A substantially circular light receiving window 62 for facing and a substantially circular opening window 63 having a diameter larger than that of the light receiving window 62 are provided so as to penetrate between the peripheral edge of the light receiving window 62 and the peripheral edge of the open window 63. A first inclined portion 60 and a second inclined portion 61 are formed. In addition, since the opening window 63 is penetrated by the cover 32 inclined in the upper right direction, it is inclined in the upper right direction.

第一の傾斜部６０及び第二の傾斜部６１は、受光窓６２の周縁と開口窓６３の周縁とを繋ぐように擂り鉢状に一体となって形成されており、第一の傾斜部６０は、左右方向において受光素子４０の光軸よりも左側、即ちダクト本体２に近い方に、第二の傾斜部６１は、左右方向において受光素子４０の光軸よりも右側、即ちダクト本体２から遠い方に設けられ、何れもカバー３２と一体に形成されている。 The first inclined portion 60 and the second inclined portion 61 are integrally formed in a bowl shape so as to connect the peripheral edge of the light receiving window 62 and the peripheral edge of the opening window 63.

However, any part of the bottom wall 30 that is curved is penetrated. For example, a cover 32 may be provided on the left side of the bottom wall portion 30 and penetrated through the cover 32. Further, the inner surfaces of the first inclined portion 60 and the second inclined portion 61 may be reflective surfaces so that a radio signal transmitted from an external remote controller can be reflected and guided to the light receiving element 40.

以下、本実施形態の配線ダクトを天井７に取り付ける方法を図３を用いて説明する。本実施形態の配線ダクトを天井７に取り付けるには、まず略矩形状の取付板９を天井７に設けられた引掛シーリングボディ又は引掛シーリングローゼットに取り付ける必要がある。以下では、天井７に引掛シーリングボディが設けられている場合について説明する。取付板９の前側略中央には、略円形状の挿通孔９０が貫設されており、この挿通孔９０の周囲には、４つの略円弧状の取付孔９３が周方向に亘って等間隔に貫設されている。また、取付板９の前端部及び後端部には、それぞれ略矩形状の取付片９１が下方に向かって突設されており、各取付片９１の略中央には組立ネジ３１ｂが挿通される保持部取付孔９２が貫設されている。 Hereinafter, a method of attaching the wiring duct of the present embodiment to the ceiling 7 will be described with reference to FIG. In order to attach the wiring duct of the present embodiment to the ceiling 7, it is necessary to first attach the substantially rectangular attachment plate 9 to the hooking sealing body or the hooking ceiling closet provided on the ceiling 7. Below, the case where the ceiling 7 is provided with the hooking sealing body is demonstrated. A substantially circular insertion hole 90 is provided substantially at the front center of the mounting plate 9, and around the insertion hole 90, four substantially arc-shaped mounting holes 93 are equally spaced in the circumferential direction. It is penetrated by. Further, a substantially rectangular attachment piece 91 projects downward from the front end portion and the rear end portion of the attachment plate 9, and an assembly screw 31 b is inserted through the approximate center of each attachment piece 91. A holding portion mounting hole 92 is provided therethrough.

