Description

本発明の実施形態は、照明装置に関する。 Embodiments of the present invention relate to lighting devices.

従来、天井などに埋め込み設置される照明装置は、灯具、およびこの灯具の側部に突出するように連結された電源部を備えている。このような照明装置では、天井裏の高さが少ない場合でも設置できるように、灯具に対して電源部の一端側が回動可能に連結された構成がある。 2. Description of the Related Art Conventionally, a lighting device embedded in a ceiling or the like includes a lamp and a power supply section connected to the side of the lamp so as to protrude. In such a lighting device, there is a configuration in which one end side of the power supply unit is rotatably connected to the lamp so that the lighting device can be installed even when the height of the space above the ceiling is small.

しかし、灯具に対して電源部の一端側が回動可能に連結された構成では、電源部が灯具に対して施工時に必要な回動範囲以上に大きく回動可能となっているため、施工時において、灯具または電源部を持って照明装置を取り扱う際、持ってない電源部または灯具が不用意に大きく回動したためにその勢いで照明装置を落してしまったり、また、天井などの埋込孔に埋め込み設置する際に灯具と電源部とが大きく振れて操作しにくいなど、施工性が損なわれる問題がある。 However, in the configuration in which one end of the power supply unit is rotatably connected to the lamp, the power supply unit can be rotated with respect to the lamp more than the required rotation range during construction. , When handling the lighting device by holding the lamp or power supply, the power supply or lamp that you do not have may be accidentally rotated too much, causing the lighting to drop due to the force of that force. There is a problem that the workability is impaired, for example, when the lamp and the power supply part shake greatly when embedded and installed, it is difficult to operate.

カバー側板部72，73の他端側には、端子台63の両側を覆う覆い部79が設けられている。 A cover portion 79 that covers both sides of the terminal block 63 is provided on the other end side of the cover side plate portions 72 and 73 .

また、端子台63は、端子台本体81、およびこの端子台本体81内に収納された端子を有している。 Also, the terminal block 63 has a terminal block main body 81 and terminals housed in the terminal block main body 81 .

端子台本体81は、例えば樹脂等の絶縁材料によって四角形箱状に形成されている。端子台本体81の一面が予備電源装置からの電線を接続する接続面82、反対の他面が端子台カバー64に取り付けられる取付面83として構成されている。端子台本体81の接続面82には、電線が挿入される複数の電線挿入孔84が設けられている。電線挿入孔84には、電源入力用に２つ、送り配線用に２つの合計４つが含まれる。 The terminal block main body 81 is formed in a rectangular box shape from an insulating material such as resin. One surface of the terminal block main body 81 is configured as a connection surface 82 for connecting wires from the standby power supply device, and the other opposite surface is configured as a mounting surface 83 to which the terminal block cover 64 is attached. A connection surface 82 of the terminal block main body 81 is provided with a plurality of wire insertion holes 84 into which wires are inserted. A total of four wire insertion holes 84 are included, two for power input and two for feed wiring.

また、端子台カバー64は、底板部87、この底板部87の上方に折曲された内側板部88および外側板部89を有し、断面略コ字形に形成されているとともに両側が開口されている。内側板部88と外側板部89との間に端子台63が配置され、内側板部88に端子台63が固定されている。内側板部88の上端には電源カバー62のカバー天板部71にねじ90で取り付けられる取付片部91が折曲形成されている。そして、端子台カバー64が電源カバー62に取り付けられた状態では、端子台カバー64の両側が電源カバー62の両側の覆い部79で覆われ、外側板部89の上端とカバー天板部71の他端部との間が開口され、この開口部分に端子台63の接続面82の電線挿入孔84が対向されている。 The terminal block cover 64 has a bottom plate portion 87, an inner plate portion 88 bent upward from the bottom plate portion 87, and an outer plate portion 89. The terminal block cover 64 has a substantially U-shaped cross section and is open on both sides. ing. A terminal block 63 is arranged between the inner plate portion 88 and the outer plate portion 89 , and the terminal block 63 is fixed to the inner plate portion 88 . At the upper end of the inner plate portion 88, a mounting piece portion 91 is bent to be mounted on the cover top plate portion 71 of the power supply cover 62 with screws 90. As shown in FIG. When the terminal block cover 64 is attached to the power supply cover 62, both sides of the terminal block cover 64 are covered with the cover portions 79 on both sides of the power supply cover 62, and the upper end of the outer plate portion 89 and the cover top plate portion 71 are separated from each other. An opening is provided between the terminal block 63 and the other end, and the wire insertion hole 84 of the connection surface 82 of the terminal block 63 faces this opening.

