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 a lighting device.

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 unit connected to a side of the lamp so as to project therefrom. In such an illuminating device, there is a configuration in which one end side of the power supply unit is rotatably connected to the lamp so that it can be installed even when the height of 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 side of the power supply part is rotatably connected to the lamp, the power supply part can rotate more than the rotation range required for the lamp during the construction, so during the construction When handling a lighting device by holding the lamp or power supply, the power supply or lighting that you do not have may rotate unintentionally, causing the lighting device to drop with its force, or when it is installed in a hole such as a ceiling. There is a problem in that the workability is impaired, such as the lamp and the power supply part swinging greatly when it is embedded and it is difficult to operate.

Further, an overlapping portion 75 is extended on one end side of the cover top plate portion 71. The overlapping portion 75 is located above the cover surface 25a and in front of the edge of the cover surface 25a on the upper end side in the rotation range of the power supply unit 16 with respect to the lamp 15. The lower surface of the overlapping portion 75 is provided with an overlapping surface 75a that is opened and closed with respect to the cover surface 25a of the main body cover 25 of the lamp 15 by the rotation of the power supply unit 16.

カバー側板部72，73の一端側には、連結軸部31が挿通する回動孔76が形成されている。カバー側板部72，73は、電源ケース61の両側の外側に所定の間隙をあけて配置されている。そして、灯具15と電源部16との組立時に、電源ケース61の両側と電源カバー62の両側のカバー側板部72，73との間に放熱板24の側板部28，29の上端側が挿入され、連結軸部31がカバー側板部72，73の外側から回動孔76に挿通されて放熱板24の側板部28，29の取付孔30に取り付けられることにより、電源部16の一端側が灯具15に対して連結軸部31を中心に回動可能に連結されている。 A rotation hole 76 through which the connecting shaft portion 31 is inserted is formed at one end side of the cover side plate portions 72, 73. The cover side plate portions 72, 73 are arranged outside the both sides of the power supply case 61 with a predetermined gap. Then, at the time of assembling the lamp 15 and the power supply section 16, the upper end sides of the side plate sections 28, 29 of the heat dissipation plate 24 are inserted between both sides of the power supply case 61 and the cover side plate sections 72, 73 on both sides of the power cover 62, The connecting shaft portion 31 is inserted into the rotation hole 76 from the outside of the cover side plate portions 72, 73 and attached to the mounting holes 30 of the side plate portions 28, 29 of the heat dissipation plate 24, so that one end side of the power source portion 16 is attached to the lamp 15. On the other hand, it is rotatably connected around the connecting shaft portion 31.

一方の第１のカバー側板部72には、下方に突出する規制受部77が設けられている。規制受部77は、回動範囲規制部33の上方回動規制部33aの一部を構成するもので、電源部16の上方への回動時に放熱板24の第１の側板部28のねじ34に当接し、電源部16の上方への回動が規制される。また、カバー天板部71の下面は、回動範囲規制部33の下方回動規制部33bの一部を構成する規制受部78として構成されている。規制受部78は、電源部16の下方への回動時に放熱板24の第１の側板部28に設けられた規制突部35の上縁に当接し、電源部16の下方への回動が規制される。 The first cover side plate portion 72 is provided with a regulation receiving portion 77 that projects downward. The regulation receiving portion 77 constitutes a part of the upper rotation regulating portion 33a of the rotation range regulating portion 33, and is screwed to the first side plate portion 28 of the heat dissipation plate 24 when the power source portion 16 is rotated upward. It abuts against 34, and the upward rotation of the power supply unit 16 is restricted. Further, the lower surface of the cover top plate portion 71 is configured as a regulation receiving portion 78 that constitutes a part of the downward rotation regulating portion 33b of the rotation range regulating portion 33. The regulation receiving portion 78 contacts the upper edge of the regulation projection 35 provided on the first side plate portion 28 of the heat dissipation plate 24 when the power source portion 16 rotates downward, and the power source portion 16 rotates downward. Is regulated.

