Ngakho-ke, emisebenzini yangaphandle, ukukhanya okumhlophe kusetshenziswa kabanzi ekuhambeni ebusuku nasekukhanyiseni ikamu.

ukukhanya okuphuzi

Ukukhanya okuphuzi okukhulunywe ngakho lapha akusikho ukukhanya okuphuzi okukhishwa yizibani zendabuko ezisebenzisa ama-incandescent bulbs. Empeleni, ukukhanya okukhishwa yizibani ze-incandescent bulbs nakho kuwuhlobo lokukhanya okumhlophe, kodwa kuphuzi okufudumele ngenxa yokushisa kombala ophansi. Ukukhanya okumhlophe kuyinhlanganisela ebomvu, e-orenji, ephuzi, eluhlaza okwesibhakabhaka, i-ingot, ne-purple. Kungumbala oxubile. Ukukhanya okuphuzi lapha kuphuzi onombala owodwa ngaphandle kokuxubana. Ukukhanya empeleni kuyigagasi le-electromagnetic le-wavelength ethile. Lapho igagasi le-electromagnetic lisakazeka emoyeni, linezinhlobo ezinhlanu: imisebe eqondile, ukubonakaliswa, ukudluliselwa, ukugqama, kanye nokuhlakazeka. Ngenxa yobude balo obuthile, ukukhanya okuphuzi akuguquki futhi kusakazeke kakhulu kunokukhanya okubonakalayo. Okusho ukuthi, ukukhanya okuphuzi kunamandla okungena, futhi ngaphansi kwezimo ezifanayo, ukukhanya okuphuzi kuhamba ibanga elide kunokukhanya okubonakalayo. Akunzima ukuchaza ukuthi kungani izibani zomgwaqo zisebenzisa ukukhanya okuphuzi kanti izibani zemoto zisebenzisa ukukhanya okuphuzi? Indawo yangaphandle ebusuku ivame ukuhambisana nomhwamuko wamanzi kanye nenkungu. Endaweni enjalo, i-flashlight ephuziiphelele.

ukukhanya okubomvu

Ukukhanya okubomvu nakho kuyisibani sombala esisetshenziswa kakhulu ochwepheshe bangaphandle, ikakhulukazi emazweni aseYurophu naseMelika. Imidlalo yokuzingela ithandwa emazweni amaningi aseYurophu naseMelika, futhiamathoshi okukhanya okubomvu zithandwa kakhulu ngabathandi bokuzingela baseYurophu naseMelika. I-retina yomuntu iqukethe izicubu ezimbili ezizwela ukukhanya: amangqamuzana e-cone namaseli e-rod. Amangqamuzana e-cone ahlukanisa imibala, kanti amangqamuzana e-rod ahlukanisa imingcele. Isizathu sokuthi abantu bangaveza umbono wombala kungenxa yamangqamuzana e-cone ku-retina. Izilwane eziningi zinezinduku noma ama-cone ambalwa kuphela, okuholela ekungazwelini kombala noma ngisho nasekungabonini kombala. Iningi lezilwane ezidla ngaphansi kwezibhamu zabazingeli baseYurophu naseMelika yilolu hlobo lwesilwane, olungenandaba nokukhanya okubomvu. Lapho bezingela ebusuku, bangasebenzisa ngokungafanele izibani ezibomvu ukuze basuse inyamazane ngaphandle kokuqaphela muntu, okuthuthukisa kakhulu ukusebenza kahle kokuzingela.

Abathandi bangaphandle basekhaya abavamile ukuba nolwazi lokuzingela, kodwa ukukhanya okubomvu kusengumbala wokukhanya owusizo kakhulu emisebenzini yangaphandle. Amehlo ayakwazi ukuzivumelanisa nezimo - lapho umbala wokukhanya ushintsha, amehlo adinga inqubo yokuzivumelanisa nezimo nokulungiswa ukuze azivumelanise nezimo. Kunezinhlobo ezimbili zokuzivumelanisa nezimo: ukuzivumelanisa nobumnyama kanye nokuzivumelanisa nokukhanya. Ukuzivumelanisa nobumnyama kuyinqubo esuka ekukhanyeni iye ebumnyameni, ethatha isikhathi eside; ukuzivumelanisa nokukhanya kuyinqubo esuka ebumnyameni iye ekukhanyeni, ethatha isikhathi esifushane. Uma sisebenzisa ithoshi elimhlophe emisebenzini yangaphandle, lapho umugqa wokubona ushintsha usuka endaweni ekhanyayo uye endaweni emnyama, ungowokuzivumelanisa nobumnyama, okuthatha isikhathi eside futhi ozobangela "ubumpumputhe" besikhathi esifushane, kuyilapho ukukhanya okubomvu kuthatha isikhathi esifushane ukuzivumelanisa nobumnyama, Kugwema inkinga "yobumpumputhe" besikhathi esifushane, okusivumela ukuthi siphathe amehlo ethu kangcono futhi silondoloze umbono ongcono wasebusuku lapho sisebenza ebusuku.

ukukhanya okuluhlaza okwesibhakabhaka
