Ukukhanya kokukhanya kungaphezulu kuka-1000mcd, okungahlangabezana nezidingo zazo zonke izimo zezulu kanye nesibonisi esinemibala egcwele ngaphandle. Ukusebenzisa izikrini zombala we-LED kungaveza isibhakabhaka nolwandle. Isizukulwane esisha se-LED ebomvu, eluhlaza, nokuluhlaza okwesibhakabhaka ephezulu yokukhanya okuphezulu sifinyelele ukusebenza okungakaze kubonwe. 2. Ukusetshenziswa kokukhanya okuphezulu kwe-LED: 1. Inkomba yolwazi Isikhombi sesignali yemoto ye-Lantern: Ilambu lenkomba yemoto liwukuqondisa kakhulu, amalambu angemuva, namalambu amabhuleki ngaphandle kwemoto;. I-Ultra -high brightness LED isetshenziswa ezinkomba zezimoto ukuze ibe nezinzuzo eziningi uma iqhathaniswa nelambu lendabuko le-incandescent, futhi inezinhlobonhlobo zezimakethe embonini yezimoto. I-LED ingakwazi ukumelana nomthelela oqinile wemishini nokudlidliza. Isilinganiso sempilo yokusebenza kwe-MTBF ingaphezu kobukhulu obumbalwa kunesibani se-incandescent, iphakeme kakhulu kunempilo yomsebenzi wemoto uqobo, ngakho isibani sebhuleki se-LED singahlanganiswa sibe siphelele. I-substrate ekhanyelayo i-Al.gaas kanye ne-ALINGAPLED zisebenza kahle kakhulu ukuvuvukala uma kuqhathaniswa nezibani ze-incandescent ezinesihlungi sokuhlunga, ukuze amalambu amabhuleki e-LED nesibani esiqondisayo sikwazi ukusebenza kumshayeli ophansi wamanje. Amandla okushayela ajwayelekile ama-incandescent kuphela. I-1/4 yesibani, ngaleyo ndlela inciphisa imoto ekushayeleni ibanga. Amandla kagesi aphansi nawo anganciphisa umthamo nesisindo sesistimu yomugqa wangaphakathi wezimoto. Ngesikhathi esifanayo, kungase futhi kunciphise izinga lokushisa langaphakathi lokukhanya kwesignali ehlanganisiwe ye-LED, okuvumela ilensi nangaphandle ukusebenzisa ipulasitiki enomthamo ophansi wokumelana nokushisa. Isikhathi sokuphendula sesibani se-brake ye-LED singu-100NS, esifushane kunesikhathi sokuphendula sesibani se-incandescent, ukuze umshayeli ushiye isikhathi sokuphendula esengeziwe, ngaleyo ndlela athuthukise isiqinisekiso sokuphepha sokushayela. Ukukhanya nombala wenkomba yangaphandle yemoto icacisa ngokucacile. Nakuba ukukhanya kwangaphakathi kwemoto kungalawulwa yiminyango kahulumeni efanele njengokukhanya kwesignali yangaphandle, umenzi wemoto unezidingo zombala nokukhanya kwe-LED. I-GAPLED isetshenziswe emotweni, futhi ukukhanya okuphezulu kakhulu kwe-Algainp ne-Ingalen kungahlangabezana nezidingo zomkhiqizi ngokombala nokukhanya. Kusukela ekubukeni kwentengo, nakuba ukukhanya kwe-LED kusabiza kakhulu kunesibani se-incandescent, ngokombono wesistimu yonke, intengo yalezi zimbili azifani kakhulu. Ngokuthuthuka okungokoqobo kokukhanya okuphezulu kakhulu kwe-TSALGAAS kanye ne-Algainpled, amanani abelokhu ehla eminyakeni yakamuva, futhi ukwehla esikhathini esizayo kuzoba kukhudlwana. Imiyalelo yesignali yethrafikhi: Sebenzisa i-ultra -high ukukhanya kwe-LED ukuze ushintshe amalambu e-incandescent amalambu esignali yethrafikhi, amalambu axwayisayo, namalambu elogo. Ngokwezibalo zomnyango wezokuthutha wase-US ngo-1994, kuneziphambanomgwaqo ezingu-260,000 ezifakwe e-United States ukuze kufakwe amalambu ezimpawu zomgwaqo. Kudingeka okungenani izibani zesignali ezingu-12 ezibomvu, eziphuzi, neziluhlaza okwesibhakabhaka ezimpambanweni zomgwaqo ngamunye. Kukhona nezinye izimpawu zoshintsho ezimpambanweni zomgwaqo kanye namalambu axwayisayo awela umgwaqo ngaphesheya komgwaqo. Ngale ndlela, kungaba namalambu amasignali angu-20 empambana mgwaqo ngamunye, futhi kufanele akhanye ngesikhathi esifanayo. Lokhu kungalinganiselwa ukuthi amarobhothi angaba izigidi