Description

本発明は、照明器具の器具本体の取付金具に反射板を取り付けた際に、反射板を確実に接地する構造に関する。   The present invention relates to a structure for reliably grounding a reflection plate when the reflection plate is attached to a fixture of a fixture body of a lighting fixture.

従来、照明器具では、器具本体に制光部品として反射板やこの反射板に備えた複数のルーバーなどが取り付けられている。   2. Description of the Related Art Conventionally, in a lighting fixture, a reflector plate and a plurality of louvers provided in the reflector plate are attached to the fixture body as light control parts.

ルーバーを取り付けられた反射板を有する照明器具について、器具本体の取付部材の係止部に反射板の被係止部を係止する際に、この被係止部に形成された歯形が係止部の塗膜を剥離すると同時に自己の塗膜を剥離し、反射板と器具本体の取付部材を接触導通させるとともに、反射板を器具本体に取り付ける構造を備えたものがある(例えば、特許文献1。)。   For a lighting fixture having a reflector to which a louver is attached, when the locked portion of the reflector is locked to the locking portion of the mounting member of the fixture body, the tooth profile formed on the locked portion is locked. Some of them have a structure in which the coating film of the part is peeled off at the same time, the coating film of the self is peeled off, the reflection plate and the mounting member of the instrument main body are brought into contact conduction, and the reflection plate is attached to the instrument main body (for example, Patent Document 1). .)

特開2004−200079号公報(段落「0030」、図14)Japanese Patent Laying-Open No. 2004-200079 (paragraph “0030”, FIG. 14)

しかしながら、特許文献1では、照明器具の器具本体に反射板を係止する取付部材に反射板を取り付ける際、この取付部材の係止部の塗膜を剥離する反射板の被係止部に設けられた歯形により接触導通するため、照明器具が振動等を受けると反射板がガタ付いてしまい、取付部材の係止部を押さえていた被係止部の歯形が緩まり、係止部と被係止部の歯形の接触状態を保ち続けることができず、取付部材と反射板の接触導通を確実に確保することができないという課題があった。   However, in patent document 1, when attaching a reflecting plate to the attachment member which latches a reflecting plate to the fixture main body of a lighting fixture, it provides in the to-be-latched part of the reflecting plate which peels the coating film of the engaging part of this attaching member. Since the contact is conducted by the tooth profile, the reflector is rattled when the lighting fixture receives vibration, etc., and the tooth profile of the locked part holding the locking part of the mounting member loosens, and the locking part and the engaged part are engaged. There was a problem that the contact state of the tooth profile of the stop portion could not be kept, and contact conduction between the mounting member and the reflector could not be ensured.

本発明は、上記のような課題を解決するためになされたものであり、反射板の被係止穴の器具本体の設置面側かつ設置面側に対して略水平の一辺に同じ高さを有する2つの突起を形成し、この反射板を取付部材の係止部に取り付けたときのガタ付きをなくすとともに、同じ高さを有する2つの突起が取付部材の係止部の上面を均等に押さえて、接触状態を保ち続けることで確実に接触導通し、アース接地できる照明器具を提供することを目的とする。   The present invention has been made to solve the above-described problems, and has the same height on one side substantially horizontal with respect to the installation surface side and the installation surface side of the fixture body of the locking hole of the reflector. The two protrusions having the same height are eliminated, and the two protrusions having the same height uniformly hold the upper surface of the engaging part of the mounting member. It is an object of the present invention to provide a lighting fixture that can reliably contact and conduct grounding by maintaining a contact state and can be grounded.

本発明は、照明器具の器具本体に設けられた反射板取付部に嵌合する反射板の被係止穴の器具本体の設置面側かつ設置面側に対して略水平の一辺に2つの突起を同じ高さで形成し、この反射板を反射板取付部に取り付けるとき、反射板取付部の係止部は反射板を押し当てられて弾性変形し、反射板の被係止穴が反射板取付部の係止部に嵌合されると、反射板取付部の弾性変形が解除され、反射板を反射板取付部に係止するとともに被係止穴の突起が係止部に接触して反射板と器具本体とを電気的に接続させるものである。   The present invention provides two protrusions on one side of the mounting surface side of the fixture main body of the fixture plate of the reflector plate that fits into the reflector mounting portion provided in the fixture main body of the lighting fixture, and substantially horizontally on the installation surface side. When the reflector is attached to the reflector mounting portion, the locking portion of the reflector mounting portion is elastically deformed by being pressed against the reflector, and the locked hole of the reflector is the reflector When fitted to the locking portion of the mounting portion, the elastic deformation of the reflecting plate mounting portion is released, the reflecting plate is locked to the reflecting plate mounting portion, and the projection of the locked hole comes into contact with the locking portion. The reflector and the instrument body are electrically connected.

本発明によれば、照明器具の器具本体に設けられた反射板取付部に反射板を取り付けるとき、同じ高さで反射板の被係止穴の器具本体の設置面側かつ設置面側に対して略水平の一辺に形成された2つの突起が反射板取付部の係止部と接触して、反射板を反射板取付部に係止するとともに器具本体と反射板とを電気的に接続させることができる。反射板を反射板取付部に係止したとき、被係止穴の一辺に形成された突起が、反射板取付部の係止部との接触面を均等に押さえるので、器具本体に取り付けた反射板の自重により被係止穴の突起と反射板取付部の係止部との接触導通を保ち、反射板をガタ付かせずに確実にアース接地することができる。   According to the present invention, when the reflector is attached to the reflector attachment portion provided on the fixture body of the lighting fixture, the fixture body of the locked hole of the reflector is mounted on the fixture surface side and the installation surface side at the same height. The two projections formed on the substantially horizontal side come into contact with the locking portion of the reflection plate mounting portion to lock the reflection plate to the reflection plate mounting portion and to electrically connect the instrument body and the reflection plate. be able to. When the reflector is locked to the reflector mounting portion, the projections formed on one side of the locked hole evenly press the contact surface with the latching portion of the reflector mounting portion. The contact weight between the projection of the locked hole and the locking portion of the reflection plate mounting portion can be maintained by the weight of the plate, and the grounding can be reliably grounded without rattling the reflection plate.

照明器具1は、この照明器具1の外郭を形成し天井等に埋め込まれて設置される箱状の器具本体10と、この器具本体10の底面に取り付けられる反射板取付バネ30と、この反射板取付バネ30に取り付けられる反射板20と、この反射板20に取り付けられるルーバー40と、器具本体10に取り付けられ直管形蛍光ランプが装着されるランプソケット50と、器具本体10の底面に取り付けられる電源端子台60と、器具本体10の底面に取り付けられる点灯装置70と、から構成される。   The luminaire 1 includes a box-shaped luminaire main body 10 that forms an outline of the luminaire 1 and is embedded in a ceiling or the like, a reflector mounting spring 30 that is attached to the bottom surface of the luminaire main body 10, and the reflector The reflector 20 attached to the attachment spring 30, the louver 40 attached to the reflector 20, the lamp socket 50 attached to the instrument main body 10 and fitted with a straight tube fluorescent lamp, and the bottom of the instrument main body 10. The power terminal block 60 and the lighting device 70 attached to the bottom surface of the instrument body 10 are configured.

器具本体10は、導電性を有する金属板の表面を、絶縁性を有する絶縁膜として白色塗装で覆った底面部を有し、この底面部の部材により、一体あるいは複数の部材の組み合わせによって箱状に形成されている。   The instrument body 10 has a bottom surface portion in which the surface of a conductive metal plate is covered with white coating as an insulating film having an insulating property, and is formed into a box shape by one or a combination of a plurality of members by a member of the bottom surface portion. Is formed.

器具本体10は、その底面に反射板取付バネ30を取り付けて固定するための爪部11、角穴12及びバネ取付穴13等を有している。反射板取付バネ30に反射板20が取り付けられたとき、器具本体10の底面と反射板20の直管形蛍光ランプの光を反射する反射面の裏側の面との間に、電源線及び調光線等を接続する電源端子台60と、直管形蛍光ランプを点灯させるための電力を供給する点灯装置70が収納される。電源端子台60は、器具本体10の底面にネジ止めにより取り付けられ、電源線や調光線等で電気的に接続されるとともに、器具本体10へ取り付けられる底面に設けられた接地金具が器具本体10の非塗装部分に接触し、この電源端子台60を介して器具本体10がアース接地されている。器具本体10の両端の側面部には、ランプソケット50のソケット被取付部51を挿入して固定するためのソケット取付穴14が形成されている。   The instrument main body 10 has a claw portion 11, a square hole 12, a spring mounting hole 13, and the like for attaching and fixing the reflector mounting spring 30 to the bottom surface thereof. When the reflection plate 20 is attached to the reflection plate attachment spring 30, the power supply line and the control line are provided between the bottom surface of the instrument body 10 and the back surface of the reflection surface of the reflection plate 20 that reflects the light of the straight fluorescent lamp. A power supply terminal block 60 for connecting a light beam and the like and a lighting device 70 for supplying power for lighting the straight tube fluorescent lamp are housed. The power terminal block 60 is attached to the bottom surface of the instrument body 10 by screws, and is electrically connected by a power line, light adjustment or the like, and a grounding fitting provided on the bottom surface attached to the instrument body 10 is provided with the instrument body 10. The instrument body 10 is grounded via the power terminal block 60. Socket attachment holes 14 for inserting and fixing the socket attachment portions 51 of the lamp socket 50 are formed in the side surface portions at both ends of the fixture body 10.

