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Ａ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、さらに天井材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。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して、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Ａが天井に施工される。   Then, the construction procedure of the lighting fixture A is demonstrated. First, the operator passes the power line exposed to the indoor side through the hole 111a provided in the instrument body 1, and further passes the suspension bolt 200 exposed to the indoor side through the ceiling material 100 through the hole 111b. A nut 300 is screwed into the bolt 200 to fix the instrument body 1 to the ceiling material 100. After that, the operator connects the power line to the terminal block 251, and at least the power supply device 24 and the terminal block block 25 are accommodated in the accommodating recess 11, for example, provided on the instrument body 1 and the attachment member 21, respectively. The light source unit 2 is attached to the instrument body 1 by a fitting structure (not shown). The lighting fixture A is constructed on the ceiling according to the above procedure.

図７（ａ）〜図７（ｃ）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６（ａ）〜図６（ｃ）では、電源装置２４を取付部材２１の両側面部２１２，２１２に取り付けたが、本例では、電源装置２４を片方の側面部２１２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。つまり、作業者が、取付部材２１の側面部２１２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に配置し、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。   FIG. 7A to FIG. 7C show another example in which the power supply device 24 is attached to the attachment member 21. In FIG. 6A to FIG. 6C, the power supply device 24 is attached to the both side surfaces 212 and 212 of the attachment member 21, but in this example, the power supply device 24 is attached only to one side surface portion 212. 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. . That is, the operator holds the power supply device 24 in a state where the position of each locking claw 212b provided on the side surface portion 212 of the attachment member 21 matches the position of the opening 242g provided on each attachment piece 242f of the power supply device 24. The power supply device 24 is attached to the attachment member 21 when it is disposed in the accommodating portion 213 of the attachment member 21 and all the locking claws 212b are bent inward through the opening 242g.

而して本実施形態によれば、取付部材２１の側面部２１２に電源装置２４を取り付けているので、底面部２１１の中央部に電源装置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。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２１２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Ａへの送り電線などを通すための配線スペースとして溝部２４２ｅを利用することで、配線スペースを別に設けなくてもよく、コストアップを抑えることができる。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２１２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。   Thus, according to the present embodiment, since the power supply device 24 is attached to the side surface portion 212 of the attachment member 21, a larger space is ensured as compared with the case where the power supply device 24 is attached to the central portion of the bottom surface portion 211. Can do. 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. Further, when the storage case 242 is attached to the side surface portion 212 so as not to contact the bottom surface portion 211 of the attachment member 21 as in this embodiment, the heat transfer from the LED board 22 to the power supply device 24 and the power supply device 24 are performed. Heat transfer to the LED substrate 22 can be suppressed. Furthermore, by using the groove portion 242e as a wiring space for passing an electric wire from the terminal block 25 to the power supply device 24, an electric wire from the power supply device 24 to the LED board 22, a feed electric wire to the adjacent lighting fixture A, and the like. Further, it is not necessary to provide a separate wiring space, and the cost increase can be suppressed. 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 212, 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.
