The power supply line inserted through the insertion hole 120 is electrically connected to the terminal block 13 fixed to the lower surface of the base plate 12. In the terminal block 13, one end of an electric wire is connected to a connection portion (not shown). Then, the other end of the electric wire is electrically connected to the power supply device 7 (see FIG. 4). Therefore, AC power is supplied from an external power source (commercial AC power source or the like) to the power supply device 7 via the terminal block 13. Further, the base plate 12 is provided with a plurality of bolt insertion holes 121 (two not shown) into which suspension bolts (not shown) are inserted, arranged in a row in the left-right direction (see FIG. 2). Further, two so-called latches 14 are attached to both front and rear sides of the frame 11 at intervals in the left-right direction. However, in FIG. 2, only the two rear latches 14 are shown. Then, as will be described later, the light source unit 2 is attached to the main body 10 by these four latches 14. Further, a hook hole 110 formed of a square hole is provided on the left side surface of the frame body 11 (see FIG. 2).

３つの光源モジュール３は全て同じ構成を有しているので、１つの光源モジュール３について説明する。光源モジュール３は、図３に示すように、長尺の基板３０と、基板３０の表面（下面）に実装されている複数の固体光源と、コネクタ３２とを有している。複数の固体光源はそれぞれ、白色光を放射する発光ダイオード（ＬＥＤ：Light Emitting Diode）３１である。これら複数のＬＥＤ３１は、基板３０の下面において、基板３０の長手方向（前後方向）に沿って等間隔かつ２列に並ぶように配置されて実装されている。また、基板３０の下面における前端にコネクタ３２が実装されている。コネクタ３２は、基板３０の下面に形成されている導体（銅はく）を介して、複数のＬＥＤ３１のそれぞれと電気的に接続されている。なお、コネクタ３２は、電線の先端に設けられているプラグと抜き差し可能に接続される。電線は、電源装置７と電気的に接続されている。電源装置７から出力される直流電流が電線を介して光源モジュール３に供給される。 Since all three light source modules 3 have the same configuration, one light source module 3 will be described. As shown in FIG. 3, the light source module 3 has a long substrate 30, a plurality of solid-state light sources mounted on the surface (lower surface) of the substrate 30, and a connector 32. Each of the plurality of solid-state light sources is a light emitting diode (LED) 31 that emits white light. These plurality of LEDs 31 are mounted on the lower surface of the substrate 30 so as to be arranged in two rows at equal intervals along the longitudinal direction (front-back direction) of the substrate 30. Further, the connector 32 is mounted on the front end of the lower surface of the substrate 30. The connector 32 is electrically connected to each of the plurality of LEDs 31 via a conductor (copper foil) formed on the lower surface of the substrate 30. The connector 32 is removably connected to a plug provided at the tip of the electric wire. The electric wire is electrically connected to the power supply device 7. The direct current output from the power supply device 7 is supplied to the light source module 3 via the electric wire.

