Description

照明用の電源ユニット及び照明装置Power unit for lighting and lighting device
　本発明は、照明用の電源ユニット及び照明装置に関するものである。 The present invention relates to a power supply unit for lighting and a lighting device.
　天井に埋め込んで使用されるダウンライト型の照明装置において、ＬＥＤを光源として用いたものがある（例えば、特許文献１参照）。 There is a downlight type illuminating device used by being embedded in a ceiling using an LED as a light source (see, for example, Patent Document 1).
　器具に取り付けて使用される電球型の照明装置においても、ＬＥＤを光源として用いたものがある（例えば、特許文献２参照）。 Some bulb-type lighting devices that are used by being attached to an appliance also use LEDs as light sources (see, for example, Patent Document 2).

　従来のダウンライト型の照明装置では、ヒートシンク部材が本体部と一体的に又は本体部の一部としてアルミニウム合金等から形成されている。そのため、照明装置の用途に合わせてヒートシンク部材の仕様を変更する場合には、本体部の仕様も変更しなければならず、多様なニーズに対応しにくいという課題がある。 In the conventional downlight type lighting device, the heat sink member is formed of an aluminum alloy or the like integrally with the main body or as a part of the main body. For this reason, when the specification of the heat sink member is changed in accordance with the use of the lighting device, the specification of the main body must also be changed, and there is a problem that it is difficult to meet various needs.
　一方、従来の電球型の照明装置では、冷却フィン部が筒状本体の外周面に取り付けられている。そのため、筒状本体の仕様を変更することなく、照明装置の用途に合わせて冷却フィン部の仕様のみを変更するといったことが可能である。しかし、従来の電球型の照明装置では、筒状本体の一端の外周部に支持部材がカシメ止めされ、この支持部材にＬＥＤモジュールが支持台を介して固定されている。そのため、ＬＥＤに生じた熱が支持台から支持部材、筒状本体、冷却フィン部へと伝わる過程で、筒状本体と支持部材とのカシメ止め箇所に生じる熱抵抗によって伝熱量が低減してしまうという課題がある。 On the other hand, in the conventional light bulb-type lighting device, the cooling fin portion is attached to the outer peripheral surface of the cylindrical main body. Therefore, it is possible to change only the specification of the cooling fin portion according to the use of the lighting device without changing the specification of the cylindrical main body. However, in a conventional light bulb-type lighting device, a support member is crimped to the outer peripheral portion of one end of the cylindrical main body, and the LED module is fixed to the support member via a support base. Therefore, in the process in which the heat generated in the LED is transferred from the support base to the support member, the cylindrical main body, and the cooling fin portion, the heat transfer amount is reduced by the thermal resistance generated at the crimping stop portion between the cylindrical main body and the support member. There is a problem.
　また、従来のダウンライト型及び電球型の照明装置のいずれにおいても、ＬＥＤを点灯させる電源基板が本体部又は筒状本体に直接収容されている。そのため、電源基板の設置及び配線の作業ができるように、本体部又は筒状本体の中に余分なスペースを確保しておかなければならず、照明装置を小型化しにくいという課題がある。 Also, in both the conventional downlight type and light bulb type lighting devices, the power supply substrate for lighting the LED is directly accommodated in the main body or the cylindrical main body. Therefore, an extra space must be secured in the main body or the cylindrical main body so that the power supply board can be installed and wired, and there is a problem that it is difficult to reduce the size of the lighting device.
　本発明は、照明装置の放熱性の向上、或いは、照明装置の小型化を目的とする。 The present invention aims to improve the heat dissipation of the lighting device or to reduce the size of the lighting device.
　本発明の一の態様に係る照明用の電源ユニットは、
　発光素子を含む光源回路が配置された光源ユニットに点灯電力を供給する照明用の電源ユニットであって、
　点灯回路が配置された電源基板と、
　前記電源基板を収容する第１収容部と、隔壁により前記第１収容部と隔てられた第２収容部とを有する収容体と、
　筒状の周壁部と、前記周壁部の一端を塞ぐ底壁部とを有し、前記収容体が内側に収納され、前記光源ユニットが外側から前記底壁部に連結可能な筐体と、
　前記第１収容部から前記隔壁を越えて前記第２収容部に入り、前記第２収容部から前記第２収容部の底壁に設けられた貫通孔と前記底壁部に設けられた貫通孔とを通って前記収容体と前記筐体との外側に出て、前記点灯回路と前記光源回路とを電気接続することで、前記点灯回路から前記光源回路への点灯電力の出力経路となる出力電線とを備える。 A power supply unit for illumination according to one aspect of the present invention is
A power supply unit for illumination that supplies lighting power to a light source unit in which a light source circuit including a light emitting element is disposed,
A power supply board on which a lighting circuit is arranged;
A housing having a first housing portion for housing the power supply substrate, and a second housing portion separated from the first housing portion by a partition;
A casing having a cylindrical peripheral wall portion and a bottom wall portion that closes one end of the peripheral wall portion, the housing is housed inside, and the light source unit can be connected to the bottom wall portion from the outside;
A through hole provided in the bottom wall of the second storage part from the second storage part and a through hole provided in the bottom wall part from the first storage part to the second storage part across the partition And the outside of the housing and the casing through the electrical connection, the electrical connection between the lighting circuit and the light source circuit, the output serving as the output path of the lighting power from the lighting circuit to the light source circuit With electric wires.
　本発明では、電源ユニットの筐体の内側に収納される収容体に、電源基板が収容されるスペースと、出力電線が収容されるスペースとが別々に確保されているため、この電源ユニットを照明装置に適用することで、照明装置の小型化が可能となる。 In the present invention, since the space for accommodating the power supply board and the space for accommodating the output electric wires are separately secured in the housing accommodated inside the casing of the power supply unit, the power supply unit is illuminated. By applying to the device, the lighting device can be downsized.

