LED tsav tsheb yog dab tsi?
Feem ntau hais lus, LED tsav tsheb yog lub converter. Nws txoj haujlwm yog los hloov peb cov khoom siv uas nquag siv lossis lwm yam khoom siv hluav taws xob rau hauv LED haum rau kev siv hluav taws xob thiab tam sim no. Los ntawm nws txoj kev hloov dua siab tshiab coj mus ua haujlwm kom zoo. Raws li yog hais tias peb xav unscrew ib tug txiv ntseej, peb yuav tsum siv tib hom spanner.
Kev ua haujlwm ntawm tus tsav tsheb LED thiab yav dhau los peb tau siv lub quartz teeb transformer, fluorescent teeb, lub zog txuag teeb, hlau halide teeb ballasts thiab tsis muaj qhov sib txawv. Txhua yam txhawm rau ua kom cov khoom siv teeb pom kev zoo tuaj yeem ruaj khov thiab ua haujlwm li qub. Yog li nws feem ntau hu ua led ballast, led transformer, tab sis cov kws kho mob feem ntau tseem hu ua tus tsav tsheb, ib qho yog txhawm rau paub qhov txawv ntawm lwm cov converters, vim tias txoj haujlwm ntawm peb qhov sib txawv. Peb tuaj yeem qhia peb cov lus qhuab qhia. Yog li ntawd, peb yuav tsum coj tus tsav tsheb mus nthuav qhia.
Hom LED tsav tsheb
Kev ua lag luam feem ntau siv coj lub teeb tsav tsheb raws li hom tsav tsheb tau muab faib ua ob hom, ib qho yog qhov tsav tam sim no, tsis tu ncua tsav tam sim no yog tus cwj pwm los ntawm cov zis tam sim no tsis tu ncua, cov zis hluav taws xob hauv ntau qhov kev hloov pauv. Yog li peb feem ntau pom nyob rau hauv kev ua lag luam tsav lub plhaub yog cim (tso zis: DC ** V--**V ***mA+-5% ) Qhov no txhais tau hais tias cov zis voltage nyob rau hauv ib tug tej yam ntau yam, tam sim no yog pes tsawg milliamps.
Lwm hom yog qhov hluav taws xob tsis tu ncua. Cov yam ntxwv ntawm qhov hluav taws xob tsis tu ncua yog tias qhov tso zis hluav taws xob yog tsau, thiab qhov tam sim no sib txawv nrog cov naj npawb ntawm cov teeb sib txuas hauv qhov siab tshaj plaws. Feem ntau cim rau ntawm lub plhaub (tso zis: DC ** V ** A) yog hais txog qhov tso zis ntawm tus naj npawb ntawm cov volts ntawm qhov voltage, qhov siab tshaj plaws tso zis tam sim no yog ntau npaum li cas. coj kev lag luam yog ib txwm tso zis 5V, 12V, 24V thiab hais txog.
Kev siv ntawm LED tsav tsheb
Daim ntawv thov ntawm tus tsav tsheb LED nyob ntawm qhov tsis muaj kev coj peb xav tsav. Qhov ob qhov tseem ceeb tshaj plaws yog input voltage thiab input tam sim no.
Tom qab paub qhov input voltage thiab input tam sim no ntawm lub teeb lub rooj tsavxwm, peb xaiv tus coj tsav tsheb siv tau. Piv txwv li, cov xwm txheej hauv qab no. Paub tias qhov input voltage ntawm lub teeb lub rooj tsavxwm yog 37-40V, lub input tam sim no yog 300mA, ces koj tuaj yeem xaiv tus tsav tsheb LED tso zis voltage muaj nws, tam sim no yuav luag tib yam. Kev sib txuam, qhov voltage siab dua lossis qis dua tsis tuaj yeem ua tau, yuav tsum suav nrog. Tsis tas li ntawd yuav muaj flickering.
Thaum kawg, peb tsuas yog yuav tsum tau solder tus tsav tsheb lossis txuas cov xov hlau raws li qhov zoo thiab qhov tsis zoo ntawm lub teeb board.
