続いて、本実施の形態に係る照明器具1の構成要素間の係止構成について説明する。
[2. Locking configuration]
Then, the latching structure between the components of the lighting fixture 1 which concerns on this Embodiment is demonstrated.

[2−1.取付部材と反射部材との間の係止構成]
まず、取付部材13と反射部材16との係止構成について図4及び図5を用いて説明する。
[2-1. Locking structure between mounting member and reflecting member]
First, a locking configuration between the attachment member 13 and the reflection member 16 will be described with reference to FIGS. 4 and 5.

図5は、本実施の形態に係る取付部材13と反射部材16との間の係止構成を示す斜視図である。   FIG. 5 is a perspective view showing a locking configuration between the attachment member 13 and the reflection member 16 according to the present embodiment.

図4及び図5に示されるように、取付部材13には、反射部材16を係止する第二係止部131が設けられる。反射部材16には、第二係止部131に係止される第二被係止部164が設けられる。反射部材16は、第二被係止部164が第二係止部131に係止されることによって取付部材13に支持される。これにより、本実施の形態では、締結部材を用いずに、反射部材16を取付部材13に容易に支持させることができる。   As shown in FIGS. 4 and 5, the attachment member 13 is provided with a second locking portion 131 that locks the reflecting member 16. The reflecting member 16 is provided with a second locked portion 164 that is locked to the second locking portion 131. The reflecting member 16 is supported by the mounting member 13 by the second locked portion 164 being locked to the second locking portion 131. Thereby, in this Embodiment, the reflection member 16 can be easily supported by the attachment member 13 without using a fastening member.

第二係止部131は、第二被係止部164にスナップ方式によって係止される。すなわち、第二係止部131を弾性変形させた状態で、第二被係止部164まで移動させ、弾性変形を解消させることによって、第二係止部131の端部が第二被係止部164に挿入される。以下、反射部材16を取付部材13に支持させる手順を具体的に説明する。図5に示されるように、器具本体11にねじ15によって締結された取付部材13に対して、反射部材16を光源12の光軸J方向に移動させる。ここで、図4に示されるように、取付部材13に設けられた二つの第二係止部131の反射部材16側の端部には、光軸J方向に対して傾斜した傾斜面(突起)が形成されている。二つの第二係止部131の端部の傾斜面は、光源12に近づくほど、光軸Jから遠ざかる。これにより、二つの第二係止部131の端部は、反射部材16の二つの立設部163の間隙に、二つの立設部163と干渉することなく挿入される。一方、二つの第二係止部131が二つの立設部163の間隙にさらに挿入される(取付部材13に反射部材16がさらに近づけられる)場合には、二つの第二係止部131の光軸Jから遠ざかる向きに突出した部分が、二つの立設部163の光軸J側の面と干渉する。すなわち、各第二係止部131が立設部163によって、光軸J向きに押される。このため、二つの第二係止部131が光軸J向きに弾性変形する。二つの第二係止部131が、二つの立設部163の間隙にさらに挿入されることにより、二つの第二係止部131の各端部が第二被係止部164に挿入される。これにより、各第二係止部131の弾性変形が解消される。以上のように、第二係止部131の端部が第二被係止部164に挿入されることにより、第二被係止部164は、第二係止部131に係止される。つまり、第二被係止部164が、第二係止部131に対して、鉛直方向下向き(Y軸方向負向き)に移動することが抑制される。   The second locking portion 131 is locked to the second locked portion 164 by a snap method. That is, in a state where the second locking portion 131 is elastically deformed, the second locking portion 131 is moved to the second locked portion 164 to cancel the elastic deformation, whereby the end of the second locking portion 131 is moved to the second locked portion. It is inserted into the part 164. Hereinafter, a procedure for supporting the reflecting member 16 on the mounting member 13 will be specifically described. As shown in FIG. 5, the reflecting member 16 is moved in the direction of the optical axis J of the light source 12 with respect to the attachment member 13 fastened to the instrument main body 11 with the screw 15. Here, as shown in FIG. 4, the two second locking portions 131 provided on the attachment member 13 have inclined surfaces (protrusions) inclined with respect to the optical axis J direction at the ends on the reflecting member 16 side. ) Is formed. The inclined surfaces at the ends of the two second locking portions 131 are further away from the optical axis J as they approach the light source 12. Accordingly, the end portions of the two second locking portions 131 are inserted into the gap between the two standing portions 163 of the reflecting member 16 without interfering with the two standing portions 163. On the other hand, when the two second locking portions 131 are further inserted into the gap between the two standing portions 163 (the reflecting member 16 is further brought closer to the mounting member 13), the two second locking portions 131 The portion protruding in the direction away from the optical axis J interferes with the surface of the two standing portions 163 on the optical axis J side. That is, each second locking portion 131 is pushed toward the optical axis J by the standing portion 163. Therefore, the two second locking portions 131 are elastically deformed in the direction of the optical axis J. The two second locking portions 131 are further inserted into the gap between the two standing portions 163, so that the end portions of the two second locking portions 131 are inserted into the second locked portion 164. . Thereby, the elastic deformation of each 2nd latching | locking part 131 is eliminated. As described above, the second locked portion 164 is locked to the second locking portion 131 by inserting the end portion of the second locking portion 131 into the second locked portion 164. That is, the second locked portion 164 is restrained from moving downward in the vertical direction (negative in the Y-axis direction) with respect to the second locking portion 131.

