Description

This technology relates to lamp mounting fixtures, lighting devices, and corrective devices. In particular, it relates to the dimensional control of openings in lamp mounting fixtures.

Some lighting devices include a lamp having a light source covered by a cover, and a lamp mounting device to which the lamp is attached and which is attached to a wall or other target surface. In some such lighting devices, a protrusion provided on the lower end of the side wall of the lamp mounting device reduces the gap between the lamp and the lamp mounting device, minimizing the decrease in brightness at the boundary between the lamp and the lamp mounting device while also reducing the size of the lamp mounting device (see, for example, Patent Document 1).

Patent No. 6481941

The lamp mounting device of Patent Document 1 mentioned above allows high precision control of the opening dimensions at both longitudinal ends of the device body by using second side walls attached to both longitudinal ends of the device body. However, it is difficult to achieve high precision control of the opening dimensions in parts of the device body other than both longitudinal ends (particularly the central part). Also, in the lamp mounting device of Patent Document 1, there is a risk that the protruding pieces may damage the case of the light source unit, deteriorate the design, and hinder installation.

In view of the above problems, the objective is to provide a lamp mounting device, lighting equipment, and orthodontic device that can precisely control the opening dimensions throughout the entire device body.

The lamp mounting device disclosed here is a lamp mounting device on which a lamp having a light source is mounted, and comprises a fixture main body having a fixture top surface portion arranged along an attachment object and a fixture side surface portion rising from the fixture top surface portion in a direction intersecting with the fixture top surface portion, and a correction device having a base attached to the fixture top surface portion and a correction portion rising from the base in a direction intersecting with the base, wherein when the base is attached to the fixture top surface portion, the correction device corrects the fixture side surface portion so that the molding angle formed by the fixture top surface portion and the fixture side surface portion of the fixture main body portion becomes the correction angle formed by the base and the correction portion , and when the base is attached to the fixture top surface portion, the correction portion and the fixture side surface portion are at least partially separated .

The lighting device disclosed herein includes the above-mentioned lamp mounting device and a lamp that is attached to the lamp mounting device.

The corrective device disclosed herein is a corrective device that is attached to an instrument main body having an instrument top surface portion that is arranged along the attachment object and an instrument side surface portion that rises from the instrument top surface portion in a direction intersecting with the instrument top surface portion, and comprises a base that is attached to the instrument top surface portion, and a corrective portion that rises from the base in a direction intersecting with the base, and when the base is attached to the instrument top surface portion, the instrument side surface portion is corrected so that the molding angle formed by the instrument top surface portion and the instrument side surface portion of the instrument main body portion becomes the correction angle formed by the base and the corrective portion , and when the base is attached to the instrument top surface portion, the corrective portion and the instrument side surface portion are at least partially separated .

The lamp mounting device and the like disclosed herein is provided with a correction tool that is attached to the device main body. The device side surface of the device main body is corrected so that the molding angle between the device top surface and the device side surface of the device main body is the correction angle between the base of the correction tool and the correction portion. This allows the opening dimensions of the device main body to be controlled with high precision.

<Configuration of lighting device 1>
The configuration of the lighting device 1 according to the first embodiment will be described with reference to FIGS. 1 to 16. In the following description, the direction along the long side of the lighting device 1 is the long direction X, which is the first direction. Furthermore, the direction perpendicular to the long direction X and along the short side relative to the long direction X is the short direction Y, which is the second direction. Furthermore, the direction perpendicular to both the long direction X and the short direction Y is the up-down direction Z, which is the third direction. Here, the up-down direction Z in the first embodiment is the vertical direction. Furthermore, in the long direction X, the direction toward the long end side is the end direction X1. Furthermore, the direction opposite to the end direction X1 and toward the longitudinal center side is the inward direction X2. Furthermore, in the up-down direction Z, the direction toward the side of the construction part 9 to which the lighting device 1 is attached (for example, the ceiling or wall side) is the upward direction Z1. Furthermore, the direction opposite to the upward direction Z1 and toward the irradiation space side to which light is irradiated from the lighting device 1 is the downward direction Z2. Here, the upward direction Z1 is the direction in which the lamp 3 is attached to the lamp mounting fixture 2. The downward direction Z2 is the direction in which the lamp 3 is removed from the lamp mounting fixture 2.

As shown in FIG. 1, the lighting device 1 in the first embodiment has a lamp mounting fixture 2 that is attached to a structure 9 such as a ceiling or a wall, and a lamp 3 that is attached to the lamp mounting fixture 2. In the first embodiment, the lamp mounting fixture 2 in a so-called trough-type lighting device 1 is shown as an example.

<Lamp mounting device 2>
The lamp mounting device 2 is a housing in which the lamp 3 is attached. The lamp mounting device 2 is also called a lighting device. The lamp mounting device 2 has a device main body 20, a device end portion 23, and a correction device 29.

The fixture main body 20 has a fixture top surface 21 and a pair of fixture side surfaces 22. The fixture top surface 21 is an attachment part that is arranged along the construction part 9 to which the fixture is to be attached, such as a ceiling. The fixture top surface 21 is long in the longitudinal direction X, and is formed in a flat plate shape that extends in the longitudinal direction X and the lateral direction Y, facing an opening surface described later. The fixture top surface 21 is also called the fixture bottom surface. The fixture top surface 21 has a minimum width that is the distance between the side edges in the lateral direction Y. The pair of fixture side surfaces 22 are arranged at both ends of the fixture top surface 21 in the lateral direction Y. In the first embodiment, the fixture main body 20 is formed by bending a metal plate material by pressing or rolling. The fixture main body 20 may be formed by a processing method such as extrusion molding or three-dimensional modeling.

In the first embodiment, as shown in FIG. 4 and the like, the lamp mounting device 2 is attached to the construction part 9 by a fastener such as a hanging bolt 90 provided on the construction part 9 and a nut 91 tightened onto the hanging bolt 90. The fixture top surface part 21 has an insertion hole (not shown) through which the hanging bolt 90 used to fix the lamp mounting device 2 to the construction part 9 is inserted. The fixture top surface part 21 also has a power line inlet hole for drawing in an external power line (not shown) connected to an external power source such as a commercial power source. Furthermore, the fixture top surface part 21 has a through hole such as a screw hole 210 into which a mounting screw 76 for fixing the correction tool 29 is screwed. The fixture body part 20 is provided with a terminal block (not shown) to which the external power line is connected.

The fixture ends 23 are disposed at both ends of the fixture top surface 21 in the longitudinal direction X. Two fixture ends 23 form a pair. As shown in FIG. 2 and other figures, the fixture ends 23 have end covers 24 formed by knockout processing, which cover the end holes. The end holes can be used, for example, as through holes for passing wiring leading from adjacent lighting devices, for example, when multiple lighting devices 1 are connected and installed along the longitudinal direction X.

The mounting section 25 is formed into a concave shape (box shape) with an opening on one side facing the top surface 21 by the top surface 21 of the main body 20, a set of side surfaces 22, and a set of end portions 23. Therefore, the mounting section 25 forms a space surrounded by the top surface 21 of the main body 20, a set of side surfaces 22, and a set of end portions 23.

The mounting section 25 is the portion where the lamp 3 is mounted, and serves as a housing section that houses a portion of the mounted lamp 3. The portion of the lamp 3 housed in the mounting section 25 serves as a non-illuminating portion that is not the illuminating side. In addition, the portion of the mounting section 25 that is not occupied by the lamp 3 when the lamp 3 is housed therein serves as a wiring area through which the wiring material 85 (described later) and the like are arranged when they are connected to the lamp 3.

The pair of side surfaces 22 are peripheral walls of the mounting portion 25 in the longitudinal direction X, and are side walls that rise in pairs with the side edges of the top surface 21 as base ends so as to be parallel to the longitudinal direction X of the top surface 21. The side surfaces 22 have a first side surface 220 that rises substantially perpendicular to the top surface 21, and a second side surface 221 that slopes inward in the lateral direction Y from a bent portion 222 that is the lower end of the first side surface 220. Here, in the pair of side surfaces 22, the distance between the first side surfaces 220 is the same as the distance between the side edges that are the minimum width of the top surface 21 in the lateral direction Y. The distance between the second side surfaces 221 is shorter than the distance between the side edges of the top surface 21 in the lateral direction Y. For this reason, the side surfaces 22 are located inside the area of the width of the top surface 21.