The configuration of the apparatus according to the present embodiment and the effects of the present embodiment will be described in order.
　＊＊＊構成の説明＊＊＊
　図１及び図２及び図３を参照して、本実施の形態に係る装置である照明装置１００の構成を説明する。 *** Explanation of configuration ***
With reference to FIG.1, FIG2 and FIG.3, the structure of the illuminating device 100 which is an apparatus which concerns on this Embodiment is demonstrated.
　照明装置１００は、光源ユニット２００と、光源ユニット２００に点灯電力を供給する照明用の電源ユニット３００とを備える。 The illumination device 100 includes a light source unit 200 and an illumination power supply unit 300 that supplies lighting power to the light source unit 200.
　光源ユニット２００は、光源基板２１０と、板状部材２２０と、絶縁シート２３０と、反射板２４０と、拡散板２５０とを有する。 The light source unit 200 includes a light source substrate 210, a plate-like member 220, an insulating sheet 230, a reflection plate 240, and a diffusion plate 250.
　光源基板２１０には、ＬＥＤである発光素子２１１が実装される。即ち、光源基板２１０には、発光素子２１１を含む光源回路が配置される。発光素子２１１の個数は、任意の個数でよいが、本実施の形態では２６個である。なお、発光素子２１１は、有機ＥＬ又はレーザといったＬＥＤ以外の固体発光素子であってもよい。また、発光素子２１１は、光源基板２１０に実装されていなくてもよく、発光素子２１１を含む光源回路が光源ユニット２００に配置されていればよい。 A light emitting element 211 that is an LED is mounted on the light source substrate 210. That is, a light source circuit including the light emitting element 211 is disposed on the light source substrate 210. The number of the light emitting elements 211 may be an arbitrary number, but is 26 in this embodiment. The light emitting element 211 may be a solid light emitting element other than an LED such as an organic EL or a laser. Further, the light emitting element 211 may not be mounted on the light source substrate 210, and a light source circuit including the light emitting element 211 may be disposed in the light source unit 200.
　板状部材２２０は、それぞれオモテ面とウラ面となる２つの板面２２１，２２２を有する。一方の板面２２１には、光源基板２１０が固定される。即ち、一方の板面２２１には、発光素子２１１を含む光源回路が配置される。他方の板面２２２は、電源ユニット３００に連結される。 The plate-like member 220 has two plate surfaces 221 and 222 that become a front surface and a back surface, respectively. The light source substrate 210 is fixed to one plate surface 221. That is, a light source circuit including the light emitting element 211 is disposed on one plate surface 221. The other plate surface 222 is connected to the power supply unit 300.
　本実施の形態において、板状部材２２０の一方の板面２２１には、絶縁シート２３０、光源基板２１０、反射板２４０、拡散板２５０が順番に重ねて取り付けられる。板状部材２２０、絶縁シート２３０、反射板２４０、拡散板２５０には、対応する複数の位置にネジ穴が設けられる。ネジが拡散板２５０、反射板２４０、絶縁シート２３０のそれぞれのネジ穴を順番に貫通して板状部材２２０のネジ穴に挿入されて締められることで、絶縁シート２３０、反射板２４０、拡散板２５０が板状部材２２０に固定される。光源基板２１０は、絶縁シート２３０と反射板２４０との間に挟み込まれることで固定される。なお、光源基板２１０にもネジ穴が設けられてよい。その場合、ネジが拡散板２５０、反射板２４０、光源基板２１０、絶縁シート２３０のそれぞれのネジ穴を順番に貫通して板状部材２２０のネジ穴に挿入される。 In this embodiment, the insulating sheet 230, the light source substrate 210, the reflection plate 240, and the diffusion plate 250 are attached to one plate surface 221 of the plate-like member 220 so as to overlap in order. The plate-like member 220, the insulating sheet 230, the reflection plate 240, and the diffusion plate 250 are provided with screw holes at a plurality of corresponding positions. The screws penetrate the respective screw holes of the diffusion plate 250, the reflection plate 240, and the insulation sheet 230 in order and are inserted into the screw holes of the plate-like member 220 and tightened, so that the insulation sheet 230, the reflection plate 240, and the diffusion plate are tightened. 250 is fixed to the plate-like member 220. The light source substrate 210 is fixed by being sandwiched between the insulating sheet 230 and the reflection plate 240. The light source substrate 210 may also be provided with a screw hole. In that case, screws are inserted into the screw holes of the plate-like member 220 through the screw holes of the diffusion plate 250, the reflection plate 240, the light source substrate 210, and the insulating sheet 230 in order.
　板状部材２２０は、熱伝導性材料により形成される。本実施の形態では、板状部材２２０は、金属材料により一体成形される。 The plate-like member 220 is made of a heat conductive material. In the present embodiment, the plate-like member 220 is integrally formed of a metal material.
　絶縁シート２３０は、板状部材２２０と光源基板２１０との間に挟み込まれ、光源基板２１０を板状部材２２０から電気的に絶縁する。 The insulating sheet 230 is sandwiched between the plate-like member 220 and the light source substrate 210 and electrically insulates the light source substrate 210 from the plate-like member 220.
　反射板２４０には、発光素子２１１を露出させるための円形の開口部２４１が設けられる。反射板２４０は、発光素子２１１からの光を開口部２４１の内周面で反射する。 The reflection plate 240 is provided with a circular opening 241 for exposing the light emitting element 211. The reflector 240 reflects the light from the light emitting element 211 on the inner peripheral surface of the opening 241.
　拡散板２５０は、透光性材料により形成される。拡散板２５０は、発光素子２１１から直接放射された光と反射板２４０で反射された光とを拡散しながら透過させる。 The diffusion plate 250 is made of a translucent material. The diffusing plate 250 transmits the light directly emitted from the light emitting element 211 and the light reflected by the reflecting plate 240 while diffusing.
　電源ユニット３００は、電源基板３１０と、出力電線３２０と、筐体３３０と、蓋体３４０と、端子台３５０と、入力電線３６０と、収容体３７０と、筒状のヒートシンク３９０とを備える。 The power supply unit 300 includes a power supply substrate 310, an output electric wire 320, a housing 330, a lid 340, a terminal block 350, an input electric wire 360, a container 370, and a cylindrical heat sink 390.
　電源基板３１０には、点灯回路３１１が配置される。 A lighting circuit 311 is disposed on the power supply substrate 310.
　出力電線３２０は、電源基板３１０と光源基板２１０とを電気接続することで、点灯回路３１１から発光素子２１１を含む光源回路への点灯電力の出力経路となる。即ち、出力電線３２０は、電源基板３１０に配置された点灯回路３１１と光源基板２１０に配置された光源回路とを電気接続することで、点灯回路３１１から光源回路への点灯電力の出力経路となる。 The output electric wire 320 serves as an output path of lighting power from the lighting circuit 311 to the light source circuit including the light emitting element 211 by electrically connecting the power supply substrate 310 and the light source substrate 210. That is, the output electric wire 320 becomes an output path of lighting power from the lighting circuit 311 to the light source circuit by electrically connecting the lighting circuit 311 arranged on the power supply board 310 and the light source circuit arranged on the light source board 210. .
　筐体３３０は、円筒状の周壁部３３１と、底壁部３３２とを有する。底壁部３３２は、周壁部３３１と一体成形される。底壁部３３２は、周壁部３３１の一端を塞ぐ。筐体３３０の内側には、電源基板３１０が収容される収容空間が形成される。筐体３３０は、光源ユニット２００を外側から底壁部３３２に取り付けることができるように構成されている。底壁部３３２には、出力電線３２０が筐体３３０の内側から筐体３３０の外側に挿通される貫通孔３３３が設けられる。本実施の形態では、底壁部３３２には、光源ユニット２００が筐体３３０の外側から連結される。具体的には、底壁部３３２には、板状部材２２０の他方の板面２２２が連結される。 The housing 330 has a cylindrical peripheral wall portion 331 and a bottom wall portion 332. The bottom wall portion 332 is integrally formed with the peripheral wall portion 331. The bottom wall portion 332 closes one end of the peripheral wall portion 331. A housing space for housing the power supply substrate 310 is formed inside the housing 330. The housing 330 is configured such that the light source unit 200 can be attached to the bottom wall portion 332 from the outside. The bottom wall portion 332 is provided with a through hole 333 through which the output electric wire 320 is inserted from the inside of the housing 330 to the outside of the housing 330. In the present embodiment, light source unit 200 is connected to bottom wall portion 332 from the outside of housing 330. Specifically, the other plate surface 222 of the plate-like member 220 is connected to the bottom wall portion 332.
　筐体３３０は、上記のように構成されているため、発光素子２１１の点灯中に光源ユニット２００から発生する熱を底壁部３３２と光源ユニット２００との連結箇所から底壁部３３２を介して周壁部３３１に伝導させて放熱する。本実施の形態では、周壁部３３１と底壁部３３２とが一体成形されているため、周壁部３３１と底壁部３３２との間に熱抵抗が生じにくい。よって、ＬＥＤに生じた熱を光源ユニット２００から底壁部３３２、周壁部３３１へと効率よく伝えることができる。 Since the housing 330 is configured as described above, heat generated from the light source unit 200 during the lighting of the light emitting element 211 is transmitted from the connection portion between the bottom wall portion 332 and the light source unit 200 via the bottom wall portion 332. It is conducted to the peripheral wall portion 331 to dissipate heat. In the present embodiment, since the peripheral wall portion 331 and the bottom wall portion 332 are integrally formed, thermal resistance is unlikely to occur between the peripheral wall portion 331 and the bottom wall portion 332. Therefore, the heat generated in the LED can be efficiently transmitted from the light source unit 200 to the bottom wall portion 332 and the peripheral wall portion 331.
　蓋体３４０は、周壁部３３１の他端を塞ぐ。蓋体３４０は、熱伝導性材料により形成される。本実施の形態では、蓋体３４０は、金属材料により一体成形される。 The lid body 340 closes the other end of the peripheral wall portion 331. The lid 340 is made of a heat conductive material. In the present embodiment, lid body 340 is integrally formed of a metal material.
　端子台３５０は、図示していない商用電源等の外部電源に接続される。端子台３５０は、筐体３３０の外側から蓋体３４０に固定される。 The terminal block 350 is connected to an external power source such as a commercial power source (not shown). The terminal block 350 is fixed to the lid 340 from the outside of the housing 330.
　入力電線３６０は、電源基板３１０と端子台３５０とを電気接続することで、外部電源から点灯回路３１１への点灯電力の入力経路となる。 The input electric wire 360 serves as an input path of lighting power from the external power source to the lighting circuit 311 by electrically connecting the power supply substrate 310 and the terminal block 350.
　筐体３３０は、前述した周壁部３３１と底壁部３３２とのほかに、フランジ部３３４を有する。フランジ部３３４は、底壁部３３２と同じように、周壁部３３１と一体成形される。フランジ部３３４は、周壁部３３１の他端から周壁部３３１の中心軸方向に対して垂直に突出する。即ち、フランジ部３３４は、周壁部３３１の他端から周壁部３３１の半径方向に突出する。周壁部３３１には、入力電線３６０を筐体３３０の外側から筐体３３０の内側に通す切り欠き３３５が設けられる。フランジ部３３４には、蓋体３４０が連結される。なお、入力電線３６０を通すために、切り欠き３３５の代わりに、貫通孔が周壁部３３１に設けられてもよい。フランジ部３３４の位置及び個数は、任意の位置及び個数でよいが、本実施の形態では周壁部３３１の半径方向に沿って対向する２つの位置にフランジ部３３４が設けられている。よって、フランジ部３３４の個数は２個である。 The housing 330 includes a flange portion 334 in addition to the peripheral wall portion 331 and the bottom wall portion 332 described above. The flange portion 334 is integrally formed with the peripheral wall portion 331 in the same manner as the bottom wall portion 332. The flange portion 334 protrudes perpendicularly from the other end of the peripheral wall portion 331 with respect to the central axis direction of the peripheral wall portion 331. That is, the flange portion 334 protrudes from the other end of the peripheral wall portion 331 in the radial direction of the peripheral wall portion 331. The peripheral wall portion 331 is provided with a notch 335 for passing the input electric wire 360 from the outside of the housing 330 to the inside of the housing 330. A lid 340 is connected to the flange portion 334. In order to pass the input electric wire 360, a through hole may be provided in the peripheral wall portion 331 instead of the notch 335. The position and the number of the flange portions 334 may be arbitrary positions and numbers, but in the present embodiment, the flange portions 334 are provided at two positions facing each other along the radial direction of the peripheral wall portion 331. Therefore, the number of flange portions 334 is two.
　筐体３３０は、上記のように構成されているため、発光素子２１１の点灯中に光源ユニット２００から発生する熱を底壁部３３２と光源ユニット２００との連結箇所から底壁部３３２と周壁部３３１とフランジ部３３４とを介してフランジ部３３４と蓋体３４０との連結箇所まで伝導させて放熱する。本実施の形態では、周壁部３３１とフランジ部３３４とが一体成形されているため、周壁部３３１とフランジ部３３４との間に熱抵抗が生じにくい。よって、ＬＥＤに生じた熱を光源ユニット２００から底壁部３３２、周壁部３３１、フランジ部３３４、蓋体３４０へと効率よく伝えることができる。 Since the housing 330 is configured as described above, heat generated from the light source unit 200 during the lighting of the light emitting element 211 is transmitted from the connecting portion between the bottom wall portion 332 and the light source unit 200 to the bottom wall portion 332 and the peripheral wall portion. Heat is dissipated through conduction to the connecting portion between the flange portion 334 and the lid 340 via the 331 and the flange portion 334. In the present embodiment, since the peripheral wall portion 331 and the flange portion 334 are integrally formed, thermal resistance hardly occurs between the peripheral wall portion 331 and the flange portion 334. Therefore, the heat generated in the LED can be efficiently transmitted from the light source unit 200 to the bottom wall portion 332, the peripheral wall portion 331, the flange portion 334, and the lid 340.
　筐体３３０は、熱伝導性材料により形成される。本実施の形態では、筐体３３０は、金属材料により一体成形される。具体的には、筐体３３０は、１枚の金属板を絞り加工してコップ状に成形される。なお、筐体３３０は、ダイキャスト加工等、絞り加工以外の方法で製造されてもよい。 The housing 330 is formed of a heat conductive material. In the present embodiment, the housing 330 is integrally formed of a metal material. Specifically, the housing 330 is formed into a cup shape by drawing a single metal plate. Note that the housing 330 may be manufactured by a method other than drawing, such as die casting.
　本実施の形態の変形例として、底壁部３３２と周壁部３３１又は蓋体３４０とのそれぞれに通気孔が設けられてもよい。その場合、通気孔の一方から他方までつながる通気経路が筐体３３０の内側に形成される。これにより、対流が発生し、筐体３３０の放熱性が向上する。なお、底壁部３３２に設けられた貫通孔３３３が通気孔を兼ねてもよい。また、周壁部３３１に設けられた切り欠き３３５が通気孔を兼ねてもよい。 As a modification of the present embodiment, a vent hole may be provided in each of the bottom wall portion 332 and the peripheral wall portion 331 or the lid body 340. In that case, a ventilation path connected from one of the ventilation holes to the other is formed inside the housing 330. Thereby, a convection arises and the heat dissipation of the housing | casing 330 improves. The through hole 333 provided in the bottom wall portion 332 may also serve as a vent hole. Further, the notch 335 provided in the peripheral wall portion 331 may also serve as a vent hole.
　収容体３７０は、筐体３３０の内側に収納される。収容体３７０は、電源基板３１０を収容する。このように、本実施の形態では、電源基板３１０が、筐体３３０の内側に形成された収容空間に直接収容されるのではなく、収容体３７０を介して収容される。そのため、筐体３３０の中に収容体３７０を設置するスペースがあればよく、余分なスペースを確保しておく必要はない。 The container 370 is housed inside the housing 330. The container 370 houses the power supply substrate 310. As described above, in the present embodiment, the power supply substrate 310 is not directly stored in the storage space formed inside the housing 330 but is stored via the storage body 370. Therefore, it is sufficient that there is a space for installing the container 370 in the housing 330, and it is not necessary to secure an extra space.
　収容体３７０は、絶縁性材料により形成される。本実施の形態では、収容体３７０は、樹脂材料により一体成形される。 The container 370 is made of an insulating material. In the present embodiment, container 370 is integrally formed of a resin material.
　ヒートシンク３９０は、筐体３３０の外側から周壁部３３１に固定される。そのため、本実施の形態では、筐体３３０の仕様を変更することなく、照明装置１００の用途に合わせてヒートシンク３９０の仕様のみを変更するといったことが可能である。 The heat sink 390 is fixed to the peripheral wall portion 331 from the outside of the housing 330. Therefore, in this embodiment, it is possible to change only the specification of the heat sink 390 in accordance with the application of the lighting device 100 without changing the specification of the housing 330.
　ヒートシンク３９０は、周壁部３３１が圧入されることで周壁部３３１に固定されてもよいが、本実施の形態では周壁部３３１に連結されることで周壁部３３１に固定される。具体的には、ヒートシンク３９０は、周壁部３３１にカシメ止めされる。そのため、筐体３３０は、発光素子２１１の点灯中に光源ユニット２００から発生する熱を底壁部３３２と光源ユニット２００との連結箇所から底壁部３３２と周壁部３３１とを介して周壁部３３１とヒートシンク３９０との連結箇所まで伝導させて放熱する。本実施の形態では、周壁部３３１とヒートシンク３９０との連結箇所を多くすることで、ＬＥＤに生じた熱を光源ユニット２００から底壁部３３２、周壁部３３１、ヒートシンク３９０へと効率よく伝えることができる。 The heat sink 390 may be fixed to the peripheral wall portion 331 by press-fitting the peripheral wall portion 331. However, in the present embodiment, the heat sink 390 is fixed to the peripheral wall portion 331 by being connected to the peripheral wall portion 331. Specifically, the heat sink 390 is crimped to the peripheral wall portion 331. Therefore, the housing 330 generates heat generated from the light source unit 200 during the lighting of the light emitting element 211 from the connection portion between the bottom wall portion 332 and the light source unit 200 via the bottom wall portion 332 and the peripheral wall portion 331. The heat is conducted to the connection point between the heat sink 390 and the heat sink 390. In this embodiment, by increasing the number of connection points between the peripheral wall portion 331 and the heat sink 390, heat generated in the LED can be efficiently transmitted from the light source unit 200 to the bottom wall portion 332, the peripheral wall portion 331, and the heat sink 390. it can.