反射板20は、ランプソケット50に取り付けられる直管形蛍光ランプが発する光を所定の配光で反射する反射面を有している。この反射面は、反射板20が器具本体10に取り付けられたとき、器具本体10から外部に露出した状態になる。反射板20は、金属製の平板を加工して形成されており、その反射面の表面全体が白色塗装されV字形状に折り曲げられている。   The reflection plate 20 has a reflection surface that reflects light emitted from the straight tube fluorescent lamp attached to the lamp socket 50 with a predetermined light distribution. The reflecting surface is exposed from the instrument body 10 to the outside when the reflector 20 is attached to the instrument body 10. The reflecting plate 20 is formed by processing a metal flat plate, and the entire surface of the reflecting surface is painted white and bent into a V shape.

反射板20には、この反射板20が反射板取付バネ30の反射板係止部31に嵌め込まれ係止される反射板被係止穴21が形成されている。この反射板被係止穴21は、V字形状に折り曲げられた反射板20の長手方向の中心線に対して、線対称に2箇所、また短手方向の中心線に対して線対称に2箇所、つまり1枚の反射板20につき合計4箇所設けられている。そして、反射板20のV字の折り曲げ部を下とした場合において、反射板被係止穴21の上側の一辺には、高さが0.5〜1.0mm程度のV字形状の突起22が、1つの反射板被係止穴21につき同じ高さ寸法で二つ形成されている。   The reflection plate 20 is formed with a reflection plate locking hole 21 in which the reflection plate 20 is fitted and locked in the reflection plate locking portion 31 of the reflection plate mounting spring 30. The reflector locking holes 21 are two symmetrically with respect to the center line in the longitudinal direction of the reflector 20 bent into a V shape, and two symmetrical with respect to the center line in the short direction. A total of four locations are provided per location, that is, one reflector 20. When the V-shaped bent portion of the reflecting plate 20 is located below, a V-shaped protrusion 22 having a height of about 0.5 to 1.0 mm is formed on one side above the reflecting plate locking hole 21. Are formed with the same height dimension per one reflecting plate locking hole 21.

この突起22が、反射板取付バネ30の反射板係止部31に反射板被係止穴21が嵌め込まれる際に、反射板係止部31に接触して擦られることによって縁部の塗膜を剥離され金属部を剥き出しされる。なお、このV字形状の突起22は、鈍角よりも鋭角である方が、反射板係止部31に嵌め込まれる際に、突起22の縁部の塗装を剥離しやすい。また、突起22のV字形状の先端部に丸みを帯びさせる加工をすると先端部が尖っている場合と比べて、突起22が反射板係止部31に接触する際に引っかかりにくくなり、滑りやすくなるので反射板係止部31の上面部とより接触しやすくすることができる。また、塗装を剥離するのに支障がない範囲で、突起22の先端部を平らにすると反射板係止部31の上面部と接触している面積が広がってより接触しやすくなり、接触導通の確実性を高めることができる。   When the reflection plate locking hole 21 is fitted into the reflection plate locking portion 31 of the reflection plate mounting spring 30, the protrusion 22 contacts and rubs the reflection plate locking portion 31 to thereby coat the coating film on the edge. And the metal part is exposed. In addition, when this V-shaped protrusion 22 has an acute angle rather than an obtuse angle, it is easier to peel off the coating of the edge of the protrusion 22 when the V-shaped protrusion 22 is fitted into the reflection plate locking portion 31. Further, when the V-shaped tip of the protrusion 22 is rounded, the protrusion 22 is less likely to be caught when coming into contact with the reflection plate locking portion 31 and is more slippery than when the tip is sharp. As a result, it is possible to make contact with the upper surface portion of the reflection plate locking portion 31 easier. In addition, if the tip of the protrusion 22 is flattened within a range where there is no problem in peeling off the coating, the area in contact with the upper surface of the reflection plate locking portion 31 is widened and more easily contacted. Certainty can be increased.

反射板20には、この反射板20の長手方向の中心軸に対して対称となる形状で、ルーバー40に形成されたルーバー被嵌込部41を嵌め込んで、ルーバー40を反射板20に固定するためのスリット23が、所定の数を一定の間隔を空けて形成されている。   A louver fitting portion 41 formed on the louver 40 is fitted into the reflecting plate 20 so as to be symmetrical with respect to the central axis in the longitudinal direction of the reflecting plate 20, and the louver 40 is fixed to the reflecting plate 20. A predetermined number of slits 23 are formed at regular intervals.

本実施の形態では、1つの反射板被係止穴21につき突起22を2箇所設けているが、突起22を3箇所以上設けてもよい。これらの突起22は、照明器具1を天井に設置した際、反射板取付バネ30に形成されたS字形状の反射板係止部31の上部に接触するように反射板20が器具本体10に取り付けられたときに、反射板被係止穴21の上部となる天井面側の一辺に設け、さらに、その水平方向における配置は反射板被係止穴21の天井面側の一辺の中心の垂線に対して線対称となるように設けると、反射板係止部31の上部に対して反射板20が振動等によりガタ付いて斜めに傾くことがなく、反射板取付バネ30に対して水平に取り付けられることで、反射板20と反射板取付バネ30の接触性がよくなり、導通がより確実になる。   In the present embodiment, two protrusions 22 are provided for each reflector locking hole 21, but three or more protrusions 22 may be provided. When the lighting fixture 1 is installed on the ceiling, these projections 22 are formed on the reflector main body 10 so that the reflector 20 contacts the upper part of the S-shaped reflector engaging portion 31 formed on the reflector mounting spring 30. When attached, it is provided on one side of the ceiling surface side, which is the upper part of the reflecting plate locking hole 21, and the horizontal arrangement thereof is a vertical line at the center of one side of the reflecting plate locking hole 21 on the ceiling surface side. If the reflection plate 20 is provided so as to be line-symmetric with respect to the upper portion of the reflection plate locking portion 31, the reflection plate 20 does not rattle due to vibration or the like and does not incline obliquely, and is horizontal to the reflection plate mounting spring 30. By attaching, the contact property of the reflecting plate 20 and the reflecting plate mounting spring 30 is improved, and conduction is more sure.

図6(b)において表示されている一点鎖線は、反射板20の反射板被係止穴21の上側の一辺(以下、上辺という)の中心に対する垂線(以下、中心線という)である。図6(b)では、2つの突起22の先端部がそれぞれ上辺の中心から距離bの位置にあるので中心線に対して線対称の位置にあることを示している。また、この2つの突起22の反射板被係止穴21の上辺からV字形状の先端まで距離aで同じ高さである。これによって、同じ高さの2つの突起22と反射板被係止穴21の下側の水平な一辺とで、S字形状の反射板係止部31の反射板被係止穴21から反射板20の外部に露出するU字部分を上下から水平に挟み込んで自重により均等な力で押さえることで、反射板20がガタついて斜めに傾くことがないようにしている。   6B is a vertical line (hereinafter referred to as a center line) with respect to the center of one side (hereinafter referred to as an upper side) on the upper side of the reflector locking hole 21 of the reflector 20. FIG. 6B shows that the tip portions of the two protrusions 22 are located at a distance b from the center of the upper side, and therefore are in a line-symmetrical position with respect to the center line. Further, the two projections 22 have the same height at a distance a from the upper side of the reflector locking hole 21 to the V-shaped tip. As a result, the reflecting plate locking hole 21 of the S-shaped reflecting plate locking portion 31 is reflected from the reflecting plate locking hole 21 by the two protrusions 22 having the same height and the horizontal side below the reflecting plate locking hole 21. The U-shaped portion exposed to the outside of 20 is sandwiched horizontally from above and below and pressed with an equal force by its own weight, so that the reflection plate 20 does not rattle and tilt.

