Description

本発明は、天井板などの取り付け板にあけられた取り付け開口に埋め込んで取り付ける埋込型のＬＥＤ照明器具に関する。 The present invention relates to an embedded LED lighting apparatus that is embedded in a mounting opening formed in a mounting plate such as a ceiling plate.

近年、ＬＥＤを用いた照明器具では高出力化（大光量化）が求められており、照明器具の器具発光面が大型化し、ＬＥＤを実装するＬＥＤ基板が大きくなり、ＬＥＤ基板からの発熱量が大きくなっている。ＬＥＤ基板からの発熱量の増大に伴いヒートシンクも大きくなり、照明器具全体の重量が増大している。 In recent years, there has been a demand for higher output (higher light intensity) in lighting fixtures using LEDs, the lighting surface of the lighting fixtures has become larger, the LED substrate on which the LEDs are mounted has become larger, and the amount of heat generated from the LED substrates has increased. It is getting bigger. As the amount of heat generated from the LED substrate increases, the heat sink also increases, and the weight of the entire lighting fixture increases.

従来では、バネの復元力を用いた２個ないし３個の取付装置（例えば特許文献１の取付装置３）で、照明器具を天井に取り付けていた。しかし、ヒートシンクの大型化に伴い照明器具の重量が増大すると、２、３個の取付装置で照明装置を固定することが困難となる。また、特許文献２の本体取付バネでは、照明器具の重量をささえられない場合もある。 Conventionally, the lighting fixture is attached to the ceiling with two to three attachment devices (for example, the attachment device 3 of Patent Document 1) using a restoring force of a spring. However, when the weight of the lighting fixture increases with the increase in size of the heat sink, it becomes difficult to fix the lighting device with a few attachment devices. In addition, the body mounting spring of Patent Document 2 may not support the weight of the lighting fixture.

照明器具の重量を支えることが可能なバネとした場合、バネの復元力が強くなりすぎてしまい、天井を破損する可能性もある。 When a spring capable of supporting the weight of the lighting fixture is used, the restoring force of the spring becomes too strong, and the ceiling may be damaged.

照明器具の重量を支持しつつ天井破損の防止を図るため、例えば特許文献３で使用しているような板ばねを４個以上用いることも考えられるが、各板ばねの取り付けの際、各板バネを同時に抑えることが困難であり、作業性も悪化する。 In order to prevent damage to the ceiling while supporting the weight of the lighting fixture, for example, four or more leaf springs as used in Patent Document 3 may be used. It is difficult to suppress the springs at the same time, and workability is also deteriorated.

また、特許文献１の取付装置を３個以上とした場合は作業性は良好であるが、バネＡＳＳＹの幅が太いため、埋め込み穴径の小さな器具には対応ができなくなってしまう。 Further, when the number of attachment devices of Patent Document 1 is three or more, the workability is good, but since the width of the spring ASSY is large, it becomes impossible to deal with an instrument having a small embedded hole diameter.

また、照明装置の取付装置は、地震等により振動が発生した場合に、照明装置を固定、保持することが要求される。取付装置として板バネを用いる場合は、左右方向（水平方向）、及び上下方向の動きを規制することはできるが、さまざまな板厚の天井板に対応することが困難である。つまり、板厚の薄い天井板に対しては、側面でみて板バネ形状が水平気味になるので上下方向の支持力は大きいが、板厚の厚い天井板の場合は側面で見て板バネ形状が垂直側に近づくので上下方向の支持力は小さくなる。すなわち、板バネの場合には上下方向の支持に課題がある。 In addition, the mounting device for the lighting device is required to fix and hold the lighting device when vibration occurs due to an earthquake or the like. When a leaf spring is used as the attachment device, it is possible to restrict the movement in the left-right direction (horizontal direction) and the up-down direction, but it is difficult to cope with ceiling plates having various plate thicknesses. In other words, for a ceiling plate with a thin plate thickness, the leaf spring shape looks horizontal when viewed from the side, so the supporting force in the vertical direction is large. Since it approaches the vertical side, the vertical supporting force is reduced. That is, in the case of a leaf spring, there is a problem in support in the vertical direction.

特許文献１のような取付装置の場合は、上下方向の動きは規制するが、横方向の動きが規制できない。その為、埋め込み穴（天井穴）との間にクリアランスがあると、照明器具自体が水平方向に動いてしまう。 In the case of a mounting device like patent document 1, although the motion of an up-down direction is controlled, the motion of a horizontal direction cannot be controlled. Therefore, if there is a clearance between the embedding hole (ceiling hole), the luminaire itself moves in the horizontal direction.

