Modes for Carrying Out the Invention

[0016] Hereinafter, embodiments of the lighting fixture, input adapter, output adapter for feeding, and input adapter for feeding according to the present invention will be described with reference to the drawings (FIGS. 1 to 12). However, the present invention is not limited to the following embodiments, and can be implemented in various aspects without departing from the gist thereof. Note that, in cases where the description overlaps, the description may be omitted as appropriate. Also, in the drawings, the same or corresponding parts are denoted by the same reference numerals and the description will not be repeated.

[0017] In this specification, in order to facilitate understanding of the invention, the description may be made with reference to the X direction, Y direction, and Z direction that are orthogonal to each other. For example, the X direction and Y direction are parallel to the horizontal direction, and the Z direction is parallel to the vertical direction. However, the X direction and Y direction 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.

[0018] [Embodiment 1] First, the lighting fixture 100 of the present embodiment will be described with reference to FIG. 1. FIG. 1 is a side view showing the lighting fixture 100 of the present embodiment. As shown in FIG. 1, the lighting fixture 100 includes a fixture body 101. The fixture body 101 has a main body portion 1, a feed wiring 31, and an output connector 32.

[0019] The main body portion 1 emits light. The main body portion 1 extends in the X direction (constant direction). Hereinafter, the direction in which the main body portion 1 extends may be described as the "longitudinal direction X". The feed wiring 31 is drawn out from the inside of the main body portion 1 to the outside. Specifically, the feed wiring 31 is drawn out from the -X side end portion (one end portion in the longitudinal direction X) of the main body portion 1. The output connector 32 is disposed outside the main body portion 1. The output connector 32 is coupled to one end portion of the feed wiring 31 and is electrically connected to the feed wiring 31.

[0020] The feed wiring 31 includes power lines. The power lines include a power line (core wire) with a positive polarity (+ side) and a power line (core wire) with a negative polarity (- side). The power lines of the feed wiring 31 transmit power (external power). For example, the power lines of the feed wiring 31 transmit alternating current power (external power) from a commercial power source.

[0021] The feeder wiring 31 may also include a grounding wire (core wire). One end of the grounding wire may be electrically connected to the base member 8, if the base member 8, which will be described later with reference to Figure 2, is made of metal. For example, one end of the grounding wire may be screwed to the base member 8.

[0022] Furthermore, the feed-through wiring 31 may also include signal lines. The signal lines include a signal line (core wire) with positive polarity (+ side) and a signal line (core wire) with negative polarity (- side). The signal lines of the feed-through wiring 31 transmit control signals to control the main unit 1 included in the other lighting fixture 100. For example, if the control method of the main unit 1 (lighting fixture 100) is the DALI (Digital Addressable Lighting Interface) control method, the signal lines transmit DALI signals. If the control method of the main unit 1 (lighting fixture 100) is the PWM (Pulse Width Modulation) control method, the signal lines transmit PWM signals.

[0023] Next, the main body 1 will be described with reference to Figure 1. As shown in Figure 1, the main body 1 comprises a housing 2 and a cover member 4. The housing 2 and the cover member 4 are both elongated members extending in the longitudinal direction X. The cover member 4 is positioned on the -Z side relative to the housing 2. In other words, the cover member 4 protrudes from the housing 2 on the -Z side. The cover member 4 is, for example, a shade or a diffuser cover.

[0024] Next, the lighting fixture 100 will be further described with reference to Figure 2. Figure 2 is an exploded perspective view of the lighting fixture 100 of this embodiment. More specifically, Figure 2 is an exploded perspective view of the main body 1. Note that in Figure 2, the feed-through wiring 31 and output connector 32 shown in Figure 1 are omitted for the sake of simplifying the drawing.

[0025] As shown in Figure 2, the housing 2 has, for example, a roughly U-shape with sharp corners in cross-sectional view. In other words, the housing 2 is a hollow rectangular parallelepiped, with the -Z side face 2c open. In this embodiment, the housing 2 also has an open end face 2a on the +X side (one side in the longitudinal direction X) and an open end face 2b on the -X side (the other side in the longitudinal direction X). The housing 2 is, for example, a one-piece molded product. The material of the housing 2 is, for example, a metal such as aluminum. The fact that the housing 2 is made of metal improves the heat dissipation of the lighting fixture 100 (fixture body 101).

[0026] The housing 2 (lighting fixture 100) is mounted on a mounting surface such as a ceiling, wall (side wall), or floor. The ceiling surface may be parallel to the horizontal or inclined with respect to the horizontal. When mounting the housing 2 (lighting fixture 100) on a ceiling surface parallel to the horizontal, the +Z side is the upper side and the -Z side is the lower side. The housing 2 (lighting fixture 100) may be directly mounted to the ceiling surface or suspended from the ceiling surface.