そして、端子台カバー64の底板部87と外側板部89とのなす角部は、照明装置10を天井板11に設置した際に天井板11の上面に載る載置部92として構成されている。 A corner formed by the bottom plate portion 87 and the outer plate portion 89 of the terminal block cover 64 is configured as a mounting portion 92 that rests on the upper surface of the ceiling plate 11 when the lighting device 10 is installed on the ceiling plate 11. .

また、予備電源装置と照明装置10とを接続する電線は、例えば２ｍｍの単線の導線を耐火性のある被覆材で被覆した耐火ケーブルが用いられている。 A fire-resistant cable in which a 2-mm single conductor wire is coated with a fire-resistant covering material is used as the electric wire for connecting the standby power supply device and the lighting device 10 .

次に、照明装置10の設置について説明する。 Next, installation of the lighting device 10 will be described.

天井板11の埋込孔12から予備電源装置からの電線を引き出し、この電線の先端の被覆材を除去して導線を露出させ、この電線の先端を端子台63の電線挿入孔84に挿入して接続する。 An electric wire from the standby power supply is pulled out from the embedding hole 12 of the ceiling plate 11, the covering material at the tip of the electric wire is removed to expose the electric wire, and the tip of the electric wire is inserted into the electric wire insertion hole 84 of the terminal block 63. to connect.

電源部16の他端側（端子台63側）を上方に向け、電源部16の他端側を埋込孔12に下方から挿入する。 The other end of the power supply unit 16 (terminal block 63 side) faces upward, and the other end of the power supply unit 16 is inserted into the embedding hole 12 from below.

灯具15の側面（本体カバー26）が埋込孔12の縁の近くまたは当接するまで電源部16が埋込孔12に挿入されたら、電源部16の載置部92が下方に向くように、電源部16を天井板11の上方域に回動させる。さらに、電源部16とともに灯具15を回動させながら、灯具15の上部側を埋込孔12に挿入する。灯具15を回動させる際、灯具15の上部側で電源部16の配置方向に対して反対側に傾斜部38が設けられているため、回動する灯具15が埋込孔12の縁に引っ掛かることなく、埋込孔12に挿入できる。 When the power source unit 16 is inserted into the embedding hole 12 until the side surface (main body cover 26) of the lamp 15 comes close to or abuts on the edge of the embedding hole 12, the mounting portion 92 of the power source unit 16 faces downward. The power supply unit 16 is rotated to the area above the ceiling plate 11 . Further, the upper part of the lamp 15 is inserted into the embedding hole 12 while rotating the lamp 15 together with the power supply unit 16 . When rotating the lamp 15, the inclined part 38 is provided on the upper side of the lamp 15 on the side opposite to the arrangement direction of the power supply unit 16, so that the rotating lamp 15 is caught on the edge of the embedding hole 12. can be inserted into the embedding hole 12 without

さらに、灯具15を埋込孔12に挿入する際には、一対の取付ばね23を弾性に抗して灯具15の本体部20に沿って折り畳んだ状態に押え付けながら、一対の取付ばね23の先端側を埋込孔12に挿入する。 Furthermore, when inserting the lamp fitting 15 into the embedding hole 12, the pair of mounting springs 23 are pressed against the elasticity of the pair of mounting springs 23 along the main body portion 20 of the lamp fitting 15 in a folded state. Insert the tip side into the embedding hole 12 .

