Description

This disclosure relates to a lamp having a power supply unit and a lighting device having a lamp.

Conventionally, lighting fixtures have been proposed that include a light source unit having LEDs (light emitting diodes) mounted on one side of a substrate, and a lighting device located on the other side of the substrate that controls the lighting of the LEDs (see, for example, Patent Document 1).

In the lighting fixture disclosed in Patent Document 1, a terminal block is mounted in a through hole that connects one side of the board to the other side of the board. The terminal block has a first connection portion that is connected to the wiring pattern of the LED by soldering on one side of the board, and a second connection portion that is connected to a lead wire on the other side of the board. The lead wire is a power supply line that connects the second connection portion of the terminal block to the lighting device. The lighting device is supplied with power from an external AC power source, and functions as a power supply unit that controls the turning on and off of the LED via the lead wire and the terminal block. The lighting device is fixed to the other side of the mounting plate, opposite the side to which the light source unit is fixed. The lighting fixture disclosed in Patent Document 1 also has a terminal block cover. The terminal block cover is placed so as to cover the second connection portion of the terminal block, and is fixed to the other side of the mounting plate.

Patent No. 6446330

In the lighting fixture described in Patent Document 1, the lighting device and the terminal block are positioned apart, so the lead wire connecting the lighting device and the terminal block is long. Therefore, when assembling the lamp or installing the lighting fixture, if the lead wire gets caught on something and is pulled strongly, stress is applied to the connection part of the lead wire. As a result, the lead wire or each component connected to the connection part, such as the terminal block or lighting device, may be damaged. Or the lead wire may come off the terminal block or lighting device and break.

In addition, in the lighting fixture described in Patent Document 1, the lighting device, the terminal block, and the terminal block cover are each attached to the mounting plate separately using separate, independent parts. In other words, in the lighting fixture described in Patent Document 1, the lighting device, the terminal block, and the terminal block cover are configured to require complex assembly using many parts. This results in high material costs, assembly costs, and assembly work. In addition, the large amount of assembly work makes it easy for product quality to vary. Therefore, the lighting fixture described in Patent Document 1 needs to be further improved in terms of material costs, assembly costs, assembly work, and quality control. In the following, material costs, assembly costs, assembly work, and quality control will be collectively referred to as ease of assembly.

The present disclosure has been made to solve such problems, and aims to provide a lighting fixture and lighting device that improves assembly by enabling the power supply unit and power supply line to be attached to the base with a simple configuration.

The lighting fixture of the present disclosure comprises a light source unit having a light-emitting unit that emits light, a power supply unit that supplies power to the light-emitting unit to turn on the light-emitting unit, a base having a first surface and a second surface opposite to the first surface, with the light source unit arranged on the side of the first surface and the power supply unit arranged on the side of the second surface, an electric wire arranged via a through hole that penetrates the first surface and the second surface of the base, the electric wire having one end electrically connected to the light source unit and the other end electrically connected to the power supply unit, a holder attached to the base and having an electric wire holding portion that holds the electric wire and spaces it from the periphery of the through hole, and a power supply holding portion that holds a part of the power supply unit on the second surface , and the through hole has a shape corresponding to the holder .
Furthermore, the lighting fixture according to the present disclosure includes a light source unit having a light-emitting unit that emits light, a power supply unit that supplies power to the light-emitting unit to turn on the light-emitting unit, a base having a first surface and a second surface opposite to the first surface, with the light source unit arranged on the side of the first surface and the power supply unit arranged on the side of the second surface, an electric wire arranged via a through hole that penetrates the first surface and the second surface of the base, one end of which is electrically connected to the light source unit and the other end of which is electrically connected to the power supply unit, and a holder that is attached to the base and has an electric wire holding portion that holds the electric wire and separates it from the periphery of the through hole, and a power supply holding portion that holds a part of the power supply unit on the second surface, the holder being composed of two parts, a first holder and a second holder, the first holder and the second holder being fixed to the base in an integrated state, and the power supply unit being held by the holder in a state where the first holder and the second holder of the holder are integrated.

According to the lamp and lighting device disclosed herein, the power supply unit and at least a portion of the power supply line are held on the base using a common holder, so that the power supply unit and the power supply line can be attached to the base with a simple configuration. This also simplifies the configuration of the lamp and lighting device, improving the ease of assembly of the lamp and lighting device.

Embodiment 1.
[Lighting device 1]
Fig. 1 is a perspective view showing a configuration example of a lighting device 1 according to embodiment 1. Fig. 2 is an exploded perspective view of the lighting device 1 shown in Fig. 1. The lighting device 1 is a device that is installed at a position where it can illuminate an illumination space and illuminates the illumination space. The illumination space is a space in which the lighting device 1 is installed, and means, for example, an internal space of a residential space or a warehouse, an internal space of a building or a public facility, a shared space such as an elevator or a corridor, or a space inside a vehicle such as a train or a ship.

As shown in Figs. 1 and 2, the lighting device 1 comprises an appliance 2 and a luminaire 3 that can be attached and detached to the appliance 2. The lighting device 1 is attached to an attachment portion 9 with the luminaire 3 facing the illumination space. The attachment portion 9 is an attachment location where the appliance 2 is attached, such as a ceiling or a wall. The lighting device 1 irradiates light from the luminaire 3 by turning on the luminaire 3, thereby illuminating the illumination space.

The lighting device 1 is a so-called inverted Mount Fuji type lighting device because the fixture end 21 is shaped like an inverted Mount Fuji. The lighting device 1, fixture 2, and luminaire 3 are all formed in an elongated shape. In the following description, the direction along the long side of the lighting device 1 is referred to as the long direction X, which is the first direction. The direction perpendicular to the long direction X and along the short side of the lighting device 1 is referred to as the short direction Y, which is the second direction. The direction perpendicular to both the long direction X and the short direction Y is referred to as the up-down direction Z, which is the third direction.

In the first embodiment, the up-down direction Z is, for example, the vertical direction. In the up-down direction Z, the direction toward the mounting portion 9 to which the lighting device 1 is mounted, i.e., the ceiling or wall, is referred to as the upward direction Z1. The direction opposite to the upward direction Z1, toward the side of the illumination space to which light is irradiated from the lighting device 1, is referred to as the downward direction Z2. Here, the upward direction Z1 is the direction in which the lighting device 3 is mounted to the device 2. The downward direction Z2 is the direction in which the lighting device 3 is removed from the device 2.

[Apparatus 2]
The fixture 2 is a so-called direct-attach type lighting fixture that is directly attached to the attachment portion 9. The fixture 2 is attached to a fixture (not shown) such as a hanging bolt provided on the attachment portion 9. The fixture 2 is also an attachment member to which the lamp 3 is attached. Therefore, the fixture 2 is also called a lamp attachment fixture. The fixture 2 holds the lamp 3 attached to the fixture 2 and supplies power to the lamp 3.

The fixture 2 is a so-called V-type lighting fixture because it has two inclined surface portions 202 arranged in a V shape on both sides in the short direction Y of the lamp mounting portion 22 (see FIG. 2) described later. The fixture 2 is not limited to this, and may be a directly attached lighting fixture such as a trough type or a shaded type that does not have an inclined surface portion 202, or a recessed lighting fixture.

The device 2 is formed into a pre-designed shape by processing such as bending, roll forming, or pressing a metal plate (sheet metal). Alternatively, the device 2 may be formed by a manufacturing method such as extrusion molding using a metal material or three-dimensional modeling such as 3D printing.

The fixture 2 has a fixture body 20 that extends in the longitudinal direction X and fixture end portions 21 that are attached to both ends of the fixture body 20 in the longitudinal direction X. As shown in Figs. 1 and 2, the fixture end portions 21 have a trapezoidal shape. The longer side of the trapezoidal shape of the fixture end portion 21 is disposed on the side of the mounting portion 9, and the shorter side of the trapezoidal shape is disposed on the side of the lighting space.

(Apparatus body 20)
As shown in Fig. 2, the device main body 20 has a top surface 200, a pair of side surfaces 201, and a pair of inclined surfaces 202. The top surface 200 is formed in a long, flat plate shape along the longitudinal direction X. The top surface 200 is also referred to as a bottom surface of the device main body 20. A screw hole (not shown) and an electric wire insertion hole (not shown) are formed in the top surface 200. The top surface 200 is disposed so as to be approximately parallel to the mounting portion 9, such as a ceiling.

The pair of side portions 201 are disposed at both ends of the top surface portion 200 in the short direction Y. The pair of inclined surface portions 202 are disposed at both ends of the top surface portion 200 in the short direction Y so as to be on the outside of the pair of side portions 201. In this way, in the device main body portion 20, the pair of side portions 201 are disposed on the inside, and the pair of inclined surface portions 202 are disposed on the outside. The pair of side portions 201 and the pair of inclined surface portions 202 constitute the device side portions of the device main body portion 20.

Of both ends of the side portion 201 in the short direction Y, one end is disposed on the side of the top surface portion 200, and the other end is disposed on the side of the lighting space opposite the top surface portion 200. One end of the side portion 201 in the short direction Y is connected to one end of the top surface portion 200 in the short direction Y, and the other end of the side portion 201 in the short direction Y is connected to one end of the inclined surface portion 202 in the short direction Y. The side portion 201 is provided along the longitudinal direction X of the top surface portion 200 over the entire length of the side edge of the top surface portion 200. The side portion 201 rises from the side edge of the top surface portion 200 in a direction away from the mounting portion 9. That is, the side portion 201 protrudes downward Z2 from the side edge of the top surface portion 200.

As shown in FIG. 1, the inclined surface portion 202 is an inclined portion of the fixture body portion 20, and is a design part that determines the appearance of the lighting device 1 and the fixture 2. The inclined surface portion 202 extends along the longitudinal direction X of the fixture body portion 20. The inclined surface portion 202 constitutes the side surface of the fixture body portion 20. As described above, one end of the inclined surface portion 202 in the lateral direction Y is connected to one end of the side portion 201 on the side of the lighting space in the lateral direction Y. The inclined surface portion 202 is provided along the longitudinal direction X of the side portion 201, over the entire length of one end of the side portion 201 in the lateral direction Y. The inclined surface portion 202 is provided on both sides in the lateral direction Y of the lamp attachment portion 22 described later.

The inclined surface portion 202 is inclined with respect to the mounting portion 9, such as a ceiling. That is, the inclined surface portion 202 is inclined with respect to the top surface portion 200. The inclined surface portion 202 may be integral with the side surface portion 201. In this case, the inclined surface portion 202 is formed by bending the lower end of the side surface portion 201 diagonally upward. The inclined surface portion 202 is formed so as to move away from the side surface portion 201 as it moves toward the mounting portion 9. The inclined surface portion 202 may have the function of reflecting a portion of the light emitted from the lighting device 3 and distributing it laterally.

As shown in FIG. 2, the fixture body 20 has a lamp mounting section 22 inside. The lamp mounting section 22 forms a space in which at least a portion of the lamp 3 is housed. The lamp mounting section 22 is formed in a concave shape by the top surface 200 and a pair of side surfaces 201 of the fixture body 20. The lamp mounting section 22 is also formed in a box shape with an open bottom by the top surface 200, the pair of side surfaces 201, and the pair of fixture ends 21 of the fixture body 20.

The lamp mounting section 22 is provided with two springs 23, a terminal block 24, and a fixture side electric wire 25.

The springs 23 are fixture-side connectors. The two springs 23 are attached to the top surface 200 at a distance from each other so as to form a pair along the longitudinal direction X of the fixture body 20. When the lamp 3 is attached to the fixture 2, the springs 23 connect to a spring receiver 60, which is a fixture-side connector provided on the lamp 3. In other words, the lamp 3 is attached to the fixture 2 by connecting the springs 23 to the spring receiver 60. The springs 23 support the lamp 3 by engaging with the spring receiver 60.

The terminal block 24 serves as a relay device that supplies power supplied from an external power source to the lighting fixture 3. The fixture side electric wires 25 are electrically connected to the terminal block 24. The fixture side electric wires 25 include a power supply line and a control signal line. Power and control signals supplied from outside the fixture 2 are transmitted to the power supply unit 40 of the lighting fixture 3 via the terminal block 24 and the fixture side electric wires 25.

