1. UV-C Quartz Lamp (58W with Ozone Function) This device uses a 58W UV-C spectrum lamp (wavelength: 253.5nm) to disinfect rooms and surfaces. 2. Wide - range Disinfection It is not only suitable for room disinfection but also for mattresses, bedding, and other places where viruses, bacteria, and mites may exist. 3. Ozone Function and Ventilation Requirement The lamp has an ozone function, which can disinfect areas in the room that UV light cannot reach. Therefore, the room must be ventilated after disinfection. 4. Remote Control and Timer The device is equipped with a remote control and a delay timer, allowing users to leave the room safely before the lamp turns on. 5. Usage Restrictions The device cannot be used when there are people, animals, or plants in the room. UV - C rays are harmful to eyesight and human skin. 6. Power and Disinfection Capacity It is calculated that the power of this device is sufficient to kill viruses and bacteria. For example, it can work effectively in a 60 - square - meter room. 7. Introduction to Ultraviolet Rays Ultraviolet rays are part of the electromagnetic spectrum, similar to X - rays, radio waves, or light. In practical use, ultraviolet rays are divided into three ranges: - UV - A: Long - wave range of 400 - 315 nm. UV - A rays come from the sun, activating photochemical and pigment - forming processes and having no relation to erythema - causing effects. - UV - B: Medium - wave range of 315 - 280 nm. UV - B rays are widely used in treatment, producing provitamin D and causing pigmentation and erythema effects. - UV - C: Short - wave range of 280 - 100 nm. UV - C rays have strong bactericidal and embryogenic effects, causing skin burns (erythema - causing effect) and conjunctivitis (conjunctivitis - causing effect). 8. Generation of UV - C Rays and Ozone in Lamps UV - C rays in germicidal lamps are generated when an electric arc passes through low - pressure mercury vapor (germicidal emitter). Ultraviolet rays with a wavelength of 200 nm can produce ozone in the air, which is a harmful phenomenon. To avoid this toxic effect, the germicidal bulbs in our lamps are covered with a special quartz glass cover. This cover has a high transmittance for germicidal radiation and can absorb unwanted ultraviolet rays with wavelengths below 200 nm. 9. Air Purification Process The air purification process uses internal and external emitters (for air and surfaces). It has been proven that ultraviolet rays with a wavelength of 250 to 270 nm have the maximum bactericidal effect. The bactericidal action of ultraviolet rays involves the absorption of ultraviolet rays by nucleic acids and proteins. The absorbed energy stimulates chemical reactions in the cell nucleus, thereby killing microorganisms. 10. Emission Characteristics of Our Lamps The bulbs used in our lamps emit the maximum germicidal energy only in the 250 - 270 nm range. - A: UV - C radiation in the 250 - 270 nm wavelength range can achieve the maximum bactericidal effect. - B: Nucleic acid absorption curve. - C: Cosmic radiation generated by low - pressure mercury leakage. 11. Applications Using germicidal lamps is one of the most efficient methods for air disinfection. These lamps emit UV - C rays with a wavelength range of approximately 253.7 nm. The radiation has a strong effect on killing bacteria, viruses, molds, fungi - causing bacteria, and various microorganisms. 12. Necessity of Germicidal Lamps To obtain a clean and sterile indoor environment, germicidal lamps must be used to achieve the guaranteed results. 13. Specific Application Scenarios UV - C rays are used in: - Operating rooms, consulting rooms, obstetric wards, quarantine rooms, dental clinics. - General clinics. - Laboratories. - Pharmacies. - Pharmaceutical, food, and cosmetic industries. - Hotel industry and culinary arts. - Kindergartens and schools. - Taxis and passenger transportation. 14. Usage Precautions The instructions for using the lamp must be carefully studied, and all requirements and methods for the daily use of germicidal lamps must be followed. 15. Selection of Lamp Quantity and Power The selection of the number and power of lamps in a room depends on many factors, such as room height, shape, maximum reflection coefficient of the surface (walls), temperature, humidity, and dust content in the room air.