このとき、一対の取付ばね23は、放熱板24の両側の側板部28，29に配置される連結軸部31に対して灯具15の軸方向に沿って並ぶ位置に配置されているが、取付ばね23が上方に回動されて灯具15の本体部20に沿って折り畳まれた際に、連結軸部31と干渉しない位置関係にあるため、灯具15の本体部20に近付けて折り畳まれ、埋込孔12に挿入可能とする。 At this time, the pair of mounting springs 23 are arranged along the axial direction of the lamp 15 with respect to the connecting shaft portions 31 arranged on the side plate portions 28 and 29 on both sides of the heat sink 24. When the spring 23 is rotated upward and folded along the body portion 20 of the lamp 15, it is in a positional relationship that does not interfere with the connecting shaft portion 31, so that it is folded close to the body portion 20 of the lamp 15 and buried. It can be inserted into the insertion hole 12.

灯具15の本体部20および一対の取付ばね23の先端側を埋込孔12に挿入した後、一対の取付ばね23の押え付けを解除することにより、一対の取付ばね23がばね力によって側方に展開して天井板11の上側に係合し、灯具15を天井板11に対して引き上げる。 After inserting the main body 20 of the lamp 15 and the distal ends of the pair of mounting springs 23 into the embedding hole 12, the pair of mounting springs 23 are released from the pressing force so that the pair of mounting springs 23 are laterally moved by the spring force. and engages with the upper side of the ceiling board 11 to pull up the lamp fixture 15 with respect to the ceiling board 11. - 特許庁

天井板11に対して引き上げられる灯具15の化粧枠22のフランジ部51が天井板11の下面に当接し、照明装置10の設置が完了する。 When the flange portion 51 of the decorative frame 22 of the lamp 15 that is lifted from the ceiling plate 11 abuts against the lower surface of the ceiling plate 11, the installation of the lighting device 10 is completed.

そして、天井板11に埋め込み設置された照明装置10では、一端側が灯具15に対して回動可能に連結されている電源部16の他端側が自重で下降し、電源部16の載置部92が天井板11の上面に載置される。したがって、照明装置10は、灯具15の一対の取付ばね23と電源部16の他端側の載置部92の３点で天井板11に支持されている。 In the lighting device 10 embedded in the ceiling plate 11, the other end of the power supply unit 16, one end of which is rotatably connected to the lamp fixture 15, descends under its own weight, and the mounting portion 92 of the power supply unit 16 is lowered. is placed on the upper surface of the ceiling plate 11. Therefore, the lighting device 10 is supported by the ceiling plate 11 at three points, the pair of mounting springs 23 of the lamp 15 and the mounting portion 92 on the other end side of the power source portion 16 .

ところで、電源部16が灯具15に固定されている場合には、取付ばね23のみによって照明装置10を天井板11に対して支持しなければならないため、３つ以上の取付ばね23を必要とするが、電源部16の一端側を灯具15に対して回動可能に連結することにより、電源部16の他端側が天井板11に載置されるため、２つの取付ばね23によって灯具15および電源部16の一端側を支持することが可能となり、構成の簡素化、部品点数の削減、および施工性を向上できる。 By the way, when the power supply unit 16 is fixed to the lamp fixture 15, the lighting device 10 must be supported on the ceiling plate 11 only by the mounting springs 23, so three or more mounting springs 23 are required. However, by rotatably connecting one end of the power supply unit 16 to the lamp 15, the other end of the power supply unit 16 is mounted on the ceiling plate 11, so that the two mounting springs 23 are attached to the lamp 15 and the power supply. It becomes possible to support one end side of the portion 16, thereby simplifying the configuration, reducing the number of parts, and improving workability.

