The width of each groove 213 in the width direction is constant over the entire length in the longitudinal direction. In other words, the fixed portion 21 is formed with a linear opening 214 having a constant width continuous in the longitudinal direction.

図1に示すように、各発光部3では、薄い矩形の基板31上に複数のLEDチップ(1つのLEDチップのみであってもよい。)が実装され、複数のLEDチップは樹脂にて封入(モールド)される。図1および図2では、当該樹脂に符号33を付している。また、矩形の基板31における1組の対角近傍には2つの貫通孔34がそれぞれ形成される。Z方向において2つの貫通孔34は2つの溝213の開口214と重なり、雄ねじ35が貫通孔34を介して溝213内に挿入される。図2では、二点鎖線にて雄ねじ35を図示している。   As shown in FIG. 1, in each light emitting part 3, a plurality of LED chips (only one LED chip may be provided) are mounted on a thin rectangular substrate 31, and the plurality of LED chips are encapsulated with resin. (Molded). In FIG. 1 and FIG. 2, the reference numeral 33 is attached to the resin. Further, two through holes 34 are formed in the vicinity of a pair of diagonals in the rectangular substrate 31. In the Z direction, the two through holes 34 overlap the openings 214 of the two grooves 213, and the male screw 35 is inserted into the groove 213 through the through holes 34. In FIG. 2, the male screw 35 is illustrated by a two-dot chain line.

本実施の形態では、雄ねじ35はメートルねじ等であり、固定部21の溝213の幅は雄ねじ35の軸径(直径)におよそ等しく、溝213の内部の2つの側面には雄ねじ35のねじ山に対応する形状の微小溝が形成される。そして、雄ねじ35が溝213に螺合されることにより、各発光部3が固定部21に固定される。もちろん、タップタイト(登録商標)ねじやタッピンねじである雄ねじが用いられることにより、溝213の内部の側面に微小溝を予め形成することなく、雄ねじが溝213にねじ込まれて発光部3が固定部21に固定されてもよい。なお、これらのねじの溝213内へのねじ込みは螺合の一態様である。   In the present embodiment, the male screw 35 is a metric screw or the like, the width of the groove 213 of the fixed portion 21 is approximately equal to the shaft diameter (diameter) of the male screw 35, and the screw of the male screw 35 is provided on the two side surfaces inside the groove 213. A minute groove having a shape corresponding to the mountain is formed. Then, each light emitting portion 3 is fixed to the fixing portion 21 by the male screw 35 being screwed into the groove 213. Of course, by using a male screw such as a tap tight (registered trademark) screw or a tapping screw, the male screw is screwed into the groove 213 and the light emitting part 3 is fixed without forming a micro groove in advance in the side surface of the groove 213. It may be fixed to the part 21. The screwing of these screws into the groove 213 is one mode of screwing.

図1に示すように、発光部3の基板31上には複数のLEDチップに電気的に接続される2つの端子36が形成される。2つの端子36は、長手方向において複数のLEDチップ(すなわち、樹脂33内のLEDチップ)を挟むように配置される。複数の発光部3において互いに隣接する2つの発光部3では、互いに隣接する2つの端子36に導電線39の両端がそれぞれ半田付けされる。すなわち、複数の発光部3において互いに隣接する2つの発光部3の各組合せが導電線39を介して電気的に接続される。導電線39の直径は開口214の幅とおよそ等しく、または、開口214の幅よりも僅かに小さく、図1および図3に示すように、各導電線39のおよそ全体が、2つの発光部3の間において溝213の内部に挿入されて、導電線39が隠される。   As shown in FIG. 1, two terminals 36 that are electrically connected to a plurality of LED chips are formed on the substrate 31 of the light emitting unit 3. The two terminals 36 are arranged so as to sandwich a plurality of LED chips (that is, LED chips in the resin 33) in the longitudinal direction. In two light emitting units 3 adjacent to each other in the plurality of light emitting units 3, both ends of the conductive wire 39 are soldered to two terminals 36 adjacent to each other. That is, each combination of two light emitting units 3 adjacent to each other in the plurality of light emitting units 3 is electrically connected via the conductive wire 39. The diameter of the conductive line 39 is approximately equal to the width of the opening 214 or slightly smaller than the width of the opening 214, and as shown in FIGS. The conductive line 39 is concealed by being inserted into the groove 213.

