Umboniso we-LEDyenye yeenkalo zesicelo eziphambili ze-LED, eziphuhliswe ngokukhawuleza kwiminyaka yamuva.Ngoku,Ukubonisa isikrini se-LEDinobuchwephesha bemveliso kunye nexabiso eliphantsi, ngoko ke kunzima kwiinkampani zangaphandle ukuba zikhuphisane kwimarike yelizwe.Ngokwezibalo ezingaphelelanga, ngo-1998, bekukho ngaphezu kwe-150 abenzi besikrini se-LED e-China, eveliswe malunga ne-50000 yeemitha ezizikweri zazo zonke iintlobo zemiboniso, ukufikelela kwixabiso lemveliso ye-yuan eyi-1.4 yebhiliyoni.Ishishini le-LED lenze impumelelo ephawulekayo.Kwiminyaka yakutshanje, malunga nokwakhiwa kwemveliso, iteknoloji yokuvelisa, umgangatho wemveliso, inqanaba lemveliso yobuninzi, isabelo semarike, njl., ikufuphi neJapan, kwaye ibeka indawo yesithathu kwihlabathi emva kwe-United States ne-Japan kwi-industry ye-LED yehlabathi.Kule minyaka mihlanu idlulileyo, umndilili wokukhula ngonyaka ufikelele ngaphezu kwama-20%.Ngo-1997, iimveliso ze-optoelectronic ezilishumi eziphezulu zaseTaiwan zibekwe kwindawo yesine, ngexabiso lemveliso ye-SGD 18870 yezigidi.I-Epistar Corp iphuhlise ngempumelelo iitshiphusi ezibomvu, eziluhlaza kunye neziluhlaza okwesibhakabhaka kwizibane ezinombala ogcweleyo kunye neziboniso, ngokukhanya kokukhanya kwezi chips ezingaphezu kwe-70 mcd.Inkampani eyenza imveliso isebenzisa itekhnoloji ye-MOVPE ukuvelisa i-InGaAlp imathiriyeli yokukhanya okuqaqambileyo kunye neetshiphusi.ITaiwan ineenkampani ezisixhenxe ezivelisa iitshiphusi ze-LED, ezivelisa iitshiphusi ezahlukeneyo zemveli, ezibalelwa ngaphezulu kwe-70% yemveliso yehlabathi.
Ukusetyenziswa kweI-LEDixhaphake kakhulu.Ngenxa yombane ophantsi osebenzayo, ukusetyenziswa kwamandla aphantsi, imibala etyebileyo kunye nexabiso eliphantsi, yamkelwa ziinjineli zombane kunye nabaphandi besayensi.Kwiintsuku zokuqala, iimveliso zemveli zazinokukhanya okuphantsi kokukhanya, kwaye ukukhanya kokukhanya kwakuqhelekile ukuya kuninzi lwee-mcd.Zazifanelekile kwizicelo zangaphakathi, ezifana nezixhobo zasekhaya, izixhobo, izixhobo zonxibelelwano, ii-microcomputers kunye nezinto zokudlala.Ngenxa yophuhliso olukhulayo lwetekhnoloji yesicelo, amathuba amatsha okusebenza avele kwiimveliso zemveli.Izibane ezidumileyo zeKrisimesi ze-LED, kunye nemilo yazo inoveli, zizibane zeKrisimesi ezihlawulwa ngamadada, izibane zebhola ezinemibala kunye nezibane zefestile.Zimibalabala, azinakwaphuka, kwaye zikhuselekile kusetyenziso lwe-voltage ephantsi.Kutshanje, banemarike eyomeleleyo kuMzantsi-mpuma Asia, njengeHong Kong, yaye bamkelwa ngokubanzi ngabantu.Bagrogrisa kwaye batshintsha imarike ekhoyo yeKrisimesi ukuze bafumane izibane zombane.Uhlobo lwezihlangu ezikhazimlayo ezithandwayo ngabantwana, esebenzisa i-LED ukukhanyisa xa uhamba kwaye ulala.Ijonge kakhulu, kubandakanya ukukhanya kwe-monochromatic kunye nokukhanya kombala ombini.Ngokweemveliso zoshishino, izibane ze-LED zohlobo lwe-AD11 zisetyenziswa ngokubanzi kwiikhabhinethi zamandla.Ezi mveliso zisebenzisa ukuhlanganiswa kwe-chip ezininzi ukwenza umthombo wokukhanya, onemibala emithathu: obomvu, omthubi kunye nohlaza.Emva kokuba i-capacitor icinezelekile, i-220V kunye ne-280V yamandla ombane ingasetyenziswa.Ngokutsho komvelisi e Jiangsu, intengiso yonyaka yenkampani ifikelela ngaphezu kwe-10M, kwaye ifuna (200 ~ 300) iitshiphusi ze-M LED minyaka le.Imarike isenamandla okwandisa.Ngenxa yesalathiso esicacileyo esisebenzayo esikhanyayo, ubomi benkonzo ende, ukusetyenziswa kwamandla aphantsi kunye nezinye iimpawu, ithandwa kakhulu ngabasebenzisi kwaye inokutshintsha kungekudala zonke iintlobo ze-bubble ze-AD11.Ngelizwi, imarike yee-diode ezikhupha ukukhanya kwendabuko ayiyi kuphucula kuphela ngokukhula kweemveliso zesicelo sokuqala, kodwa ivule amathuba okuthengisa kwizicelo ezintsha.
