　端子台ブロック２５は、矩形箱状に形成された端子台２５１と、端子台２５１を取付部材２１に取り付けるための取付金具２５２とを有する。端子台２５１には、天井材１００を通して室内側（下側）に露出する電源線（図示せず）が接続されるとともに、電源装置２４との間を電気的に接続する電線（図示せず）が接続される。そして、この端子台ブロック２５は、少なくとも一部が収容部２１３に収容された状態で、例えばねじなどを用いて取付部材２１に取り付けられる。 The terminal block 25 has a terminal block 251 formed in a rectangular box shape and a mounting bracket 252 for mounting the terminal block 251 to the mounting member 21. A power line (not shown) exposed to the indoor side (lower side) through the ceiling member 100 is connected to the terminal block 251, and an electric wire (not shown) that electrically connects the power source 24. Is connected. And this terminal block block 25 is attached to the attachment member 21 using a screw etc. in the state in which at least one part was accommodated in the accommodating part 213, for example.
　ここで、図５Ａ～図６Ｃは電源装置２４を取付部材２１に取り付けた状態の一例を示しており、以下に取付手順について説明する。まず最初に、作業者は、収納部２４２ａの開口側を取付部材２１側に向けた状態で電源装置２４を取付部材２１の収容部２１３に配置する。このとき、作業者は、取付部材２１の各側面部２１２ｃ，２１２ｄに設けた係止爪２１２ｂの位置と、電源装置２４の各取付片２４２ｆ及び第２延出部２４２ｃに設けた開口部２４２ｇの位置をそれぞれ合わせる。 Here, FIGS. 5A to 6C show an example of a state in which the power supply device 24 is attached to the attachment member 21, and the attachment procedure will be described below. First, the worker arranges the power supply device 24 in the housing portion 213 of the mounting member 21 with the opening side of the housing portion 242a facing the mounting member 21 side. At this time, the operator can adjust the positions of the locking claws 212b provided on the side surfaces 212c and 212d of the attachment member 21, and the openings 242g provided on the attachment pieces 242f and the second extension 242c of the power supply device 24. Adjust the position.
　そして、作業者が、すべての係止爪２１２ｂを開口部２４２ｇを通して内側に折り曲げると、各係止爪２１２ｂがそれぞれ対応する開口部２４２ｇの開口端縁に引っ掛かり、電源装置２４が取付部材２１に取り付けられる。このように、電源装置２４を両側面部２１２ｃ，２１２ｄに取り付けた場合には、取付部材２１に対して電源装置２４を強固に取り付けることができる。 Then, when the operator bends all the locking claws 212b inward through the openings 242g, each locking claw 212b is caught on the opening edge of the corresponding opening 242g, and the power supply device 24 is attached to the mounting member 21. It is done. As described above, when the power supply device 24 is attached to the both side surfaces 212c and 212d, the power supply device 24 can be firmly attached to the attachment member 21.
　次に、光源ユニット２の組立手順について説明する。まず最初に、作業者は、電源装置２４及び端子台ブロック２５をそれぞれ取付部材２１の上面側に取り付け、さらに電源装置２４と端子台ブロック２５の間を電線により接続する。その後、作業者は、係止爪２１１ｃによりＬＥＤ基板２２を取付部材２１の底面部２１１に固定し、ＬＥＤ基板２２のコネクタ２２３から導出する電線を取付部材２１の底面部２１１に設けた孔２１１ａに通した後、その端部を電源装置２４に接続する。 Next, the assembly procedure of the light source unit 2 will be described. First, the operator attaches the power supply device 24 and the terminal block block 25 to the upper surface side of the attachment member 21, respectively, and further connects the power supply device 24 and the terminal block block 25 with electric wires. Thereafter, the operator fixes the LED substrate 22 to the bottom surface portion 211 of the mounting member 21 with the locking claws 211c, and the electric wire led out from the connector 223 of the LED substrate 22 into the hole 211a provided in the bottom surface portion 211 of the mounting member 21. After passing, the end is connected to the power supply device 24.