３つの光源モジュール３はそれぞれ、基板３０の長手方向を取付板６の前後方向に一致させ、取付板６の左右方向に等間隔に並んだ状態で取付板６の下面に取り付けられている（図３参照）。より詳細には、基板３０は、厚み方向（上下方向）に貫通する複数（６つ）の取付孔３３を有している。これら６つの取付孔３３のうちの３つの取付孔３３が、基板３０の長手方向（前後方向）に沿って等間隔に並ぶように、基板３０の右端に配置されている。また、６つの取付孔３３のうちの残り３つの取付孔３３が、基板３０の長手方向（前後方向）に沿って等間隔に並ぶように、基板３０の左端に配置されている。なお、これら６つの取付孔３３は角孔からなり、長手方向を基板３０の長手方向に一致させる向きに設けられている（図３参照）。そして、これらの取付孔３３のそれぞれに、取付板６に設けられている複数の取付部６０が１つずつ挿通されている。複数の取付部６０はそれぞれ、取付板６が鈎形に切り起こされて形成されている。基板３０は、６つの取付孔３３のそれぞれに取付部６０が１つずつ挿通された状態で、（基板３０の）長手方向（前後方向）に移動させられることにより、複数の取付部６０のそれぞれと取付板６の間に挟まれて取付板６に取り付けられている（図３参照）。 Each of the three light source modules 3 is mounted on the lower surface of the mounting plate 6 in a state where the longitudinal direction of the substrate 30 is aligned with the front-rear direction of the mounting plate 6 and the three light source modules 3 are arranged at equal intervals in the left-right direction of the mounting plate 6 (FIG. 3). More specifically, the substrate 30 has a plurality (six) mounting holes 33 penetrating in the thickness direction (vertical direction). Three of the six mounting holes 33 are arranged at the right end of the substrate 30 so as to be arranged at equal intervals along the longitudinal direction (front-back direction) of the substrate 30. Further, the remaining three mounting holes 33 out of the six mounting holes 33 are arranged at the left end of the substrate 30 so as to be arranged at equal intervals along the longitudinal direction (front-back direction) of the substrate 30. The six mounting holes 33 are square holes and are provided so that the longitudinal direction coincides with the longitudinal direction of the substrate 30 (see FIG. 3). A plurality of mounting portions 60 provided on the mounting plate 6 are inserted into each of these mounting holes 33 one by one. Each of the plurality of mounting portions 60 is formed by cutting up the mounting plate 6 into a hook shape. The board 30 is moved in the longitudinal direction (front-back direction) (of the board 30) with one mounting portion 60 inserted into each of the six mounting holes 33, so that each of the plurality of mounting portions 60 is moved.

Further, each of the pair of mounting claws 513 faces the upper surface of the corresponding base portion 511 of the pair of base portions 511 and forms a gap between the pair of mounting claws 513 and the upper surface of the corresponding base portion 511. Each of the pair of holding portions 514 is formed in a band shape. Further, each of the pair of pressing portions 514 projects from the lower surface of the corresponding base portion 511 in the thickness direction (front-rear direction) of the main wall portion 510.

カバーエンド５１は、一対の取付爪５１３によって取付板６に取り付けられている。より詳細には、一対の取付爪５１３のそれぞれと、対応するベース部５１１の上面との間の隙間に取付板６が差し込まれることにより、カバーエンド５１が取付板６に取り付けられている（図３及び図４参照）。なお、一つのカバーエンド５１のそれぞれの周壁部５１２は、カバー本体５０の長手方向（前後方向）の端部とかん合されている（図３参照）。 The cover end 51 is attached to the mounting plate 6 by a pair of mounting claws 513. More specifically, the cover end 51 is attached to the mounting plate 6 by inserting the mounting plate 6 into the gap between each of the pair of mounting claws 513 and the upper surface of the corresponding base portion 511 (FIG. FIG. 3 and FIG. 4). Each peripheral wall portion 512 of one cover end 51 is entangled with an end portion of the cover main body 50 in the longitudinal direction (front-rear direction) (see FIG. 3).

２つのカバー部材４はそれぞれ、取付板６の下面において隣合う３つの光源モジュール３の間にそれぞれ生じる２箇所のスペースのうちの対応するスペース（第２領域）に配置される（図１〜図３参照）。つまり、カバー部材４は、取付板６の下面において光源（光源モジュール３及び透光カバー５）が取り付けられる領域（第１領域）を除く第２領域に取り付けられる。２つのカバー部材４はそれぞれ、カバー板４０と、複数（図示例では４つ）の第１取付部４１と、複数（図示例では２つ）の第２取付部４２とを有している。さらに、２つのカバー部材４はそれぞれ、一対の側板４３を有している。 Each of the two cover members 4 is arranged in the corresponding space (second region) of the two spaces generated between the three adjacent light source modules 3 on the lower surface of the mounting plate 6 (FIGS. 1 to 1). 3). That is, the cover member 4 is attached to the lower surface of the attachment plate 6 in a second region excluding the region (first region) to which the light source (light source module 3 and the translucent cover 5) is attached. Each of the two cover members 4 has a cover plate 40, a plurality of (four in the illustrated example) first mounting portions 41, and a plurality of (two in the illustrated example) second mounting portions 42. Further, each of the two cover members 4 has a pair of side plates 43.