　本実施の形態において、照明装置１００は、天井に埋め込んで使用されるダウンライト型の照明装置である。そのため、照明装置１００は、さらに、環状の枠４００と、複数の板バネ５００とを備える。 In this embodiment, the lighting device 100 is a downlight type lighting device that is used by being embedded in a ceiling. Therefore, the lighting device 100 further includes an annular frame 400 and a plurality of leaf springs 500.
　図４を参照して、照明装置１００の設置例を説明する。図４では、天井材６００の断面と、天井材６００に設けられた埋め込み穴６０１に嵌め込まれた照明装置１００の側面とを示している。 Referring to FIG. 4, an installation example of lighting device 100 will be described. In FIG. 4, a cross section of the ceiling material 600 and a side surface of the lighting device 100 fitted in the embedded hole 601 provided in the ceiling material 600 are shown.
　枠４００の外径Ｒ１は、埋め込み穴６０１の外径Ｒ２よりも大きい。 The outer diameter R1 of the frame 400 is larger than the outer diameter R2 of the embedding hole 601.
　板バネ５００は、枠４００を天井の埋め込み穴６０１の周囲に固定するために、枠４００の円周方向に沿って枠４００に複数取り付けられる。なお、板バネ５００の本数は、図２及び図３に示したように、本実施の形態では３本であるが、２本又は４本以上でもよい。 A plurality of leaf springs 500 are attached to the frame 400 along the circumferential direction of the frame 400 in order to fix the frame 400 around the embedding hole 601 in the ceiling. The number of leaf springs 500 is three in this embodiment as shown in FIGS. 2 and 3, but may be two or four or more.
　本実施の形態では、光源ユニット２００と、電源ユニット３００の蓋体３４０以外の部分が、埋め込み穴６０１の開孔径以下の範囲内に配置され、開孔中心に軸心が揃う形状としたので、大きく傾けることなく照明装置１００を埋め込み穴６０１に挿入することができる。 In the present embodiment, the portion other than the light source unit 200 and the lid 340 of the power supply unit 300 is disposed within the range of the opening diameter of the embedded hole 601 and the center of the opening is aligned. The lighting device 100 can be inserted into the embedding hole 601 without being greatly inclined.
　本実施の形態の変形例として、スポットライト型、フランジライト型、シーリングライト型、ブラケットライト型、ペンダントライト型といった、ダウンライト型とは異なる種類の照明装置に、本実施の形態と同じ光源ユニット２００及び電源ユニット３００が備えられてもよい。 As a modification of the present embodiment, the same light source unit as the present embodiment is used for a different type of illumination device such as a spotlight type, a flange light type, a ceiling light type, a bracket light type, and a pendant light type. 200 and the power supply unit 300 may be provided.
　以下では、電源ユニット３００の筐体３３０、ヒートシンク３９０、収容体３７０の詳細について順番に説明する。 Hereinafter, details of the casing 330, the heat sink 390, and the housing 370 of the power supply unit 300 will be described in order.
　図５及び図６を参照して、筐体３３０の詳細について説明する。 Details of the housing 330 will be described with reference to FIGS.
　筐体３３０は、発光素子２１１が配置可能な構成であり、発光素子２１１の動作熱を外部空間に伝達する放熱経路であるとともに、内部に電源基板３１０を収納して類焼防止壁として機能する。放熱経路の外に設けた筐体に電源基板を収納した構成と比較して、大幅な小型化と軽量化とを達成することができる。小型化と軽量化は、包装の簡素化、物流効率、施工性の改善、即ち、施工効率の向上に寄与する。軽量化は、落下リスクを低減させるとともに、天井材６００の強度緩和に寄与するため、コストダウンにつながる。本実施の形態の変形例として、壁に設置される照明装置に、本実施の形態と同じ光源ユニット２００及び電源ユニット３００が備えられる場合、軽量化は、壁材の強度緩和に寄与する。 The housing 330 has a configuration in which the light emitting element 211 can be arranged. The housing 330 is a heat dissipation path for transmitting the operation heat of the light emitting element 211 to the external space, and also functions as an anti-burning wall by housing the power supply substrate 310 therein. Compared with a configuration in which the power supply substrate is housed in a casing provided outside the heat dissipation path, a significant reduction in size and weight can be achieved. The reduction in size and weight contributes to the simplification of packaging, the improvement of logistics efficiency and workability, that is, the improvement of construction efficiency. The weight reduction reduces the risk of falling and contributes to the relaxation of the strength of the ceiling material 600, leading to cost reduction. As a modification of the present embodiment, when a lighting device installed on a wall includes the same light source unit 200 and power supply unit 300 as in the present embodiment, weight reduction contributes to a reduction in the strength of the wall material.
　なお、前述した蓋体３４０も、筐体３３０を塞いで類焼防止壁及び放熱経路として機能する。 Note that the above-described lid body 340 also functions as an anti-sintering prevention wall and a heat dissipation path by closing the casing 330.
　筐体３３０は、板状の不燃性材料を用いて形成される。筐体３３０は、板状の金属材料を用いてプレス成形によって有底筒状に形成される。筐体３３０は、底壁部３３２と周壁部３３１とが一体であり、一様の熱抵抗であって、即ち、熱抵抗の不連続点がなく、熱伝導性に優れている。つまり、筐体３３０は、熱的に一体の構造である。 The housing 330 is formed using a plate-like incombustible material. The housing 330 is formed into a bottomed cylindrical shape by press molding using a plate-shaped metal material. The casing 330 has a bottom wall portion 332 and a peripheral wall portion 331 that are integral with each other and have a uniform thermal resistance, that is, no thermal resistance discontinuity and excellent thermal conductivity. That is, the housing 330 has a thermally integrated structure.
　筐体３３０の開口端部には、外側に向かって張り出すフランジ部３３４が一体形成される。フランジ部３３４は、蓋体３４０をネジ止めするための取り付け片として用いられる。筐体３３０は、フランジ部３３４と周壁部３３１とが一体であり、一様の熱抵抗であって、即ち、熱抵抗の不連続点がなく、熱伝導性に優れている。つまり、筐体３３０は、熱的に一体の構造である。 A flange portion 334 that projects outward is integrally formed at the opening end of the housing 330. The flange portion 334 is used as an attachment piece for screwing the lid 340. In the housing 330, the flange portion 334 and the peripheral wall portion 331 are integrated, and have a uniform thermal resistance, that is, there is no discontinuity of the thermal resistance, and the thermal conductivity is excellent. That is, the housing 330 has a thermally integrated structure.
　筐体３３０は、周壁部３３１と底壁部３３２とフランジ部３３４とが一体に形成されたので、部品員数が少なく、優れた組み立て性と堅牢性とを備える。 Since the peripheral wall portion 331, the bottom wall portion 332, and the flange portion 334 are integrally formed, the housing 330 has a small number of parts, and has excellent assemblability and robustness.
　本実施の形態では、周壁部３３１と底壁部３３２とのつながる部分である連続部３３６の外径が底壁部３３２から周壁部３３１に向かって徐々に大きくなる。即ち、筐体３３０の縦断面において、周壁部３３１の外周面と底壁部３３２の外側の表面とが直角につながるのではなく、湾曲しながらつながっている。そのため、底壁部３３２の外側の表面付近を流れる空気が、連続部３３６の外側の表面に沿って周壁部３３１の外周面まで流れやすくなり、筐体３３０の放熱性が向上する。 In the present embodiment, the outer diameter of the continuous portion 336, which is a portion connecting the peripheral wall portion 331 and the bottom wall portion 332, gradually increases from the bottom wall portion 332 toward the peripheral wall portion 331. That is, in the longitudinal section of the housing 330, the outer peripheral surface of the peripheral wall portion 331 and the outer surface of the bottom wall portion 332 are not connected at a right angle but connected while being curved. Therefore, the air flowing in the vicinity of the outer surface of the bottom wall portion 332 easily flows along the outer surface of the continuous portion 336 to the outer peripheral surface of the peripheral wall portion 331, and the heat dissipation of the housing 330 is improved.
　また、本実施の形態では、連続部３３６の内径も底壁部３３２から周壁部３３１に向かって徐々に大きくなる。即ち、筐体３３０の縦断面において、周壁部３３１の内周面と底壁部３３２の内側の表面とが直角につながるのではなく、湾曲しながらつながっている。そのため、収容体３７０の底が筐体３３０と同じような形状になっていない限り、収容体３７０と周壁部３３１との間、或いは、収容体３７０と底壁部３３２との間に隙間が形成される。これにより、筐体３３０から収容体３７０への伝熱を抑制することができる。 In the present embodiment, the inner diameter of the continuous portion 336 also gradually increases from the bottom wall portion 332 toward the peripheral wall portion 331. That is, in the longitudinal section of the housing 330, the inner peripheral surface of the peripheral wall portion 331 and the inner surface of the bottom wall portion 332 are not connected at a right angle but connected while being curved. Therefore, unless the bottom of the container 370 has the same shape as the housing 330, a gap is formed between the container 370 and the peripheral wall 331 or between the container 370 and the bottom wall 332. Is done. Thereby, the heat transfer from the housing | casing 330 to the container 370 can be suppressed.
　前述したように、蓋体３４０と底壁部３３２とに通気用の貫通孔が設けられてもよい。その場合、筐体３３０と収容体３７０との間の隙間に空気を流入させて、発光素子２１１及び電源基板３１０の温度上昇を抑制させることができる。 As described above, a through-hole for ventilation may be provided in the lid 340 and the bottom wall portion 332. In that case, air can be allowed to flow into the gap between the housing 330 and the container 370, and temperature rises of the light emitting element 211 and the power supply substrate 310 can be suppressed.
　入力電線３６０を通す切り欠き３３５は、蓋体３４０の貫通孔に代えて通気孔を兼ねることができる。 The notch 335 through which the input electric wire 360 passes can also serve as a ventilation hole instead of the through hole of the lid 340.
　図７及び図８及び図９を参照して、ヒートシンク３９０の詳細について説明する。図７及び図８では、空気の流れを矢印で示している。 Details of the heat sink 390 will be described with reference to FIGS. 7, 8, and 9. In FIG.7 and FIG.8, the flow of air is shown by the arrow.
　発光素子２１１から発生する動作熱に応じて、筐体３３０の外周部には、ヒートシンク３９０を選択的に装着できる。 Depending on the operating heat generated from the light emitting element 211, a heat sink 390 can be selectively mounted on the outer periphery of the housing 330.
　ヒートシンク３９０は、熱伝導性材料からなる。ヒートシンク３９０は、波状に折れ曲がることでヒートシンク３９０の中心軸から離れる方向に凸の山部３９１とヒートシンク３９０の中心軸に近づく方向に凸の谷部３９２とを交互に形成しながら１周延びる金属板により形成される。即ち、ヒートシンク３９０は、折り曲げ可能な環状の板材を波状に折り曲げて筒状に加工されている。つまり、ヒートシンク３９０は、波状に折り曲げられて山部３９１と谷部３９２とが交互に形成された金属板からなり、山部３９１を外側（外方）に谷部３９２を内側（内方）にそれぞれ向けて１周回する。山部３９１の個数は、任意の個数でよいが、本実施の形態では１８個である。 The heat sink 390 is made of a heat conductive material. The heat sink 390 is a metal plate that extends one turn while forming a convex crest 391 in a direction away from the central axis of the heat sink 390 and a convex trough 392 in a direction approaching the central axis of the heat sink 390 by bending in a wave shape It is formed by. That is, the heat sink 390 is processed into a tubular shape by bending a bendable annular plate material into a wave shape. That is, the heat sink 390 is made of a metal plate that is bent into a wave shape and alternately has peaks 391 and valleys 392. The peaks 391 are on the outer side (outward), and the valleys 392 are on the inner side (inward). Make one lap for each. The number of peak portions 391 may be any number, but is 18 in this embodiment.
　周壁部３３１には、ヒートシンク３９０が筐体３３０の外側から固定される。具体的には、周壁部３３１の外側に、ヒートシンク３９０の谷部３９２が取り付けられる。周壁部３３１と山部３９１との間には、山部３９１の両端を出入口とする通気経路が形成される。即ち、周壁部３３１とヒートシンク３９０との間には、ヒートシンク３９０の筒軸方向の両端部が開口された通気経路が形成される。そのため、筐体３３０及びヒートシンク３９０の放熱性が向上する。 A heat sink 390 is fixed to the peripheral wall portion 331 from the outside of the housing 330. Specifically, a trough 392 of the heat sink 390 is attached to the outside of the peripheral wall 331. Between the peripheral wall part 331 and the peak part 391, a ventilation path having both ends of the peak part 391 as the entrance and exit is formed. That is, a ventilation path is formed between the peripheral wall portion 331 and the heat sink 390 in which both ends of the heat sink 390 in the cylinder axis direction are opened. Therefore, the heat dissipation of the housing 330 and the heat sink 390 is improved.
　本実施の形態では、ヒートシンク３９０の内側稜部がカシメ止めによって周壁部３３１に強固に取り付けられている。これにより、熱伝導効果と強度とが向上する。カシメの位置及び個数は、任意の位置及び個数でよいが、本実施の形態ではヒートシンク３９０の円周方向に沿って等間隔に３個の谷部３９２を選び、それら３個の谷部３９２の１個ずつでヒートシンク３９０の中心軸方向に沿って等間隔に４箇所カシメを設けている。よって、ヒートシンク３９０を周壁部３３１に連結するカシメの総数は１２個である。 In the present embodiment, the inner ridge portion of the heat sink 390 is firmly attached to the peripheral wall portion 331 by caulking. Thereby, a heat conduction effect and intensity | strength improve. The position and number of caulking may be any position and number, but in this embodiment, three valley portions 392 are selected at equal intervals along the circumferential direction of the heat sink 390, and the three valley portions 392 are arranged. Four caulkings are provided at equal intervals along the central axis direction of the heat sink 390 one by one. Therefore, the total number of crimps connecting the heat sink 390 to the peripheral wall portion 331 is twelve.
　なお、ヒートシンク３９０の内側稜部に沿って筐体３３０が圧入されることで筐体３３０にヒートシンク３９０が取り付けられてもよい。その場合、ヒートシンク３９０は、バネ性を有している必要がある。 Note that the heat sink 390 may be attached to the housing 330 by press-fitting the housing 330 along the inner ridge of the heat sink 390. In that case, the heat sink 390 needs to have a spring property.
　筐体３３０の管軸を含む断面において、ヒートシンク３９０は、蓋体３４０に近い側が縮径している。即ち、ヒートシンク３９０は、窄んでいる。 In the cross section including the tube axis of the housing 330, the heat sink 390 has a reduced diameter on the side close to the lid 340. That is, the heat sink 390 is constricted.
　筐体３３０の管軸を含む断面において、ヒートシンク３９０は、底壁部３３２に近い側が拡径している。 In the cross section including the tube axis of the housing 330, the heat sink 390 has an enlarged diameter on the side close to the bottom wall portion 332.
　本実施の形態では、山部３９１の両端が斜めに切り欠かれることで、山部３９１の長さがヒートシンク３９０の中心軸から離れるにつれて徐々に短くなる。即ち、筐体３３０の管軸を含む断面において、ヒートシンク３９０は、蓋体３４０に近い側の端部である上端部と底壁部３３２に近い側の端部である下端部とがＲ状に切り欠かれている。上端部の切り欠きは、天井材６００への取り付け性を向上させ、下端部の切り欠きは、空気の取り込み性を向上させる。よって、山部３９１の両端の少なくとも一方が斜めに切り欠かれていれば、少なくともいずれかの効果を得ることができる。 In the present embodiment, both ends of the peak portion 391 are notched obliquely, so that the length of the peak portion 391 gradually decreases as the distance from the central axis of the heat sink 390 increases. That is, in the cross section including the tube axis of the housing 330, the heat sink 390 has an R shape with an upper end portion that is an end portion closer to the lid body 340 and a lower end portion that is an end portion closer to the bottom wall portion 332. It is cut out. The cutout at the upper end improves the attachment property to the ceiling material 600, and the cutout at the lower end improves the air intake. Therefore, at least one of the effects can be obtained as long as at least one of both ends of the peak portion 391 is cut obliquely.
　山部３９１の両端の少なくとも一方が切り欠かれる大きさは、枠４００の円周方向において板バネ５００と重なる位置にあるもののほうが他の位置にあるものよりも大きいことが望ましい。即ち、板バネ５００と重なる位置にある山部３９１の両端のいずれかに形成される通気経路の入口は、空気が入りにくいため、他の位置にある山部３９１の両端のいずれかに形成される通気経路の入口よりも大きく開いていることが望ましい。 It is desirable that at least one of the both ends of the mountain portion 391 be cut out at a position where it overlaps with the leaf spring 500 in the circumferential direction of the frame 400 than at the other position. That is, the entrance of the ventilation path formed at either end of the peak portion 391 that overlaps with the leaf spring 500 is formed at either end of the peak portion 391 at another position because it is difficult for air to enter. It is desirable that the opening is larger than the entrance of the ventilation path.
　本実施の形態では、山部３９１の長さ方向の中央付近に開口部３９３が設けられる。開口部３９３から空気が出入りすることで、筐体３３０及びヒートシンク３９０の放熱性がより一層向上する。 In the present embodiment, the opening 393 is provided near the center of the mountain portion 391 in the length direction. When air enters and exits from the opening 393, the heat dissipation of the housing 330 and the heat sink 390 is further improved.
　ヒートシンク３９０は、照明装置１００としての組み立てに必要な構造、照明装置１００を天井に取り付ける際に必要な構造を考慮して部分的に切り欠かれてもよい。 The heat sink 390 may be partially cut away in consideration of a structure necessary for assembly as the lighting device 100 and a structure necessary when the lighting device 100 is attached to the ceiling.
　ヒートシンク３９０は、図示した形状以外に、放射状に立設させた形状、ピン形状、コルゲート形状等でもよく、押し出し又は絞り等、折り曲げ以外の成形法で製造されてもよい。ヒートシンク３９０の形状に応じて、周壁部３３１の形状も適宜変更することができる。即ち、周壁部３３１は、筒状であれば、円筒状に限らず、他の形状でもよい。 In addition to the illustrated shape, the heat sink 390 may have a radially standing shape, a pin shape, a corrugated shape, or the like, or may be manufactured by a molding method other than bending, such as extrusion or drawing. Depending on the shape of the heat sink 390, the shape of the peripheral wall portion 331 can be changed as appropriate. That is, the peripheral wall portion 331 is not limited to a cylindrical shape as long as it has a cylindrical shape, and may have another shape.

