Ukukhanyisa kwe-Led Horticulture

Imikhiqizo yokukhanyisa izitshalo ibeka phambili izidingo eziphakeme zamakhono esistimu ye-R&D, amandla okuqamba azimele, ikhwalithi namandla okulawula izindleko.Phakathi kwazo, umehluko phakathi kobuchwepheshe be-R&D neminye imikhiqizo yokukhanyisa usekuklanyweni kwamafomula okukhanya.Mayelana nama-chips, ukukhanya kwezitshalo Okugxilwe kakhulu komkhiqizo ukusebenza kahle kwe-photosynthetic photon PPE/photosynthetic photon flux PPF, kuyilapho ukukhanya okuvamile kugxile ezindabeni ezifana ne-LM nokukhanya okuluhlaza okwesibhakabhaka.

Ngezinjongo ezahlukene, amakhasimende anezidingo ezahlukene zokusebenza kwe-chip.Ukukhanyisa kwesitshalo se-LED kudinga ama-chips anokukhanya okuphezulu okuphezulu nokusebenza kahle nokuthembeka okuphezulu.Lapho uphishekela ukusebenza kahle kokukhanya kwe-230lm/w, kuyadingeka ukusebenzisa ama-substrates alungiselelwe ngokukhethekile, ama-flip-chips, izibuko ezikhethekile nobunye ubuchwepheshe;lapho uphishekela ukwethembeka okuphezulu, ukukhethwa kokulawulwa kwenqubo kanye nezinto zokusetshenziswa ezibalulekile kuhlongozwa Izidingo eziphakeme kakhulu.Ngasohlangothini lokupakisha, ubunzima obukhulu bokungena emakethe yokukhanyisa isitshalo se-LED kusekuthuthukisweni nasekukhiqizweni kwesethi yemithombo yokukhanya yezitshalo ze-LED enesivuno esiphezulu, yekhwalithi ephezulu noma izibani, ezidinga ukuxazulula ukuhlanganiswa nokuthuthukiswa kokulawula okuhlakaniphile. yendawo ekhanyayo, i-photobiology yezitshalo, kanye nobuchwepheshe be-semiconductor ye-LED.Inkinga.

Umehluko phakathi kokukhanyisa kwezitshalo kanye nokukhanyisa kwendabuko ukuthi ukukhanya kwezitshalo kuhambisana kakhulu nezici zokukhula kwezitshalo.Idinga ukucatshangelwa ngokombono we-bio-optics, hhayi kuphela ukufanisa izidingo zezitshalo ezahlukene ze-PPE/PPFD, kodwa futhi nokuhlanganisa ukukhula kwezitshalo ngezigaba ezahlukene Ukulungisa ifomula ye-spectrum, Ukungena emakethe yokukhanyisa izitshalo hhayi idinga kuphela izinqolobane zobuchwepheshe zemithombo yokukhanya namamojula, kodwa futhi idinga ukuqonda imakethe namathrendi enqubomgomo.Ngaphezu kwalokho, ezifundeni ezihlukene, izinhlobo zezitshalo ezihlukene, nezigaba ezihlukene zokukhula zesitshalo esifanayo, kuyadingeka ukusungula isizindalwazi esifanelekile nesisebenza kahle kakhulu "sefomula yokukhanya" nezinhlelo ezihambisanayo, ngakho-ke ukunamathela phakathi komphakeli kanye nomfakisicelo nakho kufanele. ngaphezulu.

