FIG. 15 shows a state in which the shaft member 331c shown in FIG. 14 is slid and moved in a direction opposite to the X direction. By sliding the shaft member 331c in the direction opposite to the X direction, the distance between the end portion 331b2 of the cover mounting portion 330 and the design surface portion 111A is widened in the X direction. As a result, the cover 30 can be rotated as shown in FIG. Then, the light source unit 20 can be exposed by rotating the cover 30. When the light source unit 20 is housed in the cover 30, the operations described with reference to FIGS. 13 to 15 may be performed in the reverse order. When the cover 30 is removed from the luminaire 10, the shaft member 331c is moved in the order of the slit Sr3 and the slit Sr4. As a result, the shaft member 331c can be removed from the slit portion 114a, and the cover 30 can be removed from the luminaire 10.

<Effect of Embodiment 1>
Next, the effect of the first embodiment will be described. The cover 30 is rotatably held by the luminaire 10. Therefore, when the maintenance work of the lighting device 1 is performed, the cover 30 does not fall off from the lighting fixture 10 even if the operator rotates the cover 30 to expose the light source unit 20. That is, the operator can perform maintenance work such as attaching / detaching the light source unit 20 without removing the cover 30 from the lighting fixture 10. Therefore, in the lighting device 1, the burden of maintenance work that requires opening of the cover 30 is suppressed. Further, since the lighting device 1 is installed in a high place such as the ceiling of a building, a stepladder is used, for example, during maintenance work of the lighting device 1.

Further, the luminaire 10 is provided on the side surface portion 112 and has a receiving portion 114 that holds the shaft member 331c when the cover 30 rotates. As described above, since the lighting device 1 includes the shaft member 331c and the receiving portion 114, the operator can rotate the cover 30 to easily expose the light source unit 20.

The slit portion 114a of the receiving portion 114 has a slit Sr1 and a slit Sr2. Here, as shown in FIG. 13, when the shaft member 331c is located at the upper end of the slit Sr1, the cover 30 is among the one side surface portion 111 of the pair of side surface portions 111 and the pair of side surface portions 111. It is arranged between the other side surface portion 111 of the. Therefore, in the state shown in FIG. 13, the cover 30 can cover the area between one side surface portion 111 and the other side surface portion 111. Therefore, in the state shown in FIG. 13, the cover 30 can avoid the exposure of the light source unit 20 and the main body 120, and can more reliably protect the light source unit 20 and the main body 120. Further, when the shaft member 331c is located at the upper end of the slit Sr1, the cover 30 is inserted inside the frame-shaped member 110A. Therefore, in the state shown in FIG. 13, it is possible to prevent the light source unit 20 and the main body portion 120 from being exposed from between the cover 30 and the design surface portion 111A. That is, the design of the lighting device 1 is improved.

When the shaft member 331c slides to the lower end of the slit Sr1, the cover 30 separates from the luminaire 10 by the amount of the slide movement. That is, when the shaft member 331c is located at the lower end of the slit Sr1, the cover 30 is arranged below the side surface portion 111. Therefore, as shown in FIG. 14, the shaft member 331c slides to the lower end of the slit Sr1, so that the cover 30 and the design surface portion 111A are less likely to interfere with each other when the cover 30 is moved. Further, as shown in FIG. 15, the shaft member 331c slides to the end of the slit Sr2 of the receiving portion 114 which is connected to the slit Sr3, so that when the cover 30 is moved, the cover mounting portion 330 The end portion 331b2 and the design surface portion 111A are less likely to interfere with each other. As described above, since the lighting device 1 has a configuration in which the shaft member 331c is slid and moved, the lighting device 1 has an effect of more reliably protecting the light source unit 20 and the main body 120 and an effect of improving the design. Not only has it, but it also has the effect of suppressing interference between the cover 30 and the lighting fixture 10 and interference between the cover mounting portion 330 and the lighting fixture 10 when the cover 30 is moved.

Even if the slit portion 114a does not have the slit Sr2, the cover 30 can be rotated by changing the shape of the cover mounting portion 330. Specifically, in the state shown in FIG. 14, it is preferable that the end portion 331b2 has, for example, a concave shape so that the end portion 331b2 does not interfere with the design surface portion 111A. Thereby, even if the cover 30 is rotated in the state shown in FIG. 14, it is possible to prevent the end portion 331b2 from interfering with the design surface portion 111A.

