Product Description
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.
Features of E-UV222 excimer light source
1. Green and environmental protection. There is no need to use mercury in manufacturing, no secondary pollution and waste recycling problems;
2. The monochromaticity is good, there is no stable ground state, and there is no self-absorption in the ground state. The power density of the lamp can be made large, the ultraviolet output energy is concentrated, and the local ultraviolet output
intensity is high;
3. There is no internal electrode inherent which is in the traditional light source, which avoids the contact between the
electrode and the plasma, the corrosion and sputtering of the electrode, and the service life is greatly extended;
4. It can be turned on and off instantly at any time, without preheating, the number of switches does not affect the service
life, and the number of switches is large;
5. Turning on and running are not affected by the ambient temperature, and the light output is relatively more stable;
6. Cold light source, no infrared output, no obvious heating effect on the processed object;
7. Compact size, can be larger according to the power of the adaptable power supply, and strong air cooling or water cooling is required for higher power;
8. The 222nm excimer ultraviolet lamp is preferably adapted to a pulsed power supply. Without any protective measures, the ozone output of the naked lamp is almost zero after the ignition point is stable;
9. Pay attention to ultraviolet rays hurting people, do not irradiate humans or animals!
222 nm wavelength excimer lamp application field
1. Inactivate viruses, bacteria, and microorganisms. Used for sterilization and disinfection in the fields of drinking water or sewage water treatment and air purification;
2. Photochemical reaction. Used to prepare electronic thin films and synthesize nanomaterials;
3. Surface modification of textiles. Used to increase the air permeability and moisture absorption of the fabric surface;
4. Photolyze hydrogen peroxide to produce strong oxidizing OH free radicals;
5. The cold UV printing light drying and curing in the printing process is especially suitable

How does UV light affect bacteria?
Microorganisms are simple organic structures that can easily absorb UV-C wavelengths, causing
photodissociation (destruction). Microbial DNA (deoxyribonucleic acid) is first adversely affected due to its weaker molecular
bonds. Within a hundredth of a second, it suffered irreparable damage. The subsequent loss of genetic instructions can cause the
cell to die and/or fail to replicate, making it harmless. Continuous exposure will cause uninterrupted degradation, such as the
sun, which will only be significantly faster.
Does UV-C lamp produce ozone?
No, but UVC does provide exceptional air conditioning, just like the sun is outdoors. The UVC fixture
is an air conditioning component in addition to other system components. These components include filters, coils, heating cores,
fans, dampers, humidifiers, etc. All of these components are designed to provide specific functions for treating the air in the
occupied space.
The disinfection principle of ultraviolet light?
There are many ways to demonstrate, sample or measure many things that happen. One is to use a contact plate containing malt agar. Before installing the UV-C, please lightly touch the surface with the board. Then it was incubated for approximately 96 hours. After installing UV-C, this step will be performed again at the same location. People often see a
reduction in growth of organisms by more than 98%? Different bacterial growth media can be used to similarly sample the water pan
and its water. Some other methods are:
o A significant reduction in mold can be seen in a short period of time.
o It has been shown that in less than 30 days, the coil pressure drop has dropped by more than 10% (depending on surface
cleanliness and water activity). Of course, system airflow and capacity usually increase accordingly.
o The drain pan and the water in the drain pan have become cleaner.
o All field wire surfaces, such as insulation materials, etc., will start to look cleaner.
o Most of the related odors produced by irradiated pollutants disappeared.
o Many indoor air quality complaints have been recorded as reductions.Application:
1.Used in various household appliances such as disinfection cabinets,microwave ovens,air conditioners,air purifiers,etc. 2.Disinfection and sterilization of air and surface of objects in hospitals,schools,hotels,restaurants,homes and offices.
