Yes there can be other gases in very small amounts.
Filler gas in fluorescence and incandescent light bulbs.
Most standard incandescent light bulbs are filled with inert argon plus enough nitrogen to suppress arcing between the lead in wires.
After all they are much more energy efficient.
The gas inside fluorescent light bulbs is a mixture of argon and mercury vapor.
They are used to change the color.
However this filament is trapped inside a smaller inner bulb filled with.
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.
Incandescent and fluorescent are two types of light bulbs which are used in day to day lives.
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.
When cfl bulbs were first introduced in the 1970s they were expected to spell the end of the traditional incandescent light bulb.
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.
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.
Around the world governments have passed measures to phase out incandescent light bulbs in favor of the more energy efficient cfls.
An incandescent light bulb incandescent lamp or incandescent light globe is an electric light with a wire filament heated until it glows.
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.
Incandescent bulbs and fluorescent bulbs are used in a range of applications varying from home and office lighting to large scale factories.
All the light bulbs in this category use krypton and or xenon as part or all of the gas fill.
Why are light bulbs filled with argon gas.
