Description

本発明は、反射板を器具本体の対向する二面間に取付けた照明器具に関するものである。   The present invention relates to a lighting fixture in which a reflector is attached between two opposing surfaces of a fixture body.

従来より、照明器具においては、蛍光ランプの光を所定方向へ反射させる反射板を設けるのが一般的である(例えば特許文献1参照)。
特許文献1に記載の照明器具においては、器具本体の前面に、ソケット台が取り付けられ、ソケット台には蛍光ランプを装着するランプソケットが設けられている。ソケット台と蛍光ランプとの間には、蛍光ランプの照射光を照射方向へ反射させる反射板が蛍光ランプの長手方向に沿って設けられている。ソケットは、反射板の長手方向両端部に設けられている切欠きから、反射板の前方に突出している。
Conventionally, in a luminaire, it is common to provide a reflecting plate that reflects light from a fluorescent lamp in a predetermined direction (see, for example, Patent Document 1).
In the lighting fixture described in Patent Document 1, a socket base is attached to the front surface of the fixture body, and a lamp socket for mounting a fluorescent lamp is provided on the socket base. Between the socket base and the fluorescent lamp, a reflector for reflecting the irradiation light of the fluorescent lamp in the irradiation direction is provided along the longitudinal direction of the fluorescent lamp. The socket protrudes forward of the reflecting plate from a notch provided at both ends in the longitudinal direction of the reflecting plate.

特開2001−006429号公報(第1図)JP 2001-006429 A (FIG. 1)

ところで、近年のインバータを用いた照明器具においては、雑音性能の向上を図る面から、反射板のアースが要求されるようになってきた。前述した特許文献1に記載の照明器具においては、反射板に先端部が器具本体側へ突出した爪が設けられており、爪の先端をソケットが取り付けられているソケット台に接触させることにより反射板のアースを行っている。   By the way, in recent lighting fixtures using an inverter, grounding of a reflector has been required from the viewpoint of improving noise performance. In the lighting fixture described in Patent Document 1 described above, the reflector is provided with a claw having a tip projecting toward the fixture main body, and reflection is achieved by bringing the tip of the claw into contact with a socket base to which a socket is attached. The board is grounded.

しかしながら、前述した特許文献1に記載の照明器具においては、ソケット台を介して反射板と器具本体との間の導通を図っているため、直接反射板と器具本体との間の導通を図って、反射板をより確実にアースすることが望ましい。   However, in the lighting fixture described in Patent Document 1 described above, since conduction between the reflector and the instrument main body is attempted through the socket base, direct conduction between the reflector and the instrument main body is intended. It is desirable to ground the reflector more reliably.

本発明は、従来の問題を解決するためになされたもので、反射板を確実にアースすることが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 conventional problems, and an object thereof is to provide a lighting fixture capable of reliably grounding a reflecting plate.

本発明の照明器具は、蛍光ランプを取付けるためのソケットと、前記蛍光ランプを点灯させるための点灯装置と、電力を供給するための電源端子台と、前記蛍光ランプを収容する金属製の器具本体と、を有し、前記蛍光ランプが前記器具本体の少なくとも一面を発光させるように配置された照明器具であって、前記蛍光ランプに沿って前記器具本体の対向する二面間にわたる反射板を設け、前記器具本体の二面に、内側へ突出して前記反射板に当接する爪を設けた構成を有している。   The lighting fixture of the present invention includes a socket for mounting a fluorescent lamp, a lighting device for lighting the fluorescent lamp, a power supply terminal block for supplying power, and a metal fixture main body that houses the fluorescent lamp. And the fluorescent lamp is arranged so that at least one surface of the fixture main body emits light, and a reflecting plate is provided between the two opposing surfaces of the fixture main body along the fluorescent lamp. The nail | claw which protrudes inside and contact | abuts to the said reflecting plate is provided in two surfaces of the said instrument main body.

