Abstract

PURPOSE:To enable connection requiring only a simple operation and having good resistance to heat and weather, by bonding a fluorescent lamp on a support body using polyamide group adhesives. CONSTITUTION:A support body 3 takes a U-shaped form and is stuck to a metal cap 2 with open leg sections 31 and 32 facing downward. For example, opened annular support sections 34 and 35 that support a lamp 4 and a glow tube 6 are provided on the external surface of one leg section 31 and a proper fixing member 36, for example, a support ring that supports another section of the lamp 4 is provided on the external surface of the other leg section 32 and then a stabilizer 7 is supported between the legs. To stick these fluorescent lamp 4 and glow tube 6 to the support body 3, both tube end sections 41 and 42 of the lamp 4 are inserted in the support sections 34 and 36 and preheated melted hot-melt type polyamide group adhesive 5 is poured in the gap between the lamp 4 and the support section, cooled, solidified, and bonded. As a result, connection can be performed with a simple operation and with good resistance to heat and weather.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a fluorescent lamp device in which a fluorescent lamp is housed in a glove together with a lighting member such as a ballast.

[Technical background of the invention]

A compact fluorescent lamp with a good appearance, in which a conventionally curved saddle-shaped fluorescent lamp is fixed to a support and housed in a spherical globe together with lighting components such as flashers, lighting tubes, and ballasts. The device is known.

[Problems with background technology]

Since the globe is small, the temperature inside the globe increases significantly due to the heat generated from the lamp and lighting components. For this reason,
The means for securing the lamp to the support must have sufficient heat resistance. However, mechanical coupling means require expensive parts and a lot of labor, and have the disadvantage of being expensive.

However, conventional adhesives have the disadvantage of poor heat resistance and weather resistance, and may peel or discolor, resulting in loss of marketability.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a fluorescent lamp device that is easy to connect a fluorescent lamp to a support and has excellent heat resistance and weather resistance.

[Summary of the invention]

By adhering the fluorescent lamp to the support using a polyamide adhesive, it is possible to achieve a bond with excellent heat resistance and weather resistance with a simple operation.

[Embodiments of the invention]

The details of the invention will be explained by means of illustrated embodiments.

(1) is a spherical globe, (2) is an E-type cap provided at the top end of the globe (1), (3) is a support connected to the cap (2) and suspended inside the globe (1), ( 4) is a saddle-shaped fluorescent lamp attached to this support (3), (5) is a polyamide adhesive that adheres this lamp (4) to the support (3), and (6) is a support (3). ) is fixed to the lamp (4)
The lighting tube (7) is a part of the lighting member that lights up the lamp, and (7) is the ballast that is the other part of the lighting member fixed to the support (3).

The above-mentioned globe (1) is split into two parts, with a non-translucent top hemisphere (11) and a translucent bottom hemisphere (1) removably connected to the top hemisphere (11). ), and both hemispheres ([1), 0 and 0 vent holes (13),
(14) is provided.

The support body (3) has a U-shape, and has open legs G υ, (3
It is fixed to the cap (2) with the tip facing downward. Then, attach the lamp (4) and the lighting tube (
5), for example, an open ring-shaped support part (34) that supports C3
4), G (5) on the other leg (32) and the lamp (4) on the outside.
A suitable fixing member (g) such as a support ring is provided to support the other parts, and a stabilizer (7) is supported between the legs.

The fluorescent lamp (4) has a so-called saddle shape in which two U-shapes are connected, both tube ends (41), (4υ is the support part t34 of one leg Gυ of the support body (3)), C34 ) and
The folded part (the folded part) is fixed to the fixing member (sa) of the other leg. Also, the lighting tube (6) is attached to both ends of the lamp (4) (4υ, (in the middle of the Glue the outer conductors (c) and (4) of the lamp (4).
and the outer conductor (61) of lighting %f (6), (6i
) are connected as specified.

As mentioned above, in order to fix the fluorescent lamp (4) and lighting tube (6) to the support (3), first attach both tube ends (41), (4υ) of the lamp (4) to the support. (34), C34) and pre-heated and melted polyamide adhesive (5
) is poured into the gap between the lamp (4) and the support part (b) and allowed to cool and solidify, then the lamp (4) becomes the support part 04), 04).
is glued to. Further, the lighting tube (6) is also bonded to the support portion C3ω in a similar manner. Furthermore, the folded portion (1) of the lamp (4) is fixed by the fixing portion 43 (36).

Polyamide adhesives usually belong to the hot-melt type, and may be melted by heating and injected into the area to be bonded as described above, or alternatively, a welding agent formed into a sheet or the like is interposed in the area to be bonded and heated. De-based adhesives generally have a high softening temperature and do not become brittle after long-term use.
When a fluorescent lamp (4) with a relatively large output is housed in a small globe (1) as in this embodiment, the globe (
1) Resistant to high temperatures and will not peel off. According to experiments, if this type of adhesive with a softening temperature of 120° C. or higher was selected and used, it could sufficiently withstand high temperatures in summer. Furthermore, for use in higher temperature locations, an adhesive with a higher softening temperature may be used. Furthermore, there is no risk of deterioration or discoloration of the polyamide adhesive due to ultraviolet rays, and even after long-term use, it will not peel off or crack due to the ultraviolet rays leaking from the lamp (4), and its adhesive strength will not decrease, and it will not discolor. There is no decrease in product value due to this.

In the above embodiment, the adhesive was injected after the fluorescent lamp was inserted into the annular support part of the support, but the annular support part is not essential in the present invention, and the fluorescent lamp was directly adhered to the side surface of the support. It's okay.

In the above-mentioned embodiment, the fluorescent lamp is bent into a saddle shape, but this is to make the globe smaller; the present invention is not limited to this, and may be shaped into a U-shape, an O-shape, etc.
In short, it is suitable for fluorescent lamp devices where the inside of the glove becomes high temperature.

Further, instead of the lighting tube, a lighting member of another lighting method such as a high frequency lighting circuit may be used.

〔Effect of the invention〕

In the fluorescent lamp device of the present invention, the lamp is bonded to the support using a polyamide adhesive and housed in the globe together with the lighting member, so the bonding time is short, manufacturing is easy, and it is heat resistant after bonding. Since it is highly weather resistant, it can withstand high temperatures inside the glove and leaked ultraviolet rays and has a long life, and does not discolor, so it has the advantage of being highly marketable without degrading its appearance.