なお、突起22の片方は、反射板係止部31を押さえるのに支障がない範囲で、上辺の中心から距離bよりも長い又は短い距離に設けてもよい。また、突起22は、反射板被係止穴21の上辺だけでなく、これに対向する床面側の一辺にも水平方向、垂直方向にそれぞれ上辺側の突起22と線対称となるようにもう一組設けてもよい。床面側の一辺に形成される突起22も反射板係止部31を押さえるのに支障がない範囲で、上辺に設けた突起22と非対称となる位置に設けてもよい。床面側の一辺に形成される突起22は反射板係止部31を押さえるのに支障がない範囲で、上辺に設けた突起22よりも数を少なくしてもよい。例えば、上辺に突起22を2つ形成し、これに対向する床面側の一辺に突起22を1つ形成する設け方がある。   One of the protrusions 22 may be provided at a distance that is longer or shorter than the distance b from the center of the upper side as long as there is no hindrance to pressing the reflection plate locking portion 31. Further, the protrusion 22 is line-symmetric with the protrusion 22 on the upper side in the horizontal direction and the vertical direction not only on the upper side of the reflecting plate locking hole 21 but also on one side of the floor surface facing this. One set may be provided. The protrusions 22 formed on one side of the floor surface may also be provided at positions that are asymmetric with the protrusions 22 provided on the upper side within a range that does not hinder the reflection plate locking portion 31. The number of the protrusions 22 formed on one side of the floor surface may be less than the number of the protrusions 22 provided on the upper side as long as there is no hindrance to pressing the reflection plate locking portion 31. For example, there is an installation method in which two protrusions 22 are formed on the upper side and one protrusion 22 is formed on one side of the floor surface facing this.

反射板取付バネ30は、導電性を有する金属で構成され、1枚の平板から切断又は型抜き等によって、切り取られた金属片のH字形状の底面部の4箇所の端部に被固定部33を形成し、この金属片を側面からみてS字形状になるように折り曲げることにより、図10に示すように、垂直方向の中心線に対して対称にS字形状の反射板係止部31を形成している。図10に示す一点鎖線は、反射板取付バネ30を側面からみたときの垂直方向の中心線を示している。また、この反射板取付バネ30の底面部には、エンボス加工により、三日月エンボス32、リブ34及び円形エンボス35が形成されている。反射板取付バネ30は、器具本体10の底面に設けられた4つの爪部11でH字形状の底面の四隅に形成された被固定部33を押さえられ、器具本体10に固定されている。また、反射板取付バネ30は、その底面部にリブ34を有しており、このリブ34で鉛直方向への底面部の曲がりを抑え、底面部の変形に対する強度を高めている。   The reflector mounting spring 30 is made of a conductive metal, and is fixed to the four end portions of the H-shaped bottom portion of the metal piece cut out or cut out from one flat plate. 33, and this metal piece is bent so as to have an S-shape when viewed from the side, and as shown in FIG. 10, the S-shaped reflecting plate locking portion 31 is symmetrical with respect to the vertical center line. Is forming. A one-dot chain line shown in FIG. 10 indicates a vertical center line when the reflector mounting spring 30 is viewed from the side. In addition, a crescent emboss 32, a rib 34, and a circular emboss 35 are formed on the bottom surface of the reflector mounting spring 30 by embossing. The reflector mounting spring 30 is fixed to the instrument body 10 by pressing the fixed parts 33 formed at the four corners of the H-shaped bottom surface by the four claws 11 provided on the bottom surface of the instrument body 10. Further, the reflector mounting spring 30 has a rib 34 on its bottom surface portion, and the rib 34 suppresses the bending of the bottom surface portion in the vertical direction and increases the strength against deformation of the bottom surface portion.

ルーバー40は、直管形蛍光ランプが点灯している状態において、照明器具1を使用者が視認した際に光源である直管形蛍光ランプを直接見てしまうことを防止(グレア低減)している。ルーバー40は、反射板20に一定の間隔を空けて形成されたスリット23に所定の枚数を取り付けられている。このとき、ルーバー40は、その長手方向の中心の上側に本体をV字状に切り取られルーバー被嵌込部41が形成されている。このルーバー被嵌込部41が、図8(a)に示す状態で反射板20のスリット23に嵌め込まれ、さらに図8(b)に示すように折り曲げられて反射板20に取り付け、固定される。   The louver 40 prevents the glare from being directly seen when the user visually recognizes the luminaire 1 when the straight fluorescent lamp is lit (reducing glare). Yes. A predetermined number of louvers 40 are attached to the slits 23 formed at a predetermined interval in the reflecting plate 20. At this time, the main body of the louver 40 is cut out in a V shape above the center in the longitudinal direction, and a louver-inserted portion 41 is formed. The louver fitted portion 41 is fitted into the slit 23 of the reflecting plate 20 in the state shown in FIG. 8A, and is further bent and attached to the reflecting plate 20 as shown in FIG. 8B. .

ルーバー40が取り付けられた反射板20を器具本体10に取り付ける前に、この器具本体10の底面には反射板取付バネ30、ランプソケット50、電源端子台60、点灯装置70及び直管形蛍光ランプ等が取り付けられ、各電気部品間の配線類の接続が完了している。そして、この状態でルーバー40と一体化された反射板20が、反射板取付バネ30に係止され器具本体10の底面に取り付けられることによって、照明器具1は、外部から反射板係止部31の露出部分を除いた反射板取付バネ30、電源端子台60、点灯装置70、ネジ類及び配線類等が覆い隠される構造となっている。このとき、直管形蛍光ランプ、ルーバー40と一体化した反射板20及び反射板20の反射板被係止穴21から外部に露出している反射板取付バネ30の反射板係止部31が、使用者から視認される状態となっている。   Before attaching the reflector 20 to which the louver 40 is attached to the instrument body 10, the reflector body mounting spring 30, the lamp socket 50, the power terminal block 60, the lighting device 70, and the straight tube fluorescent lamp are attached to the bottom surface of the instrument body 10. Etc., and the connection of wirings between the electrical components is completed. In this state, the reflector 20 integrated with the louver 40 is locked to the reflector mounting spring 30 and attached to the bottom surface of the fixture body 10, so that the lighting fixture 1 can be reflected from the outside by the reflector locking portion 31. The reflection plate mounting spring 30, the power terminal block 60, the lighting device 70, the screws, the wirings, and the like excluding the exposed portion are covered. At this time, the reflecting plate locking portion 31 of the reflecting plate mounting spring 30 exposed to the outside through the reflecting plate 20 integrated with the straight tube fluorescent lamp and the louver 40 and the reflecting plate locking hole 21 of the reflecting plate 20 is provided. It is in a state that is visible to the user.

ルーバー40は、ルーバー被嵌込部41をスリット23に嵌め込んで固定されることにより、反射板20と一体化されているので、直管形蛍光ランプを交換する際にはルーバー40と一体化した反射板20を器具本体10から取り外して古い直管形蛍光ランプを取り外し、新しい直管形蛍光ランプの取り付けが終わったら再びルーバー40と一体化した反射板20を器具本体10に取り付ける必要がある。また、反射板20を取り外すには、反射板被係止穴21を通して外部に露出している反射板係止部31を両側から2つ同時に押せばよい。反射板20が取り付けられた状態で反射板係止部31を両側から2つ同時に押すと、反射板20を係止していた反射板係止部31が緩み、さらに反射板20の自重によって反射板係止部31が反射板被係止穴21から抜けて反射板20の係止が解除され、反射板20が反射板取付バネ30から取り外される。   The louver 40 is integrated with the reflector 20 by fitting and fixing the louver fitted portion 41 into the slit 23, so that it is integrated with the louver 40 when replacing the straight fluorescent lamp. It is necessary to remove the old reflecting tube 20 from the instrument body 10 and remove the old straight tube fluorescent lamp, and to attach the reflecting plate 20 integrated with the louver 40 to the instrument body 10 again after the installation of the new straight tube fluorescent lamp. . Further, in order to remove the reflecting plate 20, it is only necessary to simultaneously press two reflecting plate locking portions 31 exposed to the outside through the reflecting plate locked holes 21 from both sides. When two reflection plate locking portions 31 are pressed simultaneously from both sides with the reflection plate 20 attached, the reflection plate locking portion 31 that has locked the reflection plate 20 is loosened and further reflected by its own weight. The plate locking portion 31 is removed from the reflecting plate locked hole 21 to release the locking of the reflecting plate 20, and the reflecting plate 20 is removed from the reflecting plate mounting spring 30.

ランプソケット50は、器具本体10の長手方向の両端の側面に2個ずつ取り付けられている。このランプソケット50は、器具本体10の底面に取り付けられた点灯装置70から電線で接続され、この点灯装置70から直管形蛍光ランプを点灯させるための電力を供給される。   Two lamp sockets 50 are attached to the side surfaces of both ends of the instrument body 10 in the longitudinal direction. The lamp socket 50 is connected by an electric wire from a lighting device 70 attached to the bottom surface of the fixture body 10, and is supplied with electric power for lighting the straight tube fluorescent lamp.

