Ntawm Semiconductor tau tshaj tawm NCL31000 thiab NCL31001 LED tsav tsheb ICs uas yuav yooj yim rau kev txhim kho cov teeb pom kev zoo hauv lub xeev (SSL) cov khoom lag luam nrog kev sib txuas thiab cov teeb pom kev ntse ntse. Cov ntawv thov muaj peev xwm tus tsav tsheb ICs yuav txhawb nqa ntau yam rau Internet ntawm Yam (IoT) daim ntawv thov suav nrog kev tso chaw sab hauv tsev thiab pom kev sib txuas lus (VLC). Ntxiv mus, ob lub ICs tuaj yeem ua ke rau hauv ntau qhov kev tsim kho luminaire txhawm rau txhawb nqa spectral tuning xws li tunable dawb mus rau tag nrho cov xim muaj peev xwm.
Ua ntej, ua ntej peb mus rau cov yam ntxwv siab heev ntawm tus tsav tsheb tshiab IC khub, cia peb tham txog qhov zoo ntawm lub teeb thiab lub hauv paus kev ua haujlwm xws li dimming. Raws li peb tau sau ntau zaus, kev lag luam SSL tau hloov zuj zus mus rau theem uas qhov zoo yuav tsum dhau ntawm cov peev txheej qub qub. Cov khoom tshiab On Semiconductor feature ib lub pob tsav tsheb thiab tuaj yeem ua haujlwm los ntawm cov khoom siv hluav taws xob ntawm 21.5-57V. Cov neeg tsim khoom tuaj yeem xaiv qhov hloov pauv zaus hauv 44.4-kHz-1-MHz ntau yam. Cov ICs tuaj yeem siv cov kab hluav taws xob los yog cov hloov pauv hloov pauv hloov pauv (PWM) dimming schemes txhua txoj hauv kev kom tawm nrog 0.1% qhov tseeb.
ICs muaj ntau yam kev tiv thaiv hluav taws xob uas tuaj yeem cuam tshuam nrog qhib lossis luv. Muaj kev tiv thaiv kub dhau thiab kev kuaj mob ua haujlwm xws li kev saib xyuas tam sim no thiab qhov hluav taws xob. Cov neeg tsav tsheb ICs kom meej meej txhawb kev ua tau zoo thiab kev ntseeg tau.
Tam sim no cia peb tig mus rau kev sib txuas cov yam ntxwv thiab ntau tus qauv tsim. Cov luminaire txuas nrog ib txwm pom tseeb xav tau qee yam kev txhawb nqa network thiab feem ntau cov khoom lag luam zoo li no suav nrog kev txhawb nqa rau cov sensors thiab lwm yam khoom siv uas tuaj yeem ua kom muaj teeb pom kev zoo thiab IoT daim ntawv thov.
Kev txhim kho ntawm lub teeb ci ntse feem ntau pib nrog lub microcontroller (MCU). Ntxiv rau DC-DC phaw converter uas ua rau lub teeb ci LED lub cav, NCL31000 integrates ob qhov ntxiv DC-DC converters, thawj qhov uas tso tawm 3V rau lub hwj chim MCU lossis lwm yam hluav taws xob qis. Qhov thib ob yog qhov hloov kho 2.5-24V converter uas tuaj yeem siv hluav taws xob sensor thiab kev sib txuas lus subsystems. NCL31001 tsuas yog suav nrog 3V converter. Tus tswv cuab thib ob ntawm tus tsav tsheb IC series yuav raug siv ntxiv rau NCL31000 hauv ntau qhov channel, tunable tsim qhov twg lub luminaire tsuas xav tau ib txheej ntawm sensor thiab kev sib txuas ua haujlwm.
NCL31000 architecture yuav txhawb nqa tag nrho cov kev sib txuas- teeb pom kev zoo uas peb tau npog hauv peb nplooj ntawv. "Muaj kev xav tau ntau ntxiv rau cov teeb pom kev zoo li LED luminaire cov tuam txhab paub txog yuav ua li cas cov yam ntxwv no txhim kho yooj yim rau cov neeg siv thaum txo cov nqi khiav lag luam thiab kev siv hluav taws xob," said Michel De Mey, tus lwm thawj, Industrial Solutions ntawm On Semiconductor. Los ntawm kev txhawb nqa cov yam ntxwv no nrog rau kev ua lag luam ua tau zoo thiab kev ua haujlwm, NCL31000 thiab NCL31001 yuav qhib ntau lub sijhawm tshiab rau cov teeb pom kev zoo. "
Lub On Semiconductor thov hais txog kev txhawb nqa VLC, txawm li cas los xij, yog dab tsi tiag tiag teeb tsa tus tsav tsheb tshiab ICs sib nrug los ntawm cov khoom lag luam hauv khw. Lub tuam txhab tau hais tias kev hloov pauv bandwidth nyob ib puag ncig 50 kHz hauv tus tsav tsheb ua rau VLC ua haujlwm. Tsis tas li ntawd, lub tuam txhab tau hais tias cov cuab yeej yuav txhawb nqa VLC sab hauv qhov chaw nyob nrog 30-cm raug. Peb tsis tau them rau qhov chaw nyob sab hauv tsev ntau li lig, tab sis ntau tus neeg tseem ntseeg tias nws yuav dhau los ua daim ntawv thov IoT tseem ceeb uas txuas nrog SSL systems tuaj yeem tuav.
Peb yuav nco ntsoov tias tus tshiab On Semiconductor tsav ICs tsis koom nrog cov txheej txheem tshiab tshaj plaws rau kev sib txuas lus intra-luminaire ntawm cov tsav tsheb thiab lwm cov subsystems. Lub DALI-2-enabled D4i interface tau dav siv nyob rau hauv LED tsav tsheb npaj rau kev xa mus rau kev sib txuas-SSL cov xwm txheej. Tus tsim khoom SSL tuaj yeem xaiv MCU uas suav nrog D4i interface lossis ntxiv nws ua ib qho kev sib cais. Tab sis ntau D4i-raws li kev tsim ua ke ua ke tswj kev tswj hwm thiab kev ua haujlwm sensor hauv ib qho kev sib cais uas txuas ncaj qha mus rau D4i-enabled tsav tsheb.