（照明器具６００の特徴）
照明器具６００は、例えば天井板（取付板）などの取付開口穴に埋め込まれた状態で使用される天井埋込型の照明器具である。実施の形態１に係る照明器具６００の特徴は、以下の点である。照明器具６００は、図３、あるいは図５（ｂ）、（ｃ）に示すように、３個の「板バネ６７１」が化粧枠６７６の周に沿って、照明器具６００が天井板に設置されたときの化粧枠天井側に取り付けられる。また、３個の「止め具６７２」が化粧枠６７６の周に沿って、化粧枠天井側に取り付けられる。図３に示すように、それぞれの止め具６７２は、板バネ６７１どうしの間に配置される。
図６は、板バネ６７１、止め具６７２によって、天井板６８０に対して照明器具６００の移動が拘束される状態を示す図である。照明器具６００は、上面６８０Ａと下面６８０Ｂとを有し略水平に配置される天井板６８０（取付板）にあけられた取付開口穴６８１に、下面６８０Ｂ側から埋め込まれることで天井板６８０に取り付けられる。図６（ａ）は、照明器具６００が天井板６８０に取り付けられた場合の断面図であり、図６（ａ）の断面Ａ−Ａに相当する。図６（ｂ）は、図６（ａ）のＸ方向矢視を模式的に描いた図であり、板バネ６７１、止め具６７２は、Ｘ方向矢視で、化粧枠６７６の周に略６０度間隔で配置される。図６（ａ）に示すように、止め具６７２の押え金具６７２−６は、化粧枠６７６の外向フランジ部６７６−１と共に照明器具６００の天井板６８０に対する上下方向（白抜き矢印）の移動を拘束する。また、板バネ６７１は、天井板６８０に開けられた取付開口穴６８１の天井板６８０の上面６８０Ａ側の縁をＹ方向に押圧することで照明器具６００の水平方向の移動を拘束（白抜き矢印方）する。すなわち板バネ６７１は、Ｘ方向矢視（図６（ｂ））において、化粧枠６７６の円形状の周に沿って略１２０度おきに配置されており、Ｙ１方向に取付開口穴６８１の縁を押圧するので照明器具６００の水平方向の移動が拘束される。板バネ６７１、止め具６７２による照明器具６００の移動拘束の詳細は、後述する。このように照明器具６００の特徴は、照明器具６００が３個の板バネ６７１と、板バネ６７１どうしの間に配置された３個の止め具６７２とを備え、照明器具６００は止め具６７２と外向フランジ部６７６−１とで上下方向の動きが規制され、板バネ６７１で水平方向の動きが規制されることで、耐振動性能が向上する点にある。このように、３つの止め具６７２は、照明器具６００が取付開口穴６８１に埋め込まれると、天井板６８０の上面６８０Ａを、略鉛直方向（図６（ａ）のＺ方向）に押圧することで照明器具６００を支持する。また３つの板バネ６７１は、照明器具６００が取付開口穴６８１に埋め込まれると、取付開口穴６８１の上面６８０Ａ側の周縁を、略鉛直方向と略水平方向との成分に分解可能な斜め方向（図６（ａ）のＹ方向）にバネ復元力に基づく押圧力によって押圧することで照明器具６００を支持する。 (Characteristics of lighting fixture 600)
The lighting fixture 600 is a ceiling-embedded lighting fixture that is used in a state of being embedded in a mounting opening hole such as a ceiling plate (mounting plate). The features of lighting fixture 600 according to Embodiment 1 are as follows. As shown in FIG. 3 or FIGS. 5 (b) and 5 (c), the lighting fixture 600 has three “plate springs 671” along the circumference of the decorative frame 676, and the lighting fixture 600 is installed on the ceiling plate. It is attached to the ceiling side of the decorative frame. Three “stoppers 672” are attached to the decorative frame ceiling side along the circumference of the decorative frame 676. As shown in FIG. 3, each stopper 672 is disposed between the leaf springs 671.
FIG. 6 is a diagram illustrating a state in which the movement of the lighting fixture 600 is restrained with respect to the ceiling plate 680 by the leaf spring 671 and the stopper 672. The lighting fixture 600 has an upper surface 680A and a lower surface 680B and is attached to the ceiling plate 680 by being embedded from the lower surface 680B side into a mounting opening hole 681 formed in the ceiling plate 680 (mounting plate) arranged substantially horizontally. It is done. FIG. 6A is a cross-sectional view when the lighting fixture 600 is attached to the ceiling plate 680, and corresponds to a cross-section AA in FIG. FIG. 6B is a diagram schematically illustrating the X direction arrow of FIG. 6A, and the leaf spring 671 and the stopper 672 are approximately 60 around the decorative frame 676 in the X direction arrow. Arranged at degree intervals. As shown in FIG. 6A, the holding bracket 672-6 of the stopper 672 moves in the vertical direction (open arrow) with respect to the ceiling plate 680 of the lighting fixture 600 together with the outward flange portion 676-1 of the decorative frame 676. to bound. Further, the leaf spring 671 restrains the horizontal movement of the lighting fixture 600 by pressing the edge on the upper surface 680A side of the ceiling plate 680 of the mounting opening hole 681 formed in the ceiling plate 680 (white arrow). To) That is, the leaf springs 671 are arranged at intervals of approximately 120 degrees along the circular circumference of the decorative frame 676 in the X direction arrow (FIG. 6B), and the edges of the mounting opening holes 681 are arranged in the Y1 direction. Since it presses, the horizontal movement of the lighting fixture 600 is restrained. Details of the movement restraint of the luminaire 600 by the leaf spring 671 and the stopper 672 will be described later. Thus, the lighting fixture 600 is characterized in that the lighting fixture 600 includes three leaf springs 671 and three stoppers 672 disposed between the leaf springs 671, and the lighting fixture 600 includes the stoppers 672. The movement in the vertical direction is restricted by the outward flange portion 676-1, and the movement in the horizontal direction is restricted by the leaf spring 671, so that the vibration resistance performance is improved. As described above, when the lighting fixture 600 is embedded in the mounting opening hole 681, the three stoppers 672 are configured to press the upper surface 680A of the ceiling plate 680 in a substantially vertical direction (Z direction in FIG. 6A). The lighting fixture 600 is supported. Further, the three leaf springs 671 are arranged in an oblique direction (when the lighting fixture 600 is embedded in the attachment opening hole 681, the peripheral edge on the upper surface 680 </ b> A side of the attachment opening hole 681 can be decomposed into components of a substantially vertical direction and a substantially horizontal direction ( The lighting fixture 600 is supported by pressing with a pressing force based on the spring restoring force in the Y direction in FIG.

次に図２を参照して、照明器具６００の構成を説明する。照明器具６００は、放熱部６１０、絶縁シート６２０、ＬＥＤ基板６３０、押さえ枠６５０、カバー６６０、反射部６７０を備える。 Next, the configuration of the lighting fixture 600 will be described with reference to FIG. The lighting fixture 600 includes a heat radiating portion 610, an insulating sheet 620, an LED substrate 630, a holding frame 650, a cover 660, and a reflecting portion 670.

（放熱部６１０）
放熱部６１０は、ＬＥＤ基板６３０が取り付けられる基板取付面６１１（平坦部）を備える。放熱部６１０は、基板取付面６１１に取り付けられたＬＥＤ基板６３０に実装されたＬＥＤ６４０から発せられる熱を放熱するヒートシンクである。基板取付面６１１の裏側には、ＬＥＤ６４０から発せられる熱を効率よく放熱するための放熱フィン６１９が設けられる。放熱部６１０は、熱を伝達する金属、例えば、アルミニウムにより形成される。 (Heat dissipation part 610)
The heat dissipation part 610 includes a board attachment surface 611 (flat part) to which the LED board 630 is attached. The heat dissipating unit 610 is a heat sink that dissipates heat generated from the LED 640 mounted on the LED substrate 630 attached to the substrate attaching surface 611. On the back side of the board mounting surface 611, heat radiating fins 619 for efficiently radiating the heat generated from the LEDs 640 are provided. The heat dissipating part 610 is formed of a metal that transfers heat, for example, aluminum.

