Description

本発明は、板バネを用いて造営材に取り付けられる照明器具に関する。   The present invention relates to a lighting fixture attached to a construction material using a leaf spring.

従来、照明器具として、例えば、ダウンライトのように天井板等の造営材に埋め込み配設されて鉛直方向下向きに光を出射する天井埋込型の照明器具等が知られている。   2. Description of the Related Art Conventionally, as a lighting fixture, for example, a ceiling-embedded lighting fixture that is embedded in a construction material such as a ceiling board and emits light downward in the vertical direction is known.

この種の照明器具は、光源と、光源が取り付けられる器具本体と、造営材に形成された取付穴の周縁に配置される環状の固定枠と、一端が固定枠に取り付けられた複数の板バネとを備える(例えば特許文献1など参照)。特許文献1に記載された照明器具は、固定枠(及び造営材)に対する器具本体の取り付け角度、すなわち、光軸の方向を変えることができる、いわゆるユニバーサルダウンライトである。   This type of lighting fixture includes a light source, a fixture main body to which the light source is attached, an annular fixed frame disposed at the periphery of the attachment hole formed in the construction material, and a plurality of leaf springs having one end attached to the fixed frame. (See, for example, Patent Document 1). The lighting fixture described in Patent Document 1 is a so-called universal downlight that can change the mounting angle of the fixture body with respect to the fixed frame (and the construction material), that is, the direction of the optical axis.

特許文献1に記載された照明器具においては、各板バネが二つの円弧部を有し、器具本体に近い側の円弧部を器具本体に近づく向きに弾性変形させて造営材に当接させる。これにより、板バネが造営材を押す力が働く。特許文献1に記載された照明器具においては、この力を用いて照明器具を造営材に固定している。板バネの二つの円弧部を接続する部分は、折り曲げられ、板バネの固定されていない側の端部(以下、「自由端」とも呼ぶ。)は鉛直方向下向きに向けられる。これにより、照明器具の光軸の方向を変えるために器具本体の造営材に対する角度を変える場合に、板バネと器具本体とが干渉することを抑制できる。   In the lighting fixture described in Patent Document 1, each leaf spring has two arc portions, and the arc portion on the side close to the fixture main body is elastically deformed so as to approach the fixture main body and is brought into contact with the construction material. Thereby, the force which a leaf | plate spring presses a construction material works. In the lighting fixture described in Patent Document 1, the lighting fixture is fixed to the construction material using this force. A portion connecting the two arc portions of the leaf spring is bent, and an end portion of the leaf spring on which the leaf spring is not fixed (hereinafter also referred to as “free end”) is directed downward in the vertical direction. Thereby, when changing the angle with respect to the construction material of an instrument main body in order to change the direction of the optical axis of a lighting fixture, it can suppress that a leaf | plate spring and an instrument main body interfere.

特開2015−135743号公報JP2015-135743A

特許文献1に記載されたような照明器具を造営材に取り付ける際には、まず、造営材に形成された取付穴に、器具本体とともに板バネの自由端を挿入する。板バネの自由端を取付穴に挿入する際には、自由端が造営材と干渉することを抑制するために、板バネを変形させることによって、自由端を器具本体の側面に近づける。ここで、板バネの自由端を鉛直方向下向きに向けるように二つの円弧部を接続する部分が折り曲げられていることから、板バネの自由端を器具本体側に向けて変形させるには、二つの円弧部を接続する部分の折り曲げ角を拡げる向きに力を加える必要がある。しかしながら、この場合、当該力が大きいため、板バネを変形させる力が働いていないときの円弧部の湾曲の向きと逆向きに、円弧部が湾曲させられる。これにより、照明器具を造営材に取り付ける際に、円弧部が塑性変形する場合がある。このため、照明器具を取り付けた際に板バネの円弧部が造営材を押す力が低下し得る。   When attaching a lighting fixture as described in Patent Document 1 to a construction material, first, the free end of the leaf spring is inserted into the attachment hole formed in the construction material together with the equipment body. When the free end of the leaf spring is inserted into the mounting hole, the free end is brought closer to the side surface of the instrument body by deforming the leaf spring in order to prevent the free end from interfering with the construction material. Here, since the portion connecting the two arc portions is bent so that the free end of the leaf spring is directed vertically downward, in order to deform the free end of the leaf spring toward the instrument body side, It is necessary to apply a force in the direction that widens the bending angle of the portion connecting the two arc portions. However, in this case, since the force is large, the arc portion is bent in a direction opposite to the bending direction of the arc portion when the force for deforming the leaf spring is not working. Thereby, when attaching a lighting fixture to a construction material, an arc part may deform plastically. For this reason, when attaching a lighting fixture, the force which the circular arc part of a leaf | plate spring presses a construction material may fall.

