本体21を周方向の一方に回動する。この回動の際には係止部22bが案内部94bにより係止位置(係止部22bの回動方向の終端位置)まで案内されるとともに案内部94bの下端部が位置決め部22aの上端に乗り上げる。同時に、この回動の際には、取付部材91に設けられた弾性係合部95が器具本体21の内周面を押圧しながら周方向に移動する。その際に突条部22dに差し掛かると、一方の傾斜面に沿って弾性係合部95のバネ部96の先端(バネ部96の突出部分)が径方向内側に移動する。さらに回動すると、当該バネ部96が突条部22dの頂部を乗り越えて他方の傾斜面に至ると、バネ部96の復元力によりバネ部96の先端は元の位置に戻り、器具本体21が取付部材91に対して回転しないようにする回転止めとなる(本実施形態では、突条部22dが二つ設けられるため、この過程が2回繰り返される)。このため、振動等により不意に器具本体21が取付部材91から外れることを防止することができる。また、器具本体21を取付部材91から取り外す場合は、取付部材91に対して器具本体21を上記回動方向とは反対方向に回動することで容易に取り外すことができる。また、突条部22dは、一方(取り外し時の回動方向側)の傾斜面よりも他方(取り付け時の回動方向側)の傾斜面を急峻となるように構成することで、器具本体21が取り外し方向に回動してもバネ部96が突条部22dを乗り越えにくい構造とすることもできる。
このように係止部22bを被係止部94に係止することで、器具本体21は取付部材91に取り付けられる。また、器具本体21が取付部材91に取り付けられた状態で器具本体21を周方向の他方に回動させると、器具本体21の係止部22bが取付部材91の被係止部94から外れて、器具本体21を取付部材91から取り外すことができる。
As described above, the mounting member 91 is provided with a locked portion 94 for locking the locking portion 22b of the instrument main body 21. When the instrument main body 21 is attached to the attachment member 91, the operator inserts the locking portion 22b into the notch portion 94a of the locked portion 94 while holding the instrument main body 21 by hand, and the instrument main body remains in this state. 21 is rotated in one direction in the circumferential direction. At the time of this rotation, the locking portion 22b is guided to the locking position (the end position in the rotation direction of the locking portion 22b) by the guide portion 94b, and the lower end portion of the guide portion 94b is at the upper end of the positioning portion 22a. Get on. At the same time, at the time of this rotation, the elastic engaging portion 95 provided on the mounting member 91 moves in the circumferential direction while pressing the inner peripheral surface of the instrument main body 21. At that time, when the protrusion portion 22d is approached, the tip of the spring portion 96 of the elastic engaging portion 95 (the protruding portion of the spring portion 96) moves inward in the radial direction along one of the inclined surfaces. When the spring portion 96 is further rotated and reaches the other inclined surface over the top of the ridge portion 22d, the tip of the spring portion 96 returns to the original position due to the restoring force of the spring portion 96, and the instrument body 21 is moved. It is a rotation stopper that prevents the mounting member 91 from rotating (in this embodiment, since two protrusions 22d are provided, this process is repeated twice). Therefore, it is possible to prevent the instrument body 21 from being unexpectedly detached from the mounting member 91 due to vibration or the like. Further, when the instrument body 21 is removed from the mounting member 91, the instrument body 21 can be easily removed by rotating the instrument body 21 with respect to the mounting member 91 in a direction opposite to the rotation direction. Further, the ridge portion 22d is configured so that the inclined surface of one (rotation direction side at the time of removal) is steeper than the inclined surface of the other (rotation direction side at the time of attachment), so that the instrument main body 21 The structure may be such that the spring portion 96 does not easily get over the ridge portion 22d even if the spring portion 96 rotates in the removal direction.
By locking the locking portion 22b to the locked portion 94 in this way, the instrument main body 21 is attached to the mounting member 91. Further, when the instrument body 21 is rotated to the other side in the circumferential direction while the instrument body 21 is attached to the mounting member 91, the locking portion 22b of the instrument body 21 is disengaged from the locked portion 94 of the mounting member 91. , The instrument body 21 can be removed from the mounting member 91.

