Kev tsim ob-theem yog sib tw nrog cov khoom lag luam siab, kev sib tw hauv Circuit Court thiab cov nqi tsim khoom. Txawm li cas los xij, cov neeg tsav tsheb ntawm hom no muaj peev xwm xa mus rau nws qhov kev thauj khoom kom raug tswj hwm DC voltage uas muaj cov ripples me me thiab tuav cov kev hloov pauv loj hauv AC lub zog tuaj.

Nruam dimming ntawm LED vaj huam sib luag teeb feem ntau ua tiav siv qhov txo qis tam sim no (CCR) dimming, tseem hu ua analog dimming. CCR txoj kev kho lub teeb tso zis los ntawm kev sib txawv ntawm cov tsav tam sim no pub rau LEDs. Lub voj voog dimming feem ntau yog tswj los ntawm 0-10V raws tu qauv. 0-10V tswj cov tsav tsheb feem ntau muab dumming mus rau 10 feem pua. Rau cov ntawv thov uas xav tau CCT zoo ib yam dhau qhov kev dimming tag nrho, pulse-width modulation (PWM) yog ib txoj hauv kev siv tau. PWM tsav tsheb muab cov pulses digital ntawm qhov dav sib txawv kom dim lub LEDs.

Flicker

LED tsav tsheb yuav tsum tau tsim los tsis tsuas yog ua haujlwm nrog kev ua haujlwm siab, tab sis kuj tsim kom muaj qhov tsawg kawg nkaus ripples nyob rau hauv cov zis tam sim no nkag mus rau LED load. Residual ripple yog qhov ua rau lub teeb flicker ntawm qhov zaus ntawm ob zaug ntawm cov kab hluav taws xob zaus (xws li 120 Hz lossis 100 Hz). Kev raug flicker ntev ntev yuav ua rau tib neeg lub qhov muag, txo qhov pom kev ua haujlwm, thiab tseem ua rau muaj cov tsos mob xws li mob taub hau, migraines thiab qaug dab peg hauv qee cov neeg. Loj tam sim no ripple feem ntau tshwm sim nyob rau hauv cov zis uas tsim los ntawm tus nqi qis ib-theem tsav tsheb vim tsis tiav kev tsuj ntawm qhov hloov pauv waveform tom qab kho. Txawm tias muaj tseeb hais tias tus nqi feem ntau tshaj lub teeb zoo, lub teeb flicker yuav tsum nruj tswj, tshwj xeeb tshaj yog xav txog LED vaj huam sib luag teeb muaj ib tug lager emission nto uas yog feem ntau nyob rau hauv lub teb ntawm saib. Rau lub teeb pom kev zoo, tus nqi tam sim no yuav tsum raug txo kom tsawg (tsawg dua ± 10 feem pua). Thaum lub luminaire ua haujlwm ntawm 120 Hz zaus, qhov feem pua ​​​​ntawm flicker (flicker modulation) yuav tsum tsawg dua 10 feem pua, thiab nyiam dua tsawg dua 4 feem pua.

Qhov loj me thiab kev teeb tsa

Feem ntau ntug-lit LED vaj huam sib luag teeb tsim rau kev teeb tsa hauv qab nthab muaj qhov loj me ntawm 2 'x 2' lossis 600 x 600 mm. 2 'x 4' lossis 600 x 1200 mm yog lwm qhov loj me. Qhov tseeb luminaire loj me me me. LED vaj huam sib luag teeb tuaj nrog mounting kev xaiv rau kev koom ua ke mus rau T-grid qab nthab systems los yog rau kev txhim kho rau hauv drywall los yog plaster nrog accessory flange cov khoom. Cov low profile luminaires no kuj tuaj yeem ua rau saum npoo siv cov khoom siv khoom siv los yog tshem tawm siv aircraft cable mounts.
