[Lighting part]
The lighting unit 50 has a cover member 51 , blocking members 52 and 53 , water stop packings 54 and 55 , a light emitting unit 60 , a power supply unit 70 , and holding metal fittings 80 and 81 . The light emitting section 60 and the power supply section 70 are housed inside a cover member 51 formed in a cylindrical shape. A pair of holding metal fittings 80, 81, a pair of waterproof packings 54, 55, and a pair of closing members 52, 53 are arranged in this order at both ends in the length direction (Y-axis direction) of the cover member 51. Moisture resistance is realized for the light emitting unit 60 and the power supply unit 70 housed in the cover member 51 .

(カバー部材)
カバー部材51は、例えば、アクリルやポリカーボネート等の透光性の材料から作られている。カバー部材51は、フロスト処理が施されて発光部60から出射される光を拡散する機能を有するようになっている。なお、カバー部材51に適宜拡散材や着色剤を混入させてもよい。
(Cover member)
The cover member 51 is made of, for example, translucent material such as acrylic or polycarbonate. The cover member 51 is frosted and has a function of diffusing the light emitted from the light emitting section 60 . Note that the cover member 51 may be appropriately mixed with a diffusion material or a coloring agent.

カバー部材51は、天井面100側に配置される電源収容部51aと、照射面側に配置され、筐体5から厚み方向に突出する拡散部51dと、電源収容部51aと拡散部51dとの間に配置されるくびれ部51bとを有する。また、筐体5から突出するカバー部材51の幅方向の端面51cと天井面100とは、ほぼ直角であり、鋭角である第1角度θ1とは異なる角度をなす。このように端面51cと天井面100との角度を第1角度θ1と異ならせることにより、例えば照射面側だけでなく端面51cを介して照明部50の幅方向にも光が出射されやすくなるため、例えば、照明装置1の演色効果を高めることができる。また、カバー部材51がこのような端面51cを有することにより、例えば筐体5に対する照明部50の取り外しが容易になる。なお、カバー部材51、特に拡散部51dの形状は、例えば所望の配光が得られるよう空間S3の形状を適宜変更してもよい。また、カバー部材51の部位に応じて透光性を変更させてもよい。 The cover member 51 includes a power supply housing portion 51a arranged on the ceiling surface 100 side, a diffusion portion 51d arranged on the irradiation surface side and protruding from the housing 5 in the thickness direction, and the power supply housing portion 51a and the diffusion portion 51d. and a constricted portion 51b disposed therebetween. Further, the widthwise end surface 51c of the cover member 51 protruding from the housing 5 and the ceiling surface 100 are substantially perpendicular and form an angle different from the acute first angle θ1. By making the angle between the end surface 51c and the ceiling surface 100 different from the first angle θ1, for example, light can be easily emitted not only to the irradiation surface side but also to the width direction of the illumination unit 50 via the end surface 51c. For example, the color rendering effect of the illumination device 1 can be enhanced. In addition, since the cover member 51 has such an end surface 51c, the illumination section 50 can be easily removed from the housing 5, for example. Note that the shape of the cover member 51, particularly the diffusion portion 51d, may be changed as appropriate to the shape of the space S3 so as to obtain a desired light distribution, for example. Further, the translucency may be changed depending on the part of the cover member 51 .

(発光部)
発光部60は、第1基板としての基板61と、複数の発光素子62と、支持部材63とを有する。基板61は、長尺の略長方形状に形成されている。基板61は、絶縁材であるガラスエポキシ基板やガラスコンポジット基板の平板からなり、表面側には銅箔で形成された配線パターンが形成されている。基板61の材料は、絶縁材とする場合には、セラミックス材料や他の合成樹脂材料を適用できる。また、基板61を金属製とする場合は、アルミニウム等の熱伝導性が良好で放熱性に優れたべース板の一面に絶縁層が積層された金属製のべース基板を適用できる。なお、基板61は、長さ方向(Y軸方向)に複数並べて配置させてもよい。

