Umahluko phakathi koxinzelelo oluphezulu lweZibane zeSodium kunye nezibane ze-LED
Inkqubo yemveliso evaliweyo yezindlu zokugcina izityalo iya kudlala indima ebalulekileyo ekuhlangabezaneni nemfuno yokukhula kokutya kwixesha elizayo. Kwiminyaka yakutshanje, ukukhanya okwaneleyo kwe-greenhouse kuye kwaqwalaselwa ngakumbi nangakumbi. Ngakolunye uhlangothi, i-greenhouse light transmittance iyancitshiswa ngenxa yokuqhelaniswa, isakhiwo kunye neempawu eziphathekayo ze-greenhouse, kwaye kwelinye icala, izityalo ze-greenhouse azikhanyi ngokwaneleyo ngenxa yokutshintsha kwemozulu. Ngokomzekelo, imozulu eqhubekayo yemvula ebusika nasekuqaleni kwentwasahlobo, imozulu yenkungu rhoqo, njl. Isityalo sikhula ukukhanya kunokunciphisa ngokufanelekileyo okanye ukusombulula ezi ngxaki.
Izibane ze-incandescent, izibane ze-fluorescent, izibane ze-metal halide, izibane ze-sodium ezinoxinzelelo oluphezulu, kunye nezibane ezikhulayo ze-LED zonke zisetyenziswe kwi-greenhouse light supplementation. Phakathi kwezi ntlobo zemithombo yokukhanya, izibane ze-sodium ezinoxinzelelo oluphezulu zinokukhanya okuphezulu okuphezulu, ubomi benkonzo obude, ukusebenza kakuhle kwamandla ngokubanzi, kwaye zihlala kwindawo ethile yemarike, kodwa izibane ze-sodium ezinoxinzelelo oluphezulu zinokukhanya okungahambi kakuhle kunye nokhuseleko oluphantsi (kubandakanywa ne-mercury). Iingxaki ezinjengokusondela okungafikelelekiyo nazo zigqamile.
Abanye abaphengululi banesimo sengqondo esihle malunga nezibane ze-LED kwixesha elizayo okanye banokunqoba ingxaki yokungasebenzi ngokwaneleyo kwezibane eziphezulu ze-sodium. Nangona kunjalo, i-LED iyabiza, iteknoloji yokukhanya yokugcwalisa kunzima ukuyifanisa. Ithiyori yokukhanya yokuzalisa ayifezekanga, kwaye isityalo se-LED sizalisa imveliso yokukhanya iyabhidanisa, okwenza abasebenzisi babuze isicelo se-LED ekuzaliseni ukukhanya kwezityalo. Ngoko ke, iphepha lishwankathela ngokucwangcisiweyo iziphumo zophando zabaphandi bangaphambili kunye nesimo se-quo yemveliso kunye nokusetyenziswa kwabo, kwaye inikezela ngereferensi yokukhethwa kunye nokusetyenziswa kwemithombo yokukhanya kwi-greenhouse fill light.
♦ Umahluko kuluhlu lokukhanyisa kunye noluhlu lwe-spectral
Isibane se-sodium esinoxinzelelo oluphezulu sine-angle yokukhanyisa ye-360 °, kwaye ininzi yayo kufuneka ibonakaliswe ngumbonisi ukufikelela kwindawo ekhethiweyo. Ukuhanjiswa kwamandla okubonakalayo kubomvu ngokubomvu, i-yellow-green, kunye ne-blue-violet (inxalenye encinci kuphela). Ngokoyilo olwahlukileyo lokusabalalisa ukukhanya kwe-LED, i-angle yokukhanyisa esebenzayo inokwahlulwa ngokweendidi ezintathu: ≤180 °, 180 ° ~ 300 ° kunye ≥300 °. Umthombo wokukhanya we-LED unokulinganisa ubude be-wavelength, kwaye unokukhupha ukukhanya kwe-monochromatic ngamaza okukhanya amancinci, anjenge-infrared, obomvu, i-orenji, i-yellow, eluhlaza, eluhlaza okwesibhakabhaka, njl.
♦ Umahluko kwiimeko ezifanelekileyo kunye nobomi
Isibane soxinzelelo oluphezulu lwesodium ngumthombo wokukhanya wesizukulwana sesithathu. Inoluhlu olubanzi lwangoku olutshintshanayo oluqhelekileyo, ukusebenza kakuhle kokukhanya okuphakamileyo, kunye namandla anamandla okungena. Ubomi obuninzi buyi-24000h kwaye ubuncinane bunokugcinwa kwi-12000h. Xa isibane sesodium sikhanyiswa, sihamba kunye nesizukulwana sobushushu, ngoko isibane sesodium luhlobo lomthombo wobushushu. Kukwakho nengxaki yokuzicima. Njengesizukulwana sesine somthombo wokukhanya omtsha we-semiconductor, i-LED ithatha i-DC drive, ubomi bunokufikelela ngaphezu kwe-50,000 h, kwaye ukuthotywa kuncinci. Njengomthombo wokukhanya obandayo, unokukufutshane nokukhanya kwezityalo. Xa kuthelekiswa ne-LED kunye nezibane ze-sodium ezinoxinzelelo oluphezulu, kucaciswa ukuba ii-LED zikhuselekile, aziqukethe izinto ezinobungozi, kwaye zinobungane ngakumbi kwendalo.