[0027] As shown in Figure 2, the main body 1 (lighting fixture 100) further comprises a light-emitting module 6, a base member 8, a power supply unit 10, three mounting members 12, a first end member 14a, and a second end member 14b. The housing 2 accommodates the power supply unit 10, the three mounting members 12, the base member 8, and the light-emitting module 6.

[0028] The light-emitting module 6 is a long member extending in the longitudinal direction X. The light-emitting module 6 emits light. The light-emitting module 6 is an example of a light source. The light-emitting module 6 is positioned on the -Z side of the base member 8. 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 is emitted outside the main body 1 through the cover member 4.

[0029] 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. 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.

[0030] 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 the 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 integrating one light-emitting element 61 and a phosphor, are electrically connected to a conductor on the substrate 62.

[0031] Multiple light-emitting elements 61 are arranged in a single row along the longitudinal direction X. However, the arrangement of the multiple light-emitting elements 61 is not limited to a single row. Multiple light-emitting elements 61 may be arranged in two or more rows along the longitudinal direction X, or they may be arranged in a staggered pattern.

[0032] The main body 1 (lighting fixture 100) may consist of one light-emitting module 6, or it may consist of multiple light-emitting modules 6 arranged along the longitudinal direction X.

[0033] The cover member 4 covers the light-emitting module 6 from the -Z side. The cover member 4 is hollow inside, and its +Z side is open. In this embodiment, the cover member 4 also has an open end face 4a on the +X side (one side in the longitudinal direction X) and an open end face (not shown) on the -X side (the other side in the longitudinal direction X).

[0034] The cover member 4 diffuses the light emitted by the light-emitting module 6, for example. The cover member 4 may be, for example, white and semi-transparent. 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 applying a light-diffusing treatment to the surface.

[0035] The base member 8 is a long member extending in the longitudinal direction X. The base member 8 is, for example, a one-piece molded product. The material of the base member 8 is, for example, a metal such as aluminum. 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. If the base member 8 is made of metal, the base member 8 functions as a heat sink for the light-emitting module 6.

[0036] The power supply unit 10 extends along the longitudinal direction X. The power supply unit 10 has a substantially rectangular parallelepiped shape. The power supply unit 10 is positioned on the +Z side with respect to 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. For example, the power supply unit 10 may be fixed to the base member 8 by fasteners such as screws. If the base member 8 is made of metal, the base member 8 functions as a heat sink for the power supply unit 10.

[0037] 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 produce light from the multiple light-emitting elements 61. 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 secondary output wiring (not shown). For example, if the light-emitting elements 61 are LEDs, the power supply unit 10 generates a DC current.

[0038] Specifically, the power supply unit 10 includes a power supply circuit. The power supply circuit generates internal power based on external power, for example, from a commercial power source. The power supply unit 10 may further include a control circuit that controls the power supply circuit. For example, if the control method of the main unit 1 (lighting fixture 100) is a DALI control method, the control circuit controls the power supply circuit based on a DALI signal. If the control method of the main unit 1 (lighting fixture 100) is a PWM control method, the control circuit controls the power supply circuit based on a PWM signal. The control circuit includes, for example, a microcomputer.

[0039] The three mounting members 12 are positioned on the +Z side relative to the base member 8. The three mounting members 12 are arranged in a row along the longitudinal direction X. The three mounting members 12 are attached to the base member 8. In other words, the base member 8 supports the three mounting members 12. For example, each mounting member 12 may be fixed to the base member 8 by fasteners such as screws.

[0040] Each of the mounting members 12 has elastic force. Each of the mounting members 12 fits into the inside of the housing 2 by elastic force. The base member 8 is attached to the housing 2 by each of the mounting members 12 fitting into the inside of the housing 2.

[0041] The first end member 14a closes the opening on the +X side (one side in the longitudinal direction X) of the main body 1. Specifically, the first end member 14a closes the opening on the end face 2a of the housing 2 and the opening on the end face 4a of the base member 8. The first end member 14a is attached to the +X side (one side in the longitudinal direction X) of the base member 8. 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 fasteners such as screws.

[0042] Similarly, the second end member 14b closes the opening on the -X side of the main body 1 (the opening on the other side in the longitudinal direction X). Specifically, the second end member 14b closes the opening on the end face 2b of the housing 2 and the opening on the -X side of the end face of the base member 8. The second end member 14b is attached to the -X side (the other side in the longitudinal direction X) of the base member 8. 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 fasteners such as screws.

