Vim li cas thiaj muaj qhov sib txawv ntawm 3V, 6V, 9VLED Patch Lamp Beads?

LED teeb hlaws yog tiag tiag lub teeb-emitting diode. Tom qab loading ib qho voltage thiab tam sim no, nws yuav ci. Feem ntau hais lus, qhov hluav taws xob ntawm ib qho LED nti yog li 3V, thiab tam sim no yog 30mA. Rau qhov voltage thiab tam sim no ntawm LED teeb hlaws, feem ntau ntawm lawv yog nyob rau hauv cov txheej txheem ntawm LED ntim. Lub 0.2W LED teeb hlaws siv nyob rau hauv lub teeb raj yog ua los ntawm ob LED chips nyob rau hauv parallel, uas yog, 3V, 60mA. Rau cov high-voltage LED 9V teeb hlaws dai uas siv feem ntau, peb LED chips txuas nrog hauv series, uas yog, 9V, 30mA. Vim hais tias LED teeb hlaws dai yog co-authored los ntawm ntau yam LED chips, muaj ntau yam specifications ntawm LED teeb hlaws dai, thiab muaj ntau hom voltage. Lub teeb tshwj xeeb npaum li cas? Koj tuaj yeem pom ntau npaum li cas LED chips yog tsim los ntawm lub teeb hlaws. Tau kawg, vim hais tias LED nti yog me me, cov xov kub ntawm cov hlau lead tseem ceeb yog me me. Nws tsuas yog kwv yees kom pom kev. Koj yuav tsum sim nws nrog DC qhov chaw. Txawm li cas los xij, nws yog 3V, 6V, 9V, thiab lwm yam. Tau kawg, muaj ntau ntau V teeb hlaws dai. Qhov no nyob ntawm seb hom teeb hlaws koj xav tau tiag tiag siv?. Tsuas yog 3V teeb hlaws dai, koj tuaj yeem siv cov ntaub ntawv ntau-meter diode los teeb lub teeb hlaws. Yog li ntawd, tsis zoo li ntawd. Rau LED teeb hlaws dai uas tsis paub qhov voltage, nws tsuas yog ntsuas los ntawm DC. Los ntawm kos mus rau loj, thaum lub teeb hlaws dai me ntsis ci, qhov hluav taws xob ntawm lub sijhawm no yog kwv yees qhov hluav taws xob ntawm LED teeb hlaws. Rau COB teeb hlaws, nws yog qhov tseeb, tab sis COB encapsulates ntau LED chips, thiab qhov voltage thiab tam sim no yuav loj heev. Txoj kev lees paub ntawm COB teeb hluav taws xob thiab tam sim no kuj tau lees paub los ntawm DC qhov chaw. Txhua qhov tshwj xeeb ntawm cov hlaws teeb muaj lawv tus kheej cov yam ntxwv, qee qhov muaj nqi ntau dua, thiab qee qhov muaj kev ua tau zoo dua. LED teeb hlaws ntawm tib qhov tshwj xeeb ntawm txhua qhov chaw tsim khoom kuj tseem yuav txawv, yog li LED teeb hlaws hlaws tsis zoo los yog phem. Ntev npaum li nws siv, nws yuav ua nws lub luag haujlwm loj tshaj plaws. Kev tshaj lij customization ntawm ntau yam LED thaj teeb hlaws. Yog tias koj xav tau sab laj nrog peb cov neeg siv khoom, peb yuav daws qhov teeb meem rau koj.