（絶縁シート６２０）
絶縁シート６２０は、ＬＥＤ基板６３０と基板取付面６１１との間に配置される。絶縁シート６２０は、ＬＥＤ基板６３０の断面から露出する金属部分と基板取付面６１１との間を電気的に絶縁する。絶縁シート６２０は、ＬＥＤ基板６３０の周縁の断面から露出する金属部分と基板取付面６１１との絶縁距離を確保するため、ＬＥＤ基板６３０よりも大きく形成される。 (Insulation sheet 620)
The insulating sheet 620 is disposed between the LED substrate 630 and the substrate mounting surface 611. The insulating sheet 620 electrically insulates the metal part exposed from the cross section of the LED substrate 630 and the substrate mounting surface 611. The insulating sheet 620 is formed larger than the LED substrate 630 in order to secure an insulating distance between the metal portion exposed from the cross section of the peripheral edge of the LED substrate 630 and the substrate mounting surface 611.

（ＬＥＤ基板６３０）
ＬＥＤ基板６３０は、光源である複数のＬＥＤ６４０が実装される実装面６３４と、実装面６３４の裏側の面である非実装面６３５（裏面）とを有する。ＬＥＤ基板６３０は、例えば、アルミニウム基板である。 (LED board 630)
The LED substrate 630 includes a mounting surface 634 on which a plurality of LEDs 640 that are light sources are mounted, and a non-mounting surface 635 (back surface) that is a back surface of the mounting surface 634. The LED substrate 630 is, for example, an aluminum substrate.

（基板取付ねじ６３１）
基板取付ねじ６３１（固定ねじ）は、ＬＥＤ基板６３０の所定の箇所を基板取付面６１１に固定するためのねじである。基板取付ねじ６３１は、経年劣化が少なく信頼性の高い金属性のねじである。ブッシュ６３２は、絶縁材により形成されており、基板取付ねじ６３１の一部を覆って、基板取付ねじ６３１の絶縁を確保するための部材である。 (Board mounting screw 631)
The board mounting screw 631 (fixing screw) is a screw for fixing a predetermined portion of the LED board 630 to the board mounting surface 611. The board mounting screw 631 is a highly reliable metal screw with little deterioration over time. The bush 632 is formed of an insulating material and is a member that covers a part of the board mounting screw 631 and ensures insulation of the board mounting screw 631.

（ＬＥＤ基板６３０）
ＬＥＤ基板６３０は、ブッシュ６３２と基板取付ねじ６３１のねじ軸部６３１ｂ（ねじ棒）とを貫通させる基板貫通孔６３３を中央部に有する。本実施の形態では、ＬＥＤ基板６３０の中央部分を基板取付面６１１に固定する場合について説明するが、基板取付面６１１に固定するＬＥＤ基板６３０上の位置は、中央部分以外の箇所でもよい。基板取付面６１１に固定するＬＥＤ基板６３０上の位置に関わらず、本実施の形態を適用することができる。 (LED board 630)
The LED substrate 630 has a substrate through hole 633 in the center portion through which the bush 632 and the screw shaft portion 631b (screw rod) of the substrate mounting screw 631 are passed. In the present embodiment, the case where the central portion of the LED substrate 630 is fixed to the substrate mounting surface 611 will be described. However, the position on the LED substrate 630 fixed to the substrate mounting surface 611 may be a location other than the central portion. This embodiment can be applied regardless of the position on the LED substrate 630 that is fixed to the substrate mounting surface 611.

ＬＥＤ基板６３０は、実装面６３４にＬＥＤ６４０（光源）を実装する。ＬＥＤ基板６３０の非実装面６３５は、基板取付面６１１と面接触するように取り付けられる。本実施の形態では、非実装面６３５は、絶縁シート６２０を介して放熱部６１０の基板取付面６１１に当接（面接触）する。 The LED board 630 mounts the LED 640 (light source) on the mounting surface 634. The non-mounting surface 635 of the LED substrate 630 is attached so as to be in surface contact with the substrate attachment surface 611. In the present embodiment, the non-mounting surface 635 comes into contact (surface contact) with the board mounting surface 611 of the heat radiating portion 610 through the insulating sheet 620.

（絶縁シート６２０）
上述したように、絶縁シート６２０は、ＬＥＤ基板６３０の周縁の断面から露出する金属部分と基板取付面６１１との絶縁距離を確保するために用いられる。しかし、例えば、ＬＥＤ基板６３０の周縁の断面から金属部分が露出しないようにコーティングする等の加工を施すことにより、絶縁シート６２０を省くことができる場合がある。以下の説明において、「非実装面６３５と基板取付面６１１とが面接触する」、「非実装面６３５と基板取付面６１１とが当接する」、「非実装面６３５と基板取付面６１１とが密着する」等と記載した場合には、絶縁シート６２０あるいはコーティング等により、ＬＥＤ基板６３０と基板取付面６１１との間が絶縁されていることが前提である。 (Insulation sheet 620)
As described above, the insulating sheet 620 is used to secure an insulating distance between the metal portion exposed from the cross section of the peripheral edge of the LED substrate 630 and the substrate mounting surface 611. However, for example, the insulating sheet 620 may be omitted by performing processing such as coating so that the metal portion is not exposed from the cross section of the peripheral edge of the LED substrate 630. In the following description, “the non-mounting surface 635 and the board mounting surface 611 are in surface contact”, “the non-mounting surface 635 and the board mounting surface 611 are in contact”, “the non-mounting surface 635 and the board mounting surface 611 are In the case of “contacting” or the like, it is assumed that the LED substrate 630 and the substrate mounting surface 611 are insulated by the insulating sheet 620 or the coating.