　出力電線３２０は、第１収容部３７１から隔壁３７３を越えて第２収容部３７２に入り、第２収容部３７２から第２収容部３７２の底壁に設けられた貫通孔３７４と底壁部３３２に設けられた貫通孔３３３とを通って収容体３７０と筐体３３０との外側に出る。 The output electric wire 320 enters the second housing portion 372 from the first housing portion 371 across the partition wall 373, and the through hole 374 and the bottom wall portion 332 provided in the bottom wall of the second housing portion 372 from the second housing portion 372. It passes through the through-hole 333 provided on the outer side of the container 370 and the housing 330.
　このように、本実施の形態では、電源基板３１０が収容されるスペースと、出力電線３２０が収容されるスペースとが別々に確保されているため、電源基板３１０の設置及び配線の作業が効率よく行える。 As described above, in this embodiment, the space for housing the power supply board 310 and the space for housing the output electric wire 320 are secured separately, so that the installation and wiring work of the power supply board 310 can be efficiently performed.

The column portion 375 protrudes from a location where the through hole in the bottom wall of the second housing portion 372 is provided, and fits into the through hole 333 provided in the bottom wall portion 332.
　出力電線３２０は、第２収容部３７２の底壁に設けられた貫通孔３７４から柱部３７５の中を通って収容体３７０と筐体３３０との外側に出る。 The output electric wire 320 passes through the pillar portion 375 from the through hole 374 provided in the bottom wall of the second housing portion 372 and goes out of the housing body 370 and the housing 330.
　隔壁３７３の一端には、出力電線３２０を通す凹部３７６が設けられる。 A recess 376 through which the output electric wire 320 passes is provided at one end of the partition wall 373.
　収容体３７０は、さらに、中空のボス部３７７を有する。ボス部３７７は、第２収容部３７２の底壁と一体成形される。第２収容部３７２の底壁には、ボス部の中につながるネジ穴３７８が設けられる。底壁部３３２には、第２収容部３７２の底壁に設けられたネジ穴３７８を介して収容体３７０がネジ止めされる。 The container 370 further has a hollow boss portion 377.

The container 370 is screwed to the bottom wall portion 332 through a screw hole 378 provided in the bottom wall of the second housing portion 372.
　収容体３７０は、さらに、橋部３７９を有する。橋部３７９は、第１収容部３７１の周壁の一端から突出し、周壁部３３１に設けられた切り欠き３３５に嵌る。切り欠き３３５の代わりに、貫通孔が周壁部３３１に設けられる場合、橋部３７９は、その貫通孔に嵌る。 The container 370 further has a bridge portion 379. The bridge portion 379 protrudes from one end of the peripheral wall of the first housing portion 371 and fits into a notch 335 provided in the peripheral wall portion 331. When a through hole is provided in the peripheral wall portion 331 instead of the notch 335, the bridge portion 379 fits into the through hole.
　入力電線３６０は、収容体３７０と筐体３３０との外側から橋部３７９に設けられた溝３８０を通って第１収容部３７１に入る。即ち、入力電線３６０は、周壁部３３１に設けられた切り欠き３３５を通って筐体３３０の外側から筐体３３０の内側に入る。なお、入力電線３６０を通すために、溝３８０の代わりに、穴が橋部３７９に設けられてもよい。 The input electric wire 360 enters the first accommodating portion 371 through the groove 380 provided in the bridge portion 379 from the outside of the accommodating body 370 and the housing 330. That is, the input electric wire 360 enters the inside of the housing 330 from the outside of the housing 330 through the notch 335 provided in the peripheral wall portion 331. Note that a hole may be provided in the bridge portion 379 instead of the groove 380 in order to pass the input electric wire 360.
　本実施の形態では、収容体３７０の外周面３８１が周壁部３３１の中心軸方向に対して斜めに延びることで収容体３７０と周壁部３３１との間に隙間が形成される。これにより、筐体３３０から収容体３７０への伝熱を抑制することができる。 In the present embodiment, the outer peripheral surface 381 of the container 370 extends obliquely with respect to the central axis direction of the peripheral wall 331, so that a gap is formed between the container 370 and the peripheral wall 331. Thereby, the heat transfer from the housing | casing 330 to the container 370 can be suppressed.
　収容体３７０の外周面３８１と周壁部３３１の中心軸とのなす角度は、０．１度以上であることが望ましい。 The angle formed between the outer peripheral surface 381 of the container 370 and the central axis of the peripheral wall portion 331 is preferably 0.1 degrees or more.

