Izibani ze-LED zibizwa ngokuthi ukutshala kwangaphakathi "ilanga elincane", elingasiza izitshalo zikhule endaweni enokukhanya okuphansi.Ngakho-ke, kungani izibani ze-LED zingakhula zifinyelele lo mphumela?Lokhu futhi kuqala ngomphumela wokukhanya ezitshalweni.
Ukukhanya kungamandla, izitshalo zihlinzeka ngezinto namandla ekukhuleni kwazo kanye nentuthuko ngokusebenzisa i-photosynthesis, ethinta ukwakheka kwamandla okulinganisa, ukuvulwa kwe-stomatal, ukusebenza kwe-enzyme, njll ohlelweni lwe-photosynthesis.
Ngesikhathi esifanayo, ukukhanya njengesignali yangaphandle, kuthinta ukukhula nokuthuthukiswa kwezitshalo ezifana ne-geotropism ne-phototropism, i-gene expression, ukuhluma kwembewu, njll., ngakho-ke ukukhanya kubaluleke kakhulu ekukhuleni kwezitshalo.
Izitshalo ezigezwa ukukhanya kwelanga azinasithakazelo kuwo wonke ama-solar spectrum.Umthelela omkhulu ezitshalweni ukukhanya okubonakalayo okunobude beza obuphakathi kuka-400 ~ 700nm, futhi i-spectrum kulesi sifunda ngokuvamile ibizwa ngokuthi isifunda samandla esisebenzayo se-photosynthesis.
Phakathi kwazo, izitshalo zizwela kakhulu ku-red light spectrum kanye ne-blue light spectrum, futhi azizwela kakhulu ekukhanyeni okuluhlaza.I-spectroscopy yokukhanya ebomvu ingakhuthaza ukukhula kwe-rhizome yezitshalo, ikhuthaze ukwakheka kwe-carbohydrate, ikhuthaze uvithamini C wezithelo kanye nokwakheka kukashukela, kodwa ivimbele ukufana kwe-nitrogen.I-spectrum yokukhanya okuhlaza okwesibhakabhaka iyisengezo esidingekayo sekhwalithi yokukhanya okubomvu, futhi iyikhwalithi yokukhanya edingekayo ekukhuleni kwesitshalo, esiza ekuthuthukiseni ukuhlanganiswa kwe-oxide, okuhlanganisa ukulawula kwe-stomatal kanye nokunwetshwa kwesiqu ekukhanyeni kwesithombe.
Isekelwe ethonyeni lokukhanya ezitshalweni kanye "nokuthandwa" kwezitshalo ukukhanya, izibani ze-LED zikhula zisebenzisa izindlela zesayensi nezobuchwepheshe ukuze kuzuzwe ukukhanya okwenziwa esikhundleni sokukhanya kwelanga.Singakwazi ukuhlanganisa amafomula okukhanya ezitshalo ezahlukene ngokwezinhlobo zezitshalo ukuze sihlangabezane nezidingo zokukhanya zezigaba ezihlukene zokukhula kwezitshalo, ukuqhakaza, nokuthela izithelo.
