Specifically, the end member 22 is attached to the main body member 21 by screwing the screw 6 into the screw hole 21e and screwing the screw (not shown) into the screw hole 21f. . The end member 22 is formed with an insertion hole 22 a into which a support member for installation can be inserted at a position corresponding to the insertion hole 21 d of the main body member 21. For this reason, the insertion holes 22a and 21d constitute a hole penetrating the housing 2 in the longitudinal direction. Further, the end member 22 is formed with a protruding portion 22b protruding rearward (Y2 direction) on the main body member 21 side of the upper end surface.

  The end member 22 houses a connector 7 to which a power cable (not shown) for supplying power to the LED 1 can be connected. The connector 7 is connected to the LED 1 via the wiring board 3. For this reason, when the power cable is connected to the connector 7, power for turning on the LED 1 is supplied to the LED 1. The rear end surface of the end member 22 is cut away, and an opening 20 for exposing the connector 7 is formed in the rear end surface 2a of the housing 2. The opening 20 is provided to connect the power cable to the connector 7, and the connector 7 is arranged so that the insertion port faces the opening 20.

  That is, in the lighting device 100, two power supply connectors 7 are provided inside the housing 2, and the two connectors 7 are disposed at both ends in the longitudinal direction. Two openings 20 are provided so as to correspond to the connector 7, and the two openings 20 are arranged at both ends in the longitudinal direction.

  The two connectors 7 include a connector 7a on one side in the longitudinal direction (X1 direction side) and a connector 7b on the other side in the longitudinal direction (X2 direction side). The two openings 20 are configured by an opening 20a on one side in the longitudinal direction and an opening 20b on the other side in the longitudinal direction.

  And in the illuminating device 100 of this embodiment, the cover member 8 which opens and closes the opening part 20 is provided. The cover member 8 is inserted into a rail 21g (see FIG. 2) and is configured to be slidable in the longitudinal direction. The cover member 8 is formed so as to be shorter by one of the openings 20 than the length between the two openings 20, and the slidable distance is set to one of the openings 20. ing. Accordingly, the cover member 8 opens the opening 20a when the opening 20b (see FIG. 5) is closed as shown in FIG. 4, and the opening 20a (see FIG. 4) as shown in FIG. ) Is opened, the opening 20b is configured to be opened.

  The length between the two openings 20 is the length between the ends of the two openings 20 on the far side (outside). That is, in the present embodiment, the two openings 20 are each formed on one surface (surface on the Y2 direction side) of the plurality of surfaces of the lighting device 100, and the length between the two openings 20 is The length between the end of the opening 20a on the X1 direction side and the end of the opening 20b on the X2 direction side.

  Specifically, the cover member 8 includes two cover portions 81 that open and close the opening 20 and a connecting portion 82 that connects the two cover portions 81. The two cover portions 81 are configured by a cover portion 81a on one side in the longitudinal direction and a cover portion 81b on the other side in the longitudinal direction.

  The cover portion 81 is, for example, a metal plate-like member, and is formed so that the attachment portion 811, the guided portion 812, the stepped portion 813, and the cover plate 814 are continuous as shown in FIG. 3. .

  The attaching portion 811 is attached to the connecting portion 82 by, for example, a double-sided tape (not shown). The guided portion 812 is formed to have a length in the vertical direction (Z direction) larger than that of the mounting portion 811 and the stepped portion 813, and is guided by the rail 21g. The step portion 813 is formed so as to rise rearward (Y2 direction) from the guided portion 812. Note that the stepped portion 813 has a length in the vertical direction that is smaller than the distance between the pair of engaging portions 212g of the rail 21g. For this reason, the cover plate 814 is disposed rearward (Y2 direction side) of the rear end surface 2a of the housing 2 as shown in FIGS. The cover plate 814 has substantially the same length in the horizontal direction (X1 and X2 directions) as that of the end member 22, and the length in the vertical direction (Z direction) is equivalent to the protrusion 22b as compared to the housing 2. It has been made smaller. The cover plate 814 is configured to be able to open and close the opening 20, and a protruding portion 815 that protrudes upward is provided at the upper end portion.