ＬＥＤ基板６３０の非実装面６３５と放熱部６１０の基板取付面６１１とは、面接触するとともに熱接続している。基板取付面６１１は、ＬＥＤ基板６３０に実装されているＬＥＤ６４０から発生する熱を受け取る。そして、基板取付面６１１で受け取られた熱は、放熱部６１０の放熱フィン６１９から放熱される。このとき、基板取付面６１１がＬＥＤ６４０から発生する熱を効率よく受け取ることができるように、基板取付面６１１とＬＥＤ基板６３０の非実装面６３５とはできるだけ密着させることが好ましい。 The non-mounting surface 635 of the LED substrate 630 and the substrate mounting surface 611 of the heat radiation part 610 are in surface contact and thermally connected. The board mounting surface 611 receives heat generated from the LEDs 640 mounted on the LED board 630. Then, the heat received by the board mounting surface 611 is radiated from the radiating fins 619 of the radiating unit 610. At this time, it is preferable that the board mounting surface 611 and the non-mounting surface 635 of the LED board 630 are as close as possible so that the board mounting surface 611 can efficiently receive the heat generated from the LEDs 640.

（押さえ枠６５０）
押さえ枠６５０は、開口を有するリング状（環状）の枠である。押さえ枠６５０は、ＬＥＤ基板６３０の実装面６３４の周縁近傍を基板取付面６１１方向に押し付けながら基板取付面６１１に固定される。これにより、ＬＥＤ基板６３０の周縁近傍を基板取付面６１１に固定させる。押さえ枠６５０は、開口部分にＬＥＤ６４０が位置するようにＬＥＤ６４０の周囲に配置される。 (Presser frame 650)
The holding frame 650 is a ring-shaped (annular) frame having an opening. The holding frame 650 is fixed to the board mounting surface 611 while pressing the vicinity of the periphery of the mounting surface 634 of the LED board 630 toward the board mounting surface 611. As a result, the vicinity of the periphery of the LED substrate 630 is fixed to the substrate mounting surface 611. The holding frame 650 is arranged around the LED 640 so that the LED 640 is positioned in the opening portion.

（カバー６６０）
カバー６６０は、押さえ枠６５０の開口に位置するＬＥＤ６４０を覆うように基板取付面６１１に固定される。 (Cover 660)
The cover 660 is fixed to the board mounting surface 611 so as to cover the LED 640 located at the opening of the holding frame 650.

（止め具６７２の動作）
図１０〜図１３を参照して、止め具６７２（押え金具６７２−６）の動作を説明する。止め具６７２は様々なタイプが考えられるが、以下では、止め具６７２を、照明器具本体５０１に配置される取付装置５０３として説明する。すなわち、図１〜図９で述べた止め具６７２は、取付装置５０３の構成とする。 (Operation of stopper 672)
The operation of the stopper 672 (holding metal 672-6) will be described with reference to FIGS. Various types of the stopper 672 can be considered. In the following, the stopper 672 will be described as an attachment device 503 disposed on the lighting fixture body 501. That is, the stopper 672 described with reference to FIGS.

図１０は、照明器具本体５０１の斜視図である。図１０において、照明器具本体５０１は、下端外周縁部に外向フランジ部５０２が設けられている。照明器具本体５０１は、照明器具本体５０１を天井に取り付けるための取付装置５０３を備える。取付装置５０３は照明器具本体５０１を挟んで対称位置に各１個設置されている。取付装置５０３は一端が照明器具本体５０１の外向フランジ部５０２に固定されたアーム５０４、交差部がアーム５０４の下端部に取り付けられたＶ型バネ５０５、アーム５０４とＶ型バネ５０５に係合してアーム５０４に沿って上下方向移動可能に取り付けられた押え金具５０６および押え金具５０６に係合して押え金具５０６を下方へ引き落す引き落し金具５０７から構成されている。 FIG. 10 is a perspective view of the lighting fixture body 501. In FIG. 10, the luminaire main body 501 is provided with an outward flange 502 at the outer peripheral edge at the lower end. The luminaire main body 501 includes an attachment device 503 for attaching the luminaire main body 501 to the ceiling. One mounting device 503 is installed at each symmetrical position across the lighting fixture body 501. The attachment device 503 is engaged with an arm 504 whose one end is fixed to the outward flange portion 502 of the luminaire main body 501, a V-shaped spring 505 that is attached to the lower end portion of the arm 504, and the arm 504 and the V-shaped spring 505. The presser fitting 506 is mounted so as to be movable in the vertical direction along the arm 504 and the pull-down fitting 507 that engages with the presser fitting 506 and pulls the presser fitting 506 downward.

アーム５０４は矩形状に形成され、その縁部５０４ａが内側（アーム５０４を照明器具本体５０１に取り付けたときにおける照明器具本体５０１側）に折り曲げられ断面コ字状に形成されている。アーム５０４の両側の縁部５０４ａにはスリット５０４ｂが設けられている。なお、このアーム５０４は外向フランジ部５０２に対してほぼ直角に立設されている。 The arm 504 is formed in a rectangular shape, and its edge portion 504a is bent inward (toward the lighting fixture body 501 when the arm 504 is attached to the lighting fixture body 501) and has a U-shaped cross section. Slits 504 b are provided at the edge portions 504 a on both sides of the arm 504. The arm 504 is erected substantially perpendicular to the outward flange portion 502.

次に、押え金具５０６の形状について説明する。押え金具５０６は矩形状の押え片５０６ａ、押え片５０６ａの上部両側に形成されたガイド片５０６ｂ、両ガイド片５０６ｂのすぐ下方に設けられＶ型バネ５０５と係合する係合片５０６ｃ、押え片５０６ａの下部両側に形成された押圧片５０６ｄを備えている。ガイド片５０６ｂはアーム５０４に設けられた両縁部５０４ａに係合して、押え金具５０６をアーム５０４の上下方向移動可能に案内する。 Next, the shape of the presser fitting 506 will be described. The presser fitting 506 includes a rectangular presser piece 506a, guide pieces 506b formed on both upper sides of the presser piece 506a, an engaging piece 506c that is provided immediately below both guide pieces 506b and engages with a V-shaped spring 505, and a presser piece. There are provided pressing pieces 506d formed on both sides of the lower part of 506a. The guide piece 506b engages with both edge portions 504a provided on the arm 504, and guides the presser fitting 506 so that the arm 504 can move in the vertical direction.

