Nws yog ib qho xwm txheej uas feem ntau tshwm sim uas cov teeb LED yuav tsaus zuj zus thaum siv ntau dua. Hauv kev xaus, muaj peb qho laj thawj uas ua rau cov teeb LED tuaj yeem tsaus zuj zus.

Kev tsav tsheb tsis ua haujlwm.

Cov kev xav tau ntawm cov teeb LED hauv DC qhov hluav taws xob qis (qis dua 20V) ua haujlwm, tab sis peb cov mains ib txwm yog AC qhov hluav taws xob siab (AC 220V). Cov hluav taws xob xav tau los hloov lub zog tseem ceeb mus rau hauv lub teeb bead xav tau lub cuab yeej hu ua "LED constant current drive power supply".

Hauv kev xav, tsuav yog cov kev teeb tsa ntawm tus tsav tsheb thiab lub rooj tsavxwm sib phim, tuaj yeem txuas ntxiv mus rau lub zog, siv li qub. Sab hauv ntawm tus tsav tsheb nyuaj dua. Kev ua tsis tiav ntawm txhua yam khoom siv (xws li capacitor, rectifier, thiab lwm yam) yuav ua rau qhov hloov pauv ntawm qhov hluav taws xob tso zis, uas yuav ua rau lub teeb tsaus ntuj.

LED hlawv.

LED nws tus kheej yog ua los ntawm kev sib xyaw ua ke ntawm cov hlaws teeb, yog tias ib lossis ib feem ntawm lub teeb tsis ci, nws yuav ua rau tag nrho lub teeb tsaus ntuj. Cov hlaws teeb feem ntau txuas ua ke ua ke thiab tom qab ntawd ua ke ua ke - yog li cov hlaws teeb hlawv, nws ua tau kom muaj ntau cov hlaws teeb tsis ci.

Muaj cov xim dub pom tseeb ntawm qhov chaw ntawm lub teeb uas kub hnyiab. Nrhiav nws thiab txuas nws nrog ib txoj hlua ntawm nws nraub qaum kom luv luv. Los yog hloov lub teeb tshiab, tuaj yeem daws qhov teeb meem.

Qee zaum LED hlawv ib qho, tej zaum yog vim tsis tau xav txog. Yog tias koj hlawv ntau zaus, koj yuav tsum xav txog cov teeb meem ntawm tus tsav tsheb - lwm qhov qhia txog kev ua tsis tiav ntawm tus tsav tsheb yog qhov hlawv ntawm lub hlaws.

LED fading.

Lub teeb lwj yog thaum lub teeb ci ntsa iab tsawg zuj zus - ib qho mob uas pom tseeb dua hauv cov teeb roj incandescent thiab fluorescent.

Cov teeb LED tsis tuaj yeem zam kev lwj ntawm lub teeb, tab sis nws qhov kev lwj ntawm lub teeb qeeb heev, feem ntau nrog lub qhov muag liab qab nws nyuaj rau pom qhov kev hloov pauv. Tab sis nws tsis tshem tawm cov LED qis dua, lossis cov laug cam teeb tsis zoo, lossis vim tsis muaj cua sov thiab lwm yam tseem ceeb, ua rau qhov kev poob ntawm lub teeb LED sai dua.
