A Angle of 60° 3mW Deep UVC Ultraviolet LED for Sterilization can kill 99.99% escherichia coli on the surface within 10 seconds at a distance of 2 cm.if UVC LED is used in water tank, air purifier and humidifier, what is the corresponding relationship between light power, light Angle, sterilization distance and sterilization time?

The application of Best UVC Ultraviolet LED Lights for Sterilization has been a hot spot, and its sterilization effects has been improved, and water purification, air purification, humidifier type white electricity is also the main direction of UVC.

In the question, light power, light Angle, sterilization distance and sterilization time are mentioned. In the normal theory, the light is small, the light power is concentrated, the energy radiation distance of the lamp bead will be a little longer, and the sterilization time will not be short. However, the specific needs to consider how to place Multi-wavelength 365nm UV Chip for Sterilization, how many LEDs is how many mW lights, the sizes of water storage space, air outlet wind speed and other factors.

International authoritative medical journal reports, the radiation dose needed to kill 99% of E.coli is 6600 uj/cm2. Radiation dose Ψ = irradiance E * irradiation time t, irradiance E = coefficient K * optical power per exposed area d2, from those formulas and date we can figure out the quantity demanded by Mini UVC Ultraviolet LEDs for Sterilization.

What UVC really does is radiate energy, and the penetration distance of radiant energy also needs to be considered. For example, what is the effective exposure distance of 1mW Best 275nm UVC Ultraviolet Light Emitting Diodes for UV Flashlight? How much does water, mist, or dust affect the exposure distance? In addition, it has been reported in international literatures that the bactericidal effect is judged as 260nm>270≈280nm>254nm, which is based on DNA Absorption and DNA Damage, which means that the wavelength selection is also exquisite.
