Description

この発明は照明器具の光源部を本体に取り付ける構造に関する。 The present invention relates to a structure for attaching a light source part of a lighting fixture to a main body.

近年、蛍光灯用照明器具に変わって、ＬＥＤを光源とした照明器具が使用されている。ＬＥＤを使用している照明器具は、従来の蛍光灯用照明器具と同じように、蛍光灯の変わりとしてＬＥＤを備えた光源部が天井などの被取付面に固定された本体部に、脱着可能に固定されているものがある。 In recent years, lighting fixtures using LEDs as light sources have been used instead of fluorescent lighting fixtures. Lighting fixtures that use LEDs can be attached to and detached from the main body, where the light source with LEDs is fixed to the mounting surface, such as the ceiling, in place of fluorescent lamps, just like conventional fluorescent lighting fixtures. There is something fixed to.

それらの光源部と本体部の取付方法は、光源部が本体部に設けられた窪みに挿入されて取り付けられる照明器具であって、光源部の側面に設けられたバネ部材が弾性変形しながら窪みに挿入され、窪み内部に設けられ光源部を固定する金具と係合し、光源部と本体部は連結されるものがある（例えば、特許文献１）。 The light source part and the main body part are attached by a lighting fixture in which the light source part is inserted and attached to a recess provided in the main body part, and the spring member provided on the side surface of the light source part is depressed while elastically deforming. The light source part and the main body part are connected to each other by engaging with a metal fitting that is inserted in the recess and is provided inside the recess and fixes the light source part (for example, Patent Document 1).

また、点灯装置を備えた光源部が本体部に取付られたものもあり、点灯装置を備えた光源部の側面全長には溝部が形成され、本体部には光源部溝部全長と係合する爪部が設けられており、側面全長で係合することで、光源部の重量負荷を分散化し、爪部の変形防止を行なっているものもある（例えば、特許文献２）。 In addition, there is a light source unit provided with a lighting device attached to the main body, a groove is formed in the entire length of the side surface of the light source unit provided with the lighting device, and a claw that engages with the total length of the light source unit groove in the main body. In some cases, the weight load of the light source part is dispersed and the claw part is prevented from being deformed by engaging the entire length of the side surface (for example, Patent Document 2).

また、本体部の側面と、光源部の側面に嵌合部が設けられており、嵌合部が回動の中心となり、光源部が本体部内部に向かって回動し取り付けられるものがある（例えば、特許文献３）。 In addition, a fitting portion is provided on a side surface of the main body portion and a side surface of the light source portion, and the fitting portion serves as a center of rotation, and the light source portion is rotated and attached toward the inside of the main body portion ( For example, Patent Document 3).

特開２０１３−８０５９２号公報JP2013-80592A 国際公開２０１０／０９５７１０号公報International Publication No. 2010/095710 特開２０１１−０６０７１８号公報JP 2011-060718 A

しかしながら、特許文献１の照明器具は複数のバネ部材により光源部と本体部は連結されており、複数のバネ部材を同時に対応する固定金具に差し込まないとバネ部、もしくは光源部に応力がかかり、変形及び故障の原因の可能性がある。 However, in the lighting apparatus of Patent Document 1, the light source unit and the main body unit are connected by a plurality of spring members, and stress is applied to the spring unit or the light source unit unless the plurality of spring members are simultaneously inserted into the corresponding fixtures. There is a possibility of causing deformation and failure.

また、特許文献２の照明器具は、側面全長にて、溝部と爪部と嵌合している。その為、光源部を本体部から取り外すときは、嵌合した全長を同時に押圧し溝部と爪部の嵌合状態を解徐しなくていけなく、専用の治具が必要となると考えられる。 Moreover, the lighting fixture of patent document 2 is fitting with the groove part and the nail | claw part in the side surface full length. For this reason, when removing the light source part from the main body part, it is considered that the full length of the fitted part must be pressed at the same time to release the fitting state between the groove part and the claw part, and a dedicated jig is required.

