Gas Discharge Tube

A Gas Discharge Tube is a device made of a sealed container filled with a specific type of gas, like neon or argon. When an electrical voltage is applied, the gas becomes ionized, creating a visible glow or discharge. These tubes are used for lighting, displays, and as protective components in electronic circuits to suppress voltage spikes. They work by providing a controlled path for electrical energy, helping to prevent damage from sudden voltage surges. Essentially, they convert electrical energy into light or controlled conduction through ionized gas, serving both functional and aesthetic purposes in electronics and lighting.
