Ukukhanyisa kwe-LEDisibe ubuchwepheshe obujwayelekile. Izibani ze-LED, amarobhothi namalambu akhona yonke indawo. Amazwe akhuthaza ukushintshwa kwamalambu e-incandescent nawe-fluorescent ezindaweni zokuhlala, ezohwebo nezimboni ezinikezwa amandla amakhulu anamalambu e-LED. Kodwa-ke, uma ukukhanyisa kwe-LED kuwukushintsha izibani ze-incandescent futhi kube indikimba eyinhloko yenkambu yokukhanyisa, ubuchwepheshe be-LED obulawulwa yi-silicon buzoba yinto ebalulekile.
Ukufiphala kuwubuchwepheshe obubaluleke kakhulu bomthombo wokukhanya. Ngoba ayikwazi ukunikeza indawo yokukhanyisa ekhululekile kuphela, kodwa futhi ifinyelele ukongiwa kwamandla nokunciphisa ukukhishwa. Ngokukhula okusheshayo kwemakethe yohlelo lokusebenza lwe-LED, ububanzi bokusebenzisa imikhiqizo ye-LED buzoqhubeka nokukhula. Imikhiqizo ye-LED kufanele ihlangabezane nezidingo zezindawo ezihlukene zohlelo lokusebenza, ngakho-ke umsebenzi wokulawula ukukhanya kwe-LED nawo uyadingeka kakhulu.
Nakuba i-Izibani ze-LEDngaphandle kokufiphala isenayo imakethe yayo. Kodwa ukusetshenziswa kobuchwepheshe bokukhanya kwe-LED akukwazi nje ukuthuthukisa umehluko, kodwa futhi kunciphise ukusetshenziswa kwamandla. Ngakho-ke, ukuthuthukiswa kobuchwepheshe be-LED dimming kuwumkhuba ongenakugwemeka. Uma i-LED ifuna ukubona ukufiphala, amandla ayo okunikezwayo kufanele akwazi ukukhipha i-engeli yesigaba esiguquguqukayo sesilawuli esilawulwa yi-silicon, ukuze kulungiswe ukugeleza okuqhubekayo kwamanje ku-LED ohlangothini olulodwa. Kunzima kakhulu ukwenza lokhu ngenkathi kugcinwa ukusebenza okujwayelekile kwe-dimmer, okuvame ukuholela ekusebenzeni kabi. Ukucwayiza nokukhanya okungalingani kwenzeka.
Ukubhekana nezinkinga zokufiphala kwe-LED, amabhizinisi amakhulu embonini afunde kancane kancane ubuchwepheshe obusezingeni eliphakeme be-LED nezisombululo. UMarvell, njengomkhiqizi ohamba phambili emhlabeni we-semiconductor, wethule isisombululo sakhe sokufiphalisa kwe-LED. Lolu hlelo lusekelwe ku-88EM8183 futhi luklanyelwe izinhlelo zokusebenza zezibani ze-LED ezifiphele ungaxhunyiwe ku-inthanethi, ezingafinyelela ubuncane bokufiphalisa u-1% okujulile. Ngenxa yokuthi i-88EM8183 isebenzisa indlela yokulawula yamanje eyinhloko eyingqayizivele, ingakwazi ukuthola ukulungiswa okuqinile kwamanje okukhiphayo ebangeni elibanzi lokokufaka le-AC.
