Dab tsi yogChip-on-Board ("COB") LEDs?
Chip-on-Board lossis "COB" yog hais txog kev teeb tsa ntawm lub teeb liab liab nyob rau hauv kev sib cuag ncaj qha nrog lub substrate (xws li silicon carbide los yog sapphire) los tsim LED arrays.COB LEDs muaj ntau qhov zoo dua li qub LED thev naus laus zis, xws li Surface Mounted Device ("SMD") LEDs lossis Dual In-line Package ("DIP") LEDs.Qhov tshwj xeeb tshaj yog, COB thev naus laus zis tso cai rau ntau qhov ntim ntau dua ntawm LED array, lossis dab tsi cov kws tsim hluav taws xob xa mus rau kev txhim kho "lumen ntom".Piv txwv li, siv COB LED thev naus laus zis ntawm 10mm x 10mm square array ua rau 38 npaug ntau LEDs piv rau DIP LED thev naus laus zis thiab 8.5 npaug ntau dua LEDs piv rauSMD LED teebtechnology (saib daim duab hauv qab no).Qhov no ua rau muaj kev siv ntau dua thiab ntau dua uniformity ntawm lub teeb.Xwb, siv COB LED thev naus laus zis tuaj yeem txo qis hneev taw thiab siv zog ntawm LED array thaum ua kom lub teeb tso zis tas li.Piv txwv li, 500 lumen COB LED array tuaj yeem ua ntau zaus me dua thiab siv zog tsawg dua li 500 lumen SMD lossis DIP LED Array.
