。However, with conventional tube-shaped light bulbs, the filament with an anchor attached in advance is inserted into the cylindrical bulb, which makes assembly work difficult. Especially when the bulb is in the shape of a curved tube, the anchor gets in the way of inserting the filament. This is extremely difficult, and during the insertion process, the ring anchor often gets caught on the inner surface of the bulb, causing local stretching of the filament.
そこで、従来はリングアンカの直径を円管形バルブの内
径よりも小さくして挿入を容易にすることが考えられた
。Therefore, it has conventionally been considered to make the diameter of the ring anchor smaller than the inner diameter of the cylindrical valve to facilitate insertion.

を湾曲させる。Next, an example of a manufacturing method for processing the tube-shaped light bulb of FIG. 4 into a ring-shaped light bulb as shown in FIG. 1 and a method of fixing the ring anchor (5) will be explained. First, the end of the valve (1) is locally heated with a pair of burners, and when the valve is appropriately softened and the gas sealed inside the valve (1) is heated and balanced with the external pressure, The heated portion is curved with a predetermined curvature.
ついで、第５図に示すように、これに隣接したバルブ（

と同様な曲率で湾曲させる。Then, as shown in FIG. 5, the adjacent valve (
The burners (7) and (7) are moved to heat the part (11) of 1), and the other part (12), which has just been curved, is cooled by blowing cold air with the air cooling nozzle (8). Then, when the part (11) of the valve (1) is heated and softened appropriately, and the gas sealed inside the valve (1) is cooled and becomes balanced with the external pressure, the heated part (11) is heated as described above. Curve with similar curvature.
このようにして、バルブ（１）の全体を上述のように所
望の一部（１１）を加熱し、他の部分（１２）を冷却し
、封入ガス圧のバランスを取りながら順次湾曲させると
、第１図に示すように、環形赤外線電球が得られる。In this way, by heating the desired part (11) of the entire valve (1) as described above, cooling the other part (12), and sequentially bending the valve (1) while balancing the filled gas pressure, As shown in FIG. 1, an annular infrared bulb is obtained.

The valve (1) is compressed in the bending direction, in other words, in the annular radial direction, and is flattened to have an oval cross section, and the anchor (5
) is bitten into the softened glass in the minor axis direction and fixed.

（５）が移動も倒伏もしない。The ring-shaped infrared light bulb obtained in this way is bulb (1)
Since the ring anchor (5) is flattened, the ring anchor (5) is attached to the valve (1).
Despite having a smaller diameter than the inner diameter before bending, the shorter diameter of the valve (1) became smaller than the diameter of the ring anchor (5), and the ring anchor (5) dug into the inner surface of the valve (1). The valve solidified in this state. Therefore, the support of the ring anchor (5) is strong, and the ring anchor (5) does not move or collapse.

うこともなく。As described above, according to the manufacturing method of the fifth example, since the filament (4) with the anchor (5) attached is inserted when the bulb (1) is in the shape of a straight tube, the filament insertion operation is easy. Furthermore, since the lamp is bent after being filled with an inert gas, it is possible to mass-produce straight-tube sealed lamps and bend them into a desired shape to meet market needs. Furthermore, when making one bend, the cross section of the bulb (1) is solidified and made flat, and the anchor (5),
If (5)... is fixed, the anchor (5) will not move during use and the filament (4) will not expand or contract locally and the light distribution will not be distorted.

漬封゛止も容易である。Since the anchor (5) bites and is firmly fixed, the position of the filament (4) does not become eccentric due to collapse. Therefore, a slightly smaller anchor (5) can be used to further facilitate assembly. Further, the valve (1) can be easily sealed by pressure immersion.

移動や倒伏が防止できる。Although the above-mentioned embodiment describes a ring-shaped infrared light bulb used for heating a kotatsu or a stove, the present invention is not limited to this, and may also be a tube-shaped halogen light bulb used for decoration or OA equipment, or a bent shape made of soft glass. If applied to decorative light bulbs, it would be possible to mass-produce sealed straight tube bulbs and then bend them into the desired shape to meet the needs of the product, improving productivity and improving product quality. It is possible to satisfy diversification at the same time. In either case, by flattening the valve and fixing the ring anchor, it is possible to prevent the ring anchor from moving or falling down.

。In the above-mentioned embodiments, as a means for flattening the bulb, the balance between the internal and external pressures of the bulb and the softening temperature of the bulb were appropriately adjusted in the bending process, and the bulb was flattened when being bent. This is to simplify the process, and the present invention is not limited to this, and any known means may be used for flattening, and the flattening process is not limited to the above-mentioned example. It is sufficient if the ring anchor can be supported by

The shape of the valve is not limited to the above-mentioned example, but may be a straight pipe or another curved pipe shape. Furthermore, the present invention is not concerned with fill gas pressure.