この構成により、本発明にかかる照明器具では、器具本体に設けられている電源端子台から点灯装置に電力を供給し、ソケット用アダプタを介して器具本体に取り付けられているソケットに電力を供給して蛍光ランプを点灯させる。蛍光ランプから上方へ発せられた光を下方へ照射するために、蛍光ランプに沿って器具本体の対向する二面間に反射板が設けられている。また、器具本体の対向する二面には、内側へ突出して反射板に当接する爪が設けられている。このため、爪を通じて反射板と器具本体が直接導通するので、反射板を確実にアースすることができる。   With this configuration, in the lighting fixture according to the present invention, power is supplied to the lighting device from the power terminal block provided on the fixture body, and power is supplied to the socket attached to the fixture body via the socket adapter. Turn on the fluorescent lamp. In order to irradiate light emitted upward from the fluorescent lamp downward, a reflecting plate is provided between two opposing surfaces of the instrument body along the fluorescent lamp. Moreover, the nail | claw which protrudes inside and contact | abuts a reflecting plate is provided in two surfaces which an instrument main body opposes. For this reason, since a reflecting plate and an instrument main body conduct | electrically_connect directly through a nail | claw, a reflecting plate can be earth | grounded reliably.

また、本発明の照明器具は、前記爪は、前記反射板を装着する方向に向かうにつれて、突出量が大きくなるように傾斜面を有する構成を有している。   Moreover, the lighting fixture of this invention has the structure which the said nail | claw has an inclined surface so that protrusion amount may become large as it goes to the direction which mounts | wears with the said reflecting plate.

この構成により、爪の傾斜面が、反射板を装着する方向に向かって突出量が大きくなるため、反射板を器具本体へ取り付ける際に、爪の傾斜面が確実に反射板に接触する。このため、反射板を確実にアースすることができる。また、反射板を装着する際に、電線が爪に乗り上げていても、反射板によって押し上げられるので、電線を挟み込むのを防止することができる。   With this configuration, since the protruding amount of the inclined surface of the nail increases in the direction in which the reflecting plate is mounted, the inclined surface of the nail surely contacts the reflecting plate when the reflecting plate is attached to the instrument body. For this reason, the reflector can be reliably grounded. In addition, even when the electric wire rides on the claw when the reflective plate is mounted, it is pushed up by the reflective plate, so that the electric wire can be prevented from being caught.

本発明は、蛍光ランプから上方へ発せられた光を下方へ照射するために、蛍光ランプに沿って器具本体の対向する二面間に反射板が設けられている。また、器具本体の対向する二面には、内側へ突出して反射板に当接する爪が設けられている。このため、爪を通じて反射板と器具本体が直接導通するので、反射板を確実にアースすることができるという効果を有する照明器具を提供することができるものである。   In the present invention, in order to irradiate light emitted upward from the fluorescent lamp downward, a reflector is provided between two opposing surfaces of the instrument body along the fluorescent lamp. Moreover, the nail | claw which protrudes inside and contact | abuts a reflecting plate is provided in two surfaces which an instrument main body opposes. For this reason, since a reflecting plate and an instrument main body conduct | electrically_connect directly through a nail | claw, the lighting fixture which has the effect that a reflecting plate can be earth | grounded reliably can be provided.

図1および図2に示すように、本発明の実施形態にかかる照明器具10は、例えば、被取付部である天井11に設けられた照明器具用の開口12に埋め込んで用いることができる。天井11の開口12内部には、天井裏に配策されている商用電源に接続された電源線13および天井裏の強度部材に取り付けられた取付ボルト14(ここでは、二本)が配置されている。   As shown in FIG. 1 and FIG. 2, a lighting fixture 10 according to an embodiment of the present invention can be used by being embedded in, for example, an opening 12 for a lighting fixture provided in a ceiling 11 that is a mounted portion. Inside the opening 12 of the ceiling 11, a power line 13 connected to a commercial power source arranged in the back of the ceiling and mounting bolts 14 (two in this case) attached to a strength member on the back of the ceiling are arranged. Yes.

照明器具10は、下方が開口した矩形箱状の器具本体20を有し、天井11の開口12に嵌めこまれる。器具本体20の天板201の内面幅方向両端部には、長手方向に沿って例えば一対の直管型の蛍光ランプ21、21が配置されている。器具本体20には取付孔208が穿設されており、取付ボルト14を挿通させてナット141で締結し、天井11の開口12に取り付けられる。   The lighting fixture 10 has a rectangular box-like fixture body 20 that is open at the bottom, and is fitted into the opening 12 of the ceiling 11. For example, a pair of straight tube fluorescent lamps 21 and 21 are arranged along the longitudinal direction at both ends in the inner surface width direction of the top plate 201 of the instrument body 20. An attachment hole 208 is formed in the instrument body 20, and the attachment bolt 14 is inserted and fastened with a nut 141 to be attached to the opening 12 of the ceiling 11.

