Izixazululo ze-LED ezihlukanisiwe nezingezodwa ngayinye inezici zayo kanye nezimo zohlelo lokusebenza kubuchwepheshe bokukhanyisa kwe-LED.Nakhu ukuhlaziya okuningiliziwe kwazo zombili izinketho:
1. Isixazululo se-LED esingasodwa
A. Incazelo kanye nezici
Ukuhlukaniswa kukagesi:Isici esiyinhloko sesisombululo se-LED esihlukanisiwe ukuhlukaniswa kukagesi phakathi kokufakwayo nokuphuma kokuphela. Lokhu kuhlukaniswa kungafinyelelwa ngama-transformers noma ezinye izingxenye zokuzihlukanisa, ngaleyo ndlela kunciphisa kakhulu ukuphazamiseka komsindo kagesi okubangelwa ukuthintana okuqondile kanye nokulimala kwezingxenye zesifunda ezibangelwa izici ezimbi ezifana nokushaywa kombani ngesikhathi senqubo yokudlulisa isignali, ukuthuthukisa ukuphepha nokuthembeka kwemishini.
Ukuphepha:Ngenxa yokuba khona kokuhlukaniswa kukagesi, isisombululo se-LED esisodwa sinezinzuzo ezibalulekile ekuphepheni, ezingavimbela ngempumelelo ingozi yokushaqeka kukagesi futhi zivikele ukuphepha kwabasebenzisi kanye nemishini.
B. Izihloko zesekethe ezivamile
Ama-topology esekethe ye-LED ejwayelekile ahlukanisiwe afaka izinto zamandla e-flyback, izinsiza zamandla ezishintshayo ezifakiwe, amandla okushintsha ahlukanisiwe, iziguquli ze-resonant eziseceleni kwesibili, abamukeli bangaphambili, izilawuli zamandla ezixubile, njll.
Ngayinye yalezi topology inezici zayo, kodwa lokho abafana ngakho ukuthi bonke bafinyelela ukuhlukaniswa kukagesi phakathi kokufaka nokuphumayo.
C. Izimo zohlelo lokusebenza
Izixazululo ze-LED ezihlukanisiwe zivame ukusetshenziswa ezimeni ezinezidingo zokuphepha eziphezulu, ezifana nemikhiqizo ye-LED yamandla kagesi aphezulu kanye nezinhlelo zokusebenza zezimboni ezidinga ukuhlukaniswa okuqinile kukagesi.
D. Amacala okufaka isicelo
2. Isixazululo se-LED esingahlukanisiwe
A. Incazelo kanye nezici
Akukho ukuhlukaniswa kukagesi:Izixazululo ze-LED ezingahlukanisiwe azinakho ukuhlukaniswa kukagesi phakathi kokufaka nokuphumayo. Lesi sixazululo sivame ukuba nesakhiwo sesifunda esilula kanye nokusebenza kahle okuphezulu kokuguqulwa, kodwa uma sisetshenziswa, kuyadingeka ukuqinisekisa ukuthi kunebanga elithile lokuzihlukanisa phakathi kokuphela kokufaka nokuphela kokuphumayo noma ukuthatha ezinye izinyathelo zokuphepha ukuqinisekisa ukuphepha kwemishini kanye abasebenzi.
Izindleko nokusebenza kahle:Ngenxa yesakhiwo sesifunda esilula, isisombululo se-LED esingasodwa sinezinzuzo ezithile ezindlekweni. Ngesikhathi esifanayo, ukusebenza kahle kwayo kokuguqulwa kuvame ukuba phezulu, okuzuzisa ukonga amandla nokunciphisa izindleko.
B. Izihloko zesekethe ezivamile
Ama-toplogies esekethe ye-LED evamile engahlukanisiwe ahlanganisa idrayivu eqondile, ukunikezwa kwamandla ochungechunge, ukunikezwa kwamandla kagesi esihlukanisi se-voltage, njll. Lawa ma-topology alula futhi afanele izinhlelo zokusebenza ezinezindleko eziphezulu kanye nezidingo zesikhala.
C. Izimo zohlelo lokusebenza
Izixazululo ze-LED ezingahlukanisiwe zivame ukusetshenziswa ezimeni ezinezidingo zokuphepha eziphansi kanye nezidingo eziqinile zezindleko nendawo, njengezibani ezincane ezifana namashubhu e-LED fluorescent.
D.Ongahlukanisiwe

Kafushane, izixazululo ze-LED ezihlukanisiwe nezingezodwa ngayinye inezinzuzo zayo kanye nebubi bayo, futhi kufanele ikhethwe ngokuya ngezidingo nezimo ezithile ezisetshenziswayo. Ngokuthuthuka kobuchwepheshe kanye nokwehliswa kwezindleko, lezi zixazululo ezimbili kulindeleke ukuthi zisetshenziswe futhi zithuthukiswe emikhakheni eyengeziwe esikhathini esizayo.
Singumkhiqizi osebenza ngokukhethekile ekukhiqizeni ama-transformer aphezulu naphansi, ama-inductors, ama-magnetic cores, nezinto zamandla zomshayeli we-LED.
Siyakwamukela ukuvakashelaikhasi lomkhiqizoukuthenga.
