Nws yog ib qho tshwm sim heev uas LED teeb tau dimmer ntau dua lawv siv.Raws li qhov tshwm sim, muaj peb qhov laj thawj vim li cas LED teeb tuaj yeem dimmed.

Tsav tsis ua haujlwm.

LED teeb hlaws yuav tsum muaj nyob rau hauv DC tsis tshua muaj hluav taws xob (qis dua 20V) ua haujlwm, tab sis peb lub ntsiab tseem ceeb yog AC high voltage (AC 220V).Cov hluav taws xob xav tau los tig lub zog hluav taws xob mus rau hauv lub teeb hlaws yuav tsum muaj cov cuab yeej hu ua "LED qhov tam sim no tsav lub zog hluav taws xob".

Kev hais lus theoretical, tsuav yog qhov tsis sib xws ntawm tus tsav tsheb thiab cov hlaws board sib tw, tuaj yeem txuas ntxiv rau lub zog, siv ib txwm siv.Sab hauv ntawm tus tsav tsheb yog qhov nyuaj dua.Qhov tsis ua haujlwm ntawm ib qho khoom siv (xws li capacitor, rectifier, thiab lwm yam) tuaj yeem ua rau qhov kev hloov pauv ntawm cov zis hluav taws xob, uas yuav ua rau lub teeb dimming.

LED burnout.

LED nws tus kheej yog tsim los ntawm kev sib txuas ntawm lub teeb hlaws, yog tias ib qho lossis ib feem ntawm lub teeb tsis ci, nws yuav tsum ua kom tag nrho lub teeb tsaus.Lub teeb hlaws feem ntau txuas nrog hauv koob thiab tom qab ntawd nyob rau hauv qhov sib npaug - yog li lub teeb hlaws tau hlawv, nws muaj peev xwm ua rau ntau lub teeb hlaws tsis ci.

Muaj qhov pom tseeb dub me ntsis ntawm qhov chaw ntawm lub teeb ci hlaws.Nrhiav nws thiab txuas nws nrog ib lub xaim ntawm nws sab nraub qaum kom luv-circuit nws.Los yog hloov lub teeb hlaws tshiab, tuaj yeem daws qhov teeb meem.

LED qee zaus hlawv ib qho, tej zaum los ntawm kev sib tsoo.Yog tias koj hlawv ntau zaus, koj yuav tsum xav txog cov teeb meem tsav tsheb - lwm qhov tshwm sim ntawm kev tsav tsheb tsis ua haujlwm yog qhov kub hnyiab ntawm cov hlaws.

LED fading.

Lub teeb lwj yog thaum lub luminosity ntawm lub teeb yuav tsawg dua thiab tsis kaj siab - ib qho mob uas tau tshaj tawm hauv cov teeb pom kev zoo thiab cov teeb fluorescent.

LED teeb tsis tuaj yeem zam lub teeb lwj, tab sis nws lub teeb tawg nrawm kuj qeeb, feem ntau nrog lub qhov muag liab qab yog qhov nyuaj rau pom qhov hloov.Tab sis nws tsis suav nrog qhov tsis zoo ntawm LED, lossis lub teeb pom kev tsis zoo ntawm cov hlaws dai, los yog vim tsis muaj cua sov dissipation thiab lwm yam hom phiaj, ua rau lub teeb ci LED poob nrawm dua.