The lower end of the second side surface portion 221 is curled inward in the short direction Y to form a curled portion 223. As described below, the curled portion 223 is the portion of the set of fixture side surface portions 22 that is narrowest in the short direction Y. The lower end of the curled portion 223 is the opening end 26 described below, which is the end of the fixture side surface portion 22 in the vertical direction Z. Also, as described below, there is a gap between the end of the part of the curled portion 223 that is curled inward and the second side surface portion 221. Furthermore, as described below, the inside of the curled portion 223 has a space that becomes the capture groove 224 by being curled. Here, the second side surface portion 221 and the curled portion 223 are provided in a range where the end cover 40 is not arranged so as to face the cover 30 of the lamp 3 described below.

The open end 26 located at the bottom end of the fixture body 20 is the end of the open portion of the fixture body 20, and forms the tip of the fixture side portion 22. The open end 26 forms an attachment port for attaching and detaching the lamp 3 to the attachment portion 25 of the lamp attachment fixture 2. At the open end 26 of the fixture body 20, connecting portions 27 are formed at both ends in the longitudinal direction X. The lamp 3 is attached to the connecting portions 27. The lamp 3 is attached to and supported by the connecting portions 27.

In the first embodiment, the connecting portion 27 is formed integrally with the fixture end 23, and is formed by bending from the open end 26 toward the inward direction X2 in the longitudinal direction X. The screw hole 28 formed in the connecting portion 27 is a hole into which a connecting screw 48 (described later) attached to the lamp 3 is screwed. The lamp 3 is screwed and fixed to the lamp mounting fixture 2 by the connecting screw 48.

As shown in FIG. 5 and other figures, a plurality of correctors 29 are disposed on the mounting portion 25. In the first embodiment, the correctors 29 are fixed to the fixture top surface portion 21 using mounting screws 76. In the first embodiment, a plurality of correctors 29 are provided along the longitudinal direction X of the lamp mounting fixture 2.

The correction tool 29 is attached to a portion of the fixture body 20 other than the end portion in the longitudinal direction X. The correction tool 29 is attached to an area of the mounting section 25 where fixtures such as the hanging bolts 90 for mounting the lamp mounting fixture 2 to the ceiling or the like, which is the construction section 9, or terminal blocks (not shown) are not located.

The corrector 29 corrects the forming angle (θ2), which is the angle between the appliance top surface 21 and the appliance side surface 22 (first side surface 220) of the appliance main body 20, from the inside of the appliance main body 20. As shown in Figures 6, 7, and 8, the corrector 29 consists of a base 290 and a correcting portion 293 that rises from the end of the base 290 along a direction intersecting with the base 290. In the first embodiment, the corrector 29 is formed by bending a metal plate. The cross-sectional shape of the corrector 29 is approximately U-shaped. The corrector 29 is formed by selecting the material, composition, thickness dimension, shape, etc. so that the corrector 29 is more rigid than the appliance main body 20. The corrector 29 may be formed using a material other than metal as long as it can maintain the correction of the appliance main body 20. The corrector 29 is also formed by a processing method such as extrusion molding or three-dimensional modeling.

The base 290 has a through hole that is a screw insertion hole 291 through which a mounting screw 76 is inserted to attach the correction tool 29 to the instrument top surface 21. The correction tool 29 is fixed to the instrument body 20 by inserting the shaft of the mounting screw 76 through the screw insertion hole 291 provided in the base 290 and screwing it into the screw hole 210 provided in the instrument top surface 21.

Here, P1 shown in FIG. 3 etc. is the portion where the side surface portion 22 of the instrument body 20 is bent and raised, which is the boundary between the top surface portion 21 and the side surface portion 22, and is the base end portion of the side surface portion 22. W1 shown in FIG. 9 etc. is the distance between the outer (outer) portions of the two base ends P1 of one set of side surfaces 22. W2 shown in FIG. 9 etc. is the distance between the inner (inner) portions of the two base ends P1 of one set of side surfaces 22. W1 is the outer width dimension of the top surface portion 21 of the instrument in the short direction Y, and W2 is the inner width dimension of the top surface portion 21 of the instrument in the short direction Y.

P2 shown in FIG. 3 etc. is the bent portion of the second side portion 221. Furthermore, P3 shown in FIG. 3 etc. is the lower end portion of the device side portion 22. Here, P3 is the position of the opening end 26. And P4 shown in FIG. 3 etc. is the narrowest part of the side located at the innermost side in the short direction Y (second direction) in the curled portion 223.

Here, as shown in Figures 9 and 10, W3s is the distance dimension between the two narrowest side portions P4 in a pair of device side portions 22 before assembly when the corrector 29 is not attached to the device body 20. Here, the relationship between the distance dimension W1, the distance dimension W2, and the distance dimension W3s is W1>W2>W3s.

As shown in FIG. 11 and other figures, W3c is the distance between two P4s on a pair of side surfaces 22 of the device after assembly in which the corrector 29 is attached to the device body 20. Here, the relationship between the distance W1, the distance W2, and the distance W3c is W1>W2>W3c.

P5 shown in FIG. 3 and the like is the bent and raised portion of the straightening portion 293 that is the boundary between the base 290 and the straightening portion 293 of the straightening tool 29, and is the straightening base end of the straightening portion 293. W4 shown in FIG. 8 and FIG. 9 and the like is the distance dimension between the outer (outer surface) portions of the two straightening base ends P5 in one set of straightening portions 293. As shown in FIG. 9, the distance dimension W4 is the outer width dimension of the base 290 in the short direction Y. Also, W5 shown in FIG. 9 and the like is the distance dimension between the inner (inner surface) portions of the two straightening base ends P5 in one set of straightening portions 293. The distance dimension W5 is the inner width dimension of the base 290 in the short direction Y.

As shown in FIG. 8 and other figures, P6 is the end of the straightening section 293 opposite the straightening base end P5, and is the tip of the straightening section 293. W6 shown in FIG. 9 and FIG. 10 is the distance between the inner (inner) parts of the two tip parts P6 in a pair of straightening sections 293. W7 shown in FIG. 9 and other figures is the distance between the outer (outer) parts of the two tip parts P6 in a pair of straightening sections 293. Here, as shown in FIG. 8 and FIG. 9, the distance dimensions W4 and W7 have a relationship of W7>W4, and the distance dimensions W5 and W6 have a relationship of W6>W5.

As shown in FIG. 9, the fixture body 20 is formed so that the distance W3s between the two narrowest side portions P4 described above is equal to or smaller than the distance W8 between the two widest cover portions P7 of the lamp 3, described below, before the correction device 29 is attached to the fixture body 20.

9, the correction angle (θ1) between the base 290 of the correction tool 29 and the correction part 293 is greater than the molding angle (θ2) between the top surface 21 and the side surface 22 (first side surface 220) of the tool body 20 before the correction tool 29 is attached. The distance dimension (outer dimension) W4 between the outer surfaces of the correction base end P5, which is the end on the side of the base 290 of the correction part 293, is equal to or smaller than the distance dimension (inner dimension) W2 between the inner surfaces of the tool base end P1, which is the end on the side of the top surface 21 of the tool side surface 22 (first side surface 220). Here, the distance dimension W4 is the maximum distance dimension between the outer surfaces of the correction base end P5. The distance dimension W2 is the minimum distance dimension between the inner surfaces of the tool base end P1. In the lighting device 1 of embodiment 1, the corrector 29 is installed on the mounting part 25 side of the device body 20, so the distance dimension W4 is less than or equal to the distance dimension W2.

<Lighting fixture 3>
Next, the lamp 3 will be described mainly with reference to Figures 3 and 4. The lamp 3 is attached to the lamp mounting fixture 2 to constitute the lighting device 1. The lamp 3, which serves as a lighting fixture and light source unit, is formed in an elongated shape and is used by being attached to the lamp mounting fixture 2. In the first embodiment, the lamp 3 is attached to the connecting portion 27 of the lamp mounting fixture 2 by connecting screws 48, which will be described later, at both ends in the longitudinal direction X of the lamp mounting fixture 2. The lamp 3 of the first embodiment mainly has a cover 30, an end cover 40, and a light-emitting portion 60, as shown in Figures 2 and 3.

<Cover 30>
The cover 30, which is the outer shell, is a translucent cover that uses a translucent material that transmits at least visible light. The cover 30 has a cylindrical shape that houses and protects the mounting member 50, the light emitting unit 60, the control unit 80, etc., which will be described later, in the internal space. The cover 30 can be formed using glass or a resin material such as polycarbonate (PC) or acrylic (PMMA). In addition, the part of the cover 30 exposed to the outside from the mounting part 25 is the part from which the illumination light is emitted and is also the exterior design part. The cover 30 of the first embodiment can be manufactured, for example, by forming a cylindrical member by extrusion molding and cutting it to the required length according to the product specifications, etc.