次に、引き落し金具５０７の形状について説明する。引き落し金具５０７は線材をＵ字状に曲げ加工して形成されたものであり、腕部５０７ａと両方の腕部５０７ａを接続する接続部５０７ｂとから構成されている。そして、腕部５０７ａの先端部は内方に折り曲げられさらに先端側が照明器具本体５０１側へ折り曲げられている。また、両腕部５０７ａの基端部は照明器具本体５０１から離れる方向へ折り曲げられ、外方へ突出している。 Next, the shape of the drop metal fitting 507 will be described. The drop-off fitting 507 is formed by bending a wire into a U-shape, and includes an arm portion 507a and a connecting portion 507b that connects both arm portions 507a. And the front-end | tip part of the arm part 507a is bent inward, and also the front end side is bent to the lighting fixture main body 501 side. Further, the base ends of both arms 507a are bent away from the luminaire body 501 and protrude outward.

図１１はＶ型バネ５０５をアーム５０４に組み付けた状態を示す斜視図である。図１１に基づいてＶ型バネ５０５の形状について説明する。Ｖ型バネ５０５は１本のバネ線材を曲げ加工して形成され、両脚部５０５ａ、両脚部５０５ａの交点部にコイル状に形成されたコイル状部５０５ｂ及び両脚部５０５ａの先端に形成されたリング部５０５ｃから構成されている。そして、両脚部５０５ａの中央より若干先端寄りの位置が外方向（アーム５０４を照明器具本体５０１に取り付けたときにおける照明器具本体５０１から離れる方向）でかつ両脚部５０５ａが近付く方向に折り曲げられ、先端折曲部５０５ｅが形成されている。 FIG. 11 is a perspective view showing a state in which the V-shaped spring 505 is assembled to the arm 504. The shape of the V-shaped spring 505 will be described with reference to FIG. The V-shaped spring 505 is formed by bending one spring wire, and a ring formed on both legs 505a, a coil-shaped portion 505b formed in a coil shape at the intersection of both legs 505a, and a tip formed on both legs 505a. It is comprised from the part 505c. Then, the position slightly closer to the tip than the center of both legs 505a is bent in the outward direction (the direction away from the luminaire main body 501 when the arm 504 is attached to the luminaire main body 501) and in the direction in which both legs 505a approach, A bent portion 505e is formed.

図１２はアーム５０４にＶ型バネ５０５を組み付けた状態の側面図である。この図から分かるように、Ｖ型バネ５０５の両脚部５０５ａとアーム５０４は所定の角度αを成して装着されている。 FIG. 12 is a side view of the arm 504 with the V-shaped spring 505 assembled thereto. As can be seen from this figure, both legs 505a of the V-shaped spring 505 and the arm 504 are mounted at a predetermined angle α.

次に、再び図１０に基づいて、上記のように構成されたアーム５０４、Ｖ型バネ５０５、押え金具５０６及び引き落し金具５０７の組み付け状態について説明する。図１０に示したように、Ｖ型バネ５０５の両脚部５０５ａは押し狭められた状態でその先端折曲部５０５ｅが押え金具５０６のガイド片５０６ｂに外方から把持されている。このときＶ型バネ５０５はその両側の先端折曲部５０５ｅがほぼ平行になると共に外方に向かって延出した形状になる。そのため押え片５０６ａはアーム５０４側に密着した状態でアーム５０４の上部に保持される。また、引き落し金具５０７はその先端部がアーム５０４のスリット５０４ｂに挿入されると共に、押え金具５０６のガイド片５０６ｂ上部に係合した状態でアーム５０４に取り付けられている。このとき、Ｖ型バネ５０５はその弾性により広がろうとしているが、先端折曲部５０５ｅがほぼ平行であるため、押え金具５０６に下向きの力を及ぼすことはない。この図１０に示す状態が照明器具本体５０１を天井に取り付ける前のセッティング状態である。 Next, referring to FIG. 10 again, the assembled state of the arm 504, the V-shaped spring 505, the presser fitting 506 and the drop-off fitting 507 configured as described above will be described. As shown in FIG. 10, both leg portions 505 a of the V-shaped spring 505 are pressed and narrowed, and the bent end portions 505 e are gripped from the guide pieces 506 b of the presser fitting 506 from the outside. At this time, the V-shaped spring 505 has a shape in which the tip bent portions 505e on both sides thereof are substantially parallel and extend outward. Therefore, the presser piece 506a is held on the upper portion of the arm 504 in a state of being in close contact with the arm 504 side. The tip of the drop-off fitting 507 is inserted into the slit 504b of the arm 504, and is attached to the arm 504 in a state of being engaged with the upper portion of the guide piece 506b of the holding fitting 506. At this time, the V-shaped spring 505 is going to expand due to its elasticity, but since the tip bent portion 505e is substantially parallel, no downward force is exerted on the presser fitting 506. The state shown in FIG. 10 is a setting state before the lighting fixture body 501 is attached to the ceiling.

次に、図１０のようにセッティングされた照明器具本体５０１を天井に取り付ける方法及びその際の取付装置５０３の動作を説明する。セッティング状態にある照明器具本体５０１を天井に設けた取付開口穴５１３に挿入する。そして、引き落し金具５０７の接続部５０７ｂが天井下面５１２に当接し、さらに照明器具本体５０１を押し上げると接続部５０７ｂが天井下面５１２により押し下げられる。接続部５０７ｂが押し下げられると、押え金具５０６のガイド片５０６ｂ上部に係合している引き落し金具５０７の先端部が押え金具５０６を引き下げることになる。 Next, a method of attaching the luminaire main body 501 set as shown in FIG. 10 to the ceiling and the operation of the attachment device 503 at that time will be described. The luminaire main body 501 in the setting state is inserted into a mounting opening hole 513 provided on the ceiling. Then, the connecting portion 507b of the drop-off fitting 507 comes into contact with the ceiling lower surface 512, and when the lighting fixture body 501 is further pushed up, the connecting portion 507b is pushed down by the ceiling lower surface 512. When the connecting portion 507b is pushed down, the tip end portion of the drop fitting 507 engaged with the upper portion of the guide piece 506b of the hold fitting 506 pulls down the hold fitting 506.

