(C) shows a state in which the spring portion 230 slides with respect to the connection opening 153 of the connector 150.
(D) shows the state where the light source unit 100 is attached to the instrument body 200.

（１）図１５（ａ）では、器具本体２００にバネ部２３０が取り付けられており、光源ユニット１００は器具本体２００に取り付けられていない状態である。
（２）図１５（ｂ）では、作業者が、バネ部２３０の先端部Ｋを、連結具１５０の連結開口部１５３の開口の縁部に引っ掛けて、光源ユニット１００を器具本体２００に吊り下げた状態を示す。バネ部２３０は図１２のように、２個のバネ部２３０が、器具本体２００の両端に配置されており、反対側のもう一つのバネ部２３０も同様に操作し、光源ユニット１００を器具本体２００に装着できる。
（３）図１５（ｃ）では、作業者が光源ユニット１００を上方（被取付部５００の方向）に持ち上げると、バネ部２３０の円弧形状部２３１の裏面が、連結開口部１５３の開口の縁に対して、バネの復元力（弾性力）により摺動する。
（４）図１５（ｄ）では、作業者が、器具本体２００に光源ユニット１００を差し込むことで、光源ユニット１００の器具本体２００への装着が完了する。 (1) In FIG. 15A, the spring portion 230 is attached to the instrument main body 200, and the light source unit 100 is not attached to the instrument main body 200.
(2) In FIG. 15 (b), the operator hangs the light source unit 100 on the instrument body 200 by hooking the tip K of the spring portion 230 to the edge of the opening of the connection opening 153 of the connector 150. Indicates the state. As shown in FIG. 12, the spring portion 230 has two spring portions 230 disposed at both ends of the instrument main body 200. The other spring portion 230 on the opposite side is operated in the same manner, and the light source unit 100 is moved to the instrument main body. Can be attached to 200.
(3) In FIG. 15C, when the operator lifts the light source unit 100 upward (in the direction of the attached portion 500), the back surface of the arc-shaped portion 231 of the spring portion 230 is the edge of the opening of the connection opening 153. On the other hand, it slides by the restoring force (elastic force) of the spring.
(4) In FIG. 15D, the operator inserts the light source unit 100 into the instrument main body 200, whereby the mounting of the light source unit 100 on the instrument main body 200 is completed.

図１５（ｄ）の状態では、光源ユニット１００の連結具１５０は、器具本体２００のバネ部２３０の弾性力によって引っ張られる。光源ユニット１００は、連結具１５０がバネ部２３０に引っ張られる場合に、一方の縁部２１１−１及び他方の縁部２１５−１（図１２）とは異なる器具本体２００の箇所に当接して、バネ部２３０の弾性力に対抗する光源側当接部１７０を有するが、この実施の形態では、光源側当接部１７０は、第一の光源蓋部１４０−１である。第一の光源蓋部１４０−１が当接する器具本体２００の箇所は、第一の器具蓋部２２０−１である。また光源側当接部１７０は、第二の光源蓋部１４０−２でもある。第二の光源蓋部１４０−２が当接する器具本体２００の箇所は、第二の器具蓋部２２０−２である。図５に示すように、第二の光源蓋部１４０−２が第二の器具蓋部２２０−２に当接してバネ部２３０の弾性力に対抗する場合は、第二の光源蓋部１４０−２の上面側の光源蓋上面部１４０−２ａが第二の器具蓋部２２０−２の光源受部２２３に当接する。同様に、第一の光源蓋部１４０−１が第一の器具蓋部２２０−１に当接してバネ部２３０の弾性力に対抗する場合は、第一の光源蓋部１４０−１の上面側の光源蓋上面部１４０−１ａ（図示していない）が第一の器具蓋部２２０−１の光源受部２２３に当接する。 In the state of FIG. 15D, the connector 150 of the light source unit 100 is pulled by the elastic force of the spring portion 230 of the instrument body 200. When the connector 150 is pulled by the spring portion 230, the light source unit 100 abuts on a place of the instrument body 200 different from the one edge portion 211-1 and the other edge portion 215-1 (FIG. 12), Although it has the light source side contact part 170 which opposes the elastic force of the spring part 230, in this embodiment, the light source side contact part 170 is the 1st light source cover part 140-1. The place of the instrument main body 200 with which the first light source lid part 140-1 abuts is the first instrument lid part 220-1. The light source side contact portion 170 is also a second light source lid portion 140-2. The place of the instrument main body 200 with which the second light source lid part 140-2 abuts is the second instrument lid part 220-2. As shown in FIG. 5, when the second light source lid part 140-2 abuts against the second instrument lid part 220-2 and counters the elastic force of the spring part 230, the second light source lid part 140- 2 on the upper surface side of the light source lid 140-2a comes into contact with the light source receiving portion 223 of the second instrument lid portion 220-2. Similarly, when the first light source lid part 140-1 contacts the first instrument lid part 220-1 and counters the elastic force of the spring part 230, the upper surface side of the first light source lid part 140-1 The light source lid upper surface portion 140-1a (not shown) contacts the light source receiving portion 223 of the first instrument lid portion 220-1.

