Qhov no yog qhov yooj yim heev - tus ntsuas rau LED sawb rau koj kho TV.

Kuv muaj teeb meem me ntsis nrog kuv lub TV LED. Ib qho ntawm cov hlua LED tau tawm mus, thiab kuv lub vijtsam dub. Txog thaum kuv ua lub teeb nyem ncaj qha rau hauv lub vijtsam thiab pom ib daim duab kuv tsis paub tias qhov twg yog qhov tsis yog - cov LEDs tsis ua haujlwm.

Cia kuv thov txim ua ntej - Kuv tsis yog tus kws tsim khoom siv hluav taws xob, thiab kuv tuaj yeem ua qee qhov blunders raws txoj kev. Kuv zoo siab rau ib qho kev kho lossis lus pom los ntawm cov kws tsim txuj ci ntau dua!

Cov ntaub ntawv tsim nyog:

39V roj teeb

Ib tug resistor

Me ntsis ntawm cov xov hlau

Yeem / pab tau:

Ib daim ntawv qhia zaub mov

Gator clips

Bluetack

Kuv cov hlua LED khiav ntawm 27V. Rau 32 TV, kab ntawv feem ntau muaj 9 LEDs txhua, thiab txhua LED yog 3V thauj khoom, thiab lawv tau txuas nrog ua ke.

Yog tias koj txuas 3 9V roj teeb ua ntu zus, koj yuav muaj lub zog siv hluav taws xob ntau dua 27V.

Kuv siv bluetac kom tau txais cov xov hlau kom nyob hauv kev sib cuag nrog cov dav hlau.

LEDs tsis tuav cov dej ntws zoo heev, yog li koj yuav tsum tso lub resistor rau hauv koj lub Circuit Court.

Kuv tau siv lub khob cij rau qhov no, tab sis cov txheej txheem koj tuaj yeem xaim koj cov resistor hauv kab rau lub davhlau ya nyob twg ntawm koj lub roj teeb pob. Kuv siv 68k ohm resistor vim nws yog thawj qhov kuv pom dag nyob ib puag ncig. Kuv kuj pom me me LED xiav (tej zaum ntsuas ntawm 1.5V) uas kuv muab tso rau hauv Circuit Court. Qhov no yog txhawm rau ntsuas ib kab uas ua tsis tau luv, thiab tau ua, tab sis tsis pom kev.

Nrhiav cov dav hlau ntawm txhua kab hlua LED thiab xaim lub roj teeb pob rau lawv. Nco ntsoov, LEDs yog diodes thiab tsuas yog siv tam sim no hauv ib qho kev taw qhia, yog li yog ib txoj hlua tsis ua haujlwm, xyuas kom tseeb tias koj xaim nws rov qab ua ntej.

Yog tias kab txaij tsis pom kev, nws yuav tawg.
