Ulwakhiwo lwe-chip ye-LED

Ubume be-chip ye-LED: Kutshanje ndifunde ulwazi oluninzi olunxulumene ne-LED, ngokufutshane ukwazisa ubume kunye nenkqubo yokuvelisa i-chip ye-LED ukunceda ukuqonda uphuhliso lweenkampani ezinxulumene ne-LED kunye nethemba lophuhliso. I-chip ye-LED iqulethe izinto ezimbini eziphambili, enye ifilimu yokwandisa i-LED -i-substrate yesafire engezantsi kumfanekiso ongentla kunye ne-Nitrodes (GAN) i-buffer layer kwi-substrate; Kwaye i-PN electrode layer. Ke ngoko, iitshiphusi ze-LED zibandakanya iinkqubo ezintathu zokuvelisa: ukukhula kweshiti elikhanyayo, ukukhula kwe-chip kunye nokuveliswa, ukupakishwa kwe-chip. Phakathi kweenkqubo ezintathu ezingentla, umxholo wobugcisa bokukhula kwezilayi zangaphandle ziphezulu, ukuveliswa kwe-chip kukwesibini, kunye nokupakishwa okwesibini. Imodyuli ye-LED kukulungiselela i-LED (i-light-emitting diode) ngokuhambelana nemithetho ethile kwaye uyifake. I-LED yangaphandle yangaphandle yeshidi, kunye nezinye iimveliso zokusetyenzwa kwamanzi, yimodyuli ye-LED. Ngokutsho kokutywinwa, inokwahlulwa ibe ziindidi ezimbini: ingenamanzi kwaye ayinamanzi. Iimodyuli zokungangeni manzi kunye neemodyuli ezingenamanzi zihluke kakhulu ngokusingqongileyo kwesicelo. Ngokuqhelekileyo, iimodyuli ze-LED ezingenamanzi zingasetyenziselwa ukukhanya kwangaphandle kunye nokusetyenziswa kokukhangisa. Yimalini ukwandiswa kwe-LED? Ukusetyenziswa kokusingqongileyo, kungekhona iimodyuli ezingenamanzi zisetyenziswa kakhulu ngaphakathi. Ngokwemilo ye-LED, imodyuli ye-LED yahlulwe yaba: imodyuli ye-LED ethe ngqo, Imodyuli ye LED, umfanekiso we LED. Ubungakanani be-chip ye-LED bohlulwe ngokweetshiphusi ezincinci zamandla, iitshiphusi zamandla aphakathi kunye ne-high-power chips ngokwamandla zinokwahlulwa zibe ziichips ezincinci zamandla. Ngokweemfuno zabathengi, inokwahlulwa ibe yinqanaba le-tube enye, inqanaba ledijithali, inqanaba lematrix yamachaphaza, ukukhanya komhombiso kunye nezinye iindidi. Ngokubhekiselele kubungakanani obuthile be-chip, kuxhomekeke kwinqanaba lokwenyani lemveliso yabenzi beetshiphu ezahlukeneyo. Akukho mfuneko zikhethekileyo. Ngethuba nje inkqubo idlula, iitshiphusi ezincinci zinokunyusa imveliso yeyunithi kwaye zinciphise iindleko. Ifilimu yolwandiso lwe-LED ye-Zhanjiang kunye nokusebenza kweefoto zombane akuyi kutshintsha ngokusisiseko. Ukusetyenziswa kwangoku kwetshiphu eneneni inxulumene noxinaniso lwangoku lokuqukuqela kwitshiphu. I-chip isebenzisa yangoku encinci, i-ambassador ye-chip inkulu, abavelisi befilimu be-LED, iyunithi yabo yoxinaniso lwangoku luphantse lufane. Ukuqwalasela ukuba ukutshatyalaliswa kobushushu kuyingxaki ephambili phantsi kombane omkhulu, ukukhanya kwayo okukhupha ukukhanya kuphantsi kuneyona misinga encinci. Ngakolunye uhlangothi, ngenxa yokunyuka kwendawo, ukuxhathisa umzimba we-chip kuya kuncipha, ngoko i-voltage ye-positive direction iya kuncipha. Buyela kwinyathelo langaphambili ukuprinta eli phepha
