Description

本発明は、照明装置に関するものである。特に、灯具におけるカバーの劣化防止に係るものである。 The present invention relates to a lighting device. In particular, it relates to the prevention of deterioration of the cover in the lamp.

照明装置において、壁等に取り付けるための照明器具と、カバーで覆われた光源を有し、照明器具に取り付けられる灯具とを備えるものがある。このような照明装置において、照明器具の側壁下端部に設けられた突片により、灯具と照明器具との間の隙間を少なくし、灯具と照明器具との境界部分における明るさの低下を抑えつつ、照明器具の小型化をはかるものがある。 Some luminaires include a luminaire for mounting on a wall or the like, and a luminaire having a light source covered with a cover and being attached to the luminaire. In such a luminaire, the protrusions provided at the lower end of the side wall of the luminaire reduce the gap between the luminaire and the luminaire, and suppress the decrease in brightness at the boundary between the luminaire and the luminaire. , There are things to reduce the size of lighting equipment.

特許第６４８１９４１号公報Japanese Patent No. 6481941

しかしながら、上述した照明装置は、照明器具本体において側壁に設けられた突片が、灯具におけるカバーの側壁と鉛直方向において、重なった構成になっている。このため、照明器具本体の側壁に流体が付着すると、流れ落ちた流体が、カバーの側壁等に滴下する。 However, the above-mentioned lighting device has a configuration in which protrusions provided on the side wall of the main body of the lighting fixture overlap with the side wall of the cover of the lamp in the vertical direction. Therefore, when the fluid adheres to the side wall of the main body of the luminaire, the fluid that has flowed down drops on the side wall of the cover or the like.

灯具が有するカバー等は、樹脂材料により形成される樹脂成型部品である。このため、照明装置が、油脂等を取り扱う環境に設置される場合では、カバー等に特殊な薬剤、油脂等が付着する可能性がある。そして、付着する薬剤等の種類（組成）によっては、カバー等に、クレージング等のダメージを与えてしまうおそれがある。 The cover or the like of the lamp is a resin molded part formed of a resin material. Therefore, when the lighting device is installed in an environment where oils and fats are handled, special chemicals, oils and fats and the like may adhere to the cover and the like. Then, depending on the type (composition) of the attached chemicals or the like, there is a risk of causing damage such as crazing to the cover or the like.

また、上述した照明装置では、突片の近くに位置するカバーの側壁は、下に向かって互いに離れるように外側に湾曲する形状である。したがって、ケースの外表面は、照明器具本体側に向く成分を有する傾斜面となっている。このため、突片から滴下する流体は、流下を妨げられる。このとき、滞留した異物等によって、灯具においては、側方への光の照射の妨げとなるおそれがある。また、流体内の薬剤等の濃度が高くなることによって、カバーへのクレージング等のダメージの進行を加速させるおそれがある。 Further, in the above-mentioned lighting device, the side walls of the cover located near the projecting pieces are curved outward so as to be separated from each other downward. Therefore, the outer surface of the case is an inclined surface having a component facing the main body of the luminaire. Therefore, the fluid dripping from the projecting piece is prevented from flowing down. At this time, the accumulated foreign matter or the like may hinder the irradiation of light to the side of the lamp. In addition, an increase in the concentration of the chemical or the like in the fluid may accelerate the progress of damage such as crazing on the cover.

本発明は、上記の課題に鑑み、灯具が有するカバーの劣化を防止することができる照明装置を提供することを目的とする。 In view of the above problems, an object of the present invention is to provide a lighting device capable of preventing deterioration of a cover of a lamp.

本発明に係る照明装置は、光源となる発光素子を収容するカバーを有する灯具と、灯具が装着される照明器具とを備える照明装置であって、照明器具は、灯具が装着される開口面と対向する器具底面部と、第１方向に沿って、器具底面部から立ち上がって設けられる壁となり、第１方向と交わる第２方向で互いに対向する対となる一組の器具側面部とを有し、鉛直方向に沿って灯具が装着された照明器具を見たときに、器具側面部の開口面側の端部の最端部分が、外部に露出するカバーの外周部との間に隙間を有して配置されるものである。 The luminaire according to the present invention is a luminaire including a lamp having a cover for accommodating a light emitting element serving as a light source and a luminaire on which the luminaire is mounted. The luminaire has an opening surface on which the luminaire is mounted. It has an opposing bottom surface of the fixture and a pair of side surfaces of the fixture that stand up from the bottom of the fixture along the first direction and are opposed to each other in the second direction intersecting the first direction. When looking at a luminaire with a lamp mounted along the vertical direction, the end of the side surface of the luminaire on the opening surface side has a gap between it and the outer periphery of the cover exposed to the outside. It is arranged as follows.

本発明によれば、鉛直方向から見て、照明器具の器具側面部における開口面側の最端部が、灯具のカバーにおける外周部と重ならず、隙間を有して配置される。このため、照明器具から流下した流体がカバーに滴下せず、カバーの劣化を防止することができる。 According to the present invention, when viewed from the vertical direction, the end of the side surface of the luminaire on the opening surface side does not overlap with the outer peripheral portion of the cover of the luminaire, and is arranged with a gap. Therefore, the fluid flowing down from the luminaire does not drip onto the cover, and deterioration of the cover can be prevented.

ここで、以下の説明において、照明装置１の長手側に沿った方向を、第１方向となる長手方向Ｘとする。また、長手方向Ｘに直交し、長手方向Ｘに対する短手側に沿った方向を、第２方向となる短手方向Ｙとする。そして、長手方向Ｘおよび短手方向Ｙのいずれとも直交する方向を、第３方向となる上下方向Ｚとする。ここで、実施の形態１における上下方向Ｚは、鉛直方向であるものとする。また、長手方向Ｘにおいて、長手端部側への向きを、端向きＸ１とする。そして、端向きＸ１と反対側への向きであり、長手中央側への向きを、中向きＸ２とする。さらに、上下方向Ｚにおいて、照明装置１が取り付けられる造営部９の側（すなわち、天井または壁側）への向きを、上向きＺ１とする。そして、上向きＺ１と反対側への向きであり、照明装置１から光が照射される照射空間側への向きを、下向きＺ２とする。ここで、上向きＺ１は、灯具３が照明器具２に取り付けられる向きである。また、下向きＺ２は、灯具３が照明器具２から取り外される向きである。 Here, in the following description, the direction along the longitudinal side of the lighting device 1 is referred to as the longitudinal direction X, which is the first direction. Further, the direction orthogonal to the longitudinal direction X and along the lateral side with respect to the longitudinal direction X is defined as the lateral direction Y which is the second direction. Then, the direction orthogonal to both the longitudinal direction X and the lateral direction Y is defined as the vertical direction Z which is the third direction. Here, it is assumed that the vertical direction Z in the first embodiment is the vertical direction. Further, in the longitudinal direction X, the direction toward the longitudinal end portion is defined as the end direction X1. Then, the direction is opposite to the end direction X1 and the direction toward the longitudinal center side is the middle direction X2. Further, in the vertical direction Z, the direction toward the side (that is, the ceiling or wall side) of the construction unit 9 to which the lighting device 1 is attached is defined as upward Z1. Then, the direction toward the side opposite to the upward Z1 and the direction toward the irradiation space side where the light is irradiated from the lighting device 1 is defined as the downward Z2. Here, the upward Z1 is the direction in which the lamp 3 is attached to the luminaire 2. Further, the downward Z2 is the direction in which the lamp 3 is removed from the luminaire 2.

