Description

本発明の実施形態は、被設置面に取り付けられる照明装置に関する。 Embodiments of the present invention relate to a lighting device mounted on a surface to be installed.

従来、天井等の被設置面に取り付けられる直付形の照明装置では、光源部、電源部および端子台等が一体的に配置された器具本体が被設置面に取り付けられ、この器具本体をカバーで覆う構成がある。天井から照明装置に引き込まれる電線は、端子台に接続されるが、例えばＦケーブル等の場合には曲がりにくいため、照明装置の内部スペースを引き回すようにして端子台に接続されている。 Conventionally, in a direct-mounted lighting device that is attached to a surface to be installed such as a ceiling, a device body in which a light source unit, a power supply unit, a terminal block, etc. are integrally arranged is attached to the surface to be installed, and the device body is covered. There is a configuration to cover with. The electric wire drawn from the ceiling to the lighting device is connected to the terminal block, but in the case of, for example, an F cable or the like, it is difficult to bend, so it is connected to the terminal block so as to route the internal space of the lighting device.

このような照明装置では小形化の要求がある。しかし、照明装置を小形化すると、内部スペースが小さくなって電線の引き回しが難しくなり、施工性しにくくなるため、小形化への対応が難しい。 There is a demand for miniaturization in such an illumination device. However, when the lighting device is downsized, the internal space becomes small, and it becomes difficult to route the electric wire, and it becomes difficult to construct the lighting device. Therefore, it is difficult to cope with the downsizing.

In addition, the mounting surface 65 of the terminal block body 63 is provided with positioning projections which are inserted into the pair of positioning holes 60b of the power supply cover 56 and the pair of positioning holes 43b of the heat dissipation plate 32 for positioning, and the power supply cover. A mounting hole into which a screw 61 inserted through the insertion hole 60a of 56 is screwed is provided. The terminal block 35 is attached to the terminal block attachment portion 60 of the power supply cover 56, and is arranged on one side in the lateral direction on the upper surface side of the power supply portion 34. The head of the screw 61 is arranged in the insertion groove 43a of the heat dissipation plate 32. Then, the wire insertion hole 66 of the terminal block 35 arranged on one side in the lateral direction on the upper surface side of the power source section 34 is directed to the other side in the lateral direction of the power source section 34. Therefore, the insertion direction of the electric wire 12 into the electric wire insertion hole 66 of the terminal block 35 is a direction intersecting the central axis 18, and is a direction from the other side in the lateral direction of the power supply unit 34 to the one side.

端子台本体63内に収納される端子は、各電線挿入孔66の内側に配置され、各電線挿入孔66に挿入される電線12に電気的に接続される。そして、端子台35の端子は、内部配線によって電源部34の電源回路53に電気的に接続されている。 The terminals housed in the terminal block body 63 are arranged inside the electric wire insertion holes 66 and are electrically connected to the electric wires 12 inserted into the electric wire insertion holes 66. The terminals of the terminal block 35 are electrically connected to the power supply circuit 53 of the power supply unit 34 by internal wiring.

そして、予備電源装置と照明装置10とを接続する電線12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。この耐火ケーブルは、硬く、小半径に曲がりにくい特性を有している。 The electric wire 12 that connects the standby power supply device and the lighting device 10 is, for example, a fireproof cable in which a 2 mm single conductor wire is covered with a fireproof covering material. This fireproof cable has the characteristics of being hard and not easily bent in a small radius.

