Ib tug linear LED tsav tsheb yog ib tug linear regulator uas feem ntau muaj nyob rau hauv ntim integrated circuits (ICs) uas tsuas yog yuav tsum tau ib tug rectified voltage qhov chaw, piv txwv li, ib tug choj rectifier rau rectify ib alternating tam sim no (AC) voltage los tsim ib tug tsav tsheb voltage. Ua tsaug rau lawv qhov me me thiab tus nqi qis, cov kab hluav taws xob yooj yim tsav tsheb tau ua rau muaj kev txaus siab rau thaj chaw ntawm LED teeb pom kev zoo. Cov khoom siv hluav taws xob hloov pauv (SMPS) yuav raug teeb tsa kom ua haujlwm tau zoo dua li cov khoom siv hluav taws xob tawm. Txawm li cas los xij, SMPS tsim qhov loj me ntawm DC lub zog los ntawm kev hloov pauv ceev kom ua rau muaj suab nrov ntau, yog li ua rau muaj kev cuam tshuam, uas cuam tshuam rau cov khoom siv hluav taws xob uas nyob ib sab. Cov tsav tsheb tawm muaj cov ntsiab lus tsis tshua muaj zaus, yog li tshem tawm qhov yuav tsum tau muaj cov reactive (xws li, inductive thiab/los yog capacitive) input EMI / EMC lim ntsiab. Linear LED tsav tsheb siv tsis muaj electrolytic capacitor uas khaws lub zog txaus los tsav lub circuits thaum lub sij hawm lub sij hawm uas tsis muaj kab hluav taws xob hluav taws xob, thiab yog li txuas ntxiv lub neej ntawm LED tsav tsheb thiab tsis muaj teeb meem ntawm flicker. Nrog rau qhov tsawg dua suav, qhov me me, linear LED tsav tsheb pab txhawb tus nqi tsim hluav taws xob LED tsav tsheb thaum tshem tawm cov kev sib txuas tsis muaj zog (lub neej luv luv electrolytic capacitor) hauv cov saw thiab txo tag nrho cov nqi ntawm cov tswv cuab (TOC). LED lub teeb xyaw hauv tsav tsheb-on-board (DOB) tsim teeb tsa cov tsav tsheb ICs thiab LED modules uas txo cov qauv ntawm LED luminaires.
