Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a multiple fluorescent lamp fixture in which a plurality of lamp bodies are arranged around the fixture body.

[Background of the invention]

In the conventional appliance shown in FIG. 1, a plurality of lamp bodies 3 with ring-shaped fluorescent lamps 2 fixed to the lower side are arranged around an appliance main body 1 that houses a lighting device such as a ballast. In addition, a portion of each lamp body 3 is overlapped around the fixture body 1, making the whole fixture compact. In such a multi-light fluorescent lamp fixture, a glow starter mounting hole 4 and a long hole 5 connected to the glow starter mounting hole as shown in FIG. establish. The glow starter mounting hole 4 is used to lead out the socket 6, and after guiding the electric wire 7 of the socket 6 to the elongated hole 5, the glow starter 8 is attached to the glow starter socket 9 in the appliance main body 1, and the glow starter is installed. Close hole 4.

However, in the above-described multiple fluorescent lamp fixture, the electric wire 7 of the socket 6 can move freely along the elongated hole 5, so when the glow starter 8 is installed, the electric wire 7 may block the glow starter mounting hole 4. There is a drawback that it is difficult to attach the glow starter 8, especially when a multi-light fluorescent lamp fixture is installed, since the user has to extend both hands upward, making it difficult to attach the glow starter 8.

[Purpose of the invention]

The present invention allows easy installation of the glow starter,
Another object of the present invention is to obtain a multi-light fluorescent lamp fixture that is safe and has little heat conduction from the lamp body to the fixture body.

[Summary of the invention]

In the multi-light fluorescent lamp fixture of the present invention, a plurality of lamp bodies each having an annular fluorescent lamp fixed to the bottom surface thereof are partially overlapped and disposed around the fixture body which has a built-in lighting device such as a ballast. This is the type of thing that does.
In such a multi-lamp fluorescent lamp fixture, there is a cutout in a part of the lower surface of the lamp body at a position where each of the lamp bodies overlaps with the main body of the fixture and corresponds to the cap of the annular fluorescent lamp. A cylindrical body with a height reaching near the base is provided, and the inside of the cylindrical body is used as a through hole of the socket.

The opening of this through-hole on the lamp body side is close to the cap, and the cap gets in the way to prevent foreign objects or people's fingers from entering. It also moderates the transfer of heat from the annular fluorescent lamp toward the appliance body.

[Embodiments of the invention]

Embodiments of the present invention will be described using FIGS. 3 to 5. As shown in FIGS. 3 and 5, parts of a plurality of lamp bodies 3, each having an annular fluorescent lamp 2 fixed to the lower surface thereof, are overlapped around a fixture body 1 containing a lighting device such as a ballast. and place it. Translucent cover 1
0 covers the lamp body 3 and the annular fluorescent lamp 2 from below, but this is not essential.

In the present invention, as shown in FIG. 4, a notch 12 is partially formed on the lower surface of the lamp body 3 in an area where the lamp body 3 overlaps with the fixture main body 1 and at a position corresponding to the base 11 of the annular fluorescent lamp 2. A cylindrical body 13 having a height reaching near the base 11 of the annular fluorescent lamp 2 is provided. The inside of this cylindrical body 13 becomes a through hole 14 of the socket 6. In this embodiment, the glow starter socket 9 is attached to the above-mentioned overlapping area on the side of the appliance body 1, and the glow starter mounting hole 15 is provided on the lamp body 3 side in the above-mentioned area, but the attachment position of the glow starter socket 9 is on the above-mentioned cylinder A position other than the body 13 can be freely selected.

In the multiple fluorescent lamp fixture having the above structure, the glow starter mounting hole 15 is connected to the through hole 1 of the socket 6.
Since it is provided separately from the glow starter 4, the glow starter 8 can be easily installed without any obstacles. Further, the socket 6, which has been connected in advance to the lighting device in the appliance main body 1, is led out into the lamp body 3 by passing through the through hole 14 of the cylinder body 13, and the socket 6 is inserted into the lamp body 3 as shown in FIGS. 4 and 5. The electric wire 7 of the socket 6 can be guided through the notch 12 of the socket 6, and the socket 6 can be inserted into the base 11 of the annular fluorescent lamp 2. After the annular fluorescent lamp 2 is led out from the socket 6, it is attached to the lower surface of the lamp body 3.

In the present invention, the annular fluorescent lamp 2 is connected to the base 1.
Since the lower edge of the cylindrical body 13 reaches close to the lamp 1 and the heating of the base 11 is slight, the heat of the annular fluorescent lamp 2 inside the lamp body 3 is difficult to be conducted into the appliance body 1 where the lighting device is located. Also, the cylinder body 13 and the cap 11
Since the gap between the device body 1 and the device body 1 is small and prevents the insertion of a foreign object or a person's finger, there is little risk of contact with the live part inside the device body 1. Furthermore, even when the multi-light fluorescent lamp fixture is looked up from below, the through hole 14, which is the dark part on the side of the lamp body 3, is hidden by the base 11 and difficult to see, resulting in a good appearance.

〔Effect of the invention〕

As described above, in the present invention, there is a cut in a part of the lower surface of the lamp body in the area where each lamp body and the fixture body overlap and at a position corresponding to the cap of the annular fluorescent lamp. A cylindrical body with a height reaching near the base is provided, and the inside of the cylindrical body is used as a through hole for the socket.

In addition to providing an independent through hole other than the glow starter mounting hole as described above, the gap between this through hole and the base of the annular fluorescent lamp is made small to prevent heat inside the lamp body from being conducted into the fixture body. This is effective in reducing heating of the appliance itself or the lighting device inside it. In addition, it is electrically safe because it prevents human fingers or foreign objects from touching the live parts and parts inside the device body.

Therefore, it is possible to obtain a practical multi-lamp fluorescent lamp fixture in which a glow starter can be easily attached.
