Embodiment 2. FIG.
As described above, when the instrument main body 300 is embedded in the ceiling 901, the height of the instrument main body 300 needs to be set as low as possible because there are many restrictions in the ceiling. In addition, when the lighting device 200 is built in the fixture main body 300, the height of the fixture main body 300 increases. Therefore, in the first embodiment, the lighting device 200 is arranged outside the fixture main body 300.
However, if the lighting device 200 is attached to an arbitrary position of the fixture main body 300, the lighting device 200 and the fixture main body 300 may not be installed on the ceiling 901 without entering the size of the hole formed in the ceiling 901.
Therefore, the display device 100 described in each embodiment is characterized in that the end portion of the lighting device 200 is attached to the fixture body 300. That is, the lighting device 200 is displaced to a position that does not hinder the attachment to the bolt 903 and is fixed to the outer surface of the top surface of the instrument main body 300, and a part of the box-shaped housing is protruded from the top surface.

20, 21, and 22, each item has the following dimensions.
The item “A” indicates “the hole diameter of the ceiling 901”.
The item “B” indicates “the diameter of the instrument main body 300”.
The item “C” indicates “height between the appliance main body 300 and the lighting device 200”.
The item “D” indicates “the distance from the center of the appliance main body 300 to the outer end of the lighting device 200 externally attached to the appliance main body 300”.
The item “E” indicates “the thickness of the ceiling 901”.
The item “F” indicates “the width of the lighting device 200”.
The item “G” indicates “the height of the bolt 903 at the portion to be inserted into the instrument main body 300”.
The item “H” indicates “the height of the instrument main body 300”.
The item “I” indicates “the height of the lighting device 200”.

  The relationship between the position / dimensions of the lighting device 200, the instrument main body 300, and the bolt 903 will be described with reference to FIGS.

The ceiling 901, the lighting device 200, and the appliance main body 300 have the following restrictions.
(1) The height “J” inside the ceiling 901 (see FIG. 17)
In a general construction such as mounting a downlight, the height “J” inside the ceiling 901 is 80 to 100 millimeters.
(2) Hole diameter “A” in the ceiling 901 (see FIGS. 17 and 18)
In the case of general construction such as attaching a downlight, the diameter of the hole formed in the ceiling 901 is about 100 to 200 mm. In particular, holes with a diameter of 125 millimeters, 150 millimeters or 175 millimeters are applied as standard sizes.
(3) Size of lighting device 200 (height “I” [see FIGS. 17 and 18)]
Since the lighting device 200 incorporates an “AC-DC converter” that converts commercial current into DC current, a “voltage converter” that steps down the commercial voltage, and a charger that charges the battery 820, the lighting device 200 requires a certain size or more. For example, the height “I” of the lighting device 200 is desirably 20 millimeters or more.
(4) Size of instrument body 300 (diameter “B”, height “H” [see FIGS. 17 and 18])
Since the instrument main body 300 is inscribed in the hole of the ceiling 901 and installed inside the ceiling 901, the diameter “B” of the instrument main body 300 depends on the hole diameter “A” of the ceiling 901. For example, the diameter “B” of the instrument main body 300 is set to a size 5 mm smaller than the hole diameter “A” of the ceiling 901. The diameter “P” of the collar 330 is larger than the hole diameter “A” of the ceiling 901. In addition, as will be described below, the instrument body 300 includes components such as a power terminal block 810, a battery 820, and an inspection switch unit 830, and at least a certain amount in order to secure wiring and work space for connecting the components. Requires height. For example, the height “H” of the instrument body 300 is desirably 50 millimeters or more. There is a relationship of “I + H <J”.

Furthermore, the lighting device 200, the appliance main body 300, the ceiling 901, and the bolt 903 have the following restrictions as relative relationships.
(5) Height “G” of the bolt 903 at the portion to be inserted into the instrument body 300 (see FIG. 18)
When the instrument body 300 is fixed to the bolt 903 with the nut 904, the height “G” (the portion inserted into the instrument body 300) of the bolt 903 for attaching the nut 904 is 15 to 15 in order to obtain sufficient fixing strength. It is desirable to provide about 25 millimeters. There is a relationship of “G <H”.
(6) Width “F” of the lighting device 200 (see FIG. 19)
In order to obtain a sufficient fixing strength between the lighting device 200 and the appliance main body 300, it is desirable that the width “F” of the lighting device 200 is 60 mm or more so as to contact the fixture main body 300. Further, since the bolt 903 is inserted in the center of the appliance main body 300, the width “F” of the lighting device 200 is less than the diameter of the appliance main body 300. There is a relationship of “F <B <A”.
(7) The height “M” of the lighting device 200 from the ceiling 901 when the lighting device 200 externally attached to the fixture body 300 is inserted obliquely from the hole of the ceiling 901 (see FIG. 17).
The height “M” needs to be equal to or less than the height “J” inside the ceiling 901. For this reason, the length “O” (see FIG. 18) of the lighting device 200 of the portion that has gone out of the fixture body 300, the angle at which the lighting device 200 is inserted into the hole in the ceiling 901, and the height “I” of the lighting device 200 are: Depending on the height “J” inside the ceiling 901, it is necessary to satisfy the relationship “M ≦ J” as a result.
(8) Distance from the end of the hole in the ceiling 901 to the end from the hole center of the ceiling 901 of the lighting device 200 when the lighting device 200 externally attached to the fixture body 300 is inserted obliquely from the hole in the ceiling 901 “L” (see FIG. 17)
The distance “L” needs to be equal to or less than the distance “K” from the end of the hole in the ceiling 901 to the end of the bolt 903. For this reason, the length “N” of the lighting device 200 in the portion in contact with the fixture body 300, the angle at which the lighting device 200 is inserted into the hole in the ceiling 901, and the height “I” of the lighting device 200 are the end of the hole in the ceiling 901. Depends on the distance “K” from the end to the end of the bolt 903, and as a result, the relationship “L ≦ K” needs to be satisfied.

In each embodiment, there is a general relationship between items as follows.
(A) N≈ (B-bolt insertion hole diameter) / 2
(B) D: B≈1: 1
(C) H: I≈2: 1
(D) G: H≈1: 4
(E) F: B≈1: 1

As described above, the lighting device 200 can be attached to the outside of the appliance main body 300 and installed on the ceiling 901, so that the height of the appliance main body 300 in the ceiling 901 can be reduced. In addition, since the heat generated from the lighting device 200 itself can be dissipated to the outside of the fixture main body 300, each component attached to the fixture main body 300 can be protected from the heat generated from the lighting device 200.
Further, since the lighting device 200 with the fixture body 300 attached to the outside can be installed on the ceiling 901, the display device 100 described in each embodiment has a special hole in the ceiling 901 for installing the display device 100. Even if it is not installed on the ceiling, it can be installed on the ceiling 901 using a ceiling hole of a standard size opened for the purpose of installing a downlight or the like.

Further, in the second embodiment, the box-shaped housing of the lighting device 200 is arranged so that the box-shaped housing of the lighting device 200 does not hit the bolt 903 above the hole of the ceiling 901 after the above-described lighting device fixing step. The portion of the lighting device 200 that protrudes from the top surface is directed obliquely upward, and the box-shaped housing of the lighting device 200 is ceiling-mounted from the portion of the box-shaped housing of the lighting device 200 that protrudes from the top surface. The housing insertion process for inserting into the hole 901 has been described.
In addition, after the housing insertion step, the fixing step of fixing the fixture 400 to the bolt 903 by inserting the bolt 903 into the bolt insertion hole 317 while fitting the instrument body 300 into the hole of the ceiling 901 has been described.
