Cov txheej txheem cog txiav txim siab qhov tsim spectral. Kev tsim thiab tsim cov teeb pom kev zoo yog los xyuas kom meej qhov ua tau zoo ntawm lub teeb zoo uas yuav tsum tau ua los ntawm cov txheej txheem cog. Cov yam ntxwv ntawm cov teeb pom kev loj hlob no txiav txim siab qhov nyuaj thiab ntau haiv neeg ntawm cov nroj tsuag spectral tsim.
Loj hlob Lub Teeb cuam tshuam rau PPFD qhov tseem ceeb
Feem ntau, cov txheej txheem cog qoob loo yuav tsum tau tshaj tawm cov hluav taws xob niaj hnub raws li qee qhov teeb pom kev zoo, lossis PPFD tus nqi ntawm qhov chaw cog (qee qhov kev cog qoob loo yuav tsum muaj YPFD qhov tseem ceeb) thiab lub sijhawm photoperiod, uas txiav txim siab PPFD tus nqi thiab photoperiod, thiab tus tsim qauv. raws li tus nqi PPFD. Xam tus nqi PPF (lossis YPF tus nqi) ntawm LED qhov chaw ua ntej ua spectral tsim.
Nws yuav tsum tau muab sau tseg ntawm no hais tias nyob rau hauv tib lub teeb qhov chaw PPF tus nqi, txawv lub teeb tis tsim, tshav kub dissipation tsim thiab tsav tsim ua rau muaj kev sib txawv tseem ceeb nyob rau hauv PPFD qhov tseem ceeb. Cov txheej txheem tsim khoom muaj kev cuam tshuam zoo rau kev siv hluav taws xob zoo ntawm kev loj hlob lub teeb. Cov nyhuv no tuaj yeem siv tau. Qhov siab dua tus nqi ntawm PPF thiab PPFD ib watt ntawm hluav taws xob fais fab, qhov zoo dua.
Thaum tham txog Grow Light spectrum, tsuas yog qhov tsim nyog tshaj plaws yog qhov zoo tshaj plaws.
Vim tias lub spectrum ntawm LED loj hlob lub teeb tuaj yeem tsim tau, lub spectrum qhia ntau haiv neeg. Lub spectrum ntawm txhua lub teeb pom kev zoo tshaj plaws yog tshaj tawm los ntawm tus tsim qauv. Ntawm no peb qhia meej tias qhov zoo tshaj plaws spectrum yog qhov zoo tshaj plaws. Ib qho kev cog qoob loo, sim ua kom lub LED spectrum universal tsis yog ib lub tswv yim tsim zoo, thiab kev sib raug zoo siab spectrum tsim yog nyob ntawm tus nqi ntawm kev cog qoob loo thiab nkim zog.
Tsom ntsoov rau qhov ua tau zoo ntawm cov nroj tsuag teeb
Lub luminaire efficiency ntawm cov nroj tsuag teeb yog qhov piv ntawm PPF tus nqi ntawm lub luminaire rau PPF tus nqi ntawm lub teeb qhov chaw. Tus nqi no tsawg dua 1, uas muaj feem xyuam rau qhov kev tsim kho qhov muag thib ob. Qhov ua tau zoo ntawm LED loj hlob lub teeb luminaire feem ntau yog nyob nruab nrab ntawm 0.9 thiab 0.5, thiab cov luminaire efficiency cuam tshuam cov nroj tsuag. Lub zog noj Performance index thiab cog efficiency ntawm lub teeb, qhov efficiency ntawm cov nroj tsuag teeb nrog lens tsim yuav tsis ntau tshaj 0.8.
Hais txog spectral ratio
Txog tam sim no, ntau lub teeb loj hlob tseem siv qhov sib piv ntawm nti hauv ntau yam spectrum thaum tham txog qhov piv ntawm spectral. Txij li thaum lub nti piv tsis tuaj yeem cuam tshuam cov hluav taws xob hluav taws xob, qhov teeb meem no yuav tsum nkag siab txog cov lus qhia tshwj xeeb ntawm LED nti. LED nti yog raws li tib lub nti loj. Lub zog radiant yog categorized thiab muab. LED spectrum muab los ntawm cov nti piv yuav muaj 30 feem pua ntawm qhov sib txawv, uas yog ib qho ntawm cov laj thawj rau qhov sib txawv ntawm cov nyhuv ntawm cov khoom sib txawv ntawm tib yam khoom.
