特許文献１に開示されている照明器具では、放熱作用を有するヒートシンクが、ＬＥＤ基板を取り付けるための基板取付部材としても機能する。このとき、基板取付部材は、ＬＥＤ基板の裏面全体に接するものとされていることから、基板取付部材の全長は、ＬＥＤ基板の全長に合うように構成されている。そのため、基板取付部材の重量は、照明器具全体の重量のうち大きな比率を占めており、照明器具の軽量化への妨げとなっている。 In the lighting fixture disclosed in Patent Document 1, the heat sink having a heat dissipation function also functions as a board mounting member for mounting the LED board. At this time, since the board mounting member is in contact with the entire back surface of the LED board, the total length of the board mounting member is configured to match the total length of the LED board. Therefore, the weight of the board mounting member occupies a large proportion of the weight of the entire lighting fixture, which hinders the weight reduction of the lighting fixture.

本開示は、このような従来技術の有する課題に鑑みてなされたものである。そして、本開示の目的は、例えば、軽量化に有利な照明器具を提供することにある。 The present disclosure has been made in view of the problems of the prior art. An object of the present disclosure is, for example, to provide a lighting fixture which is advantageous for weight reduction.

Further, the X direction and the Y direction which are perpendicular to each other in the plane perpendicular to the Z direction are defined, and the longitudinal direction of the luminaire is defined as the X direction.

まず、本実施形態に係る照明器具の構成について説明する。図１は、本開示の一実施形態に係る照明器具１０の外観を示す斜視図である。照明器具１０は、屋内外を問わず使用可能で、光射出面が細長く、全体としても細長い形状の照明器具である。特に、照明器具１０は、食料品や飲料品を取り扱う店舗等で用いられる冷蔵・冷凍ショーケース等に採用可能である。 First, the configuration of the lighting fixture according to the present embodiment will be described. FIG. 1 is a perspective view showing the appearance of the lighting fixture 10 according to the embodiment of the present disclosure. The lighting fixture 10 can be used both indoors and outdoors, and is a lighting fixture having an elongated light emitting surface and an elongated shape as a whole. In particular, the lighting fixture 10 can be used in a refrigerated / frozen showcase or the like used in a store or the like that handles food or beverages.

照明器具１０は、外部から視認可能な構成として、ＬＥＤ基板等を内部に収容するカバー１８と、カバー１８の一端を覆う第１蓋部２０と、カバー１８の他端を覆う第２蓋部２２とを備える。 The lighting fixture 10 has a cover 18 that houses the LED substrate and the like inside, a first lid portion 20 that covers one end of the cover 18, and a second lid portion 22 that covers the other end of the cover 18, as a configuration that can be visually recognized from the outside. And prepare.

カバー１８は、直管形状を有し、樹脂等の透光性の材料から形成される。なお、カバー１８の具体的形状、特に断面形状については後述する。カバー１８は、内部のＬＥＤから発せられた光を外部に透過可能とし、光射出面として照明器具１０の外観を構成する。また、照明器具１０が冷蔵・冷凍ショーケースに設置される場合には、カバー１８は、ＬＥＤ基板等の構成要素を冷気から保護する。 The cover 18 has a straight tube shape and is formed of a translucent material such as resin. The specific shape of the cover 18, particularly the cross-sectional shape, will be described later. The cover 18 allows the light emitted from the internal LED to be transmitted to the outside, and constitutes the appearance of the luminaire 10 as a light emitting surface. Further, when the lighting fixture 10 is installed in a refrigerated / frozen showcase, the cover 18 protects components such as an LED substrate from cold air.

第１蓋部２０及び第２蓋部２２は、樹脂等の材料から形成され、カバー１８に対して取り付け及び取り外し自在である。一方の蓋部、例えば第１蓋部２０には、外部の電源に接続される電気配線２４が取り付けられる。電気配線２４の一端は、カバー１８又は第１蓋部２０の内部でＬＥＤ基板に接続される。 The first lid portion 20 and the second lid portion 22 are formed of a material such as resin, and can be attached to and detached from the cover 18. An electric wiring 24 connected to an external power source is attached to one of the lids, for example, the first lid 20. One end of the electrical wiring 24 is connected to the LED substrate inside the cover 18 or the first lid portion 20.

図２は、照明器具１０の内部構成を示す斜視図である。図２では、図１に示す照明器具１０の使用状態に代えて、第１蓋部２０からカバー１８を長手方向に引き抜いた照明器具１０の分解状態を示している。また、図３は、図２中に示されるＩＩＩ−ＩＩＩ断面に対応した、照明器具１０の断面図である。 FIG. 2 is a perspective view showing the internal configuration of the luminaire 10. FIG. 2 shows a disassembled state of the luminaire 10 in which the cover 18 is pulled out in the longitudinal direction from the first lid portion 20 instead of the use state of the luminaire 10 shown in FIG. Further, FIG. 3 is a cross-sectional view of the luminaire 10 corresponding to the cross section III-III shown in FIG.

照明器具１０は、内部構成として、ＬＥＤ基板と、基板取付部材１６とを備える。ここで、ＬＥＤ基板は、複数存在してもよい。そこで、照明器具１０には、少なくとも第１ＬＥＤ基板１４ａと第２ＬＥＤ基板１４ｂ（図４参照）との２つのＬＥＤ基板が含まれるものとする。なお、第１ＬＥＤ基板１４ａと第２ＬＥＤ基板１４ｂとは、それぞれ同一形状及び同一構成である。そこで、形状及び構成については、以下、第１ＬＥＤ基板１４ａを例に説明する。 The lighting fixture 10 includes an LED substrate and a substrate mounting member 16 as an internal configuration. Here, a plurality of LED substrates may exist. Therefore, it is assumed that the luminaire 10 includes at least two LED substrates, a first LED substrate 14a and a second LED substrate 14b (see FIG. 4). The first LED substrate 14a and the second LED substrate 14b have the same shape and the same configuration, respectively. Therefore, the shape and configuration will be described below by taking the first LED substrate 14a as an example.