このような電線12を、照明装置10の内部スペースを引き回して端子台35に接続可能とするために、照明装置10内での端子台35の位置が設定されている。すなわち、端子台35は、図１に示すように、端子台本体63の接続面64の中央部（中心部）ｓであって電線挿入孔66の軸方向前方（接続面64の前方）から見て中央部（中心部）ｓを通る中心線s1が、中心軸18からの取付孔26の取付ピッチL1の位置よりも外側となる距離L2に位置するように、本体部16（電源部34）に配置されている。さらに、端子台35は、端子台本体63の一部が取付部材15の取付ピッチL1の位置よりも内側に位置するように本体部16に配置されている。さらに、取付部材15の取付板部21とこの取付板部21に対向する端子台35の面との対向方向の離間距離L3が、その対向方向に沿った端子台35の長さL4よりも小さい関係にある。離間距離L3は、１４ｍｍ以下が好ましい。さらに、取付部材15の取付板部21とこの取付板部21に対向する端子台35の面に対して反対側の面との間の距離L5は、中心軸18と端子台35の接続面64の中央部ｓとの間の距離L2よりも小さい関係にある。そして、この端子台35の位置では、端子台35の電線挿入孔66の軸方向前方には、放熱板32（第２のアーム部40）および本体取付部22が配置されず、開放されている。 The position of the terminal block 35 in the lighting device 10 is set so that the electric wire 12 can be connected to the terminal block 35 by routing the internal space of the lighting device 10. That is, as shown in FIG. 1, the terminal block 35 is viewed from an axial front side (front side of the connection surface 64) of the wire insertion hole 66, which is the central portion (center portion) s of the connection surface 64 of the terminal block body 63. So that the center line s1 passing through the central portion (central portion) s is located at a distance L2 that is outside the position of the mounting pitch L1 of the mounting holes 26 from the central shaft 18 (the power supply unit 34). It is located in. Further, the terminal block 35 is arranged in the main body portion 16 such that a part of the terminal block main body 63 is located inside the position of the mounting pitch L1 of the mounting member 15. Further, the distance L3 in the facing direction between the mounting plate portion 21 of the mounting member 15 and the surface of the terminal block 35 facing the mounting plate portion 21 is smaller than the length L4 of the terminal block 35 along the facing direction. In a relationship. The distance L3 is preferably 14 mm or less. Further, the distance L5 between the mounting plate portion 21 of the mounting member 15 and the surface opposite to the surface of the terminal block 35 facing the mounting plate portion 21 is determined by the connecting surface 64 of the central shaft 18 and the terminal block 35. Is smaller than the distance L2 from the central portion s of the. At the position of the terminal block 35, the heat dissipation plate 32 (second arm part 40) and the main body mounting part 22 are not arranged in the axial direction forward of the wire insertion hole 66 of the terminal block 35 and are open. ..

次に、図１および図２に示すように、カバー17は、上面側が開口された有底の円筒状に形成されている。カバー17の下面中央には、レンズ47が突出する窓孔69が形成されている。カバー17の周面上部側には、周方向の対称位置に一対の挿通孔70が設けられているとともに、一方の挿通孔70の側部にカバー17の内方に突出する位置決め突部71が突設されている。位置決め突部71が取付部材15のカバー取付部23の側縁に当接した状態で挿通孔70がカバー取付部23の取付孔23aと同軸に配置されるように位置決めされる。そして、挿通孔70を挿通してカバー取付部23の取付孔23aに螺着されるねじ72により、カバー17が取付部材15に取り付けられる。カバー17の取付状態では、カバー17の上端部は、取付部材15の取付板部21よりも下方に位置し、被設置面11との間に通気用の隙間73が設けられる。 Next, as shown in FIGS. 1 and 2, the cover 17 is formed in a bottomed cylindrical shape having an opening on the upper surface side. A window hole 69 through which the lens 47 projects is formed in the center of the lower surface of the cover 17. On the upper side of the peripheral surface of the cover 17, a pair of insertion holes 70 are provided at symmetrical positions in the circumferential direction, and a positioning protrusion 71 projecting inward of the cover 17 is provided on the side of one of the insertion holes 70. It is projected. The insertion hole 70 is positioned so that the insertion hole 70 is arranged coaxially with the mounting hole 23a of the cover mounting portion 23 in a state where the positioning protrusion 71 is in contact with the side edge of the cover mounting portion 23 of the mounting member 15. Then, the cover 17 is attached to the attachment member 15 by the screw 72 that is inserted through the insertion hole 70 and screwed into the attachment hole 23a of the cover attachment portion 23. In the mounted state of the cover 17, the upper end of the cover 17 is located below the mounting plate portion 21 of the mounting member 15, and a ventilation gap 73 is provided between the cover 17 and the mounting surface 11.

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.

被設置面11から引き出されている電線12を取付部材15の配線孔24に通し、取付部材15の取付孔25，26を通じてねじで取り付ける。このとき、取付部材15は本体部16と分離されており、取付部材15のみを容易に設置できる。 The electric wire 12 pulled out from the surface 11 to be installed is passed through the wiring hole 24 of the mounting member 15, and is mounted by screws through the mounting holes 25 and 26 of the mounting member 15. At this time, the mounting member 15 is separated from the main body portion 16, and only the mounting member 15 can be easily installed.

