特開２０１７−８４５７７号公報JP-A-2017-84577

特許文献１の照明装置は、光源及びカバーがネジ等の固定部材で取付板に固定されているが、例えばエレベータのかご内等に設置した場合、エレベータの振動を長期に亘り受け続けると、固定部材による固定状態が緩み、光源又はカバーが位置ずれを起こすおそれがある。その結果、この照明装置は、配光が落ちて既定配光を確保できなくなるおそれがある。 In the lighting device of Patent Document 1, the light source and the cover are fixed to the mounting plate by fixing members such as screws. However, when the lighting device is installed in an elevator car or the like, it is fixed when the elevator is continuously vibrated for a long period of time. The fixed state by the member may be loosened, and the light source or cover may be misaligned. As a result, the light distribution of this illuminating device may drop and the default light distribution may not be ensured.

本発明は、上記のような課題を解決するためになされたもので、光源部とカバー部との相対的な位置ずれを抑制し、安定した既定配光を長期に亘って確保できる照明装置を提供することを目的とする。 The present invention has been made to solve the above problems, and provides a lighting device capable of suppressing a relative positional deviation between a light source unit and a cover unit and ensuring a stable default light distribution for a long period of time. The purpose is to provide.

本発明に係る照明装置は、基板及び前記基板に実装された複数の発光素子を有する光源部と、前記光源部が取り付けられる載置部を有する取付部材と、前記取付部材に取り付けられ、前記光源部を覆うカバー部と、を備え、前記基板には、貫通孔が形成され、前記載置部には、挿入孔が形成されており、前記カバー部には、前記貫通孔を通過して前記基板を前記載置部に押し付けた状態で、前記挿入孔に挿入される突出部が設けられている。 The lighting device according to the present invention includes a substrate, a light source portion having a plurality of light emitting elements mounted on the substrate, a mounting member having a mounting portion on which the light source portion is mounted, and a light source mounted on the mounting member. A cover portion for covering the portion is provided, a through hole is formed in the substrate, an insertion hole is formed in the above-described mounting portion, and the cover portion passes through the through hole and is said to be described. A protruding portion to be inserted into the insertion hole is provided in a state where the substrate is pressed against the above-described mounting portion.

本発明の照明装置によれば、光源部及びカバー部が、挿入孔に挿入した突出部によって載置部に強固に固定されているので、光源部とカバー部との相対的な位置ずれを抑制することができ、安定した既定配光を長期に亘って確保できる。 According to the lighting device of the present invention, since the light source portion and the cover portion are firmly fixed to the mounting portion by the protruding portion inserted into the insertion hole, the relative positional deviation between the light source portion and the cover portion is suppressed. It is possible to secure a stable default light distribution for a long period of time.

図１及び図２に示した本実施の形態に係る照明装置１００は、例えばエレベータのかご内、ビル又は住宅等の居室内用の照明として用いられるものである。照明装置１００は図１〜図３に示すように、本体部１と、本体部１を覆うカバー部７と、を有している。照明装置１００は、一例として平面視を略正方形とした直方体形状である。但し、照明装置１００は、図示した形状に限定されず、例えば平面視を長方形又は多角形としてもよいし、全体として円柱体形状等の他の形状でもよい。 The lighting device 100 according to the present embodiment shown in FIGS. 1 and 2 is used as lighting for a living room such as an elevator car, a building, or a house, for example. As shown in FIGS. 1 to 3, the lighting device 100 has a main body portion 1 and a cover portion 7 that covers the main body portion 1. As an example, the lighting device 100 has a rectangular parallelepiped shape with a substantially square view in a plan view. However, the lighting device 100 is not limited to the shape shown in the drawing, and may have a rectangular shape or a polygonal shape in a plan view, or may have another shape such as a cylindrical shape as a whole.

本体部１は、図３及び図４に示すように、光源部２と、取付部材３と、ベース部４と、電源部５と、絶縁シート６と、を有している。 As shown in FIGS. 3 and 4, the main body 1 includes a light source 2, a mounting member 3, a base 4, a power supply 5, and an insulating sheet 6.