In the first embodiment, a so-called trough type luminaire 2 is shown as an example.

＜照明器具２＞
照明器具２は、灯具３が取り付けられる器具である。照明器具２は、器具本体２０を有する。器具本体２０は、実施の形態１では、金属製の板材を折り曲げて形成される。器具本体２０は、照明器具２を天井等の造営部９に取り付けるための取付部である器具底面部２１、２つで一組となる器具側面部２２および２つで一組となる器具端部２３を有する。器具底面部２１は、長手方向Ｘに長尺、かつ、後述する開口面に対向して、長手方向Ｘおよび短手方向Ｙに延びる平板状に形成されている。器具底面部２１は、短手方向Ｙにおける側縁部間の距離が最小幅となる。また、対となる２つで一組の器具側面部２２は、器具底面部２１の短手方向Ｙの両端に配置されている。また、２つで一組となる対の器具端部２３は、器具底面部２１の長手方向Ｘの両端に配置されている。また、図１、図２および図５に示すように、器具端部２３には、ノックアウト２４が形成され、後述する配線材８５における電源線８１等の各種電線を挿通する際に取り外される。 <Lighting fixture 2>
The lighting fixture 2 is a fixture to which the lighting fixture 3 is attached. The lighting fixture 2 has a fixture body 20. In the first embodiment, the instrument main body 20 is formed by bending a metal plate material. The fixture body 20 includes a fixture bottom portion 21, which is an attachment portion for attaching the lighting fixture 2 to a construction portion 9 such as a ceiling, a fixture side portion 22 which is a set of two, and a fixture end portion which is a set of two. 23. The instrument bottom surface portion 21 is formed in a flat plate shape that is long in the longitudinal direction X and extends in the longitudinal direction X and the lateral direction Y so as to face the opening surface described later. The minimum width of the instrument bottom surface portion 21 is the distance between the side edge portions in the lateral direction Y. Further, a pair of two pair of instrument side surface portions 22 are arranged at both ends of the instrument bottom surface portion 21 in the lateral direction Y. Further, a pair of instrument end portions 23, which are a set of two, are arranged at both ends of the instrument bottom surface portion 21 in the longitudinal direction X. Further, as shown in FIGS. 1, 2 and 5, a knockout 24 is formed at the end portion 23 of the appliance, and is removed when various electric wires such as a power line 81 in the wiring material 85 described later are inserted.

図２に示す装着部２５は、装着された灯具３の一部を収容する収容部となる。装着部２５は、器具本体２０の器具底面部２１、一組の器具側面部２２および一組の器具端部２３により、一面が開口した開口面を有する凹形状（箱形状）に形成される。このため、装着部２５は、器具本体２０の器具底面部２１、一組の器具側面部２２および一組の器具端部２３で囲まれる空間を形成している。ここで、装着部２５が収容する灯具３の一部は、照射側ではない非照射部となる。また、図６等に示すように、装着部２５の空間のうち、灯具３が収容された状態で、灯具３に占有されていない部分は、後述する配線材８５等が灯具３に接続される際に経由し、配置される配線領域となる。 The mounting portion 25 shown in FIG. 2 serves as a housing portion for accommodating a part of the mounted lamp 3. The mounting portion 25 is formed in a concave shape (box shape) having an opening surface with one open surface by the instrument bottom surface portion 21 of the instrument body 20, the instrument side surface portion 22 and the instrument end portion 23. Therefore, the mounting portion 25 forms a space surrounded by the instrument bottom surface portion 21, the instrument side surface portion 22, and the instrument end portion 23 of the instrument body 20. Here, a part of the lamp 3 accommodated by the mounting portion 25 is a non-irradiating portion that is not on the irradiation side. Further, as shown in FIG. 6 and the like, in the space of the mounting portion 25, in the portion where the lamp 3 is housed and not occupied by the lamp 3, the wiring material 85 or the like described later is connected to the lamp 3. It becomes a wiring area to be arranged via the case.

一組の器具側面部２２は、長手方向Ｘにおける装着部２５の周壁部であり、器具底面部２１の長手方向Ｘに沿って並行するように、器具底面部２１の側縁部を基端部として、対をなして立ち上がる側壁である。器具側面部２２は、器具底面部２１に対して垂直に立ち上がる第１側面部２２０と、第１側面部２２０の下端である屈曲部２２２から、短手方向Ｙにおける内側に向かって傾斜する第２側面部２２１とを有する。ここで、一組の器具側面部２２において、第１側面部２２０間の距離は、短手方向Ｙにおける器具底面部２１の最小幅となる側縁部間の距離と同じである。そして、第２側面部２２１間の距離は、短手方向Ｙにおける器具底面部２１の側縁部間の距離よりも短くなる。このため、器具側面部２２は、器具底面部２１の幅の領域よりも内側に位置する。第２側面部２２１における下端の側は、短手方向Ｙにおける内側に巻かれて、カール状に曲げられたカール部２２３となっている。カール部２２３は、後述するように、一組の器具側面部２２において、短手方向Ｙの間隔が最も狭い部分となる。カール部２２３の下端は、後述する開口端部２６となり、上下方向Ｚにおいて、器具側面部２２で最端となる部分となる。また、後述するようにカール部２２３の内側に巻かれた部分の端部と第２側面部２２１との間は隙間を有する。さらに、後述するように、カール部２２３の内側は、巻かれて形成されることで、捕捉溝２２４となる空間を有する。ここで、第２側面部２２１およびカール部２２３は、後述する灯具３の透光性カバー３０に対向するように、端部カバー４０が配置されない範囲に設けられる。 A set of instrument side surface portions 22 are peripheral wall portions of the mounting portion 25 in the longitudinal direction X, and the side edge portion of the instrument bottom surface portion 21 is a base end portion so as to be parallel to the instrument bottom surface portion 21 along the longitudinal direction X. It is a side wall that stands up in pairs. The instrument side surface portion 22 is a second inclined inward in the lateral direction Y from the first side surface portion 220 that rises perpendicularly to the instrument bottom surface portion 21 and the bent portion 222 that is the lower end of the first side surface portion 220. It has a side surface portion 221 and. Here, in the set of instrument side surface portions 22, the distance between the first side surface portions 220 is the same as the distance between the side edge portions which is the minimum width of the instrument bottom surface portion 21 in the lateral direction Y. Then, the distance between the second side surface portions 221 is shorter than the distance between the side edge portions of the instrument bottom surface portion 21 in the lateral direction Y. Therefore, the instrument side surface portion 22 is located inside the width region of the instrument bottom surface portion 21. The lower end side of the second side surface portion 221 is a curl portion 223 that is wound inward in the lateral direction Y and bent in a curl shape. As will be described later, the curl portion 223 is a portion of a set of instrument side surface portions 22 having the narrowest interval in the lateral direction Y. The lower end of the curl portion 223 becomes the opening end portion 26, which will be described later, and is the endmost portion of the instrument side surface portion 22 in the vertical direction Z. Further, as will be described later, there is a gap between the end portion of the portion wound inside the curl portion 223 and the second side surface portion 221. Further, as will be described later, the inside of the curl portion 223 has a space that becomes a catching groove 224 by being wound and formed. Here, the second side surface portion 221 and the curl portion 223 are provided in a range in which the end cover 40 is not arranged so as to face the translucent cover 30 of the lamp 3 described later.