The light emitting section 60 has a substrate 61 as a first substrate, a plurality of light emitting elements 62 and a support member 63 . The substrate 61 is formed in a long, substantially rectangular shape. The substrate 61 is made of a flat plate made of a glass epoxy substrate or a glass composite substrate, which is an insulating material, and a wiring pattern made of copper foil is formed on the surface side. If the substrate 61 is made of an insulating material, a ceramic material or other synthetic resin material can be applied. When the substrate 61 is made of metal, a metal base substrate having an insulating layer laminated on one surface of a base plate such as aluminum having good thermal conductivity and excellent heat dissipation can be applied. A plurality of substrates 61 may be arranged side by side in the length direction (Y-axis direction).

また、基板61の表面上には、全面に亘って白色のレジスト層を形成するのが好ましい。このレジスト層は、反射層として作用し、発光素子62から出射される光のうち、基板61の表面に向かう光を前面側に反射させることができ、発光素子62から出射される光を有効に利用することができる。 Moreover, it is preferable to form a white resist layer over the entire surface of the substrate 61 . This resist layer functions as a reflective layer, and can reflect the light directed toward the surface of the substrate 61 out of the light emitted from the light emitting element 62 toward the front side. can be used.

複数の発光素子62は、基板61の長さ方向に沿うように所定の間隔で配置されている。なお、発光素子62の配列は一列であってもよく、二列以上であってもよい。また、発光素子62は、例えば、基板61の長さ方向に沿って、配列方向と交差する幅方向へ位置が交互にずらされた、いわゆる千鳥配列にされてもよい。 The plurality of light emitting elements 62 are arranged at predetermined intervals along the length direction of the substrate 61 . Note that the light emitting elements 62 may be arranged in one row or in two or more rows. Further, the light emitting elements 62 may be arranged in a so-called zigzag arrangement, in which the positions of the light emitting elements 62 are alternately shifted in the width direction that intersects the arrangement direction along the length direction of the substrate 61, for example.

また、複数の発光素子62は、Z軸方向の位置がカバー部材51の端面51cのうち、天井面100寄りとなるように配置されているが、これに限らず、例えば端面51cの照射面寄りに配置されてもよく、また、くびれ部51bの照射面寄りに配置されてもよい。また、複数の発光素子62の配置に応じて、筐体5の厚み方向の寸法を適宜変更させてもよい。 Further, the plurality of light emitting elements 62 are arranged so that the positions in the Z-axis direction are closer to the ceiling surface 100 of the end surface 51c of the cover member 51. , or may be arranged closer to the irradiation surface of the constricted portion 51b. In addition, the dimension of the housing 5 in the thickness direction may be appropriately changed according to the arrangement of the plurality of light emitting elements 62 .

発光素子62は、LEDであり、表面実装型のLEDパッケージである。概略的にはセラミックスや耐熱性の合成樹脂で形成された本体に配設されたLEDチップと、このLEDチップを封止するエポキシ系樹脂やシリコーン樹脂等のモールド用の透光性樹脂とを含む。 The light emitting element 62 is an LED and is a surface-mounted LED package. Schematically, it includes an LED chip arranged in a main body made of ceramics or heat-resistant synthetic resin, and translucent resin for molding such as epoxy resin or silicone resin that seals the LED chip. .

LEDチップは、例えば、青色光を発する青色のLEDチップである。透光性樹脂には、蛍光体が混入されており、白色光を出射できるようにするために、青色の光とは補色の関係にある黄色系の光を放射する黄色蛍光体が使用されている。なお、LEDチップは、例えば赤色光や緑色光、あるいは白色光を発するものであってもよい。また、透光性樹脂は、乳白色を有し、光を拡散させる拡散部材であってもよい。 The LED chip is, for example, a blue LED chip that emits blue light. The translucent resin is mixed with a phosphor, and in order to emit white light, a yellow phosphor that emits yellow light, which is complementary to blue light, is used. there is The LED chip may emit red light, green light, or white light, for example. Also, the translucent resin may be a diffusion member that has a milky white color and diffuses light.