　そして最後に、作業者は、開口側を上向きにした状態でカバー部材２３を取付部材２１に組み付ける。このとき、カバー部材２３の各突壁部２３３にそれぞれ設けた突起部２３３ａが、取付部材２１の各側面部２１２ｃ，２１２ｄにそれぞれ設けた傾斜部２１２ａに引っ掛かり、カバー部材２３が取付部材２１に取り付けられる。以上のような手順に従って、光源ユニット２が組み立てられる。なお、カバー部材２３を取付部材２１に取り付ける上記方法は一例であり、他の方法であってもよい。 Finally, the operator attaches the cover member 23 to the mounting member 21 with the opening side facing upward. At this time, the protrusions 233 a provided on the respective protruding wall portions 233 of the cover member 23 are hooked on the inclined portions 212 a provided on the respective side surfaces 212 c and 212 d of the attachment member 21, and the cover member 23 is attached to the attachment member 21. It is done. The light source unit 2 is assembled according to the above procedure. In addition, the said method of attaching the cover member 23 to the attachment member 21 is an example, and another method may be sufficient.
　続けて、照明器具１０の施工手順について説明する。まず最初に、作業者は、室内側に露出する上記電源線を器具本体１に設けた孔１１１ａに通し、天井材１００を通して室内側に露出する吊ボルト２００を孔１１１ｂに通した後、吊ボルト２００にナット３００をねじ込んで器具本体１を天井材１００に固定する。 Next, the construction procedure of the lighting fixture 10 will be described. First, the operator passes the power line exposed to the indoor side through the hole 111a provided in the instrument main body 1, passes the suspension bolt 200 exposed to the indoor side through the ceiling material 100, and then passes through the hole 111b. A nut 300 is screwed into 200 to fix the instrument body 1 to the ceiling material 100.
　その後、作業者は、上記電源線を端子台２５１に接続し、少なくとも電源装置２４及び端子台ブロック２５が収容凹部１１に収容されるように、例えば器具本体１及び取付部材２１にそれぞれ設けた嵌合構造（図示せず）により光源ユニット２を器具本体１に取り付ける。以上のような手順に従って、照明器具１０が天井に施工される。 After that, the operator connects the power line to the terminal block 251, and fits provided in, for example, the instrument body 1 and the attachment member 21 so that at least the power supply device 24 and the terminal block block 25 are accommodated in the accommodating recess 11. The light source unit 2 is attached to the instrument body 1 by a combined structure (not shown). The lighting fixture 10 is constructed on the ceiling according to the above procedure.
　図７Ａ～図７Ｃは電源装置２４を取付部材２１に取り付けた状態の別の例を示している。図６Ａ～図６Ｃでは、電源装置２４を取付部材２１の両側面部２１２ｃ，２１２ｄに取り付けたが、本例では、電源装置２４を片方の側面部２１２ｃのみに取り付けている。本例の電源装置２４には、第１延出部２４２ｂ及び第２延出部２４２ｃが設けられておらず、収納部２４２ａに一体に設けられた取付片２４２ｆ，２４２ｆにより取付部材２１に取り付けられる。 7A to 7C show another example of the state where the power supply device 24 is attached to the attachment member 21. FIG. 6A to 6C, the power supply device 24 is attached to both side portions 212c and 212d of the attachment member 21, but in this example, the power supply device 24 is attached only to one side portion 212c. The power supply device 24 of this example is not provided with the first extension portion 242b and the second extension portion 242c, and is attached to the attachment member 21 by attachment pieces 242f and 242f provided integrally with the storage portion 242a. .
　つまり、作業者が、取付部材２１の側面部２１２ｃに設けた各係止爪２１２ｂの位置と、電源装置２４の各取付片２４２ｆに設けた開口部２４２ｇの位置を合わせた状態で電源装置２４を取付部材２１の収容部２１３に配置する。そして、作業者が、すべての係止爪２１２ｂを開口部２４２ｇを通して内側に折り曲げると、電源装置２４が取付部材２１に取り付けられる。 That is, the operator holds the power supply device 24 in a state in which the position of each locking claw 212b provided on the side surface portion 212c of the attachment member 21 matches the position of the opening 242g provided on each attachment piece 242f of the power supply device 24. It arrange | positions in the accommodating part 213 of the attachment member 21. FIG. And if an operator bend | folds all the latching claws 212b inside through the opening part 242g, the power supply device 24 will be attached to the attachment member 21. FIG.
　而して、本実施形態によれば、取付部材２１の側面部２１２ｃに電源装置２４を取り付けているので、底面部２１１の幅方向における中央に電源装置２４を取り付けた場合に比べて大きなスペースを確保することができる。これにより、比較的大きい電線や電気機能部品などを上記スペースに配置することができることから、電線や電気機能部品の配置の自由度を高めることができる。 Thus, according to the present embodiment, since the power supply device 24 is attached to the side surface portion 212c of the attachment member 21, a larger space is required than when the power supply device 24 is attached to the center in the width direction of the bottom surface portion 211. Can be secured. Thereby, since a comparatively big electric wire, an electric functional component, etc. can be arrange | positioned in the said space, the freedom degree of arrangement | positioning of an electric wire or an electric functional component can be raised.
