ABOUT US
The ultraviolet germicidal lamp is actually a low-pressure mercury lamp. Low pressure mercury lamp is the use of low mercury vapor pressure (<10-2Pa) to produce ultraviolet light, its luminescent spectrum is mainly two: one is 253.7nm wavelength; the other is 185nm wavelength, and these two are all invisible ultraviolet rays.
The ultraviolet ray tube does not need to be converted to visible light, the wavelength of 100-200nm can play a very good bactericidal effect, because the absorption spectrum of the light wave has a rule, the ultraviolet rays have the maximum absorption in th...+MORE