カバー板４０は、長尺の矩形の金属板が長手方向に沿ってＶ字状に折り曲げられた形状に形成されている。一対の側板４３はそれぞれ、幅（上下方向に沿った幅）の狭い矩形板状に形成され、カバー板４０の左右両側の上端から上向きに突出している（図３参照）。 The cover plate 40 is formed in a shape in which a long rectangular metal plate is bent in a V shape along the longitudinal direction. Each of the pair of side plates 43 is formed in the shape of a rectangular plate having a narrow width (width along the vertical direction), and projects upward from the upper ends on both the left and right sides of the cover plate 40 (see FIG. 3).

４つの第１取付部４１はそれぞれ、側板４３よりも幅が広く、かつ、長手方向（前後方向）の寸法が短い矩形板状に形成されている。そして、４つの第１取付部４１のうちの２つの第１取付部４１はそれぞれ、カバー板４０の右側の上端における前後の両端近くから上向きに突出している（図３参照）。また、４つの第１取付部４１のうちの残り２つの第１取付部４１はそれぞれ、カバー板４０の左側の上端における前後の両端近くから上向きに突出している（図４参照）。 Each of the four first mounting portions 41 is formed in a rectangular plate shape having a width wider than that of the side plate 43 and a short dimension in the longitudinal direction (front-rear direction). Then, two of the four first mounting portions 41 project upward from near both front and rear ends at the upper end on the right side of the cover plate 40 (see FIG. 3). Further, the remaining two first mounting portions 41 of the four first mounting portions 41 project upward from near both front and rear ends at the upper left end of the cover plate 40 (see FIG. 4).

４つの第１取付部４１はそれぞれ、第１引掛孔４１０と、第２引掛孔４１１とを有している（図３〜図５参照）。第１引掛孔４１０は、上下方向の幅よりも前後方向の幅が広い角孔である。また、第２引掛孔４１１は、上下方向の幅よりも前後方向の幅が狭い角孔である。第１引掛孔４１０と第２引掛孔４１１とは、前後方向に並ぶように配置されている。これら４つの第１取付部４１はそれぞれ、４つの第１取付部４１に一対一に対応して設けられている挿通孔６５に挿通されている（図３〜図５参照）。 Each of the four first mounting portions 41 has a first hook hole 410 and a second hook hole 411 (see FIGS. 3 to 5). The first hook hole 410 is a square hole having a width wider in the front-rear direction than a width in the vertical direction. Further, the second hook hole 411 is a square hole whose width in the front-rear direction is narrower than the width in the vertical direction. The first hook hole 410 and the second hook hole 411 are arranged so as to be arranged in the front-rear direction. Each of these four first mounting portions 41 is inserted into an insertion hole 65 provided in a one-to-one correspondence with the four first mounting portions 41 (see FIGS. 3 to 5).

