Ukusebenza ixesha elideI-LEDkuya kubangela ukuguga, ngakumbi kumandla aphezuluI-LED, ingxaki yokubola kokukhanya inzulu ngakumbi. Xa ulinganisa ubomi be-LED, akwanelanga ukuthatha umonakalo wokukhanya njengesiphelo sobomi bomboniso we-LED. Kunentsingiselo ngakumbi ukuchaza ubomi bokukhokelwa yipesenteji yokunciphisa ukukhanya kwe-LED, njenge-5% okanye i-10%.

Ukubola kokukhanya: xa uhlawula umphezulu we-drum ye-photosensitive, kunye nokuqokelela kwentlawulo phezu kombhobho we-photosensitive, amandla ayanda, 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 “kukuncipha kokukhanya” kwaye kuthoba isantya ekugqibeleni.
