Led wavelengths
NettetThe UV-C portion represents wavelengths from 200 nm – 280 nm, the wavelength used in our LED disinfection products. UV-C photons penetrate cells and damage the nucleic acid, rendering them incapable of reproduction, or microbiologically inactive. This process occurs in nature; the sun emits UV rays that perform this way. Nettet26. mai 2024 · Hi everyone and thanks for commenting - some great input here. I definitely get now that the LED suppliers are binning the LED wavelengths so that people can …

NettetThe LED emits ultraviolet light to infrared light with various wavelengths. This emission wavelength is expressed by the following equation using the energy band gap (Eg) of compound semiconductor material. λ (nm) = 1240/E g (eV) Larger Eg materials emit shorter wavelengths, and materials with smaller Eg emit longer wavelengths.
