Intshayelelo: Ukutshixwa kweChen kunye nabanye abasuka kwiYunivesithi yasemazantsi kunye neTekhnoloji sele bephuhlise uthotho lwe-Dot Dot-Ect Liting Diode ekhupha i-Indin Zinc i-Inim ye-Indim's Binc i-Excode njengoMgaqo-nkqubo oPhakamileyo. I-Diode inokusebenza phantsi komjikelo oqinisekileyo nongalunganga wemijikelezo ekhoyo, enemisebenzi yangaphandle ye-20.09% ne-21.15%, ngokulandelelana. Ukongeza, ngokudibanisa izixhobo ezahlukeneyo ezixhunyiweyo, iphaneli inokuqhutywa ngokuthe ngqo ngamandla ee-AC zekhaya ngaphandle kwesidingo sesekethe esinzima seBhackend. Phantsi kwedrive ye-220 v / 50 h / 50 h / 50 hz, amandla enkqubo ebomvu iplagi yeplagi kunye nephaneli yokudlala i-15.70 lm W-2, kunye nobuqaqawuli obunotshintsho bungafikelela kwi-2583 CD M-2.
Ukukhuphela ukukhanya kwee-Dodwes (ii-LEDS) ziye zaba yiTekhnoloji yokukhanya ephambili ngenxa yokusebenza kwawo okuphakathi, ixesha elide lexesha, ilizwe kunye nokusingqongileyo kwezendalo, ukuhlangabezana nemeko yendalo yokusebenza kunye nokuzinza kwendalo. Njengomntu we-semiconductor pn diode, i-LED inokusebenza kuphela phantsi kwedrive ye-voltage ye-voltage ephantsi (DC). Ngenxa yenaliti engacacanga kunye nentlawulo eqhubekayo, iintlawulo kunye nokufudumeza kukaJoule kwisixhobo, ngaloo ndlela kuncitshiswa uzinzo lwe-LED. Ukongeza, ukubonelelwa kwamandla ehlabathi ngokubanzi kusekwe ikakhulu kwi-voltage ephezulu, kunye nezixhobo ezininzi zekhaya ezinje ngezibane ezikhokelayo azinakusebenzisa ngokuthe ngqo i-voltage ephezulu. Ke ngoko, xa i-LED iqhutywa ngombane wasekhaya, i-Ac-DC ye-AC-DC ye-AC-DC ifunwa njengomlimi ukuba iguqule amandla e-gonseli ye-oc ephezulu kwi-DC ye-DC. Umguquleli oqhelekileyo we-AC-DC ubandakanya i-transformer yokunciphisa i-voltage ye-mais kunye nesekethe yeresti yokulungisa igalelo le-AC (Jonga umfanekiso 1A). Nangona ukuguqulwa kokuguqulwa kwabaguquli be-AC-DC anokufikelela ngaphezulu kwe-90%, kusekho ilahleko yamandla ngexesha lenkqubo yokuguqula. Ukongeza, ukulungelelanisa ukuqaqamba kwe-LED, isekefiki yokuqhuba ngokuqhuba ngokuzinikela kufuneka isetyenziselwe ukulawula ukubonelela ngamandla i-DC kwaye ibonelele ngeyona ndlela ifanelekileyo ye-LED (Jonga umzobo wongezelelweyo 1B).
Ukuthenjwa kwesekethe yomqhubi kuya kuchaphazela ukuqina kwezibane ze-LED. Ke ngoko, ukubazisa abaguquli be-DC kunye nabaqhubi be-DC kuphela i-sucturs eyongezelelweyo (i-accounting malunga ne-17% ye-LIT ye-LIT), kodwa inyuse ukutya kwamandla kwizibane ezikhokelweyo. Ke ngoko, ukuphuhlisa izixhobo ze-LED okanye ze-elektrosument (EL) ezinokuthi ziqhutywa ngokuthe ngqo yikhaya le-110 v / 220 v ivolomente ye-50 HZ / 60 HZ ngaphandle kwesidingo sezixhobo ezinzima ze-elektroniki zinqweneleka kakhulu.
Kule minyaka ilishumi idlulileyo, i-AC ye-AC ye-AC eqhutywa i-ACRFAMPUMcection (i-AC-EC) ibonakalisiwe. I-Aclast eqhelekileyo ye-ACT iquka i-fluoresced powder ekrobekiswa ngesandwich ye-slownicted phakathi kweendawo ezimbini zokuthambisa (Umzobo 2A). Ukusetyenziswa kofakelo luthintela inaliti yeenqwelo zokudlela zangaphandle, ngenxa yoko akukho kukhala okuthe ngqo ngokusebenzisa isixhobo. Esi sixhobo sinomsebenzi we-capacitoti, kwaye phantsi kwedrive yefilimu ephezulu ye-AC, i-elecrones eveliswe ngaphakathi inokutsala kwi-tunnel ukusuka kwindawo yokufaka. After obtaining sufficient kinetic energy, electrons collide with the luminescent center, producing excitons and emitting light. Ngenxa yokungakwazi ukwenza i-elektrons ngaphandle kwe-electrode, ukuqaqamba kunye nokusebenza kakuhle kwezi zixhobo kusemgangathweni kwezi zixhobo kwicandelo lokukhanyisa kunye nokubonisa.
