1, Indlela yokudibanisa yochungechunge

Le ndlela yokudibanisa uchungechunge inesekhethi elula, enentloko kunye nomsila odibeneyo. Ikhoyo ngoku ehamba nge-LED ngexesha lokusebenza iyahambelana kwaye ilungile. Njengoko i-LED sisixhobo sohlobo lwangoku, inokuqinisekisa ngokusisiseko ukuba ukukhanya okukhanyayo kwe-LED nganye kuyahambelana. Isekethe isebenzisa okuIndlela yokudibanisa i-LEDilula kwaye ikulungele ukudibanisa. Kodwa kukwakho ne-drawback ebulalayo, yokuba xa enye yee-LED ifumana impazamo yesekethe evulekileyo, iya kubangela ukuba yonke intambo ye-LED iphume, echaphazela ukuthembeka kokusetyenziswa. Oku kufuna ukuqinisekisa ukuba umgangatho we-LED nganye ugqwesile, ngoko ke ukuthembeka kuya kuphuculwa ngokuhambelanayo.

Kubalulekile ukuqaphela ukuba iUmbane oqhubekayo we-LEDunikezelo lwamandla okuqhuba lusetyenziselwa ukuqhuba i-LED, xa i-LED enye ifutshane, iya kubangela ukwanda kwesekethe yangoku. Xa ixabiso elithile lifinyelelwe, i-LED iya konakaliswa, okubangela ukuba zonke ii-LED ezilandelayo zonakaliswe. Nangona kunjalo, ukuba umbane we-LED oqhubekayo wangoku usetyenziselwa ukuqhuba i-LED, okwangoku iya kuhlala ingatshintshi xa i-LED enye ijikeleza ngokukhawuleza, kwaye ayiyi kuchaphazela ii-LED ezilandelayo. Kungakhathaliseki ukuba yeyiphi indlela yokuqhuba, xa i-LED ivula, isiphaluka sonke asiyi kukhanyiswa.

2. Indlela yoqhagamshelwano enxuseneyo

Isici soxhumo oluhambelanayo kukuba i-LED ixhunyiwe ngokufana ukusuka entloko ukuya emsila, kwaye i-voltage ethathwe yi-LED nganye ngexesha lokusebenza ilingana. Nangona kunjalo, okwangoku akunako ukulingana, nakwii-LED zemodeli efanayo kunye nebhetshi yenkcazo, ngenxa yezinto ezifana nemveliso kunye neenkqubo zokuvelisa. Ke ngoko, ukusasazwa okungalinganiyo kwangoku kwi-LED nganye kunokubangela ukuba ubomi be-LED obugqithise ngoku bunciphe xa kuthelekiswa nezinye ii-LED, kwaye ngokuhamba kwexesha, kulula ukutshisa. Le ndlela yoxhulumaniso oluhambelanayo inomjikelezo olula, kodwa ukuthembeka kwayo akukho phezulu, ngakumbi xa kukho ii-LED ezininzi, kunokwenzeka ukuba ukusilela kuphezulu.

Kuyafaneleka ukuba uqaphele ukuba indlela yokudibanisa i-parallel idinga i-voltage ephantsi, kodwa ngenxa yokuhla kwe-voltage eyahlukileyo ye-LED nganye, ukukhanya kwe-LED nganye kuyahluka. Ukongezelela, ukuba i-LED enye ifutshane, isiphaluka sonke siya kuba sifutshane, kwaye ezinye ii-LED aziyi kusebenza kakuhle. Kwi-LED ethile evulekileyo ejikelezayo, ukuba i-drive yangoku isetyenziswa rhoqo, i-current eyabelwe ii-LED eziseleyo iya kwanda, enokubangela umonakalo kwii-LED ezisele. Nangona kunjalo, ukusebenzisa i-voltage drive rhoqo akuyi kuchaphazela ukusebenza okuqhelekileyo kwayo yonkeIsekethe ye-LED.

3. Indlela yokudibanisa iHybrid

Uxhulumaniso lweHybrid ludibaniso lwechungechunge kunye noqhagamshelwano oluhambelanayo. Okokuqala, ii-LED ezininzi ziqhagamshelwe kuthotho kwaye emva koko ziqhagamshelwe ngokunxuseneyo kuzo zombini iziphelo zombane womqhubi we-LED. Ngaphantsi kwemeko yokubambisana okusisiseko kwee-LEDs, le ndlela yokudibanisa iqinisekisa ukuba i-voltage yawo onke amasebe ilingana ngokusisiseko, kwaye i-current ejikelezayo kwisebe ngalinye nayo iyafana.

Kuyaphawuleka ukuba ukusetyenziswa koqhagamshelwano lwe-hybrid lusetyenziswa ikakhulu kwiimeko ezinenani elikhulu le-LED, kuba le ndlela iqinisekisa ukuba iimpazamo ze-LED kwisebe ngalinye zichaphazela kuphela ukukhanya okuqhelekileyo kwesebe kakhulu, okuphucula ukuthembeka xa kuthelekiswa nochungechunge olulula. kunye noqhagamshelwano olunxuseneyo. Okwangoku, izibane ezininzi ze-LED eziphezulu zisebenzisa le ndlela ukufezekisa iziphumo ezisebenzayo.

4. Indlela ye-Array

Ukuqulunqwa okuphambili kwendlela yoluhlu ngolu hlobo lulandelayo: amasebe aqulunqwe ngama-LED amathathu kwiqela, ngokulandelanayo.