In the lighting device 3 of the first embodiment, as shown in FIG. 3, the part of the cover 30 exposed to the outside from the mounting part 25 becomes an outer shell part that becomes an outer wall part covering the irradiation side of the light emitting part 60 and the surface of the base 51 in the mounting member 50. Here, for the cover outer periphery part 37 of the part exposed to the outside in the cover 30, the direction of the normal to the outer surface part is within the range from the direction along the optical axis of the light emitting element 61 to the direction perpendicular to the optical axis. For example, when the lighting device 3 is mounted on the lighting device mounting device 2 so that light is irradiated downward from the lighting device 1, the part exposed to the outside from the mounting part 25 of the cover 30 has an outer surface part facing downward, diagonally downward, or sideways (horizontally outward). In other words, the part exposed to the outside from the mounting part 25 of the cover 30 does not have an outer surface part facing upward or diagonally upward. In addition, the part of the cover 30 that is housed in the mounting part 25 and is not exposed to the outside covers the control part 80 and the side of the mounting surface part 52 in the base 51 where the control part 80 is arranged. The surface of the portion of the cover 30 that is housed in the mounting portion 25 and is not exposed to the outside faces the top surface 21 and the set of side surfaces 22 of the device body 20. The cover 30 may have light diffusion properties, wavelength discrimination properties, etc., depending on the product specifications. The portion of the cover 30 that is not exposed to the outside may be formed using a material that has reflectivity, light blocking properties, etc.

As shown in FIG. 3 and the like, the cylindrical cover 30 shown in the first embodiment covers the device housed inside, and is divided into a set of parallel parts 31, a first connecting part 32, and a second connecting part 33 depending on the position relative to the device housed inside. The set of parallel parts 31 forms a set of parallel surfaces at the same distance in the cover 30. In the cover 30, the outer surface part that is the outer surface part of the set of parallel parts 31 and the inner surface part that is the inner surface part are both planar. The set of outer surface parts and the set of inner surface parts are planes along the optical axis of the light-emitting element 61 housed in the cover 30. In the first embodiment, this plane is along the vertical direction Z when the lamp 3 is mounted on the lamp mounting device 2. Furthermore, this plane is also a plane along the opposing device side parts 22 and the opposing curl parts 223 when the lamp 3 is mounted on the lamp mounting device 2. This plane also coincides with the direction in which the lamp 3 is attached to the lamp mounting fixture 2 or removed from the lamp mounting fixture 2. Therefore, the parallel portion 31 of the cover 30 is not located outside the fixture side surface portion 22 in the short direction Y, but is located inside the fixture side surface portion 22 and faces the curled portion 223. The portion of the parallel portion 31 that is exposed when the lamp 3 is attached to the lamp mounting fixture 2 becomes the irradiating portion on the side of the lamp 3. In the lighting device 1 of embodiment 1, the distance between a pair of parallel portions 31 is the widest portion of the lamp 3.

Here, P7 is the widest part of the outer periphery 37 of the cover 30, which is the widest part in the short direction Y of the cover 30, and faces the narrowest part P4 of the side surface of the set of device side surfaces 22. P7 is part of the parallel part 31 of the outer periphery 37 of the cover.

When the lamp 3 is attached to the attachment portion 25 of the lamp mounting device 2, the cover outer periphery 37 of the cover 30 is the portion closest to the lamp mounting device 2. The widest part P7 of the cover in the parallel portion 31 of the cover outer periphery 37 and the narrowest part P4 of the side of the curled portion 223 are arranged opposite each other with a gap of (distance dimension W3c - distance dimension W8)/2. In addition, P3, which becomes the opening end 26, is located outside the narrowest part P4 of the side in the short direction Y.

Therefore, in the lighting device 1 of embodiment 1, the widest part P7 of the cover is located away from P3, where the opening end 26 is located, in the short direction Y. Therefore, the cover outer periphery 37 in the parallel portion 31 of the cover 30 having the widest part P7 and the curled portion 223 (particularly the opening end 26) having the narrowest side part P4 are in a positional relationship that does not overlap when viewed along the vertical direction Z.

The first connection portion 32 is a portion that connects the ends of the illuminating side of the pair of parallel portions 31, intersects with the optical axis of the light-emitting element 61, and is the main illuminating portion of the lamp 3. The first connection portion 32 irradiates the light from the light-emitting element 61 downward. The outer surface and inner surface of the first connection portion 32 are composed of one or more surfaces. As shown in FIG. 3 and the like, in the first embodiment, a case will be described in which the outer surface and inner surface of the first connection portion 32 in the cover 30 are composed of one curved surface. Here, when the outer surface and inner surface of the first connection portion 32 are composed of multiple surfaces, they can be composed of multiple curved surfaces with multiple different curvatures, multiple flat surfaces with multiple different angles, or a combination of these curved surfaces and flat surfaces. The second connection portion 33 is a portion that connects the ends of the pair of parallel portions 31 on the fixture side, and is a portion that is accommodated in the mounting portion 25 when the lamp 3 is mounted on the lamp mounting fixture 2. In the first embodiment, the outer surface and inner surface of the second connection portion 33 in the cover 30 are described as being composed of a single curved surface. Here, if the outer surface and inner surface of the second connection portion 33 are composed of multiple surfaces, they can be composed of multiple curved surfaces with multiple different curvatures, multiple flat surfaces with multiple different angles, or a combination of these curved surfaces and flat surfaces.

The wiring material 85 has various wires such as a power line 81, a ground line 82, and a control line 83 that are connected to the lighting fixture 3 from the outside. The wiring material 85 also includes terminals, wiring holders, and sockets that connect these wires. In FIG. 3, the power line 81, the ground line 82, and the control line 83 that are connected to the lighting fixture 3 are shown as wiring material 85. The wiring material 85 may be arranged in the wiring area within the mounting part 25 with each wire wrapped in an insulating material and bundled together with a coating or bundled with a cable tie. The wiring material 85 may also be arranged in the wiring area within the mounting part 25 with each wire separated.

In the first embodiment, the wiring material 85 is described as coming into contact with the cover 30. However, not only the wiring material 85, but also, for example, electric wires such as the feed wiring and dimming wire outside the lighting fixture 3 that are provided at the installation site, may come into contact with the covering by being placed within the wiring area. Although not shown, in the first embodiment, the cover 30 is an area that does not block the light emitted from the lighting fixture 3, and a plasticizer blocking portion may be provided in the part of the wiring material 85 that may come into contact with the covering.

Although not shown in the figures, the cover 30 may have a laminated structure made of multiple layers using different materials. The laminated structure can be formed by methods such as multi-color molding using different materials, film formation on the substrate surface by coating or spraying, and film lamination on the substrate surface. In this case, the inner layer, which is the layer close to the light-emitting section 60, is preferably formed using a material that is excellent in terms of impact resistance, heat resistance, or flame retardancy. In addition, the outer layer, which is the layer close to the irradiation space, is preferably formed using a material that is excellent in terms of water resistance, chemical resistance, antifouling properties, antistatic properties, or water absorption rate control.

For example, if the inner layer of the cover 30 is made of a material with excellent impact resistance, the cover 30 is less likely to be damaged even if it comes into contact with the light-emitting unit 60 when it is housed inside the cover 30. Also, for example, if the inner layer of the cover 30 is made of a material with excellent flame retardancy, it is possible to prevent the fire from spreading to the outside in the unlikely event of a fire caused by the light-emitting unit 60.

When the outer layer of the cover 30 is formed using a material that does not hydrolyze to the main chain, or when the outer layer is formed using a component with low water absorption, hydrolysis is unlikely to progress in the inner layer, and the function of protecting the light-emitting unit 60 is maintained for a long period of time. In addition, when the outer layer of the cover 30 is formed using a component with high water absorption, the amount of thermal expansion of the inner layer, which is affected by the operating heat of the light-emitting unit 60, can be balanced with the amount of water absorption and expansion of the outer layer, which is affected by water absorption, so that the inner layer and the outer layer are unlikely to peel off.

The cover 30 can be a heterogeneous material laminate structure, for example, in which a cylindrical member is formed using a material mainly composed of polycarbonate (PC) as the layer close to the light-emitting section 60, and a film mainly composed of acrylic (PMMA) is formed on the surface of the cylindrical member on the side of the irradiation space.