Ukwenzela ukuphucula intsebenzo yayo, abantu bayile i-belsts ye-elektroniki kunye ne-faker enye ye-inshurensi (jonga umfanekiso ongezelelweyo 2B). Kolu sakhiwo, ngexesha lomjikelo onesiqingatha se-AC Drive, umthwali ophetheyo ugcinwe ngqo kwi-elektroni engaphandle; Ukukhutshwa kokukhanya okukuko kunokubonwa ngokuphindaphindwa ngolunye uhlobo lomqhubi ohlawulelwayo owenziwe ngaphakathi. Nangona kunjalo, ngexesha lomjikelo onesiqingatha se-AC Drive, abathwali abanamatyala abathatyathwe baya kukhutshwa kwisixhobo kwaye ke abayi kukhutshwa kuyo kuphela umjikelo wokuqhuba, ukusebenza kakuhle kwesi sixhobo se-AC sezantsi kuneso sixhobo se-DC. Ukongeza, ngenxa yeempawu zokuxhobisa kwezixhobo, ukusebenza ngombane kwezixhobo ze-CA ze-AC.
Kutshanje, umntu othile ucebise isixhobo se-elektroniki ye-elektroniki enokusebenza rhoqo kwi-50 hz / 60 hz. Esi sixhobo siqulathe izixhobo ezimbini ze-DC (jonga umfanekiso 2c). Ngokujikeleza ngombane kwi-electrodes eqongeni yezixhobo ezibini kunye nokudibanisa i-coplanar esezantsi kwimithombo yamandla e-AC ye-AC, ezi zixhobo zimbini zingavulwa. Ukusuka kwimbono yesiphaluka, le sixhobo se-AC-DC ifunyanwa ngokudibanisa isixhobo esidlulayo kunye nesixhobo esibuyiselweyo ngothotho. Xa isixhobo sangaphambili sivuliwe, isixhobo esibuyiselweyo sicinyiwe, sisebenza njengomxhasi. Ngenxa yobukho bokuxhathisa, ukusebenza kakuhle kwe-elektrosoccence kuphantsi. Ukongeza, izixhobo zokukhupha ukukhanya kwe-Ac zinokusebenza kwi-voltage ephantsi kwaye azinakho ukudityaniswa ngqo ne-110 v / 220 v Umbane wasekhaya. Njengoko kubonisiwe kwinani elongezelelweyo 3 kunye neTheyibhile yoNyiki-mali yoku-1, ukusebenza (ukukhanya kunye nokusebenza kwamandla) Izixhobo ze-AC-DC ze-ACC ze-AC-DC iphantsi kuneso sixhobo se-AC se-AC. Ukuza kuthi ga ngoku, akukho sixhobo samandla se-AC-DC esinokuqhutywa ngokuthe ngqo ngombane wekhaya nge-110 v / 220 v, i-HZ / 60 HZ / i-HZPAN yama-HZ, kwaye inobume obuphezulu kunye ne-wospan ende kunye ne-wospan ephezulu.
I-chen yokutshintsha kunye neqela lakhe kwiDyunivesithi yaseMazantsi eSayensi kunye neTekhnoloji sele iphuhlise uthotho lwe-Dot Dot Light Liting Diode i-Diode ikhuphe i-iIndim ye-Indim ye-Iimy ye-Iimc efikelelayo njengombane ophakathi. I-Diode inokusebenza phantsi komjikelo oqinisekileyo nongalunganga wemijikelezo ekhoyo, enemisebenzi yangaphandle ye-20.09% ne-21.15%, ngokulandelelana. Ukongeza, ngokudibanisa izixhobo ezininzi ezixhumeneyo, iphaneli inokuqhutywa ngokuthe ngqo ngamandla ee-AC zekhaya ngaphandle kwesidingo se-BREGLET ye-RED. Iplagi ephucukileyo kwaye idlale iphaneli ye-DOT ye-DOT inokuvelisa imithombo yoqoqosho, esebenzayo, efanelekileyo, kunye nezinzileyo ezinokuxhonywa ngokuthe ngqo umbane we-AC.
