カバーエンド33は、合成樹脂製であって、カバー本体32の長手方向の両端の開口を塞ぐように、取付板5に取り付けられている(図2参照)。カバーエンド33は、上端に設けられている一対の爪部330が、取付板5に設けられている一対の孔503に挿入され、かつ、取付板5の上面側における孔503の周囲に引っ掛かることにより、取付板5に取り付けられている(図3参照)。   The cover end 33 is made of synthetic resin, and is attached to the attachment plate 5 so as to close the openings at both ends in the longitudinal direction of the cover body 32 (see FIG. 2). In the cover end 33, a pair of claw portions 330 provided at the upper end are inserted into a pair of holes 503 provided in the mounting plate 5, and are caught around the holes 503 on the upper surface side of the mounting plate 5. Is attached to the attachment plate 5 (see FIG. 3).

カバー本体32は、取付板5に設けられている複数の支持部51に、鍔部322に設けられている複数の差込部324がそれぞれ差し込まれることで取付板5に取り付けられている(図4及び図5参照)。支持部51は、取付板5の下面において、光源モジュール30の前後両側に、光源モジュール30の長手方向に沿って並ぶように2つずつ配置されている。つまり、支持部51は、カバー本体32の一対の鍔部322に2つずつ設けられている差込部324と1対1に対応している。   The cover main body 32 is attached to the attachment plate 5 by inserting a plurality of insertion portions 324 provided in the flange portion 322 into a plurality of support portions 51 provided in the attachment plate 5 (FIG. 4 and FIG. 5). Two support portions 51 are arranged on the lower surface of the mounting plate 5 on both the front and rear sides of the light source module 30 so as to be aligned along the longitudinal direction of the light source module 30. That is, the support portions 51 correspond one-to-one with the insertion portions 324 that are provided in two on the pair of flange portions 322 of the cover main body 32.

支持部51は、図4〜図6に示すように、下から見て袋状、具体的には、1つの側面(差込口510)が開放された角錐台形状に形成されている。なお、支持部51は、例えば、取付板5に直線状の切り込み(ランス)が設けられ、切り込みの片側が下向きにプレスされることで形成されている。つまり、支持部51は、上から見ると、切り込みによって1つの側面が開放された角錐台形状の凹所となっている。   As shown in FIGS. 4 to 6, the support portion 51 is formed into a bag shape when viewed from below, specifically, a truncated pyramid shape with one side surface (insertion opening 510) opened. The support 51 is formed, for example, by providing a straight cut (lance) on the mounting plate 5 and pressing one side of the cut downward. That is, when viewed from above, the support portion 51 is a truncated pyramid-shaped recess whose one side surface is opened by cutting.