第１ＬＥＤ基板１４ａは、長手方向に延伸する基板である。第１ＬＥＤ基板１４ａの表面１４０上には、光源としての複数のＬＥＤ１２が、長手方向に沿って所定の間隔を隔てて実装されている。なお、本実施形態では、光源の一例としてＬＥＤを採用するが、ＬＥＤ以外の発光素子を採用することも可能である。また、表面１４０上には、複数のＬＥＤ１２が長手方向に沿って一列に配列されているものとしているが、長手方向に沿って並列に配列されているものとしてもよい。 The first LED substrate 14a is a substrate extending in the longitudinal direction. A plurality of LEDs 12 as a light source are mounted on the surface 140 of the first LED substrate 14a at predetermined intervals along the longitudinal direction. In this embodiment, an LED is used as an example of the light source, but a light emitting element other than the LED can also be used. Further, although a plurality of LEDs 12 are arranged in a row along the longitudinal direction on the surface 140, they may be arranged in parallel along the longitudinal direction.

また、第１ＬＥＤ基板１４ａは、長手方向のそれぞれの端部１４２，１４３の近傍に、表面１４０と裏面１４８との間を貫通する貫通孔１４１を有する。貫通孔１４１は、例えば、ＬＥＤ１２の配列に合い、いずれかの隣り合うＬＥＤ１２同士の中間位置に形成されている。 Further, the first LED substrate 14a has a through hole 141 penetrating between the front surface 140 and the back surface 148 in the vicinity of the respective ends 142 and 143 in the longitudinal direction. The through hole 141 matches the arrangement of the LEDs 12, for example, and is formed at an intermediate position between any of the adjacent LEDs 12.

基板取付部材１６は、第１ＬＥＤ基板１４ａ及び第２ＬＥＤ基板１４ｂの双方又は一方を取付可能とし、カバー１８に接触保持される。本実施形態では、基板取付部材１６は、第１基板取付部材１６ａと、第２基板取付部材１６ｂとの２種類が存在する。 The board mounting member 16 allows both or one of the first LED board 14a and the second LED board 14b to be mounted, and is contact-held to the cover 18. In the present embodiment, the board mounting member 16 has two types, a first board mounting member 16a and a second board mounting member 16b.

図４は、第１基板取付部材１６ａ及び第２基板取付部材１６ｂに、第１ＬＥＤ基板１４ａ又は第２ＬＥＤ基板１４ｂを取り付けた状態を示す斜視図である。 FIG. 4 is a perspective view showing a state in which the first LED board 14a or the second LED board 14b is attached to the first board mounting member 16a and the second board mounting member 16b.

第１基板取付部材１６ａは、第１ＬＥＤ基板１４ａ及び第２ＬＥＤ基板１４ｂのそれぞれを取付可能とする。つまり、第１基板取付部材１６ａは、第１ＬＥＤ基板１４ａの端部１４３と、第２ＬＥＤ基板１４ｂの端部１４４とを近接させた状態でそれぞれ取り付けることで、第１ＬＥＤ基板１４ａと第２ＬＥＤ基板１４ｂとを直列に連結させるための基板連結部材とも言える。すなわち、照明器具１０では、複数の第１基板取付部材１６ａを用いれば、第１ＬＥＤ基板１４ａ及び第２ＬＥＤ基板１４ｂのみならず、３つ以上のＬＥＤ基板を直列に連結させることができる。 The first board mounting member 16a can mount each of the first LED board 14a and the second LED board 14b. That is, the first board mounting member 16a can be attached to the first LED board 14a and the second LED board 14b by mounting the end portion 143 of the first LED board 14a and the end portion 144 of the second LED board 14b in close proximity to each other. It can be said that it is a board connecting member for connecting the above in series. That is, in the lighting fixture 10, if a plurality of first board mounting members 16a are used, not only the first LED board 14a and the second LED board 14b but also three or more LED boards can be connected in series.

第２基板取付部材１６ｂは、第１蓋部２０又は第２蓋部２２のいずれかに最も接近するＬＥＤ基板を取付可能とする。ここで、図２及び図４を参照すると、第１蓋部２０に最も接近するＬＥＤ基板は、第１ＬＥＤ基板１４ａである。このとき、第２基板取付部材１６ｂは、第１ＬＥＤ基板１４ａにおける第１蓋部２０側の端部１４２の近傍を取り付ける。すなわち、照明器具１０には、第１蓋部２０に近接しているＬＥＤ基板の端部の取り付けと、第２蓋部２２に近接しているＬＥＤ基板の端部の取り付けとのそれぞれを役割とする２つの第２基板取付部材１６ｂが存在することになる。 The second board mounting member 16b allows the LED board that is closest to either the first lid portion 20 or the second lid portion 22 to be mounted. Here, referring to FIGS. 2 and 4, the LED substrate closest to the first lid portion 20 is the first LED substrate 14a. At this time, the second substrate mounting member 16b attaches the vicinity of the end portion 142 on the first lid portion 20 side of the first LED substrate 14a. That is, the lighting fixture 10 has a role of attaching the end portion of the LED substrate close to the first lid portion 20 and attaching the end portion of the LED substrate close to the second lid portion 22. There will be two second board mounting members 16b.

図５は、基板取付部材１６の形状を示す斜視図である。 FIG. 5 is a perspective view showing the shape of the board mounting member 16.

図５（ａ）は、第１基板取付部材１６ａの形状を示す図である。第１基板取付部材１６ａは、全体として、長手方向の長さＬ１、幅Ｗ２及び厚さＴで表される板体であり、樹脂等の材料から形成される。第１基板取付部材１６ａは、その表面３０ａ上に、第１止めピン３２ａ及び第２止めピン３２ｂの２つの止めピンと、第１壁部３６ａ及び第２壁部３６ｂを含む第１規制部材と、第１壁部３８ａ及び第２壁部３８ｂを含む第２規制部材とを有する。 FIG. 5A is a diagram showing the shape of the first substrate mounting member 16a. The first substrate mounting member 16a is a plate body represented by a length L1, a width W2, and a thickness T in the longitudinal direction as a whole, and is formed of a material such as resin. The first board mounting member 16a has two stop pins, a first stop pin 32a and a second stop pin 32b, and a first regulation member including a first wall portion 36a and a second wall portion 36b on the surface 30a. It has a second regulatory member including a first wall portion 38a and a second wall portion 38b.

