Teeb
Yog li koj tab tom xav txog kev nqis peev hauv LED loj hlob teeb. Qhov ntawd yog xov xwm zoo - tab sis pom tseeb, thaum nws los txog rau kev tshawb pom yog tias koj tau xaiv txoj cai ntawm horticultural LED teeb pom kev zoo, qhov pov thawj yuav kawg nyob rau hauv paj npleg-i.e.cov lus teb cog lus pomtom qabkoj tau siv lub teeb loj hlob rau ob peb lub lis piam lossis ntau dua. Tab sis, los ntawm qhov ntawd, koj nyob nraum hom kev cog lus thiab ib nrab ntawm txoj kev taug! Yam dab tsi koj tuaj yeem saib rau hauv lub khw loj hlobua ntejkoj siv lub plunge thiab yuav ib qho LED rau cov nroj tsuag loj hlob hauv tsev?
Thaum koj tab tom yuav ib qho khoom siv LED, koj tab tom yuav ib hom "hloov tshuab hloov pauv": koj lub hom phiaj yog hloov hluav taws xob (hluav taws xob) rau hauv photons (lub teeb) - hauv lwm lo lus, thaum koj tab tom yuav LED loj hlob teeb koj yog "yuav lub teeb". (Los yog "photon yav tom ntej" yog tias koj nyiam ua si hauv kev lag luam!) Muaj ob yam tseem ceeb uas yuav tsum tau xav txog ntawm no rau koj lub peev xwm loj hlob lub teeb peev: qhov ntau ntawm lub teeb lub teeb yuav emit cuam tshuam rau nws lub zog noj thiab qhov zoo ntawm lub teeb. tsim tawm.
Nqi vs Output
Txhawm rau ua kom lub neej yooj yim dua thaum sib piv LED fixtures peb tau tsim lub laij lej online kom koj tuaj yeem sib piv tau yooj yim npaum li cas lub teeb koj tuaj yeem tsim nrog Hnub Teeb Teeb piv rau lwm qhov teeb pom kev zoo LED.
Peb tsim cov cuab yeej no los pab cov neeg cog qoob loo zoo li koj! Yog tias koj tab tom yuav lub teeb koj xav paub ntau npaum li cas koj yuav tau txais rau txhua £ koj siv rau koj lub teeb pom kev zoo.
Lub teeb zoo
Yog tias koj tab tom npaj siv koj lub teeb pom kev loj hlob LED ua lub teeb ci ib leeg (i.e.nyob rau hauv ib chav loj hlob nyob rau hauv tsev, es tsis yog ib tug ntxiv teeb nyob rau hauv lub tsev xog paj) ces qhov zoo ntawm lub teeb emission los ntawm koj loj hlob teeb yog ib tug loj deal! Tom qab tag nrho, koj lub teeb pom kev loj hlob yog lub luag haujlwm los tsim txhua qhov photon ntawm lub teeb uas koj cov nroj tsuag yuav tau txais thiab cov photons suav nrog lub zog nkag ntawm photosynthesis.
Tab sis tos - peb txhais li cas los ntawm "lub teeb zoo"? Ib photon puas tuaj yeem "zoo dua" lossis "zoo dua" dua li lwm tus? Zoo, thaum nws los txog rau qhov zoo ntawm lub teeb, peb yuav tsum tau rov qab me ntsis thiab saib tag nrho cov photons peb cov teeb loj hlob xa tuaj. Puas muaj ntau yam ntawm wavelengths / xim thiab lawv puas noj qab nyob zoo piv rau ib leeg. Tsis tas li ntawd, cov photons no tau muab faib li cas? Puas yog lawv tawg thiab diffuse lossis concentrated zoo li lub teeb / laser? Qhov tseem ceeb tshaj plaws rau cov neeg cog qoob loo, dab tsi cuam tshuam rau cov nroj tsuag kev loj hlob thiab kev loj hlob?