また、特許文献３の照明器具は、回動できるよう嵌合形状にしている為、照明器具と天井の間には光源側面部が回転できるように隙間を設ける必要がある。また、嵌合部と対向する側面はねじにより固定しており、意匠性に影響があった。 Moreover, since the lighting fixture of patent document 3 is made into the fitting shape so that rotation is possible, it is necessary to provide a clearance gap between a lighting fixture and a ceiling so that a light source side surface part can rotate. Moreover, the side surface facing the fitting portion is fixed with screws, which has an influence on the design.

そこで本発明では、光源部と本体部が脱着可能な照明器具にて、光源部と本体部が簡単に連結することができるとともに、連結部が劣化しにくい連結機構、及びその連結機構を備えた照明器具を提供することを目的とする。 Therefore, in the present invention, a lighting device in which the light source part and the main body part are detachable can be easily connected to the light source part and the main body part, and the connection part is not easily deteriorated, and the connection mechanism is provided. It aims at providing a lighting fixture.

この発明の照明器具用取付バネは、
光源が保持されたユニット側保持部を有する光源ユニットの前記ユニット側保持部に配置され、前記光源ユニットを本体部に固定する照明器具用取付バネであって、
前記ユニット側保持部に取り付けられるバネ側保持部と、
前記バネ側保持部に接続し、前記光源ユニットが前記本体部に取り付けられている状態にある場合に、前記本体部に設けられた引掛部と係合して前記引掛部を前記ユニット側保持部の方向に押圧する押圧部と
を有することを特徴とする。 The mounting spring for lighting equipment of this invention is:
A mounting spring for a lighting fixture that is disposed in the unit side holding portion of the light source unit having a unit side holding portion in which a light source is held, and fixes the light source unit to the main body portion;
A spring side holding portion attached to the unit side holding portion;
When the light source unit is connected to the spring-side holding portion and is attached to the main body portion, the hook portion is engaged with the hook portion provided on the main body portion and the hook-side holding portion is connected to the unit-side holding portion. It has a pressing part which presses in the direction.

この発明によれば、光源部と本体部が脱着可能な照明器具において、光源部と本体部が簡単に連結でき、連結部が劣化しにくい連結機構を提供できる。 According to this invention, in the lighting fixture in which the light source part and the main body part are detachable, the light source part and the main body part can be easily connected, and a connection mechanism in which the connection part is hardly deteriorated can be provided.

次に、光源部２００の本体部１００への取付工程について説明する。図１６は本実施の形態１における光源部２００の本体部１００への取付工程図である。図１６のうち、（ａ）は、光源部２００が本体部１００に取り付けられる前の状態である。（ｂ）は、作業者が、光源部２００の線バネ２８０を本体部１００の引掛金具１１６の引掛孔１１６ａに差し込み、かつ、板バネ１３０の屈曲部Ｋ（引っ掛け部）を連結金具２５０のバネ挿入孔２５０ａ−１の縁に引っ掛けた状態である。（ｃ）は、作業者が、引掛孔１１６ａに差し込んだ線バネ２８０を回転の中心として、光源部２００を（ｂ）の状態から回転させた状態を示す。このとき板バネ１３０は連結金具２５０のバネ挿入孔２５０ａ−１の縁を摺動する。（ｄ）は、本体部１００に光源部２００が取り付けられた状態である。 Next, a process for attaching the light source unit 200 to the main body unit 100 will be described. FIG. 16 is a process diagram of attaching the light source unit 200 to the main body unit 100 according to the first embodiment. 16A shows a state before the light source unit 200 is attached to the main body unit 100. FIG. (B) shows that the operator inserts the wire spring 280 of the light source unit 200 into the hooking hole 116a of the hooking metal fitting 116 of the main body 100, and the bent portion K (hooking portion) of the leaf spring 130 is the spring of the connecting metal fitting 250. It is in a state of being hooked on the edge of the insertion hole 250a-1. (C) shows a state where the operator has rotated the light source unit 200 from the state (b) with the wire spring 280 inserted into the hooking hole 116a as the center of rotation. At this time, the leaf spring 130 slides on the edge of the spring insertion hole 250 a-1 of the connection fitting 250. (D) is a state in which the light source unit 200 is attached to the main body unit 100.