上述のとおり、第二係止部131によって第二被係止部164を係止する際に、第二係止部131を弾性変形させる必要があるため、第二係止部131にストレスがかかる。このようなストレスに加えて、照明器具1の搬送中の振動によるストレス、経年劣化などに起因して、樹脂で形成された第二係止部131が破損する場合があり得る。   As described above, when the second locked portion 164 is locked by the second locking portion 131, it is necessary to elastically deform the second locking portion 131, so that stress is applied to the second locking portion 131. . In addition to such stress, the second locking portion 131 made of resin may be damaged due to stress due to vibration during transportation of the lighting fixture 1, deterioration over time, or the like.

[2−2.反射部材と光学部材との間の係止構成]
続いて、反射部材16と光学部材30との係止構成について図6〜8を用いて説明する。
[2-2. Locking configuration between reflecting member and optical member
Next, a locking configuration between the reflecting member 16 and the optical member 30 will be described with reference to FIGS.

図6は、本実施の形態に係る反射部材16に光学部材30が係止された状態を示す斜視図である。   FIG. 6 is a perspective view showing a state in which the optical member 30 is locked to the reflecting member 16 according to the present embodiment.

図7は、本実施の形態に係る反射部材16に光学部材30が係止された状態を光軸J方向から見た平面図である。図7には、反射部材16及び光学部材30を、Y軸方向負側から見た平面図が示されている。また、図7には、枠体40の入射開口部411を光軸J方向に投影した場合に、光学部材30のフランジ部310に投影される像411aが破線で示される。   FIG. 7 is a plan view of the state in which the optical member 30 is locked to the reflecting member 16 according to the present embodiment as viewed from the optical axis J direction. FIG. 7 shows a plan view of the reflecting member 16 and the optical member 30 as viewed from the Y axis direction negative side. In FIG. 7, an image 411 a projected on the flange portion 310 of the optical member 30 when the incident opening 411 of the frame body 40 is projected in the optical axis J direction is indicated by a broken line.

図8は、本実施の形態に係る反射部材16及び光学部材30の断面図である。図8においては、図7に示されるVIII−VIII線における断面が示されている。   FIG. 8 is a cross-sectional view of the reflecting member 16 and the optical member 30 according to the present embodiment. In FIG. 8, the cross section in the VIII-VIII line shown by FIG. 7 is shown.

図6〜8に示されるように、反射部材16のフランジ部162は、光学部材30の光軸Jに垂直な方向(Y軸に垂直な方向)への移動を規制する規制部165を有する。規制部165は、フランジ部162の周縁部付近の光学部材30側(Y軸方向負側)に立設されている。規制部165は、光学部材30を光源12の光軸J方向に見た場合における外縁315に沿って設けられる。これに伴い、反射部材16を光軸J方向に見た場合における外縁168も光学部材30の外縁315と同様の形状を有する。   As shown in FIGS. 6 to 8, the flange portion 162 of the reflecting member 16 has a restricting portion 165 that restricts the movement of the optical member 30 in the direction perpendicular to the optical axis J (direction perpendicular to the Y axis). The restricting portion 165 is erected on the optical member 30 side (Y-axis direction negative side) in the vicinity of the peripheral edge portion of the flange portion 162. The restricting portion 165 is provided along the outer edge 315 when the optical member 30 is viewed in the optical axis J direction of the light source 12. Accordingly, the outer edge 168 when the reflecting member 16 is viewed in the optical axis J direction has the same shape as the outer edge 315 of the optical member 30.