そこで、本発明は、造営材に形成された取付穴に板バネを用いて取り付けられる照明器具であって、取り付けの際に生じる板バネの塑性変形を抑制できる照明器具を提供することを目的とする。   Therefore, the present invention aims to provide a lighting fixture that can be attached to a mounting hole formed in a construction material using a leaf spring, and that can suppress plastic deformation of the leaf spring that occurs during attachment. To do.

図4及び図5に示されるように、板バネ80は、取付板部88と、第一板部81と、第二板部82と、接続部83と、爪状部87とを備える。   As shown in FIGS. 4 and 5, the leaf spring 80 includes an attachment plate portion 88, a first plate portion 81, a second plate portion 82, a connection portion 83, and a claw-like portion 87.

取付板部88は、板バネ80の二つの端部のうち、固定枠30に固定される側の端部である。本実施の形態では、図4に示されるように、取付板部88は、平板状の形状を有し、図1に示されるボルト38を挿入するための貫通孔が形成されている。ボルト38を、当該貫通孔を介して固定枠30に形成されたねじ穴に捻じ込むことによって、取付板部88が固定枠30に固定される。第一板部81は、造営材の取付穴に当接される部分であり、板バネ80の取付板部88と接続部83との間に位置する。本実施の形態では、第一板部81は、湾曲形状を有する。より詳しくは、図5に示される第一板部81の長手方向の側面形状が円弧状となるように第一板部81が曲げられている。これにより、照明器具10を造営材に形成された取付穴に取り付ける際に、第一板部81を弾性変形させた状態で造営材の取付穴の角部に当接させることができる。したがって、第一板部81が造営材を押す力によって、照明器具10が取付穴から離脱することを抑制できる。なお、第一板部81は、単一の曲率半径で湾曲していなくてもよい。つまり、第一板部81の位置に応じて曲率半径が異なってもよい。第一板部81の湾曲形状の曲率半径は、照明器具10の重量、板バネ80の材質及び板厚、造営材の厚さなどに応じて適宜設定されればよい。第一板部81の湾曲形状の曲率半径は、例えば25mm程度である。第一板部81の湾曲形状の曲率半径は、例えば、10mm以上100mm以下程度であってもよい。   The attachment plate portion 88 is an end portion on the side fixed to the fixed frame 30 among the two end portions of the leaf spring 80. In the present embodiment, as shown in FIG. 4, the mounting plate portion 88 has a flat plate shape, and a through hole for inserting the bolt 38 shown in FIG. 1 is formed. The mounting plate 88 is fixed to the fixed frame 30 by screwing the bolts 38 into the screw holes formed in the fixed frame 30 through the through holes. The first plate portion 81 is a portion that comes into contact with the attachment hole of the construction material, and is located between the attachment plate portion 88 of the leaf spring 80 and the connection portion 83. In the present embodiment, the first plate portion 81 has a curved shape. More specifically, the first plate portion 81 is bent so that the side surface shape in the longitudinal direction of the first plate portion 81 shown in FIG. Thereby, when attaching the lighting fixture 10 to the attachment hole formed in the construction material, it can be made to contact | abut to the corner | angular part of the attachment hole of the construction material in the state which elastically deformed the 1st board part 81. FIG. Therefore, it can suppress that the lighting fixture 10 leaves | separates from an attachment hole with the force in which the 1st board part 81 pushes a construction material. Note that the first plate portion 81 may not be curved with a single curvature radius. That is, the radius of curvature may be different depending on the position of the first plate portion 81. The curvature radius of the curved shape of the first plate portion 81 may be appropriately set according to the weight of the lighting fixture 10, the material and plate thickness of the leaf spring 80, the thickness of the construction material, and the like. The curvature radius of the curved shape of the first plate portion 81 is, for example, about 25 mm. The curvature radius of the curved shape of the first plate portion 81 may be, for example, about 10 mm or more and 100 mm or less.

