Qhov project LED txoj kev teeb tsis yog tsuas yog cuam tshuam los ntawm lub ntiaj teb ib puag ncig, tab sis kuj nws cov kev lag luam tshwj xeeb. LED txoj kev teeb fais fab mov yog qhov tseem ceeb tshaj plaws ntawm kev txhim kho LED
1. Vim li cas tus tsav tsheb LED txoj kev teeb yuav tsum nyob tas li? Cov yam ntxwv ntawm LED teeb pom kev zoo cov ntaub ntawv txiav txim siab tias nws cuam tshuam los ntawm ib puag ncig, xws li kev hloov pauv kub, LED tam sim no nce, voltage nce, thiab LED tam sim no nce. Tshaj qhov ntsuas tam sim no rau lub sijhawm ntev yuav ua rau lub neej ua haujlwm luv ntawm LED teeb. LED tsis tu ncua tam sim no yog los xyuas kom meej tias nws cov nqi tam sim no tseem tsis hloov pauv thaum ib puag ncig yam xws li kub thiab voltage hloov.
2. Kev ua hauj lwm voltage ntawm LED txoj kev teeb fais fab mov Qhov pom zoo ua hauj lwm voltage ntawm LED yog 3.0-3.5V. Tom qab kev sim, feem ntau ntawm lawv ua hauj lwm ntawm 3.2V, yog li nws yog tsim nyog los xam raws li 3.2V. N teeb hlaws hauv series nrog tag nrho voltage=3.2 * N.
3. Dab tsi yog qhov tsim nyog ua haujlwm tam sim no rau LED txoj kev teeb? Piv txwv li, qhov ntsuas tam sim no ntawm LEDs yog 350 mA, thiab qee qhov chaw tsim khoom siv los ua nws, thiab nws yog tsim los ua 350 mA. Qhov tseeb, kev ua haujlwm no yog qhov hnyav heev nyob rau hauv cov cua sov tam sim no, tom qab ob peb zaug Rau kev sib piv, kev tsim ntawm 320mAh yog qhov zoo tshaj plaws los sim txo cov cua sov thiab tso cai rau ntau lub zog hloov mus rau qhov pom kev pom.
4. Dav voltage LED txoj kev teeb tsav tsheb txhawm rau ua kom lub LED txoj kev teeb hluav taws xob nyob rau hauv ntau yam ntawm AC 85-265V input voltage range, series-parallel hom ntawm lub teeb vaj huam sib luag LED yog ib qho tseem ceeb heev. Tsis txhob siv qhov hluav taws xob dav dav kom ntau li ntau tau, uas tuaj yeem muab faib ua AC220V thiab AC110V kom ntau li ntau tau kom ntseeg tau tias muaj kev ntseeg siab ntawm cov khoom siv hluav taws xob.
