Description

[Detailed Description of the Invention] Industrial Fields of Application The present invention provides a case in which a fluorescent lamp, a ballast, a starter, etc. are built into an envelope with a cap similar to that of an incandescent light bulb protruding from the envelope, and the bulb can be directly inserted into an incandescent light bulb socket. This invention relates to a light bulb base type fluorescent lamp that is configured so that it can be mounted and lit.

BACKGROUND TECHNOLOGY In general, a conventional light bulb base type fluorescent lamp is constructed as shown in FIG. Inside the enclosure, there is a double U-shaped fluorescent lamp 4,
A ballast 5, a glow starter 6, etc. are housed therein. However, the cover 2 and the glove 3 are integrally joined by an adhesive layer 7 at their mutual fitting portions, and there is a non-transparent space inside the envelope that partitions the internal space of the cover 2 and the internal space of the glove 3. A cup-shaped holder 8 is provided so that its inner surface faces the cover 2. The holder 8 has a lamp end socket 9 and a glow starter supporting protrusion 10 on its outer surface, and supports and fixes the ballast 5 on its inner surface. Reference numeral 11 indicates a noise prevention capacitor connected to the glow starter 6.

In the conventional light bulb cap type fluorescent lamp configured as described above, the fluorescent lamp 4, the ballast 5 and the glow starter 6 can be stably supported by the common holder 8. When fixing the device to the holder, firm fixing using screws or grommets was required in consideration of noise generation and heat dissipation effects, which required difficult fixing work and a sturdy holder. Furthermore, if the glove 3 is made of highly transparent material, the glow starter 6 and the supporting protrusion 10 may seep into the eye through the glove 3.
This will damage the appearance and product value. Furthermore, since the electrical components are installed separately on the outer and inner surfaces of the holder 8, electrical wiring must be routed through the through holes provided in the holder 8, which is a hassle during the assembly process.

Problems to be Solved by the Invention Therefore, it is an object of the present invention to be able to firmly fix the ballast to the inner surface of the holder without using screws or grommets, and with good heat dissipation, and to also fix the ballast to the inner surface of the holder with good heat dissipation. An object of the present invention is to provide a light bulb base mold type fluorescent lamp which can also house the inside surface of a holder.

Means for Solving the Problems According to the present invention, an end socket for a fluorescent lamp is provided on the outer surface of a holder fixed in an envelope, while a ballast and a starter are accommodated on the inner surface. A chamber is provided, and the stabilizer is fixed within the chamber using silicone resin.

Function Since the present invention is configured as described above, the stabilizer can be fixed relatively easily and firmly to the holder without using screws or grommets, thereby suppressing noise generation due to vibration of the core of the stabilizer. be able to. Further, since the silicone resin has good thermal conductivity, the heat generated by the stabilizer is efficiently transmitted to the holder and the envelope through the silicone resin, and a good heat dissipation effect can be obtained. Furthermore, it is now possible to provide a starter housing adjacent to the ballast housing, which not only simplifies wiring work, but also allows the starter, its fixing protrusions, and noise prevention capacitors to be placed in the glove compartment. It is no longer visible through the glass, and the appearance and commercial value can be improved.

Embodiment As shown in FIGS. 1 and 2, a non-transparent cup-shaped cover 2 with a base 1 protruding thereon is made of a transparent cup-shaped cover 2 bonded with an adhesive layer 7 made of silicone resin or the like. An opaque cup-shaped holder 12 forms an envelope together with the sexual glove 3 and partitions the internal space of the cover 2 and the internal space of the glove 3.
is fixed to the inner surface of the envelope with an adhesive layer 7 so that its inner surface faces the cover 2. The holder 12 has two cylindrical end sockets 9 on the outside for supporting the ends of the double U-shaped fluorescent lamp 4 provided in the globe 3, and a housing chamber 13 for the ballast 5. It also has a storage chamber 14 for the glow starter 6 on its inner surface.

The stabilizer 5 in the storage chamber 13 is fixed to the holder 12 by thermosetting silicone resin 15 injected into the storage chamber 13 . The starter 6 in the storage chamber 14 is held between two parallel partition walls that form the storage chamber 14 . Further, as shown in FIG. 3, a through hole 16 is formed at the bottom of each of the two end sockets 9, through which the evacuation thin tube part of the fluorescent lamp 4 and the lead wire are inserted. .

Effects of the Invention According to the present invention, as mentioned above, not only the work of fixing the ballast to the holder and the wiring work are facilitated, but also the generation of noise from the ballast can be suppressed, and the heat dissipation of the ballast can be reduced. If it is in good condition, it can be shown. Further, even if the glove is highly transparent, the starter etc. cannot be seen through, and the appearance and commercial value can be improved.