器具本体２０の下端に位置する開口端部２６は、器具本体２０において開口している部分の端部であり、器具側面部２２の先端部となる。開口端部２６は、照明器具２の装着部２５に対して、灯具３の着脱を行う際の装着口となる。器具本体２０の開口端部２６において、長手方向Ｘの両端部には、連結部２７が形成されている。連結部２７には、灯具３が取り付けられる。灯具３が連結部２７に取り付けられて支えられている。実施の形態１では、連結部２７は、器具端部２３と一体に形成されており、開口端部２６から長手方向Ｘにおける中向きＸ２に向かって、折り曲げて形成されている。連結部２７に形成されたネジ孔２８は、灯具３に取り付けられた、後述する連結ネジ４８がねじ止めされる孔である。灯具３は、連結ネジ４８によって照明器具２にねじ止めされて固定される。 The open end portion 26 located at the lower end of the instrument main body 20 is the end portion of the portion of the instrument main body 20 that is open, and is the tip end portion of the instrument side surface portion 22. The opening end portion 26 serves as a mounting port for attaching / detaching the lamp 3 to / from the mounting portion 25 of the lighting fixture 2. In the open end portion 26 of the instrument main body 20, connecting portions 27 are formed at both ends in the longitudinal direction X. The lamp 3 is attached to the connecting portion 27. The lamp 3 is attached to and supported by the connecting portion 27. In the first embodiment, the connecting portion 27 is integrally formed with the instrument end portion 23, and is formed by bending from the opening end portion 26 toward the inward X2 in the longitudinal direction X. The screw hole 28 formed in the connecting portion 27 is a hole attached to the lamp 3 to which the connecting screw 48 described later is screwed. The lamp 3 is screwed to and fixed to the luminaire 2 by the connecting screw 48.

＜灯具３＞
次に、主として図３および図４を用いて灯具３について説明する。灯具３は、照明器具２に取り付けられることによって照明装置１を構成する。照明具および光源ユニットとなる灯具３は、長尺状に形成されており、照明器具２に装着されて使用される。実施の形態１では、灯具３は、照明器具２の長手方向Ｘにおける両端部において、後述する連結ネジ４８によって照明器具２の連結部２７に取り付けられる。実施の形態１の灯具３は、図２、図３および図６に示すように、主として、透光性カバー３０、端部カバー４０、発光部６０等を有する。 <Lamp 3>
Next, the lamp 3 will be described mainly with reference to FIGS. 3 and 4. The lighting device 3 constitutes the lighting device 1 by being attached to the lighting device 2. The luminaire and the luminaire 3 serving as the light source unit are formed in a long shape and are used by being attached to the luminaire 2. In the first embodiment, the lamp 3 is attached to the connecting portion 27 of the lighting fixture 2 by the connecting screws 48 described later at both ends of the lighting fixture 2 in the longitudinal direction X. As shown in FIGS. 2, 3 and 6, the lamp 3 of the first embodiment mainly has a translucent cover 30, an end cover 40, a light emitting portion 60 and the like.

＜透光性カバー３０＞

Here, with respect to the outer peripheral portion 37 of the portion of the translucent cover 30 exposed to the outside, the direction of the normal line with respect to the outer surface portion is within the range from the direction along the optical axis of the light emitting element 61 to the direction orthogonal to the optical axis. It has become. For example, when the lamp 3 is mounted on the luminaire 2 so that the light is emitted downward from the luminaire 1, the portion exposed to the outside from the mounting portion 25 of the translucent cover 30 is The outer surface faces downward, diagonally downward, or laterally (horizontally outward). That is, the outer surface portion of the portion of the translucent cover 30 exposed to the outside from the mounting portion 25 does not face upward or diagonally upward. Further, the portion of the translucent cover 30 housed in the mounting portion 25 and not exposed to the outside covers the side of the control unit 80 and the pedestal 51 on which the control unit 80 of the mounting surface portion 52 is arranged. The surface of the translucent cover 30 housed in the mounting portion 25 and not exposed to the outside faces the instrument bottom surface 21 of the instrument body 20 and the set of instrument side surfaces 22. Here, the translucent cover 30 may have light diffusivity, wavelength discrimination, and the like, depending on the specifications of the product and the like. Further, the portion of the translucent cover 30 that is not exposed to the outside may be formed by using a material having reflectivity, light shielding property, or the like.

実施の形態１に示す筒形の透光性カバー３０は、図１から図６に示すように、内部に収容される機器を覆い、内部に収容される機器に対する位置によって、一組の並行部３１、第１接続部３２および第２接続部３３に分かれている。一組の並行部３１は、透光性カバー３０において、一組の面が同じ距離で並行する面を形成している。透光性カバー３０は、一組の並行部３１の外側の面部分となる外面部および内側の面部分となる内面部が、それぞれ、ともに平面形状である。一組の外面部および一組の内面部は、透光性カバー３０に収容される発光素子６１の光軸に沿った平面である。実施の形態１では、この平面は、灯具３が照明器具２に装着された状態で、上下方向Ｚに沿っている。さらに、この平面は、一組の外面部および一組の内面部が、灯具３が照明器具２に装着された状態で、それぞれ対向する器具側面部２２に沿った平面でもあり、それぞれ対向するカール部２２３に沿った平面でもある。そして、この平面は、灯具３が照明器具２に取り付けられる向きまたは照明器具２から取り外される向きに沿った平面にもなる。このため、透光性カバー３０の並行部３１は、短手方向Ｙにおいて、器具側面部２２より外側にはならず、器具側面部２２の内側に位置し、カール部２２３と対向する。並行部３１のうち、灯具３が照明器具２に装着されたときに露出している部分は、灯具３の側方における照射部となる。また、実施の形態１の照明装置１において、一組の並行部３１間の距離は、灯具における最も広い部分となる。 As shown in FIGS. 1 to 6, the tubular translucent cover 30 shown in the first embodiment covers a device housed inside, and a set of parallel portions depending on the position with respect to the device housed inside.

