Raws li ib tuglag luam wholesale LED teeb,Eurborn muaj tus kheejsab nrauv Hoobkasthiabpwm department, nws yog cov kws tshaj lij hauv kev tsim khoomteeb sab nraum zoov, thiab paub txhua qhov parameter ntawm cov khoom zoo. Hnub no, kuv yuav qhia rau koj paub qhov txawv ntawm qhov tsis tu ncua voltage thiab qhov tam sim no ntawm LED tsav lub zog.
1. Cov khoom siv hluav taws xob tas li tam sim no txhais tau hais tias tam sim no ntws los ntawm kev thauj khoom tseem tsis hloov pauv thaum lub zog hloov pauv. Lub zog hluav taws xob tas li txhais tau hais tias lub zog hluav taws xob tsis hloov pauv thaum lub sijhawm tam sim no ntws los ntawm kev hloov pauv.
2. Qhov thiaj li hu ua qhov tam sim no / qhov hluav taws xob tsis tu ncua txhais tau hais tias qhov tso zis tam sim no / qhov hluav taws xob tseem nyob tsis tu ncua nyob rau hauv qee qhov ntau. Lub premise ntawm "tsis tu ncua" yog nyob rau hauv ib tug tej yam ntau yam. Rau "tam sim no tsis tu ncua", cov zis voltage yuav tsum nyob rau hauv ib tug tej yam ntau yam, thiab rau "tsis tu ncua voltage", cov zis tam sim no yuav tsum nyob rau hauv ib tug tej yam ntau yam. Tshaj qhov ntau qhov "s tas li" tsis tuaj yeem khaws cia. Yog li ntawd, qhov tsis tu ncua ntawm qhov hluav taws xob yuav teeb tsa qhov tsis sib xws ntawm cov ntaub ntawv tso zis tam sim no (qhov tso zis ntau tshaj). Qhov tseeb, tsis muaj ib yam dab tsi li "s tas li" hauv lub ntiaj teb hluav taws xob. Tag nrho cov khoom siv hluav taws xob muaj qhov taw qhia ntawm kev tswj kev thauj khoom. Siv qhov hluav taws xob tas li (voltage) qhov chaw ua piv txwv: raws li koj qhov kev thauj khoom nce, cov zis hluav taws xob yuav tsum poob.
3. Qhov sib txawv ntawm qhov tsis tu ncua voltage qhov chaw thiab qhov tam sim no tsis tu ncua hauv kev txhais:
1) Raws li qhov kev tso cai ntawm kev thauj khoom, qhov tso zis hluav taws xob ntawm qhov hluav taws xob tsis tu ncua yog qhov tsis tu ncua thiab yuav tsis hloov nrog kev hloov ntawm lub load. Feem ntau siv nyob rau hauv qis-power LED modules, thiab tsawg-power LED strips feem ntau siv. Lub qhov hluav taws xob tas li yog qhov peb feem ntau hu ua lub zog tswj hluav taws xob, uas tuaj yeem ua kom ntseeg tau tias qhov hluav taws xob tseem tsis hloov pauv thaum lub load (tso tawm tam sim no) hloov.
2) Raws li qhov kev tso cai ntawm kev thauj khoom, qhov tso zis tam sim no ntawm qhov chaw tam sim no tsis tu ncua thiab yuav tsis hloov nrog kev hloov pauv ntawm cov khoom thauj. Nws feem ntau yog siv nyob rau hauv high-power LEDs thiab high-end low-power khoom. Yog hais tias qhov kev ntsuam xyuas zoo nyob rau hauv cov nqe lus ntawm lub neej, qhov tam sim no qhov chaw LED tsav tsheb yog zoo dua.
Qhov chaw tam sim no tuaj yeem kho nws cov zis voltage raws li thaum lub load hloov, kom cov zis tam sim no tseem tsis hloov. Cov khoom siv hluav taws xob hloov pauv peb tau pom yog qhov tseem ceeb ntawm qhov hluav taws xob tsis tu ncua, thiab lub npe hu ua "tam sim no hloov hluav taws xob hloov hluav taws xob" yog nyob ntawm qhov tsis tu ncua ntawm qhov hluav taws xob, thiab ib qho me me tsis kam sampling resistor ntxiv rau cov zis. Cov theem pem hauv ntej mus rau kev tswj kom tsis tu ncua tam sim no.
4. Yuav ua li cas txheeb xyuas seb nws puas yog qhov hluav taws xob tsis tu ncua lossis qhov tam sim no tsis tu ncua los ntawm cov khoom siv hluav taws xob?
Nws tuaj yeem pom los ntawm daim ntawv lo ntawm cov khoom siv hluav taws xob: yog tias qhov hluav taws xob tso tawm nws txheeb xyuas yog tus nqi tas li (xws li
Vo = 48V), nws yog qhov tsis tu ncua voltage: yog tias nws txheeb xyuas qhov voltage (piv txwv li, Vo yog 45 ~ 90V), nws tuaj yeem txiav txim siab tias qhov no yog qhov tam sim no.
5. Qhov zoo thiab qhov tsis zoo ntawm qhov tsis tu ncua voltage thiab qhov tam sim no tsis tu ncua: qhov hluav taws xob tsis tu ncua tuaj yeem muab qhov hluav taws xob tsis tu ncua rau kev thauj khoom, qhov zoo tshaj qhov hluav taws xob tsis tu ncua
Internal resistance yog xoom thiab tsis tuaj yeem raug luv luv. Qhov tam sim no qhov chaw tuaj yeem muab qhov tam sim no tsis tu ncua rau qhov thauj khoom, thiab qhov zoo tshaj plaws qhov chaw tam sim no muaj qhov tsis muaj qhov tsis txaus sab hauv loj, tsis tuaj yeem qhib txoj kev.
6. LED yog ib qho khoom siv hluav taws xob uas ua haujlwm nrog qhov tam sim no tsis tu ncua (qhov kev ua haujlwm voltage yog qhov ruaj khov, thiab me ntsis offset ntawm nws yuav ua rau muaj kev hloov pauv zoo rau tam sim no). Tsuas yog los ntawm kev siv txoj kev tam sim no tsis tu ncua tuaj yeem ua qhov ci ntsa iab thiab lub neej ntev yuav lav tau tiag tiag. Thaum qhov hluav taws xob tsis tu ncua tsav lub zog hluav taws xob ua haujlwm, nws yog ib qho tsim nyog yuav tsum tau ntxiv ib qho tam sim no module los yog tam sim no limiting resistor rau lub teeb, thaum lub sij hawm tam sim no tsav fais fab mov tsuas muaj qhov tsis tu ncua tam sim no module ntawm qhov tsis tu ncua voltage built-in.