Furthermore, although not shown, a rib may be provided in each of the pair of parallel portions 31 in the longitudinal direction X for the purpose of stabilizing the shape of the cover 30 or improving its rigidity. In this case, the rib is formed in a position that faces the vicinity of the curled portion 223 in the fixture side portion 22 when the lamp 3 is attached to the lamp mounting fixture 2. Here, the rib is not formed on the outer surface of the end portion 36 so that the cover 30 can be fitted with the end cover 40 described later.

The cover 30 covers the light-emitting surface of the light-emitting element 61 arranged on the mounting member 50, and has an opening at the end 36 in the first direction, which is the longitudinal direction X along the longitudinal direction of the mounting member 50. In other words, the cover 30 is an elongated hollow body with at least one end 36 opening, and houses the board 62 on which the light-emitting element 61 is mounted inside. The cover end 35 is both end portions of the cover 30 in the longitudinal direction X of the cover 30. The cover end 35 of the cover 30 is provided with an end 36. The end 36 is a portion where the end cover 40 is fitted at the cover end 35, and is a portion covered by the end cover 40, which is an end cap. The end 36 is a free end that can move freely along the first direction, which is the longitudinal direction X, together with the end cover 40, as the cover 30 expands and contracts. Strictly speaking, the end 36 of the cover 30 and the end cover 40 expand and contract in directions other than the "longitudinal direction X", but in the lamp 3 according to the embodiment, the cover 30 has a structure (configuration) that allows expansion and contraction in the "longitudinal direction X". As shown in FIG. 3 and other figures, the cover outer periphery 37 of the cover 30 is the outer surface side of the outer shell portion that becomes the set of parallel portions 31, the first connecting portion 32, and the second connecting portion 33. The cover inner periphery 38 is the inner surface side of the outer shell portion that becomes the set of parallel portions 31, the first connecting portion 32, and the second connecting portion 33.

<Outline of End Cover 40>
As shown in Figures 1, 2, 12, etc., the end cover 40 is attached to both ends of the cover 30 in the longitudinal direction X. As shown in Figure 13, the end cover 40 is fitted or engaged with a sealing member 43 to give the cover 30 a sealed structure. Here, the mounting member 50 and the cover 30 attached to the end cover 40 have different amounts of expansion and contraction, particularly in the longitudinal direction X, in response to changes in the ambient temperature in which the lighting device 1 is used and in temperature when the lamp 3 is turned on and off. The end cover 40 is structured such that the ends of the cover 30 and the mounting member 50 in the longitudinal direction X can move relative to each other while maintaining the seal of the cover 30.

As shown in FIG. 13, the end cover 40 has a first end cover 41 that serves as an outer cover and a second end cover 42 that serves as an inner cover. The first end cover 41 has a first cover through hole 411, a first cover connection hole 412, a connection guide 413, a cover lower surface portion 414, a cover lower surface through hole 415, a cover electric wire holding portion 416, a cover end surface portion 417, a cover end surface through hole 418, and an end cover outer peripheral portion 419. Here, the cover lower surface through hole 415 is covered by a cover lid 49 as shown in FIG. 2. The second end cover 42 has a second cover main portion 420, an end cover insertion portion 421, a second cover engagement piece 422, a second cover engagement claw 423, and an end cover inner peripheral portion 425. An insertion wall 421a is formed along the edge portion that forms the end cover insertion portion 421. Here, the first end cover 41 and the second end cover 42 in the first embodiment are described as being formed using a resin material. However, this is not limited to this. They may be formed using metal materials, ceramic materials, and the like other than resin materials. Also, in the first embodiment, the first end cover 41 and the second end cover 42 are separate members that are fitted together or interlocked to be integrated, but they may be molded as a single integrated member in advance.

<Sealing device 43>
The seal 43 is an elastic member arranged at both ends of the cover 30 in the longitudinal direction X in a state where it is sandwiched between both ends of the cover 30 in the longitudinal direction X and the end cover 40. The seal 43, which is an elastic member, is attached to the end 36 of the cover 30 to close the opening of the end 36. The seal 43 is manufactured using a resin material and is a sealing member (gasket, packing, etc.) that is elastically deformable. Therefore, the seal 43 seals both ends of the cover 30 in the longitudinal direction X in a state where it is sandwiched between both ends of the cover 30 in the longitudinal direction X and the end cover 40. The seal 43 is formed using a resin material so as to be elastically deformable, and is in close contact with the cover 30 and the end cover 40.

The sealing device 43 has a sealing device main part 430, a sealing inner peripheral part 435, a sealing outer peripheral part 437, and a sealing connection part 436. The sealing device 43 has the sealing device main part 430, the sealing inner peripheral part 435, the sealing outer peripheral part 437, and the sealing connection part 436 formed integrally. The sealing device main part 430 is formed so as to block the inside of the sealing inner peripheral part 435. The sealing device main part 430 is sandwiched between the fixing part 56 of the fixing device 54 described later and the second cover main part 420 of the second end cover 42. The sealing device main part 430 is formed in a plate shape, and when the sealing device 43 and the end cover 40 are engaged, an electric wire insertion part 431 and a sealing device tubular part 433 are formed on the surface side facing the end cover 40. The sealing member main part 430 abuts against the second cover main part 420 of the second end cover 42 when the sealing member 43 and the end cover 40 are engaged. The wire insertion part 431 protrudes from the surface side facing the end cover 40 when the sealing member 43 and the end cover 40 are engaged, and forms a wire insertion hole 432 through which the power line 81, the ground line 82, and the control line 83 pass. Two sealing member cylindrical parts 433 are provided on either side of the wire insertion part 431, but the number of sealing member cylindrical parts 433 may be one or three or more as long as it is equal to or greater than the number of fixing parts 56 of the fixing member 54. The sealing member cylindrical part 433 protrudes from the surface side facing the end cover 40 when the sealing member 43 and the end cover 40 are engaged. When the sealing device 43 and the fixing device 54 are engaged, the boss portion 57 protruding from the fixing portion 56 of the fixing device 54 is inserted into the sealing device tubular portion 433. The sealing device tubular portion 433 is formed in a cylindrical shape. At the tip of the sealing device tubular portion 433, a screw insertion hole 434 is formed to screw in the fixing screw 75.

A sealing inner periphery 435 is formed on the periphery of the sealing member main part 430, which is formed in a plate shape. The sealing inner periphery 435 is the part that is sandwiched between the end cover inner periphery 425 of the second end cover 42 and the cover inner periphery 38 of the end 36 of the cover 30 when the sealing member 43, which is an elastic member, is engaged with the second end cover 42 and the cover 30.

The sealing outer periphery 437 of the sealing device 43 is formed in an annular shape and is disposed outside the cover inner periphery 38 so as to face the cover inner periphery 38. The sealing outer periphery 437 is a portion that is sandwiched between the outer wall portion 410a of the first end cover 41 and the cover outer periphery 37 of the cover 30 when the sealing device 43 is engaged with the first end cover 41 and the cover 30.

The sealing connection part 436 of the sealing device 43 is located between the sealing inner peripheral part 435 and the sealing outer peripheral part 437 of the sealing device main part 430. The sealing connection part 436 is the part that is sandwiched between the first cover main part 410 of the first end cover 41 and the cover end part 35 of the cover 30 when the sealing device 43 is engaged with the first end cover 41 and the cover 30.

The connecting member 44 is a connector, and is provided at both ends of the lamp 3 in the longitudinal direction X, and is a mounting bracket for mounting the lamp 3 to the lamp mounting device 2. The connecting member 44 is attached and fixed to the fixing device 54 using two fixing screws 75 with the surface of the center side (X2 side) in the longitudinal direction X (first direction) of the fixing part 46 abutting the end face of the boss part 57. The connecting member 44 is not directly fixed to the end cover 40 using screws or the like. The connecting member 44 is positioned and indirectly fixed via a sealing device 43 that is in close contact with the boss part 57 of the fixing device 54. That is, the connecting member 44 is arranged outside the end cover 40 in the first direction, which is the longitudinal direction X of the lamp 3, and a part of it is fixed to the mounting member 50 that penetrates the end cover 40, and the other part is fixed to the lamp mounting device 2. In the first embodiment, the connecting member 44 is formed by bending a metal plate material. However, the connecting member 44 is not limited to being formed by bending a metal plate material, and may be formed using other materials such as resin or ceramic, or may be formed by other methods such as extrusion molding or additive manufacturing. The connecting member 44 has a connecting portion 45, a fixing portion 46, and an engaging portion 47.