It is also a plane along the portion 223. Then, this plane also becomes a plane along the direction in which the lamp 3 is attached to the luminaire 2 or the direction in which the lamp 3 is removed from the luminaire 2. Therefore, the parallel portion 31 of the translucent cover 30 is located inside the instrument side surface portion 22 and faces the curl portion 223, not outside the instrument side surface portion 22 in the lateral direction Y. The portion of the parallel portion 31 that is exposed when the lamp 3 is attached to the luminaire 2 becomes an irradiation portion on the side of the lamp 3. Further, in the lighting device 1 of the first embodiment, the distance between a set of parallel portions 31 is the widest portion in the lamp.

配線材８５は、外部から灯具３に接続される、電源線８１、接地線８２および制御線８３等の各種配線を有する。また、これらの配線を接続する端子、配線保持具およびソケット等も配線材８５とする。図６では、灯具３と接続される電源線８１、接地線８２および制御線８３を、配線材８５として示している。配線材８５は、それぞれ絶縁材料で被包された各配線を被覆で一纏めにしたり、結束バンドで束ねたりした状態で、装着部２５内の配線領域に配置されるようにしてもよい。また、各配線をバラバラに分離した状態で、装着部２５内の配線領域に配置されるようにしてもよい。 The wiring material 85 has various wirings such as a power supply line 81, a grounding line 82, and a control line 83, which are connected to the lamp 3 from the outside. Further, the terminal, the wiring holder, the socket, and the like for connecting these wirings are also used as the wiring material 85. In FIG. 6, the power supply line 81, the ground line 82, and the control line 83 connected to the lamp 3 are shown as the wiring material 85. The wiring material 85 may be arranged in the wiring region in the mounting portion 25 in a state where each wiring wrapped with the insulating material is bundled with a coating or bundled with a binding band. Further, each wiring may be arranged in a wiring region in the mounting portion 25 in a state of being separated from each other.

実施の形態１においては、配線材８５が、透光性カバー３０に接触するものとして説明する。ただし、配線材８５だけでなく、たとえば、施工場所に設けられる、灯具３外の送り配線および調光線等の電線材についても、配線領域内に配置されることで、被覆が接触する可能性がある。図示は省略するが、実施の形態１においては、透光性カバー３０は、灯具３から照射される光を妨げない領域であって、配線材８５の被覆が接触する可能性がある部分に可塑剤遮断部が設けられてもよい。 In the first embodiment, the wiring material 85 will be described as being in contact with the translucent cover 30. However, not only the wiring material 85, but also, for example, the electric wire material such as the feed wiring outside the lamp 3 and the light control light provided at the construction site may come into contact with the coating by being arranged in the wiring area. is there. Although not shown, in the first embodiment, the translucent cover 30 is a region that does not block the light emitted from the lamp 3, and is plasticized in a portion where the coating of the wiring material 85 may come into contact. An agent blocking portion may be provided.

図示は省略するが、透光性カバー３０は、異なる材料を用いた複数の層からなる積層構造としてもよい。積層構造は、異種材料を用いた多色成形、塗布、或いは噴霧による基材表面に対する膜形成、基材表面に対する膜貼合等の方法によって形成することができる。この際、発光部６０に近い層である内側層は、耐衝撃性、耐熱性、難燃性の面で優れた材料を用いて形成されることが好ましく、照射空間に近い層である外側層は、耐水性、耐薬品性、防汚性、帯電防止性、吸水率管理の面で優れた材料を用いて形成されることが好ましい。 Although not shown, the translucent cover 30 may have a laminated structure composed of a plurality of layers using different materials. The laminated structure can be formed by a method such as multicolor molding using different materials, coating, or spraying to form a film on the surface of the base material, or bonding the film to the surface of the base material. At this time, the inner layer, which is a layer close to the light emitting portion 60, is preferably formed by using a material having excellent impact resistance, heat resistance, and flame retardancy, and is an outer layer which is a layer close to the irradiation space. Is preferably formed using a material having excellent water resistance, chemical resistance, stain resistance, antistatic property, and water absorption rate control.

透光性カバー３０は、たとえば、耐衝撃性に優れた材料を用いて内側層を形成した場合、発光部６０を透光性カバー３０の内部に収容する際に接触しても、損傷しにくくなる。また、たとえば、透光性カバー３０は、難燃性に優れた材料を用いて内側層を形成した場合、発光部６０由来の万が一の発火に際して、外部への類焼を防止することができる。 When the inner layer of the translucent cover 30 is formed of, for example, a material having excellent impact resistance, the translucent cover 30 is not easily damaged even if it comes into contact with the light emitting portion 60 when it is housed inside the translucent cover 30. Become. Further, for example, when the inner layer of the translucent cover 30 is formed by using a material having excellent flame retardancy, it is possible to prevent burning to the outside in the unlikely event of ignition from the light emitting portion 60.

透光性カバー３０は、たとえば、加水分解が主鎖に及ばない材料を用いて外側層を形成した場合、或いは、吸水率が低い成分を用いて外側層を形成した場合、内側層には加水分解が進行しにくく、長期に渡って発光部６０を保護する機能が保たれる。また、透光性カバー３０は、吸水率が高い成分を用いて外側層を形成した場合、発光部６０の動作熱の影響を受ける内側層の熱膨張量と吸水の影響を受ける外側層の吸水膨張量とをバランスさせることができるため、内側層と外側層とが剥離しにくくなる。 When the outer layer is formed by using a material whose main chain is not hydrolyzed, or when the outer layer is formed by using a component having a low water absorption rate, the translucent cover 30 has water added to the inner layer. Decomposition does not proceed easily, and the function of protecting the light emitting unit 60 is maintained for a long period of time. Further, when the outer layer of the translucent cover 30 is formed by using a component having a high water absorption rate, the amount of thermal expansion of the inner layer affected by the operating heat of the light emitting portion 60 and the water absorption of the outer layer affected by water absorption. Since the amount of expansion can be balanced, the inner layer and the outer layer are less likely to separate.

透光性カバー３０は、たとえば、発光部６０に近い層としてポリカーボネイト（ＰＣ）を主成分とする材料を用いて筒形部材を形成し、筒形部材における照射空間の側の表面にアクリル（ＰＭＭＡ）を主成分とする膜を形成した、異種材料積層構造とすることができる。 The translucent cover 30 forms, for example, a tubular member using a material containing polycarbonate (PC) as a main component as a layer close to the light emitting portion 60, and acrylic (PMMA) is formed on the surface of the tubular member on the irradiation space side. ) Can be formed into a film having a different material layered structure.

