Which type of lighting is associated with the striking of phosphors by an electron beam?

Fluorescent lighting is associated with the striking of phosphors by an electron beam. In a fluorescent light, an electric current passes through a gas, typically mercury vapor, which produces ultraviolet light. This ultraviolet light then interacts with a phosphor coating on the inside of the bulb, causing it to glow and emit visible light. This process relies on the excitation of the phosphors, which is initiated by the energy from the light generated by the electron beam.

In contrast, incandescent lighting operates by heating a filament until it glows, while LED lighting utilizes semiconductor materials to emit light when electricity passes through them. Halogen lighting is a type of incandescent lighting where a halogen gas is used to increase efficiency and lifespan, but it does not involve phosphors or an electron beam. Thus, fluorescent lighting is distinct in its use of phosphors and the mechanism by which it generates visible light.
