DETAILED DESCRIPTION OF THE INVENTION

[0013] Hereinafter, an embodiment of a lighting fixture of the present invention will be described with reference to the drawings (FIGS. 1 to 19). However, the present invention is not limited to the following embodiment, and can be implemented in various forms without departing from the gist of the present invention. Note that where explanations are redundant, they may be omitted as appropriate. Furthermore, in the drawings, identical or equivalent parts are designated by the same reference symbols, and explanations will not be repeated.

[0014] In this specification, to facilitate understanding of the invention, the description may refer to the X, Y, and Z directions which are orthogonal to each other. For example, the X and Y directions are parallel to the horizontal direction, and the Z direction is parallel to the vertical direction. However, the X and Y directions may be parallel to a direction other than the horizontal direction, and the Z direction may be parallel to a direction other than the vertical direction.

[0015] [Embodiment 1] A first embodiment of the present invention will be described below with reference to Figs. 1 to 17. First, a lighting fixture 100 of this embodiment will be described with reference to Fig. 1. Fig. 1 is a side view showing the lighting fixture 100 of this embodiment. As shown in Fig. 1, the lighting fixture 100 includes a housing 2, a cover member 4, and a feed wiring 31.

[0016] The housing 2 is an elongated member extending in the X direction (a fixed direction). Hereinafter, the direction in which the housing 2 extends may be referred to as the "longitudinal direction X." The cover member 4 is disposed on the -Z side of the housing 2. In other words, the cover member 4 protrudes from the housing 2 on the -Z side. The cover member 4 is an elongated member extending in the longitudinal direction X. The cover member 4 is, for example, a shade or a diffusion cover.

[0017] The feed wiring 31 is drawn from the inside to the outside of the housing 2. Specifically, the feed wiring 31 is drawn from the end of the housing 2 on the −X side (one end in the longitudinal direction X).

[0018] The outgoing wiring 31 includes a power line. The power line includes a power line (core wire) with a positive (+) polarity and a power line (core wire) with a negative (-) polarity. The power line of the outgoing wiring 31 transmits power (external power) to another lighting fixture 100 connected to the lighting fixture 100 shown in FIG. 1. For example, the power line of the outgoing wiring 31 transmits AC power (external power) from a commercial power source.

[0019] The feed wiring 31 may further include a ground wire (core wire). The feed wiring 31 may further include a signal wire. The signal wire includes a signal wire (core wire) with a positive (+) polarity and a signal wire (core wire) with a negative (-) polarity. The signal wire of the feed wiring 31 transmits a control signal for controlling another lighting device 100. For example, if the lighting device 100 is controlled using the Digital Addressable Lighting Interface (DALI) control method, the signal wire transmits a DALI signal. If the lighting device 100 is controlled using the Pulse Width Modulation (PWM) control method, the signal wire transmits a PWM signal.

[0020] Next, the lighting fixture 100 will be further described with reference to Fig. 2. Fig. 2 is an exploded perspective view of the lighting fixture 100 of the present embodiment. Note that in Fig. 2, the feed wiring 31 shown in Fig. 1 is omitted for simplicity of the drawing.

[0021] As shown in FIG. 2, the housing 2 has, for example, an angular, generally U-shaped cross section. In other words, the housing 2 is a hollow rectangular parallelepiped, with a surface 2c on the -Z side being open. In this embodiment, the housing 2 also has an end surface 2a on the +X side (one side in the longitudinal direction X) and an end surface 2b on the -X side (the other side in the longitudinal direction X) being open. The housing 2 is, for example, an integrally molded product. The housing 2 is made of a metal such as aluminum. The housing 2 may also be an extrusion molded product made of metal. Using a metal material for the housing 2 improves the heat dissipation of the lighting device 100.

[0022] The housing 2 (lighting fixture 100) is attached to a mounting surface such as a ceiling surface, a wall surface (side wall), or a floor surface. The ceiling surface may be parallel to the horizontal direction or may be inclined relative to the horizontal direction. When the housing 2 (lighting fixture 100) is attached to a ceiling surface parallel to the horizontal direction, the +Z side is the upper side and the -Z side is the lower side. The housing 2 (lighting fixture 100) may be attached directly to the ceiling surface or may be suspended from the ceiling surface.

[0023] 2, the lighting device 100 further includes a light-emitting module 6, a base member 8, a power supply unit 10, two mounting members 12, a first end member 14a, and a second end member 14b. The housing 2 accommodates the power supply unit 10, the two mounting members 12, the base member 8, and the light-emitting module 6.

