Sonke sinamava anjalo obomi. Ezi zisanda kuthengwaIzibane ze-LEDzihlala zikhanya kakhulu, kodwa emva kwexesha elithile, izibane ezininzi ziya kuba mnyama kwaye zibe mnyama. Kutheni izibane ze-LED zinenkqubo enjalo?

Masikubeke ezantsi namhlanje! Ukuqonda ukuba kutheni izibane ze-LED zekhaya lakho zisiba luzizi, kufuneka siqonde igama lobuchwephesha – ukubola kokukhanya kwe-LED.

Xa kusetyenziswa izibane ze-LED, kokukhona ziba mnyama kuba izibane ze-LED ziya kuba nokubola kokukhanya.

Ukuthotywa kokukhanya kweIsibane se-LEDiimveliso ziluphawu olubuthathaka lokukhanya ekugqithiseni. Okwangoku, idigri yokunciphisa ukukhanyaIimveliso ze-LEDeyenziwe ngabavelisi abakhulu be-LED emhlabeni yahlukile. Amandla aphezulu akhokelwayo nawo anokunciphisa ukukhanya, okuhambelana ngokuthe ngqo nobushushu, ikakhulu obumiselwe yi-chip, iphosphor kunye neteknoloji yokupakisha. Okwangoku, ukubola kokukhanya kwe-LED emhlophe kwimarike yenye yezona ngxaki zibalulekileyo ekuphuhliseni ukukhanya koluntu.

Ukubola kokukhanya ngokuqhelekileyo kubhekiselele kukukhanya okukhanyayo. Xa uhlawula umphezulu wesigubhu se-photosensitive, kunye nokuqokelelwa kwentlawulo phezu kwendawo ye-photosensitive, amandla anyuka ngokuqhubekayo, kwaye ekugqibeleni afikelele kwi-"saturation" enokwenzeka, eyona nto iphezulu. Amandla omphezulu aya kuncipha ngokuhamba kwexesha. Ngokuqhelekileyo, amandla okusebenza aphantsi kunobu buchule. Inkqubo yokuba amandla ayancipha ngokwendalo ngokuhamba kwexesha ibizwa ngokuba yinkqubo "yokubola okumnyama". Xa i-drum ye-photosensitive iskena kwaye ibonakaliswe, amandla ommandla omnyama (umphezulu we-photoconductor ongakhanyiswanga ngokukhanya) usekho kwinkqubo yokubola okumnyama; Kummandla oqaqambileyo (umphezulu we-photoconductor ukhanyiselwe kukukhanya), ukuxinana komthwali kumaleko wefotoconductive kukhula ngokukhawuleza, i-conductivity iyanda ngokukhawuleza, kwaye i-voltage ye-photoconductive yenziwa, intlawulo iyanyamalala ngokukhawuleza, kunye namandla omgangatho we-photoconductor nawo. iyancipha ngokukhawuleza. Kubizwa ngokuba “kukubola okukhanyayo”.