カバー本体32は、片側の鍔部322の2つの差込部324が差込口510から支持部51に差し込まれた後、主部320が短手方向(前後方向)に撓ませられた状態で、反対側の鍔部322の2つの差込部324が差込口510から支持部51に差し込まれる。そして、カバー本体32は、一対の鍔部322の合計4つの差込部324が、それぞれ対応する4つの支持部51に支持されることで取付板5に取り付けられている(図4〜図6参照)。つまり、カバー本体32は、ドライバなどの工具を使わずに取付板5に取りつられる。そのため、例えば、カバー本体32がねじ止めされる場合と比較して、組立の作業性の向上を図ることができる。しかも、支持部51は、カバー本体32の短手方向に沿って差込部324が差し込まれる向き(前後方向)に差込口510が開いている。ゆえに、カバー本体32は、取付板5の下面の法線方向から取付可能である。そのため、図2に示すように、強度向上のために取付板5の周縁部分が全周に渡って下向きに曲げ起こされていても、これらの曲げ起こされた部分が、取付板5へのカバー本体32の取付作業の邪魔になることがない。その結果、取付板5の大きさや形状などが、取付板5へのカバー本体32の取付作業に必要なスペースに制約され難い。一方、特許文献1記載の従来例のように、取付板の下面と平行な方向からカバー本体がスライドされて取り付けられる場合、取付板の周縁の曲げ起こされた部分が、取付板へのカバー本体の取付作業の邪魔になる可能性が高い。   The cover body 32 is in a state where the main portion 320 is bent in the short direction (front-rear direction) after the two insertion portions 324 of the flange portion 322 on one side are inserted into the support portion 51 from the insertion port 510. The two insertion portions 324 of the opposite flange portion 322 are inserted into the support portion 51 from the insertion port 510. And the cover main body 32 is attached to the attachment board 5 by the total four insertion parts 324 of a pair of collar parts 322 being each supported by the corresponding four support parts 51 (FIGS. 4-6). reference). That is, the cover main body 32 is attached to the mounting plate 5 without using a tool such as a screwdriver. Therefore, for example, the assembly workability can be improved as compared with the case where the cover main body 32 is screwed. In addition, the support portion 51 has the insertion port 510 opened in the direction (front-rear direction) in which the insertion portion 324 is inserted along the short direction of the cover main body 32. Therefore, the cover main body 32 can be attached from the normal direction of the lower surface of the attachment plate 5. Therefore, as shown in FIG. 2, even if the peripheral portion of the mounting plate 5 is bent downward over the entire circumference to improve the strength, these bent portions are covered by the cover to the mounting plate 5. There is no hindrance to the attachment work of the main body 32. As a result, the size, shape, and the like of the mounting plate 5 are not easily restricted by the space required for the operation of mounting the cover main body 32 on the mounting plate 5. On the other hand, when the cover body is slid and mounted from the direction parallel to the lower surface of the mounting plate as in the conventional example described in Patent Document 1, the bent portion of the peripheral edge of the mounting plate is the cover body to the mounting plate. There is a high possibility that it will interfere with the installation work.

ここで、鍔部322は、カバー本体32の短手方向に沿った幅W1が、カバー本体32の短手方向に沿った支持部51の長さL1よりも大きくなる(L1<W1)ように形成されている(図6参照)。ゆえに、差込口510から支持部51内に挿入される差込部324の量(カバー本体32の短手方向の長さ)が増えることにより、支持部51の支持強度の向上が図られる。   Here, the flange portion 322 has a width W1 along the short direction of the cover main body 32 larger than the length L1 of the support portion 51 along the short direction of the cover main body 32 (L1 <W1). It is formed (see FIG. 6). Therefore, the support strength of the support part 51 can be improved by increasing the amount of the insertion part 324 inserted into the support part 51 from the insertion opening 510 (the length of the cover body 32 in the short direction).

上述のように本実施形態に係る照明器具Xは、1つ又は複数の光源モジュール30と、前面(下面)に光源モジュール30が取り付けられる取付板5とを有している。また、本実施形態に係る照明器具Xは、透光性を有する材料で形成され、光源モジュール30を前方(下方)から覆うように取付板5の前面に取り付けられるカバー31とを有している。光源モジュール30は、長尺の基板301と、基板301の前面に実装されている複数の固体発光素子(LED300)とを備えている。カバー31は、一面が開放された長尺の箱状に形成されているカバー本体32を有している。さらに、カバー31は、カバー本体32の開放されている側の縁において長手方向に沿ってカバー本体32から離れる向きに突出する鍔部322と、鍔部322に設けられている1つ又は複数の差込部324とを有している。取付板5は、口の開いた袋状であって、口(差込口510)から差込部324が差し込まれ、かつ、差し込まれた差込部324を支持する1つ又は複数の支持部51が設けられている。支持部51は、カバー本体32の短手方向に沿って差込部324が差し込まれる向きに差込口510が開いている。   As described above, the lighting fixture X according to the present embodiment includes one or a plurality of light source modules 30 and the mounting plate 5 to which the light source modules 30 are attached on the front surface (lower surface). Moreover, the lighting fixture X which concerns on this embodiment is formed with the material which has translucency, and has the cover 31 attached to the front surface of the attachment board 5 so that the light source module 30 may be covered from the front (downward). . The light source module 30 includes a long substrate 301 and a plurality of solid state light emitting elements (LEDs 300) mounted on the front surface of the substrate 301. The cover 31 has a cover body 32 formed in a long box shape with one surface open. Further, the cover 31 has a flange 322 that protrudes in the direction away from the cover body 32 along the longitudinal direction at the edge of the cover body 32 that is open, and one or more of the cover 31 provided on the flange 322. And an insertion portion 324. The mounting plate 5 is in a bag shape with an open mouth, and the insertion portion 324 is inserted from the mouth (insertion port 510), and one or a plurality of support portions that support the inserted insertion portion 324 51 is provided. In the support portion 51, the insertion port 510 is open in the direction in which the insertion portion 324 is inserted along the short direction of the cover body 32.