器具本体20の対向する二面である長手方向端部の縦壁204には、各蛍光ランプ21を取付けるための一対のソケット22、22が二組取り付けられている。両蛍光ランプ21の間には器具本体20の長手方向に沿って下方へ突出した山形状の反射板23が取り付けられており、反射板23は器具本体20に設けられている複数の反射板取付孔203に取り付けられる。反射板取付孔203は、器具本体の天板201にスリットを入れて、下方(図8においては上方)へ押し出して形成されている(図8参照)。   Two pairs of sockets 22, 22 for attaching each fluorescent lamp 21 are attached to the vertical wall 204 at the end in the longitudinal direction, which is two opposing surfaces of the instrument body 20. Between the two fluorescent lamps 21, a mountain-shaped reflector 23 protruding downward along the longitudinal direction of the instrument body 20 is attached, and the reflector 23 is attached to a plurality of reflectors provided on the instrument body 20. It is attached to the hole 203. The reflector mounting hole 203 is formed by slitting the top plate 201 of the instrument body and pushing it downward (upward in FIG. 8) (see FIG. 8).

器具本体20の天板201の内面幅方向中央部には、蛍光ランプ21を点灯させるための点灯装置である安定器24および電源線13に接続されて電力を供給するための電源端子台25が取り付けられている。電源端子台25は、天板201に設けられている電源孔202から電源線13を引き込んで接続される。安定器24は、電線(図示省略)で電源端子台25に接続されており、さらに、各ソケット22に接続されている。なお、安定器24、電源端子台25、電線等は反射板23の内部に収容されており、外部から見えないようになっている。   A ballast 24 that is a lighting device for lighting the fluorescent lamp 21 and a power supply terminal block 25 for supplying power by being connected to the power supply line 13 are provided in the central part in the inner surface width direction of the top plate 201 of the instrument body 20. It is attached. The power supply terminal block 25 is connected by drawing the power supply line 13 from the power supply hole 202 provided in the top plate 201. The ballast 24 is connected to the power terminal block 25 by an electric wire (not shown), and further connected to each socket 22. In addition, the ballast 24, the power supply terminal block 25, the electric wire, and the like are accommodated inside the reflection plate 23 so that they cannot be seen from the outside.

これにより、器具本体20に設けられている電源端子台25から安定器24に電力を供給し、器具本体20に取り付けられている各ソケット22に電力を供給して装着されている蛍光ランプ21を点灯させる。ここでは、蛍光ランプ21は、少なくとも下方へ照明光を照射する。   Thus, the fluorescent lamp 21 mounted by supplying power to the ballast 24 from the power terminal block 25 provided in the instrument body 20 and supplying power to each socket 22 attached to the instrument body 20 is provided. Light up. Here, the fluorescent lamp 21 emits illumination light at least downward.

次に、ソケット22の取付構造について詳述する。
図3および図4に示すように、ソケット22は、ソケット用アダプタ26を介して器具本体20に取り付けられている。ソケット22は樹脂製であり、前面221中央に蛍光ランプ21のランプピン(図示省略)に接触して電力を供給する端子部222を有する。ソケット22の後方には一対の突起223が設けられており、突起223をソケット用アダプタ26に設けられている取付孔261に挿嵌してソケット22を取り付ける。
Next, the mounting structure of the socket 22 will be described in detail.
As shown in FIGS. 3 and 4, the socket 22 is attached to the instrument body 20 via a socket adapter 26. The socket 22 is made of resin, and has a terminal portion 222 that supplies power in contact with a lamp pin (not shown) of the fluorescent lamp 21 at the center of the front surface 221. A pair of protrusions 223 are provided behind the socket 22, and the sockets 22 are attached by inserting the protrusions 223 into attachment holes 261 provided in the socket adapter 26.

