Description

  The present invention relates to a lighting apparatus applied to a downlight or the like that is installed by being embedded in an embedding hole of a ceiling material.

2. Description of the Related Art Conventionally, there has been known a lighting fixture including a fixture main body having a main body formed with a bolt through hole through which a ceiling suspension bolt is passed, and a lighting device that lights a light source attached to and supported by the fixture main body. (For example, refer to Patent Document 1).
Patent Document 1 discloses a pair of base members that have a ceiling locking end portion that is hooked from below on the edge portion of the embedded hole and that is passed through the embedded hole, and is connected to the base member so as to be vertically rotatable. And a body support member that supports the instrument body.
And patent document 1 arrange | positions the several installation apparatus which supports an instrument main body to a relatively low position and a high position by rotating a main body support part, and arrange | positions a light source inside and the downward direction of an instrument main body. And a light control device having a cover portion that covers the ceiling locking end portion.

JP 2009-146818 A (FIG. 1, claim 1)

Patent Document 1 can form a light shielding angle according to the selection of a light control device having a different height, and can be embedded in the ceiling without requiring a dedicated installation device regardless of the selection.
By the way, as shown in FIG. 10, similarly to Patent Document 1, the lamp body 103 that houses the light source 101 and to which the reflector 102 is attached is attached to the frame 105 that is fixed to the ceiling suspension bolt 104. Has been proposed.

However, in such a conventional lighting fixture 100, since the lamp body 103 protrudes facing the ceiling suspension bolt 104, the bolt suspension fitting 104 included in the frame 105 is inserted into the ceiling suspension bolt 104, and then the nut. The space for tightening etc. is small.
Therefore, in such a conventional lighting fixture 100, in order to secure a tightening space for the ceiling suspension bolt 104, the height dimension of the bolt suspension fitting 106 of the frame 105 must be increased.
Therefore, such a conventional lighting fixture 100 cannot secure a tightening space for the ceiling suspension bolt 104 and cannot be reduced in size because the overall height dimension becomes large.

In addition, since such a conventional lighting fixture 100 has a small space between the lamp body 103 and the bolt suspension fitting 106 of the frame body 105, the power line 107 drawn from the lamp body 103 and connected to an external circuit is connected to the lamp. It may be sandwiched between the main body 103 and the bolt suspension fitting 106.
Therefore, such a conventional lighting apparatus 100 may break the power supply line 107 when the power supply line 107 is sandwiched.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a lighting apparatus that can be reduced in size and can prevent a power line from being caught.

  The luminaire according to the present invention includes an attachment member attached to a ceiling suspension member on the ceiling side, a lamp body supported by the attachment member, a power line housed in the lamp body and drawn from the ceiling surface. An LED light-emitting unit that is electrically connected to the lamp body, and the lamp body has a recess that houses the ceiling suspension member.

  In the lighting fixture according to the present invention, the mounting member has a bolt suspension fitting fixed to the ceiling suspension member, and has a gap through which the power line is inserted between the bolt suspension fitting and the lamp body. .

  According to the lighting fixture concerning this invention, it can be reduced in size and there exists an effect that the pinching of a power wire can be prevented.

Can be downsized.

(Second Embodiment)
Next, the lighting fixture of 2nd Embodiment which concerns on this invention is demonstrated.
In the following embodiments, components that are the same as those in the first embodiment described above or components that are functionally similar are denoted by the same or corresponding reference numerals in the drawings, and the description thereof is simplified or omitted. To do.

As shown in FIG. 5, the lighting fixture 50 according to the second embodiment of the present invention is fixed to a pair of ceiling suspension bolts 51 and 52 that are attached above the ceiling member 90.
In the lamp body 53, a pair of bolt housing recesses 54 and 55 are independently formed in the central side portion of the radiating fin 18. These bolt housing recesses 54 and 55 are formed in a bottomed hole that forms an oval space in plan view.

As shown in FIG. 6, the bolt suspension fitting 56 has a pair of bolt holes 57 and 58 through which the ceiling suspension bolts 51 and 52 are inserted.
The bolt housing recesses 54 and 55 are sufficiently longer than the length L5 from the top of the lamp body 53 at the lower end of the ceiling suspension bolts 51 and 52 attached to the bolt suspension fitting 56 of the frame 13 by the nuts 26 and 26. Has a large depth dimension L6.
The bolt receiving recesses 54 and 55 have an inner diameter L8 that is sufficiently larger than the outer diameter L7 of the nuts 26 and 26 screwed into the ceiling suspension bolts 51 and 52 on the lower surface of the bolt suspension metal fitting 56 of the frame 13. Have.

In the lighting fixture 50, the bolt holes 57 and 58 of the bolt suspension 56 of the frame 13 are inserted into the ceiling suspension bolts 51 and 52, respectively, and the nuts 26 and 26 are attached to the ceiling suspension bolts 51 and 52 on the lower surface of the bolt suspension bracket 56.