(Instrument End 21)
The pair of instrument ends 21 are plate-like members arranged at both ends in the longitudinal direction X of the instrument body 20. As shown in Fig. 2, the main surface of the instrument end 21 has a trapezoidal shape, with the length of the upper side being longer than the length of the lower side. The instrument end 21 is abutted against and connected to both ends in the longitudinal direction X of the top surface 200 and both ends in the longitudinal direction X of the inclined surface 202. In addition, each of the instrument ends 21 is formed with a knockout portion 210.

The knockout portion 210 is a portion of the fixture end 21 that has been subjected to knockout processing. The knockout portion 210 is formed so as to be easily detachable from the fixture end 21. When constructing the lighting device, a worker can easily provide a penetration portion in the fixture end 21 at the site by knocking out the knockout portion 210 or cutting it off. When the knockout portion 210 is removed from the fixture end 21, it functions as an insertion port for a power line (not shown) that is passed between adjacent fixtures 2, for example. Since the knockout portion 210 is disposed at both ends in the longitudinal direction X of the fixture body 20, the worker can select one of the two knockout portions 210 to provide a penetration portion in the fixture end 21. In this case, by providing multiple knockout portions 210 in the fixture end 21, the worker can freely select the insertion port for the power line to be inserted into the fixture 2 according to the construction environment at the site.

[Lamp 3]
FIG. 3 is a perspective view of the lamp 3 shown in FIG. 2 as viewed from the side of the mounting portion 9. FIG. 4 is an exploded perspective view of the lamp 3 shown in FIG. 3. FIG. 5 is a partial perspective view of the lamp 3 for explaining the holder 50 according to the first embodiment. In FIG. 5, the up-down direction Z is opposite to that in FIGS. 1 to 4. That is, the downward direction Z2 in FIGS. 1 to 4 is indicated by an upward arrow in FIG. 5. The lamp 3 will be explained using FIGS. 1 to 5. The lamp 3 irradiates light toward the illumination space when attached to the lamp mounting portion 22 of the device 2. The lamp 3 is also called a lighting device or a light unit.

As described above, the lighting fixture 3 is attached to the fixture 2 for use. The lighting fixture 3 of the first embodiment is formed in an elongated shape and is detachably attached to the fixture 2. As shown in FIG. 2, the lighting fixture 3 has a light source unit 30 and a translucent outer casing 39. As shown in FIG. 3, the lighting fixture 3 also has a spring receiver 60, a lighting fixture side electric wire 70, an electric wire arrangement device 80, and a holder 50.

(Light source unit 30)
2 to 5, the light source unit 30 has a power supply unit 40 that generates lighting power, and a light source unit 31 (see FIGS. 2, 4, and 5). The light source unit 30 further has a base 34 (see FIGS. 3 to 5) that serves as a base on which the light source unit 31 is placed, and a power supply line 38 (see FIGS. 3 to 5) that supplies lighting power from the power supply unit 40 to the light source unit 31.

(Power supply unit 40)
The power supply unit 40 constitutes a power supply device and a control unit. External power from an external power source such as a commercial power source is supplied to the power supply unit 40 via a terminal block 24 (see FIG. 2) arranged on the device 2. The power supply unit 40 converts the external power into lighting power for lighting the light emitting unit 33 of the light source unit 31, and supplies the lighting power to the light source unit 31 (see FIG. 2).

In the lighting device 1 of the first embodiment, as shown in FIG. 4 and FIG. 5, the power supply unit 40 has a power supply unit 44 (see FIG. 20 and FIG. 21), and a power supply case 42 and a power supply cover 43 to accommodate the power supply unit 44. The power supply case 42 and the power supply cover 43 are a power supply housing in which the power supply unit 44 is arranged. The power supply case 42 is the main body of the power supply housing, and the power supply cover 43 is the cover of the power supply housing. The power supply case 42 is attached to the second surface 342 of the base 34 using a fastener 85 such as a screw, as shown in FIG. 4. As a result, the power supply unit 40 is accommodated in the lamp mounting portion 22 together with the light source unit 31 and the like. The base 34 is provided with a screw insertion hole 354 and a power supply fixing portion 356, as shown in FIG. 4. The power supply fixing portion 356 has a circular shape when viewed from above, and the screw insertion hole 354 is formed in the center thereof. As shown in FIG. 4, the fixing device 85 is inserted into the screw insertion hole 354 in the upward Z1 direction and fastened, thereby fixing the power supply unit 40 to the base 34. The power supply unit 40 has a rectangular box shape extending in the longitudinal direction X, and an output terminal 41 is provided at one end in the longitudinal direction X. The output terminal 41 is electrically connected to a conductor 382, which is the core wire of the power supply line 38 described below. The power supply unit 40 is disposed between the second surface 342 of the base 34 and the fixture 2 when the lighting fixture 3 is attached to the fixture 2.

The power supply unit 40 also has an insertion piece 420 provided on the power supply case 42, as shown in Figs. 20 to 22, which will be described later. The insertion piece 420 is a protrusion that protrudes from one end of the power supply case 42 in the longitudinal direction X toward the longitudinal direction X. The insertion piece 420 is provided at one end of the power supply case 42 in the longitudinal direction X on the side where the output terminal 41 is provided. When the power supply unit 40 is fixed to the base 34, the insertion piece 420 provided on the power supply unit 40 is inserted into the power supply holding portion 556 (see Fig. 22) of the holder 50, which will be described later. As a result, the power supply unit 40 is fixed to the base 34 not only by the fixing device 85 but also by the holder 50, so that it is more reliably prevented from falling off the base 34. The method of connecting the power supply unit 40 to the holder 50, which will be described later, will be described later with reference to Figs. 20 to 23.

(Light source unit 31)
The light source unit 31 is a light-emitting unit that emits light. As shown in Fig. 5, the light source unit 31 includes a light-emitting unit 33 that emits light using lighting power supplied from a power supply unit, a substrate 32 on which the light-emitting unit 33 is provided, and a power receiving unit 324 that supplies lighting power to the light-emitting unit 33. Note that the light-emitting unit 33 is provided on a mounting surface, which is one surface of the substrate 32, as shown in Fig. 2.

The light-emitting unit 33 emits light upon receiving lighting power supplied from the power supply unit 40 via the power supply line 38. The light-emitting unit 33 is a surface-mounted component. The light-emitting unit 33 is, for example, a light-emitting element such as a light-emitting diode (LED). The light-emitting unit 33 is mounted on a board using a connecting member such as solder. In the first embodiment, the light-emitting unit 33 is described as being a light-emitting element, but the light-emitting unit 33 is not limited to being a light-emitting element. For example, the light-emitting unit 33 may be an element such as a solid-state laser, a semiconductor laser, an organic electroluminescence (EL), or an inorganic electroluminescence (EL). The light-emitting unit 33 may be a combination of a light-emitting element and another light source.

The substrate 32 is formed in an elongated shape extending along the longitudinal direction X. The substrate 32 has a plate-like shape and has one surface 320 on which the light-emitting unit 33 is arranged, and the other surface 321 which is the surface opposite to the one surface 320. The one surface 320 is the mounting surface of the light-emitting unit 33, and is the lower surface of the substrate 32 on the side of the irradiation space, and is the surface facing the side of the irradiation space. In the configuration example shown in FIG. 1, a plurality of light-emitting units 33 are mounted in a row on the one surface 320 of the substrate 32. However, the mounting form of the light-emitting units 33 is not limited to this configuration. The other surface 321 is the non-mounting surface of the light-emitting unit 33 and is the upper surface of the substrate 32. The other surface 321 is the joint surface with the base 34. In this way, the other surface 321 constitutes the surface on the side of the mounting portion 9 in the light source unit 30.

The substrate 32 may be of either a rigid type or a flexible type. For example, a glass-epoxy substrate (FR-4), a glass-composite substrate (CEM-3), a paper-epoxy substrate (FR-3), a paper-phenol substrate (XPC), or a metal-based substrate may be used for the substrate 32. The other surface 321 of the substrate 32 is attached to the first surface 341 of the base 34. More specifically, the substrate 32 is bonded and fixed to the first surface 341 of the base 34 using an adhesive member 87 with the other surface 321 facing the first surface 341 of the base 34. Although not shown, the substrate 32 may be fixed to the base 34 using a fastener such as a rivet or a screw, or may be fixed by a substrate holder provided by cutting and raising a part of the base 34.

The substrate 32 is formed with a substrate through hole 322 that penetrates the substrate 32. The substrate through hole 322 is formed to match the position of the power supply line 38, as shown in Figures 4 and 5. More specifically, the substrate through hole 322 is formed in a position that overlaps with a first guide portion 543 of the holder 50 described later in a direction perpendicular to one surface 320 of the substrate 32, i.e., in the vertical direction Z.

The conductor 382 at one end 380 (see FIG. 5) of the power supply line 38 is inserted into the board through hole 322. The conductor 382 is the core wire of the power supply line 38.

The power receiving section 324 is formed around the board through hole 322 on the board 32. That is, the power receiving section 324 is provided on the board 32. The power receiving section 324 is a connection section on the board 32 to which the conductor 382 is connected. The power receiving section 324 is also called a connection pad. The conductor 382 at one end 380 of the power supply line 38 is connected to the power receiving section 324 using a connection member such as solder (not shown). The power receiving section 324 serves as an electrode that relays the lighting power supplied from the power supply section 40 to the light source section 31. The power receiving section 324 is provided on at least one of the one surface 320 and the other surface 321 of the board 32.

(Base 34)
The base 34 has a first surface 341 that faces the other surface 321 of the substrate 32 and supports the light source unit 31, and a second surface 342 that faces the opposite side of the first surface 341 and supports the power supply unit 40. The first surface 341 is the front surface of the base 34 and is a light source arrangement surface. The first surface 341 is a surface on the downward Z2 side and is also called the lower surface of the base 34. The first surface 341 constitutes a surface on the side of the irradiation space and faces the translucent portion 391 of the outer casing 39. The second surface 342 is a back surface of the base 34 and is a power supply arrangement surface. The second surface 342 is a surface on the upward Z1 side and is also called the upper surface of the base 34. The second surface 342 constitutes a surface on the side of the attachment portion 9 in the lighting device 1, and faces the top surface 200 of the fixture body 20 when the lamp 3 is attached to the fixture 2. The light source unit 31 is attached to the first surface 341 of the base 34 .

The base 34 is an elongated structure extending in the longitudinal direction X. The base 34 has a placement portion 340 and a side portion 343 that is combined with the outer casing portion 39 of the above-mentioned lighting device 3. The placement portion 340 is formed in a plate shape and has a first surface 341 that supports the light source portion 31 and a second surface 342 that supports the power supply portion 40. The side portion 343 rises from the end of the second surface 342 of the placement portion 340 in the Y direction toward the mounting portion 9. Therefore, the end of the base 34 in the longitudinal direction X has a U-shape. The base 34 is a base for the light source portion 31, the power supply portion 40, etc., and is a support member for the light source portion 31, the power supply portion 40, etc. The base 34 is also called a base, a chassis, or a mounting member. The arrangement section 340 is a base on which the light source section 31, the power supply section 40, etc. are arranged on the first surface 341 or the second surface 342.

As shown in FIG. 5, the base 34 has an electric wire insertion hole 363 formed therein, which penetrates the placement portion 340 of the base 34. The electric wire insertion hole 363 is a through hole that penetrates the first surface 341 and the second surface 342 of the base 34. The electric wire insertion hole 363 is also referred to as an electric wire holder attachment hole.

As shown in FIG. 5, the base 34 has a holder attachment portion 360. The holder attachment portion 360 is a portion to which the holder 50 described below is attached. More specifically, a protrusion 361 that protrudes toward the second surface 342 is formed in the placement portion 340 of the base 34. In FIG. 5, the protrusion 361 is a recessed portion (concave portion) because it is viewed from the first surface 341 side of the base 34. The top portion 362, which is the tip of the protrusion 361, has the above-mentioned electric wire insertion hole 363 formed therein. The protrusion 361, the top portion 362, and the electric wire insertion hole 363 constitute the holder attachment portion 360.

