Raws li kev tshaj lij Led Sawb chaw tsim tshuaj paus, peb nkag siab tias kev ci ntsa iab yog qhov tseem ceeb rau kev lag luam thiab cov cuab yeej teeb pom kev zoo. Thaum coj ib daim hlab yog uas tau tsav nyob rau hauv tas li hom tam sim no, txhua tus coj tau zoo tam sim no nws yuav tsum tau, ua kom pom kev zoo lub teeb pom kev raws tag nrho cov sawb.
Tsis zoo li tas mus voltage systems, qhov twg voltiations nyob rau hauv ntej voltage tuaj yeem ua rau kev tsav tsheb tsis sib xws, kev tsav tsheb tam sim no, xa lub cev txhim khu kev qha.
NtawmUa pluxled, peb muab ob qho tib si kev daws teeb meem tsis tu ncua thiab txuas ntxiv rau peb cov neeg siv B2b tuaj yeem xaiv cov kev xaiv zoo rau lawv cov teeb pom kev zoo.
1. LEDs yog tam sim no -} driven pab kiag li lawm
Ib qho LED lub teeb tawm hluav taws xob yog ncaj qha rau tusniaj hnubntws mus los ntawm nws, tsis yog lub voltage.
Cov voltage rau pem hauv ntej ntawm ib qho kev sib txawv me ntsis me ntsis vim yog tsim kom muaj kev thev thiab ntsuas kub.
Yog tias koj thov ib qho hluav taws xob ruaj khov hla ntau tus LEDs, qee qhov yuav kos tau ntau dua li lwm tus vim tias lawv cov hluav taws xob sib txawv me ntsis. Qhov ua rau noCi ntsa iab variatedraws txoj kab txaij.
2. Constant tam sim no hom txhim kho tam sim no
A Kev tsav tsheb tas mus liKho lub voltage dynamically kom tau tuav ib txheej tam sim no.
Txhua tus coj (lossis coj ntu) tau txais tib yam tam sim no, yog li covLub teeb tawm yog khaub ncaws.
Txawm hais tias muaj qhov sib txawv me ntsis nyob rau hauv cov voltage rau pem hauv ntej ntawm sawb, tus neeg tsav nyiaj tau them nyiaj.
3. VOLTORAGE HOM VS Tam Sim No
|
Hom |
Nws ua haujlwm li cas |
Nyhuv rau ci ntsa iab |
|
Qhov Voltage tas mus li(piv txwv li, 24V / 48 khoom noj) |
Taag Voltage Hla Sawb |
Kev ci ci tuaj yeem sib txawv vim tau coj mus rau pem hauv ntej voltage sib txawv; Cov kab ntev ntev yuav dim mus rau qhov kawg |
|
Constant tam sim no |
Kho cov hluav taws xob kom muaj kev ruaj khov tam sim no |
Txhua tus coj tau zoo li qub tam sim no → zoo sib xws nrog txoj hlua khi |
4. Cov txiaj ntsig ntxiv ntawm tas mus li tam sim no
Tiv thaiv LEDs los ntawm overcurrent thiab thermal khiav tawm.
Tso cai rau ntev dua tsis muaj qhov tsis muaj kev cuam tshuam voltage poob lawm.
Ntau cov thermal thiab kev ua haujlwm kho qhov muag.
5. Cov teeb ci ntsa iab yog qhov tseem ceeb hauv kev tsim kev lag luam. Nrog kev tsav tsheb tas li, txhua LED tau txais qhov tam sim no ruaj khov, kom muaj kev sib tw ua rau muaj qhov ua rau muaj qhov tseeb thoob plaws. Hauv qab no yog peb cov kev daws teeb meem tam sim no los ntawmUa pluxled.
48V Tas Thawm Tam Sim No Led Sawb Teeb
24V tas li tam sim no LED Sawb Teeb
24V Cob Constant Tam Sim No Led Sawb Teeb
✅ Hauv ntej:Qhov tam sim no tas mus li txhua tus coj pom tib yam tam sim no, uas yog dab tsi tiag txiav txim siab ci. Kev sib txawv ntawm cov hluav taws xob tawm hws nyob ntawm cov kev sib txawv me me hauv LED rau pem hauv ntej voltage, yog li ci ci hloov