電線12の先端の被覆材を除去して導線を露出させ、この電線12の先端を本体部16の端子台35の電線挿入孔66に挿入して接続する。このとき、本体部16は、取付部材15と分離されているため、端子台35の接続面64の前方域が大きく開放されており、電線挿入孔66に対する電線12の挿入接続操作を容易に行うことができる。 The covering material at the tip of the electric wire 12 is removed to expose the conducting wire, and the tip of the electric wire 12 is inserted into the electric wire insertion hole 66 of the terminal block 35 of the main body 16 for connection. At this time, since the main body portion 16 is separated from the mounting member 15, the front area of the connection surface 64 of the terminal block 35 is largely opened, and the operation of inserting and connecting the electric wire 12 into the electric wire insertion hole 66 is easily performed. be able to.

続いて、本体部16を取付部材15に取り付ける。このとき、本体部16の放熱板32の各アーム部39，40にそれぞれ螺着されているねじ42は、ねじ42の頭部42aが各アーム部39，40の外面から離れ、ねじ42の頭部42aと各アーム部39，40の外面との間にねじ部42bが露出するように、各アーム部39，40に対して所定の螺着位置よりも緩めた状態とする。 Then, the body portion 16 is attached to the attachment member 15. At this time, in the screw 42 screwed to each arm portion 39, 40 of the heat dissipation plate 32 of the main body portion 16, the head 42a of the screw 42 separates from the outer surface of each arm portion 39, 40, and The threaded portion 42b is exposed between the portion 42a and the outer surfaces of the arm portions 39, 40 so that the threaded portion 42b is exposed to the arm portions 39, 40 and is loosened from a predetermined screwing position.

本体部16を取付部材15に取り付けるには、まず、各アーム部39，40の上端を取付部材15の各本体取付部22の内側間に嵌め込み、各ねじ42のねじ部42bを各本体取付部22の溝部28に進入させる。このとき、所定の螺着位置よりも緩められているねじ42の頭部42aは、引掛り部29の外側を通過して上方に移動する。なお、ねじ42の緩め方が足りなかった場合、ねじ42の頭部42aが引掛り部29に当接するが、引掛り部29は取付方向ａへ向けて傾斜状に設けられているため、ねじ42の頭部42aが引掛り部29を乗り越えて上方に移動しやすい。 To attach the body portion 16 to the attachment member 15, first, the upper ends of the arm portions 39 and 40 are fitted between the insides of the body attachment portions 22 of the attachment member 15, and the screw portions 42b of the screws 42 are attached to the body attachment portions. Enter the groove 28 of 22. At this time, the head portion 42a of the screw 42, which is loosened from the predetermined screwing position, passes over the outside of the hook portion 29 and moves upward. If the screw 42 is not loosened sufficiently, the head 42a of the screw 42 abuts the catch 29, but the catch 29 is inclined toward the mounting direction a. It is easy for the head 42a of 42 to get over the catch 29 and move upward.

なお、ねじ42の所定の螺着位置とは、一対のねじ42の頭部42a間の間隔が一対の本体取付部22の引掛り部29の間隔と同じとなる位置である。そのため、ねじ42が所定の螺着位置よりも緩められた状態とは、一対のねじ42の頭部42a間の間隔が一対の本体取付部22の引掛り部29の間隔よりも広い状態である。また、ねじ42が所定の螺着位置よりも締め付けられた状態とは、一対のねじ42の頭部42a間の間隔が一対の本体取付部22の引掛り部29の間隔よりも狭い状態である。ねじ42が所定の螺着位置よりも締め付けられた状態には、ねじ42が強く締め付けられ、ねじ42の頭部42aとアーム部39，40との間で取付部材15の本体取付部22を挟み込んで保持している状態、およびねじ42が少し緩められている状態が含まれる。 The predetermined screwing position of the screw 42 is a position where the distance between the head portions 42a of the pair of screws 42 is the same as the distance between the hook portions 29 of the pair of main body mounting portions 22. Therefore, the state in which the screw 42 is loosened from the predetermined screwing position is a state in which the distance between the head portions 42a of the pair of screws 42 is wider than the distance between the hook portions 29 of the pair of main body mounting portions 22. .. Further, the state in which the screw 42 is tightened from the predetermined screwing position is a state in which the interval between the head portions 42a of the pair of screws 42 is narrower than the interval between the hooking portions 29 of the pair of main body mounting portions 22. .. When the screw 42 is tightened beyond the predetermined screwing position, the screw 42 is strongly tightened, and the main body mounting portion 22 of the mounting member 15 is sandwiched between the head portion 42a of the screw 42 and the arm portions 39, 40. And a state in which the screw 42 is slightly loosened.

