I-silicon dimming elawulekayo ingafinyelela ukukhanya kwe-LED okuhle kakhulu

Ukukhanyisa kwe-LED sekuphenduke ubuchwepheshe obujwayelekile.Izibani ze-LED, izimpawu zethrafikhi, namalambu angaphambili akuyo yonke indawo, futhi amazwe akhuthaza ukusetshenziswa kwezibani ze-LED esikhundleni sezibani ze-incandescent nezibani ze-fluorescent ezindaweni zokuhlala, ezentengiselwano, nezimboni ezinikezwa amandla omthombo omkhulu wamandla. Kodwa-ke, uma ukukhanyisa kwe-LED kuwukuthatha indawo yama-incandescent ama-incandescent njengesisekelo senkambu yokukhanyisa, ubuchwepheshe be-thyristor dimming LED buyoba isici esithonya esibalulekile.
Ngemithombo yokukhanya, ukufiphala kuyindlela ebaluleke kakhulu. 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-LEDkumele ihlangabezane nezidingo zezindawo ezihlukene zohlelo lokusebenza, ngakho-ke, umsebenzi wokulawula ukukhanya kwe-LED nawo uyadingeka kakhulu.
Nakuba engafihliIzibani ze-LEDbasenezimakethe zabo. Kodwa-ke, ukusetshenziswa kobuchwepheshe bokufiphalisa i-LED akukwazi nje ukuthuthukisa umehluko, kodwa futhi kunciphise ukusetshenziswa kwamandla. Ngakho-ke, ukuthuthukiswa kobuchwepheshe be-LED dimming kuwumkhuba ongenakugwemeka. Uma i-LED ifuna ukuzuza ukukhanya okungacimeki, ukunikezwa kwamandla ayo kufanele ikwazi ukukhipha i-engeli yesigaba esiguquguqukayo ukusuka kusilawuli se-thyristor, ukuze ilungise ngokunye ukugeleza kwamanje okugeleza ku-LED. Kunzima kakhulu ukufeza lokhu ngenkathi kugcinwa ukusebenza okujwayelekile kwe-dimmer, okuvame ukuholela ekusebenzeni kabi. Izinkinga ezikhanyayo nezingalingani ziyenzeka.
Ebhekene nezinkinga zokufiphala kwe-LED, amabhizinisi amakhulu embonini kancane kancane acwaninga ubuchwepheshe obusezingeni eliphakeme bokufiphalisa i-LED nezisombululo. UMarvell, njengomkhiqizi ohamba phambili we-semiconductor womhlaba wonke, wethule isisombululo sakhe sokufiphala kwe-LED. Lolu hlelo lusekelwe ku-88EM8183 futhi ludizayinelwe izinhlelo zokusebenza zokukhanyisa ze-LED ezifiphele ungaxhunyiwe ku-inthanethi, ezifinyelela ukufiphala okuncane kokushona okungu-1%. Ngenxa yendlela yayo yokulawula yamanje eyingqayizivele, i-88EM8183 ingafinyelela ukulungiswa okuqinile kwamanje kokuphumayo phezu kokufakwayo okubanzi kwe-AC.
