coj cog kev loj hlob teeb thiab zoo tib yam LED teeb sib txawv

1, lub wavelength ntawm lub luminous spectrum yog txawv:

Lub teeb pom kev loj hlob ntawm cov nroj tsuag feem ntau yog xim liab thiab xiav ntawm qhov pom lub teeb pom kev zoo, thiab lub teeb zoo tib yam tsuas yog lub teeb-emitting diode, thiab cov spectrum yog concentrated nyob rau hauv ntsuab.

LED siv nyob rau hauv thaj tsam ntawm cov nroj tsuag kab lis kev cai kuj qhia tau hais tias cov yam ntxwv nram qab no: hom wavelength yog nplua nuj, tsuas yog nyob rau hauv txoj kab nrog cov spectral ntau ntawm cov nroj tsuag lub teeb synthesis thiab lub teeb morphogenesis; Lub spectrum yoj dav yog ib nrab dav thiab nqaim, uas tuaj yeem ua ke kom tau txais lub teeb ntshiab monochromatic thiab sib xyaw spectrum raws li kev xav tau. tuaj yeem ua kom pom tseeb wavelengths ntawm lub teeb kom pom cov qoob loo sib npaug; Tsis tsuas yog yuav tswj lub flowering thiab fruiting ntawm cov qoob loo.

Nws tseem tuaj yeem tswj cov nroj tsuag qhov siab thiab cov ntsiab lus ntawm cov nroj tsuag; Lub kaw lus tsim hluav taws xob tsawg dua thiab siv qhov chaw tsawg dua, uas tuaj yeem siv rau ntau txheej kev cog qoob loo peb-seem sib xyaw ua ke, paub txog qhov tsis muaj cua sov thiab qhov chaw tsim khoom me me; Tsis tas li ntawd, nws qhov tshwj xeeb muaj zog durability kuj txo cov nqi khiav lag luam.

2. Sab nraud txawv

LED tseem hu ua lub teeb emitting diode, lub hauv paus tseem ceeb yog tsim los ntawm P-hom semiconductor thiab N-hom semiconductor nti, muaj kev hloov pauv ntawm P-hom semiconductor thiab N-hom semiconductor, hu ua PN hlws ris. Thaum cov tam sim no ntws los ntawm lub anode mus rau cathode ntawm LED, lub semiconductor siv lead ua emits txawv xim ntawm lub teeb los ntawm ntshav mus rau liab, thiab lub zog ntawm lub teeb muaj feem xyuam rau cov tam sim no.

Raws li kev siv luminous thiab kev ua haujlwm tam sim no tuaj yeem muab faib ua qhov ci ci zoo tib yam (luminous siv <10mcd), siab ci ntsa iab (luminous siv ntawm 10 ~ 100mcd) thiab ultra-high brightness (luminous siv> 100mcd) thiab lwm yam. Nws cov qauv feem ntau yog muab faib ua plaub ntu: cov qauv ntawm lub teeb faib hluav taws xob, cov qauv ntawm cov cua sov dissipation system, tsav Circuit Court thiab cov qauv siv tshuab / kev tiv thaiv.

Cov khoom siv hluav taws xob tsim hluav taws xob tsim hluav taws xob ntau dhau, xws li kev siv LED ntxiv teeb pom kev zoo thiab cov tshuab hydroponic, huab cua tuaj yeem siv dua, cov cua kub ntau dhau thiab dej tuaj yeem raug tshem tawm.

Cov hluav taws xob hluav taws xob tuaj yeem hloov pauv tau zoo rau hauv cov hluav taws xob photosynthetic thiab thaum kawg mus rau hauv cov teeb meem nroj tsuag. Cov kev tshawb fawb tau pom tias kev siv LED teeb pom kev zoo, lettuce loj hlob tus nqi, photosynthetic tus nqi yog nce los ntawm ntau tshaj 20%, LED siv nyob rau hauv cov nroj tsuag factories yog ua tau.

3. Kev siv sib txawv

LED teeb tuaj yeem hloov lub teeb kub kub los yog lub teeb txuag hluav taws xob, txij li 5-40 watts, lub teeb hluav taws xob qis qis, mus txog 60 watts (tsuas yog li 7 watts ntawm hluav taws xob).

LED cog teeb pab txo qis kev loj hlob ntawm cov nroj tsuag, vim hais tias lub teeb ci ntawm lub teeb no yog tsim los ntawm cov teeb liab thiab xiav, siv lub teeb pom kev zoo tshaj plaws ntawm cov nroj tsuag, liab wavelength siv 620-630nm thiab {{1 }}nm, xiav wavelength siv 450-460nm thiab 460-470nm.

Cov teeb pom kev zoo no yog tso cai rau cov nroj tsuag los tsim cov photosynthesis zoo tshaj plaws, cov nroj tsuag kom tau txais kev loj hlob zoo tshaj plaws hauv lub xeev, kev sim thiab cov kev siv tswv yim tau pom tias ntxiv rau muab cov nroj tsuag hauv qhov tsis muaj lub sijhawm teeb pom kev zoo, tab sis kuj txhawb kev sib txawv ntawm ntau lateral ceg thiab buds nyob rau hauv txoj kev loj hlob, accelerate qhov kev loj hlob ntawm cov hauv paus hniav thiab nplooj, accelerate lub synthesis ntawm cov nroj tsuag carbohydrates thiab vitamin synthesis, shorten lub voj voog loj hlob.