一方、取付板６は、複数（図示例では８つ）の挿通孔６５と、複数の挿通孔６５と一対一に対応する複数（図示例では８つ）の固定部６６（第１の被取付部）とを有している（図４参照）。８つの挿通孔６５はそれぞれ、左右方向の幅よりも前後方向の幅が広い角孔であり、取付板６を厚み方向（上下方向）に貫通している。なお、８つの挿通孔６５は、左右方向に沿って４列に並び、前後方向に沿って２列に並ぶように配置されている。８つの固定部６６はそれぞれ、取付板６から上向きに切り起こされて形成されている（図５参照）。つまり、８つの挿通孔６５はそれぞれ、対応する固定部６６が切り起こされた後に生じる孔で形成されている。また、８つの固定部６６はそれぞれ、第１固定爪６６０と、第２固定爪６６１とを有している。第１固定爪６６０は、台形状に形成されている（図５参照）。第１固定爪６６０は、固定部６６の上端から取付板６の上面と平行に突出している。第２固定爪６６１は、三角形状に形成されている（図５参照）。第２固定爪６６１は、固定部６６の側面から取付板６の上面と垂直に突出している。 On the other hand, the mounting plate 6 has a plurality of (8 in the illustrated example) insertion holes 65 and a plurality of (8 in the illustrated example) fixing portions 66 (first mounted) corresponding to the plurality of insertion holes 65 in a one-to-one manner. (See FIG. 4). Each of the eight insertion holes 65 is a square hole whose width in the front-rear direction is wider than the width in the left-right direction, and penetrates the mounting plate 6 in the thickness direction (vertical direction). The eight insertion holes 65 are arranged so as to be arranged in four rows along the left-right direction and in two rows along the front-rear direction. Each of the eight fixing portions 66 is formed by being cut upward from the mounting plate 6 (see FIG. 5). That is, each of the eight insertion holes 65 is formed by holes formed after the corresponding fixing portion 66 is cut and raised. Further, each of the eight fixing portions 66 has a first fixing claw 660 and a second fixing claw 661. The first fixed claw 660 is formed in a trapezoidal shape (see FIG. 5). The first fixing claw 660 projects from the upper end of the fixing portion 66 in parallel with the upper surface of the mounting plate 6. The second fixed claw 661 is formed in a triangular shape (see FIG. 5). The second fixing claw 661 projects from the side surface of the fixing portion 66 perpendicularly to the upper surface of the mounting plate 6.

第１取付部４１が取付板６の下面側から挿通孔６５に挿通されると、固定部６６が第１取付部４１に押されて撓んだ後、第１固定爪６６０が第１取付部４１の第１引掛孔４１０に挿通され、第２固定爪６６１が第１取付部４１の第２引掛孔４１１に挿通される。そして、第１固定爪６６０が第１引掛孔４１０の縁に引っ掛かり、第２固定爪６６１が第２引掛孔４１１の縁に引っ掛かることによって、第１取付部４１が固定部６６に固定される（図４及び図５参照）。 When the first mounting portion 41 is inserted into the insertion hole 65 from the lower surface side of the mounting plate 6, the fixing portion 66 is pushed by the first mounting portion 41 and bends, and then the first fixing claw 660 becomes the first mounting portion. It is inserted into the first hook hole 410 of 41, and the second fixing claw 661 is inserted into the second hook hole 411 of the first mounting portion 41. Then, the first fixing claw 660 is hooked on the edge of the first hook hole 410, and the second fixing claw 661 is hooked on the edge of the second hook hole 411, whereby the first mounting portion 41 is fixed to the fixing portion 66 ( (See FIGS. 4 and 5).

ここで、２つの第２取付部４２は、４つの第１取付部４１が４つの固定部６６に固定されていない（第１の被取付部に取り付けられていない）状態で取付板６の２つの第２の被取付部のうちの対応する第２の被取付部に取り付けられる（図６〜図８参照）。なお、第２の被取付部は、取付板６における挿通孔６５の縁及び挿通孔６５の周縁部分である。 Here, in the two second mounting portions 42, the mounting plate 6-2 is in a state where the four first mounting portions 41 are not fixed to the four fixing portions 66 (not attached to the first mounted portion). It is attached to the corresponding second attached portion of the two second attached portions (see FIGS. 6 to 8). The second attachment portion is the edge of the insertion hole 65 and the peripheral edge portion of the insertion hole 65 in the attachment plate 6.

