Cov kab hluav taws xob LED yog siv los taws tawm hauv cov khoom sab hauv. Vim tias lawv cov tuab me me, lawv tuaj yeem nyob rau qhov twg lwm cov khoom siv hluav taws xob tsis tuaj yeem, thiab vim lawv qhov ntev ntau, lawv muab cov teeb pom kev zoo sib xws.
Cov Lus Qhia

Txij li cov hlua LED tuaj yeem tsuas txiav raws cov kab tsim tshwj xeeb nyob ntawm ib metres sib nrug, tsim cov rooj tog zaum yuav tsum taws ua ntej kom qhov ntev ntawm thaj chaw taws teeb yog ntau yam ntawm cov nqi no. Yog tias qhov no tsis tuaj yeem (piv txwv li, qhov khoom yuav tsum tau hais qhia twb muaj lawm), koj tuaj yeem nthuav txoj kab ib nrab, tawm ntawm cov chaw tsaus me me raws nws cov npoo.

Nws raug nquahu kom xaiv ib qho chaw rau gluing cov kab xev thiaj li ua rau LEDs lawv tus kheej tsis pom, tab sis tsuas yog lawv cov teeb ci los ntawm qhov chaw ci pom kev pom. Xaiv cov kab xev nws tus kheej nyob ntawm cov xwm txheej teeb tsa: nws tuaj yeem muaj nrog lossis tsis muaj cov nplaum lo, thiab nws kuj tuaj yeem tiv thaiv dej los yog qhib. Yog tias tsis muaj txheej nplaum nplaum, koj yuav tsum siv cov nplaum uas haum rau cov khoom siv kab xev thiab cov khoom uas koj xav tso rau.

Xam cov hluav taws xob tam sim no rau qhov kev fais fab yuav tsum tau ntsuas. Txhawm rau ua qhov no, nce lub zog ceev ntawm daim kab xev (hauv watts hauv ib meter) los ntawm nws tag nrho qhov ntev (hauv meters). Faib cov txiaj ntsig, uas yuav nyob hauv watts, los ntawm kev khiav hauj lwm voltage, yog li nrhiav qhov tam sim no hauv amperes. Xaiv lub zog hluav taws xob nrog cov npoo ntawm tsawg kawg 1, 5. Nws yuav tsum muab kev sib cais los ntawm lub network, thiab nws qhov tso tawm hluav taws xob yuav tsum sib npaug lossis tsawg dua li kev ua haujlwm voltage ntawm cov kab xev. Yuav tsum tsis muaj qhov tawm tsam - lawv muaj nyob hauv kab xev.

Koj tuaj yeem muab lub zog rau cov kab xev los ntawm ob sab, soj ntsuam qhov polarity. Nrog rau kev noj khoom siv tam sim no ntau dua ib ampere, nws yuav tsum tau txiav mus rau cov ntu sib cais thiab muab rau txhua qhov hluav taws xob nrog cov xov hluav taws xob txhawm rau kom tsis txhob muaj qhov kub ntxhov dhau ntawm cov ntawv luam conductors. Ua qhov sib txuas los ntawm soldering, thiab yog tias daim kab xev yog dej tsis txaus thiab ua haujlwm nyob rau hauv cov kev tsim nyog, muab cov ntsiab lus soldering, ntxiv rau txhua qhov, tsis muaj qhov tshwj xeeb, cov txiav ntu nrog cov ntaub hu. Tsis txhob cia lub voj voog luv, thiab muab lub qhov chaw nws tus kheej nyob sab hauv.

Koj tuaj yeem muab lub zog rau ntu los ntawm ib sab, thiab tshem tawm los ntawm qhov rov qab, thiab tom qab ntawd thov siv, soj ntsuam qhov polarity, mus rau lwm ntu ntawm daim kab xev. Tab sis tsis txhob ua phem rau qhov no - saib xyuas txoj cai saum toj no, raws li qhov uas, los ntawm cov kab xev tam sim no ntawm daim kab xev, qhov tam sim no ntau dua li ib ampere yuav tsum tsis txhob ntws.
Kauj Ruam 6
Qhov teeb meem tam sim ntawd poob hauv qhov ci ci ntawm tag nrho cov kab xev qhia qhov tsis ua haujlwm tsis yog ntawm LED, tab sis ntawm cov khoom siv fais fab. Nws txoj kev kho kom zoo (feem ntau hloov chaw ntawm electrolytic capacitors yog qhov yuav tsum tau) tso siab rau tsuas yog cov neeg uas muaj kev paub thiab kev paub zoo.
