In a tubular incandescent light bulb, as shown in Fig. 5, a straight part is provided in a part of the large diameter part of the ring anchor that supports the filament, and a plate metal getter 12 is fixed to this part by folding it in half. (Akira Jitsuka
No. 61-169954), a tantalum plate 22 which also serves as a support for the filament 21 is installed in at least one place as shown in Figure 6 (Utility Model No. 57-72551).

However, powdered ones have the problem that they tend to fall off due to vibration or impact.Also, in halogen bulbs, if a metal getter is placed alone in the bulb, the halogen reacts with the getter, causing a halogen cycle. Since the required amount of halogen decreases, it may turn black, or the reaction product of halogen and getter may adhere to the inner wall of the bulb, causing it to turn white.

The present invention is a tubular incandescent light bulb in which a straight coil filament is placed inside a straight bulb and halogen gas and inert gas are filled.
A metal getter is placed on the straight portion of the lead wire to which the filament is attached, and a molybdenum sleeve is tightened and fixed to the lead wire so as to cover the metal getter.

As described above, according to the present invention, in a tubular incandescent light bulb in which a linear coil filament is disposed in a straight tube bulb and is filled with halogen gas and inert gas, the linear coil filament of the lead wire to which the filament is attached is A metal getter is placed on the lead wire, and a molybdenum sleeve is tightened and fixed to the lead wire so as to cover the metal getter.
There is no longer a direct reaction between the halogen gas and the metal getter, and the metal getter can be used as is in the halogen bulb. Further, when attaching the metal getter and molybdenum, since the lead wire is straight, the work can be easily performed.

になるからである。 Furthermore, even if the metal getter becomes brittle due to reaction with impure gas, there is no risk of it falling because it is surrounded by a molybdenum sleeve. Furthermore, after pinch sealing, the valve can be sufficiently degassed. This is because in order to degas the bulb, the entire bulb must be heated to a high temperature. Conventionally, this degassing process activates the getter, making it less effective in actual light bulbs, but molybdenum Because it is covered with a sleeve, the getter hardly reacts during short-time valve baking.
This is because it becomes a light bulb and exhibits a sufficient getter effect.
