これにより、図１（ｂ）に示すように、弾性部材３０ａが傾斜して軸支されているので、開放したとき（図中一点鎖線）の本体枠１４底辺からの高さ寸法ｃが、閉じたとき（図中実線）の高さ寸法ｄより大きくなる（ｃ＞ｄ）。すなわち、弾性部材３０ａを回動すると、先端の係合部３０ａ２が本体枠１４の縁を乗り越え、枠体１４ａ内に沈むようにして入り込む。 As a result, as shown in FIG. 1B, the elastic member 30a is tilted and pivotally supported, so that the height dimension c from the bottom of the main body frame 14 when the elastic member 30a is opened (the dashed line in the figure) is closed. (C> d). That is, when the elastic member 30a is rotated, the engaging portion 30a2 at the tip gets over the edge of the main body frame 14 and enters into the frame body 14a so as to sink.

また、図４（ｃ）に示すように、発光パネルＡの放熱板１１ｊには、回動される弾性部材３０ａの位置決め手段が設けられる。位置決め手段は、少なくとも放熱板１１ｊに設けられ弾性部材の先端の係合部３０ａ２が係合可能な複数個、本実施例では、３個の小孔３２として直線ｙ−ｙに沿って、略一直線状に配置され形成される。各小孔には「高」「中」「低」のマークを表示する。 Moreover, as shown in FIG.4 (c), the heat sink 11j of the light emission panel A is provided with the positioning means of the elastic member 30a rotated. The positioning means is provided at least on the heat radiating plate 11j and is engageable with a plurality of engaging portions 30a2 at the tip of the elastic member. In the present embodiment, the positioning means is substantially straight along the straight line yy as three small holes 32. Arranged in a shape. Each small hole is displayed with a mark of “high”, “medium”, and “low”.

この位置決め手段としての小孔３２は、支持部材３０の弾性部材３０ａが上記のように回動することによって、枠体１４ａ内に沈み込む寸法、すなわち、入り込む寸法ｄが回動に伴って連続して変わるので、３個の小孔を選択して発光パネルＡを本体枠１４に支持するときの高さを調整することができる。すなわち、支持部材３０が発光パネルＡを本体枠１４に押圧する本体枠の軸心方向ｘ−ｘの位置に対応して設けられた位置決め手段３２によって位置決めできるように構成される。なお、図２（ｂ）（ｃ）に示すように、３個の小孔３２は、上述した反射体１１ｃの空洞部１１ｇに対向する放熱板１１ｊおよび基板１１ａに貫通させて形成する。これにより、係合部３０ａ２がＬＥＤ１１と干渉することが防止される。 The small hole 32 as the positioning means has a dimension that sinks into the frame body 14a when the elastic member 30a of the support member 30 is rotated as described above, that is, a dimension d that enters is continuous with the rotation. Therefore, the height when the light emitting panel A is supported on the main body frame 14 by selecting three small holes can be adjusted. That is, the support member 30 can be positioned by positioning means 32 provided corresponding to the position in the axial direction xx of the main body frame that presses the light emitting panel A against the main body frame 14. As shown in FIGS. 2B and 2C, the three small holes 32 are formed so as to penetrate the radiator plate 11j and the substrate 11a facing the cavity 11g of the reflector 11c described above. Thereby, it is prevented that the engaging part 30a2 interferes with LED11.

上記に構成された支持部材３０および小孔３２により、発光パネルＡを本体枠１４内に支持する。先ず図４（ａ）に示すように、本体枠１４の枠体１４ａ内に、制光体１９、透光板１８、さらに発光パネルＡを順に挿入し、制光体１９を本体枠の鍔部１４ｎの内面に係止させる。 The light emitting panel A is supported in the main body frame 14 by the support member 30 and the small holes 32 configured as described above. First, as shown to Fig.4 (a), the light control body 19, the translucent board 18, and also the light emission panel A are inserted in order in the frame 14a of the main body frame 14, and the light control body 19 is inserted into the collar part of a main body frame. It is made to latch on the inner surface of 14n.

次いで、支持部材３０の軸支部材３０ｂを枠体１４ａの対角線上に対向する角に近い位置の側板１４ｋの溝１４ｑに嵌め込み、弾性部材３０ａを本体枠１４の軸心方向ｘ−ｘに弾性変形させながら枠体１４ａ側に回動すると先端の係合部３０ａ２が本体枠１４の縁に掛かることなく乗り越え、発光パネルの上面の放熱板１１ｊに当接し仮止めされる。さらにワイヤーの弾性力に抗しながら回動し、位置決め手段の「高」の表示のされた小孔３２に先端の係合部３０ａ２を挿入して係合させる。 Next, the shaft support member 30b of the support member 30 is fitted into the groove 14q of the side plate 14k close to the opposite corner on the diagonal line of the frame body 14a, and the elastic member 30a is elastically deformed in the axial direction xx of the main body frame 14. When it is turned to the frame body 14a side, the engaging portion 30a2 at the front end gets over the edge of the main body frame 14 and comes into contact with the heat radiating plate 11j on the upper surface of the light emitting panel to be temporarily fixed. Further, it rotates while resisting the elastic force of the wire, and the engaging portion 30a2 at the tip is inserted into and engaged with the small hole 32 on which “high” is indicated on the positioning means.

これにより、ワイヤーの弾性力により発光パネルＡ、透光板１８、制光体１９を、本体枠の鍔部１４ｎの内面に押え付けて係止させる。この際、係合部３０ａ２と小孔３２の位置が合わない場合には、軸支部３０ｂを溝１４ｑ内でスライドさせて調整する（図４（ｃ）の矢印ａ方向）。もう一方の弾性部材３０ａも同様に回動させて発光パネルＡの他端部を押え付けて係止させる。これにより、弾性部材３０ａの弾性力によって発光パネルＡが本体枠１４の内周側に配設された状態で確実に支持される。 Thereby, the light emission panel A, the translucent plate 18, and the light control body 19 are pressed and locked to the inner surface of the collar portion 14n of the main body frame by the elastic force of the wire. At this time, if the positions of the engaging portion 30a2 and the small hole 32 do not match, the shaft supporting portion 30b is adjusted by sliding in the groove 14q (in the direction of arrow a in FIG. 4C). The other elastic member 30a is also rotated in the same manner, and the other end portion of the light emitting panel A is pressed and locked. Thereby, the light emission panel A is reliably supported in the state arrange | positioned at the inner peripheral side of the main body frame 14 with the elastic force of the elastic member 30a.

