Description

[Detailed description of the invention] [Technical field] The present invention relates to a ceiling-mounted lighting fixture in which electromagnetic waves generated from lamps, ballasts, etc. are shielded by a shield panel attached to the bottom of the lighting equipment body. be.

[Background technology] Electromagnetic waves are generated from lamps, ballasts, etc. installed inside lighting equipment, so medical equipment,
It has a negative impact on computer-related equipment, etc. Therefore, in order to reduce the noise caused by the electromagnetic waves, a metal wire mesh 8 has conventionally been attached to the lower opening of the lighting fixture as shown in FIG. That is, by protruding the receiving piece 7 from the inner surface of the panel frame 2 that is attached to the lower opening of the lighting fixture main body 1,
A semi-transparent panel 6 is placed on the receiving piece 7, and a wire mesh 8 is placed on this panel 6.
and a metal main body 1 are connected by a grounding lead wire 9. However, in this structure, the panel 6 is mounted on the panel frame 2 and the main body 1
, the lead wires 9 will rest on the panel 6, which causes the shadow of the lead wires 9 to be visible from below when the lamp is lit, making it very unsightly, and when replacing the lamp 20. Since the wire mesh 8 and the main body 1 are connected by lead wires 9, it is not possible to completely remove the panel frame 2 from the main body 1, and the lamp 20 cannot be removed while the panel frame 2 is being held.
Therefore, it was difficult to replace the lamp 20. In the figure, 10 indicates the panel frame as main body 1.
frame fixture formed of spring material to be attached to, 19
is a locking piece fixed to the inner surface of the main body 1.

[Purpose of the invention] The present invention was developed in view of the above points, and is intended to reduce the electromagnetic noise from lighting equipment without causing the shadow of the grounding lead wire to be cast on the panel. The object of the present invention is to provide a lighting device that is not unsightly in appearance and whose lamps can be easily replaced.

[Disclosure of the Invention] That is, the lighting fixture of the present invention includes a spring receiver 3 attached to a panel frame 2 attached to a lower opening of a lighting fixture main body 1, and a spring member 4 that elastically urges the spring receiver 3 downward. A panel 6 with a conductive part 5 formed on the inner surface is mounted inside the panel frame 2, and the lower end of the spring material 4 is brought into elastic contact with the conductive part 5, so that the spring material 4 and the spring receiver 3 are electrically conductive. The conductive part 5 of the panel 6 is formed of a material and electrically connected to the lighting fixture main body 1 via the spring material 4 and the spring receiver 3. By electrically connecting to the main body 1 via the spring holder 3, the conventional lead wire 9
This eliminates the need for the above objective.

The present invention will be described in detail below based on illustrated embodiments. First, the spring receiver 3 will be explained. As shown in FIG. As well as hanging down, the horizontal piece 1
A spring stopper 13 is bored at both ends of 1, and a mounting piece 14 is formed to protrude upward from the hanging piece 12. The spring member 4 is made of a conductive material such as an elastic metal plate, and is formed by providing stop pieces 16, 16 at both ends of a central spring portion 15. Both retaining pieces 16, 16 of this spring member 4 are engaged in spring retaining parts 13, 13 of the spring receiver 3, and the spring part 15 protrudes downward from the horizontal piece 11. The frame fixture 10 is made of a spring material that allows the dimension between the two locking portions 17, 17 to be widened or narrowed. Furthermore, the panel 6 is a so-called shield panel.
As shown in FIG. 2, a transparent or semi-transparent substrate 2
A conductive portion 5 made of conductive ink is coated on the inner surface of the conductive portion 2 in a net shape. A conductive part 5 is applied around the entire circumference of the panel 6. Next, when attaching the panel 6 to the panel frame 2,
As shown in FIG. 2, the panel 6 is arranged within the panel frame 2, the peripheral edge of the panel 6 is placed on the receiving piece 7 of the panel frame 2, and the spring receiver 3 is placed on the inner surface of the panel frame 2. The hanging piece 12 is attached, and the panel 6 is elastically held between the spring portion 15 of the spring member 4 and the receiving piece 7. The spring portion 15 of the spring material 4 comes into elastic contact with the conductive portion 5 around the panel 6. Both locking parts 17, 17 of the frame mount 10 connected to the mounting piece 14 of the spring receiver 3 via the mounting bracket 18 can be freely removed by the locking piece 19 fixed to the inner surface of the lighting fixture body 1. It locks in.

Therefore, the conductive part 5 made of conductive ink of the panel 6 includes the spring material 4, the spring receiver 3, and the mounting bracket 18.
It is electrically connected to the lighting fixture main body 1 through the frame mount 10, and the main body 1 can be grounded through these conductive materials. There is no need to remove the panel frame 2, and therefore it does not look unsightly even after the panel frame 2 is attached to the main body 1. Furthermore, since the panel 6 is elastically held between the spring material 4 of the spring holder 3 and the receiving piece 7 of the panel frame 2, the panel 6 flies up when the panel frame 2 is attached to the main body 1. In addition, even if the thickness of the panel 6 changes slightly, it can be absorbed by the elasticity of the spring material 4, and the installation of the spring receiver 3 to the panel frame 2 is possible. This can be accommodated without the need for design changes such as changes in position. Now, when replacing the lamp 20 inside the main body 1, simply use the elasticity of the locking part 17 of the frame mount 10 to replace the main body 1, just like in the case of a general ceiling-embedded lighting fixture. Locking piece 1
This can be done by removing it from 9, and the workability is good. Furthermore, even when replacing the panel 6 due to damage, etc., the panel 6
is not completely fixed to the panel frame 2 with screws or the like, but is only held down by the spring material 4, so it is extremely easy to replace the panel 6 by moving the panel 6 to the side. can be done.

As shown in FIGS. 3 and 4, a cut-and-raised piece 21 is cut and raised from the hanging piece 12 of the spring receiver 3, and the end of the panel 6 is placed on the upper surface of this cut-and-raised piece 21. However, the peripheral end of the panel 6 may be elastically held between the cut and raised piece 21 and the spring material 4. In this way, the vertical positioning of the panel 6 can be automatically performed, and the reliability of the electrical connection between the panel 6 and the spring material 4 can be improved. Furthermore, although a plate spring was used as the spring material 4 in the above embodiment,
As shown in FIG. 5, a spring spring may be used as the spring material 4.

[Effects of the invention] As described above, in the present invention, a panel with a conductive part formed on the inner surface is attached to the lower opening of the lighting fixture body, and this conductive part is electrically connected to the main body. It goes without saying that the panel can prevent electromagnetic wave noise from lamps and ballasts, etc., but it is also possible to mount the panel within the panel frame and bring the lower end of the spring material into elastic contact with the conductive part. Since the holder is made of a conductive material and the conductive part of the panel is electrically connected to the lighting fixture body via the spring material and the spring holder, there is no need for a grounding lead wire as in the past. There is no shadow of the lead wires cast on the panel, so it does not look unsightly, and even when replacing the internal lamp, the panel frame can be completely removed from the main body, making it easy to replace the lamp. It is.
