Dab tsi yog tag nrho -spectrum LED loj hlob teeb?

LED loj hlob teebtechnology yog qhov tsis ntev los no. Ib qho ntawm nws cov txiaj ntsig yog lub peev xwm los tsim kom muaj ntau qhov sib txawv ntawm emission spectra.
Kab lus no tshuaj xyuas lub ntsiab lus ntawm tag nrho spectrum LED loj hlob lub teeb thiab nws cov txiaj ntsig rau kev loj hlob ntawm tsob ntoo.

Yuav ua li cas yog ib tug paLED loj hlob teebspectrum?

Lub teeb pom kev zoo LED loj hlob feem ntau siv cov xim xiav thiab liab LEDs. Pinkish- lub teeb liab liab tawm qhia tias kev sib xyaw ntawm xiav thiab liab.
Ib txwmLED loj hlob teebsiv qhov sib xyaw no vim tias cov nroj tsuag ua cov photosynthesis zoo tshaj plaws hauv thaj tsam xiav thiab liab ntawm spectrum.
Qhov spectrum no kom meej meej tsuas yog ib feem me me ntawm tag nrho cov spectrum pom. Qhov no yog undoubtedly nyob deb ntawm qhov peb yuav xaiv raws li tag nrho spectrum.
Feem ntau, cov teeb pom kev loj hlob no siv monochrome LEDs, uas yog xiav LED thiab liab LED. Kev faib hluav taws xob spectral, piv txwv li hauv qab no, feem ntau muab cov ntaub ntawv no.
Txawm li cas los xij, yog tias lub teeb xiav thiab liab yog qhov zoo rau photosynthesis, qhov tseem ceeb ntawm lwm cov wavelengths yog dab tsi?
Lwm yam tseem ceeb cuam tshuam cov nroj tsuag kev noj qab haus huv thiab lub zog tshaj qhov tsuas yog cov photosynthesis. Thaum kawg, qhov no yuav ua rau cov qoob loo zoo dua, txhim kho kev zoo nkauj, lossis nce cov khoom noj ceev. Hauv lwm lo lus, kev ua tau zoo hloov pauv tsuas yog kom muaj nuj nqis.

Ib tug meej txhais ntawm tag nrho cov spectrumLED loj hlob teeb pom kev zoo

Kev tshawb fawb ntau heev yuav tsum tau ua; Txawm li cas los xij, nce kev sim thiab cov txiaj ntsig kev tshawb fawb qhia tau tias cov nroj tsuag muaj txiaj ntsig zoo nyob rau hauv qhov sib npaug spectrum.
Qhov tshwm sim no tej zaum yuav elucidated los ntawm evolution ntawm cov nroj tsuag los siv tej yam ntuj tso tshav ntuj tsis tau tsuas yog raws li ib qho chaw ntawm sustenance tab sis kuj yog ib tug teeb liab rau cov txheej txheem xws li blooming thiab fruiting.
Yog li ntawd, lub ntsiab txhais ntawm tag nrho cov spectrum yuav encompass ib tug ntau yam ntawm hluav taws xob los ntawm ultraviolet mus infrared, zoo li lub hnub ci ntuj.
Ib lub teeb ci uas nthuav tawm cov spectrum no feem ntau tshwm dawb.
Puas yog qhov emission ntawm lub teeb dawb los ntawm ib qho LED loj hlob lub teeb inherently cais nws raws li ib tug tag nrho spectrum loj hlob teeb?
Cov lus teb tsis zoo, thiab peb yuav piav qhia txog qhov no hauv ntu tom ntej.

Muaj ntau txoj hauv kev los tsim lub teeb dawb

Nyob rau hauv sib piv rau cov paLED loj hlob teebtxoj hauv kev siv xiav thiab liab monochromatic LEDs, tag nrho spectrum loj hlob teeb feem ntau suav nrog phosphor txheej.
Lub phosphor txheej txhim kho tag nrho cov spectrum loj hlob teeb los ntawm kev hloov lub teeb los ntawm ib qho kev txwv wavelength ntau yam (piv txwv li, 460 nm xiav) rau hauv qhov dav dav ntawm lub wavelengths ntev dua (xws li 600 - 700} nm liab).
Txheej xiav LED nrog kev sib xyaw ntawm ntsuab, daj, thiab / lossis liab phosphors ua rau muaj kev tiv thaiv dav dua ntawm qhov pom spectrum.
Phosphors emit lub teeb hla ntau lub wavelengths, ua kom muaj kev sib haum xeeb ntawm cov xim uas ua rau lub teeb dawb.
Lub emission ntawm lub teeb dawb los ntawm ibLED loj hlob teebtsis yog qhov qhia tau hais tias nws yog qhov tseeb tag nrho spectrum teeb qhov chaw.
Ib txoj hauv kev ua tau zoo yog los ntsuas nws cov xim rendering Performance index (CRI). Qhov kev txheeb xyuas no muaj txiaj ntsig vim nws qhia qhov zoo sib xws rau ntuj tshav ntuj. Tus nqi zoo tshaj CRI qhia tau hais tias lub teeb ci zoo ib yam li lub hnub ci ntuj, suav tias yog qhov zoo tshaj plaws, tag nrho - spectrum lub teeb ci.