第二板部82は、接続部83を介して第一板部81に接続される部分である。本実施の形態では、第二板部82は、平板状の形状を有する。つまり、図5に示されるように長手方向の側面の形状が直線状である。   The second plate portion 82 is a portion connected to the first plate portion 81 via the connection portion 83. In the present embodiment, the second plate portion 82 has a flat shape. That is, as shown in FIG. 5, the shape of the side surface in the longitudinal direction is linear.

接続部83は、第一板部81及び第二板部82を接続し、屈曲形状を有する部分である。なお、ここで、「屈曲形状」は、曲げられた形状であることを意味し、所定の曲率半径で湾曲した形状、及び、曲率半径を有さない折り曲げ形状の両方を含む。本実施の形態では、接続部83には、接続部83を厚さ方向に貫通する開口部84が形成されている。これにより、接続部83における板幅(板バネ80の長手方向に垂直な方向の幅)を実質的に低減することができるため、接続部83を変形させるために要する力を低減できる。本実施の形態では、開口部84は、板バネ80の長手方向に沿って延びる長辺84aと、長手方向に対して垂直方向に延びる短辺84bを有する角穴である。これにより、接続部83の長手方向の各位置における全幅が一定である場合、接続部83における実質的な板幅(つまり、板幅から開口部84の幅を除いた長さ)を板バネ80の長手方向において略一定とすることができるため、接続部83を変形させる際に、接続部83の長手方向の各位置における変形量をほぼ一様にすることができる。つまり、接続部83が局所的に変形することを抑制できる。さらに、接続部83は、第一板部81の湾曲形状の曲率半径より小さい曲率半径で屈曲されている。言い換えると、接続部83は、第一板部81の湾曲形状の曲率(つまり、曲率半径の逆数)より大きい曲率で屈曲されている。さらに言い換えると、接続部83は、第一板部81から第二板部82まで滑らかに湾曲した形状を有する。このように、所定の曲率半径で接続部83が屈曲されていることにより、接続部83が折り曲げられている場合より、屈曲された接続部83を直線状に近づける向きに変形させるために要する力を低減できる。接続部83の曲率半径は、特に限定されないが、板バネ80の板厚より大きければよい。板バネの板厚は、特に限定されないが、例えば0.4mm程度である。本実施の形態では、接続部83の曲率半径は、10mm程度である。   The connection part 83 is a part which connects the 1st board part 81 and the 2nd board part 82, and has a bending shape. Here, “bent shape” means a bent shape, and includes both a shape curved with a predetermined radius of curvature and a bent shape having no radius of curvature. In the present embodiment, the connecting portion 83 is formed with an opening 84 that penetrates the connecting portion 83 in the thickness direction. Thereby, since the plate width (width in the direction perpendicular to the longitudinal direction of the leaf spring 80) at the connection portion 83 can be substantially reduced, the force required to deform the connection portion 83 can be reduced. In the present embodiment, the opening 84 is a square hole having a long side 84 a extending along the longitudinal direction of the leaf spring 80 and a short side 84 b extending perpendicularly to the longitudinal direction. As a result, when the entire width of each position in the longitudinal direction of the connecting portion 83 is constant, the substantial plate width (that is, the length obtained by removing the width of the opening 84 from the plate width) at the connecting portion 83 is set to the leaf spring 80. Therefore, when the connecting portion 83 is deformed, the amount of deformation at each position in the longitudinal direction of the connecting portion 83 can be made substantially uniform. That is, it is possible to suppress the local deformation of the connection portion 83. Further, the connection portion 83 is bent with a curvature radius smaller than the curvature radius of the curved shape of the first plate portion 81. In other words, the connecting portion 83 is bent with a curvature larger than the curvature of the curved shape of the first plate portion 81 (that is, the reciprocal of the radius of curvature). In other words, the connecting portion 83 has a shape that is smoothly curved from the first plate portion 81 to the second plate portion 82. Thus, the force required to deform the bent connecting portion 83 in a direction closer to a straight line than when the connecting portion 83 is bent by bending the connecting portion 83 with a predetermined radius of curvature. Can be reduced. The radius of curvature of the connecting portion 83 is not particularly limited, but may be larger than the plate thickness of the leaf spring 80. Although the plate | board thickness of a leaf | plate spring is not specifically limited, For example, it is about 0.4 mm. In the present embodiment, the radius of curvature of the connecting portion 83 is about 10 mm.

