LED backlighting yog nquag siv hauv kev tsim qauv tshiab. Cov kab hluav taws xob LED yog siv hauv ntau daim teb. Piv txwv li, LEDs yog siv nyob rau hauv kev kho kom zoo nkauj sab hauv ntawm thaj chaw thiab vaj tsev. Cov khw qhov rai kuj raug teeb pom kev zoo nrog LED teeb, thiab cov tsheb kuj siv cov strips LED. Tus nqi qis, kev coj ua thiab yooj yim kev teeb tsa tau ua rau LEDs dhau mus.

Cov Lus Qhia
Kauj ruam 1
Thaum pib, koj yuav tsum txiav txim siab ntawm thaj chaw teeb tsa ntawm cov hlua LED thiab laij nws lub sijhawm ntev. Nws yog qhov tseem ceeb kom nco ntsoov tias cov hlua LED tuaj yeem txiav ntawm ntau ntu (piv txwv li, SMD 3528 Q60 sawb tuaj yeem txiav txhua txhua 5 cm), yog li qhov no yuav tsum tau coj mus rau hauv kev xam thaum xam.
Kauj ruam 2
Cov kauj ruam tom ntej yog qhov kev xaiv ntawm qhov khoom fais fab. Lub zog txuas hluav taws xob yuav tsum nruj nrog cov lus tshaj tawm lub zog ntawm daim kab xev. Thaum xaiv cov block, nws yog qhov zoo tshaj plaws los sab laj nrog tus kws tshaj lij tshaj lij txhawm rau txhawm rau txhawm rau kom tsis yuam kev.
Kauj ruam 3
Tom qab txhua tus tivthaiv tau txais kev pabcuam, koj yuav tsum npaj lub ntsej muag rau kom haum cov kab xev. Lub vev xaib tau zoo yog degreased (piv txwv li, nrog cawv). Nws yog qhov zoo dua yog tias saum npoo yog qhov zoo (kom tsis txhob muaj kev puas tsuaj rau daim pob hluav taws xob kis kab xev). Yog hais tias daim kab xev yuav tsum tau ntsuas rau ntawm cov hlau lossis lwm yam txheej txheem saum npoo, kab xev yuav tsum muaj rwb thaiv tsev.
Kauj ruam 4
Yog tias cov ntaub nplaum tsis tas yuav txiav, tom qab ntawd koj tuaj yeem ua tiav tam sim ntawd nrog kev teeb tsa. Cov txheej txheem LED muaj ib qho nplaum lo rau ntawm nraub qaum. Nrog kev pab ntawm no cov nplaum lo, cov ntaub nplaum raug ntsia. Qhov tiv thaiv txheej txheem tshem tawm thiab daim kab xev yog nias tiv thaiv saum npoo.
Kauj ruam 5
Cov kauj ruam kawg yuav los txuas cov kab xev rau lub zog thiab cov tswj hwm, uas yog tsim los ntawm cov xaim los ntawm daim kab xev. Txhua cov hlau tau nws tus kheej rau ntawm cov kab khiav conductive, R, G, B thiab V +, thiab tau txuas nrog, ntsig txog, polarity mus rau 4 kev nkag ntawm lub maub los R, G, B, V +. 220V network nrog ob lub xaim rau L + thiab N- cov txuas. Tom ntej no, txuas rau "+" ntawm cov fais fab txuas mus rau "+" ntawm cov maub los, thiab "-" rau "-", feem. qhov polarity ntawm qhov hluav taws xob yuav tsum tsis meej pem - qhov no tuaj yeem ua rau cov khoom siv tsis ua haujlwm thiab puas tsuaj rau daim kab xev.
