LED filament light bulb irambi re LED rakagadzirirwa kuti rifanane nerakare incandescent mwenje girobhu ine filaments inooneka yeaesthetic uye chiedza kugovera zvinangwa, asi nehunyanzvi hwepamusoro hwemwenje-emitting diodes (LEDs) .Inoburitsa mwenje wayo uchishandisa LED filaments, ayo ari akatevedzana-akabatana tambo ye diode inofanana nechitarisiko filaments yeincandescent bulbs.
Iwo akananga kutsiva akajairwa akajeka (kana frosted) incandscent bulbs, sezvo achigadzirwa nemahamvuropu maumbirwo akafanana, mabhesi akafanana anokwana masokisi mamwe chete, uye anoshanda pamagetsi mamwechete ekupa. kana yakavhenekerwa kune yakajeka incandescent girobhu, kana kune yavo yakakura angle yekugovera chiedza, kazhinji 300 °.Iwo anoshanda zvakanyanya kupfuura mamwe akawanda emwenje e LED.
Iyo LED filament mhando dhizaini girobhu remwenje rakagadzirwa naUshio Lighting muna 2008, richida kutevedzera chitarisiko chegirobhu remwenje.
Ma bulbs emazuva ano aiwanzo shandisa LED hombe kana matrix ye LED inonamirwa kune imwe hombe heatsink.Nekuda kweizvozvo, mababu aya aiwanzo gadzira danda rakafara madhigirii 180 chete. Pakazosvika 2015, ma bulbs e LED akaunzwa nevagadziri vakati wandei. Aya magadzirirwo akashandiswa. maLED filament light emitters akati wandei, akafanana pakuonekwa kana avhenekerwa kune filament yegirobhu rakajeka, rakajairwa incandescent girobhu, uye rakada kufanana zvakanyanya nekuzadza kwakawanda kwekutanga Edison incandescent bulbs.
Ma LED filament bulbs akaitwa patented naUshio naSanyo muna 2008.Pansonic akatsanangura a flat flat ane modules akafanana ne filament muna 2013. Mamwe maviri akazvimirira patent application akaiswa muna 2014 asi haana kumbopihwa.Mapepa ekutanga akaiswa aisanganisira kudonhedza kupisa pasi pemaLED. .Panguva iyoyo, kupenya kwaiita maLED kwaive pasi pe100 lm/W. Pakupera kwa2010s, izvi zvakange zvakwira kusvika pedyo ne160 lm/W. The simple linear regulator inoshandiswa nemamwe magirobhu asingadhure zvinokonzeresa kupenya kakapetwa kaviri. mains alternating current, ayo anogona kunetsa kuona, asi pamwe anokonzera eyestrain uye kutemwa nemusoro.