さらに、仮に連結軸部31が灯具15の後方に位置する場合には重心が後方にかかり灯具15が後方に傾きやすくなるが、本実施形態のように、連結軸部31が灯具15の中心軸17に略直交するように位置することにより、重心のバランスがとれ、灯具15の傾きを防止できる。 Furthermore, if the connecting shaft portion 31 were positioned behind the lamp 15, the center of gravity would be shifted rearward and the lamp 15 would tend to tilt rearward. By being positioned so as to be substantially orthogonal to 17, the center of gravity can be balanced and tilting of the lamp 15 can be prevented.

しかも、電源部16の質量は灯具15の質量よりも大きい関係にあるが、電源部16の他端側が自重で下降して天井板11の上面に載置され、電源部16の質量の一部を天井板11で受けるため、灯具15を天井板11に取り付ける取付機構を簡素化できる。 Moreover, although the mass of the power supply unit 16 is larger than the mass of the lamp 15, the other end side of the power supply unit 16 descends by its own weight and is placed on the upper surface of the ceiling plate 11, so that part of the mass of the power supply unit 16 is reduced. is received by the ceiling plate 11, the attachment mechanism for attaching the lamp 15 to the ceiling plate 11 can be simplified.

また、予備電源装置からの外部電源が電線を通じて照明装置10の電源回路60に供給されると、電源回路60が外部電源を所定の点灯電源に変換して発光モジュール41に供給する。点灯電源が供給された発光モジュール41が点灯し、その光がレンズ43を通じて照明空間に照射される。 Further, when the external power supply from the standby power supply device is supplied to the power supply circuit 60 of the lighting device 10 through the electric wire, the power supply circuit 60 converts the external power supply into a predetermined lighting power supply and supplies it to the light emitting module 41 . The light emitting module 41 supplied with the lighting power is lit, and the light is emitted through the lens 43 to the illumination space.

点灯時に発光モジュール41が発生する熱は、放熱板24に伝達され、さらに、放熱板24から化粧枠22および本体カバー25，26等に伝達され、これらから空気中に放熱される。 The heat generated by the light-emitting module 41 during lighting is transferred to the radiator plate 24, further transferred from the radiator plate 24 to the decorative frame 22, the main body covers 25 and 26, and the like, and radiated from these into the air.

そして、照明装置10では、回動範囲規制部33により、電源部16の上面が光源部40よりも上方であり、電源部16の下面が灯具15の上面よりも下方に位置するように、灯具15に対する電源部16の回動範囲を、未規制時の回動範囲よりも小さい回動範囲に規制している。 In the lighting device 10, the turning range restricting portion 33 controls the lamp so that the upper surface of the power supply portion 16 is positioned above the light source portion 40 and the lower surface of the power supply portion 16 is positioned below the upper surface of the lamp 15. The rotation range of the power supply unit 16 with respect to 15 is restricted to a rotation range smaller than the rotation range when not restricted.

すなわち、図４に示すように、灯具15に対して電源部16が上方に回動する場合、電源部16の規制受部77が上方回動規制部33aであるねじ34に当接し、上方への回動が規制される。上方回動規制部33aが無い場合には、図４に示す電源部16の位置よりも上方である時計回り方向に大きく回動し、電源部16の下面が灯具15の上面よりも上方に回動してしまう。 That is, as shown in FIG. 4, when the power supply unit 16 rotates upward with respect to the lamp 15, the regulation receiving portion 77 of the power supply unit 16 contacts the screw 34, which is the upward rotation restricting portion 33a, and rotates upward. rotation is regulated. In the absence of the upward rotation restricting portion 33a, the power supply unit 16 is rotated largely clockwise, which is higher than the position of the power supply unit 16 shown in FIG. move.

