The optical member 54 shown in FIG. 2 is a translucent member into which light from the reflecting member 52 is incident. The optical member 54 may have a function of controlling and emitting the light distribution of the light incident from the reflecting member 52.

[2. Action and Effect]
The operation and effect of the lighting fixture 10 according to the present embodiment will be described.

  In the present embodiment, in a state in which the elastic body 40 is attached to the fixed frame 30, the biasing portion 41 of the elastic body 40 is directed from the positive direction to the negative direction in the Z-axis direction of FIGS. The shape of the elastic body 40 is designed so as to be biased. That is, when the elastic body 40 is attached to the fixed frame 30, the shape of the elastic body 40 is designed so that the urging portion 41 of the elastic body 40 is deformed from a negative direction toward the positive direction in the Z-axis direction. The In other words, the bending angle of the bending portion 43 in the elastic body 40 alone is smaller than the bending angle of the bending portion 43 in a state where the elastic body 40 is attached to the fixed frame 30. In this way, the elastic body 40 urges the rotation frame 28 toward the restriction portion 31 of the fixed frame 30, and the rotation frame 28 is rotated by holding the rotation frame 28 with the fixed frame 30. The force required to make it increase. Specifically, a frictional force between the rotation frame 28 and the elastic body 40 is generated. Furthermore, the frictional force between the auxiliary reflection member 56 that rotates integrally with the rotation frame 28 and the fixed frame 30 increases. For this reason, it can suppress that the rotation frame 28 rotates with the vibration of a construction material, etc. Therefore, it can suppress that the instrument main body 20 supported by the rotation frame 28 rotates with respect to the construction material 900. FIG.

  Moreover, the elastic body 40 can be manufactured easily and at low cost by using a wire. In the present embodiment, the wire forming the elastic body 40 has a circular cross section. Thereby, the contact part with the rotation frame 28 in the urging | biasing part 41 of the elastic body 40 can be formed in the surface which has a curvature. That is, the elastic body 40 can be formed so that there is no angular portion at the contact portion of the biasing portion 41 with the rotating frame 28. For this reason, even when minute irregularities exist on the surface of the rotating frame 28, it is possible to suppress the elastic body 40 from being caught on the surface of the rotating frame 28. Even when the wire has a circular cross section, there may be an angular portion at the longitudinal end of the wire, and therefore the longitudinal end of the wire is disposed at the biasing portion 41. In this case, the end portion can be caught on the surface of the rotation frame 28. Therefore, you may form the elastic body 40 so that the longitudinal direction edge part of a wire may not be arrange | positioned at the urging | biasing part 41 of the elastic body 40. FIG. In this Embodiment, as FIG. 6 shows, the two longitudinal direction edge parts of a wire are arrange | positioned at the attaching part 45, and are not arrange | positioned at the urging | biasing part 41. As shown in FIG.

  In the present embodiment, the fixed frame 30, the rotation frame 28, and the elastic body 40 have conductivity. Here, the fixed frame 30 may be provided with an electrically insulating coating. An electrically insulating auxiliary reflecting member 56 is disposed between the fixed frame 30 and the rotating frame 28. For this reason, the fixed frame 30 and the rotation frame 28 are not necessarily directly connected. However, in the present embodiment, the fixed frame 30 can be electrically connected to the rotating frame 28 via the elastic body 40. Specifically, the elastic body 40 is electrically connected to the fixed frame 30 via a conductive mounting screw 48 screwed into the fixed frame 30. Further, the elastic body 40 is electrically connected to the rotating frame 28 at the urging portion 41. For this reason, the fixed frame 30 can be grounded by grounding the rotating frame 28. In addition, when the elastic body 40 is electrically connected to the rotating frame 28 in the urging portion 41, the urging portion 41 urges the rotating frame 28. Conduction can be made more reliable.

  The elastic body 40 is attached to the fixed frame 30 by a conductive attachment screw 48 screwed into a screw hole 30 s formed in the fixed frame 30. Thereby, the elastic body 40 can be attached to the fixed frame 30 and can be electrically connected to the fixed frame 30. In addition, when the mounting screw 48 is screwed into the screw hole 30 s formed in the fixed frame 30, the fixing frame 30 and the mounting screw 48 can be attached even when the surface of the fixed frame 30 is electrically insulated. It can be easily conducted. That is, the fixed frame 30 and the elastic body 40 can be easily conducted through the mounting screw 48.

  Furthermore, when the lighting fixture 10 includes a conductive leaf spring 80 that is electrically connected to the fixed frame 30, the leaf spring 80 can also be grounded. Therefore, by grounding the rotating frame 28, not only charging of the rotating frame 28 but also charging of the fixed frame 30 and the leaf spring 80 can be suppressed. In the present embodiment, the instrument body 20 and the connection member 26 are conductive. The instrument body 20 has a configuration for connecting a ground wire. This configuration will be described with reference to the drawings.

  FIG. 7 is a top view illustrating an appearance of the lighting fixture 10 according to the present embodiment.

