Cov neeg cog qoob loo hauv tsev paub qhov xyaum: koj nqis peev rau hauv lub teeb, tweak cov as-ham, saib xyuas temps, thiab tseem xav tias vim li cas cov txiaj ntsig tsis zoo sib xws rau cov nroj tsuag sab nraum zoov. Cov nroj tsuag loj hlob, paub meej, tab sis lawv feem ntau ncab ntau dhau, buds nyob hauv xoob, flavours xav tias tiaj tus, los yog nplooj qhia qhov kev ntxhov siab uas yuav tsum tsis txhob muaj. Qhov teeb meem feem ntau rov qab mus rau ib yam - lub teeb spectrum tsis yog "tag nrho" raws li daim ntawv thov.
Standard full-spectrum LEDs ua ib txoj hauj lwm zoo ua raws li lub hnub ci lub ntsej muag dawb. Lawv npog qhov yooj yim spectrum xav tau rau photosynthesis, txhawb cov cag thiab nplooj loj hlob los ntawm kev sib xyaw xiav lub teeb thiab txhawb kev paj thiab fruiting los ntawm kev sib xyaw xim liab. Tab sis khawb rau hauv qhov tiag - ntiaj teb kev ua tau zoo, thiab qhov khoob tshwm sim. Ntau tus neeg vam khom ntau rau ntawm phosphor- hloov pauv dawb COB lossis SMD array uas nce siab hauv 400–700nm PAR ntau yam. Thaum yooj yim thiab raug nqi- ua tau zoo, cov teeb no nquag nyob rau hauv - xa hauv ob thaj chaw tseem ceeb: tob liab nyob ib puag ncig 660nm thiab ultraviolet ze 395nm.
Cia peb pib nrog tob liab ntawm 660nm. Qhov no wavelength zaum nyob rau ntawm lub ncov haum rau chlorophyll ib (nyob ib ncig ntawm 662–665nm, raws li ntsuas nyob rau hauv ntau yam kuab tshuaj thiab nplooj kev tshawb fawb). Classic McCree nkhaus los ntawm 1972- tseem yog tus qauv ntsuas tom qab 50+ xyoo- qhia cov duab liab (600–700nm) tsav photosynthesis zoo, feem ntau txuam lossis dhau xiav hauv quantum yield ib absorbed photon. Kev hloov tshiab tsis ntev los no (xws li kev ua haujlwm ntawm txiv lws suav thiab lettuce) paub meej tias qhov siab tshaj nyob ze 660nm, txawm tias quantum yields tuaj yeem poob me ntsis ntawm qhov tseeb 660 vim yog cov ntsiab lus nqus. Hauv kev xyaum, siab -purity 660nm lub teeb hits chlorophyll qhov chaw qab zib, boosting zog hloov dua siab tshiab thaum lub sij hawm flowering thiab fruiting. Yog tias tsis muaj cov khoom muaj zog ntawm no, cov nroj tsuag hloov lub zog tsis muaj zog-stems elongate ("leggy" kev loj hlob), paj qeeb, thiab biomass tsub zuj zuj. Kev tshawb fawb ntawm cov qoob loo zoo li cannabis qhia tau hais tias kev sib cais liab zog ntawm ~ 640nm thiab 660nm tuaj yeem txhim kho cov teeb meem qhuav qhuav thiab siv lub teeb pom kev zoo piv rau ib qho nqaim 660nm ncov, tshwj xeeb tshaj yog nyob rau ntau dua.
