照明器具１００は、例えば、取付面２００の一例としての天井面に取り付けられる照明器具１００であって、二次電池１０を搭載し、通常時には点灯装置２０が商用電源等の外部電源からの電力で二次電池１０を充電し、商用電源の停電等の非常時には、点灯装置２０が充電した二次電池１０の電力で光源を点灯させる非常用照明器具である。 The luminaire 100 is, for example, a luminaire 100 that is attached to a ceiling surface as an example of the attachment surface 200. The luminaire 100 is equipped with a secondary battery 10, and normally the lighting device 20 is powered by an external power source such as a commercial power source. This is an emergency lighting device that charges the secondary battery 10 and lights the light source with the power of the secondary battery 10 charged by the lighting device 20 in the event of an emergency such as a power failure of the commercial power supply.

図２〜図７を用いて、本実施の形態に係る照明器具１００の構成について説明する。 The structure of the lighting fixture 100 which concerns on this Embodiment is demonstrated using FIGS.

点灯装置２０は、ユニットケース５０を備えており、ユニットケース５０に点灯装置２０を構成する部品等を装着している。 The lighting device 20 includes a unit case 50, and components and the like constituting the lighting device 20 are mounted on the unit case 50.

ユニットケース５０は、点灯回路基板３０と電源端子台６０とＬＥＤ７０（光源の一例）とＬＥＤ７０を覆うレンズ７１と二次電池１０とを各々装着する複数の装着部と、本体に取り付けるための爪部（本体取付部５４）とを有している。 The unit case 50 includes a lighting circuit board 30, a power terminal block 60, an LED 70 (an example of a light source), a plurality of mounting portions for mounting the lens 71 covering the LED 70, and the secondary battery 10, and a claw portion for mounting on the main body. (Main body attachment portion 54).

すなわち、実施の形態１に係る照明器具１００は、ユニットケース５０に点灯装置２０を構成する部品等（点灯回路基板３０と電源端子台６０とＬＥＤ７０（光源の一例）とＬＥＤ７０を覆うレンズ７１）を各々に対応する複数の装着部によって一体に装着し、点灯装置２０を構成する部品等を一体に装着したユニットケース５０を本体取付部５４によって本体４０に取り付け、点灯装置２０と本体４０とが一体化した状態のままで、取付面２００に取り付けることができる照明器具１００である。さらに、実施の形態１に係る照明器具１００は、点灯装置２０と一体化した本体４０を取付面２００に取り付けた後、二次電池１０とカバー８０とを容易に取り付けることができる各々の装着部をも備えている。 That is, the luminaire 100 according to the first embodiment includes components (such as the lighting circuit board 30, the power supply terminal block 60, the LED 70 (an example of the light source), and the lens 71 that covers the LED 70) included in the lighting device 20 in the unit case 50. A unit case 50, which is integrally mounted by a plurality of mounting portions corresponding to each of them, and integrally mounted with components and the like constituting the lighting device 20, is mounted to the main body 40 by the main body mounting portion 54, and the lighting device 20 and the main body 40 are integrated. It is the lighting fixture 100 which can be attached to the attachment surface 200 in the state which was converted into. Furthermore, the luminaire 100 according to the first embodiment has each mounting portion that can easily attach the secondary battery 10 and the cover 80 after the main body 40 integrated with the lighting device 20 is attached to the attachment surface 200. Is also provided.

以下に、点灯装置２０を構成する部品等（点灯回路基板３０と電源端子台６０とＬＥＤ７０（光源の一例）とＬＥＤ７０を覆うレンズ７１）と二次電池１０とカバー８０とを、ユニットケース５０に装着するための複数の装着部について説明する。 Hereinafter, the components constituting the lighting device 20 (the lighting circuit board 30, the power terminal block 60, the LED 70 (an example of the light source), the lens 71 covering the LED 70), the secondary battery 10, and the cover 80 are provided in the unit case 50. A plurality of mounting portions for mounting will be described.

＜光源取付部５２＞
ユニットケース５０は、取付面２００側が開口している筒状であって、取付面２００側とは反対側の面であるケース光源面５１の略中心部にＬＥＤ７０とレンズ７１とを取り付けるための光源取付部５２（装着部の一例）を備えている。 <Light source mounting part 52>
The unit case 50 has a cylindrical shape with an opening on the attachment surface 200 side, and a light source for attaching the LED 70 and the lens 71 to the substantially central portion of the case light source surface 51 that is the surface opposite to the attachment surface 200 side. A mounting portion 52 (an example of a mounting portion) is provided.

ユニットケース５０には、光源取付部５２からケース光源面５１の周縁部に向かって所定の幅で開口するケース切り欠き部５５が形成されている。さらに、ユニットケース５０には、ケース切り欠き部５５の開口の入り口部分であってケース光源面５１の周縁部の端部５５ａ，５５ｂ（図３参照）から、端部５５ａから端部５５ｂまでの距離の幅で、垂直上方（ケース光源面５１から取付面２００方向）に、ユニットケース５０の側面を縦に開口した側面開口部５３５が形成されている。側面における側面開口部５３５の開口の両側の縁部（縁辺部）は、略平行となっている。側面開口部５３５は、端部５５ａから端部５５ｂまでの距離の幅で、ケース光源面５１から取付面２００側の開口までのユニットケース５０の側面をすべて開口してもよい。ケース光源面５１の平面形状は、馬蹄形、Ｕ字状、コ字状となり、後述する二次電池１０の平面形状と略同一となる。 The unit case 50 is formed with a case notch 55 that opens from the light source mounting portion 52 toward the peripheral edge of the case light source surface 51 with a predetermined width. Further, the unit case 50 has an entrance portion of the opening of the case cutout portion 55 and from the end portions 55a and 55b (see FIG. 3) of the peripheral portion of the case light source surface 51 to the end portions 55a to 55b. A side opening 535 that vertically opens the side surface of the unit case 50 is formed vertically upward (in the direction of the mounting surface 200 from the case light source surface 51) with the width of the distance. Edge portions (edge portions) on both sides of the opening of the side surface opening 535 on the side surface are substantially parallel. The side opening 535 may have a width of a distance from the end 55a to the end 55b, and may open all sides of the unit case 50 from the case light source surface 51 to the opening on the mounting surface 200 side. The planar shape of the case light source surface 51 is horseshoe-shaped, U-shaped, or U-shaped, and is substantially the same as the planar shape of the secondary battery 10 described later.

