Introduction.
It usually depends on the type of bulb Incandescent bulb use different principle of physics from LED which uses principals of Quantum Physics.
ANSWER.
Incandescent light bulb contains a thin wire (usually tungsten) called a filament that has a high electrical resistance. This filament gets very hot when an electric current passes through it. The intense temperature makes the filament glow brightly. If oxygen were present the glowing hot filament would burn up.
For combustion as we know it, oxygen must be present. In order to keep oxygen away from a light bulb’s filament on Earth, some bulbs have most of the air removed, others are simply filled with an inert gas (one that does not burn or aid combustion).