The top 362 is formed in a generally rectangular frame shape when viewed perpendicularly to the first surface 341 (vertical direction Z), i.e., in a plan view. The wire insertion hole 363 is formed by the edge of the top 362, and is formed in a rectangular shape by the edge of the top 362 in a plan view. However, the shapes of the top 362 and the wire insertion hole 363 need only correspond to the shape of the holder 50, and are not limited to this shape.

The protrusion 361 protrudes toward the second surface 342 of the arrangement portion 340, and forms a recessed portion (concave portion) on the first surface 341 side. That is, in the protrusion 361 of the base 34, a step is formed between the top 362 and the first surface 341. That is, the top 362 is recessed with respect to the first surface 341. On the other hand, on the second surface 342 side, the protrusion 361 forms a portion that protrudes with respect to the second surface 342. That is, the protrusion 361 is formed in a convex shape on the arrangement portion 340 on the second surface 342 side. In the protrusion 361 of the base 34, a step is formed between the top 362 and the second surface 342. That is, the top 362 protrudes from the second surface 342 toward the upward Z1 in the vertical direction Z.

Here, the base 34 is formed by bending a metal plate such as a steel plate, and is bent by a processing method such as roll forming or press molding to obtain rigidity. However, the base 34 is not limited to being formed by bending a metal plate, and may be formed using a material other than metal, such as resin or ceramic. The base 34 may also be processed by a processing method such as extrusion molding or three-dimensional modeling such as 3D printing. Furthermore, although not shown, the base 34 may be surface-treated or a functional member may be laid on the base 34 in order to improve the heat dissipation efficiency (thermal emissivity) or the light utilization efficiency (reflectance).

(Power supply line 38)
As shown in Fig. 4, the power supply line 38 serves as a supply path for supplying lighting power from the power supply unit 40 to the light source unit 31. As shown in Fig. 5, the power supply line 38 is arranged via a wire insertion hole 363, which is a through hole formed in the base 34, and electrically connects the power supply unit 40 and the light source unit 31. The power supply line 38 is configured by covering a conductor 382 with an exterior 383. The exterior 383 is an electrically insulating coating that covers the conductor 382 and is an insulating part that insulates the conductor 382.

The power supply line 38 passes through the power supply line insertion hole 363, and one end 380 is electrically connected to the light source unit 31, and the other end 381 is disposed on the second surface 342 side. The conductor 382 of the one end 380 of the power supply line 38 is connected to the power receiving unit 324 formed on the substrate 32.

The holder 50 is attached to the holder attachment portion 360 so as to be fitted into the electric wire insertion hole 363. The holder 50 has electrical insulation properties. The holder 50 is made of, for example, resin. The power supply line 38 is held by the holder 50. The holder 50 is disposed between the power supply line 38 and the top 362 of the electric wire insertion hole 363, so that contact and short circuit between the power supply line 38 and the top 362 can be prevented.

The first mounting portion 393 is also referred to as a support portion, and the second mounting portion 394 is also referred to as a locking portion.

The cover end 395 is a portion that covers the end of the lamp 3 in the longitudinal direction X. Here, the cover end 395 is formed as a separate member and attached to the light-transmitting portion 391 by welding, adhesion, or the like. The cover end 395 fits into the end opening of the space formed by the light-transmitting portion 391 of the outer shell 39 and the arrangement portion 340 of the base 34, and closes the end opening. However, the configuration of the outer shell 39 is not limited to this configuration, and the cover end 395, the light-transmitting portion 391, and the attachment portion 392 of the outer shell 39 may be formed integrally.

The outer shell 39 can be formed using a light-transmitting material such as synthetic resins such as polycarbonate (PC), acrylic (PMMA), or polypropylene (PP), or a material such as glass. The outer shell 39 can be formed using these materials by employing a method such as injection molding, blow molding, extrusion molding, or three-dimensional modeling. At least a part of the outer shell 39 may have any one of a diffusion function, a wavelength discrimination function, or a light blocking function, depending on the specifications of the lighting device 1.

When the power supply unit 40 is fixed to the base 34 with the first connection part 542 and the second connection part 552, which are the holder connection parts, positioned in the electric wire insertion hole 363, the end part in the longitudinal direction X of the power supply case 42 slides until it is inserted into the second fixing part 561 and abuts against the holder 50. Then, the holder 50 slides toward the opposite side to the power supply unit 40 in the longitudinal direction X until the first connection part 542 abuts against the edge part of the top part 362 that forms the electric wire insertion hole 363.

The holder 50 is fixed to the base 34 by clamping a part of the base 34 to the first fixing part 560. The holder 50 is also fixed to the base 34 by clamping a part of the power supply case 42 of the power supply unit 40, which is fixed to the base 34, to the second fixing part 561.

In detail, with the first connection portion 542 abutting the edge of the electric wire insertion hole 363, at least a part of the top 362 is fitted into the first fixing portion 560. In other words, at least a part of the top 362, which is the edge of the electric wire insertion hole 363, is arranged between the holder base and the holder main body, and the holder 50 is fixed to the arrangement portion 340 of the base 34 with its movement along the direction penetrating the electric wire insertion hole 363 restricted. Also, with the power supply unit 40 fixed to the base 34, the end of the power supply case 42 in the longitudinal direction X is fitted into the second fixing portion 561. In other words, at least a part of the power supply case 42 fixed to the base 34 is arranged between the holder base and the holder main body, and the holder 50 is fixed to the arrangement portion 340 of the base 34 with its movement along the direction penetrating the electric wire insertion hole 363 restricted.

(Power supply holding part 556)
Next, the power supply holding portion 556 provided in the holder 50 will be described mainly with reference to Figs. 20 to 23. As described above, Figs. 20 to 23 show the lighting device 3 according to the first embodiment. 20 and 22 show a state before the power supply unit 40 is held by the holder 50, and FIGS. 4 shows a state in which the power supply unit 40 is held by the holder 50.

As shown in Figs. 8 and 22, the holder connection portion of the holder 50 is provided with a power supply holding portion 556. As shown in Figs. 8 and 22, the power supply holding portion 556 is a recess or a through hole formed in the second holder 55 of the holder 50. At least a part of the power supply unit 40 is inserted into the power supply holding portion 556, and the power supply unit 40 holds the part. As shown in Figs. 20 and 22, the power supply unit 40 is provided with an insertion piece 420 at the end of the power supply case 42 on the side of the holder 50. The power supply holding portion 556 has a complementary shape to the insertion piece 420. The power supply holding portion 556 is retreated from the end of the second connection portion 552 of the second holder 55 opposite the first holder 54 along the longitudinal direction X to the side of the second opposing portion 557 by a distance greater than L2. The power supply holding portion 556 functions as an insertion piece insertion hole into which the insertion piece 420 is inserted. When the power supply unit 40 is attached to the base 34, the plug-in piece 420 of the power supply unit 40 is inserted into the power supply holding portion 556 of the holder 50.

Furthermore, as described above, the base 34 is provided with a screw insertion hole 354 and a power supply fixing portion 356, as shown in FIG. 4. The power supply case 42 is provided with a screw insertion hole 421, as shown in FIGS. 4 and 5. As shown in FIGS. 4 and 5, a fastener 85 such as a screw is inserted into the screw insertion hole 354 of the base 34 and the screw insertion hole 421 of the power supply case 42 to fasten them together. The power supply case 42 is fixed to the base 34 by both the power supply holding portion 556 of the holder 50 and the fastener 85.

In this way, the plug-in piece 420, which is part of the power supply unit 40, is held by the power supply holding portion 556 of the holder 50. Furthermore, the remaining parts of the power supply unit 40, excluding the part in question, are fixed to the base 34 by the fixing device 85. In this way, by fixing the remaining parts of the power supply unit 40 to the base 34 with the fixing device 85, the state in which the plug-in piece 420, which is part of the power supply unit 40, is held by the holder 50 is maintained. Furthermore, the holder 50 is fixed to the base 34 with the power supply unit 40 attached to the base 34. This restricts movement of the power supply unit 40.

(Procedure for holding and connecting the power supply line 38)
The procedure for holding the power feeder 38 according to the first embodiment will be described with reference to Fig. 5 and Figs. 10 to 19. Fig. 5 shows a state before the power feeder 38 is held. Fig. 10 is a perspective view showing a state before the holder 50 is attached to the base 34 after the power feeder 38 is held. Fig. 11 is a perspective view showing a state after the holder 50 is attached to the base 34. Fig. 12 is a perspective view showing a state before the substrate 32 is placed on the base 34. Fig. 13 is a perspective view showing a state after the substrate 32 is placed on the base 34.

(Step 1)
5, a holder attachment portion 360 is formed on the base 34. The holder attachment portion 360 includes an electric wire insertion hole 363. The holder 50 is attached so as not to protrude from the first surface 341 side of the base 34. Therefore, a protruding portion 361 that protrudes toward the second surface 342 side is provided on the portion of the base 34 where the holder 50 is attached by drawing or the like, and an electric wire insertion hole 363 that is a through hole is provided at a top portion 362 of the protruding portion 361. The holder 50 is disposed within the electric wire insertion hole 363.

(Step 2)
As shown in FIG. 5, the first holder 54 and the second holder 55 are disposed facing each other so as to sandwich the power supply line 38. Thereafter, the first holder 54 and the second holder 55 are engaged with each other. At this time, the first engagement portion 545 (see FIG. 7) provided on the first holder 54 is fitted into the positioning hole 558 (see FIG. 9) provided on the second holder 55. This allows the first holder 54 and the second holder 55 to be positioned. Also, when the first engagement portion 545 is fitted into the positioning hole 558, the second engagement portion 555 (see FIG. 15), which is an engagement claw provided on the second holder 55, is inserted into the engagement claw insertion hole 548 (see FIG. 15) provided on the first holder 54. This allows the second engagement portion 555 to be engaged with the engagement claw insertion hole 548. As a result, the first holder 54 and the second holder 55 become an integral and inseparable holder 50 as shown in FIG.

At this time, as shown in FIG. 10, one end 380 of the power supply line 38 is exposed from the holder 50 toward the outside. In FIG. 10, the exterior 383 of the one end 380 of the power supply line 38 is removed, and the conductor 382 is exposed to the outside. However, this is not limited to this, and the exterior 383 may be left at this stage, and the exterior 383 of the one end 380 of the power supply line 38 may be removed in step 5 described later. The same is true for the exterior 383 of the other end 381 of the power supply line 38. The power supply line 38 is pressed from both sides by the first holder 54 (see FIG. 16) provided on the first holder 54 and the second holder 55 (see FIG. 16) provided on the second holder 55, as shown in FIG. 19, and the movement is restricted. Therefore, the power supply line 38 does not fall off the holder 50.

(Step 3)
10 and 11 , the holder 50 is inserted into the electric wire insertion hole 363 of the holder attachment portion 360 provided on the base 34 from the side of the first surface 341 of the base 34. The maximum dimension of the holder base, i.e., the maximum dimension of the first base portion 540 provided on the first holder 54 and the second base portion 550 provided on the second holder 55 combined, is larger than the maximum dimension of the electric wire insertion hole 363. Therefore, the first base portion 540 and the second base portion 550 constituting the holder base do not pass through the electric wire insertion hole 363. In other words, the first base portion 540 and the second base portion 550 abut against the edge portion of the top portion 362 of the holder attachment portion 360, so that the holder 50 remains on the side of the first surface 341 of the base 34 and movement toward the side of the second surface 342 is restricted.

5, the protrusion 361 of the holder attachment portion 360 is a convex portion that protrudes from the first surface 341 side of the base 34 toward the second surface 342 side. Therefore, when viewed from the first surface 341 side of the base 34, the protrusion 361 is a recessed portion (concave portion). The first base 540 and the second base 550, which are the holder bases of the holder 50, are stored in the recessed portion (concave portion) as shown in FIG. 11. As a result, the first base 540 and the second base 550 of the holder 50 do not protrude in the downward Z2 direction in the up-down direction Z from the first surface 341 of the base 34.