第１止めピン３２ａは、図４に示すように、第１ＬＥＤ基板１４ａに形成されている、端部１４３側の貫通孔１４１に係合する。図３を参照すると、第１止めピン３２ａは、表面３０ａから立設する軸部３２ａ_１と、軸部３２ａ_１の先端部に互いに向かい合うように連接された２つの爪部３２ａ_２，３２ａ_３とを有する。この構造によれば、貫通孔１４１に第１止めピン３２ａを係合させるときには、２つの爪部３２ａ_２，３２ａ_３は、貫通孔１４１の開口径に合わせて互いに近接するように変形しながら、貫通孔１４１内を進行する。そして、第１基板取付部材１６ａの表面３０ａと第１ＬＥＤ基板１４ａの裏面１４８とが接触したときには、２つの爪部３２ａ_２，３２ａ_３は、完全に貫通孔１４１を通過し、元の形状に戻る。これにより、第１ＬＥＤ基板１４ａの第１基板取付部材１６ａからの離脱が抑止される。 As shown in FIG. 4, the first stop pin 32a engages with the through hole 141 on the end portion 143 side formed in the first LED substrate 14a. Referring to FIG. 3, the first stop pin 32a includes a shaft portion 32a ₁ _{erected from the surface 30a and two claw portions 32a 2} , 32a ₃ connected to the tip portion of the shaft portion 32a _{1 so as to face each other.} Have. According to this structure, when the first stop pin 32a is engaged with the through hole 141, the two claw portions 32a ₂ , 32a ₃ are deformed so as to be close to each other according to the opening diameter of the through hole 141, while being deformed. Proceed through the through hole 141. Then, when the front surface 30a of the first substrate mounting member 16a and the back surface 148 of the first LED substrate 14a come into contact with each other, the two claw portions 32a ₂ , 32a ₃ completely pass through the through holes 141 and return to their original shapes. .. As a result, the detachment of the first LED substrate 14a from the first substrate mounting member 16a is suppressed.

第２止めピン３２ｂは、図４に示すように、第２ＬＥＤ基板１４ｂに形成されている、端部１４４側の貫通孔１４１に係合する。なお、第２止めピン３２ｂの形状は、第１止めピン３２ａと同一である。 As shown in FIG. 4, the second stop pin 32b engages with the through hole 141 on the end 144 side formed in the second LED substrate 14b. The shape of the second stop pin 32b is the same as that of the first stop pin 32a.

ここで、第１基板取付部材１６ａの表面３０ａ上における、第１止めピン３２ａ及び第２止めピン３２ｂの設置位置は、第１ＬＥＤ基板１４ａ及び第２ＬＥＤ基板１４ｂに予め形成されている貫通孔１４１の位置に依存する。すなわち、当該設置位置は、第１ＬＥＤ基板１４ａ及び第２ＬＥＤ基板１４ｂを第１基板取付部材１６ａに取り付けたときに、図４に示すように、端部１４３又は端部１４４に隣設した貫通孔１４１の位置に合うように決定される。また、第１基板取付部材１６ａの長さＬ１は、貫通孔１４１の位置に基づいて決定された第１止めピン３２ａ及び第２止めピン３２ｂの設置位置に合わせて、最低限必要とされる長さを許容するように規定される。その結果、第１基板取付部材１６ａの長さＬ１は、第１ＬＥＤ基板１４ａ又は第２ＬＥＤ基板１４ｂのいずれの長さよりも短くなる。したがって、第１基板取付部材１６ａは、第１ＬＥＤ基板１４ａ又は第２ＬＥＤ基板１４ｂのいずれに対しても、貫通孔１４１を含む裏面１４８の一部の領域にのみ接触することになり、裏面１４８全体には接触しない。 Here, the installation positions of the first stop pin 32a and the second stop pin 32b on the surface 30a of the first board mounting member 16a are the through holes 141 previously formed in the first LED board 14a and the second LED board 14b. It depends on the position. That is, the installation position is the through hole 141 adjacent to the end portion 143 or the end portion 144 as shown in FIG. 4 when the first LED substrate 14a and the second LED substrate 14b are attached to the first substrate mounting member 16a. It is determined to fit the position of. Further, the length L1 of the first board mounting member 16a is the minimum required length according to the installation positions of the first stop pin 32a and the second stop pin 32b determined based on the position of the through hole 141. It is specified to allow it. As a result, the length L1 of the first substrate mounting member 16a is shorter than the length of either the first LED substrate 14a or the second LED substrate 14b. Therefore, the first substrate mounting member 16a comes into contact with either the first LED substrate 14a or the second LED substrate 14b only in a part of the back surface 148 including the through hole 141, and the entire back surface 148 is covered. Does not touch.

第１規制部材は、第１止めピン３２ａの軸部３２ａ_１を回転軸として第１ＬＥＤ基板１４ａが回転変位することを抑止する。第１規制部材を構成する第１壁部３６ａ及び第２壁部３６ｂは、図３に示すように、互いに向かい合う内壁間の距離Ｗ３が第１ＬＥＤ基板１４ａの幅Ｗ１よりも若干広くなるように設置される。これにより、第１ＬＥＤ基板１４ａが軸部３２ａ_１を回転軸として回転しようとしても、第１ＬＥＤ基板１４ａの側部１４５が第１壁部３６ａの内壁に接触するか、又は、第１ＬＥＤ基板１４ａの側部１４６が第２壁部３６ｂの内壁に接触する。したがって、第１ＬＥＤ基板１４ａの大きな回転変位は抑止される。なお、第１壁部３６ａ及び第２壁部３６ｂの長手方向の長さは任意であるが、軽量化等の観点から、可能な限り短い方が望ましい。 The first regulating member suppresses the rotational displacement of the first LED substrate 14a with _{the shaft portion 32a 1} of the first stop pin 32a as the rotation axis. As shown in FIG. 3, the first wall portion 36a and the second wall portion 36b constituting the first regulating member are installed so that the distance W3 between the inner walls facing each other is slightly wider than the width W1 of the first LED substrate 14a. Will be done. As a result, _{even if the first LED board 14a tries to rotate with the shaft portion 32a 1} as the rotation axis, the side portion 145 of the first LED board 14a comes into contact with the inner wall of the first wall portion 36a, or the side of the first LED board 14a. The portion 146 contacts the inner wall of the second wall portion 36b. Therefore, a large rotational displacement of the first LED substrate 14a is suppressed. The length of the first wall portion 36a and the second wall portion 36b in the longitudinal direction is arbitrary, but it is desirable that the length is as short as possible from the viewpoint of weight reduction and the like.

第２規制部材は、第２止めピン３２ｂの軸部３２ａ_１を回転軸として第２ＬＥＤ基板１４ｂが回転変位することを抑止する。第２規制部材による第２ＬＥＤ基板１４ｂの回転変位の抑止原理は、第１規制部材と同様である。 The second regulating member suppresses the rotational displacement of the second LED substrate 14b with _{the shaft portion 32a 1} of the second stop pin 32b as the rotation axis. The principle of suppressing the rotational displacement of the second LED substrate 14b by the second regulating member is the same as that of the first regulating member.