Tam sim no cia peb tham txog UVA ib ncig ntawm 395nm. Lub hnub ci ntuj da dej cov nroj tsuag hauv qis- theem UVA txhua hnub, ua rau muaj kev tiv thaiv cov lus teb. Thaum nthuav tawm, cov nroj tsuag nce ntxiv flavonoids, anthocyanins, thiab lwm yam phenolic compounds -cov no ua cov tshuaj tiv thaiv ntuj, antioxidants, thiab kev ntxhov siab buffers. Kev tshawb fawb ntawm lettuce, buckwheat, thiab ntau yam txiv hmab txiv ntoo qhia tau hais tias UVA supplementation nce anthocyanin los ntawm 17-50%, ascorbic acid los ntawm 47-80%, thiab tag nrho cov metabolites theem nrab uas txhim kho xim, aroma, tsw, thiab kab mob kuj. Piv txwv li, UVA pab tsim cov phab ntsa tuab ntawm tes, txhawb nqa terpenes hauv tshuaj ntsuab, thiab txhim kho tom qab{11}} sau qoob zoo hauv txiv lws suav lossis berries. Feem ntau cov qauv tag nrho -spectrum COB LEDs tawm me ntsis kom tsis muaj UVA vim UV diodes kim, degrade sai dua, thiab tsis suav rau PAR / PPF metrics. Qhov tshwm sim? Cov nroj tsuag tsis tau txais cov "kev ntxhov siab{15}} ntxias" kev txhawb nqa zoo- xim nyob twj ywm, cov roj yam tseem ceeb tsis muaj zog, thiab kev tiv thaiv qis dua tiv thaiv kab tsuag lossis ib puag ncig kev sib hloov.
Cov kev txwv no piav qhia vim li cas ntau cov nroj tsuag sab hauv tsev muaj kev loj hlob tsis tu ncua. Txawm hais tias lub teeb pom tau tias yog tag nrho cov spectrum, nws tsis muaj qhov siv ntawm cov hlua tshwj xeeb uas yuav tsum muaj rau cov nroj tsuag kom hloov mus rau lub hnub ci tiag tiag.
Hybrid le caag hloov qhov ntawd. Los ntawm kev sib txuas ua ke ib qho txuas ntxiv mus ntxiv -spectrum COB core (xa txawm tias kev pab cuam hla pom wavelengths 380-800nm nrog flip-chip ntim rau qis thermal tsis kam thiab kev ntseeg siab) nrog lub hom phiaj SMD ntxiv, koj sau qhov khoob uas tsis muaj qhov nyuaj. Lub COB tuav lub hauv paus zoo li cov khoom siv hluav taws xob thiab cov hluav taws xob zoo tshaj plaws (tsis muaj cov hlau kub txhais tau tias qis thermal kuj thiab cov ntsiab lus tsis ua hauj lwm), thaum SMD 660nm reds ntxiv concentrated sib sib zog nqus-liab punch rau lub ncov photosynthetic tsav, thiab SMD UV-395nm muab qhov ploj lawm UVA trigger rau metabolite ntau lawm.
Qhov sib npaug, lub hom phiaj sau ua kom tiav ntau dua 380–800nm profile uas txhawb txhua theem - muaj zog veg los ntawm dav xiav -ntsuab, tawg tawg los ntawm tob liab, thiab kev txhim kho zoo los ntawm UVA - feem ntau nyob rau hauv ib qho yooj yim - rau - sib xyaw COB + SMD mix module.
Ntawm WELCOB, peb tau tsim cov kev daws teeb meem zoo li no nrog HP7440-220-50W-660+UV COB LED module. Nws siv flip-chip COB rau qhov ruaj khov 3500K COB puag (zoo heev dissipation ntawm 2.0W txhuas substrate), ntxiv rau SMD3030 660nm rau high-brightness sib sib zog nqus liab thiab UV-395nm emitters los puag ncig lub hnub zoo li tag nrho spectrum. AC 220-240V ncaj qha tsav (tsis muaj kev tsav tsheb ntxiv LED xav tau), cov terminals tsis siv rau kev teeb tsa sai, kev tiv thaiv ua ke (overvoltage, overcurrent, 4KV surge), thiab compact 40x74mm board ua rau nws siv tau rau LED loj hlob teeb, tsev cog khoom, ntsug ua liaj ua teb, thoob dej yug ntses, los yog DIY tej yaam num.
Yog hais tias koj lub teeb tam sim no tawm tawm los, tsw, lossis cog kev noj qab haus huv ntawm lub rooj vim qhov sib txawv ntawm qhov sib txawv, qhov kev tsim hybrid txuas rau lawv zoo. Xav paub seb nws yuav haum koj qhov teeb tsa li cas? Lub taub hau mus rau WELCOB lub vev xaib kom paub meej tag nrho, lossis poob ib daim ntawv yog tias koj tab tom sim nrog tweaks zoo sib xws.
