Ngokukhula ngokukhawuleza koqoqosho lwabantu, izibane zesixeko ziya zikhanya ngakumbi.Kubonakala ngathi bambalwa abantu abasebenzisa iithotshi.Noko ke, iithotshi zinokusinceda sihambe ngokukhululekileyo xa sisebenza ixesha elongezelelekileyo xa sigoduka, ngamaxesha athile amnyama, xa sinyuka intaba size sibukele ukuphuma kwelanga ebusuku.Kukho kwakhona amanye amashishini ezikhethekileyo ezifuna iithotshi, ezifana zokhuseleko, ukujikeleza zomkhosi kunye namapolisa, njl. Ingakumbi kwiminyaka yakutshanje, kunye nokuthandwa kakhulu kwemisebenzi yangaphandle, uhambo lokukhempisha luye lwaba yinto yokuzonwabisa yokuzonwabisa yabantu abangenakubalwa ngobusuku, kunye nokukhanya okuvela. isibane sele sibalulekile.

Ukususela kwiitotshi, amakhandlela, izibane zeoyile, izibane zegesi ukuya ekuyilweni kwe-Edison yebhalbhu yokukhanya, abantu abazange bawuyeke umnqweno wokukhanya, baye bazama ukukhanya kwesayensi kunye nobuchwepheshe.Kwaye uphuhliso lwexesha elide loshishino lwesibane lukwafumana ilifa kunye nokuqhubekeka kwesizukulwana emva kwesizukulwana, kule minyaka ilikhulu leminyaka yembali, yintoni eye yafumana isibane?Makhe sijonge ngoku!

Ngowe-1877, u-Edison wenza isibane sombane, esizisa ukukhanya okushushu eluntwini.Ngo-1896, umMelika ogama linguHubert wayesendleleni egodukayo evela emsebenzini xa wadibana nomhlobo wakhe owammemela ekhaya ukuba azonwabele into enomdla.Waya nje ukwazi, ekuqaleni umhlobo wenza ibhodlo ekhanyayo: imbiza yentyatyambo yomhlobo ifakwe ezantsi kwebhalbhu encinci, kunye neebhetri ezincinci xa ufaka umsinga, iiglowubhu zokukhanya zikhupha ukukhanya okuqaqambileyo ngokulungeleleneyo kunye nokukhanya okuluhlaza okutyheli kubonakalisa kuzaliswe ziintyatyambo ezidubulayo, imbonakalo entle kakhulu, ukuze xa uHubert ekhazimla kwangoko ethanda imbiza yeentyatyambo.U-Hubert wayethabathekile kwaye ephefumlelwe yingqayi yeentyatyambo ekhazimlayo.U-Hubert wazama ukubeka ibhalbhu kunye nebhetri kwi-canister encinci, kwaye i-flashlight yokuqala yokukhanya ehambayo yehlabathi yenziwa.

Isizukulwana sokuqala sezibane

Umhla: malunga nokuphela kwenkulungwane ye-19

Iimpawu: Ibhalbhu ye-Tungsten filament + ibhetri yealkaline, enomgangatho ocwecwe wentsimbi ukwenzela izindlu.

Iithotshi zesizukulwana sesibini

Umhla: malunga nowe-1913

Iimpawu: I-Bulb ezaliswe ngegesi ekhethekileyo + ibhetri yokusebenza ephezulu, i-aluminium alloy njengempahla yezindlu.Ubume bugqwesile kwaye umbala utyebile.

Iithotshi zesizukulwana sesithathu

Umhla: Ukususela ngowe-1963

Iimpawu: Ukusetyenziswa kweteknoloji entsha yokukhanyisa ukukhanya - i-LED (i-Light Emitting Diode).

Iithotshi zesizukulwana sesine

Ixesha: Ukusukela ngo-2008

Iimpawu: Itekhnoloji ye-LED + itekhnoloji ye-IT, eyakhelwe-ngaphakathi evulekileyo ye-chip yokulawula ehlakaniphile, inokwenziwa ngokwezifiso ngemowudi yokukhanya yesoftware ekhethekileyo - isibane esilumkileyo.