LEDは、砲弾型のLEDを実装するようにしてもよく、実装方式や形式は、特に限定されるものではない。 A cannonball-shaped LED may be mounted as the LED, and the mounting method and form are not particularly limited.

支持部材63は、例えば、金属製のシャーシであり、保持部63aと、接続部63bと、支持部63cと、電源取付部63dとを含む。保持部63aは、複数の発光素子62が実装された基板61を保持する。基板61は、図示しない固定手段によって保持部63aに取り付けられている。複数の発光素子62で発生した熱は、基板61を介して支持部材63に伝わり、放熱される。 The support member 63 is, for example, a chassis made of metal, and includes a holding portion 63a, a connection portion 63b, a support portion 63c, and a power supply mounting portion 63d. The holding portion 63a holds the substrate 61 on which the plurality of light emitting elements 62 are mounted. The substrate 61 is attached to the holding portion 63a by fixing means (not shown). Heat generated by the plurality of light emitting elements 62 is transferred to the support member 63 via the substrate 61 and radiated.

支持部63cは、Y軸方向から見てX軸方向およびZ軸方向に対して斜めに形成されている。支持部材63は、電源収容部51aおよびくびれ部51bで形成されるカバー部材51の内面側の凸部51eに支持部63cが当接することで基板61に実装された複数の発光素子62が予め定められた位置に配置される。 The support portion 63c is obliquely formed with respect to the X-axis direction and the Z-axis direction when viewed from the Y-axis direction. The support member 63 has a plurality of light emitting elements 62 mounted on the substrate 61 predetermined by the support portion 63c coming into contact with the convex portion 51e on the inner surface side of the cover member 51 formed by the power supply housing portion 51a and the constricted portion 51b. placed in the specified position.

接続部63bは、保持部63aの幅方向(X軸方向)の両端からZ軸方向に沿うように延び、保持部63aと支持部63cとを接続する。接続部63bは、後述する点灯部76が保持部63aと離間して配置される程度の寸法を有する。このため、汎用性を向上させることができ、例えば小型化した場合であっても、発光部60の放熱性の低下が抑制される。 The connection portions 63b extend along the Z-axis direction from both ends in the width direction (X-axis direction) of the holding portion 63a, and connect the holding portions 63a and the support portions 63c. The connecting portion 63b has a dimension such that a lighting portion 76, which will be described later, is spaced apart from the holding portion 63a. For this reason, versatility can be improved, and, for example, even when the size is reduced, deterioration in heat dissipation of the light emitting unit 60 is suppressed.

電源取付部63dは、支持部材63の幅方向(X軸方向)の両端に配置される。電源取付部63dには、電源部70が取り付けられる。 The power supply mounting portions 63d are arranged at both ends of the support member 63 in the width direction (X-axis direction). A power supply unit 70 is attached to the power supply attachment portion 63d.

(電源部)
電源部70は、点灯部76と、点灯部76を保持する保持部材77とを有する。点灯部76は、第2基板としての基板75および基板75に実装された複数の点灯部品74を収容する箱形状の部材である。電源部70は、交流電源から供給された交流電力を直流電力に変換して出力する。交流電源は、例えば商用電源である。
(Power supply part)
The power supply section 70 has a lighting section 76 and a holding member 77 that holds the lighting section 76 . The lighting unit 76 is a box-shaped member that accommodates a substrate 75 as a second substrate and a plurality of lighting components 74 mounted on the substrate 75 . The power supply unit 70 converts AC power supplied from an AC power supply into DC power and outputs the DC power. The AC power supply is, for example, a commercial power supply.

点灯部76は、基板75上の配線パターンおよび図示しない配線により複数の発光素子62に接続されている。点灯部76は、複数の発光素子62に対して直流出力を供給するとともに、複数の発光素子62の点灯を制御する。 The lighting section 76 is connected to the plurality of light emitting elements 62 by wiring patterns on the substrate 75 and wiring (not shown). The lighting unit 76 supplies DC output to the plurality of light emitting elements 62 and controls lighting of the plurality of light emitting elements 62 .

