Qee cov ntaub ntawv ntawm LED filament teeb lub teeb

LED filament teeb lub teeb yog ib lub teeb LED uas yog tsim los zoo li ib txwm incandescent teeb lub teeb nrog pom filaments rau aesthetic thiab lub teeb tis lub hom phiaj, tab sis nrog lub high efficiency ntawm teeb pom kev zoo-emitting diodes (LEDs).Nws ua nws lub teeb siv LED filaments, uas yog series-txuas txoj hlua ntawm diodes uas zoo li nyob rau hauv tsos cov filaments ntawm incandescent teeb qhov muag teev.

Lawv yog cov hloov ncaj qha rau cov pa ntshiab (los yog frosted) qhov muag teev, raws li lawv tau ua nrog tib lub hnab ntawv cov duab, tib lub hauv paus uas haum rau tib lub qhov (sockets), thiab ua haujlwm ntawm tib qhov khoom siv hluav taws xob.Lawv yuav siv tau rau lawv cov tsos, zoo ib yam. Thaum teeb rau lub teeb pom kev pom tseeb, lossis rau lawv qhov dav ntawm lub teeb faib, feem ntau 300 °.Lawv kuj muaj txiaj ntsig ntau dua li lwm yam LED teeb.

LED filament hom tsim teeb lub teeb tau tsim los ntawm Ushio LIghting hauv xyoo 2008, npaj siab ua kom pom cov teeb pom kev zoo.

Cov qhov muag teev tam sim no feem ntau siv ib qho loj LED lossis matrix ntawm LED txuas rau ib lub heatsink loj.Raws li qhov tshwm sim, cov qij no feem ntau tsim cov nqaj tsuas yog 180 degrees dav.Los txog xyoo 2015, LED filament qhov muag teev tau qhia los ntawm ntau lub tuam txhab.Cov qauv tsim siv. ob peb LED filament teeb emitters, zoo ib yam li nyob rau hauv tsos thaum lit rau lub filament ntawm a ntshiab, tus qauv incandescent teeb, thiab zoo sib xws hauv kev nthuav dav rau ntau qhov chaw ntawm Edison incandescent qij thaum ntxov.

LED filament qhov muag teev tau patented los ntawm Ushio thiab Sanyo nyob rau hauv 2008.Pansonic tau piav qhia txog kev sib haum xeeb nrog cov qauv zoo ib yam li filament hauv xyoo 2013.Ob lwm daim ntawv thov kev ywj pheej patent tau thov rau xyoo 2014 tab sis tsis tau tso cai.Cov ntaub ntawv thaum ntxov patents suav nrog cov cua sov hauv qab cov LEDs. Thaum lub sij hawm ntawd, luminous efficiency ntawm LEDs yog nyob rau hauv 100 Los ntawm 2010s lig, qhov no tau nce mus rau ze li ntawm 160 lm / W.Qhov yooj yim linear regulator siv los ntawm qee qhov muag muag pheej yig dua yuav ua rau qee qhov flickering ntawm ob zaug ntawm qhov zaus ntawm lub mains alternating tam sim no, uas tuaj yeem nyuaj rau kev txheeb xyuas, tab sis. tejzaum nws yuav pab rau qhov muag thiab mob taub hau.