(Step 4)
12 and 13, the substrate 32 is bonded and fixed to the first surface 341 of the base 34 using an adhesive member 87 such as an adhesive. At this time, the position of the substrate 32 is determined in accordance with the position of the holder 50 determined by fixing the power supply unit 40 to the base 34. More specifically, the position of the substrate 32 is determined so that the first guide portion 543 of the first holder 54 overlaps with the substrate through hole 322 provided in the substrate 32 in the longitudinal direction X and the lateral direction Y. As a result, as shown in FIG. 13, the conductor 382 of the power supply line 38 protrudes from the substrate through hole 322 of the substrate 32 toward the downward direction Z2 in the up-down direction Z. Note that, instead of the adhesive, other adhesive members such as an adhesive sheet or fixing members such as screws and rivets may be used to fix the substrate 32 to the base 34.

At this time, the first base 540 and the second base 550, which are the holder bases of the holder 50, are stored in the recessed portion (concave portion) on the first surface 341 side of the protrusion 361 as described above, and therefore do not interfere with adhesively fixing the substrate 32 to the base 34. Also, in this state, the first base 540 and the second base 550 of the holder 50 are disposed between the base 34 and the substrate 32. Therefore, by adhesively fixing the substrate 32 to the base 34, the holder 50 is covered by the substrate 32, and thus it is possible to prevent the holder 50 from falling off the base 34.

(Step 5)
The conductor 382 of one end 380 of the power supply line 38 and the power receiving unit 324 attached to the board through hole 322 of the board 32 are electrically connected using a connecting member such as solder (not shown). As described above, the power receiving unit 324 is a connection pad. If the one end 380 of the power supply line 38 remains covered with the exterior 383 when connecting the power supply line 38 and the power receiving unit 324, the exterior 383 of the one end 380 of the power supply line 38 is removed to expose the conductor 382 to the outside before starting the connection work.

At this time, since the power supply line 38 is held by the holder 50 fixed to the base 34, the connection between the conductor 382 and the power receiving unit 324 can be stably performed. This allows the connection between the conductor 382 and the power receiving unit 324 to have high quality.

At this time, since the holder 50 is present between the power supply line 38 and the base 34, the power supply line 38 does not come into contact with the base 34. More specifically, the holder 50 prevents the power supply line 38 from coming into contact with the edge of the electric wire insertion hole 363 provided in the base 34. This prevents damage to the exterior 383 of the power supply line 38 caused by the edge of the electric wire insertion hole 363, and prevents a short circuit between the conductor 382 of the power supply line 38 and the edge of the electric wire insertion hole 363.

In the first embodiment, as described above, the conductor 382 is exposed at one end 380 of the power supply line 38, and the conductor 382 is electrically connected to the power receiving unit 324 of the substrate 32. Note that the connection between the power supply line 38 and the power receiving unit 324 is not limited to this. For example, a connection part such as a terminal or connector may be attached to the one end 380 in advance, and the connection part may be electrically connected to the power receiving unit 324 of the substrate 32.

Furthermore, in the first embodiment, one end 380 of the power feeder 38 is shown to pass through the substrate 32. However, the relationship between the power feeder 38 and the substrate 32 is not limited to this. For example, the one end 380 of the power feeder 38 and the power receiving unit 324 may be arranged on a path that does not pass through the substrate 32. Furthermore, in the first embodiment, one end 380 of the power feeder 38 and the power receiving unit 324 are shown to be connected on the one surface 320 side of the substrate 32. However, this is not limited to this. For example, the one end 380 of the power feeder 38 and the power receiving unit 324 may be connected on the other surface 321 side of the substrate 32.

(Step 6)
4, the conductor 382 of the other end 381 of the power supply line 38 is inserted into the output terminal 41 of the power supply unit 40, and the power supply line 38 is electrically connected to the power supply unit 40. Note that the connection between the conductor 382 of the other end 381 of the power supply line 38 and the output terminal 41 of the power supply unit 40 is not limited to this. For example, a connecting part such as a terminal or a connector may be attached to the other end 381 in advance, and the connecting part may be electrically connected to the output terminal 41 of the power supply unit 40.

As described above, in step 2, the power supply line 38 is held by the holder 50. In this state, the power supply line 38 is fixed to the base 34 in step 3. Furthermore, in step 4, the board 32 is adhered to the base 34. In this way, since the power supply line 38 is held by the holder 50, it is possible to prevent stress from being applied to the connection portion between the power supply line 38 and the power receiving part 324 during the connection in step 6, the assembly of the lamp 3, and the use of the lamp 3.

In this way, the holder 50 is attached to the holder attachment portion 360 of the base 34 while holding the power supply line 38. At this time, as shown in FIG. 10, the conductor 382 of one end 380 of the power supply line 38 is exposed from the holder 50. Also, as shown in FIG. 11, the first base 540 of the first holder 54 and the second base 550 of the second holder 55 fit into the recessed portion (concave) on the first surface 341 side of the protrusion 361 formed on the base 34. Therefore, as shown in FIG. 13, when the substrate 32 is attached to the base 34, the first base 540 and the second base 550 do not interfere with the attachment of the substrate 32.

The substrate 32 is fixed to the first surface 341 of the base 34 using an adhesive material 87 such as an adhesive, with the conductor 382 of one end 380 of the power supply line 38 passing through the substrate through hole 322.

The holder 50 has a first body 511 with a first guide portion 543 having a first insertion portion 5431, and a second body 551 with a second guide portion 553. With the power supply line 38 inserted into the first insertion portion 5431 of the first guide portion 543, the second guide portion 553 is attached to the first guide portion 543, thereby restricting the movement of the power supply line 38.

When the holder 50 is attached to the base 34, the first guide portion 543 and the second guide portion 553 are arranged adjacent to each other along the longitudinal direction X of the first surface 341 of the base 34.

(Procedure for holding the power supply unit 40)
The procedure for holding the power supply unit 40 according to the first embodiment will be described with reference to FIGS.

(Step 1)
As shown in FIG. 20, the holder 50 is placed on the holder attachment portion 360 of the base 34 .

(Step 2)
Next, as shown in Fig. 20 and Fig. 21, the power supply unit 40 is slid in the direction of the arrow A, and the plug-in piece 420 provided on the power supply case 42 of the power supply unit 40 is inserted into the power supply holding part 556 of the holder 50. This connects the power supply case 42 of the power supply unit 40 and the holder 50. With the plug-in piece 420 inserted into the power supply holding part 556, the power supply unit 40 is further slid in the direction of the arrow A, and the holder 50 is fixed to the holder attachment part 360 of the base 34. At this time, the holder attachment part 360 (the edge part of the top part 362) and the first fixing part 560 overlap by the dimension L1, and the holder 50 is restricted from moving in the direction penetrating the electric wire insertion hole 363. In this way, the holder 50 connected to the power supply unit 40 is fixed to the base 34.

(Step 3)
Next, with the power supply case 42 of the power supply unit 40 and the retaining device 50 connected, as shown in Figures 4 and 5, a fastener 85 such as a screw is inserted into the screw insertion hole 354 of the power supply fixing part 356 and then into the screw insertion hole 421 of the power supply case 42 to fasten them together.

In the above steps 1 and 2, the insertion piece 420 is inserted into the power supply holding portion 556 and then the holder 50 is fixed to the base 34. However, this is not limiting. Only the holder 50 placed on the holder attachment portion 360 of the base 34 in step 1 may be slid in the direction of arrow A and fixed to the holder attachment portion 360. In this case, the insertion piece 420 of the power supply unit 40 is connected to the power supply holding portion 556 of the holder 50 fixed to the holder attachment portion 360.

20 and 21, the above steps 1 to 3 may be performed with the power supply device 44 and power supply cover 43 of the power supply unit 40 attached to the power supply case 42 in advance. However, this is not limited to the above, and as shown in FIGS. 22 and 23, the above steps 1 and 2 may be performed without attaching the power supply device 44 and power supply cover 43 of the power supply unit 40 to the power supply case 42. In this case, after steps 1 to 3 are completed, the power supply device 44 and power supply cover 43 of the power supply unit 40 are attached to the power supply case 42. Then, although not shown in the drawings, the above steps 1 to 3 may be performed without attaching only the power supply cover 43 of the power supply unit 40 to the power supply case 42. In this case, after steps 1 to 3 are completed, the power supply cover 43 of the power supply unit 40 is attached to the power supply case 42.

As shown in Figures 20 to 23, in the first embodiment, when the power supply unit 40 is connected to the holder 50, a portion of the power supply case 42 other than the insertion piece 420 and the second fixing portion 561 of the holder 50 overlap by a dimension L2 along the longitudinal direction X.

[Functions and Effects of the Lighting Fixture 3 and the Lighting Device 1]
The lamp 3 according to the first embodiment includes a holder 50. The holder 50 is formed with a first insertion portion 5431 through which the power supply line 38 is inserted. The lamp 3 and the lighting device 1 also have a restricting portion consisting of a first holding portion 544 for restricting movement of the power supply line 38 disposed in the first insertion portion 5431 and a second holding portion 554 formed in the second holder 55. The holder 50 is inserted into the electric wire insertion hole 363, which is a through hole provided in the base 34, from the side of the first surface 341 of the base 34, and is attached to the base 34 in a state in which movement toward the side of the second surface 342 of the base 34 is restricted.

In the lighting fixture 3 according to the first embodiment, the power supply unit 40 and the power supply line 38 are held to the base 34 using a shared holder 50, so the configuration of the lighting fixture 3 and the lighting device 1 is simplified, and the assembly of the lighting fixture 3 and the lighting device 1 is improved.

The holder 50 is disposed on the side of the output terminal 41 of the power supply unit 40. Therefore, as shown in FIG. 3, the output terminal 41 of the power supply unit 40 and the holder 50 are disposed adjacent to each other. As a result, the length of the power supply line 38 disposed between the output terminal 41 and the holder 50 is much shorter than the conventional lead wire described in Patent Document 1 and the like. Therefore, the power supply line 38 is less likely to be pulled when assembling the lamp 3 or installing the lighting device 1.

In addition, even if the power supply line 38 is pulled during assembly of the lamp 3 or installation of the lighting device 1, the holder 50 can hold the power supply line 38 so that no stress is applied to the connection between the power supply line 38 and the substrate 32 and the connection between the power supply line 38 and the power supply unit 40. As a result, damage to the power supply line 38 or each component such as the power supply unit 40 connected to the power supply line 38 can be prevented. In addition, the power supply line 38 can be prevented from coming off the power supply unit 40, and the power supply line 38 can be prevented from being disconnected.

In addition, by having the retainer 50 of the above configuration, the lighting fixture 3 can prevent damage to the exterior 383 of the power supply line 38 caused by the edge of the wire insertion hole 363, and can also prevent a short circuit between the conductor 382 of the power supply line 38 and the edge of the wire insertion hole 363. In addition, by having the retainer 50 of the above configuration, the insulation performance between the exposed portion of the conductor 382 of the power supply line 38 and the base 34 can be ensured.

In addition, the power supply line 38 is held by the holder 50 configured as described above and fixed to the base 34, so that no stress is applied to the connection between the power supply line 38 and the power receiving part 324 when assembling the lamp 3 and installing the lighting device 1.

The power supply line 38 is attached to the holder 50 so as not to come into contact with the edge of the wire insertion hole 363, which is a through hole. Therefore, the lighting device 3 can prevent damage to the exterior 383 of the power supply line 38 caused by the edge of the wire insertion hole 363, and can also prevent a short circuit between the conductor 382 of the power supply line 38 and the edge of the wire insertion hole 363. Furthermore, by having the holder 50 configured as described above, the insulation performance between the exposed portion of the conductor 382 of the power supply line 38 and the base 34 can be ensured.

The holder 50 is attached to the base 34 so as to cover the electric wire insertion hole 363, which is a through hole. The maximum dimension of the first base portion 540 of the holder 50 is formed to be larger than the maximum dimension of the electric wire insertion hole 363. The maximum dimension of the second main body portion 551 of the holder 50 is formed to be larger than the maximum dimension of the electric wire insertion hole 363. Therefore, the first holder 54 and the second holder 55 do not fall off the electric wire insertion hole 363. That is, the first holder 54 and the second holder 55 abut against the edge portion of the electric wire insertion hole 363, so that the holder 50 remains on the side of the first surface 341 of the base 34 and movement toward the side of the second surface 342 is restricted.