[0024] The light-emitting module 6 is an elongated member extending in the longitudinal direction X. The light-emitting module 6 is disposed on the -Z side of the base member 8. The light-emitting module 6 emits light. The light-emitting module 6 is an example of a light source unit. More specifically, the light-emitting module 6 faces the inner surface of the cover member 4 and emits light toward the inner surface of the cover member 4. As a result, the light passes through the cover member 4 and is emitted to the outside of the lighting device 100.

[0025] Specifically, the light-emitting module 6 has a plurality of light-emitting elements 61 and a substrate 62. The plurality of light-emitting elements 61 are mounted on the substrate 62. The plurality of light-emitting elements 61 face the inner surface of the cover member 4. Each of the light-emitting elements 61 is, for example, an LED (Light Emitting Diode). Alternatively, each of the light-emitting elements 61 may be an organic EL (Electro-Luminescence) element or a laser diode.

[0026] The light emitting module 6 may have, for example, a COB (Chip on Board) structure. Specifically, the light emitting module 6 may have a structure in which a plurality of light emitting elements 61 are mounted on a mounting surface of a substrate 62 and sealed with a phosphor. Alternatively, the light emitting module 6 may have an SMD (Surface Mount Device) structure. Specifically, the light emitting module 6 may have a structure in which a plurality of units, each of which integrates a single light emitting element 61 and a phosphor, are electrically connected to a conductor on the substrate 62.

[0027] The plurality of light-emitting elements 61 are arranged in a line along the longitudinal direction X. However, the arrangement of the plurality of light-emitting elements 61 is not limited to a single line. The plurality of light-emitting elements 61 may be arranged in two or more lines along the longitudinal direction X, or may be arranged in a staggered pattern.

[0028] In this embodiment, the light emitting module 6 includes a first light emitting module 6a and a second light emitting module 6b. The first light emitting module 6a and the second light emitting module 6b face each other in the X direction. In other words, the first light emitting module 6a and the second light emitting module 6b are arranged side by side along the longitudinal direction X. The lighting device 100 may include one light emitting module 6. Alternatively, the lighting device 100 may include three or more light emitting modules 6 arranged along the longitudinal direction X.

[0029] The cover member 4 is disposed on the -Z side of the base member 8 and covers the light-emitting module 6 from the -Z side. The cover member 4 is hollow and has an open surface on the +Z side. In this embodiment, the cover member 4 also has an open end surface 4a on the +X side (one side in the longitudinal direction X) and an open end surface (not shown) on the -X side (the other side in the longitudinal direction X).

[0030] The cover member 4, for example, diffuses the light emitted by the light-emitting module 6. The cover member 4 may be, for example, white and translucent. The cover member 4 may be formed, for example, by molding a resin containing a light-diffusing material, or by molding a transparent material and then subjecting the surface to a light-diffusing treatment.

[0031] The base member 8 is an elongated member extending in the longitudinal direction X. The base member 8 is, for example, an integrally molded product. The material of the base member 8 is, for example, a metal such as aluminum. The base member 8 may also be an extrusion molded product made of metal. When the base member 8 is made of metal, the base member 8 functions as a heat sink for the light-emitting module 6.

[0032] The light emitting module 6 and the cover member 4 are attached to the base member 8. In other words, the base member 8 supports the light emitting module 6 and the cover member 4. Specifically, the base member 8 has a main surface 8a on the -Z side. The light emitting module 6 and the cover member 4 are supported on the main surface 8a side of the base member 8.

[0033] The power supply unit 10 is an elongated member extending along the longitudinal direction X. The power supply unit 10 has, for example, a substantially rectangular parallelepiped shape. The power supply unit 10 is arranged on the +Z side of the base member 8. The power supply unit 10 is attached to the base member 8. In other words, the base member 8 supports the power supply unit 10. More specifically, the base member 8 has a main surface 8b (see FIG. 11) on the +Z side. The power supply unit 10 is supported on the main surface 8b side of the base member 8. Therefore, the base member 8 is arranged between the power supply unit 10 and the light-emitting module 6. In other words, the power supply unit 10 and the light-emitting module 6 face each other with the base member 8 in between.

[0034] The power supply unit 10 may be fixed to the base member 8 by a fastening member such as a screw. If the base member 8 is made of metal, the base member 8 functions as a heat sink for the power supply unit 10.

[0035] The power supply unit 10 generates power to drive the light-emitting module 6. In other words, the power supply unit 10 generates power to cause the plurality of light-emitting elements 61 to emit light. Hereinafter, the power generated by the power supply unit 10 may be referred to as "internal power." The internal power is supplied to the light-emitting module 6 via the secondary-side output line 33 (see FIG. 10). For example, if the light-emitting elements 61 are LEDs, the power supply unit 10 generates a direct current.