複数の発光部3のうち長手方向の端の各発光部3(図1では、最も(+Y)側の発光部3)では、端部カバー42に近接する端子36にも導電線(図1中にて符号39aを付す導電線であり、以下、「終端導電線39a」という。)の一端が接続される。終端導電線39aの他端は固定部21に形成された貫通孔215を介して固定部21とベース部5との間の空間へと導かれ(図2参照)、ベース部5上の電源部61に接続される。このように、複数の発光部3は電源部61に対して直列に接続される。   In each of the light emitting units 3 at the end in the longitudinal direction among the plurality of light emitting units 3 (the light emitting unit 3 on the most (+ Y) side in FIG. 1), a conductive wire (in FIG. 1) is also connected to the terminal 36 adjacent to the end cover 42. , And is connected to one end of a conductive wire denoted by reference numeral 39a. The other end of the terminal conductive line 39a is led to a space between the fixed part 21 and the base part 5 through a through hole 215 formed in the fixed part 21 (see FIG. 2), and the power supply part on the base part 5 61 is connected. As described above, the plurality of light emitting units 3 are connected in series to the power supply unit 61.

長手方向に垂直な本体部2の断面形状は、貫通孔215,224,225(図1および図3参照)が形成された部位を除き、長手方向における全長に亘って同一であり、本体部2の全体(すなわち、固定部21および2つの本体側壁部22)は、例えばアルミニウムやアルミニウム合金の押し出し成形にて一体的にて形成される。貫通孔215,224,225は、押し出し成形後のプレス加工等により形成される。   The cross-sectional shape of the main body 2 perpendicular to the longitudinal direction is the same over the entire length in the longitudinal direction except for the portions where the through holes 215, 224, and 225 (see FIGS. 1 and 3) are formed. (Ie, the fixed portion 21 and the two main body side wall portions 22) are integrally formed by, for example, extrusion molding of aluminum or aluminum alloy. The through holes 215, 224, and 225 are formed by press working after extrusion.

また、図2に示す本体部2の表面は、いわゆる、高反射塗装が施されることにより白色に塗装され、発光部3から出射される光(例えば、白色光)のうち拡散パネル41にて拡散または反射されて固定部21へと入射する光は高い反射率にて反射される。このように、本体部2における固定部21は、複数の発光部3から出射される光を反射する反射板を兼ねており、これにより、LED照明装置1から出射される光の強度が増大される。また、発光部3の基板31の裏面(すなわち、固定部21と対向する主面)には放熱グリースが塗布されており、発光部3にて生じる熱は効率よく固定部21へと導かれ、本体部2の全体にて放熱される。なお、ベース部5は鋼板の板金加工等により形成される。   Further, the surface of the main body 2 shown in FIG. 2 is painted white by applying a so-called highly reflective coating, and the diffusion panel 41 out of the light (for example, white light) emitted from the light emitting unit 3. Light that is diffused or reflected and enters the fixed portion 21 is reflected with a high reflectance. As described above, the fixing portion 21 in the main body portion 2 also serves as a reflecting plate that reflects the light emitted from the plurality of light emitting portions 3, thereby increasing the intensity of the light emitted from the LED lighting device 1. The In addition, heat radiation grease is applied to the back surface of the substrate 31 of the light emitting unit 3 (that is, the main surface facing the fixed unit 21), and heat generated in the light emitting unit 3 is efficiently guided to the fixed unit 21; Heat is dissipated throughout the body 2. The base portion 5 is formed by sheet metal processing of a steel plate.

