Thaum ua haujlwm ntawm cov haujlwm uas sivsiab - zog LED strips, tej zaum koj yuav tau pom lossis hnov tias qhov hluav taws xob poob tuaj yeem cuam tshuam cov strips. Lub zog poob hauv LED sawb yog dab tsi? Daim ntawv no qhia koj tias dab tsi ua rau nws thiab yuav ua li cas kom tsis txhob tshwm sim.
Yog vim li cas lub hwj chim poob nyob rau hauv ib tug LED sawb tshwm sim
Txawm hais tias nws yuav tsis zoo li nws, ib qho LED sawb (cia peb siv 12V rau qhov kev hais lus no) yog ib pawg ntawm peb LEDs uas txuas nrog tib lub sijhawm.
Yog li, txawm tias txhua pab pawg ntawm peb LEDs yog npaj los ua haujlwm nrog 12V, LED pawg uas nyob deb ntawm lub zog hluav taws xob feem ntau yuav muab tsawg dua 12V, ua rau lub teeb tso zis ntau dua. Vim li cas qhov no tshwm sim?
Thawj qhov yog vim li cas cov teeb pom kev deb ntawm lub hwj chim yuav tsum tau lub zog taug kev raws txoj kab ntev tooj liab kom ncav cuag lawv.
Raws li qhov kev ncua deb ntawm cov kab tooj liab loj hlob, yog li lawv cov kev tiv thaiv sab hauv. Qhov no txhais tau hais tias lub zog tsawg dua tuaj yeem ncav cuag LEDs uas nyob deb ntawm lub zog hluav taws xob.
Thaum koj txav cov kab tooj liab los ze zog rau lub zog, lawv yuav tsum nqa tag nrho cov tam sim no siv los ntawm LEDs txuas ntxiv mus. Qhov no yog qhov laj thawj thib ob.
Ib qho piv txwv yog ib qhoLED sawbuas muaj peev xwm lis 5 Amps ib kab (5 meters). Yuav luag tag nrho cov 5 Amps yuav dhau los ntawm thawj feem ntawm lub sawb. Plaub amps tseem yuav dhau los ntawm qhov taw tes no txog ib meter hauv. Tsuas yog 2 Amp yuav dhau mus ntawm 3 meters hauv.
Vim li cas qhov no tseem ceeb? Tooj liab muaj kev tiv thaiv ntau dua li nws qhov ceev tam sim no nce. Yog li 5 Amps thaum pib ntawm LED sawb tej zaum yuav ntau dhau rau cov tooj liab ua rau kev daws teeb meem. Qhov no yuav ntxiv ntau qhov hluav taws xob tiv thaiv tam sim ntawd, ua rau qhov hluav taws xob rau tag nrho cov LEDs ntxiv rau hauv kab txawm qis dua.
Nco ntsoov tias qhov no kuj mus rau cov plugs thiab tag nrho cov xov hlau uas txuas lub hwj huam mov rau LED sawb. Cov kab sib txuas yuav tsum muaj qhov loj ntawm cov hlau. Yog tias lawv tsis ua, koj tuaj yeem poob lub zog ua ntej cov ntaub ntawv txawm mus rau LED sawb!
Raws li peb pom thaum peb saib ntawm qhov voltage ntawm LED strips, txawm tias ib qho me me poob hauv qhov hluav taws xob tuaj yeem ua rau lawv tsis tshua pom kev.
Tej yam uas tuaj yeem ua rau cov teebmeem ntawm LED sawb lub zog poob qis dua
Tam sim no kos thiab tooj liab thickness yog cov tseem ceeb uas txiav txim siab npaum li cas voltage poob yuav tshwm sim.
Ntau npaum li cas tam sim no LED sawb kos yog qhov tseem ceeb tshaj plaws. Qhov no tuaj yeem hloov tau los ntawm qhov ntev ntawm cov sawb siv los yog nws tau tsim nyob rau hauv thawj qhov chaw (piv txwv li, hauv watts ib meter). Koj tsuas tuaj yeem siv li 2 amps tam sim no nrog lub siab - lub zog LED sawb yog tias koj tsuas yog siv 1-meter thaj.
Feem ntau, txoj kab uas hla tooj liab yog ntsuas hauv ooj. Qhov no yog cov tooj liab uas xav tau los npog qhov chaw ntawm 1 square feet. Cov hluav taws xob ntau tuaj yeem ntws los ntawm cov hlau yog tias cov tooj liab loj dua. Peb xav kom 2.0 oz, thiab 3.0 oz yog qhov zoo dua rau LED strips nrog ntau lub zog.
Puas yog qhov poob hauv lub zog ntawm LED sawb tsis zoo?
Thaum voltage poob hauv ib qhoLED sawb, nws txhais tau hais tias cov LEDs tau txais lub zog tsawg dua li qhov tau npaj tseg. Qhov no feem ntau tsis cuam tshuam li cas cov LEDs ua haujlwm zoo.
Tab sis qhov poob ntawm qhov hluav taws xob feem ntau txhais tau tias koj poob lub zog vim hluav taws xob tsis kam, uas ua rau muaj cua sov ntau. Qhov no tuaj yeem yog teeb meem yog tias koj cov hlua LED tau muab tso rau hauv lossis ze rau cov ntaub ntawv uas tsis nyiam cua sov. Nws yog qhov ua tau rau qhov hluav taws xob poob siab dhau vim tias ob qho tib si 3M nplaum rov qab thiab cov LEDs yog me ntsis rhiab rau cua sov.
Kuv yuav ua li cas kom tsis txhob poob ntawm kuv cov LED strips?
Yog tias koj paub vim li cas LED strip voltage poob, koj tuaj yeem nres lawv ua ntej lawv tshwm sim. Lub zog ntau dhau los ntawm qhov tsis txaus tooj liab yog qhov ua rau. Koj tuaj yeem txo qhov tam sim no los ntawm:
Siv tsawg dua LED sawb ib lub hwj chim mov los yog ntxiv ntau tshaj ib lub hwj chim mov rau tib LED sawb ntawm cov ntsiab lus sib txawv
Xaiv 24V tshaj 12V (feem ntau muab tib lub teeb tab sis ib nrab ntawm lub zog ntau)
Xaiv lub zog qis dua
Ua kom cov hlau txoj kab uas hla loj dua rau kev txuas cov xov hlau
Nws tsis yooj yim kom tau txais tooj liab ntau dua yam tsis tau yuav cov teeb ci LED tshiab. Yog tias koj xav tias qhov hluav taws xob poob tuaj yeem yog qhov teeb meem, nrhiav seb tooj liab tau siv ntau npaum li cas.
