[1. First Embodiment]
Hereinafter, a form (this embodiment) for carrying out the present invention will be described with reference to the drawings. First, the overall configuration (including the internal configuration) of the lighting fixture of this embodiment will be described, and then the shape of the cover member provided in the lighting fixture of this embodiment will be described.

  FIG. 1 is a perspective view from below showing the appearance of the lighting apparatus 100 of the first embodiment. The lighting fixture 100 is attached to the ceiling 150. The lighting fixture 100 includes a metal main unit 10 and a cover member 20 (for example, made of resin) that is attached to the main unit 10 and has an arc shape. Inside the main unit 10 (a space formed by attaching the cover member 20, the same applies hereinafter), a light source unit 27 (described later with reference to FIG. 3) and the like that generates emitted light is provided outside. Yes.

  FIG. 2 is a diagram illustrating a state when the cover member 20 is removed from the main body unit 10 of the lighting apparatus 100 according to the first embodiment. FIG. 2A illustrates a state in which the user's hand H holds the cover member 20. a) shows a state in which the user's hand H has removed the cover member 20 by pulling it downward. 2B will be described later with reference to FIG. 5, and therefore the description of the A portion is omitted in the description of FIG. Further, in FIG. 2B, illustration of each member housed in the main unit 10 is omitted for simplification of illustration.

  As shown in FIG. 2A, the user can easily grasp the cover member 20 by grasping the dent 21 provided on the side surface of the cover member 20 with the hand H. In this state, when the user pulls the cover member 20 downward, the cover member 20 is removed from the main unit 10. As a result, the cover member 20 is separated from the main unit 10. The cover member 20 is attached to the main unit 10 by a guide member 31 that extends in the vertical direction with respect to the cover member 20.

  FIG. 3 is a diagram illustrating a state where the cover member 20 is removed from the main body unit 10 of the lighting fixture 100 of the first embodiment. A power terminal block 12 is fixed to the main unit 10. Further, a lighting device 26 and a light source unit 27 connected to the lighting device 26 are fixed inside the cover member 20. The lighting device 26 controls the light source unit 27. Specifically, the lighting device 26 controls lighting and extinguishing of the light source unit 27, intensity of light emitted from the light source unit 27, and the like. As the light source unit 27, for example, an LED, an organic EL, a fluorescent tube, or the like can be applied. Among these, an LED is preferable from the viewpoint of energy saving.

  A power line 13 connected to an AC power source (not shown) is connected to the power terminal block 12. Further, a ground wire (not shown) is connected to the power terminal block 12. The power supply terminal block 12 and the lighting device 26 are connected in this order from the power supply terminal block 12 via the power supply line 14, the power supply connector 15, the power supply connector 24, and the power supply line 25. Thereby, the electric power from AC power supply is supplied to the lighting device 26. Thereby, the electric power supplied from the power supply device to the lighting device 26 is used for driving the light source unit 27.

  The lighting device 26 is connected to a light control device (not shown) via a signal line. Specifically, the lighting device 26 and the light control device are arranged in this order from the lighting device 26 side in the order of the signal line 23, the signal terminal block 22, and the signal connection portion 16 (see FIG. 4, not shown in FIG. 3). ) And the signal line 11. When the user operates the light control device (for example, rotates a knob constituting the light control device), an electrical signal corresponding to the degree of the operation is generated. The generated electrical signal is transmitted to the lighting device 26 through the signal line 11, the signal line 23, and the like, so that the lighting device 26 controls driving (brightness, etc.) of the light source unit 27 according to the electrical signal. It is supposed to be.

  FIG. 4 is a diagram illustrating a state in which the connection between the signal line 11 and the power supply line 14 on the main unit 10 side and the signal line 23 and the power supply line 25 on the cover member 20 side is released in the state of FIG. 3. For example, when the cover member 20 is attached to the main unit 10 in the state of FIG. 4 after the maintenance of the lighting fixture 100, the following procedure can be applied.

  First, as shown in FIG. 4, the cover member 20 is arranged so that the signal connection portion 16 that is an end portion of the signal line 11 and the signal terminal block 22 that is an end portion of the signal line 23 are connected. Thereby, electrical connection between the light control device and the lighting device 26 is achieved. Further, the power connector 15 that is the end portion of the power line 14 and the power connector 24 that is the end portion of the power line 25 are connected. Thereby, electrical connection between the AC power source and the lighting device 26 is achieved. Then, finally, by attaching the cover member 20 to the main unit 10 in the reverse order of the procedure described with reference to FIG.

