- Iphazamisekile kwixesha elifutshane, ikamva linokulindelwa
Nangona kunjalo, ukusukela kwikota yesithathu ka-2021, iitshiphusi ze-LED ezibomvu zezityalo ziye zacinezelwa yimfuno yentengiso yeemoto kunye ne-infrared LEDs kwaye kuye kwakho ukunqongophala, ngakumbi kwiichips eziphezulu.Kwangaxeshanye, ii-ICs zomqhubi wamandla azisasebenzi, ukulibaziseka kweshedyuli yokuthumela kunye nokuqhekeka kweNyakatho Melika kubalimi be-cannabis bangaphakathi ngokungekho mthethweni kuye kwachaphazela ukusebenza kokuthunyelwa kwemveliso ye-terminal, okubangela ukuba abanye abavelisi bezibane ze-LED bacothise izicwangciso zabo zokuvelisa kunye nezinto eziphathekayo. iinzame zokugcina.
Ukukhanya kwemveli VS ukukhanya kwezityalo: iimfuno eziphezulu kunye nomda ophezulu
Ukukhanya kwezityalo ze-LED kwahluke kakhulu ekukhanyeni kwendabuko, ngokukodwa ngokwemiqathango yokusetyenziswa, ukusebenza, iteknoloji, njl. Oku kwenza ukuba ukukhanya kwezityalo ze-LED zibe nomgangatho ophezulu woshishino.
Iimveliso zokukhanyisa izityalo zibeka phambili iimfuno eziphezulu zenkqubo ye-R&D izakhono, amandla okusungula okuzimeleyo, umgangatho kunye namandla okulawula iindleko.Phakathi kwabo, umahluko phakathi kwe-teknoloji ye-R & D kunye nezinye iimveliso zokukhanyisa zilele kuyilo lweefomyula zokukhanya.Ngokumalunga neechips, ukukhanya kwezityalo Ingqwalasela ephambili yemveliso i-photosynthetic photon efficacy PPE/photosynthetic photon flux PPF, ngelixa ukukhanya ngokubanzi kugxininise kakhulu kwimiba efana ne-LM kunye nokukhanya okuluhlaza okwesibhakabhaka.
Ngeenjongo ezahlukeneyo, abathengi baneemfuno ezahlukeneyo zokusebenza kwetshiphu.Ukukhanya kwezityalo ze-LED kufuna iichips ezinokukhanya okuphezulu okuphezulu kunye nokuthembeka okuphezulu.Xa ulandela ukukhanya kokukhanya kwe-230lm / w, kuyimfuneko ukusebenzisa i-substrates elungiselelwe ngokukodwa, i-flip-chips, izibuko ezikhethekileyo kunye nobunye ubuchwepheshe;xa ulandela ukuthembeka okuphezulu, ukhetho lolawulo lwenkqubo kunye nezixhobo eziphambili zekrwada kucetywayo Iimfuno eziphezulu kakhulu.Kwicala lokupakisha, ubunzima obukhulu bokungena kwimarike yokukhanyisa isityalo se-LED ilele kuphuhliso kunye nokuveliswa kweseti yemveliso ephezulu, ekumgangatho ophezulu wemithombo yokukhanya yezityalo ze-LED okanye izibane, ezifuna ukusombulula ukudibanisa kunye nophuhliso lolawulo olukrelekrele. yendawo yokukhanya, ifotobiology yezityalo, kunye neteknoloji ye-semiconductor ye-LED.Ingxaki.
Umahluko phakathi kokukhanya kwezityalo kunye nokukhanya kwendabuko kukuba ukukhanya kwezityalo kuhambelana ngakumbi neempawu zokukhula kwezityalo.Kufuneka kuthathelwe ingqalelo kwimbono ye-bio-optics, kungekhona nje ukuhambelana neemfuno zezityalo ezahlukeneyo zePPE / PPFD, kodwa kunye nokudibanisa ukukhula kwezityalo kwizigaba ezahlukeneyo Ukulungelelanisa i-spectrum formula, Ukungena kwimarike yokukhanyisa isityalo kungekhona. ifuna kuphela oovimba bobugcisa bemithombo yokukhanya kunye neemodyuli, kodwa kufuneka iqonde imarike kunye neendlela zomgaqo-nkqubo.Ukongeza, kwimimandla eyahlukeneyo, iintlobo zezityalo ezahlukeneyo, kunye nezigaba ezahlukeneyo zokukhula kwesityalo esinye, kuyafuneka ukuba kusekwe eyona ndawo ifanelekileyo kwaye isebenzayo "ifomula yokukhanya" yedatha kunye neenkqubo ezihambelanayo, ngoko ke ukuncamathela phakathi komthengisi kunye nomfaki-sicelo nako. phezulu.