A gap may be formed between the container 370 and the peripheral wall 331 by adopting a configuration that extends obliquely.
　図示していないが、本実施の形態において、光源ユニット２００は、筐体３３０の外側からカシメ又はネジによって底壁部３３２に連結される。そして、カシメ又はネジの筐体３３０の内側に突出する部分によって収容体３７０の底面が押し上げられることで収容体３７０と底壁部３３２との間にも隙間が形成される。これにより、筐体３３０から収容体３７０への伝熱を抑制することができる。 Although not shown, in the present embodiment, the light source unit 200 is connected to the bottom wall portion 332 by caulking or screws from the outside of the housing 330.

The rib 242 located in the wiring path of the output electric wire 320 that is extended to the connector 212 of the light source substrate 210 through the concave portion 386 of the column portion 375 of the container 370 is notched in a concave shape. In addition, an inner peripheral wall 243 that rises from the periphery of the circular opening 241 is formed on the back side of the reflector 240. Thereby, the output electric wire 320 drawn out from the column part 375 and connected to the connector 212 can be wired on the back side of the reflecting plate 240 so as not to disturb the emission of light from the light emitting element 211. The number of ribs 242 may be any number, but in the present embodiment, it is 11 and 6 ribs 242 are cut out.
　反射板２４０の外周部には、枠４００を取り付けるための取り付け機構が形成されている。取り付け機構は、１組のフック２４４及びラッチ２４５からなる。取り付け機構は、枠４００が取り付けられた状態でストレスフリー状態を維持している。 An attachment mechanism for attaching the frame 400 is formed on the outer periphery of the reflector 240. The attachment mechanism consists of a set of hooks 244 and latches 245. The attachment mechanism maintains a stress-free state with the frame 400 attached.

　図２４を参照して、本実施の形態に係る装置である照明装置１００の構成を説明する。 *** Explanation of configuration ***
With reference to FIG. 24, the structure of the illuminating device 100 which is an apparatus which concerns on this Embodiment is demonstrated.
　本実施の形態では、ヒートシンク３９０の構成が、実施の形態１における電源ユニット３００のヒートシンク３９０の構成と異なる。電源ユニット３００のその他の構成については、実施の形態１における電源ユニット３００の構成と同じである。照明装置１００の電源ユニット３００以外の構成についても、実施の形態１に係る照明装置１００の構成と同じである。 In the present embodiment, the configuration of the heat sink 390 is different from the configuration of the heat sink 390 of the power supply unit 300 in the first embodiment. Other configurations of power supply unit 300 are the same as those of power supply unit 300 in the first embodiment. The configuration of lighting apparatus 100 other than power supply unit 300 is the same as that of lighting apparatus 100 according to Embodiment 1.
　図２５及び図２６及び図２７及び図２８を参照して、ヒートシンク３９０の詳細について説明する。図２７及び図２８では、空気の流れを矢印で示している。 Details of the heat sink 390 will be described with reference to FIG. 25, FIG. 26, FIG. 27, and FIG. In FIG.27 and FIG.28, the flow of air is shown by the arrow.
　実施の形態１では、図７及び図８に示したように、ヒートシンク３９０の山部３９１の長さ方向の中央付近に開口部３９３が設けられるが、本実施の形態では、開口部３９３が設けられない。そのため、放熱面積が増え、放熱効率が向上する。 In the first embodiment, as shown in FIGS. 7 and 8, the opening 393 is provided near the center in the length direction of the peak portion 391 of the heat sink 390. However, in this embodiment, the opening 393 is provided. I can't. Therefore, the heat radiation area is increased and the heat radiation efficiency is improved.
　筐体３３０の周壁部３３１とヒートシンク３９０の山部３９１との間には、実施の形態１と同じように、山部３９１の両端を出入口とする通気経路が形成されるが、本実施の形態では、開口部３９３がないため、通気経路の途中で空気が出入りすることはない。そのため、筐体３３０とヒートシンク３９０との間に空気の乱流が発生せず、よりスムーズに空気を移動させることができるので、放熱効率が向上する。 A vent path is formed between the peripheral wall portion 331 of the housing 330 and the peak portion 391 of the heat sink 390 in the same manner as in the first embodiment, with both ends of the peak portion 391 as inlets and outlets. Then, since there is no opening part 393, air does not enter / exit in the middle of a ventilation path. Therefore, air turbulence does not occur between the housing 330 and the heat sink 390, and the air can be moved more smoothly, so that the heat dissipation efficiency is improved.
　ヒートシンク３９０は、実施の形態１と同じように、プレス加工で成形される。 The heat sink 390 is formed by press work as in the first embodiment.
　＊＊＊効果の説明＊＊＊

In the present embodiment, in particular, when the installation environment of lighting device 100 is an environment in which a large amount of air flow is unlikely to occur, the heat dissipation of lighting device 100 is higher than that in the first embodiment.
　実施の形態１では、照明装置１００の外殻部であるヒートシンク３９０の山部３９１に開口部３９３を設けるので、２次加工等によって開口部３９３の周縁部にＲ面加工、Ｃ面加工等のエッジ処理を施すことが望ましい。また、実施の形態１では、開口部３９３の周縁部にバリが残存するおそれがあるので、バリ取りを施すことが望ましい。一方、本実施の形態では、こういった２次的な加工を施す必要がなくなる。このため、照明装置１００の製造環境及び設置環境に加工屑を飛散させるおそれがなくなり、照明装置１００の製造環境及び設置環境の絶縁性能を悪化させる要因も排除できる。 In Embodiment 1, since the opening 393 is provided in the peak portion 391 of the heat sink 390 that is the outer shell portion of the lighting device 100, the peripheral portion of the opening 393 is subjected to R surface processing, C surface processing, or the like by secondary processing or the like. It is desirable to perform edge processing. In the first embodiment, burrs may remain on the peripheral edge of the opening 393, so it is desirable to deburr. On the other hand, in this embodiment, it is not necessary to perform such secondary processing. For this reason, there is no possibility that the processing waste is scattered in the manufacturing environment and the installation environment of the lighting device 100, and the factor that deteriorates the insulation performance of the manufacturing environment and the installation environment of the lighting device 100 can be eliminated.

　以下では、蓋体３４０の詳細について説明する。 Hereinafter, the details of the lid 340 will be described.
　蓋体３４０は、長手状である。蓋体３４０は、閉塞部７１１と、固定部３４２とを有する。筐体３３０の底壁部３３２が、筐体３３０の周壁部３３１の一端を塞ぐのに対し、閉塞部７１１は、周壁部３３１の他端を塞ぐ。固定部３４２には、端子台３５０が固定される。閉塞部７１１と固定部３４２は、蓋体３４０の中心軸Ｌ１の方向、即ち、蓋体３４０の長手方向に沿って並ぶ。本実施の形態において、固定部３４２は、閉塞部７１１と一体成形される。閉塞部７１１は、固定部３４２につながる部分が矩形の板状に形成され、固定部３４２から離れた部分が半円形の板状に形成される。 The lid body 340 has a longitudinal shape. The lid body 340 includes a closing part 711 and a fixing part 342. The bottom wall portion 332 of the housing 330 closes one end of the peripheral wall portion 331 of the housing 330, while the closing portion 711 closes the other end of the peripheral wall portion 331. A terminal block 350 is fixed to the fixing portion 342. The closing portion 711 and the fixing portion 342 are arranged along the direction of the central axis L1 of the lid body 340, that is, along the longitudinal direction of the lid body 340. In the present embodiment, the fixing portion 342 is integrally formed with the closing portion 711. The blocking portion 711 is formed in a rectangular plate shape at a portion connected to the fixing portion 342, and is formed in a semicircular plate shape at a portion away from the fixing portion 342.
　閉塞部７１１において、１対の連結具７０１は、蓋体３４０の中心軸Ｌ１に対して角度θの直線上で対向する位置、即ち、蓋体３４０の長手方向に対して斜めの方向に沿って対向する位置で蓋体３４０を筐体３３０に連結する。角度θは、０度よりも大きく、１８０度よりも小さい任意の角度でよいが、本実施の形態では４５度である。つまり、本実施の形態において、１対の連結具７０１は、閉塞部７１１における、蓋体３４０の長手方向に対して４５度の方向に沿って対向する位置で蓋体３４０を筐体３３０に連結する。 In the closing portion 711, the pair of coupling tools 701 are opposed to the central axis L <b> 1 of the lid 340 on a straight line having an angle θ, that is, along a direction oblique to the longitudinal direction of the lid 340. The lid body 340 is connected to the housing 330 at the facing position. The angle θ may be any angle larger than 0 degree and smaller than 180 degrees, but is 45 degrees in the present embodiment. In other words, in the present embodiment, the pair of coupling tools 701 couples the lid 340 to the housing 330 at a position in the closing portion 711 facing the longitudinal direction of the lid 340 along the direction of 45 degrees. To do.
　蓋体３４０は、さらに、フランジ部３４５を有する。フランジ部３４５は、固定部３４２と同じように、閉塞部７１１と一体成形される。フランジ部３４５は、閉塞部７１１の半円形の板状になっている部分の外周部分から閉塞部７１１の外側に突出する。１対の連結具７０１のうち、一方の連結具７０１は、フランジ部３４５に設けられたネジ穴を介して、筐体３３０の一方のフランジ部３３４に設けられたネジ穴にねじ込まれる。他方の連結具７０１は、閉塞部７１１の矩形の板状になっている部分において、蓋体３４０の中心軸Ｌ１に対して角度θの直線上でフランジ部３４５のネジ穴と対向する位置に設けられたネジ穴を介して、筐体３３０の他方のフランジ部３３４に設けられたネジ穴にねじ込まれる。これにより、蓋体３４０が筐体３３０のフランジ部３３４にネジ止めされる。 The lid body 340 further has a flange portion 345. The flange portion 345 is integrally formed with the closing portion 711 in the same manner as the fixing portion 342. The flange portion 345 protrudes to the outside of the blocking portion 711 from the outer peripheral portion of the semicircular plate-shaped portion of the closing portion 711. Of the pair of connectors 701, one connector 701 is screwed into a screw hole provided in one flange portion 334 of the housing 330 through a screw hole provided in the flange portion 345. The other connector 701 is provided at a position facing the screw hole of the flange portion 345 on a straight line having an angle θ with respect to the central axis L1 of the lid 340 in the rectangular plate-like portion of the closing portion 711. It is screwed into the screw hole provided in the other flange portion 334 of the housing 330 through the formed screw hole. As a result, the lid 340 is screwed to the flange portion 334 of the housing 330.