ezingu-135 ezweni lonke. Njengamanje, ukusetshenziswa kwe-ultra -high ukukhanya kwe-LED kuthathe indawo yokukhanya kwendabuko kwe-incandescent ukunciphisa ukulahleka kwamandla kuzuze imiphumela ebalulekile. I-Japan idla cishe ama-kilowatts ayisigidi esilambuni sezimpawu zomgwaqo unyaka ngamunye. Ngemuva kokusebenzisa i-ultra -high -brightness LED ukufaka izibani ze-incandescent, ukusetshenziswa kwayo kwamandla kungu-12% kuphela. Iziphathimandla ezinekhono zezwe ngalinye kufanele zenze imininingwane ehambisanayo ezweni ngalinye. Umbala wesiginali, ubukhulu obuncane bokukhanya, iphethini yesikhala se-beam, nezimfuneko zendawo yokufaka, njll. Nakuba lezi zidingo zibhalwe ngokuvumelana nezibani ze-incandescent, ukukhanya kwe-ultra -high ukukhanya kwe-LED traffic light lights okwamukelwe njengamanje kusebenza ngokuyisisekelo. Uma kuqhathaniswa namalambu e-incandescent, amalambu esignali yethrafikhi ye-LED anempilo ende yokusebenza futhi ngokuvamile angafinyelela iminyaka eyi-10. Uma kucatshangelwa umthelela wemvelo yangaphandle enokhahlo, isikhathi sokuphila esilindelekile sizoncishiswa sibe iminyaka emi-5-6. Njengamanje, ukukhanya okuphezulu kakhulu kwe-ALGIINP okubomvu, okuwolintshi, nokuphuzi kwe-LED kwenziwe ngezimboni, futhi intengo ishibhile. Uma imojula eyakhiwe ngokugqama okubomvu okuphezulu kakhulu kwe-LED ingena esikhundleni sekhanda lesignali yethrafikhi ebomvu yendabuko, isibani esibomvu se-incandescent singahluleka ngokuphepha ngenxa yesibani esibomvu se-incandescent. Umthelela obangelwa idigri encane. Ngokuvamile, imojula yesignali yethrafikhi ye-LED iqukethe izibani eziningi ze-LED ezixhunywe amaqembu amaningana. Ukuthatha imojuli yesignali yethrafikhi ye-LED engu-12 intshi ebomvu njengesibonelo, inombolo yezibani ze-LED ezixhumeke kumaqembu angu-3-9 kumaqembu angu-3-9 ngu-70-75 Lokhu (inani eliphelele lingama-210-675LED amalambu angawodwa). Uma ukukhanya okukodwa kwe-LED kwehluleka, kuzothinta kuphela isethi yamasignali. Amaqembu asele azokwehliswa abe ngu-2/3 (67%) noma 8/9 (89%) , Ngeke enze isibani sonke sesignali sihluleke njengezibani ze-incandescent. Inkinga eyinhloko yemodyuli yesignali yethrafikhi ye-LED ukuthi ukudalwa kusephezulu. Uma sithatha imojuli yesiginali yethrafikhi ye-LED engu-12-intshi ebomvu njengesibonelo, eyokuqala yasebenza ngo-1994, izindleko zayo zazingama-350 $, kwathi ngo-1996, ukusebenza kwaba ngcono ngo-1996. 12 Imojula yesiginali yethrafikhi yaseBrithani AlgainpleD, izindleko zingama-200 $. Kulindeleke ukuthi ngeke kuthathe isikhathi eside esikhathini esizayo, intengo ye-Ingan blue -green LED isignali yesignali module izoqhathaniswa ne-Algainp. Nakuba izindleko zekhanda lesignali yethrafikhi ye-incandescent ziphansi, ukusetshenziswa kwamandla kukhulu. Ukusetshenziswa kwamandla kwenhloko yesignali ye-incandescent engu-12-inch ububanzi ingu-150W. Ukusetshenziswa kwamandla ngonyaka kwesilambu sesignali ye-incandescent ezimpambanweni zemigwaqo ngu-18133kWh, okulingana no-1450 $ unyaka ngamunye. 20W, ilogo ye-LED ekujikeni empambanweni yemigwaqo ingaboniswa ngeswishi yomcibisholo. Ukusetshenziswa kwamandla kungu-9W kuphela. Ngokwezibalo, umgwaqo ngamunye ungonga u-9916kWh unyaka ngamunye, okulingana no-793 $ 793 $ unyaka ngamunye. Ngokwesilinganiso sezindleko zemojuli yesiginali yethrafikhi ye-LED ngayinye engu-200 $, imojula yesignali yethrafikhi ye-LED ebomvu isebenzisa kuphela imali kagesi elondoloziwe, futhi izindleko zokuqala zingabuyiswa ngemva kweminyaka emi-3, futhi imbuyiselo yezomnotho izotholakala ngokuqhubekayo kusukela kwezomnotho. buyela.
