Because argon is an inert gas; the oxidation of the wolfram filament is not possible in pure argon.
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.
For the filament tocatch fire you need to have oxygen present so depending on the type of light bulb it may be a vacuum inside or have some sort of inert gas inside that is not oxygen.
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.

Tungsten and an inert gas can be found inside of a light bulb.
3157 is the bulb type, the "K" means the bulb is filled with the inert gas Krypton.
Light bulbs are filled up by Neon or Argon gases, because they are inert.