また、支持部材３０は、その弾性部材３０ａが上記のように回動することによって、枠体１４ａ内に沈み込む寸法、すなわち、入り込む寸法ｄが回動に伴って連続して変わるので、発光パネルＡを本体枠１４に支持するときの高さを調整して支持することができる。すなわち、図４（ｂ）に示すように、制光体１９や透光板１８を設けない仕様の照明器具を構成する場合には、本体枠１４の光が放射される下方の開口部に対する発光パネルＡの高さが低くなった状態、換言すれば、枠体１４ａ内に発光パネルＡが深く入り込んだ状態になる。この状態で上記と同様に、弾性部材３０ａを回動させ先端の係合部３０ａ２を「低」の表示のある小孔３２に挿入して係合する。これにより、先端の係合部１３ａ２が枠体１４ａ内に深く沈み込み、ワイヤーの弾性力で上記同様の作用により確実に支持することができる。また、制光体１９を用いない仕様の照明器具の場合には、透光板１８と発光パネルＡのみを本体枠１４内に挿入し、弾性部材３０ａの係合部３０ａ２を「中」の表示のある小孔３２に挿入して係合する。 In addition, since the elastic member 30a rotates as described above, the support member 30 has a dimension that sinks into the frame body 14a, that is, the dimension d that enters the support member 30 continuously changes with the rotation. The height when A is supported by the main body frame 14 can be adjusted and supported. That is, as shown in FIG. 4B, when a lighting fixture having a specification in which the light control body 19 and the light transmitting plate 18 are not provided is configured, light emission to the lower opening from which the light of the main body frame 14 is emitted. In a state where the height of the panel A is lowered, in other words, the light emitting panel A is deeply inserted into the frame body 14a. In this state, similarly to the above, the elastic member 30a is rotated, and the engaging portion 30a2 at the tip is inserted into the small hole 32 with the indication “low” and engaged. As a result, the engaging portion 13a2 at the tip can sink deeply into the frame body 14a and can be reliably supported by the same action as described above by the elastic force of the wire. Further, in the case of a luminaire having a specification that does not use the light control member 19, only the light transmitting plate 18 and the light emitting panel A are inserted into the main body frame 14, and the engagement portion 30a2 of the elastic member 30a is displayed as “medium”. It is inserted into the small hole 32 with the engagement.

なお、弾性部材３０ａは、「高」の位置、すなわち、制光体１９、透光板１８および発光パネルＡが使用されて部品数が多くなり比較的重くなった状態でワイヤーが一番撓み反発力が強くなって強固に支持される。逆に「低」の位置、すなわち、発光パネルＡのみの比較的軽い状態では、ワイヤーの撓みが少なく回動操作もし易くなって、かつ適度な強さで支持することができる。 It should be noted that the elastic member 30a has the “high” position, that is, the wire is most bent and repelled in a state where the light control body 19, the light transmitting plate 18 and the light emitting panel A are used and the number of parts is relatively heavy. Strength is strongly supported. Conversely, in the “low” position, that is, in a relatively light state of only the light emitting panel A, the wire is less bent and can be easily rotated, and can be supported with an appropriate strength.

また、３個の小孔３２を本体枠１４の一辺に対して直交する方向に一直線状に設けたので、発光パネルＡの支持高さが変化してもバランスよく発光パネルＡを本体枠１４に取り付けることができる。さらに空洞部１１ｇと対向する位置に小孔３２を設けたので、係合部３０ａ２がＬＥＤ１１と干渉することがない。このように、小孔３２を設けることによって、バランスよく取り付けることができる位置を明確にし、支持する高さ寸法の変化に容易に対応することができる。なお、小孔３２は、係合部３２ａ２の回動軌道上に設けてもよく、この場合には、軸支部材３０ｂの位置を固定した状態で、支持部材３０を回動させて係合部３０ａ２と小孔３２とを係合させることによって発光パネルＡと本体枠１４とを取り付けることができる。つまり、支持する高さ寸法が変化しても軸支部材３０ｂの位置合わせが不要となる。 In addition, since the three small holes 32 are provided in a straight line in a direction orthogonal to one side of the main body frame 14, the light emitting panel A can be attached to the main body frame 14 in a balanced manner even if the support height of the light emitting panel A changes. Can be attached. Further, since the small hole 32 is provided at a position facing the hollow portion 11g, the engaging portion 30a2 does not interfere with the LED 11. Thus, by providing the small holes 32, it is possible to clarify the position where the attachment can be performed in a well-balanced manner and easily cope with the change in the height dimension to be supported. The small hole 32 may be provided on the rotation path of the engaging portion 32a2. In this case, the supporting member 30 is rotated in a state where the position of the shaft support member 30b is fixed. The light emitting panel A and the main body frame 14 can be attached by engaging the 30a2 with the small hole 32. That is, it is not necessary to align the shaft support member 30b even if the height dimension to be supported changes.

一方、上記に構成された本体枠１４には、前記係止片部１４ｄを形成した辺と対向する辺に、後述する支持枠１６に本体枠１４を係合させて支持する係合部１４ｅを形成する。係合部は図３（ｂ）（ｃ）に示すように、止め具１４ｅ１と軸受部１４ｅ２からなり、止め具は、一端にマイナス溝を形成したネジ頭１４ｅ３と、軸部の中間部に軸方向と直交する方向に突出させた短い凸部１４ｅ４と長いストッパー片１４ｅ５を一体に形成した金属棒で構成する。軸受部１４ｅ２は、本体枠１４の側板１４ｋに円筒状の軸受部１４ｅ２を一体に形成し、この軸受部を構成する円筒部に止め具の凸部１４ｅ４が嵌合する小孔１４ｅ６を形成する。 On the other hand, the main body frame 14 configured as described above has an engaging portion 14e for engaging and supporting the main body frame 14 with a support frame 16 to be described later on the side opposite to the side where the locking piece portion 14d is formed. Form. As shown in FIGS. 3B and 3C, the engaging portion includes a stopper 14e1 and a bearing portion 14e2, and the stopper includes a screw head 14e3 having a minus groove formed at one end, and a shaft at an intermediate portion of the shaft portion. A short convex portion 14e4 projecting in a direction perpendicular to the direction and a long stopper piece 14e5 are formed of a metal rod integrally formed. In the bearing portion 14e2, a cylindrical bearing portion 14e2 is integrally formed on the side plate 14k of the main body frame 14, and a small hole 14e6 into which the convex portion 14e4 of the stopper is fitted is formed in the cylindrical portion constituting the bearing portion.

