In this embodiment, the holding member 310 is attached to the mounting parts 114a and 114c. The holding member 310 may also be attached to the mounting parts 114b and 114d. By fixing the holding member 310 to the diagonally arranged mounting parts 114, it is possible to prevent the holding member 310 from interfering with the part of the pipe P that protrudes into the embedded box 100 when the pipe P is attached to the embedded box 100.

The fixing member 315 fixes the lighting device 200. The fixing member 315 has a case 320 and a socket 330.

The case 320 is attached to the retaining member 310 with two screws B3.

The socket 330 is attached to the case 320 by four screws B4. A pair of engagement holes 332 are formed in the socket 330. The socket 330 secures the lighting fixture 200. More specifically, the lighting fixture 200 is attached to the socket 330 by engaging the lighting fixture 200 with the engagement holes 332. The socket 330 electrically connects to the wiring inserted into the recessed box 100. The socket 330 has contacts. The contacts are electrically connected to the wiring. Therefore, when the lighting fixture 200 is attached to the socket 330, the terminals of the lighting fixture 200 are electrically connected to the contacts.

The mounting fixture 300 according to an embodiment of the present invention will be further described with reference to Figure 3. Figure 3 is a cross-sectional view of the recessed box 100, the lighting fixture 200, and the mounting fixture 300 taken along line III-III in Figure 2(a).

As shown in FIG. 3, the lighting fixture 200 is attached to the ceiling CL. In this embodiment, the ceiling CL is made of concrete C. The recessed box 100 and the pipe P are embedded in the ceiling CL. That is, the recessed box 100 and the pipe P are surrounded by the concrete C. The hanging bolt B fixes the recessed box 100.

The holding member 310 has a first surface 310a and a second surface 310b. The second surface 310b is opposite to the first surface 310a. The first surface 310a faces the -Z direction (downward). The second surface 310b faces the +Z direction (upward). The holding member 310 holds the fixing member 315 on the first surface 310a. In detail, the holding member 310 holds the case 320 on the first surface 310a. The second surface 310b faces the embedded box 100 at a predetermined distance. Therefore, the distance between the hanging bolt B and the holding member 310 can be increased. As a result, the lighting fixture 200 and the socket 330 can be prevented from interfering with the hanging bolt B. Furthermore, a space S is formed on the second surface 310b side (for example, the upper side). As a result, a space for providing the external wiring CB1 and the internal wiring CB2 can be secured. The external wiring CB1 is a wiring connected to an external power source (not shown). The internal wiring CB2 is a wiring connected to the socket 330. The external wiring CB1 and the internal wiring CB2 are connected via a connection part CN. The connection part CN is, for example, a connector. Furthermore, by setting the height of the holding member 310 to an appropriate dimension, the bottom surface of the lighting fixture 200 can be installed so as to be almost flush with the ceiling surface. Furthermore, by setting the height of the holding member 310 to an appropriate dimension, the position of the lighting fixture 200 can be set so as to make it easy to replace the lighting fixture 200.

The case 320 covers the side and back sides of the lighting fixture 200. The case 320 reflects the light emitted by the lighting fixture 200. Therefore, the light efficiency of the lighting fixture 200 can be improved.

Next, the installation method of the lighting fixture 200 will be described with reference to Figures 2(a), 2(b) and 3.

First, the holding member 310 is attached to the case 320. More specifically, the case 320 is attached to the holding member 310 using screws B2 and B3. It is preferable that the screw B2 is used to align the center positions of the holding member 310 and the case 320.

Next, attach the socket 330 to the case 320. More specifically, attach the socket 330 to the case 320 using screws B4.

Next, the holding member 310 and the cover part 120 are attached to the mounting part 114. More specifically, the holding member 310 and the cover part 120 are attached to the mounting parts 114a and 114c with screws B1. The cover part 120 is also attached to the mounting parts 114b and 114d with screws B1. Therefore, the case 320 and the socket 330 are attached to the recessed box 100 via the holding member 310.

Next, the embedded box 100 is attached to the hanging bolt B. More specifically, the hanging bolt B is passed through the through hole 1112 of the embedded box 100. Then, the nut N is screwed onto the tip of the hanging bolt B that has passed through the through hole 1112, thereby fixing the embedded box 100 to the hanging bolt B.

Next, the external wiring CB1 and the internal wiring CB2 are connected at the connection point CN. Therefore, the external power supplied from the external power source is supplied to the socket 330.

Next, concrete is filled around the embedded box 100, and the concrete is solidified around the embedded box 100. At this time, the concrete is filled up to the vicinity of the edge of the opening 121 of the cover part 120, and covers most of the cover part 120 except for the opening 121. As a result, the embedded box 100 is fixed to the back of the ceiling CL and cannot be removed.

Next, the lighting fixture 200 is attached to the socket 330. This completes the installation of the lighting fixture 200.