図10に示すように、取付部材91には、パッキン98が取り付け可能である。
パッキン98は、平面視円形状で凹状の弾性部材であり、取付部材91の取付板92の取付面側を覆うものである。パッキン98の外周縁には、下方に延出される円環部98aを有している。円環部98aは、器具本体21の円筒部22の上端部の外周側を覆う部分である。パッキン98には、取付部材91が有する貫通孔92a等の開口部及び位置合わせ用凸部などに対応する開口部が設けられている。パッキン98は、照明器具11を被取付部Cに取り付けた際に、器具本体21により被取付部C側に押されて、圧縮変形する。これにより、取付部材91と被取付部Cとの隙間を密閉することができる。また、照明器具11は、圧縮変形したパッキン98が元の形状に戻ろうとする力により被取付部Cから離れる方向へ押されるため、被取付部Cに取り付けられた状態においてぐらつきが少なく姿勢が安定する。
As shown in FIG. 10, the packing 98 can be attached to the attachment member 91.
The packing 98 is a circular elastic member in a plan view and is concave, and covers the mounting surface side of the mounting plate 92 of the mounting member 91. The outer peripheral edge of the packing 98 has an annular portion 98a extending downward. The annular portion 98a is a portion that covers the outer peripheral side of the upper end portion of the cylindrical portion 22 of the instrument main body 21. The packing 98 is provided with an opening such as a through hole 92a included in the mounting member 91 and an opening corresponding to a convex portion for alignment and the like. When the lighting fixture 11 is attached to the attached portion C, the packing 98 is pushed toward the attached portion C by the appliance main body 21 and is compressed and deformed. As a result, the gap between the mounting member 91 and the mounted portion C can be sealed. Further, since the luminaire 11 is pushed away from the attached portion C by the force of the compression-deformed packing 98 returning to its original shape, there is little wobbling and the posture is stable when the luminaire 11 is attached to the attached portion C. To do.

パッキン98は、照射面側の中央の開口部近傍において側面視略三角形状の一対の凸部と、外周部近傍にリブ部99を有している。凸部は、取付板92の対応する位置に開口した貫通孔に挿通することで、取付板92にパッキン98を密着させて固定するものである。 The packing 98 has a pair of convex portions having a substantially triangular shape in a side view in the vicinity of the central opening on the irradiation surface side, and a rib portion 99 in the vicinity of the outer peripheral portion. The convex portion is inserted into a through hole opened at a corresponding position of the mounting plate 92 to bring the packing 98 into close contact with the mounting plate 92 and fix it.

図11に示すように、リブ部99は、径方向に沿って凹凸が連続する平面視円環状の複数のリブRである。リブRは、径方向外側に向かうにつれて拡径する第1傾斜面R1と、第1傾斜面R1より急峻な傾斜面である第2傾斜面R2とを有している。複数のリブRは、径方向外側に向かって傾斜するように角部が形成されている。すなわち、リブRは、外周側が急峻な傾斜面であり、内周側が外周側よりも緩やかな傾斜面になるように形成されている。複数のリブRは、器具本体21が取付部材91に取り付けられた際に、器具本体21の円筒部22の上端部に当接する。これにより、複数のリブRを設けない平坦面に比べて、円筒部22の上端部との接触面積が増大し、照明器具11の内部に水等が浸入しにくい構造となる。よって、照明器具11は、雨等の影響を受けやすいエクステリア用照明器具として好適なものとなる。
なお、パッキン98は、用途に応じて省略することができる。図1から図5においては、パッキン98を省略した照明器具11を示している。
As shown in FIG. 11, the rib portion 99 is a plurality of ribs R having an annular shape in a plan view in which irregularities are continuous along the radial direction. The rib R has a first inclined surface R1 whose diameter increases toward the outside in the radial direction, and a second inclined surface R2 which is an inclined surface steeper than the first inclined surface R1. The corners of the plurality of ribs R are formed so as to incline outward in the radial direction. That is, the rib R is formed so that the outer peripheral side is a steep inclined surface and the inner peripheral side is a gentler inclined surface than the outer peripheral side. The plurality of ribs R abut on the upper end of the cylindrical portion 22 of the instrument body 21 when the instrument body 21 is attached to the attachment member 91. As a result, the contact area with the upper end portion of the cylindrical portion 22 is increased as compared with the flat surface on which the plurality of ribs R are not provided, and the structure is such that water or the like is less likely to enter the inside of the luminaire 11. Therefore, the lighting fixture 11 is suitable as an exterior lighting fixture that is easily affected by rain or the like.
The packing 98 may be omitted depending on the intended use. 1 to 5 show the luminaire 11 in which the packing 98 is omitted.

