The elastic plate 42 of the pipe fixing bracket 40 has elasticity against a force (impact) acting in the axial direction of the bolt 60, that is, the plate thickness direction of the elastic plate 42.

  With the above configuration, for example, when an earthquake occurs, the pipe fixing bracket 40 (elasticity) is applied to an impact acting in a lateral direction (for example, the X-axis direction) perpendicular to the axis of the bolt 60 as shown in FIG. The impact can be absorbed by rotating the pipe 50 around the axis of the bolt 60 as the connecting portion (the direction indicated by the symbol A in FIG. 5) with respect to the plate 42).

  Further, as shown in FIG. 6, with respect to an impact acting laterally (for example, in the Y-axis direction) along the axial direction of the bolt 60, the elastic plate 42 is caused by the elasticity of the elastic plate 42 of the pipe fixture 40. The impact can be absorbed by bending (elastically deforming) the bolt 60 in the axial direction (the direction indicated by the symbol B in FIG. 6). That is, even when a shake occurs due to an earthquake, it is possible to absorb an impact in either the X-axis direction or the Y-axis direction, and it is possible to absorb an impact caused by vibration such as an earthquake. Further, the upper cover 20 and the lower cover 30 do not restrict the bending operation in the direction indicated by the symbol B.

  As shown in FIGS. 4 and 6, the pipe fixing bracket 40 includes elastic plates 42 and 42 as opposed portions facing each other with an end portion as one end of the pipe 50 as the second hanging portion interposed therebetween. . A shaft hole 43 and a shaft hole 51 through which the bolt 60 is inserted are formed at the ends of the elastic plates 42 and 42 and the pipe 50. Thereby, the pipe 50 can be rotated with respect to the pipe fixing bracket 40 around the axis of the bolt 60.

  Further, as shown in FIG. 6, a gap d is provided along the axial direction of the bolt 60 between the inner surface of the elastic plate 42 and the outer peripheral surface of the pipe 50. By providing the gap d along the axial direction of the bolt 60, the end of the pipe 50 can move along the axial direction until the end of the pipe 50 abuts against the elastic plate 42 and the movement is restricted. It is possible to further absorb the acting impact.

  As shown in FIGS. 3, 4, and 6, the mounting bracket 10 is formed by separating the insertion holes 11 through which the elastic plates 42 that face each other are inserted. The pipe fixing bracket 40 includes an opposing elastic plate 42 and a contact plate 41 that connects the elastic plates 42 and contacts the mounting bracket 10. With the mounting bracket 10 fixed to the ceiling surface, the elastic plate 42 is inserted into the insertion hole 11 from the upper side of the mounting bracket 10, the elastic plate 42 is suspended from the mounting bracket 10, and the contact plate 41 is moved to the upper side of the mounting bracket 10. It is fixed in contact with. Thereby, since the contact plate 41 of the pipe fixing bracket 40 is fixed on the upper side of the mounting bracket 10, it does not fall downward from the mounting bracket 10, and is strong against a vertical impact caused by vibration such as an earthquake. Can be given.

  Further, as shown in FIG. 4, the contact plate 41 of the pipe fixing bracket 40 is fixed to the mounting bracket 10 with screws 44, so that the contact plate 41 can be more firmly fixed to the mounting bracket 10. Further, the rigidity can be further increased against a longitudinal impact caused by vibration such as an earthquake.

  Further, as shown in FIG. 6, the upper cover 20 fixed to the mounting bracket 10 has a mode in which the bolt 60 is accommodated, and even if the bolt 60 is loosened and moves in the axial direction, the head of the bolt 60 is on the upper side. Since the movement of the bolt 60 in the axial direction is restricted by coming into contact with the inner peripheral surface of the cover 20, the bolt 60 is prevented from falling off the shaft holes 43 and 51 (the pipe fixing bracket 40 and the pipe 50). Thereby, it can prevent that the illuminating device main body 90 falls.

  Next, the experimental result about the earthquake resistance of the illuminating device 100 of this Embodiment is demonstrated. A steel frame frame having a length of 10 m, a width of 5 m, and a height of 3 m is created, and the steel frame frame is placed and fixed on the vibration table. The lighting device 100 of the present embodiment is attached to the top surface of the steel frame. The width direction is the X axis, the length direction is the Y axis, the height direction is the Z axis, and the input waveform is as follows: (1) El Centro wave with 300 gal in the X direction and 150 gal in the Z direction, (2) 600 gal in the X direction, Z An El Centro wave with a direction of 150 gal, (3) a HAGA wave with an X direction of 1300 gal and a Y direction of 1900 gal, respectively. As a result, it was confirmed that any of the above-described input waveforms does not cause an abnormality such as a drop or breakage of the lighting device 100, and has sufficient earthquake resistance by absorbing an impact caused by vibration such as an earthquake. .

  As described above, the lighting device 100 according to the present embodiment absorbs shocks caused by vibrations such as earthquakes and has seismic isolation, and has sufficient mounting strength with respect to mounting surfaces such as ceiling surfaces. The fall prevention can be realized.

  In the above-described embodiment, the pipe fixing bracket 40 has a U-shape, and is configured such that the opposing elastic plate 42 is inserted into the insertion hole 11 and the contact plate 41 is contacted with the mounting bracket 10 to be fixed. However, the configuration of the pipe fixing bracket 40 is not limited to this.

  For example, without forming the insertion hole 11 in the mounting bracket 10, the abutting plate 41 of the U-shaped pipe fixing bracket 40 is brought into contact with the lower side of the mounting bracket 10 and fixed with a screw or the like. The elastic body 42 of the pipe fixing bracket 40 may be suspended from the mounting bracket 10 in a state where 10 is mounted on the ceiling surface.

  In addition, the pipe fixing bracket 40 is not U-shaped, but two L-shaped pipe fixing brackets are prepared by extending an abutment plate and an elastic plate bent approximately 90 degrees from the end of the corresponding contacting plate. The elastic plate 42 of the pipe fixing bracket 40 may be suspended from the mounting bracket 10 in a state where the elastic plate of the pipe fixing bracket is inserted into the insertion hole of the mounting bracket 10 and the mounting bracket 10 is mounted on the ceiling surface.