さらに、図示は省略するが、透光性カバー３０の形状を安定させることまたは剛性を向上させること等を目的として、一組の並行部３１において、それぞれ長手方向Ｘに渡るリブが設けられるようにしてもよい。この際、リブは、灯具３が照明器具２に装着された状態で、器具側面部２２におけるカール部２２３付近と対向するような位置に形成される。ここで、透光性カバー３０が、後述する端部カバー４０と嵌合できるように、リブは、端部３６の外面部には形成されない。 Further, although not shown, ribs extending in the longitudinal direction X are provided in each of the pair of parallel portions 31 for the purpose of stabilizing the shape of the translucent cover 30 or improving the rigidity. You may. At this time, the rib is formed at a position facing the vicinity of the curl portion 223 on the side surface portion 22 of the fixture with the lamp 3 attached to the lighting fixture 2. Here, the rib is not formed on the outer surface portion of the end portion 36 so that the translucent cover 30 can be fitted with the end cover 40 described later.

そして、図４に示すように、透光性カバー３０は、取付部材５０に配置された発光素子６１の発光面を覆うと共に、取付部材５０の長手方向に沿った長手方向Ｘとなる第１方向における端部３６に、開口が形成されている。換言すれば、透光性カバー３０は、少なくとも一方の端部３６が開口する長尺形状の中空体であると共に、発光素子６１が実装された基板６２を内部に収容する。カバー端部３５は、透光性カバー３０の長手方向Ｘにおいて、透光性カバー３０の両端部分である。透光性カバー３０のカバー端部３５には、端部３６が設けられている。端部３６は、カバー端部３５において端部カバー４０が嵌合される部分であり、端部蓋である端部カバー４０に覆われる部分である。端部３６は、透光性カバー３０の伸縮に伴い、端部カバー４０と共に長手方向Ｘである第１方向に沿って移動自在な自由端である。厳密には、透光性カバー３０の端部３６および端部カバー４０は、「長手方向Ｘ」以外の方向にも伸縮するものであるが、実施の形態に係る灯具３においては、透光性カバー３０は「長手方向Ｘ」の伸縮を許容する構造（構成）を有するものとする。図４および図６に示すように、透光性カバー３０の外周部３７は、一組の並行部３１、第１接続部３２および第２接続部３３となる外殻部の外面側である。また、内周部３８は、一組の並行部３１、第１接続部３２および第２接続部３３となる外殻部の内面側である。 Then, as shown in FIG. 4, the translucent cover 30 covers the light emitting surface of the light emitting element 61 arranged on the mounting member 50, and is in the first direction X along the longitudinal direction of the mounting member 50. An opening is formed at the end portion 36 of the above. In other words, the translucent cover 30 is a long hollow body in which at least one end 36 is open, and houses a substrate 62 on which a light emitting element 61 is mounted. The cover end portions 35 are both end portions of the translucent cover 30 in the longitudinal direction X of the translucent cover 30. An end portion 36 is provided at the cover end portion 35 of the translucent cover 30. The end portion 36 is a portion where the end cover 40 is fitted in the cover end portion 35, and is a portion covered by the end cover 40 which is an end lid. The end portion 36 is a free end that can move along with the end cover 40 along the first direction, which is the longitudinal direction X, as the translucent cover 30 expands and contracts. Strictly speaking, the end portion 36 and the end portion cover 40 of the translucent cover 30 expand and contract in a direction other than the "longitudinal direction X", but in the lamp 3 according to the embodiment, the translucent property is used. The cover 30 shall have a structure (configuration) that allows expansion and contraction in the "longitudinal direction X".

The engaging piece insertion hole 461 has a small amount of extension of the translucent cover 30, that is, a small amount of movement of the second cover engaging piece 422 and the second cover engaging claw 423, or the end cover 40 It is not necessary when it is integrally formed, and it is not an essential configuration of the lamp 3.

係合部４７は、固定部４６において、上方側（Ｚ１側）の端部から長手方向Ｘ（第１方向）における中央側（Ｘ２側）に延びた部分である。すなわち、係合部４７は、固定部４６の上縁部から突出する板状の部材である。係合部４７は、端部カバー４０と係合した状態において、端部カバー４０側に突出しており、灯具３において、灯具３の上方側（Ｚ１側）に配置される。 The engaging portion 47 is a portion of the fixed portion 46 extending from the end portion on the upper side (Z1 side) to the central side (X2 side) in the longitudinal direction X (first direction). That is, the engaging portion 47 is a plate-shaped member protruding from the upper edge portion of the fixing portion 46. The engaging portion 47 projects toward the end cover 40 in a state of being engaged with the end cover 40, and is arranged on the upper side (Z1 side) of the lamp 3 in the lamp 3.

上述したように、連結部材４４には、電源線８１、接地線８２、制御線８３等の電線を通過させる電線挿通孔４７０がスリット状に形成されている。係合部４７に形成されている電線挿通孔４７０を上部スリット４７１０と称する。上部スリット４７１０は、灯具３の長手方向Ｘに沿って形成されている。上部スリット４７１０は、固定部４６に形成された端部スリット４７１１と繋がっている。上部スリット４７１０は、透光性カバー３０の端部３６および端部カバー４０を、長手方向Ｘ（第１方向）の移動が規制されない自由端とするために、連結部材４４の係合部４７に形成されたスリットである。上部スリット４７１０には、後述する挿入孔４７２から挿入されるカバー電線保持部４１６が、短手方向Ｙおよび上下方向Ｚに移動が規制された状態で係合する。なお、挿入孔４７２に配置されるカバー電線保持部４１６は、長手方向Ｘ（第１方向）には移動が規制されない。上部スリット４７１０に、カバー電線保持部４１６が係合した状態では、連結部材４４の端部カバー４０に対する位置が決まるので、固定ネジ７５を用いて連結部材４４をボス部５７に固定する際に固定ネジ７５の位置合わせがしやすくなる。電源線８１、接地線８２、制御線８３の全てまたは一部を編組チューブ等で束線した状態では、一般的に硬くなり曲がり難くなる。しかし、連結部材４４は、上部スリット４７１０と繋がるように形成された端部スリット４７１１を有することにより、電源線８１等が束線されて曲がり難くなっても、配線がし易くなる。 As described above, the connecting member 44 is formed with a slit-shaped electric wire insertion hole 470 through which the electric wires such as the power supply line 81, the grounding wire 82, and the control line 83 pass. The electric wire insertion hole 470 formed in the engaging portion 47 is referred to as an upper slit 4710. The upper slit 4710 is formed along the longitudinal direction X of the lamp 3. The upper slit 4710 is connected to the end slit 4711 formed in the fixing portion 46. The upper slit 4710 fits into the engaging portion 47 of the connecting member 44 so that the end 36 and the end cover 40 of the translucent cover 30 are free ends where movement in the longitudinal direction X (first direction) is not restricted. It is a formed slit. The cover wire holding portion 416 inserted from the insertion hole 472, which will be described later, engages with the upper slit 4710 in a state where movement is restricted in the lateral direction Y and the vertical direction Z. The movement of the cover electric wire holding portion 416 arranged in the insertion hole 472 is not restricted in the longitudinal direction X (first direction). When the cover electric wire holding portion 416 is engaged with the upper slit 4710, the position of the connecting member 44 with respect to the end cover 40 is determined. Therefore, the connecting member 44 is fixed to the boss portion 57 by using the fixing screw 75. It becomes easy to align the screw 75. When all or part of the power line 81, the ground line 82, and the control line 83 are bundled with a braided tube or the like, they are generally hard and difficult to bend. However, since the connecting member 44 has the end slit 4711 formed so as to be connected to the upper slit 4710, even if the power supply line 81 or the like is bundled and becomes difficult to bend, wiring becomes easy.

