COB (CHIP RAU COV PHOOJ YWG) yog dab tsi?
Ib Lub Rau Ntawm Cov Board LED Downlight muaj ib qho LED nti, teeb tsa rau ntawm lub teeb, piv rau ib qho ntawm LED zoo li SMD. Raws li ib pawg ntawm LED's tau teeb tsa nyob rau hauv ib kis, lawv yuav tsum muaj cua txias ntau dua, yog li cov cua sov loj dua, feem ntau yog ua los ntawm txhuas, yuav tsum tau muab teeb tsa kom yaj lub cua sov. Raws li cov khoom siv ntau dua yuav tsum tsim hluav taws xob COB LED ua haujlwm kub hnyiab, qhov no feem ntau nce tus nqi me ntsis.
Qhov kom zoo dua ntawm COB LED Loj hlob teeb
Yog li dab tsi xyov yog Chip-on-Board thev naus laus zis? Cov kev tsim tshwj xeeb tshaj plaws kom zoo dua ntawm COB ntim yog nws lub peev xwm kom haum cuaj lossis ntau dua LED diodes ntawm ib qho nti. LED diodes sib txuas ncaj qha mus rau cov hlaws dai, txhuas, lossis tooj liab los ua ib qho array ntawm ib qho qauv. Thaum COB LED loj hlob lub teeb raug qhib, cov diodes tawm ntawm kev tswj teeb pom kev zoo uas tsis muaj tus kheej pom lub teeb. Vim tias cov teeb no tuaj yeem ntim ntau cov nti ntxiv rau hauv thaj chaw teeb pom kev zoo, COB LED teeb pom kev zoo tshaj plaws lumen tso zis tawm ib nti thiab muab lub teeb ntom ntom ntawm cov teeb sib piv nrog lwm cov kev xaiv teeb pom kev zoo.
COB paub zoo dua lumen ib watt cim thiab lub zog txuag kub. COB chips tuaj yeem tsim nqi ntau dua lumens nrog lub zog qis nrog tsawg 80 lumens toj ib watt. Koj tuaj yeem nrhiav nws nyob hauv txhua hom qij thiab daim ntawv thov, zoo li lub flash ntawm koj lub xov tooj ntawm tes lossis lub koob yees duab thiab taw tes.
Lub teeb ntom ntom qhov nce zuj zus thaum muaj ntau dua diodes ntim ua ke hauv qhov chaw nruj. Thiab vim tias cov diodes no ua ntau dua li ib qho loj LED nti, lawv tsim kom muaj qhov sib zog ntau dua ntawm lub teeb uas nkag mus tob rau hauv cov nplooj saum toj. COB thev naus laus zis tseem khav thev xim ua cov xim hloov siab dua, uas txhais tau tias tib neeg lub qhov muag pom cov khoom hauv qab ci ntawm COB LED loj hlob teeb raws li lawv cov xim ntuj. Yog tias tsis muaj lub ntsej muag ntshav tau txuam nrog SMD LED teeb, cov neeg cog qoob loo muaj lub sijhawm yooj yim los txheeb xyuas qhov pom kev tawg uas tuaj yeem pom tias muaj pwm tua, hlawv lub teeb lossis lwm yam kev hem thawj rau kev noj qab haus huv cog.
