Cov kev ceev faj rau xaiv LED raj fais fab mov yog dab tsi?
Lub hwj chim ntawm cov raj coj yog lub plawv ntawm cov raj coj, uas cuam tshuam ncaj qha rau nws lub neej. Ua tib zoo mloog cov ntsiab lus hauv qab no:
1. Vim li cas yuav tsum muaj lub raj xa hluav taws xob LED muaj qhov tsis tu ncua?
Cov yam ntxwv ntawm LED semiconductors txiav txim siab tias nws cuam tshuam loj heev los ntawm ib puag ncig. Piv txwv, yog tias qhov kub nce, qhov tam sim no ntawm LED yuav nce; qhov tam sim no ntawm LED tseem yuav nce ntxiv. Tshaj qhov ntsuas tam sim no yuav ua rau lub neej luv ntawm LED. Thiab qhov tam sim no LED yog txhawm rau xyuas kom nws cov haujlwm tam sim no tseem tsis hloov pauv thaum ib puag ncig yam xws li ntsuas kub thiab hloov pauv. Qhov tseeb xav tau rau qhov tam sim no feem ntau nyob ib puag ncig 2-3%.
2. Yuav ua li cas cov khoom siv hluav taws xob ntawm lub raj LED tuaj yeem sib phim nrog lub teeb?
Ua ntej, peb yuav tsum ua tib zoo suav tus lej thiab cov kev sib txuas ua ke, thiab xaiv cov txheej txheem zoo tshaj plaws thiab kev sib txuas sib txuas. Qhov hluav taws xob thiab qhov tam sim no siv rau txhua LED yog tib yam, tab sis cov txiaj ntsig ntawm lub zog siv hluav taws xob tuaj yeem ua haujlwm tau zoo tshaj plaws. Txoj hauv kev zoo tshaj yog tsim cov txheej txheem thiab txheej txheem ua ntej thiab ua kom haum.
3. Dab tsi yog qhov tsim nyog tshaj plaws ua haujlwm tam sim no rau LED raj fais fab mov?
Feem ntau, qhov ua haujlwm tam sim no ntawm 2835 teeb hlaws LED yog 60 mA. Qee lub tsev tsim khoom siv nws thaum pib. Tus qauv tsim yog 60 mA. Tom qab ntau qhov kev ntsuas sib piv, nws yog qhov zoo tshaj los tsim 50-55 mA, thiab kev ua kom pom kev zoo yog qhov siab. , Tau kawg, siv cov roj teeb ua haujlwm siab. Kev suav yuav tsum yog raws lub zog ua haujlwm tau zoo. Cov khoom siv hluav taws xob ua haujlwm siab muaj qhov ua haujlwm siab luminous.
4. Dab tsi yog qhov ua haujlwm ntawm LED raj fais fab mov?
Qhov pom zoo ua haujlwm ntawm LED yog 3.0-3.4V. Tom qab ntsuas, lawv feem ntau ua haujlwm ntawm 3.125V, yog li cov lej suav ntawm 3.125V yog qhov tsim nyog dua. Tag nrho qhov hluav taws xob ntawm M teeb hlaws hauv kab=3.125*M. Feem ntau 12 hlua, qhov hluav taws xob yog 38v, 24 hlua, qhov hluav taws xob yog 74v
5. Yuav ua li cas dav yog qhov sib txuas sib txuas thiab qhov dav ntawm LED teeb lub rooj tsavxwm?
Txhawm rau ua kom lub teeb ci fluorescent LED ua haujlwm nyob rau ntau qhov sib txawv ntawm qhov hluav taws xob (tag nrho qhov hluav taws xob) AC85 ～ 265V, kev sib txuas ua ke ntawm LEDs ntawm lub teeb vaj huam sib luag yog qhov tseem ceeb heev.
Txawm li cas los xij, nrog kev nce qib ntawm cov khoom siv hluav taws xob LED teeb, nws feem ntau tuaj yeem ua tiav qhov hluav taws xob tag nrho. Qee qhov txiaj ntsig PF siab txog 0.98
6. Rau cov teeb hluav taws xob LED uas muaj cov khoom siv hluav taws xob, xyuam xim rau cov khoom siv hluav taws xob zoo. Kev pab lub neej yog 10,000 teev, thiab 105 degrees zoo dua.
