Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a novel incandescent light bulb mount and an incandescent light bulb using the mount.

[0002]

2. Description of the Related Art Generally, an incandescent light bulb mount (M ') is formed by connecting a power supply connector (3') to a lead portion (2 ') drawn from a filament body (1'). The filament (F ') and the power supply connector (3') are made of tungsten, and they are connected by various methods. In case of connection by spot welding (see Fig. 30 ), filament
When (1 ') is a double coil, the end (4') of the power supply connector (3 ') is placed on the lead (2') with the core wire (13 ') still inserted.
Wound, energize while sandwiching from both sides with spot welding electrodes (15 ') while applying pressure, and then joining both, then the single coil core wire (13') and double coil core wire (14 ') It was made to elute in.

However, the joining of tungsten by spot welding is not a fusion welding but a so-called mechanical joining, and the joining portion may come off due to vibration during use. There was a case where the joint portion was weakened and the lead portion (2 ′) was broken from the portion due to vibration during use. In such a case, as shown in Fig . 29 , the protective coil (16 ') is wound around the joint portion prior to spot welding, and the joint portion has a neat shape. I couldn't do it. In addition, when the mount (M ') is formed by spot welding, stress is applied to the filament (F'), which may cause the filament body (1 ') to warp or bend, resulting in a bad appearance. It was not suitable for the special incandescent light bulb described later.

In addition, when spot welding is performed, since the joint portion is pressed, if the lead portion (2 '), which is the joint portion, is flushed, it cannot withstand the applied pressure and is disconnected. Therefore, as shown in FIG. 31 , the protective coil (17 '), which is a separate body, is fitted into the lead portion (2') so that only the lead portion (2 '), which is the joint portion, is not flushed, and a protective member having a large heat capacity is provided from above. Flushing stick (18 ') sandwiched between (26')
There is a problem that it takes a lot of time and labor to attach the filament to the filament main body (1 ') to flush it. In this case, if the lead part (2 ') is not properly held, the lead part (2') will be deformed by flushing, and the lead part (2 ') will be straight when the mount (M') is assembled. As described above, the deformation of the lead portion (2 ') has become a serious problem especially in the case of a special incandescent light bulb as described below.

[0005] Infrared ray-cutting incandescent lamps (= infrared rays, which have been rapidly used these days, prevent part of infrared rays from being radiated to the outside by reflecting a part of the infrared rays with the multilayer coating. In the case of a special incandescent light bulb that is made to pass through, an example of which is shown in FIGS. 29 and 32 ), the infrared ray (20 ') reflected by the coating layer (19') effectively activates the filament body (1 '). The filament body (1 ') must be held in the center of the envelope (8b') so that it can be reheated. Lead part as above (2 ')
The filament body (1 ') does not come to the center of the envelope (8b') in the mount (M ') that uses the deformed filament (F') or the warped or bent filament (F '). It was not suitable for such applications.

As another method of connecting the filament (F ') and the power supply connector (3'), a lead portion (2 ') wound in a coil shape is used.
A part of the
2 ') is made, the locking part (3k') of the power supply connector (3 ') is inserted from this gap (22'), and the lead part is inserted at the power supply connector (3 ').
The method of hooking (2 ') is also widely adopted, but in the case of this method, there is a problem that the length (L') of the mounting portion becomes long and the length of the entire incandescent light bulb becomes too long. In particular, P
After the introduction of the L method, in a reflector type lamp using an incandescent lamp, there is a tendency that a protective glass is fitted into an opening of the reflector, and when the entire incandescent lamp is long, the entire lamp becomes too large and disliked. .

[0007] Also, the filament (F ') and the power supply connector
Since the joint with (3 ') has the above-mentioned structure, it has no choice but to rely on human labor, and there is a problem that it is very inefficient.