（（ａ）の状態）
図１６の（ａ）では、光源部２００と本体部１００は別々の状態である。また、本体部１００では、本体部１００の引掛孔１１６ａ（縁１１６ａ−１）と光源受部１１３ｂとの間の距離Ｂ（図６（ｂ））が、光源部２００の保持部２２０の上面と線バネ２８０の引掛摺動部２８０ｄとの距離Ａより大きくなるように形成されている。これについては後述する。 (State (a))
In FIG. 16A, the light source unit 200 and the main body unit 100 are in separate states. Further, in the main body 100, the distance B (FIG. 6B) between the hooking hole 116 a (edge 116 a-1) of the main body 100 and the light source receiver 113 b is the upper surface of the holding unit 220 of the light source 200. The wire spring 280 is formed to be larger than the distance A with the hooking sliding portion 280d. This will be described later.

（（ｂ）の状態）
次に図１６の（ｂ）では、作業者が、光源部２００の線バネ２８０を本体部１００の引掛金具１１６の引掛孔１１６ａに差し込んだ状態であり、板バネ１３０の屈曲部Ｋを連結金具２５０のバネ挿入孔２５０ａ−１の縁に引っ掛けた状態である。線バネ２８０では、先端の引掛摺動部２８０ｄが引掛孔１１６ａの縁１１６ａ−１上に当接しており、距離Ｂが距離Ａより広い為（Ｂ＞Ａ）、押圧部２８０ｃが引掛孔１１６ａの縁１１６ａ−１を押圧している状態である。なお距離Ａは図５の保持正面部２２０ａの上面から線バネ２８０の引掛摺動部２８０ｄの上方向の端部２８０ｄ−１までの距離である（図１４）。距離Ｂは、図６（ｂ），図１６（ｄ）のように本体部１００に光源部２００が装着されたときの、保持正面部２２０ａの上面（つまり、光源受部１１３ｂ）から、引掛孔１１６ａの縁１１６ａ−１までの距離である。 (State (b))
Next, in FIG. 16B, the operator has inserted the wire spring 280 of the light source unit 200 into the hooking hole 116a of the hooking metal 116 of the main body 100, and the bent portion K of the leaf spring 130 is connected to the connecting metal. This is a state of being hooked on the edge of 250 spring insertion holes 250a-1. In the wire spring 280, the hooking sliding portion 280d at the tip is in contact with the edge 116a-1 of the hooking hole 116a, and the distance B is wider than the distance A (B> A), so that the pressing portion 280c of the hooking hole 116a. The edge 116a-1 is being pressed. Note that the distance A is a distance from the upper surface of the holding front portion 220a in FIG. 5 to the upper end 280d-1 of the hooking sliding portion 280d of the wire spring 280 (FIG. 14). The distance B is a hooking hole from the upper surface of the holding front part 220a (that is, the light source receiving part 113b) when the light source part 200 is attached to the main body part 100 as shown in FIGS. 6 (b) and 16 (d). It is the distance to the edge 116a-1 of 116a.

板バネ１３０は、第２平坦部Ｌ２を取付部１１２に対する回転運動の回転中心として、円弧部Ｅが取付部１１２に対して垂直になるように弾性変形しながら回動する。また、板バネ１３０の屈曲部Ｋは、光源部２００の連結金具２５０のバネ挿入孔２５０ａ−１の縁に引っ掛けられている。 The leaf spring 130 rotates while being elastically deformed so that the arc portion E is perpendicular to the attachment portion 112 with the second flat portion L2 as the rotation center of the rotational movement with respect to the attachment portion 112. Further, the bent portion K of the leaf spring 130 is hooked on the edge of the spring insertion hole 250 a-1 of the connection fitting 250 of the light source unit 200.

