Glass table lamps are also commonly known as LED fluorescent tubes, LED fluorescent tubes, LED fluorescent lamps, and their light sources use LEDs as luminaries. The traditional fluorescent tube is also known as fluorescent lamp, there is a filament at both ends of the lamp, the lamp is filled with a trace amount of argon and thin mercury vapor, the inner wall of the lamp is coated with phosphor, and the gas between the two filaments emits ultraviolet rays when conducting electricity, so that the phosphor emits visible light. Due to the heavy metal pollutant "mercury", the end-of-life fluorescent tubes are very polluting to the environment. The LED lamp uses a light-emitting diode as a light source, which has higher light efficiency, more energy saving, longer service life, and more environmental protection. It has become the most ideal product to replace fluorescent tubes at this stage.