[0043] The first end member 14a and the second end member 14b each have a connecting portion 141. The connecting portion 141 connects the inside and outside of the main body 1. The connecting portion 141 is, for example, a notch. The feed wiring 31, described with reference to Figure 1, is inserted through the connecting portion 141 of the second end member 14b. The feed wiring 31 of another lighting fixture 100 is inserted through the connecting portion 141 of the first end member 14a. The first end member 14a and the second end member 14b are made of, for example, resin.

[0044] Next, the housing 2 will be described further with reference to Figure 3. Figure 3 is a perspective view of the housing 2 included in the lighting fixture 100 of this embodiment. As shown in Figure 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] As shown in Figure 3, the first wall portion 21 is parallel to the XY plane. The second wall portion 22 protrudes from the +Y end of the first wall portion 21 toward the -Z side. The third wall portion 23 protrudes from the -Y end of the first wall portion 21 toward the -Z side.

[0046] As shown in Figure 3, the housing 2 has a through hole 21a. An external power line VA is inserted through the through hole 21a. In this embodiment, the through 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 to 6. Figure 4 is a partially exploded perspective view showing the configuration of the lighting fixture 100 of this embodiment. Figure 5 is a side view showing the power supply unit 10, input line 33, input connector 34, and input adapter 40 included in the lighting fixture 100 of this embodiment. Figure 6 is another side view showing the power supply unit 10, input line 33, input connector 34, and input adapter 40 included in the lighting fixture 100 of this embodiment. Specifically, Figure 5 shows the state in which the input connector 34 and input adapter 40 are connected. Figure 6 shows the state in which the input connector 34 and input adapter 40 are not connected. As shown in Figures 4 to 6, the lighting fixture 100 further comprises an input adapter 40. The fixture body 101 further comprises an input line 33 and an input connector 34.

[0048] One end of the input line 33 is electrically connected to the power supply unit 10. The input line 33 supplies external power to the power supply unit 10. Specifically, the input line 33 includes power lines. The power lines include power lines (core wires) with positive polarity (+ side) and power lines (core wires) with negative polarity (- side). The power lines of the input line 33 transmit external power. For example, the power lines of the input line 33 transmit AC power from a commercial power source.

[0049] The input line 33 may also include a ground wire (core wire). Furthermore, the input line 33 may also include signal lines. The signal lines include a signal line (core wire) with positive polarity (+ side) and a signal line (core wire) with negative polarity (- side). The signal lines transmit control signals to control the main unit 1.

[0050] The input connector 34 connects to the other end of the input wire 33, thereby electrically connecting to the input wire 33. The input adapter 40 is detachably connected to the input connector 34. When the input adapter 40 and the input connector 34 are physically connected, the input adapter 40 is electrically connected to the input connector 34. The input adapter 40 supplies external power to the power supply unit 10 via the input connector 34 and the input wire 33.

[0051] Specifically, the input adapter 40 has a terminal section 41 and a connector section 42. An external power line VA is connected to the terminal section 41. More specifically, multiple core wires included in the external power line VA are connected to the terminal section 41. The terminal section 41 is, for example, a quick-connect terminal. The input adapter 40 supplies the external power input to the terminal section 41 to the input connector 34 from the connector section 42.

[0052] The external power line VA is inserted through the insertion hole 21a, as described with reference to Figure 3, and wired from the outside to the inside of the main body 1. The external power line VA includes power lines. The power lines include power lines (core wires) with positive polarity (+ side) and power lines (core wires) with negative polarity (- side). The power lines of the external power line VA transmit external power. For example, the power lines of the external power line VA transmit AC power from the commercial power supply. The external power line VA is, for example, a VVF cable (Vinyl insulated Vinyl sheathed Flat-type cable). The external power line VA is an example of an external power line.

[0053] The external power line VA may also include a grounding wire (core wire). One end of the grounding wire may be electrically connected to the base member 8, if the base member 8, as described with reference to Figure 2, is made of metal. For example, one end of the grounding wire may be screwed to the base member 8.

[0054] Furthermore, the external power line VA may also include signal lines. The signal lines include a signal line (core wire) with positive polarity (+ side) and a signal line (core wire) with negative polarity (- side). The signal lines of the external power line VA transmit control signals to control the main unit 1.

[0055] Here, the terminal section 41 will be explained further. The terminal section 41 comprises a terminal body made of an insulator such as resin. The terminal body of the terminal section 41 has multiple openings into which multiple core wires included in the external power line VA can be inserted. The terminal section 41 also has multiple electrodes provided inside the terminal body. Each of the multiple electrodes corresponds to one of the multiple openings of the terminal body. The multiple core wires included in the external power line VA are inserted into the multiple openings of the terminal section 41 (terminal body) and electrically connected to the multiple electrodes inside the terminal body.

[0056] The connector section 42 is detachably connected to the input connector 34. When the connector section 42 is connected to the input connector 34, the connector section 42 and the input connector 34 are electrically connected. The input adapter 40 supplies external power transmitted from the external power line VA to the terminal section 41 to the input connector 34 via the connector section 42.