Saib rau lub hnub
Thaum nws los txog rau cov nroj tsuag thiab photosynthesis, nws ua rau kev nkag siab lees paub "tus qauv kub" ntawm cov nroj tsuag teeb pom kev zoo-Lub Hnub! Tom qab tag nrho, cov nroj tsuag tau hloov zuj zus rau ntau lab xyoo los siv lub hnub ci ntuj - yog li lub hnub ci cov yam ntxwv tseem ceeb yog dab tsi?
Lub hnub yog ib tug tag nrho spectrum, nruam teeb qhov chaw. Qhov no txhais tau hais tias nws muab tag nrho cov xim, los ntawm violet mus txog rau xim liab, txhua lub sijhawm, tsis muaj qhov ntse peaks lossis troughs. Cov nroj tsuag kuj tau txais ultraviolet thiab infrared hluav taws xob los ntawm lub hnub. Tsis tas li ntawd, yog tias koj xaiv hom nroj tsuag yog ib txwm nyob rau qhov siab dua, nws yuav tau hloov mus rau qib siab ntawm ultraviolet thiab infrared, vim tias atmospheric absorption qis dua koj mus.
Mono thiab Phosphor-Coated Diodes
Horticultural LEDs tuaj nyob rau hauv ob hom loj: mono thiab phosphor-coated. Mono diodes emit lub teeb nyob rau hauv ib tug xim - feem ntau nyob ib ncig ntawm lub wavelength ntawm ib ncig ntawm 15 nanometers. Phosphor-coated diodes emit tag nrho spectrum teeb, tab sis ntawm tus nqi poob ib co efficiency. Qee lub tuam txhab LED teeb pom kev hnyav hnyav ntawm cov diodes liab. Vim li cas? Zoo, liab yog ib qho ntawm cov xim tseem ceeb tshaj plaws ntawm lub teeb rau cov nroj tsuag thiab nws tau txais txiaj ntsig zoo los ntawm chlorophyl. Nws kuj tseem pheej yig los tsim cov LEDs liab thiab lawv muaj txiaj ntsig zoo, nrog qee qhov ntawm cov LEDs sab saum toj kawg nkaus ua haujlwm ntawm ntau dua 4 μmol / J! Yog li, chucking nyob rau hauv ib tug load ntawm liab diodes mus rau hauv lub mix thaum tsim ib tug LED horticultural teeb pom kev zoo fixture yog ib txoj hauv kev zoo los txhawb tag nrho cov kev ua tau zoo ntawm photon. Txawm li cas los xij, lub teeb liab ntau dhau tuaj yeem ua rau muaj kev pheej hmoo ntawm phototoxicity uas tuaj yeem ua rau bleached nplooj thiab paj, stunted generative txoj kev loj hlob, necrosis thiab pwm. Nws tseem tuaj yeem ua rau qee hom nroj tsuag kom siab thiab gangly thaum lub sij hawm vegetative theem, ua rau lawv tsis yooj yim rau kev txhawb nqa thiab teeb pom kev zoo thaum lub sij hawm flowering.
Raws li twb tau hais lawm, phosphor-coated "dawb" LEDs tsis zoo li cov diodes liab, tab sis lawv tsis ntev los no tau thawb los ntawm 3 μmol / J barrier. Lawv tsim ib tug zoo nkauj dav spectrum, npog txhua yam ntawm violet mus txog rau ntsuab, daj thiab liab. Muaj nyob rau hauv txawv "accents" (3K, 4K thiab 5K xim - 3K yog piav raws li "sov" los yog yellower dawb lub teeb whereas 5K yog "txias" nrog ib tug bluer tone), ib co manufacturers xaiv ib hom dawb diode thiab lwm tus neeg mus rau. ib mix.
Tag nrho Spectrum LEDs raug pom zoo rau kev siv sab hauv tsev
Rau kev siv sab hauv tsev, nrhiav tag nrho spectrum (aka broad spectrum) fixtures nrog ib qho xim dawb. Foliage yuav tsum tshwm sim ntuj thiab ntsuab ntau dua li ntshav. Liab "mono" diodes yog ib qho tseem ceeb rau kev txhawb nqa biomass nyob rau hauv lub paj theem tab sis feem ntau ntawm cov diodes yuav tsum yog 3K, 4K los yog 5K phosphor coated.
