FIG. 12 is an A-cross-sectional view of the decorative frame 220 shown in FIG. 7.

The lighting fixture 200 has a main body frame 210 and a decorative frame 220. The main body frame 210 is attached to the attached portion by a fixing tool. The decorative frame 220 is attached to the main body frame 210 so as to cover a part of the main body frame 210.

The main body frame 210 includes a main body surface 211 having a substantially square plate shape, and a main body side surface 212 projecting from the side side of the main body surface 211.
The main body surface 211 has a first region 213 provided on the central side and a second region 214 provided on the outer periphery of the first region 213.
The main body surface 211 is formed with an electric wire hole 211a for drawing an electric wire from the outside of the lighting device 1 and a mounting hole 211b through which a fixture for fixing the main body frame 210 to the attached portion is inserted.

The first region 213 is a range facing the frame 120 of the light source unit 100 in a state where the light source unit 100 is attached to the instrument main body 200. The first region 213 is a range surrounded by the virtual dotted line A in FIG. 8, and is a range having a substantially square shape like the frame 200. The first region 213 is provided with an electric wire hole 211a near the center.

The second region 214 is a range provided outside the first region 213, and is provided so as to surround the first region 213. The second region 214 is a range from the boundary line of the first region 213 indicated by the virtual dotted line A to the side surface 212 of the main body.

The second region 214 is provided with a plurality of mounting holes 211b. The mounting hole 211b is formed in an elongated hole shape, and is arranged so that the longitudinal direction of the elongated hole is orthogonal to the mounting hole 211b facing the first region 213. By providing the mounting holes 211b in this way, even if the arrangement of the fixture is slightly different from the predetermined position, the fixture body 210 can be mounted without applying a load.

The arrangement of the plurality of mounting holes 211b provided in the second region 214 will be described with reference to FIG. In FIG. 9, the interval facing each other across the first region 213 is defined as the interval A, and the interval facing each other without sandwiching the first region 213 is defined as the interval B.
The second region 214 is provided with mounting holes 211b so as to accommodate four different mounting intervals. It should be noted that the intervals A facing each other across the first region 213 are all formed to be the same.
The first mounting interval P1 is formed by two mounting holes 211b that sandwich the power supply hole 211a of the frame mounting portion 121.

The interval B of the fourth mounting interval P4 is the interval B4.
The interval B4 may be formed smaller than the interval B2. Alternatively, the value may be larger than the interval B2 and smaller than the interval B3.

By providing the fourth mounting interval P4 in this way, it is possible to suppress the influence on the strength of the main body frame 210 and provide a plurality of mounting holes 211b. This can prevent the strength from deteriorating due to the centralized mounting holes 211b penetrating the main body surface 211 in a part of the main body frame 210. Further, when the distance B dimension of the mounting holes 211b is close to each other, it is possible to prevent the mounting holes 211b from interfering with each other by providing the mounting holes 211b so that the distances A are orthogonal to each other. Even if they do not intersect vertically, the same effect can be obtained as long as the mounting holes 211b intersect at an angle that does not interfere with each other.

By providing a plurality of mounting holes 211b as shown in FIG. 9, the second region 214 can correspond to the arrangement interval of the plurality of fixtures, and the workability of the lighting device 1 can be improved. For example, in the replacement of an existing lighting fixture, the existing fixture can be used without being removed, and the work of installing a new fixture can be reduced. Further, when there is an obstacle on the back side of the mounted portion, for example, the back side of the ceiling and the fixture cannot be provided at a predetermined interval, the fixture can be provided by changing the arrangement interval of the fixture.

Embodiment 2.
Next, the lighting device of the second embodiment will be described with reference to FIGS. 15 to 17. The lighting fixture 500 according to the present embodiment has a main body frame 510 different from the lighting fixture 200 of the first embodiment. The same or corresponding parts as those in the first embodiment are designated by the same number, and duplicated description will be omitted.
FIG. 15 is a perspective view of the lighting device 400 according to the present embodiment. FIG. 16 is an exploded perspective view of the luminaire 500 shown in FIG. FIG. 17 is a plan view of the main body frame 510 shown in FIG. 16 as viewed from below.

The lighting device 400 includes a light source unit 100 and a lighting fixture 500 to which the light source unit 100 is detachably attached. The lighting fixture 500 has a main body frame 510 and a decorative frame 220.

The main body frame 510 includes a rectangular plate-shaped main body surface 511 and a main body side surface 512 projecting from the side side of the main body surface 511.
The main body surface 511 has a first region 513 provided on the central side and a second region 514 provided on the outer periphery of the first region 513.

The first region 513 is a range facing the frame 120 of the light source unit 100 in a state where the light source unit 100 is attached to the instrument main body 200. The first region 513 is a range surrounded by the virtual dotted line B in FIG. 17, and is a range having a substantially square shape like the frame 200.

The second region 514 is a range provided outside the first region 513, and is provided so as to surround the first region 513. The second region 514 is a range from the boundary line of the first region 513 shown by the virtual dotted line B to the side surface 512 of the main body.
The second region 514 is formed so that the second region A514a is larger than the second region B514b among the second region A514a facing the first region 513 and the second region B514b. The second region A514a has mounting holes 211b adjacent to each other in the direction sandwiching the first region 513. Therefore, it is possible to provide mounting intervals having different dimensions even in the direction of sandwiching the first region 513.

In the present embodiment, the rectangular main body surface 511 is provided with the substantially square first region 513, so that the second region A514a is provided with the adjacent mounting holes 211b in the direction of sandwiching the first region 513. It can be done, and the workability can be further improved.

In the present embodiment, the rectangular main body surface 511 has been described, but it may be an ellipse as long as it can be provided with adjacent mounting holes 211b in the direction sandwiching the first region 513. It may be in shape.

Further, in the first and second embodiments, the lighting device directly attached to the attached portion has been described, but the shape is not limited to the shape directly attached to the attached portion, and the shape is not limited as long as it is a lighting device. For example, an embedded lighting device embedded in an opening provided in the attached portion may be used.

In addition, some of the above embodiments 1 and 2 can be combined as appropriate. It is also possible to extract and combine a part of the above embodiments 1 and 2. Further, the present invention is not limited to the first and second embodiments, and can be appropriately changed.
