Yiziphi Izinzuzo ze-LED engena-AC uma iqhathaniswa Nemikhiqizo Yendabuko?

Ubuchwepheshe bokukhanyisa be-LED obusafufusa buthuthuka ngesivinini esikhulu. Idumile emphakathini ngokonga amandla aphezulu, ukuvikelwa kwemvelo okuluhlaza, nempilo ende. Ubuchwepheshe obusha nezixazululo ezintsha kuhlelo lokusebenza nazo sezivele. Idizayini yokukhanyisa i-LED ingahlanganisa izici zemithombo yokukhanya, njengemithombo yokukhanya, imithombo yokukhanya ebandayo, nokushintsha kombala, njll., nakanjani kuzoba inkambiso yemakethe yokukhanyisa. Eminyakeni yamuva nje, ngokuthuthuka okuqhubekayo kocwaningo lwe-LED ekukhetheni izinto kanye nobuchwepheshe bomklamo wezakhiwo, kuye kwaba khona ubuchwepheshe obusha be-AC Light -emitting diode AC -free LED. Ngombono omusha, ikhuthaze ubuchwepheshe bokukhanyisa kwe-LED obusebenzayo. I-AC-free LED ihlobene ne-DCLED yendabuko. Ayidingi ukudlula ukuguqulwa kwe-AC/DC, okungaxhunywa ngokuqondile kubuchwepheshe bokukhanyisa be-LED obusetshenziswa ku-220V (noma i-110V). Isihluthulelo sobuchwepheshe be-LED obungenayo i-AC ukuhlelwa okukhethekile kanye nenhlanganisela yezinhlamvu ze-LED emaphaketheni. Ngesikhathi esifanayo, izici ze-diode zefindo le-LEDPN nazo ziyalungiswa. Ngenqubo yokukhiqiza ye-semiconductor ubuchwepheshe be-Crystal, futhi yamukele inqubo yokuhlelwa kwe-matrix enyakazayo ukuze kwakhiwe umjikelezo webhuloho, ukuze i-AC yamanje ivulwe ngezindlela ezimbili, kanye nokukhishwa kokukhanya. Ukuhlelwa kwezinhlamvu kuyizinhlamvu zezinhlamvu ze-LED ezingenamshayeli we-AC zisebenzisa umdwebo wohlelo lokuhlelwa kwe-matrix. Empeleni isithombe sokuhlela okusanhlamvu kwe-LED engena-AC, i-AC-free LED okusanhlamvu okusanhlamvu ukuze kukhanye ngemva kokuxhuma ukuxhumana, ngakho-ke imikhondo eholayo emibili kuphela edinga Ukungenisa kanye nomthombo wokuxhumana ongasebenza ngokukhazimulayo. Umgomo wokusebenza womthombo wokukhanya we-LED wamahhala we-AC wakhiwe inqubo yokuhlelwa kwe-matrix egxilile nge-microlymation ye-LED. Izinhlamvu, uhhafu ophozithivu - eduze komugqa wangempela wokuxhumana, izinhlamvu ze-LED zengalo yebhuloho elingu-3 ziyakhazimula, uhhafu ongemuhle -uhambisana nomugqa wamachashazi, kanye nezinhlamvu ze-LED ezinezingalo zebhuloho ezi-3 ziyakhazimula. Iyacwebezela, uma kuqhathaniswa nezinhlamvu ze-LED engalweni yebhuloho ngesikhathi esifanayo, kanye nezinhlamvu ze-LED engalweni yebhuloho elimaphakathi bezilokhu zikhazimula ngenxa yokwabelana. I-AC-free LED incane futhi ivame ukusetshenziselwa izinkomba ezincane zezimboni nezabantu; high -voltage futhi low -current in -depth benefits inqoba inkinga yokulahlekelwa okuphezulu komugqa lapho usebenzisa i-DCLED, okuncike ekuqhubekeni kokunikezwa kwamandla kagesi; Inkinga ye-ESD ye-LED engeyona eye-electrostatic; sebenzisa ubuchwepheshe be-micro-grain ukuthuthukisa kakhulu ukusebenza kahle kokukhanyisa; ngenxa yokuthuthukiswa kwesici samandla nokulawula okuphansi kwamanje, embonini yokukhanyisa okuvamile kanye nemboni yephaneli ye-backlight ye-LCD, kubuye kube ubuchwepheshe obusha. Njengamanje, i-AC -free LED isabuyekezwa ngokuqhubekayo mayelana nokukhanya okukhazimulayo, amandla, njll., kodwa ukufinyelela kwama-LED angenayo i-AC kulula futhi kubiza kancane, ukusebenza kahle okuphezulu. Isitifiketi sobuchwepheshe se-AC-free LED siyathuthuka. Kukholakala ukuthi esikhathini esizayo esiseduze, ukukhanya okuphezulu, amandla aphezulu, nemikhiqizo ebiza kancane izotholakala ngobuningi.
