次に、本実施形態に係る照明器具Aの組立手順を説明する。ただし、以下に説明する組立手順は一例であり、いくつかの手順が入れ替えられても構わない。なお、器具本体2には、先に支持部材4が取り付けられていることが好ましい。   Next, the assembly procedure of the lighting fixture A according to this embodiment will be described. However, the assembly procedure described below is an example, and some procedures may be replaced. In addition, it is preferable that the support member 4 is attached to the instrument body 2 first.

まず、組立作業の作業者は、放熱ブロック11のベース部110に2つのLEDモジュール10をねじ止めして取り付ける。また、作業者は、2つのLEDモジュール10のそれぞれの速結端子台102に電気ケーブルの電線65(の導体)をそれぞれ電気的に接続する。続いて、作業者は、放熱ブロック11のベース部110に防水パッキン13を装着する。つまり、図4に示すように、作業者は、防水パッキン13の凹所130にベース部110を全周に渡って嵌め込めばよい。そして、作業者は、防水パッキン13の外周面に形成されている溝131に、器具本体2の上側壁200及び下側壁201の後端から第1〜第4窓孔204〜207の方へ突出する部分を挿入する(図4参照)。さらに、作業者は、防水パッキン13の後端側の溝132に、押さえ金具14の押さえ片140を差し込み、押さえ金具14の固定片141のねじ挿通孔1410に挿通したねじを器具本体2の第1固定部21にねじ込む。その結果、ベース部110は、防水パッキン13を介して、器具本体2の枠部20及び仕切壁(第1仕切壁22A、第2仕切壁22B)と押さえ金具14の押さえ片140とに挟み込まれ、器具本体2に固定される(図4参照)。さらに、作業者は、速結端子台102に接続されている電気ケーブルの電線65を、上側壁200のケーブル挿通孔2001及び下側壁201のケーブル挿通孔に挿通して枠部20の外にそれぞれ引き出す。このとき、作業者は、第1窓孔204及び第2窓孔205の位置に取り付けられた2つの光源ユニット1の電気ケーブルを、上側壁200のケーブル挿通孔2001に挿通して枠部20の外に引き出す。一方、作業者は、第3窓孔206及び第4窓孔207の位置に取り付けられた2つの光源ユニット1の電気ケーブルを、下側壁201のケーブル挿通孔に挿通して枠部20の外に引き出す。なお、2つの速結端子台102は、実装基板101の長手方向に対して傾くように実装されている。そのため、作業者は、それぞれのLEDモジュール10の1つの速結端子台102に差し込み接続する電線65をケーブル挿通孔2001に挿通するに当たり、電線65を急激に曲げずに緩やかに曲げればよい。その結果、電線65や速結端子台102に加わる力を抑えることができる。   First, the worker of the assembly work attaches the two LED modules 10 to the base portion 110 of the heat dissipation block 11 by screwing. In addition, the worker electrically connects the electric wire 65 (conductor) of the electric cable to the quick connection terminal block 102 of each of the two LED modules 10. Subsequently, the worker attaches the waterproof packing 13 to the base portion 110 of the heat dissipation block 11. That is, as shown in FIG. 4, the operator may fit the base portion 110 in the recess 130 of the waterproof packing 13 over the entire circumference. And an operator protrudes in the groove | channel 131 formed in the outer peripheral surface of the waterproof packing 13 toward the 1st-4th window holes 204-207 from the rear end of the upper wall 200 of the instrument main body 2, and the lower wall 201. The part to be inserted is inserted (see FIG. 4). Further, the operator inserts the holding piece 140 of the holding fitting 14 into the groove 132 on the rear end side of the waterproof packing 13, and inserts the screw inserted into the screw insertion hole 1410 of the fixing piece 141 of the holding fitting 14 into the first part of the instrument main body 2. 1 Screw into the fixed part 21. As a result, the base portion 110 is sandwiched between the frame portion 20 and the partition wall (first partition wall 22A, second partition wall 22B) of the instrument body 2 and the pressing piece 140 of the pressing metal member 14 via the waterproof packing 13. It is fixed to the instrument body 2 (see FIG. 4). Further, the operator inserts the electric wire 65 of the electric cable connected to the quick connection terminal block 102 into the cable insertion hole 2001 of the upper side wall 200 and the cable insertion hole of the lower side wall 201 and out of the frame part 20. Pull out. At this time, the operator inserts the electric cables of the two light source units 1 attached to the positions of the first window hole 204 and the second window hole 205 into the cable insertion hole 2001 of the upper wall 200 and Pull out. On the other hand, the operator inserts the electric cables of the two light source units 1 attached at the positions of the third window hole 206 and the fourth window hole 207 into the cable insertion hole of the lower side wall 201 and out of the frame part 20. Pull out. The two quick connection terminal blocks 102 are mounted so as to be inclined with respect to the longitudinal direction of the mounting substrate 101. Therefore, the operator may bend the electric wire 65 gently without bending it suddenly when inserting the electric wire 65 inserted into and connected to one quick connection terminal block 102 of each LED module 10 into the cable insertion hole 2001. As a result, the force applied to the electric wire 65 and the quick connection terminal block 102 can be suppressed.

さらに、作業者は、上側壁200及び下側壁201のねじ孔2002にケーブルグランド208をねじ止めする(図9A参照)。それから、作業者は、器具本体2の第4固定部26にレンズブロック12をねじ止めする。このようにして、器具本体2への光源ユニット1の取付が完了する。   Further, the operator screws the cable gland 208 into the screw holes 2002 in the upper side wall 200 and the lower side wall 201 (see FIG. 9A).

In facilities such as stadiums, there is a limit to the space where lighting fixtures can be installed. Therefore, it is desirable that the luminaire be as small as possible. For example, if the size (length) of the protective cover 5 in the left-right direction is the same, the smaller the projection amount of the bearing portion 27 of the fixture body 2, the smaller the lighting fixture A can be achieved.

そこで、本実施形態に係る照明器具Aは、図9A及び図9Bに示すように、放熱板111と一対のアーム片41との間に、保護カバー5の第1カバー体50が配置される。さらに、本実施形態に係る照明器具Aは、ボルト43(回転軸)の軸方向(左右方向)に沿って、第1カバー体50(の切欠部502)と軸受け部27とが重なるように構成される。したがって、本実施形態に係る照明器具Aは、保護カバー5(の第1カバー体50)に対する軸受け部27の突出量が少なくなるので、小型化が可能になり、かつ、外観上の見栄えの向上を図ることができる。   Therefore, in the lighting fixture A according to the present embodiment, the first cover body 50 of the protective cover 5 is disposed between the heat radiating plate 111 and the pair of arm pieces 41, as shown in FIGS. 9A and 9B.
