[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting fixture, and more particularly to a ceiling-mounted lighting fixture for one lamp.

[0002]

2. Description of the Related Art Recently, as shown in FIG.
C channel 32 or M bar 3 previously placed on ceiling 31
In many cases, it can be attached to the ceiling suspension material 34 such as 3
The gap (behind the ceiling) between the ceiling material 30 and the ceiling 31 is becoming increasingly smaller. Moreover, in many cases, the air conditioning duct 35 and the like are already arranged on the C channel. For this reason, a ceiling-mounted lighting fixture attached to a mounting bolt 36 hanging down from the ceiling 31 has been used as a lighting fixture 37 having a small embedding depth as shown in FIG.

[0003]

However, in the case of a lighting fixture for two or more lamps, a mounting bolt hanging from the ceiling is mounted between the lamps, and a nut screwed to the mounting bolt is externally (downward). A lighting fixture with a small embedding depth could be constructed by covering it with a V-shaped reflector so that it could not be seen from the outside, but in the case of a lighting fixture for one lamp,
I can't do that.

In the case of a lighting fixture for one lamp, FIG. 12 and FIG.
3, the lamp 40 and the reflector 41 are housed,
A ballast 43 and the like are arranged in a box-shaped main body 42 having an open lower surface, and the main body 42 is attached to mounting bolts 44 hanging from the ceiling.
12 is fixed directly (FIG. 12) or via a U-shaped fixture 45 disposed on the upper surface of the main body 42 (FIG. 13). Projecting above the channel 32,
In some cases, the air conditioner was hit and the air conditioner had to be moved.

SUMMARY OF THE INVENTION An object of the present invention is to provide a ceiling-mounted luminaire for a single lamp having a small burying depth.

[0006]

According to a first aspect of the present invention, there is provided a single-lamp ceiling-mounted luminaire having a horizontally long reflector having a cross-sectional shape having a space portion obliquely upward and outward and left and right. A long main body that is disposed in one of the outer left, right, diagonally upper space portions of the reflector and extends along the longitudinal direction of the reflector, and is fixed so as to be perpendicular to the main body and extends along the outer periphery of the cross section of the reflector. And a plurality of holders that extend and hold the reflectors, accommodate electrical components such as stabilizers in the main body, and mount and fix mounting bolts hanging from the ceiling to the main body.

[0007] In the single-lamp ceiling-mounted lighting device according to the second aspect, an emboss projecting downward is provided in the vicinity of a bolt mounting hole provided in the main body.

[0008]

According to the first aspect of the present invention, in the one-lamp ceiling-mounted lighting device, the lighting device is suspended from a ceiling at a position deviated from the center line of the reflector.

[0009] In the ceiling-mounted lighting fixture for one lamp according to the second aspect, when a nut is screwed into the mounting bolt via a washer and tightened, the washer and the emboss come into contact, and the holder is leveled. To prevent a gap from being formed between the edge of the reflector and the ceiling material.

[0010]

1 and 2, a single-lamp ceiling light fixture 1 of the present invention includes a reflector 2, a main body 3, and a holder 4. 2a is a socket previously attached to the reflector. The reflector 2 has a horizontally long shape with an open lower surface, and has a space portion 5 in the cross-sectional shape, as shown by oblique lines on the outer side, diagonally above and right as shown in FIG. The outline 6 of the reflector 2 is not limited to a semicircle, but may be a straight line like a dotted line 6a.

The main body 3 is a long body having a U-shaped cross section, and is disposed in one of the left, right, diagonally upper space portions 5 outside the reflector 2, and extends along the longitudinal direction of the reflector 2. Body 3
Inside, a ballast 7 and a terminal block 8 are arranged.

The holder 4 is fixed to the vicinity of both ends of the main body 3 so as to be orthogonal to the main body 3. One side 4a extends along the semicircular outline of the reflector 2, and the other side 4b has a concave portion. 4c
Is provided, and then extends downward, and bent portions 9a and 9b which are in contact with the ceiling material are provided at the end portions on both sides thereof.

As shown in FIGS. 1 and 4, a bolt mounting hole 11 for engaging with a mounting bolt 10 is provided on the upper surface of the holder 4 and a corresponding portion of the main body 3. Bolt mounting hole 11
5 is flared so that the mounting bolts can be easily inserted as shown in FIG. A screw 12 for fixing the reflector 2 is provided on the inner side of the upper surface of the holder 4 in a downward direction. Further, an emboss 13 protruding downward is provided inside the upper surface near the tip of the bolt attachment hole 11 of the main body 3.

[0014] The ceiling-mounted lighting equipment 1 for one light of the present invention.
6 is first inserted into the mounting hole 15 with the concave portion 4c side first, and the mounting bolt 10 is inserted into the bolt mounting hole 11 as shown in FIG. that time,
Since the side 4a of the holder 4 is curved, the insertion can be performed smoothly. As shown in FIGS. 7 and 8, the washer 16 is fitted to the mounting bolt 10 and the nut 17 is screwed, and then the nut 17 is tightened.

In the initial stage of tightening, the bent portion 9a contacts the lower surface of the ceiling member 14, but the washer 16 is inclined due to the emboss 13 (FIG. 8). 9 and 10, the washer 16 becomes horizontal as shown in FIG. 9 and FIG. 10, so that the holder 4 also becomes horizontal, and the bent portion 9b comes into contact with the lower surface of the ceiling member 14, so that there is no gap.

After the main body 3 is fixed to the mounting bolts 10, the reflector 2 is fixed to the decorative screws 18 using the screws 12 of the holder 4.
(Fig. 1) and fix.

[0017]

According to the first aspect of the present invention, in the one-lamp ceiling-mounted luminaire, a main body is disposed in a space obliquely above the right, left, outside of the reflector, and electric parts such as a ballast are housed in the main body. And
In addition, since the mounting bolts hanging from the ceiling are fixed by the main body, the depth of the lighting fixture can be reduced, and there is no protrusion above the upper surface of the reflector, so that it hits the air conditioning equipment on the C channel There is nothing.

[0018] In the lighting fixture of the single-lamp ceiling type according to the second aspect, when a nut is screwed into the mounting bolt via a washer and tightened, the washer and the emboss come into contact with each other.
Since the holder and the reflector are horizontal, it is possible to prevent a gap from being formed between the edge of the reflector and the ceiling material.
