I-LED Street Lights VS High-Pressure Sodium Lights
Ngokuthuthuka okusheshayo komnotho womhlaba kanye nokwanda kwesidingo sikagesi, ukongiwa kwamandla kanye nokunciphisa ukungcola sekuphenduke into ekhathaza umhlaba wonke, ikakhulukazi, ukongiwa kwamandla kuyingxenye ebalulekile yokonga amandla kanye nokunciphisa ukungcola. Lesi sihloko siqhathanisa isimo samanje sokukhanyiswa komgwaqo wasemadolobheni futhi siqhathanisa nama-LED. Imingcele yezobuchwepheshe yezibani zomgwaqo kanye nezibani ze-sodium ezicindezela kakhulu zihlaziywe futhi zabalwa. Kuphetha ngokuthi ukusetshenziswa kwezibani ze-LED ekukhanyisweni komgwaqo kungasindisa amandla amaningi, futhi kunganciphisa ngokungaqondile ukukhishwa kwenani elikhulu lamagesi ayingozi, kuthuthukise ikhwalithi yemvelo, futhi kufinyelele umgomo wokonga amandla nokunciphisa ukukhishwa.
Njengamanje, imithombo yokukhanya yokukhanyisa emigwaqweni yasemadolobheni ikakhulukazi ihlanganisa izibani ze-sodium ezinengcindezi ephezulu kanye nezibani ze-fluorescent. Phakathi kwazo, amalambu e-sodium anengcindezi ephezulu asetshenziswa kakhulu ekukhanyisweni komgwaqo ngenxa yokusebenza kahle kwawo okukhanyayo kanye nekhono elinamandla lokungena kwenkungu. Kuhlanganiswe nezici zamanje zokuklama izibani zomgwaqo, ukukhanya komgwaqo okunamalambu e-sodium anengcindezi ephezulu kunalezi zinkinga ezilandelayo:
1. Indawo yokukhanyisa ikhanyisa ngokuqondile phansi, futhi ukukhanya kuphezulu. Ingafinyelela ngaphezu kuka-401 lux kweminye imigwaqo yesibili. Ngokusobala, lokhu kukhanya kungokwamandla okukhanyisa ngokweqile, okuholela ekutheni kumoshwe amandla amaningi kagesi. Ngesikhathi esifanayo, ezimpambanweni zamalambu amabili aseduze, ukukhanya kufinyelela kuphela ku-40% wesiqondiso sokukhanya okuqondile, esingakwazi ukuhlangabezana ngokuphumelelayo nesidingo sokukhanyisa.
2. Ukusebenza kahle kwe-high-pressure sodium lamp emitter cishe ku-50-60% kuphela, okusho ukuthi ekukhanyeni, cishe u-30-40% wokukhanya ukhanyiswa ngaphakathi kwesibani, ukusebenza kahle okuphelele ku-60% kuphela, lapho. kuyinto eyingozi ye-Waste.
3. Ngokweqile, ukuphila kwezibani ze-sodium ezinomfutho ophezulu kungafinyelela amahora angu-15,000, kodwa ngenxa yokuguquguquka kwegridi ye-voltage kanye nemvelo yokusebenza, impilo yesevisi ikude nokuphila kwe-theory, futhi izinga lokulimala kwezibani ngonyaka lidlula i-60%.
Uma kuqhathaniswa nezibani ze-sodium ezinomfutho ophezulu wendabuko, izibani zomgwaqo ze-LED zinezinzuzo ezilandelayo:
1. Njengengxenye ye-semiconductor, ngokombono, ukuphila okusebenzayo kwesibani se-LED kungafinyelela amahora angu-50,000, okuphakeme kakhulu kunamahora angu-15,000 ezibani ze-sodium ezicindezela kakhulu.
2. Uma kuqhathaniswa nezibani ze-sodium ezinomfutho ophezulu, inkomba yokunikeza umbala yezibani ze-LED ingafinyelela ku-80 noma ngaphezulu, eseduze kakhulu nokukhanya kwemvelo. Ngaphansi kokukhanya okunjalo, umsebenzi wokuqaphela iso lomuntu ungasetshenziswa ngempumelelo ukuze kuqinisekiswe ukuphepha emgwaqeni.
3. Uma ukukhanya komgwaqo kuvuliwe, isibani se-sodium esinengcindezi ephezulu sidinga inqubo yokushisa, futhi ukukhanya kudinga isikhathi esithile kusukela ebumnyameni kuya ekukhanyeni, okungabangeli nje ukuchithwa kwamandla kagesi, kodwa futhi kuthinte ukuthuthukiswa okuphumelelayo kohlakaniphile. ukulawula. Ngokuphambene, izibani ze-LED zingafinyelela ukukhanya okuhle ngesikhathi sokuvulwa, futhi akukho okuthiwa yisikhathi sokuqalisa, ukuze kuzuzwe ukulawulwa okuhle kokulondoloza amandla okuhlakaniphile.
4. Ngokombono wendlela yokukhanyisa, isibani se-sodium esinengcindezi ephezulu sisebenzisa i-mercury vapor luminescence. Uma umthombo wokukhanya ulahlwa, uma ungakwazi ukwelashwa ngendlela efanele, nakanjani uzobangela ukungcoliswa kwemvelo okuhambisanayo. Isibani se-LED sithatha ukukhanya kwe-solid-state, futhi ayikho into eyingozi emzimbeni womuntu. Kungumthombo wokukhanya ovumela imvelo.
5. Kusukela kusici sokuhlaziywa kwesistimu ye-optical, ukukhanya kwesibani se-sodium esinengcindezi ephezulu singokwe-omnidirectional illumination. Ngaphezulu kuka-50% wokukhanya udinga ukuboniswa isibonisi ukuze sikhanyise phansi. Ngenqubo yokubonisa, ingxenye yokukhanya izolahleka, okuzothinta ukusetshenziswa kwayo. Isibani se-LED singesokukhanyiswa kwendlela eyodwa, futhi ukukhanya kuhloswe ukuba kuqondiswe ngqo ekukhanyeni, ngakho izinga lokusebenzisa liphakeme kakhulu.
6. Ezibani ze-sodium ezicindezela kakhulu, ijika lokusabalalisa ukukhanya lidinga ukunqunywa isibonisi, ngakho-ke kukhona ukulinganiselwa okukhulu; esibanini se-LED, kwamukelwa umthombo wokukhanya osabalalisiwe, futhi umklamo ophumelelayo womthombo ngamunye wokukhanya kagesi ungabonisa isimo esihle somthombo wokukhanya wesibani, uqaphele ukulungiswa okunengqondo kwejika lokusabalalisa ukukhanya, ukulawula ukusatshalaliswa kokukhanya, futhi gcina ukukhanya kufane phakathi kwebanga lokukhanyisa elisebenzayo lesibani.
7. Ngesikhathi esifanayo, isibani se-LED sinesistimu yokulawula okuzenzakalelayo ephelele kakhulu, engalungisa ukukhanya kwesibani ngokuvumelana nezikhathi ezahlukene kanye nezimo zokukhanyisa, ezingafinyelela umphumela omuhle wokonga amandla.
Kafushane, uma kuqhathaniswa nokusetshenziswa kwezibani ze-sodium ezinomfutho ophezulu wokukhanyisa umgwaqo, izibani zasemgwaqweni ze-LED zinamandla kakhulu futhi zinobungani bemvelo.
