Okwangoku, abaninziIimveliso ze-LEDsebenzisa imowudi yokuqhuba yangoku ukuqhubaI-LED.Imowudi yoqhagamshelo lwe-LED ikwayila iindlela ezahlukeneyo zokunxibelelana ngokweemfuno zesekethe zangempela.Ngokubanzi, kukho iifom ezine: uthotho, ukuhambelana, umxube kunye noluhlu.

I-1, imo yochungechunge

Isekethe yolu luhlu lwendlela yokudibanisa ilula.Intloko kunye nomsila zidibene kunye.Ikhoyo ngoku ehamba nge-LED ngexesha lokusebenza kuhle kakhulu.Ngenxa yokuba i-LED sisixhobo sohlobo lwangoku, inokuqinisekisa ngokusisiseko ukuba ukukhanya okukhanyayo kwe-LED nganye kuyahambelana.Imowudi yokudibanisa i-LED ineenzuzo zesekethe elula kunye nokudibanisa okulula.Kodwa kukho kwakhona ukungonakali ezibulalayo, oko kukuthi, xa omnyeii-LEDsinesiphako sesekethe evulekileyo, iya kubangela ukuba yonke intambo yesibane se-LED iphume kwaye ichaphazele ukuthembeka kokusetyenziswa.Ngoko ke, kuyimfuneko ukuqinisekisa umgangatho obalaseleyo we-LED nganye, ukwenzela ukuba ukuthembeka kuya kuphuculwa ngokufanelekileyo.

Kuyafaneleka ukuba uqaphele ukuba ukuba i-LED ye-voltage eqhubekayo yokuqhuba umbane isetyenziselwa ukuqhuba i-LED, umbane wesiphaluka uya kwanda xa i-LED ifutshane.Xa ixabiso elithile lifinyelelwe, i-LED iya konakaliswa, ibangele umonakalo wazo zonke ii-LED ezilandelayo.Nangona kunjalo, ukuba umbane we-LED oqhubekayo wangoku usetyenziselwa ukuqhuba i-LED, okwangoku ngoku kuya kuhlala kungatshintshi xa i-LED ifutshane, ayinayo impembelelo kwii-LED ezilandelayo.Kungakhathaliseki ukuba yeyiphi indlela yokuqhuba, xa i-LED ivulekile isiphaluka, isiphaluka sonke asiyi kukhanyiswa.

2, Imo ehambelanayo

Imodi ehambelanayo ibonakaliswe ngokudibanisa okufanayo kwentloko ye-LED kunye nomsila, kwaye i-voltage ethathwe yi-LED nganye iyalingana ngexesha lokusebenza.Nangona kunjalo, okwangoku akufuneki ukuba kulingane, nakwii-LED zemodeli efanayo, ukucaciswa kunye nebhetshi.Oku kungenxa yenkqubo yemveliso kunye nezinye izizathu.Ke ngoko, ukuhanjiswa okungalinganiyo kwangoku kwe-LED nganye kunokunciphisa ubomi benkonzo ye-LED ngokugqithisileyo ngoku xa kuthelekiswa nezinye ii-LED, kwaye kulula ukutshisa ngokuhamba kwexesha.Isekethe yale ndlela yokudibanisa ehambelanayo ilula, kodwa ukuthembeka akukho phezulu.Ngokukodwa xa kukho inani elikhulu le-LED, ithuba lokungaphumeleli liphezulu.

Kuyaphawuleka ukuba i-voltage efunekayo kuqhagamshelo oluhambelanayo iphantsi, kodwa ngenxa yokuhla kombane ohlukeneyo we-LED nganye, ukukhanya kwe-LED nganye kwahlukile.Ukongezelela, ukuba i-LED enye ijikeleziwe emfutshane, isiphaluka sonke siya kuba sifutshane, kwaye ezinye ii-LED azikwazi ukusebenza ngokuqhelekileyo.Kwisekethe evulekileyo ekhokelwayo, ukuba i-drive eqhubekayo yangoku isetyenziswa, ikhoyo ngoku eyabelwe ii-LED ezishiyekileyo iya kwanda, nto leyo enokukhokelela kumonakalo wee-LED eziseleyo, nangona kunjalo, ukusetyenziswa kwe-voltage drive rhoqo akuyi kuchaphazela ukusebenza kwesiqhelo. yonke isekethe ye-LED.

3. Imo yeHybrid

Uxhulumaniso lweHybrid ludibaniso lwechungechunge kunye nokuhambelana.Okokuqala, ii-LED ezininzi ziqhagamshelwe kuthotho, kwaye emva koko ziqhagamshelwe ngokufanayo kuzo zombini iziphelo zonikezelo lwamandla okuqhuba i-LED.Xa ii-LED zihambelana ngokusisiseko, le ndlela yokudibanisa yamkelwa ukwenza i-voltage yawo onke amasebe ngokusisiseko ilingane kunye nokuhamba kwangoku kwisebe ngalinye ngokusisiseko.

Kuyaphawuleka ukuba imowudi yokudibanisa i-hybrid isetyenziswa ikakhulu kwimeko yee-LED ezininzi, kuba le ndlela iqinisekisa ukuba ukusilela kwe-LED kwisebe ngalinye kuchaphazela kuphela ukukhanya okuqhelekileyo kweli sebe kakhulu, okuphucula ukuthembeka xa kuthelekiswa nokukhanya okuqhelekileyo. uchungechunge olulula kunye nemo yodibaniso oluhambelanayo.Okwangoku, le ndlela isetyenziswa ngokubanzi kwizibane ezininzi ze-LED eziphezulu zokufikelela kwiziphumo ezisebenzayo kakhulu.

4. Imo yoluhlu

Ifom ephambili yendlela yoluhlu kukuba: isebe lithatha ii-LED ezintathu njengeqela kwaye liqhagamshelwe kwi-UA, Ub kunye ne-UC yokuphuma kwee-terminals zemveliso yomqhubi ngokulandelanayo.Xa ii-LED ezintathu kwisebe ziqhelekile, ii-LED ezintathu ziya kukhanya ngexesha elifanayo;Nje ukuba i-LED enye okanye ezimbini zisilele kwaye zivule isekethe, ukusebenza okuqhelekileyo kwe-LED enye kunokuqinisekiswa.Ngale ndlela, ukuthembeka kweqela ngalinye le-LED kunokuphuculwa kakhulu, kwaye ukuthembeka okupheleleyo kwe-LED yonke kunokuphuculwa.Ngale ndlela, amaqela amaninzi okufakelwa kwamandla okufakelwa afunekayo ukuze kuphuculwe ukuthembeka komsebenzi we-LED kunye nokunciphisa izinga lokungaphumeleli kwesiphaluka jikelele.
