Agricultural LED teeb pom kev zoo siv lub tshuab tsav tsheb tsis muaj AC.
Cov tuam txhab xws li Ib zaug Innovations tau nce qib nrog lub zog-npaum LED-raws li kev ua liaj ua teb teeb pom kev zoo uas txhim kho tsiaj kev noj qab haus huv thiab ua kom cov khoom tsim tau zoo ntawm tus nqi qis, tsis hais txog cov txheej txheem kev ua haujlwm thiab kev txhawb nqa rov qab.
Thaum cov cuab yeej cuab tam siv cov xim sib xyaw ua ke los muab cov xim monochromatic los txhawb cov liab thiab ntsuab thiab ua kom muaj kev sib haum xeeb, kho tau, dimmable lub teeb thoob plaws tag nrho cov spectrum, nws yuav outperform generic dawb LED technology (Fig. 1 ntawm no). Cov tsoos RGB arrays siv hauv cov lus qhia yog siv los ntawm pulse-dav modulated DC pulses; Lub luag haujlwm lub voj voog ntawm DC pulses yog hloov kho los tswj lub sijhawm tig rau txhua lub LED. Nyob rau hauv sib piv, AgriShift ncaj qha tsav nws LEDs siv ib tug patented stepped AC voltage. Txoj kev no txuag nyiaj thiab qhov chaw thaum txhim kho kev cia siab vim nws tsis xav tau AC / DC hloov-hom tsav tsheb lossis EMI lim. Vim qhov tseeb tias txhua tus noog, suav nrog cov noog, tshwj xeeb tshaj yog rau cov suab nrov EMI, txoj kev qis-EMI yog qhov tseem ceeb sib npaug los ntawm qhov pom ntawm tsiaj txhu.
Cov khoom lag luam AgriShift's AC thev naus laus zis yog qhov tshwj xeeb hauv qhov uas nws siv qhov ncaj nraim analog architecture kom ua tiav lub hom phiaj nyuaj. Lub circuitry tshem tawm qhov kev xav tau rau cov kev hloov pauv digital nyuaj los ntawm kev sib txuas ua ke LEDs ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab txuas nrog tus tswv hloov FET. Qhov no tso cai rau nws muab qhov tsim nyog tsav tam sim no waveforms yam tsis xav tau cov cuab yeej zoo li no. Hauv qhov tseem ceeb, LEDs teb rau qhov muab AC voltage los ntawm kev tsim lawv tus kheej yoj tam sim no. Cov xim spectrum tuaj yeem hloov kho los ntawm kev hloov kho hom LEDs hauv txhua txoj hlua (siv cov xim monochromatic xim thiab cov LEDs dawb) thiab siv ntau qhov chaw voltage. Siv cov pa dimming technologies, qhov kev tsim no ua rau nws yooj yim los tsim lub teeb xim hloov xim. Nws tseem tsis tau nrog qhov sib txawv ntawm DC tswj circuitry uas cov xim hloov teeb pom kev zoo tau ua haujlwm feem ntau. Cov teeb pom kev teeb pom kev zoo ua haujlwm seamlessly nrog kev tswj cov teeb pom kev hauv tsev tam sim no, ua rau kev hloov pauv mus rau cov thev naus laus zis tshiab yooj yim rau cov neeg ua liaj ua teb.
Ntxiv rau hom hnub sawv / hnub poob uas hloov cov spectrum mus rau xim liab raws li lub teeb ci, AgriShift teeb yuav dimmed ntawm 2 feem pua rau 100 feem pua. Lub teeb tsim ua tiav spectrum uas tsis muaj fading, uas yog zoo meej rau kev txhawb nqa kev loj hlob thoob plaws hauv cov theem thaum ntxov ntawm kev loj hlob qaib (brood teeb pom kev zoo). Blues, zaub ntsuab, thiab cov liab liab tuaj yeem tshwm sim los txhawb cov leeg nqaij thaum loj hlob, txawm tias dimming yuav raug txo mus rau 30 feem pua. Tag nrho dimming yog siv rau lub hli, thiab monochromatic xiav yog siv los soothe hens, txwv tsis pub lawv hnyav pub noj, thiab ua kom ntes tau yooj yim dua. Cov spectral hloov ntawm dawb mus rau monochrome uas tshwm sim thaum ib tug raug triac dimmer yog siv los dim ib tug AgriShift VOBF (Variable Output Broiler Fixture) qaib lub teeb yog qhia nyob rau hauv daim duab 2.
AgriShift teeb siv tsuas yog 2-14W thiab tsim 200-950 lm nrog tsawg dua 20 feem pua ntawm tag nrho cov kev sib haum xeeb distortion thiab muaj zog tshaj li 97 feem pua. (THD). Lwm qhov txiaj ntsig ntawm analog AC tsim, uas muaj kev hloov pauv tau yooj yim thiab tswj cov kev cuam tshuam ib ntus, yog nws qhov qis THD. Nyob ntawm tus tsiaj tus cwj pwm tau hais txog, tus kheej lub teeb yuav raug teeb tsa nrog ntau yam ntawm LEDs, cov qauv tsim, thiab cov khoom siv hluav taws xob.