[0008]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems of the conventional example. (A) To make it possible to perform flushing including a lead portion even in the case of a filament having a lead portion. , (B) Minimize the length of the joint between the filament and the power supply connector so that the total length of the incandescent lamp can be shortened, and (c) improve the appearance of the joint between the filament and the power supply connector. To improve the vibration resistance, (d) in single-ended incandescent light bulbs, the filament position should be easily and accurately located in the center of the envelope, (e) the filament and the power supply connector It is possible to automate joining.

[0009]

[Means for Solving the Problems] The incandescent light bulb mount (M) according to "Claim 1" is "the end of the filament main body (1) which is spirally wound and entirely flushed.
Or, the lead part (2) pulled out from the end of the filament body (1) where the entire part including the lead part is flushed.
The connection part (4) formed by spirally winding at one end of the power supply connector (3) is fitted on the outside of the connection part (4).
An incandescent light bulb mount (M) in which a part of the above is welded to the end of the filament body (1) or the lead (2), and the connecting portion (4) of the power supply connector (3) and the filament body (1 ) End or the lead part pulled out from the filament main body (1)
The melting part (10) with (2) is the end of the filament body (1) and
Separate from the inserted end of the connecting part (4) where the lead part (2) is inserted.
Connection portion in a case that is part of (4), wherein the insertion end
From the melted portion (10) to the unmelted portion of the connecting portion (4) is the end portion of the filament body (1) or the unmelted portion of the lead portion (2)
It overlaps with the minute (10a) '',
The incandescent light bulb mount (M) according to "claim 2" is "wound in a spiral shape, and the entire end including the flashing filament body (1) or the lead part (2) Inside the lead part (2) pulled out from the end of the filament body (1) where the
Fitting the connection part (4) formed at one end of (3), the connection part
Part of (4) is the end of the filament body (1) or the lead part
An incandescent lamp mount (M) welded to (2) , which is pulled out from the connection part (4) of the power supply connector (3) and the end of the filament body (1) or the filament body (1). The fused part (10) with the lead part (2) is the end of the filament body (1).
Away from the insertion end of the connection part (4) inserted in the lead part or lead part (2)
The insertion end , which is a part of the connection part (4)
From the melted portion (10) to the unmelted portion (10a) of the connection part (4)
Does not melt the end of the filament body (1) or the lead (2) .
It is characterized by the fact that it is overlapped with the fused portion . "

According to this, the end portion of the filament main body (1) or the connecting portion (4) between the lead portion (2) pulled out from the end portion of the filament main body (1) and the power supply connector (3) Since the connection is due to welding, mechanical pressure such as spot welding is not applied to the joint part, stress does not occur in the filament body (1) due to the deformation of the joint part and the joint part, especially the filament body There is no warping or bending in (1), and the mount can be assembled in a straight state of being rolled up. Weld the discharge electrode to the connection
(D) is brought into close proximity, an arc is generated between the discharge electrode (D) and the connection part, and the connection part may be melted, or the connection part may be irradiated with a high-energy laser. .

Moreover, since the joining is done by welding, no pressure is applied to the joining portion such as spot welding, so that even if the connecting portion is flushed, there is no disconnection, and therefore there is no lead portion (2) and there is no filament body. Not only in the case of (1) only, but also in the case of having the lead part (2)
(F) The whole can be flushed, and the flushing work becomes very simple. In particular, in the case of only the filament main body (1) having no lead part (2), the work for the lead part (2) can be omitted, and the effect of shortening the work is remarkable.

Without the lead portion (2), the filament body (1)
When welding the connection part (4) that is formed by spirally winding the power supply connector (3) directly to the end part of the mount, shorten the entire length of the mount (M) because there is no lead part (2). You can do it.
In addition, as described above, since the non-melted portion (10a) of the connection portion (4) overlaps the end portion of the filament body (1) or the lead portion (2), vibration is transmitted from the outside during use. Even if it comes, the overlapping portion which is the non-melting portion (10a) absorbs this vibration, and the welding portion (10) is not directly vibrated, so that the vibration resistance of the connection portion (4) is greatly improved.

