Abstract

PURPOSE:To enable connection with a simple operation and with good resistance to heat and weatherability by bonding a fluorescent lamp on a support body using ultraviolet rays curing type adhesives. CONSTITUTION:A fluorescent lamps 4 takes a saddle form in which two U- shaped forms are connected and both tube end sections 41 are bonded and fixed with adhesivs 5 along a support body 3 and then a folded section 42 is also bonded on the reverse surface of the support body 3 with the adhesives 5. In addition, a glow tube 6 is bonded on the support body 3 with the adhesives 5 on the way to both tube end sections 41 of the lamp 4. These adhesives 5 use silicon resin group or deformable acrylate resin group adhesives and are cured by the ultraviolet rays irradiation. After curing, the adhesives are changed into ultraviolet curing type adhesives that are transparent, have good resistance to heat, do not generate cracks and exfoliation even if they are heated at high temperatures of 160 deg.C for a long period of time depending upon the item, and do not change the color.

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]

This is a compact and good-looking fluorescent lamp in which a conventionally curved saddle-shaped (C) lamp is fixed to a support and housed in a spherical globe together with lighting components such as a blinker, a dot tube, and a ballast. Lamp devices are 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 requires expensive parts and a lot of labor, and has 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 bonding the fluorescent lamp to the support using an ultraviolet curable adhesive, it is possible to achieve a bond with excellent heat resistance and 110' 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 mounted 2i 4"l on this support (3), (
5) is an ultraviolet curable rock contact agent that attaches this lamp (4) to the support (3), and (6) is a part of the lighting member that is fixed to the support (3) and lights the lamp (4). Light tube, (7
) is the ballast, which is another part of the lighting unit fixed to the support (3).

The above-mentioned glove (1) is split into two parts, with a non-transparent top hemisphere (11) and a translucent bottom hemisphere a-shaped, which are freely combined with a stone surface, and a cap (2) on the top hemisphere side. Both hemispheres (11) and (1'lt both have ventilation holes (1, 3)
, (14) is provided.

The adhesive (5) is, for example, a silicone resin-based or modified acrylate resin-based adhesive that is cured by UV irradiation, and is transparent after curing and has heat resistance (= depending on the product, it can be heated for a long time at a high temperature of 160°C). No cracking or peeling occurs, and no discoloration occurs.

The fluorescent lamp (4) has a so-called saddle-shaped structure in which two U-shapes are connected, and both tube ends G111, (4) are attached to a support (
3) and fix it with adhesive (5), and the folded part (42) (6) is also attached to both tube ends (41) of the lamp (4).
1, (411) is bonded to the support (3) with a suitable adhesive, such as the above-mentioned ultraviolet curing adhesive (5).Then, the outer conductor (43,
(43 and external force on lighting tube (6), line (61), (61
) are connected as specified.

To secure the lamp (4) to the support (3), use the lamp (4)
), both tube ends (41), (41) and folded part (42) are aligned with the opposite side of the support (3), and UV-curable adhesive HF'+41 (5) is attached to the part to be bonded. It can be cured by irradiating it with ultraviolet rays. Similarly, light tube (
6) is also fixed to the support (3).

This fluorescent lamp device has a simple structure and can be manufactured at low cost since the lamp (4) is fixed with an adhesive (5).

In addition, since the adhesive (5) is UV-curable, there is no risk of natural curing, so the number of times the adhesive (5) is supplied to the supply device is small, and cleaning is easy, so maintenance effort is reduced. Furthermore, since the adhesive (5) has high heat resistance, it can withstand the high temperatures inside the glove (1) and has a long life.Furthermore, the adhesive (5) does not discolor due to heat or light, so the product has a good appearance. Highly sexual.

In the above-mentioned embodiment, the fluorescent lamp was curved into a saddle shape in order to make the glove smaller; however, the present invention is not limited to this, and may be shaped into a U-shape, a O-shape, etc.
In short, it is suitable for lamp devices where the inside of the globe becomes hot.

Further, other types of lighting members such as a high frequency lighting circuit may be used instead of the lighting tube. Furthermore, the heat resistance of the adhesive is 12
If it can withstand temperatures above 0°C, it can also withstand normal summer high temperatures.

〔Effect of the invention〕

The fluorescent lamp device of the present invention has a lamp adhered to a support and housed in a globe together with a lighting member, and since the lamp is adhered to the support using an ultraviolet curing adhesive, it is easy to manufacture. It is easy to maintain the production equipment, and after bonding, it is highly heat resistant, so it can withstand the high temperatures inside the glove and has a long life.Furthermore, the adhesive does not discolor due to heat or light, so it has a good appearance and is a good product. It has a high advantage.
