What Are The Types Of Ultraviolet Disinfection Lamps?
Sep 01, 2021
The ultraviolet disinfection lamps used in our country are:
(1) Ordinary straight tube hot cathode low pressure mercury ultraviolet disinfection lamp. The lamp tube is made of quartz glass or other glass with high ultraviolet transmittance, and the power is 40W, 30W, 20W, 15W, etc. The intensity of 253.7nm ultraviolet radiation (measured at a distance of 1m, without reflector) from the factory’s new lamp is: power>30W lamp, intensity ≥90Wcm2, (in the hospital infection management regulations promulgated in 2000, it is ≥100W/cm2), Lamps with power> 20W, intensity ≥ 60μW/cm2; lamps with power 15W, intensity ≥ 20W/cm2; because this lamp radiates 253.7nm ultraviolet rays while also radiating part of 184.9nm ultraviolet rays, it can produce ozone.
(2) High-intensity ultraviolet disinfection lamp. The intensity of 253.7nm ultraviolet radiation (measured at the center of the lamp tube at a vertical distance of 1m) is required for a power of 30W lamp, >170μW/cm2; 11W lamp, >40μW/cm2.
3) Low-ozone ultraviolet disinfection lamp. It is also a hot cathode low-pressure mercury lamp, which can be true tube type or H type. Due to the special process and tube material, the ozone output is very low, and the ozone output is required to be <1mg/h.
(4) Ultraviolet air sterilizer. It is made of low-ozone ultraviolet germicidal lamp, which can be used for indoor air disinfection under human conditions.
(5) Ultraviolet surface sterilizer. It is made of low-ozone high-intensity ultraviolet germicidal lamp, so that it can quickly become a satisfactory disinfection effect.
(6) Ultraviolet disinfection box. It uses high-ozone high-intensity ultraviolet sterilization or straight tube high-ozone ultraviolet production. On the one hand, it uses the synergistic sterilization effect of ultraviolet and ozone, and on the other hand, it uses ozone to sterilize the parts that cannot be irradiated by ultraviolet rays.