規制部165は、光学部材30を係止するための第一係止部166を有する。なお、本実施の形態では、規制部165は、三つの第一係止部166を有する。光学部材30には、フランジ部310のY軸方向負側の面に、三つの第一被係止部311が設けられる。本実施の形態では、三つの第一被係止部311は、光学部材30のフランジ部310のY軸方向負側に設けられた凹部である。図6〜8に示されるように、三つの第一被係止部311は、三つの第一係止部166と対応する位置に設けられる。光学部材30は、各第一被係止部311が対応する第一係止部166に係止されることによって灯体10に支持される。これにより、本実施の形態では、締結部材を用いずに、光学部材30を灯体10に容易に支持させることができる。   The restricting portion 165 has a first locking portion 166 for locking the optical member 30. In the present embodiment, the restricting portion 165 has three first locking portions 166. The optical member 30 is provided with three first locked portions 311 on the surface of the flange portion 310 on the Y axis direction negative side. In the present embodiment, the three first locked portions 311 are concave portions provided on the Y axis direction negative side of the flange portion 310 of the optical member 30. As shown in FIGS. 6 to 8, the three first locked portions 311 are provided at positions corresponding to the three first locked portions 166. The optical member 30 is supported by the lamp body 10 as each first locked portion 311 is locked to the corresponding first locking portion 166. Thereby, in this Embodiment, the optical member 30 can be easily supported by the lamp body 10 without using a fastening member.

第一係止部166は、第一被係止部311にスナップ方式によって係止される。すなわち、第一係止部166を弾性変形させた状態で、第一被係止部311まで移動させ、弾性変形を解消させることによって、第一係止部166の端部が第一被係止部311に配置される。以下、光学部材30を反射部材16に支持させる手順を具体的に説明する。   The first locking portion 166 is locked to the first locked portion 311 by a snap method. That is, in a state where the first locking portion 166 is elastically deformed, the first locking portion 166 is moved to the first locked portion 311 to cancel the elastic deformation, whereby the end portion of the first locking portion 166 is moved to the first locked portion. The unit 311 is arranged. Hereinafter, a procedure for supporting the optical member 30 on the reflecting member 16 will be specifically described.

光学部材30を反射部材16に支持させる際には、反射部材16に対して、光学部材30を光源12の光軸J方向に移動させる。ここで、図6及び図8に示されるように、反射部材16に設けられた三つの第一係止部166のY軸方向負側の端部には、光軸J方向に対して傾斜した傾斜面(突起)が形成されている。三つの第一係止部166のY軸方向負側端部の傾斜面は、光源12に近づくほど、光軸Jに近づく。これにより、光学部材30のフランジ部310のY軸方向正側端部は、三つの第一係止部166で囲まれる部分に、各第一係止部166と干渉することなく挿入される。一方、光学部材30のフランジ部310と反射部材16のフランジ部162とを近づける方向に、光学部材30をさらに移動させる場合には、三つの第一係止部166の傾斜面が、光学部材30の外周面と干渉する。すなわち、各第一係止部166が光学部材30によって、光軸Jから遠ざかる向きに押される。このため、三つの第一係止部166が光軸Jから遠ざかる向きに弾性変形する。光学部材30が、フランジ部310のY軸方向における厚さ程度の距離だけさらに移動されることにより、各第一係止部166の傾斜面が光学部材30の各第一被係止部311を係止する位置に到達する。これにより、各第一係止部166の弾性変形が解消される。   When the optical member 30 is supported by the reflecting member 16, the optical member 30 is moved in the optical axis J direction of the light source 12 with respect to the reflecting member 16. Here, as shown in FIGS. 6 and 8, the Y-axis direction negative side end portions of the three first locking portions 166 provided on the reflecting member 16 are inclined with respect to the optical axis J direction. An inclined surface (projection) is formed. The inclined surfaces at the Y axis direction negative side end portions of the three first locking portions 166 are closer to the optical axis J as they are closer to the light source 12. Thereby, the Y axis direction positive side end of the flange portion 310 of the optical member 30 is inserted into the portion surrounded by the three first locking portions 166 without interfering with the first locking portions 166. On the other hand, when the optical member 30 is further moved in the direction in which the flange portion 310 of the optical member 30 and the flange portion 162 of the reflecting member 16 are brought closer to each other, the inclined surfaces of the three first locking portions 166 are the optical member 30. Interfering with the outer peripheral surface. That is, each first locking portion 166 is pushed by the optical member 30 in a direction away from the optical axis J. For this reason, the three first locking portions 166 are elastically deformed in a direction away from the optical axis J. When the optical member 30 is further moved by a distance of about the thickness of the flange portion 310 in the Y-axis direction, the inclined surface of each first locking portion 166 causes each first locked portion 311 of the optical member 30 to move. The position to be locked is reached. Thereby, the elastic deformation of each 1st latching | locking part 166 is eliminated.