また、所定の位置まで開口し、ユニットケース５０の側面の上部は開口していなくてもよい。この場合、ユニットケース５０は、円筒形になる。 Moreover, it opens to a predetermined position and the upper part of the side surface of the unit case 50 does not need to open. In this case, the unit case 50 has a cylindrical shape.

ケース切り欠き部５５には、後述する電源端子台６０を挿入して配置するため、作業性を考慮して、ケース切り欠き部５５の幅は電源端子台６０の長手方向の幅よりもやや広くして、ケース切り欠き部５５の両縁部と電源端子台６０との間に隙間を設けることが望ましい。ただし、照明器具のコンパクト化を考慮すると、上記隙間はできるだけせまい方が好ましい。 Since the power supply terminal block 60 to be described later is inserted and disposed in the case cutout portion 55, the width of the case cutout portion 55 is slightly wider than the width in the longitudinal direction of the power supply terminal block 60 in consideration of workability. Thus, it is desirable to provide a gap between both edges of the case notch 55 and the power terminal block 60. However, in consideration of downsizing of the luminaire, the gap is preferably as narrow as possible.

また、ユニットケース５０は、点灯装置２０を構成する部品等を複数の装着部によって一体に装着した後、本体取付部５４によって本体４０に取り付けられた状態のままで、本体４０の器具取付穴４２からネジを通して取付面２００にネジ止めすることができるように、ねじ回し具等を挿入するためのケース孔５０１をケース光源面５１に設けている。したがって、ケース孔５０１は、ユニットケース５０を本体４０に取り付けた状態で、器具取付穴４２ａと器具取付穴４２ｂとに対応する位置（器具取付穴４２ａ，４２ｂの垂直軸とケース光源面５１との交点）に設けられる。 In addition, the unit case 50 is mounted on the main body 40 by the main body mounting portion 54 after the components constituting the lighting device 20 are integrally mounted by a plurality of mounting portions, and then the instrument mounting hole 42 of the main body 40. A case hole 501 for inserting a screwdriver or the like is provided in the case light source surface 51 so that the screw can be screwed to the mounting surface 200 through a screw. Accordingly, the case hole 501 is located at a position corresponding to the instrument mounting hole 42a and the instrument mounting hole 42b (the vertical axis of the instrument mounting holes 42a and 42b and the case light source surface 51 between the unit mounting case 50 and the main body 40). At the intersection).

ＬＥＤ７０は、ＬＥＤ基台７０１に設置され、点灯回路基板３０に接続するためのＬＥＤ接続線７０２とＬＥＤ接続端子７０３とを備えている。レンズ７１は、底部にＬＥＤを配置するための開口を形成したお椀型のレンズである。レンズ７１は、ＬＥＤ７０を配置した底部から、底部とは反対側の開口部の周縁部（レンズ縁部７１１）にわたっての側面に、ＬＥＤ７０の光を反射させるための反射体を備えていてもよい。 The LED 70 is installed on the LED base 701 and includes an LED connection line 702 and an LED connection terminal 703 for connecting to the lighting circuit board 30. The lens 71 is a bowl-shaped lens in which an opening for arranging an LED is formed at the bottom. The lens 71 may include a reflector for reflecting the light of the LED 70 on the side surface extending from the bottom where the LED 70 is disposed to the peripheral edge (lens edge 711) of the opening opposite to the bottom.

光源取付部５２は、ケース光源面５１の略中心部に筒状に突出して形成され、ケース光源面５１側の反対側の面は、ＬＥＤ７０を挿入するために開口している。したがって、光源取付部５２の内径は、作業性を考慮して、ＬＥＤ基台７０１の径よりもやや大きい内径となっているのがよい。光源取付部５２の開口の周縁部には、少なくとも２カ所に内側に突出した爪部５２１を設けている（図３参照）。さらに、光源取付部５２の側面のケース切り欠き部５５側には、光源取付部５２の側面を縦に開口するスリット部５２２を設けている（図３参照）。 The light source mounting portion 52 is formed to project in a substantially central portion of the case light source surface 51 in a cylindrical shape, and the surface on the opposite side to the case light source surface 51 side is opened to insert the LED 70. Therefore, it is preferable that the inner diameter of the light source mounting portion 52 is slightly larger than the diameter of the LED base 701 in consideration of workability. On the peripheral edge of the opening of the light source mounting portion 52, at least two claw portions 521 protruding inward are provided (see FIG. 3). Further, a slit portion 522 that vertically opens the side surface of the light source attachment portion 52 is provided on the side of the case cutout portion 55 on the side surface of the light source attachment portion 52 (see FIG. 3).

ＬＥＤ７０を光源取付部５２に取り付ける（すなわち、ユニットケース５０に装着する）場合は、まず、ＬＥＤ７０を設置したＬＥＤ基台７０１を筒状の光源取付部５２の開口から挿入し、ＬＥＤ接続線７０２をスリット部５２２に通して光源取付部５２の外側に引き出し、ＬＥＤ接続線７０２の端部のＬＥＤ接続端子７０３はケース切り欠き部５５を通して後述する点灯回路基板３０に接続する。図４に示すように、レンズ７１は、ＬＥＤ７０がレンズ７１の底部に配置されるようにレンズ７１の底部から光源取付部５２の開口に挿入して、レンズ７１の底部でＬＥＤ基台７０１を押し付けるように密着させて押し込み、レンズ縁部７１１を光源取付部５２の爪部５２１に引っ掛けることによりレンズ７１を光源取付部５２の内部に係止する。 When the LED 70 is attached to the light source attachment portion 52 (that is, attached to the unit case 50), first, the LED base 701 on which the LED 70 is installed is inserted from the opening of the cylindrical light source attachment portion 52, and the LED connection line 702 is connected. The LED connection terminal 703 at the end of the LED connection line 702 is connected to the lighting circuit board 30 described later through the case notch 55 through the slit portion 522 and pulled out to the outside of the light source mounting portion 52. As shown in FIG. 4, the lens 71 is inserted into the opening of the light source mounting portion 52 from the bottom of the lens 71 so that the LED 70 is disposed at the bottom of the lens 71, and presses the LED base 701 at the bottom of the lens 71. The lens 71 is locked inside the light source mounting portion 52 by pushing the lens edge portion 711 into contact with the claw portion 521 of the light source mounting portion 52.