光源部２は、図３及び図４に示すように、絶縁シート６を介して取付部材３に取り付けられる。図示例の場合は、２つの光源部２を並べて配置した構成としているが、１つの光源部２で構成してもよいし、３つ以上の光源部２を並べて配置した構成でもよい。光源部２は、基板２０と、基板２０に実装された複数の発光素子２１と、電源部５に接続された電源ケーブル５０を接続するためのコネクタ２２と、を有している。基板２０は、長方形状とされ、長辺側の縁部にネジ等の締結部材及びカバー部７の構成部材等を避けるための貫通孔２０ａとして切欠き孔が複数形成されている。なお、貫通孔２０ａは、切欠き孔に限定されず、周囲が囲まれた孔でもよい。 As shown in FIGS. 3 and 4, the light source unit 2 is attached to the attachment member 3 via the insulating sheet 6. In the case of the illustrated example, the two light source units 2 are arranged side by side, but one light source unit 2 may be used, or three or more light source units 2 may be arranged side by side. The light source unit 2 has a substrate 20, a plurality of light emitting elements 21 mounted on the substrate 20, and a connector 22 for connecting a power cable 50 connected to the power supply unit 5. The substrate 20 has a rectangular shape, and a plurality of notch holes are formed on the edge portion on the long side side as through holes 20a for avoiding fastening members such as screws and constituent members of the cover portion 7. The through hole 20a is not limited to the notch hole, and may be a hole surrounded by the periphery.

発光素子２１は、例えばＬＥＤであり、電源部５からの電力供給によって発光する。複数の発光素子２１は、基板２０上に所望の照明特性等が得られるようなパターンで配列されている。図示例の場合、発光素子２１は、各基板２０に２４個ずつ縦横に整列させて設けられている。 The light emitting element 21 is, for example, an LED, and emits light by supplying electric power from the power supply unit 5. The plurality of light emitting elements 21 are arranged on the substrate 20 in a pattern so as to obtain desired lighting characteristics and the like. In the case of the illustrated example, 24 light emitting elements 21 are provided vertically and horizontally on each substrate 20.

コネクタ２２は、電源部５からの電力を発光素子２１に供給する電源ケーブル５０を接続するために設けられている。コネクタ２２は、電源ケーブル５０を接続するための形状及び大きさを有するため、発光素子２１よりも照射側に向かって突き出している。 The connector 22 is provided for connecting the power cable 50 that supplies the power from the power supply unit 5 to the light emitting element 21. Since the connector 22 has a shape and size for connecting the power cable 50, it protrudes from the light emitting element 21 toward the irradiation side.

取付部材３は、図３及び図４に示すように、例えば板金を折り曲げて凹形状に形成された構成である。具体的には、取付部材３は、光源部２が載置される平板で略正方形状の載置部３０と、載置部３０の一方の対向する端縁から略９０度折り曲げて形成された一対の脚部３１と、脚部３１の端縁から外方に向かって折り曲げられて形成され、ベース部４に固定される一対の固定片３２と、を有している。取付部材３は、ベース部４によって凹形状の開口面が塞がれている。取付部材３とベース部４とで囲まれた空間は、電源部５を収納するための電源収納部となる。 As shown in FIGS. 3 and 4, the mounting member 3 has, for example, a structure formed by bending a sheet metal into a concave shape. Specifically, the mounting member 3 is a flat plate on which the light source portion 2 is mounted, and is formed by bending the mounting portion 30 having a substantially square shape and the mounting portion 30 by substantially 90 degrees from one opposite end edge of the mounting portion 30. It has a pair of leg portions 31, and a pair of fixing pieces 32 that are formed by being bent outward from the edge of the leg portion 31 and fixed to the base portion 4. The concave opening surface of the mounting member 3 is closed by the base portion 4. The space surrounded by the mounting member 3 and the base portion 4 serves as a power supply accommodating portion for accommodating the power supply portion 5.

載置部３０の一側面には、光源部２が絶縁シート６を介して載置されている。一方、載置部３０の他側面には、電源部５が固定されている。なお、載置部３０は、図示した正方形状に限定されず、例えば長方形状又は多角形状でもよい。 A light source unit 2 is mounted on one side surface of the mounting portion 30 via an insulating sheet 6. On the other hand, the power supply unit 5 is fixed to the other side surface of the mounting unit 30. The mounting portion 30 is not limited to the square shape shown in the figure, and may be, for example, a rectangular shape or a polygonal shape.

