It is configured so that dust and dust do not enter. The insertion hole 23 is provided on the right side of the light source unit 4 and above the reflection member 33 of the base 3.

保持部材8には、例えばケーブルグランドが使用される。保持部材8は、筒状に形成される本体81と、内周面に雌ねじを有し本体81の一端の外周面に螺合されるキャップ82と、本体81の他端側であって、内周面に雌ねじを有し、本体81を天板21に固定するためのナット83とを備える。本体81の外周面には、キャップ82に螺合可能な雄ねじと、ナット83に螺合可能な雄ねじが設けられる。保持部材8は、キャップ82が器具本体2内(天板21の下側)に配置されるように、かつ本体81の他端側が器具本体2の外側(天井裏110側)になるように器具本体2に配設される。保持部材8は、本体81の他端側が器具本体2の外側でナット83に螺合されることで、器具本体2に固定される。保持部材8は、本体81の内部に電線7を挿通させてキャップ82を本体81に螺合することで、電線7と本体81の内周面との間の隙間が狭くなるように構成される。したがって、本実施形態の照明器具1は、天井裏110と室内120とを空間的に遮断することができ、照明空間である室内120の気密性を高めることができる。   As the holding member 8, for example, a cable gland is used. The holding member 8 includes a main body 81 formed in a cylindrical shape, a cap 82 having a female screw on the inner peripheral surface, and being screwed to an outer peripheral surface at one end of the main body 81. A nut 83 for fixing the main body 81 to the top plate 21 is provided. On the outer peripheral surface of the main body 81, a male screw that can be screwed to the cap 82 and a male screw that can be screwed to the nut 83 are provided. The holding member 8 is provided so that the cap 82 is disposed inside the instrument main body 2 (below the top plate 21) and the other end of the main body 81 is outside the instrument main body 2 (the side of the ceiling 110). It is arranged on the main body 2. The holding member 8 is fixed to the instrument main body 2 by screwing the other end of the main body 81 to a nut 83 outside the instrument main body 2. The holding member 8 is configured such that the gap between the electric wire 7 and the inner peripheral surface of the main body 81 is narrowed by inserting the electric wire 7 into the main body 81 and screwing the cap 82 to the main body 81. . Therefore, the lighting fixture 1 of the present embodiment can spatially block the ceiling 110 and the room 120, and can improve the airtightness of the room 120, which is a lighting space.

そして、挿通孔23が上下方向から見て光源ユニット4の投影範囲外に設けられていることで、保持部材8もまた、光源ユニット4の投影範囲外に配設される。本実施形態の照明器具1は、上述のように構成されるので、上板311が保持部材8の下端よりも上側に配設されることが可能である。したがって、照明器具1は、保持部材8が上板311の上部に設けられる場合と比較して、薄型に形成されることが可能となる。   Since the insertion hole 23 is provided outside the projection range of the light source unit 4 when viewed from above and below, the holding member 8 is also disposed outside the projection range of the light source unit 4. Since the lighting fixture 1 of the present embodiment is configured as described above, the upper plate 311 can be disposed above the lower end of the holding member 8. Therefore, the lighting fixture 1 can be formed thinner than when the holding member 8 is provided above the upper plate 311.

また、挿通孔23が上下方向から見て、基台3の反射部材33の上側に設けられていることで、保持部材8は、基台3の投影範囲内に配設されている。つまり、保持部材8は、天板21と基台3の間に配設される。さらに、電線7は、天板21と基台3との間に引き回されて端子台6に接続される。本実施形態の照明器具1は、上述のように構成されるので、電線7および保持部材8がLED411からの照射を妨げない。さらに、照明器具1では、下方向(室内120側)から見て、保持部材8および電線7が基台3に隠れて見えないので、デザイン性が向上する。   Further, since the insertion hole 23 is provided above the reflecting member 33 of the base 3 when viewed from above and below, the holding member 8 is disposed within the projection range of the base 3. That is, the holding member 8 is disposed between the top plate 21 and the base 3. Further, the electric wire 7 is routed between the top plate 21 and the base 3 and connected to the terminal block 6. Since the lighting fixture 1 of the present embodiment is configured as described above, the electric wires 7 and the holding members 8 do not prevent the illumination from the LEDs 411. Furthermore, in the lighting fixture 1, since the holding member 8 and the electric wire 7 are hidden by the base 3 and cannot be seen from below (inside the room 120), the design is improved.

照明器具1の組み立て手順について図6を参照して説明する。なお、以下に説明する組み立て手順は一例であって、これに限定されない。   The procedure for assembling the lighting fixture 1 will be described with reference to FIG. Note that the assembling procedure described below is an example, and the present invention is not limited to this.

