Uma kunezimvula ezinkulu, uma umbani ushayaisibani sesignali, kuzobangela ukwehluleka kwayo. Kulesi simo, kuvame ukuba nezimpawu zokusha. Izinga lokushisa eliphezulu ehlobo lizobangela nomonakalo ezibanini zesignali futhi libangele ukungasebenzi kahle. Ngaphezu kwalokho, ukuguga kwezindawo zomugqa wesignali, umthamo onganele womthwalo wezintambo, kanye nomonakalo owenziwe ngumuntu nakho kungabangela ukwehluleka kokukhanya kwesignali.
Njengoba izibani zesignali ze-LED zisetshenziswa kakhulu ngaphandle, ngezinye izikhathi zonakaliswa umbani. Ngakho-ke kufanele sivimbele kanjani ukuthi isekethe yokukhanya kwesignali ye-LED ingonakaliswa umbani?
Isengezo esibalulekile esibangela ukuthi izibani zezimpawu zethrafikhi ze-LED zivezwe ezingozini zombani umshini wokulawula izibani zezimpawu zethrafikhi ze-LED. Bese kuba imbangela yenkinga yomshini wokulawula izibani zezimpawu zethrafikhi ze-LED yisimo sezulu! Ngesikhathi sokuduma kwezulu, lina isikhathi eside nsuku zonke, lihambisana nokuduma kwezulu nombani. Ngakho-ke, singakuvimbela kanjani lokhu ukuthi kwenzeke? Izisebenzi zokwakha ezinolwazi zivame ukushisela ibha yensimbi engamamitha amabili ubude eflangeni elingaphansi kwepali yokukhanya ngemva kokufaka ipali yokukhanya yesibonakaliso sethrafikhi, bese ziyingcwaba emhlabathini. Zidlala indima yenduku yombani, zinganciphisa ngempumelelo ukulimala kokushaya kombani.
Enye indlela ukuhlanganisa ukuvikelwa kombani kwangaphandle nokuvikelwa kombani kwangaphakathi. Uhlelo lokuvikela umbani lwangaphandle lubhekisela ezintweni eziqhuba umbane ngaphandle kwesibani sethrafikhi. Lufana nenduku yombani uqobo, futhi ngesikhathi esifanayo, luklanyelwe ukufaka umqhubi ophansi kanye negridi yomhlabathi. Uhlelo lokuvikela umbani lwangaphakathi lubhekisela ekuvikelweni kwemishini engaphakathi kwesibani sethrafikhi yomgwaqo ngokuvikela i-grounding kanye nokusetha ukuvikelwa kwe-voltage. Lokhu kokubili kuyahambisana futhi kuyahambisana, ukuze kufezwe umphumela wokuvikelwa kombani okusebenzayo.
Esimweni sezulu esishisayo, izibani zesignali ze-LED nazo zinezinkinga ezithile. Izinga lokushisa eliphezulu livame ukuguga umthombo wokukhanya kwesibani sesignali, okungabangela ukuthi ukukhanya kuphenduke okuphuzi noma kulahlekelwe ukukhanya, okwenza kube nzima ngabashayeli ukubona ukukhanya kwesignali. Ngaphezu kwalokho, izinga lokushisa eliphezulu lingabangela umonakalo ohlelweni lwesekethe lwesibani sesignali, okungabangela ukuthi isibani sesignali singasebenzi. Ukuze kuqinisekiswe ukusebenza okuvamile kwezibani zezimoto emazingeni okushisa aphezulu, kudingeka kuthathwe izinyathelo zokuzivikela, njengokufaka ama-sun visor, izindawo zokungenisa umoya, njll. Ngesikhathi esifanayo, kuyadingeka ukugcina izibani zihlanzekile futhi kufakwe imithombo yokukhanya efanele amazinga okushisa aphezulu.
Izinyathelo zokuzivikela:
Ungathembeli ezinsikeni, ezindongeni, eminyango nasemafasiteleni, noma ume ngqo ngaphansi kwezibani zikagesi ngesikhathi sombani, ukuduma kwezulu, nomoya nemvula ukuze ugweme izingozi ezibangelwa ugesi obangelwa yiziphepho. Ungacashi eduze kwesigxobo sikagesi ngaphansi kwesihlahla esikhulu, futhi ungahambi noma ume endle evulekile. Zifihle ezindaweni eziphansi ngokushesha okukhulu, noma uthole umhume owomile ukuze ucashe ngangokunokwenzeka. Uma ubona umugqa wamandla aphezulu uphulwa ukushaya kombani ngaphandle, kufanele uqaphele ngalesi sikhathi, ngoba kukhona i-voltage yesinyathelo eduze kwendawo yokuphuka komugqa wamandla aphezulu, abantu abaseduze akumelwe bagijime ngalesi sikhathi, kodwa kufanele bahlanganise izinyawo zabo bagxume basuke endaweni yesehlakalo.
Uma unesifiso ngentengo yesibani sezimpawu zomgwaqo, wamukelekile ukuxhumana nomkhiqizi wezibani zezimpawu zomgwaqo uQixiang kuFunda kabanzi.