爪状部87は、板バネ80の二つの端部のうち、自由端側の端部である。爪状部87は、第二板部82に接続されており、図2に示されるように、第二板部82に対して鉛直方向下向きにほぼ直角に折り曲げられている。爪状部87を造営材に形成された取付穴の引っ掛けることにより、照明器具10を造営材から第二板部82の長さ程度引き出した位置において仮留めすることができる。   The claw-shaped portion 87 is an end portion on the free end side of the two end portions of the leaf spring 80. The claw-shaped portion 87 is connected to the second plate portion 82 and is bent substantially perpendicularly downward in the vertical direction with respect to the second plate portion 82 as shown in FIG. By hooking the claw-like portion 87 into the attachment hole formed in the construction material, the lighting device 10 can be temporarily fastened at a position where the second plate portion 82 is pulled out from the construction material.

板バネ80を形成する材料は、弾性部材であれば特に限定されない。板バネ80は、例えば鋼材、アルミニウムなどの金属材料で形成される。また、板バネ80の湾曲形状及び屈曲形状は、例えば金型に板状部材を押し当てることによって形成できる。   The material forming the leaf spring 80 is not particularly limited as long as it is an elastic member. The leaf spring 80 is formed of a metal material such as steel or aluminum, for example. Further, the curved shape and the bent shape of the leaf spring 80 can be formed, for example, by pressing a plate-like member against a mold.

[2.作用及び効果]
本実施の形態に係る照明器具10の作用及び効果について図面を用いて説明する。
[2. Action and Effect]
The operation and effect of the lighting fixture 10 according to the present embodiment will be described with reference to the drawings.

図6は、本実施の形態に係る照明器具10を造営材に取り付ける際における板バネ80の形状を示す斜視図である。図7は、本実施の形態に係る照明器具10を造営材900に取り付けた状態を示す斜視図である。   FIG. 6 is a perspective view showing the shape of the leaf spring 80 when the lighting fixture 10 according to the present embodiment is attached to the construction material. FIG. 7 is a perspective view showing a state in which the lighting fixture 10 according to the present embodiment is attached to the building material 900.

