Ib txoj hauv kev zoo los ntsuas cov khoom siv hluav taws xob yog siv lub multimeter. Teem lub multimeter los nyeem DC voltage thiab txuas cov probes mus rau lub hwj huam mov cov zis nyob ntawm tej. Yog tias qhov hluav taws xob qis dua li qhov tau teev tseg ntawm LED sawb lub teeb pob, nws yog lub sijhawm los hloov cov khoom siv hluav taws xob.

Subheading 3: Tshawb xyuas Cov Hluav Taws Xob

Yog tias koj lub teeb ci LED yuav tsis tig, xyuas cov xaim kom muaj kev sib txuas xoob lossis puas. Siv lub ntsuas hluav taws xob los xyuas kom meej tias tsis muaj qhov tam sim no ntws los ntawm cov hlau ua ntej koj pib tshuaj xyuas.

Pib los ntawm kev tshuaj xyuas cov xov hlau uas txuas rau LED sawb lub teeb rau tus maub los. Qee zaum cov xaim tuaj yeem xoob, tiv thaiv tus maub los ntawm kev xa cov teeb liab mus rau LED sawb teeb. Tshawb xyuas cov kev txiav lossis nicks ntawm cov xov hlau uas tuaj yeem cuam tshuam cov teeb liab.

Yog tias cov xov hlau zoo li qub, txav mus rau kev tshuaj xyuas cov pins uas txuas rau LED sawb teeb rau lub zog hluav taws xob. Qee zaum, cov pins ntawm lub strips yuav raug puas tsuaj, tiv thaiv lawv kom tsis txhob muaj hluav taws xob los ntawm lub hwj chim mov. Yog tias koj pom tias muaj kev puas tsuaj, hloov cov pins thiab sim tig lub teeb sawb dua.

Subheading 4: Hloov Faulty LEDs

LED sawb teeb muaj cov saw hlau ntawm ib tus neeg LED teeb uas ua rau tag nrho cov teeb pom kev zoo. Qhov tsis ua haujlwm ntawm ib lub teeb ci LED tuaj yeem ua rau tag nrho lub teeb ci ntsa iab tsis ua rau lub teeb pom kev zoo. Yog tias LED sawb lub teeb tsis tsim nws lub teeb ci, thawj kauj ruam los nrhiav qhov teeb meem LED yog los ntawm kev faib cov LED sawb teeb rau hauv cov ntu me. Tom qab ntawd, sim txhua ntu ntawm tus kheej.

Txhawm rau ua qhov no, koj yuav tsum muaj 12V lub zog hluav taws xob thiab lub zog tiv thaiv. Txuas koj lub teeb ci LED mus rau lub zog los ntawm 100-ohm resistor. Yog tias lub teeb ci LED hauv ntu ntawd tsis qhib, nws yog qhov yuam kev uas xav tau hloov pauv.

Txhawm rau hloov qhov teeb meem LED, koj yuav xav tau ntau yam cuab yeej, suav nrog ob lub txiab, ob lub pliers, thiab cov khoom siv soldering. Txiav lub teeb sawb ntawm qhov taw tes ntawm qhov teeb meem LED thiab tshem tawm cov teeb meem LED siv cov pliers. Tom qab ntawd, solder lub hloov LED lub teeb rau ntawm cov hlau cim. Txhawm rau tuav lub teeb ci LED nyob rau hauv qhov chaw, npog nws nrog cua sov shrink tubing.

Subheading 5: Kho Frayed Wires

LED sawb teeb muaj qhov cuam tshuam rau kev puas tsuaj - lub cev puas tsuaj, ntau dua - thiab ib qho teeb meem uas lawv ntsib yog frayed nyob ntawm tej. Cov kab hluav taws xob tawg lossis tawg tuaj yeem ua rau luv luv, ua rau nws ua tsis tau rau LED sawb teeb ua haujlwm.

Txhawm rau txhim kho cov xaim frayed, ua ntej, tua hluav taws xob LED sawb lub teeb thiab txiav tawm ntawm lub hwj chim mov. Siv ib rab riam ntse los yog txiab, txiav tawm qhov puas ntawm cov hlau. Tom qab ntawd, strip ib ncig ntawm 1 cm ntawm rwb thaiv tsev los ntawm qhov kawg ntawm ob qho tib si sib cais cov hlau. Tom qab ntawd, ntswj cov hlau xaus ua ke thiab npog lawv nrog hluav taws xob daim kab xev los yog npog lawv nrog lub tshav kub shrink tubing sawb siv rab phom kub.

Subheading 6: Xaus

LED sawb teeb yog kev nqis peev hauv kev tsim lub teeb pom kev zoo lossis qhov chaw nyob ib puag ncig. Txawm li cas los xij, zoo li txhua lub teeb lossis cable, lawv yuav tsim teeb meem thaum lub sijhawm thiab xav tau kev saib xyuas thiab kho. Cov lus qhia saum toj no yuav pab kho cov teeb meem LED sawb feem ntau, ua rau koj txaus siab rau qhov pom kev zoo rau xyoo.