ランプソケット50は、その外郭に本体と一体的に形成されたソケット被取付部51により器具本体10の長手方向の両端の側面へ取り付けられる。このソケット被取付部51は、ランプソケット50の両側の側面に1箇所ずつ設けられており、その先端が球体の突起となっている。また、ソケット被取付部51には、その先端部の球体の突起を挿入するための穴を両端に2つ設けられたソケット固定板52が嵌め込まれている。   The lamp socket 50 is attached to the side surfaces at both ends in the longitudinal direction of the instrument main body 10 by socket attached portions 51 formed integrally with the main body on the outer shell. This socket attached portion 51 is provided on one side on both sides of the lamp socket 50, and the tip thereof is a spherical projection. In addition, a socket fixing plate 52 provided with two holes at both ends for inserting a spherical projection at the tip is fitted into the socket attached portion 51.

直管形蛍光ランプのランプソケット50への取付方法を説明する。照明器具1が天井に埋め込まれ設置された状態で、直管形蛍光ランプを器具本体10の底面に対して水平にし、かつその両端の電極ピンが天井面に対して垂直に並んだ状態で床面側に開いているランプソケット50の取付溝に挿入する。そして、直管形蛍光ランプの両端の電極ピンがランプソケット50の内部に完全に収納された後、直管形蛍光ランプを90度回転させる。これにより、直管形蛍光ランプがランプソケット50に固定され照明器具1に取り付けられる。   A method for attaching the straight tube fluorescent lamp to the lamp socket 50 will be described. With the luminaire 1 embedded and installed in the ceiling, the straight tube fluorescent lamp is leveled with respect to the bottom surface of the fixture body 10 and the electrode pins at both ends thereof are aligned vertically to the ceiling surface. It is inserted into the mounting groove of the lamp socket 50 opened on the surface side. Then, after the electrode pins at both ends of the straight tube fluorescent lamp are completely accommodated in the lamp socket 50, the straight tube fluorescent lamp is rotated by 90 degrees. Thus, the straight tube fluorescent lamp is fixed to the lamp socket 50 and attached to the lighting fixture 1.

電源端子台60は、商用電源から電力供給される電線と、点灯装置70にその商用電源の電力を供給するための電線が接続される。この電源端子台60は、ネジ止めにより器具本体10の底面に固定され取り付けられる。このとき、電源端子台60の底部に設けられた接地金具が器具本体10の底面に形成された接地穴に挿入され接触することによって、器具本体10がアース接地される。また、図中には表示されていないが、電源端子台60とは別に器具本体10の底面に点灯装置70に入力する調光信号用の電線を接続するための調光端子台を設けてもよい。   The power terminal block 60 is connected to an electric wire supplied with electric power from a commercial power source and an electric wire for supplying electric power of the commercial power source to the lighting device 70. The power terminal block 60 is fixed and attached to the bottom surface of the instrument body 10 by screwing. At this time, the grounding metal provided on the bottom of the power terminal block 60 is inserted into and contacted with a grounding hole formed on the bottom surface of the body 10, thereby grounding the body 10. Although not shown in the figure, a dimming terminal block for connecting a dimming signal wire to be input to the lighting device 70 may be provided on the bottom surface of the fixture body 10 separately from the power terminal block 60. Good.

点灯装置70は、商用電源から電源端子台60を通して電力を供給され、直管形蛍光ランプを点灯させるための電力をランプソケット50を通して直管形蛍光ランプに出力する。この点灯装置70は、ネジ止めにより器具本体10の底面に固定され取り付けられる。点灯装置70は、光源の点灯回路を構成する電気部品が実装されたプリント配線基板が点灯装置70に収納される際、この点灯装置70の底部を構成するベースに、プリント配線基板に実装されたアース接地用金具に形成された接地用穴部を通してネジ止めされることで、プリント配線基板と点灯装置70の外郭を形成する板金ケースが導通する。そして、点灯装置70が器具本体10の底面に形成された接地穴を兼ねるネジ穴にネジ止めされたとき、この点灯装置70の内部に取り付けられたプリント配線基板は、器具本体10の底面に取り付けられた電源端子台60を通してアース接地される。   The lighting device 70 is supplied with power from a commercial power source through the power terminal block 60, and outputs power for lighting the straight tube fluorescent lamp to the straight tube fluorescent lamp through the lamp socket 50. The lighting device 70 is fixed and attached to the bottom surface of the instrument body 10 by screwing. The lighting device 70 is mounted on the printed wiring board on the base constituting the bottom of the lighting device 70 when the printed wiring board on which the electrical components constituting the lighting circuit of the light source are mounted is accommodated in the lighting device 70. By screwing through a grounding hole formed in the grounding metal fitting, the printed wiring board and the sheet metal case that forms the outline of the lighting device 70 are electrically connected. When the lighting device 70 is screwed into a screw hole that also serves as a grounding hole formed on the bottom surface of the fixture body 10, the printed wiring board attached inside the lighting device 70 is attached to the bottom surface of the fixture body 10. The power supply terminal block 60 is grounded.

以下、反射板取付バネ30を器具本体10に取り付ける際の手順について図3に基づいて説明する。   Hereinafter, a procedure for attaching the reflector mounting spring 30 to the instrument body 10 will be described with reference to FIG.

反射板取付バネ30は、爪部11に対して器具本体10の底面部の短手方向からスライドさせて挿入し、その際、反射板取付バネ30の底面に設けられた三日月エンボス32が、器具本体10に設けられたバネ取付穴13に嵌め込まれ器具本体10の底面に固定される。このとき、反射板取付バネ30の底面に形成された三日月エンボス32は、最初に角穴12に嵌り、その状態から、さらにスライドさせることによってバネ取付穴13に達し、二つの三日月エンボス32がバネ取付穴13の両端に嵌め込まれ固定される。この角穴12は、反射板取付バネ30の三日月エンボス32をバネ取付穴13に嵌め込む際に、反射板取付バネ30の本体が斜めに傾いてしまうことを防止している。   The reflector mounting spring 30 is inserted into the claw portion 11 by sliding it from the short side of the bottom surface of the instrument body 10. At this time, the crescent emboss 32 provided on the bottom surface of the reflector mounting spring 30 is inserted into the instrument. The main body 10 is fitted into a spring mounting hole 13 and fixed to the bottom surface of the instrument main body 10. At this time, the crescent emboss 32 formed on the bottom surface of the reflector mounting spring 30 first fits into the square hole 12 and further slides from that state to reach the spring mounting hole 13 so that the two crescent embosses 32 are springs. It is fitted and fixed at both ends of the mounting hole 13. The square hole 12 prevents the body of the reflector mounting spring 30 from being inclined obliquely when the crescent emboss 32 of the reflector mounting spring 30 is fitted into the spring mounting hole 13.

また、反射板取付バネ30の被固定部33に形成された円形エンボス35が、器具本体10の底面への取り付けの際に爪部11との間に挟まり、この爪部11の下面に接触することで反射板取付バネ30が爪部11から抜けることあるいはずれることを防止している。これにより、反射板取付バネ30は、ネジを使用することなく器具本体10の底面に取り付け固定され、器具本体10と反射板20を電気的に接続し、ルーバー40と一体化された反射板20を器具本体10の電源端子台60を通してアース接地することができる。   Further, the circular emboss 35 formed on the fixed portion 33 of the reflection plate mounting spring 30 is sandwiched between the claw portion 11 and attached to the lower surface of the claw portion 11 when being attached to the bottom surface of the instrument body 10. This prevents the reflection plate mounting spring 30 from coming off or slipping out of the claw portion 11. Thereby, the reflector mounting spring 30 is attached and fixed to the bottom surface of the instrument body 10 without using a screw, electrically connects the instrument body 10 and the reflector 20, and is integrated with the louver 40. Can be grounded through the power terminal block 60 of the instrument body 10.

このとき、反射板取付バネ30は、その底面に設けられた三日月エンボス32によって取り付けられると同時に器具本体10の底面を削り、この器具本体10の表面に施された白色塗装が剥離されて生じた非塗膜部分と電気的に接続され、器具本体10の底面に取り付けられた電源端子台60を通してアース接地される。なお、あらかじめ三日月エンボス32が取り付けられる器具本体10の底面部付近を非塗装にしておくと、三日月エンボス32がバネ取付穴13の縁部に接触するだけで導通し、アース接地させることができる。   At this time, the reflection plate mounting spring 30 was generated by the crescent emboss 32 provided on the bottom surface thereof, and at the same time, the bottom surface of the device body 10 was shaved, and the white paint applied to the surface of the device body 10 was peeled off. It is electrically connected to the non-coating portion and grounded through a power terminal block 60 attached to the bottom surface of the instrument body 10. In addition, if the vicinity of the bottom surface portion of the instrument body 10 to which the crescent emboss 32 is attached is not coated, the crescent emboss 32 can be conducted only by contacting the edge of the spring mounting hole 13 and grounded.

