Kunezinhlobo eziningi zamandla kagesi we-LED.Izinga kanye nentengo yezinto ezihlukahlukene zamandla zihluka kakhulu.Lokhu futhi kungenye yezinto ezibalulekile ezithinta ikhwalithi yomkhiqizo kanye nentengo.Ukunikezwa kwamandla kagesi we-LED ngokuvamile kungahlukaniswa ngezigaba ezintathu, ukushintsha umthombo wamanje ongashintshi, ukunikezwa kwamandla kagesi we-IC olayini, kanye nokunikezwa kwamandla okushiya phansi amandla okumelana.
1. Umthombo wamanje oshintshayo usebenzisa i-transformer ukuze uguqule i-voltage ephezulu ibe yi-voltage ephansi, futhi yenza ukulungisa nokuhlunga ukuze kukhishwe amandla aqondile we-voltage ephansi ezinzile.Umthombo wamanje oshintshayo oshintshayo uhlukaniswe ukunikezwa kwamandla okukodwa kanye nokunikezwa kwamandla okungahlukanisiwe.Ukuhlukaniswa kubhekisela ekuhlukaniseni okukhipha amandla aphezulu naphansi, futhi ukuphepha kuphezulu kakhulu, ngakho-ke imfuneko yokufakwa kwegobolondo ayiphezulu.Ukuphepha okungezodwa kubi kakhulu, kodwa izindleko ziphansi.Izibani zendabuko ezonga amandla zisebenzisa ugesi ongahlukanisiwe futhi zisebenzisa igobolondo lepulasitiki elivalekile ukuze livikeleke.Ukuphepha kwamandla okushintsha kuphakeme kakhulu (ngokuvamile okukhiphayo kuyi-voltage ephansi), futhi ukusebenza kuzinzile.Okubi ukuthi isifunda siyinkimbinkimbi futhi intengo iphezulu.Ukunikezwa kwamandla okushintshayo kunobuchwepheshe obuvuthiwe nokusebenza okuzinzile, futhi okwamanje kungumthombo wamandla ojwayelekile wezibani ze-LED.
2. Ukunikezwa kwamandla kalayini we-IC kusebenzisa i-IC eyodwa noma ama-IC amaningi ukusabalalisa i-voltage.Kunezinhlobo ezimbalwa zezingxenye ze-elekthronikhi, isici samandla kanye nokusebenza kahle kokunikezwa kwamandla kuphezulu kakhulu, ayikho i-electrolytic capacitor edingekayo, impilo ende kanye nezindleko eziphansi.Okubi ukuthi i-voltage ephezulu ephumayo ayihlukanisiwe, futhi kune-stroboscopic, futhi indawo ebiyelwe iyadingeka ukuze ivikelwe ekushayweni kukagesi.Bonke basebenzisa amandla kagesi e-IC emakethe bathi awekho ama-electrolytic capacitor nempilo ende kakhulu.Ukunikezwa kwamandla kagesi e-IC kunokwethenjelwa okuphezulu, ukusebenza kahle okuphezulu kanye nezinzuzo zezindleko eziphansi, futhi kungumthombo wamandla we-LED ofanele esikhathini esizayo.
3. Ukunikezwa kwamandla okusuka phansi kwe-RC kusebenzisa i-capacitor ukuze kunikeze amandla okushayela ngokushaja nokukhipha kwawo.Isifunda silula, izindleko ziphansi, kodwa ukusebenza kumpofu, futhi ukuzinza kumpofu.Kulula kakhulu ukushisa i-LED lapho i-voltage yegridi ishintshashintsha, futhi okukhiphayo kungu-high-voltage okungahlukanisiwe.Igobolondo elivikelayo lokuvikela.Isici samandla aphansi nempilo emfushane, ngokuvamile ifaneleka kuphela imikhiqizo yamandla aphansi eyongayo (ngaphakathi kuka-5W).Ngemikhiqizo enamandla amakhulu, ukukhishwa kwamanje kukhulu, futhi i-capacitor ayikwazi ukunikeza yamanje enkulu, ngaphandle kwalokho kulula ukuyishisa.Ngaphezu kwalokho, izwe linezidingo zesici samandla amalambu anamandla amakhulu, okungukuthi, isici samandla esingaphezu kuka-7W siyadingeka ukuba sibe ngaphezu kuka-0.7, kodwa amandla okunciphisa amandla okwehla akude nokufinyelela (imvamisa phakathi 0.2-0.3), ngakho-ke imikhiqizo yamandla aphezulu akufanele isetshenziswe ukunikezwa kwamandla okusuka phansi kwe-RC.Emakethe, cishe yonke imikhiqizo esezingeni eliphansi enezidingo eziphansi isebenzisa amandla e-RC asuka phansi, futhi eminye imikhiqizo esezingeni eliphansi, enamandla amakhulu iphinde isebenzisa amandla e-RC ehlayo.