LED照明装置1を工場や室内等に設置する際には、図2および図3のベース部5の上下を反転した状態にて、ベース部5の固定部21とは反対側の面(正確には、凸状部位53)が、ねじ等により天井に固定される。そして、発光部3の終端導電線39a(図1参照)をベース部5上の電源部61に接続した後に本体部2がベース部5に取り付けられ、ボルト231(図3参照)を貫通孔225,521に螺合することにより、本体部2がベース部5に固定される。このとき、図4に示すように、本体部2の爪部223をベース部5の爪部51に引っ掛けることにより、終端導電線39a(図1参照)と電源部61との接続作業等を行う際に、作業者が本体部2を支持する必要がなくなり、LED照明装置1の設置作業を効率よく行うことができる。   When the LED lighting device 1 is installed in a factory, a room, or the like, the surface of the base portion 5 opposite to the fixed portion 21 (exactly in a state where the base portion 5 in FIGS. 2 and 3 is turned upside down) The convex portion 53) is fixed to the ceiling with screws or the like. And after connecting the terminal conductive line 39a (refer FIG. 1) of the light emission part 3 to the power supply part 61 on the base part 5, the main-body part 2 is attached to the base part 5, and the volt | bolt 231 (refer FIG. 3) is penetrated to the through-hole 225. , 521 and the main body 2 are fixed to the base 5. At this time, as shown in FIG. 4, by hooking the claw portion 223 of the main body portion 2 to the claw portion 51 of the base portion 5, connection work between the terminal conductive wire 39 a (see FIG. 1) and the power source portion 61 is performed. At this time, it is not necessary for the operator to support the main body 2, and the installation work of the LED lighting device 1 can be performed efficiently.

図5は、比較例のLED照明装置の固定部を示す図である。図5に示すように比較例の固定部91では、発光部の固定用の孔911が配列形成され(必要に応じて、さらにバーリング加工が行われる。)、雄ねじを発光部に形成された孔を介して固定部91の孔911に螺合することにより、発光部が固定部91に固定される。比較例の固定部91にて、LED照明装置毎に複数の発光部の間隔を変更する場合には、装置毎に異なるピッチにて固定用の孔911を形成する必要があり、LED照明装置の製造作業が繁雑となる。また、比較例の固定部91では、2つの隣接する発光部間における導電線が固定部91の主面上に位置するため、導電線の長さによっては、導電線が主面から浮き上がって、拡散パネル上に影が映る場合がある。   FIG. 5 is a diagram illustrating a fixing portion of the LED lighting device of the comparative example. As shown in FIG. 5, in the fixing part 91 of the comparative example, holes 911 for fixing the light emitting part are arranged and formed (further burring is performed if necessary), and the male screw is formed in the light emitting part. The light emitting portion is fixed to the fixing portion 91 by being screwed into the hole 911 of the fixing portion 91 via. In the fixing portion 91 of the comparative example, when changing the intervals of the plurality of light emitting portions for each LED lighting device, it is necessary to form fixing holes 911 at different pitches for each device. Manufacturing work becomes complicated. Further, in the fixing portion 91 of the comparative example, the conductive wire between two adjacent light emitting portions is located on the main surface of the fixing portion 91, so that depending on the length of the conductive wire, the conductive wire is lifted from the main surface, Shadows may appear on the diffuser panel.

これに対し、図1のLED照明装置1では、連続する一定幅の直線状の開口214(すなわち、有底溝213の開口)が固定部21に形成され、複数の発光部3のそれぞれに設けられる突起部である雄ねじ35が開口214に螺合されることにより、複数の発光部3が開口214に沿って固定部21に取り付けられる。これにより、LED照明装置1を製造する際に、複数の発光部3を固定部21に所望のピッチにて容易に固定することができ、LED照明装置毎に複数の発光部3のピッチを自在に変更することができる。なお、本実施の形態におけるLED照明装置1では、複数の発光部3を固定部21に固定した後に、導電線39が発光部3の端子36に接続される。   On the other hand, in the LED lighting device 1 of FIG. 1, a continuous linear opening 214 having a constant width (that is, the opening of the bottomed groove 213) is formed in the fixed portion 21 and provided in each of the plurality of light emitting portions 3. The plurality of light emitting portions 3 are attached to the fixing portion 21 along the opening 214 by screwing the male screw 35, which is a protruding portion, into the opening 214. Thereby, when manufacturing the LED lighting apparatus 1, the several light emission part 3 can be easily fixed to the fixing | fixed part 21 with a desired pitch, and the pitch of the several light emission part 3 is free for every LED lighting apparatus. Can be changed. In the LED lighting device 1 according to the present embodiment, the conductive wire 39 is connected to the terminal 36 of the light emitting unit 3 after fixing the plurality of light emitting units 3 to the fixed unit 21.

また、固定部21が、複数の発光部3から出射される光を反射する反射板を兼ねることにより、反射板を個別の部材として設ける場合に比べて、LED照明装置1の構成を簡素化することができる。   Moreover, the structure of the LED illuminating device 1 is simplified compared with the case where the fixing | fixed part 21 serves also as a reflecting plate which reflects the light radiate | emitted from the several light emission part 3, compared with a case where a reflecting plate is provided as an individual member. be able to.

