In this embodiment, the bent portion 23a is a folded portion formed by folding back the tip portion of the side plate portion 23 in the thickness direction. Therefore, the folded portion 23a is composed of a folded portion and a portion opposite to the folded portion (a non-folded portion). The folded portion of the bent portion 23a can be formed, for example, by curling and rolling up the tip portion of the side plate portion 23. Note that the bent portion 23a is not limited to being formed by curling, but may be formed by hemming or the like. Note that the bent portion 23a formed by curling or hemming bending is formed by being bent inward in the width direction, but is not limited to this, and may be formed by being bent outward in the width direction. Further, the bent portion 23a may not be formed.

In this embodiment, the cover member 30 is a diffusion cover that not only has light-transmitting properties but also has diffusive properties. Therefore, the light from the LED 12 that has entered the cover member 30 passes through the cover member 30 while being diffused (scattering) by the cover member 30 .
　図６及び図７に示すように、カバー部材３０は、さらに、光源部１０が配置されたフレーム２０を覆っている。本実施の形態において、カバー部材３０は、光源部１０が配置されたフレーム２０の全体を覆っている。なお、カバー部材３０は、光源部１０及びフレーム２０と同様に、Ｙ軸方向に長尺状に形成されている。 As shown in FIGS. 6 and 7, the cover member 30 further covers the frame 20 on which the light source section 10 is arranged. In this embodiment, the cover member 30 covers the entire frame 20 in which the light source section 10 is arranged.

The main portion 31 constitutes the outer appearance of the cover member 30. As shown in FIG. 8, the main portion 31 is elongated in the Y-axis direction and shaped like a gutter. The main portion 31 has, for example, a flat, substantially semi-cylindrical shape. Therefore, the main portion 31 has an elongated rectangular open end surface extending in the Y-axis direction. Moreover, the cross-sectional shape of the main portion 31 when cut along the X-axis direction has a curved shape curved in a substantially arc shape. Note that the shape of the main portion 31 is not limited to the R-shape of a bucket, but may be a square shape such as a U-shape, or a square shape with a part of the side surface constricted. .

Specifically, the outer end portion 31a is a portion of the main portion 31 located on the outer side of the attachment portion 33. The outer end 31a of the main portion 31 faces the opening edge 2a1 of the recess 2a of the instrument body 2. Note that the opening edge 2a1 of the recess 2a is a flat surface parallel to the XY plane.
　一対の延設部３２は、厚みが一定で板状の板片である。本実施の形態において、一対の延設部３２は、ＸＺ断面において、カバー部材３０の中心を基準に左右対称に形成されているが、これに限らない。 The pair of extended portions 32 are plate-shaped pieces with a constant thickness. In the present embodiment, the pair of extension parts 32 are formed symmetrically with respect to the center of the cover member 30 in the XZ cross section, but the invention is not limited thereto.

It has an inner extending portion 32b extending toward the side.
　本実施の形態において、外延設部３２ａは、取付部３３よりも外側に位置する部分であり、内延設部３２ｂは、取付部３３よりも内側に位置する部分である。この場合、図３に示すように、外延設部３２ａは、平板状に形成された部分であり、内延設部３２ｂは、フレーム２０の突出部２２を境界にして折れ曲るように形成された部分である。具体的には、内延設部３２ｂは、外延設部３２ａと取付部３３との接続部分から床側に向かって延在する部分と、フレーム２０の突出部２２に対向する部分から先端が天井側に向かって延在する部分とを有する。 In the present embodiment, the outwardly extending portion 32a is a portion located on the outside of the attachment portion 33, and the inwardly extending portion 32b is a portion located on the inside of the attachment portion 33. In this case, as shown in FIG. 3, the outer extending portion 32a is a portion formed in a flat plate shape, and the inner extending portion 32b is formed so as to be bent with the protruding portion 22 of the frame 20 as a boundary. This is the part. Specifically, the inwardly extending portion 32b has a portion that extends toward the floor from a connecting portion between the outwardly extending portion 32a and the mounting portion 33, and a portion that extends toward the ceiling from a portion that faces the protruding portion 22 of the frame 20. and a portion extending toward the side.
　各延設部３２は、主部３１の内面からカバー部材３０の内方に向かって延在している。つまり、各延設部３２は、主部３１の内面からＬＥＤ１２側に向かって延在している。各延設部３２は、主部３１の内面におけるフレーム２０の突出部２２のうち最も床側（第１方向側）に位置する部位よりも天井側（第２方向側）の位置からＬＥＤ側に向かって延在している。本実施の形態において、フレーム２０の突出部２２のうち最も床側に位置する部位は、突出部２２の第１板部２２ａである。したがって、延設部３２は、第１板部２２ａよりも天井側に位置からＬＥＤ１２側に向かって延在している。具体的には、各延設部３２は、主部３１の外側端部３１ａの先端に接続されている。したがって、各延設部３２において、外延設部３２ａが主部３１の外側端部３１ａの先端に接続されており、外延設部３２ａは、主部３１の外側端部３１ａからＬＥＤ１２側に向かって延在している。 Each extending portion 32 extends from the inner surface of the main portion 31 toward the inside of the cover member 30. That is, each extending portion 32 extends from the inner surface of the main portion 31 toward the LED 12 side. Each extension portion 32 extends from a position closer to the ceiling (second direction side) than a portion of the protruding portion 22 of the frame 20 located closest to the floor (first direction side) on the inner surface of the main portion 31 to the LED side. It extends towards. In this embodiment, the portion of the protrusion 22 of the frame 20 that is located closest to the floor is the first plate portion 22a of the protrusion 22. Therefore, the extending portion 32 extends from a position closer to the ceiling than the first plate portion 22a toward the LED 12 side. Specifically, each extending portion 32 is connected to the tip of the outer end portion 31a of the main portion 31. Therefore, in each extending portion 32, the outwardly extending portion 32a is connected to the tip of the outer end 31a of the main portion 31, and the outwardly extending portion 32a extends from the outer end 31a of the main portion 31 toward the LED 12 side.

Further, the outwardly extending portion 32a faces the opening edge 2a1 of the recess 2a. Therefore, the outwardly extending portion 32a is formed so as to straddle the gap G.
　外延設部３２ａにおける開口端縁２ａ１に対向する部分と主部３１の外側端部３１ａとは、取付部３３から外側に突出する突出部を形成している。具体的には、この突出部は、ＸＺ断面において、断面Ｖ字形状に形成されている。なお、外延設部３２ａは、器具本体２の凹部２ａの開口面の幅方向外側端部よりも外側に飛び出していない。具体的には、外延設部３２ａは、凹部２ａの開口端縁２ａ１よりもＹ軸方向の外側に飛び出していない。具体的には、外延設部３２ａと主部３１の外側端部３１ａの接続部分（Ｖ字の頂点）は、器具本体２の傾斜面２ｂとほぼ同一面に存在している。これにより、器具本体２の傾斜面２ｂとカバー部材３０の主部３１の表面とが連続する一つの面となるので、ＬＥＤ照明装置３の意匠性が向上する。 The portion of the outwardly extending portion 32a that faces the opening edge two a1 and the outer end portion 31a of the main portion 31 form a protruding portion that protrudes outward from the mounting portion 33. Specifically, this protrusion is formed to have a V-shaped cross section in the XZ cross section. Note that the externally extending portion 32a does not protrude outward beyond the outer end in the width direction of the opening surface of the recess 2a of the instrument main body 2. Specifically, the outwardly extending portion 32a does not protrude outward in the Y-axis direction beyond the opening edge 2a1 of the recess 2a. Specifically, the connection portion (the apex of the V-shape) between the externally extending portion 32a and the outer end portion 31a of the main portion 31 exists on substantially the same plane as the inclined surface 2b of the instrument body 2. Thereby, the inclined surface 2b of the appliance main body 2 and the surface of the main portion 31 of the cover member 30 become one continuous surface, so that the design of the LED lighting device 3 is improved.
　外延設部３２ａは、器具本体２の凹部２ａの開口端縁２ａ１に当接しうる当たり部である。ＬＥＤ照明装置３が器具本体２の凹部２ａに収納された状態において、外延設部３２ａは、開口端縁２ａ１に当接していてもよいし、開口端縁２ａ１に当接していなくてもよい。つまり、外延設部３２ａと開口端縁２ａ１との間に隙間が存在していてもよいし、外延設部３２ａと開口端縁２ａ１とが密着していてもよい。 The outwardly extending portion 32a is a contact portion that can come into contact with the opening edge 2a1 of the recess 2a of the instrument main body 2. In the state where the LED lighting device 3 is housed in the recess 2a of the appliance main body 2, the externally extending portion 32a may or may not be in contact with the opening edge two a1. That is, a gap may exist between the outwardly extending portion 32a and the opening edge two a1, or the outwardly extending portion 32a and the opening edge two a1 may be in close contact with each other.
　一対の延設部３２の各々は、フレーム２０の突出部２２の少なくとも一部を覆うようにしてＬＥＤ１２側に向かって延在している。本実施の形態では、各延設部３２の内延設部３２ｂがフレーム２０の突出部２２を覆っている。 Each of the pair of extensions 32 extends toward the LED 12 side so as to cover at least a portion of the protrusion 22 of the frame 20. In this embodiment, the inner extending portion 32b of each extending portion 32 covers the protruding portion 22 of the frame 20.

In this embodiment, at least a portion of each extending portion 32 has a shape that follows the protruding portion 22 of the frame 20 . Specifically, the inner extending portion 32b of each extending portion 32 has a shape that follows the protruding portion 22 of the frame 20.
　各延設部３２は、床側に向かって突出するように屈曲している。つまり、各延設部３２は、フレーム２０の突出部２２と同様に、床側に向かって突出する突出部を有するように形成されている。フレーム２０の突出部２２は、この延設部３２の屈曲する部分（突出部分）に向かって突出している。したがって、フレーム２０の突出部２２は、延設部３２の突出部分に嵌るように形成されている。 Each extending portion 32 is bent so as to protrude toward the floor. That is, each extending portion 32 is formed to have a protruding portion that protrudes toward the floor, similar to the protruding portion 22 of the frame 20. The protruding portion 22 of the frame 20 protrudes toward the bent portion (protruding portion) of the extending portion 32. Therefore, the protrusion 22 of the frame 20 is formed to fit into the protrusion of the extension 32.
　また、各延設部３２の少なくとも一部は、フレーム２０に当接しうる。具体的には、各延設部３２の少なくとも一部は、フレーム２０の突出部２２の一部に当接しうる。より具体的には、各延設部３２は、突出部２２における第１板部２２ａ及び第２板部２２ｂに当接しうる。 Furthermore, at least a portion of each extension portion 32 may come into contact with the frame 20. Specifically, at least a portion of each extension portion 32 may abut a portion of the protrusion portion 22 of the frame 20 . More specifically, each extending portion 32 can come into contact with the first plate portion 22a and the second plate portion 22b of the protruding portion 22.
　図３に示すように、本実施の形態において、内延設部３２ｂは、突出部２２の第１板部２２ａに当接しうる第１面部３２ｂ１と、突出部２２の第２板部２２ｂに当接しうる第２面部３２ｂ２とを有する。 As shown in FIG. 3, in this embodiment, the inwardly extending portion 32b has a first surface portion 32b1 that can come into contact with the first plate portion 22a of the protruding portion 22, and a second plate portion 22b of the protruding portion 22. It has a second surface portion 32b2 that can be contacted.
　このように、ＬＥＤ照明装置３が器具本体２の凹部２ａに収納された状態において、各延設部３２の少なくとも一部は、突出部２２に接していてもよいし、突出部２２に接していなくてもよい。例えば、延設部３２における内延設部３２ｂの第１面部３２ｂ１及び第２面部３２ｂ２とフレーム２０における突出部２２の第１板部２２ａ及び第２板部２２ｂとは、接触していてもよいし、接触していなくてもよい。 In this way, in a state where the LED lighting device 3 is housed in the recess 2a of the appliance main body 2, at least a portion of each extension portion 32 may be in contact with the protrusion 22, or may be in contact with the protrusion 22. You don't have to. For example, the first surface portion 32b1 and second surface portion 32b2 of the inner extension portion 32b of the extension portion 32 and the first plate portion 22a and second plate portion 22b of the protrusion portion 22 of the frame 20 may be in contact with each other. However, they do not have to be in contact.
　各延設部３２において、内延設部３２ｂの第１面部３２ｂ１及び第２面部３２ｂ２は、突出部２２の第１板部２２ａ及び第２板部２２ｂと同様に、いずれも平坦である。つまり、内延設部３２ｂの第１面部３２ｂ１及び第２面部３２ｂ２は、平板状である。 In each extending portion 32, the first surface portion 32b1 and the second surface portion 32b2 of the inner extending portion 32b are both flat, similar to the first plate portion 22a and the second plate portion 22b of the protruding portion 22. That is, the first surface portion 32b1 and the second surface portion 32b2 of the inwardly extending portion 32b have a flat plate shape.
