Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a lighting fixture such as a downlight that is embedded in an opening formed in a ceiling material.

[Background Art] Figure 4 shows this type of lighting equipment.
A horizontal plate 3b is integrally provided from the rear part 3a of the lighting fixture body 3. Angles 4 and 5 are formed downward from both sides of the horizontal plate 3b, and the angles 4 and 5 are caulked to the frame 6 at their lower portions. 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. That is, the mounting brackets 7 and 8, which are the fixtures provided on the angles 4 and 5, move 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 attached to the upper surface of the ceiling material 1. At the same time, the frame 6 is brought into contact with the ceiling material 1.
This is done by sandwiching the ceiling material 1 between the mounting brackets 7, 8 and the frame 6 while coming into contact with the lower surface of the ceiling material. The bowl-shaped reflecting plate 10 is held by a mounting spring (not shown) provided on the side of the horizontal plate 3b. Power supply components such as a ballast 11, a glow bulb 12 to be attached to a glow socket, a lamp socket 14 to which a lamp 13 is attached, and a terminal block 15 to which an external power line is connected are arranged at the rear part 3a of the lighting fixture body 3. There is.

Here, the longitudinal dimension of this lighting fixture body 3 is formed larger than the diameter of the opening 2 formed in the ceiling material 1, and the rear part 3a of the lighting fixture body 3 is connected to the power supply as described above. Because the parts are arranged unevenly, the center of gravity G of the lighting fixture body 3 is
As shown in the figure, it is located on the rear 3a side, and its center of gravity G is offset from the center of the opening 2 of the ceiling material 1. When putting the lighting fixture body 3 into the opening 2, the rear part 3a of the lighting fixture body 3 is first put into the opening 2, and the lighting fixture body 3 is rotated so as to lift the reflector 10 side.

In the case of the above lighting equipment, the lighting equipment body 3
The center of gravity G of
is applied to the center of gravity G. Therefore, as shown in FIG. 5, there is a gap δ between the lower surface of the ceiling material 1 and the frame 6.
There was a problem that this caused light leakage.

[Purpose of the invention] The present invention has been provided in view of the above-mentioned points, and provides a lighting equipment whose purpose is to prevent a gap between the lighting equipment and the lower surface of the ceiling material due to the inclination of the lighting equipment body. be.

[Disclosure of the invention] (Structure) The present invention is a lighting equipment main body whose outer diameter in the longitudinal direction is larger than the diameter of an opening formed in a ceiling material, and whose center of gravity is shifted from the center of the opening. Insert from below the opening, and touch the fixtures provided on both sides of the lighting fixture in a direction perpendicular to the longitudinal direction of the lighting fixture to the top surface of the ceiling material, and attach the frame provided at the bottom of the lighting fixture to the ceiling. In a lighting fixture that is fixed to the ceiling material by sandwiching the ceiling material between the mounting bracket and the frame by coming into contact with the lower surface of the periphery of the opening in the material, what is the center of gravity of the lighting device body? By providing a third fixture that touches the top surface of the ceiling material on the longitudinal line on the opposite side, by sandwiching the ceiling material together with the frame between both fixtures and the third fixture, the lighting fixture body can be The lighting fixture is characterized in that even if the center of gravity is shifted from the center of the opening, the lighting fixture main body is prevented from tilting.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.
The gist of this invention is that in addition to the conventional configuration, angle 1
6 and one set of mounting brackets 17 have been added, making the total number of each set three, and the other configurations are the same as the conventional one, so a description thereof will be omitted. That is, as shown in FIG. 2, the angle 1 is
6 is provided, and the frame 6 is caulked and fixed to the lower part of the angle 16. A groove 18 is formed in the vertical direction of the angle 16, and by moving the mounting bracket 17 up and down in the same way as the mounting brackets 7 and 8 of the other angles 4 and 5, the ceiling material 1
The lighting fixture main body 3 is fixed by sandwiching the . Here, in FIG. 1, the centerline A is the centerline in the longitudinal direction of the lighting fixture main body 3, that is, in the direction that is larger than the diameter of the opening 2 and extends outward from the projection plane of the opening 2. The center line B is an orthogonal axis that is orthogonal to the center line A at the center of the connecting portion 2.

