UV LED working conditions in indoor
Ultraviolet light strip for indoor air disinfection,often can not be reached on schedule sterilization effect because of irradiation intensity is not enough,   so we need to detect the radiation intensity of ultraviolet light,The UV led basic idea was this use of UVC radiation intensity ultraviolet germicidal wavelength to irradiate,  therefore detect radiation intensity UV led with UVC ultraviolet radiation meter (also called UV light meter, UV intensity meter, etc.).  UV radiation intensity is the basic factors for affecting the disinfecting effect, according to the “disinfection technical specifications” provisions. ordinary 30W UV lamp, the new UV lamp radiation intensity should be greater than 100VW / cm2 (distance 1m) is qualified, the radiation intensity of the lamp is used to reach the minimum 70VW/cm2 can be used, but must be increased irradiation time.
According to the formula of ultraviolet irradiation = ultraviolet radiation * irradiation time can be obtained to extend time for different intensity, it can also be obtain that low-intensity or high-intensity short time sterilization can get the same effect. If the intensity of the ultraviolet light source is less than 40VW / cm2, it can not be used to prolong the irradiation time. Do not think that as long as the UV lamp is lit,The UV led Will be able to job( sterilization).