　また、本実施形態のように、取付部材２１の底面部２１１に接触しないようにして収納ケース２４２を側面部２１２ｃに取り付けた場合には、ＬＥＤ基板２２から電源装置２４への熱移動及び電源装置２４からＬＥＤ基板２２への熱移動を抑えることができる。さらに、端子台ブロック２５から電源装置２４への電線や、電源装置２４からＬＥＤ基板２２への電線、隣接する照明器具１０へ電力を送る電線などを溝部２４２ｅに配線することで、配線スペースを別に設けなくてもよく、コストアップが抑えられる。 Further, as in the present embodiment, when the storage case 242 is attached to the side surface portion 212c so as not to contact the bottom surface portion 211 of the attachment member 21, heat transfer from the LED board 22 to the power supply device 24 and the power supply device The heat transfer from 24 to the LED substrate 22 can be suppressed. Further, by wiring the wire from the terminal block block 25 to the power supply device 24, the wire from the power supply device 24 to the LED substrate 22, the electric wire that sends power to the adjacent lighting fixture 10, etc. in the groove 242 e, the wiring space can be separated. There is no need to provide it, and the cost increase can be suppressed.
　また、例えば取付ねじを用いてＬＥＤ基板２２を底面部２１１に取り付けた場合、電源装置２４を底面部２１１に取り付けようとすると、取付部材２１の長手方向において上記取付ねじと干渉しない位置に取り付けなければならず、取り付けの自由度は低い。これに対して、電源装置２４を側面部２１２ｃに取り付けた場合には、取付部材２１の長手方向において上記取付ねじと干渉する位置であっても取り付けることができ、取り付けの自由度を高めることができる。 Further, for example, when the LED board 22 is attached to the bottom surface portion 211 using an attachment screw, if the power supply device 24 is to be attached to the bottom surface portion 211, it must be attached at a position that does not interfere with the attachment screw in the longitudinal direction of the attachment member 21. Therefore, the degree of freedom of installation is low. On the other hand, when the power supply device 24 is attached to the side surface portion 212c, it can be attached even at a position that interferes with the attachment screw in the longitudinal direction of the attachment member 21, and the degree of freedom of attachment can be increased. it can.
　図８Ａは本実施形態の別の照明器具１０の断面図であり、図８Ｂは本実施形態の別の照明器具１０に用いられる光源ユニット２の断面図である。図４Ａの照明器具１０は、天井材１００に取り付けられる天井直付け型の照明器具であるが、照明器具１０は、図８Ａに示すように、天井材１００に設けた埋込孔１００ａを通して天井裏に設置される天井埋込型の照明器具であってもよい。 8A is a cross-sectional view of another lighting fixture 10 of the present embodiment, and FIG. 8B is a cross-sectional view of a light source unit 2 used in another lighting fixture 10 of the present embodiment. The lighting fixture 10 in FIG. 4A is a ceiling-mounted lighting fixture that is attached to the ceiling material 100. However, the lighting fixture 10 is connected to the ceiling through an embedded hole 100a provided in the ceiling material 100 as shown in FIG. 8A. It may be a ceiling-embedded lighting fixture installed on the ceiling.
　本例の照明器具１０は、吊ボルト（図示せず）を用いて天井裏に設置される支持部材４と、支持部材４に取り付けられる反射板５と、反射板５に対して着脱自在に取り付けられる光源ユニット２とを備える。なお、光源ユニット２については図４Ｂの光源ユニット２と同様であり、ここでは説明を省略する。 The lighting fixture 10 of this example is detachably attached to the support member 4 installed on the back of the ceiling using a suspension bolt (not shown), the reflection plate 5 attached to the support member 4, and the reflection plate 5. The light source unit 2 is provided. The light source unit 2 is the same as the light source unit 2 shown in FIG. 4B, and the description thereof is omitted here.
