Chiwonetsero chamagetsi cha LED ndi mtundu wa chipangizo chamakono chowongolera, dalaivala wa LED ndiye mphamvu yoyendetsa ya LED, ndiye kuti, chipangizo chozungulira chomwe chimasintha mphamvu ya AC kukhala mphamvu yamagetsi yamagetsi ya DC yosasintha.Mosiyana ndi mababu wamba a incandescent, zowonetsera zamagetsi za LED zitha kulumikizidwa mwachindunji ndi mains 220V AC.Ma LED ali ndi zofunika pafupifupi zovuta pakuyendetsa magetsi, ndipo mphamvu yawo yogwirira ntchito nthawi zambiri imakhala 2 ~ 3V DC voliyumu, ndipo makina osinthira ovuta amayenera kupangidwa.Nyali za LED pazolinga zosiyanasiyana ziyenera kukhala ndi ma adapter amagetsi osiyanasiyana.

Zida za LED zili ndi zofunika kwambiri pakusintha kwachangu, mphamvu zogwira ntchito, kulondola kwanthawi zonse, moyo wamagetsi, komanso kuyanjana kwamagetsi amagetsi amagetsi a LED.Mphamvu yabwino yoyendetsa iyenera kuganizira izi, chifukwa mphamvu yoyendetsa ili mu nyali yonse ya LED.Udindo ndi wofunikira monganso mtima wa munthu.Ntchito yayikulu ya dalaivala wa LED ndikusintha voteji ya AC kukhala magetsi amagetsi a DC nthawi zonse, ndipo nthawi yomweyo malizitsani kufananitsa ndi voteji ya LED komanso yapano.Ntchito ina ya dalaivala wa LED ndikupanga katundu wamakono wa LED kulamulidwa pamlingo wokonzedweratu motsogozedwa ndi zinthu zosiyanasiyana.

Pali zikhalidwe kuti chiwonetsero chamagetsi cha LED chizitulutsa kuwala.Mpweya wopita patsogolo umagwiritsidwa ntchito kumapeto onse a PN mphambano, kotero kuti PN mphambano yokha imapanga mlingo wa mphamvu (kwenikweni mndandanda wa milingo ya mphamvu), ndipo ma electron amalumphira pamtunda uwu wa mphamvu ndikupanga ma photons kuti atulutse kuwala.Chifukwa chake, voteji yomwe imagwiritsidwa ntchito pa mphambano ya PN ndiyofunika kuyendetsa LED kuti itulutse kuwala.Kuphatikiza apo, chifukwa ma LED ndi zida za semiconductor zomwe zimakhala ndi mawonekedwe osasinthasintha, zimafunikira kukhazikika ndikutetezedwa panthawi yofunsira, motero zimadzetsa lingaliro la "drive" ya LED.

Aliyense amene adalumikizana ndi ma LED amadziwa kuti mawonekedwe a volt-ampere akutsogolo a ma LED ndi otsetsereka kwambiri (mphamvu yakutsogolo ndi yaying'ono kwambiri), ndipo ndizovuta kwambiri kupereka mphamvu ku LED.Sizingatheke kuyendetsedwa mwachindunji ndi gwero lamagetsi ngati nyali wamba za incandescent.Kupanda kutero, magetsi Ndi kuwonjezeka pang'ono kwa kusinthasintha, zamakono zidzawonjezeka mpaka kuti LED idzawotchedwa.Kuti mukhazikitse momwe ma LED akugwirira ntchito ndikuwonetsetsa kuti ma LED azitha kugwira ntchito moyenera komanso modalirika, mabwalo osiyanasiyana amtundu wa LED atuluka.