Ukukhanya kwezityalo kusekelwe kumandla aphezulu kunye neemveliso eziphezulu, ezifuna ukuba iinkampani ziqokelele ixesha elide kwi-teknoloji yokupakisha ye-LED.Kwangaxeshanye, abathengi baneemfuno eziphezulu zobomi bemveliso yokukhanyisa isityalo se-LED, kwaye iimveliso zidinga iminyaka emi-5-10 yoqinisekiso lomgangatho.Iimveliso zokukhanyisa ziyimveliso ekhethekileyo yokukhanyisa kwiziganeko zokukhanyisa izityalo.Ngokomzekelo, ngokwenjongo yesicelo sokukhanya kwezityalo, kuyimfuneko ukuyila i-spectrum enokubangela impendulo ethile yezityalo;ngokuhambelana nobuchule be-spectrum, kuyimfuneko ukusebenzisa i-spectrum ecebileyo kunye ne-adjustable ye-LED ukufezekisa kunye nokwandisa i-spectrum.Ngokombono wokupakisha, itekhnoloji yokupakisha egqwesileyo iyafuneka ukuze kufezekiswe ukukhanya okuphezulu kokukhanya kunye neemveliso ezinokuthembeka okuphezulu, kunye noyilo oluhle kakhulu lwe-optical luyafuneka ukukhulisa ukukhanya kunye nobukhulu.
Ngokubhekiselele kunikezelo lwamandla, kukho imiqobo emithathu kwintsimi ye-LED yokukhanyisa isityalo.
1.Umda wobuGcisa.Izibane zokukhanyisa izityalo ziphuhlisa kwicala lamandla aphezulu.Okwangoku, umbane kwimarike ufikelele kwi-1200W, kwaye unokunyuka kwakhona kwixesha elizayo.Oku kubangela umngeni omkhulu kuyilo lomqhubi wamandla aphezulu kunye nomthamo wemveliso yabavelisi abatsha.
2.Umda woyilo olukrelekrele.Izityalo zidinga ukukhanya okwahlukileyo kwizigaba ezahlukeneyo zokukhula, kwaye iimfuno zolawulo lokukhanya ziimfuno zolawulo olukrelekrele lwamandla.
3.Umda wemarike.Kuxelwe ukuba zombini umgangatho wemveliso kunye neshishini ngokwalo lijongene nengxaki yokuthembela kwabathengi kunye nokuqatshelwa.Ukuba akukho ndawo ifanelekileyo yokungena, umthengi akayi kungxamela ukwazisa umenzi omtsha njengomthengisi.
Umlinganiselo we-input-output uba yingqwalasela ye-terminal.
Ukuqatshelwa kunye nokwamkelwa kweteknoloji yokukhanyisa isityalo se-LED ngabalimi bokugqibela kuye kwafikelela kwinqanaba eliphezulu, kwaye ukuzimisela ukusebenzisa ukukhanya kwezityalo ze-LED kuya kuba namandla.Nangona kunjalo, utyalo-mali lokuqala ekukhanyeni kwezityalo ze-LED luphezulu, kwaye i-input-output ratio ibe ngumlimi we-terminal.Eyona nkxalabo.Kwimeko yesicelo sokukhanya kwezityalo, iindleko zombane zibalelwa kwelona nani liphezulu lenkcitho yabathengi.Ngoko ke, ubunzima bangoku bokunyusa bugxile kwindlela yokulinganisa ukuchasana phakathi kokunyuka kweendleko zexesha elifutshane kunye nokukhululwa kwenzuzo yexesha elide.
Njengoko ishishini lokukhanyisa lemveli lisondela ngokuthe ngcembe kwisilingi, ukukhanya kwezityalo ze-LED kuye kwaba yindawo entsha yophuhliso lweshishini.Okwangoku, ukukhanya kwezityalo ze-LED kusebuntwaneni, kodwa sikholelwa ukuba kuya kuchatshazelwa zizinto zangaphandle ezifana nokukhula kwabemi, umhlaba ongonelanga olimekayo, umhlaba ongalinganiyo, ukhuseleko lokutya, ukungcoliseka kwendalo, utshintsho lwemozulu, kunye nokukhula kunye neendleko. yetekhnoloji yokukhanyisa izityalo ze-LED.Iqhutywa zizinto zangaphakathi ezinjengokuncipha ngakumbi, ukukhanya kwezityalo ze-LED kuya kuchuma kwaye kuzise izinto ezinempilo nezikumgangatho ophezulu kubo bonke abantu.