なお、図１６の（ｂ）状態にて、吊りひも２９０のフック部２９０ｃは、本体部１００の吊孔１１２ｃに引っ掛けられる。また、作業者は、本体部１００の端子台コネクタ１２０ａと光源部２００の連結コネクタ２７０ｃを連結する。（なお、吊りひも２９０のフック部２９０ｃを吊孔１１２ｃに引っ掛けてから線バネ２８０を引掛孔１１６ａに挿入し、板バネ１３０をバネ挿入孔２５０ａ−１に挿入する手順としてもよい） In the state shown in FIG. 16B, the hook portion 290c of the suspension string 290 is hooked in the suspension hole 112c of the main body portion 100. In addition, the worker connects the terminal block connector 120 a of the main body unit 100 and the connection connector 270 c of the light source unit 200. (The procedure may be such that the hook 290c of the suspension string 290 is hooked on the suspension hole 112c, the wire spring 280 is inserted into the engagement hole 116a, and the leaf spring 130 is inserted into the spring insertion hole 250a-1).

（（ｃ）の状態）
次に、図１６の（ｃ）は、作業者が、引掛孔１１６ａに差し込んだ線バネ２８０を回転の中心として、光源部２００を（ｂ）の状態から回転させた状態を示す。板バネ１３０の円弧部Ｅの本体部１００側に位置する面が、バネ挿入孔２５０ａ−１の孔縁上をバネ復元力により摺動する。 (State (c))
Next, (c) of FIG. 16 shows a state in which the operator rotates the light source unit 200 from the state (b) with the wire spring 280 inserted into the hooking hole 116a as the center of rotation. The surface located on the main body 100 side of the circular arc portion E of the leaf spring 130 slides on the hole edge of the spring insertion hole 250a-1 by the spring restoring force.

板バネ１３０は円弧部Ｅが連結金具２５０のバネ挿入孔２５０ａ−１の縁を摺動する。他方の線バネ２８０は、作業者が線バネ２８０を中心として光源部２００を回転させる際、線バネ２８０では、引掛摺動部２８０ｄが引掛孔１１６ａの縁１１６ａ−１上を摺動しながら引掛孔１１６ａに挿し込まれる。作業者は、さらに光源部２００を回転させながら光源部２００の右側を本体部１００方向へ引き上げ、光源部２００の保持側面部２２０ｂおよび、カバー爪部２３０ａを本体部１００へ挿入する。このとき板バネ１３０は円弧部Ｅがバネ挿入孔２５０ａ−１の上側の縁を摺動する。 As for the leaf | plate spring 130, the circular arc part E slides the edge of the spring insertion hole 250a-1 of the connection metal fitting 250. FIG. The other wire spring 280 is hooked while the hooking sliding portion 280d slides on the edge 116a-1 of the hooking hole 116a when the operator rotates the light source unit 200 around the wire spring 280. It is inserted into the hole 116a. The operator further raises the right side of the light source unit 200 in the direction of the main body unit 100 while rotating the light source unit 200, and inserts the holding side surface unit 220 b and the cover claw unit 230 a of the light source unit 200 into the main body unit 100. At this time, in the leaf spring 130, the arc portion E slides on the upper edge of the spring insertion hole 250a-1.

なお、線バネ２８０は距離Ａが距離Ｂより狭い為、押圧部２８０ｃは弾性により変形しながら挿入されるとともに、引掛孔１１６ａおよび光源固定部１１３を線バネ２８０と光源蓋部２４０で押圧し把持している。 Since the wire spring 280 has a distance A shorter than the distance B, the pressing portion 280c is inserted while being elastically deformed, and the hooking hole 116a and the light source fixing portion 113 are pressed and held by the wire spring 280 and the light source lid portion 240. doing.