本体部16を取付部材15に取り付ける際、被設置面11から引き出されている電線12の余分な長さ分を取付部材15の配線孔24を通じて被設置面11の内側に戻しながら、配線孔24と端子台35との間の電線12を取付部材15と本体部16との間のスペースに収まるように引き回しながら配置する。 When the main body 16 is attached to the mounting member 15, the excess length of the electric wire 12 pulled out from the installation surface 11 is returned to the inside of the installation surface 11 through the wiring hole 24 of the installation member 15 while the wiring hole 24 The electric wire 12 between the terminal block 35 and the terminal block 35 is arranged while being drawn so as to fit in the space between the mounting member 15 and the main body part 16.

このとき、端子台35は、接続面64の中央が取付部材15の取付ピッチL1の位置よりも外側に位置するように本体部16に配置され、すなわち、電線12が挿通される取付部材15の配線孔24から端子台35をできるだけ離していることにより、端子台35に接続された電線12が取付部材15と本体部16との間に収まるように容易に引き回すことができ、施工性がよい。 At this time, the terminal block 35 is arranged in the main body portion 16 so that the center of the connection surface 64 is located outside the position of the mounting pitch L1 of the mounting member 15, that is, the mounting member 15 through which the electric wire 12 is inserted. By separating the terminal block 35 from the wiring hole 24 as much as possible, the electric wire 12 connected to the terminal block 35 can be easily routed so as to fit between the mounting member 15 and the main body 16, and the workability is good. ..

そして、例えば各ねじ42のねじ部42bが取付部材15の各本体取付部22の溝部28の上縁に当たるまで本体部16を取付部材15に対して押し上げた状態で、各ねじ42を締め付け操作し、各ねじ42の頭部42aと各アーム部39，40との間で取付部材15の各本体取付部22を挟み込んで保持し、本体部16を取付部材15に固定する。 Then, for example, in a state in which the main body portion 16 is pushed up with respect to the mounting member 15 until the screw portion 42b of each screw 42 hits the upper edge of the groove portion 28 of each main body mounting portion 22 of the mounting member 15, tighten each screw 42. The main body mounting portion 22 of the mounting member 15 is sandwiched and held between the head portion 42a of each screw 42 and each arm portion 39, 40, and the main body portion 16 is fixed to the mounting member 15.

このように、本体部16の取り付けは、各ねじ42を各アーム部39，40に螺着した状態で本体部16を取付部材15に組み付け、各ねじ42を締め付ければよいため、施工性がよい。 In this way, the main body 16 can be attached by assembling the main body 16 to the attachment member 15 in a state where each screw 42 is screwed to each arm 39, 40 and tightening each screw 42. Good.

また、施工中において、ねじ42の締め付けが弱かったり、締め付けたねじ42に手などが当たってねじ42が緩むなどした場合、本体部16が自重や電線12の弾性で取付部材15に対して下降するおそれがある。仮に、本体部16が取付部材15に対して下降したとしても、ねじ42の頭部42aが取付部材15の引掛り部29に引っ掛かり、本体部16の脱落が防止される。なお、施工後においても、本体部16の脱落が防止される。 Further, during the construction, if the tightening of the screw 42 is weak, or if the screw 42 is loosened by hitting the tightened screw 42 with a hand or the like, the main body part 16 descends with respect to the mounting member 15 due to its own weight or elasticity of the electric wire 12. May occur. Even if the main body portion 16 descends with respect to the mounting member 15, the head portion 42a of the screw 42 is caught by the hooking portion 29 of the mounting member 15, and the main body portion 16 is prevented from falling off. Even after the construction, the main body 16 is prevented from falling off.