The operation switch 105c is an operation setting switch that switches, for example, the lighting time. The operation knob 105d is, for example, an illuminance adjustment knob for adjusting the illuminance.

センサ受光部105bは、センサ操作面105aの周方向の一端側に偏在している。操作スイッチ105c及び操作つまみ105dは、センサ操作面105aの周方向の他端側に偏在している。 The sensor light receiving unit 105b is unevenly distributed on one end side of the sensor operation surface 105a in the circumferential direction. The operation switch 105c and the operation knob 105d are unevenly distributed on the other end side of the sensor operation surface 105a in the circumferential direction.

段差部106は、センサ露出部105の外周縁側を除く周囲部分に設けられる段差形状の部分である。段差部106は、複数の段差を有し、上段から第1段差部106aと、第1段差部106aよりも下方に設けられる段差である第2段差部106bとを有している。第1段差部106aは、導光部材51の切欠き部54及び反射部材61の切欠き部63が位置決めされて配置される部分である。第2段差部106bは、光源セット部81が位置決めされて配置される部分である。 The step portion 106 is a step-shaped portion provided in a peripheral portion excluding the outer peripheral edge side of the sensor exposed portion 105.

これにより、センサ部101に最も近接するLED素子42aにおいて、当該LED素子42aから導光部材51の外周側から内側に導光する構成であるため、センサ部101が光を遮ることによる影の発生を抑止して照明光のムラを低減することができる。ひいては、導光部材51の面発光をより均一性を高めることができる。
In the lighting fixture 11 of the present embodiment, a plurality of LED elements 42 are arranged so as to face each other in the vicinity of the outer peripheral end of the light guide member 51. Further, as shown in FIG. 2, the light guide member 51 has a notch portion 54 at a position corresponding to the sensor exposed portion 105 of the sensor portion 101, and the sensor exposed portion 105 is passed through the notch portion 54. It is exposed. Further, the LED element 42a closest to the sensor unit 101 among the plurality of LED elements 42 has a configuration in which the line connecting the LED element 42a and the center E of the light guide member 51 does not overlap with the notch portion 54. ..
As a result, the LED element 42a closest to the sensor unit 101 is configured to guide light from the LED element 42a from the outer peripheral side to the inside of the light guide member 51, so that the sensor unit 101 blocks light to generate shadows. Can be suppressed and unevenness of the illumination light can be reduced. As a result, the surface emission of the light guide member 51 can be made more uniform.

また、図2に示すように、本実施形態の照明器具11では、導光部材51の切欠き部54は、平面視略台形状であり、向かい合う斜辺をそれぞれ延長した点線L・Lの交点Pが導光部材51の照射面(切欠き部54を除く部分)と平面視で重なる位置になるように形成されている。
このような形状となるように切欠き部54を形成することにより、導光部材51の外周縁近傍に位置する、センサ部101に最も近接するLED素子42aからの光を遮りにくい。
Further, as shown in FIG. 2, in the lighting fixture 11 of the present embodiment, the notch portion 54 of the light guide member 51 has a substantially trapezoidal shape in a plan view, and the intersection P of the dotted lines L and L, which extend the opposing hypotenuses, respectively. Is formed so as to overlap the irradiation surface of the light guide member 51 (the portion excluding the notch 54) in a plan view.
By forming the notch portion 54 so as to have such a shape, it is difficult to block the light from the LED element 42a located near the outer peripheral edge of the light guide member 51 and closest to the sensor portion 101.

また、本実施形態の照明器具11では、センサ部101は、段差部106を有し、光源セット部81の一端である切欠き部88が段差部106の第1段差部106aに組み付けられる。
これにより、光源セット部81(光源部41)とセンサ部101との位置を適正な位置に位置決めすることができる。
Further, in the luminaire 11 of the present embodiment, the sensor unit 101 has a step portion 106, and the notch portion 88, which is one end of the light source setting portion 81, is assembled to the first step portion 106a of the step portion 106.
As a result, the positions of the light source setting unit 81 (light source unit 41) and the sensor unit 101 can be positioned at appropriate positions.