The connecting portion 45 is a plate-like member that extends from the lower end (Z2 side) of the fixing portion 46 to the end side (X1 side) of the lamp 3. That is, the connecting portion 45 is a plate-like member that protrudes from the lower edge of the fixing portion 46. When the connecting portion 45 is engaged with the end cover 40, it protrudes on the side opposite the end cover 40. In other words, the connecting portion 45 protrudes on the side opposite the protruding direction of the engaging portion 47. When the lamp 3 is attached to the lamp mounting fixture 2, the upper surface of the connecting portion 45 other than the step portion 450 abuts against the connecting portion 27 of the lamp mounting fixture 2.

The connecting portion 45 has a step portion 450 with different surface heights, and the step portion 450 has a connecting screw insertion portion 451 into which the connecting screw 48 is inserted. The step portion 450 is a portion recessed downward (toward the Z2 side) in the central region of the short direction Y of the connecting portion 45. A retaining washer 480 that fixes the connecting screw 48 that has passed through the connecting screw insertion portion 451 is disposed in the step portion 450 of the connecting portion 45. This retaining washer 480 is fitted to the connecting screw 48 in advance so that it does not come off from the connecting screw 48. The height (depth, step) dimension of the step portion 450 is the same dimension as the thickness dimension of the retaining washer 480. When the lamp 3 is attached to the lamp mounting fixture 2, the upper (Z1 side) surface of the retaining washer 480 abuts against the connecting portion 27 of the lamp mounting fixture 2, and the lower (Z2 side) surface of the retaining washer 480 abuts against the step portion 450 of the connecting member 44. The shape and area of the step portion 450 are determined taking into consideration the shape and dimensions of the retaining washer 480. The connecting screw insertion portion 451 is formed in a slit shape from the end side (X1 side) in the longitudinal direction X (first direction) at approximately the center of the step portion 450 in the short direction Y. The connecting screw insertion portion 451 is formed with a width dimension larger than the screw body portion 481 of the connecting screw 48, and the screw body portion 481 of the connecting screw 48 is inserted into the connecting screw insertion portion 451. The shape of the connecting screw insertion portion 451 is not limited to a slit shape, and may be a through hole having a circular or polygonal cross section, including an elliptical cross section.

The fixing portion 46 is a portion of the connecting portion 45 that extends upward from the end portion on the central side (X2 side) in the longitudinal direction X (first direction). The fixing portion 46 is a plate-shaped member. The fixing portion 46 clamps the end cover 40 and the sealing device 43 together with the fixing device 54 of the mounting member 50. The fixing portion 46 has a fixing screw insertion hole 460 for screwing the fixing screw 75. The fixing screw insertion hole 460 is a through hole through which the fixing screw 75 that is screwed into the screw hole 58 of the boss portion 57 is inserted. The fixing portion 46 is attached to the boss portion 57 by the fixing screw 75 inserted into the fixing screw insertion hole 460.

The connecting member 44 has a slit-shaped wire insertion hole 470 through which wires such as the power line 81, the ground line 82, and the control line 83 pass. The wire insertion hole 470 has an upper slit 4710 and an end slit 4711. The wire insertion hole 470 formed in the fixing portion 46 is referred to as the end slit 4711. The end slit 4711 is formed in the up-down direction (Z-axis direction) of the connecting member 44. The end slit 4711 is connected to an upper slit 4710 (described later) formed in the engaging portion 47.

The fixed portion 46 may have an engagement piece insertion hole 461. The engagement piece insertion hole 461 is a through hole provided in the fixed portion 46 in accordance with the cross-sectional shape of the second cover engagement piece 422 and the second cover engagement claw 423 of the second end cover 42. The engagement piece insertion hole 461 is formed so that the second cover engagement piece 422 and the second cover engagement claw 423 of the second end cover 42, which move in the longitudinal direction X (first direction) as the cover 30 extends, do not interfere with the fixed portion 46 of the connecting member 44. The engagement piece insertion hole 461 is not necessary when the amount of extension of the cover 30, i.e., the amount of movement of the second cover engagement piece 422 and the second cover engagement claw 423, is small, or when the end cover 40 is formed integrally, and is not an essential component of the lamp 3.

The engagement portion 47 is a portion of the fixed portion 46 that extends from the upper end (Z1 side) toward the center (X2 side) in the longitudinal direction X (first direction). In other words, the engagement portion 47 is a plate-shaped member that protrudes from the upper edge of the fixed portion 46. When engaged with the end cover 40, the engagement portion 47 protrudes toward the end cover 40, and is disposed on the upper side (Z1 side) of the lamp 3.

As described above, the connecting member 44 has a slit-shaped wire insertion hole 470 through which wires such as the power line 81, the ground line 82, and the control line 83 pass. The wire insertion hole 470 formed in the engagement portion 47 is called the 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 is a slit formed in the engagement portion 47 of the connecting member 44 to make the end 36 of the cover 30 and the end cover 40 free ends whose movement in the longitudinal direction X (first direction) is not restricted. The cover wire holding portion 416 inserted from the insertion hole 472 described later engages with the upper slit 4710 in a state in which movement in the lateral direction Y and the vertical direction Z is restricted. Here, the cover electric wire holding portion 416 arranged in the insertion hole 472 is not restricted in movement 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 relative to the end cover 40 is determined, so that it is easy to align the fixing screw 75 when fixing the connecting member 44 to the boss portion 57 using the fixing 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 generally become hard and difficult to bend. However, since the connecting member 44 has an end slit 4711 formed to be connected to the upper slit 4710, wiring is easy even if the power line 81 and the like are bundled and difficult to bend.

The engaging portion 47 has an insertion hole 472 into which the cover electric wire holding portion 416 described later is inserted. The insertion hole 472 is formed continuous with the upper slit 4710. The insertion hole 472 is a through hole formed in the fixing portion 46, and is formed to be connected to the center side (X2 side) of the upper slit 4710 in the longitudinal direction X (first direction). The insertion hole 472 is formed with a shape and dimensions that allow the cover electric wire holding portion 416 to be inserted. The cover electric wire holding portion 416 inserted from the insertion hole 472 moves along the longitudinal direction X while engaged with the upper slit 4710 in response to the extension of the cover 30. Therefore, the cover electric wire holding portion 416 does not interfere with the extension and contraction of the cover 30, and the movement of the end cover 40 and the sealing device 43 accompanying the extension and contraction of the cover 30.

<Mounting member 50>
As shown in Fig. 3 and Fig. 9, the mounting member 50 is a member for fixing the light emitting unit 60, the control unit 80, etc., in the space within the cover 30. The mounting member 50 is also a member for fixing the mounting member 50 to the end cover 40 and the connecting member 44 attached to both ends of the cover 30. The mounting member 50 has a base 51 and a fixing device 54. The mounting member 50 is housed in the cover 30. Then, as shown in Fig. 9, the mounting member 50 is fixed to the end cover 40 and the connecting member 44 by a fixing screw 75. Therefore, the mounting member 50 is not directly fixed to the cover 30, but is connected to the cover 30 via the end cover 40 that is fitted or fitted to the cover end portions 35 on both sides in the longitudinal direction X of the cover 30.

The base 51 is the main part of the mounting member 50, and the light emitting unit 60 and the control unit 80 are attached to it. In the first embodiment, the base 51 is formed by bending a metal plate material. However, the base 51 is not limited to being formed by bending a metal plate material, and may be formed using materials other than metal, such as resin and ceramic, or may be formed by other methods, such as extrusion molding and additive manufacturing. Although not shown, the base 51 may be surface-treated or a functional member may be laid on the base 51 to improve the heat dissipation efficiency (thermal emissivity) or the light utilization efficiency (reflectivity). The base 51 has a mounting surface portion 52 and a side portion 53. The mounting surface portion 52 of the base 51 is formed in a long flat plate shape, and the light emitting unit 60 is attached to the front surface, which is the surface on the irradiation side. In addition, the control unit 80, such as a power supply unit, is attached to the back surface, which is the surface on the device side.

As shown in FIG. 9, the mounting surface portion 52 of the base 51 has a screw hole 520 formed therein. The screw hole 520 is formed at both ends of the mounting surface portion 52 in the longitudinal direction X. Fixing screws 75 for fixing the mounting member 50 to the end cover 40 and the connecting member 44 are inserted into the screw hole 520. The mounting surface portion 52 has a notch portion 521 formed therein, through which the power supply line 84 and the like can pass. The notch portion 521 is formed at the edge of the mounting surface portion 52 at both ends of the mounting surface portion 52 in the longitudinal direction X. Here, instead of the notch portion 521 being formed in the mounting surface portion 52 at the other end of the lamp 3, a mounting hole, which is a through hole, is formed.