本実施の形態において反射板取付バネ30は、器具本体10の短手方向の中心線と、器具本体10の長手方向の両端に取り付けられたランプソケット50との間に、短手方向の中心線に対して線対称となるように各1枚、1台の照明器具1につき合計2枚取り付けられる。また、本実施の形態では反射板取付バネ30は絶縁塗装されていないものを使用しているが、絶縁塗装されているものを使用してもよい。その場合、反射板取付バネ30を器具本体10の底面に取り付ける際に、器具本体10の底面の塗装だけでなく反射板取付バネ30の塗装も同時に剥離される。また、その場合、反射板係止部31の塗装は、反射板20を反射板係止部31に取り付けた際に嵌め込まれる反射板被係止穴21に形成された突起22が接触し擦ることで、この突起22の縁部の塗装と同時に剥離される。   In the present embodiment, the reflector mounting spring 30 is a center line in the short direction between the center line in the short direction of the instrument body 10 and the lamp sockets 50 attached to both ends in the longitudinal direction of the instrument body 10. In total, two pieces are attached to each one lighting device 1 so as to be line-symmetric with respect to each other. Further, in the present embodiment, the reflector mounting spring 30 is not coated with insulation, but may be coated with insulation. In that case, when attaching the reflector mounting spring 30 to the bottom surface of the instrument body 10, not only the paint on the bottom surface of the instrument body 10 but also the coating of the reflector attachment spring 30 is peeled off at the same time. Further, in this case, the coating of the reflection plate locking portion 31 is rubbed by the projection 22 formed in the reflection plate locking hole 21 fitted when the reflection plate 20 is attached to the reflection plate locking portion 31. Thus, the edge of the projection 22 is peeled off at the same time as the coating.

以下、ランプソケット50を器具本体10に取り付ける際の手順について図4に基づいて説明する。   Hereinafter, the procedure for attaching the lamp socket 50 to the instrument body 10 will be described with reference to FIG.

ランプソケット50を器具本体10に取り付けるには、箱状に形成された器具本体10の両端の側面部に形成されたソケット取付穴14に、ソケット被取付部51の先端の球体の突起を当てて押し込む。このとき、ソケット被取付部51の2つある突起の先端の球体の中心同士の距離より、2つあるソケット取付穴14の中心同士の距離の方が狭いため、ソケット被取付部51は内側に逆ハの字状に曲がり挿入される。   In order to attach the lamp socket 50 to the fixture body 10, the spherical protrusions at the tip of the socket attached portion 51 are applied to the socket attachment holes 14 formed at the side portions at both ends of the fixture body 10 formed in a box shape. Push in. At this time, since the distance between the centers of the two socket mounting holes 14 is narrower than the distance between the centers of the spheres at the tips of the two protrusions of the socket mounted portion 51, the socket mounted portion 51 is inward. It is bent and inserted into a reverse C shape.

ソケット被取付部51の先端の球体の突起が、ソケット取付穴14を通過すると、突起の先端部分の球体よりもソケット被取付部51の本体に一体形成されている根元から先端の球体部分を繋いでいる円柱部分の方が直径が小さいため、ソケット被取付部51は弾性力により元の状態に戻ろうとすることにより、内側から外側へ力が加わり、円柱部分の側面がソケット取付穴14の縁部に内側から外側に押し付ける力が働くことで、ソケット被取付部51はソケット取付穴14に固定される。また、このとき、ソケット被取付部51の先端に形成された球体の突起が、器具本体10の側面部を形成する金属板に外側から引っ掛ることで、ランプソケット50が器具本体10に形成されたソケット取付穴14から抜けることを防止している。   When the sphere protrusion at the tip of the socket attached portion 51 passes through the socket attachment hole 14, the sphere portion at the tip is connected from the root formed integrally with the main body of the socket attached portion 51 rather than the sphere at the tip portion of the protrusion. Since the diameter of the protruding cylindrical portion is smaller, the socket attached portion 51 tries to return to the original state by the elastic force, so that a force is applied from the inside to the outside, and the side surface of the cylindrical portion is the edge of the socket mounting hole 14. The socket mounting portion 51 is fixed to the socket mounting hole 14 by applying a pressing force to the portion from the inside to the outside. Further, at this time, the lamp socket 50 is formed on the fixture body 10 by the spherical protrusion formed at the tip of the socket attached portion 51 being hooked from the outside to the metal plate forming the side portion of the fixture body 10. The socket mounting hole 14 is prevented from coming off.

なお、ソケット取付穴14とソケット被取付部51の先端の球体の突起の直径は、同じ寸法又はソケット取付穴14の方を少し大きくするとよい。また、2つのソケット取付穴14の中心同士の距離は、ソケット被取付部51の円柱部分の中心同士の距離と同じ又はソケット被取付部51の円柱部分が内側から外側にソケット取付穴14の縁部を押す力が強くなるように少し狭くするとよい。ランプソケット50が、器具本体10のソケット取付穴14に挿入された後、ソケット被取付部51の先端に形成された球体の突起とソケット固定板52により、器具本体10の端部の側面の金属板が挟み込まれ、ランプソケット50が器具本体10に確実に固定される。   In addition, the diameter of the protrusion of the spherical body at the tip of the socket mounting hole 14 and the socket mounted portion 51 is preferably the same size or slightly larger in the socket mounting hole 14. Further, the distance between the centers of the two socket mounting holes 14 is the same as the distance between the centers of the cylindrical portions of the socket mounted portions 51, or the cylindrical portion of the socket mounted portions 51 extends from the inner side to the outer edge of the socket mounting holes 14. It is good to narrow a little so that the force which pushes a part may become strong. After the lamp socket 50 is inserted into the socket mounting hole 14 of the instrument main body 10, the metal on the side surface of the end of the instrument main body 10 is formed by the spherical protrusion formed at the tip of the socket attached portion 51 and the socket fixing plate 52. A board is inserted | pinched and the lamp socket 50 is fixed to the instrument main body 10 reliably.

以下、ルーバー40を反射板20に取り付ける際の手順及びその構造について図5に基づいて説明する。   Hereinafter, the procedure and structure when the louver 40 is attached to the reflecting plate 20 will be described with reference to FIG.

反射板20は、金属製の平板から切断、型抜き及び/またはレーザー等で略長方形の板金を切り出し、同時にV字形状の突起22が設けられた被係止穴21及びスリット23を開け、その表面全体を白色塗装によりコーティングされる前に、板金にV字形状の折り曲げ加工を施すことにより形成される。   The reflection plate 20 is cut from a metal flat plate by cutting, punching and / or cutting a substantially rectangular sheet metal, and at the same time, a locked hole 21 and a slit 23 provided with V-shaped projections 22 are opened, Before the entire surface is coated with white paint, it is formed by subjecting a sheet metal to V-shaped bending.

ルーバー40は、金属製の平板から切断及び/または型抜き等で略扇状の板金を切り出し、同時にルーバー被嵌込部41を設けられ形成される。このとき、ルーバー40は、図8(a)に示す状態となっている。このルーバー40のルーバー被嵌込部41を、反射板20に形成されたスリット23に嵌め込んで、さらに図8(b)に示すようにルーバー被嵌込部41を折り曲げて反射板20に固定し取り付ける。この時点では、反射板20及びルーバー40にはまだ塗装がされておらず、互いに剥き出しの金属部同士が接触しており、電気的に導通した状態となっている。   The louver 40 is formed by cutting a substantially fan-shaped sheet metal from a metal flat plate by cutting and / or die cutting and the like, and at the same time, a louver fitting part 41 is provided. At this time, the louver 40 is in the state shown in FIG. The louver fitted portion 41 of the louver 40 is fitted into the slit 23 formed in the reflecting plate 20, and the louver fitted portion 41 is further bent and fixed to the reflecting plate 20 as shown in FIG. And attach. At this time, the reflecting plate 20 and the louver 40 have not been painted yet, and the exposed metal portions are in contact with each other and are in an electrically conductive state.

次に、ルーバー40が取り付けられた反射板20は、ルーバー40と一体化した状態で白色塗装を施され、器具本体10に取り付けられる。そして、器具本体10の底面部から、その表面全体を絶縁塗装された反射板20の反射面が外部に露出し、その反射面で直管形蛍光ランプから発する光を反射する。このように、ルーバー40を反射板20に取り付けた後に、ルーバー40と一体化された反射板20が白色塗装されるので、この時点では反射板被係止穴21に形成された突起22は、塗膜で表面全体をコーティングされた状態になっている。なお、反射板20及びルーバー40は、互いに密着した状態で塗装される為、互いに接続された導通部まで絶縁塗料が進入しておらず、電気的に導通したままの状態である。ルーバー40と一体化した反射板20は、器具本体10に取り付けた際に外部に露出する反射面になる表面のみを塗装されている。   Next, the reflector 20 to which the louver 40 is attached is applied with white coating in a state of being integrated with the louver 40 and attached to the instrument body 10. And from the bottom face part of the instrument body 10, the reflection surface of the reflection plate 20 whose entire surface is insulated is exposed to the outside, and the light emitted from the straight tube fluorescent lamp is reflected by the reflection surface. Thus, since the reflector 20 integrated with the louver 40 is painted in white after the louver 40 is attached to the reflector 20, the protrusion 22 formed in the reflector locking hole 21 at this point is The entire surface is coated with a coating film. In addition, since the reflecting plate 20 and the louver 40 are coated in a state of being in close contact with each other, the insulating paint does not enter the conductive portions connected to each other, and is in an electrically conductive state. The reflecting plate 20 integrated with the louver 40 is painted only on the surface that becomes a reflecting surface exposed to the outside when the reflecting plate 20 is attached to the instrument body 10.