第１基板取付部材１６ａの幅Ｗ２は、第１に、表面３０ａ上に第１ＬＥＤ基板１４ａ等の裏面１４８と接触する領域を確保するために、第１ＬＥＤ基板１４ａ等の幅Ｗ１よりも大きい。 First, the width W2 of the first substrate mounting member 16a is larger than the width W1 of the first LED substrate 14a or the like in order to secure an area on the front surface 30a that comes into contact with the back surface 148 of the first LED substrate 14a or the like.

また、カバー１８は、図３に示すように、変形された環状の断面形状を有する。具体的には、カバー１８は、内部にＬＥＤ１２から照射された光を受ける空間Ｓ１を形成し、外部へ光を拡散させる拡散部１８ａと、第１基板取付部材１６ａを保持する保持部１８ｂとを含む。特に、保持部１８ｂの断面形状は、直管形状のカバー１８に対して、第１ＬＥＤ基板１４ａを取り付けた第１基板取付部材１６ａを単に差し込むことで固定することが可能なように、第１基板取付部材１６ａを摩擦により保持可能とすることが望ましい。そこで、保持部１８ｂは、第１基板取付部材１６ａの表面３０ａに接触する第１突出部１８ｃと、第１基板取付部材１６ａの裏面３０ｂに接触する第２突出部１８ｄとを有する。この構成によれば、カバー１８に差し込まれた後の第１基板取付部材１６ａは、第１突出部１８ｃと第２突出部１８ｄとに挟まれることにより、カバー１８に接触保持される。したがって、第２に、第１基板取付部材１６ａの幅Ｗ２は、第１基板取付部材１６ａの側部１４５，１４６の側に、それぞれ、第１突出部１８ｃと第２突出部１８ｄとに挟まれる領域を確保可能な値とする。 Further, as shown in FIG. 3, the cover 18 has a deformed annular cross-sectional shape. Specifically, the cover 18 forms a space S1 that receives the light emitted from the LED 12 inside, and has a diffusion portion 18a that diffuses the light to the outside and a holding portion 18b that holds the first substrate mounting member 16a. include. In particular, the cross-sectional shape of the holding portion 18b is such that the first substrate can be fixed to the straight tube-shaped cover 18 by simply inserting the first substrate mounting member 16a to which the first LED substrate 14a is attached. It is desirable that the mounting member 16a can be held by friction. Therefore, the holding portion 18b has a first protruding portion 18c that contacts the front surface 30a of the first substrate mounting member 16a and a second protruding portion 18d that contacts the back surface 30b of the first board mounting member 16a. According to this configuration, the first substrate mounting member 16a after being inserted into the cover 18 is held in contact with the cover 18 by being sandwiched between the first protruding portion 18c and the second protruding portion 18d. Therefore, secondly, the width W2 of the first board mounting member 16a is sandwiched between the first protruding portion 18c and the second protruding portion 18d, respectively, on the sides of the side portions 145 and 146 of the first board mounting member 16a. Set the area to a value that can be secured.

一方、第１基板取付部材１６ａの厚さＴは、第１に、第１ＬＥＤ基板１４ａ等を保持しても破壊しない程度の強度が得られる値とする。また、第２に、第１基板取付部材１６ａの厚さＴは、第１突出部１８ｃと第２突出部１８ｄとで挟むことでカバー１８が接触保持可能な値とする。 On the other hand, the thickness T of the first substrate mounting member 16a is set to a value at which strength that does not break even if the first LED substrate 14a or the like is held is obtained. Secondly, the thickness T of the first substrate mounting member 16a is set to a value at which the cover 18 can be contact-held by being sandwiched between the first protruding portion 18c and the second protruding portion 18d.

また、第１基板取付部材１６ａの長手方向の端部３４，３５の形状は、それぞれ、テーパ状である。この形状により、第１基板取付部材１６ａをカバー１８に差し込む際、第１基板取付部材１６ａが第１突出部１８ｃと第２突出部１８ｄとの間に進入し易くなる。 Further, the shapes of the ends 34 and 35 in the longitudinal direction of the first substrate mounting member 16a are tapered, respectively. Due to this shape, when the first board mounting member 16a is inserted into the cover 18, the first board mounting member 16a easily enters between the first protruding portion 18c and the second protruding portion 18d.

なお、第１基板取付部材１６ａの裏面３０ｂの形状は、上記のような条件を満たすことができるのであれば、特に限定されない。 The shape of the back surface 30b of the first substrate mounting member 16a is not particularly limited as long as the above conditions can be satisfied.

図５（ｂ）は、第２基板取付部材１６ｂの形状を示す図である。第２基板取付部材１６ｂは、全体として、長手方向の長さＬ２、幅Ｗ２及び厚さＴで表される板体であり、樹脂等の材料から形成される。第２基板取付部材１６ｂは、その表面４０ａ上に、止めピン４２と、第１壁部４６ａ及び第２壁部４６ｂを含む第１規制部材と、第１壁部４８ａ及び第２壁部４８ｂを含む第２規制部材とを有する。 FIG. 5B is a diagram showing the shape of the second substrate mounting member 16b. The second substrate mounting member 16b is a plate body represented by a length L2, a width W2, and a thickness T in the longitudinal direction as a whole, and is formed of a material such as resin. The second board mounting member 16b has a stop pin 42, a first regulatory member including a first wall portion 46a and a second wall portion 46b, and a first wall portion 48a and a second wall portion 48b on the surface 40a. It has a second regulatory member including.

ここで、第２基板取付部材１６ｂの幅Ｗ２及び厚さＴは、第１基板取付部材１６ａの幅Ｗ２及び厚さＴと同様である。一方、第２基板取付部材１６ｂは、１つのＬＥＤ基板のみを取り付け対象とすることから、第２基板取付部材１６ｂの長さＬ２は、第１基板取付部材１６ａの長さＬ１よりも短くてもよい。 Here, the width W2 and the thickness T of the second board mounting member 16b are the same as the width W2 and the thickness T of the first board mounting member 16a. On the other hand, since the second board mounting member 16b targets only one LED board, the length L2 of the second board mounting member 16b may be shorter than the length L1 of the first board mounting member 16a. good.

