Wasu bayanai na LED filament kwan fitila

Fitilar fitilun LED fitila ce ta LED wacce aka ƙera don kama da fitilar fitilar gargajiya ta gargajiya tare da filaments bayyane don dalilai masu kyau da kuma rarraba haske, amma tare da babban inganci na diodes masu haskaka haske (LEDs).Yana samar da hasken ta ta amfani da filament LED, waxanda ke da jeri-nauyi masu haɗin kai na diodes waɗanda suke kama da kamannin filayen fitilun fitilu masu kama da wuta.

Su ne maye gurbin kai tsaye ga kwararan fitila masu haske (ko sanyi) na al'ada, kamar yadda aka yi su da nau'ikan ambulaf iri ɗaya, sansanonin da suka dace da kwasfa iri ɗaya, kuma suna aiki a irin ƙarfin wutar lantarki iri ɗaya. a lokacin da lit zuwa haske incandescent kwan fitila, ko don fadi da kwana na haske rarraba, yawanci 300 °. Sun kuma fi dacewa fiye da sauran LED fitilu.

Ushio LIighting ne ya samar da nau'in filament nau'in filament na fitilun fitilu a cikin 2008, wanda aka yi niyya don kwaikwayi kamanni na daidaitaccen kwan fitila.

Filayen fitilu na yau da kullun suna amfani da babban LED guda ɗaya ko matrix na LED wanda aka haɗe zuwa babban heatsink ɗaya. Sakamakon haka, waɗannan kwararan fitila yawanci suna samar da katako mai faɗi kawai digiri 180. A kusan 2015, masana'antun da yawa sun gabatar da kwararan fitila na LED. filayen filaye da yawa na LED, kama da bayyanar lokacin da aka kunna su zuwa filament na fili, daidaitaccen kwan fitila mai kama da wuta, kuma kama dalla-dalla ga filla-filla da yawa na farkon Edison incandescent kwararan fitila.

LED filament kwararan fitila aka hange ta Ushio da Sanyo a 2008.Pansonic ya bayyana wani lebur tsari tare da kayayyaki kama da filament a 2013. Biyu wasu masu zaman kansu patent aikace-aikace da aka yi a 2014 amma ba a taba ba.The farkon shigar da hažžožin sun hada da zafi magudanar a karkashin LEDs. A wancan lokacin, ingantaccen ingancin LEDs ya kasance ƙasa da 100 lm/W. A ƙarshen 2010s, wannan ya tashi zuwa kusan 160 lm/W. Mai sauƙin layi mai daidaitawa da wasu kwararan fitila masu rahusa ke amfani da shi zai haifar da flickering sau biyu sau na mitar wutar lantarki. mains alternating current, wanda zai iya zama da wahala a gano shi, amma yana iya haifar da ciwon ido da ciwon kai.
