Qhov sib txawv voltages ntawm LED strips yog 12VDC thiab 24VDC, thiab lawv cov nqi yog tib yam. Thaum koj npaj yuav yuav LED strips, koj yuav muaj lus nug, qhov txawv ntawm 12VDC strips thiab 24VDC strips yog dab tsi? Kuv yuav tsum xaiv qhov twg?
LEDYi feem ntau muab ob qho tib si 12VDC thiab 24VDC LED strips. Raws li ib txwm muaj, qhov sib txawv ntawm 12VDC LED sawb thiab 24VDC LED sawb tsis loj dhau, tsuav yog koj xaiv lub hwj huam kom raug.
Yog tias koj xav tau kev txiav luv luv, peb pom zoo xaiv 12VDC LED sawb. Rau LED sawb nrog tib lub LED kom muaj nuj nqis, qhov txiav ntev ntawm 12VDC LED sawb yog ib nrab ntawm 24V LED sawb. Qhov no ua rau koj yooj yim dua los txiav cov LED sawb mus rau qhov ntev koj xav tau.
Yog hais tias koj xav tau ib tug ntev linear khiav thiab ntau dua luminous efficiency, peb xav kom xaiv 24VDC LED strips.
Yog tias koj xav paub ntau ntxiv txog kev ua haujlwm, nyeem hauv qab no kom paub ntau qhov sib txawv:
12VDC LED sawb nrog luv luv txiav ntev
Feem ntau cov LED chips khiav ntawm 3VDC lub zog tsis hais seb lawv puas tau nruab rau ntawm 12V sawb lossis 24V sawb. Qhov tseeb, tib lub nti LED uas ua haujlwm ntawm 12V sawb kuj tseem tuaj yeem txuas rau ntawm 24V sawb. Dab tsi ua rau qhov txawv yog li cas lub strip circuitry tsim.
LED Strips yog wired nyob rau hauv pawg ntawm LEDs. Qhov loj ntawm lub
pawg nyob ntawm qhov voltage ntawm lub sawb. Ib tug 12V sawb muaj 3 LEDs, thiab ib tug 24V sawb muaj 6 LEDs los yog 7 LEDs, txawm mus txog rau 8 LEDs. Cov kab txiav yog nyob nruab nrab ntawm cov pab pawg. Yog li ntawd, qhov me me ntawm txhua pawg ntawm LEDs, qhov ze ua ke ntawm cov kab txiav tuaj yeem ua tau.
Piv txwv li, saib cov duab kos ntawm 12V thiab 24V strips hauv qab no:
Ib qho hluav taws xob qis dua 12VDC sawb nrog cov kab txiav kom ze yuav zoo yog tias koj lub installation muaj ntau lub ces kaum nrog luv luv. Qhov no tuaj yeem pab txo qis "tsaus" thaj tsam ntawm cov ces kaum.
Txhawm rau kom tau txais txiaj ntsig zoo ntawm Kev Ua Si Ntev ntawm 24VDC LED sawb thiab luv luv txiav ntev ntawm 5VDC LED sawb, peb tau tsim Mini txiav LED Sawb, 1 LED ib ntus ntawm 24VDC.
12V LED sawb muaj ntau yam ntawm cov ntawv thov scenarios
Ntawm qhov tod tes, 12 VDC yog ib qho hluav taws xob ntau, yog li LED strip compatibility yuav tshem tawm qhov xav tau rau cov khoom siv hluav taws xob ntxiv. Piv txwv li, yog tias koj tab tom txhim kho lub teeb hauv lub tsheb, 12 VDC LED sawb teeb feem ntau tuaj yeem txuas ncaj qha rau cov hluav taws xob uas twb muaj lawm. Txawm hais tias muaj qhov tshwj xeeb rau qhov no, thiab nws yog ib qho tseem ceeb uas yuav tsum tau xyuas koj qhov system uas twb muaj lawm ua ntej kev yuav khoom, 12V LED strips tuaj yeem muab cov kev daws teeb meem yooj yim dua rau ntau zaus.
24V LED sawb, ntev linear khiav
Ib txoj hlua hluav taws xob ntau dua feem ntau yuav muaj peev xwm khiav tau ntev dua yam tsis muaj kev txom nyem los ntawm qhov cuam tshuam ntawm qhov poob qis.
Voltage poob yog dab tsi?