各第２取付部４２は、カバー板４０の右端にある２つの第１取付部４１のうちの対応する第１取付部４１の上端から外向き（右向き）に突出している。第２取付部４２は、図５に示すように、引掛片４２０と規制片４２１とを有している。第２取付部４２のうちで引掛片４２０と規制片４２１を除く部分（以下、主部４２２と呼ぶ場合がある）が矩形平板状に形成されている。規制片４２１は、主部４２２の基端側（主部４２２の第１取付部４１との境界側）における前端から前方へ突出するように形成されている。ただし、規制片４２１の前端における基端側と反対側の角が面取りされている。引掛片４２０は、第２取付部４２の主部４２２の先端側における後端から後方へ突出するように形成されている。ただし、引掛片４２０の後端における基端側の隅の角が面取りされている。 Each second mounting portion 42 projects outward (to the right) from the upper end of the corresponding first mounting portion 41 of the two first mounting portions 41 at the right end of the cover plate 40. As shown in FIG. 5, the second mounting portion 42 has a hook piece 420 and a regulation piece 421. A portion of the second mounting portion 42 excluding the hooking piece 420 and the restricting piece 421 (hereinafter, may be referred to as a main portion 422) is formed in a rectangular flat plate shape. The regulation piece 421 is formed so as to project forward from the front end on the base end side of the main portion 422 (the boundary side of the main portion 422 with the first mounting portion 41). However, the corner of the front end of the regulation piece 421 opposite to the base end side is chamfered. The hook piece 420 is formed so as to project rearward from the rear end on the front end side of the main portion 422 of the second mounting portion 42. However, the corners on the base end side at the rear end of the hook piece 420 are chamfered.

ここで、第２取付部４２の長さ寸法と取付板６の挿通孔６５の長さ寸法との関係について、図９Ａ及び図９Ｂを参照して説明する。挿通孔６５の長手方向（前後方向）の長さをＬ１とする。第２取付部４２の長手方向において主部４２２の後端（図９Ａ及び図９Ｂにおける左端）から規制片４２１の前端（図９Ａ及び図９Ｂにおける右端）までの長さをＬ２とする。第２取付部４２の長手方向において主部４２２の前端（図９Ａ及び図９Ｂにおける右端）から引掛片４２０の後端（図９Ａ及び図９Ｂにおける左端）までの長さをＬ３とする。第２取付部４２の長手方向において規制片４２１の前端から引掛片４２０の後端までの長さをＬ４とする。第２取付部４２の２つの長さＬ２とＬ３は等しく、かつ、これらの長さＬ２、Ｌ３は、挿通孔６５の長さＬ１よりも短い。また、第２取付部４２の長さＬ４は、挿通孔６５の長さＬ１よりも長い。ただし、第２取付部４２の長さＬ４と挿通孔６５の長さＬ１との差（Ｌ４−Ｌ１）は、主部４２２の後端から引掛片４２０の後端までの長さＬ５よりも短い（Ｌ４−Ｌ１＜Ｌ５）。 Here, the relationship between the length dimension of the second mounting portion 42 and the length dimension of the insertion hole 65 of the mounting plate 6 will be described with reference to FIGS. 9A and 9B. Let L1 be the length of the insertion hole 65 in the longitudinal direction (front-back direction). The length from the rear end of the main portion 422 (the left end in FIGS. 9A and 9B) to the front end of the regulation piece 421 (the right end in FIGS. 9A and 9B) in the longitudinal direction of the second mounting portion 42 is defined as L2. The length from the front end of the main portion 422 (the right end in FIGS. 9A and 9B) to the rear end of the hook piece 420 (the left end in FIGS. 9A and 9B) in the longitudinal direction of the second mounting portion 42 is L3. Let L4 be the length from the front end of the restricting piece 421 to the rear end of the hooking piece 420 in the longitudinal direction of the second mounting portion 42. The two lengths L2 and L3 of the second mounting portion 42 are equal, and these lengths L2 and L3 are shorter than the length L1 of the insertion hole 65. Further, the length L4 of the second mounting portion 42 is longer than the length L1 of the insertion hole 65. However, the difference (L4-L1) between the length L4 of the second mounting portion 42 and the length L1 of the insertion hole 65 is shorter than the length L5 from the rear end of the main portion 422 to the rear end of the hook piece 420. (L4-L1 <L5).

