Marambi matsvuku/ebhuruu ekukura kwe LED anowanzo kunzi nhete-bhendi spectroscopy nekuti anoburitsa wavelengths mukati mediki nhete-bhendi renji.
Mwenje ye LED inokura inogona kuburitsa mwenje "chena" inowanzonzi "broad spectrum" kana "full spectrum" nekuti ine yakazara-band spectrum, yakafanana nezuva rinoratidza "chena" mwenje, asi chokwadi chiripo. hapana White light wavelength chaiyo.
Zvinofanira kutaurwa kuti ma LED ese "machena" mwenje webhuruu nekuti akaputirwa nefosphor inoshandura mwenje weblue kuita wavelengths refu.Phosphors inotora chiedza chebhuruu uye inobudisazve mamwe kana akawanda emafotoni muchiedza chegirini uye chitsvuku.Zvisinei, uku kupfekedza kunoderedza kushanda kwephoton kutendeuka kuva photosynthetic inoshanda mwaranzi (PAR) inogona kushandiswa chiedza, asi munyaya yechiedza chimwe chete, inobatsira kupa nzvimbo yekushanda iri nani uye kuona spectral quality.
Muchidimbu, kuti uzive kushanda kwemwenje, unofanirwa kupatsanura iyo photosynthetic photon flux (PPF) nekuisa mvura, uye kukosha kwesimba kunowanikwa kunoratidzwa se "μmol / J".Iyo yakakura kukosha, mwenje unoshandura simba remagetsi kuita PAR mafotoni, iyo yakanyanya kunaka ichave.
1.Mutsvuku / Bhuruu LED Kukura Chiedza
Vanhu vazhinji vanowanzo batanidza "yepepuru/pingi" LED inokura mwenje nemwenje webindu.Vanoshandisa misanganiswa yakasiyana yered uye blue LEDs, uye ivo vanonyanya kukurudzirwa kune varimi vegreenhouse vanogona kuwana chiedza chezuva.Sezvo photosynthesis ichikwira pane yakatsvuka uye yebhuruu wavelengths, musanganiswa uyu we spectra hausi iwo chete unonyanya kushanda pakukura kwechirimwa, asiwo yakanyanya simba-inoshanda.
Kubva pakuona uku, kana murimi achigona kushandisa chiedza chezuva, zvine musoro kuisa simba rakawanda muwavelength iyo inonyanya kubatsira kune photosynthesis, kuitira kuti iwedzere kuchengetedza simba.Mwenje dzvuku / bhuruu LED ine simba rakawanda kupfuura "white" kana yakazara-spectrum LED, nekuti tsvuku / bhuruu LED ine yakanyanya kunaka photon ichienzaniswa nemamwe mavara;ndiko kuti, vanogona kushandura simba rakawanda remagetsi mumafotoni, saka mari yemadhora ose, zvinomera zvinogona kukura zvakanyanya.
2.Broad-spectrum "white light" LED kukura chiedza
Mugreenhouse, chiedza chezuva chekunze chinodzima mwenje we "pink kana wepepuru" unoburitswa nemwenje tsvuku/yebhuruu ye LED.Kana iyo tsvuku / yebhuruu LED ichishandiswa sechiedza chimwe chete sosi mukati, iyo spectrum yainopa kune zvidyarwa ishoma.Mukuwedzera, kushanda muchiedza ichi kunogona kunge kusina kunaka.Nekuda kweizvozvo, varimi vazhinji vemukati vakachinja kubva kune nhete-spectrum LEDs kuenda ku "chena" yakazara-spectrum LED inokura mwenje.
Nekuda kwesimba uye kurasikirwa kwemaziso mukushandura maitiro, simba rekushanda kwe-broad-spectrum LEDs rakaderera pane iro rema LED matsvuku / ebhuruu.Zvisinei, kana ikashandiswa sechiedza chega chechiedza mukurima kwemukati, chiedza chekukura kwe LED chiri nani kudarika mwenje tsvuku / yebhuruu ye LED nokuti inogona kubudisa mazamu akasiyana-siyana pamatanho akasiyana ekukura kwezvirimwa.
Mwenje yekukura kwe LED inofanirwa kupa mwenje wemhando yakanyatsokodzera kukura kwechirimwa uye goho, uchiri kubvumira kuchinjika mumhando dzezvirimwa uye kutenderera kwekukura, uye kugadzira nharaunda yekushanda yakasununguka.