（（ｄ）の状態）
次に、図１６の（ｄ）において、作業者が、本本体部１００の光源受部１１３ｂと光源部２００のカバー当接部２３０ｂが当接するように光源部２００を本体部１００へ押し込むと、板バネ１３０の第３曲げ部が連結金具２５０のバネ受部２５０ａ−２と当接し、光源部２００は本体部１００に取り付けられる。このとき板バネ１３０は、光源部２００の装着状態が完了する直前では、第３曲げ部Ｍ３がバネ受部２５０ａ−２と当接し、円弧部Ｅの摺動が抑制される。そして作業者が光源部２００の本体部１００への差し込みを完了（光源部２００の装着完了）すると、板バネ１３０の第４曲げ部Ｍ４の内側箇所Ｍ４−１が、連結金具２５０のバネ挿入孔２５０ａ−１の上側の縁と押し合う状態で、この縁に対して位置決めされる。このとき、板バネ１３０が内側箇所Ｍ４−１（図１７）でバネ挿入孔２５０ａ−１の縁を支持する際のバネ定数は、図１６の（ｂ）において屈曲部Ｋで光源部２００を支持する際のバネ定数に対して著しく大きい。これは、板バネ１３０では第１平坦部Ｌ１（固定）が本体部１００に固定されるので、第１平坦部Ｌ１を固定端とする片持ち梁として大まかに見積もることができる。板バネ１３０では、ほとんど弾性変形しない第１曲げ部Ｍ１と第４曲げ部Ｍ４との直線距離（スパン）は、第１曲げ部Ｍ１と屈曲部Ｋとの距離（スパン）の、例えば１／５〜１／６程度である。片持ち梁ではスパンはバネ定数に３乗で影響する。よって、第４曲げ部Ｍ４におけるバネ定数は、１／５であれば屈曲部Ｋにおけるバネ定数の１２５倍であり、１／６であれば屈曲部Ｋにおけるバネ定数の２１６倍である。このため、作業者が光源部２００を本体部１００への差し込みを完了すると、板バネ１３０の第４曲げ部Ｍ４の内側箇所Ｍ４−１が、連結金具２５０のバネ挿入孔２５０ａ−１の上側の縁を支持できる。つまり第４曲げ部Ｍ４の内側箇所Ｍ４−１で、光源部２００の自重を支持することができる。
この（ｄ）の状態で線バネ２８０の下面２８０ｄ−１−１（図１４）は、図１６（ｄ）の矢印の方向に戻ろうとする復元力によって、縁１１６ａ−１を押圧している。 (State of (d))
Next, in FIG. 16D, when the operator pushes the light source unit 200 into the main body unit 100 so that the light source receiving unit 113b of the main body unit 100 and the cover contact unit 230b of the light source unit 200 are in contact with each other. The third bent portion of the leaf spring 130 contacts the spring receiving portion 250 a-2 of the connection fitting 250, and the light source portion 200 is attached to the main body portion 100. At this time, immediately before the mounting state of the light source unit 200 is completed, the leaf spring 130 comes into contact with the spring receiving portion 250a-2, and the sliding of the arc portion E is suppressed. When the operator completes the insertion of the light source unit 200 into the main body unit 100 (the mounting of the light source unit 200 is completed), the inner portion M4-1 of the fourth bent portion M4 of the leaf spring 130 is the spring insertion hole of the connection fitting 250. Positioned against this edge, pressing against the upper edge of 250a-1. At this time, the spring constant when the leaf spring 130 supports the edge of the spring insertion hole 250a-1 at the inner portion M4-1 (FIG. 17) is that the light source unit 200 is supported by the bent portion K in FIG. It is remarkably large with respect to the spring constant. This can be roughly estimated as a cantilever having the first flat portion L1 as a fixed end because the first flat portion L1 (fixed) is fixed to the main body 100 in the leaf spring 130. In the leaf spring 130, the linear distance (span) between the first bent part M1 and the fourth bent part M4 that hardly elastically deforms is, for example, 1/5 of the distance (span) between the first bent part M1 and the bent part K. About 1/6. In cantilever beams, the span affects the spring constant by the third power. Therefore, if the spring constant in the fourth bent portion M4 is 1/5, it is 125 times the spring constant in the bent portion K, and if it is 1/6, it is 216 times the spring constant in the bent portion K. For this reason, when the operator completes the insertion of the light source unit 200 into the main body unit 100, the inner portion M4-1 of the fourth bent portion M4 of the leaf spring 130 is located above the spring insertion hole 250a-1 of the connection fitting 250. Can support the edge. That is, the weight of the light source unit 200 can be supported by the inner portion M4-1 of the fourth bending portion M4.
In this state (d), the lower surface 280d-1-1 (FIG. 14) of the wire spring 280 presses the edge 116a-1 by a restoring force to return in the direction of the arrow in FIG. 16 (d).

