Umehluko ezindlekweni zokukhiqiza zamalambu e-HPS nama-LED
Izinzuzo zezibani ze-sodium ezinengcindezi ephezulu kanye nama-LED asobala uma kuqhathaniswa nemithombo yokukhanya evamile. Lapho i-canopy yesitshalo igcwaliswa phezulu ngokukhanya kwelambu le-sodium enengcindezi ephezulu kanye nokukhanya kwe-LED okunikeza ukukhanya okubomvu nokuluhlaza okwesibhakabhaka, isitshalo singafinyelela umphumela ofanayo. I-LED idinga kuphela ukusebenzisa amandla angama-75%. Kuye kwabikwa ukuthi ngaphansi kwemibandela yokusebenza kahle kwamandla okufanayo, izindleko zokuqala zokutshala izimali ze-LED ziyi-5 ~ 10 izikhathi zedivayisi yesibani se-sodium ephezulu yokucindezela. Ngenxa yezindleko eziphakeme zokuqala, eminyakeni engu-5, izindleko zazo zonke izibani ze-molar ze-LED ziphindwe izikhathi ezingu-2 ~ 3 ngaphezu kwelambu le-sodium enengcindezi ephezulu.
Ezitshalweni ze-flowerbed, isibani se-sodium esinengcindezi ephezulu engu-150W kanye ne-14W LED zingafinyelela umphumela ofanayo okusho ukuthi i-14W LED iyonga kakhulu. I-chip yesibani sesitshalo se-LED inikeza kuphela ukukhanya okudingekayo esitshalweni. Izokwandisa ukusebenza kahle ngokususa ukukhanya okungafuneki. Ukusetshenziswa kwama-LED kumashede kudinga inani elikhulu lemishini, futhi izindleko zokutshalwa kwezimali kwesikhathi esisodwa zinkulu. Kubalimi bemifino ngabanye, ukutshala imali kunzima kakhulu. Kodwa-ke, ukonga amandla e-LED kungabuyisa izindleko eminyakeni emibili, ngakho-ke izibani zezitshalo ze-LED zekhwalithi ephezulu zizothuthukisa kakhulu izinzuzo zezomnotho ngemuva kweminyaka emibili.
Izitshalo eziluhlaza zimunca iningi lokukhanya okubomvu-owolintshi ngobude begagasi obungu-600-700 nm nokukhanya okuluhlaza okwesibhakabhaka nokukhanya okuluhlaza okwesibhakabhaka okunobude begagasi obungu-400-500 nm, futhi kudonsa kancane ukukhanya okuluhlaza ngobude obungamaza obungama-500-600 nm. Kokubili amalambu e-sodium anengcindezi ephezulu nama-LED angahlangabezana nezidingo zokukhanya zezitshalo. Inhloso yocwaningo yasekuqaleni yabacwaningi abasebenzisa ama-LED kwakuwukuthuthukisa ukusebenza kahle kwamandla kanye nokunciphisa izindleko zokusebenza nokuphatha, kanye nokwenza ngcono ikhwalithi yezitshalo ezithengiswayo. Ngaphezu kwalokho, i-LED ingasetshenziswa kabanzi ekukhiqizeni izitshalo zemithi ezisezingeni eliphezulu. Ngaphezu kwalokho, izazi ziye zaveza ukuthi ubuchwepheshe be-LED bunamandla amakhulu ekuthuthukiseni ukukhula kwezitshalo.
Isibani sesodium enengcindezi ephezulu sinenani eliphakathi futhi singamukelwa iningi labalimi. Ukusebenza kwayo kwesikhashana kungcono kunokwe-LED. Ubuchwepheshe bayo obuhambisanayo bokugcwalisa ukukhanya sebuvuthiwe futhi busasetshenziswa ngezinga elikhulu. Kodwa-ke, izibani ze-sodium ezinomfutho ophezulu zidinga ukufakwa kwama-ballasts kanye nemishini kagesi ehlobene, okwandisa izindleko zokusebenzisa. Uma kuqhathaniswa nezibani ze-sodium ezinomfutho ophezulu, ama-LED ane-spectral tunability emincane, ukuphepha nokuthembeka. Ama-LED anokuguquguquka ekuhlolweni kokusebenza kwezitshalo. Nokho, ekukhiqizeni kwangempela, izindleko ziphakeme. Ukubola okukhanyayo kukhudlwana. Futhi impilo yesevisi ingaphansi kakhulu kwenani lethiyori. Mayelana nesivuno sezitshalo, i-LED ayinayo inzuzo esobala ngaphezu kwezibani ze-sodium ezinomfutho ophezulu. Ekusetshenzisweni okukhethekile, kufanele kukhethwe ngokunengqondo ngokwezimo zangempela ezifana nezidingo zokulima, izinjongo zokufaka isicelo, umthamo wokutshala izimali kanye nokulawulwa kwezindleko.