以上のように、第一係止部166の端部が第一被係止部311を係止することにより、光学部材30が、第一係止部166に対して、鉛直方向下向き(Y軸方向負向き)に移動することが抑制される。   As described above, the end of the first locking portion 166 locks the first locked portion 311, so that the optical member 30 is directed downward in the vertical direction with respect to the first locking portion 166 (Y axis). (Moving in the negative direction) is suppressed.

上述のとおり、第一係止部166によって第一被係止部311を係止する際に、第一係止部166を弾性変形させる必要があるため、上記第二係止部131と同様に、樹脂で形成された第一係止部166が破損する場合があり得る。   As described above, when the first locked portion 311 is locked by the first locking portion 166, it is necessary to elastically deform the first locking portion 166. The first locking part 166 made of resin may be damaged.

特に、光学部材30がフレネルレンズである場合には、光学部材30の厚さが比較的厚くなる。そのため、光学部材30の重量も重くなるため、第一係止部166などに加わる力が大きくなる。したがって、第一係止部166などの破損が生じやすくなる。   In particular, when the optical member 30 is a Fresnel lens, the thickness of the optical member 30 is relatively thick. Therefore, since the weight of the optical member 30 also becomes heavy, the force added to the 1st latching | locking part 166 etc. becomes large. Therefore, the first locking portion 166 and the like are easily damaged.

[3.光学部材離脱抑制構成]
上述したとおり、樹脂で形成された第一係止部166及び第二係止部131が破損する場合があり得る。本実施の形態に係る照明器具1は、第一係止部166及び第二係止部131の少なくとも一方が破損した場合においても、光学部材30及び反射部材16が照明器具1から離脱することを抑制できる構成を有する。当該構成について、図4及び図7を用いて説明する。
[3. Optical member detachment suppression configuration]
As described above, the first locking portion 166 and the second locking portion 131 formed of resin may be damaged. In the lighting fixture 1 according to the present embodiment, even when at least one of the first locking portion 166 and the second locking portion 131 is damaged, the optical member 30 and the reflecting member 16 are detached from the lighting fixture 1. It has a configuration that can be suppressed. This configuration will be described with reference to FIGS.

図4及び図7に示される枠体40の入射開口部411の像411aは、照明器具1を光軸方向に見た場合における入射開口部411の配置に対応する。したがって、図4及び図7から分かるように、光学部材30を光源12の光軸J方向に見た場合に、光学部材30の外縁315の少なくとも一部は、入射開口部411の外側に位置する。また、反射部材16を光軸J方向に見た場合に、反射部材16の外縁168の少なくとも一部は、入射開口部411の外側に位置する。これにより、第一係止部166及び第二係止部131が破損した場合においても、光学部材30及び反射部材16が、枠体40の入射開口部411から抜け出ることが抑制される。したがって、光学部材30及び反射部材16の照明器具1からの離脱が抑制される。本実施の形態では、光学部材30及び反射部材16を光軸J方向に見た場合に、光学部材30の外縁315及び反射部材16の外縁168は、全周に亘って入射開口部411の外側に位置する。つまり、光学部材30及び反射部材16の外径は、入射開口部411の内径より大きい。これにより、光学部材30及び反射部材16の照明器具1からの離脱をより確実に抑制できる。   The image 411a of the incident opening 411 of the frame 40 shown in FIGS. 4 and 7 corresponds to the arrangement of the incident opening 411 when the luminaire 1 is viewed in the optical axis direction. Therefore, as can be seen from FIGS. 4 and 7, when the optical member 30 is viewed in the optical axis J direction of the light source 12, at least a part of the outer edge 315 of the optical member 30 is located outside the incident opening 411. . Further, when the reflecting member 16 is viewed in the optical axis J direction, at least a part of the outer edge 168 of the reflecting member 16 is located outside the incident opening 411. Thereby, even when the 1st latching | locking part 166 and the 2nd latching | locking part 131 are damaged, it is suppressed that the optical member 30 and the reflection member 16 slip out from the incident opening part 411 of the frame 40. FIG. Therefore, the separation of the optical member 30 and the reflecting member 16 from the lighting fixture 1 is suppressed. In the present embodiment, when the optical member 30 and the reflecting member 16 are viewed in the optical axis J direction, the outer edge 315 of the optical member 30 and the outer edge 168 of the reflecting member 16 are outside the incident opening 411 over the entire circumference. Located in. That is, the outer diameters of the optical member 30 and the reflecting member 16 are larger than the inner diameter of the incident opening 411. Thereby, the detachment | leave from the lighting fixture 1 of the optical member 30 and the reflection member 16 can be suppressed more reliably.