載置部３０には、図４に示すように、光源部２を取り付けるための爪部３０ａが設けられている。爪部３０ａは、載置部３０の略中央において一端縁から他端縁に向かって一定の間隔を開けて４つ形成されている。爪部３０ａは、２つで１組とされており、一方の組と他方の組とが逆向きに形成され、それぞれ対応する光源部２の基板２０の一縁部に掛け止められる。また、載置部３０には、爪部３０ａに取り付けられた光源部２の位置を固定するための凸部３０ｂ及び凸部３０ｃが複数設けられている。凸部３０ｂは、光源部２の一方向（Ｙ方向）の動きを規制する位置に設けられている。凸部３０ｃは、爪部３０ａと共に光源部２の他方向（Ｘ方向）の動きを規制する位置に設けられている。 As shown in FIG. 4, the mounting portion 30 is provided with a claw portion 30a for attaching the light source portion 2. Four claw portions 30a are formed at substantially the center of the mounting portion 30 with a certain interval from one end edge to the other end edge. The claw portion 30a is made up of two sets, and one set and the other set are formed in opposite directions, and the claw portions 30a are hooked to one edge portion of the substrate 20 of the corresponding light source portion 2. Further, the mounting portion 30 is provided with a plurality of convex portions 30b and a plurality of convex portions 30c for fixing the position of the light source portion 2 attached to the claw portion 30a. The convex portion 30b is provided at a position that restricts the movement of the light source portion 2 in one direction (Y direction). The convex portion 30c is provided at a position that regulates the movement of the light source portion 2 in the other direction (X direction) together with the claw portion 30a.

また、載置部３０には、図４に示すように、カバー部７の一部が差し込まれる挿入孔３０ｄが４つ形成されている。挿入孔３０ｄは、一例として中央に２つ、脚部３１を設けた側の縁辺の近傍に１つずつ形成されている。また、載置部３０には、カバー部７を取り付けるために用いられるネジ等の締結部材９０を挿通させる締結孔３０ｅが、脚部３１を設けた側の縁辺の近傍に１つずつ形成されている。更に、載置部３０には、絶縁シート６を載置部３０に取り付けるために用いられるネジ等の締結部材９１を挿通させる締結孔３０ｆが、脚部３１を設けた側の縁辺の近傍に１つずつ形成されている。 Further, as shown in FIG. 4, the mounting portion 30 is formed with four insertion holes 30d into which a part of the cover portion 7 is inserted. As an example, two insertion holes 30d are formed in the center, and one insertion hole 30d is formed in the vicinity of the edge on the side where the leg portion 31 is provided. Further, in the mounting portion 30, fastening holes 30e through which fastening members 90 such as screws used for mounting the cover portion 7 are inserted are formed one by one in the vicinity of the edge on the side where the leg portion 31 is provided. There is. Further, in the mounting portion 30, a fastening hole 30f through which a fastening member 91 such as a screw used for attaching the insulating sheet 6 to the mounting portion 30 is inserted is provided in the vicinity of the edge on the side where the leg portion 31 is provided. They are formed one by one.

なお、爪部３０ａ、凸部３０ｂ及び凸部３０ｃの位置及び個数は、図示した構成に限定されず、各構成部材の大きさ及び形状に応じて、適宜変更して設けるものとする。また、締結孔３０ｅ及び３０ｆの位置及び個数は、図示した構成に限定されず、各構成部材の大きさ及び形状に応じて、適宜変更して設けるものとする。 The positions and numbers of the claw portions 30a, the convex portions 30b, and the convex portions 30c are not limited to the illustrated configuration, and may be appropriately changed and provided according to the size and shape of each constituent member. Further, the positions and the number of the fastening holes 30e and 30f are not limited to the illustrated configuration, and may be appropriately changed and provided according to the size and shape of each constituent member.

脚部３１は、図３及び図４に示すように、電源部５を収納する電源収納部を形成できる程度の高さを有している。固定片３２には、ネジ等の締結部材９２を挿通させる締結孔３２ａが形成されている。 As shown in FIGS. 3 and 4, the leg portion 31 has a height sufficient to form a power supply accommodating portion for accommodating the power supply unit 5. The fixing piece 32 is formed with a fastening hole 32a through which a fastening member 92 such as a screw is inserted.

