Kev ua haujlwm ntawm LED teeb pom kev zoo thiab lub tuam txhab cov kws tshaj lij tsis txaus rau kev hloov pauv hluav taws xob, thiab cov khoom siv hluav taws xob ua haujlwm tau zoo, tab sis qee qhov kev ntsuam xyuas tseem ceeb thiab kev sib raug zoo ntawm electromagnetic tsis txaus, tseem muaj qhov tsis txaus ntseeg; Feem ntau ntawm cov khoom siv hluav taws xob LED Cov tuam txhab ua haujlwm tau hloov pauv los ntawm kev hloov pauv hluav taws xob los ua lub zog LED. Cov yam ntxwv thiab kev siv ntawm LED tsis txaus; Cov qauv tam sim no ntawm LEDs yuav luag tsis muaj, feem ntau ntawm lawv yog cov qauv siv rau kev siv hluav taws xob hloov hluav taws xob thiab hluav taws xob rectifiers; tam sim no feem ntau ntawm cov LEDs Cov khoom siv hluav taws xob tsis sib xws, yog li feem ntau ntawm lawv yog me me. Kev yuav khoom kom muaj nuj nqis me me, tus nqi siab, thiab cov khoom lag luam tsis sib npaug; kev ruaj ntseg ntawm LED fais fab mov: qhov teeb meem ntawm dav voltage input, siab kub muag thiab tsis kub ua hauj lwm, tshaj kub, overvoltage tiv thaiv, thiab lwm yam.

Tsis muaj leej twg; thawj zaug yog lub voj voog tag nrho ntawm lub voj voog tsav, tshwj xeeb tshaj yog cov khoom siv tseem ceeb, xws li: Capacitor nyob rau hauv lub voj voog kub, cuam tshuam rau lub voj voog ntawm lub hwj chim; nws yog tus tsav tsheb LED los tawm tsam kev hloov pauv ntau dua, tshwj xeeb tshaj yog thaum tsav tsheb siab zog LEDs, vim tias txhua yam raws li lub zog ntawm lub teeb tso zis, nws yog qhov tsawg heev rau cov cua sov dissipation. Lub zog siv hluav taws xob hloov hluav taws xob cuam tshuam rau kev ua haujlwm ntawm LED lub zog txuag cov nyhuv; qhov kev faib ua feem tam sim no ntawm cov nqi hluav taws xob tas li tam sim no hauv kev siv lub zog me me (1-5W) Ze rau 1/3, nws tau nyob ze rau tus nqi ntawm lub teeb, thiab kev lag luam nce qib tau cuam tshuam rau qee yam.