Voltage poob ua rau LED strips poob lawv qhov kev siv zog thaum lawv ua ntev dua. LEDs thaum pib ntawm lub sawb (ze ntawm lub hwj chim mov) yuav ci ntsa iab. Nyob rau hauv sib piv, LEDs nyob rau thaum xaus ntawm lub sawb yuav muaj ib tug dimmed tsos.
Vim li cas voltage poob tshwm sim?
Txhua qhov ntev ntawm cov hlau muaj qee qhov hluav taws xob tiv thaiv. Qhov ntev ntawm cov hlau, ntau qhov kev tiv thaiv. Hluav taws xob tsis kam ua rau qhov hluav taws xob poob, thiab qhov hluav taws xob poob ua rau koj cov LEDs dim.
Yog li ntawd, LEDs ntawm qhov kawg ntawm ib lub sawb yuav ib txwm tau txais tsawg dua qhov hluav taws xob tshaj li qhov pib. Yog tias koj ua kom lub sawb ntev txaus, qhov kev poob qis yuav dhau los ua qhov tseem ceeb txaus ua rau pom qhov txawv ntawm qhov ci.
Yuav ua li cas ntau dua voltage txo cov teebmeem ntawm voltage poob?
Ua ntej, koj yuav tsum nkag siab tias tag nrho cov khoom ntawm LED sawb txuas nrog li cas.
Feem ntau cov LED chips khiav ntawm 3V DC lub zog tsis hais seb lawv puas tau teeb tsa ntawm 12V sawb lossis 24V sawb. Qhov tseeb, tib lub nti LED uas ua haujlwm ntawm 12V sawb kuj tseem tuaj yeem txuas rau ntawm 24V sawb. Dab tsi ua rau qhov txawv yog li cas lub strip circuitry tsim.
LED chips yog wired nyob rau hauv series rau hauv pawg. Txhua pab pawg muaj qee cov chips LED thiab cov resistor. Tag nrho qhov hluav taws xob poob thoob plaws pawg yuav tsum sib npaug rau tag nrho qhov hluav taws xob ntawm lub sawb (saib daim duab hauv qab).
Tom qab ntawd, txhua pab pawg yog xaim nyob rau hauv parallel thiab teem caij raws qhov ntev ntawm lub sawb.
Txog tam sim no, ceeb toom (saib daim duab saum toj no) tias pawg loj ntawm 24V sawb yog 7 LEDs piv rau tsuas yog 3 LEDs rau 12V. Kuv yuav piav qhia vim li cas qhov no tseem ceeb hauv qab no.
Txhua lub xov hlau muaj qee qhov kev tiv thaiv hluav taws xob raug thawb los ntawm nws. Qhov ntev ntawm cov hlau tau txais, qhov loj dua qhov tsis kam (thiab qhov voltage poob) tau txais. Thaum kawg, nws tau txais loj txaus los cuam tshuam lub teeb ci LED. Hauv qab no yog ib qho piv txwv ntawm yuav ua li cas nws yuav tshwm sim ntawm 12V sawb.
Daim ntawv ceeb toom hauv daim duab saum toj no hais tias qhov hluav taws xob thoob plaws LEDs tau poob ntawm 3.0V rau 2.75V.
Thaum peb hloov mus rau 24V, ob yam tshwm sim uas txo qhov voltage poob.
Thaum qhov hluav taws xob tau txais ob npaug (12V txog 24V), tam sim no yog halved (Ohm txoj cai P = U * I). Qhov ntawd ua rau lub zog poob ntawm cov xaim ntev yuav raug txo los ntawm ib nrab thiab. Yog li es tsis txhob 1V poob, nws dhau los ua 0.5V poob.
Cov nyhuv ntawm 0.5V poob yog sib cais ntawm yim seem hauv Circuit Court (piv rau 4 ntawm 12V).
Daim ntawv ceeb toom ntawm no tias qhov hluav taws xob thoob plaws LEDs tsuas yog poob rau 2.9375V piv rau 2.75V nrog 12V sawb.
Yog tias koj muaj ib daim ntawv thov uas yuav tsum tau siv cov strips ntev, nws yuav yog ib lub tswv yim zoo uas siv 24V strips. Tab sis, txawm tias 24V strips muaj qhov txwv. Tej zaum koj yuav tau siv lwm cov tswv yim los txwv koj cov LEDs ntawm qhov kawg. Piv txwv li, siv peb Super Ntev Ntev Tam Sim No LED Sawb.