　また、内延設部３２ｂにおいて、第１面部３２ｂ１は、フレーム２０の突出部２２の第１板部２２ａと同様に、フレーム２０の主板部２１と平行な平行板部であり、また、第２面部３２ｂ２は、フレーム２０の突出部２２の第２板部２２ｂと同様に、フレーム２０の主板部２１に対して傾斜する傾斜板部である。内延設部３２ｂの第１面部３２ｂ１と突出部２２の第１板部２２ａとは、平行であり、互いに対面している。同様に、内延設部３２ｂの第２面部３２ｂ２と突出部２２の第２板部２２ｂとは、平行であり、互いに対面している。 In addition, in the inward extending portion 32b, the first surface portion 32b1 is a parallel plate portion parallel to the main plate portion 21 of the frame 20, similar to the first plate portion 22a of the protruding portion 22 of the frame 20, and the second surface portion 32b1 is a parallel plate portion parallel to the main plate portion 21 of the frame 20. The surface portion 32b2 is an inclined plate portion that is inclined with respect to the main plate portion 21 of the frame 20, similarly to the second plate portion 22b of the protruding portion 22 of the frame 20. The first surface portion 32b1 of the inwardly extending portion 32b and the first plate portion 22a of the protruding portion 22 are parallel to each other and face each other. Similarly, the second surface portion 32b2 of the inwardly extending portion 32b and the second plate portion 22b of the protruding portion 22 are parallel and face each other.
　本実施の形態において、各延設部３２の少なくとも一部は、突出部２２に接している。具体的には、各延設部３２における内延設部３２ｂの第１面部３２ｂ１と突出部２２の第１板部２２ａとは、接触している。また、各延設部３２における内延設部３２ｂの第２面部３２ｂ２と突出部２２の第２板部２２ｂとは、接触している。 In this embodiment, at least a portion of each extending portion 32 is in contact with the protruding portion 22. Specifically, the first surface portion 32b1 of the inner extending portion 32b of each extending portion 32 and the first plate portion 22a of the protruding portion 22 are in contact with each other. Further, the second surface portion 32b2 of the inner extending portion 32b of each extending portion 32 and the second plate portion 22b of the protruding portion 22 are in contact with each other.
　各延設部３２の先端は、フレーム２０の突出部２２よりもフレーム２０の中央側に位置している。つまり、各延設部３２の先端は、突出部２２の第１板部２２ａ、第２板部２２ｂ及び第３板部２２ｃよりもフレーム２０の中央側に位置している。 The tip of each extending portion 32 is located closer to the center of the frame 20 than the protruding portion 22 of the frame 20. That is, the tip of each extending portion 32 is located closer to the center of the frame 20 than the first plate portion 22a, second plate portion 22b, and third plate portion 22c of the protruding portion 22.
　延設部３２は、先端が基板１１に向かって延在するように形成されている。具体的には、延設部３２の内延設部３２ｂが、基板１１に向かって基板１１側に傾斜するように形成されている。なお、内延設部３２ｂは、傾斜せずに、外延設部３２ａと同様に、基板１１と平行に延在していてもよい。 The extending portion 32 is formed such that its tip extends toward the substrate 11. Specifically, the inner extending portion 32b of the extending portion 32 is formed so as to be inclined toward the substrate 11 toward the substrate 11. Note that the inner extending portion 32b may extend parallel to the substrate 11, like the outer extending portion 32a, without being inclined.
　Ｚ軸方向において、延設部３２の先端は、基板１１と重なっている。本実施の形態において、延設部３２の先端は、基板１１に接している。具体的には、延設部３２の内延設部３２ｂの先端が基板１１の主面に接している。これにより、カバー部材３０の取付部３３とフレーム２０の側板部２３との間の隙間から虫が侵入しても、カバー部材３０の主部３１とフレーム２０の主板部２１との間の空間にまで虫が侵入することを抑制することができる。また、延設部３２によって基板１１を押さえ付けることで、基板１１が取り付けられたフレーム２０が床側にずれることを抑制することができる。さらに、基板１１をフレーム２０に接着剤等で接着固定した場合に仮に接着剤が剥がれたとしても、フレーム２０から離脱する基板１１は、延設部３２によって支持されることになる。つまり、基板１１が落下することを防止することができる。 In the Z-axis direction, the tip of the extension portion 32 overlaps with the substrate 11. In this embodiment, the tip of the extending portion 32 is in contact with the substrate 11 . Specifically, the tip of the inner extending portion 32b of the extending portion 32 is in contact with the main surface of the substrate 11. As a result, even if an insect enters through the gap between the attachment part 33 of the cover member 30 and the side plate part 23 of the frame 20, it will not be able to enter the space between the main part 31 of the cover member 30 and the main plate part 21 of the frame 20. It is possible to prevent insects from invading. Further, by pressing the board 11 with the extension portion 32, it is possible to suppress the frame 20 to which the board 11 is attached from shifting toward the floor. Further, even if the adhesive is peeled off when the substrate 11 is adhesively fixed to the frame 20 using an adhesive or the like, the substrate 11 detached from the frame 20 will be supported by the extension portion 32. In other words, it is possible to prevent the substrate 11 from falling.
　各延設部３２は、ＬＥＤ１２の照射角（例えば１／２ビーム角）よりも外側に位置しているとよい。例えば、ＬＥＤ１２の光が直接延設部３２に入射する場合は、ＬＥＤ１２の照射角よりも外側に延設部３２を配置することが望ましい。これにより、ＬＥＤ１２から出射した光のカバー部材３０での損失を少なくして、ＬＥＤ１２から出射した光の多くをカバー部材３０を透過させて外部に出射させることができる。つまり、カバー部材３０の光取り出し効率を向上させることができる。 It is preferable that each extension part 32 is located outside the irradiation angle (for example, 1/2 beam angle) of the LED 12. For example, when the light of the LED 12 is directly incident on the extension part 32, it is desirable to arrange the extension part 32 outside the irradiation angle of the LED 12. Thereby, the loss of the light emitted from the LED 12 at the cover member 30 can be reduced, and most of the light emitted from the LED 12 can be transmitted through the cover member 30 and emitted to the outside. In other words, the light extraction efficiency of the cover member 30 can be improved.
　各延設部３２とフレーム２０との間には、空間が存在している。具体的には、各延設部３２とフレーム２０の主板部２１との間に空間が存在している。この空間には、各種部品をネジ止めしたときネジの足又はネジの頭を収納したり、フレーム２０と他の金属部品とをかしめたときのカシメ部を収納したりすることができる。例えば、図３に示すように、この空間には、電源装置４とフレーム２０とを固定するためのネジ５０のネジの足が収納されている。 A space exists between each extension portion 32 and the frame 20. Specifically, a space exists between each extension portion 32 and the main plate portion 21 of the frame 20. This space can store the feet of the screws or the heads of the screws when various parts are screwed together, or can store the caulking parts when the frame 20 and other metal parts are caulked together. For example, as shown in FIG. 3, the legs of the screws 50 for fixing the power supply device 4 and the frame 20 are housed in this space.
　また、各延設部３２とフレーム２０との間の空間には、機能部品が収納されていてもよいし、器具内電線が収納されていてもよい。なお、機能部品は、例えば機能拡張モジュールである。機能拡張モジュールは、一例として、人感センサや明るさセンサの各種センサを備えるセンサユニット、無線信号を受信するアンテナ及び制御回路を有する無線モジュール、赤外線信号を受信する受光素子及び制御回路を有する赤外線モジュール、又は、基板１１に実装されたＬＥＤ１２（第１光源）とは別の第２光源等である。無線信号又は赤外線信号は、例えば、ＬＥＤ１２を点消灯したり調光・調色したりするためのリモコン信号、又は、ＬＥＤ照明装置３の各種設定を行うための設定信号等である。また、第２光源は、モニタ表示用の光源、カバー部材３０から出射する照明光の配光を制御するための光源（例えばワイド配光にするための光源）、演出するためのカラー光源（例えば、赤色、青色及び緑色等のＬＥＤ光源）、又は、非常時に点灯する非常用光源等である。なお、第２光源として非常用光源を用いる場合は、第２光源を覆うカバー及び／又はカバー部材３０は、ガラス等の難燃性材料によって構成されているとよい。 Furthermore, functional components or internal electric wires may be stored in the space between each extension portion 32 and the frame 20. Note that the functional component is, for example, a function expansion module. Examples of the function expansion module include a sensor unit that includes various sensors such as a human sensor and a brightness sensor, a wireless module that has an antenna that receives wireless signals and a control circuit, and an infrared module that has a light receiving element that receives infrared signals and a control circuit. It is a second light source different from the LED 12 (first light source) mounted on the module or the substrate 11, or the like. The wireless signal or infrared signal is, for example, a remote control signal for turning on/off the LED 12 or adjusting the brightness/color, or a setting signal for making various settings of the LED lighting device 3. Further, the second light source includes a light source for monitor display, a light source for controlling the light distribution of the illumination light emitted from the cover member 30 (for example, a light source for wide light distribution), and a color light source for producing effects (for example, , red, blue, and green LED light sources), or emergency light sources that are turned on in an emergency. Note that when an emergency light source is used as the second light source, the cover and/or cover member 30 that covers the second light source is preferably made of a flame-retardant material such as glass.
　一対の取付部３３は、フレーム２０に取り付けられる部分であり、カバー部材３０における一対の脚部として形成されている。具体的には、一対の取付部３３は、フレーム２０の一対の側板部２３に取り付けられる。 The pair of attachment parts 33 are parts that are attached to the frame 20 and are formed as a pair of leg parts of the cover member 30. Specifically, the pair of attachment parts 33 are attached to the pair of side plate parts 23 of the frame 20.
　一対の取付部３３の各々は、延設部３２の一部から天井側に向かって延在している。一対の取付部３３のＺ軸方向の長さは、同じである。なお、図７に示すように、一対の取付部３３の各々は、Ｙ軸方向に沿って長尺状に形成されている。一対の取付部３３のＹ軸方向の長さも互いに同じである。 Each of the pair of attachment parts 33 extends from a part of the extension part 32 toward the ceiling. The lengths of the pair of attachment portions 33 in the Z-axis direction are the same. Note that, as shown in FIG. 7, each of the pair of attachment parts 33 is formed in an elongated shape along the Y-axis direction. The lengths of the pair of attachment portions 33 in the Y-axis direction are also the same.
　図６及び図７に示すように、一対の取付部３３の各々の先端部における幅方向（Ｘ軸方向）の内側には凹部３３ａが形成されている。この凹部３３ａにフレーム２０の側板部２３の先端部に設けられた折曲部２３ａが嵌め込まれることで、カバー部材３０の一対の取付部３３とフレーム２０の一対の側板部２３とが互いに係止して固定される。これにより、カバー部材３０の一対の取付部３３は、フレーム２０を抱え込むようにしてフレーム２０に固定される。 As shown in FIGS. 6 and 7, a recess 33a is formed inside the width direction (X-axis direction) at the tip of each of the pair of attachment portions 33. By fitting the bent portion 23a provided at the tip of the side plate portion 23 of the frame 20 into the recess 33a, the pair of attachment portions 33 of the cover member 30 and the pair of side plate portions 23 of the frame 20 are locked to each other. and fixed. Thereby, the pair of attachment parts 33 of the cover member 30 are fixed to the frame 20 so as to embrace the frame 20.
　なお、フレーム２０の側板部２３とカバー部材３０の取付部３３とをネジで固定してもよい。このネジは、側板部２３と取付部３３とが重なった部分に、取付部３３の外側からねじ込まれる。 Note that the side plate portion 23 of the frame 20 and the mounting portion 33 of the cover member 30 may be fixed with screws. This screw is screwed into a portion where the side plate portion 23 and the attachment portion 33 overlap from the outside of the attachment portion 33.
　また、本実施の形態において、凹部３３ａは、先端が折り返されるように形成されており、凹部３３ａの断面形状は、略コの字状又は略Ｕ字状である。なお、凹部３３ａの形状は、これに限るものではない。例えば、凹部３３ａは、断面形状がＬ字状であって先端が折り返されないように形成されていてもよいし、断面形状がＶ字状であってもよいし、断面形状が円弧状であってもよい。ただし、凹部３３ａは、折曲部２３ａが嵌め込まれる形状であるとよい。 Furthermore, in this embodiment, the recess 33a is formed so that the tip thereof is folded back, and the cross-sectional shape of the recess 33a is approximately U-shaped or approximately U-shaped. Note that the shape of the recess 33a is not limited to this. For example, the recess 33a may have an L-shape in cross-section and not be folded back, or may have a V-shape in cross-section, or may have an arc-shape in cross-section. It's okay. However, it is preferable that the recessed portion 33a has a shape into which the bent portion 23a is fitted.

In this embodiment, the cover member 30 is made of a translucent resin material. In this case, the cover member 30 may be a milky white cover member in which a light diffusing material is dispersed. Such a cover member 30 can be produced by resin-molding a translucent resin material mixed with a light diffusing material into a predetermined shape. As the light diffusing material, light reflective fine particles such as silica particles can be used.
　なお、カバー部材３０としては、内部に光拡散材を分散させるのではなく、透明カバーの表面（内面又は外面）に光拡散材等を含む乳白色の光拡散膜を形成することによって構成されていてもよい。また、カバー部材３０は、光拡散材を用いるのではなく、拡散加工を施すことによって光拡散性を有するように構成されていてもよい。例えば、カバー部材３０は、シボ加工等の表面処理を施すことによって透明カバーの表面に微小凹凸を形成したり、透明カバーの表面にドットパターンを印刷したりすることによって光拡散性を有するように構成されていてもよい。なお、カバー部材３０は、拡散加工する場合であっても、光拡散性を高めるために、さらに光拡散材を含有させてもよい。 The cover member 30 is constructed by forming a milky-white light diffusing film containing a light diffusing material on the surface (inner or outer surface) of the transparent cover, rather than dispersing the light diffusing material inside. Good too. Moreover, the cover member 30 may be configured to have light diffusing properties by performing a diffusion process instead of using a light diffusing material. For example, the cover member 30 can be made to have light diffusing properties by forming minute irregularities on the surface of the transparent cover by performing a surface treatment such as texturing, or by printing a dot pattern on the surface of the transparent cover. may be configured. Note that even when the cover member 30 is subjected to diffusion processing, it may further contain a light diffusing material in order to improve light diffusivity.