・ネジ止めは、蓋体３４０への応力を最大限支え得る位置で行う。
・ネジ止めは、端子台３５０へ配線時の応力を最大限支え得る位置で行う。 *** Explanation of effects ***
In the present embodiment, the lid 340 is fixed to the flange portion 334 using a connector 701 that is two screws, but the screwing position is for reducing the size of the power supply unit 300 and the lighting device 100. In addition, it is determined to satisfy the following requirements.
-Screwing is performed at a position where it does not become an obstacle when the lighting device 100 is attached to the ceiling or the like.
Screwing is performed at a position that does not hinder the wiring of the input wire 360 that electrically connects the terminal block 350 and the power supply substrate 310. Specifically, screwing is performed at a position that does not interfere with the end of the input electric wire 360.
-Screwing is performed at a position where the stress on the lid 340 can be supported to the maximum.
-Screwing is performed at a position where the stress during wiring to the terminal block 350 can be supported to the maximum.
　本実施の形態では、蓋体３４０の端子台３５０が張り出す向きに沿った方向である長手方向に対して概ね４５度の向きに、軸対象の２つの位置にネジ穴が設けられ、それぞれのネジ穴に連結具７０１をねじ込むことで蓋体３４０をフランジ部３３４に固定している。そのため、上記の条件をバランスよく満たすことができる。なお、長手方向に対する角度は、それぞれ異なる角度でもよい。また、ネジ止めの位置は、２箇所に限らず、１箇所又は３箇所以上であってもよい。筐体３３０のフランジ部３３４の個数は、ネジ止めの箇所の数に合わせて適宜変更されるものとする。 In the present embodiment, screw holes are provided at two positions of the axial object in a direction of approximately 45 degrees with respect to the longitudinal direction, which is a direction along the direction in which the terminal block 350 of the lid 340 protrudes. The lid 340 is fixed to the flange portion 334 by screwing the connector 701 into the screw hole. Therefore, the above conditions can be satisfied with a good balance. The angle with respect to the longitudinal direction may be different from each other. Moreover, the position of screwing is not limited to two, and may be one or three or more. It is assumed that the number of flange portions 334 of the housing 330 is appropriately changed according to the number of screwed portions.
　本実施の形態によれば、照明装置１００の組み立て時に、入力電線３６０の配線が妨げられない。また、照明装置１００の取り付け時に、作業者が蓋体３４０を持ってしまうことで蓋体３４０に加わる応力、或いは、配線作業によって蓋体３４０に加わる応力を最大限吸収することができる。 According to the present embodiment, the wiring of the input electric wire 360 is not hindered when the lighting device 100 is assembled. Further, when the lighting device 100 is attached, the stress applied to the lid 340 by the operator holding the lid 340 or the stress applied to the lid 340 due to the wiring work can be absorbed to the maximum.
　本実施の形態では、蓋体３４０の端子台３５０が取り付けられる部分を光源側にオフセットさせている。このため、固定具７０２が上方に突き出すことによって照明装置１００の高さ寸法が大きくなることを防げる。即ち、本実施の形態によれば、照明装置１００の高さを低く抑えることができ、高さ方向において狭小の設置環境にも照明装置１００を対応させることができる。実施の形態２及び実施の形態３でも、蓋体３４０の端子台３５０が取り付けられる部分を光源側にオフセットさせているため、同じ効果が得られる。なお、蓋体３４０の端子台３５０が取り付けられる部分の全体を光源側にオフセットさせなくても、少なくとも蓋体３４０の固定具７０２が配置される部分を光源側にオフセットさせていれば、同じ効果が得られる。 In the present embodiment, the portion of the lid 340 to which the terminal block 350 is attached is offset to the light source side. For this reason, it can prevent that the height dimension of the illuminating device 100 becomes large because the fixing tool 702 protrudes upwards. That is, according to the present embodiment, the height of the lighting device 100 can be kept low, and the lighting device 100 can be adapted to a narrow installation environment in the height direction. In the second embodiment and the third embodiment, the same effect can be obtained because the portion to which the terminal block 350 of the lid 340 is attached is offset to the light source side. Note that the same effect can be obtained as long as at least the portion of the lid 340 where the fixture 702 is disposed is offset to the light source side without offsetting the entire portion of the lid 340 to which the terminal block 350 is attached to the light source side. Is obtained.
　本実施の形態では、蓋体３４０となる金属の板を部分的に搾ることで段差７２０が形成されている。このため、蓋体３４０の蓋部の曲げに対する強度が増す。実施の形態２及び実施の形態３でも、蓋体３４０となる金属の板を部分的に搾っているため、同じ効果が得られる。 In this embodiment, the level difference 720 is formed by partially squeezing a metal plate to be the lid 340. For this reason, the intensity | strength with respect to the bending of the cover part of the cover body 340 increases. In the second embodiment and the third embodiment, the same effect can be obtained because the metal plate to be the lid 340 is partially squeezed.

　実施の形態１及び実施の形態９と同じように、フランジ部３４５は、閉塞部７１１の半円形の板状になっている部分の外周部分から閉塞部７１１の外側に突出する。１対の連結具７０１のうち、一方の連結具７０１は、フランジ部３４５に設けられたネジ穴７０３を介して、筐体３３０の一方のフランジ部３３４に設けられたネジ穴にねじ込まれる。他方の連結具７０１は、閉塞部７１１の矩形の板状になっている部分において、蓋体３４０の中心軸Ｌ１に対して角度θの直線上でフランジ部３４５のネジ穴７０３と対向する位置に設けられたネジ穴７０３を介して、筐体３３０の他方のフランジ部３３４に設けられたネジ穴にねじ込まれる。これにより、蓋体３４０が筐体３３０のフランジ部３３４にネジ止めされる。 As in the first and ninth embodiments, the flange portion 345 protrudes from the outer peripheral portion of the semicircular plate-like portion of the closing portion 711 to the outside of the closing portion 711. Of the pair of connectors 701, one connector 701 is screwed into a screw hole provided in one flange portion 334 of the housing 330 via a screw hole 703 provided in the flange portion 345. The other connector 701 is located at a position facing the screw hole 703 of the flange portion 345 on a straight line having an angle θ with respect to the central axis L1 of the lid 340 in the rectangular plate-like portion of the closing portion 711.

As a result, the lid 340 is screwed to the flange portion 334 of the housing 330.
　本実施の形態では、蓋体３４０の短手方向の一端から他端まで、平面視直線状の段差７２０が設けられる。蓋体３４０は、下面における、上面の高い段７２１に対応する部分で周壁部３３１の他端を塞ぐ。また、蓋体３４０は、下面における、少なくとも一部が上面の低い段７２２に対応する部分に端子台３５０が固定される。具体的には、蓋体３４０は、下面における、全部が上面の低い段７２２に対応する部分に端子台３５０が固定される。つまり、本実施の形態では、蓋体３４０の高い段７２１が閉塞部７１１に相当し、蓋体３４０の低い段７２２が固定部３４２に相当する。 In the present embodiment, a step 720 that is linear in a plan view is provided from one end to the other end of the lid 340 in the short direction. The lid body 340 closes the other end of the peripheral wall portion 331 at a portion corresponding to the step 721 having a high upper surface on the lower surface. In addition, the terminal block 350 is fixed to a portion of the lower surface of the lid 340 corresponding to the step 722 where at least a part of the lower surface is lower.

　図４０を参照して、収容体３７０の構成を説明する。 The configuration of the container 370 will be described with reference to FIG.
　実施の形態１と同じように、収容体３７０は、橋部３７９を有する。橋部３７９は、第１収容部３７１の周壁の一端から突出し、筐体３３０の周壁部３３１に設けられた切り欠き３３５に嵌る。入力電線３６０は、収容体３７０と筐体３３０との外側から橋部３７９に設けられた溝３８０を通って第１収容部３７１に入る。即ち、入力電線３６０は、周壁部３３１に設けられた切り欠き３３５を通って筐体３３０の外側から筐体３３０の内側に入る。 As in the first embodiment, the container 370 has a bridge portion 379. The bridge portion 379 protrudes from one end of the peripheral wall of the first housing portion 371 and fits into a notch 335 provided in the peripheral wall portion 331 of the housing 330. The input electric wire 360 enters the first housing portion 371 through the groove 380 provided in the bridge portion 379 from the outside of the housing body 370 and the housing 330. That is, the input electric wire 360 enters the inside of the housing 330 from the outside of the housing 330 through the notch 335 provided in the peripheral wall portion 331.
　実施の形態１と同じように、第１収容部３７１には、収容体３７０の管軸方向に沿って内部空間を仕切るための仕切り壁３８２が設けられている。仕切り壁３８２は、第１収容部３７１の内部空間を仕切って、橋部３７９から遠い第１収納室３８３と、橋部３７９に近い第２収納室３８７とを形成する。仕切り壁３８２の一端には、橋部３７９から第２収納室３８７及び仕切り壁３８２を越えて第１収納室３８３へ入力電線３６０を通過させる凹部３８９が形成されている。 As in the first embodiment, the first housing portion 371 is provided with a partition wall 382 for partitioning the internal space along the tube axis direction of the housing 370. The partition wall 382 partitions the internal space of the first storage portion 371 and forms a first storage chamber 383 far from the bridge portion 379 and a second storage chamber 387 close to the bridge portion 379. A recess 389 is formed at one end of the partition wall 382 to allow the input electric wire 360 to pass from the bridge portion 379 to the first storage chamber 383 through the second storage chamber 387 and the partition wall 382.
　実施の形態１と同じように、橋部３７９に設けられた溝３８０の長さは、仕切り壁３８２の一端に形成された凹部３８９の長さよりも長い。一方、橋部３７９に設けられた溝３８０の幅は、仕切り壁３８２の一端に形成された凹部３８９の幅と同じである。橋部３７９に設けられた溝３８０の深さも、仕切り壁３８２の一端に形成された凹部３８９の深さと同じである。橋部３７９に設けられた溝３８０の形状も、仕切り壁３８２の一端に形成された凹部３８９の形状と同じである。溝３８０及び凹部３８９の形状は、実施の形態１では、図１０及び図１１に示したような、幅寸法が深さ寸法よりも大きい角溝状であるが、本実施の形態では、図４０に示したようなＶ字溝状である。なお、溝３８０及び凹部３８９の形状は、他の形状でもよく、具体的には、図４１に示すような半円溝状、図４２に示すような、深さ寸法が幅寸法よりも大きい角溝状、図示していない逆Ｍ字溝状、Ｗ字溝状等であってもよい。溝３８０及び凹部３８９の形状が逆Ｍ字溝状又はＷ字溝状である場合、最も深くなる２箇所で配線経路を分散することができる。また、溝３８０及び凹部３８９は、入力電線３６０の張力止めを兼ねてもよく、その場合、溝３８０及び凹部３８９の幅は、入力電線３６０の被覆を含む外径よりやや狭いものとする。 As in the first embodiment, the length of the groove 380 provided in the bridge portion 379 is longer than the length of the concave portion 389 formed at one end of the partition wall 382. On the other hand, the width of the groove 380 provided in the bridge portion 379 is the same as the width of the concave portion 389 formed at one end of the partition wall 382. The depth of the groove 380 provided in the bridge portion 379 is also the same as the depth of the concave portion 389 formed at one end of the partition wall 382. The shape of the groove 380 provided in the bridge portion 379 is also the same as the shape of the concave portion 389 formed at one end of the partition wall 382. In the first embodiment, the shape of the groove 380 and the concave portion 389 is a square groove shape whose width dimension is larger than the depth dimension as shown in FIGS. 10 and 11, but in this embodiment, FIG.

It may be a groove shape, a reverse M-shaped groove shape, a W-shaped groove shape or the like not shown. When the shape of the groove 380 and the concave portion 389 is an inverted M-shaped groove shape or a W-shaped groove shape, the wiring paths can be dispersed at the two deepest locations. Further, the groove 380 and the concave portion 389 may also serve as a tension stopper for the input electric wire 360. In this case, the width of the groove 380 and the concave portion 389 is slightly narrower than the outer diameter including the covering of the input electric wire 360.
　橋部３７９において、入力電線３６０が通過又は交差する角部には、Ｒ面加工、Ｃ面加工等のエッジ処理が施されることが望ましい。 In the bridge portion 379, it is desirable that edge processing such as R surface processing, C surface processing, or the like is performed on a corner portion where the input electric wire 360 passes or intersects.
　仕切り壁３８２の一端に形成された凹部３８９の深さは、橋部３７９に設けられた溝３８０の深さより深くてもよい。その場合、入力電線３６０の長さを短くすることができる。 The depth of the recess 389 formed at one end of the partition wall 382 may be deeper than the depth of the groove 380 provided in the bridge portion 379. In that case, the length of the input electric wire 360 can be shortened.

