Kuki LED ifatwa nk'urumuri rw'ikoranabuhanga rizigama ingufu?
Uko igihe cyagendaga gihita, abantu batangiye gusobanukirwa neza ikoreshwa ry’ingufu zikoreshwa mu gutanga urumuri gakondo. Nubwo batsinze cyane mu gutanga urumuri, bahuye n’ingorane zo guhindura igice kinini cy’ingufu mo ubushyuhe aho kuba urumuri, bigatuma ingufu zikoreshwa nabi cyane.
Muri iki gihe cy'ingenzi, umuvumbuzi witwa Edison yateye imbere mu gushaka kubungabunga ingufu no kugira umwuka wo guhanga udushya, atangira akazi ko kunoza amatara akoresha amashanyarazi. Nyuma y'igerageza rinini, yaje kuvumbura ubwoko bushya bw'itara rikoresha amashanyarazi - itara rikoresha incandescent. Iri vumbura ryazamuye cyane imikorere y'amatara, ariko ntiryashoboye gukemura ikibazo cy'ibanze cyo gutakaza ingufu.
Ariko, mu gihe abantu bari barimo guhangana n'iki kibazo, ikoranabuhanga rya LED (Light Emitting Diode) ryaravutse. Amatara ya LED yakoresheje ibikoresho bya semiconductor kugira ngo atange urumuri, aho gushyushya imigozi y'icyuma kugira ngo atange urumuri, bityo bihindura urwego rw'amatara. Amatara ya LED ntiyatangaga ingufu nyinshi gusa, aho ingufu hafi ya zose zahinduwe urumuri aho kuba ubushyuhe, ahubwo yanagaragaje igihe kirekire cyo kubaho no gutanga urumuri rusobanutse, biba igikundiro gishya cy'inganda z'amatara.
Kubera ko ikoranabuhanga rya LED ryakomeje gukura no gukurura abantu benshi, amatara ya LED yatangiye gukoreshwa cyane mu nzego zitandukanye. Kuva ku matara yo mu ngo kugeza ku matara y’ubucuruzi, kuva ku matara y’imodoka kugeza kuri televiziyo, ikoranabuhanga rya LED ryazanye impinduka mu nganda z’amatara. Abantu bagiye babona buhoro buhoro ko amatara ya LED atafashije gusa kuzigama ingufu ahubwo anatanga umusaruro mwiza w’amatara, bityo aba ari yo akundwa cyane n’inganda z’amatara.
Iterambere ry’ikoranabuhanga rya LED ntiryahinduye gusa imiterere y’inganda z’amatara, ahubwo ryanazanye icyizere gishya n’amahirwe ku bantu. Muri iki gihe, amatara ya LED akoreshwa cyane mu nzego zitandukanye, aduha ibisubizo by’amatara bikoresha ingufu nke, bitangiza ibidukikije, kandi binoze. Impinduka z’iri koranabuhanga zizakomeza kuyobora inganda z’amatara, bikatuzanira ahazaza heza.
Nk’uko bivugwa, “Umucyo w’impinduramatwara umurikira ahazaza.” Impinduramatwara y’ikoranabuhanga rya LED yaratangiye, kandi dutegereje ko izatuzanira ejo hazaza heza.