したがって、カバー部材４は、２つの第２取付部４２の各々の引掛片４２０を第２の被取付部（取付板６における挿通孔６５の縁及び挿通孔６５の周縁部分）に引っ掛けるようにして取付板６に取り付けられる（図７及び図８参照）。ここで、２つの第２取付部４２のうちで後方に位置する第２取付部４２の規制片４２１は、挿通孔６５を通して取付板６の上面よりも上に突出している（図９Ａ参照）。そのため、カバー部材４の前後方向の移動は、規制片４２１が挿通孔６５の内周面に当たることによって規制されている。その結果、第２取付部４２が取付板６から外れることが抑制されている。 Therefore, the cover member 4 hooks the hook pieces 420 of each of the two second mounting portions 42 on the second mounted portion (the edge of the insertion hole 65 in the mounting plate 6 and the peripheral portion of the insertion hole 65). It is mounted on the mounting plate 6 (see FIGS. 7 and 8). Here, the regulation piece 421 of the second mounting portion 42 located at the rear of the two second mounting portions 42 projects above the upper surface of the mounting plate 6 through the insertion hole 65 (see FIG. 9A). Therefore, the movement of the cover member 4 in the front-rear direction is restricted by the regulation piece 421 hitting the inner peripheral surface of the insertion hole 65. As a result, it is suppressed that the second mounting portion 42 comes off from the mounting plate 6.

次に、本実施形態の照明装置１の施工手順を説明する。まず、施工作業を行う作業者は、天井に本体１０を設置する。すなわち、作業者は、ベース板１２の挿通孔１２０から電源線を引き込んだ後、天井に設けられている埋込孔に本体１０を挿入し、ベース板１２のボルト挿通孔１２１に挿通した吊りボルトにナットを締め付けて本体１０を吊りボルトに取り付ける。さらに、作業者は、挿通孔１２０から引き込んだ電源線を端子台１３に電気的に接続する。 Next, the construction procedure of the lighting device 1 of the present embodiment will be described. First, the worker who performs the construction work installs the main body 10 on the ceiling. That is, the operator draws the power supply line from the insertion hole 120 of the base plate 12, inserts the main body 10 into the embedding hole provided in the ceiling, and inserts the suspension bolt into the bolt insertion hole 121 of the base plate 12. Tighten the nut to attach the main body 10 to the hanging bolt. Further, the operator electrically connects the power supply line drawn from the insertion hole 120 to the terminal block 13.

続いて、作業者は、天井に設置した本体１０に光源ユニット２を取り付ける。まず、作業者は、カバー板４０を左右方向に押して撓ませることにより、４つの第１取付部４１の各々の第１引掛孔４１０及び第２引掛孔４１１から４つの固定部６６の各々の第１固定爪６６０及び第２固定爪６６１を引き抜く。それから、作業者は、カバー部材４を下に引きながら４つの第１取付部４１を取付板６の各挿通孔６５から引き抜く。そして、作業者が取付板６から手を離せば、２つの第２取付部４２が各第２の被取付部に取り付けられることによって、カバー部材４が取付板６から吊り下げられる（図６及び図７参照）。 Subsequently, the operator attaches the light source unit 2 to the main body 10 installed on the ceiling. First, the operator pushes the cover plate 40 in the left-right direction to bend it, so that the first hook hole 410 of each of the four first mounting portions 41 and the second hook hole 411 to the four fixing portions 66 of each of the four fixing portions 66 1 Pull out the fixed claw 660 and the second fixed claw 661. Then, the operator pulls out the four first mounting portions 41 from the insertion holes 65 of the mounting plate 6 while pulling the cover member 4 downward. Then, when the operator releases the attachment plate 6, the cover member 4 is suspended from the attachment plate 6 by attaching the two second attachment portions 42 to the second attachment portions (FIGS. 6 and 6). (See FIG. 7).