係合部４７には、後述するカバー電線保持部４１６が挿入される挿入孔４７２が形成されている。挿入孔４７２は、上部スリット４７１０と連続して形成されている。挿入孔４７２は、固定部４６に形成されている貫通孔であり、上部スリット４７１０の長手方向Ｘ（第１方向）における中央側（Ｘ２側）と繋がって形成されている。挿入孔４７２は、カバー電線保持部４１６が挿入可能な形状および寸法で形成されている。挿入孔４７２から挿入されたカバー電線保持部４１６は、透光性カバー３０の伸長に応じて、上部スリット４７１０と係合した状態で、長手方向Ｘに沿って移動する。そのためカバー電線保持部４１６は、透光性カバー３０の伸縮、および透光性カバー３０の伸縮に伴う端部カバー４０および封止具４３の移動を妨げない。 The engaging portion 47 is formed with an insertion hole 472 into which the cover electric wire holding portion 416, which will be described later, is inserted. The insertion hole 472 is formed continuously with the upper slit 4710. The insertion hole 472 is a through hole formed in the fixing portion 46, and is formed by being connected to the central side (X2 side) in the longitudinal direction X (first direction) of the upper slit 4710. The insertion hole 472 is formed in a shape and size into which the cover electric wire holding portion 416 can be inserted. The cover wire holding portion 416 inserted from the insertion hole 472 moves along the longitudinal direction X in a state of being engaged with the upper slit 4710 in accordance with the extension of the translucent cover 30. Therefore, the cover wire holding portion 416 does not hinder the expansion and contraction of the translucent cover 30 and the movement of the end cover 40 and the sealant 43 due to the expansion and contraction of the translucent cover 30.

As shown in FIG. 6, the light emitting unit 60 includes a light emitting element 61, a substrate 62, and the like. The light emitting element 61 emits light by supplying electric power. In the first embodiment, a light emitting diode (Light Emitting Diode; hereinafter referred to as an LED) element is used as the light emitting element 61, and the mounting surface of the substrate 62 is formed in a row shape, a staggered shape, or the like along the longitudinal direction X. Is implemented in. The light emitting element 61 of the first embodiment is packaged by arranging a phosphor that converts blue light into yellow light on an LED chip that emits blue light having a wavelength of 440 to 480 [nm]. It is a pseudo-white LED element that is a surface mount component. Here, the light emitted by the light emitting element 61 has the maximum luminous flux value, and spreads by the irradiation angle α symmetrically with respect to the optical axis perpendicular to the light emitting surface. In the lighting device 1 of the first embodiment, the irradiation angle α of the light emitting element 61 is assumed to be 120 degrees. As the light emitting element 61, a solid-state laser (Solid State Laser), a semiconductor laser (Semiconducor Laser), an organic EL (Electro Luminescence), an inorganic EL, or the like may be used. As the substrate 62, a glass-epoxy substrate (FR-4), a glass-composite substrate (CEM-3), a paper epoxy substrate (FR-3), a paper phenol substrate (XPC), a metal base substrate and the like are used.

制御部８０は、電源装置であり、外部から供給される電力から発光素子６１を点灯させる電力に変換して、発光素子６１に供給する。実施の形態１の照明装置１では、制御部８０は、前述したように、台座５１の取付面部５２の裏面に、ネジ（図示は省略）等の固定部材を用いて取り付けられた状態で、発光素子６１等と共に筒状の透光性カバー３０に収容されている。ただし、制御部８０は、灯具３ではなく、照明器具２に取り付けられる構成であってもよい。この場合、電線は、制御部８０から発光素子６１に供給される電力の供給経路として機能する給電線となる。実施の形態１の照明装置１における電源線８１、接地線８２および制御線８３等の電線は、一端は、制御部８０に接続される。そして、電線の他端は、照明器具２に取り付けられている端子台（図示は省略）に接続される。 The control unit 80 is a power supply device, converts electric power supplied from the outside into electric power for lighting the light emitting element 61, and supplies the electric power to the light emitting element 61. In the lighting device 1 of the first embodiment, as described above, the control unit 80 emits light in a state of being attached to the back surface of the attachment surface portion 52 of the pedestal 51 by using a fixing member such as a screw (not shown). It is housed in a tubular translucent cover 30 together with the element 61 and the like. However, the control unit 80 may be attached to the luminaire 2 instead of the lamp 3. In this case, the electric wire becomes a feeder function as a supply path of electric power supplied from the control unit 80 to the light emitting element 61. One end of the electric wires such as the power supply line 81, the ground wire 82, and the control line 83 in the lighting device 1 of the first embodiment is connected to the control unit 80. The other end of the electric wire is connected to a terminal block (not shown) attached to the luminaire 2.

ここで、図６において、Ｐ１は、器具底面部２１と器具側面部２２との境界となる器具側面部２２が折り曲がって立ち上がった部分における内側の部分である。距離Ｗ４は、一組の器具側面部２２における２つのＰ１の間の距離であり、短手方向Ｙにおける器具底面部２１の幅となる。そして、距離Ｗ５は、一組の器具側面部２２におけるカール部２２３の内側に巻かれた部分の端部間の距離である。 Here, in FIG. 6, P1 is an inner portion in a portion where the instrument side surface portion 22 which is a boundary between the instrument bottom surface portion 21 and the instrument side surface portion 22 is bent and stands up. The distance W4 is the distance between two P1s on the side surface portion 22 of the instrument, and is the width of the bottom surface portion 21 of the instrument in the lateral direction Y. The distance W5 is the distance between the ends of the curl portion 223 of the set of instrument side surface portions 22 that are wound inside.