本実施形態に係る照明器具Xが上述のように構成されれば、鍔部322の差込部324が差込口510から差し込まれて支持部51に支持されるから、ねじ止めと比較して、取付板5へのカバー本体32の取付(組立)の作業性の向上を図ることができる。しかも、本実施形態に係る照明器具Xは、カバー本体32の短手方向から、差込部324が差込口510に差し込まれるので、取付板5の前面(下面)と平行にカバー本体がスライドされて取り付けられる場合に比べ、取付板5の大きさや形状などが制約され難い。その結果、本実施形態に係る照明器具Xは、組立の作業性の向上を図りつつカバー以外の部材の大きさや形状などの制約を受け難くすることができる。   If the lighting fixture X which concerns on this embodiment is comprised as mentioned above, since the insertion part 324 of the collar part 322 is inserted from the insertion port 510 and supported by the support part 51, compared with screwing. The workability of attaching (assembling) the cover main body 32 to the attachment plate 5 can be improved. Moreover, in the lighting fixture X according to this embodiment, since the insertion portion 324 is inserted into the insertion port 510 from the short side direction of the cover body 32, the cover body slides in parallel with the front surface (lower surface) of the mounting plate 5. The size and shape of the mounting plate 5 are less likely to be constrained than when the mounting plate 5 is mounted. As a result, the lighting fixture X according to the present embodiment can be made less susceptible to restrictions such as the size and shape of members other than the cover while improving the assembly workability.

また、本実施形態に係る照明器具Xにおいて、鍔部322は、カバー本体32の短手方向に沿った幅W1が、カバー本体32の短手方向に沿った支持部51の長さL1よりも大きくなる(L1<W1)ように形成されていることが好ましい。   Further, in the lighting fixture X according to the present embodiment, the collar portion 322 has a width W1 along the short direction of the cover body 32 that is longer than the length L1 of the support portion 51 along the short direction of the cover body 32. It is preferably formed so as to be large (L1 <W1).

本実施形態に係る照明器具Xが上述のように構成されれば、差込口510から支持部51内に挿入される差込部324の量(カバー本体32の短手方向の長さ)が増えることにより、支持部51の支持強度の向上を図ることができる。   If the lighting fixture X which concerns on this embodiment is comprised as mentioned above, the quantity (length of the transversal direction of the cover main body 32) of the insertion part 324 inserted in the support part 51 from the insertion port 510 will be sufficient. By increasing, the support strength of the support part 51 can be improved.

ところで、反射部材7は、一対の固定片72がカバー本体32の鍔部322に重ねられ、取付板5に設けられているねじ挿通孔に上から挿通されるねじ501がねじ孔720にねじ込まれることにより、取付板5に取り付けられている(図6参照)。つまり、反射部材7の固定片72と取付板5(の下面)との間で、カバー本体32の鍔部322が挟み込まれている。つまり、反射部材7の固定片72と取付板5と間に鍔部322が挟み込まれるので、差込部324が支持部51から抜け難くなり、取付板5に対するカバー本体32の取付強度の向上が図られている。   By the way, in the reflecting member 7, a pair of fixing pieces 72 are overlapped on the flange portion 322 of the cover body 32, and a screw 501 inserted from above into a screw insertion hole provided in the mounting plate 5 is screwed into the screw hole 720. By this, it is attached to the attachment plate 5 (see FIG. 6). That is, the flange 322 of the cover body 32 is sandwiched between the fixed piece 72 of the reflecting member 7 and the attachment plate 5 (the lower surface thereof). That is, since the flange portion 322 is sandwiched between the fixing piece 72 of the reflecting member 7 and the mounting plate 5, the insertion portion 324 is difficult to be removed from the support portion 51, and the mounting strength of the cover body 32 with respect to the mounting plate 5 is improved. It is illustrated.