In addition, the length dimension along the vertical direction Z of the first body part 541 of the first holder 54 and the second body part 551 of the second holder 55 is formed to be larger than the thickness dimension of the base 34. Therefore, the first body part 541 and the second body part 551 can be arranged between the edge of the electric wire insertion hole 363 and the power supply line 38. As a result, damage to the exterior 383 of the power supply line 38 by the edge of the electric wire insertion hole 363 can be prevented, and a short circuit between the conductor 382 of the power supply line 38 and the edge of the electric wire insertion hole 363 can be prevented. Furthermore, by providing the holder 50 of the above configuration, the insulation performance between the exposed part of the conductor 382 in the power supply line 38 and the base 34 can be ensured.

The holder 50 is attached to the base 34 with the power supply line 38 inserted through the first insertion portion 5431. Therefore, even if the power supply line 38 is pulled when assembling the lamp 3 or installing the lighting device 1, damage to the power supply line 38 or each component such as the power supply unit 40 connected to the power supply line 38 can be prevented. Furthermore, the power supply line 38 can be prevented from coming off the power supply unit 40, and the power supply line 38 can be prevented from being disconnected.

The first base 540 and the second base 550 are disposed between the base 34 and the substrate 32. Since the first base 540 and the second base 550 are covered by the substrate 32, the first base 540 and the second base 550 can be prevented from falling off the base 34.

In addition, with the power supply line 38 inserted into the first insertion portion 5431 of the first guide portion 543, the second main body portion 521 is attached inside the first guide portion 543, thereby restricting movement of the power supply line 38. Therefore, in the lighting fixture 3, even if the power supply line 38 is pulled during assembly of the lighting fixture 3 or installation of the lighting device 1, damage to the power supply line 38 or each component such as the power supply unit 40 connected to the power supply line 38 can be prevented. As a result, in the lighting fixture 3, the power supply line 38 can be prevented from coming off the power supply unit 40, and disconnection of the power supply line 38 can be prevented.

In addition, the first guide portion 543 and the second main body portion 551 are arranged adjacent to each other along the longitudinal direction X of the second surface 342 of the base 34 when the holder 50 is attached to the base 34. By providing the holder 50, the power supply line 38 is held and insulation between the conductor 382 of the power supply line 38 and the base 34 is ensured, so that the direction of the power supply line 38 can be freely selected from 360°.

The holder 50 also has a power supply holding part 556 that holds a part of the power supply unit 40. With the holder 50 attached to the base 34, a part of the power supply unit 40 is inserted into the power supply holding part 556, so that the power supply unit 40 is held on the base 34. The other part of the power supply unit 40 is attached to the base 34 with a fastener 85 such as a screw. In this way, by fixing the other part of the power supply unit 40 with the fastener 85, the holding state between the part of the power supply unit 40 and the holder 50 is maintained. In addition, by holding a part of the power supply unit 40 with the holder 50, the posture of the power supply unit 40 is easily maintained, so that the fastener 85 can be prevented from loosening due to aging. In this way, the synergistic effect of the power supply holding part 556 and the fastener 85 allows the power supply unit 40 to be stably fixed to the base 34.

The part of the power supply unit 40 is the plug-in piece 420 provided in the power supply case 42, and the power supply holding portion 556 is a plug-in piece insertion hole into which the plug-in piece 420 is inserted. This makes the work easy, as it is only necessary to insert the plug-in piece 420 into the power supply holding portion 556. In addition, the plug-in piece 420 can be molded integrally with the power supply case 42, making it easy and inexpensive to form.

In addition, since the lighting device 1 is equipped with a lamp 3, the effects of the lamp 3 described above can be achieved.

Embodiment 2.
The configuration of the holder 50 is different between the first and second embodiments. Hereinafter, the light source unit 30 and the holder 50 according to the second embodiment will be referred to as the light source unit 30a and the holder 50a to distinguish them from the light source unit 30 and the holder 50 according to the first embodiment. Other configurations of the lamp 3 according to the second embodiment are the same as those of the first embodiment, so they are denoted by the same reference numerals and their description will be omitted here.

Figure 31 is a perspective view showing the state in which the power supply line 38 is held by the holder 50. Figure 32 is a perspective view showing the state in which the power supply line 38 is connected to the power supply unit 40.

Figures 37 and 38 are perspective views showing the configuration of the power supply holding section 516 of the holder 50a provided in the lamp 3 according to embodiment 2. Figure 37 shows the state before the power supply section 40 is held by the holder 50a, and Figure 38 shows the state after the power supply section 40 is held by the holder 50a.

The holder 50a will be described below using Figures 24 to 38.

The holder 50a has a holder base portion arranged on the first surface 341 side of the base 34, a holder main body portion arranged on the second surface 342 side of the base 34, and a holder connection portion that connects the holder base portion and the holder main body portion and is arranged inside the electric wire insertion hole 363.

The holder 50a is a wire fixing device that holds the power supply line 38 and fixes it to the base 34 while holding the power supply line 38, and is also called a wire holder. The holder 50a is a power supply fixing device that fixes it to the base 34 while holding a part of the power supply unit 40, and is also called a power supply clamp. The holder 50a is made of an electrically insulating material. The holder 50a is made of resin, for example. The holder 50a is attached to the base 34 so as to cover the wire insertion hole 363, which is a through hole.

As shown in FIG. 24, the holder 50a of the second embodiment has a first holder 51 attached to the first surface 341 side of the base 34 and a second holder 52 attached to the second surface 342 side of the base 34. The first holder 51 is also called the first holder, and the second holder 52 is also called the second holder. In the above-mentioned first embodiment, the holder 50 is divided into two, left and right, along the vertical direction Z, but in the second embodiment, the holder 50a is divided into two, top and bottom, along the horizontal direction perpendicular to the vertical direction Z.

(First holder 51)
First, the first holder 51 will be described. The first holder 51 has a first base 510, a first main body 511, and a first connection 512. The first base 510 and the first main body 511 are connected to each other with the first connection 512 interposed therebetween and are formed as one body. The first holder 51 is arranged to fit in a recess (recess) of the holder attachment portion 360 on the first surface 341 side of the protrusion 361 formed on the base 34, and is configured such that a part of the first holder 51 passes through the electric wire insertion hole 363 and protrudes from the second surface 342. The first holder 51 has a first connection 512, which is a part that connects the first base 510 and the first main body 511, formed at the end of the first main body 511 on the first base 510 side.

The first base 510 is a holder base disposed on the first surface 341 side of the base 34. The first base 510 is also referred to as a first base portion or a base-side extension portion. The first base 510 is formed in a flat plate shape. As shown in FIG. 25, the first base 510 extends horizontally from the end of the first main body 511 in the vertical direction Z toward the outside in a brim-like manner. That is, the first base 510 is formed so as to extend from the end of the first main body 511 in the vertical direction Z in the longitudinal direction X and the lateral direction Y. In this way, the first base 510, which is a holder base, extends from the end of the first main body 511, which is a holder connection portion, in a direction parallel to the first surface 341 of the base 34, and is formed in a brim-like manner with respect to the first main body 511.

The first base 510 is housed in a recess (concave) formed by the protrusion 361 of the holder attachment part 360. The first base 510 is formed so that the maximum dimension in a direction along the surface of the arrangement part 340 in a plan view is larger than the maximum dimension of the electric wire insertion hole 363, which is a through hole. Therefore, when the holder 50a is attached to the base 34, the first base 510 faces the top 362 and abuts against the top 362. By the first base 510 abutting against the top 362, the movement of the holder 50a in the upward direction Z1, i.e., toward the attachment part 9 such as the ceiling, is restricted.

The first body 511 is formed to have a roughly rectangular parallelepiped external shape. The first body 511 is a holder body arranged on the side of the second surface 342 of the base 34. The first body 511 is also called a body side extension. The first body 511, which is the holder body, extends in a direction along the second surface 342 of the base 34 from the end on the side of the second surface 342 of the holder connection part. The first body 511 passes through the electric wire insertion hole 363 when the first holder 51 is attached to the base 34. For this reason, the first body 511 of the first holder 51 is formed so that the maximum dimension in the direction along the arrangement part 340, when viewed in the direction penetrating the electric wire insertion hole 363, is smaller than the maximum dimension of the electric wire insertion hole 363, which is a through hole. In other words, the first main body 511 is formed so that the maximum dimension in the direction along the arrangement portion 340 when viewed in the direction along the electric wire insertion hole 363 is smaller than the maximum dimension of the first base 510.

The first connection portion 512 is a holder connection portion that connects the first base portion 510, which is a holder base portion, and the first main body portion 511, which is a holder main body portion. The first connection portion 512 is arranged inside the electric wire insertion hole 363. For this reason, the first connection portion 512 is formed so that the maximum dimension in the direction along the arrangement portion 340, when viewed in the direction penetrating the electric wire insertion hole 363, is smaller than the maximum dimension of the electric wire insertion hole 363, which is a through hole. And, the first connection portion 512 is formed so that the minimum dimension in the direction along the arrangement portion 340, when viewed in the direction penetrating the electric wire insertion hole 363, is smaller than the maximum dimension of the first main body portion 511, which is the holder main body portion.

The length dimension of the first connection part 512, which is the holder connection part, along the direction in which it passes through the electric wire insertion hole 363 is formed to be greater than the thickness dimension of the base 34. Therefore, the first connection part 512 passes through the electric wire insertion hole 363, and at least a portion of it is disposed inside the electric wire insertion hole 363. Therefore, when the holder 50a is attached to the base 34, the first main body part 511 of the first holder 51 protrudes toward the second surface 342.

The first holder 51 is a first holder 5 which is a first restricting portion for restricting the movement of the power supply line 38.
14. The first holding portion 514 is formed in a protruding shape on a part of the upper surface 5111 of the first main body 511, as shown in FIG. 23. The first holding portion 514 is formed on the surface of the first main body 511 opposite to the side where the first base 510 is formed. The first holding portion 514 protrudes from the upper surface 5111 of the first main body 511 in the upward Z1 direction in the vertical direction Z. The first holding portion 514 is a pressing portion that presses the pair of power feed lines 38 by means of a second restricting portion formed on the second holder 52 when the first holder 51 and the second holder 52 are combined. The first holding portion 514 is a restricting portion that restricts the movement of the pair of power feed lines 38 by the pressing. The power feed lines 38 are held by the holder 50a by the first holding portion 514, and are fixed to the base 34 so as not to move.

When viewed in the direction penetrating the electric wire insertion hole 363, the first body part 511 of the first holder 51 is formed such that the maximum dimension in the direction along the arrangement part 340 is smaller than the maximum dimension of the second body part 521 of the second holder 52. Therefore, the first body part 511 is arranged inside the second body part 521. The second body part 521 is slidably attached to the first body part 511 as shown by the arrow B in FIG. 30.

As shown in FIG. 26, the first connection portion 512, which is the holder connection portion, has a groove-shaped engagement groove portion 519 formed on both side surfaces in the short direction Y. The engagement groove portion 519 is a groove formed between the first base portion 510 and the first main body portion 511 that is recessed toward the inside, and is formed to extend along the longitudinal direction X of the lighting device 1. The engagement groove portion 519 is engaged with an engagement flange portion 529, which is the second engagement portion 525 of the second holder 52 described later. The engagement groove portion 519 constitutes the first engagement portion 515. The end portion on the side where the first base portion 510 of the first main body portion 511, which is the main body portion side extension portion, is disposed, functions as the first engagement portion 515.

The first holder 51 is formed with a first guide portion 513 penetrating the first base portion 510, the first connection portion 512, and the first main body portion 511. The first guide portion 513 is formed with a first insertion portion 5131 that is an insertion portion for inserting the power supply line 38 along the vertical direction Z. The power supply line 38 is inserted into the first insertion portion 5131. The first insertion portion 5131 is a guide hole or guide groove that guides the power supply line 38. As shown in FIG. 24, the first guide portion 513 is cylindrical, formed inside the first main body portion 511, and formed integrally with the first main body portion 511. The first insertion portion 5131 is formed along the cylindrical axis direction of the first guide portion 513. One end 380 of the power supply line 38 is arranged on the first surface 341 side of the arrangement section 340 via the first guide section 513, and the other end 381 is arranged on the second surface 342 side of the arrangement section 340. The other end 381 of the power supply line 38 is guided to the first holding section 514 via the first guide section 513. The other end 381 of the power supply line 38 is guided to the second holding section 524 via the first guide section 513. A part of the end 5132 of the first guide section 513 on the opposite side to the first base section 510 functions as a first restricting section that holds the power supply line 38 together with the second restricting section.