また、図１５（ｄ）の状態において、光源側当接部１７０は連結具１５０であり、連結具１５０が当接する器具本体２００の箇所は、バネ台座２４０であってもよい。この場合、連結具１５０における連結部１５２の先端１５２ａ（図７）が、バネ台座２４０におけるバネ受部２４２の当接領域２４２ａ（図１３）に当接する。 Further, in the state of FIG. 15D, the light source side contact portion 170 may be the connecting tool 150, and the place of the instrument main body 200 with which the connecting tool 150 contacts may be the spring base 240. In this case, the tip 152a (FIG. 7) of the connecting portion 152 in the connecting tool 150 contacts the contact region 242a (FIG. 13) of the spring receiving portion 242 in the spring base 240.

図１５（ｄ）は光源ユニット１００の器具本体２００への装着が完了した状態である。この完了状態では、図１２及び図４からわかるように、発光素子基板１１０は、実装面１１０ａの反対側の面となる基板裏面１１０ｂが器具本体対向部２１３−１（第三の板形状部２１３）に向くと共に、基板長手方向１１０ｃに沿う一方の長辺１１０−１（図４）が基板長手方向１１０ｃに沿う他方の長辺１１０−２（図４）よりも器具本体対向部２１３−１の近くに配置される。このように配置されることより基板裏面１１０ｂが器具本体対向部２１３−１に対し基板長手方向１１０ｃにわたって斜めになるように配置される。バネ部２３０は、連結具１５０の連結開口部１５３と当接状態にある付近円弧形状部２３１Ａの基板長手方向１１０ｃを法線とする断面が、発光素子基板１１０の基板短手方向１１０ｄを横方向とする横長の矩形をなす。つまり、図１２ではバネ部２３０は省略しているが、図１２における付近円弧形状部２３１Ａの断面は、連結開口部１５３と同様の傾きを持ち、Ｚ方向に横長となる矩形である。 FIG. 15D shows a state where the mounting of the light source unit 100 to the instrument body 200 is completed. In this completed state, as can be seen from FIG. 12 and FIG. 4, the light emitting element substrate 110 has the substrate back surface 110 b which is the surface opposite to the mounting surface 110 a with the instrument body facing portion 213-1 (third plate shape portion 213). ) And one long side 110-1 (FIG. 4) along the substrate longitudinal direction 110c is closer to the instrument body facing portion 213-1 than the other long side 110-2 (FIG. 4) along the substrate longitudinal direction 110c. Located nearby. By being arranged in this way, the substrate back surface 110b is arranged so as to be inclined over the substrate longitudinal direction 110c with respect to the instrument main body facing portion 213-1. The spring portion 230 has a cross section in which the substrate longitudinal direction 110c of the vicinity arc-shaped portion 231A in contact with the connection opening 153 of the connector 150 is normal, and the substrate short direction 110d of the light emitting element substrate 110 is horizontal. It forms a horizontally long rectangle. That is, although the spring portion 230 is omitted in FIG. 12, the cross section of the near arc shape portion 231 </ b> A in FIG. 12 is a rectangle that has the same inclination as the connection opening 153 and is horizontally long in the Z direction.