一方、図５に示すように、灯具15に対して電源部16が下方に回動する場合、電源部16の規制受部78が下方回動規制部33bである灯具15側の規制突部35に当接し、下方への回動が規制される。下方回動規制部33bが無い場合には、図５に示す電源部16の位置よりも下方である反時計回り方向に大きく回動し、電源部16の上面が光源部（40）よりも下方に回動してしまう。 On the other hand, as shown in FIG. 5, when the power supply unit 16 rotates downward with respect to the lamp 15, the regulation receiving part 78 of the power supply unit 16 is the downward rotation regulation part 33b. and its downward rotation is restricted. In the absence of the downward rotation restricting portion 33b, the power source portion 16 rotates greatly in the counterclockwise direction, which is below the position of the power source portion 16 shown in FIG. It will rotate to

仮に、灯具15に対する電源部16の回動範囲が未規制であると、施工時において、灯具15または電源部16を持って照明装置10を取り扱う際、持っていない側の電源部16または灯具15が不用意に大きく回動したためにその勢いで照明装置10を落してしまったり、また、天井板11の埋込孔12に埋め込み設置する際に灯具15と電源部16とが大きく振れて操作しにくくなる。 If the turning range of the power supply unit 16 with respect to the lamp 15 is not restricted, when handling the lighting device 10 with the lamp 15 or the power supply unit 16 during construction, the power supply unit 16 or the lamp 15 on the side that is not held may be uncontrolled. Illumination device 10 was dropped due to the force of the unintentional large rotation, or the lighting device 15 and power supply unit 16 shook greatly when they were embedded in the embedding hole 12 of the ceiling plate 11 and operated. become difficult.

本実施形態の照明装置10では、回動範囲規制部33により、電源部16の上面が光源部40よりも上方であり、電源部16の下面が灯具15の上面よりも下方に位置するように、灯具15に対する電源部16の回動範囲を未規制時の回動範囲よりも小さい回動範囲に規制しているため、施工時において、灯具15または電源部16を持って照明装置10を取り扱う際、持っていない側の電源部16または灯具15が不用意に大きく回動したためにその勢いで照明装置10を落してしまったり、また、天井板11の埋込孔12に埋め込み設置する際に灯具15と電源部16とが大きく振れて操作しにくくなるのを防止可能とする。 In the illumination device 10 of the present embodiment, the rotation range restricting portion 33 positions the upper surface of the power source portion 16 above the light source portion 40 and the lower surface of the power source portion 16 below the upper surface of the lamp 15. , the rotation range of the power supply unit 16 with respect to the lamp 15 is regulated to a smaller rotation range than the unregulated rotation range. At that time, the power supply unit 16 or the lighting device 15 on the side that is not held inadvertently pivoted greatly, causing the illuminating device 10 to drop due to the momentum. To prevent a lamp fixture 15 and a power supply part 16 from swinging greatly and becoming difficult to operate.

また、回動規制部33による電源部16の回動範囲の規制は、天井板11の厚み寸法の違いにも対応している。天井板11は、一般的に９ｍｍ～２５ｍｍであることが多いため、とのような寸法でも、電源部16の他端側を天井板11上に載置することが可能な電源部16の回動範囲の規制に規制している。すなわち、下方回動規制部33bによる電源部16の下方への回動範囲の規制については、化粧枠22のフランジ部51の上面（天井板11の下面）と電源部16の載置部92との間の高さが、天井板11の最小厚み寸法よりも少し小さい程度が好ましい。天井板11の厚み寸法が９ｍｍ～２５ｍｍである場合には、９ｍｍ以下とすることが好ましい。また、上方回動規制部33aによる電源部16の上方への回動範囲の規制については、化粧枠22のフランジ部51の上面（天井板11の下面）と電源部16の載置部92との間の高さが、天井板11の最大厚み寸法よりも大きいことが好ましい。天井板11の厚み寸法が９ｍｍ～２５ｍｍである場合には、２５ｍｍ以上とすることが好ましい。 In addition, the restriction of the rotation range of the power supply unit 16 by the rotation restricting part 33 also corresponds to the difference in the thickness dimension of the ceiling plate 11 . Since the ceiling plate 11 is generally 9 mm to 25 mm in many cases, the power supply unit 16 can be mounted on the ceiling plate 11 with the other end side of the power supply unit 16 even with such a dimension. It is regulated by the regulation of the range of motion. That is, regarding the regulation of the downward rotation range of the power supply unit 16 by the downward rotation control part 33b, the upper surface of the flange part 51 of the decorative frame 22 (the lower surface of the ceiling plate 11) and the mounting part 92 of the power supply part 16 It is preferable that the height between them is slightly smaller than the minimum thickness dimension of the ceiling plate 11 . When the ceiling plate 11 has a thickness of 9 mm to 25 mm, it is preferably 9 mm or less. Regarding the restriction of the upward rotation range of the power supply unit 16 by the upward rotation restricting part 33a, the upper surface of the flange part 51 of the decorative frame 22 (the lower surface of the ceiling plate 11) and the mounting part 92 of the power supply part 16 It is preferable that the height between the two is larger than the maximum thickness dimension of the ceiling plate 11 . When the ceiling plate 11 has a thickness of 9 mm to 25 mm, it is preferably 25 mm or more.

