Ubume bezibane zemoto -- isipili sokuhambisa ukukhanya
Idlala indima yokukhusela kuyo yonke indibano yesibane. Umqadi owenziwe ngumthombo wokukhanya we-automobile headlamp ngokusebenzisa i-reflector kunzima ukuhlangabezana neemfuno zemithetho kunye nemimiselo ye-headlamp. Isibuko sokusabalalisa ukukhanya sikwafuneka ukuba sitshintshe, sandise okanye sinciphise umqadi, ukuze senze ukukhanya okufunekayo phambi kwesithuthi. Lo msebenzi ugqitywe sisibuko sokuhambisa isibane sentloko (iglasi yesibane). Ilensi yesibane yenziwe ngeeprism ezincinci ezininzi ezingalinganiyo. Iyakwazi ukuphazamisa kwaye isasaze ukukhanya okubonakaliswe ngumbonakalisi ukuhlangabezana neemfuno zokusabalalisa ukukhanya kwesibane. Kwangaxeshanye, ikwasasaza inxalenye yokukhanya kumacala omabini, ukuze kwandiswe uluhlu lokukhanyisa isibane sentloko kwicala elithe tye kwaye ufumane isiphumo esifunwayo sokusasaza ukukhanya. Ezinye izibane zemoto zixhomekeke kuphela kulwakhiwo olukhethekileyo, imilo entsonkothileyo kunye nokuchaneka okuphezulu kokusebenza kwesibonisi ukuhlangabezana neemfuno zokusasazwa kokukhanya, kodwa ukuyila, ukubala, ukuchaneka kokufa kunye nokucubungula ubuchwepheshe bokuvelisa olu hlobo lwesibonisi kusenzima kakhulu.
Isiphumo sokukhanyisa sokukhanya sikwaxhomekeke kwi-engile yokukhanyisa ukuya kumlinganiselo othile, kwaye isixhobo sokulungelelanisa ukukhanya sinokunika umdlalo opheleleyo kumandla aso aphezulu.
