Advanced Facilities Efficient ProductionLight emitting diode ( LED ) loj hlob teeb yog ib hom kev siv tshuab uas feem ntau siv los muab cov nroj tsuag thiab paj nrog txaus lub teeb kom loj hlob hauv greenhouses thiab hauv tsev. Nws yog ib qho kev hloov mus rau kev siv zog (HID) teeb pom kev zoo thiab cov hlau hiam (MH), uas feem ntau siv li 75 feem pua ntxiv zog thiab ua ntau dua kub tshaj li LED hlob tuaj. Seb kev lag luam lossis tsis yog lag luam, LED loj hlob teeb feem ntau muaj kev txuag hluav taws xob thiab yooj yim rau nruab. Lawv tuaj yeem koom ua ke nrog hnub ci thiab cua tshuab kom tau nyiaj ntau tshaj rau cov nqi hluav taws xob.
Manufacturers ntawm LED loj hlob teeb feem ntau ntsuas qhov ci nyob rau hauv lumens los yog lux. Cov kev ntsuas no xa mus rau qhov ci li cas hauv chav tsev tshwm thaum teeb ci LED qhib. Qhov no tsis yog qhia txog tias cov nroj tsuag zoo li cas yuav loj tuaj, txawm li cas los xij, vim nws tsis yog raws li cov duab thaij duab (PAR), uas yog ib feem ntawm cov nroj tsuag. Kev ntsuas ntawm micro Einstein feem ntau yog qhov zoo tshaj los ntsuas qhov kev muaj peev xwm ntawm lub teeb kom cog nroj tsuag. Cov tib neeg lub qhov muag tsis pom ntau tshaj 60 feem pua ntawm cov teeb uas LED loj hlob teeb tawm, thiab vim li no lumens thiab cov feem kev nplua nuj feem ntau yuav ua tau raws li qhov teeb ntawm cov nroj tsuag yuav nqus tau.
LED loj hlob teeb yog feem ntau muaj ntawm ib lub teeb lub teeb nrog ob peb qhov muag teev LED . Txhua lub teeb pom kev ncaj nceeg saum cov nroj tsuag lossis paj, feem ntau tsis muaj ze li ntawm 12 nti (30.48 cm). Nyob ntawm seb muaj pes tsawg tus nroj tsuag muaj, nws feem ntau siv ntau lub teeb tuav kom pab tau cov nroj tsuag loj hlob. Nws yog ib qho tseem ceeb kom tsis txhob saib ncaj qha ntawm cov teeb ci rau lub sijhawm ntev, vim tias nws yuav ua mob rau lub qhov muag.
Qhov kev pabcuam loj los siv cov teebmeem loj hlob ntawm cov teebmeem yog qhov peevxwm ua rau siab siv lub teeb nyob rau sab hauv tsev. Lub teeb no tuaj yeem ntev rau lub caij cog qoob loo uas cia cov nroj tsuag tuaj yeem sab hauv tsev ua ntej transplanting sab nraud, los yog txawm tias muaj lwm txoj hauv kev ua vaj tsev nyob. Loj hlob tseem ceeb heev rau cov nroj tsuag uas tsis tas yuav kub kom loj hlob, vim tias cov hluav taws kub cov hluav taws xob tsawg tsawg.
Rau ntau tus neeg, LED teeb yog nyiam tshaj HID teeb rau ntau lub hauv paus. Cov ballasts ntawm HID teeb yog feem ntau nrov nrov, thaum lub teeb ci feem ntau ntawm LED muaj ze li ntawm noiseless. Lub neej ntawm LED loj hlob teeb yog feem ntau li 50,000 xuab moos; lub neej ntawm HID teeb yog txawv ntawm hom, tab sis feem ntau tsawg tshaj li ib nrab ntawm LEDs. LED loj hlob teeb yog directional, hos HID teeb yuav tsum tau reflectors mus ncaj qha rau lub teeb.