＜電池収容部５３＞
ユニットケース５０は、二次電池１０の片面をケース光源面５１に当接させて収容する電池収容部５３（装着部の一例）を備えている。図２、図３を用いて電池収容部５３について詳しく説明する。 <Battery accommodating portion 53>
The unit case 50 includes a battery housing portion 53 (an example of a mounting portion) that houses one side of the secondary battery 10 in contact with the case light source surface 51. The battery accommodating portion 53 will be described in detail with reference to FIGS.

電池収容部５３は、二次電池１０を収容したときに二次電池１０の周囲の側面（側壁１２）の一部を覆う側壁部５３２と二次電池１０の下面の周縁部の一部を支えて係止するための電池係止部５３１とから構成される。側壁部５３２は、ユニットケース５０の側面の一部をケース光源面方向に延設して形成される。側壁部５３２の下端部には、側壁部５３２の下端部を内側に略直角に折り曲げて、折り曲げた内面に二次電池１０の下面の周縁部を載置して支えることにより二次電池１０を係止する電池係止部５３１が形成される。電池収容部５３は、ユニットケース５０の周縁部であってケース切り欠き部５５の両側の端部５５ａ，５５ｂ（ケース切り欠き部５５の開口の入り口の両側の端部）から、ユニットケース５０の周縁部に沿って両側に略対称に形成される。両側の電池収容部５３の側壁部５３２の側壁終端部（５３２ａ、５３２ｂ）は、５３２ａと５３２ｂとを結ぶ線が、ケース光源面５１の略２等分する位置となり、電池収容部５３の電池挿入口５３４となる。 The battery housing part 53 supports a side wall part 532 that covers a part of the side surface (side wall 12) around the secondary battery 10 when the secondary battery 10 is housed, and a part of the peripheral edge part of the lower surface of the secondary battery 10. And a battery locking portion 531 for locking. The side wall portion 532 is formed by extending a part of the side surface of the unit case 50 in the case light source surface direction. The lower end portion of the side wall portion 532 is bent at a substantially right angle at the lower end portion of the side wall portion 532, and the peripheral portion of the lower surface of the secondary battery 10 is placed on the bent inner surface to support the secondary battery 10. A battery locking portion 531 to be locked is formed. The battery housing portion 53 is a peripheral portion of the unit case 50, and from end portions 55 a and 55 b on both sides of the case cutout portion 55 (end portions on both sides of the entrance of the opening of the case cutout portion 55). It is formed substantially symmetrically on both sides along the peripheral edge. Side wall terminal portions (532 a, 532 b) of the side wall portions 532 of the battery housing portions 53 on both sides are positioned so that the line connecting 532 a and 532 b is divided into approximately two equal parts of the case light source surface 51. It becomes the mouth 534.

ここで、二次電池１０の形状について説明する。二次電池１０は、平板状であって、片側に所定の幅で開口する電池開口部１１を形成した馬蹄形（Ｕ字状、コ字状）である。例えば、ドーナツ形（環状形）の一部を欠いた形状である。二次電池１０の電池開口部１１の全面を塞いだと仮定した場合の二次電池１０の形状は、ドーナツ状、円状、輪状、環状になり、その外形は、ケース光源面５１と略同一の形状であることが好ましい。したがって、二次電池１０の形状は、ケース光源面５１と略同一形状であって片側に所定の幅で開口する電池開口部１１を形成した形状であるといえる。 Here, the shape of the secondary battery 10 will be described. The secondary battery 10 has a flat plate shape, and has a horseshoe shape (U-shape or U-shape) in which a battery opening portion 11 having a predetermined width is formed on one side. For example, it is a shape lacking a part of a donut shape (annular shape). Assuming that the entire surface of the battery opening 11 of the secondary battery 10 is closed, the shape of the secondary battery 10 is a donut shape, a circular shape, a ring shape, and an annular shape, and the outer shape is substantially the same as the case light source surface 51. It is preferable that it is the shape of this. Therefore, it can be said that the shape of the secondary battery 10 is substantially the same shape as that of the case light source surface 51 and the battery opening 11 having an opening with a predetermined width is formed on one side.

電池開口部１１は、二次電池１０の略中心部に所定の径の長さで開口する中心開口部１３（電池開口部１１の終端部）を形成し、中心開口部１３から連結して片側に所定の幅で開口している。二次電池１０が電池収容部５３に収容された場合には、中心開口部１３には光源取付部５２が収まるので、中心開口部１３の径は作業性を考慮して光源取付部５２の径よりやや大きいことが望ましい。また、二次電池１０が電池収容部５３に収容された場合には、電池開口部１１とユニットケース５０のケース切り欠き部５５とが略重なって、開口を形成し、その開口には、後述する電源端子台６０が挿入されて配置される。そのため、電池開口部１１の幅は、ケース切り欠き部の幅と略同一であることが好ましい。電池開口部１１の幅も上述したケース切り欠き部５５の幅と同様に、電源端子台６０を挿入するため、作業性を考慮して、電源端子台６０の長手方向の幅よりもやや広くして、電池開口部１１の両縁部と電源端子台６０との間に隙間を設けることが望ましい。ただし、照明器具のコンパクト化を考慮すると、上記隙間はできるだけ短い方が好適である。 The battery opening 11 forms a central opening 13 (a terminal portion of the battery opening 11) that opens at a predetermined diameter at a substantially central portion of the secondary battery 10, and is connected to the central opening 13 on one side. Are opened with a predetermined width. When the secondary battery 10 is accommodated in the battery accommodating portion 53, the light source attachment portion 52 is accommodated in the central opening portion 13. Therefore, the diameter of the central opening portion 13 is the diameter of the light source attachment portion 52 in consideration of workability. A slightly larger size is desirable. Further, when the secondary battery 10 is accommodated in the battery accommodating portion 53, the battery opening 11 and the case cutout portion 55 of the unit case 50 are substantially overlapped to form an opening. The power terminal block 60 is inserted and arranged. Therefore, it is preferable that the width of the battery opening 11 is substantially the same as the width of the case notch. Similarly to the width of the case notch 55 described above, the width of the battery opening 11 is slightly wider than the width in the longitudinal direction of the power terminal block 60 in consideration of workability because the power terminal block 60 is inserted. Thus, it is desirable to provide a gap between the both edges of the battery opening 11 and the power terminal block 60. However, considering the compactness of the lighting fixture, it is preferable that the gap is as short as possible.