  The connecting portion 82 is, for example, a resin plate member, and is formed to extend in the longitudinal direction. As shown in FIG. 3, the connecting portion 82 includes a plate-like portion 82 a and a protrusion 82 b that protrudes backward (Y2 direction) from the upper end portion and the lower end portion of the plate-like portion 82 a. That is, the connecting portion 82 is formed such that a groove recessed in the front side (Y1 direction side) extends in the longitudinal direction. And the attachment part 811 of the cover part 81 is attached to the back side of the plate-like part 82a between the pair of protrusions 82b, and the guided part 812 of the cover part 81 is adjacent to both longitudinal ends of the connecting part 82. Be placed.

  The plate-like portion 82a is slightly smaller in length in the vertical direction than the rail 21g, and is substantially the same as the guided portion 812. The length of the protrusion 82b in the thickness direction (Y1 and Y2 directions) is slightly smaller than the distance between the groove-like portion 211g of the rail 21g and the engaging portion 212g, and the plate-like portion 82a and the attachment portion 811 are provided. The total thickness is almost the same.

  In such an illuminating device 100, as shown in FIG. 4, when the cover member 8 is arranged on the other side in the longitudinal direction (X2 direction side), the protruding portion 815 of the cover portion 81a is the end member 22. The step portion 813 of the cover portion 81 b is brought into contact with the end member 22. At this time, the opening 20a is opened, and the opening 20b (see FIG. 5) is closed by the cover 81b. As a result, the power cable can be connected to the connector 7a and the power cable cannot be connected to the connector 7b (see FIG. 5). When the power cable is connected to the connector 7a from this state, the connected power cable interferes with the cover member 8, and the cover member 8 cannot be slid. Therefore, when the power cable is connected to the connector 7a, the opening 20b cannot be opened, and the power cable cannot be connected to the connector 7b.

  On the other hand, as shown in FIG. 5, when the cover member 8 is arranged on one side in the longitudinal direction (X1 direction side), the stepped portion 813 of the cover portion 81 a is brought into contact with the end member 22 to cover the cover. The protruding portion 815 of the portion 81 b is in contact with the protruding portion 22 b of the end member 22. At this time, the opening 20a (see FIG. 4) is closed by the cover 81a, and the opening 20b is opened. As a result, the power cable cannot be connected to the connector 7a (see FIG. 4), and the power cable can be connected to the connector 7b. When the power cable is connected to the connector 7b from this state, the connected power cable interferes with the cover member 8, and the cover member 8 cannot be slid. Therefore, when the power cable is connected to the connector 7b, the opening 20a cannot be opened, and the power cable cannot be connected to the connector 7a.

  In any case, the two openings 20 open in the same direction (Y2 direction), and the cover member 8 slides in the direction orthogonal to the opening direction (X1 and X2 directions) to open the opening 20a and the opening. One of the portions 20b is opened, so that the power cable can be connected to only one of the connector 7a and the connector 7b.

-Effect-
In the present embodiment, as described above, the cover member 8 selectively opens the two openings 20 so that the connector 7 to which the power cable can be connected can be selected from the two. When the power cable is connected to the connector 7 through the opened opening 20, the opening 20 corresponding to the other connector 7 is automatically closed by the cover member 8. It is possible to prevent the power cable from being connected to the connector 7. Therefore, when two connectors 7 are provided, it is possible to prevent a wiring error that a power cable is connected to both connectors 7.

  In addition, by providing two connectors 7, the power cable can be easily routed and deterioration in appearance can be suppressed. For example, when two lighting devices 100 are arranged linearly under a shelf between a pair of partition walls, the openings 20 on the sides adjacent to each other are closed and the openings 20 on the partition wall side are opened. Since the power cable can be wired along the partition wall by connecting the power cable, the power cable can be easily routed and the appearance can be prevented from deteriorating.

  In the present embodiment, the cover member 8 is formed so as to be shorter by one of the openings 20 than the length between the two openings 20, thereby forming the two openings 20 in the cover member 8. Can be easily opened alternatively.

  Further, in the present embodiment, the cover member 8 is configured by the two cover portions 81 and the connecting portion 82 that connects them, so that the cover portion can be provided for the illumination device 100 having different dimensions (length in the longitudinal direction). By sharing 81, it is possible to cope with the problem by changing the dimensions of the connecting portion 82. Moreover, since the cover part 81 and the connection part 82 can be made of different materials, the connection part 82 is made of resin, and the manufacturing cost can be reduced.
