Izibane zendlela ephezuluyinxalenye ebalulekileyo yeziseko zophuhliso eziqinisekisa ukhuseleko ezindleleni. Ezi zibane zinkulu, ezinde zibonelela ngokukhala kwabaqhubi abahamba kwindlela ephezulu ebusuku. Kodwa ziqaqambile kangakanani ezi zibane ziphezulu? Zithini izinto ezichonga ukukhanya kwalo?
Ukuqaqamba kokukhanya kwendlela kunokwahluka ngokuxhomekeka kwizinto ezahlukeneyo, kubandakanya uhlobo lokukhanya, ukuphakama, kunye neemfuno ezithile zendlela. Ngokubanzi, izibane zeendlela eziphezulu zenzelwe ukubonelela ngenqanaba eliphezulu lokukhanyisela ukuqinisekisa ukhuseleko lokuqhuba kwaye ivumele ukubonakala kwizantya eziphezulu.
Enye yezona zinto zibaluleke kakhulu ezigqiba ukuqaqamba kokukhanya kwendlela luhlobo lokukhanya ngokwalo. Kukho iintlobo ezahlukeneyo zezibane ezisetyenziselwa ukukhanya kwendlela, nganye inesikhali sokukhanya esikhethekileyo. Olona hlobo luqhelekileyo lwesibane esisetyenziselwa ukukhanya kwendlela ephezulu zizibane ze-LED zizibane, ezaziwa ngokuqaqamba okuphezulu kunye nokuthembeka. Ezi zibane zikwasebenza ngokufanelekileyo, zibenzela ukhetho oluthandwayo lwendlela ephezulu.
Ukuphakama apho isimilo sokukhanya sifakwe khona sidlala indima ebalulekileyo ekumiseleni ukukhanya kwayo. Izibane zendlela eziphakamileyo zihlala zikhwela iinyawo ezingama-30 ukuya kwi-40 yeenyawo ngaphezulu kwendlela yokukhawulezisa kunye nokukhanyisa. Ukuphakama kukwanceda ukuthintela ilitha kwaye lusasaze ukukhanya ngakumbi kwindlela.
Ukongeza kuhlobo lwesibane kunye nokuphakama kwalo ukufakelwa, iimfuno ezithile zendlela zikwanazo nezinto ezichonga ukukhanya kwezibane eziphezulu. Umzekelo, iindlela eziphezulu ezinemilinganiselo ephezulu yesantya okanye imizobo yendlela entsonkothileyo inokufuna izibane eziqaqambileyo ukuqinisekisa ukuba abaqhubi banobume obufanelekileyo. Uyilo oluthile lwendlela, njengokuphela kwendlela kwaye ubukho bezimiqobo, ziya kuchaphazela iimfuno zokukhanya kwezibane eziphezulu.
Ke, sikhanye kangakanani izibane zendlela? Uluntu olukhanyisayo loBunjineli (i-IEs) luphuhlisa imigangatho yokukhanyisela indlela echaza amanqanaba okukhanyisa efunekayo kwiindlela ezahlukeneyo zendlela. Le migangatho isekwe kuphando olubanzi kwaye zenzelwe ukuqinisekisa ukhuseleko lokuqhuba kunye nokubonakala. Ngokubanzi, izibane zendlela ephezulu zenzelwe ukubonelela ngokukhanyisela okuncinci kwe-1 ukuya kwi-20 Kulungile, kuxhomekeke kwiimfuno ezithile zendlela.
Itekhnoloji yokukhanyisa yenze inkqubela phambili enkulu kule minyaka idlulileyo, ekhokelela kuphuhliso lwasimahla, izibane ezingakumbi zendlela. Ukukhanya okukhokelela kwezibane zediode (ze-LED), ngakumbi, ziye zaba lukhetho oludumileyo lwezibane eziphakamileyo ngenxa yokuqaqamba kunye nokusebenza kwamandla. Izibane ze-LED zisaziwa ngobomi babo obude, ukunciphisa iindleko zokulungisa ngokuhamba kwexesha.
Kubalulekile ukuba uqaphele ukuba ngelixa izibane zendlela eqaqambileyo zibalulekile ekukhuseleni ukhuseleko kunye nokubonakala, kufuneka balungelelene ukuthintela ukungcola nokukhanya. Ilitha kwizibane eziqaqambileyo kakhulu zinokuchaphazela ukubonakala komsebenzi, ngelixa ukungcola ukukhanya kunokuba nefuthe elibi kwindalo kunye nezilwanyana zasendle. Kungenxa yoko le nto kubalulekile ukuba uyile ngononophelo kwaye ufaka izibane zendlela ukubonelela ngexabiso elifanelekileyo lokukhanya ngaphandle kokubangela ukungcola okungafunekiyo okanye ungcoliseko olungeyomfuneko.
Kwisishwankathelo, izibane zendlela zenzelwe ukubonelela ngenqanaba eliphezulu lokukhanyisela ukuqinisekisa ukhuseleko kunye nokubonakala kwabaqhubi endleleni. Ukukhanya kwendlela ephezulu yendlela kuya kwahluka ngokuxhomekeka kwizinto ezinje ngohlobo lokukhanya, ukuphakama okuphakathi, kunye neemfuno ezithile zendlela. Njengoko inkqubela phambili yetekhnoloji, kulindeleke ukuba ibone ukukhanya, izibane ezingakumbi zendlela kwixa elizayo, ngakumbi ukuphucula ukhuseleko ezindleleni.
Ukuba unomdla kwizibane zendlela, wamkelekile ukunxibelelana neTianxiang ukuyaFumana isicatshulwa.