押え金具５０６が引き下げられ、押え金具５０６の係合片５０６ｃがＶ型バネ５０５の先端折曲部５０５ｅを通過してＶ形状部に至ると、Ｖ型バネ５０５の広がろうとする力が押え金具５０６の係合片５０６ｃに下方に向かう力を及ぼすことになる。また、このＶ形状部ではＶ型バネ５０５の両脚部５０５ａがアーム５０４と所定の角度αを成しているので、両脚部５０５ａに係合している押え金具５０６の係合片５０６ｃはその両端部の上部側がＶ型バネ５０５によって内方（照明器具本体５０１側方向）に押されることになる。その結果、押え金具５０６の押え片５０６ａの下端部がアーム５０４から浮き上がることになる。すなわち、押え金具５０６の係合片５０６ｃがＶ型バネ５０５のＶ形状部に至った状態では、Ｖ型バネ５０５は押え片５０６ａの下端部をアーム５０４から離れる方向に付勢すると共に押え金具５０６を下方へ移動させる方向にも付勢することになる。 When the presser fitting 506 is pulled down and the engaging piece 506c of the presser fitting 506 passes through the distal end bent portion 505e of the V-shaped spring 505 and reaches the V-shaped portion, the force for spreading the V-shaped spring 505 is increased. A downward force is applied to the engaging piece 506c of 506. Further, in this V-shaped portion, both legs 505a of the V-shaped spring 505 form a predetermined angle α with the arm 504, so that the engagement pieces 506c of the presser fitting 506 engaged with both legs 505a The upper side of the part is pushed inward (in the direction of the lighting fixture main body 501) by the V-shaped spring 505. As a result, the lower end portion of the presser piece 506 a of the presser fitting 506 is lifted from the arm 504. That is, in a state where the engaging piece 506c of the presser fitting 506 reaches the V-shaped portion of the V-shaped spring 505, the V-type spring 505 urges the lower end portion of the presser piece 506a away from the arm 504 and at the same time presser fitting 506. It will also be urged in the direction of moving down.

押え金具５０６はＶ型バネ５０５の付勢力によって押え片５０６ａの下端部をアーム５０４から浮き上がらせた状態でアーム５０４に沿って降下して押え片５０６ａの下端部が天井の上面５１１に当接すると、図１３に示すように押え片５０６ａの下端部と照明器具本体５０１の外向フランジ部５０２によって天井板５１０を挟持することになり、照明器具本体５０１は天井に取り付けられる。 The presser fitting 506 is lowered along the arm 504 in a state where the lower end portion of the presser piece 506a is lifted from the arm 504 by the urging force of the V-shaped spring 505, and the lower end portion of the presser piece 506a comes into contact with the upper surface 511 of the ceiling. As shown in FIG. 13, the ceiling plate 510 is sandwiched between the lower end portion of the holding piece 506a and the outward flange portion 502 of the luminaire main body 501, and the luminaire main body 501 is attached to the ceiling.

（天井面から取り外す場合）
次に、上記のようにして天井面に取り付けられた照明器具の取り外し方法及びその際の取付装置５０３の動作を説明する。照明器具を取り外すには、照明器具本体５０１を下方へ引き下げる。このとき、押え片５０６ａの下端部は天井の上面５１１に当接した状態で押え金具５０６がアーム５０４上を上方に移動する。そして、押え金具５０６の係合片５０６ｃがＶ型バネ５０５の両脚部５０５ａにおける折曲部を通過し、先端折曲部５０５ｅに至ると押え金具５０６のＣ型部が先端折曲部５０５ｅに沿って外方に移動し、図１０に示したように押え片５０６ａはアーム５０４側に密着する。このような状態になることによって、埋込式照明器具を取付開口穴５１３から下方に抜き取ることができる。 (When removing from the ceiling)
Next, a method for removing the lighting fixture attached to the ceiling surface as described above and the operation of the attachment device 503 at that time will be described. To remove the luminaire, the luminaire body 501 is pulled down. At this time, the presser fitting 506 moves upward on the arm 504 in a state where the lower end portion of the presser piece 506a is in contact with the upper surface 511 of the ceiling. Then, when the engagement piece 506c of the presser fitting 506 passes through the bent portions of both leg portions 505a of the V-shaped spring 505 and reaches the distal end bent portion 505e, the C-shaped portion of the presser fitting 506 follows the distal end bent portion 505e. As shown in FIG. 10, the presser piece 506a is in close contact with the arm 504 side. By entering such a state, the embedded lighting fixture can be extracted downward from the mounting opening hole 513.

図１４〜図１６を参照して、図１〜図９で述べた板バネ６７１の動作を説明する。以下では、板バネ６７１を、第１板バネ４０３ａと想定して説明する。すなわち、図１〜図９で述べた板バネ６７１は、第１板バネ４０３ａの構成とする。図１４は、照明器具の斜視図である。図１５は、図１４の照明器具を天井に固定するための板バネの配置説明図である。この照明器具は、ランプを内部に収納してランプの光を光出口４０１ａから射出するランプケース４０１（以下、ケース４０１という）、ケース４０１の光出口４０１ａの外周を構成して、取り付けようとする天井の開口周縁と係合する天井取付部材とを備える。ケース４０１は内側が光反射面として構成された筒状体であり、その外形は光出口４０１ａを形成している平面と直交するケース４０１の中心軸に対して基本的に対称となっている。なお、ケース４０１は筒状に限らず、回転楕円状、半球状等他の形状であってもよい。 The operation of the leaf spring 671 described in FIGS. 1 to 9 will be described with reference to FIGS. Hereinafter, the plate spring 671 will be described assuming the first plate spring 403a. That is, the leaf spring 671 described in FIGS. 1 to 9 is configured as the first leaf spring 403a. FIG. 14 is a perspective view of the lighting fixture. FIG. 15 is an explanatory diagram of the arrangement of leaf springs for fixing the lighting apparatus of FIG. 14 to the ceiling. This luminaire comprises a lamp case 401 (hereinafter referred to as case 401) that houses the lamp inside and emits light from the light outlet 401 a, and constitutes the outer periphery of the light outlet 401 a of the case 401 to be attached. A ceiling mounting member that engages with the opening periphery of the ceiling. The case 401 is a cylindrical body whose inner side is configured as a light reflecting surface, and its outer shape is basically symmetrical with respect to the central axis of the case 401 orthogonal to the plane forming the light exit 401a. Note that the case 401 is not limited to a cylindrical shape, and may have another shape such as a spheroid or hemispherical shape.