また、電源部16を灯具15に対して回動可能に連結しているため、指が挟まりやすい箇所が生じる。具体的には、カバー天板部71の一端側と灯具15の本体カバー25との間がある。そこで、カバー天板部71の一端側に、灯具15に対する電源部16の回動範囲において、カバー面25aよりも上方側に位置し、かつカバー面25aの上端側の縁部よりも前方側に位置する重なり部75を設けている。この構成により、灯具15に対する電源部16の回動範囲内であれば、重なり部75がカバー面25aの上端よりも前方にあるため、カバー天板部71とカバー面25aとの間に指を挟みにくい。 In addition, since the power supply unit 16 is rotatably connected to the lamp 15, there are places where fingers are likely to be caught. Specifically, there is a space between one end of the cover top plate portion 71 and the main body cover 25 of the lamp 15 . Therefore, in the range of rotation of the power supply unit 16 with respect to the lamp 15, the cover top plate portion 71 is positioned above the cover surface 25a and forward of the edge of the upper end of the cover surface 25a. A positioned overlapping portion 75 is provided. With this configuration, within the range of rotation of the power supply unit 16 with respect to the lamp 15, the overlapped portion 75 is located forward of the upper end of the cover surface 25a, so a finger can be placed between the cover top plate portion 71 and the cover surface 25a. Hard to pinch.

このように、本実施形態の照明装置10では、灯具15に対して電源部16の一端側を回動可能に連結しているが、回動範囲規制部33により、電源部16の上面が光源部40よりも上方であり、電源部16の下面が灯具15の上面よりも下方に位置するように、灯具15に対する電源部16の回動範囲を規制しているため、施工時において、灯具15または電源部16を持って照明装置10を取り扱う際、持っていない側の電源部16または灯具15が不用意に大きく回動したためにその勢いで照明装置10を落してしまったり、また、天井板11の埋込孔12に埋め込み設置する際に灯具15と電源部16とが大きく振れて操作しにくくなるのを防止でき、施工性を向上できる。 As described above, in the lighting device 10 of the present embodiment, one end of the power supply unit 16 is rotatably connected to the lamp 15. Since the rotation range of the power supply unit 16 with respect to the lamp 15 is regulated so that the lower surface of the power supply unit 16 is positioned lower than the upper surface of the lamp 15, the lamp 15 is located above the unit 40 during construction. Alternatively, when handling the lighting device 10 while holding the power supply unit 16, the power supply unit 16 or the lighting device 15 on the side that is not held inadvertently rotates greatly, causing the lighting device 10 to drop due to that force. When embedded in the embedding hole 12 of 11, it is possible to prevent the lamp 15 and the power supply unit 16 from swinging greatly and becoming difficult to operate, and the workability can be improved.

