また、カバー4は、内周壁4aにおいて、雌ねじ部41と突条部40(他端)との間に段差42を設け、上記段差42の境界に円環状に立設する段差面42aにパッキン9を備えている。パッキン9は、例えばゴム等の弾性体により円環状に形成されているOリングであり、カバー4を取付板8に取り付けたときに、段差面42aと、雌ねじ部41及び雄ねじ部80のうち少なくとも一方とで挟持されるものである。上記パッキン9の弾性力により、雌ねじ部41と雄ねじ部80との密着を強くすることができる。   Further, the cover 4 is provided with a step 42 on the inner peripheral wall 4a between the female screw portion 41 and the protruding portion 40 (the other end), and the packing 9 is provided on the step surface 42a standing in an annular shape at the boundary of the step 42. It has. The packing 9 is an O-ring formed in an annular shape by an elastic body such as rubber, for example. When the cover 4 is attached to the attachment plate 8, at least one of the step surface 42 a, the female screw portion 41, and the male screw portion 80. It is sandwiched between one and the other. Due to the elastic force of the packing 9, the close contact between the female screw portion 41 and the male screw portion 80 can be strengthened.
次に、本実施形態の照明器具の天井板Aへの取付手順について説明する。先ず、本体1を各取付穴100,101(図1(b)参照)の位置でねじ止め固定して本体1を天井板Aの表面に取り付ける。続いて、各嵌合穴200に突部103を嵌合させて取付金具2を本体1に取り付ける。さらに、点灯ユニット5と、電源用端子台6と、LEDユニット7とを取付板8に取り付ける。次に、各取付ねじ82を、取付穴81及び抜け止めワッシャー83に挿入し、取付穴24にねじ合わせて、取付板8を取付金具2にねじ止め固定する。最後に、カバー4の段差面42aにパッキン9を備え、雌ねじ部41を雄ねじ部80にねじ合わせて、カバー4を取付板8に取り付ける。   Next, the attachment procedure to the ceiling board A of the lighting fixture of this embodiment is demonstrated. First, the main body 1 is fixed to the surface of the ceiling board A by screwing and fixing the main body 1 at the positions of the respective mounting holes 100 and 101 (see FIG. 1B). Subsequently, the fitting 103 is attached to the main body 1 by fitting the protrusion 103 into each fitting hole 200. Further, the lighting unit 5, the power supply terminal block 6, and the LED unit 7 are attached to the mounting plate 8. Next, each mounting screw 82 is inserted into the mounting hole 81 and the retaining washer 83 and screwed into the mounting hole 24 to fix the mounting plate 8 to the mounting bracket 2 with screws. Finally, the packing 9 is provided on the stepped surface 42 a of the cover 4, the female screw portion 41 is screwed to the male screw portion 80, and the cover 4 is attached to the mounting plate 8.
上記照明器具において、LED71(図3参照)を含むLEDユニット7及び点灯ユニット5から発生した熱の流れについて説明する。LEDユニット7及び点灯ユニット5から発生した熱は、取付板8に伝導する。取付板8に伝導した熱は、雌ねじ部41及びパッキン9を介してカバー4に伝導する。カバー4は放熱を行う。これにより、上記照明器具は、放熱を高くすることができる。   The flow of heat generated from the LED unit 7 including the LED 71 (see FIG. 3) and the lighting unit 5 in the lighting fixture will be described. Heat generated from the LED unit 7 and the lighting unit 5 is conducted to the mounting plate 8. The heat conducted to the mounting plate 8 is conducted to the cover 4 through the female screw portion 41 and the packing 9. The cover 4 performs heat dissipation. Thereby, the said lighting fixture can make heat dissipation high.
以上、本実施形態によれば、LEDユニット7から発生する熱が取付板8に伝導することができ、さらに取付板8に伝導した熱がカバー4の両端に向かって伝導することができるので、大型にすることなく、LEDユニット7から発生する熱の放熱を高くすることができる。また、パッキン9の弾性力により、雌ねじ部41と雄ねじ部80との密着を強くすることができるので、雌ねじ部41と雄ねじ部80とのねじ止めが緩むことを防止することができるとともに、カバー4と取付板8との間の熱伝導を向上させることができる。さらに、LEDユニット7、点灯ユニット5及び電源用端子台6を取付板8に設置するので、点灯ユニット5から発生する熱が取付板8に伝導することができるとともに、結線作業を容易に行うことができる。   As described above, according to the present embodiment, the heat generated from the LED unit 7 can be conducted to the mounting plate 8, and the heat conducted to the mounting plate 8 can be conducted toward both ends of the cover 4. Heat dissipation of the heat generated from the LED unit 7 can be increased without increasing the size. In addition, since the close contact between the female screw portion 41 and the male screw portion 80 can be strengthened by the elastic force of the packing 9, it is possible to prevent the screwing between the female screw portion 41 and the male screw portion 80 from being loosened, and to cover the cover. The heat conduction between 4 and the mounting plate 8 can be improved. Furthermore, since the LED unit 7, the lighting unit 5 and the power terminal block 6 are installed on the mounting plate 8, heat generated from the lighting unit 5 can be conducted to the mounting plate 8 and the wiring work can be easily performed. Can do.
なお、本実施形態の変形例として、カバーが、例えばゴム、ばね等の弾性体を、段差面の複数の位置に備えてもよい。例えば、複数のゴムを、それぞれ離隔して段差面に備えてもよい。また、複数のばねを、それぞれ離隔して、雌ねじ部及び雄ねじ部のうち少なくとも一方に一端が接し、段差面に他端が接するように備えてもよい。このような構成にしても、弾性体の弾性力により、雌ねじ部と雄ねじ部との密着を強くすることができるので、雌ねじ部と雄ねじ部とのねじ止めが緩むことを防止することができるとともに、カバーと取付板との間の熱伝導を向上させることができる。   As a modification of the present embodiment, the cover may include elastic bodies such as rubber and springs at a plurality of positions on the step surface. For example, a plurality of rubbers may be provided on the stepped surface separately from each other. Further, the plurality of springs may be separated from each other so that one end is in contact with at least one of the female screw portion and the male screw portion and the other end is in contact with the step surface. Even in such a configuration, the elastic force of the elastic body can strengthen the close contact between the female screw portion and the male screw portion, so that the screwing between the female screw portion and the male screw portion can be prevented from loosening. The heat conduction between the cover and the mounting plate can be improved.
