Ngokuqhelekileyo, imithombo yokukhanya ye-LED inokwahlulwa ibe ngamacandelo amabini: umntu ngamnyeUkukhanya kwe-diode ye-LEDimithombo okanye izibane ze-LED ze-diode ezinezixhasi. Kwizicelo, ngamanye amaxesha imithombo yokukhanya ye-LED yenzelwe njengemodyuli equlethe i-converter ye-DC-DC, kwaye iimodyuli ezinjalo ezinzima azikho ngaphakathi kwendawo yeengxoxo zeli nqaku. Ukuba umthombo wokukhanya we-LED okanye imodyuli yi-diode eyahlukileyo ye-LED ngokwayo, indlela eqhelekileyo yobumnyama kukulungelelanisa i-amplitudeIgalelo le-LED langoku. Ngoko ke, ukhetho lwamandla omqhubi we-LED kufuneka lubhekiselele kolu phawu. Imichilo yokukhanya ye-LED isetyenziswa ngokubanzi njenge-resistors kunye ne-LED diodes eqhagamshelwe kuthotho, ngoko ke i-voltage izinzile. Ke ngoko, abasebenzisi banokusebenzisa naluphi na unikezelo lwamandla ombane okhoyo ngokurhweba ukuqhubaImichilo yokukhanya ye-LED.

Esona sisombululo simnyama somtya we-LED kukusebenzisa imveliso yokuguquguqula ububanzi be-pulse ububanzi be-PWM ukusombulula iingxaki eziqhelekileyo zokufiphala kwe-deadtravel. Ukukhanya kwemveliso kuxhomekeke kumjikelo womthwalo wesignali yobumnyama ukuphumeza utshintsho olumnyama olunciphisa ukukhanya. Iiparamitha ezibalulekileyo zokukhetha unikezelo lwamandla okuqhuba kukuhlalutya kokuncipha kunye nokuphindaphinda kwemveliso ye-pulse wide modulation PWM. Ubuncinci besakhono sobumnyama kufuneka sibe ngaphantsi njenge-0.1% ukuphumeza isisombululo se-8-bit dimming ukuhlangabezana nazo zonke izicelo zokukhanya kwe-LED. Isiphumo sokumodareyitha kobubanzi be-pulse ye-PWM kufuneka ibe phezulu kangangoko ukuthintela iingxaki zokukhanya okudanyazayo, Ngokuhambelana noncwadi lophando lobugcisa olufanelekileyo, kuyacetyiswa ukuba ube ne-frequency okungenani engaphezulu kwe-1.25kHz ukunciphisa i-ghost flicker kwiliso lomntu.