また、反射部材16の外縁168が入射開口部411より外側に位置することにより、Y軸方向負側から照明器具1を見た場合に、入射開口部411の内側には、反射部材16、光学部材30及び光源12だけが見える。つまり、照明器具1の内部の配線などが、照明器具1の外部から見られることを抑制することができる。これにより、ユーザらが、照明器具1の内部の配線などに触れることを抑制できる。また、照明器具1の内部が見えない構成は、外観デザイン上も好ましい。   In addition, since the outer edge 168 of the reflecting member 16 is positioned outside the incident opening 411, when the luminaire 1 is viewed from the Y axis direction negative side, the reflecting member 16 and the optical are located inside the incident opening 411. Only member 30 and light source 12 are visible. That is, it can suppress that the wiring inside the lighting fixture 1 etc. are seen from the exterior of the lighting fixture 1. FIG. Thereby, it can suppress that users touch the wiring etc. inside the lighting fixture 1. FIG. Moreover, the structure which cannot see the inside of the lighting fixture 1 is preferable also on an external appearance design.

なお、本実施の形態では、図4に示されるように、入射開口部411において補助反射部材410が枠本体420の端部421においてかしめられていることに起因して、補助反射部材410の光学部材30寄りの端部414の光軸J方向における平坦度が比較的低い。そのため、端部414を光学部材30などに当接させる場合に、端部414の全周を光学部材30に当接させることが難しい。そのため、本実施の形態では、枠体40(端部414)を光学部材30に当接させない構成が採用されている。なお、入射開口部411を光学部材30又は反射部材16に当接させる場合に生じる悪影響が少ない場合には、枠体40(端部414)を光学部材30に当接させてもよい。これにより、光学部材30を枠体40によって支持することができる。   In the present embodiment, as shown in FIG. 4, the auxiliary reflecting member 410 is squeezed at the end 421 of the frame main body 420 in the incident opening 411, so The flatness in the optical axis J direction of the end 414 near the member 30 is relatively low. Therefore, when the end portion 414 is brought into contact with the optical member 30 or the like, it is difficult to make the entire circumference of the end portion 414 contact the optical member 30. Therefore, in the present embodiment, a configuration is adopted in which the frame body 40 (end portion 414) is not brought into contact with the optical member 30. Note that the frame body 40 (end portion 414) may be brought into contact with the optical member 30 when there is little adverse effect when the incident opening 411 is brought into contact with the optical member 30 or the reflecting member 16. Thereby, the optical member 30 can be supported by the frame body 40.

And a cylindrical frame 40 having an emission opening 412 through which incident light is emitted. The lamp body 10 includes an instrument main body 11, a light source 12 attached to the instrument main body 11, and a reflecting member 16 that reflects light from the light source 12 toward the optical member 30. The lamp body 10 is provided with a first locking portion 166 that locks the optical member 30, and the optical member 30 is provided with a first locked portion 311. The optical member 30 is supported by the lamp body 10 by the first locked portion 311 being locked to the first locking portion 166, and when the optical member 30 is viewed in the optical axis J direction of the light source 12, At least a part of the outer edge 315 of the optical member 30 is located outside the incident opening 411.