The cover mounting portion 330 of the lighting device 1 is supported by the support portion 113. Therefore, it is possible to prevent the cover 30 from moving downward in the state shown in FIG.

The luminaire 10 has a gap 11 formed inside the frame-shaped member 110A and outside the main body 120. Further, in a state where the cover 30 accommodates the light source unit 20, the upper end portion of the cover 30 is inserted into the gap 11. As the upper end of the cover 30 is inserted into the gap 11, the cover 30 penetrates deeply into the luminaire 10. Therefore, the cover 30 can more reliably accommodate the light source unit 20 and the main body 120, and the lighting device 1 can more reliably protect the light source unit 20 and the main body 120. Further, since the upper end portion of the cover 30 is inserted into the gap 11, the gap 11 is filled by the cover 30. Therefore, it is possible to prevent the internal structure of the lighting device 1 from being exposed through the gap 11. That is, the design of the lighting device 1 is improved.

A metal supported portion 331, which is a member separate from the cover 30, is held by the luminaire 10. Therefore, when the cover 30 or the like vibrates, the metal supported portion 331 slides with the luminaire 10. Since the supported portion 331 is made of metal rather than resin, it is not easily broken, and the supported portion 331 is not easily damaged even if it slides on the lighting fixture 10.

Since the reinforcing member 340 is provided on the inner surface Srf1 of the cover 30, the reinforcing member 340 is obscured by the cover 30 in a state where the cover 30 is attached to the lighting fixture 10. Therefore, the design of the lighting device 1 is improved.

The reinforcing member 340 is connected to the supported portion 331. As a result, the reinforcing member 340 and the supported portion 331 are supported by each other, and even if vibration or the like is applied to the cover 30, damage to the cover 30 is suppressed. For example, when a projectile hits the surface portion 320 and the surface portion 320 is about to be displaced, the supported portion 331 of the surface portion 320 is connected to the reinforcing member 340, so that the displacement of the surface portion 320 is hindered by the reinforcing member 340 and the cover is covered. The damage of 30 is suppressed. Further, for example, when a projectile hits the surface portion 310B and the surface portion 320 tries to be displaced, the reinforcing member 340 of the surface portion 310B is connected to the supported portion 331, so that the displacement of the surface portion 310B is caused by the displacement or the like of the supported portion 331. This prevents the cover 30 from being damaged. Further, even if the cover 30 tries to heat-shrink, the displacement of the face portion 320 and the displacement of the face portion 310B are hindered, and as a result, the heat shrinkage of the cover 30 is suppressed.

The face portion 320 is sandwiched between the reinforcing member 340 and the supported portion 331. That is, a part of the reinforcing member 340 and a part of the supported portion 331 face each other via the surface portion 320. As a result, the effect of the reinforcing member 340 and the supported portion 331 supporting each other is further enhanced. That is, even if vibration or the like is applied to the cover 30, damage to the cover 30 is further suppressed. For example, when a projectile hits the surface portion 320 and the surface portion 320 tends to be displaced in the Y direction, the supported portion 331 also tends to be displaced in the Y direction together with the surface portion 320. At this time, since a part of the reinforcing member 340 and a part of the supported portion 331 face each other via the surface portion 320, when the supported portion 331 tries to be displaced in the Y direction, the supported portion 331 causes the surface portion 320. It is pushed back to the reinforcing member 340 through the displacement, and the displacement in the Y direction is further hindered. As a result, damage to the cover 30 is further suppressed. Further, for example, when the projectile hits the surface portion 310B and the surface portion 310B tries to be displaced in the Y direction, the reinforcing member 340 also tries to be displaced in the Y direction together with the surface portion 310B. At this time, since a part of the reinforcing member 340 and a part of the supported portion 331 face each other via the surface portion 320, when the reinforcing member 340 tries to be displaced in the Y direction, the reinforcing member 340 passes through the surface portion 320. It is pushed back to the supported portion 331, and the displacement in the Y direction is further hindered. As a result, damage to the cover 30 is further suppressed. Further, even if the cover 30 tries to heat-shrink, the displacement of the surface portion 320 and the displacement of the face portion 310B are further hindered, and as a result, the heat shrinkage of the cover 30 is further suppressed.

