[Background Art] Figure 5 shows this type of lighting equipment.
Angles 4 and 5 are formed downward from both sides of the top plate 3a of the lighting fixture body 3, respectively, and the angles 4 and 5 are caulked to the frame 6 at their lower parts. The lighting fixture main body 3 is inserted from below and embedded in an opening 2 formed in the ceiling material 1, and the frame 6 is located on the lower surface of the periphery of the opening 2. The lighting fixture body 3 is fixed to the ceiling material 1, which is a construction material, in the following manner. In other words, the mounting brackets 7 and 8 provided on the angles 4 and 5
moves up and down in the grooves 9 formed in the vertical direction of the angles 4 and 5, and the mounting brackets 7 and 8 are brought into contact with the upper surface of the ceiling material 1, and the frame 6 is brought into contact with the lower surface of the ceiling material 1, and the installation is completed. This is done by sandwiching the ceiling material 1 between the metal fittings 7 and 8 and the frame 6. The bowl-shaped reflecting plate 10 is held by a mounting spring (not shown) provided on the side of the top plate 3a. At the end of the lighting device body 3, power supply components such as a ballast, a glow bulb to be attached to a glow socket, a lamp socket 12 to which a lamp 11 is attached, and a terminal block 13 to which an external power line is connected are arranged. .

Here, as shown in FIG. 5 of the lighting fixture main body 3, the lamp 11 is placed horizontally in order to reduce the height H of the lighting fixture main body 3, and the lighting fixture main body 3 with the power supply parts attached is placed horizontally. The end side of is shown in Figure 5a.
As shown in , it protrudes beyond the diameter of the opening 2 of the ceiling material 1 (the shaded area in the figure). Therefore, since the diameter dimension A of the opening 2 is the mounting dimension, the end of the lighting fixture body 3 where the power supply component is attached has the mounting dimension A.
The problem is that when the lighting fixture body 3 is inserted through the opening 2 of the ceiling material 1, it is very difficult to install, and the ceiling material 1 and the lighting fixture body 3 are damaged during insertion. Also, when the diameter of the opening 2 is increased, it becomes larger than the diameter of the frame 6,
The lighting fixture main body 3 cannot be attached to the opening 2.

[Purpose of the invention] The present invention has been provided in view of the above points, and is intended to provide a lighting fixture that is easy to install without increasing the diameter of the opening. be.

This is a characteristic feature.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.
The gist of the present invention is that the power supply section 14 and the main body section 15 are pivotably attached, that is, swingable, and the other configurations are the same as the conventional ones, so a description of the same parts will be omitted. That is, as shown in FIG. 2, the lighting fixture main body 3 includes a main body part 15 having mounting fittings 7, 8, a frame 6, a reflector 10, etc., and a lamp socket 1.
2. The power supply section 14 is composed of a ballast, a terminal block 13, etc., and a mounting case 16 for mounting each part of the power supply section 14, and a mounting bracket 20 for mounting each part of the main body section 15. 14 and the main body portion 15 are provided with connecting means for freely connecting and fixing the body portion 15 in a pivotable manner. That is, locking pieces 17 are integrally formed upwardly on both sides of the end of the mounting case 16, and
A bolt 18 is provided vertically from the lower surface of the top plate 16a on the side closer to the power supply section 14 than the locking piece 17. This bolt 18
A nut 19 is screwed onto. On the other hand, the main body part 15
A bent piece 21 is bent upward at the outer end of the top plate 20a of the side mounting bracket 20.
A locking hole 22 into which the locking piece 17 is inserted and locked is bored between the top plate 20a and the top plate 20a. Furthermore, a notch 23 into which the bolt 18 is laterally inserted is formed at the end of the top plate 20a on the side of the power supply section 14 in a direction that widens toward the opening.
In addition, the dimension X between the notch 23 and the locking hole 22,
The dimension X' between the locking piece 17 and the bolt 18 is approximately the same.

Thus, the locking piece 17 is inserted and locked into the locking hole 22, the bolt 18 is inserted through the notch 23, and the nut 19 is screwed onto the bolt 18. When installing the lighting fixture main body 3 in the opening 2 of the ceiling material 1, it is performed as follows. That is, as shown in FIG. 3, by loosening the nut 19, the mounting case 16 can swing around the locking hole 22 of the mounting bracket 20 into which the locking piece 17 is inserted. Therefore, as shown in FIG. 1, the power feeding part 14 is tilted upward from the main body part 15 and inserted into the opening 2 of the ceiling material 1 from below first, and then the main body part 15 is inserted into the opening 2. . After inserting the lighting fixture body 3, return the power supply part 14 to its original position and screw the nut 19.
4 and the main body part 15 are connected and fixed. As shown in FIG. 3, a retaining portion 24 is formed at the lower end of the bolt 18 to prevent the nut 19 from falling out, the diameter of which is larger than that of the threaded portion. FIG. 4 shows a perspective view of the entire lighting fixture body 3. FIG. With this configuration, the height of the lighting fixture main body 3 is lowered and the power feeding part 14 is formed laterally than the main body part 15,
Even if the entire diameter of the ceiling material 1 becomes larger than the diameter of the opening 2, the lighting fixture main body 3 can be placed in the opening 2 without increasing the diameter of the opening 2.

[Effects of the invention] As mentioned above, the present invention is a recessed lighting fixture that is inserted from below the opening formed in the ceiling material and placed on the back side of the ceiling. A main body made of metal fittings, a reflector, etc., arranged corresponding to the opening, and a ballast, a lamp socket, which is formed integrally with the main body and protrudes laterally from the opening and is arranged above the ceiling material. , a power supply section having a terminal block for power supply, etc.
Since the power feeding part is provided with a connecting means for connecting and fixing the power feeding part in a pivotable manner using the main body side as a fulcrum, the power feeding part and the main body part can be pivotably connected by the connecting means and the power feeding part can be tilted from the main body part. , insert the power supply part into the opening first, then insert the main body part into the opening,
After that, by connecting and fixing the power supply part and the main body part using the connecting means, the height of the lighting fixture body is lowered and the power supply part is formed laterally than the main body part, so that the whole body is the diameter of the opening in the ceiling material. Even if the diameter of the lighting fixture is larger than that of the opening, the lighting fixture body can be placed in the opening without increasing the diameter of the opening. It has the advantage of being low in height and easy to install.Furthermore, a bolt is hung downward from the power supply part at a predetermined distance from the pivot fulcrum, and a nut is screwed onto the bolt. However, since we have provided a notch in the main body that allows the bolt to be inserted from the side, after inserting the main body into the opening of the ceiling material and installing it,
The power supply part can be fixed by rotating the power supply part to a predetermined position, inserting a bolt into a notch, and tightening a nut. Of course, even if the nut is screwed onto the bolt, the power feeding part can be rotated by loosening the nut, and when fixing the power feeding part, simply insert the bolt into the notch with the nut attached to the bolt, and tighten the nut. This makes it easy to fix the power supply part.