これにより、光学部材30が照明器具1から離脱することを抑制できる。また、締結部材を用いずに、光学部材30を灯体10に容易に支持させることができる。   Thereby, it can suppress that the optical member 30 detaches | leaves from the lighting fixture 1. FIG. Moreover, the optical member 30 can be easily supported by the lamp body 10 without using a fastening member.

また、本実施の形態に係る照明器具1において、灯体10は、光源12の位置を規制する取付部材13をさらに備え、取付部材13には、反射部材16を係止する第二係止部131が設けられてもよい。さらに、第一係止部166は、反射部材16に設けられ、反射部材16には、第二係止部131に係止される第二被係止部164が設けられ、反射部材16は、第二被係止部164が第二係止部131に係止されることによって取付部材13に支持されてもよい。   Moreover, in the lighting fixture 1 according to the present embodiment, the lamp body 10 further includes an attachment member 13 that regulates the position of the light source 12, and the attachment member 13 has a second engagement portion that engages the reflection member 16. 131 may be provided. Further, the first locking portion 166 is provided on the reflecting member 16, and the reflecting member 16 is provided with a second locked portion 164 that is locked on the second locking portion 131. The second locked portion 164 may be supported by the attachment member 13 by being locked to the second locking portion 131.

これにより、締結部材を用いずに、反射部材16を取付部材13に容易に支持させることができる。   Thereby, the reflection member 16 can be easily supported by the attachment member 13 without using a fastening member.

また、本実施の形態に係る照明器具1において、第一係止部166及び第二係止部131の少なくとも一方は樹脂で形成されてもよい。   Moreover, in the lighting fixture 1 which concerns on this Embodiment, at least one of the 1st latching | locking part 166 and the 2nd latching | locking part 131 may be formed with resin.

これにより、第一係止部166及び第二係止部131の少なくとも一方を容易に形成することができる。   Thereby, at least one of the 1st latching | locking part 166 and the 2nd latching | locking part 131 can be formed easily.

また、本実施の形態に係る照明器具1において、反射部材16を光軸J方向に見た場合に、反射部材16の外縁168は、入射開口部411の外側に位置してもよい。   Moreover, in the lighting fixture 1 according to the present embodiment, when the reflecting member 16 is viewed in the direction of the optical axis J, the outer edge 168 of the reflecting member 16 may be located outside the incident opening 411.

これにより、反射部材16が照明器具1から離脱することを抑制できる。また、反射部材16の外縁168が入射開口部411より外側に位置することにより、Y軸方向負側から照明器具1を見た場合に、入射開口部411の内側には、反射部材16、光学部材30及び光源12だけが見える。つまり、照明器具1の内部の配線などが、照明器具1の外部から見られることを抑制することができる。これにより、ユーザなどが、照明器具1の内部の配線などに触れることを抑制できる。また、照明器具1の内部が見えない構成は、外観デザイン上も好ましい。   Thereby, it can suppress that the reflection member 16 detaches | leaves from the lighting fixture 1. FIG. In addition, since the outer edge 168 of the reflecting member 16 is positioned outside the incident opening 411, when the luminaire 1 is viewed from the Y axis direction negative side, the reflecting member 16 and the optical are located inside the incident opening 411. Only member 30 and light source 12 are visible. That is, it can suppress that the wiring inside the lighting fixture 1 etc. are seen from the exterior of the lighting fixture 1. FIG. Thereby, it can suppress that a user etc. touch the wiring inside the lighting fixture 1, etc. FIG. Moreover, the structure which cannot see the inside of the lighting fixture 1 is preferable also on an external appearance design.

また、本実施の形態に係る照明器具1において、光学部材30はフレネルレンズであってもよい。   In the lighting fixture 1 according to the present embodiment, the optical member 30 may be a Fresnel lens.

光学部材30がフレネルレンズである場合には、光学部材30の厚さが比較的厚くなる。そのため、光学部材30の重量も重くなるため、第一係止部166などに加わる力が大きくなる。したがって、第一係止部166などの破損が生じやすくなるため、本実施の形態に係る照明器具1の構成が特に有効である。   When the optical member 30 is a Fresnel lens, the thickness of the optical member 30 is relatively thick. Therefore, since the weight of the optical member 30 also becomes heavy, the force added to the 1st latching | locking part 166 etc. becomes large. Therefore, the first locking portion 166 and the like are easily damaged, and thus the configuration of the lighting fixture 1 according to the present embodiment is particularly effective.
