Cov tsav tsheb sib cais LED thiab cov tsav tsheb tsis sib cais yog ob hom LED tsav tsheb uas siv los ua lub zog LED teeb. Qhov sib txawv tseem ceeb ntawm ob tus tsav tsheb no yog cov tsav tsheb sib cais LED muab hluav taws xob sib cais ntawm cov tswv yim thiab cov zis, thaum cov tsav tsheb tsis sib cais LED tsis ua.
Cov neeg tsav tsheb sib cais LED siv lub tshuab hloov hluav taws xob los muab kev sib cais hluav taws xob, uas ua kom ntseeg tau tias cov khoom siv hluav taws xob thiab cov khoom siv sib cais tag nrho thiab tsis sib koom ua ke hauv av hluav taws xob. Qhov no muab kev nyab xeeb ntxiv thiab tiv thaiv hluav taws xob poob siab thiab tuaj yeem txo qhov cuam tshuam ntawm electromagnetic. Cov tsav tsheb sib cais LED feem ntau kim dua li cov tsav tsheb tsis sib cais vim yog cov khoom siv ntxiv thiab cov txheej txheem tsim khoom yuav tsum tau ua.
Cov tsav tsheb tsis sib cais LED tsis muab hluav taws xob cais tawm thiab muaj cov tswv yim thiab cov khoom siv txuas nrog tib lub hauv av hluav taws xob. Lawv feem ntau tsis tshua kim thiab yooj yim rau kev tsim thiab tsim dua li cov tsav tsheb sib cais LED. Txawm li cas los xij, cov tsav tsheb tsis sib cais LED yuav tsis ua raws li qee qhov kev nyab xeeb lossis cov qauv kev tswj hwm hauv qee qhov kev siv vim tsis muaj hluav taws xob cais tawm.
Thaum xaiv tus tsav tsheb LED, nws yog ib qho tseem ceeb uas yuav tsum xav txog kev nyab xeeb thiab kev tswj hwm ntawm daim ntawv thov, nrog rau cov nqi thiab kev nyuaj ntawm tus tsav tsheb. Cov tsav tsheb sib cais LED feem ntau nyiam nyob rau hauv cov ntawv thov uas muaj kev nyab xeeb thiab kev tiv thaiv hluav taws xob poob siab yog ib qho kev txhawj xeeb, thaum cov tsav tsheb tsis raug rho tawm yog tsim nyog rau cov ntawv thov tsawg dua qhov uas tus nqi thiab qhov yooj yim yog qhov tseem ceeb.
Tsis tas li ntawd, Isolated coj tsav tsheb tso zis voltage yog 30 mus rau 40V DC, Tsis yog tus neeg tsav tsheb cais tawm qhov hluav taws xob yog 50 txog 80 V DC, yog li nws kuj ua rau isoaled coj tsav tsheb muaj kev nyab xeeb rau tib neeg.