[0057] Here, the connector section 42 and the input connector 34 will be further described. The connector section 42 comprises a connector body made of an insulator such as resin. The connector section 42 also comprises a plurality of electrodes provided inside the connector body. The input connector 34 comprises a connector body made of an insulator such as resin. The connector body of the input connector 34 has an opening into which the connector body of the connector section 42 can be inserted. The input connector 34 also comprises a plurality of electrodes provided inside the connector body. The connector section 42 (connector body) is inserted into the opening of the input connector 34 (connector body), and the plurality of electrodes of the connector section 42 are electrically connected to the plurality of electrodes of the input connector 34.

[0058] For example, the input connector 34 may have multiple pin-shaped electrodes. Alternatively, the connector part 42 may have multiple pin-shaped electrodes. If the input connector 34 has multiple pin-shaped electrodes, the connector body of the connector part 42 has multiple pin insertion openings into which the multiple pin-shaped electrodes of the input connector 34 can be inserted. Each of the multiple electrodes of the connector part 42 corresponds to one of the multiple pin insertion openings. When the connector part 42 is connected to the input connector 34, the multiple pin-shaped electrodes of the input connector 34 are inserted into the multiple pin insertion openings of the connector part 42, respectively, and electrically connected to the multiple electrodes of the connector part 42. The same applies if the connector part 42 has multiple pin-shaped electrodes.

[0059] Furthermore, if the external power line VA includes a signal line, the input adapter 40 transmits the control signal transmitted from the external power line VA to the terminal section 41 to the input connector 34 via the connector section 42. As a result, the control signal is input to the power supply unit 10.

[0060] In this embodiment, the terminal section 41 and the connector section 42 are separate components, and the input adapter 40 further includes a relay power line 43. One end of the relay power line 43 is connected to the terminal section 41, and the other end of the relay power line 43 is connected to the connector section 42. The relay power line 43 electrically connects the terminal section 41 and the connector section 42.

[0061] The relay power line 43 includes power lines. The power lines include power lines (core wires) with positive polarity (+ side) and power lines (core wires) with negative polarity (- side). The power lines of the relay power line 43 transmit external power. For example, the power lines of the relay power line 43 transmit AC power from the commercial power supply. The relay power line 43 is an example of a relay power line.

[0062] The relay power line 43 may further include a ground wire (core wire). The relay power line 43 may also further include signal lines. The signal lines include a signal line (core wire) with positive polarity (+ side) and a signal line (core wire) with negative polarity (- side). The signal lines of the relay power line 43 transmit control signals for controlling the main unit 1.

[0063] Here, with reference to Figures 4 to 6, the work performed by the worker during the installation of the lighting fixture 100 will be explained. First, the worker inserts the external power line VA through the insertion hole 21a, as explained with reference to Figure 3, and pulls the external power line VA inside the main body 1. After that, the worker connects the external power line VA to the terminal section 41 of the input adapter 40. After connecting the external power line VA to the terminal section 41 of the input adapter 40, the worker connects the connector section 42 of the input adapter 40 to the input connector 34.

[0064] As explained with reference to Figures 4 to 6, the worker only needs to connect the external power line VA to the terminal portion 41 of the input adapter 40, which is not fixed to the main unit 101. Therefore, compared to the case where the external power line VA is connected to a terminal block fixed to the main unit 1, the burden on the worker in connecting the external power line VA can be reduced. For example, if the external power line VA includes a power line, a signal line, and a grounding line, in the configuration where the external power line VA is connected to a terminal block fixed to the main unit 1, it is necessary to connect five core wires to the terminal block fixed to the main unit 1, which places a heavy burden on the worker. In contrast, according to this embodiment, the external power line VA only needs to be connected to the terminal portion 41 of the input adapter 40, which is not fixed to the main unit 101, thus reducing the burden on the worker.

[0065] Next, with reference to Figure 7, the wiring work for connecting two lighting fixtures 100 will be explained. Figure 7 is a perspective view showing the wiring work for connecting two lighting fixtures 100.

[0066] Hereinafter, of the two lighting fixtures 100, the lighting fixture 100 to which the external power line VA, as explained with reference to Figures 4 to 7, is connected will be referred to as "First Lighting Fixture 100A," and the other lighting fixture 100 will be referred to as "Second Lighting Fixture 100B." Furthermore, the fixture body 101 of the First Lighting Fixture 100A will be referred to as "First Fixture Body 101A," and the fixture body 101 of the Second Lighting Fixture 100B will be referred to as "Second Fixture Body 101B." Note that in the example shown in Figure 7, at least the Second Lighting Fixture 100B does not include the input adapter 40.