以下、反射板20を反射板取付バネ30に取り付ける際の手順及び反射板取付バネ30の形状の変化について図11乃至図13に基づいて説明する。   Hereinafter, a procedure for attaching the reflector 20 to the reflector attachment spring 30 and a change in the shape of the reflector attachment spring 30 will be described with reference to FIGS. 11 to 13.

The arrows in FIGS. 13C and 13D indicate the direction in which the shape of the spring changes.

反射板20を反射板取付バネ30に取り付ける前は、図13(a)の状態である。天井に埋め込まれた器具本体10の底面に取り付けられた反射板取付バネ30の反射板係止部31に、反射板20の反射面の裏側のV字形状の斜面を押し当てると図13(b)の状態になり、この状態から反射板20を天井方向に押し込むと図13(c)のように、反射板20のV字形状の斜面により反射板係止部31がF方向に押し込まれる。反射板20をこの状態からさらに押し込むと、反射板係止部31がさらに押し込まれ、図13(d)のように、反射板被係止穴21が反射板係止部31に達したとき、反射板係止部31が反射板取付バネ30の弾性力によって元の形状に戻ろうとしてG方向に開く。そして、反射板取付バネ30が元の形状に開き、反射板係止部31が反射板被係止穴21を通して外部に露出することで、反射板20が反射板係止部31に係止され器具本体10に取り付けられる。このとき、反射板係止部31が反射板被係止穴21に形成されたV字形状の突起22を擦ることで、突起22の縁部の塗膜が削られ剥離される。反射板20の反射板取付バネ30への係止が完了すると、バネの弾性力によって反射板取付バネ30が元の状態に戻り、図13(e)のように、反射板係止部31が反射板被係止穴21を通して外部に露出し、反射板20が器具本体10に取り付けられる。   Before the reflection plate 20 is attached to the reflection plate attachment spring 30, the state shown in FIG. When the V-shaped slope on the back side of the reflecting surface of the reflecting plate 20 is pressed against the reflecting plate locking portion 31 of the reflecting plate mounting spring 30 attached to the bottom surface of the instrument body 10 embedded in the ceiling, FIG. In this state, when the reflecting plate 20 is pushed in the ceiling direction, the reflecting plate locking portion 31 is pushed in the F direction by the V-shaped slope of the reflecting plate 20 as shown in FIG. When the reflecting plate 20 is further pushed in from this state, the reflecting plate locking portion 31 is further pushed, and when the reflecting plate locked hole 21 reaches the reflecting plate locking portion 31 as shown in FIG. The reflection plate locking portion 31 opens in the G direction to return to its original shape by the elastic force of the reflection plate attachment spring 30. Then, the reflecting plate mounting spring 30 opens to the original shape, and the reflecting plate locking portion 31 is exposed to the outside through the reflecting plate locking hole 21, so that the reflecting plate 20 is locked to the reflecting plate locking portion 31. It is attached to the instrument body 10. At this time, the reflecting plate locking portion 31 rubs the V-shaped protrusion 22 formed in the reflecting plate locked hole 21 so that the coating film at the edge of the protrusion 22 is scraped and peeled off. When the locking of the reflecting plate 20 to the reflecting plate mounting spring 30 is completed, the reflecting plate mounting spring 30 returns to the original state by the elastic force of the spring, and the reflecting plate locking portion 31 is moved as shown in FIG. The reflecting plate 20 is attached to the instrument body 10 by being exposed to the outside through the reflecting plate locking hole 21.

このとき、反射板20が係止されている反射板取付バネ30の反射板係止部31には、縁部の塗膜を剥離された突起22がその上部の曲面に接触しており、反射板20の自重によって下向きに力を受けている。この反射板係止部31の上部の曲面に、反射板20の自重によって突起22の剥き出しの金属部が触れ続けることで、反射板20が反射板取付バネ30と電気的に接続され導通すると同時に、反射板係止部31が突起22を下側から押さえて支える。また、反射板取付バネ30は、反射板被係止穴21の下側の一辺を反射板20の内側から外側へ働くバネの弾性力により、上部から下部へ押して反射板被係止穴21に反射板係止部31が嵌り込んで反射板20を固定することで、反射板20が床に落下することを防止している。   At this time, in the reflection plate locking portion 31 of the reflection plate mounting spring 30 where the reflection plate 20 is locked, the protrusion 22 from which the coating film on the edge portion is peeled is in contact with the curved surface at the top, A force is applied downward by the weight of the plate 20. When the exposed metal portion of the protrusion 22 is kept in contact with the curved surface of the upper portion of the reflection plate locking portion 31 by the weight of the reflection plate 20, the reflection plate 20 is electrically connected to the reflection plate mounting spring 30 and becomes conductive. The reflecting plate locking portion 31 supports the protrusion 22 by pressing it from below. The reflector mounting spring 30 pushes one side of the lower side of the reflector locking hole 21 from the upper part to the lower part by the elastic force of the spring acting from the inner side to the outer side of the reflecting plate 20 to the reflector locking hole 21. The reflection plate 20 is prevented from falling to the floor by fitting the reflection plate locking portion 31 and fixing the reflection plate 20.

本実施の形態によれば、反射板20を器具本体10に取り付けるとともに、反射板20の反射板被係止穴21に設けられたV字形状の突起22と、器具本体10に取り付けられた反射板取付バネ30の反射板係止部31が接触し擦られることにより、突起22の縁部の塗膜が剥離され、金属部分が剥き出しになり、ルーバー40と一体化した反射板20を取り付けるとともに接地するので、工事作業者及び使用者が、直管形蛍光ランプの交換作業等の際に反射板20及びルーバー40に触れて感電することを従来の照明器具と比べてより確実に防止することができる。   According to the present embodiment, the reflector 20 is attached to the instrument body 10, the V-shaped protrusion 22 provided in the reflector locking hole 21 of the reflector 20, and the reflector attached to the instrument body 10. When the reflection plate locking portion 31 of the plate attachment spring 30 is contacted and rubbed, the coating film on the edge of the protrusion 22 is peeled off, the metal portion is exposed, and the reflection plate 20 integrated with the louver 40 is attached. Since it is grounded, it is possible to more reliably prevent the construction worker and user from touching the reflector 20 and the louver 40 when replacing the straight fluorescent lamp, etc., compared to conventional lighting fixtures. Can do.

さらに、反射板20に形成された反射板被係止穴21の上辺の中心線に対して、線対称に同じ高さでV字形状の突起22を2つ形成することにより、これらの突起22が、反射板20を係止している反射板取付バネ30の反射板係止部31の上面を自重により均等に押さえるので、突起22と反射板係止部31の接触導通を保ってガタ付かず、反射板20及びルーバー40を確実にアース接地することができる。また、照明器具1が外部から振動を受けた場合においても反射板20を器具本体10に確実に固定することができる。   Further, by forming two V-shaped projections 22 with the same height symmetrically with respect to the center line of the upper side of the reflecting plate locking hole 21 formed in the reflecting plate 20, these projections 22 are formed. However, since the upper surface of the reflection plate locking portion 31 of the reflection plate mounting spring 30 that locks the reflection plate 20 is pressed evenly by its own weight, the contact conduction between the protrusion 22 and the reflection plate locking portion 31 is maintained, and there is a backlash. However, the reflector 20 and the louver 40 can be reliably grounded. Moreover, even when the lighting fixture 1 receives vibration from the outside, the reflector 20 can be reliably fixed to the fixture body 10.

本実施の形態では、直管形蛍光ランプを光源とした場合について説明しているが、光源は直管形LEDランプや有機EL等でもよい。   In this embodiment, the case where a straight tube fluorescent lamp is used as a light source is described, but the light source may be a straight tube LED lamp, an organic EL, or the like.

FIG. 16B is an enlarged view of a portion J in FIG. 16A, FIG. 17A is a cross-sectional view taken along line HH of the lighting apparatus in FIG. 14, and FIG. 17B is a view in FIG. It is a K section enlarged view.