点灯部76は、厚み方向(Z軸方向)の端部に位置する底面71と、幅方向(X軸方向)の両端に位置する側面73と、底面71と側面73との間に位置する傾斜部72とを有する。傾斜部72は、支持部材63の支持部63cを介してくびれ部51bの内面で支持される。このように点灯部76がくびれ部51bの内面で支持される形状を有することにより、カバー部材51の内部空間を有効に活用することができ、例えば、照明装置1を小型化することができる。 The lighting portion 76 has a bottom surface 71 located at an end in the thickness direction (Z-axis direction), side surfaces 73 located at both ends in the width direction (X-axis direction), and slopes located between the bottom surface 71 and the side surfaces 73 . and a portion 72 . The inclined portion 72 is supported by the inner surface of the constricted portion 51 b via the support portion 63 c of the support member 63 . Since the lighting portion 76 has a shape supported by the inner surface of the constricted portion 51b in this way, the internal space of the cover member 51 can be effectively utilized, and for example, the illumination device 1 can be miniaturized.

基板75は、複数の点灯部品74よりも天井面100側に配置される。このため、発光部60で発生する熱と電源部70で発生する熱とを離れた位置で放熱させることができ、放熱性を向上することができる。このとき、発光部60と電源部70との間に空間S2を有することで、放熱性をさらに向上することができる。 The board 75 is arranged closer to the ceiling surface 100 than the lighting components 74 are. Therefore, the heat generated by the light emitting unit 60 and the heat generated by the power supply unit 70 can be dissipated at separate positions, and heat dissipation can be improved. At this time, providing a space S2 between the light emitting unit 60 and the power supply unit 70 can further improve heat dissipation.

保持部材77は、例えば、金属製の放熱部材であり、点灯部76から伝わった熱を放熱する。また、保持部材77は、幅方向(X軸方向)の両端に長さ方向に沿って延びる取付部78を有する。取付部78は、支持部材63の電源取付部63dに取り付けられることにより、発光部60および電源部70が一体化される。 The holding member 77 is, for example, a heat radiating member made of metal, and radiates heat transmitted from the lighting portion 76 . In addition, the holding member 77 has attachment portions 78 extending along the length direction at both ends in the width direction (X-axis direction). The attachment portion 78 is attached to the power source attachment portion 63d of the support member 63, so that the light emitting portion 60 and the power source portion 70 are integrated.

(その他の構成)
図2に示すように、照明部50は、補強部材90をさらに有してもよい。補強部材90は、例えば金属製または樹脂製の棒状または線状の部材であり、カバー部材51の幅方向の両端を挟み込むとともに端部をくびれ部51bに引掛けるように配置される。例えば取付部10を天井面100に取り付けると、カバー部材51に収容された発光部60や電源部70の自重によりカバー部材51が変形し、所望の照射特性が得られない場合がある。そこで、補強部材90を配置することでカバー部材51の強度を高め、カバー部材51の変形を低減することができる。補強部材90は、例えば複数の基板61を長さ方向に配列させる態様において特に有用である。なお、使用する補強部材90は、1または複数であってもよく、使用しなくてもよい。
(Other configurations)
As shown in FIG. 2 , the lighting section 50 may further have a reinforcing member 90 . The reinforcing member 90 is, for example, a rod-shaped or linear member made of metal or resin, and is arranged so as to sandwich both ends of the cover member 51 in the width direction and to hook the ends to the constricted portion 51b. For example, when the mounting portion 10 is attached to the ceiling surface 100, the cover member 51 may be deformed by the weight of the light emitting portion 60 and the power supply portion 70 accommodated in the cover member 51, and desired irradiation characteristics may not be obtained. Therefore, by arranging the reinforcing member 90, the strength of the cover member 51 can be increased and the deformation of the cover member 51 can be reduced. The reinforcing member 90 is particularly useful, for example, in a mode in which a plurality of substrates 61 are arranged in the longitudinal direction. One or a plurality of reinforcing members 90 may be used, or none may be used.