[0067] As shown in Figure 7, during wiring work, the worker connects the output connector 32 of the first lighting fixture 100A to the input connector 34 of the second lighting fixture 100B. As a result, the output connector 32 of the first lighting fixture 100A and the input connector 34 of the second lighting fixture 100B are electrically connected. With the output connector 32 of the first lighting fixture 100A and the input connector 34 of the second lighting fixture 100B electrically connected, the external power transmitted by the feed-through wiring 31 of the first lighting fixture 100A is input to the power supply unit 10 of the second lighting fixture 100B via the output connector 32 of the first lighting fixture 100A, the input connector 34 of the second lighting fixture 100B, and the input line 33 of the second lighting fixture 100B.

[0068] The feeder wiring 31 branches off from the input line 33, as explained with reference to Figures 4 to 6. Therefore, external power is supplied from the input line 33 to the feeder wiring 31. The feeder wiring 31 transmits the external power supplied from the input line 33 to the output connector 32. The feeder wiring 31 may, for example, extend along the longitudinal direction X between the base member 8 and the power supply unit 10.

[0069] When the first lighting fixture 100A and the second lighting fixture 100B are connected, the feeder wiring 31 of the first lighting fixture 100A is routed from the first fixture body 101A to the second fixture body 101B, passing through the connecting portion 141 of the second end member 14b of the first lighting fixture 100A and the connecting portion 141 of the first end member 14a of the second lighting fixture 100B. The first fixture body 101A and the second fixture body 101B are connected by a connecting fitting CN, as shown in Figure 7.

[0070] As described above with reference to Figure 7, according to this embodiment, when connecting multiple lighting fixtures 100, the worker only needs to connect the output connector 32 and the input connector 34. Therefore, compared to the case where the feed-through wiring 31 is connected to a terminal block fixed to the main body 1, the burden of wiring work when connecting multiple lighting fixtures 100 can be reduced. For example, if the feed-through wiring 31 includes power lines, signal lines, and ground lines, in the configuration where the feed-through wiring 31 is connected to a terminal block, it is necessary to connect five core wires to the terminal block fixed to the main body 1. In contrast, according to this embodiment, it is only necessary to connect the output connector 32 and the input connector 34, thus reducing the burden on the worker.

[0071] Next, a modified example of the input adapter 40 will be described with reference to Figure 8. Figure 8 is a side view showing a modified example of the input adapter 40 in this embodiment. Hereinafter, the input adapter 40 shown in Figures 4 to 6 will be referred to as "input adapter 40A," and the input adapter 40 shown in Figure 8 will be referred to as "input adapter 40B."

[0072] As shown in Figure 8, the input adapter 40B omits the relay power line 43 compared to the input adapter 40A. Specifically, the input adapter 40B has a terminal section 41B and a connector section 42B. In the input adapter 40B, the terminal section 41B and the connector section 42B are integrated. More specifically, inside the input adapter 40B, the electrical circuit of the terminal section 41B and the electrical circuit of the connector section 42B are electrically connected.

[0073] Embodiment 1 of the present invention has been described above with reference to Figures 1 to 8. According to this embodiment, the burden on workers can be reduced.

[0074] Furthermore, according to this embodiment, since the input adapter 40 and the fixture body 101 are separate (detachable), the configuration of the fixture body 101 that connects to the external power line VA and the configuration of the fixture body 101 that connects to the feed-through wiring 31 of other lighting fixtures 100 can be standardized. In other words, there is no need to manufacture the fixture body 101 that connects to the external power line VA and the fixture body 101 that connects to the feed-through wiring 31 of other lighting fixtures 100 with different specifications. As a result, compared to the case where two types of fixture body 101 are manufactured—one for connecting to the external power line VA and the other for connecting to the feed-through wiring 31 of other lighting fixtures 100—inventory management becomes easier for, for example, the manufacturer or seller of the lighting fixtures 100.

[0075] Furthermore, according to this embodiment, when an installer of lighting fixtures 100 attempts to install multiple lighting fixtures 100 in a connected manner, they only need to order multiple fixture bodies 101 of the same type, thus simplifying the ordering process and reducing ordering errors. Also, since there is only one type of fixture body 101, when an installer connects multiple lighting fixtures 100, they can perform the installation work of the fixture bodies 101 without having to be aware of the type of fixture body 101. Therefore, the installation work becomes easier.

[0076] Furthermore, according to this embodiment, since the input adapter 40 and the fixture body 101 are separate (detachable), the input adapter 40 and the fixture body 101 can be distributed individually. In other words, the input adapter 40 does not need to be an accessory of the lighting fixture 100. That is, the input adapter 40 and the fixture body 101 do not need to be bundled together.