さらに、複数の発光部3において互いに隣接する2つの発光部3の各組合せが導電線39を介して電気的に接続され、当該各組合せにおける導電線39が、当該各組合せにおける2つの発光部3の間において開口214に挿入される。これにより、2つの発光部3間の導電線39を保持することができ、導電線39が固定部21から過度に浮き上がり、影となることを防止することができる。   Furthermore, each combination of two light emitting units 3 adjacent to each other in the plurality of light emitting units 3 is electrically connected via a conductive line 39, and the conductive line 39 in each combination is connected to the two light emitting units 3 in each combination. Is inserted into the opening 214. As a result, the conductive line 39 between the two light emitting units 3 can be held, and the conductive line 39 can be prevented from floating excessively from the fixed unit 21 and becoming a shadow.

LED照明装置1では、本体部2の溝213が他の部位(貫通孔215,224,225を除く。)と共に押し出し成形にて同時に形成されるため、開口214を有する固定部21を容易に作製することが可能である。また、比較例のように発光部の固定用の孔を2次加工にて別途形成する必要がないため、LED照明装置の製造コストを削減することができる。さらに、押し出し成形にて作製された部材を所望の長さにて切断することにより、棒状の蛍光灯を用いる照明装置とは異なり、外形が所望の長さのLED照明装置を容易に製造することができる。   In the LED lighting device 1, the groove 213 of the main body 2 is formed simultaneously with other parts (excluding the through holes 215, 224, and 225) by extrusion molding, so that the fixing part 21 having the opening 214 is easily manufactured. Is possible. Further, unlike the comparative example, it is not necessary to separately form a hole for fixing the light emitting part by secondary processing, and thus the manufacturing cost of the LED lighting device can be reduced. Further, by cutting a member produced by extrusion molding to a desired length, unlike a lighting device using a rod-like fluorescent lamp, an LED lighting device having a desired outer shape can be easily manufactured. Can do.

図6および図7は、LED照明装置の他の例を示す図であり、図6および図7はそれぞれ図1および図2に対応する図である。図6および図7に示すLED照明装置1aでは、図1および図2のLED照明装置1と比較して、固定部21aの中央部211aの形状、および、発光部3aを固定する突起部の形状が相違する。他の構成は、図1および図2のLED照明装置1と同様であり、同符号を付す。   6 and 7 are diagrams showing another example of the LED lighting device, and FIGS. 6 and 7 are diagrams corresponding to FIGS. 1 and 2, respectively. In the LED lighting device 1a shown in FIGS. 6 and 7, as compared with the LED lighting device 1 of FIGS. 1 and 2, the shape of the central portion 211a of the fixing portion 21a and the shape of the protrusion that fixes the light emitting portion 3a Is different. Other configurations are the same as those of the LED lighting device 1 of FIGS. 1 and 2, and are denoted by the same reference numerals.

図6および図7のLED照明装置1aでは、固定部21aの中央部211aがXY平面に平行な板状であり、図1のLED照明装置1と同様に、本体部2aはアルミニウムの押し出し成形にて形成される。中央部211aには、押し出し成形後のプレス加工等により一定幅の複数の開口要素2141が形成される。詳細には、図6に示すように、長手方向(Y方向)に沿って小さいギャップ(非開口部)を設けつつ一列に配列される複数の開口要素2141の集合を開口214aとして、固定部21aには、同様の形状である2つの開口214aが幅方向(X方向)に並んで形成される。このように、各開口214aは断続する一定幅の直線状である。なお、ギャップが小さい場合には、開口214aは実質的に連続する一定幅の直線状と捉えることもできる。   6 and 7, the central portion 211a of the fixed portion 21a has a plate shape parallel to the XY plane. Like the LED lighting device 1 of FIG. 1, the main body 2a is formed by extrusion molding of aluminum. Formed. In the central portion 211a, a plurality of opening elements 2141 having a constant width are formed by press working after extrusion. In detail, as shown in FIG. 6, a set of a plurality of opening elements 2141 arranged in a row while providing a small gap (non-opening portion) along the longitudinal direction (Y direction) is defined as an opening 214a, and the fixing portion 21a. The two openings 214a having the same shape are formed side by side in the width direction (X direction). Thus, each opening 214a is a straight line with a constant width that is intermittent. When the gap is small, the opening 214a can be regarded as a substantially continuous straight line having a constant width.

