Filler Gas In Fluorescence And Incandescent Light Bulbs

Why are light bulbs filled with argon gas.

Filler gas in fluorescence and incandescent light bulbs.

They are used to change the color. The filament is enclosed in a bulb to protect the filament from oxidation current is supplied to the filament by terminals or wires embedded in the glass. Most standard incandescent light bulbs are filled with inert argon plus enough nitrogen to suppress arcing between the lead in wires. Argon gas is used in fluorescent and incandescent light bulbs to stop the oxygen in the light bulbs from corroding the hot tungsten filament the use of argon in light bulbs prevents the evaporation of the tungsten filaments which results in increased light bulb life.

An incandescent light bulb incandescent lamp or incandescent light globe is an electric light with a wire filament heated until it glows. All the light bulbs in this category use krypton and or xenon as part or all of the gas fill. Yes there can be other gases in very small amounts. Around the world governments have passed measures to phase out incandescent light bulbs in favor of the more energy efficient cfls.

However this filament is trapped inside a smaller inner bulb filled with. The argon is to make sure there is no oxygen or regular atmosphere in the bulbs while the mercury is what provides the actual light. The gas inside fluorescent light bulbs is a mixture of argon and mercury vapor. Like an incandescent bulb halogen bulbs use a filament in this case one made of tungsten to produce light.

It s true that cfl bulbs do contain a small amount of mercury sealed within the glass tubing and it can be released as vapor after a breakage. After all they are much more energy efficient. Incandescent and fluorescent are two types of light bulbs which are used in day to day lives. Incandescent bulbs and fluorescent bulbs are used in a range of applications varying from home and office lighting to large scale factories.