Therefore, the main portion 31, the extending portion 32, and the attachment portion 33 are made of the same material. Moreover, although the main part 31, the extending part 32, and the attachment part 33 all have the same thickness, the thickness is not limited to this.

Thereby, it is possible to suppress dust, insects, etc. from entering the inside of the cylindrical body constituted by the frame 20 and the cover member 30. Note that the end cap 40 does not completely close the open end of the cylindrical body composed of the frame 20 and the cover member 30, and even if there is some gap between the end cap 40 and the frame 20. good.

　図３に示すように、引っ掛け金具５は、フレーム２０における主板部２１の天井側に配置されている。引っ掛け金具５は、板金製の板部材である。引っ掛け金具５は、フレーム２０の主板部２１の端部に固定されている。一例として、引っ掛け金具５は、ネジ等の固定部材によってフレーム２０の主板部２１に固定されており、フレーム２０の主板部２１から外側にはみ出すように延在している。引っ掛け金具５は、器具本体２に引っ掛けられる。本実施の形態では、器具本体２の凹部２ａの内壁面にスリット２ｃ（図２参照）が設けられており、引っ掛け金具５は、このスリット２ｃに引っ掛けられる。 As shown in FIG. 3, the hook 5 is arranged on the ceiling side of the main plate portion 21 of the frame 20. The hook 5 is a plate member made of sheet metal. The hook 5 is fixed to the end of the main plate 21 of the frame 20. As an example, the hook 5 is fixed to the main plate 21 of the frame 20 with a fixing member such as a screw, and extends outward from the main plate 21 of the frame 20. The hooking fitting 5 is hooked onto the instrument body 2. In this embodiment, a slit 2c (see FIG. 2) is provided on the inner wall surface of the recess 2a of the instrument main body 2, and the hook 5 is hooked into the slit 2c.
　弾性保持部材６は、フレーム２０における主板部２１の天井側に配置されている。弾性保持部材６は、例えばキックバネ等のスプリングである。弾性保持部材６は、フレーム２０の主板部２１の天井側面において、主板部２１の端部に固定されている。弾性保持部材６は、フレーム２０の主板部２１の幅方向において、引っ掛け金具５とは反対側に固定されている。弾性保持部材６は、ネジ等の固定部材によってフレーム２０の主板部２１に固定されている。具体的には、弾性保持部材６は、取付ネジによってフレーム２０に固定された保持金具６ｃ（図６参照）に固定されている。弾性保持部材６は、器具本体２に着脱可能に取り付けられる。本実施の形態において、弾性保持部材６は、器具本体２に固定された受け金具７に着脱可能に係止されている。 The elastic holding member 6 is arranged on the ceiling side of the main plate portion 21 of the frame 20. The elastic holding member 6 is, for example, a spring such as a kick spring. The elastic holding member 6 is fixed to the end of the main plate 21 of the frame 20 on the ceiling side surface of the main plate 21 . The elastic holding member 6 is fixed to the side opposite to the hook 5 in the width direction of the main plate portion 21 of the frame 20 . The elastic holding member 6 is fixed to the main plate portion 21 of the frame 20 with a fixing member such as a screw.

The elastic holding member 6 is removably attached to the instrument body 2. In this embodiment, the elastic holding member 6 is removably locked to a receiving metal fitting 7 fixed to the instrument main body 2.
　なお、図２に示すように、引っ掛け金具５及び弾性保持部材６は、フレーム２０の長手方向の両端部に２つずつ設けられているが、これに限らない。また、引っ掛け金具５及び弾性保持部材６は、フレーム２０の主板部２１の短手方向に対向する位置に設けられているが、これに限らない。 Note that, as shown in FIG. 2, two hooks 5 and two elastic holding members 6 are provided at both ends of the frame 20 in the longitudinal direction, but the present invention is not limited thereto. Furthermore, although the hooking fittings 5 and the elastic holding members 6 are provided at positions facing each other in the lateral direction of the main plate portion 21 of the frame 20, the present invention is not limited thereto.
　ここで、ＬＥＤ照明装置３を器具本体２に取り付けるときの取付方法について、図９を用いて説明する。図９は、実施の形態に係るＬＥＤ照明器具１において、ＬＥＤ照明装置３を器具本体２に取り付けるときの取付方法を説明するための図である。 Here, a method of attaching the LED lighting device 3 to the fixture main body 2 will be explained using FIG. 9. FIG. 9 is a diagram for explaining an attachment method when attaching the LED lighting device 3 to the appliance main body 2 in the LED lighting appliance 1 according to the embodiment.
　天井１００に設置された器具本体２にＬＥＤ照明装置３を取り付ける場合、まず、図９の（ａ）に示すように、器具本体２に設けられたスリット２ｃ（図２参照）に引っ掛け金具５を引っ掛けてＬＥＤ照明装置３を片持ち状態で吊り下げるとともに、キックバネである弾性保持部材６の一方の端部を器具本体２に固定された受け金具７に係止させる。 When attaching the LED lighting device 3 to the fixture body 2 installed on the ceiling 100, first, as shown in FIG. While hanging the LED lighting device 3 in a cantilevered state, one end of the elastic holding member 6, which is a kick spring, is latched to a receiving metal fitting 7 fixed to the instrument body 2.
　次に、図９の（ｂ）に示すように、引っ掛け金具５をスリット２ｃの奥に押し込みながら引っ掛け金具５を支点としてＬＥＤ照明装置３を回転させることでＬＥＤ照明装置３を器具本体２の凹部２ａ内に押し上げていく。 Next, as shown in FIG. 9(b), the LED lighting device 3 is moved into the recess of the device body 2 by rotating the LED lighting device 3 using the hook 5 as a fulcrum while pushing the hook 5 deep into the slit 2c. Push it up into 2a.
　そして、ＬＥＤ照明装置３を回転させてＬＥＤ照明装置３を器具本体２の凹部２ａに押し込むことで、図９の（ｃ）に示すように、ＬＥＤ照明装置３を器具本体２の凹部２ａに嵌め込むことができる。これにより、ＬＥＤ照明装置３を器具本体２に取り付けることができる。 Then, by rotating the LED lighting device 3 and pushing the LED lighting device 3 into the recess 2a of the fixture main body 2, the LED lighting device 3 is fitted into the recess 2a of the fixture main body 2, as shown in FIG. 9(c). can be included. Thereby, the LED lighting device 3 can be attached to the appliance main body 2.
　なお、ＬＥＤ照明装置３を器具本体２から取り外す際は、上記とは逆の動作をすることで、ＬＥＤ照明装置３を器具本体２から取り外すことができる。例えば、ＬＥＤ照明装置３を引き下げながら回転させることで、ＬＥＤ照明装置３を器具本体２から取り外すことができる。 Note that when removing the LED lighting device 3 from the fixture main body 2, the LED lighting device 3 can be removed from the fixture main body 2 by performing the operation opposite to the above. For example, the LED lighting device 3 can be removed from the appliance main body 2 by rotating the LED lighting device 3 while pulling it down.
　以上説明したように、本実施の形態に係るＬＥＤ照明装置３及びＬＥＤ照明器具１は、少なくともフレーム２０とカバー部材３０とを備えており、フレーム２０は、フレーム２０の短手方向における主板部２１の両側に位置し且つ主板部２１よりも床側（第１方向側）に位置する板部として第１板部２２ａ及び／又は第２板部２２ｂを有し、カバー部材３０は、ＬＥＤ１２と対向する面を有する主部３１と、主部３１の内面からＬＥＤ１２側に向かって突出する延設部３２とを有する。そして、延設部３２は、フレーム２０の第１板部２２ａ及び／又は第２板部２２ｂに当接しうる面部として第１面部３２ｂ１及び／又は第２面部３２ｂ２を有している。 As explained above, the LED lighting device 3 and the LED lighting fixture 1 according to the present embodiment include at least the frame 20 and the cover member 30, and the frame 20 includes the main plate portion 21 in the transverse direction of the frame 20. The cover member 30 has a first plate part 22a and/or a second plate part 22b as the plate parts located on both sides of the main plate part 21 and on the floor side (first direction side), and the cover member 30 faces the LED 12. The LED 12 has a main part 31 having a side surface, and an extending part 32 that protrudes from the inner surface of the main part 31 toward the LED 12 side. The extending portion 32 has a first surface portion 32b1 and/or a second surface portion 32b2 that can come into contact with the first plate portion 22a and/or the second plate portion 22b of the frame 20.
　このように、本実施の形態に係るＬＥＤ照明装置３では、フレーム２０の板部である第１板部２２ａ及び／又は第２板部２２ｂと、カバー部材３０の面部である第１面部３２ｂ１及び／又は第２面部３２ｂ２とが、点ではなく面で当接しうる構成になっている。これにより、フレーム２０とカバー部材３０が強固に固定されるので、高い強度を有するＬＥＤ照明装置３を得ることができる。具体的には、ＬＥＤ照明装置３を器具本体２に取り付けたり器具本体２から取り外したりする際にＬＥＤ照明装置３が変形しない程度の十分な強度を確保することができる。 As described above, in the LED lighting device 3 according to the present embodiment, the first plate part 22a and/or the second plate part 22b, which are the plate parts of the frame 20, and the first surface part 32b1, which is the surface part of the cover member 30, /or the second surface portion 32b2 is configured to abut at a surface rather than at a point. Thereby, the frame 20 and the cover member 30 are firmly fixed, so that the LED lighting device 3 having high strength can be obtained. Specifically, sufficient strength can be ensured to prevent the LED lighting device 3 from deforming when the LED lighting device 3 is attached to or removed from the device body 2.
　また、本実施の形態に係るＬＥＤ照明装置３及びＬＥＤ照明器具１は、少なくともフレーム２０とカバー部材３０とを備えており、フレーム２０が、床側に突出する突出部２２を有し、カバー部材３０が、主部３１の内面における突出部２２のうち最も床側（第１方向側）に位置する部位よりも天井側（第２方向側）の位置から突出部２２の少なくとも一部を覆うようにしてＬＥＤ１２側に向かって延在する延設部３２を有している。 Further, the LED lighting device 3 and the LED lighting fixture 1 according to the present embodiment include at least a frame 20 and a cover member 30, and the frame 20 has a protrusion 22 that protrudes toward the floor, and the cover member 30 covers at least a portion of the protruding portion 22 from a position closer to the ceiling (on the second direction side) than a portion of the protruding portion 22 on the inner surface of the main portion 31 that is located closest to the floor (on the first direction side). It has an extending portion 32 that extends toward the LED 12 side.
　床側に突出する突出部２２をフレーム２０に設けると、カバー部材３０の外側端部３１ａにＬＥＤ１２の光が届きにくくなり、カバー部材３０の幅方向（短手方向）の中央部分と比べてカバー部材３０の外側端部３１ａが暗くなる。しかしながら、上記のように延設部３２を形成することで、図１０に示すように、カバー部材３０の外側端部３１ａの近傍において、フレーム２０の突出部２２よりも外側に天井側に向かって広がる空間領域を形成することができる。これにより、床側に突出する突出部２２をフレーム２０に設けたとしても、ＬＥＤ１２から出射した光のうちカバー部材３０の主部３１を透過せずに主部３１の内面で反射した光を、カバー部材３０の外側端部３１ａの近傍に形成された空間領域にまで回り込ませることができる。この結果、ＬＥＤ１２から出射した光をカバー部材３０の主部３１の外側端部３１ａにまで十分に行きわたらせることができるので、カバー部材３０の主部３１の外側端部３１ａの近傍まで十分に光らせることができる。したがって、幅方向（Ｘ軸方向）の全体にわたってカバー部材３０の主部３１を光らせることができるので、カバー部材３０の幅方向の端部が暗くなることを抑制することができる。つまり、フレーム２０の突出部２２によるカバー部材３０の幅方向の端部の暗がりを低減することができる。 When the frame 20 is provided with the protrusion 22 that protrudes toward the floor, the light from the LED 12 becomes difficult to reach the outer end 31a of the cover member 30, and the cover becomes more difficult to reach than the center part of the cover member 30 in the width direction (short direction). The outer end 31a of the member 30 is darkened. However, by forming the extension part 32 as described above, as shown in FIG. It is possible to form an expanding spatial region. As a result, even if the frame 20 is provided with the protruding part 22 that protrudes toward the floor, the light that is emitted from the LED 12 and is reflected on the inner surface of the main part 31 without passing through the main part 31 of the cover member 30 can be It can be made to wrap around the space region formed near the outer end 31a of the cover member 30. As a result, the light emitted from the LED 12 can sufficiently spread to the outer end 31a of the main portion 31 of the cover member 30, so that the light emitted from the LED 12 can sufficiently reach the vicinity of the outer end 31a of the main portion 31 of the cover member 30. It can be made to shine. Therefore, since the main portion 31 of the cover member 30 can be illuminated throughout the width direction (X-axis direction), it is possible to suppress the end portions of the cover member 30 in the width direction from becoming dark. In other words, it is possible to reduce darkness at the ends of the cover member 30 in the width direction due to the protruding portions 22 of the frame 20.