上記に構成された止め具１４ｅ１の金属棒を本体枠１４の鍔部１４ｂに形成された貫通孔１４ｍを介して軸受部１４ｅ２に回動ができるように挿入する。これにより、ネジ頭１４ｅ３を回動することにより、ストッパー片１４ｅ５が本体枠１４の側面１４ｋから突出して、後述する支持枠１６の内方の鍔部１６ｂに内面から係合させることができる。このとき、ストッパー片１４ｅ５が突出して係合した状態で止め具１４ｅ１の凸部１４ｅ４が同時に回動する。この回動により軸受部１４ｅ２が樹脂の弾性を利用して撓みながら凸部１４ｅ４が円筒体の小孔１４ｅ６に嵌合して金属棒の回動が規制されロックされる。 The metal rod of the stopper 14e1 configured as described above is inserted into the bearing portion 14e2 through the through hole 14m formed in the flange portion 14b of the main body frame 14 so as to be rotatable. Thereby, by rotating the screw head 14e3, the stopper piece 14e5 protrudes from the side surface 14k of the main body frame 14, and can be engaged with the inner flange portion 16b of the support frame 16 described later from the inner surface. At this time, the convex portion 14e4 of the stopper 14e1 rotates simultaneously with the stopper piece 14e5 protruding and engaged. By this rotation, the bearing portion 14e2 is bent utilizing the elasticity of the resin, and the convex portion 14e4 is fitted into the small hole 14e6 of the cylindrical body, so that the rotation of the metal rod is restricted and locked.

次に、支持枠１６は、天井等の被設置部に設置されるもので、熱伝導性の良好な金属、本実施例では、本体枠１４と同様に白色に塗装したアルミニウムで正方形の枠体１６ａを一体に構成する。枠体１６ａの寸法は、枠内に上記構成の正方形の本体枠１４を内周側に配設して内包できる大きさに構成する。 Next, the support frame 16 is installed on an installation part such as a ceiling, and is a square frame made of a metal having good thermal conductivity, in this embodiment, aluminum coated in white like the main body frame 14. 16a is integrally formed. The size of the frame body 16a is set to a size that allows the square body frame 14 having the above-described configuration to be disposed inside the frame so as to be included.

支持枠１６には、枠体１６ａの内周に、内方に向けて突出する鍔部１６ｂが一体に形成され、この鍔部１６ｂの先端部に段部１６ｃ（図５（ａ））を一体に形成して、図中上方に開放する断面が略Ｕ字状の溝からなる係止受部１６ｄを、枠体１６ａの辺に沿って長く一体に形成する。この係止受部１６ｄは、正方形をなす支持枠１６の各辺、すなわち、四辺に全体に形成する。さらに、枠体１６ａの外方に向けて突出する飾り縁となる鍔部１６ｅを一体に形成する。 The support frame 16 is integrally formed with a flange portion 16b protruding inward on the inner periphery of the frame body 16a, and a step portion 16c (FIG. 5 (a)) is integrated with a tip portion of the flange portion 16b. A locking receiving portion 16d having a substantially U-shaped cross section that opens upward in the drawing is integrally formed along the side of the frame body 16a. The latch receiving portions 16d are formed on each side of the square support frame 16, that is, on all four sides. Furthermore, the flange part 16e used as the decoration edge which protrudes toward the outer side of the frame 16a is integrally formed.

上記係止受部１６ｄの溝には、上述した本体枠１４の係止片部１４ｄが嵌合され、この係止片部１４ｄと係止受部１６ｄにより本体枠１４が支持枠１６の一辺に対し回動、すなわち、開閉がなされるときのヒンジ部Ｃとしての作用（図５（ａ））と、本体枠１４が開放されたときに支持枠１６から外れないように係止する外れ防止の作用（図５（ｂ））を行う。なお、係止受部１６ｄは正方形をなす支持枠１６の四辺に形成されているので、どの辺の係止受部に対しても正方形の本体枠１４の係止片部１４ｄを係止させることができる。また、支持枠１６の対向する辺に位置する側板１６ｆに、鋼板からなる受片１６ｇを固着し、この受片の中央部にネジ孔１６ｈを形成する（図６（ｂ））。 The locking piece portion 14d of the main body frame 14 described above is fitted into the groove of the locking receiving portion 16d, and the main body frame 14 is fitted to one side of the support frame 16 by the locking piece portion 14d and the locking receiving portion 16d. The action as the hinge portion C when turning, that is, opening and closing (FIG. 5 (a)), and prevention of disengagement that prevents the main body frame 14 from being detached from the support frame 16 when it is opened. The action (FIG. 5B) is performed. Since the latch receiving portions 16d are formed on the four sides of the square support frame 16, the latch piece portions 14d of the square main body frame 14 are latched to the latch receiving portions on any side. Can do. Further, a receiving piece 16g made of a steel plate is fixed to a side plate 16f located on the opposite side of the support frame 16, and a screw hole 16h is formed in the central portion of the receiving piece (FIG. 6B).

点灯装置１７は、例えば、交流電圧１００Ｖを直流電圧２４Ｖに変換してＬＥＤ１１に供給する点灯回路（図示せず）で構成され、図６（ａ）に示すように、鋼板で構成された長い直方体からなるケース部材１７ａに点灯回路が内蔵され配設される。ケース部材１７ａの両端部に、側板１７ｃから上面板１７ｄにわたって支持孔が形成される。この支持孔は側板１７ｃに横長の大きな案内孔１７ｅが形成され、この案内孔に連続して上面板１７ｄに縦長の長孔１７ｆが形成されている。この案内孔１７ｅは後述する吊りボルト２０のナット２１が挿入でき、長孔１７ｆはボルト２０を挿入できるがナット２１は挿入できない寸法に形成する。また、ケース部材１７ａの両側板１７ｃには、案内孔１７ｅの下方に位置して取り付け用のネジ孔１７ｇを形成する。 The lighting device 17 is composed of, for example, a lighting circuit (not shown) that converts an AC voltage of 100 V into a DC voltage of 24 V and supplies the converted voltage to the LED 11, and as shown in FIG. 6A, a long rectangular parallelepiped made of a steel plate. A lighting circuit is built in and disposed in the case member 17a. Support holes are formed at both ends of the case member 17a from the side plate 17c to the upper surface plate 17d. The support hole is formed with a laterally large guide hole 17e in the side plate 17c, and a longitudinally long slot 17f is formed in the upper surface plate 17d in succession to the guide hole. The guide hole 17e can be inserted with a nut 21 of a suspension bolt 20, which will be described later, and the long hole 17f is formed with a dimension that allows the bolt 20 to be inserted but the nut 21 cannot be inserted. Further, screw holes 17g for attachment are formed on both side plates 17c of the case member 17a so as to be positioned below the guide holes 17e.