二次電池１０を電池収容部５３に収容する（すなわち、ユニットケース５０に装着する）場合は、二次電池１０の電池開口部１１に光源取付部５２を嵌めるようにしながら二次電池１０の片面をケース光源面５１に当接させつつ、二次電池１０を電池挿入部５３４から挿入してケース切り欠き部５５の方向へスライドさせて収容する。中心開口部１３（電池開口部１１の終端部１２）に光源取付部５２が位置するまで二次電池１０をスライドさせて収容する。 When the secondary battery 10 is accommodated in the battery accommodating portion 53 (that is, attached to the unit case 50), one side of the secondary battery 10 is placed while the light source attachment portion 52 is fitted in the battery opening 11 of the secondary battery 10. The secondary battery 10 is inserted from the battery insertion portion 534 and slid in the direction of the case cutout portion 55 while being in contact with the case light source surface 51. The secondary battery 10 is slid and accommodated until the light source mounting portion 52 is positioned at the central opening 13 (the terminal end 12 of the battery opening 11).

このとき、二次電池１０の高さＭと光源取付部５２の高さＮは、略等しい（Ｍ≒Ｎ）。また、電池収容部５３の側壁部５３２の高さＬは、二次電池の高さＭと略等しいことが好ましいが、作業性を考慮すると、側壁部５３２の長さＬを二次電池の高さＭよりやや長くしてケース光源面５１と当接する二次電池１０の面とにクリアランス（隙間）があった方が好ましい（Ｌ≧Ｍ）。ただし、照明器具の高さＨの低減化を考慮すると、ケース光源面５１と当接する二次電池１０の面とのクリアランスはできるだけ小さくするのが好適である（Ｌ−Ｍ≒０）。 At this time, the height M of the secondary battery 10 and the height N of the light source mounting portion 52 are substantially equal (M≈N). Moreover, it is preferable that the height L of the side wall portion 532 of the battery housing portion 53 is substantially equal to the height M of the secondary battery. However, in consideration of workability, the length L of the side wall portion 532 is set to the height of the secondary battery. It is preferable that there is a clearance (gap) between the surface of the secondary battery 10 that is slightly longer than the length M and is in contact with the case light source surface 51 (L ≧ M). However, in consideration of a reduction in the height H of the lighting fixture, it is preferable to make the clearance between the case light source surface 51 and the surface of the secondary battery 10 in contact as small as possible (LM = 0).

The substrate hole 32 is provided. The positions of the board holes 32 are the positions corresponding to the instrument mounting holes 42a and the instrument mounting holes 42b in a state in which the unit case 50 with the lighting circuit board 30 mounted is attached to the main body 40, similarly to the position of the case holes 501 ( It is provided at a position where the vertical axis of the fixture mounting holes 42a and 42b intersects the lighting circuit board 30). That is, the operator works by inserting a screwdriver or the like from the case hole 501 of the unit case 50, passing through the board hole 32, and reaching the instrument mounting hole 42 of the main body 40. be able to.

次に、図５及び図７を用いて、基板装着部５８（装着部の一例）について説明する。ユニットケース５０の内側面には少なくとも２カ所以上に基板装着部５８を備えている。基板装着部５８は、基板爪部５８ａと基板係止台５８ｂとから構成されている。 Next, the substrate mounting portion 58 (an example of a mounting portion) will be described with reference to FIGS. At least two or more board mounting portions 58 are provided on the inner surface of the unit case 50. The board mounting portion 58 includes a board claw portion 58a and a board locking base 58b.

図７（ａ）は、図５のＣ−Ｄ断面をＦからＥの方向に見た図である。図７（ｂ）は、ユニットケース５０のＥ−Ｆ間付近を上から（取付面２００側から）見た図である。図７（ｃ）は、ユニットケース５０のＥ−Ｆ間付近の部分斜視図である。基板係止台５８ｂは、図７（ａ）〜（ｃ）に示すように、ユニットケース５０の内側面に板状に突出している。また、基板爪部５８ａは、図７（ａ）〜（ｃ）に示すように、ユニットケース５０の内側面の基板係止台５８ｂより上側の位置に爪状（断面が略直角三角形状）に突出して設けられている。ユニットケース５０を上から見た場合（図７（ｂ）参照）、基板爪部５８ａと基板係止台５８ｂの円周方向（Ｅ−Ｆ方向）の位置関係は、作業性を考慮すると、所定の距離（図７（ｂ）の距離Ｋ）ずれた位置関係にある方が好ましい。 FIG. 7A is a view of the CD cross section of FIG. 5 as viewed from F to E. FIG. FIG. 7B is a view of the vicinity of EF of the unit case 50 as viewed from above (from the mounting surface 200 side). FIG. 7C is a partial perspective view of the unit case 50 in the vicinity of EF. As shown in FIGS. 7A to 7C, the board locking table 58 b protrudes in a plate shape on the inner side surface of the unit case 50. Further, as shown in FIGS. 7A to 7C, the board claw portion 58a has a claw shape (a cross section is substantially a right triangle) at a position above the board locking base 58b on the inner side surface of the unit case 50. Protrusively provided. When the unit case 50 is viewed from above (see FIG. 7B), the positional relationship in the circumferential direction (EF direction) between the substrate claw portion 58a and the substrate locking base 58b is predetermined in consideration of workability. It is preferable that the positional relationship is shifted by a distance (distance K in FIG. 7B).

