ʻO ke kukui filament LED he kukui LED i hoʻolālā ʻia e like me kahi ʻōpuʻu kukui incandescent kuʻuna me nā filament i ʻike ʻia no nā kumu aesthetic a me ka māmā, akā me ka kiʻekiʻe kiʻekiʻe o nā kukui-emitting diodes (LEDs). ʻO ia nā kaula i hoʻohui ʻia o nā diodes e like me ke ʻano o nā filament o nā ʻōpuʻu kukui incandescent.
He mea hoʻololi pololei ia no nā ʻōpuʻu kukui maʻamau (a i ʻole hau hau), no ka mea, ua hana ʻia me nā ʻano envelopes like, nā kumu like i kūpono i nā kumu like, a hana i ka volta hoʻolako like. Hiki ke hoʻohana ʻia no ko lākou helehelena, like ke hoʻomālamalamaʻia i kahi'ōpuʻu kukui māmā, aiʻole no ko lākou ākea ākea o ka māhele māmā, maʻamau 300 °. ʻOi aku ka maikaʻi ma mua o nā kukui LED'ē aʻe.
Ua hana ʻia kahi ʻōpuʻu kukui hoʻolālā ʻano filament LED e Ushio LIighting i ka makahiki 2008, i manaʻo ʻia e hoʻohālike i ke ʻano o kahi ʻōmole kukui maʻamau.
Hoʻohana maʻamau nā ʻōpuʻu o kēia manawa i kahi LED nui a i ʻole matrix o LED i hoʻopili ʻia i hoʻokahi heatsink nui. ʻO ka hopena, hana maʻamau kēia mau puʻupuʻu i kahi kaola he 180 degere wale nō ka laulā. ʻO kekahi mau kukui uila filament LED, e like me ka nānā ʻana i ka wā e hoʻomālamalama ʻia i ka filament o kahi ʻōpuʻu kukui maʻamau maʻamau, a like loa i nā kikoʻī me nā mea hoʻopiha lehulehu o nā ʻōpuʻu kukui Edison mua.
Ua hoʻopaʻa ʻia nā puʻupuʻu filament LED e Ushio a me Sanyo ma 2008. Ua wehewehe ʻo Pansonic i kahi hoʻonohonoho pālahalaha me nā modula e like me ka filament ma 2013. Ua waiho ʻia ʻelua mau palapala patent kūʻokoʻa ʻē aʻe ma 2014 akā ʻaʻole i ʻae ʻia. I kēlā manawa, ʻoi aku ka maikaʻi o nā LED ma lalo o 100 lm / W. Ma ka hopena o nā makahiki 2010, ua piʻi kēia i kahi kokoke i 160 lm / W. ʻO ka mea hoʻoponopono laina maʻalahi i hoʻohana ʻia e kekahi mau puʻupuʻu liʻiliʻi e hoʻopiʻi i ʻelua mau manawa o ka pinepine. ʻO ke ala ʻē aʻe, hiki ke paʻakikī ke ʻike, akā hiki ke kōkua i ka ʻeha maka a me ke poʻo.
