Thaum nws los txog rau LED teeb pom kev zoo, muaj ntau hom muaj nyob hauv khw. Ob qhov nrov tshaj plaws yog LED ib txwm thiab tag nrho spectrum LED. Thaum ob hom LEDs tawm lub teeb, muaj qhov sib txawv tseem ceeb ntawm lawv uas ua rau lawv haum rau ntau lub hom phiaj.
Ib txwm LED, tseem hu ua standard LED, emits lub teeb uas ntog nyob rau hauv ib tug tshwj xeeb wavelength range. Cov kab no feem ntau nqaim thiab tsom rau xiav thiab liab lub teeb wavelengths, uas yog qhov zoo tshaj plaws rau photosynthesis. Cov teeb pom kev zoo LED feem ntau yog siv rau hauv cov nroj tsuag sab hauv tsev kom txhim kho cov nroj tsuag kev loj hlob thiab tawm los. Lawv kuj feem ntau siv los teeb pom kev hauv tsev thiab chaw ua haujlwm vim lawv lub zog ua haujlwm tau zoo thiab lub neej ntev.
Ntawm qhov tod tes, tag nrho spectrum LED muab ntau yam ntawm lub teeb wavelengths uas ua rau lub hnub ci ntuj. Thaum piv rau ib txwm LED, tag nrho spectrum LED emits wavelengths uas muaj xws li infrared thiab ultraviolet lub teeb, nrog rau xiav, ntsuab, thiab liab. Yog li ntawd, tag nrho cov spectrum LED teeb tuaj yeem siv rau ntau lub hom phiaj, suav nrog kev ua vaj tsev sab hauv, kev yees duab, thiab txawm tias kho hauv tsev kho mob.
Hauv kev ua vaj sab hauv tsev, tag nrho cov spectrum LED yog nyiam tshaj li ib txwm LED vim nws muab lub teeb pom kev zoo dua qub uas txhawb nqa cov nroj tsuag noj qab haus huv thiab tuaj yeem ua rau muaj txiaj ntsig zoo dua. Hauv kev yees duab, tag nrho spectrum LED teeb muab cov xim zoo dua thiab qhov tseeb, uas yog qhov tseem ceeb rau kev ntes cov ntsiab lus thiab nuances hauv cov duab. Hauv tsev kho mob, tag nrho spectrum LED teeb tuaj yeem siv rau kev kho lub teeb los kho qee yam mob lossis txhim kho cov neeg mob lub siab.
Lwm qhov sib txawv tseem ceeb ntawm ib txwm LED thiab tag nrho spectrum LED yog lawv cov nqi. Tag nrho cov spectrum LED teeb yog feem ntau kim dua li ib txwm LED teeb vim lawv qhov dav ntawm lub teeb wavelengths thiab cov khoom zoo dua.
Txhawm rau kom ua tiav, LED ib txwm tso tawm lub teeb nyob rau hauv ib qho tshwj xeeb wavelength ntau yam, thaum tag nrho spectrum LED muab ntau qhov dav ntawm lub teeb wavelengths uas ua rau lub hnub ci ntuj. Tag nrho spectrum LED muaj ntau yam kev siv, tab sis feem ntau kim dua li ib txwm LED. Thaum kawg, kev xaiv ntawm ob yuav nyob ntawm koj qhov kev xav tau tshwj xeeb thiab nyiaj txiag.