Angles 4 and 5 are placed on the center line B. This is because the weight of the lighting fixture main body 3 is supported by the two mounting fittings 7 and 8. The third angle 16 and mounting bracket 17 are connected to the center of gravity G of the lighting fixture body 3.
It is arranged on the circumference of the lighting fixture main body 3 facing the. In FIG. 1, since the center of gravity G is on the centerline A, the angle 16 and the mounting bracket 17 are attached to the outer periphery of the lighting fixture body 3 on the centerline A. The angle 16 is arranged in a range D on the opposite side of the center of gravity G with respect to the center line B. This is due to the following reasons. That is, FIG. 3 shows how to install the lighting fixture body 3, but as previously explained, since the lighting fixture body 3 is larger than the opening 2 of the ceiling material 1, the opening 2 must first be attached. The rear part 3a of the lighting fixture body 3 is inserted, and then the entire lighting fixture body 3 is constructed while rotating. Therefore, if the angle 16 is outside the range D in FIG. 1, that is, if the angle 16 and the mounting bracket 17 are on the center of gravity G side, they will hit the ceiling material 1 during embedding, making construction impossible. Therefore, angle 16 must be within range D.

When the lighting fixture main body 3 is disposed in the opening 2 of the ceiling material 1, the lighting fixture main body 3 is inserted into the opening 2 from the rear part 3a from below and installed while rotating the lighting fixture main body 3, as in the conventional case. And each angle 4,
Move the mounting brackets 7, 8, 17 of 5, 16 downward, and attach the ceiling material 1 with the mounting brackets 7, 8, 17 and the frame 6.
The lighting fixture main body 3 is placed and fixed in the opening 2 of the ceiling material 1 by inserting it. Therefore, while ensuring ease of installation of the lighting fixture body 3, the mounting bracket 17
By sandwiching the ceiling material 1 with the frame 6, it is possible to prevent a gap between the lower surface of the ceiling material 1 and the frame 6. Furthermore, since the ceiling material 1 fits between the lighting fixture main body 3 and the frame 6, construction can be performed even if the height of the back surface of the ceiling is low.

[Effects of the invention] As described above, the present invention is a lighting fixture body whose longitudinal outer diameter is larger than the diameter of the opening formed in the ceiling material, and whose center of gravity is offset from the center of the opening, In the above-mentioned lighting fixture that is inserted from below the opening and placed on the ceiling surface, the frame that is provided at the bottom of the lighting fixture body is placed in contact with the top surface of the ceiling material and on the lower surface of the periphery of the opening in the ceiling material. Fixtures for fixing the lighting fixture body to the ceiling material by abutting and sandwiching the ceiling material with the frame are provided on both sides of the lighting fixture body in a direction perpendicular to the longitudinal direction of the lighting fixture body. Since the third fixture is provided on the longitudinal line on the opposite side of the center of gravity and touches the top surface of the ceiling material, both fixtures and the third fixture can be used to hold the ceiling material together with the frame. By sandwiching it, even if the center of gravity of the lighting fixture is shifted from the center of the opening, it is possible to prevent the lighting fixture from tilting, thereby reducing the gap between the bottom surface of the ceiling material and the frame. Moreover, since only a third fixture is provided in addition to both fixtures, the lighting fixture body can be securely mounted and fixed without complicating the fixture structure. In addition, by providing the third fixture that touches the top surface of the ceiling material on the longitudinal line on the opposite side of the center of gravity of the lighting equipment body, it is possible to When installing the lighting fixture by inserting it into the ceiling from the center of gravity side, the third fixture can be embedded without hitting the ceiling material, making the embedding operation easy. Moreover, since the fixtures are provided on both sides of the lighting fixture in a direction perpendicular to the longitudinal direction of the lighting fixture, even when replacing a glow bulb, etc. This has the effect of preventing inclination in orthogonal directions.
