LED yemagetsi kuratidza imhando yeazvino kudzora mudziyo, mutyairi we LED isimba rekutyaira re LED, kureva kuti, mudziyo wedunhu unoshandura simba re AC kuita rinogara riripo kana rinogara riri voltage DC simba.Kusiyana neakajairwa incandescent bulbs, LED zvemagetsi zviratidziro zvinogona kubatanidzwa zvakananga ku220V AC mains.Ma LED ane zvinenge zvakaoma zvinoda simba rekutyaira, uye simba rawo rekushanda rinowanzoita 2 ~ 3V DC voltage, uye dunhu rakaoma rekushandura rinofanira kugadzirwa.Mwenje dze LED dzezvinangwa zvakasiyana dzinofanirwa kuve dzakashongedzerwa neakasiyana emagetsi adapter.

Zvishandiso zveLED zvine zvakakwirira kwazvo zvinodiwa pakushandurwa kwesimba, simba rinoshanda, kurongeka kwazvino, hupenyu hwesimba, uye kuenderana kwemagetsi kweiyo LED drive simba.Simba rekutyaira rakanaka rinofanira kutora zvinhu izvi mukufunga, nekuti simba rekutyaira riri mumwenje wese we LED.Basa rakakosha semoyo wemunhu.Basa guru remutyairi we LED ndere kushandura iyo AC voltage kuita inogara iripo DC magetsi emagetsi, uye panguva imwe chete kupedzisa kuenderana neiyo LED voltage uye ikozvino.Rimwe basa remutyairi we LED nderekuita kuti mutoro wazvino we LED udzorerwe padanho rakagara rakagadzirwa pasi pesimba rezvinhu zvakasiyana.

Pane mamiriro ekuti LED yemagetsi kuratidza kubudisa chiedza.Voltage yekumberi inoiswa kumigumo yese yePN junction, zvekuti PN junction pachayo igadzire mwero wesimba (chaizvoizvo nhevedzano yemazinga esimba), uye maerekitironi anosvetuka padanho resimba iri uye anogadzira mafotoni kuti abudise chiedza.Naizvozvo, iwo magetsi akaiswa pamhiri pePN junction anodiwa kutyaira iyo LED kuti ibudise mwenje.Uyezve, nekuti ma LED ane hunhu-sensitive semiconductor zvishandiso zvine maitiro asina kunaka etembiricha, anofanirwa kudzikamiswa uye kuchengetedzwa panguva yekunyorera, nekudaro zvichipa pfungwa ye LED "drive".

Chero ani anga achibatana ne LEDs anoziva kuti kumberi volt-ampere maitiro e LEDs akanyanya kukwira (yemberi ine simba voltage idiki kwazvo), uye zvakanyanya kuoma kupa simba kune LED.Iyo haigone kuve yakananga simba nemagetsi sosi seyakajairwa incandescent marambi.Zvikasadaro, iyo voltage Nekuwedzera kudiki kwekuchinja, ikozvino ichawedzera kusvika pakuti iyo LED ichapiswa kunze.Kuti ugadzikane kushanda kweiyo LED uye kuve nechokwadi chekuti LED inogona kushanda zvakajairwa uye yakavimbika, akasiyana ma LED drive maseketi abuda.
