Qhov tseem ceeb tshaj plaws nyob rau hauv cov haujlwm tseem ceeb ntawm cov nroj tsuag yog qhov pom kev pom tseeb, txij li rau lawv lub teeb ua haujlwm ua lub hauv paus ntawm lub zog. Ua tsaug rau qhov pom kev, cov nroj tsuag tig dej thiab carbon dioxide rau hauv carbohydrates. Raws li qhov tshwm sim no, qhov tsim ntawm lawv cov ntaub so ntswg tshwm sim, thiab cov txheej txheem metabolic tshwm sim.
Txawm li cas los xij, rau qhov ua tiav cov kev ua tiav ntawm cov muaj zog seedlings, ntxiv rau qhov ntau ntawm lub teeb, nws lub sijhawm thiab lub teeb pom kev kuj tseem ceeb.
Los ntawm kho lub sijhawm ntev ntawm nruab hnub, nws muaj peev xwm ua tiav zoo rau tag nrho cov txheej txheem ntawm kev loj hlob thiab kev loj hlob ntawm cov noob ntoo.
Qhov feem cuam ntawm lub teeb ci ntawm LED teeb txawb ntawm kev txhim kho cov yub
Lub teeb pom kev cuam tshuam cov kev loj hlob ntawm cov nroj tsuag hauv ntau txoj kev.
Cov khoom siv LED rau cov nroj tsuag tsim cov duab liab hauv cov xim liab thiab xiav. Nws yog cov duab hluav taws xob uas xav tau ntau tshaj plaws rau kev yub, vim lawv pab txhawb lawv txoj kev vam meej.
Hauv tshwj xeeb, cov xim xiav xiav ua kom lub hauv paus loj hlob, liab muaj cov txiaj ntsig zoo rau kev tsim tawm tag nrho ntawm cov noob. Cov xim xws li daj lossis ntsuab yog tsis yog nqus los ntawm cov nroj tsuag.
Lub wavelength ntawm lub teeb uas yuav tsum tau rau lub teeb meem hluav taws xob ua kom sib txawv yog txawv ntawm lub teeb yoj hluav taws xob los ntawm lub teeb ci uas tsis sib xws, lub phyto-efficiency uas yog qhov tsawg heev. Yog li ntawd, tau txais, nws zoo li, ntau lub teeb, nroj tsuag tiag tiag ua nws tsis muaj.
Yeeb yaj kiab hais txog kev tsim khoom ntawm LED teeb pom kev zoo rau cov yub
Qhov zoo ntawm LED teeb pom kev zoo rau cov yub
LED cog teeb yog qhov zoo tshaj plaws vim tias:
- Siv diodes, nws yog qhov ua tau kom tau txais lub teeb ci ntawm qhov xav tau ntev thiab ntev. Lawv muab ntau qhov tsis txaus ntseeg, lawv cov kev ua haujlwm tau nce mus txog yuav luag 99.9% - qhov no yog qhov pom ntawm LED teeb. Thiab qhov no txhais tau hais tias cov yub nqus nkaus xwb cov teeb nthwv dej, qhov xav tau uas lawv tau ntsib nyob rau lub sijhawm.
- Lub zog siv ntawm ib qho chaw LED muaj tsawg dua (txog 8 zaug) dua li cov teeb txawb siv. Nws tseem yog ib qho tseem ceeb uas tsis tas yuav hloov lub ntsej muag lub qhov muag teev.
- Nws muaj lub tshuab hluav taws xob tsawg, uas ua rau nws muaj kev nyab xeeb thaum dej nkag. Qhov no tso cai rau koj tso lub hauv paus kom ze txaus rau cov yub, uas, txawm li cas los xij, tsis ua rau muaj dej ntau dhau lossis, hloov dua siab tshiab, kev tso dej ntau dhau, vim hais tias cov LEDs rau cov nroj tsuag xyaum tsis ua cua sov, uas tsis tuaj yeem hais txog lub teeb hluav taws xob qub.
- Qhov tsis muaj flicker yog lwm qhov kev sib cav nyob rau hauv kev pom zoo ntawm LED teeb (thiaj li hu ua LED teeb pom kev zoo).
- Cov luminaires LED tsis tsim ultraviolet thiab infrared tawg. Qhov no yog qhov tseem ceeb tshaj plaws, vim tias qee cov nroj tsuag muaj qhov nkag siab zoo rau lawv, dhau ntawm kev cuam tshuam tsis zoo rau lawv qhov kev txhim kho tag nrho.
- Lub ecological purity ntawm LED teeb tau ntxim nyiam - lawv tsis muaj mercury, roj, lwm yam tshuaj lom, lawv cov pov tseg tsis tas yuav muaj cov xwm txheej tshwj xeeb.
- Cov kev pab cuam lub neej yog ntev heev - txog 50,000 teev.