（取り外し方法）
次に、光源部２００を本体部１００から取り外す方法について説明する。光源部２００の取り外し方法は、取り付け方法の逆の手順になる。
（１）まず、作業者は図１６の（ｄ）の光源部２００が本体部１００が取り付けられた状態から、板バネ１３０が設置されている側を下方向に引き下げる。
（２）次に、作業者は光源部２００を図１６の（ｂ）の状態まで引き下げたら、端子台コネクタ１２０ａと連結コネクタ２７０ｃとの連結を解徐し、吊りひも２９０のフック部２９０ｃを本体部１００の吊孔１１２ｃからはずし、その後、板バネ１３０の屈曲部Ｋを連結金具２５０のバネ挿入孔２５０ａ−１から外す。（なお、吊りひも２９０のフック部２９０ｃは線バネ２８０を引掛金具１１６から外した後に吊孔１１２ｃから外すようにしてもよい）
（３）最後に、作業者は光源部２００を引掛金具１１６から挿し込みした方向と反対方向へ線バネ２８０を引き抜き、光源部２００を本体部１００から取り外す。 (How to remove)
Next, a method for removing the light source unit 200 from the main body unit 100 will be described. The method for removing the light source unit 200 is the reverse of the attaching method.
(1) First, the operator pulls down the side on which the leaf spring 130 is installed from the state in which the light source unit 200 in FIG.
(2) Next, when the operator lowers the light source unit 200 to the state shown in FIG. 16B, the connection between the terminal block connector 120a and the connection connector 270c is released, and the hook portion 290c of the hanging strap 290 is moved to the main body. Then, the bent portion K of the leaf spring 130 is removed from the spring insertion hole 250 a-1 of the connection fitting 250. (The hook portion 290c of the hanging cord 290 may be removed from the hanging hole 112c after the wire spring 280 is removed from the hook fitting 116).
(3) Finally, the operator pulls out the wire spring 280 in the direction opposite to the direction in which the light source unit 200 is inserted from the hook metal fitting 116, and removes the light source unit 200 from the main body unit 100.

次に、取付時における、板バネ１３０の弾性作用（作用効果）に関して説明をする。図１７は、本実施の形態１の取付時における、板バネ１３０の第２平坦部Ｌ２（可動軸）の周辺の拡大図である。図１７において、点線は弾性変形していない状態（図１６の（ａ）の状態）の板バネ１３０（板バネ１３０ａとする）を示し、実線は内側箇所Ｍ４−１で光源部２００を保持している弾性変形状態（図１６の（ｄ）の状態）の板バネ１３０（板バネ１３０ｂとする）を示している。 Next, the elastic action (action effect) of the leaf spring 130 at the time of attachment will be described. FIG. 17 is an enlarged view around the second flat portion L2 (movable shaft) of the leaf spring 130 when the first embodiment is attached. In FIG. 17, the dotted line indicates the leaf spring 130 (referred to as the leaf spring 130 a) in a state where it is not elastically deformed (the state of FIG. 16 (a)), and the solid line holds the light source unit 200 at the inner portion M <b> 4-1. A leaf spring 130 (referred to as a leaf spring 130b) in an elastically deformed state (state shown in FIG. 16D) is shown.