ベース部４は、図３及び図４に示すように、平板状のプレートである。ベース部４は、平面を載置部３０に対向させて配置され、該平面に当接させた取付部材３の固定片３２とネジ等の締結部材９２で接合されている。なお、ベース部４は、例えばエレベータのかご又は室内の天井等に設けられたランプホルダーを外し、外した際に現れるネジ孔等のランプホルダー取付部に取り付けられる場合がある。 The base portion 4 is a flat plate as shown in FIGS. 3 and 4. The base portion 4 is arranged so that the flat surface faces the mounting portion 30, and is joined to the fixing piece 32 of the mounting member 3 that is in contact with the flat surface by a fastening member 92 such as a screw. The base portion 4 may be attached to a lamp holder mounting portion such as a screw hole that appears when the lamp holder provided in the elevator car or the ceiling in the room is removed, for example.

取付部材３は、側面側において、互いに対向する２つの脚部３１を有するとともに、互いに対向する開口部３３を有することになる。このように構成することで、開口部３３から自然対流が発生し、光源部２及び電源部５の放熱を行うことができる。 The mounting member 3 has two legs 31 facing each other on the side surface side, and has openings 33 facing each other. With this configuration, natural convection is generated from the opening 33, and heat can be dissipated from the light source unit 2 and the power supply unit 5.

電源部５は、光源部２に電力を供給する回路基板と、回路基板を収容する直方体形状の電源ケースと、を有している。電源部５は、図３及び図４に示すように、取付部材３とベース部４とで囲まれた空間である電源収納部に収納されている。電源部５は、電源ケーブル５０を介して、載置部３０に載置させた光源部２のコネクタ２２に接続されている。 The power supply unit 5 includes a circuit board that supplies electric power to the light source unit 2, and a rectangular parallelepiped power supply case that houses the circuit board. As shown in FIGS. 3 and 4, the power supply unit 5 is housed in a power supply storage unit which is a space surrounded by the mounting member 3 and the base unit 4. The power supply unit 5 is connected to the connector 22 of the light source unit 2 mounted on the mounting unit 30 via the power cable 50.

絶縁シート６は、光源部２と本体部１のその他の部分とを絶縁するために設けられている。また、絶縁シート６は、電源部５から光源部２側に引き込む電源ケーブル５０が、載置部３０の端縁と接触しないように保護できる形状で構成されている。電源ケーブル５０が載置部３０の端縁と接触して損傷する事態を防止するためである。また、絶縁シート６には、載置部３０に設けた爪部３０ａ、凸部３０ｂ及び凸部３０ｃ、カバー部７の構成部材、並びにネジ等の締結部材を通すための孔が複数形成されている。 The insulating sheet 6 is provided to insulate the light source portion 2 from the other portions of the main body portion 1. Further, the insulating sheet 6 is configured so that the power cable 50 drawn from the power supply unit 5 to the light source unit 2 side can be protected from contacting the edge of the mounting portion 30. This is to prevent the power cable 50 from coming into contact with the end edge of the mounting portion 30 and being damaged. Further, the insulating sheet 6 is formed with a plurality of holes for passing the claw portion 30a, the convex portion 30b and the convex portion 30c, the constituent members of the cover portion 7, and the fastening member such as a screw provided in the mounting portion 30. There is.

カバー部７は、図５に示すように、取付部材３と対向する側に開口面を有する凹形状であり、取付部材３に取り付けられて、光源部２を覆うものである。カバー部７は、図１〜図４に示すように、発光素子２１と対向する略正方形状の照射面部７０と、照射面部７０の周縁から取付部材３に向かって突き出し、取付部材３の周囲を囲う側面部７１と、を有している。 As shown in FIG. 5, the cover portion 7 has a concave shape having an opening surface on the side facing the mounting member 3, and is attached to the mounting member 3 to cover the light source portion 2. As shown in FIGS. 1 to 4, the cover portion 7 projects from the substantially square irradiation surface portion 70 facing the light emitting element 21 and the peripheral edge of the irradiation surface portion 70 toward the mounting member 3, and surrounds the mounting member 3. It has a side surface portion 71 that surrounds the surface.

