Why Do Light Bulbs Need A Vacuum at Deanna Clarke blog

Why Do Light Bulbs Need A Vacuum. We also suspect our bulb has a perfect vacuum seal that further protects its innards. The catch is, this filament also interacts with the air around it. If air particles are present inside the bulb, it will heat up quickly and the glass will break easily. The bulb is generally made of glass, within which is a vacuum. If enough oxygen is present inside the glass, the heat produced in the filament would. By the way, even without oxygen present a filament eventually. If the bulb had air inside of it the filament would quickly heat up and essentially burn up. Since the light’s novelty became apparent, we’ve discussed how to best protect it. However, a filament and electrical current alone are not sufficient to make a light bulb. Well, in a typical bulb, the thin wire filament heats up to produce light when electricity passes through it. And just to add, you need a vacuum inside the tube for the same reason as in a light bulb—if there were air inside, the filament would burn up. Why does the bulb contain a vacuum? An incandescent bulb mainly consists of two parts—the bulb and the filament. Since the vacuum of space would have no oxygen, a bare filament would work as a light bulb without the glass globe. To keep the tungsten filament from catching on fire at such a high temperature, light bulbs are made with all the oxygen sucked out to create a near vacuum.

Since the vacuum of space would have no oxygen, a bare filament would work as a light bulb without the glass globe. However, a filament and electrical current alone are not sufficient to make a light bulb. By the way, even without oxygen present a filament eventually. The vacuum helps in extending the life of the light bulb; If the bulb had air inside of it the filament would quickly heat up and essentially burn up.