図１７において、板バネ１３０ｂ（実線）では、内側箇所Ｍ４−１（黒丸で示した）が、板バネ１３０ａ（点線）の内側箇所Ｍ４−１相当箇所（板バネ１３０ｂ（実線）で内側箇所Ｍ４−１に印をつけて板バネ１３０ａ（点線）の状態に戻したときの印の位置）と比較すると、以下の様である。つまり板バネ１３０ｂ（実線）は、第１平坦部Ｌ１の方向へ水平に寸法Ａ、下側方向に寸法Ｂだけ弾性変形した状態で、光源部２００（連結金具２５０）を保持している。 In FIG. 17, in the leaf spring 130b (solid line), the inner portion M4-1 (shown by a black circle) is the portion corresponding to the inner portion M4-1 of the leaf spring 130a (dotted line) (the leaf spring 130b (solid line) and the inner portion M4). When compared with the position of the mark -1 when the plate spring 130a (dotted line) is returned to the mark, the following is shown. That is, the leaf spring 130b (solid line) holds the light source unit 200 (the coupling metal 250) in a state where it is elastically deformed by the dimension A horizontally in the direction of the first flat portion L1 and the dimension B in the lower direction.

（板バネ１３０のへたりと弾性力との関係）
板バネ１３０は図１６の（ｂ）のように使用される。よってへたりが生じると図６における第２角度θ３が大きくなる方向に影響するが、この影響は図１７において寸法Ａが増加する方向に働き、結果としてへたりが生じた際の板バネ１３０が光源部２００（連結金具２５０）を支持する弾性力の低下を抑制できる。このように、板バネ１３０の形状的特徴によって、板バネ１３０に劣化（へたり）が発生しても、弾性力の低下をもたらすことなく（へたりにより、むしろ弾性力（たわみ）が増加する）、光源部２００を保持できる効果を有する。なお、連結金具２５０は板バネ１３０と連結するものであり、寸法Ａ、寸法Ｂがマイナスにならないものであれば、本実施の形態１以外の形状のものでも良い。 (Relationship between leaf spring 130 sag and elastic force)
The leaf spring 130 is used as shown in FIG. Therefore, when a sag occurs, it affects the direction in which the second angle θ3 in FIG. 6 increases, but this effect acts in the direction in which the dimension A increases in FIG. 17, resulting in the leaf spring 130 when the sag occurs. It is possible to suppress a decrease in elastic force that supports the light source unit 200 (the connecting metal fitting 250). Thus, even if the leaf spring 130 is deteriorated (sagging) due to the shape characteristics of the leaf spring 130, the elastic force (deflection) is increased without causing a decrease in the elastic force. ), The light source unit 200 can be held. The connecting metal fitting 250 is connected to the leaf spring 130 and may have a shape other than the first embodiment as long as the dimension A and the dimension B do not become negative.

本実施の形態は、光源部２００に設けられ本体部１００の引掛金具に挿入されるとともに本体部１００の一部を把持する線バネ２８０と、本体部１００に設けられ光源部２００に設けられた連結金具２５０を摺動し光源部２００を引き上げる板バネ１３０により、本体部１００と光源部２００が確実に、かつ簡単に連結される連結機構、及びその連結機構を備えた照明器具を提供することができる。 In the present embodiment, a linear spring 280 that is provided in the light source unit 200 and is inserted into a hook metal fitting of the main body unit 100 and grips a part of the main body unit 100, and the light source unit 200 provided in the main body unit 100.