また、Ｐ２は、第２側面部２２１の折り曲げ部分である。距離Ｗ１は、一組の器具側面部２２における２つのＰ２間の距離である。さらに、Ｐ３は、器具側面部２２における下端部分となる。ここでは、Ｐ３は、開口端部２６の位置となる。距離Ｗ２は、一組の器具側面部２２における２つのＰ３間の距離である。また、Ｐ４は、カール部２２３において、短手方向Ｙ（第２方向）の最も内側に位置する側面最狭部である。距離Ｗ３は、一組の器具側面部２２における２つのＰ４間の距離である。ここで、距離Ｗ１、距離Ｗ２および距離Ｗ３は、Ｗ１＞Ｗ２＞Ｗ３の関係にある。そして、Ｐ６は、透光性カバー３０の外周部３７において、一組の器具側面部２２における側面最狭部Ｐ４と対向し、透光性カバー３０の短手方向Ｙにおける幅が最も広いカバー最広部である。ここでは、Ｐ６は、外周部３７の並行部３１の部分となる。距離Ｗ６は、２つのカバー最広部Ｐ６間の距離である。 Further, P2 is a bent portion of the second side surface portion 221. The distance W1 is the distance between two P2s on a set of instrument side surfaces 22. Further, P3 is a lower end portion of the instrument side surface portion 22. Here, P3 is the position of the opening end portion 26. The distance W2 is the distance between two P3s on a set of instrument side surfaces 22. Further, P4 is the narrowest side surface portion of the curl portion 223 located on the innermost side in the lateral direction Y (second direction). The distance W3 is the distance between the two P4s in the set of instrument side surfaces 22. Here, the distance W1, the distance W2, and the distance W3 have a relationship of W1> W2> W3. Then, P6 faces the narrowest side surface portion P4 of the set of instrument side surface portions 22 on the outer peripheral portion 37 of the translucent cover 30, and is the widest cover maximum in the lateral direction Y of the translucent cover 30. It is a wide area. Here, P6 is a portion of the parallel portion 31 of the outer peripheral portion 37. The distance W6 is the distance between the two widest covers P6.

図６および図７に示すように、灯具３が照明器具２の装着部２５に装着された状態において、透光性カバー３０の外周部３７は、照明器具２と最も近接する部分となる。外周部３７の並行部３１におけるカバー最広部Ｐ６とカール部２２３の側面最狭部Ｐ４とは、寸法Ｔ２の隙間を有し、対向して配置される。ここで、寸法Ｔ２は、（距離Ｗ３−距離Ｗ６）／２となる。また、開口端部２６となるＰ３は、短手方向Ｙにおいて側面最狭部Ｐ４よりも外側に位置する。 As shown in FIGS. 6 and 7, when the lamp 3 is mounted on the mounting portion 25 of the lighting fixture 2, the outer peripheral portion 37 of the translucent cover 30 is the portion closest to the lighting fixture 2. The widest cover portion P6 in the parallel portion 31 of the outer peripheral portion 37 and the narrowest side portion P4 of the curl portion 223 have a gap of dimension T2 and are arranged so as to face each other. Here, the dimension T2 is (distance W3-distance W6) / 2. Further, P3, which is the opening end portion 26, is located outside the narrowest side portion P4 in the lateral direction Y.

したがって、実施の形態１の照明装置１では、カバー最広部Ｐ６は、短手方向Ｙにおいて、開口端部２６が位置するＰ３とも離れた位置にある。このため、カバー最広部を有する透光性カバー３０の並行部３１における外周部３７と側面最狭部を有するカール部２２３（特に開口端部２６）とは、上下方向Ｚから見たときに、重ならない位置関係にある。このため、図７の実線矢印で示すように、器具本体２０における器具側面部２２の外面に付着し、流下した流体は、器具側面部２２において下端である開口端部２６から下方に滴下する。透光性カバー３０の外周部３７と器具側面部２２の開口端部２６は、上下方向Ｚにおいて重なっていない位置関係にあるため、開口端部２６から流下した流体は、外周部３７には滴下しない。このため、流体が流下しても、灯具３を構成する外郭である透光性カバー３０には付着しない。 Therefore, in the lighting device 1 of the first embodiment, the widest cover portion P6 is located at a position away from P3 where the opening end portion 26 is located in the lateral direction Y. Therefore, the outer peripheral portion 37 and the curl portion 223 (particularly the opening end portion 26) having the narrowest side surface portion of the parallel portion 31 of the translucent cover 30 having the widest portion of the cover are viewed from the vertical direction Z. , There is a positional relationship that does not overlap. Therefore, as shown by the solid arrow in FIG. 7, the fluid adhering to the outer surface of the instrument side surface portion 22 of the instrument body 20 and flowing down is dropped downward from the opening end portion 26 which is the lower end of the instrument side surface portion 22. Since the outer peripheral portion 37 of the translucent cover 30 and the open end portion 26 of the instrument side surface portion 22 are not overlapped in the vertical direction Z, the fluid flowing down from the open end portion 26 drops on the outer peripheral portion 37. do not do. Therefore, even if the fluid flows down, it does not adhere to the translucent cover 30 which is the outer shell constituting the lamp 3.

また、側面最狭部Ｐ４であるカール部２２３とカバー最広部Ｐ６である外周部３７の並行部３１とは、寸法Ｔ２の隙間を有し、対向して配置される。ここで、寸法Ｔ２は、（距離Ｗ３−距離Ｗ６）／２となる。このため、図７の破線矢印で示すように、透光性カバー３０の外周部３７において、装着部２５に収容されている部分に付着し、流下した流体は、寸法Ｔ２の隙間を介して並行部３１を流下する。したがって、流体が装着部２５の内部に滞留することおよび装着部２５に滞留した流体が乾燥固化することを抑制できる。ここで、照明装置１を下方から見上げたときに、照明器具２（カール部２２３）と灯具３（並行部３１）との境界は、黒スジ状の線となって見えることになる。そこで、側面最狭部Ｐ４であるカール部２２３とカバー最広部Ｐ６である並行部３１との隙間の寸法Ｔ２は、黒スジ状の線が目立たなくなるような寸法であることが好ましい。そこで、隙間の寸法Ｔ２が、たとえば、０．５ｍｍ以上１．０ｍｍ以下の寸法になるようにする。 Further, the curl portion 223, which is the narrowest side portion P4, and the parallel portion 31 of the outer peripheral portion 37, which is the widest cover portion P6, have a gap of dimension T2 and are arranged so as to face each other. Here, the dimension T2 is (distance W3-distance W6) / 2. Therefore, as shown by the broken line arrow in FIG. 7, the fluid adhering to the portion of the outer peripheral portion 37 of the translucent cover 30 accommodated in the mounting portion 25 and flowing down is parallel through the gap of dimension T2. The part 31 flows down. Therefore, it is possible to prevent the fluid from staying inside the mounting portion 25 and the fluid staying in the mounting portion 25 from drying and solidifying. Here, when the lighting device 1 is looked up from below, the boundary between the lighting fixture 2 (curl portion 223) and the lighting fixture 3 (parallel portion 31) appears as a black streak-like line. Therefore, it is preferable that the dimension T2 of the gap between the curl portion 223, which is the narrowest side portion P4, and the parallel portion 31, which is the widest cover portion P6, is such that the black streak-shaped lines are inconspicuous. Therefore, the gap dimension T2 is set to, for example, 0.5 mm or more and 1.0 mm or less.