作業者は、２つのカバー部材４を取付板６から吊り下げた状態にした後、引掛金具８を枠体１１の引掛孔１１０に挿通し、引掛孔１１０の縁に引掛金具８を引っ掛けることにより、光源ユニット２を本体１０に吊り下げる。この状態で、作業者は、端子台１３から引き出されている電線を電源装置７に電気的に接続する。その後、作業者は、光源ユニット２を持ち上げて本体１０内に収容する。このとき、作業者は、取付板６の４つの支持部６２のそれぞれの固定孔６２３にラッチ１４のつまみを挿通する。それから、作業者は、取付板６の操作孔６３に手を入れて４つのラッチ１４のそれぞれのつまみを９０度回転させる。その結果、光源ユニット２（の取付板６）が、４つのラッチ１４によって本体１０に支持される。ここで、カバー部材４が取付板６に吊り下げられた状態において、カバー部材４の長手方向（前後方向）に沿った枠体１１とカバー部材４との距離（隙間）Ｄ１は、カバー部材４の長手方向に沿った引掛片４２０の長さよりも短い（図１０参照）。そのため、取付板６に吊り下げられたカバー部材４が長手方向に沿って移動した場合、カバー部材４が枠体１１に当たることでカバー部材４の移動が枠体１１によって規制され、引掛片４２０が取付板６における挿通孔６５の縁から外れることがない。 After the two cover members 4 are suspended from the mounting plate 6, the operator inserts the hook metal fitting 8 into the hook hole 110 of the frame body 11 and hooks the hook metal fitting 8 on the edge of the hook hole 110. , The light source unit 2 is suspended from the main body 10. In this state, the operator electrically connects the electric wire drawn from the terminal block 13 to the power supply device 7. After that, the operator lifts the light source unit 2 and accommodates it in the main body 10. At this time, the operator inserts the knob of the latch 14 into each of the fixing holes 623 of the four support portions 62 of the mounting plate 6. Then, the operator puts his / her hand in the operation hole 63 of the mounting plate 6 and rotates each knob of the four latches 14 by 90 degrees. As a result, the light source unit 2 (mounting plate 6) is supported by the main body 10 by the four latches 14. Here, in a state where the cover member 4 is suspended from the mounting plate 6, the distance (gap) D1 between the frame body 11 and the cover member 4 along the longitudinal direction (front-back direction) of the cover member 4 is the cover member 4. It is shorter than the length of the hook piece 420 along the longitudinal direction of the (see FIG. 10). Therefore, when the cover member 4 suspended from the mounting plate 6 moves along the longitudinal direction, the movement of the cover member 4 is restricted by the frame body 11 when the cover member 4 hits the frame body 11, and the hook piece 420 It does not come off from the edge of the insertion hole 65 in the mounting plate 6.

最後に、作業者は、取付板６に２つのカバー部材４をそれぞれ取り付ける。まず、作業者は、カバー部材４の４つの第１取付部４１のそれぞれを対応する挿通孔６５に挿通する。作業者が第１取付部４１を取付板６の下面側から挿通孔６５に挿通すると、固定部６６が第１取付部４１に押されて撓んだ後、第１固定爪６６０が第１取付部４１の第１引掛孔４１０に挿通され、第２固定爪６６１が第１取付部４１の第２引掛孔４１１に挿通される。そして、第１固定爪６６０が第１引掛孔４１０の縁に引っ掛かり、第２固定爪６６１が第２引掛孔４１１の縁に引っ掛かることによって、第１取付部４１が固定部６６に固定される（図４及び図５参照）。そして、取付板６に設けられている操作孔６３や挿通孔６５などは、取付板６に取り付けられるカバー部材４によって覆い隠される（図１参照）。以上のようにして、本実施形態の照明装置１の施工作業が完了する。 Finally, the operator attaches the two cover members 4 to the attachment plate 6, respectively. First, the operator inserts each of the four first mounting portions 41 of the cover member 4 into the corresponding insertion holes 65. When the operator inserts the first mounting portion 41 into the insertion hole 65 from the lower surface side of the mounting plate 6, the fixing portion 66 is pushed by the first mounting portion 41 and bends, and then the first fixing claw 660 is first mounted. It is inserted into the first hook hole 410 of the portion 41, and the second fixing claw 661 is inserted into the second hook hole 411 of the first mounting portion 41. Then, the first fixing claw 660 is hooked on the edge of the first hook hole 410, and the second fixing claw 661 is hooked on the edge of the second hook hole 411, whereby the first mounting portion 41 is fixed to the fixing portion 66 ( (See FIGS. 4 and 5). The operation hole 63, the insertion hole 65, and the like provided in the mounting plate 6 are covered by the cover member 4 attached to the mounting plate 6 (see FIG. 1). As described above, the construction work of the lighting device 1 of the present embodiment is completed.