[0036] Specifically, the power supply unit 10 includes a power supply circuit. The power supply circuit is configured with a wiring board and electronic components mounted on the wiring board. The power supply circuit generates internal power based on external power, for example, from a commercial power source.

[0037] The power supply unit 10 may further include a control circuit that controls the power supply circuit. The control circuit is mounted on a wiring board. For example, if the control method of the lighting device 100 is the DALI control method, the control circuit controls the power supply circuit based on the DALI signal. If the control method of the lighting device 100 is the PWM control method, the control circuit controls the power supply circuit based on the PWM signal. The control circuit includes, for example, a microcomputer.

[0038] The two mounting members 12 are arranged on the +Z side of the base member 8. The two mounting members 12 are aligned in a row along the longitudinal direction X. Specifically, the two mounting members 12 face each other with the power supply unit 10 in between. In other words, the power supply unit 10 is arranged between the two mounting members 12.

[0039] The two mounting members 12 are attached to the base member 8. In other words, the base member 8 supports the two mounting members 12. For example, each of the mounting members 12 may be fixed to the base member 8 by a fastening member such as a screw.

[0040] Each of the mounting members 12 has elasticity. The elasticity of each of the mounting members 12 allows it to fit inside the housing 2. The base member 8 is attached to the housing 2 by fitting each of the mounting members 12 inside the housing 2.

[0041] The first end member 14a closes the opening in the end surface 2a of the housing 2 and the opening in the end surface 4a of the cover member 4. The first end member 14a is attached to the end of the base member 8 on the +X side (one side in the longitudinal direction X). In other words, the base member 8 supports the first end member 14a. For example, the first end member 14a may be fixed to the base member 8 by a fastening member such as a screw.

[0042] Similarly, the second end member 14b closes the opening in the end face 2b of the housing 2 and the opening in the end face on the -X side of the cover member 4. The second end member 14b is attached to the end of the base member 8 on the -X side (the other side in the longitudinal direction X). In other words, the base member 8 supports the second end member 14b. For example, the second end member 14b may be fixed to the base member 8 by a fastening member such as a screw.

[0043] First end member 14a and second end member 14b each have a communication portion 141. Communication portion 141 connects the inside and outside of housing 2. Communication portion 141 is, for example, a notch. Feeding wiring 31 described with reference to FIG. 1 is inserted through communication portion 141 of second end member 14b. Note that feeding wiring 31 of another lighting fixture 100 may be inserted through communication portion 141 of first end member 14a. First end member 14a and second end member 14b are made of, for example, resin.

[0044] Next, the housing 2 will be further described with reference to Fig. 3. Fig. 3 is a perspective view showing the configuration of the housing 2 included in the lighting fixture 100 of this embodiment. As shown in Fig. 3, the housing 2 has a first wall portion 21 to a third wall portion 23. The first wall portion 21 to the third wall portion 23 each extend in the longitudinal direction X.

[0045] 3, the first wall portion 21 is parallel to the XY plane. The second wall portion 22 protrudes toward the -Z side from the +Y side end of the first wall portion 21. The third wall portion 23 protrudes toward the -Z side from the -Y side end of the first wall portion 21.

[0046] 3, the housing 2 has an insertion hole 21a. An external power supply line VA (see FIG. 4) is inserted through the insertion hole 21a. In this embodiment, the insertion hole 21a is provided in the first wall portion 21.

[0047] Next, the lighting fixture 100 of this embodiment will be further described with reference to Figures 4 and 5. Figure 4 is a side view showing the internal configuration of the lighting fixture 100 of this embodiment. Figure 5 is an enlarged side view showing the power supply unit 10, input line 32, and terminal block 40 included in the lighting fixture 100 of this embodiment. Note that in Figure 4, the two mounting members 12, first end member 14a, and second end member 14b shown in Figure 2 are omitted for simplicity of the drawing. As shown in Figures 4 and 5, the lighting fixture 100 further includes an input line 32 and a terminal block 40.

[0048] 4, the terminal block 40 is disposed on the +Z side of the base member 8. The terminal block 40 is attached to the base member 8. In other words, the base member 8 supports the terminal block 40. For example, the terminal block 40 may be fixed to the base member 8 by a fastening member such as a screw.

[0049] An external power supply line VA is connected to the terminal block 40. More specifically, a plurality of core wires included in the external power supply line VA are connected to the terminal block 40. The terminal block 40 is, for example, a quick-connect terminal.