図5にも示すように、ソケット用アダプタ26は金属の薄板を折り曲げて形成されており、裏側262には後方へ突出する一対の舌状の突出部263が設けられている。図6に示すように、突出部263の下面には、突出方向に直交する方向(すなわち、下方)に、切起こしにより爪部264が設けられている。例えば、爪部264は、突出部263にコ字状のスリットを設け、一辺265を中心としてスリットの内部を下方(図6(B)中矢印A方向)に折り曲げて形成されている。このとき、少なくとも爪部264の先端266の被覆を除去しておくのが望ましい。突出部263の表面(上面)から爪部264の先端までの高さH1は、器具本体20の縦壁204に設けられているアダプタ用の取付孔205の高さH2と略等しい。   As shown in FIG. 5, the socket adapter 26 is formed by bending a thin metal plate, and a pair of tongue-shaped protrusions 263 protruding backward are provided on the back side 262. As shown in FIG. 6, a claw portion 264 is provided on the lower surface of the protruding portion 263 by cutting and raising in a direction perpendicular to the protruding direction (that is, downward). For example, the claw portion 264 is formed by providing a U-shaped slit in the protruding portion 263 and bending the inside of the slit downward (in the direction of arrow A in FIG. 6B) around one side 265. At this time, it is desirable to remove at least the coating on the tip 266 of the claw portion 264. The height H1 from the surface (upper surface) of the protrusion 263 to the tip of the claw 264 is substantially equal to the height H2 of the adapter mounting hole 205 provided in the vertical wall 204 of the instrument body 20.

図4〜図7を参照して、ソケット22を器具本体20に取り付ける作業について説明する。図4に示すように、ソケット22の突起223をソケット用アダプタ26の取付孔261に挿嵌してソケット22をソケット用アダプタ26に取り付けて一体化する。次いで、図5および図6(B)に示すように、ソケット用アダプタ26の突出部263を、器具本体20の縦壁204に設けられているアダプタ用の取付孔205に挿入して、少なくとも爪部264を縦壁204の裏側に導出させる。そして、図7に示すように、突出部263を、爪部264が突出している側(図7中矢印A)へ折り曲げ、爪部264の先端266が縦壁204に当接するまで折り曲げる。   With reference to FIGS. 4-7, the operation | work which attaches the socket 22 to the instrument main body 20 is demonstrated. As shown in FIG. 4, the protrusion 223 of the socket 22 is inserted into the mounting hole 261 of the socket adapter 26, and the socket 22 is attached to the socket adapter 26 to be integrated. Next, as shown in FIG. 5 and FIG. 6B, the protruding portion 263 of the socket adapter 26 is inserted into the adapter mounting hole 205 provided in the vertical wall 204 of the instrument body 20, and at least the claws are inserted. The part 264 is led out to the back side of the vertical wall 204. Then, as shown in FIG. 7, the protruding portion 263 is bent toward the side where the claw portion 264 protrudes (arrow A in FIG. 7), and is bent until the tip 266 of the claw portion 264 contacts the vertical wall 204.

次に、反射板23の取付構造について詳述する。
図2および図8に示すように、反射板23は照射方向である下方(図8においては上方)へ突出する山形形状の反射面231を有しており、反射面231の左右両側には、器具本体20の天板201に当接する水平な取付面232が器具本体20の長手方向略全長にわたって設けられている。取付面232には、所定間隔で係止片233が設けられている。図8に示すように、係止片233は、取付面232の端部から所定間隔で一対のスリット234、234を設けることにより、両スリット234間に舌状に形成されている。
Next, the mounting structure of the reflecting plate 23 will be described in detail.
As shown in FIGS. 2 and 8, the reflecting plate 23 has a mountain-shaped reflecting surface 231 that protrudes downward in the irradiation direction (upward in FIG. 8), and on both the left and right sides of the reflecting surface 231, A horizontal mounting surface 232 that contacts the top plate 201 of the instrument body 20 is provided over substantially the entire length in the longitudinal direction of the instrument body 20. Locking pieces 233 are provided on the mounting surface 232 at a predetermined interval. As shown in FIG. 8, the locking piece 233 is formed in a tongue shape between the slits 234 by providing a pair of slits 234 and 234 at predetermined intervals from the end of the mounting surface 232.

一方、図2〜図4および図9に示すように、器具本体20の対向する二面である縦壁204の中央において反射板23の端部に対向する位置には、所定間隔で一対の爪206が各々設けられている。爪206は、器具本体20の内側へ突出して設けられており、反射板23を装着する方向(すなわち、器具本体20の天板201に向かう方向であり、図9(A)においては上向き)に向かうにつれて、突出量が大きくなるように傾斜面207を有する。   On the other hand, as shown in FIG. 2 to FIG. 4 and FIG. 206 are provided. The claw 206 is provided so as to protrude to the inside of the instrument main body 20, and in a direction in which the reflector 23 is attached (that is, a direction toward the top plate 201 of the instrument main body 20, and upward in FIG. 9A). The inclined surface 207 is provided so that the protruding amount increases as it goes.