点灯回路を内蔵し配設したケース部材１７ａは支持枠１６に支持できるように構成される。すなわち、ケース部材１７ａを支持枠１６の対向する辺に位置する側板１６ｆに跨らせるようにして配置し、両方の側板１６ｆに固着された受片１６ｇのネジ孔１６ｈに、ケース部材１７ａの両側板１７ｃのネジ孔１７ｇを合致させてネジで固着できるように構成する。 The case member 17a having a built-in lighting circuit is configured to be supported by the support frame 16. That is, the case member 17a is arranged so as to straddle the side plates 16f located on the opposite sides of the support frame 16, and the screw holes 16h of the receiving pieces 16g fixed to both the side plates 16f are placed on both sides of the case member 17a. The screw holes 17g of the plate 17c are matched so that they can be fixed with screws.

また、ケース部材１７ａの一方の側板１７ｃからは、点灯回路の出力端に接続された端子部１７ｊが引き出され、発光パネルＡの入力端子に接続されたパネル側リード線ｗの先端に取付けられたコネクタ１２ｃが接続される（図７（ｂ））。この場合、ケース部材１７ａは支持枠１６へ取り付ける際に、端子部１７ｊが引き出された側板１７ｃが、換言すれば、端子部１７ｊが支持枠１６の溝状の係止受部１６ｄ近傍に面するように位置させて取り付ける。 Further, from one side plate 17c of the case member 17a, a terminal portion 17j connected to the output end of the lighting circuit is drawn out and attached to the tip of the panel side lead wire w connected to the input terminal of the light emitting panel A. The connector 12c is connected (FIG. 7B). In this case, when the case member 17 a is attached to the support frame 16, the side plate 17 c from which the terminal portion 17 j is pulled out, in other words, the terminal portion 17 j faces the vicinity of the groove-shaped locking receiving portion 16 d of the support frame 16. Position it so that it is attached.

上記に構成された発光パネルＡ、本体枠１４、支持枠１６および点灯装置１７からなる照明器具１０は、次のようにして、被設置部である天井面Ｘに設置されて使用される（図７）。なお、天井Ｘには、予め支持枠１６が挿入できる大きさの正方形の開口ｈを形成し、天井裏の支持材Ｘ１に２本の吊りボルト２０を設置しておく。２本の吊りボルトは、点灯装置１７のケース部材１７ａの両端部に形成した支持孔の間隔寸法に大体合わせた間隔で設置し、それぞれに２個ずつのナット２１、２１を装着しておく(図６（ａ）)。 The lighting fixture 10 composed of the light-emitting panel A, the main body frame 14, the support frame 16, and the lighting device 17 configured as described above is installed and used on the ceiling surface X that is an installation portion as follows (FIG. 7). Note that a square opening h having a size into which the support frame 16 can be inserted is formed in the ceiling X in advance, and two suspension bolts 20 are installed on the support material X1 on the back of the ceiling. The two suspension bolts are installed at intervals roughly matching the distance between the support holes formed at both ends of the case member 17a of the lighting device 17, and two nuts 21 and 21 are attached to each of the suspension bolts ( FIG. 6 (a)).

先ず、支持枠１６に点灯装置１７を、図６（ａ）に示すように予め支持しておく。次に、図７（ａ）に示すように、点灯装置のケース部材１７ａを支持した支持枠１６を、ケース部材１７ａを上方にして天井Ｘの開口ｈから天井内に挿入し、ケース部材１７ａの片方の支持孔、本実施例では図６（ａ）中左方の支持孔の案内孔１７ｅに、左方の吊りボルト２０のナット２１を挿入する。この際２個のナット２１の内、下方のナット２１を案内孔１７ｅに挿入し、ボルト２０を長孔１７ｆに挿通させる。上方のナット２１はケース部材１７ａの上面板１７ｄに面するようにしておく。同様に、右方の吊りボルト２０を撓ませて、下のナット２１を案内孔１７ｅ内に挿入し、さらにボルト２０を長孔１７ｆに挿通させる。 First, the lighting device 17 is supported in advance on the support frame 16 as shown in FIG. Next, as shown in FIG. 7A, the support frame 16 supporting the case member 17a of the lighting device is inserted into the ceiling through the opening h of the ceiling X with the case member 17a facing upward, and the case member 17a The nut 21 of the left suspension bolt 20 is inserted into one of the support holes, in this embodiment, the guide hole 17e of the left support hole in FIG. At this time, the lower nut 21 of the two nuts 21 is inserted into the guide hole 17e, and the bolt 20 is inserted into the elongated hole 17f. The upper nut 21 faces the upper surface plate 17d of the case member 17a. Similarly, the right suspension bolt 20 is bent, the lower nut 21 is inserted into the guide hole 17e, and the bolt 20 is further inserted through the long hole 17f.

この状態で、支持枠１６を開口ｈに合致させる。この際、ボルト２０をケース部材１７ａの長孔１７ｆ内で左右にスライドさせて支持枠１６の飾り縁となる鍔部１６ｅで開口ｈの周囲のギザギザ面が隠れるようにする。この状態で支持枠１６の天井Ｘに対する取付位置が決まる。この状態のまま、各吊りボルト２０の２個のナット２１をそれぞれ締め付けて、ケース部材１７ａを２本の吊りボルト２０に固着する。これにより、支持枠１６が点灯装置のケース部材１７ａを介して天井裏の支持材Ｘ１に固定される(図７（ａ）)。 In this state, the support frame 16 is aligned with the opening h. At this time, the bolt 20 is slid left and right within the elongated hole 17f of the case member 17a so that the knurled surface around the opening h is hidden by the flange portion 16e serving as a decorative edge of the support frame 16. In this state, the mounting position of the support frame 16 with respect to the ceiling X is determined. In this state, the two nuts 21 of each suspension bolt 20 are tightened to fix the case member 17a to the two suspension bolts 20. Thereby, the support frame 16 is fixed to the support material X1 on the back of the ceiling via the case member 17a of the lighting device (FIG. 7A).

この際、点灯装置１７は、支持枠１６に跨った状態に固定されるので、点灯装置の両側には開口部ａが形成され（図６（ａ））、この開口部から天井裏の状況および吊りボルト２０やナット２１などの状態を見ながら行う。また、天井面Ｘへの設置作業は、支持枠１６には発光パネルＡ等と本体枠１４が一体化された器具本体Ｂは取り付けられていない状態で、合成樹脂からなる軽い支持枠１６のみを持ち上げて設置する。 At this time, since the lighting device 17 is fixed in a state of straddling the support frame 16, openings a are formed on both sides of the lighting device (FIG. 6A). This is done while observing the state of the suspension bolt 20 and nut 21. Also, the installation work on the ceiling surface X is carried out by attaching only the light support frame 16 made of synthetic resin to the support frame 16 in a state in which the fixture main body B in which the light emitting panel A and the main body frame 14 are integrated is not attached. Lift and install.