[0050] The external power supply line VA is inserted through the insertion hole 21a described with reference to FIG. 3 and wired from the outside to the inside of the housing 2. The external power supply line VA includes a power line. The power line includes a power line (core wire) with a positive (+) polarity and a power line (core wire) with a negative (-) polarity. The power line of the external power supply line VA transmits external power. For example, the power line of the external power supply line VA transmits AC power from a commercial power source.

[0051] The external power supply line VA may further include a ground line (core line). The external power supply line VA may further include a signal line. The signal line includes a signal line (core line) with a positive (+) polarity and a signal line (core line) with a negative (-) polarity. The signal line of the external power supply line VA transmits a control signal for controlling the power supply circuit included in the power supply unit 10.

[0052] 5, one end of the input line 32 is electrically connected to the power supply unit 10. The other end of the input line 32 is electrically connected to a terminal block 40. The terminal block 40 supplies external power transmitted through the external power line VA to the input line 32. The input line 32 inputs the external power supplied from the terminal block 40 to the power supply unit 10.

[0053] Specifically, the input line 32 includes a power line. The power line includes a power line (core wire) with a positive (+) polarity and a power line (core wire) with a negative (-) polarity. The power line of the input line 32 transmits external power. For example, the power line of the input line 32 transmits AC power from a commercial power source.

[0054] The input line 32 may further include a ground line (core line). The input line 32 may further include a signal line. The signal line includes a signal line (core line) with a positive (+) polarity and a signal line (core line) with a negative (-) polarity. The signal line transmits a control signal for controlling the power supply circuit included in the power supply unit 10.

[0055] Next, the terminal block 40 will be further described with reference to Figures 6 and 7. Figure 6 is a perspective view showing the terminal block 40. Figure 7 is another perspective view showing the terminal block 40. As shown in Figure 6, the terminal block 40 has a terminal body 41 and four first connection portions 42. As shown in Figure 7, the terminal block 40 further has four second connection portions 43. The terminal block 40 further has four electrodes (not shown) provided inside the terminal body 41.

[0056] The input line 32 described with reference to Figures 4 and 5 is connected to the first connection portion 42 shown in Figure 6. Specifically, two power lines (two core wires) included in the input line 32 are connected to two of the four first connection portions 42.

[0057] More specifically, each of the four first connection portions 42 has an opening formed on the -X side surface of the terminal body 41. Two power lines (two core wires) included in the input line 32 are inserted into two of the four first connection portions 42 (openings) and are electrically connected to two of the four electrodes provided inside the terminal body 41.

[0058] The external power supply line VA described with reference to Figures 4 and 5 is connected to the second connection portion 43 shown in Figure 7. Specifically, two power lines (two core wires) included in the external power supply line VA are connected to two of the four second connection portions 43 that correspond to the first connection portion 42 to which the input line 32 is connected.

[0059] More specifically, each of the four second connection portions 43 has an opening formed on the +X side surface of the terminal body 41. Two power lines (two core wires) included in the external power line VA are inserted into two of the four second connection portions 43 (openings), thereby electrically connecting to two of the four electrodes provided inside the terminal body 41. As a result, the external power line VA is electrically connected to the input line 32 via the electrodes of the terminal block 40.

[0060] Next, the feeding wiring 31 will be described with reference to Fig. 8 and Fig. 9.

[0067] 13, the base member 8 has a first rail portion 84 and a second rail portion 86. The first rail portion 84 is provided at the end of the base member 8 on the +Y side. The second rail portion 86 is provided at the end of the base member 8 on the -Y side. The first rail portion 84 and the second rail portion 86 extend in the longitudinal direction X. The first rail portion 84 and the second rail portion 86 face each other in the Y direction.

[0068] The first rail portion 84 and the second rail portion 86 protrude in the -Z direction relative to the main surface 8a (see FIG. 2) of the base member 8 and sandwich the first substrate 62a. More specifically, a fitting groove extending in the longitudinal direction X is formed on the inner surface of each of the first rail portion 84 and the second rail portion 86. The +Y side end of the first substrate 62a fits into the fitting groove of the first rail portion 84. The -Y side end of the first substrate 62a fits into the fitting groove of the second rail portion 86.

[0069] The first light-emitting module 6a further includes a plurality of first connectors 63a. The plurality of first connectors 63a are mounted on the first substrate 62a at the end of the first light-emitting module 6a on the +X side. The secondary output lines 33a are electrically connected to the plurality of first connectors 63a. Therefore, internal power is transmitted from the secondary output lines 33a to the plurality of first connectors 63a. The internal power transmitted to the plurality of first connectors 63a is supplied to the first light-emitting element 61a via wiring formed on the first substrate 62a.