  As shown in FIGS. 3 and 4, in the lighting fixture 100 of the first embodiment, the signal terminal block 22 is not fixed to either the main unit 10 or the cover member 20. That is, the signal terminal block 22 is not supported with respect to the main unit 10 and the cover member 20. Thereby, unlike the conventional lighting fixture (for example, refer to the above-mentioned patent document 1) in which the signal terminal block 22 is fixed to the main body unit 10, the connection between the signal terminal block 22 and the signal connection portion 16 is connected to the main body cover 20. Can be performed in the vicinity. Accordingly, the signal connection portion 16 and the signal terminal block 22 can be connected and detached at a position lower than the position of the ceiling 150 and the like. Thereby, it becomes possible to perform connection and detachment while checking the hand, and the maintenance and the like of the lighting apparatus 100 are facilitated.

  Further, by separating the signal terminal block 22 that has been conventionally fixed to the main unit 10 independently (that is, from the main unit 10), only the power terminal block 12 is fixed to the main unit 10 as a terminal block. . Even when the user does not need the dimming function, the main unit 10 shown in FIGS. 3 and 4 can be used. Therefore, the versatility of the main unit 10 can be improved, and a single type of main unit 10 may be prepared for various cover members 20 (including the lighting device 26 and the light source unit 27).

  Furthermore, in the conventional lighting fixture in which the signal terminal block 22 is fixed to the main body unit 10, the lighting device 26 is provided on the cover member 20 side, and therefore, the signal line that connects the signal terminal block 22 and the lighting device 26. In the meantime, a signal connector was provided. However, as in the lighting fixture 100 of the first embodiment, the signal terminal block 22 is separated from the main body unit 10 to be independent so that the signal connection unit 16 may be directly connected to the signal terminal block 22. Thereby, the signal connector used conventionally can be reduced.

  Next, the cover member 20 which comprises the lighting fixture 100 of 1st Embodiment is demonstrated.

  5A is an enlarged view of a portion A in FIG. 2B, and FIGS. 5B to 5F are diagrams showing modifications of FIG. As illustrated in FIG. 5A, an R-shaped recess 21 having a curved shape is formed on the side surface of the cover member 20. The dent 21 is formed between a dent upper end 20a that projects outward from the cover member 20 and a dent lower end 20b that also projects outward from the cover member 20.

  Although not shown in FIG. 5, a similar recess 21 is provided on the left side surface of the cover member 20. That is, the recess 20 formed on the outer surface of the cover member 20 includes an arc shape included in the cover member 20 and is perpendicular to the optical axis of the light source unit 27 (perpendicular to the paper surface of FIG. 5). In the cross sectional view, at least one dent is formed on the left and right with the optical axis as the center.

  By making the side surface of the cover member 20 into such a shape, the user's hand H can easily grip the cover member 20 (see FIG. 2), and the cover member 20 can be easily detached from the main body unit 10. That is, by hooking a finger on a portion of the recess 21 (formed between the recess upper end portion 20a and the recess lower end portion 20b), the hand H holds the cover member 20, and a downward force is applied to the recess 21. The cover member 20 can be removed without sliding the finger.

  Further, from the viewpoint of ease of gripping, the shape of the side surface of the cover member 20 may be a tapered shape that narrows upward. However, if the tapered shape is narrowed upward, the concave upper end portion 20a does not protrude outward, and dust easily accumulates on the side surface of the cover member 20. However, the dent 21 is provided as in the lighting device 100 of the first embodiment, and the dent upper end portion 20a that protrudes outward from the cover member 20 and the dent lower end portion 20b that also protrudes outward are formed. 21 is less likely to accumulate dust.

  Furthermore, by providing the recess 21 on the side surface of the cover member 20, the surface area of the cover member 20 can be increased compared to the cover member 20 having a vertical side surface (a side surface without the recess 21) in the vertical direction. And the light emission area of the lighting fixture 100 will increase because the surface area of the cover member 20 increases.

  In particular, the effect of this increases when a light emitting body having high directivity such as an LED is used as the light source unit 27. Specifically, when the light source unit 27 is, for example, a highly directional LED, it is difficult for light to be directed in the left and right direction of the cover member 20, and the brightness tends to be insufficient in the vicinity of the left and right of the cover member 20. However, by providing the recess 21 on the side surface of the cover member 20, the surface area of the cover member 20, that is, the light emitting area of the lighting device 100 can be increased. In particular, since the surface area increases on the side surface of the cover member 20, sufficient brightness can be ensured even in the left-right direction that tends to be dark.

  Moreover, in the illuminating device 100 of this embodiment, the shape of the dent 21 is R shape. Therefore, since the dent 21 is constituted only by a curve, a soft impression is given to the user, and the design of the dent 21 is excellent. Further, since it is configured only by a curve, more uniform light can be emitted to the outside.

  In the illumination device 100 of the present embodiment, the shape of the recess 21 is an R shape as described above. However, the shape of the recess 21 is not limited to the shape of FIG. 5A, and may be, for example, the shapes shown in FIGS.