照明器具1bは、その外郭を形成し天井等に取り付けられて設置される箱状の器具本体10bと、この器具本体10bに取り付けられる反射板20bと、器具本体10bに取り付けられ直管形蛍光ランプが装着されるランプソケット50と、器具本体10bの底面に取り付けられる電源端子台60と、器具本体10bの底面に取り付けられる点灯装置70と、から構成される。   The luminaire 1b includes a box-shaped fixture body 10b that forms an outer shell and is attached to a ceiling or the like, a reflector 20b that is attached to the fixture body 10b, and a straight tube fluorescent lamp that is attached to the fixture body 10b. The lamp socket 50 is mounted, the power terminal block 60 attached to the bottom surface of the appliance body 10b, and the lighting device 70 attached to the bottom surface of the appliance body 10b.

器具本体10bは、その底面に反射板20bを取り付けて固定する反射板取付爪15と、ランプソケット50を取り付けるためのソケット取付穴14と、電源端子台60及び点灯装置70等を取り付けるためのネジ穴等を有している。器具本体10bは、反射板取付爪15に反射板20bが取り付けられたとき、その底面と反射板20bとの間に電源端子台60及び点灯装置70等が収納される。器具本体10bは、その底面に取り付けられた電源端子台60を介してアース接地されている。   The fixture body 10b has a reflector mounting claw 15 for attaching and fixing the reflector 20b to the bottom surface thereof, a socket attachment hole 14 for attaching the lamp socket 50, a screw for attaching the power terminal block 60, the lighting device 70, and the like. Has holes and the like. When the reflection plate 20b is attached to the reflection plate attachment claw 15, the instrument body 10b houses the power terminal block 60, the lighting device 70, and the like between the bottom surface and the reflection plate 20b. The instrument body 10b is grounded via a power terminal block 60 attached to the bottom surface thereof.

器具本体10bと反射板20bは、塗装済みの金属製の平板を切り出し、型抜き及び/または折り曲げ等の加工により成形されるため、切り出しや穴開けによって金属部が剥き出しになった端部以外の表面全体は、塗装により絶縁性を有している。   Since the instrument main body 10b and the reflector 20b are formed by cutting a coated metal flat plate and performing processes such as die cutting and / or bending, other than the end portion where the metal portion is exposed by cutting or punching. The entire surface is insulative by painting.

反射板20bの反射板側面部24には、反射板被係止穴21bが形成されており、この反射板被係止穴21bが反射板取付爪15に嵌め込まれ、器具本体10bの底面に係止される。この反射板被係止穴21bは、V字形状に折り曲げられた反射板20bの長手方向の中心線に対して、線対称に2箇所、また短手方向の中心線に対して線対称に2箇所、つまり1枚の反射板20bにつき合計4箇所を反射板側面部24に設けられている。この反射板側面部24は、V字形状の反射板21bの上側の端部を天井面に対して垂直になるように折り曲げて形成される。また、反射板側面部24のV字の上側となる二辺の端部は、反射板20bの内側に向かって折り返されており、反射板20bの器具本体10bへの取り付け、取り外し作業の際に、この端部を作業者が直接手で触れないようになっている。   A reflecting plate locking hole 21b is formed in the reflecting plate side surface portion 24 of the reflecting plate 20b. The reflecting plate locking hole 21b is fitted into the reflecting plate mounting claw 15, and is engaged with the bottom surface of the instrument body 10b. Stopped. The reflector locking holes 21b are two symmetrically with respect to the center line in the longitudinal direction of the reflector 20b bent in a V shape, and two symmetrical with respect to the center line in the short direction. A total of four places are provided on the reflecting plate side face 24 per one reflecting plate 20b. The reflecting plate side surface portion 24 is formed by bending the upper end portion of the V-shaped reflecting plate 21b so as to be perpendicular to the ceiling surface. Moreover, the edge part of two sides used as the upper side of the V-shape of the reflector side surface part 24 is turned toward the inner side of the reflector 20b, and the reflector 20b is attached to and removed from the instrument body 10b. The end portion is not directly touched by the operator's hand.

反射板20bのV字の折り曲げ部を下とした場合において、反射板被係止穴21bの上側の一辺には、高さが0.5〜1.0mm程度のV字形状の突起22bが、1つの反射板被係止穴21bにつき同じ高さ寸法で二つ形成されている。反射板被係止穴21bは、塗装済みの金属板に切り出し、型抜き等によって形成されるので、その縁部は塗装が剥離されている。反射板20bを器具本体10bに取り付けるため、反射板取付爪15に反射板被係止穴21bが嵌め込まれる際に突起22bが反射板取付爪15に接触し、その表面を擦ることによって反射板取付爪15の上面の接触部の塗膜を剥離し、その金属部を剥き出しにする。   In the case where the V-shaped bent portion of the reflector 20b is on the bottom, a V-shaped protrusion 22b having a height of about 0.5 to 1.0 mm is formed on one side above the reflector locking hole 21b. Two reflection plates are formed at the same height per reflector locking hole 21b. The reflection plate locking hole 21b is cut out in a painted metal plate and formed by die cutting or the like, so that the coating is peeled off at the edge. In order to attach the reflector 20b to the instrument body 10b, when the reflector locking hole 21b is fitted into the reflector attachment claw 15, the projection 22b comes into contact with the reflector attachment claw 15 and rubs its surface to attach the reflector. The coating film on the contact portion on the upper surface of the nail 15 is peeled off, and the metal portion is exposed.

なお、本実施の形態の突起22bは塗装が剥離されているが、塗装が剥離されていなくてもよい。その場合、突起22bの先端部が尖っていると反射板取付爪15に取り付けた際の接触により、互いの接触部の塗装を剥離し、金属部を剥き出しにする。また、突起22bの先端部は実施の形態1と同様に丸みを付けてもよい。   In addition, although the coating of the protrusion 22b of the present embodiment is peeled off, the coating may not be peeled off. In that case, if the tip of the protrusion 22b is sharp, the paint on the contact portion is peeled off by contact with the projection 22b when the projection 22b is attached to the reflector mounting claw 15, and the metal portion is exposed. Further, the tip of the protrusion 22b may be rounded as in the first embodiment.

図16(b)において表示されている一点鎖線は、反射板20bの反射板被係止穴21bの上辺の中心線である。図16(b)では、2つの突起22bの先端部がそれぞれ上辺の中心から距離dの位置にあり、この中心線に対して対称の位置にあることを示している。また、この2つの突起22bの反射板被係止穴21bの上辺からV字形状の先端まで距離cで同じ高さである。これによって、反射板20bを反射板係止爪15に取り付けるとき、同じ高さの2つの突起22bが、反射板係止爪15の底面部の上面を水平に擦って表面の塗膜を削ることで確実に塗膜を剥離し、接触導通することができる。   The alternate long and short dash line displayed in FIG. 16B is the center line of the upper side of the reflecting plate locking hole 21b of the reflecting plate 20b. FIG. 16B shows that the tip portions of the two protrusions 22b are located at a distance d from the center of the upper side, and are symmetric with respect to the center line. Further, the two projections 22b have the same height at a distance c from the upper side of the reflector locking hole 21b to the V-shaped tip. Thus, when the reflection plate 20b is attached to the reflection plate locking claw 15, the two protrusions 22b having the same height horizontally rub the upper surface of the bottom surface of the reflection plate locking claw 15 to scrape the surface coating film. Thus, the coating film can be reliably peeled off and contact conduction can be achieved.

以下、反射板20bを反射板取付爪15に取り付ける際の手順及び反射板取付爪15の形状の変化について、図18乃至図20に基づいて説明する。   Hereinafter, a procedure for attaching the reflecting plate 20b to the reflecting plate attaching claws 15 and a change in the shape of the reflecting plate attaching claws 15 will be described with reference to FIGS.

図18は本実施の形態の反射板取り付け前の照明器具を示す部分斜視図、図19(a)は本実施の形態の反射板取り付け後の照明器具を示す部分斜視図、図19(b)は図19(a)のL部拡大図、図20(a)〜図20(d)は本実施の形態の反射板取り付け時の反射板の形状の変化を示す断面図である。図20(a)〜図20(c)の矢印は、反射板の形状が変化する方向を示している。   FIG. 18 is a partial perspective view showing the lighting fixture before attaching the reflector according to the present embodiment, FIG. 19A is a partial perspective view showing the lighting fixture after the reflector is attached according to the present embodiment, and FIG. FIG. 19A is an enlarged view of a portion L in FIG. 19A, and FIGS. 20A to 20D are cross-sectional views showing changes in the shape of the reflector when the reflector of this embodiment is attached. The arrows in FIGS. 20A to 20C indicate the direction in which the shape of the reflector changes.

