Ngokuthuthuka okusheshayo komnotho wabantu, izibani zedolobha ziya ngokuya zikhanya.Kubonakala sengathi bambalwa abantu abasebenzisa amathoshi.Nokho, amathoshi angasisiza ukuba sihambe ngokukhululeka lapho sisebenza isikhathi esengeziwe sisendleleni egodukayo, ngezikhathi ezithile ezimnyama, lapho siqwala intaba futhi sibuka ukuphuma kwelanga ebusuku.Kukhona futhi izimboni ezikhethekile ezidinga amathoshi, njengokugada kwezokuphepha, amasosha namaphoyisa, njll. Ikakhulukazi eminyakeni yamuva nje, ngokuduma okukhulu kwemisebenzi yangaphandle, ukuvakasha kwamatende sekuphenduke umsebenzi wokuzilibazisa wabantu abangenakubalwa ngobusuku obubodwa, kanye nokukhanya okuvela isibani sesibe sibalulekile.

Kusukela amathoshi, amakhandlela, izibani zikawoyela, izibani zegesi kuya ekusungulweni kuka-Edison kwesibani, abantu abakaze bayeke isifiso sokukhanya, ubelokhu ephishekela ukukhanya kwesayensi nobuchwepheshe.Futhi ukuthuthukiswa kwesikhathi eside kwemboni ye-flash nakho kubhekene nefa nokuqhubeka kwesizukulwane ngesizukulwane, kule minyaka eyikhulu yomlando, yini eye yabhekana nethoshi?Ake sibheke khona manje!

Ngo-1877, u-Edison wasungula isibani sikagesi, esiletha ukukhanya okushisayo esintwini.Ngo-1896, umMelika ogama lakhe linguHubert wayesendleleni eya ekhaya evela emsebenzini lapho ehlangana nomngane owammemela ekhaya ukuze ajabulele into ethakazelisayo.Ngiye kokwazi nje, ekuqaleni umngane wenza ibhodwe lezimbali elikhanyayo: imbiza yembali yomngane ifakwe ngaphansi kwesibani esincane, futhi amabhethri amancane lapho ufaka amalambu amanje, amalambu akhipha ukukhanya okukhanyayo ngokulinganayo kanye nokukhanya okuphuzi okuphaphathekile kubonisa okugcwele izimbali eziqhakazayo, indawo yinhle kakhulu, kangangokuthi lapho u-Hubert naye ekhanya ngokushesha othandweni nebhodwe lezimbali.U-Hubert wayethathekile futhi ekhuthazwe yisitsha sezimbali esikhazimulayo.U-Hubert wazama ukubeka i-bulb nebhethri ku-canister encane, futhi ithoshi lokuqala lokukhanyisa elihambayo emhlabeni ladalwa.

Isizukulwane sokuqala samathoshi

Idethi: cishe ekupheleni kwekhulu le-19

Izici: I-tungsten filament bulb + ibhethri ye-alkaline, enobuso obucwebe bensimbi ukuze kuhlaliswe kuyo.

Amathoshi esizukulwane sesibili

Idethi: cishe ngo-1913

Izici: I-bulb egcwele igesi ekhethekile + ibhethri elisebenza kakhulu, i-aluminium alloy njengento yezindlu.Ukuthungwa kuhle kakhulu futhi nombala ucebile.

Amathoshi esizukulwane sesithathu

Idethi: Kusukela ngo-1963

Izici: Ukusetshenziswa kobuchwepheshe obusha bokukhipha ukukhanya - i-LED (I-Light Emitting Diode).

Amathoshi esizukulwane sesine

Isikhathi: Kusukela ngo-2008

Izici: Ubuchwepheshe be-LED + ubuchwepheshe be-IT, i-chip yokulawula ehlakaniphile eyakhelwe ngaphakathi eyakhelwe ngaphakathi, ingenziwa ngokwezifiso ngemodi yokukhanya yesofthiwe ekhethekile - i-flashlight ehlakaniphile.
