Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fluorescent lamp device, and particularly to a fluorescent lamp device with a built-in lighting device that can be used as is by being directly attached to a light bulb socket.

2. Description of the Related Art Conventionally, a fluorescent lamp device is known in which an annular fluorescent lamp and its lighting device are housed in a plastic globe, and a light bulb base is further attached to the globe.

However, this type of device is constructed by combining parts used in commercially available fluorescent lamps and fluorescent lamp fixtures, and has a complex structure and requires a large number of manufacturing steps. However, it was also easy to increase the size.

This invention uses an annular fluorescent lamp without a base and a lighting tube, and the lighting tube is placed between both ends of the annular fluorescent lamp to effectively utilize the internal space of the globe and reduce its size. At the same time, it reduces manufacturing man-hours, simplifies the structure, and solves the problems of conventional products as described above.

An embodiment of the fluorescent lamp device according to the present invention will be described below.
This will be explained in detail using the drawings.

FIG. 1A is a partially cutaway side view of this embodiment, and FIG.
is a partially cutaway front view thereof.

In Figure 1, a metal base 1 finished with white paint is shown.
An E26 type cap 2 is attached to the top of the holder.

A cap fitting 4 made of a substantially inner cylindrical insulator having a flange at the lower end is screwed into the inside of the cap shell 3 of the cap 2. The cap shell 3 is fixed to the billing fixture 4 by caulking the portion of the cap shell 3 corresponding to (1).

Then, the cap fixture 4 is attached to the base 1 by the driving rivet 5.
The cap 2 is firmly attached to the base 1.

The stabilizer 6 has two rivets 7 inside the central part of the base 1.
In addition, there are three leaf springs (hereinafter referred to as leaf springs) 8 for holding the annular fluorescent lamp and fixing the globe at intervals of 120° on the inner side of the periphery.
・It is installed by 9.

Each leaf spring 8 has a shape as shown in FIG.
A first piece 10 that is in contact with the back side of the base 1 and is fixed to the rivet 1 by 9, and
A second piece 11 and a third piece 12 are bent at right angles to the same direction and a fourth piece 1 is bent outward from the third piece 12 at right angles to the third piece 12.
It consists of 3.

The tip of the second piece 11 is slightly bent inward, and has a cut-and-raised piece 14 formed so as to widen outward.

The fourth piece 13 is curved along the curved surface of the annular fluorescent lamp 15.

The annular fluorescent lamp 15 is a small 10W lamp without a cap, and is bonded to the fourth piece 13 of the leaf spring 8 with an ultraviolet curing adhesive (not shown).

The ballast 6 will be placed inside the ring of the annular fluorescent lamp 15.

Furthermore, a plastic holding stand 18 for holding a lighting tube 16 without a cap and a noise prevention container 17 is fixed to the base 1.

As shown in FIG. 3, the base 1 includes a second cut-and-raised piece 19 and a second cut-and-raised piece 20 that are cut and raised at right angles to each other.
It has

On the other hand, the holding base 18 is formed with grooves (not shown) into which the cut and raised pieces 19 and 20 are respectively fitted, and the first and second cut and raised pieces 19 and 20 are fitted into these grooves. 20 are fitted to each other, thereby fixing the holding base 17 to the base 1.

A holding stand 18 holding the lighting tube 16 and the noise prevention capacitor 17 is arranged between both ends of the annular fluorescent lamp 15, as shown in FIG. 1B.

A plastic glove 21 is attached to the underside of the base 1.

Three rectangular locking holes 22 are formed in the side wall of the globe 21 at intervals of 120 degrees, and the side wall of the base 1 and the second piece 11 of the leaf spring 8 placed opposite thereto are formed. The position of the locking hole 22 of the glove 21 is located between the second piece 1
1, push the side wall of the glove 21 against the spring force of the cut and raised piece 14 of the second piece 11, and insert the second piece of the leaf spring 8 into the locking hole 22 of the glove 21. The globe 21 is attached to the base 1 by inserting the 11 cut and raised pieces 14.

Once the glove 21 is attached to the base 1, the locking hole 22 of the glove 21 is hooked to the cut and raised piece 14 of the second leaf spring 8 and the piece 11, so that the base 1
It becomes impossible to remove the glove 21 from the holder.

As described above, since the fluorescent lamp device according to the present invention uses an annular fluorescent lamp and a lighting tube without a base, the lead wires can be used as they are to connect the components, and Since both have no base, they have the advantage of being able to significantly reduce manufacturing man-hours and having a simple structure.

Since the annular fluorescent lamp has no cap, the lighting tube can be placed between both ends of the annular fluorescent lamp, and the ballast can be placed within the annular fluorescent lamp, so that the device can be significantly miniaturized.
