Nyali ya nyali ya LED ndi nyali ya LED yomwe idapangidwa kuti ifanane ndi nyali yachikhalidwe ya incandescent yokhala ndi ulusi wowonekera pofuna kukongoletsa ndi kugawa kuwala, koma ndi mphamvu yowunikira-emitting diode (LEDs). Imapanga kuwala kwake pogwiritsa ntchito ulusi wa LED, zomwe ndi mindandanda yolumikizidwa ya ma diode omwe amafanana ndi mawonekedwe a ulusi wa mababu a incandescent.
Ndiwolowa m'malo mwa mababu owoneka bwino (kapena ozizira) owoneka bwino, popeza amapangidwa ndi mawonekedwe aenvulopu omwewo, maziko omwewo omwe amakwanira zitsulo zomwezo, ndipo amagwira ntchito pamagetsi omwewo. ikayatsidwa ku bulb yomveka bwino, kapena chifukwa cha kufalikira kwawo kwa kuwala, nthawi zambiri 300 °. Amakhalanso opambana kuposa nyali zina zambiri za LED.
Babu yowunikira yamtundu wa LED idapangidwa ndi Ushio Lighting mu 2008, yomwe cholinga chake chinali kutengera mawonekedwe a babu wamba.
Mababu amasiku ano nthawi zambiri amagwiritsa ntchito nyali imodzi yayikulu kapena matrix a LED omwe amamangiriridwa ku heatsink imodzi yayikulu. Zotsatira zake, mababu awa nthawi zambiri amangotulutsa ma degree 180 m'lifupi mwake. Pofika mchaka cha 2015, mababu a LED adayambitsidwa ndi opanga angapo. mitundu ingapo ya nyali za LED, yofanana ndi mawonekedwe akayatsidwa ku ulusi wa babu wowoneka bwino, wokhazikika, komanso wofanana kwambiri mwatsatanetsatane ndi ma fillaments angapo a mababu oyambirira a Edison.
Mababu a ulusi wa LED anali ovomerezeka ndi Ushio ndi Sanyo mu 2008. Pansonic anafotokoza dongosolo lathyathyathya lomwe lili ndi ma modules ofanana ndi filament mu 2013. Ntchito zina ziwiri zodziimira patent zinaperekedwa mu 2014 koma sanapatsidwe. .Pa nthawiyo, mphamvu yowala ya ma LED inali pansi pa 100 lm/W. Pofika kumapeto kwa zaka za m'ma 2010, izi zinali zitakwera kufika pafupi ndi 160 lm/W. Chiwongolero chosavuta chomwe chimagwiritsidwa ntchito ndi mababu otsika mtengo chimapangitsa kuti kunjenjemera kuwirikiza kawiri makina osinthira magetsi, omwe amatha kukhala ovuta kuwazindikira, koma mwina amathandizira kuti maso asokonezeke komanso kupweteka kwamutu.
