What gases are lamps?
Typically, such lamps use a noble gas (argon, neon, krypton, and xenon) or a mixture of these gases. Some include additional substances, like mercury, sodium, and metal halides, which are vaporized during startup to become part of the gas mixture.
Which gas is used in halogen lamp?
The early history of the halogen lamp parallels that of the incandescent. The usage of chlorine to prevent blackening of the lamp was patented in 1882. In 1959, General Electric patented a commercially viable halogen lamp using iodine as the halogen gas.
Which gas is used in CFL?
In a CFL, an electric current is driven through a tube containing argon and a small amount of mercury vapor. This generates invisible ultraviolet light that excites a fluorescent coating (called phosphor) on the inside of the tube, which then emits visible light.
What gas is in a UV bulb?
UVC bulbs are filled with either Argon gas or a mixture of rare gases including Argon, Neon and/or other gases depending on the germicidal requirements for your application. They are constructed similarly to fluorescent lamps and operate the same with a similar discharge device.
What is natural gas heating?
