The main features of LED lights


There is a filament at each end of the fluorescent lamp. The tube is filled with a small amount of argon and thin mercury vapor. The inner wall of the tube is coated with phosphor powder. When the gas between the two filaments conducts electricity, it emits ultraviolet light, which makes the phosphor powder soft. Visible light.


Fluorescent lamp working characteristics: A high voltage is required when the lamp starts to ignite, and only a small current is allowed to pass during normal illumination. At this time, the voltage across the lamp is lower than the power supply voltage.
