Ultraviolet Sterilization UVC Lamp For Bus System 222nm Quartz Tube
Starting May 11, the MTA will place UV lights inside subway cars and buses at two subway and bus stops. The 'ultraviolet rays' emitted by these lamps consist of shorter, higher-energy wavelengths of light that can be harmful to humans if exposed to direct sunlight.
UV light is particularly good at killing organic matter, including virus particles, but whether it can effectively kill the new coronavirus is still unknown. UV lamps and robots are commonly used to disinfect objects such as water, laboratory equipment, and spaces such as buses and airplanes. If it works well, they will expand to more trains and buses, MTA officials said.
"Regularly maintain the germicidal lamp, observe whether the filament of the germicidal lamp is damaged, and whether the lamp tube is cracked. If there is, stop using it and replace it with a new one.

E-UV working principle
Excimer (excited dimmer, abbreviated as excimer) UV light source has a variety of discharge forms, including high-pressure glow discharge, dielectric barrier discharge, high-frequency capacitor discharge, microwave discharge and hollow cathode discharge,
etc., all of which are effective To excite the excimer to emit light. Among them, the dielectric barrier discharge (DBD) is widely used in research and application due to its simple structure, economical and practical. An excimer is a diatomic molecule in an excited state, and there is no stable ground state. Under normal circumstances, the excimer's existence time is on the order of nanoseconds, and when it transitions back to a state of less energy through spontaneous radiation, it will radiate UV photons and
decompose into atoms at the same time. The study found that the 222nm ultraviolet radiation produced by the KrCl* excimer lamp has a much better killing effect on some bacteria or viruses with strong UV resistance and strong repairing ability than 254 nm.
