LED tsav tsheb
LED tsav tsheb yog dab tsi?
Tus tsav tsheb LED yog lub tshuab hluav taws xob hloov kho hluav taws xob uas tsav lub zog ua haujlwm ntawm LED teeb lossis LED module sib dhos.Vim yog cov yam ntxwv ntawm LED PN kev sib tshuam, nws tuaj yeem hloov mus rau qhov hluav taws xob thiab qhov hloov pauv tam sim no ntawm cov khoom siv hluav taws xob yog nqaim heev, qhov sib txawv me ntsis yuav tsis tuaj yeem ua rau lub teeb ci LED lossis teeb pom kev zoo raug txo qis, lossis ua kom lub neej luv. ntawm cov nti los yog hlawv.Cov khoom siv hluav taws xob tam sim no thiab cov khoom siv roj teeb uas siv hluav taws xob tsis haum rau cov khoom siv ncaj qha rau LEDs, thiab LED tsav tsheb yog cov khoom siv hluav taws xob uas tuaj yeem tsav lub LED kom ua haujlwm ntawm qhov zoo tshaj plaws voltage lossis tam sim no.
Daim ntawv thov
Kev siv ntawm LED tsav tsheb.
Raws li LEDs tau siv nyob rau hauv yuav luag txhua qhov chaw ntawm kev siv hluav taws xob, nrog yuav luag tsis muaj kev hloov pauv hauv kev siv lub teeb ci, lub teeb xim, thiab kev tswj / tawm, LED tsav tsheb tau dhau los ua ib qho khoom siv servo, ua rau ntau tsev neeg ntawm cov khoom siv.Tus tsav tsheb LED yooj yim tshaj plaws (yog tias koj tuaj yeem hu nws qhov ntawd) yog ib lossis ob peb qhov sib npaug ntawm cov khoom sib txuas hauv ib lub voj voog uas faib cov tam sim no thiab qhov hluav taws xob, thiab nws tsis yog ib qho khoom muag txhua.Rau ntau daim ntawv thov kev lag luam uas yuav tsum tau muaj qhov ruaj khov tam sim no thiab qhov hluav taws xob tso tawm, ntau qhov kev daws teeb meem nrog lub zog muaj peev xwm ua tau zoo tau tsim.Kev ua tiav ntawm cov kev daws teeb meem no feem ntau xav tau kev tsim hluav taws xob ntau dua, qhov tseem ceeb ntawm qhov uas yog kev sib koom ua ke ntawm LED tsav ICs.Los ntawm kev teeb tsa cov kev txhawb nqa sib txawv ntawm qhov chaw nruab nrab ntawm LED tsav tsheb ICs, cov kev daws teeb meem tuaj yeem tsim rau cov kev siv LED sib txawv, los ntawm cov xov tooj ntawm tes me me tso saib cov teeb pom kev zoo thiab cov teeb pom kev zoo ntawm cov tsav tsheb mus rau high-power LED txoj kev teeb pom kev zoo thiab cov teeb pom kev zoo sab nraum zoov.
Kev tsim thiab muab khoom ntawm ntau lub zog hluav taws xob LED tsav tsheb feem ntau yog ua los ntawm cov tuam txhab tshwj xeeb.Cov tuam txhab no ntim lawv rau hauv cov qauv thiab tom qab ntawd muab lawv rau cov tuam txhab tsim khoom siv LED kawg.Qhov tshwj xeeb tseem ceeb ntawm LED tsav tsheb nyob rau hauv LED daim ntawv thov thiab ntau yam ntawm cov neeg siv yuav tsum tau ua rau LED tsav IC, lub plawv ntawm LED tsav tsheb, lub ntsiab tseem ceeb nyob rau hauv tag nrho cov cuab yeej technology.Tus tsav tsheb yog qhov tseem ceeb ntawm LED teeb pom kev zoo.Nrog rau kev loj hlob ntawm LED nti technology, qhov zoo ntawm LED teeb qhov chaw tau dhau los ua kev ntseeg siab tias nyob rau hauv ntau qhov teeb meem ntawm LED luminaires tsis ua haujlwm los ntawm tus neeg tsav tsheb.
Kev piav qhia
LP8861-Q1 yog automotive high-efficiency, low-EMI, yooj yim-rau-siv LED tsav tsheb nrog integrated boost / SEPIC converter.Nws muaj plaub qhov kev txiav txim siab tam sim no uas tuaj yeem muab qhov siab dimming piv kev ci ntsa iab nrog PWM cov teeb liab tawm tswv yim.
Lub boost / SEPIC converter muaj kev hloov pauv cov zis hluav taws xob tswj raws li LED tam sim no lub dab dej hauv qhov hluav taws xob.Cov yam ntxwv no txo qis kev siv hluav taws xob los ntawm kev kho qhov hluav taws xob kom qis qis txaus hauv txhua qhov xwm txheej.Lub boost / SEPIC converter txhawb kev sib kis spectrum rau kev hloov zaus thiab kev sib txuas sab nraud nrog rau tus pin tshwj xeeb.Qhov dav-ntau zaus hloov tau tso cai rau LP8861-Q1 kom tsis txhob muaj kev cuam tshuam rau AM xov tooj cua band.
LP8861-Q1 muaj kev xaiv los tsav lub p-FET sab nraud kom tshem tawm cov khoom siv nkag los ntawm lub kaw lus thaum muaj kev ua txhaum thiab txo qis inrush tam sim no thiab standby zog noj.Cov cuab yeej tuaj yeem txo cov LED tam sim no raws li qhov ntsuas kub nrog NTC sensor sab nraud los tiv thaiv LED los ntawm overheating thiab txuas ntxiv LED lub neej.
Lub input voltage ntau rau LP8861-Q1 yog los ntawm 4.5 V mus rau 40 V los txhawb lub tsheb nres / pib thiab thauj khoom pov tseg.LP8861-Q1 integrates nws kim heev nrhiav kom tau thiab tiv thaiv nta.