　特に、本実施の形態に係るＬＥＤ照明装置３では、フレーム２０の突出部２２に設けた板部に対してカバー部材３０の延設部３２の面部が当接しうる状態になっているので、フレーム２０とカバー部材３０とが強固に固定されている。したがって、本実施の形態に係るＬＥＤ照明装置３によれば、カバー部材３０の外側端部３１ａの暗がりを低減することと高い強度を得ることとの両立を図ることができる。 In particular, in the LED lighting device 3 according to the present embodiment, the surface portion of the extending portion 32 of the cover member 30 can come into contact with the plate portion provided on the protruding portion 22 of the frame 20, so that the frame 20 and cover member 30 are firmly fixed. Therefore, according to the LED lighting device 3 according to the present embodiment, it is possible to reduce the darkness of the outer end portion 31a of the cover member 30 and to obtain high intensity at the same time.
　また、本実施の形態に係るＬＥＤ照明装置３及びＬＥＤ照明器具１は、少なくともフレーム２０とカバー部材３０とを備えており、カバー部材３０の延設部３２が外延設部３２ａと内延設部３２ｂとを有しており、外延設部３２ａは、Ｚ軸方向において、カバー部材３０と器具本体２の凹部２ａの内面との間に隙間Ｇと重なる部位を有する。 Further, the LED lighting device 3 and the LED lighting fixture 1 according to the present embodiment include at least a frame 20 and a cover member 30, and the extending portion 32 of the cover member 30 is arranged between an outer extending portion 32a and an inner extending portion. 32b, and the outwardly extending portion 32a has a portion that overlaps with the gap G between the cover member 30 and the inner surface of the recess 2a of the instrument body 2 in the Z-axis direction.
　この構成により、カバー部材３０の主部３１の外側端部３１ａの近傍まで十分に光らせることができる。これにより、幅方向（Ｘ軸方向）の全体にわたってカバー部材３０の主部３１を光らせることができる。したがって、幅方向（Ｘ軸方向）の全体にわたってカバー部材３０の主部３１を光らせることができるので、カバー部材３０の幅方向の端部が暗くなることを抑制することができる。 With this configuration, it is possible to sufficiently illuminate the vicinity of the outer end portion 31a of the main portion 31 of the cover member 30. Thereby, the main portion 31 of the cover member 30 can be illuminated throughout the width direction (X-axis direction). Therefore, since the main portion 31 of the cover member 30 can be illuminated throughout the width direction (X-axis direction), it is possible to suppress the end portions of the cover member 30 in the width direction from becoming dark.
　特に、本実施の形態におけるＬＥＤ照明装置３は、床側に突出する突出部２２をフレーム２０に設けたことでカバー部材３０の幅方向の端部が暗くなりやすい構造になっているが、延設部３２の外延設部３２ａを隙間Ｇと重なるようにすることで、カバー部材３０の幅方向の端部が暗くなることを効果的に抑制できる。 In particular, the LED lighting device 3 according to the present embodiment has a structure in which the ends of the cover member 30 in the width direction tend to become dark due to the provision of the protrusion 22 on the frame 20 that protrudes toward the floor. By making the outwardly extending portion 32a of the extending portion 32 overlap the gap G, it is possible to effectively suppress the end portions of the cover member 30 in the width direction from becoming dark.
　しかも、本実施の形態に係るＬＥＤ照明装置３では、上記のように、カバー部材３０の外側端部３１ａの近傍において、フレーム２０の突出部２２よりも外側に天井側に向かって広がる空間領域が形成されている。これにより、ＬＥＤ１２から出射した光をこの空間領域に回り込ませることができる。したがって、カバー部材３０の主部３１の外側端部３１ａが暗く感じることを一層抑制することができる。 Moreover, in the LED lighting device 3 according to the present embodiment, as described above, in the vicinity of the outer end portion 31a of the cover member 30, a spatial region that extends outward from the protruding portion 22 of the frame 20 toward the ceiling side is formed. It is formed. Thereby, the light emitted from the LED 12 can be made to go around this spatial area. Therefore, it is possible to further prevent the outer end 31a of the main portion 31 of the cover member 30 from feeling dark.
　（変形例）
　以下、ＬＥＤ照明装置及びＬＥＤ照明器具の変形例について、図面を用いて説明する。これらの変形例についても、上記実施の形態と同様の効果を得ることができる。なお、以下の変形例では、上記実施の形態と異なる点を中心に説明する。 (Modified example)
Hereinafter, modified examples of the LED lighting device and the LED lighting fixture will be described using the drawings. These modified examples can also provide the same effects as the above embodiments. Note that in the following modified examples, points different from the above embodiment will be mainly explained.
　（変形例１）
　図１１Ａは、変形例１に係るＬＥＤ照明装置３Ａの断面図である。 (Modification 1)
FIG. 11A is a cross-sectional view of an LED lighting device 3A according to Modification 1.
　上記実施の形態におけるＬＥＤ照明装置３では、カバー部材３０は、１種類の樹脂材料によって構成されていたが、本変形例に係るＬＥＤ照明装置３Ａでは、カバー部材３０Ａは、２種類以上の材料によって構成されている。具体的には、カバー部材３０Ａは、２種類の材料によって構成されている。本変形例では、カバー部材３０Ａの延設部３２Ａの少なくとも一部は、主部３１とは異なる材料によって形成されている。 In the LED lighting device 3 in the above embodiment, the cover member 30 is made of one type of resin material, but in the LED lighting device 3A according to this modification, the cover member 30A is made of two or more types of materials. It is configured. Specifically, the cover member 30A is made of two types of materials. In this modification, at least a portion of the extending portion 32A of the cover member 30A is formed of a material different from that of the main portion 31.
　図１１Ａに示すように、本変形例に係るＬＥＤ照明装置３Ａでは、主部３１及び取付部３３と延設部３２Ａとが異なる樹脂材料によって構成されている。具体的には、主部３１、取付部３３、延設部３２Ａの外延設部３２ａ、延設部３２Ａの内延設部３２ｂの第２面部３２ｂ２と、延設部３２Ａの内延設部３２ｂの第１面部３２ｂ１とが異なる樹脂材料によって構成されている。 As shown in FIG. 11A, in the LED lighting device 3A according to this modification, the main portion 31, the mounting portion 33, and the extension portion 32A are made of different resin materials. Specifically, the main portion 31, the attachment portion 33, the outer extending portion 32a of the extending portion 32A, the second surface portion 32b2 of the inner extending portion 32b of the extending portion 32A, and the inner extending portion 32b of the extending portion 32A. The first surface portion 32b1 is made of a different resin material.
　この場合、例えば、主部３１、取付部３３、延設部３２Ａの外延設部３２ａ及び延設部３２Ａの内延設部３２ｂの第２面部３２ｂ２を透光性樹脂材料で構成し、延設部３２Ａの内延設部３２ｂの第１面部３２ｂ１を白色又は乳白の樹脂材料によって構成することができる。このようなカバー部材３０は、２色成形により形成することができる。 In this case, for example, the main part 31, the attachment part 33, the second surface part 32b2 of the outer extension part 32a of the extension part 32A and the inner extension part 32b of the extension part 32A are made of a translucent resin material, and the extension part 32A is made of a transparent resin material. The first surface portion 32b1 of the inwardly extending portion 32b of the portion 32A can be made of a white or milky white resin material. Such a cover member 30 can be formed by two-color molding.
　このように、延設部３２Ａの内延設部３２ｂの少なくとも一部を白色又は乳白の樹脂材料によって構成することで、内延設部３２ｂに反射機能を持たせることができる。これにより、ＬＥＤ１２から出射する光のうち延設部３２Ａの内延設部３２ｂに到達する光を内延設部３２ｂで反射させて主部３１に入射させることができる。この場合、本変形例のように、内延設部３２ｂの第１面部３２ｂ１を天井側に向かって斜めに傾斜させることで、ＬＥＤ１２の光を鉛直方向に向けて集光させることができるとともに、ＬＥＤ照明装置３Ａの光取り出し効率を向上させることができる。このように、内延設部３２ｂに反射機能を持たせることで、ＬＥＤ照明器具の直下照度を向上させることができるので、ＬＥＤ照明器具１の設置台数を低減することができる。 In this way, by configuring at least a portion of the inner extending portion 32b of the extending portion 32A with a white or milky white resin material, the inner extending portion 32b can have a reflective function. Thereby, among the light emitted from the LED 12, the light that reaches the inner extending portion 32b of the extending portion 32A can be reflected by the inner extending portion 32b and made to enter the main portion 31. In this case, as in this modification, by tilting the first surface portion 32b1 of the inner extension portion 32b toward the ceiling, the light from the LED 12 can be focused in the vertical direction, and The light extraction efficiency of the LED lighting device 3A can be improved. In this way, by providing the inward extension portion 32b with a reflective function, the illuminance directly below the LED lighting equipment can be improved, so the number of installed LED lighting equipment 1 can be reduced.
　なお、延設部３２Ａの反射率を主部３１の反射率よりも高くすることで、上記のように光取り出し効率を向上させることができるが、延設部３２Ａの反射率をフレーム２０の反射率よりも高くしてもよい。これにより、光取り出し効率を向上させることができるとともに、フレーム２０を塗装レスにすることができる。つまり、フレーム２０に反射塗装を施す必要がなくなる。また、延設部３２Ａの反射率を基板１１の反射率よりも高くしてもよい。これにより、光取り出し効率を向上させることができるとともに、基板１１をレジストレスにすることができる。つまり、基板１１の表面に反射目的の白レジストを形成する必要がなくなる。 Note that by making the reflectance of the extended portion 32A higher than that of the main portion 31, the light extraction efficiency can be improved as described above. It may be higher than the rate. Thereby, the light extraction efficiency can be improved and the frame 20 can be made without painting. In other words, there is no need to apply reflective coating to the frame 20. Further, the reflectance of the extended portion 32A may be higher than the reflectance of the substrate 11. Thereby, the light extraction efficiency can be improved and the substrate 11 can be made resistless. In other words, there is no need to form a white resist for reflection purposes on the surface of the substrate 11.
　また、図１１Ａでは、カバー部材３０Ａにおける２色成形の境界を、延設部３２Ａの内延設部３２ｂにおける第１面部３２ｂ１と第２面部３２ｂ２との接続部としたが、これに限らない。例えば、図１１Ｂ及び図１１Ｃに示すように、カバー部材３０Ａにおける２色成形の境界は、延設部３２Ａの内延設部３２ｂにおける第１面部３２ｂ１の途中（例えば突出部２２の垂直板部１１ｃに対向する部分又は第１面部３２ｂ１の先端部分）としてもよい。また、図１１Ｄ及び図１１Ｅに示すように、カバー部材３０Ａにおける２色成形の境界は、延設部３２Ａにおける外延設部３２ａと内延設部３２ｂとの接続部であってもよい。この場合、図１１Ｄに示すように、取付部３３を透光性のままとして取付部３３を延設部３２Ａの外延設部３２ａと一体にしてもよいし、図１１Ｅに示すように、取付部３３を白色又は乳白として取付部３３を延設部３２Ａの内延設部３２ｂと一体にしてもよい。また、図１１Ｆに示すように、カバー部材３０Ａにおける２色成形の境界は、主部３１と延設部３２Ａとの接続部であってもよい。この場合、取付部３３とともに延設部３２Ａの外延設部３２ａ及び内延設部３２ｂの全体を白色又は乳白にするとよい。 Further, in FIG. 11A, the boundary of the two-color molding in the cover member 30A is the connection portion between the first surface portion 32b1 and the second surface portion 32b2 in the inner extension portion 32b of the extension portion 32A, but it is not limited thereto. For example, as shown in FIGS. 11B and 11C, the boundary of the two-color molding in the cover member 30A is in the middle of the first surface portion 32b1 of the inner extending portion 32b of the extending portion 32A (for example, the vertical plate portion 11c of the protruding portion 22). or the tip portion of the first surface portion 32b1). Further, as shown in FIGS. 11D and 11E, the boundary between the two-color molding in the cover member 30A may be a connection portion between the outer extending portion 32a and the inner extending portion 32b in the extending portion 32A. In this case, as shown in FIG. 11D, the mounting portion 33 may be integrated with the outer extension portion 32a of the extension portion 32A while leaving the mounting portion 33 translucent, or as shown in FIG. 33 may be white or milky white, and the mounting portion 33 may be integrated with the inner extending portion 32b of the extending portion 32A. Further, as shown in FIG. 11F, the boundary between the two-color molding in the cover member 30A may be a connecting portion between the main portion 31 and the extending portion 32A. In this case, it is preferable that the entire outer extending portion 32a and inner extending portion 32b of the extending portion 32A, together with the attachment portion 33, be white or milky white.