したがって、取付部材15の引掛り部29は、溝部28にねじ部42bが進入したねじ42の頭部42aが当接可能でかつ当接により取付方向ａに対して反対方向に移動するのを規制する。すなわち、取付部材15の引掛り部29は、ねじ42が本体部16に対して所定の螺着位置よりも緩められた状態で頭部42aが取付方向ａに通過可能とするとともに、ねじ42が所定の螺着位置よりも締め付けられた状態で頭部42aの取付方向ａに対して反対側が当接可能とする。 Therefore, the hook portion 29 of the mounting member 15 can prevent the head portion 42a of the screw 42 into which the screw portion 42b has entered the groove portion 28 from abutting and prevent the head portion 42a from moving in the opposite direction to the mounting direction a due to the abutment. To do. That is, the hooking portion 29 of the mounting member 15 allows the head portion 42a to pass in the mounting direction a while the screw 42 is loosened from the predetermined screwing position with respect to the main body portion 16, and the screw 42 The side opposite to the mounting direction a of the head portion 42a can be brought into contact with the head portion 42a in a state in which the head portion 42a is tightened from a predetermined screwing position.

また、本体部16を取付部材15に取り付けた状態において、端子台35の電線挿入孔66の軸方向前方には、放熱板32および本体取付部22が配置されず、開放されている。そのため、本体部16を取付部材15に取り付けた後に端子台35に接続された電線12の配置の微調整などがやりやすい。 Further, in a state in which the main body portion 16 is attached to the attachment member 15, the heat dissipation plate 32 and the main body attachment portion 22 are not arranged in front of the wire insertion hole 66 of the terminal block 35 in the axial direction and are open. Therefore, it is easy to finely adjust the arrangement of the electric wires 12 connected to the terminal block 35 after attaching the main body 16 to the attaching member 15.

続いて、本体部16を覆うようにカバー17を下方から被せ、ねじ72でカバー17を取付部材15のカバー取付部23に取り付ける。これにより、照明装置10の設置が完了する。 Subsequently, the cover 17 is covered from below so as to cover the main body portion 16, and the cover 17 is attached to the cover attachment portion 23 of the attachment member 15 with the screw 72. This completes the installation of the lighting device 10.

そして、予備電源装置からの外部電源が電線12を通じて照明装置10の電源部34に供給されると、電源部34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45に供給する。点灯電源が供給された発光モジュール45が点灯し、その光がレンズ47を通じて照明空間に照射される。 Then, when the external power source from the standby power source device is supplied to the power source unit 34 of the lighting device 10 through the electric wire 12, the power source unit 34 converts the external power source into a predetermined lighting power source and supplies it to the light emitting module 45. The light emitting module 45 to which the lighting power is supplied is turned on, and the light is applied to the illumination space through the lens 47.

点灯時に発光モジュール45が発生する熱は、放熱板32に伝達され、さらに、放熱板32から取付部材15およびカバー17に伝達され、これらから空気中に放熱される。また、被設置面11とカバー17との間の隙間73が設けられているため、カバー17の内外での通気が効率的に可能となっており、放熱板32で暖められたカバー17内の空気が効率よく排気され、放熱性能を確保することができる。 The heat generated by the light emitting module 45 at the time of lighting is transferred to the heat dissipation plate 32, further transferred from the heat dissipation plate 32 to the mounting member 15 and the cover 17, and then radiated into the air. Further, since the gap 73 between the installation surface 11 and the cover 17 is provided, it is possible to efficiently ventilate the inside and outside of the cover 17, and the inside of the cover 17 heated by the heat dissipation plate 32 Air is efficiently exhausted, and heat dissipation performance can be secured.

以上のように、本実施形態の照明装置10では、施工時において、ねじ42を本体部16に設けた状態で本体部16を取付部材15に組み付けることが可能で、施工性を向上でき、しかも、取付部材15の引掛り部29は、溝部28に進入したねじ42が取付方向ａに対して反対方向に移動するのを規制することにより、本体部16が取付部材15から脱落するのを防止できる。 As described above, in the lighting device 10 of the present embodiment, at the time of construction, the main body portion 16 can be assembled to the mounting member 15 with the screws 42 provided on the main body portion 16, and the construction efficiency can be improved, and The hook portion 29 of the mounting member 15 prevents the screw 42 that has entered the groove portion 28 from moving in the opposite direction to the mounting direction a, thereby preventing the main body portion 16 from falling off the mounting member 15. it can.