[発光部および電源部の一体化]
図4は、照明部の内部構成を示す分解斜視図である。支持部材63は、電源取付部63dの内面に複数の凹部66を有する。一方、保持部材77は、複数の凹部66に対応する取付部78の外面に複数の凸部79を有する。支持部材63および保持部材77を互いに近づけ、複数の凹部66に複数の凸部79を係合させることにより、発光部60および電源部70が一体化される。なお、支持部材63および保持部材77の一体化は図示した形態に限らず、例えば支持部材63が凸部を、保持部材77が凹部を、それぞれ有してもよい。
[Integration of light emitting part and power supply part]
FIG. 4 is an exploded perspective view showing the internal configuration of the lighting section. The support member 63 has a plurality of recesses 66 on the inner surface of the power supply mounting portion 63d. On the other hand, the holding member 77 has a plurality of protrusions 79 on the outer surface of the mounting portion 78 corresponding to the plurality of recesses 66 . By bringing the supporting member 63 and the holding member 77 close to each other and engaging the plurality of convex portions 79 with the plurality of concave portions 66, the light emitting portion 60 and the power source portion 70 are integrated. The integration of the support member 63 and the holding member 77 is not limited to the illustrated form. For example, the support member 63 may have a convex portion and the holding member 77 may have a concave portion.

また、図4に示す例では、保持部材77は、支持部材63よりも長さ方向の寸法が小さい。このため、保持部材77を配設させる自由度が高まる。すなわち、図示した例では、保持部材77は支持部材63のY軸負方向側に配設させたが、これに限らず、Y軸正方向側に配設させてもよい。また、保持部材77を含む電源部70を、Y軸方向の全体にわたって支持部材63と一体化するように配設させてもよい。 Further, in the example shown in FIG. 4 , the holding member 77 has a smaller dimension in the length direction than the supporting member 63 . Therefore, the degree of freedom in arranging the holding member 77 is increased. That is, in the illustrated example, the holding member 77 is arranged on the Y-axis negative direction side of the supporting member 63, but is not limited to this, and may be arranged on the Y-axis positive direction side. Also, the power supply unit 70 including the holding member 77 may be arranged so as to be integrated with the support member 63 over the entire Y-axis direction.

[保持金具の接続]
次に、保持金具80、81(図2参照)の接続について、図4を用いてさらに説明する。図4に示すように、支持部材63は、接続部63bの長さ方向(Y軸方向)の両端部を貫通するガイド穴63eを有する。保持金具80および図示しない保持金具81は、ガイド穴63eに対応する位置に突出部82を有する。ガイド穴63eおよび突出部82は、一対の係止機構の一例である。ガイド穴63eおよび突出部82を互いに係止させることにより、照明部50および保持金具80、81が接続される。このとき、図示するように突出部82のY軸方向の寸法に対し、ガイド穴63eのY軸方向の寸法を大きくすると、熱による支持部材63の長さ方向の変形を緩衝することができる。
[Connecting the holding bracket]
Next, the connection of the holding metal fittings 80 and 81 (see FIG. 2) will be further described with reference to FIG. As shown in FIG. 4, the support member 63 has guide holes 63e passing through both ends in the length direction (Y-axis direction) of the connecting portion 63b. The holding metal fitting 80 and the holding metal fitting 81 (not shown) have protrusions 82 at positions corresponding to the guide holes 63e. The guide hole 63e and the projecting portion 82 are an example of a pair of locking mechanisms. By engaging the guide hole 63e and the projecting portion 82 with each other, the illumination portion 50 and the holding metal fittings 80, 81 are connected. At this time, if the dimension of the guide hole 63e in the Y-axis direction is made larger than the dimension of the protrusion 82 in the Y-axis direction as shown in the figure, the deformation of the support member 63 in the length direction due to heat can be buffered.