Txhua qhov zoo ntawm LED teeb pom kev zoo rau cov yub txuas ntxiv rau cov neeg siv khoom.
Qhov laj thawj tseem ceeb rau kev faib tawm tsis txaus yog lawv cov nqi siab.
Nws tau sau tseg tias cov nyhuv ntawm LED teeb pom kev zoo rau cov yub txuas ntxiv tom qab nws tau cog rau hauv av. Los ntawm cov yub zoo li no, cov nroj tsuag zoo dua tuaj yeem loj hlob hauv cov xim, lawv pib txi txiv thiab txi cov txiv ntau dhau.
Nws tuaj yeem pom ntawm daim duab teeb uas LED pom nrog lub yoj ntawm 660 nm muab cov txiaj ntsig zoo tshaj plaws rau ob qho tib si chlorophyll synthesis, photosynthesis, thiab photomorphogenesis (muaj peev xwm los tsim cov txiv hmab txiv ntoo). Ntawd yog, lub teeb liab 650-660nm + me ntsis xiav (3: 1 piv) yuav tsum muaj nyob rau hauv cov teeb txawb LED
LED teeb rau cov nroj tsuag hauv tsev
Qhov yooj yim thiab kev siv zog tsawg tshaj plaws ntawm kev tsim cov backlight los ntawm diodes hauv tsev yog kev siv cov hlua LED.
Yuav kom ua tiav txoj haujlwm peb xav tau:
- ib lub vaj huam sib luag me me coj los ua qhov loj me rau thaj chaw yuav tsum tau ntsuas;
- ob daim LED coj - liab thiab xiav;
- fais fab mov rau muab txuas rau daim kab xev rau lub network.
Tseem Ceeb: Rau cov nroj tsuag, qhov xim sib piv ntawm diodes yuav tsum yog 1: 8, uas yog, ib feem ntawm xiav diodes, 8 seem ntawm xim liab.
LED fixtures tsis tau txuas ncaj qha mus rau 220 volt network. Koj tsuas yog siv chav tshwj xeeb uas tuaj yeem hloov qhov voltage mus rau tus nqi ntawm 12 volts (tsawg dua 24) thiab hloov hloov mus rau hauv kev hloov tam sim no.
Koj tuaj yeem yuav tus tsav tsheb uas txawv ntawm cov khoom siv hluav taws xob tshwj xeeb hauv qhov ntawd nws nruab nrog lub ntsuas hluav taws xob tam sim no thiab tsim rau qee hom LED. Tus tsav tsheb muab kev tiv thaiv ntau dua nyob rau hauv qhov xwm txheej ntawm, piv txwv, overvoltage, lossis lwm yam kev puas tsuaj.
Yuav ua li cas rau Mount LED sawb ntawm lub vaj huam sib luag?
Lub tshuab thev naus laus zis ntawm cov hlua ntawm LED rau cov yub yog qhov yooj yim heev, nws muaj peev xwm tuaj yeem nruab nws ntawm koj tus kheej.
Ua ntej so cov kab xev, koj yuav tsum ua tib zoo ntxuav lub vaj huam sib luag uas koj yuav txuas nws, los ntawm av thiab degrease.
Yog tias tsim nyog, txiav daim kab xev rau hauv ntu, txiav nws ntawm qhov chaw txhawm. Cov chaw no tau cim rau nws saum npoo. Txuas cov kab xev, soldering nrog cov xaim, lossis txuas nrog tshwj xeeb txuas.
Cov kab xev, tsis zoo li lub teeb ci LED, tsis tas yuav tsum txias ntawm tus kiv cua, txawm li cas los xij, nyob rau hauv qhov chaw sov thiab cov cua tsis txaus hauv chav, nws yuav tsum tau teeb tsa rau ntawm daim ntawv txhuas rau tshem tawm cov cua sov, vim tias overheating zoo heev txo lub neej ntawm diodes.
Ib txheej nplaum nplaum yog thov rau sab nraub qaum ntawm daim kab xev. Peb tshem tawm cov txheej txheej tiv thaiv los ntawm nws thiab nias daim kab xev rau hauv lub dav hlau ntawm lub vaj huam sib luag, thov ua lub zog me.
Thaum lub sij hawm teeb tsa, cov khoov siab ntawm cov hlua LED yuav tsum raug zam - koj tuaj yeem ua rau cov kab kev coj ua uas pub rau noj ntawm LED.
Lub vaj huam sib luag nrog LED sawb teeb rau pom kev cog ntoo yog ntsia ntawm txhais ceg thiab ntim nrog cov yub muab tso rau hauv qab nws.
Peb txiav txim siab qhov chaw nyob ntawm lub zog siv hluav taws xob, npaj nws rau kev txuas rau lub tshuab hluav taws xob 220 volt, txuas rau cov hlua LED thiab siv voltage, soj ntsuam cov polarity.