また、カール部２２３は、前述したように、カール部２２３の端部と器具側面部２２の内面側とが、侵入口２２５となる隙間を有する。侵入口２２５となる隙間の寸法Ｔ１は、（距離Ｗ４−距離Ｗ５）／２となる。図７の破線矢印で示すように、器具本体２０の器具側面部２２の内面に付着し、流下した流体は、侵入口２２５を介して、カール部２２３の捕捉溝２２４に捕捉される。したがって、流下した流体は、灯具３を構成する外郭である透光性カバー３０に付着および滴下しない。 Further, as described above, the curl portion 223 has a gap between the end portion of the curl portion 223 and the inner surface side of the instrument side surface portion 22 as an entry port 225. The dimension T1 of the gap serving as the entrance 225 is (distance W4-distance W5) / 2. As shown by the broken line arrow in FIG. 7, the fluid adhering to the inner surface of the instrument side surface portion 22 of the instrument body 20 and flowing down is captured by the trapping groove 224 of the curl portion 223 via the entry port 225. Therefore, the flowing fluid does not adhere to and drip on the translucent cover 30, which is the outer shell constituting the lamp 3.

ここで、図示は省略するが、たとえば、カール部２２３の下端である開口端部２６に貫通孔を設け、捕捉溝２２４に捕捉された流体を、貫通孔を介して、下方に排出させるようにしてもよい。カール部２２３の下端に貫通孔を設け、捕捉溝２２４内の流体を排出することで、捕捉溝２２４に捕捉された流体が、侵入口２２５となる寸法Ｔ１の隙間から溢れ出し、灯具３を構成する外郭である透光性カバー３０に付着することを防止することができる。 Although not shown here, for example, a through hole is provided in the opening end portion 26 which is the lower end of the curl portion 223 so that the fluid captured in the capture groove 224 is discharged downward through the through hole. You may. By providing a through hole at the lower end of the curl portion 223 and discharging the fluid in the capture groove 224, the fluid captured in the capture groove 224 overflows from the gap of the dimension T1 which becomes the entry port 225, and constitutes the lamp tool 3. It is possible to prevent the cover 30 from adhering to the translucent cover 30 which is the outer shell.

以上のように、実施の形態１によれば、照明装置１が、灯具３の最広部となる透光性カバー３０における外周部３７と、最狭部となる照明器具２の器具側面部２２において開口面側の端部となるカール部２２３（開口端部２６）とは、鉛直方向である上下方向Ｚにおいて重ならない位置関係にある構成にする。このため、照明器具２から流下する流体が、灯具３が有する透光性カバー３０に滴下しない。したがって、透光性カバー３０への異物付着等を防止し、透光性カバー３０の劣化を防止することができる。そして、一対の器具側面部２２の距離が、短手方向Ｙにおける器具底面部２１の最小幅以下であるため、さらに、透光性カバー３０への流体の滴下を防止することができる。 As described above, according to the first embodiment, the lighting device 1 has an outer peripheral portion 37 of the translucent cover 30 which is the widest portion of the lamp 3 and a fixture side surface portion 22 of the lighting fixture 2 which is the narrowest portion. The curl portion 223 (opening end portion 26), which is the end portion on the opening surface side, is configured to have a positional relationship that does not overlap in the vertical direction Z in the vertical direction. Therefore, the fluid flowing down from the luminaire 2 does not drip onto the translucent cover 30 of the luminaire 3. Therefore, it is possible to prevent foreign matter from adhering to the translucent cover 30 and prevent deterioration of the translucent cover 30. Since the distance between the pair of instrument side surface portions 22 is equal to or less than the minimum width of the instrument bottom surface portion 21 in the lateral direction Y, it is possible to further prevent the fluid from dripping onto the translucent cover 30.

The lighting fixture 2a has a fixture body 20a on which a set of fixture side surface portions 22a is formed.

以上のように、実施の形態２の照明装置１においては、器具側面部２２ａが傾斜平面を有する形状であるため、折り曲げ部分を少なくし、意匠性を向上させることができる。また、実施の形態３では、折り曲げ部分を少なくすることで、照明器具２ａの製造の際の加工を簡単にし、手順を軽減することができる。 As described above, in the lighting device 1 of the second embodiment, since the fixture side surface portion 22a has a shape having an inclined plane, it is possible to reduce the number of bent portions and improve the design.

Further, since there is no gap between the curl portion 223 of the lighting fixture 2 and the outer peripheral portion 37 of the translucent cover 30, it is possible to suppress the intrusion of foreign matter or the like into the inside of the mounting portion 25.

実施の形態６．
実施の形態５の照明装置１では、照明器具２のカール部２２３と灯具３の透光性カバー３０における外周部３７とが当接する態様について説明した。このとき、当接部分において、カール部２２３が、透光性カバー３０の並行部３１を押圧するようにしてもよい。 Embodiment 6.
In the lighting device 1 of the fifth embodiment, a mode in which the curl portion 223 of the lighting fixture 2 and the outer peripheral portion 37 of the translucent cover 30 of the lamp 3 come into contact with each other has been described. At this time, the curl portion 223 may press the parallel portion 31 of the translucent cover 30 at the contact portion.

カール部２２３は、透光性カバー３０の並行部３１との当接部分において、透光性カバー３０の変形を矯正するように作用する。このため、透光性カバー３０に変形が残っていても、カール部２２３と透光性カバー３０の並行部３１との間に隙間が発生しない。このため、意匠性を向上させることができ、装着部２５の内部への異物等の侵入を抑制することができる。そして、透光性カバー３０単体で変形が許容されることによって、透光性カバー３０の製造上の歩留まりを向上させることができる。また、透光性カバー３０を薄肉化することができ、使用する材料の削減、透光性カバー３０および灯具３の軽量化に繋がる効果を期待することができる。 The curl portion 223 acts to correct the deformation of the translucent cover 30 at the contact portion of the translucent cover 30 with the parallel portion 31. Therefore, even if the translucent cover 30 remains deformed, no gap is generated between the curl portion 223 and the parallel portion 31 of the translucent cover 30. Therefore, the design can be improved, and the invasion of foreign matter or the like into the mounting portion 25 can be suppressed. Then, since the translucent cover 30 alone is allowed to be deformed, the manufacturing yield of the translucent cover 30 can be improved. In addition, the translucent cover 30 can be made thinner, and the effect of reducing the materials used and reducing the weight of the translucent cover 30 and the lamp 3 can be expected.
