Umthombo Wokukhanya kwe-LED Usetshenziswa Kakhulu Ekukhanyeni Kwezitshalo---Oak Led Stadium Light

Ngokuthuthuka okusheshayo kwezikhungo zezolimo, ukutadisha izitshalo, ukukhanya okwengeziwe, umthombo wokukhanya kwenkundla ye-LED enezinzuzo zawo eziyingqayizivele, isetshenziswa kabanzi ekukhanyeni kwezitshalo. Njengoba amapharamitha okukhanya ezindawo zokukhanya zokukhula kwesitshalo anezidingo ezithile, ngakho-ke kudingeka abe namasu okulinganisa afanele kanye nezinsimbi zokulinganisa ngokunembile amapharamitha okukhanya emvelo yokukhanya ahlangabezana nezidingo ezikhulayo zezitshalo ezifanele, ukuze ukhethe inkundla yezemidlalo efanele. umthombo wezibani, ukucacisa umthombo wenombolo nokuhlelwa komthombo wokukhanya ukuze kuhlinzekwe izisombululo ezifanele zokuthuthukisa izinhlelo zokusebenza ezisuselwe kuzidingo ezinengqondo zesitshalo ukuze kukhanye. imikhiqizo yokukhanya yezikhukhula ze-LED ekukhanyisweni kokutshalwa kwezitshalo, hhayi kuphela ukucabangela i-photometric eyisisekelo, ukusebenza kwe-radiometric, isidingo esisekelwe ezicini ze-photosynthesis zezitshalo, kucatshangelwa ukuminyana kwe-photon kwezitshalo nokutshala ubuso nobuso ekukhanyeni. wezinhlelo ze-quantum kanye nemingcele ye-photometric yesistimu ye-photometric yezitshalo ukuze kuhlolwe okuphelele kokusebenza kwemithombo yokukhanyisa yezitshalo. Ukukhanyisa kwesitshalo sesici esibalulekile kanye ne-1000w eholwa yizikhukhula ezidinga umkhiqizo wokukhanya kwekhwalithi yokuqala. Izitshalo ngokuvamile zithembele eqabungeni le-chlorophyll limunca imisebe yokukhanya, amabhande okumunca endaweni eluhlaza okwesibhakabhaka nokubomvu ngokuvamile, njengoba kukhonjisiwe ku-FIG. Ezitshalweni zimunca amandla okukhanya nge-photosynthesis ukuze ziguqulele ku-organic ukuze zikhule futhi zizalane. Ngakho-ke, isitshalo sokukhanyisa, kufanele siqale sicabangele amabhande okumunca we-irradiance, ngokuvamile angu-400nm ~ 500nm 600nm ~ 700nm irradiance amabhande aluhlaza kanye nombala obomvu, kanye nesidingo sokunquma ukwakheka okubukwayo okukhethiwe kokukhanya kwesitshalo, ububanzi, ukuphakama kwamaza nombala. izinga lokushisa. Okwesibili, ukukhanya komhubhe we-optical density.led Plant yamukela ukuminyana okuhlukile kokubona, kuzothinta ngqo ukukhula nokwakheka kwezitshalo. Njengalapho ukuminyana kwe-optical kuncipha, kuzoba khona ukuncishiswa kwezitshalo okufanayo, ukuhlukaniswa kwe-flower bud kubambezeleke ukuthuthukiswa kwesibeletho esibi nokunye. Ngoba, izitshalo kanye nezici zokuphendula zeso lomuntu zihlukile, inani leso lomuntu ekubonweni kokukhanya ngokuvamile lifinyelela uhlelo lokulinganisa ukukhanya, futhi i-photosynthesis yezitshalo ngokuvamile ibonwa ngokulinganisa kwe-quantum kanye nezinhlelo zokuhlola kanye nesistimu ye-photometric yezitshalo, imingcele yokuhlola i-photon. i-flux density (PPFD). UMc.Cree ngenani elikhulu locwaningo ubonise ukuthi phakathi kuka-400-700nm, ukuhlolwa kwe-gym light photosynthetic photon flux density kwenza amandla asebenza kahle akhazimulayo ahambisana