I-bulb ye-filament ye-LED isibane se-LED eyenzelwe ukufana ne-bulb yendabuko ye-incandescent kunye ne-filaments ebonakalayo ngenjongo yobuhle kunye neenjongo zokusabalalisa ukukhanya, kodwa ngokusebenza okuphezulu kokukhanyisa-emitting diodes (i-LEDs) .Ivelisa ukukhanya kwayo isebenzisa ii-filaments ze-LED, eziluchungechunge oludityanisiweyo lwentambo yeediode ezifana nenkangeleko yeefilaments zebhalbhu zokukhanya ze-incandescent.
Zithi zithathelwe indawo ngokuthe ngqo iibhalbhu ze-incandscent eziqhelekileyo ezicacileyo (okanye ezineqabaka), njengoko zenziwe ngeemilo zemvulophu ezifanayo, iziseko ezifanayo ezilingana nesokethi ezifanayo, kwaye zisebenza kumbane wonikezelo olufanayo.Zinokusetyenziselwa inkangeleko yazo, ngokufanayo xa kulayitiwe kwibhalbhu ye-incandescent ecacileyo, okanye kwi-angle yabo ebanzi yokusabalalisa ukukhanya, ngokuqhelekileyo i-300 °.
Uhlobo lwebhalbhu yokukhanya ye-LED yaveliswa ngu-Ushio Lighting ngo-2008, ijonge ukulinganisa inkangeleko yebhalbhu yokukhanya eqhelekileyo.
Iibhalbhu zangoku ziqhele ukusebenzisa i-LED enye enkulu okanye i-matrix ye-LED encanyathiselwe kwi-heatsink enkulu. Njengesiphumo, ezi bhalbhu zivelisa umqadi obubanzi obuyi-180 degrees kuphela. izibane ezininzi ze-LED ze-filament light emitters, ezifanayo ngenkangeleko xa zikhanyiswa kwi-filament yebhalbhu ye-incandescent ecacileyo, esemgangathweni, kwaye ifana kakhulu kwiinkcukacha kwiifayili ezininzi zeebhalbhu ze-incandescent zangaphambili ze-Edison.
Iibhalbhu ze-LED ze-filament zanikwa ilungelo elilodwa lomenzi ngu-Ushio no-Sanyo ngo-2008. I-Pansonic ichaze ilungiselelo elicaba kunye neemodyuli ezifana ne-filament ngo-2013. Ezinye izicelo ezimbini ezizimeleyo ze-patent zafakwa ngo-2014 kodwa azizange zinikwe. Ngelo xesha, ukusebenza okuqaqambileyo kwee-LED kwakungaphantsi kwe-100 lm/W. Ngasekupheleni koo-2010, oku kwakunyuke ukuya kufutshane ne-160 lm/W. iintsinjana ezitshintshanayo zangoku, ezinokuba nzima ukuzibhaqa, kodwa zinegalelo kwi-eyestrain kunye nentloko.
