LED cov ntxaij vab tshaus muaj ntau heev nyob rau hauv lub neej thiab coj ntau yam yooj yim rau peb lub neej.Txij li thaum lub teeb ci ntawm lub vijtsam LED tsis tuaj yeem hloov pauv nrog lub teeb pom kev nyob ib puag ncig, muaj teeb meem ntawm cov zaub tsis meej thaum nruab hnub lossis dazzling hmo ntuj vim yog ci dhau.Yog tias qhov ci tuaj yeem tswj tau, tsis tsuas yog lub zog tuaj yeem txuag tau, tab sis kuj tuaj yeem ua kom pom cov nyhuv ntawm lub vijtsam zaub tuaj yeem ua kom pom tseeb.
01led yog lub teeb ntsuab, nws lub ntsiab kom zoo dua yog siab luminous efficiency
Nrog rau txoj kev loj hlob thiab kev loj hlob ntawm cov ntaub ntawv science, lub luminous efficiency yuav zoo heev nyob rau hauv lub tom ntej no 10 xyoo;Kev siv hluav taws xob tsawg, lub neej ua haujlwm ntev, cov khoom siv rov ua dua tshiab, thiab tsis muaj kuab paug rau ib puag ncig.Txawm hais tias peb lub teb chaws pib lig, nyob rau xyoo tas los no nws kuj tau pib tshawb fawb thiab kev tsim kho thiab kev lag luam thiab kev txhawb nqa.Piv nrog rau lub teeb incandescent, LED muaj qhov sib txawv tseem ceeb: qhov ci ci ntawm lub teeb yog qhov sib piv rau qhov loj ntawm qhov tam sim no ntws los ntawm lub teeb-emitting diode.Siv cov yam ntxwv no, qhov ci ntsa iab ntawm ib puag ncig ib puag ncig yog ntsuas los ntawm qhov ntsuas qhov muag pom, lub teeb ci ntsa iab hloov pauv raws li qhov ntsuas tus nqi, thiab kev cuam tshuam ntawm qhov ci ntsa iab ntawm ib puag ncig ib puag ncig tau tswj hwm, thiab kev tsim kho hloov pauv tib neeg los ua haujlwm zoo siab.Qhov no tsis tsuas yog tsim kom muaj ib puag ncig zoo nrog qhov ci ntsa iab, tab sis kuj ua rau tag nrho kev siv lub teeb pom kev zoo thiab txuag lub zog.Yog li ntawd, kev tshawb fawb ntawm LED adaptive dimming technology yog qhov tseem ceeb heev.
02 lub hauv paus ntsiab lus
Qhov kev tsim no siv cov kem xa cov ntaub ntawv thiab kab scan txoj kev kom paub txog cov ntawv nyeem lossis duab LED.Txoj kev no yog ua ke nrog cov khoom siv hluav taws xob kom ua tiav lub hom phiaj ntawm cov teeb pom kev zoo tag nrho ntawm qhov screen.Siv cov yam ntxwv rhiab ntawm photoresistor rau ambient lub teeb, sau cov kev hloov ntawm ambient lub teeb, hloov mus rau hauv hluav taws xob teeb liab thiab xa mus rau ib tug-chip microcomputer, ib tug-chip processor ua teeb liab ua, thiab tswj lub luag hauj lwm piv ntawm cov zis. PWM yoj raws li txoj cai.Ib qho kev hloov hluav taws xob tswj hluav taws xob tau ntxiv ntawm ib qho-chip microcomputer thiab lub vijtsam coj ua kom paub txog kev hloov kho qhov ci ntawm lub vijtsam los ntawm ib qho-chip microcomputer.Kev hloov kho PWM nthwv dej yog siv los tswj cov kev hloov hluav taws xob hloov hluav taws xob hloov hluav taws xob los kho cov khoom siv hluav taws xob ntawm lub vijtsam zaub, thiab thaum kawg paub txog kev tswj qhov ci ntawm lub vijtsam.
03 Nta
Ib qho kev hloov kho qhov ci ci tswj xyuas rau lub teeb pom kev zoo diode zaub screen, uas yog tus cwj pwm los ntawm kev muaj xws li: lub luag haujlwm lub voj voog preset tus nqi nkag khoom, lub txee thiab qhov sib piv loj, nyob rau hauv lub txee thiab lub luag haujlwm lub voj voog preset tus nqi input ntaus ntawv feem suav tus nqi yog muab piv nrog tus nqi preset ntawm lub luag haujlwm lub voj voog mus rau qhov sib piv qhov loj los tswj tus nqi tso tawm ntawm tus sib piv.
04 LED adaptive dimming system kho vajtse tsim
Lub ci ci ntawm LED yog proportional rau tam sim no ntws los ntawm nws nyob rau hauv pem hauv ntej kev taw qhia, thiab qhov luaj li cas ntawm lub pem hauv ntej tam sim no tuaj yeem hloov kho qhov ci ci ntawm LED.Tam sim no, qhov ci ntsa iab ntawm LED feem ntau yog hloov kho los ntawm kev kho cov kev ua haujlwm tam sim no lossis hom mem tes dav hloov pauv.Cov qub muaj qhov hloov pauv loj, zoo linearity, tab sis siab zog noj.Yog li nws tsis tshua siv.Cov txheej txheem pulse width modulation siv ntau zaus los hloov cov leds, qhov hloov zaus yog dhau qhov ntau yam uas tib neeg tuaj yeem pom, kom tib neeg tsis hnov ​​​​qhov muaj nyob ntawm stroboscopic.Paub txog LED adaptive dimming.