[0077] [Embodiment 2] Next, Embodiment 2 of the present invention will be described with reference to Figures 9 to 12. However, only the differences from Embodiment 1 will be described, and the same matters as in Embodiment 1 will be omitted. Embodiment 2 differs from Embodiment 1 in that the lighting fixture 100 further comprises a feed output adapter 70 and a feed input adapter 80. In the following description, the external power line VA connected to the input adapter 40 will be referred to as "first external power line VA1".

[0078] Figure 9 is a block diagram showing the configuration of a lighting system 1000 including the lighting fixture 100 of this embodiment. In the example shown in Figure 9, the lighting system 1000 includes two lighting fixtures 100 (a first lighting fixture 100A and a second lighting fixture 100B). The two lighting fixtures 100 (the first lighting fixture 100A and the second lighting fixture 100B) are placed apart from each other.

[0079] As shown in Figure 9, in the lighting system 1000, the first lighting fixture 100A includes an input adapter 40, a feed output adapter 70, and a feed input adapter 80. As explained with reference to Figures 1 to 8, external power is input to the input adapter 40. For example, as shown in Figure 9, AC power from the commercial power supply G is input to the input adapter 40 via the first external power line VA1. On the other hand, the second lighting fixture 100B does not include the input adapter 40, the feed output adapter 70, and the feed input adapter 80.

[0080] The feed-through output adapter 70 is an adapter for transmitting external power from the first lighting fixture 100A to the second lighting fixture 100B. The feed-through output adapter 70 comprises a feed-through first connector section 71 and a feed-through first terminal section 72. The feed-through first connector section 71 is connected to the output connector 32 of the first lighting fixture 100A. The second external power line VA2 is connected to the feed-through first terminal section 72. The feed-through output adapter 70 supplies the external power transmitted from the output connector 32 of the first lighting fixture 100A to the feed-through first connector section 71 to the second external power line VA2 via the feed-through first terminal section 72.

[0081] More specifically, the first feed connector section 71 is detachably connected to the output connector 32. When the first feed connector section 71 is connected to the output connector 32, the first feed connector section 71 and the output connector 32 are electrically connected. Note that the configuration of the first feed connector section 71 and the output connector 32 is substantially the same as the configuration of the connector section 42 and the input connector 34, so a detailed explanation is omitted.

[0082] One end of each of the multiple core wires included in the second external power line VA2 is connected to the first feed terminal 72. The first feed terminal 72 is, for example, a quick-connect terminal. In the example shown in Figure 9, the second external power line VA2 includes a power line and a ground wire (core wire). The power line includes a power line (core wire) with positive polarity (+ side) and a power line (core wire) with negative polarity (- side). One end of the three core wires included in the second external power line VA2 is connected to the first feed terminal 72. The second external power line VA2 is, for example, a VVF cable. The second external power line VA2 is an example of an external power line.

[0083] The second external power line VA2 may also include signal lines. The signal lines include a signal line (core wire) with positive polarity (+ side) and a signal line (core wire) with negative polarity (- side). The signal lines of the second external power line VA2 transmit control signals to control the second lighting fixture 100B.

[0084] In this embodiment, the first feed connector section 71 and the first feed terminal section 72 are separate components, and the feed output adapter 70 further includes a first feed relay power line 73. The first feed relay power line 73 transmits external power from the first feed connector section 71 to the first feed terminal section 72. Specifically, one end of the first feed relay power line 73 is connected to the first feed connector section 71, and the other end of the first feed relay power line 73 is connected to the first feed terminal section 72. The first feed relay power line 73 electrically connects the first feed connector section 71 and the first feed terminal section 72. The first feed relay power line 73 is an example of a relay power line.

[0085] The feed input adapter 80 is an adapter for transmitting external power from the first lighting fixture 100A to the second lighting fixture 100B. The feed input adapter 80 includes a feed second connector section 81 and a feed second terminal section 82.

[0086] The second feed connector section 81 is connected to the input connector 34 of the second lighting fixture 100B. The second external power line VA2 is connected to the second feed terminal section 82. The second external power line VA2 transmits the external power supplied from the first lighting fixture 100A. More specifically, the second external power line VA2 transmits the external power supplied from the feed output adapter 70.

[0087] The feed input adapter 80 supplies external power transmitted from the second external power line VA2 to the second feed terminal section 82 to the input connector 34 of the second lighting fixture 100B via the second feed connector section 81. As a result, external power is supplied from the first lighting fixture 100A to the power supply section 10 of the second lighting fixture 100B.

[0088] More specifically, the second feed connector section 81 is detachably connected to the input connector 34. When the second feed connector section 81 is connected to the input connector 34, the second feed connector section 81 and the input connector 34 are electrically connected. Note that the configuration of the second feed connector section 81 and the input connector 34 is substantially the same as the configuration of the connector section 42 and the input connector 34, so a detailed explanation is omitted.

