Product Description

The biggest problem with light bulbs is the sublimation of the filament. Due to the slight difference in resistance on the tungsten wire, the temperature varies. In areas with higher resistance, the temperature rises higher and the tungsten wire sublimates faster, resulting in a cycle where the tungsten wire becomes thinner and the resistance further increases; Finally, it caused the tungsten wire to burn out. Later, it was discovered that replacing vacuum with inert gas could slow down the sublimation of tungsten wire. Today, most electric light bulbs are filled with nitrogen, argon, or krypton gas.