The side parts 53 of the base 51 are bent and raised from both ends of the mounting surface part 52 in the short direction Y toward the irradiation side. The side parts 53 are erected from the edges of the mounting surface part 52 along the long direction X of the mounting surface part 52, thereby improving the rigidity of the base 51. In the first embodiment, the side parts 53 are erected only on the side of the lamp mounting device 2 on which the control part 80 and the like are arranged. However, the side parts 53 may be erected only on the irradiation side on which the light emitting part 60 is arranged, or may be erected on both the irradiation side and the side of the lamp mounting device 2. In the first embodiment, the side parts 53 are erected on both ends of the mounting surface part 52 in the short direction Y, but they may be installed so as to rise at a position other than both ends, such as the center part in the short direction Y of the mounting surface part 52.

The fixing device 54 is disposed at both ends of the base 51 in the longitudinal direction X, and is a member that fixes the mounting member 50 to the end cover 40 and the connecting member 44 attached to both ends of the cover 30. The fixing device 54 penetrates the end cover 40 and the connecting member 44 is fixed to it. Here, in the first embodiment, the fixing device 54 is configured as a separate member from the base 51, but the configuration of the fixing device 54 is not limited to this configuration. For example, the base 51 and the fixing device 54 may be integrally formed by bending both ends of the base 51, so that the base 51 has a part that has the same function as the fixing device 54. The fixing device 54 may be attached to the base 51 using a fixing member such as a mounting screw (not shown).

The fixture 54 has an attachment portion 55 and a fixing portion 56, and is manufactured by bending sheet metal. Here, the fixture 54 is a metal fitting, but is not limited to metal fittings, and may be formed using other materials, such as resin or ceramic, or may be formed by other methods, such as extrusion molding or additive manufacturing.

The mounting portion 55 of the fixture 54 is a portion that mounts the fixture 54 to the base 51, and is fixed to both ends of the base 51 using fixing screws 75. The mounting portion 55 may be structurally integrated with the base 51 by, for example, crimping, welding, fitting, or engagement.

The fixing portion 56 of the fixing device 54, together with the fixing portion 46 of the connecting member 44, clamps the end cover 40 and the sealing device 43. In other words, when the cover 30, the sealing device 43, the end cover 40, and the connecting member 44 are combined, the sealing device 43 is disposed between the fixing portion 56 and the fixing portion 46 of the connecting member 44. The fixing portion 56 is provided with a boss portion 57.

The boss portion 57 is attached to the fixing portion 56 by, for example, caulking, welding, or fitting. A screw hole 58 into which a fixing screw 75 is screwed is formed in the boss portion 57. A screw groove is formed on the inner periphery of the screw hole 58. Then, from the outside of the connecting member 44, a fixing screw insertion hole 460 of the connecting member 44, an end cover insertion portion 421 of the second end cover 42, a first cover through hole 411 of the first end cover 41, and a screw insertion hole 434 of the sealing device 43 are inserted. Then, the fixing screw 75 is screwed into the screw hole 58 of the boss portion 57, and the connecting member 44 is fixed to the fixing device 54 of the mounting member 50. That is, the connecting member 44 is fixed to the boss portion 57 of the fixing device 54.

<Light Emitting Unit 60>
As shown in FIG. 3 and the like, the light-emitting unit 60 has a light-emitting element 61, a substrate 62, and the like. The light-emitting element 61 emits light when power is supplied. In the first embodiment, a light-emitting diode (hereinafter referred to as LED) element is used as the light-emitting element 61, and the light-emitting element 61 is mounted on the mounting surface of the substrate 62 in a row or a staggered manner along the longitudinal direction X. The light-emitting element 61 of the first embodiment is a pseudo-white LED element that is a surface-mounted component packaged by disposing a phosphor that converts the wavelength of blue light into yellow light on an LED chip that emits blue light with a wavelength of 440 to 480 [nm]. Here, the light emitted by the light-emitting element 61 has a maximum luminous flux value and spreads symmetrically by an irradiation angle α with respect to an 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 120 degrees. The light emitting element 61 may be a solid state laser, a semiconductor laser, an organic electroluminescence (EL), an inorganic EL, etc. The substrate 62 may be 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-based substrate, etc.

The control unit 80 is a power supply device, and converts the power supplied from the outside into power that lights the light-emitting element 61 and supplies it to the light-emitting element 61. In the lighting device 1 of the first embodiment, the control unit 80 is attached to the back surface of the mounting surface portion 52 of the base 51 using a fixing member such as a screw (not shown), and is housed in the cylindrical cover 30 together with the light-emitting element 61, as described above. However, the control unit 80 may be configured to be attached to the lighting device mounting device 2 instead of the lighting device 3. In this case, the electric wire becomes a power supply line that functions as a supply path for power supplied from the control unit 80 to the light-emitting element 61. One end of the electric wires such as the power line 81, the ground line 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 wires is connected to a terminal block (not shown) attached to the lighting device mounting device 2.

<Action and Effects>
The straightening portion 293 of the straightening tool 29 extends to a position where it can straighten the tip portion of the instrument side surface portion 22 of the instrument body 20. Specifically, the straightening portion 293 extends to near the upper end of the curled portion 223. The outer surface of the tip portion P6 of the straightening portion 293 comes into contact with the inner surface of the instrument side surface portion 22 of the instrument body 20 in an assembled state in which the straightening tool 29 is attached to the instrument body 20.

When the base 290 is attached to the instrument top surface 21 of the instrument body 20, the straightening tool 29 straightens the instrument side surface 22 so that the molding angle (θ2), which is the angle between the instrument top surface 21 and the instrument side surface 22 (first side surface 220), becomes the straightening angle (θ1), which is the angle between the base 290 and the straightening part 293. Here, straightening so that the molding angle (θ2) becomes the straightening angle (θ1) includes the molding angle (θ2) being the same as the straightening angle (θ1) and the molding angle (θ2) being close to the straightening angle (θ1).

The corrector 29 is formed by selecting a material, composition, thickness dimension, shape, etc. that gives it greater rigidity than the instrument body 20. Therefore, in the assembled state in which the corrector 29 is attached to the instrument body 20, the tip P6 of the corrector 293 can displace the inner surface of the instrument side portion 22 of the instrument body 20 toward the outside in the short direction Y (second direction).

For example, as shown in FIG. 14, before the fixture end 23 and the correcting tool 29 are attached, the fixture body 20 before assembly has the distance dimension W3s between the two narrowest side portions P4 narrower than the distance dimension W8 between the two widest cover portions P7 of the lamp 3, as described above. Then, as shown in FIG. 16, when the fixture end 23 is attached, the end of the fixture body 20 widens, but the other portions do not widen. On the other hand, as shown in FIG. 11 and FIG. 16, by attaching the correcting tool 29 to the fixture body 20, the distance dimension W3c between the two narrowest side portions P4 described above is corrected by the correcting part 293 so that it is equal to or larger than the distance dimension W8 between the two widest cover portions P7 of the lamp 3. Therefore, in the first embodiment, the fixture body 20 is provided with the correcting tool 29, so that the parts other than the parts widened by the fixture end 23 are widened to the distance dimension W3c, and the opening dimensions can be precisely controlled throughout the entire fixture body 20.

When the fixture side surface portion 22 of the fixture body portion 20 is corrected by the correction portion 293 so that the distance dimension W3c is greater than the distance dimension W8 between the two widest cover portions P7 of the lamp 3, the cover 30 is not damaged when the lamp 3 is attached to the lamp mounting fixture 2. In addition, by separating the narrowest side portion P4 from the cover 30, noise caused by friction, rubbing, etc. is prevented from being generated.

By arranging the correction tool 29 close to the hanging bolt 90, or by arranging the correction tool 29 on both sides of the hanging bolt 90, the correction tool 29 functions as a deformation suppression tool for the lamp mounting device 2 that is attached to the construction part 9, such as the ceiling, during construction.

The fixture body 20 is corrected by the corrector 29, which is formed by selecting a material, composition, thickness dimension, shape, etc. that is more rigid than the fixture body 20, so the thickness dimension can be reduced and the shape can be simplified. This provides the effect of reducing the weight and cost of the lamp mounting fixture 2.

<Modification 1>
Fig. 17 is a cross-sectional view illustrating a vertical cross section of the lighting device 1 orthogonal to the longitudinal direction X of the lighting device 1 according to the first modification of the embodiment 1. Fig. 18 is a perspective view of a corrector 29a according to the first modification of the embodiment 1.