各発光部3aにおいて基板31に形成される2つの貫通孔34は2つの開口214aとそれぞれ重なる。また、直径が開口要素2141のX方向の幅よりも僅かに大きい突起状のピン35aが、貫通孔34を介して開口214aに圧入される。これにより、発光部3aが固定部21aに固定される。   In each light emitting portion 3a, the two through holes 34 formed in the substrate 31 overlap the two openings 214a, respectively. In addition, a protruding pin 35 a having a diameter slightly larger than the width of the opening element 2141 in the X direction is press-fitted into the opening 214 a through the through hole 34. Thereby, the light emission part 3a is fixed to the fixing | fixed part 21a.

このように、図6のLED照明装置1aでは、断続する一定幅の直線状の開口214aが固定部21aに形成され、各発光部3aに設けられる突起部であるピン35aが開口214aに圧入されることにより、複数の発光部3aが開口214aに沿って固定部21aに取り付けられる。これにより、LED照明装置1aを製造する際に、複数の発光部3aを固定部21aに(ほぼ任意の)所望の間隔にて容易に固定することができる。   As described above, in the LED lighting device 1a of FIG. 6, the intermittent linear opening 214a having a constant width is formed in the fixing portion 21a, and the pin 35a which is a protrusion provided in each light emitting portion 3a is press-fitted into the opening 214a. Thus, the plurality of light emitting portions 3a are attached to the fixing portion 21a along the opening 214a. Thereby, when manufacturing the LED illuminating device 1a, the some light emission part 3a can be easily fixed to the fixing | fixed part 21a by the (nearly arbitrary) desired space | interval.

LED照明装置は、様々な変形が可能である。 Upper Symbol LED lighting device, various modifications are possible.

図1のLED照明装置1では、発光部3が着脱自在に固定部21に固定されるため、導電線39,39aを比較的長くすることにより、工場や室内等へのLED照明装置の設置後において、複数の発光部3の間隔が、可能な範囲で任意に変更されてもよい。この場合に、図8に示すように、長手方向の一部の範囲において発光部3を密に配列することにより、当該範囲近傍における光の強度を増大することができる。このようなLED照明装置1では、展示物の照明等を行う際に、展示物の配置に合わせて光の強度分布をある程度任意に変更することが可能である。なお、図8のLED照明装置1では、密に隣接する2つの発光部3間における導電線39がY方向に束ねられて、溝213内に挿入される。   In the LED lighting device 1 of FIG. 1, since the light emitting unit 3 is detachably fixed to the fixing unit 21, the conductive wires 39 and 39a are made relatively long so that the LED lighting device is installed in a factory or a room. In this case, the intervals between the plurality of light emitting units 3 may be arbitrarily changed within a possible range. In this case, as shown in FIG. 8, the light intensity in the vicinity of the range can be increased by densely arranging the light emitting units 3 in a partial range in the longitudinal direction. In such an LED lighting device 1, it is possible to arbitrarily change the light intensity distribution to some extent according to the arrangement of the exhibit when performing illumination of the exhibit or the like. In the LED lighting device 1 of FIG. 8, the conductive wires 39 between two light emitting units 3 that are closely adjacent to each other are bundled in the Y direction and inserted into the groove 213.

図1および図6のLED照明装置1,1aでは、雄ねじ35またはピン35aを基板31に形成された貫通孔34を介して開口214,214aに挿入することにより、発光部3,3aが固定部21,21aに固定されるが、雄ねじ状に形成された突起部、または、突起状の突起部が発光部に固定され、または、発光部と一体的に形成され、当該突起部を開口214,214aに挿入することにより、発光部が固定部21,21aに固定されてもよい。すなわち、LED照明装置では、複数の発光部のそれぞれに設けられる突起状または雄ねじ状の突起部(雄ねじ35、および、ピン35aを含む。)が開口に圧入または螺合されることにより、複数の発光部のそれぞれが固定部に固定される。   In the LED lighting devices 1 and 1a of FIGS. 1 and 6, the light emitting units 3 and 3a are fixed by inserting the male screw 35 or the pin 35a into the openings 214 and 214a through the through holes 34 formed in the substrate 31. 21 and 21a are fixed to the light emitting part, or are formed integrally with the light emitting part, and the protrusions are formed in the openings 214, 21a. The light emitting part may be fixed to the fixing parts 21 and 21a by being inserted into 214a. That is, in the LED lighting device, a plurality of protrusions or male screw-like protrusions (including the male screw 35 and the pin 35a) provided in each of the plurality of light emitting parts are press-fitted or screwed into the opening, thereby Each of the light emitting units is fixed to the fixing unit.

