LED txoj kev teeb pom kev zoo project, ob qho tib si los ntawm lub ntiaj teb ib puag ncig ntawm qhov cuam tshuam, tab sis kuj yog nws cov kev lag luam tshwj xeeb. LED txoj kev teeb fais fab mov yog qhov tseem ceeb tshaj plaws LED txoj kev loj hlob
1, LED txoj kev teeb tsav tsheb yog vim li cas yuav tsum tau tas li?
Cov yam ntxwv ntawm cov khoom siv teeb pom kev zoo LED txiav txim siab nws qhov cuam tshuam los ntawm ib puag ncig, xws li kev hloov pauv kub, LED tam sim no yuav nce, qhov voltage nce, LED tam sim no yuav nce. Ntev dhau qhov ntsuas tam sim no ua haujlwm, yuav ua rau lub neej ntev ntawm LED teeb. LED tsis tu ncua tam sim no nyob rau hauv qhov kub thiab qhov hluav taws xob thiab lwm yam kev hloov pauv ib puag ncig, kom ntseeg tau tias nws cov nqi tam sim no tsis hloov pauv.
2, LED txoj kev teeb lub zog ua haujlwm Voltage
General LED pom zoo ua haujlwm voltage yog 3.0-3.5V, kuaj, feem ntau ntawm kev ua haujlwm hauv 3.2V, yog li kev suav los ntawm 3.2V tsim nyog. N teeb hlaws hauv series nrog tag nrho voltage=3.2 * N.
3, LED txoj kev teeb ua haujlwm tam sim no ntau npaum li cas yog qhov haum tshaj plaws
Piv txwv li, qhov ntsuas tam sim no ntawm LED 350 mA, thiab qee qhov chaw tsim khoom siv los ua, qhov tsim 350 mA, qhov tseeb, qhov haujlwm no nyob rau hauv cov cua sov tam sim no yog qhov hnyav heev, tom qab ob peb qhov kev sib piv, tsim los rau 320 mA yog qhov zoo tagnrho The Sim kom txo cov cua sov, kom muaj zog ntau dua rau hauv qhov pom kev.
4, LED txoj kev teeb tsav tsheb nrog lub dav voltage
Txhawm rau ua LED txoj kev teeb lub zog hluav taws xob nyob rau hauv qhov dav ntawm cov khoom siv hluav taws xob ntau AC 85-265V, tom qab ntawd lub teeb board LED txoj hlua sib txuas yog qhov tseem ceeb heev. Raws li qhov ua tau tsis siv qhov hluav taws xob dav dav, tuaj yeem muab faib ua AC220V, AC110V ntau li ntau tau kev faib tawm, thiaj li ua kom muaj kev ntseeg siab ntawm cov khoom siv hluav taws xob.
