Umboniso we-elektroniki we-LED luhlobo lwesixhobo solawulo lwangoku, umqhubi we-LED ngamandla okuqhuba e-LED, oko kukuthi, isixhobo sesekethe esiguqula amandla e-AC abe ngamandla akhoyo akhoyo okanye angatshintshiyo e-DC.Ngokungafaniyo ne-incandescent bulbs eziqhelekileyo, iziboniso zombane ze-LED zinokuqhagamshelwa ngokuthe ngqo kwi-220V AC mains.Ii-LED zineemfuno eziphantse zibe rhabaxa zamandla okuqhuba, kwaye amandla ombane azo asebenzayo ngokuqhelekileyo yi-2 ~ 3V DC yombane, kwaye isekethe yokuguqula entsonkothileyo kufuneka iyilwe.Izibane ze-LED ngeenjongo ezahlukeneyo kufuneka zixhotyiswe ngeeadaptha zamandla ezahlukeneyo.

Izixhobo ze-LED zineemfuno eziphezulu kakhulu zoguqulo olusebenzayo, amandla asebenzayo, ukuchaneka okuthe rhoqo, ubomi bamandla, kunye nokuhambelana kombane wombane we-LED.Amandla okuqhuba kakuhle kufuneka athathele ingqalelo le miba, kuba amandla okuqhuba akwisibane sonke se-LED.Indima ibaluleke njengentliziyo yomntu.Umsebenzi ophambili womqhubi we-LED kukuguqula i-voltage ye-AC ibe ngumbane oqhubekayo we-DC yangoku, kwaye kwangaxeshanye ugqibezele ukudibanisa kunye nombane we-LED kunye nokhoyo.Omnye umsebenzi womqhubi we-LED kukwenza umthwalo wangoku we-LED olawulwa kwinqanaba elilungiselelwe ngaphambili phantsi kwefuthe lezinto ezahlukeneyo.

Kukho iimeko zokuba isiboniso sombane se-LED sikhuphe ukukhanya.I-voltage eya phambili isetyenziswe kuzo zombini iziphelo ze-PN junction, ukwenzela ukuba i-PN junction ngokwayo yenze inqanaba lamandla (eneneni uchungechunge lwamanqanaba ombane), kwaye ii-electron zixhuma kule nqanaba lamandla kwaye zivelise iifotoni ukuze zikhuphe ukukhanya.Ke ngoko, i-voltage esetyenziswa kuyo yonke i-PN junction iyafuneka ukuqhuba i-LED ukuze ikhuphe ukukhanya.Ngaphezu koko, ngenxa yokuba ii-LED zizixhobo ze-semiconductor ezithintekayo kunye neempawu zeqondo lokushisa elibi, kufuneka zizinziswe kwaye zikhuselwe ngexesha lenkqubo yesicelo, ngaloo ndlela zivelisa ingcamango ye-LED "drive".

Nabani na oye wadibana nee-LEDs uyazi ukuba iimpawu ze-volt-ampere zangaphambili ze-LED ziphezulu kakhulu (i-voltage eguquguqukayo yangaphambili incinci kakhulu), kwaye kunzima kakhulu ukubonelela amandla kwi-LED.Ayinakunikwa amandla ngokuthe ngqo ngumthombo wombane njengezibane eziqhelekileyo ze-incandescent.Ngaphandle koko, i-voltage Ngokunyuka okuncinci kwi-fluctuation, okwangoku kuya kunyuka kwinqanaba lokuba i-LED iya kutshiswa.Ukuze uzinzise ukusebenza kwangoku kwe-LED kunye nokuqinisekisa ukuba i-LED inokusebenza ngokuqhelekileyo kwaye ithembekile, kuye kwavela iisekethe ezahlukeneyo ze-LED.