止めピン４２の形状は、第１止めピン３２ａ等の形状と同様である。また、第２基板取付部材１６ｂは、上記のとおり、１つのＬＥＤ基板のみを取り付け対象とするので、表面４０ａ上の長手方向における止めピン４２の設置位置も、任意である。 The shape of the stop pin 42 is the same as the shape of the first stop pin 32a and the like. Further, since the second board mounting member 16b targets only one LED board as described above, the mounting position of the stop pin 42 in the longitudinal direction on the surface 40a is also arbitrary.

また、第２基板取付部材１６ｂの第１規制部材及び第２規制部材についても、第１基板取付部材１６ａの第１規制部材及び第２規制部材と比較して、構成、表面４０ａ上の配置位置、及び、回転変位の抑止原理は、同様である。さらに、第２基板取付部材１６ｂの長手方向の端部４４，４５の形状も、第１基板取付部材１６ａの端部３４，３５の形状と同様に、それぞれ、テーパ状とすることが望ましい。 Further, the first regulatory member and the second regulatory member of the second substrate mounting member 16b are also configured and arranged on the surface 40a as compared with the first regulatory member and the second regulatory member of the first substrate mounting member 16a. , And the principle of suppressing rotational displacement is the same. Further, it is desirable that the shapes of the ends 44, 45 in the longitudinal direction of the second board mounting member 16b are also tapered, as in the shape of the ends 34, 35 of the first board mounting member 16a.

図６は、基板取付部材１６に代わる、基板取付部材５０の形状を示す斜視図である。 FIG. 6 is a perspective view showing the shape of the board mounting member 50 instead of the board mounting member 16.

図６（ａ）は、第１基板取付部材１６ａと同様に、基板取付部材５０を第１ＬＥＤ基板１４ａと第２ＬＥＤ基板１４ｂとを連結させる基板連結部材として機能するように使用する場合の状態を示す図である。基板取付部材５０は、全体として、長手方向の長さＬ３、幅Ｗ２及び厚さＴで表される板体であり、樹脂等の材料から形成される。 FIG. 6A shows a state in which the board mounting member 50 is used to function as a board connecting member for connecting the first LED board 14a and the second LED board 14b, similarly to the first board mounting member 16a. It is a figure. The substrate mounting member 50 is a plate body represented by a length L3, a width W2, and a thickness T in the longitudinal direction as a whole, and is formed of a material such as resin.

ここで、基板取付部材５０は、主として、長手方向の任意の位置で、かつ、幅方向に沿って形成される切り欠き部５２を有する点が第１基板取付部材１６ａと異なる。切り欠き部５２の厚さは、基板取付部材５０全体の厚さ厚さＴよりも薄い。 Here, the board mounting member 50 is different from the first board mounting member 16a in that it mainly has a notch 52 formed at an arbitrary position in the longitudinal direction and along the width direction. The thickness of the notch 52 is thinner than the thickness T of the entire board mounting member 50.

基板取付部材５０は、切り欠き部５２を境界として、第１部分５０ａと、第２部分５０ｂとを含む。長手方向について、基板取付部材５０の長さＬ３に対して、第１部分５０ａの長さはＬ４で表され、第２部分５０ｂの長さはＬ５で表される。 The board mounting member 50 includes a first portion 50a and a second portion 50b with the notch 52 as a boundary. In the longitudinal direction, the length of the first portion 50a is represented by L4 and the length of the second portion 50b is represented by L5 with respect to the length L3 of the substrate mounting member 50.

第１部分５０ａは、その表面６０ａ上に、第１止めピン６２と、第１壁部６６ａ及び第２壁部６６ｂを含む第１規制部材と、第１壁部６８ａ及び第２壁部６８ｂを含む第２規制部材とを有する。このうち、第１止めピン６２の形状は、第１止めピン３２ａ等の形状と同様である。また、第１部分５０ａの第１規制部材及び第２規制部材についても、第１基板取付部材１６ａの第１規制部材及び第２規制部材と比較して、構成、及び、回転変位の抑止原理は、同様である。さらに、第１部分５０ａの長手方向の端部６４の形状も、第１基板取付部材１６ａの端部３４，３５の形状と同様に、テーパ状とすることが望ましい。 The first portion 50a has a first stopper pin 62, a first regulatory member including a first wall portion 66a and a second wall portion 66b, and a first wall portion 68a and a second wall portion 68b on the surface 60a. It has a second regulatory member including. Of these, the shape of the first stop pin 62 is the same as the shape of the first stop pin 32a and the like. Further, the first regulatory member and the second regulatory member of the first portion 50a are also configured and the principle of suppressing rotational displacement is different from that of the first regulatory member and the second regulatory member of the first substrate mounting member 16a. , The same is true. Further, it is desirable that the shape of the end portion 64 in the longitudinal direction of the first portion 50a is also tapered in the same shape as the shape of the ends portions 34 and 35 of the first substrate mounting member 16a.

第２部分５０ｂは、その表面７０ａ上に、第１止めピン７２と、第１壁部７６ａ及び第２壁部７６ｂを含む第１規制部材と、第１壁部７８ａ及び第２壁部７８ｂを含む第２規制部材とを有する。このうち、第１止めピン７２の形状は、第１止めピン３２ａ等の形状と同様である。また、第２部分５０ｂの第１規制部材及び第２規制部材についても、第１基板取付部材１６ａの第１規制部材及び第２規制部材と比較して、構成、及び、回転変位の抑止原理は、同様である。さらに、第２部分５０ｂの長手方向の端部７４の形状も、第１基板取付部材１６ａの端部３４，３５の形状と同様に、テーパ状とすることが望ましい。 The second portion 50b has a first stopper pin 72, a first regulatory member including a first wall portion 76a and a second wall portion 76b, and a first wall portion 78a and a second wall portion 78b on the surface 70a. It has a second regulatory member including. Of these, the shape of the first stop pin 72 is the same as the shape of the first stop pin 32a and the like. Further, the first regulating member and the second regulating member of the second portion 50b are also configured and the principle of suppressing rotational displacement is different from that of the first regulating member and the second regulating member of the first substrate mounting member 16a. , The same is true. Further, it is desirable that the shape of the end portion 74 in the longitudinal direction of the second portion 50b is also tapered in the same shape as the shape of the ends portions 34 and 35 of the first substrate mounting member 16a.

