Nyali zokulirapo zofiira/zabuluu nthawi zambiri zimatchedwa kuti narrow-band spectroscopy chifukwa zimatulutsa mafunde mkati mwa kagulu kakang'ono ka bandi.
Nyali za LED zomwe zimatha kutulutsa kuwala "zoyera" nthawi zambiri zimatchedwa "broad spectrum" kapena "full spectrum" chifukwa zimakhala ndi mawonekedwe amtundu wonse, omwe amafanana kwambiri ndi dzuwa losonyeza kuwala "zoyera", koma kwenikweni pali palibe White light wavelength weniweni.
Tiyenera kudziwa kuti ma LED onse "oyera" ndi kuwala kwa buluu chifukwa amakutidwa ndi phosphor yomwe imasintha kuwala kwa buluu kukhala mafunde ataliatali.Phosphor imatenga kuwala kwa buluu ndikutulutsanso zina kapena zambiri mwa kuwala kobiriwira ndi kofiira.Komabe, kuphimba uku kumachepetsa mphamvu ya kutembenuka kwa photon kukhala kuwala kothandiza kwa photosynthetic (PAR), koma pakakhala gwero limodzi lowala, kumathandizira kuti pakhale malo abwino ogwirira ntchito ndikuzindikira mtundu wa spectral.
Mwachidule, kuti mudziwe mphamvu ya nyali, muyenera kugawanitsa photosynthetic photon flux (PPF) ndi madzi olowera, ndipo mphamvu yowonjezera mphamvu yomwe imapezeka imawonetsedwa ngati "μmol / J".Mtengo wokulirapo, nyaliyo imatembenuza mphamvu zamagetsi kukhala ma photon a PAR, momwe ntchitoyo ingakhalire yapamwamba.
1.Red / Blue LED Kukula Kuwala
Anthu ambiri nthawi zambiri amagwirizanitsa magetsi a "purple/pinki" akukula ndi kuyatsa kwa dimba.Amagwiritsa ntchito mitundu yosiyanasiyana ya ma LED ofiira ndi a buluu, ndipo amalimbikitsidwa makamaka kwa alimi owonjezera kutentha omwe amatha kupeza kuwala kwa dzuwa.Popeza photosynthesis imafika pachimake pamafunde ofiira ndi a buluu, kuphatikiza kwa ma spectra sikuli kothandiza kwambiri pakukula kwa mbewu, komanso kumapangitsanso mphamvu zambiri.
Kuchokera pamalingaliro awa, ngati wolima angagwiritse ntchito kuwala kwa dzuwa, ndizomveka kuti agwiritse ntchito mphamvu zambiri mu kutalika kwa mafunde omwe amathandiza kwambiri ku photosynthesis, kuti apititse patsogolo kupulumutsa mphamvu.Magetsi ofiira / abuluu a LED ali ndi mphamvu zowonjezera mphamvu kuposa "zoyera" kapena ma LED amtundu uliwonse, chifukwa LED yofiira / yabuluu imakhala ndi photon yapamwamba kwambiri poyerekeza ndi mitundu ina;ndiko kuti, amatha kutembenuza mphamvu zamagetsi kwambiri mu photons, kotero mtengo Kwa dola iliyonse, zomera zimatha kukula kwambiri.
2.Broad-spectrum "white light" kuwala kwa LED kukula
Mu wowonjezera kutentha, kuwala kwa dzuwa kumachotsa kuwala kwa "pinki kapena kofiirira" komwe kumapangidwa ndi nyali zofiira / zabuluu za LED.Pamene LED yofiira / yabuluu imagwiritsidwa ntchito ngati gwero limodzi lowala m'nyumba, mawonekedwe omwe amapereka kwa zomera ndi ochepa kwambiri.Kuphatikiza apo, kugwira ntchito mowunikiraku kungakhale kovutirapo.Zotsatira zake, alimi ambiri a m'nyumba asintha kuchoka ku ma LED ang'onoang'ono kupita ku "zoyera" zowunikira zonse za LED.
Chifukwa cha mphamvu ndi kutayika kwa kuwala pakusintha, mphamvu zogwiritsira ntchito ma LED amtundu wambiri ndizochepa kusiyana ndi ma LED ofiira / abuluu.Komabe, ngati agwiritsidwa ntchito ngati gwero lokhalo lowala paulimi wamkati, nyali zokulirapo za LED ndizabwinoko kuposa zofiira zofiira / zabuluu za LED chifukwa zimatha kutulutsa mafunde osiyanasiyana pakukula kwa mbewu.
Nyali za kukula kwa LED ziyenera kupereka kuwala koyenera kwambiri pakukula kwa mbewu ndi zokolola, kulola kusinthasintha kwa mitundu ya mbewu ndi kakulidwe kakukula, ndikupanga malo abwino ogwirira ntchito.
