Qhov teeb meem ci ntsa iab ntawm sab nraum zoov puv xim LED zaub ncaj qha cuam tshuam rau tus kheej kev nyab xeeb ntawm cov neeg tsav tsheb thiab cov neeg taug kev, thaum lub teeb ci sab nraum zoov puv xim LED tuaj yeem ua rau cov neeg taug kev lub qhov muag tsis xis nyob, ua rau khaus qhov muag, thiab cuam tshuam rau kev tsav tsheb nyab xeeb. Yuav daws qhov teeb meem no li cas?
Nws tuaj yeem raug txheeb xyuas ncaj qha los ntawm qhov ci ntawm sab nraum zoov puv xim LED zaub. Cov kev daws teeb meem hauv qab no tuaj yeem daws qhov teeb meem ntawm qhov ci ntsa iab ntau dhau ntawm sab nraum zoov puv xim LED zaub, thiab kho qhov ci thiab xim ntawm cov xim sab nraum zoov puv xim LED.
Sab nraum zoov puv xim LED zaub
Ua ntej, kho qhov ci.
1. Hloov tam sim no ntws los ntawm LED. Feem ntau, kev ua haujlwm tsis tu ncua ntawm LED raj yog li 20 mA. Tsuas yog rau qhov saturation ntawm LED liab, lub ci ci ntawm lwm cov LEDs yog qhov sib piv rau qhov ntws tam sim no.
2. Pulse width modulation (PWM): Siv cov zaus hloov pauv uas tib neeg lub qhov muag tuaj yeem pom tau, kev tswj hwm grey yog pom tau los ntawm kev hloov pauv mem tes dav, uas yog, lub teeb mem tes dav (uas yog, lub voj voog lub luag haujlwm) hloov pauv raws sijhawm, tsuav yog lub teeb rov ua dua Yog tias lub sijhawm luv txaus (uas yog, tus nqi refresh yog siab txaus), tib neeg lub qhov muag yuav tsis xav tias lub teeb-emitting pixels yog co. Pulse width modulation yog dav siv vim nws tsim nyog rau kev tswj digital. Txoj kev siv feem ntau yog siv lub microcomputer los muab LED zaub. Feem ntau ntawm cov ntxaij vab tshaus LED uas twb muaj lawm siv pulse width modulation technology los tswj lawv cov qib grey.
Qhov thib ob, kev hloov xim.
Sab nraum zoov tag nrho-xim LED zaub cov khoom kho cov xim ntawm tag nrho cov tshuaj ntsuam raws li liab, ntsuab, thiab xiav brightness ntawm LED teeb. Lub tuam txhab txiav txim siab cov xim siv raws li qhov ci ntsa iab ntawm peb xim liab, ntsuab, thiab xiav ntawm cov khoom xaiv. Feem ntau, qhov qis qis qis yog siv los ua cov xim siv. Thaum cov xim siv tau mus txog qhov ci siab tshaj plaws, nws tuaj yeem siv rau lwm yam (ob xim) lossis Ob hom (xim tag nrho) raug kho. Thaum cov zaub yog ob-xim, feem ntau, ntsuab yog siv los kho qhov ua hauj lwm tam sim no ntawm diode liab. Feem ntau nws yog los txo qhov kev khiav hauj lwm tam sim no, thiab kho tus qauv kom sib npaug ntawm cov xim daj, uas yuav txo qhov ci ntsa iab ntawm tag nrho sab nraum zoov puv xim LED zaub. Kho cov xim ntawm sab nraum zoov puv xim LED zaub rau qhov zoo tshaj plaws tshuav nyiaj li cas yuav ua rau lub brightness ntawm lub vijtsam yuav txo. Yog tias sab nraum zoov puv xim LED zaub screen ua tiav qhov siab tshaj plaws ntawm txhua xim kom ua tau raws li qhov yuav tsum tau ua kom pom kev ci ntsa iab, cov xim sib npaug yuav ploj. Piv txwv li, lub daj nyob rau hauv ob-xim screen yog reddish los yog ntsuab.
Kuv vam tias yav tom ntej, cov tuam txhab ua lag luam sab nraum zoov ntau xim LED tuaj yeem tswj qhov ci ntsa iab ntawm tib neeg lub qhov muag thaum tsim thiab tsim cov khoom lag luam LED, kom cov ntxaij vab tshaus LED tuaj yeem ua tau zoo, noj qab haus huv thiab sai dua. Kev tsim kho av.
Tom ntej: LED zaub manufacturers: LED zaub lub zog txuag lub tswv yim
