1. Glass Tube: This is the main body of the lamp, made of borosilicate glass, which allows for the passage of UV light and provides structural support.
2. Phosphor Coating: This layer on the inside of the glass tube converts the invisible ultraviolet (UV) radiation produced by the mercury vapor into visible light. Different phosphors produce different colors of light.
3. Mercury Vapor: This is the main source of light in the tube. When electricity is applied, the mercury vapor inside the tube emits UV light.
4. Electrodes: Located at both ends of the tube, these electrodes are made of tungsten filaments coated with an electron-emitting material. They initiate the electrical discharge in the mercury vapor.
5. Inert Gas: The tube is filled with an inert gas, usually argon or neon, which helps initiate the electrical discharge and assists in the vaporization of the mercury.
6. Ballast: This is an external component that provides the correct voltage and current for the fluorescent tube to operate efficiently. It also limits the current flow to prevent overheating and extends the life of the tube.