次に、本体枠１４を持ち上げて本体枠１４の係止片部１４ｄを支持枠１６の内周に形成された係止受部１６ｄの溝に嵌合する。この際、係止受部１６ｄは正方形をなす支持枠１６の四辺に形成されているので、どの辺の係止受部１６ｄに対しても本体枠１４の係止片部１４ｄを係止させることができるので、天井近辺の障害物等の状況をみて、どの辺の係止受部に係止させるかを選定して決める。上記により、本体枠１４が支持枠１６の一辺に吊り下げられた状態で支持される(図７（ｂ）)。 Next, the main body frame 14 is lifted, and the locking piece portion 14 d of the main body frame 14 is fitted into the groove of the locking receiving portion 16 d formed on the inner periphery of the support frame 16. At this time, since the latch receiving portions 16d are formed on the four sides of the support frame 16 having a square shape, the latch piece 14d of the main body frame 14 is latched to the latch receiving portions 16d on any side. Therefore, by looking at the situation of obstacles near the ceiling, select and decide which side to be locked. As described above, the main body frame 14 is supported in a state of being suspended from one side of the support frame 16 (FIG. 7B).

次に、吊り下げられた状態の本体枠１４の枠体１４ａ内に、制光体１９、透光板１８、さらに発光パネルＡを順に挿入し、制光体１９を本体枠の鍔部１４ｎの内面に係止させる。次いで、支持部材３０の軸支部材３０ｂを枠体１４の対角線上に対向する角に近い位置の側板１４ｋの溝１４ｑに嵌め込み、弾性部材３０ａを枠体１４ａ側にワイヤーの弾性力に抗しながら回動し、「高」の表示のされた小孔３２に先端の係合部３０ａ２を挿入して係合させる。この際、係合部３０ａ２と小孔３２の位置が合わない場合には、軸支部３０ｂを溝１４ｑ内でスライドさせて調整する。さらに、もう一方の弾性部材３０ａも同様に回動させて発光パネルＡの他端部を押え付けて係止させ、発光パネルＡを本体枠１４の内周側に配設した状態に支持する（図７（ｂ））。 Next, the light control body 19, the translucent plate 18, and the light emitting panel A are sequentially inserted into the frame body 14a of the main body frame 14 in the suspended state, and the light control body 19 is inserted into the body frame flange 14n. Lock to the inner surface. Next, the shaft support member 30b of the support member 30 is fitted into the groove 14q of the side plate 14k at a position close to the diagonal opposite to the diagonal of the frame body 14, and the elastic member 30a is opposed to the elastic force of the wire on the frame body 14a side. It rotates, and the engaging portion 30a2 at the tip is inserted into and engaged with the small hole 32 marked “high”. At this time, if the positions of the engaging portion 30a2 and the small hole 32 do not match, the shaft supporting portion 30b is adjusted by sliding in the groove 14q. Further, the other elastic member 30a is similarly rotated to press and lock the other end portion of the light emitting panel A, thereby supporting the light emitting panel A in a state of being disposed on the inner peripheral side of the main body frame 14 ( FIG. 7B).

次に、点灯装置１７のケース部材１７ａの一方の側板１７ｃから引き出された端子部１７ｊに発光パネルＡ側のリード線ｗのコネクタ１２ｃを接続する。なお、この際、点灯装置１７と発光パネルＡとの配線接続がヒンジＣ側で行えるため発光パネル側リード線ｗは短いものでよい。これら作業は、本体枠１４が、支持枠１６から出され垂下された状態で行うことができ、見やすくなって施工性がよくなる。 Next, the connector 12c of the lead wire w on the light emitting panel A side is connected to the terminal portion 17j drawn out from one side plate 17c of the case member 17a of the lighting device 17. At this time, since the wiring connection between the lighting device 17 and the light emitting panel A can be performed on the hinge C side, the light emitting panel side lead wire w may be short. These operations can be performed in a state in which the main body frame 14 is extended from the support frame 16 and is suspended, which makes it easy to see and improves the workability.

上記により、係止片部１４ｄを係止受部１６ｄに係止した状態でヒンジ部Ｃが構成されるので、本体枠１４の係止片部１４ｄを、係止受部１６ｄを軸心として回動させる。すなわち、発光パネルＡ等と一体化された本体枠１４を、支持枠１６の一辺に係止した状態で、支持枠１６の中に本体枠１４を挿入するようにして、換言すれば、発光パネルＡで支持枠１６の開口を閉じるように押し上げて回動させる（図７（ｂ）の矢印方向）。 As described above, since the hinge portion C is configured in a state where the locking piece portion 14d is locked to the locking receiving portion 16d, the locking piece portion 14d of the main body frame 14 is rotated around the locking receiving portion 16d as an axis. Move. That is, the main body frame 14 integrated with the light emitting panel A or the like is locked to one side of the support frame 16 so that the main body frame 14 is inserted into the support frame 16, in other words, the light emitting panel. A is pushed up and closed so as to close the opening of the support frame 16 at A (in the direction of the arrow in FIG. 7B).

これにより、本体枠１４に係止された側と反対側の辺に設けられた係合部１４ｅが、支持枠１６の鍔部１６ｂに当接する。この状態で、図３（ｂ）（ｃ）に示すように、本体枠１４の表面に露出している止め具１４ｅ１のネジ頭１４ｅ３を、マイナスドライバを使って左右どちらかへ回動させストッパー片１４ｅ５を本体枠１４の側面１４ｋから突出させ、支持枠１６の鍔部１６ｂに内面から係合させる。これにより、本体枠１４の一辺が係止片部１４ｄと支持枠１６の係止受部１６ｄの嵌合により、他の辺が係合部１４ｅで係合されて支持される。 Thereby, the engaging portion 14 e provided on the side opposite to the side locked by the main body frame 14 abuts on the flange portion 16 b of the support frame 16. In this state, as shown in FIGS. 3B and 3C, the screw head 14e3 of the stopper 14e1 exposed on the surface of the main body frame 14 is rotated to the left or right using a flat-blade screwdriver. 14e5 is protruded from the side surface 14k of the main body frame 14, and is engaged with the flange portion 16b of the support frame 16 from the inner surface. Thereby, one side of the main body frame 14 is engaged and supported by the engaging portion 14e by fitting the locking piece portion 14d and the locking receiving portion 16d of the support frame 16 together.