図７（ａ）に示すように、基板係止台５８ｂの上面５８１と基板爪部５８ａの底面部５８３の間の隙間Ｉは、点灯回路基板３０を嵌めるための基板嵌合部５９となっている。また、点灯回路基板３０を基板装着部５８に嵌めるときの作業性を考えて、基板爪部５８ａにはテーパー５８２を設けている。 As shown in FIG. 7A, the gap I between the upper surface 581 of the substrate locking base 58b and the bottom surface portion 583 of the substrate claw portion 58a becomes a substrate fitting portion 59 for fitting the lighting circuit substrate 30. Yes. In consideration of workability when the lighting circuit board 30 is fitted to the board mounting portion 58, the board claw portion 58a is provided with a taper 582.

点灯回路基板３０をユニットケース５０に取り付ける場合は、ユニットケース５０の上部（取付面２００側）の開口から、点灯回路基板３０を、ケース光源面５１に略平行で、基板開口部３３がケース切り欠き部５５及び電池開口部１１に略重なる位置になるように挿入して、点灯回路基板３０を押し込むことにより、点灯回路基板３０がユニットケース５０の基板係止台５８ｂの上面５８１と基板爪部５８ａの底面部５８３の間の基板嵌合部５９に嵌められる。このとき、図５に示すように、点灯回路基板３０の側壁部の基板爪部５８ａに対応する部分に基板溝部３１を設けておくと、点灯回路基板３０を基板装着部５８に嵌めやすい。また、基板溝部３１を設けておくことで、点灯回路基板３０の装着時の位置決めにも利用することができる。ただし、基板溝部３１の奥行きの距離（長さ）は、基板爪部５８ａの底面部５８３の突出長（ユニットケース５０の側面から突出している距離）よりも短くする必要がある。また、基板溝部３１はなくても構わない。 When attaching the lighting circuit board 30 to the unit case 50, the lighting circuit board 30 is substantially parallel to the case light source surface 51 through the opening on the upper side (attachment surface 200 side) of the unit case 50, and the board opening 33 is cut into the case. The lighting circuit board 30 is inserted into the notch 55 and the battery opening 11 so as to substantially overlap, and the lighting circuit board 30 is pushed in, whereby the lighting circuit board 30 is connected to the upper surface 581 of the board locking base 58b of the unit case 50 and the board claw part. It fits in the board | substrate fitting part 59 between the bottom face parts 583 of 58a. At this time, as shown in FIG. 5, if the substrate groove portion 31 is provided in a portion corresponding to the substrate claw portion 58 a of the side wall portion of the lighting circuit substrate 30, the lighting circuit substrate 30 can be easily fitted into the substrate mounting portion 58. Further, by providing the substrate groove 31, it can be used for positioning when the lighting circuit substrate 30 is mounted. However, the depth distance (length) of the substrate groove portion 31 needs to be shorter than the protruding length of the bottom surface portion 583 of the substrate claw portion 58a (the distance protruding from the side surface of the unit case 50). The substrate groove 31 may not be provided.

以下に、基板装着部５８の他の例について説明する。例えば、点灯回路基板３０の側壁面に、少なくとも２カ所以上に、ユニットケース５０に装着するための爪を設ける。基板装着部５８は、例えば、ユニットケース５０の内側面に設けられた溝部であり、点灯回路基板３０をケース光源面５１に対して略平行で、基板開口部３３がケース切り欠き部５５及び電池開口部１１に略重なる位置になるように装着した場合に、複数の上記爪と対応する場所に設けられる。ユニットケース５０の上部（取付面２００側）の開口から、点灯回路基板３０を、ケース光源面５１に略平行で、基板開口部３３がケース切り欠き部５５及び電池開口部１１に略重なる位置になるように挿入して、点灯回路基板３０を押し込むことにより、点灯回路基板３０の上記爪がユニットケース５０の基板装着部５８の溝に嵌って、点灯回路基板３０がユニットケース５０に装着される。 Below, the other example of the board | substrate mounting part 58 is demonstrated. For example, a claw for attaching to the unit case 50 is provided on at least two places on the side wall surface of the lighting circuit board 30. The board mounting portion 58 is, for example, a groove provided on the inner side surface of the unit case 50, the lighting circuit board 30 is substantially parallel to the case light source surface 51, and the board opening 33 is the case notch 55 and the battery. When mounted so as to be substantially overlapped with the opening 11, it is provided at a location corresponding to the plurality of claws. From the opening on the upper side (mounting surface 200 side) of the unit case 50, the lighting circuit board 30 is substantially parallel to the case light source surface 51, and the board opening 33 substantially overlaps the case notch 55 and the battery opening 11. When the lighting circuit board 30 is pushed in, the claw of the lighting circuit board 30 fits into the groove of the board mounting portion 58 of the unit case 50, and the lighting circuit board 30 is mounted on the unit case 50. .

The power terminal block 60 includes a power terminal 62 connected to an external power source such as a commercial power source. Since the power terminal block 60 is installed on the unit case 50 by screws, a power terminal block mounting bracket 61 having holes 64a and 64b through which screws are passed is attached.

ユニットケース５０は、電源端子台６０をネジ止めして係止するための端子台係止部５６ａ，５６ｂ（装着部の一例）を備えている。端子台係止部５６は、ネジを通す孔である。 The unit case 50 includes terminal block locking portions 56a and 56b (an example of a mounting portion) for locking the power terminal block 60 with screws. The terminal block engaging portion 56 is a hole through which a screw is passed.