ここで、表面６０ａ又は表面７０ａ上における、第１止めピン６２及び第１止めピン７２の設置位置は、第１基板取付部材１６ａと同様に、第１ＬＥＤ基板１４ａ及び第２ＬＥＤ基板１４ｂに予め形成されている貫通孔１４１の位置に依存する。すなわち、当該設置位置は、第１基板取付部材１６ａにおいて第１止めピン３２ａ及び第２止めピン３２ｂの設置位置を決定するのと同様に決定され得る。また、基板取付部材５０の長さＬ３も、第１止めピン６２及び第１止めピン７２の設置位置に合わせて、最低限必要とされる長さを許容するように規定される。したがって、第１止めピン６２及び第１止めピン７２を基準とすれば、切り欠き部５２は、第１の止めピン６２と第２の止めピン７２とに挟まれた領域を横切るように形成されるということができる。 Here, the installation positions of the first stop pin 62 and the first stop pin 72 on the surface 60a or the surface 70a are formed in advance on the first LED board 14a and the second LED board 14b, similarly to the first board mounting member 16a. It depends on the position of the through hole 141. That is, the installation position can be determined in the same manner as the installation position of the first stop pin 32a and the second stop pin 32b in the first board mounting member 16a. Further, the length L3 of the board mounting member 50 is also specified so as to allow the minimum required length according to the installation positions of the first stop pin 62 and the first stop pin 72. Therefore, based on the first stop pin 62 and the first stop pin 72, the notch 52 is formed so as to cross the region sandwiched between the first stop pin 62 and the second stop pin 72. Can be said.

図６（ｂ）は、基板取付部材５０を、切り欠き部５２を破断領域として分割した状態を示す図である。切り欠き部５２の厚さＴ１は、上記のとおり、基板取付部材５０全体の厚さＴよりも薄い。そのため、作業者は、第２部分５０ｂを保持しつつ、矢印方向に示すように第１部分５０ａに力を加えることにより、切り欠き部５２の部分から基板取付部材５０を破断し、第１部分５０ａと第２部分５０ｂとを別体とすることができる。このように分割された第１部分５０ａ及び第２部分５０ｂは、いずれも第２基板取付部材１６ｂと類似した形状となる。すなわち、分割された第１部分５０ａ又は第２部分５０ｂのいずれかを第２基板取付部材１６ｂと同様に用いることができる。 FIG. 6B is a diagram showing a state in which the substrate mounting member 50 is divided with the cutout portion 52 as a fracture region. As described above, the thickness T1 of the cutout portion 52 is thinner than the thickness T of the entire board mounting member 50. Therefore, the operator breaks the board mounting member 50 from the notch 52 by applying a force to the first portion 50a as shown in the direction of the arrow while holding the second portion 50b, and the first portion. The 50a and the second portion 50b can be separated. Both the first portion 50a and the second portion 50b thus divided have a shape similar to that of the second substrate mounting member 16b. That is, either the divided first portion 50a or the second portion 50b can be used in the same manner as the second substrate mounting member 16b.

なお、分割前に切り欠き部５２であった端部について、第１部分５０ａ側の端部５２ａと、第２部分５０ｂ側の端部５２ｂとは、切り欠き部５２の切り欠き形状に基づいて、自ずとテーパ状となる。したがって、分割後に各端部５２ａ，５２ｂをテーパ加工する必要はない。 Regarding the end portion that was the notch portion 52 before the division, the end portion 52a on the first portion 50a side and the end portion 52b on the second portion 50b side are based on the notch shape of the notch portion 52. , It naturally becomes tapered. Therefore, it is not necessary to taper the ends 52a and 52b after the division.

次に、本実施形態に係る照明器具１０と比較するため、従来の照明器具１００の構成について説明する。 Next, in order to compare with the luminaire 10 according to the present embodiment, the configuration of the conventional luminaire 100 will be described.

図７は、照明器具１００の内部構成を示す斜視図である。なお、図７において、照明器具１０と同一の構成とし得るものには同一の符号を付し、説明を省略する。また、図７では、本実施形態に係る図２と同様に、第１蓋部２０からカバー１８を長手方向に引き抜いた照明器具１００の分解状態を示している。 FIG. 7 is a perspective view showing the internal configuration of the luminaire 100. In FIG. 7, the same reference numerals are given to those having the same configuration as the lighting fixture 10, and the description thereof will be omitted. Further, FIG. 7 shows a disassembled state of the luminaire 100 in which the cover 18 is pulled out from the first lid portion 20 in the longitudinal direction, as in FIG. 2 according to the present embodiment.

ここで、複数のＬＥＤ１２を実装している第１ＬＥＤ基板１４ａや、カバー１８の構成及び形状は、本実施形態と同様であると仮定する。これに対して、照明器具１００は、特に、亜鉛鋼板等の材料で形成され、第１ＬＥＤ基板１４ａ等のＬＥＤ基板の全長に合う長さを有する基板取付板１１０を含む。 Here, it is assumed that the configuration and shape of the first LED substrate 14a on which the plurality of LEDs 12 are mounted and the cover 18 are the same as those in the present embodiment. On the other hand, the luminaire 100 includes a substrate mounting plate 110 which is made of a material such as a galvanized steel plate and has a length corresponding to the total length of the LED substrate such as the first LED substrate 14a.

基板取付板１１０は、その表面上に、第１ＬＥＤ基板１４ａを取り付ける。ここで、図７では不図示であるが、第１ＬＥＤ基板１４ａには、上記本実施形態の説明でも述べたとおり、予めＬＥＤ基板取り付け用の貫通孔１４１が形成されている。そして、従来、第１ＬＥＤ基板１４ａは、貫通孔１４１を用いたネジ１２０による締結により、基板取付板１１０に取り付けられていた。 The first LED board 14a is mounted on the surface of the board mounting plate 110. Here, although not shown in FIG. 7, the first LED substrate 14a is preliminarily formed with a through hole 141 for mounting the LED substrate, as described in the above description of the present embodiment. Conventionally, the first LED substrate 14a has been attached to the substrate mounting plate 110 by fastening with screws 120 using the through holes 141.

また、基板取付板１１０は、カバー１８に差し込まれ、第１突出部１８ｃと第２突出部１８ｄとに挟まれることにより、カバー１８に接触保持される。したがって、特に基板取付板１１０の幅は、第１突出部１８ｃと第２突出部１８ｄとに挟まれる領域を確保可能な値とすることが望ましく、例えば、第１基板取付部材１６ａの幅Ｗ２と同様とし得る。 Further, the board mounting plate 110 is inserted into the cover 18 and is sandwiched between the first protruding portion 18c and the second protruding portion 18d, so that the board mounting plate 110 is contacted and held by the cover 18. Therefore, it is particularly desirable that the width of the board mounting plate 110 is set to a value that can secure a region sandwiched between the first protruding portion 18c and the second protruding portion 18d, and for example, the width W2 of the first board mounting member 16a. It can be similar.

