LED filament light bulb irambi re LED rakagadzirirwa kuti rifanane nechiedza chekare chemwenje chemwenje chine filaments inooneka yeaesthetic uye chiedza kugovera zvinangwa, asi nepamusoro pekushanda kwemwenje-emitting diodes (LEDs). Inobudisa chiedza chayo uchishandisa LED filaments, ayo ari akatevedzana-akabatana tambo ye diode yakafanana nechitarisiko filaments ye incandescent mwenje bulbs.
Iwo anotsiva zvakananga kune akajairwa akajeka (kana frosted) incandscent bulbs, sezvaanogadzirwa nemahamvuropu maumbirwo akafanana, mabhesi akafanana anokodzera masokisi mamwe chete, uye anoshanda pamagetsi mamwechete ekupa. Anogona kushandiswa pakutaridzika kwawo, akafanana kana yakavhenekerwa kune yakajeka incandescent girobhu, kana kune yavo yakakura angle yekugovera chiedza, kazhinji 300 °.Iwo anoshanda zvakanyanya kudarika 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 e LED inonamirwa kune imwe hombe heatsink.Nekuda kweizvozvo, ma bulbs aya aiwanzo gadzira danda rakafara madhigirii 180 chete. Pakazosvika 2015, ma LED filament bulbs akaunzwa nevagadziri vakati wandei. Aya magadzirirwo akashandiswa. maLED filament light emitters akati wandei, akafanana pakuonekwa kana akavhenekerwa kune filament yegirobhu rakajeka, rakajairwa incandescent girobhu, uye rakada kufanana zvakanyanya nekuzadza kwakawanda kwekutanga Edison incandescent bulbs.
LED filament bulbs dzaive patented naUshio naSanyo muna 2008.Pansonic akatsanangura hurongwa hwakatsetseka nemamodules akafanana nefilament muna 2013. Zvimwe zviviri zvakasununguka zvikumbiro zvepatent zvakaiswa muna 2014 asi hazvina kumbopihwa.Mapepa ekutanga akaiswa aisanganisira kudonhedza kupisa pasi pemaLED. Panguva iyoyo, kupenya kwemagetsi eLED 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.