[閉塞部材の固定]
次に、閉塞部材52、53の固定について、図5を用いて説明する。図5は、第1の実施形態に係る照明装置を示す側面図である。なお、理解の容易のため、図5では側板41の図示を省略している。
[Fixation of closing member]
Next, fixation of the closing members 52 and 53 will be described with reference to FIG. FIG. 5 is a side view showing the lighting device according to the first embodiment. For easy understanding, illustration of the side plate 41 is omitted in FIG.

図5に示すように、閉塞部材53は、第1部位53aと、くびれ部位としての第2部位53bと、第3部位53cとを有する。第1部位53a、第2部位53bおよび第3部位53cはそれぞれ、カバー部材51の電源収容部51a、くびれ部51b、拡散部51dに対応するように形成されている。閉塞部材52(図2参照)および閉塞部材53は、止水パッキン54、55(図2参照)を挟むようにカバー部材51の長さ方向(Y軸方向)の両端を塞ぎ、複数のネジ部材57で固定される。ネジ部材57は、第1部位53aの中央を固定するネジ部材57aと、第2部位53bに幅方向に並ぶ2つのネジ部材57b、57cとを含む。このように第1部位53aおよび第3部位53cと比較して幅方向の寸法が小さい第2部位53bを2つのネジ部材57b、57cで固定し、さらに天井面100側の第1部位53aをネジ部材57aで固定することにより、例えば閉塞部材53の撓みによる防湿性の低下を抑制することができる。 As shown in FIG. 5, the closing member 53 has a first portion 53a, a second portion 53b as a constricted portion, and a third portion 53c. The first portion 53a, the second portion 53b, and the third portion 53c are formed to correspond to the power source accommodating portion 51a, the constricted portion 51b, and the diffusion portion 51d of the cover member 51, respectively. A closing member 52 (see FIG. 2) and a closing member 53 close both ends in the longitudinal direction (Y-axis direction) of the cover member 51 so as to sandwich the waterproof packings 54 and 55 (see FIG. 2). 57. The screw member 57 includes a screw member 57a that fixes the center of the first portion 53a, and two screw members 57b and 57c that are arranged in the width direction of the second portion 53b. Thus, the second portion 53b, which is smaller in width than the first portion 53a and the third portion 53c, is fixed by two screw members 57b and 57c, and the first portion 53a on the ceiling surface 100 side is screwed. By fixing with the member 57a, it is possible to suppress deterioration in moisture resistance due to bending of the closing member 53, for example.

なお、閉塞部材53には、配線孔56が形成されている。配線孔56は、電源部70(点灯部76)に対して電力を供給するための配線を挿通し、カバー部材51の内部に引き込むための開口である。配線孔56は、ネジ部材57の外側に配置されることで、ネジ部材57の装着時における断線などの不具合を防止する。なお、図5では、3つの配線孔56を有するとして図示したが、これに限らず、1、2、または4以上の配線孔56を有してもよい。また、配線孔56は、閉塞部材53のみに配置されてもよく、閉塞部材52、53の両方に配置されてもよい。 A wiring hole 56 is formed in the closing member 53 . The wiring hole 56 is an opening through which a wiring for supplying electric power to the power source section 70 (lighting section 76 ) is inserted and pulled into the cover member 51 . By arranging the wiring hole 56 outside the screw member 57 , problems such as wire breakage when the screw member 57 is attached can be prevented. Although FIG. 5 illustrates that there are three wiring holes 56, the present invention is not limited to this, and one, two, or four or more wiring holes 56 may be provided. Also, the wiring hole 56 may be arranged only in the closing member 53 or may be arranged in both the closing members 52 and 53 .

