smd led vs cob led
SMD:surface mounted devices 
COB:chip on board.There is no packaging chip affixed to the bottom plate, and then through the line bonding connected to the end of the board on the relevant point of departure, the epoxy resin epoxy drops on the chip for protection 

SMD has a specific package size

COB irregular line location?


Using COB production cost is lower than the same function SMD element


COB process is generally better than SMD.


LED SMD source is a single chip LED lamp; COB light source is the integration of multiple LED SMD chip package as a whole, than the same power LED SMD light source has the advantages of smaller volume, higher brightness.