電源端子台６０は、長方体の箱形である。電源端子台６０は、電源端子台６０の電源端子６２を備えた面を取付面２００側に向けて、二次電池１０の電池開口部１１とユニットケース５０のケース切り欠き部５５と基板開口部３３とが略重なって形成される開口に挿入され固定される。図４に示すように、電源端子台６０の最下部（最も取付面２００から離れた部分）となる端子台最下部６３は、光源取付部５２の開口部の位置（光源取付部５２の最下部５２９）と略同一の位置（並列の位置関係）になることが望ましい。あるいは、端子台最下部６３が光源取付部５２の最下部５２９より、やや上部にあっても構わない。 The power terminal block 60 has a rectangular box shape. The power terminal block 60 has the battery terminal 11 of the secondary battery 10, the case notch 55 of the unit case 50, and the substrate opening with the surface of the power terminal block 60 provided with the power terminal 62 facing the mounting surface 200. 33 is inserted and fixed in an opening formed substantially overlapping. As shown in FIG. 4, the terminal block lowest part 63 that is the lowest part of the power terminal block 60 (the part farthest from the mounting surface 200) is the position of the opening of the light source mounting part 52 (the lowest part of the light source mounting part 52. 529) and substantially the same position (parallel positional relationship). Alternatively, the terminal block bottom 63 may be slightly above the bottom 529 of the light source mounting portion 52.

電源端子台６０は、取付面２００に対して垂直な状態よりも、やや傾斜して配置される。すなわち、取付面２００側に向けた電源端子６２の面を、ケース光源面５１の中心から周に向かう方向（図４におけるＢ方向）に傾斜させて、端子台最下部６３が光源取付部５２の最下部と略同一の位置（並列の位置関係）になるように調整する。電源端子台６０を上述したように調整した位置に配置して、電源端子台６０が装着する電源端子台取付金具６１の孔６４ａ，６４ｂと、ユニットケース５０の備える孔である端子台係止部５６ａ，５６ｂとを重ねてネジ止めする。電源端子台６０は、取付面２００に対して略垂直な状態で配置しても構わない。 The power terminal block 60 is disposed slightly inclined from the state perpendicular to the mounting surface 200. That is, the surface of the power supply terminal 62 facing the mounting surface 200 is inclined in the direction from the center of the case light source surface 51 to the periphery (direction B in FIG. 4), and the terminal block bottom 63 is the light source mounting portion 52.

The power terminal block 60 may be arranged in a state substantially perpendicular to the mounting surface 200.

ＬＥＤ７０及びレンズ７１は、照明器具１００の略中心部に位置するので、電源端子台６０を照明器具１００の略中心部からずらして、ＬＥＤ７０及びレンズ７１と電源端子台６０とを略並列の位置関係に配置することにより、同じ高さの空間に複数の部品（例えば、ＬＥＤ７０とレンズ７１と二次電池１０と電源端子台６０等）を配置することができ、照明器具の高さが部品の高さによって累積的に増加するのを防ぐことができる。すなわち、電源端子台６０は、取付面２００に設置される本体４０の略中心部から所定の距離ずれた位置に配置される。 Since the LED 70 and the lens 71 are located at substantially the center of the lighting fixture 100, the power terminal block 60 is shifted from the substantially central portion of the lighting fixture 100, and the LED 70 and lens 71 and the power terminal block 60 are in a substantially parallel positional relationship. By arranging the plurality of components, the plurality of components (for example, the LED 70, the lens 71, the secondary battery 10, the power terminal block 60, etc.) can be arranged in the same height space. Therefore, it is possible to prevent the cumulative increase. That is, the power supply terminal block 60 is disposed at a position that is shifted by a predetermined distance from the substantially central portion of the main body 40 installed on the mounting surface 200.

Can be.

また、本体４０は、本体４０の略中心部から所定の距離ずれた位置であって、電源端子台６０が配置された位置と重なる位置に、外部電源と電源端子６２とを接続する電線を通すための電源穴４１（貫通孔の一例）を設けている。 Further, the main body 40 passes an electric wire connecting the external power source and the power terminal 62 to a position that is shifted from the substantially central portion of the main body 40 by a predetermined distance and overlaps the position where the power terminal block 60 is disposed. A power supply hole 41 (an example of a through hole) is provided.

また、本体４０は、取付面２００に本体４０をネジ止めするための器具取付穴４２ａ、４２ｂを備えている。本体４０は、本体４０と点灯装置２０とが一体に取り付けられた状態のままで、本体４０の器具取付穴４２にネジを通して取付面２００にネジ止めすることができる構造となっている。本体４０の器具取付穴４２ａ、４２ｂの垂直軸上に、基板孔３２とケース孔５０１が位置するので、作業者は、本体４０に点灯装置２０を取り付けた状態のままで、ユニットケース５０のケース孔５０１からねじ回し具等を挿入して、さらに基板孔３２を通過して、本体４０の器具取付穴４２にねじ回し具等を到達させて本体４０を取付面２００にネジ止めすることができる。 Further, the main body 40 includes instrument mounting holes 42 a and 42 b for screwing the main body 40 to the mounting surface 200.

Since the substrate hole 32 and the case hole 501 are located on the vertical axis of the instrument mounting holes 42a and 42b of the main body 40, the operator can leave the lighting device 20 attached to the main body 40 and the case of the unit case 50. A screwdriver or the like is inserted from the hole 501, and further passes through the substrate hole 32 to reach the instrument mounting hole 42 of the main body 40, so that the main body 40 can be screwed to the mounting surface 200. .

図８は、点灯装置２０を取り付けた本体４０を取付面２００側から見た平面図である。図４、図８を用いて、本体４０の電源穴４１の形状と配置について説明する。 FIG. 8 is a plan view of the main body 40 with the lighting device 20 attached as viewed from the attachment surface 200 side. The shape and arrangement of the power supply holes 41 of the main body 40 will be described with reference to FIGS.

