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 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 ukufiphala, unikezelo lwamandla ayo kufuneka lukwazi ukukhupha i-angle yesigaba esiguquguqukayo somlawuli olawulwa yisilicon, ukuze kuhlengahlengiswe ukuqukuqela kwangoku ukuya 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 sisekelwe kwi-88EM8183 kwaye yenzelwe ukucima ukukhanya kwe-LED kwi-intanethi, enokufikelela ubuncinane be-1% yobumnyama obunzulu.Ngenxa yokuba i-88EM8183 isebenzisa indlela eyodwa yolawulo oluphambili lwangoku, inokufezekisa ulungiso olungqongqo lwangoku kuluhlu olubanzi lwegalelo le-AC.
