Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to an improvement of a ceiling-embedded lighting fixture.

<Conventional technology and its problems> In this type of ceiling-embedded lighting equipment, if the ballast is installed and fixed at the upper end of the equipment body, the overall height becomes bulky, so it is difficult to install the ballast in the upper end of the equipment body. In such cases, the ballast immediately collides with the ceiling slab, etc., making it impossible to install it. Furthermore, since the ballast is quite heavy relative to the main body of the device, it can easily become unstable in the event of an earthquake or the like.

As a countermeasure for such problems,
-152218 and 56-14402 have been proposed.

However, according to the former configuration, the cylindrical mounting base frame 2 is formed to protrude significantly taller than the size of the lamp 27 and the reflector 24, so it is difficult to install it in a shallow attic space without restrictions. There is a stabilizer 4 at the corner position of the upper surface 2a,
Since it is only rotatably supported by the hinge 3, in order to embed the lighting fixture 1 into the ceiling board 8, it is difficult to tilt the mounting frame 2 even slightly.
Furthermore, if the stabilizer 4 is subjected to a shock, or if it encounters an earthquake even after it has been installed, the stabilizer 4 will immediately and easily fall down from the upper position P1 of the mounting base frame 2 to the side position P2. It is also less stable.

On the other hand, according to the latter first embodiment shown in FIG.
Since it is fastened to the instrument body 12 via the wing nut 19, it can be said that the installation stability can be maintained.
Coupled with the fact that the ballasts 14 are installed on the inclined side walls 10, the overall weight balance cannot be maintained unless the left and right pairs of the ballasts 14 are installed in parallel.
Not only does one of the so-called useless ballasts 14 have to be installed, but the overall weight increases considerably.

Also, in the second and third embodiments shown in FIGS. 3 to 5 of the latter, one stabilizer 15 is sufficient, but the stabilizer 15 is connected to the instrument via a rigid arm 16 of a certain length. Since the main body 12 is only rotatably supported on the frame 11a and the mounting side wall 11, when the main body 12 is embedded in the ceiling 12, it is prone to tilting, impact, and even earthquakes. If this occurs, the stabilizer 15 will easily become unstable, resulting in poor installation stability.

In any case, in the configuration of the above-mentioned known device, even if the ballast is electrically connected to the device body by a flexible wiring cord, it is difficult to completely remove and separate it from the device body. Because of the free direction and posture,
It is impossible to install it stably and firmly on a ceiling slab or other ceiling aggregates, and it must be said that there are still restrictions, as the lamp is installed vertically in the fixture body.

<Means for Solving the Problems> The present invention is intended to improve these problems, and for this purpose, it has a main body frame that is fitted into the ceiling board, and a box-type installation that is separate and independent from the main body frame. The frame base is equipped with a stabilizer built in and fixed in advance, and an almost inverted L-shaped top plate is fixed and integrated with the upper end of the main body frame, and the horizontal plate surface of the top plate is equipped with a stabilizer that is fixed from below. An almost conical reflector is installed in the lowered state, and sockets and terminals are attached to the vertical plate surface of the top plate, which hangs down from the end of the horizontal plate surface toward the outer peripheral surface of the reflector plate, as it is backed from the inside. The base is fixedly installed, and the lamp that extends from its socket in a horizontal position is introduced into the interior of the reflector plate, while the ballast installation frame is placed from above on the horizontal plate surface of the top plate, and the lamp is inserted into the horizontal plate surface of the top plate from above. a support that is removably installed with a plurality of screws, and is rotatably fitted to the installation frame of the ballast and the vertical plate surface of the top plate; By electrically connecting both ends of the flexible wiring cord to the ballast and terminal block through the The present invention is characterized in that it can be installed and fixed to a ceiling slab or other ceiling aggregate using a fixture that is inserted interchangeably into the extraction hole.

By being removably locked and fixed, it is in an installed state where it is suspended from the horizontal plate surface 15 of the top plate 14 on the vertical center line Y-Y of the main body frame 10.

Reference numeral 22 indicates a lamp outlet provided in a part of the body surface of the reflector plate 20, and reference numeral 23 indicates a lamp outlet provided on the vertical plate surface 16 of the top plate 14 from the inside so as to correspond to the outlet 22. a fixed socket into which the lamp 24 is aligned with the vertical centerline Y-Y.
It is mounted in a sideways horizontal position substantially orthogonal to the The lamp 24 passes through the escape port 22 and is introduced into the interior of the reflector plate 20.
Therefore, for example, by adopting a large product such as a so-called twin light as shown in the figure as the lamp 24, the overall height of the main body frame 10 can be made as low as possible and stable while reducing the illumination intensity. This means that it can be maintained. 25 is also a glow socket fixed to the vertical plate surface 16 of the main body frame 10;
Reference numeral 6 designates a terminal block which is also backed and fixed to the main body frame 10, and a wiring port 27 from this terminal block is formed as an opening in the vertical plate surface 16. Incidentally, a glow starter 28 is attached to the glow socket 25.

Further, 29 is a box-type installation frame that surrounds the stabilizer 30, and while being located on the vertical center line Y-Y of the main body frame 10, it is detachably installed and fixed to the top plate 14 from above. ing.

is introduced into the interior of the reflecting plate 20, while the installation frame 29 of the stabilizer 30 is placed from above on the horizontal plate surface 15 of the top plate 14, and positioned on the vertical center line Y-Y of the main body frame 10. A support 34 is attached to the installation frame 29 of the stabilizer 30 and the vertical plate surface 16 of the top plate 14 so as to be rotatable. , 35, by electrically connecting both ends of the flexible wiring cord 33 to the ballast 30 and the terminal block 26, the installation frame 29 of the ballast 30 is connected to the top plate 14 of the main body frame 10. Remove and separate it from the screw 31.
A fixture 31a that is inserted interchangeably into the extraction hole S of
Since it is specified that it can be installed and fixed to a ceiling slab or other ceiling aggregate F, it has the effect of reliably improving the problems of the prior art mentioned at the beginning.

That is, the present invention is not limited to simply changing the mounting position of the ballast 30 into two specifications, one at the top of the main body frame 10 and the other. It is built in and fixed to a box-type installation frame 29 that is separate and independent from the main body frame 10, and the installation frame 29 is detachably attached to the horizontal plate surface 15 of the top plate 14 in the main body frame 10 by means of a plurality of screws 31. Moreover, it is installed in a relationship located on the vertical center line Y-Y of the main body frame 10.

At that time, the flexible wiring cord 33 that electrically connects the ballast 30 and the terminal block 26 is connected at both ends to the installation frame 29 of the ballast 30 and the vertical plate surface 16 of the top plate 14. It is supported by supports 34 and 35 that are rotatably fitted.

Therefore, by removing the screws 31, the ballast 30 together with its installation frame 29 can be completely removed and separated from the top plate 14 of the main body frame 10, and the installation frame 29, which opens after removal, can be removed. By inserting another fixture 31a interchangeably from the hole S into the ceiling slab or other ceiling aggregate F, the stabilizer 30 can be installed and fixed to the ceiling aggregate F together with its installation frame 29. This allows construction work to be carried out in shallow attic areas without restrictions, and provides a stable and firm installation at all times, unaffected by earthquakes.

Moreover, when installing the installation frame 29 of the ballast 30 that has been removed and separated, even if its direction and posture are freely changed, the wiring cord 33 does not rotate at both ends. Support tool 3
