Yuav Ua Li Cas Txheeb Xyuas Qhov Tsis Zoo ntawm Lub Teeb-emitting Diode Teeb Bead

Dab tsi yog vim li cas vim li cas lub teeb hlaws tsis tau teeb rau ntawm lub rooj tsavxwm? Yuav kuaj li cas? Ua ntej, xyuas seb lub Circuit Court siv li cas, thiab tom qab ntawd ua ib qho kev ntsuam xyuas tshwj xeeb raws li qhov tshwj xeeb Circuit Court. Txawm li cas los xij, feem ntau yog vim li cas LEDs tau txais txoj cai thiab qhov tsis zoo ntawm LED thaum lub sijhawm teeb tsa lossis vuam txheej txheem ua ntej kev teeb tsa. Qhov tseeb vuam tsis muaj zog), kev vuam virtual yog qhov laj thawj tseem ceeb rau qhov tsis ua haujlwm, tshwj xeeb tshaj yog rau cov novices uas tsis muaj kev paub txog vuam. Qhov teeb meem no feem ntau yuav. Nws kuj tseem yog tias cov hluav taws xob hlau xau ua rau LED tawg luv luv. Muaj ib feem ntawm ib feem ntawm lub voj voog tsav tsheb los txuas lossis vuam zoo, thiab qee qhov kev sib txuas kuj tseem yog qhov kev hloov kho ntawm tus nqi tsis zoo. Ua ntej lub voj voog raug teeb tsa, xyuas cov tshev thiab xyuas kom zoo ua ntej lub hwj chim. Yog tias lub teeb tsis tau qhib, lub hwj chim yuav tsum tau muab tua tam sim ntawd, thiab tom qab ntawd kev tshuaj xyuas yuav tsum tau ua. Koj tsis tuaj yeem khob lub rooj tsav xwm hauv Circuit Court kom sim nrhiav qhov txhaum. nyob rau hauv no txoj kev. Yog tias nws yog ib lub voj voog nrog lub lim dej capacitor, ua ntej ntawm tag nrho cov, koj yuav tsum tau siv lub hau ntswj los yog xaim kom tso tawm ob txhais taw ntawm lub lim capacitor ua ntej kuaj nws. Cov kauj ruam no tseem ceeb heev! Vim hais tias lub lim capacitor muaj qhov hluav taws xob siab tshaj 1.4 npaug ntawm lub zog hluav taws xob (ntau dua 1.4 npaug ntawm lub zog hluav taws xob hluav taws xob (Piv txwv li, thaum 220V fais fab mov tuaj yeem siab li 310V), thiaj li tsis ua rau tib neeg lub cev puas tsuaj. los yog rhuav tshem lub LED thaum lub capacitance ciaj sia nyob rau hauv lub capacitor los yog lub sij hawm lub Circuit Court txuas nrog! txhua LED. Ua tib zoo saib xyuas lub polarity ntawm lub roj teeb lub zog raws li qhov polarity ntawm LED, yog li siv cov polarity ntawm LED, kom xyuas seb txhua lub LED puas tuaj yeem nyob. Kev tshuaj xyuas ntawm lub voj voog tsav tsheb, koj yuav tsum ua tib zoo xyuas seb lub Circuit Court puas yog raws li daim duab kos. Ua tib zoo saib xyuas tus choj rectifier (qhov ntev ko taw yog qhov zoo electrode tso zis, kab pheeb ces kaum yog qhov tsis zoo electrode tso tawm, ob txhais taw yog AC input) los yog lub rectifier diode, thiab qhov voltage voltage diode yeeb nkab seb lub polarity puas yog. (ib kawg nrog ib txoj kab dub lossis dawb yog qhov tsis zoo), thiab xyuas seb peb lub electrodes ntawm cov siv lead ua triode los yog qhov hluav taws xob sib xyaw ua ke yog qhov tsis raug. Zoo, qhov kev piav qhia ntawm glow diode nyob ntawm no,
