Puas tuaj yeem sib sib zog nqus ultraviolet uvc coj nti ua tiav 254nm wavelength?
Sib sib zog nqus UV LEDs tuaj yeem ua tiav lub wavelength ntawm 254 nm. Raws li kev xav, lub teeb -emitting wavelength ntawm tob ultraviolet LED raws li AlGaN semiconductor cov ntaub ntawv system tuaj yeem qis li 203 nm (tam sim no, tus nqi qis tshaj qhia los ntawm cov chaw soj ntsuam thoob ntiaj teb yog 230 nm).
Sib sib zog nqus UV LED, UVC, Ultraviolet Germicidal Spectrum
Tab sis raws li pom nyob rau hauv daim duab 1, 254nm tsis yog ib tug zoo meej wavelength, thiab nws tsis yog tsim nyog rau LEDs mus cuag lub wavelength no.
So, why is the current LED mainstream not 265nm? Because, after the wavelength is adjusted to 265nm in Figure 1. DNA's ability to absorb ultraviolet rays of different wavelengths, the cost/selling price accompanying the decrease in production capacity and yield cannot support its sterilization performance better than 275nm. Therefore, after comprehensive consideration of cost performance, the mainstream UVC-LED wavelength is set at 275nm and an industry consensus has been formed.
Tab sis yog tias koj xav tau 254nm uvc smd leds, Guangmai technology muaj kev daws teeb meem hauv kev muab 255-260nm sib sib zog nqus uvc smd coj nrog 1W 10-15mw 3535 smd coj.
