Ndi chitukuko chofulumira cha chuma cha anthu, magetsi a mzindawo akukhala owala kwambiri.Zikuoneka kuti anthu ochepa ndi ochepa amagwiritsa ntchito tochi.Komabe, tochi zingatithandize kuyenda momasuka pamene tikugwira ntchito yowonjezereka pobwerera kunyumba, nthaŵi zina kunja kwa mdima wa apo ndi apo, pamene tikukwera m’phiri ndi kuyang’ana kutuluka kwa dzuŵa usiku.Palinso mafakitale apadera omwe amafunikira tochi, monga chitetezo, asilikali ndi apolisi akulondera, etc. Makamaka m'zaka zaposachedwapa, ndi kutchuka kwakukulu kwa ntchito zakunja, maulendo a msasa akhala zosangalatsa za anthu osawerengeka usiku wonse, ndi kuwala kochokera. tochi yakhala yofunika kwambiri.

Kuyambira pa miuni, makandulo, nyali zamafuta, nyali za gasi mpaka pamene Edison anatulukira babu la nyali, anthu sanasiye chikhumbo cha kuunika, akhala akufunafuna kuunika kwa sayansi ndi luso lamakono.Ndipo kukula kwanthawi yayitali kwamakampani opanga tochi kukukumananso ndi cholowa ndi kupitiliza kwa mibadwomibadwo, m'zaka mazana ambiri za mbiri yakale, tochi yakumana ndi chiyani?Tiyeni tione pompano!

Mu 1877, Edison anapanga nyali yamagetsi, kubweretsa kuwala kotentha kwa anthu.Mu 1896, munthu wina wa ku America dzina lake Hubert akuchokera kuntchito anakumana ndi mnzake yemwe anamuitanira kunyumba kuti akasangalale ndi chinthu chosangalatsa.Ndinapita kungodziwa, poyamba bwenzi anapanga kuwala maluwa: bwenzi mphika wamaluwa waikidwa pansi pa babu laling'ono, ndi mabatire ang'onoang'ono pamene ntchito panopa, mababu amatulutsa kuwala wogawana ndi wotumbululuka chikasu kuwala kumaonetsa wodzazidwa ndi maluwa maluwa, malo okongola kwambiri, kotero kuti pamene Hubert nayenso nthawi yomweyo amawala m'chikondi ndi mphika wamaluwa.Hubert adachita chidwi komanso kudzozedwa ndi mphika wonyezimira wamaluwa.Hubert anayesa kuyika babu ndi batire mu kabotolo kakang'ono, ndipo tochi yoyamba yowunikira mafoni padziko lonse lapansi idapangidwa.

Mbadwo woyamba wa tochi

Tsiku: chakumapeto kwa zaka za zana la 19

Mawonekedwe: Tungsten filament babu + batire ya alkaline, yokhala ndi chitsulo chachitsulo chokhazikika.

Tochi za m'badwo wachiwiri

Tsiku: cha m'ma 1913

Mawonekedwe: Babu lodzazidwa ndi mpweya wapadera + batire yogwira ntchito kwambiri, aloyi ya aluminiyamu ngati nyumba.Kapangidwe kake ndi kokongola komanso mtundu wake ndi wolemera.

M'badwo wachitatu tochi

Date: Kuyambira 1963

Mawonekedwe: Kugwiritsa ntchito ukadaulo watsopano wotulutsa kuwala - LED (Light Emitting Diode).

M'badwo wachinayi tochi

Nthawi: Kuyambira 2008

Mawonekedwe: Ukadaulo waukadaulo wa LED + Ukadaulo wa IT, chip chotseguka chotseguka chokhazikika, chimatha kusinthidwa mwamakonda kudzera munjira yapadera yowunikira pulogalamu - tochi yanzeru.