天井取付部材は、ケース４０１の光出口４０１ａの先端部外周に配置された枠（または枠体）４０２と、この枠４０２からケース４０１の側面（外側壁面）４０１ｂ方向へ斜めに延びて天井の開口部周縁と弾性力を利用して係合可能な板バネとからなる。なお、ケース４０１と枠４０２とは一体成形で形成してもよい。 The ceiling mounting member includes a frame (or frame body) 402 disposed on the outer periphery of the distal end portion of the light outlet 401a of the case 401, and an opening in the ceiling extending obliquely from the frame 402 toward the side surface (outer wall surface) 401b of the case 401. It consists of a leaf | plate spring which can be engaged using a peripheral edge and elastic force. The case 401 and the frame 402 may be formed by integral molding.

板バネは、一対の第１板バネ４０３ａ，４０３ａと、第１板バネ４０３ａより長さの短い一対の第２板バネ４０３ｂ，４０３ｂとからなる。第１板バネ４０３ａ，４０３ａはケース４０１を挟んで対向配置され、第２板バネ４０３ｂ，４０３ｂは第１板バネ４０３ａ，４０３ａが対向する方向とほぼ直交する方向にケース４０１を挟んで対向配置されている。すなわち、ケース４０１の光出口４０１ａ方向から見た各板バネの配置は図１５に示すようになっている。第２板バネ４０３ｂの長さは、第１板バネ４０３ａより少なくとも天井の板厚分は短くするものとし、第１板バネ４０３ａの１／２程度とするのが好ましく、第１板バネ４０３ａの１／３程度とするのがより好ましい。このような板バネの長さの相違により、照明器具を天井に取り付ける際の操作性（または取扱性）が向上するからである。なお、ここでは第１板バネ４０３ａおよび第２板バネ４０３ｂの枠４０２側を根本部４０３ａｒ，４０３ｂｒとし、第１板バネ４０３ａおよび第２板バネ４０３ｂの開放端側を先端部４０３ａｔ，４０３ｂｔとし、第１板バネ４０３ａの先端部４０３ａｔには天井の開口部周縁に引掛り可能な折曲部を設けている。 The leaf spring includes a pair of first leaf springs 403a and 403a and a pair of second leaf springs 403b and 403b having a length shorter than that of the first leaf spring 403a. The first plate springs 403a and 403a are arranged opposite to each other with the case 401 interposed therebetween, and the second plate springs 403b and 403b are arranged to face each other with the case 401 interposed therebetween in a direction substantially orthogonal to the direction in which the first plate springs 403a and 403a face each other. ing. That is, the arrangement of the leaf springs as seen from the light exit 401a direction of the case 401 is as shown in FIG. The length of the second leaf spring 403b should be at least the plate thickness of the ceiling shorter than that of the first leaf spring 403a, and is preferably about ½ of the first leaf spring 403a. More preferably, about 1/3. This is because the difference in the length of the leaf springs improves the operability (or handleability) when attaching the lighting fixture to the ceiling. Here, the frame 402 side of the first plate spring 403a and the second plate spring 403b are the root portions 403ar and 403br, and the open end sides of the first plate spring 403a and the second plate spring 403b are the tip portions 403at and 403bt, A bent portion that can be hooked around the periphery of the opening of the ceiling is provided at the tip 403at of the first leaf spring 403a.

また、ケース４０１の光出口４０１ａと反対側の上部からは天板４０５がケース４０１の中心軸方向と略直交する方向に延ばされ、その天板４０５には、ランプの電流制御を行う安定器４０６や電源端子台４０７が搭載されている。 A top plate 405 extends from the upper portion of the case 401 opposite to the light outlet 401a in a direction substantially orthogonal to the central axis direction of the case 401. The top plate 405 includes a ballast that controls the current of the lamp. 406 and a power terminal block 407 are mounted.

図１６は、照明器具の天井への取付方法を示す図である。図１６を参照して、照明器具の天井への取付方法を説明する。まず、第１板バネ４０３ａ，４０３ａを操作しながら安定器４０６およびケース４０１を第１板バネ４０３ａ，４０３ａとともに天井４０８の開口部４０９から天井裏へ挿入し、第１板バネ４０３ａ，４０３ａの先端部（折曲部）４０３ａｔを天井４０８の開口部４０９周縁に掛止させて、照明器具を仮止めする（図１６（ａ））。続いて、第２板バネ４０３ｂ，４０３ｂを操作しながら安定器４０６およびケース４０１を第１板バネ４０３ａ，４０３ａおよび第２板バネ４０３ｂ，４０３ｂとともに天井４０８の開口部４０９内へ更に挿入し、枠４０２が天井４０８の開口部４０９周縁に届くまで押し込む（図１６（ｂ））。こうすることで、第１板バネ４０３ａ，４０３ａおよび第２板バネ４０３ｂ，４０３ｂの根本部４０３ａｒ，４０３ｂｒがその弾性力により開口部４０９周縁の内面を押し広げるよう開口部４０９の周縁に当たって係合し、照明器具が天井４０８に固定される（図１６（ｃ））。 FIG. 16 is a diagram illustrating a method of attaching the lighting fixture to the ceiling. With reference to FIG. 16, the attachment method to the ceiling of a lighting fixture is demonstrated. First, while operating the first leaf springs 403a and 403a, the ballast 406 and the case 401 are inserted into the ceiling from the opening 409 of the ceiling 408 together with the first leaf springs 403a and 403a, and the tips of the first leaf springs 403a and 403a are inserted. A part (folded part) 403at is hooked around the periphery of the opening 409 of the ceiling 408 to temporarily fix the lighting fixture (FIG. 16A). Subsequently, the ballast 406 and the case 401 are further inserted into the opening 409 of the ceiling 408 together with the first plate springs 403a and 403a and the second plate springs 403b and 403b while operating the second plate springs 403b and 403b. It pushes in until 402 reaches the periphery of the opening 409 of the ceiling 408 (FIG. 16B). By doing so, the base portions 403ar and 403br of the first leaf springs 403a and 403a and the second leaf springs 403b and 403b abut against the periphery of the opening 409 so as to push the inner surface of the periphery of the opening 409 by the elastic force. The lighting fixture is fixed to the ceiling 408 (FIG. 16C).