＊＊＊効果の説明＊＊＊
（１）照明器具１０００では、光源ユニット１００は、連結具１５０がバネ部２３０に引っ張られる場合に、一方の縁部２１１−１及び他方の縁部２１５−１とは異なる器具本体２００の箇所に当接して、バネ部２３０の弾性力に対抗する光源側当接部１７０を有す。よって、光源側当接部１７０によってバネ部２３０の弾性力に確実に対向できるので、光源ユニットを安定して斜めに取り付けできる照明器具を提供できる。また、光源側当接部１７０は一方の縁部２１１−１及び他方の縁部２１５−１とは異なる器具本体２００の箇所に当接するので、本体部２１０に光源側当接部１７０と当接する箇所を設ける必要がなくなる。よって、本体部２１０を一枚の板金から少ない工程の曲げ加工で製造できる。
（２）照明器具１０００では、第四の板形状部２１４を折り曲げ線２１４ａで折り曲げて、上側第四の板形状部２１４−１と、下側第四の板形状部２１４−２とに分けているので、第四の板形状部２１４と第五の板形状部２１５との折り曲げ角度φを折り曲げ加工に適した角度にすることができる。
（３）照明器具１０００では、バネ部２３０は、連結具１５０の連結開口部１５３と当接状態にある付近円弧形状部２３１Ａの基板長手方向１１０ｃを法線とする断面が、発光素子基板１１０の基板短手方向１１０ｄを横方向とする横長の矩形をなす。したがって、図１２のように器具本体２００に対して光源ユニット１００を斜めに装着した場合でもバネ部２３０の剛性が維持できるので、確実に光源ユニット１００を器具本体２００に装着で
きる。
（４）照明器具１０００あるいは照明システム１０００Ａではエンド蓋部を用いるので、長手方向における端部の照射光を制御することができる。
（５）照明システム１０００Ａでは器具蓋部２２０を用いて照明器具どうしを連結するので、簡易な構成でしっかりと照明器具どうしを連結できる。
（６）第四の板形状部２１４は、２辺により構成されており、被取付部５００に近い上側第四の板形状部２１４−１と、被取付部５００に遠く、第五の板形状部２１５に隣接する下側第四の板形状部２１４−２とに分かれる。図１２、図１１に示すように、第四の板形状部２１４は、長手方向に沿う折り曲げ線２１４ａで折り曲げられて中空形状の外側に凸となるが、折り曲げられた上側が上側第四の板形状部２１４−１であり下側が下側第四の板形状部２１４−２である。
（イ）遮光角θを確保したいとする。遮光角θとは図１２に示すように、人が照明器具１０００を見上げた際に光源ユニット１００が遮られる角度θである。図１２では直線Ｌ２が水平線を表し、直線Ｌ１が遮光角θを表している。
（ロ）図１２の場合、遮光角θに加え、作業者がカバー部１３０をつかむ際のつかみ易さのため、空間Ｓを設けたい。第五の板形状部２１５の交点Ａは直線Ｌ１上、あるいは直線Ｌ１よりも下側になければ遮光角θを満足できない。
（ハ）また、照明器具１０００のサイズのコンパクト化の要請から、さらに、照明器具の高さＨを要求されているとする。これら遮光角θ、空間Ｓ、高さＨを満たすには、第四の板形状部２１４を、Ｐ点と交点Ａとを結ぶ平坦な形状とすればよい。この形状により、遮光角θを満たし、空間Ｓを確保し、寸法Ｈを満たすことができる。
（二）さらに、第四の板形状部２１４を折り曲げ線２１４ａで折り曲げて上側第四の板形状部２１４−１と下側第四の板形状部２１４−２に分けることで、第五の板形状部２１５と下側第四の板形状部２１４−２との折り曲げの角度φを緩やかにできる。 *** Explanation of effects ***
(1) In the lighting fixture 1000, the light source unit 100 is placed at a location on the fixture body 200 different from the one edge portion 211-1 and the other edge portion 215-1 when the connector 150 is pulled by the spring portion 230. There is a light source side contact portion 170 that contacts and opposes the elastic force of the spring portion 230. Therefore, since the light source side contact portion 170 can reliably face the elastic force of the spring portion 230, it is possible to provide a luminaire that can stably attach the light source unit obliquely. Further, since the light source side contact portion 170 contacts the place of the instrument body 200 different from the one edge portion 211-1 and the other edge portion 215-1, the light source side contact portion 170 contacts the body portion 210. There is no need to provide a place. Therefore, the main body 210 can be manufactured from a single sheet metal with a small number of processes.
