Light tube, or fluorescent lamp, lamp tube, fluorescent tube, fluorescent lamp, is a kind of lighting device, which belongs to a kind of arc lamp. It uses electricity to excite mercury vapor in argon or neon gas to form plasma and emit short-wave ultraviolet rays. After the ultraviolet rays are absorbed by the phosphor, the phosphor emits visible light to illuminate, and the way of emitting visible light is fluorescence.
The general fluorescent tube is made of glass, with sockets at both ends to connect the power supply and fix the position of the fluorescent tube.
Unlike light bulbs, fluorescent tubes must be equipped with a ballast, which, in conjunction with the starter, generates an instant high voltage that allows the gas to be ionized.
In order to replace traditional incandescent lamps, in recent years, an improved fluorescent bulb that combines lamp tubes, ballasts and starters together with incandescent lamp holders has been developed, called energy-saving lamps, "energy-saving lamps" or "energy-saving lamps" "Ball" can directly replace incandescent lamps without replacing the lamp base.
