The germicidal lamp is a lamp designed with a special ultraviolet light source, which is mainly used to kill bacteria, viruses, molds and other microorganisms in the air, water or on the surface of objects. The working principle of this lamp is to destroy the DNA or RNA structure of microorganisms by emitting ultraviolet rays of a specific wavelength, thereby making them lose their ability to reproduce and survive, achieving the effect of sterilization and disinfection. It is widely used in hospitals, laboratories, food processing, water treatment and other fields, and is one of the important equipment to ensure public health and food safety.