Ukukhanyisa kwezitshalo kusekelwe emikhiqizweni yamandla aphezulu kanye nokusebenza kahle, okudinga ukuthi izinkampani ziqongelele isikhathi eside kubuchwepheshe bokupakisha be-LED.Ngesikhathi esifanayo, amakhasimende anezidingo eziphakeme zokuphila kwemikhiqizo yokukhanyisa izitshalo ze-LED, futhi imikhiqizo idinga iminyaka engu-5-10 yokuqinisekiswa kwekhwalithi.Imikhiqizo yokukhanyisa iyimikhiqizo yokukhanyisa ekhethekile ngezikhathi zokukhanyisa izitshalo.Isibonelo, ngokusho kwesicelo sokukhanyisa izitshalo, kuyadingeka ukuklama i-spectrum engabangela impendulo ethile yezitshalo;ngokuya ngemininingwane ye-spectrum, kuyadingeka ukusebenzisa ukusebenza kwe-spectrum okucebile nokuguquguqukayo kwe-LED ukuze kuzuzwe Nokwandisa i-spectrum.Ngokombono wokupakisha, ubuchwepheshe bokupakisha obuhle kakhulu buyadingeka ukuze kuzuzwe ukukhanya okuphezulu kwe-quantum kanye nemikhiqizo enokwethenjelwa okuphezulu, futhi umklamo omuhle kakhulu we-optical uyadingeka ukuze ukwandise ukusatshalaliswa kokukhanya nokuqina.

Ngokuphathelene nokunikezwa kwamandla, kunemibundu emithathu emkhakheni we-LED plant lighting drive.
1.Umkhawulo wezobuchwepheshe.Abashayeli bezibani zezitshalo bathuthuka bebheke emandleni aphezulu.Njengamanje, ukunikezwa kwamandla emakethe sekufinyelele ku-1200W, futhi kungase kukhuphuke futhi esikhathini esizayo.Lokhu kubangela inselele enkulu ekwakhiweni komshayeli wamandla aphezulu namandla okukhiqiza abakhiqizi abasha.

2.Umkhawulo wokuklama ohlakaniphile.Izitshalo zidinga ukukhanya okuhlukile ezigabeni ezihlukene zokukhula, futhi izidingo zokulawula ukukhanya ziyizidingo zokulawula amandla ngobuhlakani.

3.Umkhawulo wemakethe.Kubikwa ukuthi kokubili ikhwalithi yomkhiqizo kanye nebhizinisi ngokwalo kubhekene nenkinga yokwethenjwa kwamakhasimende nokuqashelwa.Uma lingekho indawo yokungena efanelekile, ikhasimende ngeke ligijimele ukwethula umenzi omusha njengomphakeli.

Isilinganiso se-input-output siba ingqikithi yokunaka kwetheminali.
Ukuqashelwa nokwamukelwa kobuchwepheshe bokukhanyisa izitshalo ze-LED ngabalimi bokugcina sekufinyelele izinga eliphezulu, futhi ukuzimisela ukusebenzisa ukukhanya kwezitshalo ze-LED kuya kuba namandla.Kodwa-ke, ukutshalwa kwezimali kokuqala ekukhanyeni kwezitshalo ze-LED kuphezulu uma kuqhathaniswa, futhi isilinganiso se-input-output sesiphenduke umlimi wokugcina.Ukukhathazeka okuyinhloko.Esimweni sokusetshenziswa kokukhanyisa kwezitshalo, izikweletu zikagesi zenza ingxenye enkulu kakhulu yezindleko zamakhasimende.Ngakho-ke, ubunzima bamanje bokuphromotha bugxile endleleni yokulinganisa ukungqubuzana phakathi kokukhushulwa kwezindleko zesikhashana kanye nokukhululwa kwenzuzo yesikhathi eside.

Njengoba ibhizinisi lokukhanyisa lendabuko lisondela kancane kancane ophahleni, ukukhanya kwezitshalo ze-LED sekuphenduke indawo entsha yokuthuthukiswa kwebhizinisi.Njengamanje, ukukhanya kwezitshalo ze-LED kusanda kuqala, kodwa sikholelwa ukuthi kuzothintwa izinto zangaphandle ezifana nokukhula kwenani labantu, indawo enganele yokulima, umhlaba ongalingani, ukuphepha kokudla, ukungcoliswa kwemvelo, ukuguquka kwesimo sezulu, ukuvuthwa okuqhubekayo kanye nezindleko. yobuchwepheshe bokukhanyisa izitshalo ze-LED.Iqhutshwa izici zangaphakathi ezinjengokuncipha okuqhubekayo, ukukhanya kwezitshalo ze-LED kuzochuma futhi kulethe izinto ezinempilo nezisezingeni eliphezulu kuso sonke isintu.
