Izibani zangemuva ziyizibani ezimhlophe ezibekwe eduze ngangokunokwenzeka ngemuva kwesikebhe futhi zikhombisa ukukhanya okungaphazanyiswa. Umugqa ovundlile wokukhanya ongu-135° uboniswa ngaphakathi kuka-67.5° ukusuka ngqo ngemuva komkhumbi kuya ohlangothini ngalunye. Amabanga okubonakala angama-3 no-2 nmil njengoba kudingeka ngukaputeni ngokulandelana. Kusetshenziselwa ukubonisa amandla omkhumbi kanye nokukhomba amandla eminye imikhumbi, kanye nokuhlinzeka
Isibani sendawo yangemuva: isibani esisetshenziselwa ukukhombisa ukuba khona nobubanzi bemoto uma sibukwa ngemuva kwemoto;
Isignali yokujika ngemuva: isibani esisetshenziselwa ukukhombisa abanye abasebenzisi bomgwaqo ngemuva ukuthi imoto izojika kwesokudla noma kwesobunxele;
Izibani Zamabhuleki: Izibani ezibonisa abanye abasebenzisi bomgwaqo ngemuva kwemoto ukuthi imoto iyabhuleka;
Izibani zenkungu zangemuva: izibani ezenza imoto ibonakale kakhulu uma ibukwa ngemuva kwemoto enkungwini enkulu;
Ukukhanya okujikayo: Kukhanyisa umgwaqo ngemuva kwemoto futhi kuxwayise abanye abasebenzisi bomgwaqo ukuthi imoto ibuyela emuva noma isizobuyela emuva;
I-reflector yangemuva: Idivayisi ekhombisa ukuba khona kwemoto kumbukeli oseduze nomthombo wokukhanya ngokukhombisa ukukhanya okuvela emthonjeni wokukhanya wangaphandle.
Umthombo wokukhanya kwe-Incandescent
Isibani se-incandescent uhlobo lomthombo wokukhanya kwemisebe yokushisa, othembele emandleni kagesi ukufudumeza i-filament ibe yi-incandescent bese ikhipha ukukhanya, futhi ukukhanya okukhishwayo kuyi-spectrum eqhubekayo. Isibani sangemuva semoto sendabuko esinomthombo wokukhanya we-incandescent sakhiwe kakhulu izingxenye ezine: umthombo wokukhanya we-incandescent, isibonisi esisodwa se-parabolic, isihlungi kanye nesibuko sokusabalalisa ukukhanya. Izibani ze-incandescent zilula ngesakhiwo futhi kulula ukuzisebenzisa, futhi ziyimithombo yokukhanya esetshenziswa kakhulu, enomphumela ozinzile kanye noshintsho oluncane ngokushisa okuzungezile. [2]
iholele
Isimiso se-diode ekhipha ukukhanya ukuthi ngaphansi kwe-forward bias ye-junction diode, ama-electron esifundeni se-N kanye nemigodi esifundeni se-P adlula e-PN junction, bese ama-electron nemigodi kuhlangana kabusha ukuze kukhishwe ukukhanya. [2]
umthombo wokukhanya we-neon
Umgomo wokukhipha ukukhanya womthombo wokukhanya we-neon ukusebenzisa insimu kagesi kuzo zombili iziphetho zepayipi lokukhipha eligcwele igesi engasebenzi ukuze kukhiqizwe ukukhishwa okuqhubekayo. Kule nqubo, ama-athomu egesi e-noble ajabule akhipha ama-photon futhi akhiphe ukukhanya lapho ebuyela esimweni somhlaba. Ukugcwalisa amagesi ahlukene e-noble kungakhipha ukukhanya kwemibala ehlukene.
