Dab tsi yog txoj hauv kev los txuas ntxiv txhim kho kev ua haujlwm ntawm cov teeb pom kev zoo fluorescent?
Dab tsi yog txoj hauv kev los txhim kho kev ua haujlwm ntawm cov teeb pom kev zoo fluorescent?
Feem ntau yog cov hauv qab no los xav txog
1. Teeb hlaws dai tseem ceeb heev. Tsuas yog siv cov hlaws dai zoo thiab raug nqi.
2. Thaum tshav kub kub dissipation, tswj tshav kub dissipation zoo, tshav kub dissipation cuam tshuam rau lub neej ntawm lub teeb hlaws
3. Lub zog siv hluav taws xob, muab lub zog zoo, ua haujlwm tau zoo, ua haujlwm ntev thiab ruaj khov
4. Lub teeb kis ntawm lub PC npog yuav tsum tsis tsuas yog xa lub teeb kom zoo, tab sis kuj zoo nkauj, tsis tuaj yeem pom lub teeb hlaws dai, thiab lwm yam.
Nws yog qhov tsim nyog los tshawb nrhiav txuas ntxiv thiab txhim kho hauv kev xyaum.
Lub zog siv hluav taws xob yuav tsum yog tam sim no: cov yam ntxwv ntawm LED cov khoom siv hluav taws xob txiav txim siab tias nws cuam tshuam loj heev los ntawm ib puag ncig. Piv txwv li, raws li qhov ntsuas kub hloov pauv, tam sim no ntawm LED nce ntxiv, thiab nce qhov hluav taws xob, qhov tam sim no ntawm LED kuj tseem yuav nce ntxiv. Kev ua haujlwm mus sij hawm ntev tshaj qhov ntsuas tam sim no yuav ua rau lub neej ua haujlwm luv ntawm LED. Thiab qhov tam sim no LED yog txhawm rau xyuas kom nws cov haujlwm tam sim no tseem tsis hloov pauv thaum ib puag ncig yam xws li ntsuas kub thiab hloov pauv.
2 Kev sib piv ntawm LED teeb lub teeb hluav taws xob thiab lub teeb hluav taws xob: qee cov neeg siv khoom tsim lub teeb teeb ua ntej, thiab tom qab ntawd saib rau lub hwj chim. Lawv pom tias nws nyuaj rau muaj lub zog tsim nyog, txawm tias tam sim no loj dhau, qhov hluav taws xob me me dhau (xws li kuv> 350mA, V< 40v);="" lossis="" qhov="" tam="" sim="" no="" ntau="" dhau="" yog="" tias="" qhov="" hluav="" taws="" xob="" siab="" dhau="" (xws="" li="">< 40ma,="" v=""> 180V), qhov tshwm sim yog kev tsim cua sov loj heev, ua haujlwm tau qis, lossis cov khoom siv hluav taws xob tsis txaus. Qhov tseeb, xaiv cov txheej txheem sib txuas ua ke tau zoo tshaj plaws, qhov hluav taws xob thiab qhov tam sim no siv rau txhua LED yog tib yam, tab sis cov khoom siv hluav taws xob tuaj yeem ua haujlwm tau zoo tshaj plaws. Txoj hauv kev zoo tshaj yog tham nrog cov chaw tsim khoom siv hluav taws xob ua ntej, thiab txiav nws.
3LED ua haujlwm tam sim no: Kev ntsuas ua haujlwm tam sim no ntawm cov dav dav LED yog 20 mA, thiab qee lub chaw tsim khoom siv nws thaum pib, thiab tsim qauv yog 20 mA. Qhov tseeb, kev ua haujlwm tam sim no tseem ceeb heev ntawm qhov tam sim no. Tom qab ntau qhov kev ntsuas sib piv, nws tau tsim los ua 16-18 mA yog qhov zoo tshaj. Tag nrho tam sim no ntawm N kev sib txuas sib txuas=17 * N
