Kev sib txuas zoo ntawm LED sawb yuav tsum ua raws li cov lus qhia tshwj xeeb uas yuav muab hauv qab no. Ua raws li lawv, qhov tsim teeb pom kev zoo nrog koj tus kheej txhais tes yuav tsum nyob ntev li ntev tau.

Yog li, ua ntej txuas ncaj qha mus rau kev teeb tsa ntawm daim kab xev, thawj kauj ruam yog ntsuas qhov ntev ntawm ntu uas nws yuav raug teeb tsa. Nws yog ib qho tseem ceeb. Tom qab tag nrho, txhua qhov ntawm LED strips tsuas yog muab faib ua tej yam tsawg kawg nkaus (txiav piv). Qee qhov ntawm lawv tuaj yeem raug txiav tawm ntawm feem ntau kom tsuas yog peb lub LEDs nyob, thiab lwm hom kom ob lossis plaub seem, thiab lwm yam. (nws tag nrho yog nyob ntawm hom khoom).

Tau kawg, tau txiav txim siab tsuas yog qhov ntev yuav tsum tau, nws tseem tsis tau txuas rau LED sawb. Qhov thib ob, kuj tseem ceeb heev rau theem yog qhov kev xaiv ntawm lub zog tsim nyog tshaj plaws nyob rau hauv cov nqe lus ntawm tsis. Tom qab tag nrho, qhov ntau dhau los yog tsis txaus ntawm cov tsis xws li kev khiav hauj lwm voltage thiab lub zog tshwj xeeb ntawm LED sawb tuaj yeem ua rau nws tawm tam sim lossis ntxov ntxov.tawm ntawm kev pabcuam. Yog tias koj txiav txim siab siv cov kab xev xim (RGB), tom qab ntawd ntxiv rau cov khoom siv hluav taws xob, koj kuj yuav tsum tau yuav lub microcontroller uas xav tau lub hwj chim zoo. Tom qab kev yuav tag nrho cov tsim nyog, thiab qhov tseem ceeb tshaj plaws, cov cuab yeej tsim nyog, kev teeb tsa thiab kev sib txuas ntawm LED sawb tuaj yeem pib.

Muaj ntau txoj hauv kev los siv hom kev kho kom zoo nkauj no. Tab sis feem ntau siv LED sawb los teeb lub qab nthab. Txawm li cas los xij, ib qho yog qhov tseeb: txhua qhov chaw nws tau teeb tsa, cov cai ntawm kev teeb tsa yog tib yam hauv txhua kis. Hauv qab no yog qee cov lus qhia rau qhov no.

Feem ntau LED strips muaj txheej nplaum uas lawv txuas nrog. Thiab txij li nws paub tias cov kua nplaum tsis zam cov plua plav thiab roj, qhov chaw yuav tsum tau ua tib zoo ntxuav, tshwj tsis yog, ntawm chav kawm, nws tsis muaj paug. Qhov no yog ua los ntawm tes. Qhov chaw uas daim kab xev yuav tsum tau muab so nrog cawv los yog tej yam hnyav - qhov no yuav tshem tawm tag nrho cov roj.

Tam sim no nws tsuas yog tshem tawm cov txheej txheem tiv thaiv sab nraum qab ntawm daim kab xev thiab muab tso rau saum npoo (tsis txhob nias lub zog ntawm lub cuab yeej, txhua yam ua tiav nrog lub teeb txav). Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias koj tsis tuaj yeem khoov daim kab xev ntau dhau - qhov no tuaj yeem ua rau cov neeg raug puas tsuaj (qhov tsawg kawg yog khoov vojvoog yog 20 hli), thiab thaum txiav nws, koj yuav tsum siv txiab. Nws kuj tseem ceeb heev kom tsis txhob puas cov ntsiab lus soldering. Thiab yog hais tias koj xav tau solder ob daim nyias nyias, ces koj yuav tsum tau muab ib tug soldering hlau rau tej qhov chaw. Qhov kub yuav tsum tsis txhob siab tshaj 260 degrees.

Tam sim no koj tuaj yeem txuas lub LED sawb rau lub zog hluav taws xob. Nws yog ib qho tseem ceeb kom tsis txhob sib cuag nrog dej thiab lwm yam khoom siv hluav taws xob.

Summarizing, peb tuaj yeem muab cov lus qhia ntxiv rau kev tuav LED strips:

  • - Cov hlua hloov tau yuav tsum tsis txhob khoov vim tsis muaj laj thawj.
  • - Tsis txhob tso kev sib cuag tawg.
  • - Saib qhov polarity ntawm hluav taws xob thaum txuas daim kab xev rau lub zog.
  • - Nws yog ib qho tseem ceeb uas yuav tsum siv cov khoom siv fais fab uas tsim nyog tshaj plaws.
  • - Thaum daim kab xev yog mounted ntawm ib tug conductive nto, lub cheeb tsam yuav tsum tau ua ntej insulated.