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。 Covers 79 that cover both sides of the terminal block 63 are provided at the other ends 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。 Further, the terminal block 63 has a terminal block body 81 and terminals housed in the terminal block 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 body 81 is formed in a rectangular box shape with an insulating material such as resin. One surface of the terminal block body 81 is configured as a connection surface 82 for connecting an electric wire from the standby power supply device, and the other opposite surface is configured as a mounting surface 83 to be mounted on the terminal block cover 64. The connection surface 82 of the terminal block body 81 is provided with a plurality of electric wire insertion holes 84 into which electric wires are inserted. The wire insertion hole 84 includes two for power input and two for feed wiring, for a total of four.

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。 Further, the terminal block cover 64 has a bottom plate portion 87, an inner plate portion 88 and an outer plate portion 89 that are bent above the bottom plate portion 87, is formed in a substantially U-shaped cross section, and is open on both sides. ing. The 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 that is attached to the cover top plate portion 71 of the power supply cover 62 with a screw 90 is bent and formed. Then, 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 side plate portion 89 and the cover top plate portion 71 are covered. An opening is made between the other end portion and the electric wire insertion hole 84 of the connection surface 82 of the terminal block 63 faces the opening portion.

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。 The 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 is placed 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。 Further, as the electric wire connecting the standby power supply device and the lighting device 10, for example, a fireproof cable in which a 2 mm single conductor wire is covered with a fireproof covering material is used.

次に、照明装置10の設置について説明する。 Next, the 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。 Pull out the electric wire from the standby power supply device from the embedding hole 12 of the ceiling plate 11, remove the coating material at the end of this electric wire to expose the conducting wire, and insert the end of this electric wire 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 side (terminal block 63 side) of the power supply unit 16 is directed upward, and the other end side 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 supply section 16 is inserted into the embedding hole 12 until the side surface (main body cover 26) of the lamp 15 is close to or abuts on the edge of the embedding hole 12, the mounting section 92 of the power supply section 16 faces downward. The power supply unit 16 is rotated to an area above the ceiling plate 11. Further, while rotating the lamp 15 together with the power supply unit 16, the upper side of the lamp 15 is inserted into the embedding hole 12. When the lamp 15 is rotated, since the inclined portion 38 is provided on the upper side of the lamp 15 on the opposite side to the arrangement direction of the power supply unit 16, the rotating lamp 15 is caught on the edge of the embedding hole 12. It can be inserted into the embedding hole 12 without any need.

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 the lamp 15 is inserted into the embedding hole 12, the pair of mounting springs 23 is pressed against the elastic body along the main body portion 20 of the lamp 15 in a folded state, and the pair of mounting springs 23 is The tip side is inserted 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 at positions aligned 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 dissipation plate 24. When the spring 23 is rotated upward and folded along the main body portion 20 of the lamp 15, since the spring 23 has a positional relationship that does not interfere with the connecting shaft portion 31, the spring 23 is folded close to the main body portion 20 of the lamp 15 and embedded. 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 portion 20 of the lamp 15 and the tip 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. Then, the lamp 15 is pulled up with respect to the ceiling plate 11 by unfolding to the upper side of the ceiling plate 11.

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。 The flange portion 51 of the decorative frame 22 of the lamp 15 that is pulled up with respect to the ceiling plate 11 contacts the lower surface of the ceiling plate 11, and 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。 Then, in the lighting device 10 embedded in the ceiling plate 11, one end side of the power supply unit 16 whose one end side is rotatably connected to the lamp 15 descends by its own weight, and the mounting unit 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 15, since the lighting device 10 must be supported by the ceiling plate 11 only by the mounting springs 23, three or more mounting springs 23 are required. However, since the other end of the power supply unit 16 is placed on the ceiling plate 11 by rotatably connecting the one end side of the power supply unit 16 to the lamp 15, the two mounting springs 23 allow the lamp 15 and the power supply to be connected. It is possible to support one end side of the portion 16, so that the configuration can be simplified, the number of parts can be reduced, and the workability can be improved.