この際、止め具１４ｅ１の凸部１４ｅ４が、円筒部の小孔１４ｅ６に嵌合して金属棒の回動が規制され、振動や長期間の使用などでストッパー片１４ｅ５が緩んで回り、支持枠１６の鍔部１６ｂ内面との係合が外れることがなく、発光パネルＡを確実に支持枠１６に係合させることができ、落下等の虞に対する安全性を保持している。 At this time, the convex portion 14e4 of the stopper 14e1 is fitted into the small hole 14e6 of the cylindrical portion to restrict the rotation of the metal rod, and the stopper piece 14e5 is loosened and rotated due to vibration or long-term use. The light emitting panel A can be reliably engaged with the support frame 16 without being disengaged from the inner surface of the flange portion 16b of the 16 so as to maintain safety against the possibility of dropping or the like.

上記により、発光パネルＡ、本体枠１４、支持枠１６および点灯装置１７からなる照明器具１０が天井Ｘに設置される。天井の開口ｈは、支持枠１６の飾り縁となる鍔部１６ｅで覆われ、この鍔部１６ｅと本体枠１４の鍔部１４ｂが面一となって天井面Ｘにフラットな状態で綺麗に設置され外観上もよくなる。 As described above, the lighting fixture 10 including the light-emitting panel A, the main body frame 14, the support frame 16, and the lighting device 17 is installed on the ceiling X. The opening h of the ceiling is covered with a collar 16e which is a decorative edge of the support frame 16, and the collar 16e and the collar 14b of the main body frame 14 are flush with each other so that the ceiling surface X is installed in a flat state. The appearance is also improved.

上記に設置された照明器具１０を点灯すると、発光パネルＡのＬＥＤ１１が白色に発光する。ＬＥＤから放射される光は下方および側方に向かって放射され反射体１１ｃの反射面１１ｈで反射され器具直下を含む周辺一帯を照射する広い略円形状の配光をもった照明を行う。同時に、反射面１１ｈで反射された光の一部が器具の側方に向けて放射され、天井面Ｘをより広範囲にわたって照射する。 When the lighting fixture 10 installed above is turned on, the LED 11 of the light emitting panel A emits white light. The light emitted from the LEDs is emitted downward and laterally, reflected by the reflecting surface 11h of the reflector 11c, and illuminated with a wide, substantially circular light distribution that irradiates the entire surrounding area including directly under the fixture. At the same time, a part of the light reflected by the reflecting surface 11h is emitted toward the side of the appliance, and irradiates the ceiling surface X over a wider range.

また、点灯時に各ＬＥＤ１１から発生する熱は、基体１１ａから鋼板製の放熱板１１ｊを介して外部に放熱される。また、点灯装置１７の熱も鋼板からなるケース部材１７ａやアルミニウムからなる本体枠１４を介して放熱される。これにより、ＬＥＤの発光効率の低下を防止することができ、温度上昇に伴う光束の低下を防止することができると共に、ＬＥＤの長寿命化を図ることが可能となる。また点灯装置１７の回路部品の信頼性も高めることができる。 Further, the heat generated from each LED 11 at the time of lighting is radiated to the outside from the base 11a through the steel plate heat radiating plate 11j. Further, the heat of the lighting device 17 is also radiated through the case member 17a made of a steel plate and the main body frame 14 made of aluminum. As a result, the light emission efficiency of the LED can be prevented from being lowered, the light flux can be prevented from being lowered due to the temperature rise, and the life of the LED can be extended. In addition, the reliability of the circuit components of the lighting device 17 can be improved.

次に、光源となるＬＥＤ等のメンテナンスなどで発光パネルＡを取り出す場合には、次のようにして取り外す。先ず、図３（ｂ）（ｃ）に示すように、本体枠１４の表面に露出している止め具１４ｅ１のネジ頭１４ｅ３を、マイナスドライバを使って左右どちらかへ回動させストッパー片１４ｅ５と支持枠１６の鍔部１６ｂ内面との係合を解除する。この際、止め具１４ｅ１の凸部１４ｅ４が同時に回動する。この回動により軸受部１４ｅ２が樹脂の弾性を利用して撓みながら凸部１４ｅ４が円筒体の小孔１４ｅ６から外れてロックが解除される。 Next, when taking out the light emission panel A by maintenance etc. of LED etc. which become a light source, it removes as follows. First, as shown in FIGS. 3B and 3C, the screw head 14e3 of the stopper 14e1 exposed on the surface of the main body frame 14 is rotated left or right using a flat-blade screwdriver, and the stopper piece 14e5 and The engagement with the inner surface of the flange 16b of the support frame 16 is released. At this time, the convex portion 14e4 of the stopper 14e1 rotates simultaneously. By this rotation, the bearing portion 14e2 is bent utilizing the elasticity of the resin, and the convex portion 14e4 is released from the small hole 14e6 of the cylindrical body, and the lock is released.

この状態で、本体枠１４の係止片部１４ｄを、支持枠１６の係止受部１６ｄを軸心として回動させ、支持枠１６の開口から本体枠１４を開くようにして回動させる（図５（ａ）→（ｂ））。これにより、係止受部１６ｄの溝に本体枠１４の鉤状の係止片部１４ｄが係止する。これにより、本体枠１４が開放された状態で支持枠１６から外れないように係止され吊り下げられた状態になる（図７（ｂ））。 In this state, the locking piece portion 14d of the main body frame 14 is rotated about the locking receiving portion 16d of the support frame 16 as an axis, and is rotated so as to open the main body frame 14 from the opening of the support frame 16 ( FIG. 5 (a) → (b)). Thereby, the hook-shaped locking piece portion 14d of the main body frame 14 is locked in the groove of the locking receiving portion 16d. Thus, the main body frame 14 is locked and suspended so as not to be detached from the support frame 16 in the opened state (FIG. 7B).

この状態で、発光パネルＡを本体枠１４に支持している支持部材３０の弾性部材３０ａを、その係合部３０ａ２を小孔３２から引き抜き、先端の係合部３０ａ２を本体枠１４の枠体１４ａ内から出るように回動させて発光パネルＡの上面から外し、発光パネルＡを本体枠１４から引き出せばよい。また、本体枠１４と一緒に発光パネルを取り外す場合には、図５（ｃ）に示すように、係止受部１６ｄの溝と本体枠１４の鉤状の係止片部１４ｄとが係止した状態から、さらに開く方向に回動させて鉤状の係止片部１４ｄと係止受部１６ｄの溝との係止状態を解除すれば、本体枠１４を発光パネルＡと共に、すなわち、器具本体Ｂを支持枠１６から取り外すことができる。 In this state, the elastic member 30a of the support member 30 that supports the light emitting panel A on the main body frame 14 is pulled out of the engaging portion 30a2 from the small hole 32, and the engaging portion 30a2 at the tip is the frame body of the main body frame 14. The light-emitting panel A may be pulled out from the upper surface of the light-emitting panel A by being rotated so as to come out of the light-emitting panel 14 a, and the light-emitting panel A is pulled out from the main body frame 14. When the light emitting panel is removed together with the main body frame 14, as shown in FIG. 5C, the groove of the locking receiving portion 16d and the hook-shaped locking piece portion 14d of the main body frame 14 are locked. From this state, the main body frame 14 together with the light-emitting panel A, that is, the instrument, is released by further rotating in the opening direction to release the locking state between the hook-shaped locking piece portion 14d and the groove of the locking receiving portion 16d. The main body B can be removed from the support frame 16.

