COB Teeb qhov sib txawv

Nws yog qhov zoo tshaj plaws los xaiv cov khoom siv hluav taws xob hauv ballast, vim tias cov hluav taws xob ballast muaj cov yam ntxwv ntawm kev txhim kho lub teeb thiab lub neej ntawm lub teeb. Tam sim no, tag nrho cov khoom siv hluav taws xob fluorescent ntawm lub khw yuav tsum muaj lub tshuab hluav taws xob rau hluav taws. Los ntawm kev tsom xam ntawm tus naj npawb ntawm cov nti ua haujlwm thiab kev sib xyaw ntom ntom ntawm cov nti, nws pom tau tias kev ntim khoom sib xyaw ua ke ntau-chip dawb lub teeb LED pob qhov kub thiab txias nce nrog qhov nce ntawm cov chips sib xyaw. Nws cov luminous efficiency tau txo qis nrog qhov nce ntawm cov chips sib xyaw, yog li tus naj npawb ntawm cov chips thiab kev sib xyaw ntom ntom kuj yog ib qho tseem ceeb cuam tshuam rau hauv daim ntawv thov ntawm kev ntim khoom sib xyaw. Cob “COB lub moos cov lus coj →LED ”, Koj tuaj yeem ncaj qha encapsulate ntau daim chips ntawm MCPCB ntawm cov hlau-raws li luam ntawv Circuit Court board, thiab ncaj qha dissipate lub tshav kub los ntawm substrate kom txuag tau LED ntim cov nqi, lub teeb engine module ntau lawm nqi, thiab lwm yam teeb pom kev zoo nqi. Nyob rau hauv cov nqe lus ntawm kev ua tau zoo, los ntawm tsim nyog tsim thiab microscopy, COB lub teeb qhov chaw module tuaj yeem zam qhov tsis zoo ntawm lub teeb thiab glare muaj nyob rau hauv kev sib xyaw ntawm cov khoom siv sib cais; nws tseem tuaj yeem txhim kho cov xim ntawm lub teeb pom kev zoo los ntawm kev ntxiv cov xim liab nti ua ke nrog kev sib deev. Lub luag hauj lwm ntawm COB lub teeb qhov chaw yog coj instantaneous pib voltage thiab ruaj khov voltage rau lub teeb qhov chaw. Nws tuaj yeem pom tias qhov zoo ntawm ballast yuav txiav txim siab lub neej thiab lub teeb ntawm lub teeb ncaj qha. Ntxiv nrog rau qhov ntim, lub teeb ci LED kuj muaj qhov zoo ntawm lub neej ntev. Qhov no kuj yog qhov zoo tshaj plaws. Qhov ceev ceev ntawm lub teeb teeb yog attenuation, tab sis qhov ceev yog qeeb. Los ntawm kev siv ntau yam teeb pom kev zoo, COB lub teeb qhov chaw yog tsuas yog siv rau sab hauv tsev teeb pom kev zoo xws li LED downlights, LED qab nthab teeb, thiab lwm yam. Nws qhov siab tshaj plaws ib watt suav yuav tsis tshaj 50W. Integrated high-power teeb qhov chaw yog tsuas yog siv rau txoj kev teeb pom kev zoo thiab muaj teeb pom kev zoo fixtures xws li hnub ci txoj kev teeb, LED teeb teeb, LED txoj kev teeb, LED muaj thiab tsuas teeb. SMD maj mam hloov HP lub teeb ci. HP lub teeb ci tam sim no siv rau sab nraum zoov. COB tseem muaj qee qhov chaw uas yuav tsum tau txhim kho. MCOB tam sim no tsis tau nce qib hauv theem uas twb muaj lawm. Kev koom tes los tso tawm tshaj qhov tam sim no COBoptical qhov chaw (txhuas lossis PMMA cov ntaub ntawv hauv zos, thiab lwm yam). Tam sim no, qhov loj ntawm COB lub teeb qhov chaw tsis yog tag nrho cov qauv. Thaum COB lub teeb pom kev zoo yog 10,000 teev, qhov ci tuaj yeem ncav cuag 70% txog 80% ntawm qhov pib ci ntsa iab, thiab cov teeb pom kev zoo li qub tau hloov ob zaug hauv lub sijhawm siv no. Tom qab tag nrho, lub teeb pom kev zoo tsuas yog siv 4000 teev ntawm qhov ci. Tsuas yog ib nrab ntawm qhov pib ci ntsa iab tsawg dua ib nrab ntawm kev xaiv ntawm qhov chaw dawb LED no. COB lub teeb ci tuaj yeem nkag siab yooj yim raws li lub zog siab sib xyaw ua ke ntawm lub teeb ci. Qhov chaw qhov hluav taws xob thiab cov duab loj ntawm lub teeb ci tuaj yeem tsim raws li cov khoom tsim qauv. Raws li kev lag luam tawm tswv yim hauv kuv lub teb chaws, semiconductor teeb. Txawm li cas los xij, nyob rau hauv qhov chaw tshwj xeeb ntawm LED teeb pom kev zoo, vim qhov kev ua haujlwm siab, kev ua lag luam tau monopolized los ntawm cov tuam txhab txawv teb chaws. Semiconductor teeb pom kev zoo yog kev hloov kho thev naus laus zis hauv xyoo pua no. Los ntawm qhov kev xav ntawm kev paub tab, nws tseem yog menyuam yaus. Txawm hais tias LED high-power dawb lub teeb technology tau tsim sai heev, peb lub neej nyob rau hauv LED teeb lwj, tshav kub dissipation, thiab nqi yog tseem LEDs. Tsov Tsov, qhov nrov thiab kev loj hlob ntawm cov teeb pom kev zoo. COB lub teeb ci COB (CHIP on Board) yog kho cov nti los ntawm cov nyiaj kua nplaum ntawm lub substrate, thiab cov txheej txheem kev sib txuas hluav taws xob ntawm cov nti thiab cov substrate yog siv.