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。 Further, if the connecting shaft portion 31 is located behind the lamp 15, the center of gravity is applied to the rear side and the lamp 15 is likely to tilt backward, but as in the present embodiment, the connecting shaft portion 31 is the central axis of the lamp 15. By being positioned so as to be substantially orthogonal to 17, the center of gravity can be balanced and the lamp 15 can be prevented from tilting.

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 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 included. Since the ceiling plate 11 receives the lamp, the mounting 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 to which the lighting power is supplied is turned on, and the light is applied to the illumination space through the lens 43.

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 at the time of lighting is transmitted to the heat radiating plate 24, further transmitted from the heat radiating plate 24 to the decorative frame 22, the body covers 25 and 26, and the like, and radiated 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。 Then, in the lighting device 10, the rotation range restricting unit 33 causes the upper surface of the power supply unit 16 to be located above the light source unit 40, and the lower surface of the power supply unit 16 to be located below the upper surface of the lighting unit 15, so that the lamp is 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 section 16 rotates upward with respect to the lamp 15, the regulation receiving section 77 of the power supply section 16 abuts on the screw 34 which is the upward rotation regulation section 33a and moves upward. Is restricted. If the upward rotation restricting portion 33a is not provided, the upper surface of the power source portion 16 is rotated in a clockwise direction which is higher than the position of the power source portion 16 shown in FIG. It will 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 section 16 rotates downward with respect to the lamp 15, the restriction receiving section 78 of the power supply section 16 is the downward rotation restriction section 33b, and the restriction projection 35 on the lamp 15 side. And the downward rotation is restricted. If the downward rotation restricting portion 33b is not provided, the upper surface of the power source portion 16 is lower than the light source portion (40) by making a large rotation in the counterclockwise direction below the position of the power source portion 16 shown in FIG. It turns 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 rotation range of the power supply unit 16 with respect to the lamp 15 is not restricted, when the lighting device 10 is handled with the lamp 15 or the power supply unit 16 at the time of construction, the power supply unit 16 or the lamp 15 on the side not having the lamp 15 or the power supply unit 16 is not restricted. Unintentionally turned so much that it dropped the lighting device 10 with its force, and when it was embedded in the embedding hole 12 of the ceiling plate 11, the lamp 15 and the power supply part 16 were shaken greatly and operated. It gets harder.

