Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a lighting fixture and a system ceiling fixture.
[0002]
[Prior art]
Conventionally, a system ceiling fixture using a T-bar is disclosed in, for example, Japanese Patent Application Laid-Open No. 8-17238. Such a system ceiling fixture is designed to have a special size and performance, unlike a general implantable fixture, and the frame body is placed on the T-bar and the fixture body is fixed to the T-bar by a mounting bracket. ing. Further, the T-bar interval and the like vary among T-bar suppliers.
[0003]
In addition, fixing of a general implantable instrument is performed by, for example, inserting a suspension bolt fixed to the ceiling into a fixing hole formed in the instrument body and tightening with a nut. In addition, the external dimension of this kind of instrument is designed by partial optimization by external factors, such as an illumination design method and a user or a manufacturer.
[0004]
[Problems to be solved by the invention]
Therefore, the system ceiling apparatus is difficult to use as a general embedded apparatus, and the embedded apparatus is also difficult to use as a system ceiling apparatus. For this reason, it has the subject that the design and manufacturing cost regarding each instrument cannot be reduced easily.
[0005]
On the other hand, there are various problems with T-bar spacing, such as T-bar spacing, but a system ceiling that standardizes modules and saves labor in construction by unifying the T-bar spacing to 640 mm, especially in Europe and the United States. Some supply.
[0006]
It is an object of the present invention to provide a lighting fixture and a system ceiling fixture that can be commonly used for an implantable fixture and a system ceiling fixture and are suitable for a system ceiling having a T-bar interval of 640 mm.
[0007]
According to the first aspect of the present invention, there is provided a bottom portion having a first attachment portion provided so that it can be attached to a suspension bolt when it cannot be attached to the T bar, a side portion provided around the bottom portion, and a distance between the T bars. Is about 260 mm, the distance between the T-bar and the second mounting portion provided on the end side in the longitudinal direction from the first mounting portion that can mount the mounting bracket to be mounted on the T-bar. When the unit is installed on the system ceiling with a standard of about 640 mm and the interval between the T bars is 1280 mm, the mounting bracket to be mounted on the T bar is installed in the short side direction. An instrument main body configured to have a short side mounting portion and an opening opposed to the bottom portion; formed in a substantially quadrangular shape, and at least two outer dimensions in the longitudinal direction Is configured to be about 1260 mm to about 1270 mm, and is disposed to cover the periphery of the opening of the instrument body; a reflector disposed in the instrument body; A lighting apparatus comprising: a light source disposed opposite to the lighting apparatus; and a lighting device disposed in the apparatus main body for lighting the light source.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a first embodiment of the present invention will be described with reference to the drawings.
[0011]
FIG. 1A is a rear view of a lighting fixture for embedding according to a first embodiment of the present invention, FIG. 1B is a side view thereof, and FIG. 1C is a cross-sectional view of FIG.
[0012]
In the figure, the lighting fixture is arranged in opposition to the fixture body 1, the frame 2 provided in the fixture body 1, the reflector 3 provided in the appliance body 1, and the reflector 3. The light source 4 is provided and a lighting device 5 that is disposed in the instrument body 1 and lights the light source 4.
[0013]
The instrument body 1 has a bottom portion 1b having a first mounting portion 1a provided so as to be attached to a mounting portion such as a suspension bolt, a side portion 1d provided around the bottom portion 1b, and a mounting portion such as a T-bar. The second mounting portion 1c for mounting the mounting bracket to be mounted and the opening 1e facing the bottom portion 1b are provided.
[0014]
And the attachment hole which is the 1st attachment part 1a provided so that it could attach to to-be-attached parts, such as a suspension bolt, was opened at about 800 mm space | interval. Therefore, in this case, the second attachment portion 1a is not used.
[0015]
Further, the frame body 2 is formed in a substantially quadrangular outer shape, and is configured so that the outer dimension of at least two sides in the longitudinal direction is about 1260 mm to about 1270 mm, and covers the periphery of the opening 1 e of the instrument body 1. Arranged. The outer diameter of the two sides in the short direction is about 244 mm.
[0016]
Therefore, it can be disposed in a buried hole formed in the ceiling with a vertical dimension of about 1235 mm and a horizontal dimension of about 220 mm, and can be fixed with a suspension bolt and a nut.
[0017]
Hereinafter, a second embodiment of the present invention will be described with reference to the drawings.
[0018]
FIG. 2A is a rear view of a T-bar luminaire showing a second embodiment of the present invention, FIG. 2B is a side view thereof, and FIG. 2C is a cross-sectional view of FIG. This embodiment is different from the first embodiment in the following points.
[0019]
First, the outer diameter of the two sides in the short direction of the frame 2 is about 250 mm. This is the case when the T-bar interval is about 260 mm.
[0020]
Next, the T-bar fixing bracket 6 that is the mounting bracket 6 attached to the T-bar or the like is attached to the second attachment portion 1c. The lighting fixture is fixed to the T-bar. Therefore, in this case, the first attachment portion 1a is not used.
[0021]
The third embodiment of the present invention will be described below with reference to the drawings.
[0022]
FIG. 3 (a) is a rear view of a ceiling luminaire modularized with a T-bar interval of 640 mm, showing a third embodiment of the present invention, (b) is a side view, and (c) is (b). FIG.
[0023]