　反射板５は、板金に曲げ加工を施すことで長尺且つ下面が開口する扁平な箱状に形成され、反射板５の底面部には、光源ユニット２を収容するための矩形の収容凹部５１が反射板５の全長に亘って設けられている。また、反射板５の開口端縁には、側方に延出する鍔部５２が全周に亘って設けられており、天井裏に設置された支持部材４に反射板５を取り付けた状態では、鍔部５２が天井材１００の下面に接している（図８Ａ参照）。ここに本例では、反射板５により器具本体が構成されている。 The reflector 5 is formed in a flat box shape that is long and has an open bottom by bending the sheet metal, and a rectangular housing recess 51 for housing the light source unit 2 is formed on the bottom surface of the reflector 5. Is provided over the entire length of the reflector 5. Moreover, the opening edge of the reflecting plate 5 is provided with a flange 52 extending over the entire circumference, and when the reflecting plate 5 is attached to the support member 4 installed on the back of the ceiling. The flange 52 is in contact with the lower surface of the ceiling material 100 (see FIG. 8A). Here, in the present example, the reflector main body is constituted by the reflecting plate 5.
　次に、本実施形態の別の照明器具１０の施工手順について説明する。まず最初に、作業者は、天井材１００に設けた埋込孔１００ａを通して支持部材４を天井裏に配置し、天井裏に設けた吊ボルト（図示せず）に支持部材４を取り付ける。その後、作業者は、天井裏に配線された電源線（図示せず）を反射板５の収容凹部５１に設けた孔（図示せず）を通して室内側（下側）に引き出し、例えばねじなどを用いて反射板５を支持部材４に取り付ける。 Next, the construction procedure of another lighting apparatus 10 of this embodiment will be described. First, the operator places the support member 4 on the back of the ceiling through the embedded hole 100a provided in the ceiling material 100, and attaches the support member 4 to a suspension bolt (not shown) provided on the back of the ceiling. Thereafter, the operator pulls out a power line (not shown) wired on the back of the ceiling to the indoor side (lower side) through a hole (not shown) provided in the housing recess 51 of the reflecting plate 5, for example, a screw or the like. The reflecting plate 5 is attached to the support member 4 by using it.
　そして、作業者は、上記電源線を端子台ブロック（図示せず）に接続し、少なくとも電源装置２４及び端子台ブロックが収容凹部５１に収容されるように、例えば反射板５及び取付部材２１にそれぞれ設けた嵌合構造（図示せず）により光源ユニット２を反射板５に取り付ける。以上のような手順に従って、照明器具１０が天井裏に設置される。 Then, the operator connects the power line to a terminal block (not shown) and, for example, attaches to the reflecting plate 5 and the mounting member 21 so that at least the power supply device 24 and the terminal block are accommodated in the accommodating recess 51. The light source unit 2 is attached to the reflecting plate 5 by a fitting structure (not shown) provided. The lighting fixture 10 is installed behind the ceiling according to the above procedure.
　而して、本例においても、図５Ａ～図７Ｃに示した取付部材２１を用いて、電源装置２４を取付部材２１の側面部２１２ｃに取り付けた場合には、底面部２１１の幅方向における中央に電源装置２４を取り付けた場合に比べて大きなスペースを確保することができる。これにより、比較的大きい電線や電気機能部品などを上記スペースに配置することができることから、電線や電気機能部品の配置の自由度を高めることができる。 Thus, also in this example, when the power supply device 24 is attached to the side surface portion 212c of the attachment member 21 using the attachment member 21 shown in FIGS. 5A to 7C, the center in the width direction of the bottom surface portion 211 is used. A large space can be ensured as compared with the case where the power supply device 24 is attached to. Thereby, since a comparatively big electric wire, an electric functional component, etc. can be arrange | positioned in the said space, the freedom degree of arrangement | positioning of an electric wire or an electric functional component can be raised.
　なお、図７Ａ～図７Ｃに示すように、電源装置２４を片方の側面部２１２ｃのみに取り付けた場合でも反対側に溝部を設けてもよい。また、溝部の形状についても一例であり、電線や電気機能部品などが収納できるようになっていれば他の形状でもよい。さらに、本実施形態では、取付部材２１の底面部２１１に接触しないようにして電源装置２４の収納ケース２４２を側面部２１２ｃに取り付けているが、熱の影響がない場合には底面部２１１に接触するようにして収納ケース２４２を側面部２１２ｃに取り付けてもよい。 7A to 7C, a groove portion may be provided on the opposite side even when the power supply device 24 is attached only to one side surface portion 212c. Further, the shape of the groove is also an example, and other shapes may be used as long as an electric wire, an electrical functional component, or the like can be accommodated. Furthermore, in this embodiment, the storage case 242 of the power supply device 24 is attached to the side surface portion 212c so as not to contact the bottom surface portion 211 of the attachment member 21, but when there is no influence of heat, it contacts the bottom surface portion 211.
