続いて、光源部44と結合された一対の絶縁部材43が放熱部材42の主片42aに取り付けられる。このとき、絶縁部材43に設けられた係止爪43gが、放熱部材42の側片42bに設けられた係止孔42fに挿入係止されることで、絶縁部材43が放熱部材42に対して抜け止めされる。そして、取付金具46によってレセプタクルコネクタ47が取り付けられた取付部材41が、かしめやねじなどの適当な方法によって放熱部材42に固定される。最後に、底面部45aを光源部44に対向させる向きでカバー45が放熱部材42に被せられると、側壁部45bの係合凹部45cに側片42bの係合突起42dが係合して、カバー45が放熱部材42に結合されることで光源ユニット4の組み立てが完了する。   Subsequently, a pair of insulating members 43 coupled to the light source unit 44 are attached to the main piece 42 a of the heat radiating member 42. At this time, the locking claw 43g provided on the insulating member 43 is inserted and locked into the locking hole 42f provided on the side piece 42b of the heat radiating member 42, so that the insulating member 43 is attached to the heat radiating member 42. It is prevented from coming off. Then, the mounting member 41 to which the receptacle connector 47 is mounted by the mounting bracket 46 is fixed to the heat radiating member 42 by an appropriate method such as caulking or screws. Finally, when the cover 45 is placed on the heat radiating member 42 in such a direction that the bottom surface portion 45a faces the light source portion 44, the engagement protrusion 42d of the side piece 42b engages with the engagement recess 45c of the side wall portion 45b. The assembly of the light source unit 4 is completed by coupling 45 to the heat radiating member 42.

さらに、照明器具Aの施工手順について、図2及び図3を参照しながら説明する。組み立てられた光源ユニット4は、取付金具46及びレセプタブルコネクタ47を前面カバー3の収納凹部32の底部に設けられた開口部(図示せず)を通して上側(収納凹部32と反対側)に配置した状態で、ねじなどの適当な方法によって前面カバー3に取り付けられる。なお本実施形態では、図1に示すように、前面カバー3に対して2個の光源ユニット4,4が横並びに取り付けられる。また、前面カバー3の長手方向における両端に設けられた各ねじ挿通孔33に挿通させた取付ねじ7を対応する取付金具2のねじ孔(図示せず)にねじ込むことで、取付金具2,2が前面カバー3に取り付けられる。   Furthermore, the construction procedure of the lighting fixture A will be described with reference to FIGS. In the assembled light source unit 4, the mounting bracket 46 and the receptible connector 47 are arranged on the upper side (opposite to the storage recess 32) through an opening (not shown) provided at the bottom of the storage recess 32 of the front cover 3. In the state, it is attached to the front cover 3 by an appropriate method such as a screw. In the present embodiment, as shown in FIG. 1, two light source units 4 and 4 are attached side by side to the front cover 3. Further, by attaching the mounting screws 7 inserted into the screw insertion holes 33 provided at both ends in the longitudinal direction of the front cover 3 into the corresponding screw holes (not shown) of the mounting bracket 2, the mounting brackets 2, 2 are provided. Is attached to the front cover 3.

そして、各ボス部13のねじ挿通孔に挿通させた取付ボルト(図示せず)を用いて器具本体1を天井面100に固定した後、各プラグコネクタ5を対応するレセプタクルコネクタ47に接続するとともに、各取付金具2の係止爪23,23を器具本体1の対応する係止孔14,14にそれぞれ係止させることで、取付金具2,2を介して前面カバー3及び光源ユニット4,4が器具本体1に取り付けられ、照明器具Aの施工が完了する(図1及び図4参照)。   And after fixing the instrument main body 1 to the ceiling surface 100 using the attachment bolt (not shown) penetrated to the screw insertion hole of each boss | hub part 13, while connecting each plug connector 5 to the corresponding receptacle connector 47, it is. The locking claws 23 and 23 of the mounting brackets 2 are locked in the corresponding locking holes 14 and 14 of the instrument body 1, respectively, so that the front cover 3 and the light source units 4 and 4 are mounted via the mounting brackets 2 and 2. Is attached to the fixture body 1, and the construction of the lighting fixture A is completed (see FIGS. 1 and 4).

ここで、図1は照明器具Aを天井面100に取り付けた状態の断面図である。光源部44の光軸P1に対する前面カバー3の反射部34の傾斜角度はθ1であり、また光源部44の光軸P1に対する反射部43bの傾斜角度はθ2(θ2>θ1)である。つまり本実施形態では、内側に配置される反射部43bの傾斜角度を外側に配置される反射部34の傾斜角度よりも大きくすることで広角な配光を実現し、また外側に配置される反射部34の傾斜角度を小さくすることで、器具全体の幅寸法を小さくすることができて照明器具Aの小型化が図れる。   Here, FIG. 1 is a cross-sectional view of the state in which the lighting fixture A is attached to the ceiling surface 100. The inclination angle of the reflection part 34 of the front cover 3 with respect to the optical axis P1 of the light source part 44 is θ1, and the inclination angle of the reflection part 43b with respect to the optical axis P1 of the light source part 44 is θ2 (θ2> θ1). That is, in this embodiment, wide angle light distribution is realized by making the inclination angle of the reflection part 43b arranged on the inside larger than the inclination angle of the reflection part 34 arranged on the outside, and the reflection arranged on the outside. By reducing the inclination angle of the portion 34, the overall width of the fixture can be reduced, and the lighting fixture A can be reduced in size.

また図1中の二点鎖線は、カバー45の底面部45aに沿って延長された曲面bを示しており、本実施形態では、この曲面bに対して光源ユニット4に近い側に前面カバー3の平坦面35が位置している。そして、カバー45と平坦面35がこのような位置関係にあることで、カバー45で拡散させた光を平坦面35に向けて照射することができる。   1 indicates a curved surface b extending along the bottom surface 45a of the cover 45. In the present embodiment, the front cover 3 is closer to the light source unit 4 than the curved surface b. The flat surface 35 is located. Since the cover 45 and the flat surface 35 are in such a positional relationship, the light diffused by the cover 45 can be emitted toward the flat surface 35.

而して本実施形態によれば、光源ユニット4から照射された光を反射部34及び反射部43bで反射させることで照明空間への照射光量を確保することができ、しかもカバー45で拡散させた光を平坦面35に向けて照射できることから、平坦面35が暗くなることがなく光むらを低減することができる。   Thus, according to the present embodiment, the light emitted from the light source unit 4 is reflected by the reflecting portion 34 and the reflecting portion 43b, so that the amount of light irradiated to the illumination space can be secured and diffused by the cover 45. Therefore, the unevenness of light can be reduced without the flat surface 35 becoming dark.

なお本実施形態では、光源ユニット4を2列に配置した長方形タイプの照明器具Aを例に説明したが、例えば光源ユニット4を4列や8列に配置したスクエアタイプの照明器具であってもよく、本実施形態に限定されない。また本実施形態では、発光ダイオードを光源としているが、光源は発光ダイオードに限定されるものではなく、蛍光灯などであってもよい。さらに、光源ユニット4の個数は本実施形態に限定されるものではなく、1個でもいいし、3個以上であってもよい。   In this embodiment, the rectangular type lighting fixture A in which the light source units 4 are arranged in two rows has been described as an example. However, for example, a square type lighting fixture in which the light source units 4 are arranged in four rows or eight rows may be used. Well, it is not limited to this embodiment. In this embodiment, the light emitting diode is used as the light source, but the light source is not limited to the light emitting diode, and may be a fluorescent lamp or the like. Furthermore, the number of the light source units 4 is not limited to this embodiment, and may be one or three or more.
