Kazhinji kutaura, magetsi e LED anogona kungopatsanurwa muzvikamu zviviri: munhuLED diode chiedzamasosi kana LED diode mwenje masosi ane resistors. Mumashandisirwo, dzimwe nguva LED mwenje masosi akagadzirwa semodule ine DC-DC inoshandura, uye yakaoma mamodules akadaro haasi mukati mechikamu chehurukuro yechinyorwa ichi. Kana iyo LED mwenje sosi kana module iri yakaparadzana LED diode pachayo, yakajairika dimming nzira ndeyekugadzirisa amplitude yeKupinza kwe LED ikozvino. Naizvozvo, kusarudzwa kwesimba rekutyaira kwe LED kunofanirwa kureva hunhu uhu. Ma LED emwenje mitsetse anoshandiswa zvakanyanya seanopikisa ane LED diode akabatana munhevedzano, saka voltage haina kugadzikana. Naizvozvo, vashandisi vanogona kushandisa chero inotengeswa inowanika yemagetsi magetsi ekufambisa kutyairaLED mwenje mitsetse.

Iyo yakanakisa LED strip dimming mhinduro ndeye kushandisa inobuda pulse wide modulation PWM dimming basa kugadzirisa zvakajairika deadtravel dimming matambudziko. Iyo inobuda kupenya inotsamira pakutenderera kutenderera kweiyo dimming siginecha kuti iwane dimming shanduko inoderedza kupenya. Iwo akakosha ma paramita ekusarudza magetsi ekutyaira ari dimming ongororo uye kuwanda kwekubuda kwepulse wide modulation PWM. Iko kushoma kudzima kugona kunofanirwa kunge kwakadzikira se 0.1% kuwana 8-bit dimming resolution yekusangana neese LED light strip dimming application. Iyo inobuda pulse wide modulation PWM frequency inofanirwa kunge yakakwira sezvinobvira kudzivirira matambudziko ekupenya kwechiedza, Zvinoenderana neakakodzera tekinoroji mabhuku ekutsvagisa, zvinokurudzirwa kuve neiyo frequency yakakwira kupfuura 1.25kHz kuderedza inooneka ghost flicker paziso remunhu.