The configuration of the apparatus according to the present embodiment and the effects of the present embodiment will be described in order. Differences from the first embodiment will be mainly described.
　＊＊＊構成の説明＊＊＊
　本実施の形態では、電源ユニット３００の収容体３７０の構成が、実施の形態１における電源ユニット３００の収容体３７０の構成と異なる。電源ユニット３００のその他の構成については、実施の形態１における電源ユニット３００の構成と同じである。照明装置１００の電源ユニット３００以外の構成についても、実施の形態１に係る照明装置１００の構成と同じである。 *** Explanation of configuration ***
In the present embodiment, the configuration of container 370 of power supply unit 300 is different from the configuration of container 370 of power supply unit 300 in the first embodiment. Other configurations of power supply unit 300 are the same as those of power supply unit 300 in the first embodiment. The configuration of lighting apparatus 100 other than power supply unit 300 is the same as that of lighting apparatus 100 according to Embodiment 1.
　図４３及び図４４を参照して、収容体３７０の構成を説明する。 The configuration of the container 370 will be described with reference to FIGS. 43 and 44.
　実施の形態１と同じように、収容体３７０は、橋部３７９を有する。橋部３７９は、第１収容部３７１の周壁の一端から突出し、筐体３３０の周壁部３３１に設けられた切り欠き３３５に嵌る。入力電線３６０は、収容体３７０と筐体３３０との外側から橋部３７９に設けられた溝３８０を通って第１収容部３７１に入る。即ち、入力電線３６０は、周壁部３３１に設けられた切り欠き３３５を通って筐体３３０の外側から筐体３３０の内側に入る。 As in the first embodiment, the container 370 has a bridge portion 379. The bridge portion 379 protrudes from one end of the peripheral wall of the first housing portion 371 and fits into a notch 335 provided in the peripheral wall portion 331 of the housing 330. The input electric wire 360 enters the first housing portion 371 through the groove 380 provided in the bridge portion 379 from the outside of the housing body 370 and the housing 330. That is, the input electric wire 360 enters the inside of the housing 330 from the outside of the housing 330 through the notch 335 provided in the peripheral wall portion 331.
　実施の形態１と同じように、第１収容部３７１には、収容体３７０の管軸方向に沿って内部空間を仕切るための仕切り壁３８２が設けられている。仕切り壁３８２は、第１収容部３７１の内部空間を仕切って、橋部３７９から遠い第１収納室３８３と、橋部３７９に近い第２収納室３８７とを形成する。仕切り壁３８２の一端には、橋部３７９から第２収納室３８７及び仕切り壁３８２を越えて第１収納室３８３へ入力電線３６０を通過させる凹部３８９が形成されている。 As in the first embodiment, the first housing portion 371 is provided with a partition wall 382 for partitioning the internal space along the tube axis direction of the housing 370. The partition wall 382 partitions the internal space of the first storage portion 371 and forms a first storage chamber 383 far from the bridge portion 379 and a second storage chamber 387 close to the bridge portion 379. A recess 389 is formed at one end of the partition wall 382 to allow the input electric wire 360 to pass from the bridge portion 379 to the first storage chamber 383 through the second storage chamber 387 and the partition wall 382.
　本実施の形態では、橋部３７９が仕切り壁３８２の一端まで延びて、仕切り壁３８２の一端に形成された凹部３８９に嵌っている。 In this embodiment, the bridge portion 379 extends to one end of the partition wall 382 and fits into a recess 389 formed at one end of the partition wall 382.
　橋部３７９は、実施の形態１では第１収容部３７１と一体であるが、本実施の形態では第１収容部３７１とは別体である。第１収容部３７１の周壁の一端には、橋部３７９を第１収容部３７１の内側から第１収容部３７１の外側へ通す切り欠き８０１が設けられている。 Bridge portion 379 is integral with first housing portion 371 in Embodiment 1, but is separate from first housing portion 371 in the present embodiment. At one end of the peripheral wall of the first housing portion 371, a notch 801 is provided to pass the bridge portion 379 from the inside of the first housing portion 371 to the outside of the first housing portion 371.
　このように、本実施の形態では、橋部３７９が、仕切り壁３８２の一端に形成された凹部３８９と、第１収容部３７１の周壁の一端に設けられた切り欠き８０１とに嵌るように、第１収容部３７１に取り付けられる。 Thus, in the present embodiment, the bridge portion 379 is fitted into the recess 389 formed at one end of the partition wall 382 and the notch 801 provided at one end of the peripheral wall of the first housing portion 371. It is attached to the first housing part 371.
　なお、溝３８０の形状は、幅寸法が深さ寸法よりも大きい角溝状に限らず、Ｖ字溝状、半円溝状、深さ寸法が幅寸法よりも大きい角溝状、逆Ｍ字溝状、Ｗ字溝状といった任意の形状でよい。また、溝３８０は、入力電線３６０の張力止めを兼ねてもよく、その場合、溝３８０の幅は、入力電線３６０の被覆を含む外径よりやや狭いものとする。 The shape of the groove 380 is not limited to a square groove shape whose width dimension is larger than the depth dimension, but is a V-shaped groove shape, a semicircular groove shape, a square groove shape whose depth dimension is larger than the width dimension, or an inverted M shape. Any shape such as a groove shape or a W-shaped groove shape may be used. The groove 380 may also serve as a tension stopper for the input electric wire 360. In this case, the width of the groove 380 is slightly narrower than the outer diameter including the covering of the input electric wire 360.
　図４５に示すように、入力電線３６０を通すために、溝３８０の代わりに、穴８０２が橋部３７９に設けられてもよい。即ち、橋部３７９は、筒状でもよい。具体的には、橋部３７９は、角筒状でもよいし、円筒状でもよい。 45, a hole 802 may be provided in the bridge portion 379 instead of the groove 380 to allow the input electric wire 360 to pass therethrough. That is, the bridge portion 379 may be cylindrical. Specifically, the bridge portion 379 may have a rectangular tube shape or a cylindrical shape.
　仕切り壁３８２が第１収容部３７１に着脱自在に取り付けられる構成を採用してもよい。その場合、橋部３７９が仕切り壁３８２と一体に形成されてもよい。 A configuration in which the partition wall 382 is detachably attached to the first housing portion 371 may be employed. In that case, the bridge portion 379 may be formed integrally with the partition wall 382.
　橋部３７９は、蓋体３４０と一体に形成されてもよい。 The bridge portion 379 may be formed integrally with the lid body 340.
　＊＊＊効果の説明＊＊＊
　本実施の形態では、実施の形態１と同じように、橋部３７９があることで、入力電線３６０が筐体３３０のシャープエッジに触れて断線したり、地絡したりすることを防止できる。 *** Explanation of effects ***
In the present embodiment, as in the first embodiment, the presence of the bridge portion 379 can prevent the input electric wire 360 from touching the sharp edge of the housing 330 and causing a ground fault.
　本実施の形態では、橋部３７９を別部材とし、筐体３３０の周壁部３３１、第２収納室３８７の周壁、仕切り壁３８２を跨ぐように取り付ける構成を採用している。このため、収容体３７０の形状を単純な筒状とし、成形用の金型を簡素なものにすることができる。また、収容体３７０の剛性、即ち、構造強度が増す。さらに、収容体３７０は、管軸方向と垂直な方向に突出する部分がなくなるため、組み立て作業中等に橋部３７９が他の部材に引っ掛かることもなくなる。 In the present embodiment, a structure is adopted in which the bridge portion 379 is a separate member and is mounted so as to straddle the peripheral wall portion 331 of the housing 330, the peripheral wall of the second storage chamber 387, and the partition wall 382. For this reason, the shape of the container 370 can be a simple cylinder, and the molding die can be simplified. Further, the rigidity of the container 370, that is, the structural strength is increased. Furthermore, since the container 370 has no portion protruding in the direction perpendicular to the tube axis direction, the bridge portion 379 is not caught by another member during an assembly operation or the like.

　本実施の形態では、収容体３７０の外側から第１収容部３７１の周壁を越えて第２収納室３８７へ電線８１０を通過させる凹部８０３が、第１収容部３７１の周壁の一端に設けられた切り欠き８０１の途中に形成されている。具体的には、切り欠き８０１の中央部がさらに深く切り欠かれることで凹部８０３が形成されている。 In the present embodiment, a recess 803 that allows the electric wire 810 to pass from the outside of the housing 370 beyond the peripheral wall of the first storage portion 371 to the second storage chamber 387 is provided at one end of the peripheral wall of the first storage portion 371. It is formed in the middle of the notch 801. Specifically, the recess 803 is formed by further deepening the center of the notch 801.
　本実施の形態では、橋部３７９があることで、入力電線３６０の配線経路と、別の電線８１０の配線経路とが仕切られるため、配線作業をスムーズに行うことができる。 In the present embodiment, since there is a bridge portion 379, the wiring route of the input electric wire 360 and the wiring route of another electric wire 810 are partitioned, so that the wiring work can be performed smoothly.