図6に示されるように、本実施の形態に係る照明器具10を造営材900に取り付ける際には、造営材900に形成された取付穴910に板バネ80の自由端を挿入するために、板バネ80を器具本体20側に向けて変形させる。このように板バネ80を変形させた状態を維持して、照明器具10の器具本体20を取付穴910に挿入する。そして、板バネ80の自由端が取付穴910を通過した後、板バネ80の自由端を解放する。続いて、照明器具10の固定枠30の鍔状部29に造営材900が当接するまで照明器具10を取付穴910に押し入れる。このようにして、図7に示されるように、照明器具10を造営材900に取り付けられる。   As shown in FIG. 6, when the lighting apparatus 10 according to the present embodiment is attached to the construction material 900, in order to insert the free end of the leaf spring 80 into the attachment hole 910 formed in the construction material 900, The leaf spring 80 is deformed toward the instrument body 20 side. Thus, the state which deform | transformed the leaf | plate spring 80 is maintained, and the fixture main body 20 of the lighting fixture 10 is inserted in the attachment hole 910. FIG. Then, after the free end of the leaf spring 80 passes through the mounting hole 910, the free end of the leaf spring 80 is released. Subsequently, the lighting fixture 10 is pushed into the mounting hole 910 until the construction material 900 comes into contact with the bowl-shaped portion 29 of the fixed frame 30 of the lighting fixture 10. In this way, as shown in FIG. 7, the lighting fixture 10 is attached to the building material 900.

ここで、図6に示されるように、照明器具10を造営材900に取り付ける際に、板バネ80を変形させる必要がある。板バネ80を変形させるために要する力が大きい場合には、板バネ80の第一板部81などにも大きい力が加わり、第一板部81などが塑性変形し得る。これにより、第一板部81の湾曲形状の曲率半径が増大するため、第一板部81が設計どおりの力で造営材900を押すことができなくなる。本実施の形態に係る板バネ80では、上述のとおり、第一板部81と第二板部82とを接続する接続部83には、接続部83を厚さ方向に貫通する開口部84が形成されている。また、接続部83は、第一板部81の湾曲形状の曲率半径より小さい曲率半径で屈曲されている。このように接続部83は、変形させるために要する力を低減できる構成を有する。このため、板バネ80を図6に示されるような形状に変形させる際に要する力を低減できるため、第一板部81に加えられる力も低減できる。したがって、第一板部81の塑性変形を抑制できる。これにより、第一板部81によって造営材900を押す力が低下することを抑制できる。   Here, as shown in FIG. 6, when attaching the lighting fixture 10 to the construction material 900, it is necessary to deform the leaf spring 80. When the force required to deform the leaf spring 80 is large, a large force is also applied to the first plate portion 81 and the like of the leaf spring 80, and the first plate portion 81 and the like can be plastically deformed. Thereby, since the curvature radius of the curved shape of the first plate portion 81 increases, the first plate portion 81 cannot press the construction material 900 with a force as designed. In the leaf spring 80 according to the present embodiment, as described above, the connection portion 83 that connects the first plate portion 81 and the second plate portion 82 has the opening portion 84 that penetrates the connection portion 83 in the thickness direction. Is formed. Further, the connecting portion 83 is bent with a curvature radius smaller than the curvature radius of the curved shape of the first plate portion 81. Thus, the connection part 83 has the structure which can reduce the force required in order to make it deform | transform. For this reason, since the force required when deforming the leaf spring 80 to the shape as shown in FIG. 6 can be reduced, the force applied to the first plate portion 81 can also be reduced. Therefore, plastic deformation of the first plate portion 81 can be suppressed. Thereby, it can suppress that the force which pushes the construction material 900 by the 1st board part 81 falls.

ここで、図面を用いて比較例に係る板バネと対比しながら、本実施の形態に係る板バネ80の効果を説明する。   Here, the effect of the leaf spring 80 according to the present embodiment will be described with reference to the drawings, in comparison with the leaf spring according to the comparative example.

図8は、比較例に係る板バネ880の外観を示す側面図である。図8には、本実施の形態に係る板バネ80の外観も破線で示されている。   FIG. 8 is a side view showing an appearance of a leaf spring 880 according to a comparative example. In FIG. 8, the appearance of the leaf spring 80 according to the present embodiment is also indicated by a broken line.