　なお、図１１Ａ～図１１Ｆにおいて、２色成形により異なる樹脂材料を層状に形成してもよい。例えば、カバー部材３０Ａにおける延設部３２Ａを天井側の第１層と床側の第２層との積層構造とし、第１層と第２層とを２色成形により形成してもよい。つまり、延設部３２Ａを２色２層とし、押出成型（２層押出）によってカバー部材３０Ａを形成してもよい。 Note that in FIGS. 11A to 11F, different resin materials may be formed into layers by two-color molding. For example, the extending portion 32A of the cover member 30A may have a laminated structure of a first layer on the ceiling side and a second layer on the floor side, and the first layer and the second layer may be formed by two-color molding. In other words, the cover member 30A may be formed by extrusion molding (two-layer extrusion) by forming the extending portion 32A in two layers with two colors.
　（変形例２）
　図１２Ａは、変形例２に係るＬＥＤ照明装置３Ｂの断面図である。 (Modification 2)
FIG. 12A is a cross-sectional view of an LED lighting device 3B according to Modification 2. FIG.
　上記実施の形態におけるＬＥＤ照明装置３では、カバー部材３０の延設部３２の先端は基板１１に当接していたが、図１２Ａに示すように、本変形例におけるＬＥＤ照明装置３Ｂでは、カバー部材３０Ｂの延設部３２Ｂの先端は、フレーム２０に当接している。具体的には、延設部３２Ｂの先端は、フレーム２０の主板部２１に当接している。 In the LED lighting device 3 in the above embodiment, the tip of the extending portion 32 of the cover member 30 was in contact with the substrate 11, but as shown in FIG. 12A, in the LED lighting device 3B in this modification, the cover member The distal end of the extending portion 32B of 30B is in contact with the frame 20. Specifically, the tip of the extending portion 32B is in contact with the main plate portion 21 of the frame 20.
　この構成により、ＬＥＤ照明装置３Ｂとしての強度を向上させることができるとともに、カバー部材３０Ｂの内部に虫が侵入することを抑制することができる。 With this configuration, it is possible to improve the strength of the LED lighting device 3B, and it is also possible to suppress insects from entering the inside of the cover member 30B.
　また、図１２Ａでは、カバー部材３０Ｂにおける延設部３２Ｂの内延設部３２ｂの根元部分は、外延設部３２ａと取付部３３との連結部分に接続されていたが、これに限らない。 Further, in FIG. 12A, the root portion of the inner extending portion 32b of the extending portion 32B in the cover member 30B is connected to the connection portion between the outer extending portion 32a and the attachment portion 33, but the present invention is not limited to this.
　例えば、図１２Ｂに示すように、カバー部材３０Ｂにおける延設部３２Ｂの内延設部３２ｂの根元部分は、取付部３３の端部ではなく、取付部３３の端部以外の一部に接続されていてもよい。つまり、延設部３２Ｂの内延設部３２ｂは、取付部３３の途中から延びていてもよい。 For example, as shown in FIG. 12B, the root portion of the inner extending portion 32b of the extending portion 32B in the cover member 30B is not connected to the end of the attaching portion 33 but to a part of the attaching portion 33 other than the end. You can leave it there. That is, the inner extending portion 32b of the extending portion 32B may extend from the middle of the attachment portion 33.
　また、図１２Ｃに示すように、カバー部材３０Ｂにおける延設部３２Ｂの内延設部３２ｂの根元部分は、外延設部３２ａの端部ではなく、外延設部３２ａの端部以外の一部に接続されていてもよい。つまり、延設部３２Ｂの内延設部３２ｂは、外延設部３２ａの途中から延びていてもよい。 Further, as shown in FIG. 12C, the root portion of the inner extending portion 32b of the extending portion 32B in the cover member 30B is not at the end of the outer extending portion 32a but at a part other than the end of the outer extending portion 32a. May be connected. That is, the inner extending portion 32b of the extending portion 32B may extend from the middle of the outer extending portion 32a.
　また、図１２Ｄに示すように、カバー部材３０Ｂにおける延設部３２Ｂの内延設部３２ｂの根元部分は、外延設部３２ａでもなく取付部３３でもなく、主部３１に接続されていてもよい。つまり、延設部３２Ｂの内延設部３２ｂは、主部３１の内面から延びていてもよい。この場合、図１２Ｄに示すように、延設部３２Ｂは、外延設部３２ａを有することなく内延設部３２ｂのみで構成されていてもよい。 Further, as shown in FIG. 12D, the root portion of the inner extending portion 32b of the extending portion 32B in the cover member 30B may be connected to the main portion 31 instead of the outer extending portion 32a or the attachment portion 33. . That is, the inner extending portion 32b of the extending portion 32B may extend from the inner surface of the main portion 31. In this case, as shown in FIG. 12D, the extending portion 32B may include only an inwardly extending portion 32b without having an outwardly extending portion 32a.
　なお、図１２Ａ～図１２Ｃは、上記実施の形態及び他の変形例に適用してもよい。 Note that FIGS. 12A to 12C may be applied to the above embodiment and other modifications.
　（変形例３）
　図１３は、変形例３に係るＬＥＤ照明装置３Ｃの断面図である。 (Modification 3)
FIG. 13 is a cross-sectional view of an LED lighting device 3C according to modification 3.
　上記実施の形態におけるＬＥＤ照明装置３では、フレーム２０の突出部２２の第２板部２２ｂは傾斜していたが、図１３に示すように、本変形例に係るＬＥＤ照明装置３Ｃでは、フレーム２０Ｃの突出部２２Ｃの第２板部２２ｂは、第１板部２２ａと同様に主板部２１と平行に形成されている。ただし、突出部２２Ｃにおいて、第１板部２２ａと第２板部２２ｂとは、異なる高さ位置に存在しており、突出部２２Ｃは、段差状に形成されている。なお、突出部２２Ｃの第２板部２２ｂは、主板部２１よりも床側に位置している。また、図１３に示すように、フレーム２０Ｃの側板部２３Ｃの先端部分には折曲部が設けられていなくてもよい。 In the LED lighting device 3 in the above embodiment, the second plate portion 22b of the protruding portion 22 of the frame 20 is inclined, but as shown in FIG. 13, in the LED lighting device 3C according to this modification, the frame 20C The second plate portion 22b of the protruding portion 22C is formed parallel to the main plate portion 21 similarly to the first plate portion 22a. However, in the protruding portion 22C, the first plate portion 22a and the second plate portion 22b are located at different height positions, and the protruding portion 22C is formed in a stepped shape. Note that the second plate portion 22b of the protruding portion 22C is located closer to the floor than the main plate portion 21. Further, as shown in FIG. 13, the bending portion may not be provided at the tip of the side plate portion 23C of the frame 20C.
　また、上記実施の形態におけるＬＥＤ照明装置３では、カバー部材３０の延設部３２の先端は基板１１に当接していたが、図１３に示すように、本変形例におけるＬＥＤ照明装置３Ｃでは、カバー部材３０Ｃの延設部３２Ｃの先端は、基板１１に当接しておらず、延設部３２Ｃの先端と基板１１との間に隙間が存在している。つまり、延設部３２Ｃは、先端が基板１１と離間するように形成されている。 Further, in the LED lighting device 3 in the above embodiment, the tip of the extending portion 32 of the cover member 30 was in contact with the substrate 11, but as shown in FIG. 13, in the LED lighting device 3C in this modification, The tip of the extending portion 32C of the cover member 30C does not contact the substrate 11, and a gap exists between the tip of the extending portion 32C and the substrate 11. In other words, the extending portion 32C is formed such that its tip is spaced apart from the substrate 11.
　この構成により、基板１１が接着剤等でフレーム２０Ｃに固定されている場合に、仮に接着剤が剥がれたとしても、基板１１が延設部３２Ｃで支持されるので、基板１１が落下することを防止できる。また、延設部３２Ｃに反射機能を持たせたときに、光取り出し効率をさらに改善させることができる。また、延設部３２Ｃと基板１１とを離間させることで、延設部３２Ｃと基板１１とが接触することで生じる異音を無くすことができる。 With this configuration, when the board 11 is fixed to the frame 20C with adhesive or the like, even if the adhesive comes off, the board 11 is supported by the extension part 32C, so the board 11 is prevented from falling. It can be prevented. Further, when the extension portion 32C is provided with a reflective function, the light extraction efficiency can be further improved. Further, by separating the extended portion 32C and the substrate 11, it is possible to eliminate abnormal noise caused by contact between the extended portion 32C and the substrate 11.
　（変形例４）
　図１４は、変形例４に係るＬＥＤ照明装置３Ｄの断面図である。 (Modification 4)
FIG. 14 is a cross-sectional view of an LED lighting device 3D according to modification example 4.
　上記実施の形態におけるＬＥＤ照明装置３では、カバー部材３０の延設部３２の先端は基板１１に当接していたが、図１４に示すように、本変形例におけるＬＥＤ照明装置３Ｄでは、カバー部材３０Ｄの延設部３２Ｄの先端は、フレーム２０Ｄに当接している。具体的には、延設部３２Ｄの先端は、フレーム２０Ｄの主板部２１に当接している。また、本変形例におけるカバー部材３０Ｄでは、取付部３３Ｄに延在部３３ｂが設けられている。延在部３３ｂは、フレーム２０Ｄの側板部２３の端部近傍から天井側に延在している。 In the LED lighting device 3 in the above embodiment, the tip of the extending portion 32 of the cover member 30 was in contact with the substrate 11, but as shown in FIG. 14, in the LED lighting device 3D in this modification, the cover member The distal end of the extending portion 32D of 30D is in contact with the frame 20D. Specifically, the tip of the extending portion 32D is in contact with the main plate portion 21 of the frame 20D. Further, in the cover member 30D in this modification, the attachment portion 33D is provided with an extension portion 33b. The extending portion 33b extends toward the ceiling from near the end of the side plate portion 23 of the frame 20D.
　この構成により、カバー部材３０Ｄの強度を向上させることができるので、ＬＥＤ照明装置３Ｄの強度をさらに向上させることができる。 With this configuration, the strength of the cover member 30D can be improved, so the strength of the LED lighting device 3D can be further improved.
　なお、上記実施の形態におけるＬＥＤ照明装置３では、フレーム２０の突出部２２は、平行板部である第１板部２２ａと傾斜板部である第２板部２２ｂとを有していたが、これに限らない。図１４に示されるＬＥＤ照明装置３Ｄのように、フレーム２０Ｄの突出部２２Ｄは、平行板部及び傾斜板部のうち傾斜板部のみを有していてもよい。 Note that in the LED lighting device 3 in the above embodiment, the protruding portion 22 of the frame 20 had the first plate portion 22a, which is a parallel plate portion, and the second plate portion 22b, which is an inclined plate portion. It is not limited to this. Like the LED lighting device 3D shown in FIG. 14, the protruding portion 22D of the frame 20D may have only the inclined plate portion out of the parallel plate portion and the inclined plate portion.
　（変形例５）
　図１５Ａ及び図１５Ｂは、変形例５に係るＬＥＤ照明装置３Ｅの断面図である。図１５Ａは、電源装置４が存在しない部分を切断したときの断面を示しており、図１５Ｂは、電源装置４が存在する部分を切断したときの断面を示している。 (Modification 5)
15A and 15B are cross-sectional views of an LED lighting device 3E according to modification 5. FIG. 15A shows a cross section taken through a portion where the power supply device 4 is not present, and FIG. 15B is a cross section taken through a portion where the power supply device 4 is present.
　図１５Ａ及び図１５Ｂに示すように、本変形例に係るＬＥＤ照明装置３Ｅは、上記実施の形態に係るＬＥＤ照明装置３において、カバー部材３０Ｅの延設部３２に凸部３４及び突起３５が形成された構成になっている。 As shown in FIGS. 15A and 15B, an LED lighting device 3E according to this modification is the same as the LED lighting device 3 according to the above embodiment, in which a convex portion 34 and a protrusion 35 are formed on the extending portion 32 of the cover member 30E. The configuration is as follows.
　凸部３４は、延設部３２からフレーム２０側に向かって突出しており、フレーム２０の動きを規制する規制部として機能する。本変形例において、凸部３４は、フレーム２０の突出部２２の第３板部２２ｃの側面に当接しうる位置に形成されている。一例として、凸部３４は、平板状であって、カバー部材３０Ｅの長手方向に延在するよう形成されている。また、本変形例において、凸部３４は、第３板部２２ｃと平行に形成されている。 The convex portion 34 protrudes from the extension portion 32 toward the frame 20 and functions as a restriction portion that restricts movement of the frame 20. In this modification, the convex portion 34 is formed at a position where it can come into contact with the side surface of the third plate portion 22c of the protruding portion 22 of the frame 20. As an example, the convex portion 34 has a flat plate shape and is formed to extend in the longitudinal direction of the cover member 30E. Furthermore, in this modification, the convex portion 34 is formed parallel to the third plate portion 22c.