すなわち、本実施形態の照明装置10では、施工時において、ねじ42を本体部16に螺着した状態で本体部16を取付部材15に組み付けることが可能で、施工性を向上でき、しかも、取付部材15の引掛り部29は、溝部28にねじ部42bが進入したねじ42の頭部42aが当接可能でかつ当接により取付方向ａに対して反対方向に移動するのを規制することにより、本体部16が取付部材15から脱落するのを防止できる。 That is, in the lighting device 10 of the present embodiment, at the time of construction, the main body portion 16 can be assembled to the mounting member 15 in a state where the screw 42 is screwed to the main body portion 16, the construction workability can be improved, and the mounting The hook portion 29 of the member 15 restricts the head portion 42a of the screw 42 into which the screw portion 42b has entered the groove portion 28, and the movement of the head portion 42a in the opposite direction to the mounting direction a due to the contact. The main body part 16 can be prevented from falling off the mounting member 15.

さらに、引掛り部29は、ねじ42が本体部16に対して所定の螺着位置よりも緩められた状態で頭部42aが取付方向ａに通過可能とするとともに、ねじ42が所定の螺着位置よりも締め付けられた状態で頭部42aの取付方向ａに対して反対側が当接可能とするため、溝部28にねじ部42bが進入したねじ42の頭部42aが当接可能でかつ当接により取付方向ａに対して反対方向に移動するのを規制することができる。 Further, the hook portion 29 allows the head portion 42a to pass in the mounting direction a while the screw 42 is loosened from the predetermined screwing position with respect to the main body portion 16, and the screw 42 is screwed in the predetermined screwing position. Since the opposite side with respect to the mounting direction a of the head 42a is capable of contacting in a state of being tightened from the position, the head 42a of the screw 42 in which the screw portion 42b has entered the groove 28 can contact and contact. Thus, the movement in the opposite direction to the mounting direction a can be restricted.

さらに、引掛り部29は、一対の本体取付部22の溝部28の片側でかつ溝部28を介して対称位置に設けられているため、一対のねじ42のどちらかが引掛り部29に引っ掛かり、本体部16が取付部材15から脱落するのを確実に防止でき、しかも、溝部28の両側に設ける場合に比べて部品コストを低減できる。 Further, since the hook portion 29 is provided on one side of the groove portion 28 of the pair of main body mounting portions 22 and at a symmetrical position via the groove portion 28, one of the pair of screws 42 is caught by the hook portion 29, It is possible to reliably prevent the main body part 16 from falling off the mounting member 15, and it is possible to reduce the cost of parts as compared with the case where the main body part 16 is provided on both sides of the groove part 28.

また、引掛り部29は、取付部材15に一体に形成されているため、構造が簡単で部品点数を少なくできる。 Further, since the hook portion 29 is formed integrally with the mounting member 15, the structure is simple and the number of parts can be reduced.

なお、引掛り部29は、本体取付部22に対して略Ｌ字状に折曲して突出させたり、本体取付部22からダボ状に突出させてもよい。あるいは、引掛り部29は、例えば板ばねなどの別部品で構成してもよい。 The hook 29 may be bent in a substantially L shape with respect to the main body mounting portion 22 so as to project, or may be projected from the main body mounting portion 22 in a dowel shape. Alternatively, the hooking portion 29 may be configured by another component such as a leaf spring.

また、本実施形態の照明装置10では、接続面64の中央が取付部材15の取付ピッチL1の位置よりも外側に位置するように、端子台35が本体部16に配置されることにより、照明装置10の小形化によって取付部材15と本体部16との間のスペースが小さくても、取付部材15の配線孔24から本体部16に引き込まれた電線12が端子台35の接続面64の電線挿入孔66に挿入されるように、取付部材15と本体部16との間での電線12の引き回しが容易に行え、施工性がよく、小形化に対応できる。 Further, in the lighting device 10 of the present embodiment, by arranging the terminal block 35 in the main body 16 so that the center of the connection surface 64 is located outside the position of the mounting pitch L1 of the mounting member 15, Even if the space between the mounting member 15 and the main body 16 is small due to the downsizing of the device 10, the electric wire 12 drawn into the main body 16 from the wiring hole 24 of the mounting member 15 is the electric wire of the connection surface 64 of the terminal block 35. The electric wire 12 can be easily routed between the mounting member 15 and the main body portion 16 so that the electric wire 12 is inserted into the insertion hole 66, the workability is good, and the size can be reduced.

