Ukukhanya kwe-LEDiye yaba teknoloji eqhelekileyo. Izibane ze-LED, iirobhothi nezibane zikho kuyo yonke indawo. Amazwe akhuthaza ukutshintshwa kwezibane ze-incandescent kunye ne-fluorescent kwiindawo zokuhlala, zorhwebo kunye nezoshishino ezisetyenziswa ngamandla amakhulu kunye nezibane ze-LED. Nangona kunjalo, ukuba ukukhanya kwe-LED kukutshintsha izibane ze-incandescent kwaye zibe ngumzimba oyintloko webala lokukhanyisa, iteknoloji ye-silicon elawulwa yi-dimming LED iya kuba yinto ebalulekileyo.

Ubumnyama bubuchwephesha obubaluleke kakhulu kumthombo wokukhanya. Ngenxa yokuba ayinakubonelela kuphela indawo yokukhanya ekhululekile, kodwa iphumelele ukugcinwa kwamandla kunye nokunciphisa ukukhutshwa. Ngokukhula okukhawulezayo kwemarike yesicelo se-LED, umda wokusetyenziswa kweemveliso ze-LED nawo uya kuqhubeka nokukhula. Iimveliso ze-LED kufuneka zihlangabezane neemfuno zeendawo ezahlukeneyo zesicelo, ngoko ke umsebenzi wokulawula ukukhanya kwe-LED nawo uyimfuneko kakhulu.

Nangona iIzibane ze-LEDngaphandle kobumnyama isenayo imarike yayo. Kodwa ukusetyenziswa kwetekhnoloji yokukhanya kwe-LED ayinakuphucula kuphela umahluko, kodwa nokunciphisa ukusetyenziswa kwamandla. Ke ngoko, uphuhliso lwetekhnoloji yokukhanya kwe-LED yinto engenakuphepheka. Ukuba i-LED ifuna ukuqonda ubumnyama, unikezelo lwamandla ayo kufuneka lukwazi ukukhupha i-angle yesigaba esiguquguqukayo somlawuli olawulwa yi-silicon, ukuze kulungiswe ukuqukuqela kwangoku kwi-LED kwicala elinye. Kunzima kakhulu ukwenza oku ngelixa ugcina ukusebenza okuqhelekileyo kwe-dimmer, okuhlala kukhokelela ekusebenzeni kakubi. Ukuqhwanyaza kunye nokukhanya okungalinganiyo kwenzeka.

Ukujongana neengxaki zokufiphala kwe-LED, amashishini amakhulu kushishino ngokuthe ngcembe afunda ubuchwephesha obuphezulu be-LED kunye nezisombululo. UMarvell, njengomvelisi okhokelayo we-semiconductor wehlabathi, uphehlelele isisombululo sakhe sokuncipha kwe-LED. Esi sikimu sisekwe kwi-88EM8183 kwaye siyilelwe usetyenziso lwezibane eziluzizi ze-LED ezingasebenziyo, ezinokufikelela ubuncinci be-1% yobumnyama obunzulu. Ngenxa yokuba i-88EM8183 isebenzisa indlela eyodwa yolawulo oluphambili lwangoku, inokufezekisa ulungiso olungqongqo lwangoku kuluhlu olubanzi lwegalelo le-AC.