nemiphumela yangempela yebhayoloji yemiphumela engcono yokukhanya. i-backpfrontp futhi, ukufana okukhanyayo. Njengoba ukukhanya kwe-LED kunokuqondisa okuqinile, futhi kungase kube nokufana kombala wokukhanya kwendawo, ngakho-ke, endabeni yokulima okukhulu kufanele uhlole ukufana kwe-irradiated surface irradiance ukuze uthole imvelo yokukhanyisa iyunifomu ephezulu. i-backpfrontp Ekugcineni, usuku olude. I-Spectrum yezitshalo ezahlukene idinga izidingo ezihlukene zezigaba ezahlukene zokukhula kwe-spectrum ihlukile, izikhungo zezolimo ekukhanyeni okufakelwayo kufanele zilandele ukukhanya kwezimpawu zomzimba zezitshalo, ukukhanya kugcwalise ukuze kuzuzwe imiphumela engcono kakhulu. Ngakho-ke, hhayi kuphela isidingo sokulinganisa okunembile kokubunjwa kwe-spectral yomthombo wokukhanya we-LED, kodwa futhi singaqaphela ushintsho ngokuhamba kwesikhathi ekukhanyeni. ukukhula kwesitshalo se-backpfrontp ngokulinganisa imikhiqizo yezibani zasemgwaqweni ze-LED backpfrontp ukukhanya kwesitshalo okujwayelekile, ngokuvamile kusetshenziswa imitha yokukhanya ukuze kulinganiswe i-quantum, kodwa ukufanisa empeleni kunzima ukufeza ukufana okuphelele kwe-spectral, ngisho nokungafani okunzima kakhulu, umthelela omkhulu ekunembeni kokulinganisa. Ngokuthuthuka kobuchwepheshe bokulinganisa okubukwayo, okusekelwe kumasu nemishini yokulinganisa i-spectroscopy iya ngokuya ivuthwa, futhi kancane kancane iyasebenza ekutholeni ukukhanya kwezitshalo.plant photosynthesis ehambisana nejika le-spectral lejika le-spectral elikhanyayo elikhanyayo lehlukile, ngakho-ke lapho kuhlolwa umphumela imithombo ehlukahlukene ye-irradiation, okufanele ihlolwe ngokuya ngejika lempendulo ye-spectral yomphumela wezitshalo ze-irradiation. Ukungafani kwe-spectroscopy akukona nje kuphela ukuthi azikho izinkinga, kodwa futhi kuyo yonke i-spectrum yekhwalithi yokukhanya, ukuminyana kokukhanya, ukusebenza okufanayo okukhanyayo kwazo zonke izici zemikhiqizo yokukhanyisa kwahlolwa. Kepha kunezinkinga zokukhanya ezimpofu nezilahlekile ezifana nezilinganiso ezijwayelekile ze-spectral, ngakolunye uhlangothi zikhawulela ukunemba kokulinganisa, kodwa futhi nemishini yokulinganisa eyenziwe izimfuno ezintsha. Isifinyezo sokuhlolwa kokusebenza kwe-backpfrontp yase-China Imboni yemikhiqizo yokukhanyisa ye-China ihlanganisa inqwaba yamasistimu okulinganisa, imingcele yokuhlola ngaphezulu, futhi i-spectrum yaso mincane, kungaba nge-hardware yokuhlola noma isofthiwe, inezidingo eziphakeme, ezifana nezitholi zemisebe yokubona ukunemba kwe-Spectral yokukala. Abakhiqizi bokukhanyisa izitshalo ze-backpfrontp kanye nezikhungo zocwaningo ezihlobene kufanele zisekelwe kwezazo noma izindinganiso, ukuze kube nomthelela wokukhanya ezitshalweni njengesisekelo, khetha izinhlelo ezifanele zokulinganisa, ukuhlola okuphelele nokunenhloso kokusebenza kweplanti yemikhiqizo yezibani ze-LED, kanye bese uklama ukukhanya kokukhula kwesitshalo Gcwalisa uhlelo noma uhlelo, wenze ukukhanyisa okuluhlaza, ukukhanyisa okuyonga amandla. isipele