なお、固定化部材58は、閉塞部材53に側板41を取り付けるために使用される。固定化部材58は、閉塞部材53のZ軸正方向側から側板41に形成された貫通孔41a(図2参照)に挿通され、閉塞部材53と側板41とが固定される。固定化部材58を挿通させるための開口は、封止ブッシュ59で封止される。 In addition, the fixing member 58 is used to attach the side plate 41 to the closing member 53 . The fixing member 58 is inserted through the through hole 41a (see FIG. 2) formed in the side plate 41 from the Z-axis positive direction side of the closing member 53, and the closing member 53 and the side plate 41 are fixed. The opening for inserting the fixing member 58 is sealed with a sealing bush 59 .

[第2、第3の実施形態]
図6は、第2および第3の実施形態に係る照明装置が有する筐体の構成の一例を模式的に示す斜視図である。図6(a)は、第2の実施形態に係る筐体5Aを、図6(b)は、第3の実施形態に係る筐体5Bを、それぞれ図示している。
[Second and Third Embodiments]
FIG. 6 is a perspective view schematically showing an example of the configuration of a housing included in lighting devices according to the second and third embodiments. FIG. 6(a) shows a housing 5A according to the second embodiment, and FIG. 6(b) shows a housing 5B according to the third embodiment.

図6(a)に示すように、反射部30が照射面側に向かって傾斜するように配置された筐体5Aを適用してもよい。筐体5Aには、収容部20の長さ方向の両端201から所定の長さL1を有する欠損部21Aを設けることができる。欠損部21Aは、閉塞部材52、53と接触または近接する位置に配置される。欠損部21Aには、反射部30を有しないため、筐体5と閉塞部材52、53との緩衝による変形や防湿性の低下等の不具合を防止することができる。 As shown in FIG. 6A, a housing 5A in which the reflecting section 30 is arranged to be inclined toward the irradiation surface side may be applied. The housing 5A can be provided with cutout portions 21A having a predetermined length L1 from both ends 201 of the accommodating portion 20 in the longitudinal direction. The cutout portion 21A is arranged at a position in contact with or close to the closing members 52 and 53 . Since the cutout portion 21A does not have the reflecting portion 30, it is possible to prevent problems such as deformation due to cushioning between the housing 5 and the closing members 52 and 53, deterioration of moisture resistance, and the like.

また、図6(b)に示すように、反射部30を有しない筐体5Bを適用してもよい。かかる場合、閉塞部材52、53と接触または近接する収容部20の長さ方向の両端201に切欠部21Bを設け、筐体5と閉塞部材52、53との緩衝による変形や防湿性の低下等の不具合を防止することができる。 Further, as shown in FIG. 6B, a housing 5B without the reflecting section 30 may be applied. In such a case, notch portions 21B are provided at both ends 201 in the longitudinal direction of the accommodating portion 20 that contact or are close to the closing members 52 and 53, and deformation due to cushioning between the housing 5 and the closing members 52 and 53, deterioration of moisture resistance, etc. problems can be prevented.

なお、図6(a)、図6(b)において、取付部10と収容部20とのなす角度θ3は、例えば90°とすることができるが、これに限らず、例えば鋭角または鈍角であってもよい。 In FIGS. 6(a) and 6(b), the angle θ3 formed by the mounting portion 10 and the housing portion 20 can be, for example, 90°, but is not limited to this, and can be, for example, an acute angle or an obtuse angle. may

