UVLED kev tiv thaiv ib puag ncig thiab txuag hluav taws xob yog qhov sib txawv loj hauv kev tsim cov teeb UV, yog li UVLED puas rau tib neeg lub cev?
Ua ntej, xam tawm qhov kev faib tawm ntawm cov duab hluav taws xob ultraviolet: UV-A (315-400 nanometers, tseem hu ua nthwv dej ultraviolet ntev), UV-B (280-315 nanometers, tseem hu ua nruab nrab nthwv dej ultraviolet), UV-C (100- 280 nanometers, kuj tseem hu ua luv-nthwv ultraviolet lub teeb; qhov thib ob, nws yog qhov pom tau tias lub teeb liab thiab lub teeb ci ultraviolet yog qhov sib txawv. Ob lub ntsiab lus. Ultraviolet feem ntau hais txog qis dua 400nm. Tau kawg, nws tseem hais txog 410nm hauv kev kawm. yog pom, ib yam li lub teeb dawb ib txwm, lub teeb liab, thiab lwm yam.
Tam sim no los teb cov lus nug saum toj no, puas yog UV LED puas rau tib neeg lub cev? Cov lus teb tsis yog, tab sis koj tsis tuaj yeem tua koj lub qhov muag ncaj qha. Nws yog kev lees paub. Tsis tsuas yog lub teeb liab, tab sis kuj lub teeb dawb thiab liab tsis tuaj yeem tua koj lub qhov muag ncaj qha. Puas yog UV teeb tsis zoo? Qhov no yuav tsum tau teb nyias. UV-B (280-315 nanometers, tseem hu ua nruab nrab-nthwv dej ultraviolet), UV-C (100-280 nanometers, tseem hu ua luv luv nthwv dej ultraviolet, yog qhov muaj teeb meem tiag tiag. Tshav ntuj muaj cov no. Yog li, thaum lub hnub muaj zog heev, nws yooj yim ua rau daim tawv nqaij puas tsuaj, yog li UV-B thiab UV-C yuav ua rau lub cev puas tsuaj thaum mus txog qee qhov, yog li yuav tsum tiv thaiv kev tiv thaiv zoo li UVA, nws tsis muaj teeb meem rau lub cev, tshwj xeeb yog Nrog rau kev siv dav dav ntau dua 360nm, tib neeg cov tawv nqaij muaj qhov ua haujlwm tiv thaiv, yog li nws tuaj yeem suav tias tsis muaj kev phom sij rau tib neeg lub cev. Tau kawg, nws yuav tsum tsis txhob cuam tshuam ncaj qha rau lub qhov muag.
Yog li ntawd, ntau thiab ntau tus neeg ntawm kev nkag siab tau siv UV LEDs los hloov cov tshuaj ib txwm muaj lub siab ua lub teeb rau cov kua nplaum, kho tus lej thiab lwm lub hom phiaj, thiab nws tau dhau los ua kev nthuav dav.