(Second holder 52)
Next, the second holder 52 will be described. FIG. 28 is a perspective view showing the internal structure of the second holder 52. FIG. 29 is a perspective view showing the appearance of the second holder 52. As shown in FIG. 24, the second holder 52 is generally formed in a C-shape in a cross section perpendicular to the longitudinal direction X. The second holder 52 has a second main body 521 formed in a U-shape in a cross section perpendicular to the longitudinal direction X. The second main body 521 is also called a main body side extension. The second main body 521 is disposed on the second surface 342 side of the base 34. The second main body 521 is a wire protection part for protecting the power supply line 38, and is a fixing part for fixing the holder 50 to the base 34. The holder 50 is attached to the base 34 with the second main body 521, which is a wire protection part, disposed on the second surface 342 side.

When viewed in the direction penetrating the electric wire insertion hole 363, the second body part 521 of the second holder 52 is formed such that the maximum dimension in the direction along the arrangement part 340 is larger than the maximum dimension of the first body part 511 of the first holder 51. Therefore, when the first holder 51 and the second holder 52 are combined, the second body part 521 is arranged outside the first body part 511, and the second body part 521 covers the first body part 511.

When viewed in a direction passing through the electric wire insertion hole 363, the second main body portion 521 of the second holder 52 has the following configuration:
The maximum dimension in the direction along the arrangement portion 340 is larger than the maximum dimension of the electric wire insertion hole 363, which is a through hole. Therefore, when the holder 50a is attached to the base 34, the second main body portion 521 faces the top portion 362 and abuts against the top portion 362. The second main body portion 521 of the holder 50a faces the top portion 362 and abuts against the top portion 362, thereby restricting movement of the holder 50a in the downward direction Z2 in the up-down direction Z, i.e., movement toward the side of the illumination target space.

The second main body 521 is formed in a roughly rectangular shape in a plan view, and as shown in FIG. 24, has a second base 520 formed in a rectangular flat plate shape, and a pair of second side portions 526 rising up from two opposing sides of the second base 520.

The second base 520 has a top surface 527 that forms a wall that is positioned opposite the upper surface 5111 of the first main body 511 when the second holder 52 is attached to the first holder 51, a second guide portion 523 that is a through hole formed in the top surface 527 at a position opposite the first holder 514, and a second holder 524 that protrudes from the top surface 527 toward the top surface 5111.

The top surface portion 527 is formed in a roughly rectangular shape and in a flat plate shape. The second holding portion 524 is a protrusion provided on a portion of the top surface portion 527, and forms a step between the top surface portion 527 and the second holding portion 524. The second holding portion 524 is formed along the end portion of the second base portion 520 on the side opposite to the side where the power supply unit 40 is placed. An engagement claw portion 528 is formed on the inside of the top surface portion 527 so as to protrude toward the upper surface portion 5111 of the first holder 51.

In the second embodiment, an example is shown in which one engaging claw portion 528 is formed on the inside of the top surface portion 527 so as to be engaged with the first holding portion 514 of the first holding device 51. In addition to this, the second holding device 52 may have, for example, two engaging claws formed on the inside of the second side portion 526, and the first holding device 51 may have two engaged claw portions formed on both side surfaces of the first main body portion 511. The engagement between the first holding device 51 and the second holding device 52 may employ a configuration in which two engaging claws and two engaged claw portions are engaged with each other.

The second holding portion 524 is a pressing portion that presses the pair of power supply lines 38 against the first holding device 51 by means of a second restricting portion formed on the second holding device 52 when the first holding device 51 and the second holding device 52 are combined. The second holding portion 524 is also a restricting portion that restricts the movement of the pair of power supply lines 38 by this pressing. The second holding portion 524 holds the power supply lines 38 in the holding device 50a and fixes them to the base 34 so that they do not move.

The second guide portion 523 formed on the second base portion 520 captures the other end 381 of the power supply line 38 so that it faces the side where the power supply unit 40 is arranged when the second holder 52 is attached to the first holder 51. The second guide portion 523 is a guide hole or guide groove that directs the power supply line 38 toward the side of the power supply unit 40.

The power supply unit side edge 5231 on the power supply unit 40 side of the second guide portion 523 is a pressing portion that presses the pair of power supply lines 38 against the first holder 51 by means of a first restricting portion formed on the first holder 51 when the first holder 51 and the second holder 52 are combined. The power supply unit side edge 5231 is a restricting portion that restricts the movement of the pair of power supply lines 38 by pressing the pair of power supply lines 38 together with the first restricting portion. The power supply unit side edge 5231 holds the power supply lines 38 in the holder 50 and fixes them to the base 34 so that they do not move.

The second side portion 526 forms a side wall of the second retainer 52. When the second retainer 52 is attached to the first retainer 51, the second side portion 526 faces the side portion 5112 along the longitudinal direction X of the first main body portion 511 of the first retainer 51. The second side portion 526 is formed along the longitudinal direction X and is formed to extend in the downward Z2 direction in the vertical direction Z from two opposing side edges of the second base portion 520. An engagement flange portion 529 is formed on the end portion of the second side portion 526 opposite the second base portion 520. The engagement flange portion 529 is a protruding portion that extends inward from the end portion of the second side portion 526 opposite the second base portion 520 in a direction along the second base portion 520. The end of the second main body 521, which is an extension on the main body side, on the side where the first base 510 is located, functions as the second engagement portion 525 of the second holder 52.

The two engagement flanges 529 are arranged opposite each other and are formed to protrude toward each other along the short side direction Y. The engagement flanges 529 are formed in a rectangular parallelepiped shape extending in the longitudinal direction X. The engagement flanges 529 engage with the engagement grooves 519, which are grooves formed on both side surfaces in the short side direction Y, of the first connection portion 512 of the first holder 51. The engagement grooves 519 and the engagement flanges 529 engage with each other, thereby fixing the second holder 52 and the first holder 51 to each other. The holder 50a is attached to the base 34 with at least a part of the base 34 being disposed between the first base portion 510 of the first holder 51, which is the holder base, and the second main body portion 521 of the second holder 52.

The second holder 52 is slidably attached so as to cover the first main body 511 of the first holder 51 protruding from the second surface 342 of the base 34. At this time, the engagement groove 519 and the engagement flange 529 engage with each other. When the second holder 52 is attached to the first holder 51, the first holder 51 and the second holder 52 clamp the top 362 of the protruding portion 361 of the holder attachment portion 360 provided on the base 34, and the holder 50a is attached so as to cover the electric wire insertion hole 363 of the base 34. More specifically, when the second holder 52 is attached to the first holder 51, the top 362 of the protruding portion 361 is clamped by the first base 510 of the first holder 51 and the second main body 521 of the second holder 52.

As shown in FIG. 26, the second holder 52 is slid onto the first holder 51, and the engagement groove 519 (first engagement portion 515) of the first holder 51 and the engagement flange 529 (second engagement portion 525) of the second holder 52 engage with each other. The engagement groove 519 (first engagement portion 515) of the first holder 51 and the engagement flange 529 (second engagement portion 525) of the second holder 52 engage with each other, so that the holder 50a does not come off the electric wire insertion hole 363 and is fixed to the base 34.

As described above, the second holder 52 has an engagement claw portion 528 formed to protrude from the top surface portion 527 toward the upper surface portion 5111. As shown in FIG. 27, the engagement claw portion 528 is engaged with the first holder 514 of the first holder 51 when the second holder 52 is slidably attached to the first holder 51 and the first holder 51 and the second holder 52 are combined. In other words, the first holder 514 functions as the first engagement portion 515 of the first holder 51, and the engagement claw portion 528 functions as the second engagement portion 525 of the second holder 52. The engagement claw portion 528 and the first holder 514 restrict the movement of the second holder 52 in the sliding direction relative to the first holder 51, and the second holder 52 is fixed to the first holder 51. The power supply line 38 is held by a first holder 51 and a second holder 52 that are fixed to each other, and is fixed to the base 34 so as not to move.

The holder 50a has the above-mentioned configuration, and the first insertion portion 5131 through which the power supply line 38 is inserted is formed, and has a restricting portion consisting of the first holding portion 514 and the second holding portion 524 for restricting the movement of the power supply line 38 arranged in the first insertion portion 5131. The first holding portion 514 and the second holding portion 524 of the holder 50a restrict the movement of the power supply line 38 by pressing the power supply line 38 from both sides. The holder 50a is inserted into the electric wire insertion hole 363, which is a through hole provided in the base 34, and is attached to the base 34 in a state in which the movement toward the second surface 342 of the base 34 is restricted. In other words, the holder 50a is restricted from moving toward the second surface 342 when attached to the electric wire insertion hole 363, which is a through hole.

In this manner, when the second body part 521 is attached to the first body part 511, at least a portion of the edge of the electric wire insertion hole 363 formed in the top 362 of the protrusion 361 is positioned between the first base part 510 and the second body part 521, so that the movement of the holder 50a in the direction penetrating the electric wire insertion hole 363 is restricted and the holder 50a is attached to the positioning part 340.

The holder 50a has a guide section consisting of a first guide section 513 in which a first insertion section 5131 is formed and a second guide section 523 which is a guide hole, and a restricting section consisting of a first main body section 511 in which a first holding section is formed and a second main body section 521 in which a second holding section 524 is formed. The power supply line 38 is guided by the first guide section 513 and the second guide section 523. The power supply line 38 is inserted into the first insertion section 5131 of the first guide section 513, and the second main body section 521 is attached to the first main body section 511, so that the movement of the power supply line 38 is restricted. Furthermore, the power supply line 38 is pressed from both sides by the first holding section 514 and the second holding section 524, so that the power supply line 38 can be prevented from falling off the holder 50a. As shown in FIG. 24, the first holding portion 514 of the first holder 51 and the second holding portion 524 of the second holder 52 are disposed at opposing positions with the power supply line 38 therebetween. The power supply line 38 is guided so as to connect the first surface 341 side and the second surface 342 side by a guide portion consisting of a first guide portion 513 in which a first insertion portion 5131 is formed and a second guide portion 523 which is a guide hole.

Figure 33 is a cross-sectional view of the first holder 51 and base 34 in the lighting fixture 3 along the longitudinal direction X. Figure 34 is a cross-sectional view of the power supply line 38 arranged on the first holder 51 in Figure 33. Figure 35 is a cross-sectional view of the power supply line 38 in Figure 34 bent. Figure 36 is a cross-sectional view of the second holder 52 attached to the first holder 51. The details of the holding of the power supply line 38 by the holder 50a will be further described using Figures 33 to 36.

As shown in FIG. 33, the first holder 51 is attached to the holder attachment portion 360 so that the first base portion 510 fits into a recess (concave portion) on the first surface 341 side of the protrusion 361 formed on the base 34.

As shown in FIG. 34, the power supply line 38, from which the exterior 383 on the one end 380 side has been removed in advance, is inserted into the first insertion portion 5131 of the first holder 51 from the second surface 342 side of the base 34 toward the first surface 341 side, with the conductor 382 exposed. The board 32 may be fixed to the base 34 first, in which case the one end 380 of the power supply line 38 is inserted into the first insertion portion 5131 of the first holder 51 and the board through hole 322 from the second surface 342 side of the base 34 toward the one surface 320 side of the board 32.

35, the power supply line 38 is bent toward the power supply unit 40 near the end 5132 of the first insertion portion 5131 opposite the first base 510. Since the power supply line 38 is bent toward the direction intersecting with the direction (Z) in which the power supply line 38 is inserted into the first insertion portion 5131, the one end 380 does not come off the first insertion portion 5131 even if it receives tension along the direction intersecting with the direction (Z) in which the power supply line 38 is inserted into the first insertion portion 5131. Also, since the power supply line 38 is bent toward the direction intersecting with the direction (Z) in which the power supply line 38 is inserted into the first insertion portion 5131, the other end 381 does not come off the first insertion portion 5131 even if it receives tension along the direction (Z) in which the power supply line 38 is inserted into the first insertion portion 5131. In this way, the end 5132 of the first insertion portion 5131 opposite the first base portion 510 functions as a restricting portion (first restricting portion) that restricts the movement of the power supply line 38.