図４に示すように、電源端子台６０は、照明器具の略中心部Ｑ（すなわち、本体４０の略中心部Ｑ）から所定の距離ずれた位置であってユニットケース５０のケース切り欠き部５５と二次電池１０の電池開口部１１との位置に設置される。これは、二次電池１０、ＬＥＤ７０及びレンズ７１、電源端子台６０等の部品を並列な位置関係で配置することにより、照明器具１００の高さの低減化を図るための、本実施の形態に係る照明器具１００の特徴点のひとつである。 As shown in FIG. 4, the power terminal block 60 is located at a position shifted from the approximate center portion Q of the lighting fixture (that is, the approximate center portion Q of the main body 40) by a predetermined distance, and the case cutout portion 55 of the unit case 50. And the battery opening 11 of the secondary battery 10. This is due to the present embodiment for reducing the height of the luminaire 100 by arranging components such as the secondary battery 10, the LED 70 and the lens 71, and the power terminal block 60 in a parallel positional relationship. This is one of the feature points of the lighting fixture 100.

したがって、本実施の形態では、外部電源等と電源端子台６０が備える電源端子６２とを接続する電線６５を通すために、本体４０の電源穴４１（貫通項の一例）を、本体４０の略中心部からずれた位置であってユニットケース５０のケース切り欠き部５５と二次電池１０の電池開口部１１との位置、すなわち、電源端子台６０の電源端子６２の位置と重なる位置に形成する。 Therefore, in the present embodiment, the power supply hole 41 (an example of the penetrating term) of the main body 40 is used as an abbreviation of the main body 40 in order to pass the electric wire 65 that connects the external power supply or the like and the power supply terminal 62 provided in the power supply terminal block 60. It is formed at a position that is shifted from the center and overlaps the position of the case notch 55 of the unit case 50 and the battery opening 11 of the secondary battery 10, that is, the position of the power terminal 62 of the power terminal block 60. .

図８に示すように、電源穴４１は、本体４０の略中心部から電源端子台６０の位置と重なる位置まで連結して開口する長円となっている。これによって、本体４０の略中心部から所定の距離ずれた位置に配置された電源端子台６０にも、電線６５を容易に接続することができる。また、電源穴４１は、上述した長円に限られることなく、本体４０の略中心部から電源端子台６０の位置と重なる位置であって二次電池１０の電池開口部１１の位置まで連続して開口する形状であれば、長方形、楕円形、円形、矩形、菱形でも構わない。また、本体４０の略中心部から電源端子台６０の位置と重なる位置まで連結して開口していなくてもよい。すなわち、略円形でも略４角形でも略３角形でもよく、この場合は、本体４０と電源端子台６０が重なる位置に、略円形（あるいは、略４角形、略３角形等）の電源穴４１を設けることによって、電源端子６２と電線６５を接続することができる。したがって、電源穴４１は、本体４０と電源端子台６０（電源端子台６０の電源端子６２）の位置とが重なる位置に開口があればよく、どのような形状でも構わない。 As shown in FIG. 8, the power supply hole 41 is an ellipse that is connected and opened from a substantially central portion of the main body 40 to a position overlapping the position of the power supply terminal block 60. Accordingly, the electric wire 65 can be easily connected to the power supply terminal block 60 disposed at a position shifted from the substantially central portion of the main body 40 by a predetermined distance. Further, the power supply hole 41 is not limited to the above-described ellipse, and is continuous from the approximate center of the main body 40 to the position of the power supply terminal block 60 to the position of the battery opening 11 of the secondary battery 10. As long as the shape is open, a rectangle, an ellipse, a circle, a rectangle, or a rhombus may be used. Moreover, it is not necessary to connect and open from the substantially center part of the main body 40 to the position overlapping with the position of the power terminal block 60. That is, it may be approximately circular, approximately quadrangular, or approximately triangular. In this case, a substantially circular (or approximately rectangular, approximately triangular, etc.) power supply hole 41 is provided at a position where the main body 40 and the power supply terminal block 60 overlap. By providing, the power supply terminal 62 and the electric wire 65 can be connected. Therefore, the power supply hole 41 may have any shape as long as it has an opening at a position where the main body 40 and the power supply terminal block 60 (the power supply terminal 62 of the power supply terminal block 60) overlap each other.

図９（ａ）は、二次電池１０の正面図、図９（ｂ）は、二次電池１０を２枚重ねた場合のＡ方向側面図である。 FIG. 9A is a front view of the secondary battery 10, and FIG. 9B is a side view in the A direction when two secondary batteries 10 are stacked.

次に、図９を用いて、二次電池１０の形状と構成についてさらに詳しく説明する。 Next, the shape and configuration of the secondary battery 10 will be described in more detail with reference to FIG.

本実施の形態に係る二次電池１０は、リチウムポリマー電池である。リチウムポリマー電池は、例えば、電池の電解質として、ポリマーに電解液（例えば、リチウムイオン等）を含ませてゲル化した電解質を用いた二次電池である。電解質が準固体状態であるため液漏れしにくく、また、形状の柔軟性が高い。したがって、図９（ａ）に示すように、二次電池１０を上述したような形状（馬蹄形、Ｕ字状、コ字状）に形成することができる。 Secondary battery 10 according to the present embodiment is a lithium polymer battery. The lithium polymer battery is, for example, a secondary battery using an electrolyte gelled by containing an electrolyte (eg, lithium ion) in a polymer as an electrolyte of the battery. Since the electrolyte is in a quasi-solid state, liquid leakage is difficult and the shape is highly flexible. Therefore, as shown in FIG. 9A, the secondary battery 10 can be formed in the shape as described above (horse-shoe shape, U shape, U shape).