　本実施の形態について、主に実施の形態１２との差異を説明する。 Embodiment 14 FIG.
In the present embodiment, differences from the twelfth embodiment will be mainly described.
　本実施の形態において、電源ユニット３００は、入力電線３６０とは別の電線８１０を備える。 In the present embodiment, the power supply unit 300 includes an electric wire 810 that is different from the input electric wire 360.
　電線８１０は、第２収納室３８７に収納される制御基板等と端子台３５０とを電気接続することで、外部電源から制御回路等への電力の入力経路となる。 The electric wire 810 serves as an electric power input path from the external power source to the control circuit and the like by electrically connecting the control board and the like stored in the second storage chamber 387 and the terminal block 350.
　本実施の形態では、収容体３７０の構成が、実施の形態１２における収容体３７０の構成と異なる。 In the present embodiment, the configuration of the container 370 is different from the configuration of the container 370 in the twelfth embodiment.
　図４８及び図４９を参照して、収容体３７０の構成を説明する。 The configuration of the container 370 will be described with reference to FIGS. 48 and 49.
　本実施の形態において、収容体３７０は、橋部３７９とは別の橋部８０４を有する。別の橋部８０４は、橋部３７９と重なって第１収容部３７１の周壁の一端から突出し、筐体３３０の周壁部３３１に設けられた切り欠き３３５に嵌る。橋部３７９は、第１収容部３７１とは別体であるが、別の橋部８０４は、第１収容部３７１と一体である。 In this embodiment, the container 370 has a bridge portion 804 that is different from the bridge portion 379. Another bridge portion 804 overlaps with the bridge portion 379 and protrudes from one end of the peripheral wall of the first housing portion 371 and fits into a notch 335 provided in the peripheral wall portion 331 of the housing 330. The bridge portion 379 is separate from the first housing portion 371, but the other bridge portion 804 is integral with the first housing portion 371.
　電線８１０は、収容体３７０と筐体３３０との外側から別の橋部８０４に設けられた溝８０５を通って第２収納室３８７に入る。なお、電線８１０を通すために、溝８０５の代わりに、穴が別の橋部８０４に設けられてもよい。 The electric wire 810 enters the second storage chamber 387 from the outside of the housing 370 and the housing 330 through the groove 805 provided in another bridge 804. In order to pass the electric wire 810, a hole may be provided in another bridge portion 804 instead of the groove 805.
　本実施の形態では、橋部３７９及び別の橋部８０４があることで、多層構造の配線経路が構成されるため、配線作業をスムーズに行うことができる。 In this embodiment, since there are the bridge portion 379 and the other bridge portion 804, a wiring path having a multilayer structure is configured, so that the wiring work can be performed smoothly.
　実施の形態１５．
　本実施の形態について、主に実施の形態１との差異を説明する。 Embodiment 15 FIG.
In the present embodiment, differences from the first embodiment will be mainly described.
　本実施の形態では、電源ユニット３００の収容体３７０の構成が、実施の形態１における電源ユニット３００の収容体３７０の構成と異なる。電源ユニット３００のその他の構成については、実施の形態１における電源ユニット３００の構成と同じである。照明装置１００の電源ユニット３００以外の構成についても、実施の形態１に係る照明装置１００の構成と同じである。 In the present embodiment, the configuration of the container 370 of the power supply unit 300 is different from the configuration of the container 370 of the power supply unit 300 in the first embodiment. Other configurations of power supply unit 300 are the same as those of power supply unit 300 in the first embodiment. The configuration of lighting apparatus 100 other than power supply unit 300 is the same as that of lighting apparatus 100 according to Embodiment 1.
　図５０及び図５１及び図５２を参照して、収容体３７０の構成を説明する。 The configuration of the container 370 will be described with reference to FIG. 50, FIG. 51, and FIG.
　本実施の形態では、第２収容部３７２の底壁に設けられた貫通孔３７４が、第２収容部３７２の内側から第２収容部３７２の外側に向かって徐々に狭くなっている。即ち、柱部３７５に設けられた貫通孔３７４の縦断面は、柱部３７５の先端に向かって先細りの錘状になっている。換言すると、貫通孔３７４の横断面は、柱部３７５の第２収容部３７２に近い側より先端部側の方が、開口面積が小さくなっている。これにより、出力電線３２０を貫通孔３７４に挿通しやすくなる。 In the present embodiment, the through hole 374 provided in the bottom wall of the second housing portion 372 is gradually narrowed from the inside of the second housing portion 372 toward the outside of the second housing portion 372. That is, the vertical cross section of the through hole 374 provided in the column part 375 has a tapered weight shape toward the tip of the column part 375. In other words, the cross-sectional area of the through hole 374 has a smaller opening area on the distal end side than on the side closer to the second accommodating portion 372 of the column portion 375. Thereby, it becomes easy to insert the output electric wire 320 into the through hole 374.
　出力電線３２０が接触する柱部３７５の先端部には、Ｒ面加工、Ｃ面加工等のエッジ処理が施されることが望ましい。 It is desirable that edge processing such as R surface processing and C surface processing is performed on the tip of the column portion 375 with which the output electric wire 320 contacts.
　なお、柱部３７５に設けられた貫通孔３７４の横断面の形状、即ち、貫通孔３７４の開口形状は、矩形等の多角形でもよいし、真円形、楕円形、長円形等の円形でもよいし、星形等、その他の形状でもよい。同様に、柱部３７５の横断面の外形は、矩形等の多角形でもよいし、真円形、楕円形、長円形等の円形でもよいし、星形等、その他の形状でもよい。 The cross-sectional shape of the through hole 374 provided in the column portion 375, that is, the opening shape of the through hole 374 may be a polygon such as a rectangle, or a circle such as a true circle, an ellipse, or an oval. However, other shapes such as a star shape may be used. Similarly, the outer shape of the cross section of the column portion 375 may be a polygon such as a rectangle, a circle such as a true circle, an ellipse, or an oval, or another shape such as a star.
　本実施の形態では、実施の形態１と同じように、柱部３７５の凹部３８６が２箇所に設けられるが、凹部３８６は、１箇所のみ、具体的には片側のみに設けられてもよいし、３箇所以上に設けられてもよい。特に、出力電線３２０の配線経路が１方向である場合、又は、出力電線３２０の複数の配線経路が近い場合には、凹部３８６は、１箇所に設けられていればよい。 In the present embodiment, as in the first embodiment, the recesses 386 of the column part 375 are provided in two places, but the recesses 386 may be provided only in one place, specifically, only on one side. You may provide in three or more places. In particular, when the wiring path of the output electric wire 320 is in one direction, or when a plurality of wiring paths of the output electric wire 320 are close to each other, the recess 386 may be provided at one place.
　凹部３８６は、出力電線３２０の張力止めを兼ねてもよい。その場合、凹部３８６の幅は、出力電線３２０の被覆を含む外径よりやや狭いものとする。凹部３８６が出力電線３２０を挟んで保持することで、出力電線３２０に振動又は衝撃が加わっても、出力電線３２０が凹部３８６と擦れてダメージを受けることがなく、また、光源基板２１０のコネクタ２１２の接続不良等も防ぐことができる。 The recess 386 may also serve as a tension stopper for the output electric wire 320. In that case, the width of the recess 386 is slightly narrower than the outer diameter including the covering of the output electric wire 320. The concave portion 386 holds the output electric wire 320 with the output electric wire 320 interposed therebetween, so that even if vibration or impact is applied to the output electric wire 320, the output electric wire 320 is not rubbed and damaged by the concave portion 386. It is possible to prevent poor connection.
　本実施の形態では、実施の形態１と同じように、柱部３７５が１箇所のみに設けられるが、柱部３７５は、出力電線３２０が電気接続される対象の数及び配置、具体的にはコネクタ２１２の数及び配置に応じて、２箇所以上に設けられてもよい。 In the present embodiment, as in the first embodiment, the column portion 375 is provided only in one place. However, the column portion 375 has the number and arrangement of objects to which the output electric wire 320 is electrically connected, specifically, Two or more locations may be provided depending on the number and arrangement of the connectors 212.
　柱部３７５は、筐体３３０の貫通孔３３３に圧入されてもよい。その場合、収容体３７０を、筐体３３０から外れないように固定することができ、ネジ止めが不要となる。 The column part 375 may be press-fitted into the through hole 333 of the housing 330. In that case, the container 370 can be fixed so as not to be detached from the housing 330, and screwing is unnecessary.
　柱部３７５は、ロック機構を備えてもよい。具体的には、柱部３７５は、筐体３３０の貫通孔３３３に柱部３７５が挿通されている状態で貫通孔３３３の周縁部に引っ掛かる突起を有していてもよい。その場合も、収容体３７０を、筐体３３０から外れないように固定することができ、ネジ止めが不要となる。 The column part 375 may include a lock mechanism. Specifically, the pillar portion 375 may have a protrusion that is caught by the peripheral edge portion of the through hole 333 in a state where the pillar portion 375 is inserted into the through hole 333 of the housing 330. Also in this case, the container 370 can be fixed so as not to be detached from the housing 330, and screwing is not necessary.
　柱部３７５は、第２収容部３７２とは別体の筒型のリベットとして構成されてもよい。その場合、柱部３７５となるリベットは、出力電線３２０が挿通されている状態で、第２収容部３７２の底壁に設けられた貫通孔３７４に圧入され、第２収容部３７２の底壁に固定される。柱部３７５となるリベットは、出力電線３２０の張力止めを兼ねてもよい。また、柱部３７５となるリベットは、収容体３７０の底壁と筐体３３０の底壁部３３２とを固定する機能を兼ねてもよい。その場合、収容体３７０を、筐体３３０から外れないように固定することができ、ネジ止めが不要となる。 The column part 375 may be configured as a cylindrical rivet separate from the second storage part 372. In that case, the rivet that becomes the column portion 375 is press-fitted into a through hole 374 provided in the bottom wall of the second housing portion 372 in a state where the output electric wire 320 is inserted, and is inserted into the bottom wall of the second housing portion 372. Fixed. The rivet that becomes the column portion 375 may also serve as a tension stopper for the output electric wire 320. In addition, the rivet that becomes the column portion 375 may also have a function of fixing the bottom wall of the container 370 and the bottom wall portion 332 of the housing 330. In that case, the container 370 can be fixed so as not to be detached from the housing 330, and screwing is unnecessary.
　実施の形態１では、第２収容部３７２が外周方向に開放されている。このため、収容体３７０の外側から貫通孔３７４を目視しやすく、出力電線３２０を貫通孔３７４に挿通させやすい。これに対して、本実施の形態では、第２収容部３７２が、第１収容部３７１と同じように外周方向に閉鎖されている。このため、収容体３７０の剛性が増し、照明装置１００の構造強度を高めることができる。また、出力電線３２０を、放熱機能を発揮する筐体３３０と離すことによって保護することができる。出力電線３２０が収容体３７０と筐体３３０との間に挟まれるおそれもなくなり、出力電線３２０の被覆が傷つけられて出力電線３２０が短絡することを防止できる。さらに、収容体３７０が出力電線３２０と筐体３３０との間に介在することによって、絶縁性能が向上する。特に、筐体３３０が金属材料で形成され、照明装置１００の外部から高い電圧の外来ノイズを受けた場合に、外来ノイズが出力電線３２０に伝搬して、発光素子２１１及び点灯回路３１１にダメージを与えることを防止できる。 In Embodiment 1, the 2nd accommodating part 372 is open | released in the outer peripheral direction. For this reason, it is easy to visually check the through-hole 374 from the outside of the container 370, and the output electric wire 320 is easily inserted into the through-hole 374. On the other hand, in this Embodiment, the 2nd accommodating part 372 is closed in the outer peripheral direction like the 1st accommodating part 371. For this reason, the rigidity of the container 370 can be increased and the structural strength of the lighting device 100 can be increased. Further, the output electric wire 320 can be protected by being separated from the housing 330 that exhibits a heat dissipation function. There is no possibility that the output electric wire 320 is sandwiched between the container 370 and the housing 330, and it is possible to prevent the output electric wire 320 from being short-circuited due to the covering of the output electric wire 320 being damaged. Furthermore, the insulation performance is improved by interposing the container 370 between the output electric wire 320 and the housing 330. In particular, when the housing 330 is formed of a metal material and receives high voltage external noise from the outside of the lighting device 100, the external noise propagates to the output electric wire 320 and damages the light emitting element 211 and the lighting circuit 311. It can prevent giving.
　また、本実施の形態では、第２収容部３７２の内壁面８０６が傾斜することで第２収容部３７２の内部空間が第２収容部３７２の底壁に設けられた貫通孔３７４に向かって徐々に狭くなっている。即ち、第２収容部３７２は、内壁面８０６が貫通孔３７４に向かって漏斗状に傾斜している。このため、貫通孔３７４が収容体３７０の外側から目視できなくても、出力電線３２０を貫通孔３７４にスムーズに挿通させることができる。 In the present embodiment, the inner wall surface 806 of the second housing portion 372 is inclined, so that the internal space of the second housing portion 372 gradually moves toward the through hole 374 provided in the bottom wall of the second housing portion 372. It has become narrower. In other words, the inner wall surface 806 of the second housing portion 372 is inclined in a funnel shape toward the through hole 374. For this reason, even if the through hole 374 is not visible from the outside of the container 370, the output electric wire 320 can be smoothly inserted into the through hole 374.
　以上、本発明の実施の形態について説明したが、これらの実施の形態のうち、いくつかを組み合わせて実施しても構わない。或いは、これらの実施の形態のうち、いずれか１つ又はいくつかを部分的に実施しても構わない。例えば、これらの実施の形態の説明において「部」として説明するもののうち、いずれか１つのみを採用してもよいし、いくつかの任意の組み合わせを採用してもよい。なお、本発明は、これらの実施の形態に限定されるものではなく、必要に応じて種々の変更が可能である。 As mentioned above, although embodiment of this invention was described, you may implement combining some of these embodiment.