図8に示されるように、比較例に係る板バネ880は、本実施の形態に係る板バネ80と同様に、取付板部888と、第一板部881と、第二板部882と、接続部883と、爪状部887とを備える。ただし、図8に示されるように、板バネ880は、接続部883において折り曲げられている点、つまり、接続部883において実質的に曲率半径ゼロで折り曲げられている点において、板バネ80と相違する。また、図示しないが、接続部883は、開口部が形成されていない点においても、板バネ80と相違する。   As shown in FIG. 8, the leaf spring 880 according to the comparative example is the same as the leaf spring 80 according to the present embodiment, the mounting plate portion 888, the first plate portion 881, the second plate portion 882, A connection portion 883 and a claw-like portion 887 are provided. However, as shown in FIG. 8, the leaf spring 880 is different from the leaf spring 80 in that it is bent at the connecting portion 883, that is, it is bent at the connecting portion 883 with substantially zero curvature radius. To do. Although not shown, the connection portion 883 is different from the leaf spring 80 in that an opening is not formed.

ここで、本実施の形態に係る板バネ80、及び、比較例に係る板バネ880を変形させた場合の形状について図面を用いて説明する。   Here, the shape when the leaf spring 80 according to the present embodiment and the leaf spring 880 according to the comparative example are deformed will be described with reference to the drawings.

図9は、本実施の形態に係る板バネ80、及び、比較例に係る板バネ880を変形させた場合の外観を示す側面図である。図9においては、板バネ80及び880の側面図が、それぞれ実線及び破線で重ねて示されている。   FIG. 9 is a side view showing an external appearance when the leaf spring 80 according to the present embodiment and the leaf spring 880 according to the comparative example are deformed. In FIG. 9, side views of the leaf springs 80 and 880 are shown superimposed with solid lines and broken lines, respectively.

図9に示されるように、比較例に係る板バネ880においては、折り曲げられた接続部883を変形させるために要する力が、第一板部881を変形させるために要する力と同等以上に大きいため、第一板部881にも比較的大きな力が加わる。このため、図9に示されるように板バネ880を変形させた場合には、第一板部881には、比較的大きい力が加わる。これに伴い第一板部881は塑性変形し得る。   As shown in FIG. 9, in the leaf spring 880 according to the comparative example, the force required to deform the bent connection portion 883 is equal to or greater than the force required to deform the first plate portion 881. For this reason, a relatively large force is also applied to the first plate portion 881. For this reason, when the leaf spring 880 is deformed as shown in FIG. 9, a relatively large force is applied to the first plate portion 881. Accordingly, the first plate portion 881 can be plastically deformed.

一方、本実施の形態に係る板バネ80においては、接続部83を変形させるために要する力が、第一板部81を変形させるために要する力より小さいため、第一板部81に加わる力は比較的小さい。このため、第一板部81の塑性変形を抑制できる。   On the other hand, in the leaf spring 80 according to the present embodiment, the force applied to the first plate portion 81 is less than the force required to deform the first plate portion 81 because the force required to deform the connection portion 83 is smaller. Is relatively small. For this reason, the plastic deformation of the first plate portion 81 can be suppressed.

なお、本実施の形態では、板バネ80の接続部83に開口部84を形成する構成と、接続部83を第一板部81の湾曲形状の曲率半径より小さい曲率半径で屈曲する構成との両構成を採用しているが、いずれか一方の構成だけを採用してもよい。いずれか一方の構成を採用するだけでも、第一板部81の塑性変形を抑制することができる。   In the present embodiment, a configuration in which the opening 84 is formed in the connection portion 83 of the leaf spring 80 and a configuration in which the connection portion 83 is bent with a curvature radius smaller than the curvature radius of the curved shape of the first plate portion 81. Both configurations are employed, but only one of the configurations may be employed. The plastic deformation of the first plate portion 81 can be suppressed only by adopting one of the configurations.