　このようにカバー部材３０Ｅに凸部３４を設けることで、カバー部材３０Ｅ又はフレーム２０が動こうとしたときに凸部３４が突出部２２に当接するのでカバー部材３０Ｅ又はフレーム２０が動くことを抑制することができる。例えば、ＬＥＤ照明装置３Ｅを器具本体２（不図示）に取り付けるときにカバー部材３０Ｅに応力がかかってカバー部材３０Ｅが押し広げられる場合があるが、凸部３４を設けておくことでカバー部材３０Ｅが広げられたときに凸部３４がフレーム２０の突出部２２に当たることになる。これにより、カバー部材３０Ｅとフレーム２０とがネジで固定されていなくても、カバー部材３０Ｅがフレーム２０から外れにくくすることができる。また、凸部３４を設けておくことで、ＬＥＤ照明装置３Ｅを組み立てるときにフレーム２０とカバー部材３０Ｅとの位置合わせをすることもできる。 By providing the protrusion 34 on the cover member 30E in this way, when the cover member 30E or the frame 20 tries to move, the protrusion 34 comes into contact with the protrusion 22, thereby suppressing the movement of the cover member 30E or the frame 20. can do. For example, when attaching the LED lighting device 3E to the appliance main body 2 (not shown), stress may be applied to the cover member 30E and the cover member 30E may be pushed out. When the frame 20 is expanded, the protrusion 34 will come into contact with the protrusion 22 of the frame 20. Thereby, even if the cover member 30E and the frame 20 are not fixed with screws, the cover member 30E can be made difficult to come off from the frame 20. Further, by providing the convex portion 34, the frame 20 and the cover member 30E can be aligned when assembling the LED lighting device 3E.
　なお、凸部３４と突出部２２とは、当接していてもよいし、当接していなくてもよい。つまり、凸部３４と突出部２２との間に隙間があってもよい。この場合、凸部３４と突出部２２との間の隙間は、フレーム２０の側板部２３とカバー部材３０Ｅの取付部３３との間の隙間よりも小さい方がよい。これにより、カバー部材３０Ｅがフレーム２０からさらに外れにくくすることができる。 Note that the protrusion 34 and the protrusion 22 may or may not be in contact with each other. That is, there may be a gap between the convex portion 34 and the protruding portion 22. In this case, the gap between the convex portion 34 and the protruding portion 22 is preferably smaller than the gap between the side plate portion 23 of the frame 20 and the attachment portion 33 of the cover member 30E. Thereby, the cover member 30E can be made more difficult to come off from the frame 20.
　突起３５は、延設部３２におけるフレーム２０に当接しうる位置に形成されている。具体的には、突起３５は、延設部３２の内延設部３２ｂの面部に形成されている。また、突起３５は、フレーム２０の突出部２２の第１板部２２ａの表面に当接しうる位置に形成されている。一例として、突起３５は、カバー部材３０Ｅの長手方向に延在するように突条に形成されている。 The protrusion 35 is formed at a position in the extension portion 32 where it can come into contact with the frame 20. Specifically, the protrusion 35 is formed on the surface of the inner extending portion 32b of the extending portion 32. Further, the protrusion 35 is formed at a position where it can come into contact with the surface of the first plate portion 22a of the protrusion portion 22 of the frame 20. As an example, the protrusion 35 is formed into a protrusion so as to extend in the longitudinal direction of the cover member 30E.
　このように突起３５を設けることで、振動等によってフレーム２０とカバー部材３０Ｅとが接離を繰り返して生じる異音を低減することができる。なお、本変形例では、突起３５の頂部が突出部２２の第１板部２２ａの表面に当接している。また、異音を低減するための突起３５は、延設部３２ではなく、フレーム２０の突出部２２の第１板部２２ａに形成されていてもよい。突起３５は、フレーム２０及びカバー部材３０Ｅの一方又は両方に形成されていればよい。 By providing the protrusion 35 in this way, it is possible to reduce abnormal noise caused by repeated contact and separation between the frame 20 and the cover member 30E due to vibrations or the like. Note that in this modification, the top of the protrusion 35 is in contact with the surface of the first plate portion 22a of the protrusion 22. Further, the protrusion 35 for reducing abnormal noise may be formed on the first plate portion 22a of the protruding portion 22 of the frame 20 instead of on the extending portion 32. The protrusion 35 may be formed on one or both of the frame 20 and the cover member 30E.
　また、本変形例におけるＬＥＤ照明装置３Ｅでは、カバー部材３０Ｅは、さらに突起３６を有する。突起３６は、延設部３２の外延設部３２ａの天井側の面に形成されている。これにより、ＬＥＤ照明装置３Ｅを器具本体２（不図示）の凹部２ａに収納したときに、突起３６と凹部２ａの開口端縁２ａ１が当接するので、振動等によってカバー部材３０Ｅと器具本体２との間に生じる異音を低減することができる。 Furthermore, in the LED lighting device 3E in this modification, the cover member 30E further includes a protrusion 36. The protrusion 36 is formed on the ceiling-side surface of the externally extending portion 32 a of the extending portion 32 . As a result, when the LED lighting device 3E is housed in the recess 2a of the appliance main body 2 (not shown), the protrusion 36 and the opening edge 2a1 of the recess 2a come into contact with each other, so that the cover member 30E and the appliance main body 2 are brought into contact with each other due to vibration or the like. It is possible to reduce the abnormal noise that occurs during the process.
　なお、異音を低減させるための突起３５及び３６は、カバー部材３０Ｅの上記以外の場所に形成されていてもよい。例えば、カバー部材３０Ｅにおけるフレーム２０の側板部２３との接触部分（取付部３３等）又はカバー部材３０Ｅにおける器具本体２の凹部２ａの内壁面との接触部分（取付部３３等）に形成されていてもよい。また、突起３５及び３６は、カバー部材３０Ｅの長手方向の全長にわたって形成されていなくてもよい。例えば、突起３５及び３６は、カバー部材３０Ｅの長手方向に沿って断続的に複数形成されていてもよい。突起３５及び３６と、突起３５及び３６が当接しうる当たり面とは、面接触でもよいし、線接触でもよいし、点接触でもよい。この場合、異音を低減できる効果は、点接触の場合が最も高く、次に線接触の場合であり、その次は面接触の場合である。 Note that the protrusions 35 and 36 for reducing abnormal noise may be formed at locations other than the above on the cover member 30E. For example, it is formed in the contact portion of the cover member 30E with the side plate portion 23 of the frame 20 (attachment portion 33, etc.) or the contact portion (attachment portion 33, etc.) of the cover member 30E with the inner wall surface of the recess 2a of the instrument body 2. It's okay. Moreover, the protrusions 35 and 36 do not need to be formed over the entire length of the cover member 30E in the longitudinal direction. For example, a plurality of protrusions 35 and 36 may be formed intermittently along the longitudinal direction of the cover member 30E. The protrusions 35 and 36 and the contact surfaces with which the protrusions 35 and 36 can come into contact may be surface contact, line contact, or point contact. In this case, the effect of reducing noise is highest in the case of point contact, followed by line contact, and the next best is in case of surface contact.
　また、図１５Ａに示すように、本変形例に係るＬＥＤ照明装置３Ｅは、さらに、金具６０を備える。金具６０は、フレーム２０の天井側に配置されている。金具６０は、カバー部材３０Ｅの取付部３３を覆う凹部を有している。この構成により、カバー部材３０Ｅが外れることを防止することができる。金具６０は、例えば、カシメによってカバー部材３０Ｅの取付部３３等に取り付けられてもよいし、ネジによってフレーム２０等に取り付けられてもよい。 Furthermore, as shown in FIG. 15A, the LED lighting device 3E according to this modification further includes a metal fitting 60. The metal fitting 60 is arranged on the ceiling side of the frame 20. The metal fitting 60 has a recessed portion that covers the mounting portion 33 of the cover member 30E. With this configuration, it is possible to prevent the cover member 30E from coming off. For example, the metal fitting 60 may be attached to the attachment portion 33 of the cover member 30E by caulking, or may be attached to the frame 20 or the like with screws.
　なお、図１５Ａにおけるカバー部材３０Ｅの凸部３４は、突出部２２の第３板部２２ｃと平行に形成されていたが、これに限らない。 Note that although the convex portion 34 of the cover member 30E in FIG. 15A is formed parallel to the third plate portion 22c of the protruding portion 22, the present invention is not limited thereto.
　例えば、図１６に示されるＬＥＤ照明装置３Ｆのように、カバー部材３０Ｆの凸部３４Ｆは、突出部２２の第３板部２２ｃに対して傾斜するように形成されていてもよい。図１６では、凸部３４Ｆが基板１１側に向かって傾倒するように形成されている。これにより、図１５Ａの場合と比べて、カバー部材３０Ｆとフレーム２０とを容易に嵌め合わせることができる。 For example, like the LED lighting device 3F shown in FIG. 16, the convex portion 34F of the cover member 30F may be formed to be inclined with respect to the third plate portion 22c of the protruding portion 22. In FIG. 16, the convex portion 34F is formed so as to be inclined toward the substrate 11 side. Thereby, the cover member 30F and the frame 20 can be fitted together more easily than in the case of FIG. 15A.
　この場合、図１７に示されるＬＥＤ照明装置３Ｇのように、カバー部材３０Ｇの凸部３４Ｇを垂直部と傾斜部とを有するように形成してもよい。これにより、カバー部材３０Ｇとフレーム２０とを容易に嵌め合わせることができるとともに、カバー部材３０Ｇがフレーム２０から外れにくくすることができる。 In this case, like the LED lighting device 3G shown in FIG. 17, the convex portion 34G of the cover member 30G may be formed to have a vertical portion and an inclined portion. Thereby, the cover member 30G and the frame 20 can be easily fitted together, and the cover member 30G can be made difficult to come off from the frame 20.
　また、図１８に示されるＬＥＤ照明装置３Ｈのように、カバー部材３０Ｈの凸部３４Ｈは、フレーム２０Ｃの突出部２２Ｃの第３板部２２ｃに向かって傾倒するように形成されていてもよい。これにより、カバー部材３０Ｈがフレーム２０Ｃからさらに外れにくくすることができる。 Furthermore, like the LED lighting device 3H shown in FIG. 18, the convex portion 34H of the cover member 30H may be formed to be inclined toward the third plate portion 22c of the protrusion 22C of the frame 20C. Thereby, the cover member 30H can be made more difficult to come off from the frame 20C.
　この場合、図１９に示されるＬＥＤ照明装置３Ｉのように、カバー部材３０Ｉの凸部３４Ｉは、フレーム２０Ｃの突出部２２Ｃの第３板部２２ｃに向かって傾倒するとともに、２つの傾斜部を有するように屈曲するように形成されていてもよい。これにより、カバー部材３０Ｉがフレーム２０Ｃから外れにくくすることができるとともに、カバー部材３０Ｉとフレーム２０Ｃとを容易に嵌め合わせることができる。 In this case, like the LED lighting device 3I shown in FIG. 19, the convex portion 34I of the cover member 30I is inclined toward the third plate portion 22c of the protruding portion 22C of the frame 20C, and has two inclined portions. It may be formed to be bent as shown in FIG. Thereby, the cover member 30I can be prevented from coming off from the frame 20C, and the cover member 30I and the frame 20C can be easily fitted together.
　また、図２０に示されるＬＥＤ照明装置３Ｊのように、カバー部材３０Ｊの凸部３４Ｊは、垂直部と傾斜部とを有するように形成されていてもよい。具体的には、凸部３４Ｊは、突出部２２Ｃの第３板部２２ｃに向かって折り返すように屈曲するように形成されている。これにより、カバー部材３０Ｊがフレーム２０Ｃから外れにくくすることができるとともに、カバー部材３０Ｊとフレーム２０Ｃとを容易に嵌め合わせることができる。 Further, like the LED lighting device 3J shown in FIG. 20, the convex portion 34J of the cover member 30J may be formed to have a vertical portion and an inclined portion. Specifically, the convex portion 34J is formed so as to be bent back toward the third plate portion 22c of the protrusion portion 22C. Thereby, the cover member 30J can be prevented from coming off from the frame 20C, and the cover member 30J and the frame 20C can be easily fitted together.
　（変形例６）
　図２１Ａは、変形例６に係るＬＥＤ照明装置３Ｋの断面図である。 (Modification 6)
FIG. 21A is a cross-sectional view of an LED lighting device 3K according to modification 6.
　上記実施の形態におけるＬＥＤ照明装置３では、カバー部材３０の延設部３２は、フレーム２０の突出部２２を超えて基板１１及びフレーム２０の主板部２１と重なる位置まで延在していたが、これに限らない。 In the LED lighting device 3 in the embodiment described above, the extending portion 32 of the cover member 30 extends beyond the protruding portion 22 of the frame 20 to a position where it overlaps with the substrate 11 and the main plate portion 21 of the frame 20. It is not limited to this.
　例えば、図２１Ａに示されるＬＥＤ照明装置３Ｋのように、カバー部材３０Ｋの延設部３２Ｋは、フレーム２０の突出部２２の位置までしか延在しないように形成されていてもよい。 For example, as in the LED lighting device 3K shown in FIG. 21A, the extending portion 32K of the cover member 30K may be formed so as to extend only to the position of the protruding portion 22 of the frame 20.
