A first lamp 522 whose irradiation direction can be freely changed can be attached to the duct rail 52. Therefore, according to the lighting fixture 1 according to the present embodiment, it is possible to irradiate light in all directions such as the ceiling C, the floor surface, and the wall surface.

Further, in the present embodiment, the second projecting portion 424 projects in a direction orthogonal to the surface direction of the base portion 421. As a result, the movement of the instrument body 5 in the left-right direction is further restricted. As a result, the instrument main body 5 is stably temporarily suspended by the hanging metal fitting 3.

Further, in the present embodiment, the support hole 411 is arranged at substantially the center (including the center) of the first side wall 32 in the front-rear direction. As a result, the instrument main body 5 is stably temporarily suspended from the hanging metal fitting 3.

In the present embodiment, the case where the support portion 41 is provided on the hanging metal fitting 3 and the hook portion 422 is provided on the instrument main body 5 has been described as an example, but the support portion 41 is provided on the instrument main body 5 and the hooking member. 42 may be provided in the hanging metal fitting 3.

Further, in the present embodiment, the case where the support hole 411 is arranged substantially at the center (including the center) of the first side wall 32 in the vertical direction has been described as an example, but the support hole 411 is the center of the first side wall 32. It may be placed above. By arranging the support hole 411 at substantially the center of the first side wall 32 in the vertical direction or above the center, the instrument main body 5 is temporarily suspended from the hanging metal fitting 3 more stably.

Further, in the present embodiment, the configuration in which the second protruding portion 424 protrudes downward from the first protruding portion 423 has been described, but the second protruding portion 424 protrudes upward from the first protruding portion 423. May be good.

Further, in the present embodiment, the case where the number of hook portions 422 is one has been described as an example, but the number of hook portions 422 may be a plurality. For example, the number of hooking members 42 may be plural. It is preferable that the plurality of hook portions 422 are evenly arranged in the front-rear direction of the instrument main body 5. As a result, the instrument main body 5 is temporarily suspended on the hanging metal fitting 3 more stably. The number of support holes 411 may be changed according to the number of hook portions 422. Alternatively, the support hole 411 may be changed in size so that a plurality of hook portions 422 can be inserted.

Further, in the present embodiment, the support hole 411 penetrates the first side wall 32, but the support hole 411 does not have to penetrate the first side wall 32.

A cable connected to the hood-in cap 521 arranged at the right end of the first instrument main body 5a is inserted into the second cable insertion hole h2 of the second side wall 33. Each cable inserted into the first cable insertion hole h1 and the second cable insertion hole h2 of the second side wall 33 is a second instrument via the first cable insertion hole h1 and the second cable insertion hole h2 of the first side wall 32. It is guided to the main body 5b.

Subsequently, the configuration of the L-shaped hanging metal fitting 3L according to the second embodiment will be described with reference to FIG. FIG. 12 is a perspective view showing the configuration of the L-shaped hanging metal fitting 3L according to the second embodiment.

As shown in FIG. 12, the L-shaped hanging bracket 3L has an upper wall 31, a first side wall 32, a third side wall 35, and a lower wall 34. The first side wall 32 and the third side wall 35 are orthogonal to each other. The first side wall 32 faces the second instrument main body 5b described with reference to FIG. Further, the third side wall 35 faces the third instrument main body 5c described with reference to FIG. 10. In the present embodiment, the side surface of the L-shaped hanging bracket 3L facing the first side wall 32 and the side surface facing the third side wall 35 are open.

The L-shaped hanging bracket 3L is different from the intermediate hanging bracket 3M in that it has a third side wall 35 instead of the second side wall 33. The third side wall 35 has the same configuration as the first side wall 32. Specifically, the support portion 41 is provided on the third side wall 35. The hook portion 422 on the front side of the third instrument main body 5c described with reference to FIG. 10 is inserted into the support hole 411 of the support portion 41 provided in the third side wall 35. The hook portion 422 on the right side of the second instrument main body 5b is inserted into the support hole 411 of the support portion 41 provided in the first side wall 32.

Further, a first cable insertion hole h1 and a second cable insertion hole h2 are formed in the third side wall 35. A cable connected to the second power supply unit of the second lamp 54 of the second fixture main body 5b is inserted into the first cable insertion hole h1 of the first side wall 32. A cable connected to the hood-in cap 521 of the second instrument main body 5b is inserted into the second cable insertion hole h2 of the first side wall 32. Each cable inserted into the first cable insertion hole h1 and the second cable insertion hole h2 of the first side wall 32 is a third instrument via the first cable insertion hole h1 and the second cable insertion hole h2 of the third side wall 35. It is guided to the main body 5c.

The second embodiment has been described above. In the case of a general wire hanging type luminaire, both ends in the longitudinal direction of the luminaire body are connected to the wire. In such a configuration, when a plurality of instrument bodies are connected, the pitch of the wires (the distance between the wires) is not uniform. On the other hand, in the lighting fixture 1 according to the present embodiment, a plurality of fixture main bodies 5 are connected via a hanging metal fitting 3 suspended from a wire 2. Therefore, according to the present embodiment, as shown in FIG. 10, the pitch of the wires can be kept constant even when a plurality of instrument main bodies 5 are connected. In addition, the number of wires can be reduced as compared with the case where both ends in the longitudinal direction of the instrument body are connected to the wires.

The embodiments of the present invention have been described above with reference to the drawings (FIGS. 1 to 12). However, the present invention is not limited to the above-described embodiment, and can be implemented in various aspects without departing from the gist thereof. Further, the numerical values shown in the above embodiments, the materials of each component, and the like are merely examples and are not particularly limited, and various changes can be made without substantially deviating from the effects of the present invention. ..

For example, in the embodiment of the present invention, the mode in which the duct rail 52 is arranged in the first space A1 has been described, but the duct rail 52 may not be arranged in the first space A1. Alternatively, in the first space A1, instead of the duct rail 52, for example, a lamp similar to the second lamp 54 arranged in the second space A2 may be arranged.