[3.まとめ]
以上のように、本実施の形態に係る照明器具10は、造営材900に形成された取付穴910に取り付けられる照明器具10である。照明器具10は、光源50と、光源50が取り付けられる器具本体20と、器具本体20を支持する固定枠30と、固定枠30を取付穴910に固定する板バネ80とを備える。板バネ80は、第一板部81と、第二板部82と、第一板部81及び第二板部82を接続し、屈曲形状を有する接続部83とを備え、第一板部81は、湾曲形状を有し、接続部83には、接続部83を厚さ方向に貫通する開口部84が形成されている。
[3. Summary]
As mentioned above, the lighting fixture 10 which concerns on this Embodiment is the lighting fixture 10 attached to the attachment hole 910 formed in the construction material 900. FIG. The lighting fixture 10 includes a light source 50, a fixture main body 20 to which the light source 50 is attached, a fixed frame 30 that supports the fixture main body 20, and a leaf spring 80 that fixes the fixed frame 30 to the mounting hole 910. The leaf spring 80 includes a first plate portion 81, a second plate portion 82, a connection portion 83 that connects the first plate portion 81 and the second plate portion 82 and has a bent shape, and includes the first plate portion 81. Has a curved shape, and the connection portion 83 is formed with an opening 84 that penetrates the connection portion 83 in the thickness direction.

このように、板バネ80の接続部83に開口部84が形成されていることにより、接続部83を変形させるために要する力を低減できる。したがって、照明器具10を造営材900に取り付けるために板バネ80を変形させる際に、第一板部81に加わる力を低減できる。これにより、第一板部81の塑性変形を抑制できるため、第一板部81によって造営材900を押す力が低下することを抑制できる。   As described above, since the opening 84 is formed in the connection portion 83 of the leaf spring 80, the force required to deform the connection portion 83 can be reduced. Therefore, when the leaf spring 80 is deformed in order to attach the lighting fixture 10 to the building material 900, the force applied to the first plate portion 81 can be reduced. Thereby, since the plastic deformation of the 1st board part 81 can be suppressed, it can suppress that the force which pushes the construction material 900 by the 1st board part 81 falls.

また、照明器具10において、開口部84は、板バネ80の長手方向に沿って延びる長辺84aを有してもよい。   In the luminaire 10, the opening 84 may have a long side 84 a extending along the longitudinal direction of the leaf spring 80.

これにより、接続部83の長手方向の各位置における全幅が一定である場合、接続部83における実質的な板幅を板バネ80の長手方向において略一定とすることができるため、接続部83を変形させる際に、接続部83の長手方向の各位置における変形量をほぼ一様にすることができる。つまり、接続部83が局所的に変形することを抑制できる。   Thereby, when the total width at each position in the longitudinal direction of the connecting portion 83 is constant, the substantial plate width at the connecting portion 83 can be made substantially constant in the longitudinal direction of the leaf spring 80. When deforming, the amount of deformation at each position in the longitudinal direction of the connecting portion 83 can be made substantially uniform. That is, it is possible to suppress the local deformation of the connection portion 83.

また、照明器具10において、開口部84は、板バネ80の長手方向に沿って延びる角穴であってもよい。   In the luminaire 10, the opening 84 may be a square hole extending along the longitudinal direction of the leaf spring 80.

このような形状の開口部84を形成することで、接続部83における実質的な板幅を板バネ80の長手方向において略一定とすることができるため、接続部83を変形させる際に、接続部83の長手方向の各位置における変形量をほぼ一様にすることができる。   By forming the opening 84 having such a shape, the substantial plate width of the connection portion 83 can be made substantially constant in the longitudinal direction of the leaf spring 80. Therefore, when the connection portion 83 is deformed, the connection portion 83 is connected. The amount of deformation at each position in the longitudinal direction of the portion 83 can be made substantially uniform.

