Dab tsi ntawm ib puag ncig yog LED cog teeb pom kev zoo tshaj plaws rau kev cog qoob loo?

Lub wavelength ntawm LED cog teeb yog heev haum rau cog kev loj hlob, flowering thiab fruiting.Feem ntau, cov nroj tsuag sab hauv tsev thiab paj yuav loj hlob zuj zus tuaj nrog lub sijhawm.Qhov laj thawj tseem ceeb yog qhov tsis muaj lub teeb irradiation.Lub teeb LED uas tsim nyog rau qhov xav tau ntawm cov nroj tsuag tuaj yeem tsis tsuas yog txhawb nqa lawv txoj kev loj hlob, tab sis kuj tseem txuas ntxiv lub sijhawm paj thiab txhim kho paj zoo.
Kev siv lub teeb pom kev zoo no rau kev ua liaj ua teb xws li tsev cog khoom, tsev cog khoom thiab lwm qhov chaw ntawm ib sab tuaj yeem daws qhov tsis zoo ntawm qhov tsis muaj hnub ci uas ua rau lub saj ntawm txiv lws suav, cucumbers thiab lwm yam zaub hauv tsev cog khoom kom poob, thiab Ntawm qhov tod tes, nws tuaj yeem ua ntej lub caij ntuj no tsev cog khoom solanum zaub.Nws yuav raug teev nyob ib ncig ntawm lub caij nplooj ntoos hlav Festival kom ua tiav lub hom phiaj ntawm kev cog qoob loo off-season.
Thaum tsav tsheb LED cog lub teeb los ntawm lub pob nyiaj tswj hwm, LED feem ntau ua rau AC ripple tam sim no thiab DC tam sim no ntawm inductor raws li kev xaiv tso zis lim.Qhov no yuav tsis tsuas yog nce RMS amplitude ntawm tam sim no nyob rau hauv LED, tab sis kuj nce nws hwj chim noj.Qhov no tuaj yeem ua rau qhov kub thiab txias thiab muaj kev cuam tshuam tseem ceeb rau lub neej ntawm LED.
Thaum nws qis dua qhov ntsuas hluav taws xob hloov hluav taws xob (qhov hluav taws xob tig ntawm qhov hluav taws xob ntawm LED dawb yog li 3.5V), qhov tam sim no dhau los ntawm LED yog qhov tsawg heev.Tshaj qhov pib no, qhov tam sim no nce exponentially nyob rau hauv daim ntawv ntawm ib tug pem hauv ntej voltage.Qhov no tso cai rau lub LED kom zoo li tus voltage qhov chaw nrog ib tug series resistor, nrog ib tug ceeb toom ceeb toom: cov qauv no tsuas siv tau nyob rau hauv ib tug ua hauj lwm DC tam sim no.Yog tias DC tam sim no nyob rau hauv LED hloov, ces qhov kev tiv thaiv ntawm tus qauv yuav tsum tau hloov tam sim ntawd kom muaj kev cuam tshuam cov kev khiav hauj lwm tshiab tam sim no.Nyob rau hauv ib tug loj rau pem hauv ntej tam sim no, lub hwj chim dissipation nyob rau hauv lub LED yuav sov lub ntaus ntawv, uas yuav hloov lub pem hauv ntej voltage poob thiab dynamic impedance.Nws yog ib qho tseem ceeb heev uas yuav tsum xav txog tag nrho cov cua kub dissipation ib puag ncig thaum txiav txim siab ntawm LED impedance.
Adjustable brightness yuav tsum tau ib tug tas mus li tam sim no tsav lub LED cog teeb, thiab tam sim no yuav tsum tau nyob twj ywm nyob rau hauv tsis hais lub input voltage.Qhov no yog qhov nyuaj dua li tsuas yog txuas lub teeb hluav taws xob rau lub roj teeb kom lub zog nws.