図9(A)に示すように、例えば、爪206は、器具本体20の縦壁204に、く字状の二辺からなるスリット208、209を設け、他の一辺を基線にして器具本体20の内側へ折り曲げることにより形成できる。スリット208およびスリット209は、器具本体20の幅方向中央に向かって形成することにより、反射板23の内部に隠されるので、外観を損ねない。なお、爪206を切起こしで設けるので、傾斜面207には塗装等の被覆で覆われることはないが、確実に導通を図るため、傾斜面207および傾斜面207の周囲の被覆は、除去しておくのが望ましい。   As shown in FIG. 9 (A), for example, the claw 206 is provided with slits 208 and 209 having two square sides on the vertical wall 204 of the instrument body 20, and the instrument body 20 with the other side as a base line. It can be formed by bending inward. By forming the slit 208 and the slit 209 toward the center of the instrument body 20 in the width direction, the slit 208 and the slit 209 are concealed inside the reflection plate 23, and thus the appearance is not impaired. Since the claw 206 is cut and raised, the inclined surface 207 is not covered with a coating such as paint. However, in order to ensure conduction, the inclined surface 207 and the coating around the inclined surface 207 are removed. It is desirable to keep it.

このとき、上側のスリット208の長さが爪206の突出量となる。また、一対の爪206、206の間隔は、反射板23を器具本体20の天板201に取り付けた際に、爪206の一部が反射板23の反射面231の内面に接触する間隔とする。   At this time, the length of the upper slit 208 is the protrusion amount of the claw 206. Further, the interval between the pair of claws 206 and 206 is an interval at which a part of the claw 206 contacts the inner surface of the reflection surface 231 of the reflection plate 23 when the reflection plate 23 is attached to the top plate 201 of the instrument body 20. .

図10を参照して、反射板23の器具本体20への取り付け方を説明する。
まず、図10(A)に示すように、反射板23の一方の反射面231に設けられている係止片233を、器具本体20の天板201に設けられている反射板取付孔203に挿入する(図10(A)中矢印A)。この際、器具本体20の縦壁204に設けられている一対の爪206が、反射板23の長手方向両端部において、山形の反射面231の内部に収容されるようにする。
With reference to FIG. 10, the attachment method to the instrument main body 20 of the reflecting plate 23 is demonstrated.
First, as shown in FIG. 10A, the locking piece 233 provided on one reflection surface 231 of the reflection plate 23 is inserted into the reflection plate attachment hole 203 provided on the top plate 201 of the instrument body 20. Insert (arrow A in FIG. 10A). At this time, the pair of claws 206 provided on the vertical wall 204 of the instrument main body 20 are accommodated inside the angled reflecting surface 231 at both longitudinal ends of the reflecting plate 23.

次いで、図10(B)に示すように、反射面231を一対の爪206に被せるようにして、両取付面232が接近するように反射面231を弾性的に変形させ(図10(B)中矢印B1)、反射面231に設けられている係止片233を器具本体20の天板201に設けられている反射板取付孔203に挿入する(図10(B)中矢印B2)。   Next, as shown in FIG. 10B, the reflective surface 231 is covered with the pair of claws 206, and the reflective surface 231 is elastically deformed so that both the mounting surfaces 232 approach each other (FIG. 10B). Middle arrow B1), the locking piece 233 provided on the reflecting surface 231 is inserted into the reflector mounting hole 203 provided in the top plate 201 of the instrument body 20 (arrow B2 in FIG. 10B).

その後、図10(C)に示すように、手を離して反射板23の弾性力により係止片233を反射板取付孔203に押し込む。このとき、山形の反射面231は、反射板23の弾性力により天板201側へ変位するので(図10(C)中矢印C)、反射面231の内面が爪206に押し付けられる。   Thereafter, as shown in FIG. 10C, the hand is released and the locking piece 233 is pushed into the reflection plate mounting hole 203 by the elastic force of the reflection plate 23. At this time, the mountain-shaped reflecting surface 231 is displaced to the top plate 201 side by the elastic force of the reflecting plate 23 (arrow C in FIG. 10C), so that the inner surface of the reflecting surface 231 is pressed against the claw 206.