照射面部７０は、図１に示すように、中央に形成された凸面部７ａによって２つの領域に区画されている。照射面部７０には、区画された各領域において、各発光素子２１に対向する複数の凸レンズ部８が設けられている。また、照射面部７０には、図５に示すように、凸レンズ部８を設けた位置に、発光素子２１からの光を凸レンズ部８に入光させるための貫通孔７２が複数形成されている。すなわち、貫通孔７２の部分に凸レンズ部８が配置されている。また、照射面部７０には、図１に示すように、本体部１に固定される固定部７ｂと、光源部２のコネクタ２２を収納するコネクタ収納部７ｃと、凸レンズ部８から照射された光を反射させるための傾斜面部７ｄと、が形成されている。照射面部７０は、図１及び図２に示すように、固定部７ｂ、コネクタ収納部７ｃ、及び傾斜面部７ｄによって、凸レンズ部８を設ける領域が取付部材３側に凹んだような形状となる。照明装置１００は、凹んだ部分に凸レンズ部８を収めることで、高さを低くすることができる。 As shown in FIG. 1, the irradiation surface portion 70 is divided into two regions by a convex surface portion 7a formed in the center. The irradiation surface portion 70 is provided with a plurality of convex lens portions 8 facing each light emitting element 21 in each of the partitioned regions. Further, as shown in FIG. 5, the irradiation surface portion 70 is formed with a plurality of through holes 72 for allowing the light from the light emitting element 21 to enter the convex lens portion 8 at the position where the convex lens portion 8 is provided. That is, the convex lens portion 8 is arranged in the portion of the through hole 72. Further, as shown in FIG. 1, the irradiation surface portion 70 has a fixed portion 7b fixed to the main body portion 1, a connector accommodating portion 7c for accommodating the connector 22 of the light source portion 2, and light emitted from the convex lens portion 8. An inclined surface portion 7d for reflecting the light source and the inclined surface portion 7d are formed. As shown in FIGS. 1 and 2, the irradiation surface portion 70 has a shape in which the region where the convex lens portion 8 is provided is recessed toward the mounting member 3 by the fixing portion 7b, the connector accommodating portion 7c, and the inclined surface portion 7d. The height of the illuminating device 100 can be lowered by accommodating the convex lens portion 8 in the recessed portion.

凸面部７ａは、照射面部７０の４つの縁辺のうち、一の縁辺から対向する他の縁辺に向かって長方形状に形成されている。凸面部７ａは、カバー部７の外面側が照射側に向かって突き出し、カバー部７の内面側が照射側に向かって窪むように形成されている。凸面部７ａの窪んだ部分には、載置部３０に設けられた爪部３０ａ、凸部３０ｂ及び凸部３０ｃが収納される。これにより、カバー部７を取付部材３に取り付けたときに、カバー部７の照射面部７０と、照射面側に突き出した爪部３０ａ、凸部３０ｂ及び凸部３０ｃとが干渉する事態を防いでいるので、照射面部７０と発光素子２１とを近づけることができ、照明装置１００の高さを低くすることができる。 The convex surface portion 7a is formed in a rectangular shape from one edge of the four edges of the irradiation surface 70 toward the other opposite edge. The convex surface portion 7a is formed so that the outer surface side of the cover portion 7 protrudes toward the irradiation side and the inner surface side of the cover portion 7 is recessed toward the irradiation side. The claw portion 30a, the convex portion 30b, and the convex portion 30c provided on the mounting portion 30 are housed in the recessed portion of the convex surface portion 7a. This prevents the irradiation surface portion 70 of the cover portion 7 from interfering with the claw portion 30a, the convex portion 30b, and the convex portion 30c protruding toward the irradiation surface side when the cover portion 7 is attached to the attachment member 3. Therefore, the irradiation surface portion 70 and the light emitting element 21 can be brought close to each other, and the height of the lighting device 100 can be lowered.

複数の凸レンズ部８は、光源部２の各発光素子２１に対向するように配置されている。凸レンズ部８は、一例として照射側が湾曲面とされ、発光素子２１と対向する面が窪んだ構成とされている。凸レンズ部８は、発光素子２１から発光され、貫通孔７２を通じて窪みに入光した光が広角になるように配光制御するものである。図示例の場合、凸レンズ部８は、凸面部７ａによって区画された各領域に２４個ずつ縦横に整列させて設けられている。 The plurality of convex lens portions 8 are arranged so as to face each light emitting element 21 of the light source portion 2. As an example, the convex lens portion 8 has a curved surface on the irradiation side and a recessed surface facing the light emitting element 21. The convex lens portion 8 controls the light distribution so that the light emitted from the light emitting element 21 and entering the recess through the through hole 72 has a wide angle. In the case of the illustrated example, 24 convex lens portions 8 are vertically and horizontally aligned in each region partitioned by the convex surface portions 7a.