In claim 3, "the connecting portion (4a) has a larger diameter than the main body portion (3a) of the power supply connector (3)".
Characteristic, especially in this case the filament
When the inner diameter of the connection part on the (F) side is large, the power supply connector
Since it is not necessary to thicken only the connecting portion (4a) which is the insertion end of (3) and thicken the main body portion (3a) of the power feeding connector (3), it is effective for weight reduction. In particular, it is effective for the mount (M) for copying machines. (See Figures 12 and 13)

"Claim 4" is characterized in that "the filament protrusion (5) extends from the filament body (1) or the lead portion (2) or the power feeding connector (3)". According to this, the melting protrusion (5) is preferentially melted by arc discharge or laser light irradiation, and the melting member is rotated around the connection part to join with the same kind of metal, when directly melting the connection part. Unlike this, it is possible to prevent loosening of the connection part due to excessive melting.

[ Claim 5 ] is a book of the connector (3) for power feeding
Part of the body part (3a) is the filament body (1) or the lead.
It is bent so as to avoid the fused part (10) with the cord part (2).

(F) is attached to the filament body (1) that does not have the lead (2).
However, the same applies to the lead section (2).
In the case of the lead part (2), the number is shown in parentheses.
It was Also, the power supply connector (3) has only the connection part (4),
When the positioning protrusion (7) is formed integrally
Therefore, the positioning protrusion (7) is indicated by an imaginary line.

No lead part (2) is provided as in the first embodiment.
Use only the main filament body (1) and supply power to both ends.
When the connector (3) for welding is fused, the length of the lead (2) is almost the same.
Since the minutes can be omitted, the mount (M) itself
Can be shortened, and in the case of Figs. 3 and 4,
Compared with incandescent using a mount (M) without lead (2)
The total length (S1) of the light bulb can be shortened as shown in Figs. 8,
The same applies to the case of 9.

This welding-based connection method is used when connecting at the time of welding.
Since no force is applied to the part, a filament with a thin wire diameter
Particularly advantageous for connecting the main body (1) to the power supply connector (3)
At the same time, since no force is applied as described above,
Align the filament body (1) with the filament body (1)

The same applies to the case of
The connection part (4) of the connector (3) and fit a part of the joint part between them.
It will be welded. Regarding the partially welded structure of the connection part
It will be described in detail later.

Second Embodiment of Assembling Method of Mount (M)
Contrary to the above, Fig. 14 shows that the filament body (1)
Insert one end of the power supply connector (3) inside the end or inside the lead (2).
Insert the small diameter connection part (4) formed at the end,
Part of (4) is the end of the filament body (1) or the lead part
This is the case when it is welded to (2). In this case, connect the power
The connection part (4) of the switch (3) is in a coiled state.
It may be a simple solid rod or a line,
As will be described later in detail, the insertion part is melted and its surface tension

Different metals may be used. The sleeve (12) may be cylindrical in shape
And wrap a thin wire around the insertion end of the power supply connector (3).
A digit (not shown) may be used.

The power supply connector (3) will be described in the case where the connecting portion (4) has a larger diameter than the main body portion (3a) as shown in FIG. In the figure, the large-diameter connection portion is shown by (4a). The power supply connector (3) may be composed of a single rod or a wire, but the filament main body (1) with a large inner diameter or the lead portion (2) with a large inner diameter drawn from the filament main body (1) When the end portion is inserted inside and welded, the mount (M) has a significant effect in terms of weight reduction. An example thereof is shown in FIG. Particularly, in the case of the straight tube type incandescent light bulb used as the light source for the copying machine shown in FIG. 10, the weight of the mount (M) stretched inside the envelope (8b) can be reduced, and the disconnection and the filament (F) can be achieved. It has a remarkable effect in solving problems caused by the fact that the mount (M) has a large self-weight.

Next, when the welding of the connecting portion is a part,
It will be explained with reference to FIG. 13. Filament book as shown
The outer diameter of the body (1) or the lead part (2) is (D1)
Power supply connector that is fitted and partially welded
The inner diameter of the connection part (4) of (3) is (D2), and the non-welded part of both
The outer diameter is (10a)