(2) In the lighting fixture 1000, the fourth plate-shaped portion 214 is bent along a folding line 214a, and is divided into an upper fourth plate-shaped portion 214-1 and a lower fourth plate-shaped portion 214-2. Therefore, the bending angle φ between the fourth plate-shaped portion 214 and the fifth plate-shaped portion 215 can be set to an angle suitable for bending.
(3) In the lighting apparatus 1000, the spring portion 230 has a cross section whose normal line is the substrate longitudinal direction 110 c of the arc-shaped portion 231 </ b> A in the vicinity of the connection opening 153 of the connection tool 150. It forms a horizontally long rectangle with the substrate short direction 110d as the horizontal direction. Therefore, even when the light source unit 100 is obliquely attached to the instrument main body 200 as shown in FIG. 12, the rigidity of the spring portion 230 can be maintained, so that the light source unit 100 can be reliably attached to the instrument main body 200.
(4) In the lighting fixture 1000 or the lighting system 1000A, since the end lid portion is used, the irradiation light at the end portion in the longitudinal direction can be controlled.
(5) In the lighting system 1000A, since the lighting fixtures 220 are connected to each other, the lighting fixtures can be firmly connected with a simple configuration.
(6) The fourth plate-shaped portion 214 is composed of two sides, the upper fourth plate-shaped portion 214-1 near the mounted portion 500, and the fifth plate shape far from the mounted portion 500. It is divided into a lower fourth plate-shaped part 214-2 adjacent to the part 215. As shown in FIG. 12 and FIG. 11, the fourth plate-shaped portion 214 is bent at a fold line 214a along the longitudinal direction so as to protrude outward from the hollow shape, but the bent upper side is the upper fourth plate. The shape portion 214-1 and the lower side is the lower fourth plate shape portion 214-2.
(A) Suppose that it is desired to secure the light shielding angle θ. The light blocking angle θ is an angle θ at which the light source unit 100 is blocked when a person looks up at the lighting fixture 1000 as shown in FIG. In FIG. 12, the straight line L2 represents a horizontal line, and the straight line L1 represents the light shielding angle θ.
(B) In the case of FIG. 12, in addition to the light blocking angle θ, it is desirable to provide a space S for ease of grasping when the operator grasps the cover portion 130. If the intersection A of the fifth plate-shaped portion 215 is not on the straight line L1 or below the straight line L1, the light shielding angle θ cannot be satisfied.
(C) Further, it is assumed that the height H of the lighting fixture is further requested from the request for downsizing of the lighting fixture 1000. In order to satisfy the light shielding angle θ, the space S, and the height H, the fourth plate-shaped portion 214 may be a flat shape that connects the point P and the intersection point A. With this shape, the light shielding angle θ can be satisfied, the space S can be secured, and the dimension H can be satisfied.
(2) Further, the fourth plate-shaped portion 214 is bent at a fold line 214a to be divided into an upper fourth plate-shaped portion 214-1 and a lower fourth plate-shaped portion 214-2, whereby the fifth plate The bending angle φ between the shape portion 215 and the lower fourth plate shape portion 214-2 can be moderated.

エンド蓋部３００は、金属材料による成形でも良く、樹脂部材のようなものでも良い。また、樹脂材料で形成した際にはエンドグ蓋凸部が貫通孔２２１ａに嵌め込まれるようなものでも良い。 The end lid part 300 may be formed of a metal material or a resin member. Further, when formed of a resin material, the end cover convex portion may be fitted into the through hole 221a.
