LED tsav tsheb fais fab khoom siv thiab hloov cov khoom siv hluav taws xob sib txawv hauv kev tsim thiab kev ua haujlwm, feem ntau hauv kev ruaj ntseg ntawm cov zis tam sim no thiab qhov hluav taws xob. LED tsav tsheb fais fab khoom siv feem ntau muab cov zis tam sim no, thaum hloov cov khoom siv hluav taws xob muab qhov hluav taws xob tas li. Qhov no txhais tau hais tias LED tsav tsheb fais fab khoom siv tuaj yeem hloov mus rau qhov sib txawv ntawm cov khoom thauj (xws li LED chips), thaum hloov cov khoom siv hluav taws xob xav tau cov khoom tshwj xeeb kom ua haujlwm zoo.
Noj AC220V input voltage ua piv txwv, kev ua haujlwm ntawm LED tsav lub zog muaj xws li kev kho thiab lim cov kauj ruam los hloov AC voltage mus rau siab -voltage DC. Tom qab ntawd, tus tsav tsheb tam sim no tsis tu ncua IC (xws li HV9910) hloov pauv qhov siab -voltage DC mus rau qhov tso tawm tam sim no. Raws li LED chips tsis yog - cov khoom sib txuas, txawm tias qhov hloov pauv me ntsis hauv lawv qhov hluav taws xob tuaj yeem ua rau muaj kev hloov pauv tseem ceeb hauv qhov tam sim no ntws los ntawm lawv. Yog li ntawd, LED chips feem ntau siv cov tsav tam sim no los xyuas kom meej tias qhov tam sim no tseem nyob ruaj khov txawm tias muaj pes tsawg tus chips txuas nrog tus tsav tsheb.
Nyob rau hauv sib piv, ib tug switching fais fab mov nrog AC220V input voltage, tom qab rectification thiab filtering, siv ib tug voltage regulator IC los hloov lub siab -voltage DC mus rau hauv ib tug ruaj khov tso zis voltage. Txawm li cas los xij, vim tias qhov tso zis hluav taws xob ntawm qhov hloov hluav taws xob hloov pauv tsis tu ncua, thaum cov zis tam sim no sib txawv nrog cov khoom thauj, txuas ncaj qha mus rau LED nti yuav ua rau muaj ntau dhau tam sim no, ua rau cov nti. Yuav kom daws tau qhov teeb meem no, lub zog tshwj xeeb adapter lossis tus tsav tsheb tam sim no IC feem ntau xav tau los kho qhov tso zis hluav taws xob ntawm lub zog hloov pauv mus rau qhov tam sim no tsis tu ncua rau LED nti.
Hauv cov ntsiab lus, LED tsav tsheb fais fab khoom siv thiab cov khoom siv hluav taws xob hloov pauv muaj qhov tsim qauv sib txawv. LED tsav tsheb fais fab khoom siv tau zoo dua rau kev siv hluav taws xob LED chips, thaum hloov cov khoom siv hluav taws xob yuav tsum tau siv ua ke nrog lwm cov khoom siv kom ntseeg tau tias kev ua haujlwm zoo ntawm LED chips.