次に、図１７〜図２０を参照して、止め具６７２の別のバリエーション（本体取り付けバネ１８０）を説明する。以下の図１７〜図２０の説明では、止め具６７２の代替となる本体取り付けバネ１８０、及び本体取り付けバネ１８０に関係する本体取付け開口部１１３、取り付けバネ当接部１１４等の要素についてのみ説明する。図１０〜図１３では、Ｖ型バネ５０５によって下方に付勢される押え金具５０６を有する取付装置５０３を説明した。以下の図１７〜図２０では、止め具６７２に相当する要素として、本体取り付けバネ１８０を説明する。以下では本体取り付けバネ１８０が照明器具８００に使用される場合を説明するが、図１〜図９で説明した照明器具６００に本体取り付けバネ１８０が使用される場合、照明器具６００は、以下に説明する機器本体１１０（図１８）、本体取付け開口部１１３（図１８）、取り付けバネ当接部１１４（図１８）等の要素を有することになる。本体取り付けバネ１８０は、機器本体１１０を取り付け面に固定するための部品である。後述のように、二つの本体取り付けバネ１８０は、機器本体１１０の外側の互いに対称な位置に取り付けられる。 Next, another variation (main body attaching spring 180) of the stopper 672 will be described with reference to FIGS.

図２０は、機器本体１１０を示す正面図及びＢ−Ｂ端面図（一部）及び破断背面図である。本体取付け開口部１１３の上端付近の幅Ｗ_３は、本体取り付けバネ１８０の二つの翼部１８６間の長さより長く、本体取り付けバネ１８０の先端を、機器本体１１０の外から内へ挿入することができる。本体取付け開口部１１３の下側の幅Ｗ_４は、本体取り付けバネ１８０の中央接続部１８１の幅よりもわずかに狭く、本体取り付けバネ１８０の先端を挿入すると、本体取り付けバネ１８０がわずかに変形し、板バネの応力で本体取り付けバネ１８０が固定される。本体取り付けバネ１８０の開口挿入部１８３の下端と、機器本体１１０の鍔部１１５との間に取り付け面を挟み込む位置に、本体取り付けバネ１８０を固定する。このとき、本体取り付けバネ１８０の押さえ爪部１８４と、裏面押さえ部１８５との間に、機器本体１１０の取り付けバネ当接部１１４が挟まれている。機器本体１１０が下方向に動こうとすると、押さえ爪部１８４を下に曲げようとする力が働くので、押さえ爪部１８４と裏面押さえ部１８５との間隔が狭くなり、取り付けバネ当接部１１４を強く挟み込み、機器本体１１０が動くのを防ぐ。 FIG. 20 is a front view, a BB end view (part), and a broken rear view showing the device main body 110. The width W ₃ near the upper end of the body attachment opening 113 is longer than the length between the two wings 186 of the body attachment spring 180, and the tip of the body attachment spring 180 can be inserted from the outside of the device body 110 into the inside. it can. Width W of the lower body mounting opening 113 ₄ is slightly narrower than the width of the central connection portion 181 of the main body mounting spring 180, inserting a tip of the main body mounting spring 180 deforms slightly body mounting spring 180 The body attachment spring 180 is fixed by the stress of the leaf spring. The body attachment spring 180 is fixed at a position where the attachment surface is sandwiched between the lower end of the opening insertion portion 183 of the body attachment spring 180 and the flange 115 of the device body 110. At this time, the attachment spring abutting portion 114 of the device main body 110 is sandwiched between the pressing claw portion 184 of the main body attachment spring 180 and the back surface pressing portion 185. When the device main body 110 tries to move downward, a force to bend the pressing claw portion 184 is applied, so that the interval between the pressing claw portion 184 and the back surface pressing portion 185 is narrowed, and the attachment spring contact portion 114. To prevent the device main body 110 from moving.

本体取り付けバネ１８０が取り付けられる位置は、枠取付けバネ２１０の輪部２１１の上、二つの腕部２１２の間の位置になる。したがって、本体取り付けバネ１８０と枠取付けバネ２１０とは干渉することはない。 The position where the main body attachment spring 180 is attached is a position between the two arm portions 212 on the ring portion 211 of the frame attachment spring 210. Therefore, the main body mounting spring 180 and the frame mounting spring 210 do not interfere with each other.

以上、図３、図８等に示したように、照明器具６００が、３つの板バネ６７１、及び３つの止め具６７２を備える構成を説明した。板バネ６７１、止め具６７２の個数としては各３個が好ましいが、限定するものではない。各個数は、照明器具の大きさや重量等によって適宜、変更することができる。
図２１は、照明器具６００の上面図を単純化した図であるが、（ａ）のように各２個（９０度おき）でもよいし、（ｂ）のように各４個（４５度おき）でもよい。 As described above, as illustrated in FIGS. 3 and 8, the configuration in which the lighting fixture 600 includes the three leaf springs 671 and the three stoppers 672 has been described. The number of leaf springs 671 and stoppers 672 is preferably three, but is not limited. Each number can be appropriately changed depending on the size and weight of the lighting fixture.
FIG. 21 is a simplified top view of the luminaire 600, but it may be two pieces (every 90 degrees) as shown in (a), or four pieces (every 45 degrees) as shown in (b). )

実施の形態１の照明器具６００では、３組の止め具６７２と、３組の板バネ６７１とを、化粧枠６７６の周囲に上面矢視でみて交互に６０度間隔で配置する構成とした。この構成によって、照明器具６００は取り付け作業性が良好であり、また天井面に確実に取り付けることが可能となる。また、照明器具６００の前記構成によって、放熱部６１０の大型化に伴い照明器具６００の重量が増大した場合にも、上下方向及び水平方向の動きを、簡易な構成で拘束することができる。照明器具６００の前記構成は、放熱部６１０に起因する重量増加に限らず、電源装置に起因する重量増加など、あらゆる重量増加に対して適用できる。 The lighting fixture 600 of Embodiment 1 has a configuration in which three sets of stoppers 672 and three sets of leaf springs 671 are alternately arranged around the decorative frame 676 at intervals of 60 degrees as viewed from above. With this configuration, the luminaire 600 has good workability and can be securely attached to the ceiling surface. In addition, with the configuration of the lighting fixture 600, even when the weight of the lighting fixture 600 increases with an increase in the size of the heat radiating unit 610, the vertical and horizontal movements can be constrained with a simple configuration. The said structure of the lighting fixture 600 is applicable not only to the weight increase resulting from the thermal radiation part 610 but to all weight increases, such as the weight increase resulting from a power supply device.