The base 290a of the corrector 29a is formed with a hanging bolt insertion hole 292 through which the hanging bolt 90 can be inserted. The corrector 29a is formed by selecting the material, composition, thickness dimension, shape, etc. so that it has a higher rigidity than the fixture body 20. For this reason, the corrector 29a may be used as a member through which the hanging bolt 90 is inserted and which receives the nut 91 or washer 92 that is tightened to the hanging bolt 90. In this case, the corrector 29a is attached to an area of the mounting section 25 where a fixing device such as the hanging bolt 90 for mounting the lamp mounting fixture 2 to the ceiling, which is the construction section 9, is arranged. Since the corrector 29a is formed to have a higher rigidity than the fixture body 20, it is less susceptible to the stress caused by tightening the nut 91, and deformation of the lamp mounting fixture 2 including the fixture body 20 can be prevented.

In other words, the correction device 29a functions as a deformation prevention device for the lamp mounting device 2 that is attached to the construction part 9, such as the ceiling, during construction.

<Modification 2>
Although not shown in the drawings, a movement restricting portion may be provided on the instrument body portion 20 in order to restrict the movement of the corrector 29 along the longitudinal direction X or the up-down direction Z of the instrument body portion 20. The movement restricting portion is provided on at least one of the instrument top surface portion 21 and the instrument side surface portion 22. The movement restricting portion may be formed by cutting out a part of the instrument body portion 20, or a movement restricting member that is a separate member may be attached to the instrument top surface portion 21 or the instrument side surface portion 22.

<Modification 3>
Although not shown in the drawings, the correction tool 29 may be fixed to the tool body 20 using a main fixing means other than the mounting screw 76. For example, a method using rivet fastening, cut-and-raised fastening, cut-and-raised engagement, or the like can be adopted.

<Modification 4>
Although not shown in the drawings, the corrector 29 may be attached to the instrument body 20 by fixing the correcting portion 293 to the instrument side surface portion 22 using the fixing means described above. Alternatively, the main fixing means may be the engagement between the curl portion 223 and the correcting portion 293. In this case, it is possible to adopt a method of combining an auxiliary means for joining the corrector 29 to the instrument body 20 by an adhesive member.

<Modification 5>
Although not shown in the drawings, the correcting tool 29 may be configured such that the correcting portion 293 and the instrument side portion 22 are spaced apart when the base portion 290 is attached to the instrument top surface portion 21. The instrument side portion 22 may be corrected using a fixing means such as a screw so that the spaced-apart correcting portion 293 and the instrument side portion 22 are in contact with each other at least in part.

<Modification 6>
Although not shown, the corrector 29 may be fitted with functional parts such as a terminal block to which an external power supply line or wiring material 85 is connected, a wiring holder to which a feed wiring is connected, and a connector.

Embodiment 2.
Fig. 19 is a cross-sectional view showing a vertical cross section of the lighting device 1 perpendicular to the longitudinal direction X of the lighting device 1 according to embodiment 2. Fig. 20 is a perspective view of a corrector 29e according to embodiment 2. Here, in the devices shown in Fig. 19 etc. described in embodiment 2, the devices etc. having the same reference numerals as those in Fig. 3 etc. have the same functions as those described in embodiment 1 etc.

As shown in FIG. 19, the corrector 29e according to the second embodiment has a corrective connection portion 294 that connects the base portion 290e and the corrective portion 293e. The corrective connection portion 294 is a flat surface. The corrector 29e is made up of five flat surfaces, and has a generally U-shaped cross section.

The corrective connection part 294 rises from the inside of the end of the base part 290 in the first embodiment along a direction intersecting with the base part 290e, and extends toward a position between the base end and the tip end of the instrument side part 22. The corrective part 293e extends from the end of the corrective connection part 294 opposite the base part 290e toward the tip end of the instrument side part 22.

In the assembled state in which the correction tool 29e is attached to the device body 20, the area surrounded by the correction connection part 294, the device top surface part 21, and the device side surface part 22 is connected to the mounting part 25 along the longitudinal direction X. This area can be used, for example, as an electric wire holding part 250 that holds electric wires such as feed wiring that are pulled in from an adjacent lighting device, etc.

In addition, in the pre-assembly state without the straightener 29e attached, the distance between the ends of the base 290e in the short direction Y (second direction) is smaller than the distance W3 between the two narrowest side portions P4 of the curled portion 223 that are located on the innermost side in the short direction Y. This makes it easier to attach the straightener 29e to the fixture body 20, improving the ease of assembly of the lamp mounting fixture 2.

<Modification 1>
Fig. 21 is a cross-sectional view illustrating a vertical cross section of the lighting device 1 according to the first modification of the second embodiment, which is perpendicular to the longitudinal direction X of the lighting device 1. Fig. 22 is a perspective view of a corrector 29f according to the first modification of the second embodiment.

As shown in FIG. 22, the corrector 29f according to the first modification of the second embodiment has a corrective connection part 294f that connects the base part 290f and the corrective part 293f. The corrective connection part 294f is a curved surface, and the corrector 29f is composed of three flat surfaces and two curved surfaces, and has a generally U-shaped cross section.

The corrective connection portion 294f rises from inside the end of the base portion 290 in the first embodiment along a direction intersecting with the base portion 290f. Then, the inclination angle with respect to the base portion 290f gradually increases as the corrective connection portion 294f extends toward a position between the base portion and the tip portion of the instrument side portion 22. The corrective portion 293f extends from the end of the corrective connection portion 294f opposite the base portion 290f toward the tip portion of the instrument side portion 22.

The straightening connection part 294f connects the base part 290f and the straightening part 293f with a continuous curved surface, and the stress generated when straightening the fixture side part 22 is not concentrated in a specific part such as the bent part 222, but is distributed throughout the straightening tool 29f. Therefore, the straightening tool 29f can continue to straighten the fixture side part 22 for a long period of time, and the straightened shape of the lamp mounting fixture 2 is maintained for a long period of time.

In the assembled state in which the correction tool 29f is attached to the device body 20, the area surrounded by the correction connection part 294f, the device top surface part 21, and the device side surface part 22 is connected to the mounting part 25 along the longitudinal direction X. This area can be used, for example, as the electric wire holding part 250f that holds electric wires such as feed wiring that are pulled in from an adjacent lighting device, etc.

In addition, in the pre-assembly state without the straightener 29f attached, the distance between the ends of the straightener 29f in the short direction Y (second direction) is smaller than the distance W3 between the two narrowest side portions P4 of the curled portion 223 that are located on the innermost side in the short direction Y. This makes it easier to attach the straightener 29f to the instrument body 20, improving the ease of assembly of the lamp mounting instrument 2.

<Modification 2>
Fig. 23 is a cross-sectional view illustrating a vertical cross section of the lighting device 1 orthogonal to the longitudinal direction X of the lighting device 1 according to the second modification of the second embodiment. Fig. 24 is a perspective view of a corrector 29g according to the second modification of the second embodiment.

As shown in FIG. 24, the corrector 29g according to the second modification of the second embodiment does not have a corrective portion 293 that runs along (faces) the side surface of the device 22. The corrective connection portion 294g rises from inside the end of the base 290d in the first embodiment along a direction that intersects with the base 290d, and extends toward the tip of the side surface of the device 22. The tip of the corrective connection portion 294g is slightly bent. The corrective connection portion 294g is flat except for the tip, and the cross-sectional shape of the corrector 29g is roughly U-shaped.

The instrument side portion 22 is corrected by the tip of the corrective connection portion 294g. In other words, the tip of the corrective connection portion 294g has the function of correcting the instrument side portion 22.

In the assembled state in which the correction tool 29g is attached to the device body 20, the area surrounded by the correction connection part 294g, the device top surface part 21, and the device side surface part 22 is connected to the mounting part 25 along the longitudinal direction X. This area can be used, for example, as a wire holding part 250g that holds wires such as feed wiring that are pulled in from an adjacent lighting device, etc.

In addition, when the lamp 3 is attached to the lamp mounting fixture 2, the cover 30 of the lamp 3 comes into contact with or is close to the inner surface of the corrective connection portion 294g. Therefore, the lamp 3 is guided to the correct position for mounting by the corrective connection portion 294g. With this configuration, the lamp 3 guided by the correction device 29g is mounted in the correct position and posture of the lamp mounting fixture 2 corrected by the correction device 29g. And, it is possible to maintain balance in the gap between the lamp mounting fixture 2 (curl portion 223) and the lamp 3 (cover 30).