[0089] The other end of each of the multiple core wires included in the second external power line VA2 is connected to the second feed terminal 82. The second feed terminal 82 is, for example, a quick-connect terminal. In the example shown in Figure 9, three core wires included in the second external power line VA2 are connected to the second feed terminal 82.

[0090] In this embodiment, the second feed connector section 81 and the second feed terminal section 82 are separate components, and the feed input adapter 80 further includes a second feed relay power line 83. The second feed relay power line 83 transmits external power from the second feed terminal section 82 to the second feed connector section 81. Specifically, one end of the second feed relay power line 83 is connected to the second feed connector section 81, and the other end of the second feed relay power line 83 is connected to the second feed terminal section 82. The second feed relay power line 83 electrically connects the second feed connector section 81 and the second feed terminal section 82. The second feed relay power line 83 is an example of a relay power line.

[0091] In the example shown in Figure 9, the output connector 32 is located inside the main body 1, but as explained with reference to Figures 1 and 7, the output connector 32 may be located outside the main body 1.

[0092] Next, the feed output adapter 70 will be described with reference to Figure 10. Figure 10 is a plan view showing the feed output adapter 70 of this embodiment. As shown in Figure 10, in this embodiment, the first feed terminal section 72 includes three terminal sections 72a to 72c. The first feed relay power line 73 includes a power line 73a with positive polarity, a ground line 73b, and a power line 73c with negative polarity.

[0093] The power line 73a of the first relay power line 73 for sending power is connected to terminal 72a. In addition, the power line with positive polarity included in the second external power line VA2 is connected to terminal 72a. Terminal 72a electrically connects the power line 73a of the first relay power line 73 for sending power to the power line with positive polarity included in the second external power line VA2. Terminal 72a is, for example, a quick-connect terminal.

[0094] More specifically, the terminal section 72a comprises a terminal body formed of an insulator such as resin. The terminal body of the terminal section 72a has an opening into which a power line with positive polarity included in the second external power line VA2 can be inserted. The terminal section 72a also has electrodes provided inside the terminal body. A power line with positive polarity included in the second external power line VA2 is inserted into the opening of the terminal section 72a (terminal body) and electrically connected to the electrodes inside the terminal body. As a result, the power line 73a of the first relay power line 73 for sending power is electrically connected to the power line with positive polarity included in the second external power line VA2.

[0095] The ground wire 73b of the first relay power line 73 for sending power is connected to terminal section 72b. Additionally, the ground wire included in the second external power line VA2 is connected to terminal section 72b. Terminal section 72b connects the ground wire 73b of the first relay power line 73 to the ground wire included in the second external power line VA2. Terminal section 72b is, for example, a quick-connect terminal. The configuration of terminal section 72b is substantially the same as that of terminal section 72a, so its explanation is omitted.

[0096] The power line 73c of the first relay power line 73 for sending power is connected to terminal section 72c. Additionally, the power line with negative polarity included in the second external power line VA2 is connected to terminal section 72c. Terminal section 72c electrically connects the power line 73c of the first relay power line 73 to the power line with negative polarity included in the second external power line VA2. Terminal section 72c is, for example, a quick-connect terminal. The configuration of terminal section 72c is substantially the same as that of terminal section 72a, so its explanation is omitted.

[0097] In the example shown in Figure 10, the terminals 72a to 72c are separate, but they may be integrated, for example, as in the terminal 41 of the input adapter 40.

[0098] Next, the feed input adapter 80 will be described with reference to Figure 11. Figure 11 is a plan view showing the feed input adapter 80 of this embodiment. As shown in Figure 11, in this embodiment, the second feed terminal section 82 includes three terminal sections 82a to 82c. The second feed relay power line 83 includes a power line 83a with positive polarity, a ground line 83b, and a power line 83c with negative polarity.

[0099] Terminal 82a is connected to the power line 83a of the second relay power supply line 83 for sending power. In addition, the power line with positive polarity included in the second external power supply line VA2 is connected to terminal 82a. Terminal 82b is connected to the ground wire 83b of the second relay power supply line 83 for sending power. In addition, the ground wire included in the second external power supply line VA2 is connected to terminal 82b. Terminal 82c is connected to the power line 83c of the second relay power supply line 83 for sending power. In addition, the power line with negative polarity included in the second external power supply line VA2 is connected to terminal 82c. Terminals 82a to 82c are, for example, quick-connect terminals. The configuration of terminals 82a to 82c is substantially the same as the configuration of terminals 72a to 72c described with reference to Figure 10, so their explanation is omitted.