以上、本実施例によれば、一辺に鉤状に突出する係止片部１４ｄを形成した本体枠１４と、正方形をなす各辺に本体枠１４の係止片部１４ｄを嵌合する溝状の係止受部１６ｄを形成した支持枠１６を構成したので、軽い支持枠１６のみを天井Ｘに先ず設置することができ、枠体１６ａをなし開放した支持枠１６から天井裏の状況や吊りボルト２０やナット２１などの状態を見ながら行うことができ施工がし易くなる。 As described above, according to the present embodiment, the main body frame 14 formed with the locking piece portion 14d protruding in a hook shape on one side, and the groove shape for fitting the locking piece portion 14d of the main body frame 14 on each side forming a square. Since the support frame 16 in which the latch receiving portion 16d is formed is configured, only the light support frame 16 can be first installed on the ceiling X. This can be done while looking at the state of the bolts 20 and nuts 21 and the like, making the installation easier.

また、支持枠１６を先に天井Ｘに設置し、本体枠１４の係止片部１４ｄを、既に設置された支持枠１６の係止受部１６ｄに嵌合し本体枠１４を支持枠１６に取り付け、その状態で本体枠１４に発光パネルＡを取り付けるようにすることができ、天井面Ｘへの設置作業は、支持枠１６には発光パネルＡと本体枠１４が一体化された器具本体Ｂは取り付けられていない状態で、合成樹脂からなる軽い支持枠１６のみを持ち上げて設置すればよく、従来のように、点灯装置など比較的重いものを支えながらの作業となることがなく施工が一層し易くなり、これら作用により天井等の被設置部への施工性を一層容易にすることができる。特に、光源としてＬＥＤを採用し、軽量化を図った照明器具において、本体の軽量化と合わせて、施工性に一層優れた照明器具を提供することができる。 Further, the support frame 16 is first installed on the ceiling X, and the locking piece portion 14d of the main body frame 14 is fitted to the locking receiving portion 16d of the support frame 16 that has already been installed, so that the main body frame 14 is attached to the support frame 16. In this state, the light emitting panel A can be attached to the main body frame 14, and the installation work on the ceiling surface X is performed by the support frame 16 in which the light emitting panel A and the main body frame 14 are integrated. It is only necessary to lift and install the light support frame 16 made of a synthetic resin without attaching it, and it is possible to perform construction without supporting a relatively heavy object such as a lighting device as in the prior art. It becomes easy to carry out, and the workability to to-be-installed parts, such as a ceiling, can be made still easier by these effects. In particular, in a lighting fixture that employs an LED as a light source and is reduced in weight, it is possible to provide a lighting fixture that is more excellent in workability in combination with the weight reduction of the main body.

また、支持枠１６の係止受部１６ｄは正方形をなす支持枠１６の四辺に形成されているので、どの辺の係止受部に対しても正方形の本体枠１４の係止片部１４ｄを係止させることができるので、天井近辺の障害物等の状況をみて、本体枠１４が支持枠１６に対して開閉ができるかなどを判断しながら、どの辺の係止受部１６ｄに本体枠１４の係止片部１４ｄを嵌合させるかを選定して決めることができ、さらに、施工性に富んだ照明器具を提供することができる。同時に設置後のメンテナンス等で器具本体Ｂが天井面Ｘの障害物などに当たり取り外せなくなるようなことを防ぐことができる。また、係止片部１４ｄおよび係止受部１６ｄは、一辺に沿って長く形成されており、両者を確実に嵌合させることができるので、確実なヒンジ部Ｃを構成することができ、本体枠１４の開閉の際の操作性もよく、またガタツキ等が生じない。また、長い係止片部１４ｄおよび係止受部１６ｄにより本体枠１４と支持枠１６との隙間を隠すことができ外観的にも良好になる。 Further, since the latch receiving portions 16d of the support frame 16 are formed on the four sides of the square support frame 16, the latch piece portions 14d of the square main body frame 14 are connected to the latch receiving portions on any side. Since it can be locked, the state of the obstacle near the ceiling, etc., and determining whether the main body frame 14 can be opened and closed with respect to the support frame 16, etc. It is possible to select and determine whether or not the 14 locking piece portions 14d are to be fitted, and it is possible to provide a lighting fixture with excellent workability. At the same time, it is possible to prevent the instrument body B from hitting an obstacle on the ceiling surface X and being unable to be removed due to maintenance after installation. Moreover, since the latching piece part 14d and the latching receiving part 16d are formed long along one side and can fit both together reliably, the reliable hinge part C can be comprised, The operability at the time of opening and closing the frame 14 is good, and rattling or the like does not occur. Further, the gap between the main body frame 14 and the support frame 16 can be hidden by the long locking piece portion 14d and the locking receiving portion 16d, and the appearance is also improved.

また、発光パネルＡと本体枠１４は、弾性部材３０ａからなる支持部材３０によって、弾性部材３０ａを回動させることにより押圧して支持するようにしたので、施工は簡単な回動操作で行うことができると共に、弾性力によって確実に支持することができ、高所や暗がりにおける施工を一層容易にし、かつ確実に行うことができる。 Further, since the light emitting panel A and the main body frame 14 are pressed and supported by rotating the elastic member 30a by the support member 30 made of the elastic member 30a, the construction is performed by a simple rotation operation. In addition, it can be reliably supported by the elastic force, making it easier and more reliable to perform construction in high places or in the dark.

