<prompt> Pfupisa nyaya yacho: Mapoka ezvipembenene zvinotambudza marambi emwenje usiku angava ava kuda kuva chinhu chekare. Masayendisiti akagadzira girobhu rinobudisa mwaranzi yakaderera yeruvara rwebhuruu nerwegirini, iyo yavanoti inoderedza kukwezva kwainoita mapfunde nezvimwe zvipembenene nezvikamu 20 muzana. Unyanzvi uhwu hunogonawo kuponesa upenyu munzvimbo dzinopisa dzenyika, uko zvipembenene zvinotakura hosha dzakawanda dzinogona kuuraya. Pfungwa yakajeka: Masayendisiti anoti akagadzira girobhu rinobudisa masaisai maduku ebhuruu neegirini, ayo asingasvikiri zvipembenene sezvinoita magirobhu akajairika eLED akaratidzwa Chiedza chinobudiswa nemagirobhu akajairika - kunyanya masaisai ebhuruu emagirobhu eLED - chinokwezva zvipembenene zvakasiyana-siyana, chichiita kuti zvibude usiku zviende mudzimba dzevanhu. Chinetso chacho ndechokuti zvipembenene zvakadai semamota, nhunzi dzejecha uye zvikara zvinotsvoda zvinobhururuka zvichienda kuchiedza, zvinowedzera ngozi yokubatwa nezvirwere zvinoparadzirwa nemarudzi azvo. Vanhu vane mamiriyoni matanhatu munyika yose, zvikurukuru muLatin America, vane chirwere cheChagas, chinopfuudzwa nezvikara zvinorova zvinokwezva chiedza. Nhunzi dzejecha dzinopinza vanhu utachiona hweprotozoon inouraya vanhu 20 000 pagore, nepo umhutu, hunokwezverwawo nechiedza, huchitakura marariya inouraya vanhu vanopfuura 600 000 pagore. Chiedza chinobudiswa nemarambi enguva dzose - kunyanya chiedza chebhuruu chemarambi eLED chinokwezva zvipembenene zvakasiyana-siyana, chichiita kuti zvibude usiku zviende mudzimba dzevanhu. Pano, zvipembenene zvakawanda zvinounganira pachiratidziri chechiedza muAustralia. Graphene yakagadzirirwa kuita kutanga kwayo kwekutengeserana muchimiro chegirobhu remwenje munyaya yemwedzi. Chiedza chacho chine chiedza chinonzi LED chakaumbwa netambo chakaputirwa nekabhoni yakasimba zvikuru uye chichange chichitengeswa muna 2015. Vatsvakurudzi vokuBritain vari kugadzira girobhu racho vanoti richagara kwenguva refu uye richadhura kugadzira kupfuura magirazi eLED enguva dzose, uyewo richaderedza kushandiswa kwesimba ne10 muzana. Inotaridzika sechiedza chechiedza chetsika, asi graphene yakafukidzwa inoita kuti ikwanise kutungamirira magetsi nokupisa nenzira inobudirira zvikuru, ku...  <response>: Bulb yakagadzirwa neYunivhesiti yeSouthern California naPhillips. Inobudisa chiedza chiduku chegirini nechebhuruu kuti isanyanya kukwezva zvipembenene. Chiedza chichiri kuoneka sechena chaichoicho kuvanhu saka chinogona kushandiswa mumusha. Inogona kuponesa upenyu nokudzivisa zvipembenene zvinotakura hosha kupinda mudzimba.
