Feem ntau hais lus, LED teeb pom kev tuaj yeem muab faib ua ob pawg: tus kheejLED diode teebqhov chaw los yog LED diode teeb qhov chaw nrog resistors. Hauv cov ntawv thov, qee zaum LED teeb pom kev zoo yog tsim los ua ib qho module uas muaj DC-DC converter, thiab cov qauv nyuaj no tsis nyob rau hauv qhov kev sib tham ntawm tsab xov xwm no. Yog hais tias lub teeb ci LED lossis module yog cais LED diode nws tus kheej, txoj kev dimming feem ntau yog kho qhov amplitude ntawm lubLED input tam sim no. Yog li ntawd, kev xaiv ntawm LED tsav lub zog yuav tsum xa mus rau tus yam ntxwv no. LED lub teeb strips tau dav siv los ua cov resistors nrog LED diodes txuas nrog hauv series, yog li qhov voltage kuj tseem ruaj khov. Yog li ntawd, cov neeg siv tuaj yeem siv cov khoom lag luam uas muaj cov khoom siv hluav taws xob tas li los tsavLED teeb strips.

Qhov zoo tshaj plaws LED sawb dimming kev daws teeb meem yog siv cov zis pulse dav modulation PWM dimming muaj nuj nqi los daws cov teeb meem uas muaj tshwm sim. Cov zis brightness cia siab rau lub voj voog ntawm lub teeb liab dimming kom ua tiav qhov kev hloov pauv uas txo qhov ci. Qhov tseem ceeb ntawm kev xaiv lub zog tsav tsheb yog qhov kev tsom xam dimming thiab zaus ntawm cov zis pulse width modulation PWM. Qhov tsawg kawg dimming muaj peev xwm yuav tsum tsawg li 0.1% kom ua tiav 8-ntsis dimming daws teeb meem kom tau raws li tag nrho cov LED teeb sawb dimming daim ntaub ntawv. Cov zis pulse width modulation PWM zaus yuav tsum siab npaum li qhov ua tau los tiv thaiv teeb meem flickering, Raws li cov ntaub ntawv tshawb fawb txog kev tshawb fawb, nws raug pom zoo kom muaj zaus tsawg dua 1.25kHz kom txo tau pom dab flicker rau tib neeg lub qhov muag.