なお、反射板23を取り付けた際に、幅方向にずれた場合でも、図9(B)に示すように、少なくとも一方の爪206が反射板23と接触するので、導通を図ることができる。
また、反射板23が長手方向へずれた場合でも、図11に示すように、反射板23は長手方向の一方の爪206に接触するので、導通を図ることができる。
また、図12(A)に示すように、ソケット22と安定器24を接続する電線27が爪206の傾斜面207に接触している場合でも、図12(B)に示すように、反射板23を器具本体20の天板201側へ押し込む際に、反射板23が電線27を押し上げるので、線噛みするのを防止することができる。
Even when the reflecting plate 23 is displaced in the width direction when the reflecting plate 23 is attached, at least one of the claws 206 is in contact with the reflecting plate 23 as shown in FIG.
Further, even when the reflecting plate 23 is displaced in the longitudinal direction, as shown in FIG. 11, the reflecting plate 23 contacts one of the claws 206 in the longitudinal direction, so that conduction can be achieved.
Further, as shown in FIG. 12A, even when the electric wire 27 connecting the socket 22 and the ballast 24 is in contact with the inclined surface 207 of the claw 206, as shown in FIG. Since the reflecting plate 23 pushes up the electric wire 27 when the 23 is pushed into the top plate 201 side of the instrument body 20, it is possible to prevent the wire from being bitten.

以上、説明したように、本発明の実施形態にかかる照明器具10によれば、器具本体20に取付けられているソケット用アダプタ26の突出部263を、器具本体20に設けられているアダプタ用の取付孔205に挿通して裏側に導出させる。そして、突出部205を、突出部205の突出方向に直交する方向に設けられている爪部264側へ折り曲げて、爪部264を器具本体20に当接させるので、ソケット用アダプタ26を器具本体20に取付けてガタつきを防止するとともに、ソケット用アダプタ26を器具本体20に確実にアース導通させることができる。   As described above, according to the lighting fixture 10 according to the embodiment of the present invention, the protruding portion 263 of the socket adapter 26 attached to the fixture body 20 is provided for the adapter provided in the fixture body 20. It is inserted through the mounting hole 205 and led out to the back side. And since the protrusion part 205 is bend | folded to the nail | claw part 264 side provided in the direction orthogonal to the protrusion direction of the protrusion part 205, the nail | claw part 264 is contact | abutted to the instrument main body 20, Therefore The adapter 26 for sockets is attached to an instrument main body. The socket adapter 26 can be securely grounded to the instrument body 20 while being attached to the bracket 20 to prevent rattling.

また、突出部263を器具本体20の取付孔205に挿通する前に、突出部263の爪部264の先端266を覆っている被覆層を除去するので、ソケット用アダプタ26を器具本体20に確実にアース導通させることができる。   In addition, since the covering layer covering the tip 266 of the claw portion 264 of the protruding portion 263 is removed before the protruding portion 263 is inserted into the mounting hole 205 of the device main body 20, the socket adapter 26 is securely attached to the device main body 20. Can be grounded.

また、器具本体20の対向する二面である縦壁204には、内側へ突出して反射板23に当接する爪206が設けられているので、爪206を通じて反射板23と器具本体20が直接導通し、ネジのような別部品を設けることなく、反射板23を確実にアースすることができる。   Further, the vertical wall 204, which is the two opposing surfaces of the instrument body 20, is provided with a claw 206 that protrudes inward and abuts against the reflector 23, so that the reflector 23 and the instrument body 20 are directly conducted through the claw 206. In addition, the reflector 23 can be reliably grounded without providing another component such as a screw.

また、爪206の傾斜面207が、反射板23を装着する方向に向かって突出量が大きくなっているため、反射板23を器具本体20へ装着する際に、爪206の傾斜面207が確実に反射板23に接触する。このため、反射板23を確実にアースすることができる。また、反射板23を器具本体20に装着する際に、電線が爪206に乗り上げていても、反射板23によって傾斜面207に沿って押し上げられるので、電線を挟み込むのを防止することができる。   Further, since the protruding amount of the inclined surface 207 of the claw 206 increases in the direction in which the reflecting plate 23 is attached, the inclined surface 207 of the claw 206 is surely attached when the reflecting plate 23 is attached to the instrument body 20. In contact with the reflector 23. For this reason, the reflecting plate 23 can be reliably grounded. Further, when the reflector 23 is mounted on the instrument main body 20, even if the electric wire rides on the claw 206, it is pushed up along the inclined surface 207 by the reflector 23, so that the electric wire can be prevented from being caught.

なお、本発明の照明器具10は、前述した実施形態に限定されるものでなく、適宜な変形,改良等が可能である。
例えば、前述した実施形態においては、器具本体20の縦壁204に二個の爪206を設けた場合について例示したが、爪206の数は限定するものではない。