作業者は、保持部材8を器具本体2の内側からキャップ82が下方(内側)になるように挿通孔23に挿通し、器具本体2の外側にでている本体81の上側にナット83を締め付けて、保持部材8を器具本体2の天板21に固定する。次に、作業者は、天井裏110に配線された電線7を保持部材8に挿通して器具本体2の内側に引き出して、電線7を保持部材8に固定するためにキャップ82を締め付ける。そして、作業者は、天井材100に設けられた埋込孔111に天板21が天井裏110に入り込むように器具本体2を配設し、天井裏110に設けられた吊ボルト101をボルト孔20に挿通してナット102を締め付ける。   The operator inserts the holding member 8 into the insertion hole 23 so that the cap 82 is directed downward (inside) from the inside of the instrument main body 2, and tightens the nut 83 on the upper side of the main body 81 on the outside of the instrument main body 2. Then, the holding member 8 is fixed to the top plate 21 of the instrument main body 2. Next, the operator inserts the electric wire 7 wired on the ceiling 110 into the holding member 8, pulls out the inside of the instrument body 2, and tightens the cap 82 to fix the electric wire 7 to the holding member 8. Then, the worker arranges the tool main body 2 so that the top plate 21 enters the ceiling space 110 into the embedding hole 111 provided in the ceiling material 100, and inserts the suspension bolt 101 provided in the ceiling space 110 into the bolt hole. 20 and tighten the nut 102.

さらに、作業者は、基台取付部材25を器具本体2に取り付け、端子台6が予め取り付けられている基台3を基台取付部材25に取り付ける。このとき、電線7は、基台3の上側に引き回されて基台通線孔424に通され、端子台6に接続される(図4参照)。そして、作業者は、電源ユニット5が予め取付部材42の上面に取り付けられている光源ユニット4を、基台3に取り付ける。電源ユニット5は、上板311と光源ユニット4の取付部材42の上面とに挟まれるように、収容部31に収容される。このとき、金具本体441の左端が基台3の側板312に設けられた孔に挿入され、金具本体441の先端が側板312の当該孔に係止されることで光源ユニット4は、基台3に吊り下げられる。さらに、作業者は、第1係止ばね45を係止部35に引っ掛けて、光源ユニット4を基台3に取り付ける。最後に、作業者は、パネルユニット24を、パネル241が器具本体2の開口27を閉塞するように、一対の第2係止ばね246のそれぞれを対応する引掛片261に引掛けて器具本体2に取り付ける(図1参照)。本実施形態の照明器具1において、作業者は上述のように照明器具1を組立てることができ、電線7によって組立作業が阻害されずに、容易に光源ユニット4を基台3に取り付けることが可能である。また、本実施形態の照明器具1は、電線7が基台3の上側に引き回されているので、作業者は、電線7の配線の確認を容易に行うことができる。   Further, the operator attaches the base attachment member 25 to the instrument body 2 and attaches the base 3 on which the terminal block 6 is attached in advance to the base attachment member 25. At this time, the electric wire 7 is routed to the upper side of the base 3, passes through the base through hole 424, and is connected to the terminal block 6 (see FIG. 4). Then, the worker attaches the light source unit 4 in which the power supply unit 5 is previously attached to the upper surface of the attachment member 42 to the base 3. The power supply unit 5 is housed in the housing 31 so as to be sandwiched between the upper plate 311 and the upper surface of the mounting member 42 of the light source unit 4. At this time, the left end of the fitting body 441 is inserted into a hole provided in the side plate 312 of the base 3, and the tip of the fitting body 441 is locked in the hole of the side plate 312, so that the light source unit 4 Hanged on. Further, the worker hooks the first locking spring 45 on the locking portion 35 and attaches the light source unit 4 to the base 3. Finally, the operator hooks each of the pair of second locking springs 246 on the corresponding hook pieces 261 so that the panel unit 24 closes the opening 27 of the instrument body 2 so that the panel 241 closes the opening 27 of the instrument body 2. (See Fig. 1). In the lighting fixture 1 of the present embodiment, the worker can assemble the lighting fixture 1 as described above, and the light source unit 4 can be easily attached to the base 3 without the assembly work being hindered by the electric wires 7. It is. Further, in the lighting fixture 1 of the present embodiment, since the electric wires 7 are routed above the base 3, the worker can easily check the wiring of the electric wires 7.

なお、挿通孔23は、天板21に設けられる必要はなく、上下方向から見て光源ユニット4の投影範囲外であって、基台3の投影範囲であればよく、側板22に設けられてもよい。   The insertion hole 23 does not need to be provided in the top plate 21, and may be outside the projection range of the light source unit 4 when viewed from above and below the projection range of the base 3. Is also good.