上記LED照明装置1,1aでは、同様の形状である2つの開口が固定部に互いに平行に形成され、当該2つの開口にそれぞれ螺合または圧入される2つの突起部が各発光部に設けられることにより、発光部が固定部に強固に固定されるが、連続する一定幅の直線状、または、断続する一定幅の直線状の1つの開口のみが固定部に形成され、各発光部に設けられる1以上の突起部が当該開口に螺合または圧入されることにより、発光部が固定部に固定されてもよい。また、3以上の開口が幅方向に並んで形成され、各発光部が突起部により任意の開口に締結されることにより、複数の発光部の位置がX方向に相違してもよい。   In the LED lighting devices 1 and 1a, two openings having the same shape are formed in parallel to the fixed portion, and two protrusions that are screwed or press-fitted into the two openings are provided in each light emitting portion. As a result, the light emitting part is firmly fixed to the fixed part, but only one continuous opening having a constant width or a continuous straight line having a constant width is formed in the fixed part. The light emitting part may be fixed to the fixing part by screwing or press-fitting one or more protruding parts into the opening. Further, three or more openings may be formed side by side in the width direction, and each light emitting part may be fastened to an arbitrary opening by a protrusion, whereby the positions of the plurality of light emitting parts may be different in the X direction.

連続または断続する一定幅の開口は、曲線状(例えば、1/4円弧状)に形成されてもよい。すなわち、固定部における開口は、連続する一定幅の線状、または、断続する一定幅の線状に形成されていればよい。   The continuous or intermittent opening having a constant width may be formed in a curved shape (for example, a 1/4 arc shape). In other words, the opening in the fixed portion only needs to be formed in a continuous linear shape having a constant width or an intermittent constant width.

上記実施の形態では、発光部の固定部、拡散パネルの保持部、反射板、および、筐体としての役割を果たす本体部2,2aが、押し出し成形により一体的に、すなわち、連続する1つの部材として形成されるが、LED照明装置の設計によっては、本体部は押し出し成形以外の他の手法(例えば、板金加工や溶接)にて作製されてもよく、また、固定部、反射板、筐体等が個別の部材として形成されてもよい。   In the above embodiment, the light emitting part fixing part, the diffusion panel holding part, the reflecting plate, and the main body parts 2 and 2a serving as a housing are integrally formed by extrusion, that is, one continuous part. Although it is formed as a member, depending on the design of the LED lighting device, the main body portion may be manufactured by a technique other than extrusion (for example, sheet metal processing or welding). A body or the like may be formed as an individual member.

隣接する2つの発光部間の導電線39は、必ずしもおよそ全体が開口214,214a内に配置される必要ななく、導電線39の少なくとも一部が、当該2つの発光部の間において開口214,214aに挿入されることにより、2つの発光部間にて導電線39の大部分が過度に浮き上がって(設置した状態では垂れ下がって)大きな影となることを防止することができる。   The conductive line 39 between two adjacent light emitting units does not necessarily have to be disposed entirely in the openings 214 and 214a, and at least a part of the conductive line 39 is provided between the two light emitting units. By being inserted into 214 a, it is possible to prevent a large portion of the conductive wire 39 from floating excessively between the two light emitting portions (hanging down in the installed state) to form a large shadow.

LED照明装置の設置場所は工場や室内の天井に限定されず、例えば、LED照明装置が壁面に設置されてもよい。また、LED照明装置は、大型の各種装置内の照明等に用いられてもよい。   The installation place of the LED lighting device is not limited to the factory or the ceiling in the room, and for example, the LED lighting device may be installed on the wall surface. Further, the LED lighting device may be used for lighting in various large devices.

上記実施の形態および各変形例における構成は、相互に矛盾しない限り適宜組み合わせられてよい。   The configurations in the above-described embodiments and modifications may be combined as appropriate as long as they do not contradict each other.