天井に取り付けられた照明装置１は、外部電源から端子台１３を介して電源装置７に交流電力が供給されたときに電源装置７から各光源モジュール３に直流電力を給電することで各光源モジュール３を点灯させる。各光源モジュール３が点灯すると、光源モジュールから放射される光の一部がカバー部材４のカバー板４０の表面（下面）で反射して下方に照射される。つまり、カバー部材４は、取付板６の操作孔６３などを覆い隠すだけでなく、光源モジュール３から放射される光の一部を反射することで照明装置１の配光特性を調節することができる。 The lighting device 1 mounted on the ceiling is such that each light source module is supplied with DC power from the power supply device 7 to each light source module 3 when AC power is supplied from the external power source to the power supply device 7 via the terminal block 13. Turn on 3. When each light source module 3 is turned on, a part of the light emitted from the light source module is reflected by the surface (lower surface) of the cover plate 40 of the cover member 4 and is irradiated downward. That is, the cover member 4 not only covers the operation hole 63 of the mounting plate 6, but also reflects a part of the light radiated from the light source module 3 to adjust the light distribution characteristic of the lighting device 1. can.

ここで、特許文献１記載の従来例では、照明器具の施工時に器具本体から取り外した反射板の扱いに手間がかかっていた。一方、本実施形態の照明装置１では、上述のようにカバー部材４を取付板６に対して吊り下げるように取り付けることができる。そのため、取付板６を取付板６から取り外さずに光源ユニット２を本体１０に取り付けることができる。その結果、本実施形態の照明装置１は、従来例と比較して、施工作業の作業性の向上を図ることができる。なお、照明装置は、必ずしも本体１０と光源ユニット２を備えている必要はない。例えば、照明装置は、光源（光源モジュール３と透光カバー５）及びカバー部材４が取り付けられた取付板６を造営材（天井又は壁）に直接取り付けるように構成されてもよい。また、照明装置１において、取付板６の下面における第２領域に操作孔６３以外の部材、例えば、端子台１３や電源装置７が配置されても構わない。取付板６の下面における第２領域に端子台１３や電源装置７が配置される場合においても、照明装置１の施工時やメンテナンス時にカバー部材４を取付板６から取り外さずに端子台１３や電源装置７に対する施工作業及びメンテナンス作業を行うことができる。 Here, in the conventional example described in Patent Document 1, it takes time and effort to handle the reflector removed from the main body of the lighting fixture at the time of construction of the lighting fixture. On the other hand, in the lighting device 1 of the present embodiment, the cover member 4 can be attached so as to be suspended from the attachment plate 6 as described above. Therefore, the light source unit 2 can be attached to the main body 10 without removing the attachment plate 6 from the attachment plate 6. As a result, the lighting device 1 of the present embodiment can improve the workability of the construction work as compared with the conventional example. The lighting device does not necessarily have to include the main body 10 and the light source unit 2. For example, the lighting device may be configured to directly attach the mounting plate 6 to which the light source (light source module 3 and the translucent cover 5) and the cover member 4 are attached to the construction material (ceiling or wall). Further, in the lighting device 1, a member other than the operation hole 63, for example, a terminal block 13 or a power supply device 7 may be arranged in a second region on the lower surface of the mounting plate 6.
