Argon is often used when an inert atmosphere is needed. It is used in this way to protect the weld area and in incandescent light bulbs to stop oxygen from corroding the filament.

The filament lasts for a long time because argon is inert and will not oxidize the filament even at high temperatures.
If air were used, the oxygen would quickly react with and destroy the hot filament within seconds of it being turned on.
Quick experiment: Attach a wire to the positive and negative sides of a large flashlight battery (the large rectangular ones with the two coils coming from the top... I can't think of the proper size). Attach the back of one alligator clip to the open end of each wire (so the clip part is not clipped on the wire). String out some steel wool until you have a single strand (or two or three wound together). This essentially is a light bulb filament. Clip it into the two alligator clips and watch how fast it burns.

In a bulb a noble gas argon is used why is argon used instead of air in the light bulb?
Argon can be used in bulbs much like neon can; where neon gives
off a reddish-orange light, argon is a bluish tint. If argon is
used in an incandescent bulb it's probably to protect the filament
from oxygen in the air. However, I'm not sure this is ever actually
done; I know nitrogen is sometimes used for this purpose, but using
argon seems to be overkill.
Asked in Argon
Why is argon used instead on air in the light bulb?
The filament in the light bulb is heated to a very high
temperature. At such a temperature oxygen from the air would
oxidise the metal(s) in the filament and thereby destroy the bulb.
Using an inert gas such as argon in the bulb prevents such
oxidation.

Why air is not filled in electric bulb?
If air were used in an electric bulb the filament, which becomes
extremely hot when the light is on, would rapidly oxidize and burn
out in seconds.
Instead the bulb is filled with argon, which is inert.

Why is argon used in light bubs instead of vacuum?
argon is no reactive how ever vacuum
Asked in Chemistry
Can a light bulb work with just oxygen instead of argon?
No. Light bulb filaments become extremely hot when in use, and
oxygen, which is highly reactive, would cause the filament to burn
away in a matter of seconds.
Argon is used because it is inert, and thus will not react with
the filament.
Asked in Argon
Why was argon gas chosen for a light bulb?
Argon is often used when an inert atmosphere is needed. It is
used in this way in incandescent light bulbs to stop oxygen from
corroding the filament. Argon is used in fluorescent tubes and
low-energy light bulbs. A low-energy light bulb often contains
argon gas and mercury. When it is switched on an electric discharge
passes through the gas, generating UV light. The coating on the
inside surface of the bulb is activated by the UV light and it
glows brightly.
Asked in Science, Physics, Chemistry
Why is argon used insted of air in the light bulb?
because the oxygen in air would burn causing the light bulb to
burn out very quickly.
Asked in Light Bulbs and Artificial Lighting
Why are noble gases used in light bulbs?
Noble gases are used in light bulbs because of their properties.
For example, argon prevents tungsten filaments from evaporating.
Thus, argon increases the life of the light bulb.
Asked in Chemistry
Is there air in a light bulb?
No. Not normal air. The oxygen in air would cause any light bulb
to burn out in seconds. In stead, and inert gas called argon is
used.

various members of the element group known as halogens.
Asked in Argon
Why do they use argon gas in a light bulb?
It is used to replace oxygen so that the hot filament does not