The end portion 340C of each reinforcing member 340 is connected to the supported portion 331 of one of the surface portions 320 of the pair of surface portions 320. Further, the end portion 340D of each reinforcing member 340 is connected to the supported portion 331 of the other face portion 320 of the pair of face portions 320. Therefore, as shown in FIG. 3, the combined shape of the pair of reinforcing members 340 and the pair of supported portions 331 is annular. Therefore, it is possible to prevent the effect of suppressing the breakage of the cover 30 and the effect of suppressing the heat shrinkage of the cover 30 from being dispersed in the circumferential direction of the cover 30.

The supported portion 331 is arranged inside the frame-shaped member 110A. Therefore, the supported portion 331 is less likely to be exposed, and the design of the lighting device 1 is improved.

The cover 30 is not an integrally molded resin member, but the face portion 320 and the main cover portion 310 are separately molded resin members. Then, the face portion 320 and the main cover portion 310 are welded or adhered and fixed. Therefore, if the cover 30 does not include the reinforcing member 340, the welded portion or the bonded portion between the surface portion 320 and the main cover portion 310 is likely to be peeled off by that amount. However, the lighting device 1 includes a reinforcing member 340. In addition, the face portion 320 is sandwiched between the reinforcing member 340 and the supported portion 331, and the reinforcing member 340 is connected to the supported portion 331. Therefore, when vibration or the like is applied to the lighting device 1 or when the cover 30 is thermally shrunk, the displacement of the surface portion 320 or the like is suppressed as described above. Therefore, peeling of the welded portion or the bonded portion between the surface portion 320 and the main cover portion 310 is suppressed.

Further, in the state shown in FIG. 24, the cover 1030 is arranged below the side surface portion 1112. Therefore, in the state shown in FIG. 24, even if the cover 1030 is moved in parallel in the Y direction, it is possible to prevent the surface portion 1320 of the cover 1030 from interfering with the side surface portion 1112. Here, when the cover 1030 is rotated in the state shown in FIG. 24, the surface portion 1310B and the side surface portion 1410 interfere with each other, and the light source unit 1020 is not exposed. Therefore, as will be described next, the shaft member 1331c is slid and moved from the lower end of the slit Sr11 to the lower end of the slit Sr12.

FIG. 26 shows the lighting device 1000 in a state where the shaft member 1331c is located at the end of the slit Sr12 connected to the slit Sr13. FIG. 27 is a diagram showing a state in which the shaft member 1331c is located at the end of the slit Sr12 that is connected to the slit Sr13. FIG. 26 shows a state in which the shaft member 1331c is slid from the lower end of the slit Sr11 to the lower end of the slit Sr12. By sliding the shaft member 1331c from the position shown in FIG. 25 to the position shown in FIG. 26, the distance between the surface portion 1310B and the side surface portion 1410 in the Y direction is widened. As a result, the cover 1030 can be rotated as shown in FIG. 26. Then, the light source unit 1020 can be exposed by rotating the cover 1030. When the cover 1030 is removed from the lighting fixture 1010, the shaft member 1331c is moved in the order of the slit Sr13 and the slit Sr14. As a result, the shaft member 1331c can be removed from the slit portion 1114a, and the cover 1030 can be removed from the lighting fixture 1010.

<Effect of Embodiment 2>
Next, the effect of the second embodiment will be described. The second embodiment has the following effects in addition to having the same effects as those of the first embodiment. The slit portion 1114a of the receiving portion 1114 has a slit Sr10. Further, when the shaft member 1331c is located in the slit Sr10 and the equipment cover 1400 is attached to the luminaire main body 1110, the lower surface portion 1310A of the cover 1030 is located above the design surface portion 1400A of the equipment cover 1400. ing. Therefore, even if the cover 1030 is to be rotated in the state where the lighting device 1000 is used, that is, in the state shown in FIG. 21, the cover 1030 interferes with the design surface portion 1400A of the equipment cover 1400. Therefore, it is possible to prevent the cover 1030 from rotating and exposing the light source unit 1020 when the lighting device 1000 is used.