また、照明器具10において、接続部83は、第一板部81の湾曲形状の曲率半径より小さい曲率半径で曲げられていてもよい。   Further, in the lighting fixture 10, the connection portion 83 may be bent with a curvature radius smaller than the curvature radius of the curved shape of the first plate portion 81.

このように、接続部83が第一板部81の湾曲形状の曲率半径より小さい曲率半径で曲げられていることにより、接続部83が折り曲げられている場合より、接続部83を変形させるために要する力を低減できる。   As described above, since the connection portion 83 is bent with a curvature radius smaller than the curvature radius of the curved shape of the first plate portion 81, the connection portion 83 is deformed more than when the connection portion 83 is bent. The required force can be reduced.

以上、本発明に係る照明器具について、実施の形態に基づいて説明したが、本発明は、上記実施の形態に限定されるものではない。
(Variations, etc.)
As mentioned above, although the lighting fixture which concerns on this invention was demonstrated based on embodiment, this invention is not limited to the said embodiment.

例えば、上記実施の形態において、開口部84は、接続部83全体にわたって形成されたが、接続部83の一部だけに形成されてもよい。また、開口部84の形状は、角穴でなくてもよく、例えば、長円状などでもよい。また、開口部84は、一つでなくもよく、例えば、複数の角穴、複数の丸穴などで構成されてもよい。   For example, in the above embodiment, the opening 84 is formed over the entire connection portion 83, but may be formed only in a part of the connection portion 83. The shape of the opening 84 may not be a square hole, and may be, for example, an oval shape. Moreover, the opening part 84 may not be one, for example, may be comprised by several square holes, several round holes, etc.

また、上記の実施の形態において、光源50は基台上にLEDチップを直接実装したCOB構造を有したが、これに限定されない。例えば、COB構造のLEDモジュールに代えて、SMD(Surface Mount Device)構造のLEDモジュールを用いても構わない。SMD構造のLEDモジュールは、樹脂製のパッケージ(容器)の凹部の中にLEDチップ(発光素子)を実装して当該凹部内に封止部材(蛍光体含有樹脂)を封入したパッケージ型のLED素子(SMD型LED素子)を、1個又は複数個、基板に実装した構成である。   In the above embodiment, the light source 50 has the COB structure in which the LED chip is directly mounted on the base. However, the present invention is not limited to this. For example, an LED module having an SMD (Surface Mount Device) structure may be used in place of the LED module having a COB structure. An LED module having an SMD structure is a package type LED element in which an LED chip (light emitting element) is mounted in a recess of a resin package (container) and a sealing member (phosphor-containing resin) is enclosed in the recess. One or a plurality of (SMD type LED elements) is mounted on a substrate.

また、上記の各実施の形態では、発光素子としてLEDを例示したが、発光素子としては、半導体レーザ等の半導体発光素子、又は、有機EL(Electro Luminescence)素子や無機EL等のその他の固体発光素子を用いてもよい。   In each of the above embodiments, the LED is exemplified as the light emitting element. However, as the light emitting element, a semiconductor light emitting element such as a semiconductor laser, or other solid light emitting elements such as an organic EL (Electro Luminescence) element or an inorganic EL. An element may be used.

また、上記の実施の形態における照明器具10は、天井以外の造営材に取り付けられてもよい。   Moreover, the lighting fixture 10 in said embodiment may be attached to construction materials other than a ceiling.

その他、各実施の形態に対して当業者が思いつく各種変形を施して得られる形態や、本発明の趣旨を逸脱しない範囲で各実施の形態における構成要素及び機能を任意に組み合わせることで実現される形態も本発明に含まれる。   In addition, it is realized by arbitrarily combining the components and functions in each embodiment without departing from the scope of the present invention, and forms obtained by making various modifications conceived by those skilled in the art to each embodiment. Forms are also included in the present invention.
