DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a lightweight, low-installation type lighting fixture mounted on a ceiling.

[0002]

2. Description of the Related Art A conventional recessed fluorescent lamp apparatus is composed of an apparatus body, a reflector, a lamp, a socket, a ballast and other wiring parts. The mass of a standard 40W2 fluorescent lamp apparatus is as follows. Although it depends on the type of the ballast, it is about 5 kg to 8 kg. Generally, when this type of equipment is mounted on a ceiling of an office or the like, the equipment is mounted by a special hanging bolt (anchor bolt) cast on a concrete floor (slab) on the upper floor during construction work. FIG. 10 shows a schematic side view of a conventional recessed lighting device, and a rectangular lighting device main body 1.
And a reflector 2 supported inside the instrument body. Sockets are arranged at both ends of the instrument body, and a straight tube fluorescent lamp is mounted between the sockets. The underside of the ceiling is configured such that a plurality of anchor bolts 3 serving as ceiling support brackets support a so-called C channel 4, a C channel 4 supports an M bar 5, and a M bar 5 supports a ceiling material 6. . A lighting fixture is attached to the opening of the ceiling material, and is held in the ceiling by hanging bolts 7 (stud bolts) connected to the fixture body. On the other hand, a lighting fixture such as a recessed downlight having a relatively light mass has a mass of about 2 kg and a mounting hole size of the ceiling material of φ100.
It is as small as about 200 mm. For this reason, it is possible to directly mount and support the ceiling material with a dedicated mounting bracket mounted on the fixture. However, common embedded fluorescent lighting fixtures
If you try to hold the lighting fixture directly on the ceiling without using the stud bolt, the ceiling will not be able to withstand the weight of the fixture and will be unable to support it and will be broken. I do.

Here, a general installation procedure for mounting a lighting fixture on a conventional ceiling will be described with reference to FIG. (1) Determining the arrangement of lighting equipment. (2) A special insert fitting is embedded in concrete during concrete placing work on an upper floor (slab). (3) Attach hanging bolts (anchor bolts and stud bolts) to the insert after completion of the upper floor construction. (4) Fix the C channel and the M bar to the anchor bolt. (5) Attach ceiling material to M bar. (6) Provide mounting holes (openings) for lighting fixtures in the ceiling material. (7) Adjust the positions of the stud bolt and the opening. (8) Change the position of the stud bolt or strike the insert bracket again. (9) C-channel or M-bar is cut as required. (10) Pull the power supply line into the instrument body, tighten the instrument body to the stud bolt with a nut, and attach it to the ceiling opening. (11) Connect the power supply and attach the reflector to the instrument body. (12) Set the lamp and complete the installation.

[0004]

However, according to the construction method, there are the following problems. The placement of lighting fixtures on the ceiling is more efficient after the layout of the room has been determined after the concrete casting work, but in practice, a special insert metal fitting is used when placing concrete on the upper floor. The mounting position of the lighting fixture will be determined when embedded in the interior. Actually, there are many changes in the positions of the lighting fixtures before and after the concrete is placed on the floor, so that there is a problem that the work of embedding the insert fittings in the concrete and the work of attaching the suspension bolts need to be performed again. Also, in the case of a fluorescent lamp fixture using a general fluorescent lamp (diameter 32 mm), the height of the ceiling mounting becomes 100 mm or more, and it is necessary to cut the C channel and the M bar, which are ceiling support brackets, at the time of installation. In addition, there is a problem that the reinforcement work after cutting the C channel is troublesome work, the work is complicated, and an excessive work time is required. Recently, the pipe diameter is 2
A C-channel avoidance type lighting fixture using a 5.5 mm high-frequency fluorescent lamp (T8 lamp) dedicated to high-frequency lighting and having a ceiling embedded height as small as 26 mm has begun to spread. If it is necessary to adjust the positional relationship with the M bar in the ceiling,
There is a problem that the cutting operation is required.
