Cov Txuj Ci Txuag Hluav Taws Xob rau Cov Zaub LED: Cov Txheej Txheem Static thiab Dynamic Ua Rau Lub Neej Yav Tom Ntej Ntsuab Dua

Nrog rau kev siv dav dav ntawm cov zaub LED hauv ntau qhov xwm txheej, lawv cov kev ua haujlwm txuag hluav taws xob tau dhau los ua qhov kev txhawj xeeb tseem ceeb rau cov neeg siv. Paub txog lawv qhov ci ntsa iab siab, xim ci ntsa iab, thiab cov duab zoo, cov zaub LED tau tshwm sim los ua cov thev naus laus zis ua thawj coj hauv cov kev daws teeb meem niaj hnub. Txawm li cas los xij, lawv cov kev ua haujlwm tas mus li xav tau cov thev naus laus zis txuag hluav taws xob zoo kom txo cov nqi ua haujlwm mus sij hawm ntev.

1. Yuav Ua Li Cas Cov Zaub LED Ua Tau Zoo Zog

Raws li cov qauv fais fab (P = Tam sim no I× Voltage U), txo qhov tam sim no lossis voltage thaum tswj qhov kaj tuaj yeem txuag hluav taws xob tau zoo. Tam sim no, cov thev naus laus zis txuag hluav taws xob ntawm LED zaub tau muab faib ua ob pawg: cov txheej txheem static thiab dynamic.

Cov thev naus laus zis txuag hluav taws xob zoo li qub ua tiav qhov sib piv txuag hluav taws xob ruaj khov los ntawm kev tsim kho vajtse. Piv txwv li, siv cov raj LED ci ntsa iab kom txo qhov tam sim no lossis txuas nrog cov khoom siv hluav taws xob txuag hluav taws xob kom txo kev siv hluav taws xob. Cov kev tshawb fawb qhia tau tias lub zog hloov pauv 4.5V tuaj yeem txuag hluav taws xob ntau dua 10% dua li lub zog hloov pauv 5V ib txwm muaj.

Cov thev naus laus zis txuag hluav taws xob dynamic ntse dua, kho qhov kev siv hluav taws xob raws li cov ntsiab lus tiag tiag. Qhov no suav nrog:

1. Hom Ntse Dub Screen: Tus tsav tsheb nkag mus rau hauv hom pw tsaug zog thaum tso saib cov ntsiab lus dub, tsuas yog muab hluav taws xob rau thaj chaw tsim nyog.

2. Kev Hloov Kho Qhov Ci: Tam sim no raug hloov kho raws li qhov ci ntawm qhov screen; cov duab tsaus dua siv hluav taws xob tsawg dua.

3. Kev Kho Kom Raws Li Xim: Thaum cov duab tsaus zuj zus, qhov tam sim no yuav txo qis raws li ntawd, thiab txuag hluav taws xob ntxiv.

Cov txiaj ntsig zoo ntawm cov thev naus laus zis txuag hluav taws xob

Los ntawm kev sib txuas cov txheej txheem zoo li qub thiab cov txheej txheem dynamic, cov zaub LED tuaj yeem ua tiav cov txiaj ntsig txuag hluav taws xob ntawm 30% -45%. Qhov no tsis yog tsuas yog txo cov kev siv hluav taws xob xwb tab sis kuj txo cov nqi ua haujlwm rau cov neeg siv.

Saib mus tom ntej, kev nce qib hauv cov thev naus laus zis chip yuav txuas ntxiv txhim kho kev siv hluav taws xob ntawm cov zaub LED, pab txhawb rau yav tom ntej uas ruaj khov dua thiab zoo rau ib puag ncig.
