Isibani se-LED yisibani se-LED esiklanyelwe ukufana nesibani sendabuko se-incandescent esinemicu ebonakalayo ngenhloso yobuhle nokusabalalisa ukukhanya, kodwa ngokusebenza kahle okuphezulu kwama-diode okukhanyisa-emitting diode (ama-LED).Ikhiqiza ukukhanya kwayo kusetshenziswa imicu ye-LED, okuwuchungechunge oluxhunywe uchungechunge lwama-diode afana nokubukeka kwemicu yama-incandescent amalambu.
Angukushintsha okuqondile kwama-incandscent bulbs avamile (noma afriziwe), njengoba enziwa ngezimvilophu zomumo ofanayo, izisekelo ezifanayo ezilingana amasokhethi afanayo, futhi asebenza nge-voltage efanayo yokuhlinzeka. Angase asetshenziselwe ukubukeka kwawo, okufanayo. uma ikhanyiswa isibani esicwebezelayo esicacile, noma nge-engeli yayo ebanzi yokusabalalisa ukukhanya, ivamise ukuba ngu-300°. Asebenza kahle kakhulu kunamanye amalambu amaningi e-LED.
Ilambu lokukhanyisa lohlobo lwe-filament yohlobo lwe-LED lakhiqizwa ngu-Ushio Lighting ngo-2008, okuhloswe ngalo ukulingisa ukubukeka kwesibani esivamile.
Ama-Contemporary bulbs ngokuvamile asebenzisa i-LED eyodwa enkulu noma i-matrix ye-LED enamathiselwe ku-heatsink eyodwa enkulu. Ngenxa yalokho, lawa ma-bulb ngokuvamile akhiqiza i-beam engama-degree angu-180 ububanzi kuphela. Cishe ngo-2015, ama-filament bulbs e-LED aye sethulwe abakhiqizi abaningana. Le miklamo yasetshenziswa. imicu eminingi ye-LED emitters yokukhanya, efana ngokubukeka lapho ikhanyiswa kumcu wokukhanya okukhanyayo, okujwayelekile I-bulb, futhi ifana kakhulu ngemininingwane nokugcwaliswa okuningi kwama-incandescent ama-Edison asekuqaleni.
Ama-LED filament bulbs agunyazwe u-Ushio no-Sanyo ngo-2008. U-Pansonic wachaza uhlelo oluyisicaba olunamamojula afana ne-filament ngo-2013. Ezinye izicelo ezimbili ezizimele ze-patent zafakwa ngo-2014 kodwa azizange zinikezwe. .Ngaleso sikhathi, ukusebenza okukhanyayo kwama-LED kwakungaphansi kuka-100 lm/W. Ngo-2010, lokhu kukhuphuke kwafinyelela ku-160 lm/W. Isilawuli somugqa esilula esisetshenziswa ama-bulb ashibhile sizobangela ukucwayiza okuphindwe kabili imvamisa yamapayipi ashintshayo ashintshashintshayo, okungaba nzima ukukubona, kodwa okungenzeka kube nomthelela ekuqineni kwamehlo kanye nekhanda elibuhlungu.
