Here's how it works:
1. Electric current: The lamp contains a gas, usually a mixture of argon and mercury vapor. An electric current is passed through the gas.
2. Excitation: The current excites the mercury atoms, causing them to emit ultraviolet (UV) light.
3. Phosphor coating: The inside of the lamp is coated with a phosphor material. The UV light from the mercury atoms strikes the phosphor, causing it to fluoresce and emit visible light.
Other devices that use similar principles include:
* Neon lamps: These use neon gas, which emits a characteristic reddish-orange light when energized.
* Sodium vapor lamps: These use sodium vapor, which emits a bright yellow light.
* Plasma displays: These use a thin layer of ionized gas (plasma) to create images.