[0070] 13, each of the multiple first connectors 63a is mounted on the first substrate 62a in an orientation inclined with respect to the longitudinal direction X. As a result, both ends of each first connector 63a can be spaced farther away from the first rail portion 84 and the second rail portion 86 of the base member 8 than when each first connector 63a is mounted on the first substrate 62a in an orientation perpendicular to the longitudinal direction X.

[0071] Next, the second light-emitting module 6b will be described with reference to Fig. 14. Fig. 14 is a diagram showing the second light-emitting module 6b, base member 8, and secondary-side output line 33b included in the lighting fixture 100 of the present embodiment. Specifically, Fig. 14 shows the -X side end of the second light-emitting module 6b as viewed from the -Z side. In the following description, the light-emitting element 61 of the second light-emitting module 6b may be referred to as the "second light-emitting element 61b," and the board 62 of the second light-emitting module 6b may be referred to as the "second board 62b."

[0072] As shown in Fig. 14, the first rail portion 84 and the second rail portion 86 of the base member 8 sandwich the second substrate 62b. Specifically, the +Y side end of the second substrate 62b fits into the fitting groove of the first rail portion 84 described with reference to Fig. 13. The -Y side end of the second substrate 62b fits into the fitting groove of the second rail portion 86 described with reference to Fig. 13.

[0073] The second light-emitting module 6b further includes a plurality of first connectors 63b. The plurality of first connectors 63b are mounted on the second substrate 62b at the end of the second light-emitting module 6b on the -X side. The secondary output lines 33b are electrically connected to the plurality of first connectors 63b. Therefore, internal power is transmitted from the secondary output lines 33b to the plurality of first connectors 63b. The internal power transmitted to the plurality of first connectors 63b is supplied to the second light-emitting element 61b via wiring formed on the second substrate 62b.

[0074] 14, each of the multiple first connectors 63b is mounted on the second substrate 62b in an orientation inclined with respect to the longitudinal direction X. As a result, both ends of each first connector 63b can be spaced farther away from the first rail portion 84 and the second rail portion 86 of the base member 8 than when each first connector 63b is mounted on the second substrate 62b in an orientation perpendicular to the longitudinal direction X.

[0075] Next, the light-emitting module 6 included in the lighting fixture 100 of this embodiment will be further described with reference to Fig. 15. Fig. 15 is a diagram showing the light-emitting module 6, base member 8, and multiple relay power lines 34 included in the lighting fixture 100 of this embodiment. In detail, Fig. 15 shows the vicinity of the boundary between the first light-emitting module 6a and the second light-emitting module 6b as viewed from the -Z side.

[0076] 15, the lighting fixture 100 of this preferred embodiment further includes a plurality of relay power lines 34. The first light-emitting module 6a further includes a plurality of second connectors 64b. The second light-emitting module 6b further includes a plurality of second connectors 64b.

[0077] The plurality of second connectors 64a are mounted on the first substrate 62a at the end on the -X side of the first light emitting module 6a. One ends of the plurality of relay power lines 34 are electrically connected to the plurality of second connectors 64a, respectively. The plurality of second connectors 64b are mounted on the second substrate 62b at the end on the +X side of the second light emitting module 6b. The other ends of the plurality of relay power lines 34 are electrically connected to the plurality of second connectors 64b, respectively. The plurality of relay power lines 34 electrically connect the first substrate 62a and the second substrate 62b.

[0078] 15, each of the multiple second connectors 64a is mounted on the first substrate 62a in an orientation inclined with respect to the longitudinal direction X. As a result, both ends of each second connector 64a can be spaced farther away from the first rail portion 84 and the second rail portion 86 of the base member 8 than when each second connector 64a is mounted on the first substrate 62a in an orientation perpendicular to the longitudinal direction X.

[0079] Similarly, each of the multiple second connectors 64b is mounted on the second substrate 62b in an orientation inclined with respect to the longitudinal direction X. As a result, both ends of each second connector 64b can be spaced farther away from the first rail portion 84 and the second rail portion 86 of the base member 8 than when each second connector 64b is mounted on the second substrate 62b in an orientation perpendicular to the longitudinal direction X.

[0080] Hereinafter, when it is not necessary to distinguish between the first connectors 63a, 63b, 64a, and 64b, the first connectors 63a, 63b, 64a, and 64b may be referred to as "connectors 63, 64." Furthermore, when it is not necessary to distinguish between the first board 62a and the second board 62b, the first board 62a and the second board 62b may be referred to as "board 62."

