Kuv puas tuaj yeem siv lub teeb xiav thiab liab LED los cog tsob ntoo?
Cov lus teb luv luv yog tsis muaj. Thaum lub teeb xiav thiab liab LED feem ntau siv rau hauv kev cog qoob loo, tsis yog txhua lub teeb xiav thiab liab LED yog tsim rau cov nroj tsuag loj hlob. Lub wavelength thiab kev siv ntawm lub teeb yog qhov tseem ceeb rau kev loj hlob ntawm cov nroj tsuag.
Ua ntej thiab qhov tseem ceeb, lub teeb spectrum yog qhov tseem ceeb rau kev loj hlob cov nroj tsuag zoo. Chlorophyll, cov xim uas nqus lub teeb thiab muab lub zog rau cov nroj tsuag kev loj hlob, muaj qhov sib txawv nqus peaks rau ntau lub wavelengths nyob rau hauv lub teeb pom kev zoo. Lub teeb xiav thiab liab yog ob lub ntsiab wavelengths siv rau kev loj hlob ntawm cov nroj tsuag vim lawv sib haum mus rau lub ncov ntawm chlorophyll nqus. Yog li ntawd, qhov zoo tshaj plaws ntawm xiav thiab liab LED lub teeb rau cov nroj tsuag loj hlob yog cov uas emit tshwj xeeb wavelengths uas phim lub nqus peaks ntawm chlorophyll.
Qhov kev siv ntawm lub teeb yog lwm qhov tseem ceeb. Cov nroj tsuag xav tau ib qho tshwj xeeb ntawm lub teeb lub zog rau photosynthesis. Lub teeb me me dhau thiab cov nroj tsuag yuav tsis loj hlob zoo, thiab lub teeb ntau dhau tuaj yeem ua rau cov nroj tsuag puas. Qhov kev siv ntawm lub teeb yog ntsuas raws li Photosynthetic Photon Flux Density (PPFD), uas yog hais txog tus naj npawb ntawm photons ntawm lub teeb uas poob rau ntawm thaj chaw muab, feem ntau ntsuas hauv micromoles ib square meter ib ob (umol / m² / s). Yog li ntawd, nws yog ib qho tseem ceeb uas yuav tau xaiv LED loj hlob teeb nrog tsim nyog PPFD qhov tseem ceeb rau koj cov nroj tsuag tshwj xeeb thiab theem kev loj hlob.
Tsis tas li ntawd, qhov zoo thiab kav ntev ntawm LED chips lawv tus kheej kuj tseem ceeb rau kev loj hlob ntawm cov nroj tsuag. Pheej yig thiab tsis zoo LED teeb yuav sai sai degrade, txo qhov kev siv thiab spectrum ntawm lub teeb xav tau los ntawm cov nroj tsuag. Yog li ntawd, xaiv cov chips zoo LED los ntawm cov tuam txhab muaj npe nrov yog qhov tseem ceeb.
Hauv kev xaus, thaum lub teeb xiav thiab liab LED yog qhov tseem ceeb rau kev loj hlob ntawm cov nroj tsuag, tsis yog txhua hom xiav thiab liab LED teeb yog tsim rau cov nroj tsuag loj hlob. Kev tsim nyog wavelength, siv, thiab LED nti zoo yog txhua yam uas yuav tsum tau xav txog thaum xaiv LED teeb rau cog kev loj hlob. Los ntawm kev xaiv lub teeb pom kev zoo LED, koj tuaj yeem txhim kho koj cov nroj tsuag kev loj hlob zoo dua thiab zoo.