取付板９を天井７に取り付けるには、まず天井７に設けられた引掛シーリングボディを挿通孔９０に挿通させ、引掛シーリングボディ周縁に備え付けられた取付ネジ（図示せず）の頭部を取付孔９３の大径端部９３ａに挿通させた後に取付板９を時計回りに回転させることで取付板９が引掛シーリングボディに固定される。次に、保持部３の引掛シーリングキャップ８を引掛シーリングボディに接続し、保持部３の側壁部３１にそれぞれ貫設された丸孔３１ａと取付板９の保持部取付孔９２とを重ね合わせ、組立ネジ３１ｂを挿通して螺合することで取付板９に保持部３を取付固定する。その後、図２に示すように、ダクト本体２上面の前後両端部に設けられて上下方向に伸縮自在のアジャスタ２１を調整し、各アジャスタ２１の上端部を天井７に当接させることで、ダクト本体２が傾かないように本実施形態の配線ダクトが天井７に取り付けられる。 In order to attach the mounting plate 9 to the ceiling 7, first, the hooking sealing body provided on the ceiling 7 is inserted into the insertion hole 90, and the heads of mounting screws (not shown) provided on the periphery of the hooking sealing body are attached to the mounting holes. The mounting plate 9 is fixed to the hooking sealing body by rotating the mounting plate 9 clockwise after being inserted through the large-diameter end portion 93a of 93. Next, the hooking sealing cap 8 of the holding part 3 is connected to the hooking sealing body, and the round holes 31 a respectively penetrating the side wall part 31 of the holding part 3 and the holding part mounting holes 92 of the mounting plate 9 are overlapped, The holding portion 3 is attached and fixed to the attachment plate 9 by inserting and screwing the assembly screw 31b. Thereafter, as shown in FIG. 2, the adjusters 21 that are provided at the front and rear ends of the upper surface of the duct body 2 and can be expanded and contracted in the vertical direction are adjusted, and the upper ends of the adjusters 21 are brought into contact with the ceiling 7. The wiring duct of this embodiment is attached to the ceiling 7 so that the main body 2 does not tilt.

上述のように、受光素子４０を保持部３の内部に配置することで、受光素子４０を目立たなくすることができ、したがって配線ダクトの外観を損なうことがない。また、カバー３２に受光窓６２及び開口窓６３を貫設し、受光窓６２の周縁と開口窓６３の周縁とを繋ぐように第一の傾斜部６０及び第二の傾斜部６１を擂り鉢状に形成したので、受光素子４０の無線信号の受光範囲を広げることができ、したがって無線信号の受信感度を向上することができる。また、保持部３の底壁部３０にダクト本体２の上面が取り付けられるためにダクト本体２の開口部２２が塞がれることがないので、照明器具の取り付け箇所の制限が無くなり、したがって照明器具をダクト本体２の給電部材１の何れの位置にも自由に取り付けることができる。 As described above, the light receiving element 40 can be made inconspicuous by disposing the light receiving element 40 inside the holding portion 3, and thus the appearance of the wiring duct is not impaired. Further, the light receiving window 62 and the opening window 63 are provided through the cover 32, and the first inclined portion 60 and the second inclined portion 61 are formed in a bowl shape so as to connect the periphery of the light receiving window 62 and the periphery of the opening window 63.

Moreover, since the upper surface of the duct main body 2 is attached to the bottom wall portion 30 of the holding portion 3, the opening 22 of the duct main body 2 is not blocked, so that there is no restriction on the mounting location of the lighting fixture, and therefore the lighting fixture. Can be freely attached to any position of the power feeding member 1 of the duct body 2.

また、第一の傾斜部６０及び第二の傾斜部６１をそれぞれ受光素子４０の光軸に対して前述の角度となるように配設したので、受光素子４０の受光範囲を広げると共に、ダクト本体２の中央部近傍に取り付けられた照明器具によって反射される無線信号を受信し易くなり、したがって無線信号の受信感度を向上することができる。 Further, since the first inclined portion 60 and the second inclined portion 61 are arranged so as to have the above-described angles with respect to the optical axis of the light receiving element 40, the light receiving range of the light receiving element 40 is widened, and the duct body. It becomes easy to receive the radio signal reflected by the lighting fixture attached near 2 center part, Therefore Therefore, the receiving sensitivity of a radio signal can be improved.

尚、底壁部３０のカバー３２において開口窓６３を貫設せずに、開口窓６３に当たる箇所を外部のリモコンから送信される無線信号を透過する半透明の別材料で形成するようにしてもよく、この場合も上記と同様の効果を奏することができる。 In the cover 32 of the bottom wall portion 30, the opening window 63 is not penetrated, and the portion that contacts the opening window 63 is formed of a semi-transparent material that transmits a radio signal transmitted from an external remote controller. In this case, the same effect as described above can be obtained.