次に、照明器具１０による効果について説明する。 Next, the effect of the lighting fixture 10 will be described.

本実施形態に係る照明器具１０は、光源が長手方向に配列されている基板と、基板を取り付ける基板取付部材１６と、基板取付部材１６を接触保持するカバー１８とを備える。基板は、長手方向の端部に隣設された貫通孔１４１を有する。基板取付部材１６は、基板の貫通孔１４１を含む一部の領域に接触する。 The lighting fixture 10 according to the present embodiment includes a substrate in which light sources are arranged in the longitudinal direction, a substrate mounting member 16 for mounting the substrate, and a cover 18 for contacting and holding the substrate mounting member 16. The substrate has a through hole 141 adjacent to the end in the longitudinal direction. The board mounting member 16 contacts a part of the area including the through hole 141 of the board.

ここで、光源は、例えばＬＥＤ１２である。この場合、基板は、第１ＬＥＤ基板１４ａ又は第２ＬＥＤ基板１４ｂ等のＬＥＤ基板である。 Here, the light source is, for example, LED12. In this case, the substrate is an LED substrate such as the first LED substrate 14a or the second LED substrate 14b.

従来、図７に示したように、ＬＥＤ基板の取り付けには、その全長に合う長さを有し、亜鉛鋼板等の材料で形成されている基板取付板１１０が用いられていた。そのため、基板取付板１１０の重量が、照明器具１００全体の重量のうち大きな比率を占めていた。これに対して、本実施形態に係る照明器具１０によれば、基板取付板１１０に代えて、ＬＥＤ基板の固定又は係合に用いられ得る貫通孔１４１を含む領域にのみ接触する基板取付部材１６が用いられる。このように規定された基板取付部材１６の長手方向の長さＬ１は、従来の基板取付板１１０の長手方向の長さよりも短くなる。これにより、基板取付部材１６の重量は、基板取付板１１０よりも減少するので、その結果、照明器具１０全体の軽量化が実現される。 Conventionally, as shown in FIG. 7, a substrate mounting plate 110 having a length corresponding to the total length of the LED substrate and being made of a material such as a galvanized steel plate has been used for mounting the LED substrate. Therefore, the weight of the board mounting plate 110 occupies a large proportion of the weight of the entire lighting fixture 100. On the other hand, according to the lighting fixture 10 according to the present embodiment, the board mounting member 16 that contacts only the region including the through hole 141 that can be used for fixing or engaging the LED board instead of the board mounting plate 110. Is used. The length L1 in the longitudinal direction of the board mounting member 16 defined in this way is shorter than the length in the longitudinal direction of the conventional board mounting plate 110. As a result, the weight of the board mounting member 16 is smaller than that of the board mounting plate 110, and as a result, the weight of the entire lighting fixture 10 is reduced.

なお、このような軽量化によれば、例えば、基板取付部材の材料費が抑えられることになり、結果として、照明器具１０の製造コストの抑制にも寄与する。また、従来の基板取付板１１０は、いわゆる板金部品であったが、本実施形態における基板取付部材１６を樹脂部品とすることで、より軽量化が図れる。 In addition, according to such weight reduction, for example, the material cost of the substrate mounting member can be suppressed, and as a result, it also contributes to the reduction of the manufacturing cost of the lighting fixture 10. Further, the conventional board mounting plate 110 is a so-called sheet metal part, but by using the board mounting member 16 in the present embodiment as a resin part, the weight can be further reduced.

一方、軽量化のためと称して、従来の照明器具１００から単に基板取付板１１０を取り除くことも考えられる。しかし、ＬＥＤ基板の幅Ｗ１は、基板取付板１１０の幅Ｗ２よりも短いため、ＬＥＤ基板１４は、カバー１８の第１突出部１８ｃと第２突出部１８ｄとに到達することができない。すなわち、この場合、カバー１８の形状が予め規定されている場合に、対応することができない。これに対して、本実施形態によれば、基板取付部材１６は、カバー１８によって接触保持される程度の幅Ｗ２を確保することができるので、カバー１８の形状が予め規定されている場合でも採用可能である。 On the other hand, it is also conceivable to simply remove the board mounting plate 110 from the conventional lighting fixture 100 for the purpose of weight reduction. However, since the width W1 of the LED board is shorter than the width W2 of the board mounting plate 110, the LED board 14 cannot reach the first protruding portion 18c and the second protruding portion 18d of the cover 18. That is, in this case, if the shape of the cover 18 is predetermined, it cannot be dealt with. On the other hand, according to the present embodiment, the board mounting member 16 can secure a width W2 sufficient to be contact-held by the cover 18, so that the board mounting member 16 is adopted even when the shape of the cover 18 is predetermined. It is possible.

また、本実施形態に係る照明器具１０では、基板取付部材１６は、貫通孔１４１に係合して基板の離脱を抑止する止めピンを有する。 Further, in the lighting fixture 10 according to the present embodiment, the board mounting member 16 has a stop pin that engages with the through hole 141 to prevent the board from coming off.

本実施形態に係る照明器具１０によれば、例えば、ＬＥＤ基板が既存である場合、基板取付部材１６は、すでにＬＥＤ基板に形成されているネジ穴を貫通孔１４１として利用して、ＬＥＤ基板を取り付けることができる。すなわち、カバー１８の他、ＬＥＤ基板も既存のものを利用する照明器具であっても、本実施形態を適用することが可能となる。換言すれば、本実施形態を適用させるために、カバー１８やＬＥＤ基板を新たに製作する必要はない。 According to the lighting fixture 10 according to the present embodiment, for example, when the LED board already exists, the board mounting member 16 utilizes the screw hole already formed in the LED board as the through hole 141 to form the LED board. Can be attached. That is, the present embodiment can be applied to a lighting fixture that uses an existing LED substrate in addition to the cover 18. In other words, it is not necessary to newly manufacture the cover 18 or the LED substrate in order to apply the present embodiment.

また、基板取付部材１６に直接的に止めピンを設けることで、基板取付部材１６は、別途ネジを用いることなく、容易にＬＥＤ基板を取り付けることができる。 Further, by providing the fixing pin directly on the board mounting member 16, the board mounting member 16 can easily mount the LED board without using a separate screw.

