Description

[Detailed Description of the Invention] [Technical Field] This invention relates to a built-in lighting fixture, particularly to the structure of a reflector mounting portion.

[Background technology]

Reflector mounting part 1 of conventional built-in lighting fixture 1'
a' had a structure as shown in FIG. 3a. That is, in the lighting fixture mounting hole 3 provided in the ceiling 2,
A box-shaped yoke 5 opening downward is embedded, and a reflecting plate 6 is attached to the inside of the yoke 5 with mounting screws 7. In the case of a two-lamp lighting device, the reflector 6 has a central portion 6a formed in a chevron shape as shown in the figure, and a splint plate 9' is provided integrally with the reflector 6 above the central portion 6a. There is. The splint plate 9' is
When the reflector 6 is attached to the yoke 5, its upper part comes into contact with the lower end of the positioning plate 10 that projects downward from the yoke 5, thereby determining the vertical position of the reflector 6. .

By the way, in the conventional lighting device 1', when the reflector plate 6 was attached, if the mounting screw 7 was tightened more than a predetermined amount, the reflector plate 6 was bent and deformed as shown in FIG. 3B. Such deformation is not only undesirable as it causes unreasonable force on each part of the reflector 6, but also creates a gap 11 in the connecting part when the reflector 6 is connected vertically, as shown in FIG. cause it to occur.

[Purpose of invention]

This invention was made in view of the above-mentioned circumstances, and aims to provide an embedded lighting fixture in which the reflector does not deform during installation.

[Disclosure of invention]

The recessed lighting equipment according to this invention includes a yoke that is embedded in the ceiling, a reflector that is placed below the yoke and attached to the yoke with mounting screws, and a reflector that is integrated with the reflector above the reflector. In the recessed lighting fixture, the recessed lighting device is provided with a splint that comes into contact with a positioning plate that protrudes from the lower surface of the yoke when installed, and on the top of the splint,
The present invention is characterized in that a protrusion inscribed in the positioning plate is provided. The embodiments shown in the drawings will be described below.

FIGS. 1a and 1b are a cross-sectional view of an example of a built-in lighting device according to this invention and an enlarged view of its essential parts.
This lighting fixture 1 includes a yoke 5 and a reflector 6 similar to those of the conventional example 1', and the reflector 6 is attached by inserting mounting screws 7 into the yoke 5 from the reflector 6 side. The reflecting plates 6 are provided by connecting a plurality of reflecting plates 6 in the vertical direction, as shown in FIGS. 2a and 2b, by overlapping the connecting portions 6a provided at the ends with the ends of adjacent reflecting plates 6. And York 5
A fluorescent lamp 13 is attached to sockets 12, 12 provided at both ends of the lamp.

Further, a U-shaped positioning plate 10 is provided in a recess 15 formed in the center of the yoke 5, with its center 10a fixed to the recess 15.
Both side portions 10b, 10b of the positioning plate 10 are protruded downward. On the other hand, splint plates 9, 9 are provided integrally with the reflector 6 on both upper slopes of the central portion 6a, respectively. The splint plates 9, 9 have protrusions 9a, 9a inscribed in the side parts 10b, 10b of the positioning plate 10 on the inside of their respective upper ends. The protrusions 9a, 9a are
The outer surface is inclined by an angle θ,
Further, its tip protrudes beyond the top of the reflector by a length l.

In this way, since the splints 9, 9 are provided with the protrusions 9a, 9a that are inscribed in the positioning plate 10, the central portion 6a of the reflector 6 is prevented from deforming in the opening direction, and as a result, the reflector 6 is prevented from deforming in the opening direction. Overall deformation is prevented. Therefore, in the state shown in Figure 1a,
The mounting screw 7 cannot be tightened any further. Furthermore, the reason why the protrusions 9a, 9a are sloped is to prevent the protrusions 9a, 9a from being inserted into the space between the side parts 10b of the positioning plate 10 when the reflecting plate 6 is attached. This is to make it easier. Because of the protrusions 9a, 9a, the reflector 6
The horizontal position can now be easily determined, improving assembly work efficiency.

This type of lighting equipment is packaged in a cardboard box or the like in a disassembled state and transported.
If the portions a and 9a are provided, these portions can be fixed by being stuck into cushioning cardboard, styrofoam, etc., thereby preventing displacement during transportation.

[Effect of idea]

As is clear from the above description, in the embedded lighting fixture according to this invention, the reflector is not deformed due to excessive tightening of the reflector mounting screw.
