Li cas muaj COB coj?

COB LED txhais nti on board LED, nws yog ib tug mus khaws nti yees, uas interconnect mus khaws nti rau substrate los ntawm conductive los sis tsis-conductive nplaum thiab ces hlau tsevneeg mus cuag nws cov kev twb kev txuas hluav taws xob. COB pob yog muab ntawm tej daim ncaj qha rau lub substrate, ces ua ke fej silica gel, cob epoxy, los yog lwm yam ntaub ntawv, ib sab daj phosphor.
Tsim txoj kev:
Thawj kauj ruam uas COB pob yog rau wafer qhov chaw taw tes rau ntawm qhov chaw substrate los thermal conductive epoxy (feem ntau yog cob epoxy tov hais nyiaj). Ob yog muab cov wafer rau hauv substrate qhov chaw mus ncaj, ces kho wafer rau lub substrate nrees los ntawm kev kho cua sov. Third yog los tsim kom muaj hluav taws xob qhov zoo sib xws ntawm cov wafer thiab cov substrate yog hlau bonding txoj kev.

COB LED zoo:
COB hom teeb ci yuav tseg tau li 30% nqi them rau daim ntawv thov, mas pw LED pob them, lub teeb cav ntau lawm cov nqi thiab cov nqi lwm yam lub teeb tis, nws yog ib qho zoo kawg thiab RESPONSIBILITIES rau daim ntaub ntawv thiab cov qib yam semiconductor teeb pom kev zoo.
Hauv kev kawm ntawv, los ntawm tus tsim meej pem thiab micro-lens molding, COB module lub teeb yuav zam lub los tsis xws luag uas taw tes thiab ntsia ntsoov lub teeb thiab lwm yam flaws existed hauv discrete hom teeb ci ntaus ntawv. Nws kuj yuav ntxiv ib co liab tej daim paab, kom zoo lub CRI no nyob hauv cov mob uas tsis muaj txo efficiency lub teeb thiab lub neej yig.
Nyob rau hauv daim ntawv thov, COB module ua zus tau tej cov chaw tsim tshuaj paus teeb pom kev zoo dua tej yam yooj yim thiab yooj yim, thiab thiaj li nqi zoo. Nyob rau hauv ntau lawm, lub tshuab uas twb muaj lawm thiab cov khoom pab yuav siab yield thiab large-scale COB module raug.
Mob Ej LED teeb pom kev zoo tom tsev khw, teeb pom kev zoo kom loj hlob zus, raws nyias inquires ntawm daim ntaub ntawv teeb pom kev zoo, peb yuav ua tau ib tug series COB hom teeb ci module rau pawg ntau lawm.
COB LED disadvantages:
COB ntim tshuab bottleneck puas yuav txhawb qhov kev cia siab rau cov hom teeb ci, thiab nws cov hauj lwm uas kub thiab txias li cas. Tiam sis, feem ntau ntawm cov kev lag luam COB ntim tuam txhab uas muag me me thiab lawv feem coob siv substrate txhuas qhov khoom ntawd. Kev cia siab rau COB txhuas yog tsawg kawg vim nws ntau dua thermal kuj, ua kom tuag LED los sis lub teeb attenuation siab yooj yim. Rau tej hub substrate yog ib qho zoo tagnrho COB khoom, tiam sis cov nqi no kuj loj, tshwj xeeb tshaj yog rau cov zog me tshaj 2W, tsis yooj yim rau koj tau txais los ntawm cov neeg.
Dua li no, qhov thov kev COB hom teeb ci rau lub lag luam yog tseem tsawg lawm los. Tsis tas li, COB LED nyob ua ib ke standardization teeb meem, tus qauv ntawm cov pob manufacturers thiab factories teeb pom kev zoo yuav tsis zoo li qub, ces ob tog tau yooj yim hauv kev koom ua ke.
Daim ntawv thov:
Tam sim no, daim ntaub ntawv tseem ceeb rau COB LED thiab mining roj, chaw teeb, txoj kev teeb ua luaj rau.