天井に取り付けられた器具本体10bの底面の片側に形成された反射板取付爪15に、反射板20bの片側の反射板側面部24に形成された反射板被係止穴21bを嵌め込むと、図20(a)の状態になる。反射板被係止穴21bを反射板取付爪15に嵌め込むとき、反射板被係止穴21bに形成された突起22bを反射板取付爪15の底面部の上側の表面に擦りつけられ、その表面をコーティングしていた塗膜が剥離され金属部が剥き出しになり、突起22bの縁の金属部と接触し導通するとともに、反射板側面部24が反射板取付爪15の側面部に押し付けられる。反射板取付爪15の底面部には、器具本体10bの内側から外側に向けて高くなるように傾斜が付けられており、反射板被係止穴21bを嵌め込んだとき、突起22bが確実に接触できるようになっている。なお、反射板取付爪15の底面部に傾斜をつけるのではなく、Rを付ける加工をしてもよい。   When the reflection plate locking hole 21b formed in the reflection plate side surface portion 24 on one side of the reflection plate 20b is fitted into the reflection plate attachment claw 15 formed on one side of the bottom surface of the instrument body 10b attached to the ceiling, The state shown in FIG. When the reflection plate locking hole 21b is fitted into the reflection plate mounting claw 15, the protrusion 22b formed in the reflection plate locking hole 21b is rubbed against the upper surface of the bottom surface of the reflection plate mounting claw 15, The coating film that has been coated on the surface is peeled off, and the metal part is exposed, and is brought into contact with the metal part at the edge of the protrusion 22b to be conductive. The bottom surface of the reflection plate mounting claw 15 is inclined so as to increase from the inside to the outside of the instrument body 10b, and when the reflection plate locking hole 21b is fitted, the protrusion 22b is surely formed. It can be contacted. In addition, the process which attaches R instead of giving the inclination to the bottom face part of the reflector mounting claw 15 may be performed.

図20(a)の状態において、取り付けられた側の反射板側面部24は、反射板取付爪15の側面に押し当てられ、しっかりと固定されている。取り付けられていない側の反射板側面24は図20(a)のM方向の逆向きに押し込まれており、図20(a)の状態から反射板20bを押さえている力を緩めると、押し込まれていた側の反射板側面24は弾性力によって元の形状に戻ろうとし、M方向に広がる。その広がっていく反射板側面24の反射板被係止穴21bをもう一方の反射板取付爪15に押し当てると図20(b)の状態となる。反射板被係止穴21bと反射板取付爪15の位置をあわせて、M方向に広がろうとする反射板20bの弾性力に任せると、図20(c)に示すように反射板被係止穴21bが反射板取付爪15に嵌り込んでいく。すでに反射板被係止穴21bが嵌合されている側と同様、この反射板取付爪15の底面部は斜めに傾いており、器具本体10bの内側方向が低く、外側方向が高くなっている。そのため、反射板被係止穴21bが反射板取付爪15に嵌り込み始めた段階では、まだ突起22bが反射板取付爪15の底面部の上側の面に接触しておらず、ある程度の位置まで反射板被係止穴21bが嵌り込んだ段階から反射板取付爪15の底面部の接触面を擦り始める。そして、突起22bが反射板取付爪15の表面の塗装を削って剥離し、図20(d)のように、反射板被係止穴21bが反射板取付爪15に完全に嵌り込むと、突起22bの縁の金属部と反射板取付爪15の塗膜を剥離された底面部の上側の表面の剥き出しの金属部同士が接触し導通する。これにより、突起22bと反射板取付爪15を接触導通させるとともに、反射板側面部24が反射板取付爪15の側面部に押し付けられ、固定されることで反射板20bの器具本体10bへの取り付けが完了する。   In the state of FIG. 20A, the attached reflector side surface portion 24 is pressed against the side surface of the reflector attachment claw 15 and is firmly fixed. The side 24 of the reflector that is not attached is pushed in the direction opposite to the M direction in FIG. 20A. When the force holding the reflector 20b is released from the state shown in FIG. The side 24 of the reflecting plate that has been left tends to return to its original shape by the elastic force and spreads in the M direction. When the reflecting plate locking hole 21b on the side surface 24 of the reflecting plate that spreads is pressed against the other reflecting plate attachment claw 15, the state shown in FIG. When the positions of the reflection plate locking holes 21b and the reflection plate mounting claws 15 are aligned and left to the elastic force of the reflection plate 20b that attempts to spread in the M direction, as shown in FIG. The holes 21b are fitted into the reflector mounting claws 15. Similar to the side where the reflecting plate locking hole 21b is already fitted, the bottom surface portion of the reflecting plate attachment claw 15 is inclined obliquely, the inner direction of the instrument body 10b is low and the outer direction is high. . Therefore, at the stage where the reflection plate locking hole 21b starts to fit into the reflection plate attachment claw 15, the protrusion 22b has not yet contacted the upper surface of the bottom surface portion of the reflection plate attachment claw 15, and has reached a certain position. The contact surface of the bottom surface portion of the reflection plate mounting claw 15 starts to be rubbed from the stage where the reflection plate locking hole 21b is fitted. Then, the protrusion 22b removes the coating on the surface of the reflection plate mounting claw 15 and peels off, and the reflection plate locking hole 21b is completely fitted into the reflection plate mounting claw 15 as shown in FIG. The exposed metal parts on the upper surface of the bottom surface part from which the metal part at the edge of 22b and the coating film of the reflector mounting claw 15 are peeled off are brought into contact with each other. As a result, the projection 22b and the reflection plate mounting claw 15 are brought into contact with each other, and the reflection plate side surface 24 is pressed against and fixed to the side surface portion of the reflection plate mounting claw 15, whereby the reflection plate 20b is attached to the instrument body 10b. Is completed.

このとき、反射板20が係止されている反射板取付爪15の側面部を、反射板側面部24が内側から外側へ広がろうとする弾性力により押し込んでおり、反射板取付爪15との接触性をより高めている。同時に、反射板取付爪15の底面部の上側の表面に接触している突起22bが、反射板20bの自重によって下向きに力を受けている。この反射板取付爪15に、反射板20bの自重によって突起22bの剥き出しの金属部が触れ続けることで、反射板20bがより確実に接触導通され続けるとともに、反射板20bを反射板取付爪15により確実に固定し続ける。なお、反射板20bの幅が、この反射板20bを両側から固定する二組の反射板取付爪15同士の距離よりも若干狭いか同じ距離であれば、反射板20b自身の弾性力によって反射板取付爪15の側面部を押さえる力がうまく作用し、反射板20bを反射板取付爪15により確実に固定できるとともに、反射板20b自身の変形も抑えることができる。   At this time, the side surface portion of the reflection plate mounting claw 15 to which the reflection plate 20 is locked is pushed in by the elastic force that the reflection plate side surface portion 24 tries to spread from the inside to the outside. Increases contactability. At the same time, the protrusion 22b that is in contact with the upper surface of the bottom surface of the reflection plate mounting claw 15 receives a downward force due to the weight of the reflection plate 20b. Since the exposed metal portion of the protrusion 22b is kept in contact with the reflection plate mounting claw 15 due to the weight of the reflection plate 20b, the reflection plate 20b continues to be more reliably contacted and connected, and the reflection plate 20b is connected to the reflection plate mounting claw 15 by the reflection plate mounting claw 15. Continue to fix securely. If the width of the reflecting plate 20b is slightly smaller than or equal to the distance between the two pairs of reflecting plate mounting claws 15 that fix the reflecting plate 20b from both sides, the reflecting plate 20b itself has its elastic force to reflect the reflecting plate. The force which presses the side part of the attachment claw 15 acts well, and the reflection plate 20b can be securely fixed by the reflection plate attachment claw 15, and the deformation of the reflection plate 20b itself can also be suppressed.

本実施の形態は、実施の形態1と同様の効果が得られるとともに、反射板20bを器具本体10bに取り付けるために、この器具本体10bに一体的に形成された反射板取付爪15を使用するので、反射板取付具は不要となり、従来の照明器具と比べて部品点数を減らすことができる。また、構成部品を減らすことによって反射板取付具を器具本体10に取り付ける組立工程をなくすことができる。   In the present embodiment, the same effects as those of the first embodiment can be obtained, and in order to attach the reflector 20b to the instrument body 10b, the reflector plate claw 15 formed integrally with the instrument body 10b is used. Therefore, the reflector plate fixture is not necessary, and the number of parts can be reduced as compared with the conventional lighting fixture. Moreover, the assembly process which attaches a reflector mounting tool to the instrument main body 10 can be eliminated by reducing a component.

なお、本実施の形態において、反射板取付爪15は器具本体10bに一体的に形成されているが、別部品として器具本体10bの底面に取り付ける構造としてもよい。   In addition, in this Embodiment, although the reflecting plate attachment nail | claw 15 is integrally formed in the instrument main body 10b, it is good also as a structure attached to the bottom face of the instrument main body 10b as another component.
