Izinhlobo eziningana ezahlukene zemiklamo yezibani zekhanda
Uhlobo lwesibani sekhanda olusekelwe ezindlini zesibani sekhanda
Indlu yezibani zekhanda
Kafushane, isivikelo sesibani yisona esibamba isibani sesibani. Isivalo sesibani sihlukile kuzo zonke izimoto. Ukufakwa kwesibani nendawo yesibani kuzohluka.
1. Izibani ezikhanyisayo
Izibani ezikhanyayo yizona ezijwayelekile ezibonakala kuzo zonke izimoto, futhi kuze kube ngu-1985, lezi zazilokhu ziwuhlobo oluvame kakhulu lwezibani. Ibhalbhu esibanini esingemuva igcinwe ebhokisini elimise okwesitsha elinezibuko ezikhanyisa emgwaqweni.
Lezi zibani ezitholakala ezimotweni ezindala zinezindawo zokuhlala eziqinile. Lokhu kusho ukuthi uma isibani sisha, isibani asikwazi ukushintshwa futhi lonke ikhava yesibani kumele lishintshwa. Lezi zibani ezikhanyayo zibizwa nangokuthi izibani ezikhanyayo ezivaliwe. Ezibanini ezivaliwe, kukhona ilensi phambi kwezibani ukuze kunqunywe ukuma kwesibani esikhiqizwa yizo.
Kodwa-ke, izibani ezintsha ezikhanyisayo zinezibuko ngaphakathi kwendlu esikhundleni samalensi. Lezi zibuko zisetshenziselwa ukuqondisa ukukhanya. Ngale ntuthuko yobuchwepheshe, asikho isidingo sendlu yesibani sekhanda esivaliwe kanye nebhalbhu. Kusho nokuthi amabhalbhu angashintshwa kalula uma esha.
Izinzuzo zokukhanyisa ukukhanya
Izibani zangaphambili ezikhanyayo zishibhile.
Lezi zibani zokukhanyisa zincane ngobukhulu ngakho-ke zithatha isikhala esincane emotweni.
2. Isibani seprojektha
Njengoba ubuchwepheshe bemboni yezibani zangaphambili buthuthuka, izibani zangaphambili ziya ngokuya ziba ngcono. Isibani sangaphambili esibonakalayo siwuhlobo olusha lwesibani sangaphambili. Ngawo-1980 namuhla, isibani sangaphambili sephrojektha sesivame kakhulu, futhi iningi lamamodeli amasha ezimoto afakwe isizukulwane esaqala ukusetshenziswa ezimotweni zikanokusho. Kodwa-ke, ngalolu hlobo lwesibani sangaphambili.
Izibani zekhanda ze-projection zifana kakhulu nezibani ze-lens ezikhanyayo ngokwendlela yokuhlanganisa. Lezi zibani zekhanda zihlanganisa nebhalbhu yokukhanya evalelwe endlini yensimbi enesibuko. Lezi zibuko zisebenza njengezibonisi, zisebenza njengezibuko. Umehluko kuphela ukuthi isibani sekhanda se-projector sinelensi esebenza njengengilazi yokukhulisa. Yandisa ukukhanya kokukhanya futhi, ngenxa yalokho, izibani ze-projector zikhiqiza ukukhanya okungcono.
Ukuqinisekisa ukuthi ugongolo olukhiqizwa yisibani sekhanda sephrojektha lubekwe kahle, bahlinzeka ngesikrini esinqunyiwe. Isibani sekhanda sephrojektha sinomvamisa wokunqunywa obukhali kakhulu ngenxa yokuba khona kwalesi sivikelo esinqunyiwe.
