Qhov sib txawv ntawm cov nroj tsuag coj loj hlob teeb thiab cov teeb pom kev zoo

1. Cov teeb pom kev zoo
Lub teeb incandescent yog lub teeb hluav taws xob hluav taws xob uas ua kom muaj zog thiab ua kom sov cov filament mus rau lub xeev incandescent, thiab emits pom lub teeb los ntawm kev siv hluav taws xob thermal. Lub teeb xim thiab lub teeb sau kev ua tau zoo ntawm lub teeb incandescent yog qhov zoo heev, tab sis vim yog lub teeb pom kev zoo, nws tau maj mam thim tawm ntawm kev tsim khoom thiab muag. Nws qhov zoo yog cov qauv yooj yim, tus nqi qis, siv yooj yim thiab zoo ci. Qhov tsis zoo yog qhov ua haujlwm qis luminous thiab lub neej ua haujlwm luv.



2. Tungsten halogen teeb
Lub teeb tungsten halogen yog ib hom teeb uas muaj cov roj halogenated hauv lub teeb. Nyob rau hauv tej yam kev mob kub, cov tungsten thiab halogen zoo li cov khoom evaporated ntawm ib tug haum qhov kub thiab txias yuav reacts, thiab ces ib hom Volatile halogen tungsten tebchaw. Lub sijhawm no, halogen tungsten compounds nyob rau hauv lub xeev gaseous. Thaum lub xeev no gaseous rhuab, nws yuav volatilize mus rau hauv tungsten thiab halogen, thiaj li hais tias lub teeb yuav recycled. Qhov tsis zoo yog kev poob siab tsis zoo.



3. Cov teeb fluorescent
Cov teeb fluorescent siv cov mercury vapor los tsim cov paug tawm hauv qhov kev txiav txim ntawm qhov kev siv hluav taws xob, uas tso tawm me ntsis pom lub teeb thiab ntau ntawm ultraviolet rays. Cov kab hluav taws xob ultraviolet txhawb cov fluorescent hmoov coated rau ntawm phab ntsa sab hauv ntawm lub raj kom nws tawm lub teeb ci. Lub neej ntev thiab ci ntsa iab ntawm cov teeb fluorescent zoo dua li cov teeb ci incandescent. Qhov tsis zoo yog lub sijhawm pib ua haujlwm ntev, stroboscopic flicker yuav tshwm sim, cuam tshuam rau lub neej kev pabcuam. Yog tias lub teeb fluorescent tsis zoo, kev puas tsuaj rau tib neeg qhov muag yuav loj dua.



4. LED cog kev loj hlob teeb
LED yog lub teeb-emitting diode. Qhov zoo ntawm kev ua haujlwm siab, ntshiab lub teeb xim, tsis muaj zog noj; Lub neej ntev ntev, kev nyab xeeb thiab kev tiv thaiv ib puag ncig, pib tam sim; kev co kuj, lub teeb txias qhov chaw, lub sij hawm ntev lub teeb lub cev nto nrog tsis tshua muaj cua sov thiab zoo tshav kub dissipation. Mus ze ntawm qhov khoom yam tsis muaj qhov kub. Raws li qhov tshwj xeeb no, LED tuaj yeem muab tso rau hauv kab rov tav lossis ntsug saum cov nroj tsuag.



Photosynthesis
Qhov laj thawj tseem ceeb yog vim li cas cov teeb pom kev loj hlob siv cov teeb tshwj xeeb yog lub teeb uas xav tau rau cov nroj tsuag photosynthesis txawv ntawm lub teeb uas peb siv rau txhua hnub teeb pom kev zoo. Kev loj hlob ntawm cov nroj tsuag yuav tsum tau siv lub hnub lub teeb lub zog los sib xyaw cov pa roj carbon dioxide thiab dej los tsim cov organic teeb meem thiab tso tawm oxygen. Cov txheej txheem no hu ua photosynthesis.



Cia peb saib cov teebmeem ntawm cov wavelengths sib txawv ntawm cov nroj tsuag:
280-315nm: Qhov cuam tshuam ntawm morphology thiab physiological txheej txheem yog tsawg.
315-400nm: Tsawg dua chlorophyll nqus, cuam tshuam cov nyhuv Photoperiod, thiab tiv thaiv qia elongation.
400-520nm(Blue): Chlorophyll thiab carotenoids nqus feem ntau hauv kev faib ua feem thiab muaj feem cuam tshuam loj tshaj plaws ntawm photosynthesis.
520-610nm(Green): Tus nqi nqus ntawm cov xim tsis siab.
610-720nm(Liab): Qhov nqus ntawm chlorophyll yog qhov tsawg, uas muaj qhov cuam tshuam tseem ceeb ntawm photosynthesis thiab cov nyhuv photoperiod.
720-1000nm: Tsawg nqus tau, txhawb lub cell txuas ntxiv, cuam tshuam rau paj thiab noob germination.
>1000nm:720-1000nm: Hloov ua cua sov.

Los ntawm cov ntaub ntawv saum toj no, lub wavelength ntawm lub teeb xav tau rau cov nroj tsuag photosynthesis yog hais txog 400-720nm. Lub 400-520nm (xiav) lub teeb thiab 610-720nm (liab) pab txhawb ntau tshaj plaws rau photosynthesis. 520-610nm (ntsuab) lub teeb muaj qhov nqus tsis zoo ntawm cov xim cog.

Nws tuaj yeem pom tau tias cov teeb pom kev cog qoob loo yog tsim los ua xim liab thiab xiav ua ke, tag nrho xiav thiab tag nrho liab los muab lub teeb ntawm ob lub wavelengths ntawm liab thiab xiav, npog lub wavelength ntau yam uas yuav tsum tau rau photosynthesis. Hauv kev pom cov nyhuv, cov xim liab thiab xiav ua ke ntawm cov teeb pom kev zoo li liab.

Thaum LED cog ntxiv lub teeb muab cog teeb pom kev zoo, lub zog dav dav yog tsawg dua 50w, rau cov nroj tsuag sib txawv, qhov siab ntawm lub ntsiab nplooj ntawm cov nroj tsuag yuav tsum yog 0.2-0 .8m ib. Lub zog siab dua 50w, rau cov nroj tsuag sib txawv, qhov siab ntawm nplooj nplooj loj ntawm cov nroj tsuag yuav tsum yog 0.5-1.5 meters. Hauv cov ntsiab lus, LED teeb yog cov teeb pom kev zoo tshaj plaws rau cov nroj tsuag teeb pom kev zoo.