また、本実施形態に係る照明器具１０では、基板は、第１の基板と、第２の基板とを含む。このとき、基板取付部材は、第１の基板に形成されている貫通孔に係合して基板の離脱を抑止する第１の止めピンと、第２の基板に形成されている貫通孔に係合して基板の離脱を抑止する第２の止めピンとを有する。そして、基板取付部材は、第１の基板と第２の基板とを長手方向に連結する。 Further, in the lighting fixture 10 according to the present embodiment, the substrate includes a first substrate and a second substrate. At this time, the substrate mounting member engages with the first stop pin that engages with the through hole formed in the first substrate to prevent the substrate from coming off, and engages with the through hole formed in the second substrate. It also has a second stop pin that prevents the substrate from coming off. Then, the substrate mounting member connects the first substrate and the second substrate in the longitudinal direction.

ここで、第１の基板は、例えば第１ＬＥＤ基板１４ａである。第２の基板は、例えば第２ＬＥＤ基板１４ｂである。特に、この場合の基板取付部材は、例えば、第１基板取付部材１６ａに相当し、第１の止めピンは、例えば第１止めピン３２ａに相当し、第２の止めピンは、例えば第２止めピン３２ｂに相当する。 Here, the first substrate is, for example, the first LED substrate 14a. The second substrate is, for example, the second LED substrate 14b. In particular, the board mounting member in this case corresponds to, for example, the first board mounting member 16a, the first stop pin corresponds to, for example, the first stop pin 32a, and the second stop pin corresponds to, for example, the second stop. Corresponds to pin 32b.

本実施形態に係る照明器具１０によれば、照明器具１０内のＬＥＤ基板が複数存在していたとしても、基板取付部材は、それらのＬＥＤ基板を長手方向に沿って連結させることができる。これにより、例えば、作業者は、カバー１８に対する基板取付部材の差し込みや抜き出しを容易に行うことが可能となる。 According to the luminaire 10 according to the present embodiment, even if a plurality of LED substrates in the luminaire 10 exist, the substrate mounting member can connect the LED substrates along the longitudinal direction. As a result, for example, the operator can easily insert and remove the board mounting member from the cover 18.

また、本実施形態に係る照明器具１０では、基板取付部材１６は、基板を取り付ける表面上に、基板の長手方向に沿って立設し、貫通孔１４１に止めピンが係合しているときに基板の側部に内壁が対向する壁部を有する。 Further, in the lighting fixture 10 according to the present embodiment, the board mounting member 16 is erected on the surface on which the board is mounted along the longitudinal direction of the board, and when the stop pin is engaged with the through hole 141. The side portion of the substrate has a wall portion on which the inner wall faces.

ここで、基板取付部材１６が第１基板取付部材１６ａであるとすると、例えば、止めピンは、第１止めピン３２ａに相当し、壁部は、第１規制部材を構成する第１壁部３６ａ及び第２壁部３６ｂに相当する。 Here, assuming that the board mounting member 16 is the first board mounting member 16a, for example, the stop pin corresponds to the first stop pin 32a, and the wall portion is the first wall portion 36a constituting the first regulation member. And corresponds to the second wall portion 36b.

上記のように、貫通孔１４１に第１止めピン３２ａが係合している状態では、例えば、第１止めピン３２ａの軸部３２ａ_１を回転軸として第１ＬＥＤ基板１４ａが回転変位することも考えられる。これに対して、本実施形態に係る照明器具１０によれば、このように第１ＬＥＤ基板１４ａが回転変位しようとしても、第１ＬＥＤ基板１４ａの側部のいずれかと、第１壁部３６ａ又は第２壁部３６ｂの内壁のいずれかとが接触する。したがって、第１ＬＥＤ基板１４ａの回転変位が抑止される。これにより、基板取付部材１６に対するＬＥＤ基板の姿勢がより安定化されるので、作業者による基板取付部材の差し込みや抜き出しが、より容易となる。 As described above, in a state where the first stop pin 32a is engaged with the through hole 141, for example, it is conceivable that the first LED substrate 14a is rotationally displaced with _{the shaft portion 32a 1 of the first stop pin 32a as the rotation axis.} Be done. On the other hand, according to the lighting fixture 10 according to the present embodiment, even if the first LED substrate 14a tries to be rotationally displaced in this way, any of the side portions of the first LED substrate 14a and the first wall portion 36a or the second wall portion 36a or the second. It comes into contact with any of the inner walls of the wall portion 36b. Therefore, the rotational displacement of the first LED substrate 14a is suppressed. As a result, the posture of the LED board with respect to the board mounting member 16 is more stabilized, and it becomes easier for the operator to insert and remove the board mounting member.

さらに、本実施形態に係る照明器具１０では、基板取付部材５０は、第１の止めピン６２と第２の止めピン７２とに挟まれた領域を横切る切り欠き部５２を有する。 Further, in the lighting fixture 10 according to the present embodiment, the substrate mounting member 50 has a notch 52 that crosses a region sandwiched between the first stop pin 62 and the second stop pin 72.

本実施形態に係る照明器具１０によれば、基板取付部材として、２つのＬＥＤ基板を連結させるものと、単に１つのＬＥＤ基板を取り付けるものとの２種類を準備する必要がない。すなわち、この構成によれば、２つのＬＥＤ基板を連結させるものとして用いる場合には、基板取付部材５０をそのまま利用する。一方、単に１つのＬＥＤ基板を取り付けるものとして用いる場合には、切り欠き部５２から基板取付部材５０を２つに分割し、分割された第１部分５０ａ又は第２部分５０ｂのいずれかを利用すればよい。 According to the lighting fixture 10 according to the present embodiment, it is not necessary to prepare two types of board mounting members, one for connecting two LED boards and the other for simply mounting one LED board. That is, according to this configuration, when the two LED boards are used to be connected, the board mounting member 50 is used as it is. On the other hand, when it is used simply for mounting one LED board, the board mounting member 50 is divided into two from the notch 52, and either the divided first portion 50a or the second portion 50b is used. Just do it.

以上、好ましい実施形態について説明したが、本実施形態は、これ限定されず、その要旨の範囲内で種々の変形及び変更が可能である。 Although the preferred embodiment has been described above, the present embodiment is not limited thereto, and various modifications and changes can be made within the scope of the gist thereof.