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 lighting device 10 of the present embodiment, the rotation range restricting portion 33 allows the upper surface of the power supply portion 16 to be located above the light source portion 40 and the lower surface of the power supply portion 16 to be located below the upper surface of the lamp 15. Since the rotation range of the power supply unit 16 with respect to the lamp 15 is restricted to a rotation range smaller than the unrestricted rotation range, the lighting device 10 is handled with the lamp 15 or the power supply unit 16 at the time of construction. At this time, since the power supply unit 16 or the lighting fixture 15 on the side not having it is unintentionally turned largely, the lighting device 10 may be dropped by its momentum, or when it is embedded in the embedding hole 12 of the ceiling board 11 and installed. It is possible to prevent the lamp 15 and the power supply unit 16 from swinging largely 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。 Further, the regulation of the rotation range of the power supply section 16 by the rotation regulation section 33 also accommodates the difference in the thickness dimension of the ceiling plate 11. Since the ceiling plate 11 generally has a size of 9 mm to 25 mm in general, it is possible to mount the other end side of the power supply unit 16 on the ceiling plate 11 even if the dimensions are as follows. It is regulated by the regulation of the moving range. That is, regarding the downward rotation range of the power supply unit 16 by the downward rotation restriction unit 33b, the upper surface of the flange portion 51 of the decorative frame 22 (the lower surface of the ceiling plate 11) and the mounting portion 92 of the power supply unit 16 are controlled. It is preferable that the height between them is slightly smaller than the minimum thickness dimension of the ceiling plate 11. When the thickness dimension of the ceiling plate 11 is 9 mm to 25 mm, it is preferably 9 mm or less. The upper rotation restricting portion 33a restricts the upper rotation range of the power supply section 16 by referring to the upper surface of the flange portion 51 of the decorative frame 22 (the lower surface of the ceiling plate 11) and the mounting portion 92 of the power supply section 16. The height between them is preferably larger than the maximum thickness dimension of the ceiling plate 11. When the thickness of the ceiling plate 11 is 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。 Further, since the power supply unit 16 is rotatably connected to the lamp 15, there are places where fingers are easily 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, on the one end side of the cover top plate portion 71, in the rotation range of the power supply portion 16 with respect to the lamp 15, it is located above the cover surface 25a and forward of the edge portion on the upper end side of the cover surface 25a. There is an overlapping portion 75 located. With this configuration, when the power supply section 16 is within the range of rotation with respect to the lamp 15, the overlapping section 75 is located in front of the upper end of the cover surface 25a, and therefore a finger is placed between the cover top plate section 71 and the cover surface 25a. It is 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 side of the power supply unit 16 is rotatably connected to the lamp 15, but the upper surface of the power supply unit 16 is the light source due to the rotation range restricting unit 33. Since the rotation range of the power supply section 16 with respect to the lamp 15 is regulated so that the lower surface of the power supply section 16 is located below the upper surface of the lamp 15 above the section 40, the lamp 15 is Alternatively, when the lighting device 10 is handled by holding the power supply unit 16, the power supply unit 16 or the lamp 15 on the side not having the power supply unit 16 unintentionally pivoted so much that the lighting device 10 is dropped by that momentum, or the ceiling plate. When embedded and installed in the embedding hole 12 of 11, it is possible to prevent the lamp 15 and the power supply unit 16 from largely shaking and becoming difficult to operate, and thus 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。 Further, since the connecting shaft portion 31 that rotatably connects one end side of the power supply section 16 to the lamp 15 is located on the central axis 17 of the lamp 15, the power supply section 16 is arranged so as to be closer to the lamp 15 side. Therefore, the length from the central axis 17 of the lamp 15 to the other end side of the power supply unit 16 can be shortened, the size can be reduced, and the construction can be easily performed even when the height of the ceiling is low during construction.

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。 Further, since the connecting shaft portion 31 is positioned so as to be substantially orthogonal to the central axis 17 of the lamp 15, the center of gravity can be balanced and the lamp 15 can be prevented from tilting.

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 at positions aligned along the axial direction of the lamp 15 with respect to the connecting shaft portions 31 arranged on the side plate portions 28, 29 on both sides of the heat dissipation plate 24. When 23 is rotated upward and folded along the main body portion 20 of the lamp 15, there is a positional relationship that does not interfere with the connecting shaft portion 31, that is, the connecting shaft portion 31 is folded along the lamp 15. Since the mounting springs 23 are arranged on the upper side in the axial direction of the lamp 15 than the tip side of the mounting springs 23, the pair of mounting springs 23 can be brought close to the main body portion 20 of the lamp 15 and can be folded, 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。 Further, the mass of the power supply unit 16 is larger than the mass of the lamp 15, but since one end side of the power supply unit 16 is rotatably connected to the lamp 15, it should be 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 the ceiling plate 11 receives a part of the mass of the power supply unit 16. 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。 Further, the power supply unit 16 is located at one end side of the cover top plate unit 71, above the cover surface 25a in the rotation range of the power supply unit 16 with respect to the lamp 15, and at the edge of the upper end side of the cover surface 25a. Since the overlapping portion 75 located on the front side is provided, it is possible to make it difficult to pinch a finger 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。 Further, the terminal block cover 64 can cover the terminal block 63 with the power supply cover 62, and can integrally have the function of the mounting portion 92 mounted on the ceiling plate 11.