　なお、図２１Ａでは、カバー部材３０Ｋの延設部３２Ｋの先端部の端面は、フレーム２０の主板部２１に接していなかったが、これに限らない。例えば、図２１Ｂに示すように、カバー部材３０Ｋの延設部３２Ｋの先端部の端面は、フレーム２０の主板部２１に接していてもよい。これにより、カバー部材３０Ｋが外れにくくなる。また、図１２Ａ～図１２Ｄの場合は、カバー部材３０Ｋにおける延設部３２Ｋと主部３１との二重カバー部分（万が一隙間からカバー部材３０Ｋの内部に虫が入って堆積しても虫が目立たない領域）とカバー部材３０Ｋにおける主部３１のみの一重カバー部分（万が一カバー部材３０Ｋの内部に虫が入って堆積すると虫が目立つ領域）とで境界があるので、その境界付近では取付構造等を取り付けることが難しかったが、図２１Ｂのようにすることで、図１２Ａ～図１２Ｄの場合と比べてフレーム２０の主板部２１における基板１１を配置できる部分（基板取付部）を広くすることができるので、電源装置４や金具等の取付構造等の取り付けを容易に行うことができる。 Note that in FIG. 21A, the end surface of the distal end of the extension portion 32K of the cover member 30K is not in contact with the main plate portion 21 of the frame 20, but the present invention is not limited to this. For example, as shown in FIG. 21B, the end surface of the distal end of the extending portion 32K of the cover member 30K may be in contact with the main plate portion 21 of the frame 20. This makes it difficult for the cover member 30K to come off. In addition, in the case of FIGS. 12A to 12D, the double cover part of the cover member 30K between the extension part 32K and the main part 31 (even if insects enter the inside of the cover member 30K through the gap and accumulate, the insects will not be noticeable). There is a boundary between the cover member 30K (an area where insects are not present) and the single cover part of only the main part 31 of the cover member 30K (an area where insects will be noticeable if insects get inside the cover member 30K and accumulate), so the mounting structure etc. should be removed near the boundary. Although it was difficult to attach it, by doing it as shown in FIG. 21B, the part (board mounting part) in the main plate part 21 of the frame 20 where the board 11 can be placed can be made wider than in the case of FIGS. 12A to 12D. Therefore, it is possible to easily attach the power supply device 4 and the attachment structure such as metal fittings.
　また、図１２Ｂでは、カバー部材３０Ｋの延設部３２Ｋの先端部の側面は、フレーム２０の突出部２２に接していたが、これに限らない。具体的には、図２１Ｃに示すように、カバー部材３０Ｋの延設部３２Ｋの先端部の側面は、フレーム２０の突出部２２に接していなくてもよい。つまり、カバー部材３０Ｋの延設部３２Ｋの先端部の側面と、フレーム２０の突出部２２との間に若干隙間（空間）が存在していてもよい。これにより、カバー部材３０Ｋをフレーム２０に嵌め込みやすくなる。 Furthermore, in FIG. 12B, the side surface of the tip end of the extending portion 32K of the cover member 30K is in contact with the protruding portion 22 of the frame 20, but the present invention is not limited thereto. Specifically, as shown in FIG. 21C, the side surface of the distal end portion of the extension portion 32K of the cover member 30K does not need to be in contact with the protrusion portion 22 of the frame 20. In other words, a slight gap (space) may exist between the side surface of the distal end of the extending portion 32K of the cover member 30K and the protruding portion 22 of the frame 20. This makes it easier to fit the cover member 30K into the frame 20.

　図２４は、変形例９に係るＬＥＤ照明装置３Ｎの断面図である。 (Modification 9)
FIG. 24 is a cross-sectional view of an LED lighting device 3N according to modification example 9.
　上記実施の形態におけるＬＥＤ照明装置３では、カバー部材３０の延設部３２は、フレーム２０の突出部２２の形状に一致するような形状で突出部２２に沿って形成されていたが、これに限らない。 In the LED lighting device 3 in the above embodiment, the extending portion 32 of the cover member 30 is formed along the protruding portion 22 in a shape that matches the shape of the protruding portion 22 of the frame 20. Not exclusively.
　例えば、図２４に示されるＬＥＤ照明装置３Ｎのように、カバー部材３０Ｎの延設部３２Ｎは、フレーム２０Ｃの突出部２２Ｃの形状に一致しない形状で突出部２２Ｃに沿って形成されていてもよい。つまり、カバー部材３０Ｎ及びフレーム２０Ｃには、延設部３２Ｎと突出部２２Ｃとが平行に形成されていない部分があってもよい。 For example, as in the LED lighting device 3N shown in FIG. 24, the extending portion 32N of the cover member 30N may be formed along the protruding portion 22C in a shape that does not match the shape of the protruding portion 22C of the frame 20C. . That is, there may be a portion of the cover member 30N and the frame 20C where the extending portion 32N and the protruding portion 22C are not formed in parallel.
　（変形例１０）
　図２５は、変形例１０に係るＬＥＤ照明装置３Ｏの断面図である。 (Modification 10)
FIG. 25 is a cross-sectional view of an LED lighting device 3O according to Modification 10.
　上記実施の形態におけるＬＥＤ照明装置３では、フレーム２０の突出部２２は、第２板部２２ｂが第１板部２２ａの外側に位置する形状であったが、図２５に示すように、本変形例におけるＬＥＤ照明装置３Ｏでは、フレーム２０Ｏの突出部２２Ｏは、第２板部２２ｂが第１板部２２ａの内側に位置する形状である。なお、本変形例における突出部２２Ｏは、垂直板部である第３板部２２ｃを有していない。 In the LED lighting device 3 in the above embodiment, the protruding portion 22 of the frame 20 has a shape in which the second plate portion 22b is located outside the first plate portion 22a, but as shown in FIG. In the LED lighting device 3O in the example, the protruding portion 22O of the frame 20O has a shape in which the second plate portion 22b is located inside the first plate portion 22a. Note that the protruding portion 22O in this modification does not have the third plate portion 22c, which is a vertical plate portion.
　また、本変形例におけるＬＥＤ照明装置３Ｏでは、上記変形例８のように、カバー部材３０Ｏの延設部３２Ｏは、主部３１の外側端部３１ａに接続されておらず、主部３１の外側端部３１ａから離れた位置からＬＥＤ１２に向かって延在している。また、本変形例における延設部３２Ｏは、上記変形例５のように、凸部３４及び突起３５を有する。 Furthermore, in the LED lighting device 3O in this modification, the extending portion 32O of the cover member 30O is not connected to the outer end 31a of the main portion 31, as in the above modification 8, and is not connected to the outer end 31a of the main portion 31. It extends toward the LED 12 from a position away from the end 31a. Further, the extension portion 32O in this modification includes a convex portion 34 and a protrusion 35 as in the fifth modification.
　なお、図２５では、凸部３４は、基板１１側に傾倒するように傾斜しているが、これに限らない。例えば、図２６に示されるＬＥＤ照明装置３Ｐのように、カバー部材３０Ｐの延設部３２Ｏに設けられた凸部３４Ｐは、突出部２２Ｏ側に傾倒するように傾斜していてもよい。 Note that in FIG. 25, the convex portion 34 is inclined so as to be inclined toward the substrate 11 side, but the present invention is not limited to this. For example, as in the LED lighting device 3P shown in FIG. 26, the convex portion 34P provided on the extending portion 32O of the cover member 30P may be inclined so as to be inclined toward the protruding portion 22O.
　（変形例１１）
　図２７は、変形例１１に係るＬＥＤ照明装置３Ｑの断面図である。 (Modification 11)
FIG. 27 is a sectional view of an LED lighting device 3Q according to Modification Example 11.
　上記実施の形態におけるＬＥＤ照明装置３では、フレーム２０の突出部２２における第１板部２２ａは、基板１１及び主板部２１に平行な平行板部であったが、これに限らない。 In the LED lighting device 3 in the above embodiment, the first plate portion 22a of the protruding portion 22 of the frame 20 is a parallel plate portion parallel to the substrate 11 and the main plate portion 21, but the present invention is not limited to this.
　例えば、図２７に示されるＬＥＤ照明装置３Ｑのように、フレーム２０Ｑの突出部２２Ｑにおける第１板部２２ａは、基板１１及び主板部２１に対して傾斜する傾斜板部であってもよい。具体的には、突出部２２Ｑは、第１板部２２ａと第２板部２２ｂとで屈曲するように形成されている。なお、本変形例の突出部２２Ｑには、垂直板部である第３板部２２ｃが形成されていない。 For example, like the LED lighting device 3Q shown in FIG. 27, the first plate portion 22a of the protruding portion 22Q of the frame 20Q may be an inclined plate portion that is inclined with respect to the substrate 11 and the main plate portion 21. Specifically, the protruding portion 22Q is formed to be bent between the first plate portion 22a and the second plate portion 22b. Note that the third plate portion 22c, which is a vertical plate portion, is not formed in the protruding portion 22Q of this modification.
　（変形例１２）
　図２８は、変形例１２に係るＬＥＤ照明装置３Ｒの断面図である。 (Modification 12)
FIG. 28 is a cross-sectional view of an LED lighting device 3R according to modification 12.
　上記実施の形態におけるＬＥＤ照明装置３では、フレーム２０の突出部２２は平板部のみで構成されていたが、これに限らない。 In the LED lighting device 3 in the above embodiment, the protruding portion 22 of the frame 20 is composed of only a flat plate portion, but the present invention is not limited to this.
　例えば、図２８に示されるＬＥＤ照明装置３Ｒのように、フレーム２０Ｒの突出部２２Ｒは、円弧状に湾曲する曲板部で構成されていてもよい。つまり、突出部２２Ｒを構成する板部は、平板に限らず、曲板であってもよい。 For example, as in the LED lighting device 3R shown in FIG. 28, the protruding portion 22R of the frame 20R may be composed of a curved plate portion curved in an arc shape. In other words, the plate portion constituting the protruding portion 22R is not limited to a flat plate, but may be a curved plate.
　また、図２８に示すように、カバー部材３０Ｒの延設部３２Ｒは、湾曲する突出部２２Ｒに沿った形状にしてもよい。具体的には、延設部３２Ｒは、突出部２２Ｒの湾曲形状に嵌合するような形状としてもよい。このように、延設部３２Ｒにおける突出部２２Ｒの板部に当接しうる面部の形状は、平面に限らず、湾曲面であってもよい。 Furthermore, as shown in FIG. 28, the extending portion 32R of the cover member 30R may have a shape that follows the curved protrusion 22R. Specifically, the extending portion 32R may have a shape that fits into the curved shape of the protruding portion 22R. In this way, the shape of the surface portion of the extending portion 32R that can come into contact with the plate portion of the protruding portion 22R is not limited to a flat surface, but may be a curved surface.
　（変形例１３）
　図２９は、変形例１３に係るＬＥＤ照明器具１Ｓ及びＬＥＤ照明装置３Ｓの断面図である。 (Modification 13)
FIG. 29 is a cross-sectional view of an LED lighting fixture 1S and an LED lighting device 3S according to modification 13.
　本変形例に係るＬＥＤ照明器具１Ｓでは、器具本体２の凹部２ａの内壁面に貫通孔２ｄが設けられている。 In the LED lighting fixture 1S according to this modification, a through hole 2d is provided in the inner wall surface of the recess 2a of the fixture body 2.
　また、本変形例に係るＬＥＤ照明装置３Ｓでは、フレーム２０Ｓの突出部２２に、貫通孔２４が設けられている。具体的には、貫通孔２４は、突出部２２におけるＬＥＤ１２側の側壁を構成する第３板部２２ｃに設けられている。なお、カバー部材３０Ｓの延設部３２Ｓは、フレーム２０Ｓの突出部２２の上面の位置までしか延在していない。つまり、延設部３２Ｓは、突出部２２の第３板部２２ｃを覆っていない。 Furthermore, in the LED lighting device 3S according to this modification, a through hole 24 is provided in the protrusion 22 of the frame 20S. Specifically, the through hole 24 is provided in the third plate portion 22c that constitutes the side wall of the protruding portion 22 on the LED 12 side. Note that the extending portion 32S of the cover member 30S extends only to the position of the upper surface of the protruding portion 22 of the frame 20S. That is, the extending portion 32S does not cover the third plate portion 22c of the protruding portion 22.
　この構成により、カバー部材３０Ｓとフレーム２０Ｓとで囲まれる空間領域と凹部２ａにおけるフレーム２０Ｓの天井側の空間領域Ｓとが貫通孔２４を介して連通する。また、貫通孔２ｄを介して凹部２ａの内部空間（空間領域Ｓ）と凹部２ａの外部空間とが連通する。これにより、貫通孔２４及び２ｄによってＬＥＤ１２で発生した熱を自然対流によって効果的に放熱させることができる。カバー部材３０Ｓとフレーム２０Ｓとで囲まれる空間領域に熱がこもることを抑制できる。 With this configuration, the spatial region surrounded by the cover member 30S and the frame 20S and the spatial region S on the ceiling side of the frame 20S in the recess 2a communicate with each other via the through hole 24. Further, the internal space (space area S) of the recess 2a and the external space of the recess 2a communicate with each other via the through hole 2d. Thereby, the heat generated by the LED 12 can be effectively radiated by natural convection through the through holes 24 and 2d. Heat can be prevented from accumulating in the spatial region surrounded by the cover member 30S and the frame 20S.
　（その他の変形例）
　以上、本発明に係るＬＥＤ照明器具及びＬＥＤ照明装置について、実施の形態及び変形例に基づいて説明したが、本発明は、これらの実施の形態及び変形例に限定されるものではない。 (Other variations)
Although the LED lighting fixture and LED lighting device according to the present invention have been described above based on the embodiments and modifications, the present invention is not limited to these embodiments and modifications.