さらに、端子台35は、端子台本体63の一部が取付部材15の取付ピッチL1の位置よりも内側に位置するように本体部16に配置されていることにより、電線12の引き回しを容易としながら、照明装置10を小形化できる。 Further, the terminal block 35 is arranged in the main body 16 such that a part of the terminal block main body 63 is located inside the position of the mounting pitch L1 of the mounting member 15, thereby facilitating the routing of the electric wire 12. However, the lighting device 10 can be downsized.

さらに、取付部材15の取付板部21とこの取付板部21に対向する端子台35の面との対向方向の離間距離L3が、その対向方向に沿った端子台35の長さL4よりも小さい関係にあることにより、取付部材15と本体部16との間での電線12の引き回しが可能な範囲内で、取付板部21と本体部16とを近付け、照明装置10を小形化（薄形化）できる。しかも、離間距離L3は１４ｍｍ以下であることにより、照明装置10を小形化（薄形化）できる。 Further, the distance L3 in the facing direction between the mounting plate portion 21 of the mounting member 15 and the surface of the terminal block 35 facing the mounting plate portion 21 is smaller than the length L4 of the terminal block 35 along the facing direction. Due to the relationship, the mounting plate portion 21 and the main body portion 16 are brought close to each other within a range where the electric wire 12 can be routed between the mounting member 15 and the main body portion 16, and the lighting device 10 is downsized (thin type). You can Moreover, since the separation distance L3 is 14 mm or less, the illumination device 10 can be downsized (thinned).

さらに、取付部材15の取付板部21とこの取付板部21に対向する端子台35の面に対して反対側の面との間の距離L5は、中心軸18と端子台35の接続面64の中央部ｓとの間の距離L2よりも小さい関係にあることにより、取付部材15と本体部16との間での電線12の引き回しが可能な範囲内で、取付板部21と本体部16とを近付け、照明装置10を小形化（薄形化）できる。 Further, the distance L5 between the mounting plate portion 21 of the mounting member 15 and the surface opposite to the surface of the terminal block 35 facing the mounting plate portion 21 is determined by the connecting surface 64 of the central shaft 18 and the terminal block 35. Since the distance L2 is smaller than the distance L2 between the central portion s of the mounting plate portion 21 and the main body portion 16, the electric wire 12 can be routed between the mounting member 15 and the main body portion 16. And the lighting device 10 can be made smaller (thinner) by bringing them closer to each other.

なお、本実施形態のように電線12に曲がりにくい耐火ケーブルを用いる構成では、取付部材15と本体部16との間での電線12の引き回しを考慮すると、取付部材15の配線孔24および取付孔25，26が設けられる面である取付板部21の下面とこの面に対向する端子台35の面である上面との間の距離は１４ｍｍ程度が好ましい。 In the configuration using the refractory cable that is hard to bend in the electric wire 12 as in the present embodiment, considering the wiring of the electric wire 12 between the mounting member 15 and the main body portion 16, the wiring hole 24 and the mounting hole of the mounting member 15 are considered. It is preferable that the distance between the lower surface of the mounting plate portion 21, which is the surface on which 25 and 26 are provided, and the upper surface, which is the surface of the terminal block 35, facing this surface is about 14 mm.

また、端子台35の電線挿入孔66の軸方向前方が取付部材15の配線孔24の方向に対向するように、電源部34の端部に配置してもよい。この場合にも、端子台35の接続面64の中央が取付部材15の取付ピッチの位置よりも外側に位置すればよい。 Further, the terminal block 35 may be arranged at the end of the power supply section 34 such that the axial front side of the wire insertion hole 66 faces the wiring hole 24 of the mounting member 15. Also in this case, the center of the connection surface 64 of the terminal block 35 may be located outside the position of the mounting pitch of the mounting members 15.

なお、固定部材としては、ねじ42に限らず、径大な頭部を有するピンや、板ばねなどを用いてもよく、これらの場合にもねじ42と同様の作用効果を得られる。 The fixing member is not limited to the screw 42, but a pin having a large-diameter head, a leaf spring, or the like may be used, and in these cases, the same effect as the screw 42 can be obtained.

なお、本実施形態の照明装置10の構成は、非常用照明装置に限らず、一般照明用の照明装置にも適用できる。 The configuration of the illumination device 10 according to the present embodiment is not limited to the emergency illumination device and can be applied to the illumination device for general illumination.
