Introduction to fluorescent lamps

Fluorescent lamps are also known as fluorescent lamps. It looks fine and long. There is a filament at each end of the fluorescent lamp. The lamp tube is filled with a small amount of argon and thin mercury vapor. The inner wall of the lamp tube is coated with phosphor, and the gas between the two filaments emits ultraviolet rays when the gas is electrically conductive, so that the phosphor emits soft visible light.