When the second holder 52 is slidably attached to the first holder 51, the wiring path (location) of the power supply line 38 is determined by the first guide portion 513, that is, the first insertion portion 5131 and the second guide portion 523. The power supply line 38 is held by the end portion 5132 (first restriction portion) on the side opposite to the first base portion 510 of the first insertion portion 5131 and the second holding portion 524 (second restriction portion) to restrict movement. The power supply line 38 is held by the second holding portion 524 (second restriction portion) and the first holding portion 514 (first restriction portion) to restrict movement. Furthermore, the power supply line 38 is held by the first holding portion 514 (first restriction portion) and the power supply unit side edge portion 5231 (second restriction portion) on the side of the power supply unit 40 in the second guide portion 523 to restrict movement. By attaching the second holder 52 to the first holder 51, the holder 50a is fixed to the base 34. With the restricting portion fixed to the base 34, the movement of the power supply line 38 from the base 34 is restricted.

(Holder fixing part 56a)
Next, the holder fixing portion 56a will be described with reference to FIG. 24. As described above, the second body portion 521 of the second holder 52 is positioned at the position where the second body portion 521 is located, when viewed in the direction passing through the electric wire insertion hole 363. 1. The maximum dimension of the first holder 51 in the direction along the wire insertion hole 363 is larger than the maximum dimension of the wire insertion hole 363 which is a through hole. Therefore, when the second holder 52 is attached to the first holder 51, the holding The holder 50a is fixed to the base 34. That is, in the holder 50a of the second embodiment, the second holding portion 524 functions as a holder fixing portion 56a.

In detail, as shown in Figures 26 and 27, the holder fixing portion 56a is composed of an engagement flange portion 529 (second engagement portion 525) of the second main body portion 521 of the second holder 52, a first protrusion portion 530 of the engagement flange portion 529 that protrudes further in the longitudinal direction X than the first main body portion 511, and a second protrusion portion 531 of the second side portion 526 that protrudes further in the longitudinal direction X toward the power supply unit 40 than the engagement claw portion 528.

When the second holder 52 is attached to the first holder 51, the first protrusion 530 overlaps with the edge of the apex 362 that forms the electric wire insertion hole 363 along the direction of passing through the electric wire insertion hole 363. In other words, at least a portion of the apex 362, which is the edge of the electric wire insertion hole 363, is disposed between the first base and the first protrusion 530, and the holder 50a is fixed to the arrangement portion 340 of the base 34 with its movement restricted along the direction of passing through the electric wire insertion hole 363.

When the power supply unit 40 is fixed to the base 34, the second protrusion 531 overlaps with the end of the power supply case 42 in the longitudinal direction X along the direction passing through the electric wire insertion hole 363. In other words, at least a part of the power supply case 42 fixed to the base 34 is disposed between the second protrusion 531 and the top 362, and the holder 50a is restricted from moving along the direction passing through the electric wire insertion hole 363 and is fixed to the arrangement part 340 of the base 34. As shown in Figures 27 to 29 and 37, the second protrusion 531 protrudes by L3 from the end of the first protrusion 530 on the side of the power supply unit 40 toward the power supply unit 40.

(Power supply holding part 556)
Next, the power supply holding unit 516 will be described with reference to Fig. 37 and Fig. 38. Fig. 37 shows the state before the power supply unit 40 is held by the holder 50a, and Fig. 38 shows the state after the power supply unit 40 is held by the holder 50a. 5 shows the state in which it is held by fixture 50a.

As shown in FIG. 37, the holder connection part of the holder 50a is provided with a power supply holding part 5510. As shown in FIG. 37, the power supply holding part 516 is a recess or a through hole formed in the first holder 51 of the holder 50a. At least a part of the power supply unit 40 is inserted into the power supply holding part 516, and the power supply unit 40 holds the part. As shown in FIG. 37, the power supply unit 40 is provided with an insertion piece 420 at the end of the power supply case 42 on the holder 50 side. The power supply holding part 516 has a complementary shape to the insertion piece 420. The power supply holding part 516 functions as an insertion piece insertion hole into which the insertion piece 420 is inserted. When the power supply unit 40 is attached to the base 34, the insertion piece 420 of the power supply unit 40 is inserted into the power supply holding part 516 of the holder 50a.

Furthermore, as described in the first embodiment, the base 34 is provided with a screw insertion hole 354 and a power supply fixing portion 356 as shown in FIG. 4. Furthermore, the power supply case 42 is provided with a screw insertion hole 421 as shown in FIGS. 4 and 5. As shown in FIGS. 4 and 5, a fastener 85 such as a screw is inserted into the screw insertion hole 354 and the screw insertion hole 421 to fasten them. The power supply case 42 is fixed to the base 34 by both the power supply holding portion 5110 and the fastener 85.

In this way, the plug-in piece 420, which is part of the power supply unit 40, is held by the power supply holding portion 5110 of the holder 50a. Furthermore, the remaining parts of the power supply unit 40, excluding the part in question, are fixed to the base 34 by the fixing device 85. In this way, by fixing the remaining parts of the power supply unit 40 to the base 34 with the fixing device 85, the state in which the plug-in piece 420, which is part of the power supply unit 40, is held by the holder 50a is maintained. Furthermore, the holder 50a is fixed to the base 34 with the power supply unit 40 attached to the base 34. This restricts movement of the power supply unit 40.

(Procedure for holding and connecting the power supply line 38)
The procedure for holding and connecting the power supply line 38 will be described with reference to FIGS.

(Step 1)
24 , the base 34 is formed with a holder attachment portion 360. The holder attachment portion 360 includes an electric wire insertion hole 363. The holder 50a is attached so as not to protrude from the first surface 341 side of the base 34. Therefore, the portion of the base 34 to which the holder 50a is attached is provided with a protruding portion 361 that protrudes from the second surface 342 side by drawing or the like, and the electric wire insertion hole 363 is provided at a top 362 of the protruding portion 361.

(Step 2)
The first holder 51 is attached to the first surface 341 side of the base 34 in the direction indicated by the arrow in Fig. 25. Note that the power supply line 38 is not shown in Fig. 25. The first holder 51 is attached to the holder attachment part 360 so that the first base part 510 fits into a recess (concave part) on the first surface 341 side of the protrusion 361 formed on the base 34. In this state, the first main body part 511 which is a part of the first holder 51 passes through the electric wire insertion hole 363 and protrudes to the second surface 342 side of the base 34.

The maximum dimension of the first base 510 is formed to be larger than the maximum dimension of the electric wire insertion hole 363, so that the first base 510 does not pass through the electric wire insertion hole 363. In other words, the first holder 51 remains on the side of the first surface 341 of the base 34 by the first base 510 being caught on the edge of the top 362 that forms the electric wire insertion hole 363, and movement toward the second surface 342 is restricted.

(Step 3)
The substrate 32 is adhesively fixed to the first surface 341 of the base 34 using an adhesive member 87 (see FIG. 12 ) such as an adhesive. At this time, the position of the substrate 32 is determined so that a first insertion portion 5131, which is a through hole provided in the first guide portion 513 of the first holder 51, overlaps with a substrate through hole 322 provided in the substrate 32 in the direction penetrating the electric wire insertion hole 363, as shown in FIG. 24 . Note that the substrate 32 and the base 34 may be fixed to each other using an adhesive sheet, screws, rivets, or the like instead of an adhesive.

The first base 510 of the first holder 51 is formed to fit into the recessed portion (concave portion) on the side of the first surface 341 of the protrusion 361, and does not interfere with adhesively fixing the substrate 32 to the base 34. In this state, the first base 510, which is the holder base, is disposed between the base 34 and the substrate 32 of the light source unit 31. Then, by adhesively fixing the substrate 32 to the base 34, the first holder 51 is covered by the substrate 32 in the direction in which the first holder 51 is removed from the base 34, and therefore the first holder 51 does not fall off the base 34.

(Step 4)
With the exterior 383 on the side of one end 380 of the power feeder 38 removed to expose the conductor 382, the one end 380 is inserted from the second surface 342 side of the base 34 through the first insertion portion 5131 of the first holder 51 and the board through hole 322 of the board 32. That is, the one end 380 of the power feeder 38 passes through the first insertion portion 5131 of the first holder 51 and the board through hole 322 of the board 32. The power feeder 38 is inserted through the board through hole 322 such that the conductor 382 of the one end 380 is exposed on the side of the one surface 320 of the board 32.

At this time, the power supply line 38 passes through the electric wire insertion hole 363 of the base 34 while being disposed in the first holder 51. Since the first holder 51 is present between the power supply line 38 and the edge of the base 34 that forms the electric wire insertion hole 363, the power supply line 38 does not come into contact with the edge of the base 34 that forms the electric wire insertion hole 363. In other words, the holder 50a is attached to the base 34 so that the power supply line 38 does not come into contact with the edge of the electric wire insertion hole 363, which is a through hole. In other words, the holder 50a is attached to the base 34 so that the power supply line 38 does not come into contact with the edge of the electric wire insertion hole 363, which is a through hole.

In the second embodiment, one end 380 of the power supply line 38 is configured to connect the exposed conductor 382 to the power receiving section 324 of the substrate 32. Note that the connection between the power supply line 38 and the power receiving section 324 is not limited to this configuration. For example, the lighting device 3 may be configured such that a connection part such as a terminal or connector is attached to the one end 380 in advance, and the mounting part such as a terminal or connector mounted on the substrate 32 is connected to the connection part.

In the second embodiment, one end 380 of the power supply line 38 is configured to pass through the substrate 32. Note that the relationship between the power supply line 38 and the substrate 32 is not limited to this configuration. For example, one end 380 of the power supply line 38 may be arranged along a path that does not pass through the substrate 32.

(Step 5)
While keeping the conductor 382 of the power supply line 38 exposed on the side of the first surface 320 of the substrate 32, the second holder 52 is slidably attached to the first body portion 511 of the first holder 51 as shown by the arrow B in Fig. 30, to obtain the state shown in Fig. 31. In this state, the holder 50a is fixed to the base 34 while holding the power supply line 38.

The first body 511 and the second holder 52 of the first holder 51 are provided with an engagement mechanism for engaging with each other. This engagement mechanism is a first engagement portion 515 formed on the first body 511 as shown in FIG. 25, and a second engagement portion 525 formed on the second holder 52 as shown in FIG. 24. The first engagement portion 515 is formed in a groove shape, and the second engagement portion 525 is formed in a protrusion shape. When the second holder 52 is slidably attached to the first holder 51, the second engagement portion 525 formed in a protrusion shape is guided by the first engagement portion 515 formed in a groove shape. This allows the second holder 52 to be attached to the first holder 51 in the correct position.

The second holder 52 is formed so that its maximum dimension is greater than the maximum dimension of the electric wire insertion hole 363, so that the second holder 52 does not pass through the electric wire insertion hole 363. In other words, when the second holder 52 is attached to the first body portion 511 of the first holder 51, it is hooked on the edge of the electric wire insertion hole 363, so that it remains on the side of the second surface 342 of the base 34, and movement toward the first surface 341 is restricted.

By attaching the second holder 52 to the first body portion 511 of the first holder 51, the holder 50a maintains its attachment to the base 34 even if the substrate 32 is not adhesively fixed to the first surface 341 of the base 34.

(Step 6)
32 , the conductor 382 on the side of the other end 381 of the power supply line 38 is gently bent downward Z2 in the up-down direction Z. Thereafter, the conductor 382 is inserted into the output terminal 41 of the power supply unit 40, and the power supply line 38 is connected to the power supply unit 40. Note that the connection between the conductor 382 and the output terminal 41 is not limited to the mode in which the conductor 382 is inserted into the output terminal 41.

(Step 7)
13 , on the side of the one surface 320 of the substrate 32, a conductor 382 on the side of one end 380 of the power feed line 38 is exposed from the one surface 320 of the substrate 32. The tip of the exposed conductor 382 is bent toward the power receiving unit 324 so as to approach the power receiving unit 324.