[0081] According to the present embodiment, since the connectors 63, 64 are mounted on the substrate 62 in an inclined position with respect to the longitudinal direction X, a larger insulation distance can be ensured compared to when the connectors 63, 64 are mounted on the substrate 62 in an orientation perpendicular to the longitudinal direction X. Alternatively, compared to when the connectors 63, 64 are mounted on the substrate 62 in an orientation perpendicular to the longitudinal direction X, the width dimension of the base member 8 and the substrate 62 in the Y direction can be reduced while ensuring the necessary insulation distance, thereby enabling the downsizing of the lighting fixture 100. Furthermore, since both ends of the connectors 63, 64 can be spaced farther away from the first rail portion 84 and the second rail portion 86 of the base member 8, the work of connecting the secondary output lines 33a, 33b and the relay power line 34 to the connectors 63, 64 can be facilitated.

[0082] Next, the power supply unit 10 will be described with reference to Figures 16 and 17. Figure 16 is an exploded perspective view of the power supply unit 10 included in the lighting fixture 100 of this embodiment. As shown in Figure 16, the power supply unit 10 has a power supply main body 101, a case member 102, a first power supply end member 103a, and a second power supply end member 103b.

[0083] The power supply main body 101 is an elongated member extending in the longitudinal direction X. The power supply main body 101 includes the power supply circuit described with reference to FIG. 2. Therefore, the power supply main body 101 generates power to be supplied to the light-emitting module 6. Note that the power supply main body 101 may further include the control circuit described with reference to FIG. 2.

[0084] The case member 102 is a long member that extends in the longitudinal direction X. More specifically, the case member 102 is slightly longer than the power supply main body 101. The case member 102 houses the power supply main body 101.

[0085] The case member 102 has, for example, a rectangular cross section. In other words, the case member 102 may have a substantially rectangular parallelepiped shape with a hollow interior. In this embodiment, the case member 102 has an end face 102a on the +X side (one side in the longitudinal direction X) and an end face (not shown) on the −X side (the other side in the longitudinal direction X) that are open.

[0086] The case member 102 includes an insulating material. For example, the case member 102 is made of resin. Specifically, the case member 102 may be made of polycarbonate or polybutylene terephthalate. The case member 102 may also be an integrally molded product. Specifically, the case member 102 may be an extrusion molded product made of resin. Alternatively, the case member 102 may be molded using a mold.

[0087] According to this embodiment, the case member 102 is an integrally molded product, which eliminates the need for the cumbersome task of folding the insulating sheet multiple times to wrap the power supply main body 101, thereby reducing the burden on the worker.

[0088] The first power supply end member 103a is attached to the end on the +X side of the case member 102 and closes the opening on the end face 102a of the case member 102. The second power supply end member 103b is attached to the end on the -X side of the case member 102 and closes the opening on the end face on the -X side of the case member 102. The first power supply end member 103a and the second power supply end member 103b close the openings on both end faces of the case member 102 in the longitudinal direction X, thereby fixing the power supply main body 101 inside the case member 102.

[0089] The first power supply end member 103a and the second power supply end member 103b include an insulating material. For example, the first power supply end member 103a and the second power supply end member 103b are made of resin. Specifically, the first power supply end member 103a and the second power supply end member 103b may be made of polycarbonate or polybutylene terephthalate.

[0090] FIG. 17 is a perspective view showing an example of the work of housing the power supply main body 101 in the case member 102. As shown in FIG. 17, the worker houses the power supply main body 101 in the case member 102 by inserting the power supply main body 101 into the case member 102 from the opening in the end face 2a of the case member 102. Then, the worker closes the openings on both end faces of the case member 102 in the longitudinal direction X with the first power supply end member 103a and the second power supply end member 103b. Note that before housing the power supply main body 101 in the case member 102, the worker may close the opening on the end face on the -X side of the case member 102 with the second power supply end member 103b.

[0091] 1 to 17, the first embodiment of the present invention has been described. According to this embodiment, the worker can cover the power supply main body 101 with an insulating material by inserting the power supply main body 101 into the case member 102. Therefore, the burden on the worker can be reduced compared to when the power supply main body 101 is wrapped in an insulating sheet.

[0092] Furthermore, according to this embodiment, the number of parts can be reduced compared to a configuration in which the power supply main body 101 is housed in a metal case member, thereby saving resources.

[0093] Furthermore, according to this embodiment, since the housing 2 is made of metal, the power supply main body 101 can be covered with a metal material. Therefore, a metal case for housing the power supply main body 101 is not necessary.

