Bandhiga elektaroonigga ah ee LED waa nooc ka mid ah aaladaha kantaroolka ee hadda jira, darawalka LED-ku dhab ahaantii waa awoodda wadista LED-ka, taas oo ah, aaladda wareegga u beddeleysa awoodda AC ilaa koronto joogto ah ama koronto joogto ah DC.Si ka duwan nalalka iftiinka ee caadiga ah, bandhigyada elektaroonigga ah ee LED waxay si toos ah ugu xiran yihiin 220V AC dhexda.Nalalka LED-yadu waxay leeyihiin shuruudo adag oo loogu talagalay awoodda wadista, iyo korantadooda shaqadu guud ahaan waa 2 ~ 3V korantada DC, iyo wareegga beddelka adag waa in la qaabeeyaa.Nalalka LED-ka ee ujeedooyinka kala duwan waa in lagu qalabeeyaa qalab koronto oo kala duwan.
Aaladaha LED-ku waxay leeyihiin shuruudo aad u sarreeya oo loogu talagalay hufnaanta beddelka, awood wax ku ool ah, saxnaanta joogtada ah ee hadda jirta, nolosha awoodda, iyo waafaqsanaanta korantada ee awoodda wadista LED.Awoodda wadida wanaagsan waa in ay tixgelisaa arrimahan, sababtoo ah awoodda wadistu waxay ku jirtaa dhammaan nalka LED-ka.Doorku waa mid muhiim u ah sida qalbiga aadanaha oo kale.Hawsha ugu weyn ee darawalka LED-ku waa in uu koronto AC u beddelo koronto joogto ah oo DC ah, isla markaana la dhammaystiro ku-habboonaanta tamarta LED-ka iyo hadda.Hawsha kale ee darawalka LED-ka ayaa ah in la sameeyo culeyska hadda ee LED-ka oo lagu xakameeyo heer horay loo qorsheeyay iyada oo ay saameynayaan arrimo kala duwan.
Waxaa jira shuruudo ay LED-ku soo bandhigaan elektaroonik ah si ay u iftiimiyaan iftiinka.Korontada hore waxa lagu dabaqaa labada daraf ee isgoysyada PN, si ay isku xidhka PN lafteedu u samaysmaan heer tamar (runtii heerar tamar ah oo taxane ah), iyo electrons-ku waxa ay ku boodaan heerkan tamarta oo ay dhaliyaan sawiro si ay u iftiimiyaan iftiinka.Sidaa darteed, korantada lagu dabaqo is-goysyada PN ayaa looga baahan yahay inay kaxayso LED-ka si ay u iftiimiso iftiinka.Intaa waxaa dheer, sababtoo ah LED-yadu waa qalab semiconductor ah oo sifo-xasaasi ah leh oo leh sifooyin heerkul xun, waxay u baahan yihiin in la dejiyo oo la ilaaliyo inta lagu jiro habka codsiga, taas oo keenaysa fikradda LED "drive".
Qof kasta oo la soo xiriiray LED-yada wuxuu ogyahay in sifooyinka hore ee volt-ampere ee LED-yadu ay aad u kacsan yihiin (volt-ka firfircooni hore waa mid aad u yar), wayna adagtahay in la siiyo tamarta LED-ka.Si toos ah looguma kicin karo il koronto sida nalalka caadiga ah ee shidan.Haddii kale, korontadu Iyadoo ay yara korodhay isbedbedelka, hadda ayaa kor u kacaya ilaa heerka LED-gu uu gubi doono.Si loo dejiyo wakhtiga shaqada ee LED-ka oo loo hubiyo in LED-ku si caadi ah oo la isku halleyn karo u shaqayn karo, wareegyada wadista LED-yada kala duwan ayaa soo baxay.