また、リチウムポリマー電池は、電池の容量を面積によって変更することができる。例えば、照明器具１００に対応する電池の最大容量から、二次電池１０として用いるリチウムポリマー電池の最大面積を割り出し、最大面積に対応する二次電池用ケースを作成して、その中にリチウムポリマー電池を必要容量分（必要枚数分）収容して、照明器具１００の二次電池１０として用いることができる。そのとき、上記二次電池用ケースの形状は、正面図は図９（ａ）の形状となるように作成し、高さは最大容量（面積）に対応するリチウムポリマー電池の枚数分の高さの二次電池用ケースを作成するとよい。図９（ｂ）に示すように、リチウムポリマー電池による二次電池１０は、薄さ約５ｍｍで形成することができ、２枚重ねても約１０ｍｍである。このように、リチウムポリマー電池による二次電池１０を用いることにより、より照明器具１００の高さを低くすることができる。 Further, in the lithium polymer battery, the capacity of the battery can be changed depending on the area. For example, the maximum area of a lithium polymer battery used as the secondary battery 10 is determined from the maximum capacity of the battery corresponding to the lighting fixture 100, a case for a secondary battery corresponding to the maximum area is created, and the lithium polymer battery is included therein. Can be used as the secondary battery 10 of the lighting apparatus 100. At that time, the shape of the case for the secondary battery is prepared so that the front view becomes the shape of FIG. 9A, and the height is the height of the number of lithium polymer batteries corresponding to the maximum capacity (area). A secondary battery case may be created. As shown in FIG. 9 (b), the secondary battery 10 made of a lithium polymer battery can be formed with a thickness of about 5 mm, and is about 10 mm even when two sheets are stacked. Thus, the height of the lighting fixture 100 can be further reduced by using the secondary battery 10 made of a lithium polymer battery.

また、図９に示す馬蹄形の外形を持つ電池ケース（図示せず）を作成し、電池ケース内に１枚または２枚の二次電池を収容してもよい。１枚の二次電池を収容する場合は、他の１枚分のスペースが空くことになるが、外形を変更せず、仕様に応じて１枚または２枚の二次電池を搭載することができる。 Further, a battery case (not shown) having a horseshoe-shaped outer shape shown in FIG. 9 may be created, and one or two secondary batteries may be accommodated in the battery case. When one secondary battery is accommodated, the space for the other one will be vacant, but without changing the outer shape, one or two secondary batteries may be mounted according to the specifications. it can.

二次電池１０は、リチウムポリマー電池に限られず、ユニットケース５０に装着することができる平板状の二次電池ならばよい。 The secondary battery 10 is not limited to a lithium polymer battery, and may be a flat secondary battery that can be attached to the unit case 50.

また、電力を充電することができる二次電池（蓄電池）でなくても構わない。この場合は、点灯装置２０に充電機能は必要なくなる。通常の電池であれば、随時電池交換の必要があるが、本実施の形態に係る照明器具１００であれば、上述したように電池交換も容易に行うことができる。 Moreover, it does not need to be a secondary battery (storage battery) which can charge electric power. In this case, the lighting device 20 does not need a charging function. If it is a normal battery, it is necessary to replace the battery as needed, but if it is the lighting fixture 100 which concerns on this Embodiment, as above-mentioned, battery replacement | exchange can also be performed easily.

また、本実施の形態では、光源としてＬＥＤを使用した場合について説明したが、これに限られるわけではなく、例えば、光源としてミニハロゲンランプを用いてもよい。光源にミニハロゲンランプを用いた場合は、光源取付部５２はミニハロゲンランプを装着するためのランプソケットを備える。 In the present embodiment, the case where an LED is used as a light source has been described. However, the present invention is not limited to this. For example, a mini halogen lamp may be used as a light source. When a mini halogen lamp is used as the light source, the light source mounting portion 52 includes a lamp socket for mounting the mini halogen lamp.

以上のように、本実施の形態によれば、器具の高さをより低くして、天井面からの出っ張りを少なくした天井面との一体感のある照明器具１００を提供することができる。さらには、器具の高さを低減しつつ、照明器具１００の着脱作業性を向上させることができるという効果を奏する。 As described above, according to the present embodiment, it is possible to provide the lighting apparatus 100 having a sense of unity with the ceiling surface in which the height of the apparatus is further reduced and the protrusion from the ceiling surface is reduced. Furthermore, there is an effect that the attaching / detaching workability of the lighting fixture 100 can be improved while reducing the height of the fixture.

The electric wire connecting the external power source and the lighting fixture is connected from the external power source to the power terminal of the power terminal block disposed at the substantially central portion of the lighting fixture through a power supply hole provided in the substantially central portion of the main body. Therefore, the height of the lighting fixture is about 68.4 mm, which is obtained by adding the height of the halogen lamp to the height of the power terminal block.

図１０（ｂ）に示すように、実施の形態２に係る照明器具９００は、電源端子台６０が照明器具９００の略中心部（すなわち、本体４０の略中心部）から所定の距離ずれた位置に配置されている。つまり、電源端子台６０とハロゲンランプ９０とは、並列の位置関係に配置されている。照明器具９００の本体４０は実施の形態１で説明したものと同一であり、本体４０の電源穴４１は、長円になっていて電源端子台６０が配置される位置と重なる位置が開口している。外部電源と照明器具９００とを接続する電線は、外部電源から電源穴４１を通って、照明器具９００の略中心部（すなわち、本体４０の略中心部）から所定の距離ずれた位置に配置されている電源端子台６０の電源端子６２に接続される。このように、ハロゲンランプ９０と電源端子台６０は並列の位置関係に配置することができるので器具の高さは４８．４ｍｍとなり、図１０（ａ）に示す比較例としての照明器具の器具の高さを２０ｍｍ短くすることができる。 As shown in FIG. 10B, in the lighting fixture 900 according to Embodiment 2, the position where the power terminal block 60 is shifted by a predetermined distance from the substantially center portion of the lighting fixture 900 (that is, the substantially central portion of the main body 40).

The power terminal 62 is connected to the power terminal 62 of the power terminal block 60. Thus, since the halogen lamp 90 and the power terminal block 60 can be arranged in a parallel positional relationship, the height of the fixture is 48.4 mm, and the fixture of the lighting fixture as a comparative example shown in FIG. The height can be shortened by 20 mm.

以上のように、ハロゲンランプ９０を用いた場合であっても、照明器具の低減化を図ることができる。また、本実施の形態と実施の形態１とを組み合わせた照明器具を提供することもできる。 As described above, even when the halogen lamp 90 is used, it is possible to reduce the lighting fixtures. Moreover, the lighting fixture which combined this Embodiment and Embodiment 1 can also be provided.