固定部７ｂは、照射面部７０の４つの縁辺のうち、一方の対向する縁辺に隣接させて形成されている。固定部７ｂは、カバー部７の外面側が本体部１側に向かって窪み、カバー部７の内面側が本体部１側に向かって突き出すように段差を設けて形成されている。固定部７ｂには、締結部材９０が挿し込まれる挿通孔７３が形成されている。カバー部７は、固定部７ｂを取付部材３の載置部３０に当接させた状態で、挿通孔７３と締結孔３０ｅに締結部材９０を共通にねじ込んで締結することで、取付部材３に取り付けられる。 The fixed portion 7b is formed so as to be adjacent to one of the four edge edges of the irradiation surface portion 70, which is opposite to the other edge edge. The fixing portion 7b is formed by providing a step so that the outer surface side of the cover portion 7 is recessed toward the main body portion 1 side and the inner surface side of the cover portion 7 protrudes toward the main body portion 1 side. An insertion hole 73 into which the fastening member 90 is inserted is formed in the fixing portion 7b. The cover portion 7 is fastened to the mounting member 3 by screwing the fastening member 90 into the insertion hole 73 and the fastening hole 30e in a state where the fixing portion 7b is in contact with the mounting portion 30 of the mounting member 3. It is attached.

コネクタ収納部７ｃは、カバー部７の外面側が照射側に向かって突き出し、カバー部７の内面側が照射側に向かって窪むように形成されている。コネクタ収納部７ｃは、カバー部７を取付部材３に取り付けたときに、照射面部７０とコネクタ２２とが干渉する事態を防ぐために設けられている。コネクタ収納部７ｃは、コネクタ２２と対向する位置に形成されている。本実施の形態の場合、コネクタ収納部７ｃは、固定部７ｂと共に一方の対向する縁辺に隣接させて形成されている。本実施の形態に係る照明装置１００は、カバー部７を取付部材３に取り付けたときに、カバー部７の照射面部７０と、照射面側に突き出したコネクタ２２とが干渉する事態を防いでいるので、照射面部７０と発光素子２１とを近づけることができ、高さを低くすることができる。 The connector housing portion 7c is formed so that the outer surface side of the cover portion 7 protrudes toward the irradiation side and the inner surface side of the cover portion 7 is recessed toward the irradiation side. The connector accommodating portion 7c is provided to prevent the irradiation surface portion 70 and the connector 22 from interfering with each other when the cover portion 7 is attached to the attachment member 3. The connector accommodating portion 7c is formed at a position facing the connector 22. In the case of the present embodiment, the connector accommodating portion 7c is formed so as to be adjacent to one of the opposing edges together with the fixing portion 7b. The lighting device 100 according to the present embodiment prevents a situation in which the irradiation surface portion 70 of the cover portion 7 and the connector 22 protruding toward the irradiation surface side interfere with each other when the cover portion 7 is attached to the attachment member 3. Therefore, the irradiation surface portion 70 and the light emitting element 21 can be brought close to each other, and the height can be lowered.

傾斜面部７ｄは、照射面部７０の四隅に形成されている。傾斜面部７ｄは、カバー部７の外面側が照射側に向かって突き出し、カバー部７の内面側が照射側に向かって窪むように形成されている。傾斜面部７ｄは、照射面部７０の端縁から凸レンズ部８に向かって本体部１側に傾斜するように形成されている。傾斜面部７ｄを設けることにより、光源部２からの光を反射させ居室内に拡散させることができる。但し、傾斜面部７ｄは、光源部２からの光を反射させることができればよく、図示した形状及び位置に限定されない。 The inclined surface portions 7d are formed at the four corners of the irradiation surface portion 70. The inclined surface portion 7d is formed so that the outer surface side of the cover portion 7 protrudes toward the irradiation side and the inner surface side of the cover portion 7 is recessed toward the irradiation side. The inclined surface portion 7d is formed so as to be inclined toward the main body portion 1 from the edge of the irradiation surface portion 70 toward the convex lens portion 8. By providing the inclined surface portion 7d, the light from the light source portion 2 can be reflected and diffused in the living room. However, the inclined surface portion 7d is not limited to the shape and position shown in the drawing as long as it can reflect the light from the light source portion 2.