  As shown in FIG. 7, the mounting base 22 of the instrument body 20 has a ground portion 25 to which a ground wire is connected. More specifically, a screw is screwed into a screw hole formed on the outer surface of the mounting base 22. With this screw, the terminal to which the ground wire is connected can be electrically connected to the mounting base 22. Thereby, the instrument main body 20 (that is, the mounting base 22 and the cylindrical member 24 electrically connected to the mounting base 22) can be grounded. In addition, the instrument main body 20 and the connection member 26 are electrically connected directly or indirectly via the screw 32. Furthermore, the connection member 26 and the rotation frame 28 are electrically connected directly or indirectly via a bolt 34. That is, the rotation frame 28 is grounded via the connection member 26 and the instrument body 20. Thereby, the fixed frame 30 can be grounded via the rotating frame 28 and the elastic body 40.

And the frictional force between the elastic body 40 and the like increases. Thereby, it can suppress that the rotation frame 28 rotates with the vibration of the construction material 900, etc. FIG. Therefore, it can suppress that the instrument main body 20 supported by the rotation frame 28 rotates with respect to the construction material 900. FIG. Moreover, the elastic body 40 can be manufactured easily and at low cost by forming the elastic body 40 with a wire.

  In the lighting fixture 10, the fixed frame 30, the rotation frame 28, and the elastic body 40 may be formed of a conductive member, and the fixed frame 30 may be electrically connected to the rotation frame 28 via the elastic body 40.

  Thereby, the fixed frame 30 can also be grounded by grounding the rotating frame 28.

  In the lighting apparatus 10, the elastic body 40 may be electrically connected to the rotation frame 28 in the urging portion 41.

  In this case, since the urging portion 41 urges the rotating frame 28, the urging portion 41 and the rotating frame 28 can be more reliably connected.

  Further, in the lighting fixture 10, the fixture body 20 may be formed of a conductive member and include a ground portion 25 to which a ground wire is connected, and the rotating frame 28 may be electrically connected to the fixture body 20.

  Thereby, the instrument main body 20 can be grounded. In addition, since the instrument body 20 and the rotation frame 28 are electrically connected, the fixed frame 30 can be grounded via the rotation frame 28 and the instrument body 20.

  The lighting fixture 10 may further include a plate spring 80 attached to the fixed frame 30 and formed of a conductive member, and the plate spring 80 may be electrically connected to the fixed frame 30.

  Accordingly, the leaf spring 80 can be grounded by grounding the rotation frame 28.

  Further, in the lighting fixture 10, the elastic body 40 may be attached to the fixed frame 30 by an attachment screw 48 screwed into a screw hole 30 s formed in the fixed frame 30.

  Thereby, the elastic body 40 can be attached to the fixed frame 30 and can be electrically connected to the fixed frame 30. In addition, when the mounting screw 48 is screwed into the screw hole 30 s formed in the fixed frame 30, the fixing frame 30 and the mounting screw 48 can be attached even when the surface of the fixed frame 30 is electrically insulated. It can be easily conducted. That is, the fixed frame 30 and the elastic body 40 can be easily conducted through the mounting screw 48.

  Moreover, in the lighting fixture 10, a wire may have a circular cross section.

  Thereby, the contact part with the rotation frame 28 in the urging | biasing part 41 of the elastic body 40 can be formed in the surface which has a curvature. For this reason, it can suppress that the elastic body 40 is caught in the rotation frame 28. FIG.

As mentioned above, although the lighting fixture which concerns on this invention was demonstrated based on embodiment, this invention is not limited to the said embodiment.

  For example, in the above embodiment, the elastic body 40 has a function of electrically connecting the fixed frame 30 and the rotation frame 28, but the configuration of the elastic body 40 is not limited to this. For example, the elastic body 40 may be formed of an electrically insulating member.

  It is also possible to use the elastic body 40 as a stopper for limiting the range of the pivotable angle of the pivot frame 28. For example, by providing the rotation frame 28 with a restraining member that stops the rotation of the rotation frame 28 by contacting the elastic body 40 at a predetermined rotation angle, the range of the rotation angle of the rotation frame 28 is provided. Can be limited to a range in which the restraining member does not contact the elastic body 40.

  Further, the auxiliary reflection member 56 of the lighting fixture 10 has a configuration that rotates integrally with the rotation frame 28, but the auxiliary reflection member 56 does not necessarily rotate integrally with the rotation frame 28. .

  Moreover, as long as the electroconductive component of the lighting fixture 10 can ensure the electrical continuity between each component, the surface may be provided with the electrically insulating coating.

  In the above embodiment, the light source 50 has the COB structure in which the LED chip is directly mounted on the base. However, the present invention is not limited to this. For example, an LED module having an SMD (Surface Mount Device) structure may be used in place of the LED module having a COB structure. An LED module having an SMD structure is a package type LED element in which an LED chip (light emitting element) is mounted in a recess of a resin package (container) and a sealing member (phosphor-containing resin) is enclosed in the recess. One or a plurality of (SMD type LED elements) is mounted on a substrate.

  In each of the above embodiments, the LED is exemplified as the light emitting element. However, as the light emitting element, a semiconductor light emitting element such as a semiconductor laser, or other solid light emitting elements such as an organic EL (Electro Luminescence) element or an inorganic EL. An element may be used.

  Moreover, the lighting fixture 10 in said embodiment may be attached to construction materials other than a ceiling.

  In addition, it is realized by arbitrarily combining the components and functions in each embodiment without departing from the scope of the present invention, and forms obtained by making various modifications conceived by those skilled in the art to each embodiment. Forms are also included in the present invention.