  For example, the dent may be a dent 21A having a cross-sectional shape shown in FIG. By adopting such a shape, the length of the inclined surface constituting the recess 21 can be ensured long, and the ease of gripping is further improved. Further, since the length of the inclined surface becomes longer, the surface area of the cover member 20A becomes larger, and the light emitting area becomes larger.

  Further, for example, the dent may be a dent 21 </ b> B in which the lower end 20 </ b> Bb protrudes outside the cover member 20 </ b> B from the upper end 20 </ b> Ba as shown in FIG. With such a shape, when the cover member 20B is gripped by the user, the finger is easily caught on the lower end portion 20Bb. Therefore, the user can easily remove the cover member 20B. Further, similarly to the cover member 20 shown in FIG. 5A, the cross-section has an arc shape, so that dust is less likely to accumulate.

  Furthermore, for example, the recess may be a recess 21C having a cross section like a trapezoidal upper base shown in FIG. By adopting such a shape, the light emitting area can be further increased and can be easily grasped, as in FIG. 5B.

  Further, for example, the recess may be a recess 21D having a shape like the trapezoidal chamfer described in FIG. 5D shown in FIG. By adopting such a shape, more uniform light can be emitted to the outside as in the case of the cover member 20 shown in FIG. Further, as in FIG. 5C, dust is less likely to accumulate.

  Further, for example, the recess is a recess in which the upper end portion 20Ea protrudes outside the cover member 20E from the lower end portion 20Eb, as opposed to the recess 21B illustrated in FIG. It may be 21E. By adopting such a shape, the upper end portion 20Ea protrudes further outward, and the cross section has an arc shape, so that the accumulation of dust in the recess 21E is more reliably prevented.

  Among these, the upper end of the dent (see FIG. 5 (a) in a cross-sectional view including a circular arc shape included in the cover member 20 and perpendicular to the optical axis of the light source unit 27 (direction perpendicular to the paper surface of FIG. 5). ), The line segment connecting the recess upper end 20a) and the recess lower end (in the figure, the recess lower end 20b) is parallel to the optical axis of the light source unit 27 (not shown in FIG. 5). Are preferred. Here, the optical axis refers to an axis of light emitted from the light source unit 27 and extends in the same direction as the direction in which the guide member 31 extends in FIG. Among the cover members shown in FIG. 5, as specific examples of preferable ones, the cover member 20 shown in FIG. 5 (a), the cover member 20A shown in FIG. 5 (b), and the cover shown in FIG. 5 (d). The member 20C is a cover member 20e shown in FIG. Thereby, it is possible to balance both ease of holding the cover member 20 and the like by the user and difficulty in depositing dust on the cover member 20 and the like in a balanced manner.

[2. Second Embodiment]
Next, the lighting fixture 200 of 2nd Embodiment is demonstrated, referring FIG.6 and FIG.7. Components similar to those of the above-described lighting fixture 100 are denoted by the same reference numerals, and detailed description thereof is omitted. Moreover, since the lighting fixture 200 of 2nd Embodiment has the structure similar to the said lighting fixture 100 fundamentally, a different point from the said lighting fixture 100 is mainly demonstrated in the following description.

  FIG. 6 is a diagram illustrating a state where the cover member 20F is removed from the main body unit 10A of the lighting fixture 200 of the second embodiment. In the luminaire 100 described above, the signal connection portion 16 is connected to the signal terminal block 22 independent of the main unit 10 and the cover member 20. However, in the lighting fixture 200 of the second embodiment, the signal terminal block 22 is fixed to the cover member 20F, and the signal line 11 and the signal line 29 are connected by the signal connectors 17 and 28. Yes.

  That is, in the lighting apparatus 200 of the second embodiment, the signal connector 17 is connected to the end of the signal line 11. Further, a signal line 29 connected to a signal connector 28 is connected to the signal terminal block 22. Here, the cover member 22 is fixed to the signal terminal block 22 as described above. By connecting the signal connector 17 and the signal connector 28, an electrical signal from a light control device (not shown) is transmitted to the lighting device 26 through the signal terminal block 22.

  FIG. 7 is a diagram showing a state in which the connection between the signal line 11 and the power supply line 14 on the main unit 10A side and the signal line 29 and the power supply line 25 on the cover member 20F side is released in the state of FIG. Although the description is omitted for the sake of simplicity, for example, when the cover member 20F is attached to the main unit 10A in the state of FIG. 7 after maintenance of the lighting fixture 200, the procedure described with reference to FIG. The same procedure can be applied.

  In the lighting fixture 200, unlike the lighting fixture 100, the signal terminal block 22 is fixed to the cover member 20F. Therefore, in order to connect the light control device and the lighting device 26, it is only necessary to connect the signal connector 17 and the signal connector 28, and electrical connection can be easily achieved. Moreover, since this connection can be performed in the vicinity of the main body cover 20F, as in the case of the lighting fixture 100, maintenance of the lighting fixture 200 and the like are facilitated.

