Cov xwm txheej zoo ib yam thiab kev ceev faj rau coj teeb lub teeb puas
Vim tias cov teeb pom kev zoo ntawm LED (feem ntau: LED teeb lub teeb, LED teeb lub teeb, LED qab nthab teeb, thiab lwm yam) muaj cov yam ntxwv ntawm cov pa roj carbon tsawg, kev tiv thaiv ib puag ncig, txuag hluav taws xob, thiab lub neej ntev, lawv tau dhau los ua cov nyiam tshiab ntawm cov neeg siv khoom. Txawm li cas los xij, txhua yam khoom lag luam yuav tsum ua haujlwm zoo nyob rau hauv ib txwm ua haujlwm. Txwv tsis pub, lub teeb yuav&"tawm tsam &";, thiab qhov hnyav yuav ua rau cov khoom qub puas. Hauv qab no, peb yuav tham txog rau qhov laj thawj vim li cas LEDs puas. Nws vam tias cov neeg siv uas tau nyeem kab lus luv luv no tuaj yeem ceev faj hauv lawv lub neej, thiab coj mus rau hauv tus yam ntxwv ntawm kev siv LEDs thiab tiv thaiv lawv.
1. Ua kom lub zog hluav taws xob nce sai. Muaj ntau yam laj thawj rau kev nce lub zog hluav taws xob sai. Piv txwv li, qhov ua tau zoo ntawm lub zog siv hluav taws xob, lossis kev siv tsis raug ntawm tus neeg siv, thiab lwm yam, tuaj yeem ua rau lub zog hluav taws xob hloov pauv sai sai. Kev tswj hluav taws xob zoo yog tus yuam sij
2. Cov hluav taws xob luv ntawm cov khoom siv lossis cov kab ntawv luam tawm lossis lwm cov xov hlau hauv kab hluav taws xob tsim cov khoom siv hluav taws xob luv hauv cheeb tsam ntawm LED txoj kab hluav taws xob, uas ua rau muaj qhov hluav taws xob nyob hauv qhov chaw no. Qhov zoo ntawm cov khoom yog qhov tseem ceeb heev thiab yuav tsum tau xaiv nruj me ntsis.
3. Ib qho LED tau luv-ncig vim nws tus kheej qhov kev puas tsuaj, thiab nws qhov hluav taws xob qub poob tau hloov mus rau lwm lub LEDs. Yuav tsum muaj hnub nyoog los nrhiav qhov teeb meem
4. Qhov kub hauv lub teeb coj yog siab dhau, uas ua rau cov yam ntxwv ntawm LED tsis zoo. Tus yuam sij rau kev ua kom sov sov yog ua haujlwm zoo ntawm cov cua sov ua kom sov.
5. Dej nkag mus rau hauv lub teeb LED, thiab cov dej yog cov coj. Ua haujlwm zoo ntawm kev tiv thaiv dej thiab tiv thaiv dej noo.
6. Thaum sib dhos, kev ua haujlwm tiv thaiv zoo li qub tsis ua tiav, yog li sab hauv ntawm LED tau raug puas tsuaj los ntawm hluav taws xob zoo li qub. Txawm hais tias qhov hluav taws xob ib txwm muaj thiab qhov txiaj ntsig tam sim no tau siv, nws yooj yim heev ua rau puas rau LED. Yuav tsum nqa lub nplhaib zoo li qub
Cov laj thawj no yuav ua rau LED tam sim no nce siab, thiab tsis ntev LED nti yuav raug hlawv tawm vim qhov kub dhau. Raws li peb qhov kev paub dhau los, tom qab LED hlawv, feem ntau ntawm ob tus ncej tau luv-ncig, thiab ib feem me ntawm nws yog qhib Circuit Court. Txhua LED muaj qhov poob qis txog 3.2V. Yog tias nws raug hlawv tawm, txoj hlua ntawm LEDs yuav tsis tso tawm lub teeb. Yog tias qhov hluav taws xob no luv-circuited, nws yuav raug xa mus rau lwm lub LEDs, ua rau muaj hluav taws xob ntau dua hauv lwm lub LEDs, thiab lwm cov LEDs yuav raug hlawv sai dua, thiab txawm tias lub zog siv hluav taws xob yuav yog qhov tseem ceeb. Kev puas tsuaj me me tuaj yeem ua rau muaj xwm txheej loj. LEDs feem ntau teeb tsa hauv qhov chaw siab, nws tsis yooj yim rau nruab, thiab nyuaj dua los kho. Yog li ntawd, kev tiv thaiv ntawm LED yog qhov xav tau tiag tiag, tab sis nws tsis tau raug saib xyuas los ntawm txhua tus neeg tam sim no. Vam tias cov neeg siv tuaj yeem nyiam mloog.
