It is used to replace oxygen so that the hot filament does not get oxidised or burn.
Because argon is an inert gas; the oxidation of the wolfram filament is not possible in pure argon.
If you use air instead of argon to fill a light bulb, the air will burn the light bulb.
it's not very reactive
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.

Argon is inert. This means that the filament in a light bulb can be heated to a high temperature in an environment where it will not react with the surrounding gases.
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. Double-glazed windows use argon to fill the space between the panes. The tyres of luxury cars can contain argon to protect the rubber and reduce road noise.
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.

When the filament of a bulb becomes hot, it can react with the air around it, causing it to change size and / or shape, breaking the filament. Argon is unreactive, and so when this gas surrounds the filament, it prevents it from reacting, so preserving it for a longer period.
