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). 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 (socket), thiab ua haujlwm ntawm tib lub zog hluav taws xob.Lawv yuav siv tau rau lawv cov tsos, zoo ib yam. Thaum teeb rau lub teeb pom kev zoo, lossis rau lawv qhov dav ntawm lub teeb faib, feem ntau yog 300 ° .Lawv kuj muaj txiaj ntsig zoo dua li ntau lwm cov teeb ci LED.

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 teeb rau lub filament ntawm ib tug ntshiab, txheem incandescent noob, thiab heev zoo sib xws nyob rau hauv nthuav dav rau ntau yam fillaments ntawm lub thaum ntxov Edison incandescent qhov muag teev.

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 kub hauv qab LEDs. Thaum lub sij hawm ntawd, luminous efficiency ntawm LEDs yog nyob rau hauv 100 lm / W.Los ntawm lub lig 2010s, qhov no tau nce mus rau ze li ntawm 160 lm / W.Qhov yooj yim linear regulator siv los ntawm ib co cheaper qhov muag teev yuav ua rau ib co flickering ntawm ob zaug ntawm cov zaus. mains alternating tam sim no, uas yuav ua tau yooj yim mus ntes, tab sis tejzaum nws muaj feem xyuam rau qhov muag thiab mob taub hau.