　上記実施の形態及び変形例では、ＬＥＤ照明装置に用いられるフレームとしては種々の形状のものを例示したが、以下に説明する形状のフレームを用いてもよい。なお、以下に説明するフレームの中には、既に上述した形状を有するものも含まれる。また、以下に説明するフレームについては、形状は異なるものの、便宜上、上記実施の形態と同じ符号を用いている。また、以下に説明するフレームの特徴は、互いに適用しあってもよいし、上記実施の形態及び変形例に適用してもよい。 In the above embodiments and modified examples, various shapes of frames were exemplified as frames used in the LED lighting device, but frames having the shapes described below may also be used. Note that the frames described below include those having the shapes already described above. Further, for the frames described below, although the shapes are different, for convenience, the same symbols as in the above embodiment are used. Furthermore, the features of the frame described below may be applied to each other or to the above embodiments and modified examples.
　まず、側板部２３の長さについては、任意の長さのフレームを用いることができる。具体的には、図３０に示されるように、側板部２３の先端が主板部２１よりも天井側に位置するように形成されたフレーム２０１を用いてもよいし、図３１に示されるように、側板部２３の先端が主板部２１の位置となるように形成されたフレーム２０２を用いてもよいし、図３２に示されるように、側板部２３が形成されていないＩ型のフレーム２０３を用いてもよい。なお、側板部２３の長さが長ければ長いほど、フレームの強度を高くすることができる。 First, regarding the length of the side plate portion 23, a frame of any length can be used. Specifically, as shown in FIG. 30, a frame 201 formed such that the tip of the side plate part 23 is located closer to the ceiling than the main plate part 21 may be used, or as shown in FIG. , a frame 202 formed so that the tip of the side plate part 23 is located at the position of the main plate part 21 may be used, or an I-shaped frame 203 in which the side plate part 23 is not formed may be used as shown in FIG. May be used. Note that the longer the side plate portion 23 is, the higher the strength of the frame can be.
　また、フレーム２０の突出部２２の形状についても、任意の形状のフレームを用いることができる。 Also, regarding the shape of the protruding portion 22 of the frame 20, a frame of any shape can be used.
　例えば、図３３に示されるように、外側に向かって傾斜する傾斜板部が設けられた突出部２２を有するフレーム２０４を用いてもよいし、図３４に示されるように、内側に向かって傾斜する傾斜板部が設けられた突出部２２を有するフレーム２０５を用いてもよいし、図３５に示されるように、外側に向かって傾斜する傾斜板部と内側に向かって傾斜する傾斜板部とを有する断面Ｖ字状（三角状）の突出部２２を有するフレーム２０６を用いてもよいし、図３６に示すように、外側に向かって傾斜する傾斜板と内側に向かって傾斜する傾斜板部と垂直板部とが設けられた突出部２２を有するフレーム２０７を用いてもよい。 For example, as shown in FIG. 33, a frame 204 having a protruding portion 22 provided with an inclined plate portion that slopes outward may be used, or as shown in FIG. 34, a frame 204 that slopes inward. Alternatively, as shown in FIG. 35, a frame 205 having a protruding portion 22 provided with an inclined plate portion may be used, or as shown in FIG. A frame 206 having a protrusion 22 having a V-shaped (triangular) cross section may be used, or as shown in FIG. A frame 207 having a protruding portion 22 provided with a vertical plate portion and a vertical plate portion may also be used.
　また、図３７に示されるように、湾曲板部で構成された突出部２２を有するフレーム２０８を用いてもよいし、図３８に示されるように、内側に傾斜板部が設けられた突出部２２を有するフレーム２０９を用いてもよいし、図３９に示されるように、外側に傾斜板部が設けられた突出部２２を有するフレーム２１０を用いてもよいし、図４０に示すように、外側と内側との両方に傾斜板部が設けられた突出部２２を有するフレーム２１１を用いてもよい。 Further, as shown in FIG. 37, a frame 208 having a protrusion 22 formed of a curved plate may be used, or as shown in FIG. 22, or as shown in FIG. 39, a frame 210 having a protruding portion 22 provided with an inclined plate portion on the outside may be used, or as shown in FIG. A frame 211 having a protrusion 22 provided with inclined plate portions on both the outside and the inside may be used.
　また、図４１～図４３に示されるように、傾斜板部が設けられていない突出部２２を有するフレーム２１２、２１３、２１４を用いてもよい。図４１～図４３に示されるフレーム２１２、２１３、２１４の突出部２２は、いずれも、段差状に形成されている。なお、図４１に示されるフレーム２１２は、側板部２３の先端が主板部２１よりも天井側に位置するように形成されており、図４２に示されるフレーム２１３は、側板部２３の先端が主板部２１の位置となるように形成されており、図４３に示されるフレーム２１４は、側板部２３が形成されていない形状である。 Furthermore, as shown in FIGS. 41 to 43, frames 212, 213, and 214 having protruding portions 22 without an inclined plate portion may be used. The protrusions 22 of the frames 212, 213, and 214 shown in FIGS. 41 to 43 are all formed in a stepped shape. Note that the frame 212 shown in FIG. 41 is formed such that the tip of the side plate 23 is located closer to the ceiling than the main plate 21, and the frame 213 shown in FIG. The frame 214 shown in FIG. 43 has a shape in which the side plate portion 23 is not formed.
　この場合、段差状に形成された突出部２２を有するフレームとしては、図４４～図５０に示されるフレーム２１５～２２１を用いることができる。具体的には、図４４に示されるフレーム２１５の突出部２２は、主板部２１と同じ高さ位置の平行板部と、主板部２１とは異なる高さ位置の平行板部とを有する。図４５に示されるフレーム２１６の突出部２２は、いずれも主板部２１とは異なる高さ位置の２つの平行板部を有する。図４６に示されるフレーム２１７の突出部２２は、平行板部と、平行板部の内側に位置する傾斜板部とを有する。図４７に示されるフレーム２１８の突出部２２は、平行板部と、平行板部の外側に位置し且つ内側に傾斜する傾斜板部とを有する。図４８に示されるフレーム２１９の突出部２２は、外側に傾斜する傾斜板部と内側に傾斜する傾斜板部とを有する。図４９に示されるフレーム２２０の突出部２２は、平行板部と、平行板部の両側に位置する一対の傾斜板部とを有する。図５０に示されるフレーム２２１の突出部２２は、異なる高さ位置の２つの平行板部と、平行板部の内側に位置する傾斜板部とを有する。 In this case, frames 215 to 221 shown in FIGS. 44 to 50 can be used as the frame having the protrusion 22 formed in a stepped shape. Specifically, the protruding portion 22 of the frame 215 shown in FIG. 44 has a parallel plate portion at the same height as the main plate portion 21 and a parallel plate portion at a different height from the main plate portion 21. The protruding portion 22 of the frame 216 shown in FIG. 45 has two parallel plate portions each having a different height position from the main plate portion 21. As shown in FIG. The protruding portion 22 of the frame 217 shown in FIG. 46 has a parallel plate portion and an inclined plate portion located inside the parallel plate portion. The protruding portion 22 of the frame 218 shown in FIG. 47 has a parallel plate portion and an inclined plate portion located outside the parallel plate portion and inclined inward. The protruding portion 22 of the frame 219 shown in FIG. 48 has an inclined plate portion that slopes outward and an inclined plate portion that slopes inward. The protruding portion 22 of the frame 220 shown in FIG. 49 has a parallel plate portion and a pair of inclined plate portions located on both sides of the parallel plate portion. The protruding portion 22 of the frame 221 shown in FIG. 50 has two parallel plate portions at different height positions and an inclined plate portion located inside the parallel plate portion.
　なお、図５１に示されるフレーム２２２のように、主板部２１における突出部２２との境界部分に補強リブ２１ｂを形成してもよいし、図５２に示されるフレーム２２３のように、突出部２２が形成されていない場合でも、主板部２１の両面に補強リブ（補強ビード）２１ｃ及び２１ｄを形成してもよい。これにより、側板部２３が短かかったり側板部２３が形成されていなかったりあるいは突出部２２が形成されていないような高さが低いフレームであっても、フレームの強度を確保することができる。補強リブ２１ｂ、２１ｃ、２１ｄは、プレス加工により形成することができる。 Note that, as in a frame 222 shown in FIG. 51, a reinforcing rib 21b may be formed at the boundary between the main plate 21 and the protrusion 22, or as in a frame 223 shown in FIG. Even if these are not formed, reinforcing ribs (reinforcing beads) 21c and 21d may be formed on both sides of the main plate portion 21. This makes it possible to ensure the strength of the frame even if the frame has a short side plate portion 23 or is not formed with the side plate portion 23 or has a low height such that the protrusion portion 22 is not formed. The reinforcing ribs 21b, 21c, and 21d can be formed by press working.
　また、上記実施の形態等において、外延設部３２ａを主部３１の一部としてもよい。この場合、延設部３２は、例えば内延設部３２ｂのみとなり、主部３１の一部である外延設部３２ａからカバー部材３０の内方に向かって延在することになる。 Furthermore, in the above embodiments and the like, the externally extending portion 32a may be a part of the main portion 31. In this case, the extending portion 32 is, for example, only the inner extending portion 32b, which extends inward from the outer extending portion 32a that is a part of the main portion 31.
　また、上記実施の形態等では、ＬＥＤ照明装置３を器具本体２に取り付ける場合、ＬＥＤ照明装置３を回転させることで、ＬＥＤ照明装置３を器具本体２に取り付けたが、これに限らない。つまり、ＬＥＤ照明装置３を回転させることなく、ＬＥＤ照明装置３を器具本体２に取り付けてもよい。具体的には、ＬＥＤ照明装置３に設けられた板バネ等を天井に設置された器具本体２に引っ掛けて、器具本体２に向かってＬＥＤ照明装置３を平行移動させるように鉛直方向に移動させることで、ＬＥＤ照明装置３を器具本体２に取り付けてもよい。この場合、ＬＥＤ照明装置３を器具本体２の凹部２ａに鉛直方向に押し込んで嵌め込むことで、ＬＥＤ照明装置３を器具本体２に取り付けることができる。 Furthermore, in the above embodiments and the like, when attaching the LED lighting device 3 to the fixture main body 2, the LED lighting device 3 is attached to the fixture main body 2 by rotating the LED lighting device 3, but the present invention is not limited to this. That is, the LED lighting device 3 may be attached to the appliance main body 2 without rotating the LED lighting device 3. Specifically, a plate spring or the like provided on the LED lighting device 3 is hooked onto the fixture main body 2 installed on the ceiling, and the LED lighting device 3 is moved in the vertical direction so as to be translated in parallel toward the fixture main body 2. In this way, the LED lighting device 3 may be attached to the appliance main body 2. In this case, the LED lighting device 3 can be attached to the fixture main body 2 by pushing the LED lighting device 3 vertically into the recess 2a of the fixture main body 2 and fitting it.
　また、上記実施の形態等では、ＬＥＤ１２としてＬＥＤチップがパッケージに実装されたＳＭＤタイプのＬＥＤ素子を用いており、基板１１とＬＥＤ１２とからなる発光モジュールがＳＭＤタイプのＬＥＤモジュールであったが、これに限らない。例えば、基板１１とＬＥＤ１２とからなる発光モジュールは、ＣＯＢ（Ｃｈｉｐ　Ｏｎ　Ｂｏａｒｄ）タイプのＬＥＤモジュールであってもよい。この場合、ＬＥＤ１２として、ＬＥＤチップ（ベアチップ）そのものを用いて、基板１１に複数のＬＥＤ１２（ＬＥＤチップ）を直線状に配列し、封止部材（例えば蛍光体含有樹脂）によって複数のＬＥＤ１２を一括又は個別に封止すればよい。 Further, in the above embodiments, an SMD type LED element in which an LED chip is mounted in a package is used as the LED 12, and the light emitting module consisting of the substrate 11 and the LED 12 is an SMD type LED module. Not limited to. For example, the light emitting module including the substrate 11 and the LED 12 may be a COB (Chip On Board) type LED module. In this case, LED chips (bare chips) themselves are used as the LEDs 12, and a plurality of LEDs 12 (LED chips) are arranged linearly on the substrate 11, and the plurality of LEDs 12 are sealed together or They can be sealed individually.
　また、上記実施の形態等では、拡散性及び透光性を有するカバー部材３０を用いたが、これに限らない。例えば、カバー部材３０に代えて、拡散性及び透光性のうち透光性のみを有する透光カバーを用いてもよい。この場合、透光カバーとして、向こう側が透けて見えるくらいに透過率が高い透明カバーを用いてもよい。 Further, in the above embodiments, the cover member 30 having diffusivity and translucency is used, but the present invention is not limited to this. For example, instead of the cover member 30, a light-transmitting cover having only light-transmitting property among diffusing property and light-transmitting property may be used. In this case, a transparent cover with high transmittance so that the other side can be seen through may be used as the light-transmitting cover.
　その他、上記実施の形態及び変形例に対して当業者が思い付く各種変形を施して得られる形態や、本発明の趣旨を逸脱しない範囲で実施の形態及び変形例における構成要素及び機能を任意に組み合わせることで実現される形態も本発明に含まれる。また、本願出願時の請求の範囲に記載された複数の請求項の各々における１つ又は複数の構成要素を任意に組み合わせたものも本発明に含まれる。また、本願出願時の請求の範囲に記載された引用形式請求項を、任意の複数の請求項を引用するようにマルチクレーム又はマルチマルチクレームとしたときに、そのマルチクレーム又はマルチマルチクレームに含まれる全ての請求項の組み合わせの発明も本発明に含まれる。 In addition, forms obtained by applying various modifications to the above embodiments and modifications that those skilled in the art can think of, and arbitrary combinations of components and functions in the embodiments and modifications without departing from the spirit of the present invention.