[0094] Note that, with reference to Figure 17, the work of inserting the power supply main body 101 into the inside of the case member 102 from the opening in the end face 2a of the case member 102 has been described, but the worker may also insert the power supply main body 101 from the opening in the end face on the -X side of the case member 102.

[0095] [Embodiment 2] Next, a second embodiment of the present invention will be described with reference to Figures 18 and 19. However, differences from the first embodiment will be described, and a description of the same aspects as in the first embodiment will be omitted. The second embodiment differs from the first embodiment in the configuration of the case member 102.

[0096] Fig. 18 is a side view showing lighting fixture 100 of this embodiment. Fig. 19 is a cross-sectional view taken along line AA in Fig. 18. As shown in Fig. 19, case member 102 has a -Z side wall portion 121 and a holding portion 122. -Z side wall portion 121 extends in the longitudinal direction X. Holding portion 122 holds the wiring.

[0097] Specifically, the holding portion 122 protrudes toward the -Z side from the wall portion 121 on the -Z side of the case member 102. The holding portion 122 extends in the longitudinal direction X. As described in the first embodiment, the secondary output wire 33b is wired between the power supply unit 10 and the base member 8. The holding portion 122 is provided on the base member 8 side of the case member 102, and holds the secondary output wire 33b.

[0098] In this embodiment, the feed wiring 31 (power line) is also wired between the power supply unit 10 and the base member 8. In the lighting fixture 100 of this embodiment, the holding portion 122 further holds the feed wiring 31 (power line).

[0099] More specifically, the holding portion 122 includes a first holding portion 122a and a second holding portion 122b. The first holding portion 122a is provided on the -Y side of the center of the Y direction of the case member 102. The second holding portion 122b is provided on the +Y side of the center of the Y direction of the case member 102.

[0100] The first holding portion 122a holds, for example, the secondary output wire 33b and the feed wiring 31 (power line) having a positive polarity (+ side). In this case, the second holding portion 122b holds the secondary output wire 33b and the feed wiring 31 (power line) having a negative-positive polarity (- side). Alternatively, the first holding portion 122a holds the secondary output wire 33b and the feed wiring 31 (power line) having a negative polarity (- side). In this case, the second holding portion 122b holds the secondary output wire 33b and the feed wiring 31 (power line) having a positive polarity (+ side).

[0101] Specifically, the first holding portion 122a has an outer wall portion 123 and an inner wall portion 124. The outer wall portion 123 and the inner wall portion 124 extend in the longitudinal direction X. The outer wall portion 123 is provided outward from the inner wall portion 124. Specifically, the outer wall portion 123 of the first holding portion 122a is provided on the -Y side from the inner wall portion 124 of the first holding portion 122a. Therefore, the outer wall portion 123 and the inner wall portion 124 face each other in the Y direction.

[0102] The tip end (the end on the -Z side) of the outer wall portion 123 is bent inward. Specifically, the tip end of the outer wall portion 123 of the first holding portion 122a is bent toward the +Y side. The tip end (the end on the -Z side) of the inner wall portion 124 is bent outward. Specifically, the tip end of the inner wall portion 124 of the first holding portion 122a is bent toward the -Y side. In other words, the tip ends of the outer wall portion 123 and the inner wall portion 124 are bent in directions approaching each other.

[0103] The secondary output wire 33b and the feed wiring 31 (power line) are wired between the outer wall portion 123 and the inner wall portion 124. Since the tip portions of the outer wall portion 123 and the inner wall portion 124 are bent in directions approaching each other, the secondary output wire 33b and the feed wiring 31 (power line) are held by the first holding portion 122a.

[0104] Similar to first holding portion 122a, second holding portion 122b also has an outer wall portion 123 and an inner wall portion 124. Outer wall portion 123 of second holding portion 122b is provided on the +Y side of inner wall portion 124 of second holding portion 122b. In addition, the tip of outer wall portion 123 of second holding portion 122b is bent toward the -Y side. The tip of inner wall portion 124 of second holding portion 122b is bent toward the +Y side. The configuration of second holding portion 122b is similar to that of first holding portion 122a, so a detailed description thereof will be omitted.

[0105] Here, the work of attaching the power supply unit 10 to the base member 8 will be described. When attaching the power supply unit 10 to the base member 8, the worker first holds the secondary-side output wire 33b and the feed wiring 31 in the holding portions 122 (the first holding portion 122a and the second holding portion 122b). Thereafter, the worker attaches the power supply unit 10 to the base member 8.