側面部７１は、カバー部７を取付部材３に取り付けたときに、取付部材３の脚部３１及び開口部３３と対向する。これにより、例えば振動等によってカバー部７が揺れても、脚部３１に突き当たる側面部７１によって、カバー部７の位置ずれを抑制することができる。 The side surface portion 71 faces the leg portion 31 and the opening 33 of the mounting member 3 when the cover portion 7 is attached to the mounting member 3. As a result, even if the cover portion 7 shakes due to vibration or the like, the position shift of the cover portion 7 can be suppressed by the side surface portion 71 that abuts on the leg portion 31.

また、図５に示すように、照射面部７０の内面側には、載置部３０に向かって突き出す突出部７４が４つ設けられている。突出部７４は、一例として照射面部７０の中央に２つ、一方の対向する側面部７１の近傍に１つずつ設けられている。突出部７４は、突出方向に向かって先細る円錐形状とされている。突出部７４は、取付部材３の載置部３０の挿入孔３０ｄに挿し込まれるものである。このとき、突出部７４は、基板２０の端縁に形成された貫通孔２０ａを通過して、基板２０を載置部３０に押さえ付けた状態で挿入孔３０ｄに挿入されて固定される。貫通孔２０ａの大きさは、突出部７４の先端部側よりも大きく、突出部７４の根元側よりも小さい。そのため、突出部７４は、水平方向（Ｘ方向及びＹ方向）と鉛直方向（Ｚ方向）において、基板２０を載置部３０に押さえ付けることができる。よって、本実施の形態に係る照明装置１００は、光源部２及びカバー部７が、挿入孔３０ｄに挿入した突出部７４によって、載置部３０に強固に固定されているので、振動を受けるような環境に設置した場合であっても、光源部２及びカバー部７が位置ずれを起こすことがなく、安定した既定配光を長期に亘って確保できる。 Further, as shown in FIG. 5, four projecting portions 74 protruding toward the mounting portion 30 are provided on the inner surface side of the irradiation surface portion 70. As an example, two projecting portions 74 are provided in the center of the irradiation surface portion 70, and one projecting portion 74 is provided in the vicinity of one of the opposing side surface portions 71. The protruding portion 74 has a conical shape that tapers in the protruding direction. The protruding portion 74 is inserted into the insertion hole 30d of the mounting portion 30 of the mounting member 3. At this time, the protruding portion 74 passes through the through hole 20a formed at the edge of the substrate 20, is inserted into the insertion hole 30d while the substrate 20 is pressed against the mounting portion 30, and is fixed. The size of the through hole 20a is larger than that of the tip end side of the protrusion 74 and smaller than that of the root side of the protrusion 74. Therefore, the projecting portion 74 can press the substrate 20 against the mounting portion 30 in the horizontal direction (X direction and Y direction) and the vertical direction (Z direction). Therefore, in the lighting device 100 according to the present embodiment, the light source portion 2 and the cover portion 7 are firmly fixed to the mounting portion 30 by the protruding portion 74 inserted into the insertion hole 30d, so that the lighting device 100 receives vibration. Even when the light source unit 2 and the cover unit 7 are installed in a suitable environment, the light source unit 2 and the cover unit 7 do not shift in position, and a stable default light distribution can be ensured for a long period of time.

なお、突出部７４は、図示した円錐形状に限定されず、円錐形状と多角錐形状とを組み合わせた形状、又は多角錐形状等、種々の形状で実施できる。また、突出部７４は、図示した位置又は個数に限定されず、各構成部材の大きさ及び形状に応じて、適宜変更して設けるものとする。 The protruding portion 74 is not limited to the illustrated conical shape, and can be implemented in various shapes such as a combination of a conical shape and a polygonal pyramid shape, or a polygonal pyramid shape. Further, the projecting portions 74 are not limited to the positions or the number shown in the drawings, and are appropriately modified and provided according to the size and shape of each constituent member.