  Further, since the signal terminal block 22 is fixed to the cover member 20F, when the signal line 29 is connected to the signal terminal block 22, the connection port of the signal terminal block 22 is easily visible. Thereby, workability when connecting the signal line 29 to the signal terminal block 22 is improved. Further, similarly to the above-described lighting fixture 100, the signal terminal block 22 is also independent of the main unit 10A in the lighting fixture 200, whereby the versatility of the main unit 10A can be enhanced.

[3. Third Embodiment]
Next, the lighting fixture 300 of 3rd Embodiment is demonstrated, referring FIG.8 and FIG.9. Components similar to those of the lighting fixtures 100 and 200 described above are denoted by the same reference numerals, and detailed description thereof is omitted. Moreover, since the lighting fixture 300 of 3rd Embodiment has the structure similar to the said lighting fixture 100,200, in the following description, a different point from the said lighting fixture 100,200 is mainly described. explain.

  FIG. 8 is a diagram illustrating a state in which the cover member 20G is removed from the main body unit 10B of the lighting fixture 300 of the third embodiment. In the luminaire 100 and the luminaire 200 described above, the connector for connecting the signal lines and the connector for connecting the power lines are separate. More specifically, for example, in the lighting fixture 100 shown in FIGS. 3 and 4, the signal connection portion 16 and the signal terminal block 22 are connected to connect the signal line 11 and the signal line 23. Further, in order to connect the power supply line 14 and the power supply line 25, the power supply connector 15 and the power supply connector 14 are connected. This also applies to the lighting fixture 200 shown in FIGS.

  However, in the luminaire 300 of the third embodiment, the signal line 11 and the power line 14 on the main unit 10B side are connected to one connector 18. On the other hand, the signal line 29 and the power supply line 25 on the cover member 20G side are connected to one connector 30. Therefore, by connecting the connector 18 and the connector 30, electrical connection between the signal lines and electrical connection between the power supply lines can be achieved.

  FIG. 9 is a diagram illustrating a state in which the connection between the signal line 11 and the power supply line 12 on the main unit 10B side and the signal line 29 and the power supply line 25 on the cover member 20G side is released in the state of FIG. For example, when the cover member 20G is attached to the main unit 10B in the state shown in FIG. 9 after maintenance of the lighting fixture 300, the signal line and the power line can be particularly easily electrically connected. Specifically, by connecting the connector 18 and the connector 30, these electrical connections can be performed collectively. Further, since this connection can be performed in the vicinity of the main body cover 20G, as in the case of the lighting fixture 100 and the lighting fixture 200, maintenance and the like of the lighting fixture 300 are facilitated.

  Further, since the signal terminal block 22 is fixed to the cover member 20G, the workability when the signal line 29 is connected to the signal terminal block 22 is improved as in the case of the lighting fixture 200 described above. Further, similarly to the lighting fixtures 100 and 200, the signal terminal block 22 is also independent of the main unit 10B in the lighting fixture 300, whereby the versatility of the main unit 10B can be enhanced. Further, unlike the lighting fixtures 100 and 200, one connector is sufficient, so the number of connectors can be reduced and the manufacturing cost of the lighting fixture 300 can be reduced.

[4. Modified example]
Although the present embodiment has been described with reference to the three embodiments, the present embodiment is not limited to the contents described above. Therefore, the present invention can be implemented by appropriately combining or modifying the above-described embodiments.

  For example, although the modification of the cover member 20 was described in the first embodiment, the modification of the cover member 20 is similarly applied to the lighting fixture 200 of the second embodiment and the lighting fixture 300 of the third embodiment. Is possible.

  Further, for example, the shape of the recess formed in the cover member 20 is not limited to that illustrated in FIG. 5, and may be any shape. In other words, for example, the side surface of the cover member 20 may be tapered so that the recess 21 is formed in the middle of the side surface. Further, the side surface of the cover member 20 (the surface formed between the recessed upper end portion 20a and the recessed lower end portion 20b) is not necessarily required. In this case, the recess 21 is formed on the surface of the cover member 20.

  Further, for example, in the cover member 20 shown in FIG. 1 and the like, the recess 21 is formed over the entire longitudinal direction (the recess 21 is not shown in FIG. 1), but the recess 21 is not necessarily formed over the entire region. There is no need to be formed, and the cover member 20 may be formed in a part in the longitudinal direction. Further, in the cover member 20, one recess 21 is formed on each of the left and right in a cross-sectional view in a direction perpendicular to the optical axis, but the recess 21 may be formed only in one of them. . Further, any number of the recesses 3 may be formed.

  Further, in the illustrated example, a rectangular light source unit 27 is used, and a rectangular shape when projected from below the main body unit 10 and the cover member 20 is used. The disc-shaped main unit 10 and the cover member 20 may be used.
