LED teeb tau dhau los ua neeg nyiam vim lawv lub zog ua haujlwm thiab ua haujlwm ntev. Lawv siv nyob rau hauv tsev, chaw ua haujlwm, thiab txawm nyob rau hauv daim ntawv thov horticulture. Txawm li cas los xij, muaj qee qhov tsis meej pem txog hom teeb ci tawm los ntawm LEDs thiab lawv qhov cuam tshuam rau kev noj qab haus huv. Ib qho ntawm cov lus nug nquag nug yog seb lub teeb LED puas tawm UVA lossis UVB hluav taws xob.
UVA thiab UVB yog hom hluav taws xob ultraviolet. UVA muaj qhov ntev wavelength thiab cuam tshuam nrog kev laus ntawm daim tawv nqaij thiab lub hnub puas tsuaj. UVB muaj luv luv wavelength thiab yog lub luag hauj lwm rau sunburn thiab cancer ntawm daim tawv nqaij. Ob hom UV hluav taws xob tuaj yeem tsim kev puas tsuaj rau tib neeg kev noj qab haus huv.
Thaum nws los txog rau LED teeb, nws yog ib qho tseem ceeb kom paub qhov txawv ntawm UVA thiab UVB hluav taws xob. Feem ntau ntawm LED teeb tsis emit ib qho tseem ceeb ntawm ob hom hluav taws xob. Raws li lub illuminating Engineering Society of North America (IESNA), lub spectral fais fab faib ntawm cov dawb LEDs tsis suav nrog ib qho tseem ceeb emission nyob rau hauv lub UVA los yog UVB ntau yam. Qhov no txhais tau hais tias qhov kev pheej hmoo ntawm UV raug los ntawm LED teeb feem ntau tsawg heev.
Txawm li cas los xij, qee qhov tshwj xeeb LED teeb, xws li siv hauv horticulture lossis thoob dej yug ntses, tuaj yeem tawm UVA lossis UVB hluav taws xob. Nyob rau hauv cov ntaub ntawv no, cov chaw tsim tshuaj paus yuav tsum qhia kom meej lub wavelength ntau yam ntawm lub teeb thiab muab cov lus ceeb toom tsim nyog los xyuas kom meej tias kev siv zoo.
Nws tseem tsim nyog sau cia tias raug UV hluav taws xob los ntawm LEDs tsis yog qhov kev pheej hmoo nkaus xwb. Lub teeb xiav tawm los ntawm qee lub teeb LED tau txuas rau kev cuam tshuam kev pw tsaug zog thiab lwm yam teebmeem kev noj qab haus huv. Txawm hais tias tus nqi ntawm lub teeb xiav tawm los ntawm LEDs feem ntau qis dua li ntawm lwm qhov chaw, nws tseem ceeb heev uas yuav tau xav txog qhov teeb meem no thaum xaiv LED teeb.
Hauv cov ntsiab lus, feem ntau ntawm cov teeb pom kev zoo ntawm LED tsis tso cov hluav taws xob ntau ntawm UVA lossis UVB. Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum ua tib zoo soj ntsuam hom teeb pom kev zoo ntawm LED thiab ua raws li cov chaw tsim khoom pom zoo rau kev siv nyab xeeb. Thaum tsis ntseeg, nrhiav tswv yim los ntawm tus kws tshaj lij.