24V LED sawb tuaj yeem ua tau zoo dua
Cov hluav taws xob siab dua tuaj yeem ua haujlwm tau zoo dua.
Txhua lub sij hawm muaj qhov hluav taws xob hla lub resistor, nws txhais tau hais tias lub zog tau hloov mus rau qhov kub tsis yog lub teeb. Yog li ntawd, cov resistors nyob rau hauv cov duab saum toj no yog tsim nyog, tab sis lawv kuj yog ib qhov chaw ntawm nkim zog.
| Tag nrho voltage ntawm strip | Voltage ntawm resistor | % Fais fab "nkim" ntawm resistors |
| 5V (1 LED ib pab pawg) | 2V | 40% |
| 12V (3 LEDs ib pab pawg) | 3V | 25% |
| 24V (7 LEDs ib pab pawg) | 3V | 12.5% |
Nws yog ib qho yooj yim kom pom tias cov kab hluav taws xob ntau dua raug kev txom nyem los ntawm kev siv hluav taws xob tsawg. LEDs siv lub zog me me uas qhov no tsis ntxiv ntau rau kev teeb tsa me me. Txawm li cas los xij, qhov sib txawv ntawm kev siv hluav taws xob tuaj yeem ua qhov tseem ceeb rau tag nrho chav tsev lossis kev teeb tsa kev lag luam.
Peb tau tsim high-efficiency LED strips, 8 LEDs ib ntus, mus txog 190LM / w.
Qhov no yog tib txoj cai raws li high-voltage fais fab kis. Qhov siab dua qhov voltage, qhov tam sim no me dua. Raws li Ohm txoj cai, qhov voltage poob Vpoob= I * R, lub zog hluav taws xob hloov mus rau cua sov P = U * I = (I * R) * I = I 2 * R.
24V LED sawb yuav tsum tau tsawg dua tus neeg xyuas pib ntsuas
Lub zog hluav taws xob yog txiav txim siab los ntawm qhov sib npaug P = V * I. Yuav kom tswj tau tib lub zog (P), yog tias qhov hluav taws xob (V) nce mus, tam sim no (I) yuav tsum nqis los ntawm qhov sib npaug.
Yog tias peb khaws 48W raws li peb lub hom phiaj tso tawm ua piv txwv, 12V system yuav xav tau 4 Amps (12V x 4A = 48W), thaum lub 24V system tsuas xav tau 2 Amps (24V x 2A = 48W).
Cias muab, 24V LED system yuav kos ib nrab ntawm cov nqi tam sim no raws li 12V LED system kom ua tiav tib lub zog.
Yog vim li cas yog no thiaj tseem ceeb?
Tag nrho tam sim no, ntau dua li qhov hluav taws xob, txiav txim siab lub thickness thiab dav ntawm tooj liab conductors xav tau los hloov hluav taws xob yam xyuam xim.
Yog hais tias ntau dhau ntawm tam sim no raug yuam los ntawm ib qho me me los yog nqaim tooj liab conductor, kev tiv thaiv hauv tus neeg xyuas pib yuav ua qhov tseem ceeb thiab ua rau muaj kev poob qis thiab kev tsim hluav taws xob. Hauv qhov xwm txheej hnyav heev, qhov no tuaj yeem ua rau hluav taws kub.
Tag nrho lwm qhov sib npaug, 24V LED qhov system tuaj yeem tawm mus nrog ib nrab ntawm cov khoom siv hluav taws xob. Koj tuaj yeem siv lub voltage poob lub laij lej kom ntseeg tau tias koj tseem siv cov ntsuas hluav taws xob txaus rau koj cov phiaj xwm LED sawb.
Cov khoom siv hluav taws xob me me rau 24V LED sawb
Zoo li tus neeg xyuas pib qhov loj me, lub hwj chim mov loj kuj tau txiav txim siab los ntawm qhov tam sim no ntau dua li qhov hluav taws xob. Ib feem ntawm qhov no tseem cuam tshuam los ntawm physics kev sib raug zoo ntawm cov hluav taws xob tam sim no thiab tus neeg xyuas pib qhov xav tau, ntau npaum li lub zog hluav taws xob hauv cov xaim hluav taws xob muaj xws li tooj liab thaiv.
Lub hwj chim loj tuaj yeem yog qhov tseem ceeb thaum ua haujlwm nrog cov haujlwm xws li LED sawb teeb nyob rau hauv qab txee qhov chaw uas yuav muaj qhov chaw txwv.