また、本実施形態の照明器具11では、照明器具11の照射面側に露出する、センサ受光部105b及び、センサ操作部である操作スイッチ105c及び操作つまみ105dを有するともに、光源セット部81に取り付けられるセンサ部101と、を備え、センサ受光部105bは、センサ操作部である操作スイッチ105c及び操作つまみ105dと隣り合うとともに、センサ部101のセンサ露出面105の一方側に偏在している。
このような構成によれば、センサ操作部である操作スイッチ105c及び操作つまみ105d照明器具11の照射面側に露出することで、照明器具11を被取付部Cに取り付けた後であってもセンサ操作部の視認性がよく、調整しやすい。さらに、例えば、従来からある、センサ露出部105においてセンサ受光部105bを中央に配置し、操作スイッチ105c及び操作つまみ105dを、当該センサ受光部105bを挟むように対向して配置した場合に比べて、操作スイッチ105c及び操作つまみ105dを操作するためのスペースを確保することができるとともに、センサ操作面105aを小さく構成することができる。センサ操作面105aを小さくするため、導光部材51の照射面を広く確保することができる。
Further, the luminaire 11 of the present embodiment has a sensor light receiving unit 105b exposed on the irradiation surface side of the illuminator 11, an operation switch 105c which is a sensor operation unit, and an operation knob 105d, and is attached to the light source set unit 81. The sensor unit 101 is provided, and the sensor light receiving unit 105b is adjacent to the operation switch 105c and the operation knob 105d, which are sensor operation units, and is unevenly distributed on one side of the sensor exposed surface 105 of the sensor unit 101.
According to such a configuration, by exposing the operation switch 105c and the operation knob 105d, which are the sensor operation units, to the irradiation surface side of the luminaire 11, the sensor is exposed even after the luminaire 11 is attached to the attached portion C. The visibility of the operation unit is good and it is easy to adjust. Further, for example, as compared with the conventional case where the sensor light receiving part 105b is arranged in the center of the sensor exposed part 105, and the operation switch 105c and the operation knob 105d are arranged so as to sandwich the sensor light receiving part 105b. , The space for operating the operation switch 105c and the operation knob 105d can be secured, and the sensor operation surface 105a can be made small. Since the sensor operation surface 105a is made small, the irradiation surface of the light guide member 51 can be secured widely.

また、本実施形態の照明器具11では、LED素子42は、導光部材51の外周端近傍に対向して複数配置され、センサ部101は、少なくとも導光部材51の外周端近傍を切り欠いた領域において照明器具11の照射面側に露出している。これにより、センサ部101の外周縁部分に占める領域が狭くなるため、LED素子42を配置するスペースを確保することが可能となり、基板43上に実装するLED素子42の数を増加させることができる。これにより、照明器具11の照度を向上させることが可能となる。 Further, in the lighting fixture 11 of the present embodiment, a plurality of LED elements 42 are arranged so as to face each other in the vicinity of the outer peripheral end of the light guide member 51, and the sensor unit 101 cuts out at least the vicinity of the outer peripheral end of the light guide member 51. The area is exposed on the irradiation surface side of the luminaire 11. As a result, the area occupied by the outer peripheral edge portion of the sensor unit 101 is narrowed, so that it is possible to secure a space for arranging the LED element 42, and it is possible to increase the number of LED elements 42 mounted on the substrate 43. .. This makes it possible to improve the illuminance of the luminaire 11.

また、本実施形態の照明器具11では、センサ部101のセンサ受光部105bは、センサ露出部105において器具本体21の取付時に回動させる方向側(図2において矢印F方向側)に偏在している。これにより、照明器具11を被取付部Cに取り付けた状態で、センサ操作部(操作スイッチ105c及び操作つまみ105d)を操作するとき、センサ操作部がセンサ受光部105bの影になりにくく、操作する者が視認し易い。 Further, in the lighting fixture 11 of the present embodiment, the sensor light receiving portion 105b of the sensor portion 101 is unevenly distributed in the sensor exposed portion 105 on the direction side (the arrow F direction side in FIG. 2) to be rotated when the fixture main body 21 is attached. There is. As a result, when the sensor operation unit (operation switch 105c and operation knob 105d) is operated with the luminaire 11 attached to the attachment unit C, the sensor operation unit is less likely to be in the shadow of the sensor light receiving unit 105b and is operated. Easy for people to see.