Procedure 7 is a procedure performed to protect the holder 50a or the power supply line 38 when a laser is used to connect the conductor 382 and the power receiving unit 324 by soldering or welding. Procedure 7 is a device for performing the connection at a position away from the board through hole 322 so that the laser does not pass through the board through hole 322 and damage the holder 50a arranged on the other side 321 of the board 32 or the exterior 383 of the power supply line 38.

(Step 8)
24, a conductor 382 on one end 380 of the power supply line 38 is connected to the power receiving unit 324 using a connecting member such as solder (not shown). Note that the connection between the conductor 382 and the power receiving unit 324 can be made by using an anisotropic conductive member or by welding, in addition to solder.

As shown in steps 7 and 8, in the second embodiment, one end 380 of the power supply line 38 is configured to be connected to the power receiving unit 324 on the side of one surface 320 of the substrate 32. Note that the connection between the one end 380 of the power supply line 38 and the power receiving unit 324 is not limited to this configuration. For example, the one end 380 of the power supply line 38 may be connected to the power receiving unit 324 on the side of the other surface 321 of the substrate 32.

The lighting fixture 3 is fixed to the base 34 in step 5 with the power supply line 38 held by the holder 50a, so even if step 6 is performed after steps 7 and 8 are completed, no stress is applied to the connection between the power supply line 38 and the power receiving part 324.

In addition, once step 5 has been completed, the assembly work for the lamp 3 can be performed without restricting the order of steps 6, 7, and 8.

In the above-mentioned first embodiment, the description of the method of connecting the power supply line 38 to the power supply unit 40 and the method of connecting the power supply line 38 to the power receiving unit 324 is omitted. However, in the first embodiment, the same processes as steps 6 to 8 in the second embodiment may be performed to connect the power supply line 38 to the power supply unit 40 and the power supply line 38 to the power receiving unit 324.

In both the first and second embodiments, the holders 50 and 50a are fixed to the base 34 with the power supply unit 40 attached to the base 34. However, this is not limited to the above case, and the power supply unit 40 may be fixed to the base 34 with the holders 50 and 50a attached to the base 34. That is, the holders 50 and 50a may be attached after the power supply unit 40 or the power supply case 42 is attached to the base 34. Alternatively, conversely, the power supply unit 40 or the power supply case 42 may be attached to the base 34 after the holders 50 and 50a are attached.

(Procedure for holding the power supply unit 40)
The procedure for holding the power supply unit 40 according to the second embodiment will be described with reference to FIGS.

(Step 1)
As shown in Fig. 37, the plug-in piece 420 provided on the power supply case 42 of the power supply unit 40 is moved in the direction of arrow C and inserted into the power supply holding part 5110 of the holder 50a. As a result, the power supply case 42 of the power supply unit 40 and the holder 50a are connected to each other as shown in Fig. 38.

(Step 2)
Next, with the power supply case 42 of the power supply unit 40 and the retaining device 50a connected, as shown in Figures 4 and 5, a fastener 85 such as a screw is inserted into the screw insertion hole 354 of the power supply fixing part 356 and then inserted into the screw insertion hole 421 of the power supply case 42 to fasten them together.

31 and 32, the above steps 1 and 2 may be performed in a state where the power supply device 44 and the power supply cover 43 of the power supply unit 40 are attached to the power supply case 42 in advance. However, this is not limited to the above, and as shown in Figs. 37 and 38, the above steps 1 and 2 may be performed in a state where the power supply device 44 and the power supply cover 43 of the power supply unit 40 are not attached to the power supply case 42. In this case, after steps 1 and 2 are completed, the power supply device 44 and the power supply cover 43 of the power supply unit 40 are attached to the power supply case 42. Although not shown in the drawings, the above steps 1 and 2 may be performed in a state where only the power supply cover 43 of the power supply unit 40 is not attached to the power supply case 42. In this case, after steps 1 and 2 are completed, the power supply cover 43 of the power supply unit 40 is attached to the power supply case 42.

As shown in Figures 37 and 38, in the second embodiment, when the power supply unit 40 is connected to the holder 50a, a portion of the power supply case 42 other than the insertion piece 420 and the second protruding portion 531 of the holder 50a overlap by a dimension L3 along the longitudinal direction X.

[Functions and Effects of the Lighting Fixture 3 and the Lighting Device 1]
The lamp 3 includes a holder 50a. The holder 50a is formed with a first insertion portion 5131 through which the power supply line 38 is inserted, and has a restricting portion consisting of a first holding portion 514 and a second holding portion 524 for restricting movement of the power supply line 38 arranged in the first insertion portion 5131. The holder 50a is inserted into the electric wire insertion hole 363, which is a through hole, and is attached to the base 34 in a state in which movement toward the second surface 342 of the base 34 is restricted.

By having the holder 50a of the above configuration, the lighting fixture 3 can hold the power supply line 38 without applying stress to the connection between the power supply line 38 and the substrate 32, even if the power supply line 38 is pulled during assembly of the lighting fixture 3 or installation of the lighting device 1. Therefore, even if the power supply line 38 is pulled during assembly of the lighting fixture 3 or installation of the lighting device 1, the lighting fixture 3 can prevent damage to the power supply line 38 or components such as the power supply unit 40 that is arranged on the second surface 342 side and connected to the power supply line 38. Furthermore, the lighting fixture 3 can prevent the power supply line 38 from coming off the power supply unit 40, and can prevent the power supply line 38 from breaking.

In addition, by having the retainer 50a of the above configuration, the lighting fixture 3 can prevent damage to the exterior 383 of the power supply line 38 caused by the edge of the wire insertion hole 363, and can prevent a short circuit between the conductor 382 of the power supply line 38 and the edge of the wire insertion hole 363. In addition, by having the retainer 50a of the above configuration, the insulation performance between the exposed portion of the conductor 382 of the power supply line 38 and the base 34 can be ensured.

In addition, the power supply line 38 is held by the holder 50a configured as described above and fixed to the base 34, so that no stress is applied to the connection between the power supply line 38 and the power receiving part 324 when assembling the lamp 3 and when installing the lighting device 1.

The power supply line 38 is attached to the holder 50a so as not to come into contact with the edge of the wire insertion hole 363, which is a through hole. Therefore, the lighting device 3 can prevent damage to the exterior 383 of the power supply line 38 caused by the edge of the wire insertion hole 363, and a short circuit between the conductor 382 of the power supply line 38 and the edge of the wire insertion hole 363. Furthermore, by having the holder 50a configured as described above, the insulation performance between the exposed portion of the conductor 382 of the power supply line 38 and the base 34 can be ensured.

The holder 50a is attached to the base 34 so as to cover the electric wire insertion hole 363, which is a through hole. Therefore, the lighting device 3 can prevent damage to the exterior 383 of the power supply line 38 caused by the edge of the electric wire insertion hole 363, and a short circuit between the conductor 382 of the power supply line 38 and the edge of the electric wire insertion hole 363. Furthermore, by having the holder 50a configured as described above, the insulation performance between the exposed portion of the conductor 382 of the power supply line 38 and the base 34 can be ensured.

The maximum dimension of the first base 510, which is the holder base, is larger than the maximum dimension of the electric wire insertion hole 363, and the maximum dimension of the second body 521, which is the holder main body, is larger than the maximum dimension of the electric wire insertion hole 363. The maximum dimension of the first body 511, which is the holder connection part, is smaller than the maximum dimension of the second body 521, which is the holder main body. Therefore, the second holder 52 does not pass through the electric wire insertion hole 363. That is, when the second holder 52 is attached to the first body 511 of the first holder 51, it is hooked on the edge of the electric wire insertion hole 363, so that it remains on the side of the second surface 342 of the base 34, and its movement toward the first surface 341 is restricted. In addition, the holder 50a is attached so that the base 34 is clamped between the first holder 51 and the second holder 52, and the holder 50a closes the electric wire insertion hole 363 of the base 34.

The length dimension of the first body 511, which is the holder connection part, in the direction of penetrating the electric wire insertion hole 363 is formed to be larger than the thickness dimension of the base 34. With this configuration, the lighting fixture 3 can arrange the first body 511 between the edge of the electric wire insertion hole 363 and the exterior 383 of the power supply line 38. As a result, the lighting fixture 3 can prevent damage to the exterior 383 of the power supply line 38 caused by the edge of the electric wire insertion hole 363, and a short circuit between the conductor 382 of the power supply line 38 and the edge of the electric wire insertion hole 363. In addition, by having the holder 50a of the above configuration, the insulation performance between the exposed portion of the conductor 382 of the power supply line 38 and the base 34 can be ensured.

The holder 50a is attached to the base 34 with at least a portion of the base 34 disposed between the first base 510, which is the holder base, and the second engagement portion 525. Therefore, even if the power supply line 38 is pulled during assembly or installation of the lighting device 1, the lighting fixture 3 can prevent damage to components such as the power supply line 38 or the power supply unit 40 disposed on the second surface 342 side and connected to the power supply line 38. The lighting fixture 3 can also prevent the power supply line 38 from coming off the power supply unit 40, and can prevent the power supply line 38 from breaking.

The first base 510, which is the holder base, is disposed between the base 34 and the light source unit 31. In the direction in which the first holder 51 is removed from the base 34, the holder 50a can prevent the first holder 51 from falling off the base 34 because the first base 510 is covered by the light source unit 31.

In addition, the movement of the power supply line 38 is restricted by attaching the second main body portion 521, which is a fixed portion, to the first guide portion 513 while the power supply line 38 is inserted into the first insertion portion 5131 of the first guide portion 513. Therefore, even if the power supply line 38 is pulled during assembly or during installation of the lighting device 1, the lighting fixture 3 can prevent damage to the power supply line 38 or components such as the power supply unit 40 arranged on the second surface 342 side and connected to the power supply line 38. In addition, the lighting fixture 3 can prevent the power supply line 38 from coming off the power supply unit 40, and can prevent the power supply line 38 from being disconnected.

In addition, the first guide portion 513 and the second main body portion 521, which is the fixed portion, are arranged adjacent to each other in a direction along the direction of passing through the electric wire insertion hole 363, which is a through hole, when the holder 50a is attached to the base 34. Therefore, the holder 50a can slide the second holder 52 to the first holder 51. Furthermore, the holder 50a can wire the power supply line 38 toward the power supply unit 40 due to the above configuration. With the above configuration, even if the power supply line 38 is pulled during assembly or during construction of the lighting device 1, the lighting device 3 can prevent damage to the power supply line 38 or the power supply unit 40 arranged on the second surface 342 side and connected to the power supply line 38. Furthermore, the lighting device 3 can prevent the power supply line 38 from coming off the power supply unit 40, and can prevent the power supply line 38 from being disconnected.

In addition, in the lighting device 1, when the lamp 3 is attached to the fixture 2, a power supply unit 40 that supplies power to the light source unit 31 is disposed between the second surface 342 of the base 34 and the fixture 2, and the other end 381 of the power supply line 38 is electrically connected to the power supply unit 40. Since the lighting device 1 has a holder 50a, even if the power supply line 38 is pulled during assembly or during construction of the lighting device 1, damage to the power supply line 38 or the power supply unit 40 disposed on the second surface 342 side and connected to the power supply line 38 can be prevented. In addition, the lighting device 1 can prevent the power supply line 38 from coming off the power supply unit 40, and can prevent the power supply line 38 from being disconnected.

The holder 50a also has a power supply holding part 5110 that holds a part of the power supply unit 40. With the holder 50a attached to the base 34, a part of the power supply unit 40 is inserted into the power supply holding part 5110, so that the power supply unit 40 is held on the base 34. The other part of the power supply unit 40 is attached to the base 34 with a fastener 85 such as a screw. In this way, by fixing the other part of the power supply unit 40 with the fastener 85, the holding state between the part of the power supply unit 40 and the holder 50a is maintained. In addition, by holding a part of the power supply unit 40 with the holder 50a, the posture of the power supply unit 40 is easily maintained, so that the fastener 85 can be prevented from loosening due to aging. In this way, the synergistic effect of the power supply holding part 556 and the fastener 85 allows the power supply unit 40 to be stably fixed to the base 34.

The part of the power supply unit 40 is the plug-in piece 420 provided in the power supply case 42, and the power supply holding portion 556 is a plug-in piece insertion hole into which the plug-in piece 420 is inserted. Therefore, the work is easy because the plug-in piece 420 only needs to be inserted into the power supply holding portion 5110.