In this way, the lighting fixture 200 is attached to the back of the concrete ceiling CL via the holding member 310. Therefore, the lighting fixture 200 can be easily attached to the concrete ceiling CL without driving screws into the concrete.

Referring to Figures 4(a) and 4(b), the holding member 310 according to an embodiment of the present invention will be further described. Figure 4(a) is a top view of the holding member 310. Figure 4(b) is a cross-sectional view of the holding member 310 taken along line IVB-IVB in Figure 4(a).

As shown in Figures 4(a) and 4(b), the holding member 310 has a first plate-shaped portion 311, a second plate-shaped portion 312, and a connecting portion 313.

The second plate-shaped portion 312 is, for example, plate-shaped. The second plate-shaped portion 312 is, for example, flat. A through hole 3122 is formed in the second plate-shaped portion 312.

The connecting portion 313 connects the first plate portion 311 and the second plate portion 312. The connecting portion 313 has a third plate portion 313a, a first connection portion 313b, and a second connection portion 313c.

The third plate-shaped portion 313a is, for example, plate-shaped. The third plate-shaped portion 313a is, for example, flat. A through hole 3132 and a pair of through holes 3134 are formed in the third plate-shaped portion 313a. The through hole 3132 is formed in approximately the center of the third plate-shaped portion 313a. The pair of through holes 3134 are formed to face each other at equal intervals from the through hole 3132. The through hole 3132 is a hole for fixing the screw B2 (FIGS. 2 and 3). The pair of through holes 3134 is a hole for fixing the screw B3 (FIGS. 2 and 3).

The first connection portion 313b is, for example, plate-shaped. The first connection portion 313b connects the third plate-shaped portion 313a and the first plate-shaped portion 311.

The second connection portion 313c is, for example, plate-shaped. The second connection portion 313c connects the third plate-shaped portion 313a and the second plate-shaped portion 312.

The holding member 310 holds the fixing member 315 at the connecting portion 313. More specifically, the holding member 310 holds the case 320 at the connecting portion 313. The holding member 310 is also attached to the recessed box 100 at the first plate portion 311 and the second plate portion 312.

The third plate-shaped portion 313a is located farther from the opening 121 than the first plate-shaped portion 311 and the second plate-shaped portion 312 (Figure 3).

The case 320 according to the embodiment of the present invention will be further described with reference to Figures 5(a) and 5(b). Figure 5(a) is a top view of the case 320. Figure 5(b) is a cross-sectional view of the case 320 taken along line VB-VB in Figure 5(a).

As shown in Fig. 5(a) and Fig. 5(b), the case 320 has a first upper surface portion 321, a connection portion 322, a second upper surface portion 323, and a side surface portion 324. The case 320 is made of metal. The case 320 has a generally cylindrical shape that is open at the bottom. It is preferable that the inner surface of the case 320 is subjected to a reflective treatment such as white paint, silver paint, or glossy metal plating in order to efficiently reflect the light emitted by the lighting device 200. The case 320 may be made of resin.

The first upper surface portion 321 is, for example, disk-shaped. The first upper surface portion 321 is, for example, flat. The first upper surface portion 321 has a through hole 3212 and four through holes (through holes 3214a, 3214b, 3214c, and 3214d). The through hole 3212 is formed in approximately the center of the first upper surface portion 321. The through holes 3214a to 3214d are formed at equal intervals from the through hole 3212. The through hole 3212 is a hole for fixing the screw B2 (FIGS. 2 and 3). The through holes 3214a to 3214d are holes for fixing the screw B3 (FIGS. 2 and 3).

The second upper surface portion 323 is, for example, annular. The second upper surface portion 323 is, for example, flat. Through hole 3232, through hole 3234a, through hole 3234b, through hole 3234c, and through hole 3234d are formed in the second upper surface portion 323. Through hole 3232 is a hole for passing internal wiring CB2 (FIG. 3). Through hole 3234a, through hole 3234b, through hole 3234c, and through hole 3234d are holes for fixing screws B4 (FIG. 2).

The connection portion 322 connects the first top surface portion 321 and the second top surface portion 323. The side surface portion 324 connects to the second top surface portion 323.

As described above with reference to Figures 1 to 5, the mounting fixture 300 includes the fixing member 315 (case 320 and socket 330) and the holding member 310. The fixing member 315 fixes the mounting object (lighting fixture 200). The holding member 310 holds the fixing member 315. The holding member 310 is attached to the recessed box 100. Therefore, the mounting object is attached to the recessed box 100 via the holding member 310 and the fixing member 315. As a result, the mounting object can be easily installed. For example, when mounting the lighting fixture 200 to a concrete ceiling CL, the lighting fixture 200 can be easily mounted to the concrete ceiling CL without driving screws into the concrete.

In addition, by mounting the lighting fixture 200 to the recessed box 100, it is possible to prevent the lighting fixture 200 from protruding from the ceiling.