Embodiment 3.
FIG. 25 is a cross-sectional view showing a vertical section of the lighting device 1 perpendicular to the longitudinal direction X of the lighting device 1 according to the third embodiment. FIG. 26 is an exploded perspective view of the lamp mounting device 2h according to the third embodiment. FIG. 27 is a view showing a state before the corrector 29h is attached to the lamp mounting device 2h according to the third embodiment. FIG. 28 is a view showing a state in which the corrector 29h is being attached to the lamp mounting device 2h according to the third embodiment. FIG. 29 is a view showing a state after the corrector 29h is attached to the lamp mounting device 2h according to the third embodiment. Here, in the devices shown in FIG. 25 and the like described in the third embodiment, the devices and the like having the same reference numerals as those in FIG. 3 and the like have the same functions as those described in the first embodiment and the like.

The lamp mounting device 2h according to the third embodiment includes a correction tool 29h that is attached to the outside of the device body 20h. In the third embodiment, the correction tool 29h is fixed to the device top surface 21h using a mounting screw 76. In the third embodiment, a plurality of correction tools 29h are provided along the longitudinal direction X of the lamp mounting device 2h.

The correction tool 29h is attached to a portion of the fixture body 20h other than the end portion in the longitudinal direction X. The correction tool 29h is attached to an outer area of the fixture body 20h where there are no fixing devices such as hanging bolts 90 for attaching the lamp mounting fixture 2h to the ceiling or the like, which is the construction part 9, or power line inlet holes for pulling in an external power line (not shown).

The straightening tool 29h corrects the molding angle (θ2), which is the angle between the appliance top surface 21h and the appliance side surface 22 (first side surface 220) of the appliance main body 20h, from the outside of the appliance main body 20h.

The base 290h has a through hole, which is a screw insertion hole 291 through which a mounting screw 76 for mounting the correction tool 29h to the instrument top surface 21h is inserted. The correction tool 29h is fixed to the instrument body 20h by inserting the mounting screw 76 (the shaft portion) through the screw insertion hole 291 provided in the base 290h and screwing it into the screw hole 210h provided in the instrument top surface 21h.

Here, W9s is the distance between the outsides of the two P2s in a pair of device side sections 22h before assembly when the corrector 29h is not attached to the device body section 20h. The distance dimension W1 and the distance dimension W9s have a relationship of W9s ≧ W1.

W9c is the distance between the outsides of the two P4s on the pair of side surfaces 22h of the device after assembly in which the corrector 29h is attached to the device body 20h. The distance W9s and the distance W9c have a relationship of W9s > W9c.

Furthermore, in the corrector 29h, the distance dimensions W4 and W7 have a relationship of W7≦W4, and the distance dimensions W5 and W6 have a relationship of W6≦W5.

The fixture body 20h is formed so that the distance W3s between the two narrowest side portions P4 is equal to or smaller than the distance W8 between the two widest cover portions P7 of the lamp 3 before the straightener 29h is attached to the fixture body 20h.

27, the correction angle (θ1) between the base 290h of the correction tool 29h and the correction part 293h is smaller than the molding angle (θ2) between the instrument top surface part 21h and the instrument side surface part 22h (first side surface part 220h) before the correction tool 29h is attached. The distance dimension (inner dimension) W5 between the inner surfaces of the correction base end part P5, which is the end part on the side of the base 290h of the correction part 293h, is equal to or greater than the distance dimension (inner dimension) W1 between the outer surfaces of the instrument base end part P1, which is the end part on the side of the instrument top surface part 21h of the instrument side surface part 22h (first side surface part 220h). Here, the distance dimension W5 is the minimum distance dimension between the inner surfaces of the correction base end part P5. Also, the distance dimension W1 is the maximum distance dimension between the outer surfaces of the instrument base end part P1. In the lighting device 1 of embodiment 3, the correction tool 29h is installed on the outer surface side of the fixture body 20h, so the distance dimension W1 is equal to or less than the distance dimension W5.

The straightening portion 293h of the straightening tool 29h extends to a position where it can straighten the tip of the instrument side portion 22h of the instrument body portion 20h. Specifically, the straightening portion 293h extends to the vicinity of the lower end of the first side portion 220h, i.e., to the vicinity of the upper end of the curled portion 223. The inner surface of the tip portion P6 of the straightening portion 293h contacts the outer surface of the instrument side portion 22h of the instrument body portion 20h in the assembled state where the straightening tool 29h is attached to the instrument body portion 20h.

When the base 290h is attached to the appliance top surface 21h of the appliance main body 20h, the straightening tool 29h straightens the appliance side surface 22h so that the molding angle (θ2), which is the angle between the appliance top surface 21h and the appliance side surface 22h (first side surface 220h), becomes the straightening angle (θ1), which is the angle between the base 290h and the straightening part 293h. Here, straightening so that the molding angle (θ2) becomes the straightening angle (θ1) includes the molding angle (θ2) being the same as the straightening angle (θ1) and the molding angle (θ2) being close to the straightening angle (θ1).

The corrector 29h is formed by selecting a material, composition, thickness dimension, shape, etc. so that it has a higher rigidity than the instrument body 20h. Therefore, in the assembled state in which the corrector 29h is attached to the instrument body 20h, the tip P6 of the corrector 293h can displace and deform the outer surface of the instrument side portion 22h of the instrument body 20h toward the inside in the short direction Y (second direction).

In this way, by attaching the straightening tool 29h to the main body 20h, the side surface 22h of the fixture is straightened by the straightening part 293h so that the distance dimension W3c between the two narrowest side surface parts P4 described above is equal to or greater than the distance dimension W8 between the two widest cover parts P7 of the lamp 3.

The fixture side surface portion 22h of the fixture body portion 20h is corrected by the correction portion 293h so that the distance dimension W3c is greater than the distance dimension W8 between the two widest cover portions P7 of the lamp 3, which prevents the cover 30 from being damaged when the lamp 3 is attached to the lamp mounting fixture 2h. In addition, the narrowest side portion P4 is spaced apart from the cover 30, which prevents abnormal noise caused by friction, rubbing, etc. from being generated.

The corrector 29h functions as a deformation suppression device for the lamp mounting device 2h that is attached to the construction part 9, such as the ceiling, during construction by placing the corrector 29h close to the hanging bolt 90 or by placing multiple corrector 29h with the hanging bolt 90 between them.

<Modification 1>
FIG. 30 is a cross-sectional view that typically shows a vertical cross section of the illumination device 1 according to the first modification of the third embodiment, perpendicular to the longitudinal direction X of the illumination device 1. As shown in FIG.

The base 290i of the correction tool 29i is formed with a hanging bolt insertion hole 292 through which the hanging bolt 90 can be inserted. The material, composition, thickness, shape, etc. of the correction tool 29i are selected and formed so that the rigidity is higher than that of the fixture body 20i. For this reason, the correction tool 29i may be used as a member through which the hanging bolt 90 is inserted and which receives the nut 91 or washer 92 that is tightened to the hanging bolt 90. In this case, the correction tool 29i is attached to the outer area of the fixture body 20i where the fixing device such as the hanging bolt 90 for attaching the lamp mounting fixture 2i to the ceiling, which is the construction part 9, is arranged. Since the correction tool 29i is formed to be higher in rigidity than the fixture body 20i, it is less susceptible to the stress caused by tightening the nut 91, and deformation of the lamp mounting fixture 2i including the fixture body 20i can be prevented.

In other words, the correction device 29i functions as a deformation prevention device for the lamp mounting device 2i that is attached to the construction part 9, such as the ceiling, during construction.

<Modification 2>
FIG. 31 is a cross-sectional view that typically shows a vertical cross section of the illumination device 1 according to the second modification of the third embodiment, perpendicular to the longitudinal direction X of the illumination device 1. As shown in FIG.

The correcting tool 29j is formed by selecting the material, composition, thickness, shape, etc. so that it has higher rigidity than the fixture body 20j. Therefore, the correcting tool 29j may be used as a member through which the hanging bolt 90 is inserted and which receives the nut 91 or washer 92 that is tightened to the hanging bolt 90. In this case, the correcting tool 29j is attached to the outer area of the fixture body 20j where the fixing device such as the hanging bolt 90 for attaching the lamp mounting fixture 2j to the ceiling, which is the construction part 9, is arranged. The correcting tool 29j is formed to have higher rigidity than the fixture body 20j, and the nut 91 or washer 92 is configured to be received only by the correcting tool 29j. Therefore, the lamp mounting fixture 2j including the fixture body 20j is less susceptible to the stress caused by tightening the nut 91, and deformation of the lamp mounting fixture 2j including the fixture body 20j can be prevented.

The correction device 29j therefore functions as a deformation prevention device for the lighting fixture mounting device 2j that is attached to the ceiling or other part of the construction section 9 during construction.