上述したように、実施形態に係る照明装置1は、照明部50と筐体5とを具備する。照明部50は、複数の発光素子62を有する。筐体5は、板状であり、第1部分(取付部10)と、一対の第2部分(収容部20)と、一対の第3部分(反射部30)とを有する。第1部分は、取付面(天井面100)に対向して配置される。一対の第2部分は、第1部分の幅方向の両端から幅方向に交差する厚み方向に屈曲し、照明部50を収容する。一対の第3部分は、一対の第2部分の各端部から取付面側に屈曲する。筐体5は、取付面側の幅方向の寸法Aが、厚み方向の寸法Bよりも大きく、取付面と第3部分とのなす第1角度θ1が、第2部分と第3部分とのなす第2角度θ2よりも大きい。これにより、照明装置1の特に幅方向の形状を小型化することができる。また、かかる形状を有する筐体5は、例えば小型化や長尺化した場合であっても成形が容易である。このため、汎用性を向上させることができる。 As described above, the lighting device 1 according to the embodiment includes the lighting section 50 and the housing 5 . The lighting section 50 has a plurality of light emitting elements 62 . The housing 5 is plate-shaped and has a first portion (mounting portion 10), a pair of second portions (accommodating portions 20), and a pair of third portions (reflecting portions 30). The first portion is arranged to face the mounting surface (ceiling surface 100). The pair of second portions are bent in a thickness direction that intersects the width direction from both ends of the first portion in the width direction, and accommodate the lighting section 50 . The pair of third portions bends toward the mounting surface from each end of the pair of second portions. In the housing 5, the dimension A in the width direction on the mounting surface side is larger than the dimension B in the thickness direction, and the first angle θ1 formed between the mounting surface and the third portion is greater than the first angle θ1 formed between the second portion and the third portion. greater than the second angle θ2. This makes it possible to reduce the size of the illumination device 1 particularly in the width direction. In addition, the housing 5 having such a shape can be easily molded even if it is made smaller or elongated, for example. Therefore, versatility can be improved.

また、実施形態に係る照明部50は、筐体5から厚み方向に突出するカバー部材51を有し、筐体5から突出するカバー部材51の幅方向の端面51cと取付面とは、第1角度θ1とは異なる角度をなす。これにより、例えば、照明装置1の演色効果を高めることができる。また、筐体5に対する照明部50の取り外しが容易になる。このため、汎用性を向上させることができる。 In addition, the illumination unit 50 according to the embodiment has a cover member 51 that protrudes from the housing 5 in the thickness direction. It forms an angle different from the angle θ1. Thereby, for example, the color rendering effect of the illumination device 1 can be enhanced. Moreover, the removal of the illumination unit 50 from the housing 5 is facilitated. Therefore, versatility can be improved.

また、実施形態に係る照明装置1は、複数の発光素子62と、基板61と、支持部材63と、点灯部76とを具備する。基板61は、複数の発光素子62を実装する。支持部材63は、基板61を一面側に配設させる保持部63aを有する。点灯部76は、保持部63aの背面側から離間して配設され、複数の発光素子62を点灯させる。これにより、発光部60の放熱性の低下が抑制され、汎用性を向上させることができる。 Also, the lighting device 1 according to the embodiment includes a plurality of light emitting elements 62 , a substrate 61 , a support member 63 and a lighting section 76 . A substrate 61 mounts a plurality of light emitting elements 62 . The support member 63 has a holding portion 63a on which the substrate 61 is arranged on one side. The lighting section 76 is arranged apart from the back side of the holding section 63a, and lights up the plurality of light emitting elements 62. As shown in FIG. As a result, deterioration of the heat dissipation of the light emitting unit 60 is suppressed, and versatility can be improved.

また、実施形態に係る照明装置1は、点灯部76を保持し、保持部63aよりも長さ方向の寸法が小さい保持部材77を具備する。これにより、保持部材77を配設させる自由度が高まる。 The lighting device 1 according to the embodiment also includes a holding member 77 that holds the lighting portion 76 and has a smaller lengthwise dimension than the holding portion 63a. This increases the degree of freedom in disposing the holding member 77 .

また、実施形態に係る点灯部76は傾斜部72を有し、支持部材63と厚み方向に重なり合って配設されている。支持部材63は、傾斜部72に沿って長さ方向に延びる支持部63cを有する。これにより、放熱性を向上することができ、汎用性を向上させることができる。 Further, the lighting portion 76 according to the embodiment has an inclined portion 72 and is arranged so as to overlap with the support member 63 in the thickness direction. The support member 63 has a support portion 63c that extends longitudinally along the inclined portion 72 . Thereby, heat dissipation can be improved and versatility can be improved.