また、灯具15に対して電源部16の一端側を回動可能に連結する連結軸部31は、灯具15の中心軸17上に位置するため、電源部16を灯具15側に寄せるように配置でき、灯具15の中心軸17から電源部16の他端側までの長さを短くでき、小形化できるとともに、施工時に天井裏の高さが低い場合でも容易に施工することができる。 In addition, since the connecting shaft portion 31 that rotatably connects one end side of the power source portion 16 to the lamp device 15 is located on the central axis 17 of the lamp device 15, the power source portion 16 is arranged to be closer to the lamp device 15 side. The length from the central axis 17 of the lamp 15 to the other end side of the power supply section 16 can be shortened, and the size can be reduced.

さらに、連結軸部31が灯具15の中心軸17に略直交するように位置するため、重心のバランスがとれ、灯具15の傾きを防止できる。 Furthermore, since the connecting shaft portion 31 is positioned substantially perpendicular to the central axis 17 of the lamp 15, the center of gravity is balanced and the inclination of the lamp 15 can be prevented.

また、一対の取付ばね23は、放熱板24の両側の側板部28，29に配置される連結軸部31に対して灯具15の軸方向に沿って並ぶ位置に配置されているが、取付ばね23が上方に回動されて灯具15の本体部20に沿って折り畳まれた際に、連結軸部31と干渉しない位置関係にあるため、すなわち、連結軸部31は、灯具15に沿って折り畳まれる取付ばね23の先端側よりも灯具15の軸方向の上方側に配置されているため、一対の取付ばね23を灯具15の本体部20に近付けて折り畳むことができ、埋込孔12に容易に挿入することができる。 Also, the pair of mounting springs 23 are arranged along the axial direction of the lamp 15 with respect to the connecting shaft portions 31 arranged on the side plate portions 28 and 29 on both sides of the heat sink 24. When 23 is rotated upward and folded along main body 20 of lamp 15, it is in a positional relationship that does not interfere with connecting shaft 31. That is, connecting shaft 31 is folded along lamp 15. Since the pair of mounting springs 23 are arranged on the upper side in the axial direction of the lamp 15 than the distal ends of the mounting springs 23 attached to the mounting springs 23, the pair of mounting springs 23 can be folded closer to the main body 20 of the lamp 15, and can be easily inserted into the embedding hole 12. can be inserted into

また、電源部16の質量は灯具15の質量よりも大きい関係にあるが、灯具15に対して電源部16の一端側を回動可能に連結しているため、天井板11に埋め込み設置することにより、電源部16の他端側が自重で下降して天井板11の上面に載置され、電源部16の質量の一部を天井板11で受けるため、灯具15を天井板11に取り付ける取付機構を簡素化できる。 In addition, although the mass of the power supply unit 16 is larger than the mass of the lamp 15, since one end of the power supply unit 16 is rotatably connected to the lamp 15, it can be installed embedded in the ceiling plate 11. As a result, the other end of the power supply unit 16 descends by its own weight and is placed on the upper surface of the ceiling plate 11, and a part of the mass of the power supply unit 16 is received by the ceiling plate 11. Therefore, a mounting mechanism for attaching the lamp 15 to the ceiling plate 11 can be simplified.

また、電源部16は、カバー天板部71の一端側に、灯具15に対する電源部16の回動範囲において、カバー面25aよりも上方側に位置し、かつカバー面25aの上端側の縁部よりも前方側に位置する重なり部75を設けているため、カバー天板部71とカバー面25aとの間に指を挟みにくくできる。 In addition, the power supply unit 16 is located on one end side of the cover top plate portion 71, above the cover surface 25a in the rotation range of the power supply unit 16 with respect to the lamp fixture 15, and is located at the edge of the upper end side of the cover surface 25a. Since the overlapping portion 75 is provided on the front side, it is possible to prevent fingers from being caught between the cover top plate portion 71 and the cover surface 25a.

また、端子台カバー64は、電源カバー62との間で端子台63を覆うことができ、天井板11上に載置される載置部92の機能を一体に備えることができる。 In addition, the terminal block cover 64 can cover the terminal block 63 between itself and the power supply cover 62, and can integrally have the function of the mounting portion 92 mounted on the ceiling plate 11. FIG.