The holding member 310 holds the fixing member 315 on the first surface 310a. The second surface 310b faces the recessed box 100 at a predetermined distance. Therefore, the distance between the holding member 310 and the hanging bolt B can be increased. As a result, the lighting fixture 200 and the socket 330 can be prevented from interfering with the hanging bolt B. Furthermore, a space S is formed on the second surface 310b side (e.g., the upper side). As a result, a space for providing the wiring CB can be secured. Also, by setting the height of the holding member 310 to an appropriate dimension, the lower surface of the lighting fixture 200 and the ceiling surface can be installed so as to be almost flush with each other. Also, by setting the height of the holding member 310 to an appropriate dimension, the position of the lighting fixture 200 can be set so that the lighting fixture 200 can be easily replaced.

The fixing member 315 covers the side and rear sides of the lighting fixture 200. The fixing member 315 reflects light from the lighting fixture 200. Therefore, the light efficiency of the lighting fixture 200 can be improved.

It is preferable that the case 320 has a flange portion 325.

With reference to Figures 6, 7(a) and 7(b), a mounting fixture 300 according to an embodiment of the present invention will be described. Figure 6 is a cross-sectional view of the recessed box 100, the lighting fixture 200 and the mounting fixture 300. Figure 7(a) is a top view of the case 320. Figure 7(b) is a cross-sectional view of the case 320 taken along line VIIB-VIIB in Figure 7(a).

The mounting device 300 according to the embodiment of the present invention has a similar configuration to the mounting device 300 described with reference to Figures 1 to 5, except that the case 320 has a flange portion 325, so a description of the overlapping parts will be omitted.

6, 7(a) and 7(b), the case 320 has a flange 325. The flange 325 protrudes outward from the end of the case 320 (fixing member 315). The edge of the opening 121 of the cover part 120 overlaps with the flange 325. Therefore, the flange 325 can cover and hide the edge of the opening 121. As a result, even if the edge of the opening 121 has an uneven shape, the uneven part can be hidden, and the deterioration of the aesthetic appearance can be suppressed. For example, a rib (protrusion) for attaching the fixture may be formed at the opening 121 of the cover part 120. If the rib is not necessary, the worker cuts the rib when installing the lighting fixture 200. The part where the rib is cut is sharper than the part where the rib is not provided, and the aesthetic appearance may be deteriorated. However, the flange 325 can cover and hide the part where the rib is cut.

The cover portion 120 of the recessed box 100 is made of metal. Therefore, the dimensions of the opening 121 of the cover portion 120 are formed with relatively high precision. As a result, the dimensions of the protruding portion of the flange portion 325 can be made relatively small.

The mounting fixture 300 can also be used for ceiling hanging lights.

With reference to Figure 8, a mounting fixture 300 according to an embodiment of the present invention will be described. Figure 8 is a cross-sectional view of the recessed box 100, the mounting fixture 300, and the lighting fixture 400. Descriptions of overlapping parts with the mounting fixture 300 described with reference to Figures 1 to 5 will be omitted.

As shown in FIG. 8, the lighting fixture 400 is a ceiling lamp. The lighting fixture 400 includes an adapter 420, a power cord 430, a shade 440, and a light source 450.

In this embodiment, the object to be attached is the lighting fixture attachment 410. That is, the attachment 300 attaches the lighting fixture attachment 410 to the recessed box 100. The lighting fixture attachment 410 is a member for attaching the lighting fixture 400. The lighting fixture attachment 410 is, for example, a hook rosette or a hook ceiling.

The adapter 420 is attached to the lighting fixture fixture 410. By attaching the adapter 420 to the lighting fixture fixture 410, power supplied from the external wiring CB1 and the internal wiring CB2 is supplied to the light source 450 via the power cord 430. The light source 450 emits light.

The mounting fixture 300 can also be used for ceiling lights (direct ceiling mounted lights).

With reference to Figure 9, a mounting fixture 300 according to an embodiment of the present invention will be described. Figure 9 is a cross-sectional view of the recessed box 100, the mounting fixture 300, and the lighting fixture 500. Descriptions of overlapping parts with the mounting fixture 300 described with reference to Figures 1 to 5 will be omitted.

As shown in FIG. 9, the lighting fixture 500 is a ceiling light.

The lighting device 500 includes a power supply unit 510, a light source 520, and a shade 530. The power supply unit 510 supplies power to the light source 520. The light source 520 emits light.

In this embodiment, the object to be attached is the power supply unit 510. That is, the mounting fixture 300 attaches the power supply unit 510 to the recessed box 100. Therefore, the power supply unit 510 can be placed behind the ceiling CL. As a result, the portion protruding from the ceiling CL can be made thinner.

The above describes the embodiments of the present invention with reference to the drawings (Figs. 1 to 9). However, the present invention is not limited to the above embodiments, and can be implemented in various forms without departing from the gist of the present invention (for example, (1) to (2) shown below).