[0106] If the feeding wiring 31 includes a ground wire (core wire), the holding portion 122 also holds the ground wire of the feeding wiring 31. If the feeding wiring 31 includes a signal wire, the holding portion 122 also holds the signal wire of the feeding wiring 31.

[0107] According to this embodiment, the holding portion 122 holds the secondary output wire 33b and the feeding wiring 31, which makes it easier to attach the power supply unit 10 to the base member 8 compared to a configuration in which the secondary output wire 33b and the feeding wiring 31 are not held. This reduces the burden on the worker.

[0108] Specifically, in a configuration in which the secondary output wire 33b and the feeding wiring 31 are not held, when attaching the power supply unit 10 to the base member 8 with screws, one or both of the secondary output wire 33b and the feeding wiring 31 may protrude from the position where the screw is fixed, making it difficult to fasten with the screws. This places a heavy burden on the worker. In contrast, according to this embodiment, the holding portion 122 holds the secondary output wire 33b and the feeding wiring 31, so the secondary output wire 33b and the feeding wiring 31 do not protrude from the position where the screw is fixed. This makes it easier to attach the power supply unit 10 to the base member 8.

[0109] Next, the case member 102 included in the lighting device 100 of this embodiment will be further described with reference to Fig. 19. As shown in Fig. 19, the case member 102 further has a fitting portion 125 that protrudes to the -Z side from a wall portion 121 on the -Z side of the case member 102. The base member 8 also has a fitting groove portion 81 provided on the main surface 8b side (+Z side) of the base member 8.

[0110] The fitting portion 125 is provided at the center of the case member 102 in the Y direction. In other words, the fitting portion 125 is provided between the first holding portion 122a and the second holding portion 122b. The fitting portion 125 extends in the longitudinal direction X. The fitting groove portion 81 is provided at a position facing the fitting portion 125 of the case member 102, and extends in the longitudinal direction X. The fitting groove portion 81 is open on the +Z side.

[0111] The fitting portion 125 is fitted into the fitting groove portion 81. Specifically, the fitting portion 125 has elasticity. The fitting portion 125 fits into the fitting groove portion 81 by the elasticity. By fitting the fitting portion 125 into the fitting groove portion 81, the power supply unit 10 is positioned relative to the base member 8.

[0112] Furthermore, because the power supply unit 10 is a long member, when the +Z side is on the bottom, the central portion of the power supply unit 10 is likely to sag. According to this embodiment, the fitting portion 125 is fitted into the fitting groove portion 81, so the power supply unit 10 is less likely to sag.

[0113] The embodiments of the present invention have been described above with reference to the drawings (FIGS. 1 to 19). However, the present invention is not limited to the above embodiments and can be embodied in various forms without departing from the spirit of the present invention. Furthermore, the components disclosed in the above embodiments can be modified as appropriate. For example, some of the components shown in one embodiment may be added to the components of another embodiment, or some of the components shown in one embodiment may be deleted from the embodiment.

[0114] The drawings mainly show each component in a schematic manner to facilitate understanding of the invention, and the thickness, length, number, spacing, etc. of each component shown in the drawings may differ from the actual ones due to the convenience of creating the drawings. Furthermore, the configuration of each component shown in the above embodiment is merely an example and is not particularly limited, and it goes without saying that various modifications are possible within a range that does not substantially deviate from the effects of the present invention.

[0115] For example, in the embodiment described with reference to FIGS. 1 to 19, lighting fixture 100 includes feed wiring 31, but feed wiring 31 may be omitted.

[0116] Furthermore, in the embodiment described with reference to FIGS. 1 to 19, the lighting device 100 includes a plurality of light-emitting elements 61, but the lighting device 100 may include a single light-emitting element 61.

[0117] 1 to 19, lighting device 100 includes two mounting members 12, but the number of mounting members 12 is not limited to two. As long as power supply unit 10, base member 8, light-emitting module 6, and cover member 4 are supported by housing 2 by the elastic force of mounting members 12, the number of mounting members 12 is not particularly limited.

[0118] Furthermore, in the embodiment described with reference to FIGS. 1 to 19, the terminal block 40 has four first connection portions 42, but the number of first connection portions 42 is not limited to four. The terminal block 40 only needs to have at least two first connection portions 42. Similarly, the terminal block 40 has four second connection portions 43, but the number of second connection portions 43 is not limited to four. The terminal block 40 only needs to have at least two second connection portions 43.

[0119] In the embodiment described with reference to FIGS. 1 to 19, the case member 102 has openings on both end surfaces in the longitudinal direction X. However, the case member 102 may have an opening on only one end surface in the longitudinal direction X. [Industrial Applicability]