[0100] In the example shown in Figure 11, the terminal sections 82a to 82c are separate, but they may be integrated, for example, as in the terminal section 41 of the input adapter 40.

[0101] Next, another example of the lighting system 1000 including the lighting fixture 100 of this embodiment will be described. Figure 12 is a block diagram showing another configuration of the lighting system 1000 including the lighting fixture 100 of this embodiment. In the lighting system 1000 described with reference to Figures 9 to 11, the ground wire of the second external power line VA2 was connected to the first feed terminal 72 and the second feed terminal 82. However, the lighting system 1000 may be configured in which the ground wire of the second external power line VA2 is not connected to the first feed terminal 72 and the second feed terminal 82, as shown in Figure 12.

[0102] In this embodiment, the lighting system 1000 includes two lighting fixtures 100, but the number of lighting fixtures 100 is not limited to two. The number of lighting fixtures 100 may be three or more.

[0103] Furthermore, although the first feed connector section 71 and the first feed terminal section 72 were separate in this embodiment, they may be integrated, similar to the input adapter 40B described with reference to Figure 8. Also, although the second feed connector section 81 and the second feed terminal section 82 were separate in this embodiment, they may be integrated.

[0104] As described above with reference to Figures 9 to 12, according to this embodiment, the second external power line VA2 can be used to transmit external power from the first lighting fixture 100A to the second lighting fixture 100B. Therefore, the first lighting fixture 100A and the second lighting fixture 100B can be placed at any desired distance from each other. As a result, the burden on the worker installing the lighting fixtures 100 can be reduced.

[0105] For example, when connecting the output connector 32 and the input connector 34 as explained with reference to Figure 7, the distance between the first lighting fixture 100A and the second lighting fixture 100B is constrained by the length of the feed-through wiring 31. Therefore, the degree of freedom in arranging the first lighting fixture 100A and the second lighting fixture 100B is restricted, which may make the installation of the lighting fixtures 100 difficult. In contrast, according to this embodiment, there is no restriction on the distance between the first lighting fixture 100A and the second lighting fixture 100B, so the first lighting fixture 100A and the second lighting fixture 100B can be freely arranged. As a result, the burden on the worker is reduced.

[0106] Furthermore, according to this embodiment, since the output adapter 70 and input adapter 80 for sending power and the fixture body 101 are separate (detachable), the configuration of the fixture body 101 can be standardized. As a result, inventory management by the manufacturer or seller of the lighting fixture 100 and ordering by the installer become easier, and ordering errors can also be reduced.

[0107] Furthermore, according to this embodiment, the configuration of the fixture body 101 can be standardized, so when installing multiple lighting fixtures 100, the installer can perform the installation work of the lighting fixtures 100 without having to be aware of the type of fixture body 101. Therefore, the installation work becomes easier.

[0108] Furthermore, according to this embodiment, since the output adapter 70 and input adapter 80 and the fixture body 101 are separate (detachable), the output adapter 70, input adapter 80, and fixture body 101 can be distributed individually. In other words, the output adapter 70 and input adapter 80 do not need to be included as accessories with the lighting fixture 100. That is, the output adapter 70 and input adapter 80 and the fixture body 101 do not need to be bundled together.

[0109] Embodiments of the present invention have been described above with reference to the drawings (Figures 1 to 12). It should be noted that the present invention is not limited to the embodiments described above, and can be implemented in various forms without departing from its essence. Furthermore, the multiple components disclosed in the above embodiments can be modified as appropriate. For example, some components from all the components shown in one embodiment may be added to the components of another embodiment, or some components from all the components shown in one embodiment may be removed from the embodiment.

[0110] The drawings schematically show each component in order to facilitate understanding of the invention, and the thickness, length, number, spacing, etc. of each component shown may differ from the actual dimensions due to the convenience of drawing creation. Furthermore, the configuration of each component shown in the above embodiments is merely an example and is not particularly limiting, and it goes without saying that various modifications are possible without substantially departing from the effects of the present invention.

[0111] For example, in the embodiment described with reference to Figures 1 to 8, the lighting fixture 100 is equipped with feeder wiring 31 and an output connector 32, but the feeder wiring 31 and the output connector 32 may be omitted.

[0112] Furthermore, in the embodiment described with reference to Figures 1 to 12, the lighting fixture 100 is equipped with multiple light-emitting elements 61, but the lighting fixture 100 may be equipped with only one light-emitting element 61.

[0113] Furthermore, in the embodiment described with reference to Figures 1 to 12, the lighting fixture 100 is equipped with three mounting members 12, but the number of mounting members 12 is not limited to three. The number of mounting members 12 is not particularly limited as long as the power supply unit 10, base member 8, light-emitting module 6, and cover member 4 are supported by the elastic force of the mounting members 12 in the housing 2. [Industrial applicability]