また、支持部材３０は、本体枠１４の軸心方向ｘ−ｘに対し傾斜して回動可能に支持したので、弾性部材３０ａが回動することによって、枠体１４ａ内に沈み込む寸法が回動に伴って連続して変り、発光パネルＡを本体枠１４に支持するときの高さを調整して支持することができ、各種仕様の照明器具に対しても確実に発光パネルＡを本体枠１４に支持することができ、仕様が変わっても同様の施工手順、方法で簡単に行うことができる。同時に、弾性部材３０ａは、回動によってワイヤーの撓みが変わり押え付ける力を調整することができるので、支持する発光パネルＡや制光体１９等の重さに対応した力で支持することができ、一層確実にかつ強固に支持することができる。また、回動する度合いによって回動操作時の力（ワイヤーの反発力）も調整することができ操作もし易くなる。また、弾性部材３０ａを枠体１４ａ側にワイヤーの弾性力に抗しながら回動する際に、先端の係合部３０ａ２が本体枠１４の縁に掛かることなく乗り越えることができるので一層操作がし易くなる。また、支持部材３０は、本体枠１４の側板１４ｋの溝１４ｑに対して支持する位置が選択できるように、スライド可能に設けたので、施工に際しては予め決められた所定の位置を狙って設ける必要がなく一層操作が容易になる。 In addition, since the support member 30 is tilted with respect to the axial direction xx of the main body frame 14 and supported so as to be rotatable, the elastic member 30a is rotated so that the dimension sinking into the frame body 14a is reduced. The height changes when the light-emitting panel A is supported on the main body frame 14 and can be supported by the movement, and the light-emitting panel A can be securely attached to lighting fixtures of various specifications. 14, even if the specifications change, it can be easily performed by the same construction procedure and method. At the same time, the elastic member 30a can be supported by a force corresponding to the weight of the light-emitting panel A and the light control body 19 to be supported because the bending of the wire changes and can be adjusted by turning. Thus, it can be supported more securely and firmly. Moreover, the force (repulsive force of the wire) at the time of the rotation operation can be adjusted depending on the degree of rotation, and the operation becomes easy. Further, when the elastic member 30a is rotated toward the frame body 14a while resisting the elastic force of the wire, the engagement portion 30a2 at the tip can be overcome without being caught on the edge of the main body frame 14, so that the operation is further performed. It becomes easy. Further, since the support member 30 is slidably provided so that a position to be supported with respect to the groove 14q of the side plate 14k of the main body frame 14 can be selected, it is necessary to provide a predetermined position at the time of construction. The operation becomes easier.

また、位置決め手段３２を設けたので、例えば、「高」「中」「低」等の高さ表示にしたがって支持部材３０の係合部３０ａ２を係合すればよく、一層施工性がよくなり、かつ、振動や長期間の使用にわたり係合部が緩んだり外れたりすることがなく、確実に発光パネルＡ本体枠１４に支持することができる。しかも、位置決め手段３２は、発光パネルＡの放熱板１１ｊに単に複数個の小孔を形成する簡易な構造で構成することができコスト的にも有利となる。位置決め手段を構成する複数の小孔３２は、反射体１１ｃの空洞部１１ｇ内に基板１１ａを貫通させて形成したので、ＬＥＤ１１と干渉することなくデッドスペースを有効に利用することができる。また、支持部材３０は、本体枠１４の側板１４ｋの溝１４ｑに対して自由にスライドができ、位置調整をできるように設けたので、上記位置決め手段の機能と相まってより簡単に位置合わせを行うことができる。 Further, since the positioning means 32 is provided, for example, it is only necessary to engage the engaging portion 30a2 of the support member 30 according to the height indication such as “high”, “medium”, “low”, and the workability is further improved. In addition, the engaging portion does not loosen or come off over vibration or long-term use, and can be reliably supported on the light-emitting panel A main body frame 14. Moreover, the positioning means 32 can be configured with a simple structure in which a plurality of small holes are simply formed in the heat radiating plate 11j of the light emitting panel A, which is advantageous in terms of cost. Since the plurality of small holes 32 constituting the positioning means are formed by penetrating the substrate 11a in the hollow portion 11g of the reflector 11c, the dead space can be effectively used without interfering with the LED 11. Further, since the support member 30 is provided so as to be freely slidable with respect to the groove 14q of the side plate 14k of the main body frame 14 and to be able to adjust the position, the alignment can be performed more easily in combination with the function of the positioning means. Can do.

以上、本実施例において、支持枠１６の係止受部１６ｄは、支持枠１６の四辺全てに形成したが、係合部１４ｅである止め具１４ｅ１と対向する辺にのみ形成するようにしてもよい。係止受部１６ｄおよび係止片部１４ｄを、辺に沿って長く形成したが、いずれか一方、若しくは両方を辺の長さより短く形成するようにしてもよい。本体枠１４および支持枠１６は、熱伝導性の良好な金属で構成したが、耐熱性、耐候性で電気絶縁性を有する合成樹脂、例えば、ＰＢＴ（ポリブチレンテレフタレート）などで構成してもよい。 As described above, in the present embodiment, the locking receiving portions 16d of the support frame 16 are formed on all four sides of the support frame 16, but may be formed only on the side facing the stopper 14e1 that is the engaging portion 14e. Good. Although the locking receiving portion 16d and the locking piece portion 14d are formed long along the side, either one or both may be formed shorter than the length of the side. The main body frame 14 and the support frame 16 are made of a metal having good thermal conductivity, but may be made of a synthetic resin having heat resistance, weather resistance and electrical insulation, for example, PBT (polybutylene terephthalate). .

また、支持部材３０の弾性部材３０ａは、位置決め手段である小孔を使用しないで、任意の位置で押え付けるようにしてもよく、さらに、支持部材３０を本体枠１４の側板１４ｋの所定の位置に固定して設けるように構成してもよい。発光パネルＡの高さを調整する手段は、上述した制光体１９や透光板１８を発光パネルＡと本体枠１４との間に介在させて行うことが好ましいが、本体枠１４の枠体１４ａ内に内包できる寸法の枠体からなる各種の高さを有する専用のスペーサを別途に構成して行うようにしてもよい。 In addition, the elastic member 30a of the support member 30 may be pressed at an arbitrary position without using a small hole as a positioning means, and the support member 30 may be pressed at a predetermined position on the side plate 14k of the main body frame 14. You may comprise so that it may provide fixed to. The means for adjusting the height of the light emitting panel A is preferably performed by interposing the light control body 19 and the light transmitting plate 18 described above between the light emitting panel A and the main body frame 14. A dedicated spacer having various heights made of a frame having a size that can be included in 14a may be separately configured.

また、本発明は、天井などの被設置面に埋め込まれて設置される照明器具を構成したが、天井に直付けされて設置される照明器具であってもよい。以上、本発明の好適な実施形態を説明したが、本発明は上述の各実施例に限定されることなく、本発明の要旨を逸脱しない範囲内において、種々の設計変更を行うことができる。 Moreover, although this invention comprised the lighting fixture installed by being embedded in to-be-installed surfaces, such as a ceiling, the lighting fixture directly attached to a ceiling and installed may be sufficient.
